Coal mine underground permeable early warning device

Abstract

The invention discloses a coal mine underground permeable early warning device, and belongs to the technical field of coal mine safety equipment. The coal mine underground permeable early warning device comprises at least one non-contact infrared temperature measuring sensor and a single chip microcomputer connected with the non-contact infrared temperature measuring sensor, wherein an output port of the single chip microcomputer is connected with a warning device, the non-contact infrared temperature measuring sensor and the single chip microcomputer connected with the non-contact infrared temperature measuring sensor are preferably thermal infrared imagers, a temperature lower limit warning output interface of each thermal infrared imager is connected with the warning device, the warning device is an electric bell, the temperature lower limit warning output interface of each thermal infrared imager is connected with the electric bell of a cascading alternating current 127V power supply through a relay, the thermal infrared imagers are positioned in a case, and the case is an explosion-proof case. The coal mine underground permeable early warning device has the characteristics that the work is reliable, the use is safe, and the like. The coal mine underground permeable early warning device can effectively realize the advanced early warning on the conditions of coal mine underground permeation for guaranteeing the coal mine production and the personnel safety.

Description

technical field [0001] The invention relates to the technical field of coal mine safety equipment. Background technique [0002] For coal mine production, "water seepage" is a very serious accident, even more serious than the consequences of gas explosion, which seriously threatens the safe production of coal mines. If you do not pay attention to a "water seepage" accident, it will cause huge personal injury and property loss. Now, the possible "water penetration" is judged manually based on experience, and cannot be monitored 24 hours a day. In addition, it is easy for personnel to make mistakes in judgment, so it is imperative to develop a set of underground water permeable early warning devices for coal mines. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an underground water permeable early warning device for coal mines, which has the characteristics of reliable operation and safe use. It can effectively...
