Problems solved by technology

At present, the lamps and lanterns used in coal mines will display the words "It is strictly forbidden to open the cover with electricity" on the end cover, but as the use time increases, a large amount of dust will be covered on the end cover, and the words "It is strictly forbidden to open the cover with electricity" may be displayed. Cover it, when the staff opens the cover directly without seeing the words of caution, flammable and explosive gas enters and there is a danger of explosion

Abstract

The invention belongs to the technical field of illumination, and in particular discloses an explosion-proof structure of a mine lamp. The explosion-proof structure comprises a junction box and an end cover of the junction box, a driving power supply for driving an illumination lamp to work is arranged in the junction box, a connecting terminal electrically connected with the driving power supply and connected with an external power supply is arranged in the end cover, two mobile dynamic contact switches in normally-open states are arranged at the input end of the driving power supply, and a mechanism capable of being matched with the contact switches to control power-on and power-off when the end cover is opened and closed is arranged on the end cover. Through the explosion-proof structure, the safety of the mine lamp is greatly improved, and various safety accidents caused by misuse of the mine lamp are eliminated.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to an explosion-proof structure of a miner's lamp. Background technique [0002] Safety production is the most important link in coal mines, and a large amount of flammable gas will be released during the coal mining process. Once encountering sparks, etc., it will ignite and explode. The consequences are dire. Therefore, in the harsh underground conditions, the anti-security safety system of lighting fixtures is particularly important. At present, the lamps and lanterns used in coal mines will display the words "It is strictly forbidden to open the cover with electricity" on the end cover, but as the use time increases, a large amount of dust will be covered on the end cover, and the words "It is strictly forbidden to open the cover with electricity" may be displayed. Cover it, and when the staff opens the cover without seeing the notice, there is a danger of explosion if flammabl...
