[0002] With the increasing global demand for renewable energy and growing awareness of environmental protection, photovoltaic (PV) power generation, as a green and clean energy source, is developing rapidly. However, PV power generation is inherently unstable due to factors such as weather and time constraints. To better utilize PV energy, it is converted into a storable form, storing excess energy for unforeseen needs. A PV energy storage control cabinet is a device used in PV power generation systems to store energy, primarily for energy storage and management, thereby improving the reliability and utilization rate of PV power generation.

[0003] In existing technology, control cabinets generate heat during operation, which is dissipated through heat sinks. However, the airflow in these heat sinks is relatively slow, resulting in poor ventilation and heat dissipation. Utility Model Content

[0014] In the first position, the tension of the first elastic element causes the second limiting element to lock the filter element;

[0015] In the second position, the second limiting member overcomes the tension of the first elastic member and releases the lock on the filter element.

[0016] According to the photovoltaic energy storage control cabinet provided by this utility model, the second limiting member includes a connecting block and a limiting block, the connecting block slides in the first sliding groove, and the limiting block is connected to the end of the connecting block away from the air guide component;

[0018] According to the present invention, a photovoltaic energy storage control cabinet further includes a dustproof plate and a second elastic element, and the cabinet body is provided with a second sliding groove.

[0019] The dustproof plate is perpendicular to the connecting block and is located on the side of the first elastic member away from the air guide component. The dustproof plate is slidably disposed in the second groove.

[0020] The second elastic element is located in the second groove and is confined to the side of the dustproof plate away from the connecting block.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0037] The following is combined with Figures 1-5 This invention describes a photovoltaic energy storage control cabinet.

[0038] An embodiment of the first aspect of this utility model provides a photovoltaic energy storage control cabinet, such as... Figure 1 and Figure 3 As shown, the control cabinet includes a cabinet body 1 and a heat dissipation component 22 and a limiting component 23 disposed on the cabinet body 1.

[0039] The cabinet 1 has an installation port on its side; a heat dissipation assembly 22 is located at the installation port, and the heat dissipation assembly 22 includes an air guide component 9, a moisture absorber 11, and a filter 12 arranged in sequence. The air guide component 9 is connected to the inner wall of the cabinet 1, the moisture absorber 11 is located at the installation port, and the filter 12 is located on the side of the moisture absorber 11 away from the air guide component 9; a limiting component 23 is located on the cabinet 1, and the limiting component 23 is adapted to switch between a first position and a second position. In the first position, the limiting component 23 is used to lock the filter 12; in the second position, the limiting component 23 releases the lock on the filter 12.

[0040] It is understandable that an installation port is opened on the cabinet 1 and a heat dissipation component 22 is installed at the installation port. The air guide component 9 of the heat dissipation component 22 can quickly dissipate the heat inside the cabinet 1, thereby achieving rapid cooling of the inside of the cabinet 1, improving the heat dissipation efficiency and performance of the control cabinet, and extending the service life of the control cabinet.

[0041] It should be noted that only the air guide component 9 is installed on the cabinet 1. When the control cabinet is used outdoors and it rains, rainwater will enter the cabinet 1 through the mesh of the air guide component 9, damaging the internal components and reducing its service life. Therefore, this invention effectively blocks dust and other impurities from entering the cabinet 1 through the filter component 12, and the moisture absorber 11 absorbs rainwater to prevent rainwater from entering the cabinet 1, thereby protecting the internal structure of the cabinet 1 from damage, ensuring the normal operation of the equipment, and improving its service life.

[0042] Understandably, the outer wall of the cabinet 1 is also equipped with a limiting component 23. The limiting component 23 locks and unlocks the filter element 12, thereby enabling the installation and removal of the filter element 12 and the moisture-absorbing element 11, which facilitates the cleaning or replacement of the filter element 12 and the moisture-absorbing element 11. It should be noted that cleaning the filter element 12 involves washing away the dust and other impurities it filters, while cleaning the moisture-absorbing element 11 involves removing water from it.

[0043] The photovoltaic energy storage control cabinet provided in this embodiment of the utility model, by setting a heat dissipation component 22 on the cabinet body 1, the air guide component 9 of the heat dissipation component 22 can quickly expel the heat inside the cabinet body 1, thereby achieving rapid cooling and heat dissipation of the cabinet body 1. The moisture-absorbing component 11 and the filter component 12 effectively prevent rainwater, dust and other impurities from entering the cabinet body 1, avoiding damage to the internal structure of the cabinet body 1 and improving its service life. In addition, the filter component 12 is locked and unlocked by the limiting component 23, which realizes the installation and removal of the filter component 12 and the moisture-absorbing component 11, thereby facilitating the removal, cleaning and replacement of the filter component 12 and the moisture-absorbing component 11. The operation is simple and reduces the maintenance difficulty and time cost.

[0044] According to an embodiment of the present invention, the air guide component 9 includes a fan mounting bracket, a fan, and a drive component. The fan mounting bracket is installed on the inner side wall of the cabinet 1 and corresponds to the mounting port position. The drive component is a drive motor, which is installed on the fan mounting bracket, and the fan is fixedly connected to the output shaft of the drive motor.

[0045] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the cabinet 1 has two opposite side walls with installation ports. One of the installation ports has an air guide component 9 that includes an intake fan, and the other installation port has an air guide component 9 that includes an exhaust fan.

[0046] Specifically, the cabinet 1 has two opposing side walls, namely the first side wall and the second side wall. The cabinet 1 has an opening located between the first side wall and the second side wall, and the opening of the cabinet 1 is rotatably connected to the cabinet door 24. Both the first side wall and the second side wall are provided with mounting ports. The mounting port on the first side wall is the first mounting port, and the mounting port on the second side wall is the second mounting port. The first mounting port and the second mounting port are arranged opposite to each other. The fan of the first mounting port is an intake fan, and the fan of the second mounting port is an exhaust fan.

[0047] It is understandable that the intake fan on one side wall of cabinet 1 draws external air into the cabinet 1, and the exhaust fan on the other side wall of cabinet 1 blows the hot air inside the cabinet 1 to the outside, thereby improving the heat dissipation and cooling effect inside cabinet 1.

[0048] It should be noted that the first and second mounting ports on the cabinet 1 can also be multiple, with multiple first mounting ports (and multiple second mounting ports) arranged at intervals along the vertical direction to improve the heat dissipation performance inside the cabinet 1. In this embodiment, for example... Figure 1 As shown, there are two first mounting ports and two second mounting ports.

[0049] Furthermore, such as Figure 1 and Figure 3 As shown, the outer wall of the cabinet 1 has a rain shield 21 located above the heat dissipation assembly 22.

[0050] It is understandable that each mounting port on the cabinet 1 is equipped with a heat dissipation component 22, and the outer wall of the cabinet 1 above each mounting port has a rain shield 21, and the rain shield 21 is located above the heat dissipation component 22.

[0051] Specifically, the filter element 12 is a filter screen, and a bent rain shield 21 is provided above the filter screen. The rain shield 21 is welded and installed on the outside of the cabinet 1. Thus, when it rains, the rain shield 21 blocks some rainwater and prevents it from entering the inside of the filter screen.

[0052] Preferably, cabinet 1 can be made of materials with superior sealing performance and use dustproof and waterproof fans and filters with a higher protection level. In addition, a monitoring system can be used to monitor and automatically adjust the internal temperature and humidity of cabinet 1 in real time, which can also effectively achieve heat dissipation and dustproof and waterproof functions.

[0053] In one embodiment of this utility model, such as Figure 3 As shown, the air guide component 9 has a first limiting component 10 on the side near the moisture absorption component 11. The first limiting component 10 is used to limit the installation of the moisture absorption component 11.

[0054] Specifically, the moisture-absorbing component 11 can be a moisture-absorbing plate, and the first limiting component 10 is a limiting ring set on the fan mounting bracket. The limiting ring is used to limit the installation of the moisture-absorbing plate.

[0055] It is understandable that the fan is located inside the cabinet 1, and a moisture-absorbing plate is located on the side of the fan near the outside of the cabinet 1. A filter screen is located on the outside of the moisture-absorbing plate, and a limiting component 23 is arranged on the outside of the filter screen to position the filter screen, thereby facilitating the installation and removal of the moisture-absorbing plate and the filter screen.

[0056] Furthermore, a water guide groove is provided at the bottom of the moisture-absorbing board to guide the absorbed moisture to the outside of the cabinet 1; of course, a drainage groove communicating with the moisture-absorbing board can also be provided on the outer wall of the cabinet 1, and an absorbent cloth is arranged in the drainage groove to facilitate the drainage of water from the moisture-absorbing board to the outside of the cabinet 1.

[0057] It should be noted that the moisture-absorbing board has good regeneration capabilities, meaning that it can release the absorbed moisture and maintain its performance in low-humidity environments.

[0058] In one embodiment of this utility model, such as Figure 1 As shown, the photovoltaic energy storage control cabinet also includes components installed in the cabinet 1; the components include the photovoltaic energy storage unit 4, the single-pole double-throw switch 7, the terminal block 8, the power supply unit 5, and the relay 6.

[0059] Specifically, the integrated photovoltaic and energy storage unit 4 is installed inside the cabinet 1; above the integrated photovoltaic and energy storage unit 4, there is a horizontal array of single-pole double-throw switches 7, which are used to control the automatic switching connection of the switch; above the single-pole double-throw switches 7 and on one side of the integrated photovoltaic and energy storage unit 4, there are wiring terminals 8 arranged in an array; on one side of the single-pole double-throw switches 7, there are power supply devices 5 and relays 6.

[0060] It should be noted that terminal 8 is used to connect to mains power, power supply, important loads and secondary loads, and photovoltaic-storage integrated unit 4 is connected to external photovoltaic devices through wires.

[0061] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a mounting plate 3 is provided inside the cabinet 1. A heat dissipation cavity is formed between the mounting plate 3 and the side wall of the cabinet 1 away from the outlet, and the mounting port corresponds to the heat dissipation cavity.

[0062] Optionally, a mounting bracket 2 is installed inside the cabinet 1. A mounting plate 3 is installed on the side of the mounting bracket 2 near the outlet of the cabinet 1. The side of the mounting plate 3 away from the opening of the cabinet 1 forms a heat dissipation cavity with the inside of the cabinet 1. A fan is installed in the heat dissipation cavity formed between the mounting plate 3 and the cabinet 1.

[0063] Specifically, the mounting plate 3 is mounted on the mounting bracket 2 with screws, and the mounting bracket 2 is welded to the inside of the cabinet 1. The integrated optical storage unit 4, the single-pole double-throw switch 7, the terminal block 8, the power supply unit 5, and the relay 6 are all mounted on the mounting plate 3.

[0064] Preferably, the mounting plate 3 is made of a thermally conductive material. The mounting plate 3 quickly transfers the heat of the components to the heat dissipation cavity to improve the heat dissipation efficiency of the components inside the cabinet 1.

[0065] In one embodiment of this utility model, such as Figure 1 , Figure 4 and Figure 5As shown, the outer wall of the cabinet 1 is provided with a first sliding groove 16 located outside the mounting opening; the limiting component 23 includes a limiting member, which includes a second limiting member 25 and a first elastic member 15. The second limiting member 25 is slidably disposed in the first sliding groove 16, and the first elastic member 15 is disposed in the first sliding groove 16 and limited to the side of the second limiting member 25 away from the mounting opening; in the first position, the tension of the first elastic member 15 causes the second limiting member 25 to lock the filter element 12; in the second position, the second limiting member 25 overcomes the tension of the first elastic member 15 and releases the lock on the filter element 12.

[0066] Understandably, the second limiting member 25 is slidably disposed in the first slide groove 16. The second limiting member 25 is adapted to slide between the first position and the second position. In the first position, the tension of the first elastic member 15 causes the second limiting member 25 to approach the filter element 12 and abut against the filter element 12, thereby limiting the filter element 12. In the second position, the second limiting member 25 overcomes the tension of the first elastic member 15 and moves away from the filter element 12, thereby releasing the locking of the filter element 12 and allowing the filter element 12 and the moisture-absorbing member 11 to be disassembled.

[0067] For example, the second limiting member 25 includes a connecting block 14 and a limiting block 13. The connecting block 14 slides in the first groove 16, and the limiting block 13 is connected to the end of the connecting block 14 away from the air guide member 9. In the first position, the connecting block 14 abuts against the outer wall of the filter member 12, and the limiting block 13 abuts against the side of the filter member 12 away from the moisture-absorbing member 11.

[0068] Specifically, a connecting block 14 is installed on the side of the limiting block 13 near the cabinet 1. The connecting block 14 is slidably connected to the first slide groove 16. A first elastic element 15 is installed on the side of the connecting block 14 away from the filter element 12. The first elastic element 15 is installed in the first slide groove 16.

[0069] In this embodiment, the limiting block 13 and the connecting block 14 are welded together. The first elastic element 15 is a spring. The two ends of the first elastic element 15 are welded to one end of the connecting block 14 and the side wall of the first slide groove 16 away from the installation port, respectively. The limiting block 13 and the connecting block 14 are limited by the first elastic element 15, thereby limiting the installation of the filter element 12 and the moisture-absorbing element 11.

[0070] Furthermore, the limiting component 23 includes a dustproof component, which includes a dustproof plate 17 and a second elastic member 18. The cabinet 1 is provided with a second slide groove 19. The dustproof plate 17 is perpendicular to the connecting block 14 and is located on the side of the first elastic member 15 away from the air guide component 9. The dustproof plate 17 is slidably disposed in the second slide groove 19. The second elastic member 18 is located in the second slide groove 19 and is limited to the side of the dustproof plate 17 away from the connecting block 14.

[0071] Specifically, the second slide groove 19 is located outside the first slide groove 16. One end of the movable plate is perpendicularly abutting against the limiting block 13, and the other end of the movable plate is equipped with a second elastic element 18. The second elastic element 18 adopts a spring structure. The movable plate is slidably connected to the second slide groove 19, and the second elastic element 18 is installed in the second slide groove 19.

[0072] In this embodiment, the two ends of the second elastic member 18 are welded to one end of the movable plate and the side wall of the second slide groove 19 away from the installation port, respectively.

[0073] In one embodiment of this utility model, the limiting block 13 is provided with a gripping part 20, which facilitates gripping the limiting block 13 to realize the second limiting member 25 switching from the first position to the second position; for example, the gripping part 20 can be a protrusion provided on the limiting block 13, of course, in other embodiments, the gripping part 20 can also be a groove.

[0074] It should be noted that a gripping part 20 can also be provided on the dustproof plate 17 to facilitate the installation and movement of the dustproof plate 17.

[0075] In this embodiment, the limiting block 13 and its protrusions are integrally formed, and the movable plate and its protrusions are integrally formed. The first slide groove 16 and the second slide groove 19 are both formed on the side wall of the cabinet 1. The width of the second slide groove 19 is greater than the width of the first slide groove 16. By designing the width of the second slide groove 19 to be greater than the width of the first slide groove 16, it is convenient for the movable plate to move with the movement of the limiting block 13. The second elastic member 18 is used to squeeze the movable plate, so that the movable plate shields and protects the inside of the first slide groove 16, preventing dust from entering the inside of the first slide groove 16 and causing the problem of difficulty in cleaning.

[0076] In one embodiment of the present invention, a plurality of limiting components 23 are arranged on the outer side of each filter element 12 at each mounting port, thereby locking and unlocking a filter element 12 by means of the plurality of limiting components 23.

[0077] For example, the filter element 12 is quadrilateral, with two limiting components 23 located on opposite sides of the filter element 12. The second limiting members 25 of the two limiting components 23 are brought close together to clamp and lock the filter element 12; conversely, the second limiting members 25 of the two limiting components 23 are moved away to release the clamping and locking of the filter element 12. It should be noted that limiting components 23 can also be provided on all four sides of the filter element 12, so that locking and unlocking of the filter element 12 can be achieved through four limiting components 23.

[0078] Optionally, a limiting component 23 is arranged on the outer side of one corner of the filter element 12, and connecting components are arranged on the outer sides of the other three corners of the filter element 12. The connecting components are connected to the cabinet 1 and form positioning grooves that mate with the corners of the filter element 12. The three connecting components position the three corners of the filter element 12, and the limiting component 23 can lock and unlock the filter element 12. It should be noted that the limiting component mates with the corners of the filter screen to limit the corners of the filter screen, and the dustproof component is in active contact with the limiting component.

[0079] It should be noted that the movement range of the filter screen is limited by the connecting component and the limiting component 23 to prevent it from shifting due to vibration, airflow, or other factors during outdoor use. This ensures that the filter screen always remains in its designed position, guaranteeing its sealing performance and filtration efficiency. Furthermore, when replacing the filter screen, operators do not need to consider its displacement or positioning; the connecting component and the limiting component 23 are sufficient to locate the filter screen.

[0080] Preferably, limit components 23 are arranged on the outer sides of the four corners of the filter element 12. The filter element can be disassembled and installed by operating the second limit component 25 of any limit component 23 to switch between the first position and the second position.

[0081] The working principle of this utility model is as follows: When in use, the integrated optical storage unit 4, single-pole double-throw switch 7, terminal block 8, power supply device 5 and relay 6 are connected by wires and connected to an external device, and can be controlled and operated through the integrated optical storage unit 4.

[0082] During operation, heat is transferred to the heat dissipation cavity through the mounting plate 3. The intake fan on one side of the cabinet 1 blows external air into the heat dissipation cavity, and the exhaust fan on the other side of the cabinet 1 blows the hot air inside the heat dissipation cavity to the outside, thereby achieving the function of heat dissipation and cooling.

[0083] The air entering and exiting the heat dissipation cavity will be filtered and dehumidified by the corresponding filter element 12 and moisture absorber 11. In the event of rain, the rain shield 21 can block some rainwater, preventing rainwater from entering the inside of the filter element 12 and preventing the moisture absorber 11 from failing to absorb moisture in time, which would cause some rainwater to enter the cabinet 1 and affect the normal use of the internal structure.

[0084] When it is necessary to disassemble, clean, or replace the moisture-absorbing component 11 and the filter component 12, the limiting block 13 is moved away from the filter component 12 by the protrusion on the limiting block 13. The connecting block 14 moves in the first slide groove 16, the first elastic element 15 is compressed, and at the same time the limiting block 13 presses the movable plate. The movable plate moves in the second slide groove 19, the second elastic element 18 is compressed, and the positioning lock of the limiting block 13 on the filter component 12 is released, so that the filter component 12 and the moisture-absorbing component 11 can be disassembled, cleaned, or replaced. After replacement, the limiting block 13 is released, the first elastic element 15 drives the limiting block 13 to reset, the filter component 12 is positioned and locked, and at the same time, the second elastic element 18 drives the movable plate to limit and cover the first slide groove 16 to prevent dust.

[0085] The photovoltaic energy storage control cabinet provided in this embodiment of the utility model can dissipate heat through a fan while preventing rainwater and dust from entering the cabinet 1 through the filter element 12 and the moisture-absorbing element 11, thus avoiding damage to the internal structure and ensuring stable operation under complex climatic conditions. This reduces the failure rate and extends the overall service life, while also providing users with a more economical and efficient user experience. Furthermore, it facilitates the disassembly, cleaning, or replacement of the filter and moisture-absorbing plate, making operation simple, convenient, and effectively reducing maintenance difficulty.

[0086] A second aspect of this utility model provides a photovoltaic power generation system, which includes the photovoltaic energy storage control cabinet provided in any of the above embodiments.
