In a solar photovoltaic power generation system, a photovoltaic energy storage cabinet can store solar energy, collect electric energy through a photovoltaic cell array, and connect to the grid, which is a key component of solar photovoltaic power generation.

[0003] Currently, in the existing solar photovoltaic energy storage cabinets in the prior art, most of them directly install the assembled battery pack modules in the cabinet body and then connect them through wires inside the cabinet body; however, for a photovoltaic energy storage cabinet used in a harsh outdoor environment, such as opening heat dissipation holes on the cabinet body, it is extremely easy to block the openings due to electrostatic adsorption and requires long-term cleaning. Moreover, since the photovoltaic energy storage cabinet is fixedly installed outdoors, it is inconvenient to clean; and due to the fact that the outdoor environment around the photovoltaic energy storage cabinet may be humid due to different seasons, long-term use will cause the battery to heat severely, which will greatly reduce the service life of the solar photovoltaic energy storage cabinet.

[0004] Therefore, it is urgent to design a protection device for a photovoltaic energy storage cabinet, which is used to be arranged outside the photovoltaic energy storage cabinet to help the electrical equipment inside the photovoltaic energy storage cabinet dissipate heat.

[0026] The height of the limiting block 35 is greater than the height of the sliding groove, and the width of the limiting block 35 is the same as the width of the sliding groove;

[0027] The elastic member is a spring 4.

[0028] One end of the extension plate 32 away from the sliding groove is fixedly installed with a rotating shaft, and a square block 33 is rotatably arranged on the rotating shaft; a blocking column 36 is formed on the extension plate 32; the height of the blocking column 36 is the same as the distance between the square block 33 and the extension plate 32.

[0029] On both the top and bottom of the thickened stopper 2, a fixing groove is provided on each side; the top of the fixing groove is a cubic structure, and the bottom of the fixing groove is an arc-shaped cubic structure bent towards the support plate 3; the width of the fixing groove is the same as that of the square block 33; the blocking column 36 corresponds to the bottom position of the fixing groove.

[0030] A row or two rows of tapered columns 5 are also fixedly installed on the bottom surface of the protective plate 1.

[0031] A cavity is formed on one side of the protective plate 1 facing the photovoltaic energy storage cabinet, and a number of inner support columns 12 are arranged in the cavity. One end of the inner support column 12 abuts against the outer wall of the photovoltaic energy storage cabinet.

[0032] Filter screens 13 are installed in the heat dissipation holes of the heat dissipation hole group 11, and a number of protection plates 14 are also fixedly installed in the cavity; the protection plates 14 are correspondingly arranged at the bottom end on the side of the heat dissipation holes facing the photovoltaic energy storage cabinet; and the protection plates 14 are arc-shaped plates, and the end surfaces thereof are adapted to the outer wall shapes of the heat dissipation holes.

[0033] The height of the protection plate 14 is half of the height diameter of the heat dissipation hole, and the protection plate 14 is an arc-shaped plate, and an arc surface is formed on its side wall.

[0034] In an embodiment of the present invention, extension edges are formed at the top and bottom of the protective plate 1, and the extension edges are hung on the top and bottom of the outer wall of the photovoltaic energy storage cabinet; the extension edges can realize the threaded installation of the protective plate 1 on the outer wall of the photovoltaic energy storage cabinet; and the connection and fixation with the photovoltaic energy storage cabinet are realized by cooperating with the inner support columns 12 arranged in the cavity.

[0035] Further, pads can be added at the ends of the inner support columns 12 to directly abut against the inner wall of the photovoltaic energy storage cabinet.

[0036] Further, suction cups can be arranged at the ends of the inner support columns 12 to make the protective plate 1 adsorbed on the outer wall of the photovoltaic energy storage cabinet.

[0039] In an embodiment of the present invention, transition surfaces are provided at both ends of the side of the square block 33 extending into the fixing groove, facilitating the cooperation between the square block 33 and the fixing groove. During assembly, first insert the square block 33 into the top of the fixing groove and extend it downward to the bottom of the fixing groove. Since the bottom of the fixing groove is inclined, the square block 33 rotates. At this time, the blocking column 36 provides support and limit for the square block 33, preventing the square block 33 from being retracted by the movement of the extension plate 32. If disassembly is required, only the support plate 3 can be moved upward, and then by pulling the limit block 35, the connecting rod 34 is stretched by the limit block 35, causing the sliding block 31 to slide in the sliding groove, and at the same time the extension plate 32 moves along the sliding groove, so that the square block 33 is disengaged from the top of the fixing groove.

[0040] In an embodiment of the present invention, due to the limitation of the spring 4, the support plate 3 and the thickened stopper 2 are firmly connected.

[0041] In an embodiment of the present invention, a fixing component is also detachably provided. The fixing component is arranged at the turning point of the support plate 3 to form a lateral support, including a support rod 71 and a rotating seat. When the fixing component needs to be used, first assemble the support rod 71 and the rotating seat 7. After assembly, then rotate the support rod 71 to a suitable position. After the support rod 71 is rotated, rotate the rotating block 72 to drive the hollow cone block 74 at the bottom of the disc 73 to rotate, so that the hollow cone block 74 and the ground are at a suitable angle. After the hollow cone block 74 rotates, push the hollow cone block 74 to insert the hollow cone block 74 into the soil. The auxiliary strip 74 plays a role in auxiliary support and rotational fixation in the soil, solving the problem that the protective plate 1 will be blown by strong wind and sand.
