Nitrogen-charging positive-pressure explosion-proof system of underground wireless charging safety house and working method of nitrogen-charging positive-pressure explosion-proof system

The invention belongs to the technical field of coal mine underground inspection robot application, and particularly discloses a nitrogen-charging positive-pressure explosion-proof system of an underground wireless charging safety house. The nitrogen-charging positive-pressure explosion-proof system comprises a nitrogen tank, a nitrogen guide pipe, a main nitrogen guide pipe, a sucking pump, a branch nitrogen guide pipe, a first nitrogen conveying pipe, a second nitrogen conveying pipe and the like, the first nitrogen conveying pipe is connected with the outer wall of a control cabin of the underground wireless charging safety house, and the second nitrogen conveying pipe is connected with the outer wall of a charging cabin of the underground wireless charging safety house. The nitrogen-charging positive-pressure explosion-proof system has the beneficial effects that when the inspection robot is charged in the underground wireless charging safety room, flammable and explosive gas does not enter the undergroun
