Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, specifically to an energy storage AC power distribution cabinet. Background Technology

[0002] With the rapid development of energy storage technology, AC energy storage distribution cabinets are increasingly widely used in industrial and commercial energy storage, microgrids, and distributed energy systems. However, AC energy storage distribution cabinets face the challenge of controlling the operating temperature of the equipment under seasonal temperature variations. In high-temperature environments, excessively high internal temperatures may damage internal equipment and reduce its service life; while in low-temperature environments, the energy storage efficiency of the battery will be affected, requiring measures to ensure the normal operation of the battery.

[0003] However, in existing technologies, the number of ventilation holes in energy storage cabinets is fixed and cannot be dynamically adjusted according to changes in external temperature, which limits their temperature control effectiveness in different seasons. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an energy storage AC power distribution cabinet. The lifting shell is driven to move up and down in the lifting groove at the top of the cabinet by an electric push rod, which facilitates the control of multiple or single sets of air inlets and outlets for air intake and exhaust, and facilitates the control of the gas flow inside the cabinet. In conjunction with the heating plate, it can further ensure that the temperature inside the cabinet can be effectively controlled, and ensure that the battery pack units or other equipment inside the cabinet are at the optimal operating temperature.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An energy storage AC power distribution cabinet includes a cabinet body, a lifting groove at the top of the cabinet body, a lifting shell inside the lifting groove, a cabinet door at the front of the cabinet body, multiple air inlets at the bottom of the left and right sides of the cabinet body, multiple exhaust holes on the left and right sides of the lifting shell, sliding grooves communicating with the lifting groove on the left and right sides of the cabinet body, a baffle plate connected to the bottom of the lifting shell inside the sliding groove, the baffle plate being able to block multiple sets of air inlets, multiple partitions inside the cabinet body, ventilation holes on the partitions, heating plates on the left and right sides inside the cabinet body, a lifting device at the top of the cabinet body, and a temperature sensor inside the cabinet body.

[0007] Preferably, the lifting device includes an electric actuator, which is mounted on the upper part of the cabinet, and the power output end of the electric actuator is connected to the top of the lifting shell.

[0008] Preferably, the mounting bracket is equipped with a fan, and the bottom of the mounting bracket is equipped with a motor to drive the fan.

[0009] Preferably, the cabinet has an internal insulation layer made of rock wool.

[0010] Preferably, both the air inlet and the air outlet are equipped with filters.

[0011] Preferably, the partition divides the interior of the cabinet into multiple installation compartments, with a battery pack unit installed on the bottom partition, and the heating plate is located on the cabinet on both sides of the battery pack unit.

[0012] Preferably, the top of the lifting shell is provided with a rain shelter, and the bottom of the cabinet is provided with support legs.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model has a simple structure. The electric push rod drives the lifting shell to move up and down in the lifting groove at the top of the cabinet, which facilitates the control of multiple or single sets of air inlets and outlets for air intake and exhaust, and facilitates the control of the gas flow inside the cabinet. In conjunction with the heating plate, it can further ensure that the temperature inside the cabinet can be effectively controlled, and ensure that the battery pack or other equipment inside the cabinet is at the optimal working temperature.

[0015] 2. This device uses a motor to drive the fan on the mounting bracket to rotate, which increases the speed of gas flow inside the cabinet and ensures that the gas inside the cabinet is quickly discharged from the exhaust port. As the gas inside the cabinet is quickly discharged from the exhaust port, a negative pressure will be formed inside the cabinet, which will facilitate the entry of external gas into the cabinet from the air inlet at the bottom of the cabinet.

[0016] 3. This device reduces heat transfer between the cabinet's interior and the external environment by installing an insulation layer, ensuring stable internal temperature. In the event of a fire, the rock wool insulation layer provides heat insulation and flame retardancy, preventing the fire from spreading.

[0017] 4. The filter screen of this device can effectively block dust and particulate matter in the air, preventing them from entering the cabinet. Excessive dust covering electrical components can not only affect heat dissipation but also lead to excessive static current, increasing the risk of electric shock. The filter screen can also prevent rainwater from entering the cabinet through the air inlet and outlet, thus protecting the internal components from the effects of a humid environment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] An energy storage AC power distribution cabinet, with the following structure: Figures 1-5 As shown, the cabinet includes a cabinet body 1. The top of the cabinet body 1 has a lifting groove 11, within which a lifting shell 10 is housed. The front of the cabinet body 1 has a cabinet door 18. The bottom of the left and right sides of the cabinet body 1 has multiple layers of air inlets 4. The left and right sides of the lifting shell 10 have multiple layers of exhaust holes 3. The left and right sides of the cabinet body 1 have sliding grooves 14 communicating with the lifting groove 11. The sliding grooves 14 have baffles 15 connected to the bottom of the lifting shell 10, which can block multiple sets of air inlets. The cabinet body 1 has multiple partitions 12 inside, with ventilation holes 13 on each partition. Heating plates 17 are located on the left and right sides inside the cabinet body 1. A lifting device is located at the top of the cabinet body 1. A temperature sensor 9 is located inside the cabinet body 1. The partitions 12 divide the interior of the cabinet body 1 into multiple installation compartments. A battery pack unit is installed on the bottommost partition 12. The heating plates 17 are located on the cabinet body 1 on both sides of the battery pack unit. The lifting device includes an electric push rod 8, which is mounted on the upper part of the cabinet 1 via a mounting bracket 5. The power output end of the electric push rod 8 is connected to the top of the lifting shell 10.

[0027] The cabinet 1 is divided into multiple installation compartments by partition 12. Each installation compartment contains a battery pack unit, an energy storage converter, a battery management system, a control unit, and power distribution equipment. The battery pack unit is installed on the bottom partition 12. The space between the bottom partition 12 and the bottom of the cabinet 1 is a partition compartment. Air inlets 4 are located on the cabinet 1 on both sides of the partition compartment, and exhaust outlets 3 are located on the left and right sides of the lifting shell 10. Both air inlets 4 and exhaust outlets 3 are multi-layered. The partition 12 is provided with ventilation holes 13 to facilitate the free flow of gas inside the cabinet 1.

[0028] When the external temperature is high, the temperature of the battery pack unit and other equipment inside the cabinet 1 will rise during operation. The temperature sensor 9 senses the temperature inside the cabinet 1 and sends a signal to the control unit. The control unit then controls the electric push rod 8 to start. The power output end of the electric push rod 8 drives the lifting shell 10 to move upward. The lifting shell 10 will then extend upward from the lifting groove 11 at the top of the cabinet 1. The exhaust holes 3 on both sides of the lifting shell 10 will be exposed in multiple layers. As the lifting shell 10 rises, the baffle 15 connected to the lifting shell 10 moves upward with it. The air inlets 4 on both sides of the bottom of the cabinet 1 will change from the original single-layer air inlet to multi-layer air inlet. Through the multi-layer air inlet 4 and the multi-layer exhaust 3, the air flow inside the cabinet 1 is increased, thereby expelling more heat from the cabinet 1 through the exhaust holes 3, thus achieving cooling of the inside of the cabinet 1.

[0029] When the external temperature is low, in order to ensure the capacity of the battery pack unit (the capacity of the battery pack unit will decrease when the temperature is low), when the temperature sensor 9 senses that the internal temperature of the cabinet 1 has decreased and will affect the battery capacity, the temperature sensor 9 sends a signal to the control unit. The control unit then controls the electric push rod 8 to start. The power output end of the electric push rod 8 drives the lifting shell 10 to retract and descend into the lifting groove 11. The multi-layer exhaust holes 3 on both sides of the lifting shell 10, which were originally used for exhaust, retract and descend into the lifting groove 11 layer by layer, and become single-layer exhaust holes 3 for exhaust. Meanwhile, the baffle plate 15 at the bottom of the lifting shell 10 moves down synchronously with the lifting shell 10. The baffle plate 15 blocks the multi-layer air intake holes 4, which were originally used for air intake, and turns the multi-layer air intake holes 4 into single-layer air intake holes 4, reducing the gas flow of the cabinet 1. At the same time, the control unit controls the heating plate 17 to heat the battery pack unit, further increasing the temperature inside the cabinet 1, and ensuring that the capacity of the battery pack unit is kept at the optimal state.

[0030] The mounting bracket 5 is equipped with a fan 6, and the bottom of the mounting bracket 5 is equipped with a motor 7 that drives the fan 6.

[0031] The motor 7 drives the fan 6 on the mounting bracket 5 to rotate, increasing the speed of gas flow inside the cabinet 1 and ensuring that the gas inside the cabinet 1 is quickly discharged from the exhaust port 3. As the gas inside the cabinet 1 is quickly discharged from the exhaust port 3, a negative pressure is formed inside the cabinet 1, which facilitates the entry of external gas into the cabinet 1 from the air inlet at the bottom of the cabinet 1.

[0032] The cabinet 1 has an internal insulation layer made of rock wool.

[0033] By setting up an insulation layer, heat transfer between the inside of cabinet 1 and the external environment can be reduced, ensuring the stability of the internal temperature of cabinet 1. In the event of a fire, the rock wool insulation layer can play a role in heat insulation and flame retardancy, preventing the spread of fire.

[0034] Both the air inlet 4 and the exhaust outlet 3 are equipped with filters.

[0035] The filter effectively blocks dust and particulate matter from the air, preventing them from entering the cabinet. Excessive dust covering electrical components not only affects heat dissipation but can also lead to excessive static current, increasing the risk of electric shock.

[0036] Example 2

[0037] Based on Embodiment 1, the top of the lifting shell 10 is provided with a rain shelter 2, and the bottom of the cabinet 1 is provided with a support leg 16.

[0038] The rain shelter 2 effectively prevents rainwater from falling directly onto the top of the distribution cabinet, while also preventing rainwater from seeping into the cabinet 1 through the vent 3 or other gaps. This is especially important for outdoor energy storage distribution cabinets, as rainwater infiltration can lead to short circuits, equipment damage, or even safety accidents. Since filters are also installed at the air inlet 4 and vent 3, these filters also prevent rainwater from entering the cabinet 1 through these openings, thus protecting the internal components from the effects of a humid environment. The support feet 16 at the bottom of the cabinet 1 can raise the distribution cabinet, preventing ground moisture from directly contacting the cabinet 1 and reducing equipment damage caused by a humid environment. By reducing the impact of moisture on the equipment, the service life of the energy storage distribution cabinet can be effectively extended.

[0039] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations, additions, subtractions, or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
