[0024] Specifically, in use, the device is connected to the mine and the outside world, then the motor 6 is started to drive the reciprocating screw rod 8 to rotate, so that the sliding sleeve 7 moves up and down, and the moving ring 10 moves up and down, when the moving ring 10 moves downward, the inclined surface connecting block 14 contacts the double-inclined surface telescopic block 16, because the force generated by the strong spring 15 is greater than the force generated by the spring 13, and the contact surfaces of the inclined surface connecting block 14 and the double-inclined surface telescopic block 16 are both inclined surfaces, so the inclined surface connecting block 14 moves into the spring groove, and the valve seat 9 cannot enter the spring groove, so the valve seat 9 rotates to drive the one-way valve diaphragm 17 to move, thereby opening the one-way valve diaphragm 17, so that the air in the mine enters the ventilation pipe 1, when the moving ring 10 moves to the bottom end, because there is no air entering the ventilation pipe 1 through the one-way valve diaphragm 17, the one-way valve diaphragm 17 is automatically closed, when the moving ring 10 moves upward, because the air in the ventilation pipe 1 cannot pass through the one-way valve diaphragm 17, it is discharged from the ventilation pipe 1 through the top side of the ventilation pipe 1, achieving the effect of quickly opening the one-way valve diaphragm 17, so that the one-way valve diaphragm 17 can be quickly opened by the inclined surface connecting block 14 when the moving ring 10 moves downward, thereby improving the ventilation efficiency of the device.
[0025] Referring to Figure 1 , Figure 2 and Figure 4The left end of the top side of the connecting pipe 2 is fixedly connected with a mounting rack 5, the right side of the mounting rack 5 is provided with a motor 6, the driving end of the motor 6 is fixedly connected with the top side of a reciprocating screw rod 8, the outer wall of a scraping ring 11 abuts against the inner wall of the ventilation pipe 1, and the collecting assembly comprises a collecting ring 4, the top side right end of the collecting ring 4 is connected with the bottom side right end of the ventilation pipe 1 through a torsion spring 3, the top side of the collecting ring 4 is fixedly connected with a blocking ring 12, the top side of the collecting ring 4 abuts against the bottom side of the ventilation pipe 1, and the blocking ring 12 is located in the interior of the ventilation pipe 1.
[0026] Specifically, when the moving ring 10 moves up and down, the scraping ring 11 is simultaneously driven to move up and down, and since the outer wall of the scraping ring 11 abuts against the inner wall of the ventilation pipe 1, the inner wall of the ventilation pipe 1 is cleaned when the scraping ring 11 moves up and down, and the impurities and dirt cleaned fall to the top side of the collecting ring 4, which is blocked by the blocking ring 12, so as to prevent the impurities and dirt from falling through the air inlet, after the device is used for a long time, the torsion spring 3 is rotated to open the collecting ring 4 and the collected impurities and dirt are treated, after the treatment is completed, the torsion spring 3 automatically rebounds to drive the collecting ring 4 to reset, so that the collecting ring 4 can work again, and the effect that the inner wall of the ventilation pipe 1 is cleaned and the dirt is collected is achieved, so that the device can be prevented from being blocked in the interior of the ventilation pipe 1 after being used for a long time, and the ventilation efficiency and service life of the device are improved.
[0027] Working principle: in use, the device is connected with the outside world, and then the motor 6 is started to drive the reciprocating screw rod 8 to rotate, so that the sliding sleeve 7 moves up and down, and the moving ring 10 moves up and down, when the moving ring 10 moves downward, the inclined surface connecting block 14 will contact with the double inclined surface expansion block 16, because the force generated by the strong spring 15 is greater than the force generated by the spring 13, and the contact surface of the inclined surface connecting block 14 and the double inclined surface expansion block 16 is inclined, so the inclined surface connecting block 14 will move and enter the spring groove, and the valve seat 9 cannot enter the spring groove, so the valve seat 9 will rotate, thereby driving the one-way valve diaphragm 17 to move, thereby opening the one-way valve diaphragm 17, so that the air in the mine enters the inside of the ventilation pipe 1, after the moving ring 10 moves to the bottom, because there is no air entering the inside of the ventilation pipe 1 through the one-way valve diaphragm 17, so the one-way valve diaphragm 17 will be automatically closed, when the moving ring 10 moves upward, because the air in the ventilation pipe 1 cannot pass through the one-way valve diaphragm 17, so it will be discharged from the inside of the ventilation pipe 1 along with the movement of the moving ring 10, at the same time, when the moving ring 10 moves up and down, the scraping ring 11 will move up and down, and because the outer wall of the scraping ring 11 abuts against the inner wall of the ventilation pipe 1, so when the scraping ring 11 moves up and down, it will clean the inner wall of the ventilation pipe 1, and the collected impurities and dirt will fall to the top of the collecting ring 4, and the blocking ring 12 will block it to prevent it from falling through the air inlet, after the device is used for a long time, the torsional spring 3 can be rotated to open the collecting ring 4 and treat the collected impurities and dirt, after treatment, the torsional spring 3 will automatically rebound to reset the collecting ring 4, so that the collecting ring 4 can work again.
