[0040] The beneficial effects of the above preferred scheme are that the horizontal sliding mechanism is beneficial to slide along the channel steel outer frame, so as to adjust the shielding area of the ventilation adjusting port, and then realize the adjustment of the ventilation air volume.

[0041] Preferably, as shown in Figure 3 The horizontal sliding mechanism 3 comprises an angle steel outer frame 31, a steel plate 32, a plurality of angle steel reinforcing struts 33 and a handle 34. The angle steel outer frame 31 is slidingly installed in the channel steel outer frame 21. The steel plate 32 is fixedly arranged in the angle steel outer frame 31. The angle steel reinforcing struts 33 are arranged in the angle steel outer frame 31, and both ends thereof are fixedly connected with the inner wall of the angle steel outer frame 31. The handle 34 is fixedly arranged on the angle steel reinforcing struts 33 or the steel plate 32.

[0042] It should be noted that in the embodiment, the steel plate 32 covers the internal through hole of the angle steel outer frame 31, so that the steel plate 32 and the angle steel outer frame 31 are connected to form an airtight whole.

[0043] The beneficial effects of the above preferred scheme are that the steel plate is fixedly arranged in the angle steel outer frame, which is beneficial to shield the ventilation adjusting port and avoid inaccurate adjustment of the ventilation air volume due to air leakage. The plurality of angle steel reinforcing struts are beneficial to enhance the strength of the angle steel outer frame. The handle is beneficial to drive the horizontal sliding mechanism to slide in the channel steel outer frame.

[0044] Preferably, the top end and the bottom end of the angle steel outer frame 31 are fixed with sliding blocks, and the sliding blocks at the top end and the bottom end of the angle steel outer frame 31 are one-to-one slidingly connected with the sliding rails at the top end and the bottom end of the inner side of the channel steel outer frame 21.

[0045] It should be noted that in the embodiment, the horizontal sliding mechanism 3 horizontally slides in the channel steel outer frame 21, that is, when not subjected to external force, the horizontal sliding mechanism 3 can stop at any position of the sliding rail of the inner side of the channel steel outer frame 21.

[0046] The beneficial effect of the above preferred scheme is that the cooperation of the sliding block and the sliding rail is conducive to the horizontal sliding of the horizontal sliding mechanism in the frame mechanism under the external push-pull force, thereby realizing the adjustment of the ventilation air volume.

[0047] Preferably, as shown in the figure, the dynamic buffering mechanism 4 comprises a buffering plate 41, an anchoring plate 42 and a plurality of anchoring members 43, the buffering plate 41 is of flexible material, the top end of the buffering plate 41 is fixedly connected with the anchoring plate 42 through the plurality of spaced anchoring members 43, the anchoring plate 42 is fixedly arranged on the brick wall 1 or the frame mechanism 2 through the anchoring members 43, and the buffering plate 41 covers or uncovers the dynamic buffering port 12. Figures 4 to 6 The beneficial effect of the above preferred scheme is that the cooperation of the sliding block and the sliding rail is conducive to the horizontal sliding of the horizontal sliding mechanism in the frame mechanism under the external push-pull force, thereby realizing the adjustment of the ventilation air volume.

[0048] It should be noted that in the embodiment, the anchoring plate 42 is fixedly arranged on the brick wall 1 through the anchoring members 43, and in other preferred embodiments, the anchoring plate 42 is fixedly arranged on the top end of the channel steel outer frame 21 through the anchoring members 43. After the pressure relief is completed, the buffering plate 41 recovers the covering of the dynamic buffering port 12 under the action of its own gravity, which is not a complete sealing, and a small amount of air will flow out of the dynamic buffering port 12 during non-blasting operation, but it is much smaller than the ventilation air volume of the ventilation adjusting port 13 during non-blasting operation, so the air leakage from the dynamic buffering port 12 can be ignored when adjusting the ventilation air volume during non-blasting operation.

[0049] The beneficial effect of the above preferred scheme is that the buffering plate of flexible material is conducive to being lifted along the connection between the anchoring plate and the buffering plate under the impact wave generated by blasting, opening the dynamic buffering port, accelerating the pressure relief, and recovering the covering of the dynamic buffering port after the pressure relief is completed, thereby being conducive to realizing the adjustment of the ventilation air volume through the horizontal sliding mechanism.

[0050] Preferably, the buffering plate 41 is of rubber material.

[0051] The beneficial effect of the above preferred scheme is that the rubber material is conducive to making the buffering plate have flexible characteristics, being bent and lifted under the impact wave generated by blasting, and also having a certain gravity and resilience, which is conducive to recovering the original state of covering the dynamic buffering port after the pressure relief is completed.

[0052] Preferably, the brick wall 1 is fixedly arranged in the underground mine passage.

[0053] The beneficial effect of the above preferred scheme is that it is conducive to realizing the air volume adjustment in the underground mine passage through the horizontal sliding mechanism, which is conducive to realizing the accurate adjustment of the air volume.

[0054] The working process of this invention is described below: like Figures 1 to 6 As shown, during non-blasting operations, the buffer plate 41 hangs down naturally under its own weight, covering the dynamic buffer opening 12. At this time, the externally applied pushing or pulling force is transmitted to the horizontal sliding mechanism 3 through the handle 34, causing the horizontal sliding mechanism 3 to push and pull along the outer frame 21 of the channel steel. During this process, the horizontal sliding mechanism 3 blocks different areas of the ventilation regulating opening 13, thereby changing the air volume through the ventilation regulating opening 13 and thus achieving the adjustment of the ventilation air volume.

[0055] During blasting operations, the pre-adjusted ventilation volume is maintained, meaning the horizontal sliding mechanism 3 is not displaced on the channel steel frame 21, and the obstruction area of ​​the horizontal sliding mechanism 3 on the ventilation regulating port 13 is maintained. Under the shock wave generated by the blast, on the one hand, the impact airflow is discharged from the ventilation regulating port 13, which was originally partially obstructed by the horizontal sliding mechanism 3; on the other hand, the impact airflow lifts the buffer plate 41 along its connection point with the anchor plate 42, exposing the dynamic buffer port 12. At this time, the impact airflow will be discharged from the dynamic buffer port 12. The dynamic buffer port 12, in conjunction with the ventilation regulating port 13, accelerates the depressurization and avoids a large impact on the brick wall 1. After the depressurization is completed, the buffer plate 41 naturally droops under its own weight, covering the dynamic buffer port 12 again. At this time, it is not necessary to readjust the obstruction area of ​​the horizontal sliding mechanism 3 on the ventilation regulating port 13 again to restore the ventilation volume during non-blasting operations.

[0056] This embodiment has the following advantages: (1) Strong impact resistance: The dynamic buffer mechanism 4 can quickly respond to blasting impact, protect the main structure of the windshield, and extend the service life of the brick wall 1; (2) Adaptive adjustment: Since the wind window itself needs to pass through a certain amount of air, the slight air leakage of the dynamic buffer mechanism 4 under the wind pressure of non-blasting operation does not affect the function of the wind window. It is only necessary to move the horizontal sliding mechanism 3 left and right in the frame mechanism 2 to adjust the overall air volume of the wind window (including the air volume of the horizontal sliding mechanism 3 and the air volume of the dynamic buffer port 12). At the moment of blasting, the buffer plate 41 is lifted under the impact of the detonation wave, and the detonation wave passes through the peak quickly. After the blasting is completed, the buffer plate 41 returns to its original position. The entire blasting process does not require manual operation. After the detonation wave passes through in an instant, the wind window immediately returns to its original state to ensure stable ventilation in the well. (3) Easy to operate: The air volume can be adjusted by the horizontal sliding mechanism 3 to adapt to different operation needs; (4) Low cost, easy to manufacture and install.
