Mine emergency physical power generation device

Abstract

The invention discloses a mining emergency physical power generation device. The mining emergency physical power generation device comprises a manipulator, a transmission part, an electric generator and an electric storage device; the manipulator comprises a frame and a driving wheel which is in pivoted connection with the frame; the electric generator comprises a rotating casing and a fixed shaft which is used for fixedly connecting the frame and arranged in the center of the rotating casing; the electric generator is a brushless electric generator; the driving wheel is connected with the rotating casing through the transmission part; the rotating casing is provided with the explosive-proof joint surface; the fixed shaft is provided with the cable outlet which is used for drawing cables out of the rotating casing; the cables are electrically connected with the electric storage device. Users consume energy through the manipulator, the electric generator is driven by produced mechanical energy through the transmission part to generate electricity, and accordingly the electric storage device can be charged or directly used; the fixed shaft is utilized as a stator, the rotating casing is utilized as a rotor, and accordingly the electric generator is simple and compact in structure and suitable for a mine; the possibility of production of electric arcs and electric sparks can be greatly reduced due to the brushless electric generator; the explosive-proof joint surface can prevent an internal explosion from spreading towards the surrounding explosive gas of the rotating casing and accordingly the explosion-proof performance is enhanced.

Description

technical field [0001] The invention relates to a physical power generation device, in particular to a physical power generation device suitable for emergency use in coal mine underground refuge cabins and refuge chambers. Background technique [0002] Coal mine emergency avoidance system refers to an organic whole composed of facilities, equipment, and measures that provide life support for people in distress to avoid danger in the event of an emergency underground in a coal mine. The construction of the emergency avoidance system includes providing self-rescue devices for those entering the well, constructing underground emergency avoidance facilities, rationally setting disaster avoidance routes, and scientifically formulating emergency plans, etc. When accidents such as gas or coal seam outburst, explosion, fire, roof fall and other accidents occur underground in coal mines, toxic and harmful gases may diffuse in the underground tunnel, and tunnel blockage may occur.

AI Technical Summary

Problems solved by technology

When a disaster occurs in a coal mine, the power supply of the emergency avoidance system itself is exhausted or the power fails, and the power supply of the entire emergency avoidance system will stop, which may cause serious consequences
