Coal mine geological water leakage alarm device

Abstract

The invention discloses a coal mine geological water leakage alarm device, and belongs to the technical field of coal mine alarm equipment. The coal mine geological water leakage alarm device comprises a fixing base, an outer flange is fixedly arranged on the edge of the top face of the fixing base, an inner flange is fixedly arranged in the middle of the top face of the fixing base, a plurality of tooth columns are fixedly arranged at the lower end of the inner wall of the outer flange at equal intervals, a gear is arranged between the left inner wall of the outer flange and the left outer wall of the inner flange, a box body is arranged above the front side of the gear, the lower portion of the rear wall of the box body is rotationally connected with a shaft center through a bearing seat, the upper end of the shaft center is coaxially and fixedly connected with a motor, the middle of the shaft center is sleeved with a bevel gear A, rollers are rotationally connected to the two sidesof the box body relative to the positions above the outer flange and the inner flange, the box body is internally hollow to form a cavity, and a swing assembly is arranged in the cavity. According tothe device, water leakage on the top surface of a mine tunnel can be early warned before accumulated water is generated, so that water leakage warning dead angle is effectively reduced, flexibility and practicability of the device are greatly improved, and the effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of coal mine alarm equipment, in particular to a coal mine geological water leakage alarm device. Background technique [0002] When mining underground coal mines, it is necessary to pay attention to the problem of groundwater infiltration and real-time monitoring to prevent problems before they happen. The existing monitoring methods generally use manual inspection, which has a long inspection period and poor monitoring effect. When it is dangerous, it cannot be discovered in time, and the incidence of danger is relatively high. [0003] After searching, the patent with the publication number CN211370497U discloses a coal mine geological water leakage alarm device. The floating conductive plate and the fixed conductive plate structure can realize the alarm when the alarm is energized by the buoyancy rise of the floating ball. By setting the positioning stretching structure, It can realize fixed-point alarm...

AI Technical Summary

Problems solved by technology

[0006] The existing device can timely warn of water leakage, but in the mine tunnel, due to the long length of the mine tunnel, it will be very costly to install the device intermittently and the road section between two adjacent devices There will be omissions, which is not conducive to the full monitoring of the water leakage on the top of the mine. In view of this, we propose a coal mine geological water leakage alarm device
