Explosion-proof wiring device for compressor head of cooling unit in mine

Abstract

The invention discloses an explosion-proof wiring device for a compressor head of a cooling unit in a mine, comprising an explosion-proof box and wiring partition plates, wherein the wiring partition plates are used for fixedly connecting the explosion-proof box to the compressor head, the wiring partition plates are in sealed and fixed fit with the wiring partition plates on the compressor head, and the explosion-proof box is in sealed and fixedly fit with the wiring partition plates by an explosion plane; and the wiring partition plates are respectively provided with a power-line terminal and a motor overtemperature protection output signal terminal, and two ends of the power-line terminal respectively stretch into the explosion-proof box and the compressor head. The connection device can carry out explosion-proof reformation on partial connection of the compressor head under the condition that the structure and the size of the existing semienclosed screw-typed compressor head without an explosion-proof function are not changed, thereby meeting the use requirements in the coal mine, simply and effectively improving the performances of underground cooling equipment in the coal mine, not increasing the development and manufacturing cost of the equipment and being suitable for propularization and application.

Description

Technical field [0001] The invention relates to a mine explosion-proof equipment, in particular to an explosion-proof wiring device for the compressor head of a mine cooling unit. Background technique [0002] As the mining depth of mines increases, more and more mines suffer from heat damage due to heat sources such as heat dissipation from high-temperature surrounding rock, self-compression heat of air, heat dissipation from mechanical equipment, and oxidation heat. Thermal damage is one of the factors restricting safe production in mines, which not only endangers the health of miners, but also reduces labor productivity and affects safe production and economic benefits. [0003] Mine thermal hazards have become an urgent problem for more and more mines, and from the perspective of scientific development, effective management of mine thermal hazards has important strategic significance for my country's future mining of mineral resources in a greater depth. [0004] The use of min...

Problems solved by technology

[0006] Since the semi-hermetic compressor has many advantages above, it is suitable for application in coal mine refrigeration and cooling equipment. However, the semi-hermetic compressor heads currently on the market cannot be used in coal mine underground explosive gas environments. The main reason is that the wiring part of the machine head Can not meet the explosion-proof requirements
