Description

Technical Field

[0001] This utility model belongs to the field of energy storage battery technology for energy storage power stations, and specifically relates to energy storage battery cabinets for energy storage power stations. Background Technology

[0002] With the rapid development of the new energy industry, the global demand for containerized energy storage batteries is also increasing. Containerized energy storage batteries are a system used to store and transport energy storage batteries. A complete energy storage container mainly consists of battery packs, battery management systems (BMS), energy management systems (EMS), energy storage inverters (PCS), and other electrical equipment. Among them, the battery pack accounts for the highest cost, about 60%, followed by the energy storage inverter at about 15%, and the battery management system and energy management system together account for about 15%.

[0003] Most existing battery cabinets have a top lift-up panel that can be opened to dissipate heat. However, with only the top panel open, the airflow inside the battery cabinet is poor. At the same time, outside air enters the battery cabinet directly through the gap after the top panel is opened, and dust in the outside air can easily fall onto the battery surface. Dust accumulates on the battery surface, which reduces the battery's heat dissipation efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an energy storage battery cabinet for an energy storage power station, in order to solve the problem mentioned in the background art that most existing battery cabinets only open the top lifting plate to dissipate heat. However, if only the top plate is opened, the air circulation inside the battery cabinet is poor. At the same time, outside air directly enters the battery cabinet through the gap after the top plate is opened, and dust in the outside air can easily fall onto the battery surface. Dust accumulates on the battery surface, thereby reducing the heat dissipation efficiency of the battery.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a battery cabinet body and mounting plates disposed on the left and right sides of the battery cabinet body. Two bolts are threaded onto each mounting plate, with the tail ends of the bolts threadedly connected to the battery cabinet body. Several U-shaped cooling pipes are mounted on the two mounting plates. Adjacent cooling pipes are connected by a connecting pipe. The cooling pipes are S-shaped. A U-shaped fixing plate is mounted on the rear side of both mounting plates. A water pump is mounted on the rear side of the fixing plate. A liquid delivery pipe is connected to the outlet of the water pump. The liquid delivery pipe is connected to a cooling pipe located at the bottom. A connecting pipe is connected to one end of a cooling pipe located at the top. A return pipe is connected to one end of the connecting pipe. A suction pipe is connected to the inlet of the water pump. One end of the return pipe is connected to the suction pipe. One end of the suction pipe is connected to an external pipe via a filter assembly. Several ventilation channels are provided on both the left and right sides of the battery cabinet body.

[0006] The above solution involves installing a water pump, cooling pipes, connecting pipe 1, return pipe, and extraction pipe. The cooling pipes and water pump are secured using mounting plates and bolts. Connecting pipe 1 connects the cooling pipes, and the extraction pipe works in conjunction with the extraction of coolant. The flow of coolant on the outside of the battery cabinet body allows for timely heat dissipation. The return pipe enables the coolant to be reused, saving water resources. This solution ensures ventilation inside the battery cabinet body while preventing dust from entering.

[0007] In the above scheme, it should be noted that the water pump is electrically connected to an external power source.

[0008] In a preferred embodiment, two slots are provided on both the left and right sides of the battery cabinet body, and a card plate is installed on the opposite side of the two mounting plates. The two card plates on the same side are slidably installed in the two slots respectively.

[0009] By adopting the above solution, the installation position of the mounting plate is determined by setting a card plate and utilizing the cooperation between the card plate and the card slot, thereby facilitating and speeding up the installation of the mounting plate and preventing the mounting plate from tilting during the installation process.

[0010] In a preferred embodiment, two fixing slots are provided on the rear side of the battery cabinet body, and fixing rods are provided in the fixing slots. Both fixing rods are installed on the front side of the horizontal part of the fixing plate.

[0011] By adopting the above solution, the fixed rod is set up, and the fixed rod and the fixed groove cooperate to strengthen the support of the fixed plate, thereby improving the firmness of the fixed plate. This allows the fixed plate to stably support the water pump, further improving the stability of the water pump.

[0012] In a preferred embodiment, four slots are provided on both the left and right sides of the battery cabinet body. Each slot contains a pin, and one end of each of the four pins on the same side is fitted with the same dust cover, which is located on one side of the ventilation channel.

[0013] By adopting the above solution, a pin and a dust cover are installed. The dust cover blocks the ventilation channel, thereby filtering out external dust and preventing it from entering the battery cabinet body through the ventilation channel. This keeps the inside of the battery cabinet clean. The pin and slot work together to fix the dust cover in place and also make it easy to remove the dust cover at any time.

[0014] In a preferred embodiment, the filtration assembly includes a filter box with an open upper surface, the filter box being connected to one end of a liquid extraction pipe, and an external connecting pipe being connected to the rear side of the filter box. A filter screen is provided inside the filter box, and a cover plate is provided on the upper surface of the filter box. The top end of the filter screen is fixedly connected to the cover plate, and the filter screen is located between the liquid extraction pipe and the external connecting pipe.

[0015] The above solution involves setting up a filter box, a cover plate, and a filter screen. The filter box connects the external pipe to the liquid extraction pipe, the cover plate provides fixed support for the filter screen, and the filter screen is placed inside the filter box. The filter screen filters and cleans the coolant in a timely manner, thus preventing the coolant from becoming cloudy. The cover plate seals and covers the top of the filter box.

[0016] In a preferred embodiment, L-shaped buckles are hinged to both the left and right sides of the filter box. The horizontal portion of the buckle is located above the cover plate, and a fastening bolt is threaded onto the horizontal portion of the buckle, which is threadedly connected to the cover plate.

[0017] Using the above solution, by setting up a buckle plate and a fastening bolt, the buckle plate is used to clamp the cover plate, and the fastening bolt is used to fix the buckle plate and the fastening bolt together, thereby fixing the cover plate to the filter box. This also makes it easy to loosen the fastening bolt and disassemble the cover plate at any time later.

[0018] In a preferred embodiment, two sets of limiting posts are installed on both the front and rear sides of the inner wall of the filter box, with two limiting posts in each set, and one end of each limiting post abutting against the filter screen.

[0019] By adopting the above scheme, the filter screen is reinforced and fixed by setting limiting posts, which are grouped in pairs on the front and rear sides of the filter screen. This prevents the coolant from impacting the filter screen when it enters the filter box, thereby improving the stability of the filter screen and enabling it to work stably.

[0020] In a preferred embodiment, one end of the outer tube is provided with a threaded cap, the threaded cap being threadedly connected to the outer tube and the opening of the outer tube being tightly fitted to the inner wall surface of the threaded cap.

[0021] By adopting the above solution, a threaded cap is installed, which, together with the external pipe, seals one end of the external pipe, thereby preventing the accumulation of dust or impurities inside the pipe opening and thus avoiding blockage of the external pipe.

[0030] Please see Figure 1-4This utility model provides an energy storage battery cabinet for an energy storage power station, including a battery cabinet body 1 and mounting plates 2 disposed on the left and right sides of the battery cabinet body 1. Several cooling pipes 4 are fixedly supported by the mounting plates 2. Two bolts 3 are threadedly installed on the mounting plates 2 for threaded fixation. The tail ends of the bolts 3 are threadedly connected to the battery cabinet body 1. Several U-shaped cooling pipes 4 are installed on the two mounting plates 2 for cooling the battery cabinet body 1. Adjacent cooling pipes 4 are connected to the mounting plates 2. A connecting pipe 5 is installed to connect two adjacent cooling pipes 4. Several cooling pipes 4 are arranged in an S-shape. A U-shaped fixing plate 6 is installed on the rear side of two mounting plates 2. The fixing plate 6 is used to fix and support the water pump 7. The water pump 7 is installed on the rear side of the fixing plate 6 and is used to draw coolant. The outlet of the water pump 7 is connected to a delivery pipe 8, which is used to transport coolant. The delivery pipe 8 is connected to the cooling pipe 4 located at the bottom and the cooling pipe 4 located at the top. One end of the 4 is connected to a connecting pipe 2 12, which connects to the return pipe 11. One end of the connecting pipe 2 12 is connected to the return pipe 11, which is used to return the cooled liquid. The inlet of the water pump 7 is connected to the suction pipe 9. One end of the return pipe 11 is connected to the suction pipe 9. One end of the suction pipe 9 is connected to the external pipe 17 through a filter assembly. Several ventilation channels are opened on both the left and right sides of the battery cabinet body 1. The water pump 7, cooling pipe 4, and connecting pipe 1 are installed to facilitate ventilation. The return pipe 11 and the liquid extraction pipe 9 are used to fix the cooling pipe 4 and the water pump 7 by using the mounting plate 2 and bolts 3. The cooling pipe 4 is connected by the connecting pipe 5. With the liquid extraction work of the liquid extraction pipe 9, the heat inside the battery cabinet body 1 can be dissipated in time by the flow of coolant on the outside of the battery cabinet body 1. Combined with the function of the return pipe 11, the coolant can be reused, saving water resources. While ensuring ventilation inside the battery cabinet body 1, dust is prevented from entering the battery cabinet body 1.

[0031] Two slots are provided on both the left and right sides of the battery cabinet body 1 to accommodate the mounting plate 23. The mounting plates 23 are installed on the opposite sides of the two mounting plates 2 to position the mounting plates 2. The two mounting plates 23 on the same side are slidably installed in the two slots. By setting the mounting plates 23, the installation position of the mounting plates 2 is determined by the cooperation between the mounting plates 23 and the slots, which facilitates and speeds up the installation of the mounting plates 2 and avoids the mounting plates 2 from tilting during the installation process.

[0032] Two fixing slots are provided on the rear side of the battery cabinet body 1. The fixing slots are used to accommodate one end of the fixing rod 13. The fixing rod 13 is installed in the fixing slot and is used to reinforce the fixing plate 6. Both fixing rods 13 are installed on the front side of the horizontal part of the fixing plate 6. By setting the fixing rod 13, the fixing rod 13 and the fixing slot are used to strengthen the support of the fixing plate 6, thereby improving the firmness of the fixing plate 6. This allows the fixing plate 6 to stably support the water pump 7, further improving the stability of the water pump 7.

[0033] Four slots are provided on both the left and right sides of the battery cabinet body 1. The slots are used to accommodate one end of the plug rod. The slots are equipped with pins 15, which are used to fix the dust cover 14. The same dust cover 14 is installed on one end of the four pins 15 on the same side. The dust cover 14 is located on one side of the ventilation channel. By setting the pins 15 and the dust cover 14, the dust cover 14 is used to block the ventilation channel, thereby blocking and filtering the dust from the outside and preventing the dust from entering the battery cabinet body 1 through the ventilation channel, thus maintaining the cleanliness of the inside of the battery cabinet body 1. The pins 15 and the slots work together to fix the dust cover 14 and also make it easy to remove the dust cover 14 at any time.

[0034] The filter assembly includes a filter box 16 with an open upper surface, on which a filter screen 22 is placed. The filter box 16 is connected to one end of a liquid extraction pipe 9, and an external pipe 17 is connected to the rear side of the filter box 16. The filter screen 22 is installed inside the filter box 16 to filter the coolant. A cover plate 18 is provided on the upper surface of the filter box 16 to cover the top of the filter box 16. The top of the filter screen 22 is fixedly connected to the cover plate 18. The filter screen 22 is located between the liquid extraction pipe 9 and the external pipe 17. By setting up the filter box 16, the cover plate 18 and the filter screen 22, the external pipe 17 is connected to the liquid extraction pipe 9 by the function of the filter box 16, and the filter screen 22 is fixedly supported by the function of the cover plate 18. The filter screen 22 is placed in the filter box 16, and the filter screen 22 filters and cleans the coolant in a timely manner, thereby avoiding the phenomenon of turbidity in the coolant. The cover plate 18 seals and covers the top of the filter box 16.

[0035] L-shaped latches 19 are hinged to both sides of the filter box 16. The horizontal part of the latches 19 is located above the cover plate 18. Fastening bolts 20 are threaded onto the horizontal part of the latches 19. The fastening bolts 20 are threaded to the cover plate 18. By setting the latches 19 and fastening bolts 20, the cover plate 18 is clamped by the latches 19. Combined with the fastening bolts 20, the clamping plate 23 is threaded together with the fastening bolts 20, thereby fixing the cover plate 18 to the filter box 16. This also makes it easy to loosen the fastening bolts 20 and disassemble the cover plate 18 at any time.

[0036] Two sets of limiting posts 21 are installed on the front and rear sides of the inner wall of the filter box 16. Each set of limiting posts 21 consists of two posts. One end of the limiting posts 21 abuts against the filter screen plate 22. By setting the limiting posts 21, the filter screen plate 22 is reinforced and fixed by the two groups of limiting posts 21 located on the front and rear sides of the filter screen plate 22. This prevents the coolant from impacting the filter screen plate 22 when it enters the filter box 16, thereby improving the stability of the filter screen plate 22 and enabling the filter screen plate 22 to work stably.

[0037] A threaded cap 10 is provided at one end of the outer pipe 17. The threaded cap 10 is threadedly connected to the outer pipe 17, and the opening of the outer pipe 17 is tightly fitted to the inner wall surface of the threaded cap 10. By providing the threaded cap 10, the threaded cap 10 and the outer pipe 17 work together to seal one end of the outer pipe 17, thereby preventing the accumulation of dust or impurities in the opening of the outer pipe 17 and thus preventing the outer pipe 17 from becoming blocked.

[0038] In use, place the two mounting plates 2 on the left and right sides of the battery cabinet body 1, then move the mounting plates 2. The movement of the mounting plates 2 causes the clamping plates 23 to move, and the clamping plates 23 slide in the slots. Then, rotate the bolts 3 to fix the mounting plates 2. At this time, the fixing plate 6 moves with the movement of the mounting plates 2, and the fixing plate 6 drives the fixing rod 13 to move. At this time, one end of the fixing rod 13 extends into the fixing groove. Then, rotate the threaded cap 10, and remove the threaded cap 10 from one end of the external connecting pipe 17. Connect the external connecting pipe 17 to the external cooling water source and start the water pump 7. The water pump 7 draws coolant through the liquid extraction pipe 9. The coolant enters the filter box 16, and after being filtered by the filter screen 22, it enters the delivery pipe 8. Then, it enters the cooling pipe 4 through the delivery pipe 8. The coolant in the cooling pipe 4 enters several cooling pipes 4 in sequence through the connecting pipe 5. The coolant cools the battery cabinet body 1. The heat in the battery cabinet is cooled and dissipated in a timely manner. After cooling, the coolant enters the return pipe 11 through the connecting pipe 2 12, and then the battery cabinet body 1 is cooled and dissipated repeatedly, which accelerates the dissipation of heat on the battery cabinet body 1. The dust cover 14 is used to block the ventilation channel, thereby blocking and filtering the external dust and preventing dust from entering the battery cabinet body 1 through the ventilation channel, thus maintaining the cleanliness of the inside of the battery cabinet body 1. Combined with the action of the pin 15 and the slot, the dust cover 14 is fixed and can be removed at any time. When it is necessary to remove the filter screen 22, loosen the fastening bolt 20, and then open the buckle. The buckle opens from the cover plate 18. Move the cover plate 18 upward. The movement of the cover plate 18 moves the filter screen 22. The filter screen 22 is gradually moved out of the filter box 16, and then the filter screen 22 can be removed for cleaning.
