The detection alarm 8 is connected to the upper front side of the sliding plate 71. The detection alarm 8 is electrically connected to the seismic wave detector 7.

When the seismic wave detector 7 detects abnormal seismic activity, the detection alarm 8 sounds an alarm to prompt the construction personnel in the mine to evacuate, and then the installation frame 9 is installed. The alarm 10 transmits a signal to the monitoring personnel to give an alarm prompt, so that an alarm prompt can be issued when abnormal seismic activity is detected, which is convenient for timely evacuation of construction personnel and ensures the safety of construction personnel. When the ventilation volume of the mine needs to be adjusted, the electric push rod 15 can be started to drive the guide frame 16 to move. Through the cooperation of the guide frame 16 and the rotating ring 14, the rotating ring 14 is driven to rotate, so that the rotating guide rail 13 rotates, and the slide bar 12 is driven to move on the rotating guide rail 13. Under the action of the sliding cooperation between the slide bar 12 and the space cam 11, the space cam 11 is driven to rotate, so that the fan blades 6 rotate, thereby increasing or decreasing the ventilation volume, so that the angle of the fan blades 6 can be quickly adjusted according to different ventilation needs, which is convenient for controlling the size of the ventilation volume and improving the flexibility of using the device. When the ordinary motor 5 and the fan blades 6 need to be repaired, the rotating plate 41 can be rotated to open for observation and maintenance.

[0043] like Figure 1 , Figure 7 and Figure 8 As shown, it also includes a servo motor 17, an outer gear ring 18, a gear 19, a screw 20, an annular brush plate 21, a water storage frame 22 and a hose 23.

After the inspection is completed, the protective frame 27 can be loosened, the torsion spring 30 can be restored, and the protective frame 27 can be driven to rotate and reset, and then the clamping rod 28 can be loosened, the telescopic spring 29 can be restored, and the clamping rod 28 can be driven to move and reset, so that the clamping rod 28 is engaged with the protective frame 27, so that the seismic wave detector 7 can be protected, the seismic wave detector 7 can be prevented from being physically damaged, and the life of the equipment can be extended.

[0049] like Fig.13As shown, it also includes a mounting frame 31, a fan 32 and an air outlet pipe 33.

[0050] When the mine environment is relatively humid, the fan 32 on the mounting frame 31 can be started so that wind blows toward the seismic wave detector 7 and exhausts air through the exhaust pipe 33, thereby drying the seismic wave detector 7, avoiding a humid environment, reducing the impact of moisture on the internal electronic components of the seismic wave detector 7, and improving the accuracy of the measurement.

[0051] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention.
