Description

Technical Field

[0001] This utility model relates to an energy storage device, specifically a combined photovoltaic energy storage cabinet. Background Technology

[0002] A photovoltaic (PV) energy storage cabinet is an energy storage device used in a photovoltaic (PV) power generation system. It is mainly used to store the electrical energy generated by solar panels (PV panels) and release the stored electrical energy for users when needed. It plays an important role in modern energy systems, especially in distributed PV power generation systems. A modular PV energy storage cabinet is a modularly designed energy storage device mainly used for energy storage and management in PV power generation systems. It installs different functional components into independent cabinets and allows these cabinets to be flexibly combined to meet the needs of different users.

[0003] During the use of modular photovoltaic energy storage cabinets, a large amount of heat is generated during operation because many devices are installed inside the cabinet. To ensure that the equipment can operate stably and for a long time, it is crucial to effectively dissipate heat from the space inside the cabinet. However, in common modular photovoltaic energy storage cabinet designs, the heat dissipation holes are usually fixed in specific locations within the cabinet. This fixed layout of heat dissipation holes has certain limitations, resulting in uneven temperature distribution within the cabinet space with significant differences. Specifically, heat often concentrates in a specific area of ​​the cabinet and cannot be effectively dissipated or evenly distributed. Utility Model Content

[0004] The purpose of this invention is to provide a modular photovoltaic energy storage cabinet to solve the problems mentioned in the background art.

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

[0006] A modular photovoltaic energy storage cabinet includes a cabinet body, symmetrically arranged heat dissipation holes on both sides of the cabinet body, and a cabinet door rotatably mounted on the cabinet body. A heat dissipation structure is provided on the cabinet body at the locations of the heat dissipation holes, and the heat dissipation structure includes:

[0007] A lifting transmission component installed on the cabinet and a protective ring that can be reciprocated and lifted on the lifting transmission component, wherein a fan connected to the lifting transmission component is rotatably mounted on the protective ring.

[0008] It also includes multiple sealing plates with their edges fitted and slidably mounted on the cabinet at the heat dissipation hole location. When the protective ring is raised or lowered, it can control the sealing plate at the corresponding position to slide so that the slots on the sealing plate are aligned and connected with the heat dissipation hole.

[0009] As described above, a combined photovoltaic energy storage cabinet has a first bevel gear fixedly installed on one side of the center of the fan, and the first bevel gear is rotatably mounted on the protective ring.

[0010] As described above, a combined photovoltaic energy storage cabinet: the first bevel gear meshes with a second bevel gear rotatably mounted on a rotating disk fixed on the protective ring;

[0011] The second bevel gear has a insertion hole at its center, and the inner wall of the insertion hole is provided with multiple anti-rotation protrusions.

[0012] As described above, a modular photovoltaic energy storage cabinet has symmetrically arranged abutment blocks on both sides of the protective ring, and the abutment blocks are provided with connection holes.

[0013] As described above, a modular photovoltaic energy storage cabinet includes a lifting transmission component comprising a transmission mechanism mounted on the cabinet body and a reciprocating lifting mechanism connected to the transmission mechanism.

[0014] The transmission mechanism includes a motor mounted on the cabinet, a second gear disposed on the output shaft of the motor, and a transmission shaft fixed to the center of the second gear. One end of the transmission shaft rotates on the cabinet, and the transmission shaft is slidably inserted into the insertion hole. An anti-rotation groove is provided on the transmission shaft to cooperate with the anti-rotation protrusion.

[0015] As described above, a combined photovoltaic energy storage cabinet includes a reciprocating lifting mechanism comprising a first gear meshing with the second gear and a reciprocating lead screw mounted on the first gear, one end of which rotates on the cabinet body.

[0016] The reciprocating lead screw is connected to the connecting pin that is fitted inside the connecting hole.

[0017] As described above, a modular photovoltaic energy storage cabinet is provided with a sealing plate slidably connected to the cabinet body, and an anti-rebound component is provided on one side of the sealing plate.

[0018] As described above, a combined photovoltaic energy storage cabinet includes an L-shaped block disposed at one end of the sealing plate, an abutment pin disposed on the L-shaped block parallel to the sealing plate, and a spring disposed on the L-shaped block away from the abutment pin.

[0019] One end of the spring abuts against the L-shaped block, and the other end abuts against the cabinet body. The abutting pin cooperates with the abutting block to abut.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] By designing a heat dissipation structure at the ventilation holes on the cabinet, uniform and efficient heat dissipation can be achieved within the cabinet's interior, significantly improving heat dissipation efficiency. Specifically, driven precisely by the lifting transmission mechanism, the fan can rotate flexibly on the protective ring, generating a blowing effect that brings continuous airflow to the cabinet interior, carrying away heat. Simultaneously, the protective ring itself has the function of reciprocating up and down sliding on the lifting transmission mechanism. This allows the fan to not only blow air in a fixed position but also move flexibly at different heights within the cabinet, achieving all-round, multi-layered airflow for heat dissipation. This ensures that all areas inside the cabinet receive sufficient cooling. Furthermore, when the protective ring moves to different heights, it can abut against and push the sealing plate, causing it to move accordingly. This allows the slots on the sealing plate to precisely align and connect with the ventilation holes. When the fan blows air, air can flow smoothly through these connected holes, forming good air convection, further enhancing heat dissipation efficiency and effectively preventing excessive heat accumulation in localized areas.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Please see Figures 1-5 In this embodiment of the present invention, a combined photovoltaic energy storage cabinet includes a cabinet body 1, heat dissipation holes 2 symmetrically opened on both sides of the cabinet body 1, and a cabinet door 3 rotatably mounted on the cabinet body 1. A heat dissipation structure is provided on the cabinet body 1 at the location of the heat dissipation holes 2, and the heat dissipation structure includes:

[0034] A lifting transmission component installed on the cabinet 1 and a protective ring 4 reciprocally mounted on the lifting transmission component, wherein a fan 5 connected to the lifting transmission component is rotatably mounted on the protective ring 4;

[0035] It also includes multiple sealing plates 16 that are fitted to the edges and slidably installed on the cabinet 1 at the heat dissipation hole 2. When the protective ring 4 is raised or lowered, it can control the sealing plate 16 at the corresponding position to slide so that the slots opened on the sealing plate 16 are aligned and connected with the heat dissipation hole 2.

[0036] In this embodiment, when the equipment inside the cabinet 1 generates heat during operation and needs to dissipate heat, the protective ring 4 can fit tightly against the cabinet 1 through the precise movement of the lifting transmission component, and reciprocate up and down movement on the lifting transmission component. During this process, the fan 5 rotatably connected to the protective ring 4 can rotate flexibly on the protective ring 4 under the drive of the lifting transmission component. The rotating fan 5 generates a strong blowing effect, which promotes the airflow inside the cabinet 1, thereby achieving effective heat dissipation.

[0037] As the protective ring 4 rises and falls to different heights, it can precisely abut against the corresponding sealing plate 16. This abutment causes the sealing plate 16 to slide on the cabinet 1, thereby aligning and connecting the slots on the sealing plate 16 with the heat dissipation holes 2. This design ensures that when the fan 5 blows air, the air can flow smoothly through these connected holes, further enhancing the heat dissipation effect, meeting the heat dissipation needs of the equipment, and ensuring the stable operation of the equipment inside the cabinet 1.

[0038] Please see Figure 5 and Figure 6 As a further embodiment of this utility model, a first bevel gear 6 is fixedly installed on one side of the center of the fan 5, and the first bevel gear 6 is rotatably mounted on the protective ring 4.

[0039] The first bevel gear 6 meshes with the second bevel gear 7 rotatably mounted on the rotating disk 8 fixed on the protective ring 4;

[0040] The second bevel gear 7 has a insertion hole at its center, and the inner wall of the insertion hole is provided with multiple anti-rotation protrusions.

[0041] The protective ring 4 is symmetrically provided with abutment blocks 9 on both sides, and the abutment blocks 9 are provided with connection holes 10.

[0042] In this embodiment, the fan 5 is rotatably mounted on the protective ring 4. The first bevel gear 6 fixed on the fan 5 is tightly meshed with the second bevel gear 7. When the second bevel gear 7 rotates, it can drive the fan 5 to rotate on the protective ring 4 through its meshing relationship with the first bevel gear 6. This rotation mechanism not only ensures the stable operation of the fan 5, but also effectively realizes the function of blowing air for heat dissipation.

[0043] The second bevel gear 7 and the rotating disk 8 cooperate with each other through a rotatable connection. The rotating disk 8 can ensure that the second bevel gear 7 is always kept in a fixed position on the protective ring 4 for rotational adjustment. The protective ring 4 is cleverly provided with abutment blocks 9 on both sides. These abutment blocks 9 play an important supporting and connecting role in the structure of the protective ring 4. Connection holes 10 are opened at the abutment blocks 9. The design of these connection holes 10 not only takes into account the stability of the structure, but also fully meets the reciprocating lifting and lowering requirements of the protective ring 4 in the lifting transmission component. Through these connection holes 10, the protective ring 4 can achieve precise connection and stable transmission with the lifting transmission component.

[0044] Please see Figure 5 and Figure 7 As a further embodiment of this utility model, the lifting transmission component includes a transmission mechanism disposed on the cabinet 1 and a reciprocating lifting mechanism connected to the transmission mechanism.

[0045] The transmission mechanism includes a motor 15 mounted on the cabinet 1, a second gear 13 disposed on the output shaft of the motor 15, and a transmission shaft 14 fixed at the center of the second gear 13. One end of the transmission shaft 14 rotates on the cabinet 1, and the transmission shaft 14 is slidably inserted into the insertion hole. An anti-rotation groove is provided on the transmission shaft 14 in cooperation with the anti-rotation protrusion.

[0046] The reciprocating lifting mechanism includes a first gear 12 that meshes with the second gear 13 and a reciprocating lead screw 11 disposed on the first gear 12. One end of the reciprocating lead screw 11 rotates on the cabinet 1.

[0047] The reciprocating lead screw 11 is connected to the connecting pin that is fitted inside the connecting hole 10.

[0048] In this embodiment, the reciprocating lead screw 11 is tightly connected to the connecting pin in the connecting hole 10. Since the protective ring 4 is symmetrically provided with abutment blocks 9 on both sides, and each abutment block 9 is provided with a connecting hole 10, these two connecting holes 10 are respectively connected to the two reciprocating lead screws 11. This design allows the protective ring 4 to be reciprocated and moved up and down on the reciprocating lead screw 11 through the connecting pin when the reciprocating lead screw 11 rotates, thereby realizing the flexible adjustment of the position of the protective ring 4.

[0049] A first gear 12 is provided on the reciprocating screw 11, and the first gear 12 meshes with the second gear 13. It is worth noting that the diameter of the first gear 12 is larger than the diameter of the second gear 13. This difference in diameter results in a different gear ratio. That is, when the second gear 13 rotates for many revolutions, the first gear 12 can rotate one revolution. Through this gear ratio design, when the drive shaft 14 rotates for many revolutions, the reciprocating screw 11 rotates one revolution. This transmission mechanism can not only achieve precise lifting and lowering adjustment, but also effectively reduce the transmission speed, so that the protective ring 4 can be slowly adjusted in the efficient rotation of the fan 5.

[0050] An anti-rotation groove is provided on the drive shaft 14 in conjunction with the anti-rotation protrusion. The cooperation between the anti-rotation protrusion and the anti-rotation groove plays a key role in transmission. When the drive shaft 14 rotates, the interaction between the anti-rotation protrusion and the anti-rotation groove can drive the second bevel gear 7 to rotate. Moreover, even when the drive shaft 14 is in a lifting and sliding state, this cooperation mechanism can still ensure that the drive shaft 14 drives the second bevel gear 7 to rotate, thereby meeting the needs of lifting and lowering.

[0051] Please see Figure 8 and Figure 9 As a further embodiment of this utility model, the sealing plate 16 is slidably connected to the cabinet 1, and an anti-rebound component is provided on one side of the sealing plate 16.

[0052] The abutment rebound assembly includes an L-shaped block 17 disposed at one end of the sealing plate 16, an abutment pin 18 disposed on the L-shaped block 17 parallel to the sealing plate 16, and a spring 19 disposed on the L-shaped block 17 away from the abutment pin 18.

[0053] One end of the spring 19 abuts against the L-shaped block 17, and the other end abuts against the cabinet 1. The abutting pin 18 cooperates with the abutting block 9 to abut.

[0054] In this embodiment, in the initial state, the abutting pin 18 is not resisted by the abutting block 9. At this time, the slots and heat dissipation holes 2 on the sealing plate 16 are misaligned. Due to this misalignment, air cannot flow between the two, thus effectively preventing the entry of external air and maintaining the relative sealing of the cabinet 1. This design can effectively prevent dust and other impurities from entering the cabinet 1 when heat dissipation is not required, protecting the internal equipment from contamination.

[0055] However, the situation changes when the abutting pin 18 is abutted by the abutting block 9. This abutting action causes the L-shaped block 17 and the sealing plate 16 to slide along the preset track. During the sliding process, the spring 19 is compressed and contracts. Although the spring 19 is compressed, it always maintains a rebound force. This force allows the sealing plate 16 to move smoothly when the abutting pin 18 is abutted. As the sealing plate 16 moves, the slots opened on it gradually align with the heat dissipation holes 2 and eventually connect. At this time, if the fan 5 starts blowing air, the air can flow smoothly through these aligned holes, thereby achieving effective heat dissipation.

[0056] When fan 5 finishes its blowing action and moves away, the previously compressed spring 19 uses its own rebound force to push the sealing plate 16 back to its initial position. As the sealing plate 16 resets, the slots on it are misaligned with the heat dissipation hole 2 again, thus re-sealing the heat dissipation hole 2. Figure 9 As shown, the dotted line represents the blocked heat dissipation hole 2. This design not only ensures effective air circulation when heat dissipation is needed, but also allows for timely sealing of the heat dissipation hole 2 when heat dissipation is not needed, preventing the entry of dust and other impurities, and effectively protecting the safe and stable operation of the equipment inside the cabinet 1.

[0057] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
