Abstract
The utility model relates to an intrinsic safety miner lamp, and belongs to the technical field of coal mine safety devices. According to the technical scheme, the intrinsic safety miner lamp comprises a lamp base (1), a cable (2) and a storage battery (3), the lamp base (1) is connected with the storage battery (3) through the cable (2), and the output end of the storage battery (3) is provided with a miner lamp intrinsic safety power source comprehensive protector (4). The intrinsic safety miner lamp has the advantages that the miner lamp intrinsic safety power source comprehensive protector is arranged to be connected with the storage battery to form an intrinsic safety power source component, therefore, the purpose of intrinsic safety is achieved and safety production of the coal mine industry is effectively guaranteed.
Description
Technical field
The utility model relates to a kind of intrinsic safety mine lamp, belongs to safety of coal mines device technique field.
Background technology
Mine lamp, as explosion-proof lamp, due to the limitation of its environment for use having a large capacity and a wide range and explosion-proof condition, founded the state all the time because its high-risk feature is subject to strict control from 1949.According to coal mining accident analysis of data: wood coombe colliery, Guizhou, on September 27th, 2000, because mine lamp loses the quick-fried gas accident that causes, dead 162 people, injured 37 people; This ore deposit on February 24th, 2003, again because mine lamp loses the quick-fried gas accident that causes, dead 39 people, injured 18 people.According to incompletely statistics, from founding the state, because mine lamp loses the quick-fried gas accident causing, account for 15% of total accident.Give a lesson to very painful! " mine lamp must be equipped with reliable short-circuit protection in < < safety regulations in coal mine > > requirement.Highly gassy mine should be equipped with short-circuit protector." mine lamp that uses of the current colliery of China is all explosion-proof particularity, remained potential safety hazard.
Utility model content
The utility model object is to provide a kind of intrinsic safety mine lamp, by mine lamp intrinsic safety electric source comprehensive protection device is set, is connected to form intrinsic safety electric source assembly with battery, reaches the object of essential safety, solves the problems referred to above that exist in background technology.
The technical solution of the utility model is: a kind of intrinsic safety mine lamp, comprise lamp holder, cable and battery, and described lamp holder and battery are connected to each other by cable, and the output of battery is provided with mine lamp intrinsic safety electric source comprehensive protection device.
