Description

Technical Field

[0001] The utility model relates to the technical field of mining safety equipment, in particular to a water replenishing device for water bags in an explosion-proof water shed. Background Technique

[0002] In coal mine production, coal dust or gas explosion accidents cause numerous casualties every year, bringing huge losses to the national economy. China's "Coal Mine Safety Regulations" clearly stipulate that explosion-proof facilities must be installed in the heading faces of coal roadways in high-gas coal mines, and mines mining coal seams with the risk of coal dust explosion must have measures to prevent and isolate coal dust explosion. Among them, the explosion-proof water shed installed in the roadway plays an important role in explosion prevention and fire extinguishing, playing a buffering role in explosion and fire to a certain extent, controlling the scope of disasters, and thus reducing the damage to equipment and the harm to personnel caused by explosion and fire.

[0003] In coal mines underground, ventilation is required for purposes such as supplying oxygen, diluting harmful gases, and regulating the climate, and the ventilation speed is very high. This causes a large amount of water in the explosion-proof water shed to evaporate, failing to achieve the purpose of explosion isolation and suppression. Therefore, workers need to frequently replenish water for the explosion-proof water shed. However, the explosion-proof water shed in a roadway often contains dozens or even hundreds of water bags, and the water replenishment workload is very large. Moreover, since the water bags are all suspended at high places, the process of workers replenishing water is very time-consuming, laborious, and inefficient, resulting in poor work enthusiasm of workers and often unable to meet the timeliness of replenishing water for the explosion-proof water shed. At the same time, equipment such as vehicles, belts, and high-voltage overhead lines in the roadway also pose threats to the safety of water adding workers.

[0004] Some existing automatic water adding explosion-proof water sheds or automatic water adding devices for explosion-proof water sheds control automatic water adding through solenoid valves and liquid level gauges arranged in the water bags. However, on the one hand, a large number of solenoid valves and liquid level gauges need to be added, increasing the cost and at the same time reducing the stability and reliability of the system. Therefore, it is necessary to involve a device for automatically replenishing the volatilized water in the explosion-proof water shed, which not only ensures the explosion isolation and suppression effect of the explosion-proof water shed but also ensures the safety of workers.

[0027] The following will further elaborate on the present utility model in combination with the full text.

[0028] Combined with the attached Figure 1 and Figure 2, A water replenishing device for water bags in an explosion-proof water shed, which includes a hanging rack 1. A water storage bag 2, a main water bag 3 and an auxiliary water bag 4 are installed under the hanging rack 1. There is a water inlet device 5 connected between the water storage bag 2 and the main water bag 3. The auxiliary water bags 4 are in multiple groups and are connected in series through water pipes. The main water bag 3 and the auxiliary water bags 4 are connected through a water pipe. The water inlet device 5 is arranged at the upper end of the main water bag 3. The height of the water storage bag 2 is higher than that of the main water bag 3 and the auxiliary water bags 4, and the heights of the main water bag 3 and the auxiliary water bags 4 are the same. Through the height difference between the water storage bag 2 and the main water bag 3 and the auxiliary water bags 4, the main water bag 3 and the auxiliary water bags 4 are replenished with water at one time by the water storage bag 2. Because the heights of the main water bag 3 and the auxiliary water bags 4 are the same and are connected through a water pipe, and the water pipe is connected to the upper side of one end of the main water bag 3 and the auxiliary water bags 4, the main water bag 3 and the auxiliary water bags 4 can be replenished with water automatically, meeting the timeliness of replenishing water for the explosion-proof water shed. At the same time, there is no need for workers to climb up and down to add water, and the safety is high.

[0029] When the present utility model is specifically implemented, as Figure 1 and Figure 2 shown, the water inlet device 5 includes an L-shaped connecting shell 501. The lower end of the L-shaped connecting shell 501 is connected to the main water bag 3 and one side is connected to the water storage bag 2 through a water pipe. A partition plate 502 is installed in the L-shaped connecting shell 501. A guide rod 503 is slidably connected in the partition plate 502. A floating plate 504 is connected to the lower end of the guide rod 503. An adjusting spring 505 is installed outside the guide rod 503 and between the floating plate 504 and the partition plate 502. A limiting disc 506 is installed on the guide rod 503. A through hole for cooperating with the guide rod 503 is opened in the partition plate 502. When a large amount of water in the main water bag 3 and the auxiliary water bags 4 evaporates and the liquid level drops, the compression force of the adjusting spring 505 decreases, and the adjusting spring 505 expands to push the floating plate 504 close to the liquid level and descend. The water storage bag 2 enters the L-shaped connecting shell 501 through the water pipe to replenish water to the main water bag 3. The heights of the main water bag 3 and the auxiliary water bags 4 are the same, and multiple auxiliary water bags 4 are connected in series through water pipes, and the liquid levels of the main water bag 3 and the auxiliary water bags 4 are the same. The replenished water will enter the main water bag 3 and the auxiliary water bags 4 in sequence to achieve full water replenishment. When the water replenishment of the main water bag 3 and the auxiliary water bags 4 pushes the floating plate 504 to float to the top surface of the main water bag 3, the water replenishment stops.

[0030] When the present utility model is specifically implemented, as Figure 2 shown, a connecting device 7 for connecting the hanging rack 1 is installed on the water storage bag 2. The connecting device 7 includes a connecting block 701 arranged on the water storage bag 2. A rotating ball 702 is movably installed in the connecting block 701. A bolt 703 is installed on the rotating ball 702. A communication hole for cooperating with the movement of the bolt 703 is opened on the hanging rack 1. Fixing nuts are installed on the outer side of the bolt 703 and at the upper and lower ends of the hanging rack 1. Specifically, by moving the bolt 703 in the communication hole and then fixing and connecting it through two fixing nuts, the height adjustment of the water storage bag 2 can be realized.

[0031] One side of the water storage bag 2 is connected to an external water inlet pipe through a water pipe, and a switch valve is installed on the water inlet pipe. The secondary water bag 4, the main water bag 3 and the hanging rack 1 are connected through a hook 6. Specifically, an external water source transports water from the outside into the water storage bag 2 through a water pump and the water inlet pipe, and the on-off can be realized through the switch valve. Embodiment 1

[0032] When a large amount of water in the main water bag 3 and the secondary water bag 4 evaporates and water replenishment is required, the liquid level drops, the compression force of the adjusting spring 505 decreases, and the adjusting spring 505 stretches to push the floating plate 504 close to the liquid level as it drops. The water storage bag 2 enters the L-shaped connecting shell 501 through the water pipe to replenish water to the main water bag 3. The main water bag 3 and the secondary water bag 4 are of the same height, and multiple secondary water bags 4 are connected in series through water pipes. The liquid levels of the main water bag 3 and the secondary water bag 4 are the same, and the water replenishment will enter the main water bag 3 and the secondary water bag 4 in sequence to achieve full water replenishment. An external water source transports water from the outside into the water storage bag 2 through a water pump and the water inlet pipe. At the same time, the water inlet device 5 can prevent the water in the water storage bag 2 from quickly entering the main water bag 3, resulting in excessive pressure in the main water bag 3 and inability to transport. Water can be added to the water bag through one water injection port, and the installation and maintenance are simple. Embodiment 2

[0033] Compared with Embodiment 1, Embodiment 2 adds a connecting device 7. The height of the water storage bag 2 can be adjusted through the connecting device 7. The bolt 703 moves in the communication hole and is then fixedly connected through two fixing nuts, so that the height adjustment of the water storage bag 2 can be realized, and the installation and maintenance are simple.

[0034] The above describes the present utility model and its embodiments. This description is not restrictive. What is shown throughout the text is only one of the embodiments of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural modes and embodiments to this technical solution without creative efforts without departing from the purpose of the creation of the present utility model, they shall fall within the protection scope of the present utility model.
