Description

Technical Field

[0001] The utility model relates to the technical field of mine production safety monitoring instruments, in particular to an infrared emitting device for mines. Background Art

[0002] During coal mining, the hydraulic support electro-hydraulic control system typically needs to know the position and orientation of the shearer to facilitate fully mechanized and automated coal mining. This is achieved by installing an infrared transmitter on the shearer and an infrared receiver on the hydraulic support. The infrared transmitter housing contains an infrared emitter, with an opening at one end and a glass plate positioned above the opening for infrared transmission. A controller controls the infrared emitter to generate a regular waveform signal. The glass plate faces the infrared receiver on the hydraulic support, which receives the infrared light emitted by the emitter. As the shearer advances to cut coal, the infrared light emitted by the infrared transmitter is continuously received by the infrared receiver on the opposite hydraulic support. This allows the electro-hydraulic control system of the hydraulic support on the working face to constantly monitor the position and orientation of the shearer, enabling efficient and automated coal mining.

[0003] However, the working conditions of the coal mining machine are poor. Mine water will be generated during the coal mining process. The water will drip onto the infrared emitting device and flow into the box along the gap between the glass plate and the box, causing a short circuit in the circuit board and corroding the internal components, thus affecting the service life.
