The working principle of oil extractionThe working principle of oil extraction included geological exploration, drilling, oil extraction, and transportation. The location and nature of the oil reservoir can be determined through geological survey and geological survey. Well drilling was the process of passing a drill bit through the earth and into the oil reservoir. Oil extraction was the process of extracting oil from a reservoir. Transportation was the process of transporting the extracted oil to its destination. The specific mining methods included natural pressure mining, artificial pumping, water flooding, and gas flooding.
The working principle of 2D and 3DThe working principles of the 2D and 3D are different. You can refer to the following explanation:
Two-dimensional refers to the fictional two-dimensional world that usually appears in anime, comics, games, and other media. In the 2D world, characters, scenes, and things were flat, and the colors and shapes were simple geometric shapes. The working principle of 2D was based on the projection principle by projecting an image onto a two-dimensional plane to create a virtual world.
The three-dimensional world refers to the real world we live in. In the three-dimensional world, characters, scenes, and things were all three-dimensional, and the colors and shapes were all complicated. The working principle of the three-dimensional world was based on the principle of perspective. By observing an object from different angles and distances, one could obtain its shape, size, position, and other characteristics.
Therefore, the difference between the working principle of 2D and 3D was that they were based on different principles and presentation methods.
The working principle of the cvl transmissionThe CVS transmission was mainly composed of two variable diameter rollers (shaped like a pair of cones) and a steel belt or chain. One of the rollers was connected to the engine (power input) and the other was connected to the drive shaft (power output). During operation, the transmission ratio was changed by changing the diameter of the rollers (that is, the contact diameter between the cone and the steel belt or chain). For example, when driving at a low speed, the diameter of the input end of the wheel was smaller and the speed was higher, while the diameter of the output end of the wheel was larger and the speed was lower. As the speed of the car increased, the diameter of the two wheels changed, causing the speed of the output end of the wheel to increase. According to the different power transmitting devices, it could be divided into steel belt CVs and chain CVs. When the steel-belt CVS works, the driving cone wheel presses the side of the steel belt formed by the overlapping of the metal sheets and the metal rings to form static friction force, and the hardness between the push sheet materials is used to form thrust force, so that the steel belt drives the driven cone wheel to rotate to transmit power. When the driving wheel is clamped to the middle by the oil pressure device, the steel belt moves upward along the side wall, the circumference of the driving wheel increases, and the circumference of the driven wheel decreases, thus realizing the amplification of the engine's torque-force. The chain of the chain-type CVS was composed of a ring-shaped steel sheet and a pull piece. When it worked, the chain did not directly contact the cone wheel, but the middle rocking arm pin was pressed to achieve the transmission of the moment.

The working principle of Bluetooth is easy to understandBluetooth works by connecting devices through radio waves, allowing them to communicate over short distances. The Bluetooth device includes a Bluetooth module, a Bluetooth radio, and software. When two Bluetooth devices wanted to communicate with each other, they needed to pair up. Communication between Bluetooth devices was carried out in a short-range temporary network that could accommodate two to eight devices. After the network environment was successfully created, one device would be the master device, and the other devices would be the slave devices. Different types of Bluetooth technology had different versions of the core specifications. Bluetooth uses the 2.4-gigasecond radio frequency band for communication, which is divided into multiple small channels to avoid interference. Bluetooth's global usefulness and low power requirements made it a popular standard for connecting all kinds of devices, from consumer electronics to business applications to Internet of Things devices.
Deep-Sea Submersible Working PrincipleDifferent types of deep-sea submarines worked differently.
For some simple diving simulation devices, such as a device that put a small glass bottle half filled with water into a big bottle, when the bottle was squeezed by hand, the water would enter the small bottle mouth and squeeze the air in the bottle, making the drainage volume smaller. When the gravity was greater than the buoyancy, the water would fall. When the bottle was released, the air volume would expand, and the buoyancy would rise when the gravity was greater than the gravity.
The Dragon and other deep-sea manned submarines had ballasting iron. In the early stage, they were negative in buoyancy. After entering the sea, they began to sink. After all the work was completed, the submariners threw away the ballasting iron, became positive in buoyancy, and began to rise. This was because the deep-sea submarine was deep and the environmental pressure was high. The compressed air was not enough to force out the seawater in the air cabin, so the method of abandoning the ballasts was used to float up. Generally, the electromagnetic control was used to control the ballasting iron. If the deep-sea submarine lost power and the electromagnetic was ineffective, the ballasting iron would automatically separate from the submarine under the effect of gravity and make the submarine float. In terms of safety, Dragon's design not only included throwing away the ballasting iron, but also heavy objects such as the battery box and the sample basket. If it was entangled by seaweed, it could also abandon the robotic arm, and the alarm system could also send a float to the surface to seek rescue from the mother ship.
In addition, the Endeavor used a cable-less and unpowered floating and diving technology.
Generally speaking, the diving method of a deep-sea submarine was the same as that of a submarine. They both injected seawater into the air cabin, but the method of surfacing was different. Moreover, the deep-sea submarine was not completely autonomous. It had to rely on the mother ship to replenish energy and air.

The working principle of the ice skating carThe working principle of the ice pouring vehicle was as follows: the scraper on the ice plow of the ice pouring vehicle scraped the ice surface to ensure the smoothness of the ice surface, and then the ice chips scraped by the scraper and the ice skates were collected through the horizontal and vertical transmission system. Then, the ice washing system was used to clean the stains on the ice surface, and the sewage was pumped into the ice washing tank through the water pump. After the ice repair operation was completed, the ice chips collected in the snow tank were dumped to the designated place. In addition, there was a knife under the ice pouring cart, which could cut the potholes on the ice surface. After that, the ice surface could be melted by pouring warm water at 45 ° C. During this process, the hot water would cool down, making the ice surface very smooth and flat. If ice water was used, the new ice surface would be more brittle than the ice surface poured by hot water, which was not conducive to competition. Moreover, the entire surface of the ice surface formed by pouring warm water on the ice was naturally formed, and the relative molecules were unified and stable. While watching the Olympics, you can also read the wonderful novels related to the Olympics!
What is the simple working principle of the camera?The basic principle of the camera was to convert optical image signals into electrical signals for storage or transmission. When shooting an object, the light reflected from the object is collected by the camera lens and focused on the light receiving surface of the camera device. The light is converted into electrical energy by the camera device to obtain a "video signal". Because the optical signal was very weak, it needed to be amplified by the pre-amplifier circuit, and then processed and adjusted by various circuits. The final standard signal could be sent to a recording medium such as a video recorder, or transmitted through a transmission system or sent to a monitor for display.
In addition, the working principle of some modern cameras involved more links. For example, the Sensor image sensor in the camera first sensed the external light and converted it into an image, then transmitted the data to the SoC (System on a Chip) for unified pre-processing, such as drying, enhancing contrast, adjusting color, etc. Then it was transferred to the AI module, using pre-trained algorithms to analyze the image and classify the output results. There were also some special-purpose cameras. For example, the intelligent drip recognition camera in the factory determined whether a liquid drip event occurred through a predetermined drip detection algorithm and pattern recognition technology. The automatic water level monitoring camera continuously captured water surface images and used image processing algorithms to extract water level information.

Working principle of retro reflective sensorThe retro reflective sensor is composed of a light transmitter and a light receiver. The transmitter emitted a beam of light, which was reflected and received by the receiver. When an object was detected, the object would block the light, causing the light received by the receiver to weaken or disappear. Then, according to the intensity of the light received by the receiver, it was determined whether the object was detected. This type of sensor is suitable for detecting opaque objects and is not easily disturbed by environmental light. When it was used, the light transmitter and light receiver needed to be installed on the same side, and the object was placed on the other side of the sensor.

Working Principle of Rain Interception Hanging BasketThe working principle of the rainwater intercepting hanging basket device was to use gravity to separate the dirt in the rainwater and settle it at the bottom of the basket, while the clear water flowed out from the top of the basket. The device collected rainwater and sewage through a basket-like object, while preventing sewage from entering the rainwater pipe, reducing environmental pollution. This device usually consisted of a basket and a support frame. The basket was usually made of plastic or stainless steel, and its shape and size were designed according to actual needs. When using this device, the bottom of the basket needed to be cleaned regularly to prevent blockage and odor. At the same time, the integrity and cleanliness of the device needed to be checked regularly to ensure that it was functioning properly.
