Explosion-proof motor with high safety performance for coal mine and underground

Abstract

The invention discloses a coal mine and underground high-safety flame-proof motor which comprises a motor body, an inner shell and an outer shell, the motor body is arranged in the inner shell, the outer shell is arranged on the outer side of the inner shell in a sleeving mode, and the inner shell and the outer shell are fixedly connected through two first sealing rings. A first end cover is arranged at one end of the inner shell, a second end cover is arranged at one end of the outer shell, two second sealing rings are arranged between the inner shell and the second end cover, a first anti-explosion mechanism is arranged in the inner shell, and a second anti-explosion mechanism is arranged between the inner shell and the outer shell. According to the explosion-proof motor, the inner shell and the outer shell are arranged, the two end covers on the inner shell and the outer shell are staggered, the situation that sparks are directly leaked from the connecting position of the end covers of the inner shell and the outer shell when the motor body generates the sparks is prevented, the explosion-proof effect of the motor is good by arranging multiple explosion-proof mechanisms, and the safety of the external environment is improved.

Description

technical field [0001] The present invention and the technical field of explosion-proof motors are, in particular, a high-safety-performance explosion-proof motor for coal mines and underground mines. Background technique [0002] The flameproof explosion-proof motor is a motor that works in an explosive environment. The explosive mixture will enter the motor through the gap between the parts of the motor. When sparks or high temperature are generated inside the motor, an explosion will occur. The explosion-proof motor requires that the entire motor casing cannot be destroyed during the explosion process, and the explosion inside the motor cannot detonate the explosive mixture outside the motor. Generally, in order to improve the flameproof capability of the flameproof motor, the shell of the flameproof motor is made relatively thick, and then bolted to the end cover to reduce the gap between the flameproof motor shell and the end cover and improve the flameproof motor. tig...

AI Technical Summary

Problems solved by technology

[0003] The flameproof motor used in underground coal mines is one of the more commonly used ones, but the internal environment of flameproof motors used in underground coal mines is easy to communicate with the external environment, which is easy to cause explosions in the external environment, and the flameproof effect is insufficient and the safety is low.
