Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to solve the problem that in the prior art, photovoltaic power generation and energy storage equipment uses energy storage cabinets to wrap and protect energy storage batteries, but the energy storage cabinets can only be unfolded to one side during energy storage to expose the internal energy storage batteries, and cannot cope with different overall installation orientations and usage requirements, this embodiment provides the following technical solutions:

[0023] An energy storage device for photovoltaic power generation equipment comprises a housing 1, an energy storage battery is arranged in the middle of the housing 1, and a photovoltaic panel is arranged obliquely on the upper end of the housing 1, such as Figure 1 and Figure 2 As shown, the photovoltaic panel and the energy storage battery are electrically connected, and the heat converted from the light energy absorbed by the photovoltaic panel is transmitted through the cable and stored inside the energy storage battery. Brackets 2 are arranged at the four corners of the lower end of the shell 1, and the upper ends of the four brackets 2 are welded and fixed to the lower end of the shell 1. The installation and support of the brackets 2 can prevent the shell 1 and the internal energy storage battery from contacting the ground, and prevent the shell 1 from rusting due to contact with the liquid on the ground, and prevent the liquid on the ground from contacting the energy storage battery to cause a short circuit;

[0024] In this embodiment, four operating grooves 13 are evenly distributed around the interior of the housing 1. The four operating grooves 13 all penetrate the housing 1 and extend to the interior of the housing 1. Figure 4 As shown, a protective panel 3 is provided at one end of the outside of the four operating grooves 13, and the operating grooves 13 and the energy storage motor placed inside can be wrapped and protected by the protective panel 3;

[0025] In this embodiment, the second sliding rails 8 are arranged on both sides of the operating groove 13, and the third sliding block 12 is arranged at one end outside the two second sliding rails 8. Figure 4 , Figure 5 and Figure 6 As shown, when sliding to expose the operating groove 13 and the internal energy storage battery, the third sliding block 12 is embedded in the second sliding rail 8 and slides vertically along the second sliding rail 8;

[0026] In this embodiment, the upper ends of the two third sliding blocks 12 are both provided with the first sliding rails 7, and the two sides of the first sliding rails 7 are both provided with the third sliding rails 9. Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the upper ends of the two second sliding rails 8 are each provided with a first sliding block 5, and the two sides of the first sliding block 5 are each provided with a second sliding block 10, and the second sliding block 10 and the first sliding block 5 are an integral structure, and when the protection panel 3 slides vertically and exposes the operation groove 13, the first sliding block 5 will slide in the first sliding rail 7, and the second sliding block 10 will slide in the third sliding rail 9, and the protection panel 3 can be prevented from falling off when sliding by the restriction of the third sliding rail 9;

[0027] In this embodiment, a return spring 6 is provided between the first sliding block 5 and the lower end of the first sliding rail 7. Figure 2 and Figure 3 As shown, the protective panel 3 can be actively reset after being slid out through the resilience of the reset spring 6;

[0028] In this embodiment, if Figure 1 , Figure 2 and Figure 4 As shown, four protective panels 3 are arranged in a ring shape, and a filling block 11 is arranged between two adjacent protective panels 3. The filling block 11 can fill the gap between two adjacent protective panels 3 to prevent foreign matter and medium from affecting the sliding and use of the protective panels 3;

[0029] In this embodiment, a heat sink 4 is disposed in the middle of the four protection panels 3. Figure 1 and Figure 2 As shown, the heat sink 4 is welded and fixed to the protection panel 3 , and the heat dissipation area can be increased by the depression and exposure of the heat sink 4 , which is convenient for heat dissipation of the protection panel 3 and helps to discharge the heat inside the housing 1 .

[0030] Working principle: when using the device and repairing and installing the internal storage battery, according to the installation direction, the protection panel 3 slides in the second sliding rail 8 through the third sliding block 12. While sliding, the outer shell 1 slides in the first sliding rail 7 through the first sliding block 5. During the sliding of the first sliding block 5, the second sliding blocks 10 on both sides slide in the third sliding rail 9. The sliding can expose the operating groove 13. The exposed operating groove 13 can directly operate the internal storage battery. When the pulling of the protection panel 3 stops, the resilience of the reset spring 6 inside the first sliding rail 7 can push the protection panel 3, so that the protection panel 3 is actively reset, and actively resets and wraps the operating groove 13 and the internal energy storage battery.
