Description

Technical Field

[0001] This invention relates to the field of mining safety equipment technology, specifically to a water replenishment device for water bags inside an explosion-proof water shed. Background Technology

[0002] In coal mine production, my country's "Coal Mine Safety Regulations" clearly stipulate that explosion-proof facilities must be installed at the working faces of coal roadways in high-gas mines, and mines mining coal seams with the risk of coal dust explosions must have measures to prevent and isolate coal dust explosions. Among these measures, explosion-proof water canopies installed in roadways play an important role in explosion prevention and fire extinguishing, buffering explosions and fires to a certain extent, controlling the scope of the disaster, and thus reducing the damage to equipment and injuries to personnel caused by explosions and fires.

[0003] In coal mines, ventilation is necessary for purposes such as supplying oxygen, diluting harmful gases, and regulating the climate, and the ventilation speed is often very high. This causes a large amount of water to evaporate from the explosion-proof water tanks, rendering them ineffective for explosion isolation and suppression. Therefore, workers need to frequently replenish the water tanks. However, an explosion-proof water tank in a single tunnel often contains dozens or even hundreds of water bags, making the replenishment work extremely demanding. Furthermore, because the water bags are suspended at high altitudes, the replenishment process is very time-consuming, labor-intensive, and inefficient, resulting in low worker morale and often failing to meet the timely replenishment requirements. At the same time, vehicles, conveyor belts, and high-voltage overhead lines within the tunnels also threaten the safety of workers replenishing the water.

[0004] Some existing automatic water-filling explosion-proof water sheds or automatic water-filling devices for explosion-proof water sheds control automatic water filling through solenoid valves and level gauges installed in the water bags. However, this requires the installation of a large number of solenoid valves and level gauges, increasing costs and reducing the stability and reliability of the system. Therefore, it is necessary to develop an automatic method to replenish the water evaporated in the explosion-proof water shed, ensuring both the explosion-proof and explosion-suppressing effect of the explosion-proof water shed and the safety of workers. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems by providing a water replenishment device for water bags inside an explosion-proof water shelter.

[0021] The present invention will now be described in further detail with reference to the full text.

[0022] Combined with appendix Figure 1 and Figure 2 A water replenishment device for water bags inside an explosion-proof water shelter includes a bracket 1. A water storage bag 2, a main water bag 3, and a secondary water bag 4 are installed under the bracket 1. A water inlet device 5 connects the water storage bag 2 and the main water bag 3. Multiple secondary water bags 4 are connected in series via water pipes. The main water bag 3 and secondary water bags 4 are connected by water pipes. The water inlet device 5 is located 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 secondary water bags 4. The main water bag 3 and secondary water bags 4 are at the same height. This invention utilizes the height difference between the water storage bag 2 and the main water bag 3 and secondary water bags 4 to replenish water to the main water bag 3 and secondary water bags 4 in one go. Because the main water bag 3 and secondary water bags 4 are at the same height and connected by water pipes on one side of the main water bag 3 and secondary water bags 4, it can achieve autonomous water replenishment of the main water bag 3 and secondary water bags 4, meeting the requirement of timely water replenishment for the explosion-proof water shelter. At the same time, there is no need for workers to climb up and lie down to add water, making it highly safe.

[0023] In specific implementations of this invention, such as Figure 1 and Figure 2As 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 storage bag 2 via a water pipe. A partition 502 is installed inside the L-shaped connecting shell 501. A guide rod 503 is slidably connected inside the partition 502. The lower end of the guide rod 503 is connected to a float 504. An adjusting spring 505 is installed on the outside of the guide rod 503, between the float 504 and the partition 502. A limit plate 506 is installed on the guide rod 503. A matching guide rod 50 is provided inside the partition 502. 3. Using the through-hole, when a large amount of water evaporates from the main water bag 3 and the auxiliary water bag 4, causing the liquid level to drop, the compression force of the adjusting spring 505 decreases. The adjusting spring 505 extends, pushing the float 504 down close to the liquid surface. The water storage bag 2 enters the L-shaped connecting shell 501 through the water pipe to replenish the main water bag 3. The main water bag 3 and the auxiliary water bag 4 are at the same height, and multiple auxiliary water bags 4 are connected in series through water pipes. The liquid levels of the main water bag 3 and the auxiliary water bags 4 are the same, and the replenished water will enter the main water bag 3 and the auxiliary water bags 4 sequentially to achieve complete replenishment. When the replenished water in the main water bag 3 and the auxiliary water bag 4 pushes the float 504 to float to the top surface of the main water bag 3, the replenishment stops.

[0024] In specific implementations of this invention, such as Figure 2 As shown, a connecting device 7 for connecting the hanging bracket 1 is installed on the water storage bag 2. The connecting device 7 includes a connecting block 701 set on the water storage bag 2, a rotating ball 702 is movably installed in the connecting block 701, and a bolt 703 is installed on the rotating ball 702. A connecting hole is opened on the hanging bracket 1 to cooperate with the movement of the bolt 703. Fixing nuts are installed on the outside of the bolt 703 and at the upper and lower ends of the hanging bracket 1. Specifically, by moving the bolt 703 in the connecting hole and then fixing it with the two fixing nuts, the height of the water storage bag 2 can be adjusted.

[0025] One side of the water storage bag 2 is connected to an external water inlet pipe via a water pipe, and a switch valve is installed on the water inlet pipe. The auxiliary water bag 4, the main water bag 3 and the hanging frame 1 are connected by a hook 6. Specifically, the external water source is transported to the water storage bag 2 through a water pump and a water inlet pipe, and the switch valve can be used to turn the water on and off. Example

[0026] When a large amount of water evaporates from the main water bag 3 and the auxiliary water bag 4, and water needs to be replenished, the liquid level drops, the compression force of the adjusting spring 505 decreases, the adjusting spring 505 extends and pushes the float 504 down close to the liquid surface, and the water storage bag 2 enters the L-shaped connecting shell 501 through the water pipe to replenish the main water bag 3. The main water bag 3 and the auxiliary water bag 4 are at the same height, and multiple auxiliary water bags 4 are connected in series through water pipes. The liquid levels of the main water bag 3 and the auxiliary water bags 4 are the same, and the replenished water will enter the main water bag 3 and the auxiliary water bags 4 in sequence to achieve complete replenishment. The external water source is transported to the water storage bag 2 through the 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, which would cause the pressure in the main water bag 3 to be too high and prevent it from being transported. A single water inlet is sufficient to add water to the water bags, making installation and maintenance simple. Example

[0027] Compared to Embodiment 1, Embodiment 2 adds a connecting device 7, which can adjust the height of the water storage bag 2. The bag can be moved within the connecting hole by bolt 703 and then fixedly connected by two fixing nuts, thus realizing the height adjustment of the water storage bag 2. The installation and maintenance are simple.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, they should all fall within the protection scope of the present invention.
