Miner lamp

Abstract

The invention discloses a miner lamp which comprises a lamp holder component and a power supply box electrically connected with the lamp holder component, wherein the power supply box comprises a box body, a storage battery located in the box body, a charging device and a power generation device partially accommodated in the box body; a step hole is formed in the side wall of the box body; the power generation device comprises an electric generator, a rocking handle rotating shaft and a power generation rocking handle; the electric generator comprises an upper casing and a lower casing which are in plane explosion-proof fit; a through hole is formed in the side wall of the lower casing; a circular bulge communicated with the through hole is formed on the outer wall; one end of the circular bulge abuts against the inner wall of the box body and is communicated with the step hole; a rotating shaft end of the electric generator is accommodated in the circular bulge; the rocking handle rotating shaft penetrates through the step hole, and one end of the rocking handle rotating shaft is connected with a rotating shaft of the electric generator; and the other end of the rocking handle rotating shaft is connected with the power generation rocking handle. The power generation rocking handle is rotated, so that the electric generator generates power, and the storage battery supplies power to the lamp holder component in time; the upper casing, the lower casing and the rotating shaft of the electric generator form a sealed explosion-proof structure, and the circular bulge seals the step hole, so that electric sparks produced in the box body are prevented from floating towards the outside, and the safety of the miner lamp is higher.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a miner's lamp. Background technique [0002] Miner's lamps are generally used in mines and other places with gas and coal dust explosion hazards. It is an essential lighting tool for underground operations. If the miner's lamp fails during the operation of the mine workers, it will bring great potential safety hazards. Especially in the case of accidents such as explosions or mine collapses, the failure of the miner's lamp makes the trapped people unable to save themselves in the dark, and it is difficult to escape, which brings great psychological fear to the trapped people, and even leads to psychological collapse and loss of survival. Faith leads to death. [0003] Traditional miner's lamps are generally powered by batteries. When the battery is exhausted, if the electricity cannot be stored in time, the miner's lamps will fail to illuminate. Especially in the case of a d...
