In addition, the working environment inside the coal mine is poor, and the temperature difference with the outside world is large, which is not conducive to the health of the workers. Therefore, there is an urgent need for a coal mine ventilation equipment to solve the above problems. Utility Model Content

[0039] In this embodiment, when in use, the external power supply is turned on. When stones or soil fall on the well wall body 1, the fallen objects fall on the noise reduction pad 7. The gravitational potential energy causes the noise reduction pad 7 and the mounting plate 6 to move toward the ventilation pipe 3. When the mounting plate 6 moves, it drives the round rod 5 to slide inside the mounting tube 4. At the same time, the mounting plate 6 compresses the elastic member 9. After the elastic member 9 is deformed, it rebounds and drives the mounting plate 6 and the noise reduction pad 7 to reciprocate vertically to form vibration, which is convenient for shaking off the fallen objects on the noise reduction pad 7. At the same time, when the noise reduction pad 7 is hit by the fallen objects, it deforms and absorbs kinetic energy. With the contraction of the elastic member 9, it is convenient to play a buffering and protective role, which is beneficial to protect the mounting plate 6 and the noise reduction pad 7 from being damaged by the fallen objects, and further protect the mounting plate 6 shows the internal structure of the ventilation pipe 3 below. The staff controls the motor 307 to work. When the motor 307 works, it drives the main gear 306 to rotate. When the main gear 306 rotates, it drives the slave gear 303 to rotate. When the slave gear 303 rotates, it drives the spline tube 304 to rotate. When the spline tube 304 rotates, it drives the spline rod 305 and the rotating shaft 301 to rotate. When the rotating shaft 301 rotates, it drives the fan blades 302 to rotate, so as to accelerate the air circulation inside the ventilation pipe 3 on the fixed frame 2. When the spline rod 305 rotates, it drives the round block 8 to rotate on the inner wall of the mounting plate 6. When the round block 8 rotates, it drives the two cleaning rods 801 to rotate on the noise reduction pad 7, so as to clean the debris on the noise reduction pad 7 and avoid the accumulation of debris.

[0040] Embodiment 2, as Figure 1 - Figure 4As shown, a noise reduction pad 7 is fixedly installed on one end of the mounting plate 6 close to the cleaning rod 801, and a plurality of round rods 5 are fixedly installed on the side of the mounting plate 6 away from the noise reduction pad 7. A mounting tube 4 is slidably installed on one end of the plurality of round rods 5 away from the mounting plate 6. One end of the plurality of mounting tubes 4 away from the round rods 5 is fixedly installed on one end of the ventilation pipe 3.

A trigger assembly 308 is fixedly installed at one end of the ventilation pipe 3 close to the heater 10, and a controller 309 is fixedly installed at one end of the ventilation pipe 3 close to the trigger assembly 308, and the controller 309 is electrically connected to the heater 10.

[0041] In this embodiment, when in use, the trigger assembly 308 includes a storage tube, a telescopic rod, a piston and mercury. The mercury is blocked by the piston inside the storage tube to prevent leakage. The outer surface of the piston is slidably connected to the inner wall of the storage tube. The end of the piston away from the mercury is fixedly installed at one end of the telescopic rod. When the temperature is high, the expansion of mercury drives the piston and the telescopic rod to move toward the controller 309. When the telescopic rod in the trigger assembly 308 contacts the controller 309, the controller 309 controls the heater 10 to stop working and stop heating the coal mine. When the temperature in the coal mine is low, the controller 309 does not contact the trigger assembly 308. The controller 309 controls the heater 10 to work, which is convenient for heating the air passing through the heater 10, which is beneficial to increase the temperature in the coal mine and avoid the excessive temperature difference between the inside and the outside to affect the personal health of the workers.

[0042] Working principle: When in use, the external power supply is turned on. When stones or soil fall on the well wall body 1, the fallen objects fall on the noise reduction pad 7. The gravitational potential energy causes the noise reduction pad 7 and the mounting plate 6 to move toward the ventilation pipe 3. When the mounting plate 6 moves, it drives the round rod 5 to slide inside the mounting tube 4. At the same time, the mounting plate 6 compresses the elastic member 9. After the elastic member 9 is deformed, it rebounds and drives the mounting plate 6 and the noise reduction pad 7 to reciprocate vertically to form vibration, which is convenient for shaking off the fallen objects on the noise reduction pad 7. At the same time, when the noise reduction pad 7 is hit by the fallen objects, it deforms and absorbs kinetic energy, which cooperates with the contraction of the elastic member 9 to facilitate starting. The buffer protection is beneficial to protect the mounting plate 6 and the noise reduction pad 7 from being damaged by falling objects, and at the same time further protects the internal structure of the ventilation pipe 3 below the mounting plate 6. The staff controls the motor 307 to work. When the motor 307 works, it drives the main gear 306 to rotate. When the main gear 306 rotates, it drives the slave gear 303 to rotate. When the slave gear 303 rotates, it drives the spline tube 304 to rotate. When the spline tube 304 rotates, it drives the spline rod 305 and the rotating shaft 301 to rotate. When the rotating shaft 301 rotates, it drives the fan blades 302 to rotate, accelerating the internal structure of the ventilation pipe 3 on the fixed frame 2. The air circulates, and when the spline rod 305 rotates, it drives the round block 8 to rotate on the inner wall of the mounting plate 6. When the round block 8 rotates, it drives the two cleaning rods 801 to rotate on the noise reduction pad 7, so as to clean the debris on the noise reduction pad 7 and avoid the accumulation of debris. When in use, the trigger assembly 308 includes a storage tube, a telescopic rod, a piston and mercury. The mercury is blocked by the piston inside the storage tube to prevent leakage. The outer surface of the piston is slidably connected to the inner wall of the storage tube. The end of the piston away from the mercury is fixedly installed at one end of the telescopic rod. When the temperature is high, the mercury expands and drives the piston and the telescopic rod to the controller. When the telescopic rod in the trigger assembly 308 contacts the controller 309, the controller 309 controls the heater 10 to stop working and stops heating the coal mine. When the temperature in the coal mine is low, the controller 309 does not contact the trigger assembly 308. The controller 309 controls the heater 10 to heat the air passing through the heater 10, which is beneficial to increasing the temperature in the coal mine and avoiding excessive temperature difference between the inside and the outside to affect the health of the workers.
