This, in turn, drives the rotating block to adjust the opening and closing of the moving baffle through the cooperation of the limiting plate and the moving baffle. When the counterweight descends, the cooperation of the buffer cotton and the damper effectively alleviates the impact force. This reduces human intervention and achieves fully automatic control of the airlock adjustment process, making it easy to operate.

[0016] 3. This invention collects environmental data such as wind speed, pressure difference, temperature and humidity in real time through a sensor module and transmits the data to the control module.

[0033] Working Principle: When using this device, the electric guide rail 802 inside the sleeve rod 801 is activated, which drives the electric slider 803 to move, thereby causing the counterweight 804 to move outside the sleeve rod 801. The position of the counterweight 804 can be adjusted to regulate the gravity, which in turn rotates the turntable 705, causing the positioning rod 706 to rotate on the inner wall of the ventilation box 1. This causes the rotating block 704 to rotate, and one end of the rotating block 704 drives the limiting plate 703 to rise. The limiting baffle 701 cooperates with the moving baffle 702, allowing the moving baffle 702 to move along the inner wall of the limiting baffle 701, thus adjusting the opening and closing size of the moving baffle 702. The movement of the counterweight 804 causes the turntable 705 to rotate, causing the counterweight 804 to descend. This movement is achieved through the interaction of the buffer cotton 903 and the damper 902. The mutual cooperation of these elements can effectively buffer the impact force by causing the counterweight 804 to drop. During the rotation of the positioning rod 706, it synchronously drives the pulley 1001 to rotate, thereby causing the pulley 1002 to rotate synchronously through the belt transmission. The pulley 1002 drives the bevel gear 1003 through the limit rod 1005. Thus, through the meshing of the bevel gear 1003 and the bevel gear 1004, the connecting rod 303 is driven to rotate, thereby driving the turntable 304 to rotate. This causes the protrusion 305 to strike the bottom of the filter screen 302, causing the filter screen 302 to vibrate against the inner wall of the fixed block 301. This vibration cleans the dust from the filter screen 302, and the cleaned dust passes through the cleaning groove 306. The air enters the collection box 307 for centralized processing. This intelligent air damper adjustment system collects environmental data such as wind speed, pressure difference, temperature and humidity through the sensor module and transmits it to the control module. The core controller performs real-time analysis in conjunction with the control algorithm to generate precise instructions, thereby driving the module to quickly adjust the opening and closing of the air damper according to the instructions. It has precise positioning and mechanical recovery functions to ensure safety. In conjunction with the data interaction module, it realizes data transmission and human-machine interaction with the main control system, and supports remote monitoring and recording storage.
