[0034] like Figures 1 to 3 As shown, a mobile photovoltaic energy storage cabinet includes a base frame 1, two groups of long side frames 2, two groups of short side frames 3, energy storage batteries 4, a multi-layer mounting frame 5 and two groups of support parts, wherein:

[0035] The two groups of long side frames 2 are rotatably connected to the two long sides of the base frame 1, and the two groups of short side frames 3 are fixedly arranged at the two short sides of the base frame 1, respectively. The long side frames 2 are detachably connected to the adjacent short side frames 3;

[0036] A connecting frame 6 is provided on one side of the base frame 1, and the energy storage battery 4 is mounted on the connecting frame 6;

[0037] The two short side frames 3 are both provided with multi-layer multi-section slide rails 7, the multi-layer mounting frames 5 correspond to the multi-layer multi-section slide rails 7 one by one, and the mounting frames 5 are rotatably connected to the slide rails of the corresponding layers;

[0038] Both ends of the multi-layer mounting frame 5 are mounted on the two sets of short side frames 3 through multi-section slide rails 7, and the slide rails are provided with blocking rods for supporting the mounting frame 5. A plurality of solar panels are mounted on the mounting frame 5, and the plurality of solar panels are electrically connected to the energy storage battery 4;

[0039] The two groups of support parts are rotatably arranged on the two groups of long side frames 2 respectively;

[0040] The two groups of long side frames 2 can be in a horizontal state by rotating, the single-layer mounting frame 5 can be moved to the top of a long side frame 2 in a horizontal state, wherein the lowest layer of mounting frame 5 is a single layer, and the double-layer mounting frame 5 can be moved to the top of another long side frame 2 in a horizontal state. When the support part is rotated from a horizontal state to a vertical state, one end of the mounting frame 5 is supported by the support part, so that the mounting frame 5 is in an inclined state.

[0041] During the transfer process of the photovoltaic energy storage cabinet, the two groups of long side frames 2 are connected with the two groups of short side frames 3 to form a structure similar to a container, which is convenient for the transportation and transfer of the photovoltaic energy storage cabinet. When power generation is required, the two groups of long side frames 2 are rotated to make the long side frames 2 in a horizontal state, and the single-layer mounting frame 5 is controlled to move above a long side frame 2 in a horizontal state, and the double-layer mounting frame 5 is controlled to move above another long side frame 2 in a horizontal state. At this time, the single-layer mounting frame 5 and the double-layer mounting frame 5 both form a stepped distribution, and then the support part is controlled to rotate so that the support part is perpendicular to the horizontal long side frame 2. One end of the mounting frame 5 is supported by the support part, so that the mounting frame 5 is in an inclined state, and then the solar panel on the mounting frame 5 is in an inclined state, which is convenient for receiving solar radiation.

[0042] From the above, it can be seen that the photovoltaic energy storage cabinet includes multiple mounting frames 5, and multiple solar panels can be installed side by side on each mounting frame 5. Therefore, while ensuring a compact structure, the number of solar panels is greatly increased, thereby improving the power generation efficiency. When generating electricity, the solar panels can all be tilted towards the sun, further ensuring the power generation efficiency.

[0043] like Figure 2 and Figure 4 As shown, in some embodiments, the support portion includes a rotating shaft 8 rotatably connected to the long side frame 2, the rotating shaft 8 is provided with a through hole, the long side frame 2 is provided with a threaded positioning hole, and the rotating shaft 8 is positioned by passing a bolt 9 through the through hole and threadedly connected to the positioning hole. A plurality of groups of rods 10 are provided on the rotating shaft 8, and a support wheel 11 is rotatably connected to the top of the rod 10. A clamping member 12 is fixedly provided on the long side frame 2, and the clamping member 12 can be clamped with the rod 10. When the rod 10 and the long side frame 2 are in a parallel state, the rod 10 can be limited. The rod 10 corresponds one-to-one with the mounting frame 5. When the rod 10 is rotated to be perpendicular to the horizontal long side frame 2, the mounting frame 5 is supported by the support wheel 11, so that the mounting frame 5 and the solar panel are in an inclined state.

[0044] When working, the rod 10 starts as Figure 4 As shown in the fallen state, the lever 10 is clamped on the clamping member 12, the control lever 10 is separated from the clamping member 12, and then rotates with the shaft 8. When the lever 10 rotates to the position shown in FIG. Figure 3 When the long side frame 2 is perpendicular to the horizontal state, the rotation axis 8 is positioned by passing the bolt 9 through the through hole and threadedly connected with the positioning hole. At this time, the mounting frame 5 is supported by the support wheel 11, so that the mounting frame 5 and the solar panel are in an inclined state.

[0045] In some embodiments, the photovoltaic energy storage cabinet further includes a driving unit, which is disposed on the connecting frame 6 and is used to drive the movement of the mounting frame 5. In this way, no manual labor is required to move the mounting frame 5, thereby reducing the labor intensity of personnel.

[0046] like Figure 2 , Figure 5 and Figure 7 As shown, optionally, the driving unit includes a motor 13 and an intermediate plate 14 arranged on the connecting frame 6, the motor 13 is transmission-connected with a driving gear 15, the driving gear 15 is meshed with a driven gear 16, the driven gear 16 is fixedly sleeved with a first mounting rod 17, the first mounting rod 17 is rotatably connected to the connecting frame 6, a plurality of winding rollers 18 are fixedly arranged on the first mounting rod 17, and a plurality of winding rollers 18 are each provided with a pull rope 19, the intermediate plate 14 is detachably connected to the long side frame 2, the second mounting rod 20 and the third mounting rod 21 are detachably connected to the intermediate plate 14, and the second mounting rod 20 and the third mounting rod 21 are detachably connected to the long side frame 2. A plurality of reversing wheels 22 are rotatably connected to 21, a hook is provided at one end of the pull rope 19, and through grooves cooperating with the hook are provided at both ends of the mounting frame 5. A support rod 23 is rotatably provided on the intermediate plate 14, and a first bevel gear 24 is fixedly provided on the top of the support rod 23, and the first bevel gear 24 is meshed with a second bevel gear 25, and a connecting rod 26 is provided at one end of the second bevel gear 25, and the connecting rod 26 is detachably connected to the rotating shaft 8, and a rack 27 is slidably connected to the intermediate plate 14, and an annular convex tooth is provided on the support rod 23, and the rack 27 is meshed with the convex tooth, and the rack 27 is also provided with a through groove cooperating with the hook.

[0047] During operation, when the driving part is not needed, some parts of the driving part can be disassembled for easy transportation and transfer. When the driving part is needed, the intermediate plate 14 and other parts can be installed first through the above-mentioned connection method. After the pull rope 19 passes through the reversing wheels 22 on the second mounting rod 20 and the third mounting rod 21, it is matched with the through groove through the hook. Only one hook is matched with the through groove at a time. The motor 13 is powered by the photovoltaic energy storage cabinet, and the driving gear 15 is driven to rotate through the operation of the motor 13. The driving gear 15 drives the driven gear 16 to rotate, and the driven gear 16 drives the first mounting rod 17 to rotate, thereby driving the winding roller 18 to reel, thereby driving the mounting frame 5 to move through the pull rope 19. At the same time, at an appropriate time, for example, when the other mounting frames 5 are moved into place and only the last one to pull the top mounting frame 5 is left, the lowest hook can be hung on the through groove on the rack 27, so that when the mounting frame 5 is pulled, the rack 27 will also be pulled, and the movement of the rack 27 will drive the support rod 23 to rotate, thereby driving the first bevel gear 24 to rotate, the first bevel gear 24 drives the second bevel gear 25 to rotate, and the second bevel gear 25 drives the rotating shaft 8 to rotate, thereby driving the rod 10 to rotate, realizing the supporting function of the rod 10, so that in the process of pulling the mounting frame 5, the rotation of the support part is realized at the same time, so that the support part plays a supporting role for each moving mounting frame 5.

[0048] In some embodiments, the photovoltaic energy storage cabinet also includes a cleaning part, which is arranged on the rod 10. The rod 10 is a telescopic rod. By controlling the overall length of the rod 10, the inclination angle of the solar panel during support can be controlled. The cleaning part is used to clean the solar panel. After the solar panel has been used for a period of time, there will be dust on it. A large amount of dust will affect the power generation efficiency. Therefore, the present invention designs a cleaning part for cleaning.

[0049] like Figure 2 and Figure 6 As shown, optionally, the cleaning portion includes a top plate 28 detachably connected to the rod 10 and a cleaning cloth 29 installed on the top plate 28, the top plate 28 is detachably connected to the rod 10 by snapping, a through hole is provided on the long side frame 2 for passing the pull rope 19, the rod 10 is detachably connected to the rotating shaft 8, each of the rod 10 has two installation positions on the rotating shaft 8, when the rod 10 is located at the first installation position, the long side frame 2 is in a horizontal state, and the mounting frame 5 is supported by the support wheel 11, when the rod 10 is located at the second installation position, the long side frame 2 is in a vertical state, during the movement of the mounting frame 5 above the other long side frame 2 in a horizontal state, the cleaning portion can clean the solar panel during the movement.

[0050] During cleaning, for example, when the photovoltaic energy storage cabinet is in the power generation on state, the double-layer solar panel needs to be cleaned, the pull rope 19 on the double-layer solar panel side is connected to the single-layer mounting frame 5, and then the single-layer solar panel is recovered and returned to its original position through the operation of the motor 13 on the double-layer solar panel side. After returning to its original position, the rod 10 under the original single-layer solar panel is laid down, and the rod 10 is adjusted from the first installation position to the second installation position, and then the long side frame 2 on this side is rotated to rotate the long side frame 2 from the horizontal state to the vertical state, and then the rod 10 is rotated again to make the rod 10 vertical. With the long side frame 2, the cleaning part is then clamped on the rod 10. At this time, the pull rope 19 on the side of the single-layer solar panel is passed through the vertical long side frame 2 through the through hole and connected to the double-layer mounting frame 5. Through the operation of the single-layer solar panel side motor 13, the double-layer solar panel is pulled. When the solar panel passes through the cleaning cloth 29, it is cleaned by the cleaning cloth 29. The length of the cleaning cloth 29 is the same as the length of the mounting frame 5. Therefore, all solar panels on the mounting frame 5 can be cleaned. The principle of cleaning the single-layer solar panel is similar to that of the double-layer solar panel, which will not be repeated here. Compared with manual cleaning, the above method can clean all solar panels more automatically and quickly, and at the same time reduce the labor intensity of manual work.

[0051] In some embodiments, corner pieces are fixedly provided at the top corners of the upper ends of the two groups of short side frames 3, and the corner pieces are used to cooperate with the crane to transfer the photovoltaic energy storage cabinet. The crane can lift the photovoltaic energy storage cabinet through the corner pieces and then transfer it to the transport vehicle, which facilitates the transportation and transfer of the photovoltaic energy storage cabinet.

[0052] In some embodiments, one end of the connecting rod 26 is provided with a thread, and one end of the rotating shaft 8 is provided with a threaded hole, and the connecting rod 26 and the rotating shaft 8 are detachably connected by threaded connection.

[0053] It should be understood by those skilled in the art that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the above aspects of the present invention, which are not provided in detail for the sake of simplicity.
