Description

Technical Field

[0001] This utility model relates to the field of heat dissipation and ventilation technology, and in particular to a heat dissipation and ventilation device for a lithium battery energy storage power station. Background Technology

[0002] Guided by the "dual carbon" goals, the world is accelerating its transition to clean energy. Lithium-ion battery energy storage power stations, as key facilities for peak shaving and valley filling in the power system and improving the capacity for renewable energy absorption, are experiencing explosive growth. During the charging and discharging process of lithium-ion batteries, the electrochemical reaction generates a large amount of Joule heat. If the heat accumulates and cannot be dissipated in time, the battery temperature will rise sharply.

[0003] Currently, the heat dissipation and ventilation device of a lithium-ion battery energy storage power station has poor heat dissipation effect. Its cooling fan is fixed in one position, and the heat dissipation effect of one position becomes worse for positions further away from the fan. This has significant limitations and poor practicality. In addition, due to the placement of the heat dissipation vents, rainwater can enter the main body of the energy storage power station through the vents during rain, which may cause damage to its internal electronic components, further reducing its practicality. Utility Model Content

[0004] The purpose of this invention is to solve the problems of poor heat dissipation in existing technologies, where the cooling fan is fixed in one position and the heat dissipation effect is poor when the fan is far away, and the setting of the heat dissipation vent allows rainwater to enter the main body of the energy storage power station during rain, which may damage the internal electronic components. Therefore, this invention proposes a heat dissipation and ventilation device for lithium battery energy storage power stations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heat dissipation and ventilation device for a lithium battery energy storage power station, comprising an energy storage station body, two connecting cavities at both ends of the energy storage station body, a housing fixed at both ends of the energy storage station body on the outside of each connecting cavity, an inclined plate fixed inside each of the four housings, the inclined plate having an outward downward inclined opening, a support plate at one end of the energy storage station body located in each of the two connecting cavities, a first motor mounted on the end of the two support plates facing inward of the energy storage station body by screws, a fan fixed at the output end of the first motor, and a drive structure for driving the two support plates to move in opposite directions or in opposite directions inside the energy storage station body.

[0006] Preferably, the drive structure includes a second motor installed inside the main body of the energy storage station. The output end of the second motor is fixed with a bidirectional screw. Two connecting blocks are fixed on both sides of one end of each of the two support plates. A movable plate is fixed on the end of each of the four connecting blocks away from the support plates. Two of the connecting blocks are threadedly connected to both ends of the bidirectional screw, and the other two connecting blocks are slidably connected with limit posts.

[0007] Preferably, the end of the bidirectional screw away from the second motor is rotatably connected to the main body of the energy storage station, and both ends of the limiting column are fixed to the main body of the energy storage station.

[0008] Preferably, the main body of the energy storage station has movable grooves on both sides at one end that match the connecting block, and the support plate has multiple connecting grooves.

[0009] Preferably, a baffle plate is installed on the inner wall of one of the two communicating cavities on the side of the fan by screws.

[0010] Preferably, both ends of the main body of the energy storage station are connected to door panels by pins, and safety locks are installed on both the door panels and the outer wall of the main body of the energy storage station.

[0011] Preferably, a second handle is fixed on the outer wall of each of the two door panels.

[0012] Preferably, a dustproof plate is inserted into the chassis, and a mounting plate is fixed to the side of the dustproof plate. The mounting plate is fixed to the chassis by bolts.

[0013] Preferably, a sealing block is fixed to the top of the dustproof plate, and a first handle is fixed to the top of the sealing block.

[0014] Preferably, the bottom of the chassis has multiple drainage holes located between the dustproof plate and the inclined plate.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] In this invention, the space inside the main body of the energy storage station is divided into two parts. By using two fans, both parts of the main body can be simultaneously cooled, resulting in better heat dissipation. Furthermore, the operation of the second motor drives a bidirectional screw to rotate. Through the coordination of the connecting block, the moving plate, and the limiting column, the two support plates can move in opposite directions, thereby adjusting the position of the two fans. The two fans can essentially cover their respective areas, overcoming the limitations of traditional single or fixed fans. This results in better heat dissipation and greater practicality. Additionally, the device features an inclined plate inside the casing with a downward-sloping opening, effectively blocking rainwater from entering the casing through the dustproof plate. The drainage holes allow rainwater to be discharged from the casing, further enhancing its practicality. Attached Figure Description

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as Figure 1-5 As shown, this utility model provides a heat dissipation and ventilation device for a lithium battery energy storage power station, including an energy storage station body 1. Two connecting cavities 2 are opened at both ends of the energy storage station body 1. A housing 3 is fixed at both ends of the energy storage station body 1 on the outside of each connecting cavity 2. An inclined plate 4 is fixed in each of the four housings 3. An inclined opening 5 is opened in the inclined plate 4 facing outward and downward. A support plate 12 is provided at one end of the energy storage station body 1 in each of the two connecting cavities 2. A first motor 13 is installed on the end of the two support plates 12 facing the inside of the energy storage station body 1 by screws. A fan 14 is fixed at the output end of the first motor 13. A drive structure 16 is provided inside the energy storage station body 1 for driving the two support plates 12 to move in opposite directions.

[0026] The overall effect of Embodiment 1 is that the device divides the space inside the main body 1 of the energy storage station into two parts through four connecting cavities 2. With the setting of two fans 14, the two parts inside the main body 1 of the energy storage station can be cooled synchronously at the same time, resulting in better heat dissipation. Moreover, through the operation of the drive structure 16, the two support plates 12 can be moved in opposite directions, thereby adjusting the position of the two fans 14. The two fans 14 can basically cover the area they are responsible for, which is equivalent to the limitations of traditional single fans 14 and fixed fans 14. This heat dissipation effect is better and more practical. In addition, the device has a sloping plate 4 inside the chassis 3, and the sloping plate 4 has a downward sloping opening 5, which can effectively block rainwater from entering the chassis 3 through the dustproof plate 6. And through the setting of the drainage hole 11, the rainwater entering the chassis 3 can be discharged, making it more practical.

[0027] Example 2, as Figure 1-5As shown, the drive structure 16 includes a second motor 1601 installed inside the energy storage station body 1. A bidirectional screw 1602 is fixed to the output end of the second motor 1601. Two connecting blocks 1603 are fixed to both sides of one end of each of the two support plates 12. A movable plate 1604 is fixed to the end of each of the four connecting blocks 1603 away from the support plates 12. Two connecting blocks 1603 are threadedly connected to both ends of the bidirectional screw 1602, and the other two connecting blocks 1603 are slidably connected to a limit post 1605. The end of the bidirectional screw 1602 away from the second motor 1601 is rotatably connected to the energy storage station body 1. Both ends of the limit post 1605 are fixed to the energy storage station body 1. Connecting plates 1604 are opened on both sides of one end of the energy storage station body 1. The moving slot 17 that matches the connecting block 1603 has multiple connecting slots 15 in the support plate 12. The inner walls of the two connecting cavities 2 are equipped with baffle plates 18 on one side of the fan 14 by screws. Both ends of the energy storage station body 1 are connected to door panels 19 by pins. Safety locks 21 are installed on both the door panels 19 and the outer walls of the energy storage station body 1. Second handles 20 are fixed on the outer walls of both door panels 19. A dustproof plate 6 is inserted into the chassis 3. A mounting plate 9 is fixed to the side of the dustproof plate 6. The mounting plate 9 is fixed to the chassis 3 by bolts 10. A sealing block 7 is fixed to the top of the dustproof plate 6. A first handle 8 is fixed to the top of the sealing block 7. Multiple drainage holes 11 are opened at the bottom of the chassis 3 between the dustproof plate 6 and the inclined plate 4.

[0028] The overall effect of Embodiment 2 is that the operation of the second motor 1601 drives the bidirectional screw 1602 to rotate. Through the cooperation of the connecting block 1603, the moving plate 1604, and the limiting post 1605, the two support plates 12 can be moved in opposite directions, thereby adjusting the position of the two fans 14. The two fans 14 can basically cover the area they are responsible for, which is equivalent to the limitations of the traditional single fan 14 and fixed fan 14. This results in better heat dissipation and greater practicality. With the setting of the two door panels 19, the user can enter through the opening of the two door panels 19. The system enters the main body 1 of the energy storage station to perform maintenance on the electronic components inside. The barrier plate 18 can block the connecting cavity 2 of the main body 1 of the energy storage station from the fan 14, thus preventing the maintenance personnel inside the main body 1 from being accidentally injured when the fan 14 is rotating, which enhances safety. The safety lock 21 can lock the door panel 19. The dustproof plate 6 can prevent dust from entering the air circulation positions of the four chassis 3, greatly reducing the entry of dust. The mounting plate 9 and bolts 10 can be used to install and remove the dustproof plate 6 for easy cleaning and replacement.

[0029] Working Principle: This device divides the space inside the main body 1 of the energy storage station into two parts. With two fans 14, it can simultaneously dissipate heat from both parts of the main body 1, resulting in better heat dissipation. Furthermore, the operation of the second motor 1601 drives the bidirectional screw 1602 to rotate. Through the coordination of the connecting block 1603, the moving plate 1604, and the limiting post 1605, the two support plates 12 can move in opposite directions, thereby adjusting the position of the two fans 14. The two fans 14 can essentially cover their assigned areas, overcoming the limitations of traditional single fans 14 and fixed fans 14. This provides better heat dissipation and greater practicality. Additionally, the device incorporates a sloping plate 4 inside the casing 3, with downward-facing openings 5, effectively preventing dust from entering the machine through the dustproof plate 6. Rainwater inside the housing 3 can be drained through the drainage hole 11, enhancing its practicality. Two doors 19 allow users to access the main body of the energy storage station 1 for maintenance of internal electronic components. A barrier 18 prevents the connection between the main body of the energy storage station 1 and the fan 14, thus preventing accidental injury to maintenance personnel inside the main body of the energy storage station when the fan 14 is running, improving safety. A safety lock 21 locks the doors 19. Dustproof plates 6 prevent dust from entering the four airflow areas of the housing 3. Mounting plates 9 and bolts 10 allow for easy installation and removal of the dustproof plates 6, facilitating cleaning and replacement.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
