Explosive-proof water bag with automatic water injection

Abstract

The invention relates to the technical field of explosive-proof water bags, in particular to an explosive-proof water bag with automatic water injection. The explosive-proof water bag comprises bottomplates, supporting frames are fixedly connected to the upper sides of the bottom plates, a top plate is shared by and fixedly connected to the top ends of the two supporting frames, two height increase and decrease devices are symmetrically and fixedly connected to the lower sides of the bottom plates, a water injection plate is shared by and fixedly connected to the top ends of the two height increase and decrease devices, and multiple water bags are connected to the lower side of the water injection plate through hooks; a cavity is formed in the water injection plate, and a water outlet channel is formed in the lower side of the cavity. The explosive-proof water bag has the following advantages that the other ends of movable plates extrude triangular inclined blocks so that the triangular inclined block can move downwards, accordingly, vertical pillars drive plugging balls to overcome pull force of springs to move downwards, water in the cavity will flow downwards into the water bags through the water outlet channel, in this way, the function of water injection is realized without manual operation, the efficiency of water injection is effectively improved, and the explosive-proof water bag has application and popularization value.

Description

technical field [0001] The invention relates to the technical field of explosion-proof water bags, in particular to an automatic water injection type explosion-proof water bag. Background technique [0002] The explosion-proof water bag is an installation container used in coal mines. The water bag shed formed according to the technical requirements of the installation can effectively isolate the spread of gas and coal dust explosions and reduce the losses caused by disasters. The material for making water bags has Flame retardant, anti-static and other safety properties. [0003] Generally, the method of adding water to the explosion-proof water bag is to use the water supply pipe and the water valve together, add water to the explosion-proof water bag, and change the water, but this method cannot accurately judge the water level. If the explosion-proof water bag cannot be filled in time The safe water level will bring safety hazards to safe production; on the contrary, if...

[0003] Generally, the method of adding water to the explosion-proof water bag is to use the water supply pipe and the water valve together, add water to the explosion-proof water bag, and change the water, but this method cannot accurately judge the water level. If the explosion-proof water bag cannot be filled in time The safe water level will bring safety hazards to safe production; on the contrary, if the water in the explosion-proof water bag is overfilled, it is easy to cause the water bag to drop accidents, and the overflowing water will also affect the underground working environment
