[0002] In a solar photovoltaic power generation system, the photovoltaic energy storage cabinet is a very key component, which plays an important role in power storage and access to the grid. It can efficiently collect and store the power collected by the solar photovoltaic cell array when the light is sufficient, and release the stored power when the power demand is high or the light is insufficient, ensuring the stability of power supply, and effectively promoting the widespread application of solar energy, a renewable energy source.

[0003] The fan, as the main heat dissipation element, is usually fixedly installed on the cabinet body. The fan rotates to blow air into the internal space of the cabinet body, so that the heat in the cabinet body is discharged from the air outlet on the other side to achieve heat exchange. However, the blowing area of the fan cannot cover all areas of the cabinet body, which will lead to uneven heat dissipation effect in different areas of the cabinet body, and further cause the photovoltaic energy storage cabinet to have performance degradation, shortened service life, and safety hazards, etc. SUMMARY

[0004] In order to improve the heat dissipation effect of the energy storage cabinet, the present application provides a photovoltaic energy storage cabinet structure.

[0015] By adopting the technical scheme, the driving motor operates to drive the heat dissipation fan to reciprocating rotate, meanwhile, under the cooperation of the outer gear cam part and the roller, the first wedge block also reciprocating moves in the first sliding groove, the first wedge block cooperates with the second wedge surface to make the second wedge block move, the second wedge block cooperates with the third wedge surface and the fourth wedge surface to drive the third wedge block to reciprocating move in the third sliding groove along the vertical direction, the third wedge block drives the driving rack to move, so that the adjustment of the louver outflow gap can be realized.

[0017] By adopting the technical scheme, one cam part corresponds to the adjacent first tooth part and the second tooth part, the rolling gear cooperates with the adjacent first tooth part and the second tooth part to complete the rotation, at this time, the first wedge block also completes one lifting action, so that the angle adjustment of the outflow gap is adapted to the rotation of the heat dissipation fan.

[0018] Preferably, when the rolling gear meshes with the second tooth part to rotate, the heat dissipation fan rotates downward, when the rolling gear meshes with the first tooth part to rotate, the heat dissipation fan rotates upward.

[0019] By adopting the technical scheme, the linear length of the first tooth part and the second tooth part is same, that is, the rolling angle of the rolling gear is same when the rolling gear meshes with the first tooth part and the second tooth part, but because the radius of the inner gear is smaller than the radius of the outer gear, under the condition that the linear distance of the rotation of the inner gear and the outer gear is same, the rotation angle of the outer gear is smaller, that is, under the condition that the rolling gear rotates the same angle, the rotation angle of the outer gear is smaller than the rotation angle of the inner gear, that is, when the rolling gear meshes with the second tooth part of the inner gear to rotate, the rolling gear will complete the rotation slowly; that is, in practice, the heat dissipation fan is not swing at uniform speed, the speed of the heat dissipation fan is slow when rotating downward, and the speed is fast when rotating upward; because the hot air generated in the cabinet flows upward, the temperature of the upper part of the cabinet is relatively higher than the lower part, when the fan gradually rotates downward, by reducing the speed, the heat dissipation effect on the upper side can be increased, and the heat dissipation effect is further improved; during the process of the fan rotating downward, the upper part can be gradually transported downward and finally discharged; during the process of the fan rotating upward, the hot air of the upper part is pressed into the cabinet, which has adverse effect on heat dissipation, therefore, by reducing the speed of the fan rotating downward, the heat dissipation effect of the energy storage cabinet can be improved.

[0021] 1. By the outer gear and the inner gear drive rolling gear reciprocating rotation, realize the reciprocating rotation of the heat dissipation fan, increase the heat dissipation area, help to improve the heat dissipation effect of the energy storage cabinet;

[0022] 2. By adjusting the angle of the blade, the angle of the air outlet gap is changed to follow the rotation angle of the heat dissipation fan, which can better guide the hot air to quickly exhaust from the cabinet body and ensure the heat dissipation effect;

[0023] 3. When the rolling gear cooperates with the outer gear and the inner gear, the rolling gear cooperates with the second tooth part of the inner gear, the rotation speed of the rolling gear is slow, that is, the downward rotation speed of the heat dissipation fan is relatively slow, which helps to increase the heat dissipation time of the upper space. The hot air is mainly concentrated on the upper side, and through this way, the heat dissipation effect of the cabinet body can be improved. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0032] The following description will be made in conjunction with the accompanying drawings. Figures 1-7 The application is further described in detail.

[0033] The application discloses a photovoltaic energy storage cabinet structure.

[0034] Referring to Figure 1 , Figure 2 and Figure 3 , the photovoltaic energy storage cabinet structure comprises a cabinet 1, which is used for mounting battery packs and other elements. A communication port 2 is formed in one side wall of the cabinet 1. A connecting shaft 3 is rotatably arranged in the cabinet 1 at the communication port 2. A mounting plate 4 is fixedly installed on the connecting shaft 3. A cooling fan 41 is installed on the mounting plate 4. A drive assembly 5 is arranged on the cabinet 1 and drives the mounting plate 4 to reciprocating swing. A louver assembly is further installed on the opposite side wall of the cabinet 1 at the communication port 2. When the cooling fan 41 blows air into the cabinet 1, the hot air is discharged from the louver assembly.

[0035] After the cooling fan 41 is started, the energy storage cabinet can be cooled. The mounting plate 4 is driven to reciprocating rotate by the drive assembly 5, so that the blowing area of the cooling fan 41 can be dynamically changed. The reciprocating rotation expands the effective coverage range of the fan, avoids the blind area caused by single fixed angle blowing, and improves the uniformity of air flow in the cabinet 1, which helps to improve the cooling effect of the energy storage cabinet.

[0036] The cabinet body 1 is fixedly installed with a mounting shell 11 on the circumferential side of the communication port 2, the mounting shell 11 is connected with the cabinet body 1 through bolts, the heat dissipation fan 41 is located in the mounting shell 11, and the mounting shell 11 is provided with an air inlet 111; the driving assembly 5 comprises a driving motor 51, an outer gear 52 and an inner gear 53, the driving motor 51 is fixedly installed on the cabinet body 1, the output shaft of the driving motor 51 extends into the communication port 2, the outer gear 52 and the inner gear 53 are coaxially fixed on the output shaft of the driving motor 51, the outer gear 52 and the inner gear 53 are concentric circles, a plurality of first tooth parts 521 are formed at the inner side of the outer gear 52 in intervals, a plurality of second tooth parts 531 are formed at the outer circumferential side of the inner gear 53 in intervals, the first tooth parts 521 and the second tooth parts 531 are staggered, the end of the connecting shaft 3 is coaxially fixed with a rolling gear 31, and the rolling gear 31 is located between the outer gear 52 and the inner gear 53. The rolling gear 31 is sequentially meshed with the first tooth parts 521 and the second tooth parts 531.

[0037] Through the sequential meshing of the first tooth parts 521 and the second tooth parts 531 with the rolling gear 31, the heat dissipation fan 41 realizes reciprocating swing under the continuous rotation of the motor, significantly expands the heat dissipation coverage area, and improves the uniformity of air flow in the energy storage cabinet through the bidirectional disturbance of airflow, effectively avoids the accumulation of local hot spots, and greatly enhances the heat dissipation efficiency and uniformity.

[0038] When the driving motor 51 operates, the outer gear 52 and the inner gear 53 are synchronously driven to rotate. When the first tooth part 521 of the outer gear 52 is meshed with the rolling gear 31, the rolling gear 31 is driven to rotate, and the rolling gear 31 drives the mounting plate 4 and the heat dissipation fan 41 to rotate upward through the connecting shaft 3; after the rolling gear 31 is disengaged from the meshing with the outer gear 52, it is immediately meshed with the second tooth part 531 of the inner gear 53, and the rolling gear 31 is driven to rotate in the opposite direction, driving the heat dissipation fan 41 to rotate downward.

[0039] The linear length of the first tooth part 521 and the second tooth part 531 is equal, so the rolling angle of the rolling gear 31 when meshed with the two is the same. However, due to the smaller radius of the inner gear 53 than the outer gear 52, the rotation angle of the outer gear 52 is smaller under the same linear distance rotation. This characteristic leads to:

[0040] The outer gear 52 driving stage (fan rotating upward): the radius of the outer gear 52 is large, the angle changes little when rotating the same linear distance, the rolling gear 31 needs to quickly complete the same angle rotation, and the fan swings upward at a faster speed;

[0041] The inner gear 53 driving stage (fan rotating downward): the radius of the inner gear 53 is small, the angle changes greatly when rotating the same linear distance, the rolling gear 31 can slowly complete the same angle rotation, and the fan swings downward at a slower speed.

[0042] Due to the natural upward flow of hot air, the upper part of the cabinet 1 has a higher temperature. When the fan rotates downward, the speed is slow, which prolongs the airflow coverage time of the high-temperature area in the upper part, enhances the heat exchange efficiency through continuous blowing, and effectively reduces the heat accumulation in the upper part.

[0043] When rotating downward, the slow airflow pushes the hot air in the upper part to gradually diffuse to the lower layer, forming a "top-down" heat dissipation path, and finally being discharged through the air outlet gap 62.

[0044] When rotating upward, although the hot air may be temporarily squeezed to flow back to the middle part of the cabinet 1, the fast swing moment can reduce the residence time and avoid excessive heat accumulation.

[0045] The speed control achieved by the difference in gear radius dynamically matches the swing rhythm of the heat dissipation fan 41 with the heat field distribution of the cabinet 1, forming a heat dissipation mode of "slow scanning of high-temperature area and fast cutting of backflow area", which significantly improves the heat dissipation uniformity and overall efficiency of the energy storage cabinet.

[0046] Referring to Figure 2 , Figure 4 and Figure 5 , the side wall of the cabinet 1 is provided with an air outlet 12, the louver assembly includes a plurality of blades 6, all the blades 6 are rotationally connected at the air outlet 12 through a shaft 61, and an air outlet gap 62 is formed between adjacent blades 6. The cabinet 1 is provided with a rotating assembly 7 for driving all the blades 6 to rotate synchronously.

[0047] The cabinet 1 is provided with a receiving groove 121 on one side of the air outlet 12, and the shaft 61 extends into the receiving groove 121. The rotating assembly 7 includes a driven gear 71, a transmission gear 72 and a driving rack 73. The end portions of the rotating assembly 7 are coaxially fixed with the driven gear 71. The transmission gear 72 is rotationally connected between adjacent driven gears 71 and meshes with adjacent driven gears 71. The driving rack 73 is vertically arranged on the cabinet 1 and meshes with the uppermost driven gear 71. The cabinet 1 is provided with a linkage assembly 8 for driving the driving rack 73 to move reciprocally.

[0048] When the linkage assembly 8 drives the driving rack 73 to reciprocate and slide, one of the driven gears 71 is driven to rotate, and through the power transmission of the transmission gear 72, all the driven gears 71 are synchronously and uniformly rotated, thereby driving the blades 6 to rotate and realizing the adjustment of the air outlet gap 62. Changing the orientation of the air outlet gap 62 can adapt the blowing direction of the cooling fan 41. When the cooling fan 41 blows upward, the blades 6 are rotated to be inclined and inclined downward from the cabinet 1. Since the hot air in the cabinet 1 flows from top to bottom to the air outlet 12 at this time, changing the angle of the air outlet gap 62 to adapt the flow direction of the hot air can better guide the hot air in the cabinet 1 to be quickly discharged from the cabinet 1. Similarly, when the cooling fan 41 blows downward, the blades 6 are synchronously rotated to switch to another inclination angle. Through the rotation of the blades 6, the hot air in the cabinet 1 can be quickly discharged, and the cooling effect is improved.

[0049] With reference to Figure 5 , Figure 6 and Figure 7 , the linkage assembly 8 comprises a first wedge block 81, a second wedge block 82 and a third wedge block 83, the outer periphery of the outer gear 52 is integrally formed with a plurality of continuously and spacedly distributed cam portions 522, any cam portion 522 corresponds to adjacent first tooth portion 521 and second tooth portion 531, the sidewall of the cabinet 1 is provided with a first sliding groove 13 in the vertical direction, the first wedge block 81 slides in the first sliding groove 13 in the vertical direction, the lower end of the first wedge block 81 is provided with a roller 9, the roller 9 always abuts against the outer periphery of the outer gear 52, the upper side of the first wedge block 81 is further formed with a first wedge surface 811, the top end of the first sliding groove 13 is provided with a first compression spring 131, one end of the first compression spring 131 is connected with the top wall of the first sliding groove 13, and the other end is connected with the upper end of the first wedge block 81.

[0050] The top wall of the cabinet 1 is provided with a second sliding groove 14, the second sliding groove 14 is horizontally arranged, and the second sliding groove 14 is communicated with the first sliding groove 13, the second wedge block 82 slides in the second sliding groove 14, the second wedge block 82 is provided with a first through groove 821, the first wedge block 81 is inserted and slidably connected with the first through groove 821, the inner wall of the first through groove 821 is formed with a second wedge surface 822 matched with the first wedge surface 811, and the second sliding groove 14 is provided with a second compression spring 141, one end of the second compression spring 141 is connected with the inner wall of the second sliding groove 14, and the other end is connected with the end of the second wedge block 82.

[0051] The third sliding groove 15 is arranged on the vertical wall of the cabinet body 1, and the lower end of the third sliding groove 15 is connected with the accommodating groove 121. The end of the second wedge-shaped block 82 is provided with a third wedge surface 823. The third wedge-shaped block 83 is provided with a second penetrating groove 831. The second wedge-shaped block 82 is inserted and matched with the second penetrating groove 831. The inner wall of the second penetrating groove 831 is provided with a fourth wedge surface 832 matched with the third wedge surface 823. The top of the third sliding groove 15 is provided with a third compression spring 151. One end of the third compression spring 151 is connected with the inner wall of the third sliding groove 15, and the other end is connected with the upper end of the third wedge-shaped block 83. The lower end of the third wedge-shaped block 83 is fixedly connected with the driving rack 73.

[0052] When the driving motor 51 operates, the cam portion 522 of the outer gear 52 is matched with the roller 9, so that the circular motion is converted into the reciprocating linear motion of the first wedge-shaped block 81 in the first sliding groove 13. The up-down movement of the first wedge-shaped block 81 is converted into the movement of the second wedge-shaped block 82 in the horizontal direction through the sliding matching of the first wedge surface 811 and the second wedge surface 822. The second wedge-shaped block 82 drives the third wedge-shaped block 83 to make reciprocating motion in the vertical direction through the matching of the third wedge surface 823 and the fourth wedge surface 832, and finally drives the driving rack 73 to realize the linear reciprocating movement.

[0053] The implementation principle of the photovoltaic energy storage cabinet structure in the embodiment of the application is as follows: the driving motor 51 reciprocatingly rotates the heat dissipation fan 41, increases the heat dissipation area, and helps to improve the heat dissipation effect of the energy storage cabinet. When the heat dissipation fan 41 rotates, the cam portion 522 on the outer gear 52 is matched with the first wedge-shaped block 81, so that the power is transmitted to the driving rack 73, that is, all the blades 6 are synchronously driven to rotate, the angle of the air outlet gap 62 is changed, the angle of the air outlet gap 62 is the same as the flow direction of the hot air, and then the hot air is quickly discharged. In addition, because the diameters of the outer gear 52 and the inner gear 53 are different, the rotating speeds of the rolling gear 31 when meshing with the two gears are different. That is, when the rolling gear 31 meshes with the inner gear 53 to rotate, the rolling gear 31 rotates slowly, that is, the speed of the heat dissipation fan 41 rotating downward is slow. Because the hot air in the cabinet body 1 flows upward spontaneously, the heat dissipation fan 41 slowly rotates downward, which helps to improve the heat dissipation effect on the upper side of the cabinet body 1, and then improves the heat dissipation effect of the energy storage cabinet.

[0054] The above are the preferred embodiments of the application, which do not limit the protection scope of the application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the application should be covered by the protection scope of the application.
