Description

Technical Field

[0001] This utility model relates to the field of energy storage fire protection technology, and in particular to an energy storage system with a high-pressure fine water mist device. Background Technology

[0002] Since the energy people need is highly time- and space-dependent, in order to make rational use of energy and improve energy efficiency, a device is needed to collect and store excess energy that is not used temporarily for a period of time, and then extract it for use during peak usage periods, or transport it to places with energy shortages for use. This method requires a large number of energy storage systems.

[0003] Current energy storage systems often incorporate water sprinkler systems and other gaseous fire suppression methods, such as perfluorohexanone, heptafluoropropane, and aerosols, outside the cabinet for fire suppression. However, once a fire breaks out in the energy storage system, water remains the ultimate extinguishing measure. Opening the cabinet door during firefighting is extremely dangerous for firefighters, yet it's the only way to allow water from the fire hoses to enter the cabinet. This illustrates how difficult it is to extinguish energy storage battery fires; water is the optimal extinguishing method, but the process is extremely risky. While current energy storage fire protection systems employ multiple layers of protection, the effectiveness of fire suppression outside the cabinet is not very significant.

[0004] Therefore, a safe method of fire extinguishing is urgently needed. Utility Model Content

[0034] This utility model provides an energy storage system with a high-pressure fine water mist device, comprising: a cabinet, a battery pack, and the high-pressure fine water mist device. The cabinet includes a compartment; the battery packs are disposed within the compartment, and there are several battery packs arranged in rows, with multiple rows forming a row. For example, a row of 8 battery packs is formed, with 4 rows forming the first row and 5 rows forming the second row, i.e., two rows. In some preferred embodiments, the compartment is a rectangular shell.

[0035] Figure 1 A schematic diagram of the high-pressure fine water mist device provided by this utility model is shown. Figure 2 A top view of the high-pressure fine water mist device is shown, such as... Figure 1-2 As shown, the high-pressure fine water mist device is installed in the cabinet.

[0036] The high-pressure fine water mist device includes: a main pipeline 110, a cabin fire extinguishing assembly, a battery pack fire extinguishing assembly, and a control valve 310. The output end of the control valve 310 is connected to the cabin fire extinguishing assembly and the battery pack fire extinguishing assembly via the main pipeline 110, and is used to control the working state of the cabin fire extinguishing assembly and the battery pack fire extinguishing assembly. Preferably, the input end of the control valve 310 is connected to a water pipe, and fire water is sequentially input to the cabin fire extinguishing assembly and the battery pack fire extinguishing assembly through the water pipe and the control valve 310. The working state includes a fire extinguishing state and a non-fire extinguishing state.

These fine water mist nozzles are used to form a fine water mist with a density of Dv0.5≤65um and Dv0.99≤100um under high pressure. During fire extinguishing, the high temperature causes the water mist to rapidly vaporize and absorb heat. Simultaneously, the continuous physical reaction process ensures the discontinuity of the water, effectively preventing damage caused by electrical conductivity.

[0038] Each energy storage system cabinet is equipped with a zone control valve on its outer wall. In the event of a fire, the zone control valve is opened via a control device to supply water to the pipes inside the energy storage system cabinet.

[0039] The fire extinguishing assembly for the cabin includes a U-shaped pipe 130 for introducing fine water mist into the cabin; the fire extinguishing assembly for the battery pack includes a U-shaped main pipe 120 for the battery pack and at least one branch pipe 410, wherein the branch pipe 410 is connected to the U-shaped main pipe 120 for introducing fine water mist into each battery pack.

[0044] The branch pipes 410 are spaced apart on the second branch 122 and the fourth branch 124, and extend vertically. The upper end of each branch pipe 410 connects to either the second branch 122 or the fourth branch 124, and each branch pipe 410 is correspondingly positioned in the column of the battery pack. In some embodiments, there are four branch pipes 410 on the second branch 122, corresponding to four columns of battery packs.

The electric valve 411 is located at the upper end of the vertical pipe 414 and is used to control the working state of the corresponding branch pipe 410. The horizontal pipes 412 are spaced apart, with one end of each horizontal pipe 412 connected to the vertical pipe 414, and the fine water mist nozzle 138 located at the other end of each horizontal pipe 412. Each horizontal pipe 412 corresponds to a battery pack, thus enabling the directional delivery of fine water mist to each battery pack. More preferably, the horizontal pipe 412 is a high-pressure hose, connected to the fine water mist nozzle 138 via a drip-proof device 413, and connected to the vertical pipe 414 via a tee. A compression elbow 415 is provided at the end of the vertical pipe 414.

[0046] The U-shaped pipe 130 of the cabin and the U-shaped main pipe 120 of the battery pack are connected by a connecting pipe. One end of the connecting pipe is located at the connection between the first branch 121 and the third branch 123, and the other end is connected to the U-shaped pipe 130 of the cabin.

[0049] Furthermore, a solenoid valve 140 is installed on the connecting pipe to control the working status of the cabin U-shaped pipe 130.

[0050] Furthermore, sensors are installed on the fine water mist nozzles 138 of the battery pack fire extinguishing components to monitor the fire situation and send signals to the control device. The control device controls the operating status of the corresponding battery pack fire extinguishing components based on the feedback signals, such as controlling the opening of the electric valve 411 of the corresponding battery pack. The control device includes a computer.

[0051] Figure 3 A side view of a high-pressure fine water mist device is shown. Figure 3 The control valve 310 extends vertically, as does the main pipe 110. The vertical pipe 414 extends vertically and is long enough to reach the bottommost battery pack, thus extinguishing the fire in each corresponding battery pack. Here, "vertical" refers to the height of the cabinet.

[0052] The energy storage system provided by this utility model is equipped with a cabin fire extinguishing component and a battery pack fire extinguishing component, which can extinguish fires in the cabin and the battery pack respectively; the fine water mist has little harm to the equipment, and the power supply equipment can still be used normally within 30 minutes of spraying water.
