Self-restoration flying wing type inclined shaft explosion door

Abstract

The invention provides a self-restoration flying wing type inclined shaft explosion door which comprises elastic force glue, skew plates, jack sockets, contact chips, loudspeakers, a protective tank,protective seats, damping springs, latex mattresses and damping plates. The elastic force glue is installed in the inclined shaft body, wherein the skew plates are assembled on the inner side of the elastic force glue, and the jack sockets are formed in the inner side of the skew plates. The contact chips are fixed to the bottom of the skew plates, and the loudspeakers are arranged on the upper end surface of the inclined shaft body. The self-restoration flying wing type inclined shaft explosion door solves the problem that alarm measures of original explosion doors are lacking. The protectivetank is assembled on the rear side of the inclined shaft body. The protective seats are installed on the upper end surface of erasure packing, wherein the damping springs are installed on the upper end surfaces of the protective seats. The latex mattresses are installed on the upper end surface of protective plates, and the damping plates are fixed to the upper end surfaces of the latex mattresses. The self-restoration flying wing type inclined shaft explosion door solves the problem that the protective measures of electric appliances are lacking when mounting of the original explosion doors.The self-restoration flying wing type inclined shaft explosion door has reasonable structure, good protective effect, comprehensive functions and convenient and fast self-restoration.

Description

technical field [0001] The invention relates to a self-resetting fin type inclined shaft explosion-proof door, belonging to the technical field of underground ventilation systems in coal mines. Background technique [0002] The explosion-proof door of the coal mine return air shaft is an important component of the underground coal mine ventilation system. At present, all coal mines that meet the standards in my country are required to install explosion-proof doors and covers in order to protect the main fan from being damaged when the explosion shock wave arrives. During normal ventilation, it is used to isolate the underground air flow from the ground atmosphere to prevent short circuit of the air flow and ensure the normal operation of the ventilation system; when a gas or coal dust explosion occurs in the well, the explosion-proof door will be swept away by the explosive air flow, and the shock wave will be directly discharged to the The atmosphere outside the ground can...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the reset of the existing explosion-proof door is not convenient enough, and it is inconvenient to automatically reset after the explosion-proof door is opened. The existing explosion-proof door does not have enough protection measures for electrical appliances. When an explosion occurs, the huge shock wave is easy to Cause vibration damage to the motor and reducer. At the same time, the existing explosion-proof door is inconvenient to give an alarm when the explosion-proof door cannot be closed. Now there is an urgent need for a self-resetting fin-type inclined shaft explosion-proof door to solve the above problems
