Description

Technical Field

[0001] The utility model relates to the field of waterproof alarm equipment, in particular to a mine water prevention and control monitoring device. Background Art

[0002] Coal mines are mines specifically used for mining coal. They are generally located underground, which makes them very susceptible to groundwater infiltration. Once a large amount of groundwater infiltrates into the coal mine, it will cause mining accidents and pose a threat to the personal safety of miners.

[0003] Therefore, when digging coal mines, water prevention and control early warning devices are generally installed in different areas so that when water leaks begin to appear in the mine, they can be discovered in time to better respond or allow miners to escape in time. After searching, the relevant water prevention and control early warning devices mostly use the buoyancy of water to drive the buoyancy parts to move upward. When the buoyancy parts move upward, the preset early warning devices are triggered and the water prevention and control early warning devices send out an alarm signal to remind the staff to evacuate. The alarm signal sent out by the above-mentioned water prevention and control early warning device means that water has been leaking around the early warning device for some time and the water level has reached a certain height. If the leaking area is relatively wide and the leaking water cannot gather quickly, it will affect the warning effect.

[0004] Therefore, how to provide a mine water prevention and control monitoring device to achieve rapid monitoring of water leakage has become a difficult problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] The utility model aims to provide a mine water prevention and control monitoring device to solve the problem that the existing water prevention and control early warning device cannot monitor in time.

[0038] Specifically, through holes 31 are symmetrically arranged at the four corners of the first protective plate 3, a fixing groove 32 is arranged on one side plate surface of the first protective plate 3, the through holes 31 are sleeved on the rod body of the alarm fixing frame 1, and the bottom surface of the first protective plate 3 and the top surface of the slide cylinder 21 are abutted together; the structure of the second protective plate 5 is the same as that of the first protective plate 3.

[0039] Specifically, the filter cartridge 6 is fixed between the first protective plate 3 and the second protective plate 5 through a fixing groove 32 .
