DETAILED DESCRIPTION

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] like Figure 1-Figure 5 As shown, a photovoltaic energy storage device that is easy to maintain includes an energy storage cabinet 1, a motor 3, and an energy storage battery 6. A protective box 2 is fixed on one side of the energy storage cabinet 1, and a motor 3 is provided at the bottom end of the protective box 2. The motor 3 is fixed to one side of a fixing seat 301, and the fixing seat 301 is fixed to the bottom end of the protective box 2. The motor 3 is connected to and drives a worm 4. A bracket 103 is fixed in the inner cavity of the energy storage cabinet 1, and an energy storage battery 6 slides in a slideway of the bracket 103. A moving block 601 is provided on one side of the energy storage battery 6. The moving block 601 and the worm 4 are connected to a moving assembly 5. The moving assembly 5 includes a worm wheel 501 meshed with the worm 4. A screw 502 is connected to the center of the worm wheel 501. The screw 502 passes through the moving block 601 and is in a threaded connection relationship with the moving block 601. Both ends of the screw 502 are connected to the mounting blocks 503, and the mounting blocks 503 at both ends are respectively fixed to the inner walls of the energy storage cabinet 1 and the protective box 2.

[0024] As mentioned above, in this case, when maintenance is needed, the motor 3 is started, and the motor 3 drives the worm 4 connected to the protective box 2 to rotate. The rotation of the worm 4 drives the worm wheel 501 to rotate, and drives the screw 502 connected to the center of the worm wheel 501 to rotate. The moving block 601 threadedly connected to the screw 502 moves outward accordingly, driving the energy storage battery 6 to slide outward in the slideway of the bracket 103. The bracket 103 is provided with a multi-layer slideway, and multiple energy storage batteries 6 can be placed at the same time and moved. The energy storage battery 6 slides until the moving block 601 contacts the mounting block 503 on the inner wall of the energy storage cabinet 1 and stops moving. At this time, the energy storage battery 6 is moved outside the energy storage cabinet 1, and the equipment can be conveniently maintained. The device has high safety, is easy to use, and is quick and convenient for equipment maintenance.

[0025] The energy storage cabinet 1 is provided with four fixed legs 102 at the bottom, and the base 7 is placed at the bottom of the fixed legs 102 and fixed through screw holes. Four wheels 701 are installed at the bottom of the base 7, and brake pads are installed on the wheels 701. A cabinet door 101 is opened on one side of the energy storage cabinet 1, and a working observation port is provided in the middle of the cabinet door 101, and glass 1011 is installed on the inner wall of the working observation port.

[0026] As mentioned above, a fixed leg 102 is provided at the bottom of the energy storage cabinet 1, and the fixed leg 102 is placed on the top of the base 7 and fixed to the four corners of the base 7 with bolts. Wheels 701 with brake pads are installed at the bottom of the base 7 to isolate the energy storage cabinet 1 from the ground, reduce damage, and facilitate the movement and fixation of the device. A cabinet door 101 with a working observation port is provided on one side of the energy storage cabinet 1, and a glass 1011 is installed on the inner wall of the working observation port, which can facilitate the staff to observe the status of the energy storage battery 6 and maintain it in time, thereby improving safety.

[0027] A rubber pad 504 is pasted on one side of the mounting block 503 fixed to the inner wall of the energy storage cabinet 1, and a box door 201 is opened on one side of the protection box 2 and connected by a hinge.

[0028] As mentioned above, a rubber pad 504 is pasted on the mounting block 503 on the inner wall of the energy storage cabinet 1, which plays a buffering role when the energy storage battery 6 moves to the outermost moving block 601 and contacts the mounting block 503, thereby protecting the safety of the components and preventing damage to the components due to impact. A box door 201 is connected to one side of the protective box 2 through a hinge, which is convenient for opening the worm wheel 501 and worm 7 for maintenance, thereby preventing damage to the components due to long-term use.

[0029] A plurality of heat dissipation openings are arranged in a matrix on both sides of the energy storage cabinet 1, and dustproof nets 105 are installed on the heat dissipation openings. A waterproof cover 104 is arranged on the side wall of the energy storage cabinet 1 above the dustproof net 105, and a rainproof shed 106 is installed on the top of the energy storage cabinet 1. Both sides of the rainproof shed 106 are inclined structures, and the length of the inclined surface exceeds the energy storage cabinet 1. A layer of waterproof coating is arranged on the overall outer surface of the energy storage cabinet 1.

[0030] As mentioned above, the heat dissipation ports are provided on both sides of the energy storage cabinet 1, and a dustproof net 105 is fixed on the heat dissipation port. A waterproof cover 104 is fixed on the outside of the heat dissipation port. The heat dissipation ports are provided on both sides to enhance air circulation and then dissipate the heat inside the energy storage cabinet 1. The installed dustproof net 105 and waterproof cover 104 can reduce dust, impurities and rainwater from entering the interior of the energy storage cabinet 1 and causing damage to the energy storage components, thereby playing a good protective role. The rainproof canopy 106 on the top of the energy storage cabinet 1 and the waterproof coating on the outside of the energy storage cabinet 1 can effectively prevent rainwater from entering the interior of the energy storage cabinet 1, thereby protecting the safety of the energy storage equipment.

[0031] Working principle: When maintenance is needed in this case, after the energy storage cabinet 1 is moved to a suitable position, the brake pads of the wheels 701 are opened to fix them, the cabinet door 101 is opened, and the motor 3 is started. The motor 3 drives the worm 4 connected to the protective box 2 to rotate, and the rotation of the worm 4 drives the worm wheel 501 to rotate, and drives the screw 502 connected to the center of the worm wheel 501 to rotate, and the moving block 601 threadedly connected to the screw 502 moves outward, driving the energy storage battery 6 to slide outward in the slideway of the bracket 103. The bracket 103 is provided with multi-layer slideways, and multiple energy storage batteries 6 can be placed at the same time and moved. The energy storage battery 6 slides until the moving block 601 contacts the rubber pad 504 on the mounting block 503 on the inner wall of the energy storage cabinet 1 and stops moving. At this time, the energy storage battery 6 is moved outside the energy storage cabinet 1, and the equipment can be easily maintained.
