Description

Technical Field

[0001] This application relates to the field of battery energy storage cabinet technology, and in particular to a high-utilization industrial and commercial energy storage cabinet. Background Technology

[0002] With the continuous development of industry and commerce, the demand for energy storage equipment is increasing day by day. As the main energy storage carrier, the performance and layout of energy storage cabinets are particularly crucial to meeting the needs of practical applications.

[0003] The existing layout of industrial and commercial energy storage cabinets has obvious defects. Dispersing various systems and equipment reduces the potential mutual interference between them to a certain extent and improves the safety and stability of the system. However, due to the separate arrangement of components, the overall space utilization rate of the product is low, requiring a large floor area. In some special scenarios, such as indoor spaces with limited space or narrow streets, industrial and commercial energy storage cabinets cannot be arranged and placed, which limits their application in more scenarios and makes it difficult to meet the increasingly diversified industrial and commercial energy storage needs. Summary of the Invention

[0004] To improve the space utilization rate inside the commercial and industrial energy storage cabinet and thereby reduce the floor space occupied by the commercial and industrial energy storage cabinet in the installation scenario, a high-utilization commercial and industrial energy storage cabinet is provided.

[0005] The above-mentioned objective of this application is achieved through the following technical solution:

[0006] A high-utilization industrial and commercial energy storage cabinet includes a cabinet body. From bottom to top, the cabinet body has an electrical compartment and a battery compartment. A support frame is provided within the cabinet body, dividing the battery compartment into several stacked battery cavities, each containing a battery pack. The support frame also divides the electrical compartment into several stacked electrical cavities, each containing a PCS module, a high-voltage box module, a circuit breaker module, and a switch module. A first side door and a second side door are hinged to both sides of the cabinet body. The inside of the first side door, facing the battery compartment, has a display and control component electrically connected to the battery pack. The inside of the second side door, facing the battery compartment, has a cooling component.

[0007] By adopting the above technical solution, the electrical compartment and battery compartment are stacked vertically, and the battery compartment and electrical compartment are further divided into multiple chambers using a support frame. The energy storage cabinet has compartments with different functions arranged in layers, and the components are arranged in an orderly manner in the corresponding chambers, making the space utilization more efficient. Each component can be independently slid out for easy maintenance, improving the internal space utilization rate of the commercial and industrial energy storage cabinet, reducing the floor area, and enabling the energy storage cabinet to be placed in more scenarios. The first side door and the second side door are respectively equipped with display and control components and cooling components. The display and control components are integrated inside the first side door for convenient operation and monitoring. The cooling components are located inside the second side door, enhancing the overall practicality and applicability, and improving the space utilization rate inside the energy storage cabinet.

[0008] Preferably, the electrical compartment is provided with a first limiting plate and a second limiting plate on the side near the second side door, which separate the electrical compartment from the cabinet body, and the first limiting plate has several through holes.

[0009] By adopting the above technical solution, the first limiting plate and the second limiting plate are used to restrict the sliding of the PSC module, high voltage box module, switch module and circuit breaker module on the support frame, respectively, to ensure that each module is stably located in the electrical compartment. The perforation allows air circulation between the electrical compartment and the cabinet, so that the cold air generated by the cooling components can be partially applied to the electrical compartment.

[0010] Preferably, the first side door and the second side door have through-holes for heat dissipation facing the electrical compartment. The inner sides of the first side door and the second side door are respectively provided with water-blocking components covering the heat dissipation holes. The water-blocking components include a water-blocking frame and a water-blocking element fixed in the water-blocking frame. The water-blocking element includes a water-blocking plate and a connecting plate. The connecting plate is fixed to the first side door and the second side door respectively. The connecting plate is arranged perpendicular to the vertical direction. The water-blocking plate and the connecting plate are integrally formed, and the included angle between the water-blocking plate and the connecting plate is between 90° and 180°.

[0011] By adopting the above technical solution, the space at the bottom of the first and second side doors is utilized, and heat dissipation holes are opened on the side of the first and second side doors located in the electrical compartment, which can enhance the heat dissipation performance of the electrical compartment. The water-blocking component can prevent water from entering the cabinet through the heat dissipation holes. In rainy environments, rainwater entering the heat dissipation holes will be blocked by the inclined water-blocking plate. After the rainwater accumulates between the side door and the bottom of the water-blocking plate, it will overflow to the outside through the heat dissipation holes, avoiding damage to the internal electrical components due to moisture, and improving the safety and stability of the energy storage cabinet.

[0012] Preferably, a water-blocking plate is also embedded in the water-blocking frame, and the water-blocking plate has ventilation holes distributed in an array.

[0013] By adopting the above technical solution, the baffle can prevent rainwater from entering the cabinet after passing through the baffle plate, and the array of ventilation holes on it can improve air circulation and enhance heat dissipation.

[0014] Preferably, a fixing plate is fixed on the outer wall of the water-blocking frame facing the electrical compartment, and a limiting plate that abuts against the water-blocking plate is rotatably provided inside the fixing plate.

[0015] By adopting the above technical solution, after the baffle plate is embedded in the baffle frame, the limiting plate on the fixed plate can be rotated to make the limiting plate abut against and limit the baffle plate, which can not only limit the baffle plate, but also facilitate the maintenance and replacement of the baffle plate.

[0016] Preferably, a heat dissipation frame is provided on the side of the second side door facing the electrical compartment, and a cooling fan is fixed inside the heat dissipation frame.

[0017] By adopting the above technical solution, the cooling fan can further enhance the heat dissipation effect of the electrical compartment, and can better dissipate heat from each module in the electrical compartment, which helps to improve the performance and reliability of the entire industrial and commercial energy storage cabinet.

[0018] Preferably, a hinged blade is provided between the outer wall of one side of the heat dissipation frame and the outer wall of the water baffle frame to connect the two.

[0019] By adopting the above technical solution, the heat dissipation frame and the water baffle frame are hinged together. After long-term use, the second side door can be opened by rotating it, and the heat dissipation frame can no longer cover the water baffle frame. This facilitates the maintenance of the water baffle plate and water baffle assembly, reduces the blockage of the air holes of the water baffle plate by foreign objects, and ensures the airflow between the water baffle assembly and the cooling fan bracket.

[0020] Preferably, the side of the first side door facing the electrical compartment is provided with a storage component.

[0021] By adopting the above technical solution, the space below the display and control components on the first side door is utilized, and a storage unit is set on the side of the first side door facing the electrical compartment, which can be used to store tools or other related items, further optimizing the functional layout of the energy storage cabinet.

[0022] Preferably, the cabinet has door frames on both sides for the first and second side doors to be embedded and covered. A fixing member is fixed on the bottom of the cabinet. The upper surface of the fixing member is flush with the bottom of the door frame. An adjusting rod is slidably provided on the fixing member in the vertical direction. Both ends of the adjusting rod slide within the fixing member. Several adjusting holes are opened at the bottom of the first and second side doors for the ends of the adjusting rod to be rotatably embedded.

[0023] By adopting the above technical solution, fixing components are installed at the bottom of both sides of the cabinet, and adjusting rods are slidably installed inside the fixing components. The two ends of the adjusting rods can slide up and down, and one end of the adjusting rod can be rotated and inserted into adjusting holes at different positions. After one end of the adjusting rod is inserted into the adjusting hole, the sides of the cabinet are supported by the adjusting rod. Furthermore, the adjustment rod can be rotated and inserted into different adjusting holes to limit the angle of the side doors of the cabinet. Maintenance can be carried out after the side doors of the cabinet are restricted by the adjusting rod, which enhances the flexibility and stability of the energy storage cabinet during maintenance.

[0024] Preferably, the bottom of the door frame is higher than the bottom of the cabinet body in the vertical direction. The bottom of both the first and second side doors is fixed with pressure roller brackets, and the pressure roller brackets are rotatably provided with rollers that abut against the bottom of the doorway.

[0025] By adopting the above technical solution, during the closing process of the first side door, the pressure roller bracket and roller move towards the inside of the energy storage cabinet. During the movement, the roller abuts against the bottom of the cabinet, pushing the roller to move upward and abut against the upper end of the bottom of the cabinet for support. The abutting action between the roller and the bottom of the cabinet supports the first side door after it is closed, preventing the first side door from becoming too heavy and sagging due to the display and control components installed on it. This facilitates the smooth opening and closing of the first side door on the energy storage cabinet.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The cabinet adopts a layered modular design, which divides the interior of the cabinet into upper and lower battery compartments and electrical compartments through the support frame, and further divides them into multiple battery chambers and electrical chambers, so that the battery packs and electrical modules are arranged in an orderly manner. At the same time, the display and control components are integrated on the first side door, and the cooling components are integrated on the second side door, maximizing the use of the cabinet space, making full use of the side door space, avoiding additional occupation of the effective area inside the cabinet, and further optimizing the space layout.

[0028] 2. The synergistic effect of the heat dissipation holes and water-blocking components ensures ventilation and heat dissipation in the electrical compartment while effectively preventing rainwater and dust from entering, thus ensuring stable operation of the equipment in humid or dusty environments.

[0029] 3. A heat dissipation frame is provided on the second side door, facing the electrical compartment from the water-blocking frame. The heat dissipation frame is hinged to the water-blocking frame and a cooling fan is installed inside the heat dissipation frame. The cooling fan can further enhance the heat dissipation effect of the electrical compartment and better dissipate heat from the various modules inside the electrical compartment. After long-term use, after turning and opening the second side door, rotate it so that the heat dissipation frame is no longer covering the water-blocking frame, which facilitates the maintenance of the water-blocking plate and water-blocking components and reduces the blockage of the vent holes of the water-blocking plate by foreign objects.

Detailed implementation method:

[0040] The following section provides a more detailed description, in conjunction with the accompanying diagrams:

[0041] As attached Figure 1 and attached Figure 2As shown, a high-utilization industrial and commercial energy storage cabinet includes a cabinet body 1 and a support frame 2. The cabinet body 1 is the basic support structure of the energy storage cabinet. A first side door 12 and a second side door 13 are respectively hinged on both sides of the cabinet body 1. Here, the first side door 12 is used as the front door for the staff to operate it visually, and the second side door 13 is used as the rear door for heat dissipation.

[0042] The cabinet 1 has a partition 11 that is perpendicular to the first side door 12 and the second side door 13. Above the partition 11, there is a battery compartment 3. Below the partition 11, there is an electrical compartment 4. The support frame 2 includes a support base 21 and a support rod 22. The support rod 22 is set vertically. There are three sets of support rods 22. The three sets of support rods 22 are located on both sides and the middle of the cabinet 1, respectively. There are three support rods 22 in the same set. The three support rods 22 in the same set are located on the side of the cabinet 1 near the first side door 12, the side near the second side door 13, and the middle of the first side door 12 and the second side door 13, respectively.

[0043] The support base 21 is shaped like an angle iron, and several support bases 21 are provided. Each support base 21 is fixed vertically to one side of two sets of supporting vertical rods 22, and is perpendicular to the first side door 12 and the second side door 13. The support bases 21 are evenly spaced vertically, dividing the electrical compartment 4 and the battery compartment 3 into stacked electrical cavities 41 and battery cavities 31, respectively. A replaceable battery pack 32 is slidably installed within the battery cavity 31. The battery pack 32 is the core component of energy storage. Composed of multiple battery cells connected in series or parallel, the battery pack 32 is generally rectangular in shape. When a battery pack 32 malfunctions, it can be easily pulled out for repair or replacement. The electrical cavity 41 is equipped with PCS module 42, high voltage box module 43, circuit breaker module 44 and switch module 45, which are easy to replace. Here, PCS module 42 and high voltage box module 43 are arranged vertically in a set of support rods 22, and circuit breaker module 44 and switch module 45 are arranged vertically in another set of support rods 22.

[0044] As attached Figure 3 and attached Figure 4 As shown, the PCS module 42 and the high-voltage box module 43 are provided with a first limiting plate 46 on the side facing the second side door 13, and the circuit breaker module 44 and the switch module 45 are provided with a second limiting plate 47 on the side facing the second side door 13. The first limiting plate 46 and the second limiting plate 47 are used to limit them, restricting the sliding of the PCS module 42, the high-voltage box module 43, the circuit breaker module 44 and the switch module 45 on the support base 21. The surface of the first limiting plate 46 is also provided with perforations 461 arranged in an array. The perforations 461 can ensure that the rear of the PCS module 42 and the high-voltage box module 43 can be circulated with the outside air.

[0045] PCS module 42, also known as an energy storage converter, is a power conversion module in an energy storage system. It can convert DC to AC or AC to DC. PCS module 42 is typically composed of power semiconductor devices, control circuits, and heat dissipation devices. High voltage box module 43 is used to handle high voltage circuits and contains components such as high voltage fuses and high voltage contactors. Circuit breaker module 44 is used for circuit switching control and overload protection. It is generally composed of contacts, arc extinguishing devices, and operating mechanisms. Switch module 45 is used for switching and selecting control circuits, and is usually a manual switch or an automatic switch.

[0046] As attached Figure 1 and attached Figure 3 As shown, a display and control component 121 is provided on the inner side of the first side door 12. The display and control component 121 is located on one side of the battery compartment 3, and is electrically connected to the battery packs 32 in several battery cavities 31. The display and control component 121 integrates display and control functions. It can display the operating status, power, temperature and other parameters of the battery packs 32 in the energy storage cabinet in real time. The display and control component 121 is generally composed of a display screen, a control panel and control circuit. The display screen can be an LCD screen or a touch screen, which is convenient for operators to view and operate.

[0047] A cooling component 131 is provided on the inner side of the second side door 13. The cooling component 131 is located on the side of the battery compartment 3 away from the first side door 12. The cooling component 131 is used to reduce the temperature at the rear of the battery pack 32 to ensure the normal operation of each battery pack 32. The cooling component 131 can be an air conditioning unit, a cooling fan, etc. The air conditioning unit has a good cooling effect and can accurately control the temperature inside the energy storage cabinet.

[0048] The energy storage cabinet is divided into compartments with different functions, and the components are arranged in an orderly manner in the corresponding chambers, making the space utilization more efficient. Each component can be slid out independently for easy maintenance. The first side door 12 and the second side door 13 are respectively equipped with a display and control component 121 and a cooling component 131. The display and control component 121 provides centralized control, while the cooling component 131 provides targeted cooling, which enhances the overall practicality and applicability.

[0049] As attached Figure 3 and attached Figure 5 As shown, a storage component 122 is provided on the side of the first side door 12 facing the electrical compartment 4. The storage component 122 is a frame structure fixed to the first side door 12. The storage component 122 can facilitate the operation of operators to place some commonly used spare parts or instruction manuals, making the operation more convenient. When maintaining and repairing the energy storage cabinet, the required items can be found quickly, improving work efficiency. At the same time, it also makes the inside of the energy storage cabinet more tidy and orderly, which further enhances the practicality of the energy storage cabinet.

[0050] The cabinet 1 has door frames 15 on both sides for the first side door 12 and the second side door 13 to be embedded and covered. The bottom of the door frame 15 is higher than the bottom of the cabinet 1 in the vertical direction. A fastener 16 is fixed on the bottom of the cabinet 1. The fastener 16 is generally made of metal. Here, there are two fasteners 16. The two fasteners 16 abut against the two door frames 15 respectively, and the upper surfaces of the two fasteners 16 are flush with the bottom of the two door frames 15 respectively.

[0051] An adjusting rod 161 is provided on the upper surface of the fixing member 16. The two ends of the adjusting rod 161 slide up and down in the fixing member 16 respectively, and the middle part of the adjusting rod 161 abuts against the upper surface of the fixing member 16. The bottom of the first side door 12 and the second side door 13 are respectively provided with several adjusting holes 17 for one end of the adjusting rod 161 to be inserted. One end of the adjusting rod 161 can slide up and down in the slide rail, and the other end of the adjusting rod 161 is rotatably inserted into the adjusting hole 17, thereby adjusting the opening position and angle of the first side door 12 and the second side door 13, enhancing the installation flexibility and stability of the energy storage cabinet.

[0052] Pressure roller brackets 9 are fixed to the bottom of the inner sides of the first side door 12 and the second side door 13, respectively. Rollers 91 are rotatably mounted on the bottom of the pressure roller brackets 9 and abut against the bottom of the door frame 15. The rollers 91 are mounted on the pressure roller brackets 9 via shafts. The pressure roller brackets 9 are fixed to the bottom of the first cabinet door by bolts. The rollers 91 abut against the bottom of the door frame 15 and can play an auxiliary sliding role when opening or closing the door, pushing the rollers 91 to move upward and abut against the upper end of the bottom of the door frame 15 for support. The abutting action of the rollers 91 against the bottom of the cabinet 1 supports the first side door 12 after it is closed, preventing the first side door 12 from being too heavy and losing its corner due to the display and control components 121 installed on the first side door 12. This facilitates the smooth opening and closing of the first side door 12 on the energy storage cabinet 1.

[0053] As attached Figure 3 and attached Figure 6 As shown, the first side door 12 and the second side door 13 are located on one side of the electrical compartment 4 and have through heat dissipation holes 14 respectively. The inner side of the first side door 12 and the inner side of the second side door 13 are respectively provided with water-blocking components 6 covering the heat dissipation holes 14. The water-blocking components 6 include water-blocking frames 61 and water-blocking parts 62 fixed in the water-blocking frames 61. The water-blocking frames 61 are rectangular frames, and there are two water-blocking frames 61 here. The two water-blocking frames 61 are respectively fixed to the first side door 12 and the second side door 13 by bolts.

[0054] As attached Figure 6 and attached Figure 7As shown, the water-blocking component 62 includes a water-blocking plate 621 and a connecting plate 622. The water-blocking plate 621 and the connecting plate 622 are integrally formed metal parts. The connecting plate 622 is fixedly connected to the first side door 12 and the second side door 13 respectively. The connecting plate 622 is set perpendicular to the vertical direction, and the included angle between the water-blocking plate 621 and the connecting plate 622 is between 90° and 180°, preferably 135° here. When rainwater falls on the water-blocking plate 621, it will flow through the inclined surface to the connecting plate 622, and then flow to the outside through the heat dissipation hole 14. This ensures normal ventilation and heat dissipation of the heat dissipation hole 14, and prevents water from entering the electrical compartment 4 through the heat dissipation hole 14, reducing the risk of the modules in the electrical compartment 4 coming into contact with rainwater, improving the safety and stability of the energy storage cabinet, and is especially suitable for humid or rainy environments.

[0055] A water baffle plate 63 is also embedded inside the water baffle frame 61. The water baffle plate 63 has an array of ventilation holes 631. The water baffle plate 63 is usually made of thin metal sheet. The ventilation holes 631 on it can be evenly distributed to further filter dust and debris in the air, while also playing a certain role in ventilation.

[0056] The top and bottom of the outer wall of the water-blocking frame 61 facing the electrical compartment 4 are fixed with fixing plates 64. The upper end of the bottom fixing plate 64 of the water-blocking frame 61 is fixed with a limiting plate 65 that abuts against the water-blocking plate 63. The lower end of the top fixing plate 64 of the water-blocking frame 61 is rotatably provided with a limiting plate 65 that abuts against the water-blocking plate 63. Thus, when the water-blocking plate 63 is embedded in the water-blocking frame 61, the limiting plate 65 at the top of the water-blocking frame 61 can be rotated so that the upper and lower limiting plates 65 abut against and limit the water-blocking plate 63. This not only limits the water-blocking plate 63, but also facilitates the maintenance and replacement of the water-blocking plate 63.

[0057] As attached Figure 8 and attached Figure 9 As shown, a heat dissipation frame 7 is provided on the side of the water-blocking frame 61 facing the electrical compartment 4 on the second side door 13. A cooling fan 71 is fixed inside the heat dissipation frame 7. The cooling fan 71 can accelerate the air circulation. The cooling fan 71 is aligned with the first limiting plate 46, thereby accelerating the air circulation between the electrical compartment 4 and the cabinet 1 and improving the heat dissipation effect. A hinge blade 8 is provided between the outer wall of one side of the heat dissipation frame 7 and the outer wall of the water-blocking frame 61 to connect the two. The hinge blade 8 allows the heat dissipation frame 7 to rotate at a certain angle. After long-term use, the rotation will prevent the heat dissipation frame 7 from covering the water-blocking frame 61, which facilitates the maintenance of the water-blocking plate 63 and the water-blocking component 6, reduces the blockage of foreign objects in the vent 631 of the water-blocking plate 63, and ensures the air circulation between the water-blocking component 6 and the cooling fan 71 bracket.

[0058] The implementation effect of this embodiment:

[0059] The cabinet 1 is divided into upper and lower battery compartments 3 and electrical compartments 4 by a support frame 2. Battery compartment 3 is further divided into multiple battery chambers 31, and electrical compartment 4 is divided into multiple electrical chambers 41. This layered modular design allows the battery pack 32 and various electrical modules (such as PCS module 42, high-voltage box module 43, circuit breaker module 44, and switch module 45) to be arranged in an orderly manner, reducing space waste. In addition, the display and control component 121, which is electrically connected to the battery pack 32, is integrated inside the first side door 12 to realize centralized monitoring and operation. Storage components 12 are also provided. 2. Water-blocking component 6, etc.; A cooling component 131 is installed inside the second side door 13, which directly acts on the battery compartment 3 to specifically solve the battery heat dissipation problem. It is also equipped with a water-blocking component 6, a heat dissipation frame 7 and a cooling fan 71, which not only ensures the heat dissipation requirements of the electrical compartment 4, but also effectively prevents rainwater or dust from entering the cabinet, making it suitable for various environmental conditions; It makes full use of idle space and improves the utilization rate of the space inside the energy storage cabinet. The layout of each functional component is compact and does not interfere with each other, enabling the energy storage cabinet to achieve multi-functional integration in a limited space and meet the diverse energy storage needs of industrial and commercial enterprises.
