Description

Technical Field

[0001] This utility model relates to the field of new energy, and in particular to a device for testing the waterproof performance of an energy storage box. Background Technology

[0002] Energy storage battery devices in energy storage systems not only store excess power generated by the power generation system, but also supply power to the grid when the power generation system is generating less electricity. This allows for the storage of off-peak electricity and its release during peak demand periods, effectively alleviating grid pressure and rationally allocating power resources. Containerized energy storage systems are typically deployed outdoors, placing stringent requirements on the storage cabinets' waterproof, dustproof, and thermal management performance. Since energy storage cabinets are generally placed in power plants, they need to be able to prevent rainwater intrusion, necessitating waterproof performance testing for the products.

[0003] A search of Chinese patents revealed publication number CN221386926U, entitled "Spray Gun Water Supply Isobaric Structure and Waterproof Performance Testing Device for Energy Storage Cabinets," which relates to the technical field of energy storage system testing equipment. The device includes a main water pipe connected to a distributor and housed within the frame of the testing apparatus; multiple spray gun assemblies arranged along the extension direction of the main water pipe, each connected to the main water pipe; each spray gun assembly includes a pressure-reducing section and a nozzle, with each pressure-reducing section having the same pressure threshold. The pressure value of the main water pipe is greater than the pressure threshold of the pressure-reducing section, and liquid is sprayed from the nozzle after being depressurized by the pressure-reducing section from the main water pipe. According to this invention, the pressure from the main water pipe to the spray gun assembly is controlled by the pressure-reducing section of each spray gun assembly, ensuring consistent outlet pressure values ​​for all spray gun assemblies on the same side of the main water pipe, resulting in uniform water volume at all heights, improving the testing accuracy of the apparatus, making the test results more accurate and reliable, and ensuring more stable operation of the apparatus.

[0004] Existing testing equipment is inconvenient for replacing nozzles. Generally, testing equipment uses multiple nozzles to spray water for testing. When a nozzle is damaged, it needs to be replaced. However, nozzles are usually connected to the nozzle pipe with bolts, requiring tools for disassembly and reassembly, which is cumbersome, increases workload, and reduces replacement efficiency. Furthermore, the distance between the nozzle and the energy storage tank cannot be adjusted. Sprayers are usually fixed on a bracket, resulting in a fixed position. When testing energy storage tanks of different sizes, if the nozzle is too close to the tank, the water pressure may be too high, causing local water pressure to exceed actual rainfall conditions, potentially overestimating the waterproof performance of the energy storage tank or even damaging the equipment. If the distance is too far, the water pressure may be insufficient, failing to fully simulate real rainfall intensity, leading to underestimation of waterproof capabilities and making the equipment inconvenient to use, reducing practicality and flexibility. To solve these problems, we propose a waterproof performance testing device for energy storage tanks. Utility Model Content

[0005] The purpose of this invention is to provide a waterproof performance testing device for energy storage boxes, which has the advantages of easy nozzle replacement and adjustable distance between the nozzle and the energy storage box.
