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 early warning equipment. The coal mine geological water leakage alarm device comprisesan alarm box, a fixing rod is rotatably connected to the middle of the inner wall of the right side of a control box through a hinge pin, a circular floating foam is arranged in the middle in a waterseepage monitoring fixing pin, a motor is fixed to the left side in the alarm box through screws, a circumferential end of a circular shaft penetrates through the alarm box to extend to the outside and is fixedly provided with an alarm lamp, a vibration bell is fixed to the left side of the upper portion of the alarm box through a fixing base, and the outer wall of the circumference of a limitingcolumn B is sleeved with a vibration plate. According to the coal mine geological water leakage alarm device, through close fit of structures, when a situation occurs, alarm is conducted through the lamp and multi-direction monitoring is conducted through the vibration bell, the alarm can be transmitted to a farther distance through vibration early warning of sound, even if a miner does not noticethe early warning of the alarm lamp during working, the situation that dangers cannot be found in time and the danger occurrence rate is relatively high can be avoided through the early warning of the vibration bell, and the monitoring effect is improved.

Description

technical field [0001] The invention relates to the technical field of early warning equipment, and more specifically, relates to a coal mine geological water leakage alarm device. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the distance to the surface is very close, it is generally chosen to directly strip the surface soil layer to excavate coal. This is an open-pit coal mine, and most of the coal mines in my country belong to underground coal mines; when mining underground coal mines, it is necessary to pay attention to the problem of underground mine water penetration , real-time monitoring is needed to prevent problems before they happen. The existing detection methods generally use manual inspection, the inspection period is long, and the monitoring effect is not good. When danger occurs, it cannot be found in tim...

[0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the distance to the surface is very close, it is generally chosen to directly strip the surface soil layer to excavate coal. This is an open-pit coal mine, and most of the coal mines in my country belong to underground coal mines; when mining underground coal mines, it is necessary to pay attention to the problem of underground mine water penetration , real-time monitoring is needed to prevent problems before they happen. The existing detection methods generally use manual inspection, the inspection period is long, and the monitoring effect is not good. When danger occurs, it cannot be found in time, and the incidence of danger is high.

[0003] The document of prior art publication number CN208870642U provides a kind of coal mine underground prevention and control water early warning device, and this device can adjust the height of warning water level through the design of alarm lamp and limit block, but still has the following problems: 1) the warning of this device The effect is weak and is easily ignored by users; 2) The warning range of the device is limited, and it can only warn the operators who are close to the installation position of the device, but when the operators are far away from the device, they cannot provide warnings Function; 3) With the deepening and advancement of mine operations, it is necessary to install multiple devices to cover the warning area, which is costly and poor in practicability
