Impact-wave-type-resistant coal mine protection device capable of efficiently relieving pressure

Abstract

The invention discloses an impact-wave-type-resistant coal mine protection device capable of efficiently relieving pressure. The impact-wave-type-resistant coal mine protection device comprises a mine exhaust outlet, a sleeve cover, a circular ring plate and a longitudinal threaded rod, wherein the mine exhaust outlet is formed in the bottom surface of a mining area, the top of the mine exhaust outlet is connected with an explosion-proof cover used for protection in a nested mode, and filtering and purifying openings used for ventilating and filtering harmful substances are formed in the explosion-proof cover at equal angles; the sleeve cover is connected to the outer side of the top of the explosion-proof cover in a sleeving and attached mode, a vent hole used for relieving pressure is correspondingly formed in the sleeve cover, and the bottom of the sleeve cover is connected into a space formed by a mounting groove; the circular ring plate is movably connected to the bottom of the inner side of the mine exhaust outlet; and the longitudinal threaded rod is connected to the bottom of the explosion-proof cover through a symmetric shaft, and the longitudinal threaded rod is connected with a transverse threaded rod through a conical tooth connecting piece. According to the impact-wave-type-resistant coal mine protection device capable of efficiently relieving pressure, rapid pressure relief can be carried out, air and impurities can be filtered, the filtered impurities can be cleaned, and meanwhile, automatic reset can be carried out after cleaning is completed.

Description

technical field [0001] The invention relates to the technical field of coal mine protection devices, in particular to an anti-shock wave type coal mine protection device for high-efficiency pressure relief. Background technique [0002] When excavating the coal mine in the mine, there will be some explosive materials and materials in the mine. In order to prevent accidents, an efficient pressure relief anti-shock wave coal mine protection device will be installed at the vent of the mine. However, now Some high-efficiency pressure relief anti-shock wave coal mine protection devices have the following problems: [0003] Notification number CN212716722U discloses a safety explosion-proof device for coal mine ventilation, which relies on wind power to drive the device, which is energy-saving and environmentally friendly, and can filter the air. However, it is inconvenient to clean up filtered sundries during use, and it is inconvenient to automatically reset after cleaning. ...
