Dust-proof and explosion-proof type LED illuminating lamp for underground engineering

Abstract

The invention discloses a dust-proof and explosion-proof type LED illuminating lamp for underground engineering. The dust-proof and explosion-proof type LED illuminating lamp comprises a lamp shell, alamp body is fixedly connected to the lower end of the lamp shell, a liquid storage cavity is formed in the lower end of the lamp shell, a sliding plate is connected to the inner wall of the liquid storage cavity in a sealed and sliding mode, and the side wall of the sliding plate is elastically connected with the inner wall of the liquid storage cavity through a memory spring; a circular cavityis formed in the position, located above the liquid storage cavity, of the lamp body, a plurality of impellers are rotationally connected to the inner wall of the circular cavity through a rotating shaft, and the inner wall, away from the memory spring, of the liquid storage cavity is connected with the inner wall of the circular cavity through a liquid inlet pipe. Through the liquid storage cavity and the memory spring, heat on the lamp body can be absorbed, the lamp body can be effectively cooled, meanwhile, after induced current is generated on the spiral coil, a large number of negative charges exist on the dust collection cover, then dust in underground engineering is adsorbed, the dust can be effectively prevented from drifting away freely to endanger health of workers.

Description

technical field [0001] The invention relates to the technical field of LED lighting lamps, in particular to a dust-proof and explosion-proof LED lighting lamp for underground engineering. Background technique [0002] Among many projects, underground projects are relatively more dangerous because of the stability of the underground structure and the brightness of the environment. At present, the underground projects are artificially using LED lighting to improve the illumination. [0003] Because there is a lot of dust in the underground project, more dust will accumulate on the surface of the LED lighting lamp when it is used, which will affect the illumination of the lamp body after long-term use, and the interior of the LED lighting will accumulate More heat, due to the poor air flow in the underground project, the heat on the LED lighting cannot be dissipated in time, and the dust covering the LED lighting further inhibits the heat dissipation in the LED lighting Dissip...

Problems solved by technology

[0003] Because there is a lot of dust in the underground project, more dust will accumulate on the surface of the LED lighting lamp when it is used, which will affect the illumination of the lamp body after long-term use, and the interior of the LED lighting will accumulate More heat, due to the poor air flow in the underground project, the heat on the LED lighting cannot be dissipated in time, and the dust covering the LED lighting further inhibits the heat dissipation in the LED lighting Emission, making LED lighting easy to explode when the temperature rises, affecting its service life
