Description

Technical Field

[0001] The invention relates to the technical field of mining safety equipment, and in particular to an automatic water adding device for a mine explosion-proof water shed and an automatic water adding method thereof. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people usually choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people usually choose to directly strip the surface soil layer to mine coal. This is an open-pit coal mine. During mining operations, it is particularly important to take explosion-proof measures, and explosion-proof water sheds play a good role in explosion-proof and fire-extinguishing.

[0003] When coal mining operations are carried out underground, ventilation is usually required due to the need for oxygen supply or dilution of toxic gases, which causes a large amount of water in the water bags in the explosion-proof water shed to evaporate and decrease. Manual water replenishment is required in multiple water bags, but because the water bags are suspended in the air, manual water replenishment requires climbing up and down, which not only has low water replenishment efficiency but also is very dangerous. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that ventilation is usually required due to the need to supply oxygen or dilute toxic gases, which causes a large amount of water in the water bags in the explosion-proof water shed to evaporate and decrease, and it is necessary to manually replenish water in multiple water bags. However, since the water bags are suspended in the air, manual water replenishment requires climbing up and down, which not only has low water replenishment efficiency but also is very dangerous. An automatic water adding device for a mine explosion-proof water shed is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The water pump has a hook portion for connecting the water pipe to the water pump, and a bottom end of the hook portion for connecting the water pipe to the water pump, the hook portion for connecting the water pipe to the water pump is connected. The second slide bar is slidably connected; the fixed frame is fixedly connected with a mounting block on the side wall above the horizontal slide, and the mounting block is connected with a vertical downward rotating shaft, and the rotating shaft is sequentially sleeved with a gear, a limit ring and a torsion spring from top to bottom, and the bottom end of the rotating shaft is fixedly connected with the valve plate, and the valve plate is a circular structure, and the valve plate matches the pipe of the main water pipe; the front end of the second slide bar is provided with a second top block, and the second slide bar is also sleeved with a reset spring at the position between the second top block and the fixed frame, and the rear end of the second slide bar is fixedly connected with a toothed plate, and the toothed plate is meshed with the gear; when the floating block moves downward, the first top block moves downward and squeezes the second top block, and the toothed plate moves backward to drive the gear to rotate, the gear rotates the rotating shaft, and the rotating shaft rotates the valve plate, and the water supply pipeline of the main water pipe is opened; the floating block moves up and resets, the first top block moves up and disengages from the second top block, and under the elastic action of the reset spring, the second slide bar drives the toothed plate to move forward and reset, and under the elastic action of the torsion spring, the valve plate rotates and resets to close the water supply pipeline of the main water pipe.

[0007] A further optimization scheme is that at least one auxiliary water bag is provided on one side of the main water bag, and the auxiliary water bag is connected to the hanger through a hook, the main water bag and the auxiliary water bag are connected through a water pipe, and adjacent auxiliary water bags are also connected through a water pipe, and a one-way valve is provided on the water pipe.

[0008] Furthermore, the hook is fixedly connected to the bottom end of the rack, and a plurality of the hooks are evenly and symmetrically distributed on the rack.

[0009] Furthermore, the first top block and the second top block are both in arc-shaped structures, and the first top block is connected with the second top block in point contact.

[0011] Furthermore, the return spring is sleeved on the second slide rod, one end of the return spring is fixedly connected to the second top block, and the other end of the return spring is fixedly connected to the fixing frame.

[0012] The method for automatically adding water using the automatic water adding device for a mine explosion-proof water shed comprises the following steps:

[0013] 1) Add water to the water bag, fix it on the rack through the hook, and install the main water pipe;

[0014] 2) When the clean water in the inner cavity of the water bag evaporates, the water volume decreases. At this time, the floating block moves down with the water level, and the load-bearing rod moves down under the action of gravity, driving the second fixed shaft to move down, the second fixed shaft drives the first top block to move down, the first top block squeezes the second top block, the reset spring contracts, the second sliding rod moves backward, driving the toothed plate to move backward, the toothed plate drives the gear to rotate, the gear drives the rotating shaft to rotate, the rotating shaft drives the valve plate to rotate, the water delivery pipeline of the main water pipe is opened, and the tap water enters each water bag from the main water pipe, and the floating block moves up with the water level; the load-bearing rod moves up with the floating block, thereby moving the first top block up;

[0015] 3) When the float is reset, the first top block is separated from the second top block, and under the elastic action of the reset spring, the tooth plate moves forward and resets, and under the elastic action of the torsion spring, the valve plate rotates and resets, thereby closing the water supply pipeline of the main water pipe.

[0016] Furthermore, at least one auxiliary water bag is provided on one side of the main water bag in the automatic water-adding device for explosion-proof water shed for mines, and the auxiliary water bag is connected to the rack through a hook, and the main water bag and the auxiliary water bag are connected through a water pipe, and adjacent auxiliary water bags are also connected through a water pipe, and a one-way valve is provided on the water pipe; the main water bag and the auxiliary water bag are provided with water guide ports at the same height, and water guide ports are connected between adjacent water guide ports of different water bags;

[0017] When the water level in the main water bag rises to the water outlet, the clean water in the main water bag flows from the water pipe to the auxiliary water bag. The one-way valve allows the clean water to flow in one direction only in the water pipe. The clean water is transported between the auxiliary water bags and finally replenished to each auxiliary water bag until the water levels in the main water bag and the auxiliary water bags are equal again.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. The present invention provides a float, a water guide pipe and a valve plate. When the clean water in the main water bag or the auxiliary water bag evaporates, the float moves down with the water level, thereby causing the first top block to move down and squeeze the second top block, the tooth plate moves right and causes the gear to rotate, the gear causes the rotating shaft to rotate, the rotating shaft causes the valve plate to rotate, the water delivery pipeline of the main water pipe is opened, and tap water is transported from the water injection pipe to the main water bag, and then the water guide pipe transports it to each auxiliary water bag in turn. When the clean water in the main water bag and the auxiliary water bag is filled again, the water levels in the main water bag and the auxiliary water bag are parallel, the float moves up and resets, and the valve plate closes the water delivery pipeline of the main water pipe again, thereby realizing automatic water addition to multiple water bags.
