Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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. Example

[0026] A prefabricated substation for photovoltaic power generation, including four embedded parts 1 buried underground, wherein the embedded parts 1 are plugged with preassembled parts 2, the inner sides of the four preassembled parts 2 are welded with connecting plates 3, the tops of the four preassembled parts 2 are provided with bases 4, the four corners of the top of the base 4 are plugged with fastening bolts 5, the bottom ends of the fastening bolts 5 pass through the preassembled parts 2 and penetrate into the embedded parts 1, the top of the base 4 is provided with two card slots 6, the insides of the card slots 6 are plugged with card blocks 9, the tops of the two card blocks 9 are fixedly connected with power station boxes 11, one side of the base 4 is penetrated with two fastening bolts 10, one end of the fastening bolt 10 passes through the card block 9 and penetrates to the outside of the base 4.

[0027] The specific usage process is as follows: when installing the substation, first dig a matching soil pit at a suitable position, and then directly bury the four embedded parts 1 into the corresponding pits. It should be noted that in order to ensure the stability of the embedded parts 1, a base plate with a diameter larger than the embedded parts 1 can be welded to the bottom of the embedded parts 1, and then the embedded parts 1 are buried. In this way, when filling the soil, the contact area between the embedded parts 1 and the soil layer can be increased, thereby improving the stability of the substation. After the four embedded parts 1 are buried, the four pre-installed parts 2 can be inserted into the corresponding embedded parts 1. Because the connecting plate 3 is welded to the four pre-installed parts 2, after the four pre-installed parts 2 are plugged in and installed, the connecting plate 3 is also installed along with the pre-installed parts 2, and then the base 4 is adjusted to the direction and angle for docking. The four preassembled parts 2 are then inserted into the bolts at the four corners of the base 4 respectively, and are inserted into the embedded parts 1 through the base 4 and the preassembled parts 2. Finally, the four fastening bolts 5 are tightened in sequence to fasten the base 4, the four preassembled parts 2 and the four embedded parts 1 together. It should be noted that when tightening the fastening bolts 5, a diagonal tightening sequence should be adopted. This method can ensure that the embedded parts 1, the preassembled parts 2 and the base 4 are subjected to uniform force in four directions, thereby improving the firmness of the connection and installation of the embedded parts 1, the preassembled parts 2 and the base 4. At this point, the preassembled parts of the substation are installed. Compared with the traditional method of pouring concrete piles, this method can greatly save installation time, increase installation speed, and improve the installation efficiency of the substation, which is convenient for users to use. It provides convenience, and then the substation can be installed. During installation, the power station box 11 is lifted so that the card block 9 at the bottom of the power station box 11 is overlapped on the power-assisting ramp 14 on either side. Then, with the help of the slope on the top of the power-assisting ramp 14, the user can easily push the power station box 11 and drive the card block 9 to be inserted into the corresponding card slot 6. Then, the user continues to push the card block 9 to move and adjust the position of the card block 9 in the card slot 6, wherein the card block 9 will slide on the power-assisting assembly 8, as follows. When installing the substation, that is, when installing the power station box 11, the power station box 11 will first be pressed on the adaptation frame 82 and the rolling rod 83, and then when moving and adjusting the power station box 11, all the rolling rods 83 will roll along to reduce the friction between the power station box 11 and the base 4 when adjusting the power station box 11. To provide assistance for the user's installation work, when the power station box 11 is pressed on the adaptation frame 82 and the rolling rod 83, the adaptation frame 82 and the rolling rod 83 will also move down, thereby driving the sliding rod 84 to move up and down on the fixed frame 81, and at the same time stretching the spring 85, and then the fastening bolt 10 can be inserted to fix the power station box 11, thereby providing convenience for the user's installation work. During the installation of the substation, the substation will slide on multiple rolling rods 83 for adjustment, and the rolling rod 83 will also roll along during the movement of the substation, providing convenience for the user's adjustment work, thereby improving the installation efficiency of the substation. During work, the sliding rod 84 will move down and stretch the spring 85 at the same time, and then when the work is completed, the spring 85 will contract to push the sliding rod 84 back to its original position.In order to prepare for the next work and provide convenience for the user's work, when the hole on the card block 9 is aligned with the hole in the card slot 6, the fastening bolt 10 is inserted and tightened to complete the installation of the substation. In this way, the installation of the substation can be completed quickly in the shortest time, improving the installation efficiency of the substation.

[0028] Therefore, a structural design combining the power station body and embedded parts is adopted. During installation, users can first bury the embedded parts underground, leaving only the part connected to the power station body exposed, and then move the corresponding power station body to the embedded parts and adjust and fix them.
