It is a new type of power generation and comprehensive energy utilization method with broad development prospects. It advocates the principles of generating electricity nearby, connecting to the grid nearby, converting nearby, and using nearby. It can not only effectively increase the power generation of a photovoltaic power station of the same scale, but also effectively solve the loss problem of electricity during step-up and long-distance transportation.

[0003] According to the Chinese patent with the announcement number: CN218301336U, a distributed photovoltaic power generation and energy storage device includes a base, a support column, a solar panel, and an energy storage battery. An energy storage battery is installed in the middle of the top of the base. Support frames and support columns are installed at both ends of the top of the base, and the tops of the support frames and support columns are both connected to the solar panel. A second motor is installed at one end of the solar panel, and a threaded shaft is connected to the output end of the second motor. A limiting plate is installed at one end of the threaded shaft.

[0004] In the above solution, the energy storage battery is installed on the base, which still has the following disadvantages: the space on the top surface of the base is limited, which may reduce the number of energy storage batteries that can be installed, and may cause the current generated by photovoltaic power generation to not be fully stored in the insufficient number of energy storage batteries, reducing the utilization rate of space. Content of the Utility Model

[0005] The purpose of the utility model is to provide a distributed photovoltaic power generation energy storage device to solve the problems that may reduce the number of energy storage batteries that can be installed, may cause the current generated by photovoltaic power generation to not be fully stored in the insufficient number of energy storage batteries, and reduce the utilization rate of space.

[0006] To achieve the above-mentioned utility model purpose, the utility model adopts the following technical scheme: a distributed photovoltaic power generation energy storage device includes a plurality of energy storage boxes. A plurality of storage slots are opened on one side of the energy storage box. A storage battery is detachably arranged inside the storage slot. A fixing port is opened on one side of the storage battery. A handle is rotatably arranged inside the fixing port. First threaded grooves are respectively opened at the four corners of the top surface of the energy storage box. Fixing rings are respectively fixed at the four corners of the bottom surface of the energy storage box. A bearing is fixed inside the fixing ring. A rotating column is fixedly inserted into the inner wall surface of the inner ring of the bearing. The rotating column of the upper energy storage box is threadedly connected to the first threaded groove of the lower energy storage box.

[0007] Preferably, a plurality of mounting grooves are formed in one side of the energy storage box, and indicator lights are fixed inside the mounting grooves.

[0008] Preferably, a closing door is rotatably arranged on one side of the energy storage box. One side of the energy storage box and one side of the closing door are rotatably arranged through a hinge. A turning plate is rotatably arranged on the other side of the closing door. A positioning post is fixed on one side of the energy storage box. A positioning hole is formed in one side of the turning plate. The positioning post is slidably inserted into the positioning hole. A limiting ring is fixedly sleeved on the surface of the positioning post.

[0009] Preferably, a fixing plate is detachably arranged on the top surface of the uppermost energy storage box. A photovoltaic panel is arranged above the fixing plate. A plurality of support plates are fixed between the fixing plate and the photovoltaic panel.

[0010] Preferably, a second threaded groove is formed in the top surface of the energy storage box. A threaded post is fixed on the bottom surface of the fixing plate. The second threaded groove is in threaded connection with the threaded post.

[0011] Preferably, a plurality of anti-slip pads are detachably arranged below the lowermost energy storage box. A third threaded groove is formed in the top surface of the anti-slip pad. The third threaded groove is in threaded connection with the bottom ends of the rotating columns at the four corners of the bottom surface of the lowermost energy storage box.

[0012] Compared with the prior art, a distributed photovoltaic power generation energy storage device adopting the above technical scheme has the following beneficial effects:

[0013] First, as the power in the storage battery increases, the number of lit indicator lights will increase, which is convenient for the staff to understand the current power in the storage battery. The staff will stack multiple energy storage boxes together, and during the stacking process, the rotating column below the upper energy storage box will be screwed into the first threaded groove on the top surface of the lower energy storage box. During this process, the staff will rotate the rotating column around the bearing, and then the rotating column can be screwed into the first threaded groove, so that two energy storage boxes can be stacked together, and the firmness of the position between the two energy storage boxes can be increased. By stacking the height of the energy storage boxes, the lateral occupied area of the energy storage boxes on the ground is reduced, and the utilization rate of space is increased;

[0014] Second, the fixing plate is installed on the top surface of the uppermost energy storage box, which not only increases the height of the photovoltaic panel but also can better receive sunlight, avoiding the light of the photovoltaic panel being blocked by shrubs in the nearby environment. During the daily operation of the energy storage box, the closing door fits on one side of the energy storage box, protecting the storage battery inside the energy storage box and increasing the safety of the storage battery during power generation and energy storage;

[0015] Thirdly, anti-slip pads are installed at the four corners of the bottom of the lowermost energy storage box, which can increase the friction between the energy storage box and the ground and also enhance the stability of the energy storage box on the ground. When the anti-slip pads or photovoltaic panels are damaged, the staff can disassemble and replace the fixing plate and the anti-slip pads, thus increasing the service life of the energy storage device.

A plurality of installation grooves 15 are provided on one side of the energy storage box 1. An indicator light 16 is fixed inside the installation groove 15.

[0023] In use, as the power in the storage battery 3 increases, the number of lit indicator lights 16 will increase, facilitating the staff to understand the current power in the storage battery 3. The staff will stack multiple energy storage boxes 1 together, and during the stacking process, the rotating column 9 under the upper energy storage box 1 will be screwed into the first threaded groove 6 on the top surface of the lower energy storage box 1. During this process, the staff will rotate the rotating column 9 with the bearing 8 as the center, and then the rotating column 9 can be screwed into the first threaded groove 6, thereby stacking two energy storage boxes 1 and increasing the firmness of the position between the two energy storage boxes 1. By stacking the height of the energy storage boxes 1, the lateral occupied area of the energy storage boxes 1 on the ground is reduced, increasing the utilization rate of space.
