Description

Technical Field

[0001] This utility model belongs to the field of energy storage fire extinguishing technology, specifically relating to a water mist spraying mechanism of an electrochemical energy storage fire suppression device. Background Technology

[0002] With the increasing demand for energy and growing concern for environmental issues, new energy conversion technologies are gradually becoming the forefront of scientific research. Among them, electrochemical energy storage, as a technology with broad application prospects, has received increasing attention. However, the lithium-ion batteries used in electrochemical energy storage boxes are essentially chemical components containing high-energy substances, which are prone to fire during use. In order to effectively deal with electrochemical energy storage fires, water mist spraying mechanisms, as an important fire extinguishing method, can atomize water into tiny droplets and spray them onto the fire area, which can quickly reduce the combustion temperature, suppress the spread of fire, and buy valuable time for fire extinguishing.

[0003] Existing water mist spraying mechanisms within electrochemical energy storage tanks connect to an external water source. A high-pressure water pump pressurizes the water, which is then sprayed into the nozzles to extinguish the fire. However, in actual operation, when the high-pressure pump or other power equipment starts or stops, or when system pressure fluctuates, the water pressure inside the nozzles can surge dramatically. Excessive pressure can damage the nozzles themselves, such as deforming or cracking the nozzle orifices, affecting the normal spraying effect of the water mist, causing uneven particle size and changes in spray angle, thus reducing fire extinguishing efficiency. Furthermore, prolonged exposure to high pressure accelerates the aging and damage of the nozzles and related connecting components, shortening equipment lifespan and increasing maintenance costs. In addition, excessively high water pressure that cannot be released can cause loosening of pipe connections and leaks, and in severe cases, can even paralyze the entire water mist spraying system, rendering it unable to perform its intended fire extinguishing function. Utility Model Content

[0004] The purpose of this invention is to provide a water mist spraying mechanism for an electrochemical energy storage fire suppression device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water mist spraying mechanism for an electrochemical energy storage fire suppression device, comprising:

[0006] The base has an energy storage box connected to its top. The energy storage box has a cabinet door hinged to its surface. Several shelves are connected inside the energy storage box. The top of the energy storage box is equipped with a spray assembly for suppressing fires inside the energy storage box. The high-pressure water pump of the spray assembly pumps water into the water supply pipe inside the energy storage box so that the water in the water supply pipe can be sprayed to the fire location through water mist nozzles.

[0007] A pressure relief assembly is installed inside the water mist nozzle to reduce the water pressure inside the nozzle. The sealing block of the pressure relief assembly releases the seal on the pressure relief pipe, allowing the water pressure to be discharged from the water mist nozzle through the pressure relief pipe.

[0008] Preferably, the spraying assembly includes a transfer box, which is located inside the top of the energy storage box and a high-pressure water pump is located on one side of the transfer box. The outlet of the high-pressure water pump is connected to the transfer box through a pipe, and the inlet is connected to an inlet interface.

[0009] Preferably, the water supply pipe is provided in two sets and is respectively located on both sides of the energy storage box. One end of the water supply pipe is connected to the transfer box, and a solenoid valve is provided at the connection point between the water supply pipe and the transfer box.

[0010] Preferably, the water mist nozzles are provided in several groups, and one end of the water mist nozzles is threadedly connected to a connecting pipe. One end of the connecting pipe is threadedly connected to a water supply pipe, and a filter screen for filtering water is provided inside the connecting pipe.

[0011] Preferably, the pressure relief assembly includes a convex tube, which is connected to a connecting pipe, and a sleeve is provided inside the convex tube, with a connecting rod slidably connected inside the sleeve.

[0012] Preferably, one end of the connecting rod slides through the sleeve and connects to the sealing block, the surface of the sealing block is connected to a sealing gasket, and the pressure relief pipe is located at the bottom of the convex pipe and the top of the pressure relief pipe is connected to the convex pipe.

[0013] Preferably, one end of the connecting rod located inside the sleeve is connected to a spring, and the other end of the spring is connected to the sleeve.

[0014] Preferably, a smoke sensor is installed inside the top of the energy storage box.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By installing a pressure relief component inside the water mist nozzle, when the high-pressure water pump starts and causes a sudden and significant increase in water pressure inside the nozzle, the sealing block of the pressure relief component will disengage from the pressure relief pipe, allowing the excessive water pressure to be discharged through the pressure relief pipe. This effectively avoids damage to the nozzle itself caused by water pressure, prevents nozzle deformation and cracking, ensures long-term stable operation of the water mist nozzle, extends the service life of the nozzle and related connecting parts, and reduces maintenance costs.

[0017] A filter screen is installed inside the connecting pipe to filter the water entering the water mist nozzle, effectively intercepting impurities in the water and preventing impurities from clogging the nozzles. This further ensures the normal spraying effect of the water mist, making the sprayed water mist more uniform and fine, and enhancing the fire extinguishing effect. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-4 The water mist injection mechanism of the electrochemical energy storage fire suppression device shown includes:

[0025] The base 1 has an energy storage box 2 connected to its top. The energy storage box 2 has a cabinet door 3 hinged to its surface. Several shelves 4 are connected inside the energy storage box 2. A spray assembly for suppressing fire inside the energy storage box 2 is provided inside the top of the energy storage box 2. The high-pressure water pump 5 of the spray assembly pumps water into the water supply pipe 6 inside the energy storage box 2 so that the water in the water supply pipe 6 can be sprayed to the fire location through the water mist nozzle 7.

[0026] A pressure relief assembly is provided inside the water mist nozzle 7 to reduce the water pressure inside the water mist nozzle 7. The sealing block 8 of the pressure relief assembly releases the seal on the pressure relief pipe 9 so that the water pressure can be discharged from the water mist nozzle 7 through the pressure relief pipe 9.

[0027] The spraying assembly includes a transfer box 10, which is located inside the top of the energy storage box 2 and a high-pressure water pump 5 is located on one side of the transfer box 10. The outlet of the high-pressure water pump 5 is connected to the transfer box 10 through a pipe, and the inlet is connected to an inlet interface 11.

[0028] The water supply pipe 6 is provided in two sets and is respectively located on both sides of the energy storage box 2. One end of the water supply pipe 6 is connected to the transfer box 10, and a solenoid valve 12 is provided at the connection point between the water supply pipe 6 and the transfer box 10.

[0029] The water mist nozzle 7 is provided in several groups and one end of the water mist nozzle 7 is threadedly connected to a connecting pipe 13. One end of the connecting pipe 13 is threadedly connected to the water supply pipe 6. The connecting pipe 13 is provided with a filter screen 14 for filtering water. By filtering the water through the filter screen 14, impurities that may exist in the water can be removed, ensuring the quality of the sprayed water mist.

[0030] The pressure relief assembly includes a convex tube 15, which is connected to a connecting pipe 13. A sleeve 16 is provided inside the convex tube 15, and a connecting rod 17 is slidably connected inside the sleeve 16.

[0031] One end of the connecting rod 17 slides through the sleeve 16 and connects to the sealing block 8. A sealing gasket 20 is connected to the surface of the sealing block 8. The pressure relief pipe 9 is located at the bottom of the convex pipe 15 and the top of the pressure relief pipe 9 is connected to the convex pipe 15. The sealing gasket 20 is tightly connected to the surface of the sealing block 8, which can play a good sealing role.

[0032] One end of the connecting rod 17 located inside the sleeve 16 is connected to a spring 18, and the other end of the spring 18 is connected to the sleeve 16.

[0033] A smoke sensor 19 is installed inside the top of the energy storage box 2.

[0034] When a fire occurs inside the energy storage tank 2, the smoke concentration will rise rapidly. The smoke sensor 19 inside the top of the energy storage tank 2 monitors the smoke situation in the tank in real time. Once the smoke concentration exceeds the preset threshold, the smoke sensor 19 will send a signal to the control system connected to it (not shown in the attached figure). After receiving the signal, the control system will immediately issue a command to start the high-pressure water pump 5 in the spray assembly and open the solenoid valve 12 at the connection between the water supply pipe 6 and the transfer box 10. The entire water mist spray mechanism will start working.

[0035] When the high-pressure water pump 5 starts, since the water inlet 11 is connected to the external water source, the high-pressure water pump 5 draws water from the external water source and pressurizes it. The pressurized water is then transported to the transfer box 10 through the pipeline. The transfer box 10 plays the role of buffering and stabilizing the water pressure, making the water pressure entering the water supply pipe 6 more stable, which helps the water mist nozzle 7 to spray water evenly.

[0036] Under pressure, the water in the transfer box 10 flows into the water pipes 6 located on both sides of the energy storage box 2. The water pipes 6 deliver the water to each water mist nozzle 7. The water enters the water mist nozzle 7 through the connecting pipe 13. Inside the connecting pipe 13, the filter screen 14 filters the water to remove any impurities that may be present in the water, ensuring the quality of the sprayed water mist. Under high pressure, the water is sprayed out from the water mist nozzle 7, forming a fine water mist that sprays into the energy storage box 2 to extinguish the fire. At the same time, the fine water mist forms a water mist curtain in the air, blocking the contact between the air and the burning material, reducing the oxygen supply required for combustion, and thus suppressing the fire in the energy storage box 2.

[0037] Under normal operating conditions, the spring 18 in the pressure relief assembly is in its natural state, and the sealing block 8 is tightly fitted to the top of the pressure relief pipe 9 under the elastic force of the spring 18, sealing the pressure relief pipe 9. When the high-pressure water pump 5 starts and pressurizes water into the connecting pipe 13, the water pressure in the connecting pipe 13 and the water mist nozzle 7 increases dramatically. The increased water pressure will exert a force on the sealing block 8 that is greater than the elastic force of the spring 18. Under this force, the sealing block 8 overcomes the elastic force of the spring 18 and drives the connecting rod 17 to slide into the sleeve 16, causing the sealing block 8 to disengage from the seal on the pressure relief pipe 9. At this time, part of the excessive water pressure is discharged through the pressure relief pipe 9, and part is sprayed out through the water mist nozzle 7, reducing the water pressure in the nozzle and achieving water pressure balance. When the water pressure returns to normal, the elastic force of the spring 18 will push the connecting rod 17 and the sealing block 8 to reset, resealing the pressure relief pipe 9, ensuring that the water mist nozzle 7 works stably under normal water pressure.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
