[0027] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0028] like Figure 1-Figure 8The shown intelligent photovoltaic inverter is easy to maintain, including an inverter body 1, which is an intelligent photovoltaic inverter. The intelligent photovoltaic inverter is a power conversion device using advanced technology, which can efficiently convert the DC power collected by the solar panel into AC power to supply the power grid or independently operated load equipment. A strip seat 2 is fixedly installed on one side of the rear surface of the inverter body 1, and a limit plate 5 is inserted into the rear surface of the strip seat 2 through a first elastic mechanism. A plate seat 4 is fixedly installed on the other side of the rear surface of the inverter body 1. A sleeve frame 9 is rotatably embedded on the rear surface of the plate seat 4, and a plug plate 10 is slidably inserted on the outer surface of the sleeve frame 9. A clamping mechanism is provided at the lower end of the plug plate 10. A plurality of limit holes 20 are penetrated through the outer surface of the plug plate 10. A plug post 18 is slidably penetrated through the rear surface of the sleeve frame 9 through a second elastic mechanism. The rear end of the plug post 18 is slidably inserted into the rear surface of the plate seat 4, and the plug post 18 slides through the inner side of one of the limit holes 20.

[0029] The vertical bracket 28 and the oblique bracket 29 are fixedly mounted on the lower surface of the solar panel 30 , and the lower end of the oblique bracket 29 is fixedly connected to the surface of the vertical bracket 28 to form a triangular structure, thereby ensuring the stability of the installation of the solar panel 30 .

[0030] During use, the strip seat 2 and the limiting plate 5 clamp the surface of the vertical bracket 28 , and the clamping mechanism clamps the surface of the oblique bracket 29 .

[0031] like Figure 1 , Figure 2 As shown, a reinforcement frame 3 is fixedly connected between the strip seat 2 and the plate seat 4, and the rear surface of the inverter body 1 is fixedly connected to the reinforcement frame 3. The reinforcement frame 3 is used to improve the stability between the strip seat 2 and the plate seat 4.

[0032] like Figure 3 As shown, the first elastic mechanism includes a first snap-in groove 7 provided on the inner side of the strip seat 2, the front end of the limit plate 5 is slidably inserted into the inner side of the first snap-in groove 7, and the front end of the limit plate 5 is fixedly connected with a first bent plate 6, the first bent plate 6 is slidably matched with the inner side of the first snap-in groove 7, the rear surface of the first bent plate 6 is fixedly connected with a first compression spring 8, and the rear end of the first compression spring 8 is fixedly connected to the inner surface of the first snap-in groove 7. By moving the limit plate 5 backward, the first bent plate 6 is moved backward, squeezing the first compression spring 8, and then the strip seat 2 and the limit plate 5 can be clamped on the surface of the vertical bracket 28.

[0033] like Figure 4As shown, the clamping mechanism includes an end plate 11 fixedly connected to the lower end of the plug plate 10, a fixed clamping plate 12 is fixedly connected to the front of the lower surface of the end plate 11, a sliding opening 14 is penetrated through the lower surface of the end plate 11, a movable clamping plate 13 is slidably inserted inside the sliding opening 14, and a threaded rod 15 is rotatably penetrated through the rear surface of the end plate 11, the threaded rod 15 passes through the inner side of the sliding opening 14, and the threaded rod 15 threadedly penetrates the surface of the movable clamping plate 13. By rotating the threaded rod 15, the movable clamping plate 13 slides along the inner side of the sliding opening 14, and the distance between the movable clamping plate 13 and the fixed clamping plate 12 is changed, so that it can be adapted to be clamped on the surface of the oblique bracket 29.

[0034] like Figure 5 As shown, the second elastic mechanism includes a second snap-in slot 23 provided on the inner side of the plate-shaped seat 4, an L-shaped plate 16 is slidably inserted into the rear end of the second snap-in slot 23, a second bent plate 25 is fixedly connected to the front end of the L-shaped plate 16, the second bent plate 25 is slidably matched with the inner side of the second snap-in slot 23, a second compression spring 24 is fixedly connected to the rear surface of the second bent plate 25, the rear end of the second compression spring 24 is fixedly connected to the inner surface of the second snap-in slot 23, and the upper end of the second bent plate 25 is fixedly connected to the surface of the plug post 18. A handle 17 is fixedly connected to the rear surface of the L-shaped plate 16. The handle 17 facilitates the user to pull the L-shaped plate 16, which will cause the second bent plate 25 to move backward and squeeze the second compression spring 24.

[0035] like Figure 5 , Figure 6 As shown, a circular groove 26 is formed on the rear surface of the plate-shaped seat 4, an inner ring groove 27 is formed on the inner wall of the circular groove 26, and an extension edge 21 is provided on the edge of the sleeve 9, and the extension edge 21 is slidably inserted into the inner side of the inner ring groove 27. The sleeve 9 can be rotated inside the circular groove 26, and at the same time, it is ensured that the sleeve 9 will not be separated from the inner side of the circular groove 26.

[0036] An insertion hole 19 is formed on the surface of the circular groove 26 , and the front end of the insertion post 18 is slidably inserted into the inner side of the insertion hole 19 .

[0037] During use, the strip seat 2 and the limit plate 5 are clamped on the surface of the vertical bracket 28. Under the elastic force of the first compression spring 8, the limit plate 5 can be clamped on the surface of the vertical bracket 28. Then, the handle 17 is pulled backward to make the plug post 18 leave the plug hole 19 and the sleeve frame 9. Then, the sleeve frame 9 can rotate inside the circular groove 26, that is, the plug plate 10 can rotate. At the same time, the plug plate 10 can slide relatively inside the sleeve frame 9. Through two degrees of freedom adjustment, the plug plate 10 is perpendicular to the oblique bracket 29, and the end plate 11 is as close to the surface of the oblique bracket 29 as possible. After releasing the handle 17, the plug post 18 leaves the plug hole 19 and the sleeve frame 9. The position of the plug plate 10 is adjusted so that the plug post 18 can pass through the inner side of the limiting hole 20, so that the plug plate 10 can be limited. Therefore, it can be used to adapt to the inclination angle of the oblique bracket 29. After releasing the hand, the inverter body 1 moves down slightly, and the end plate 11 will be attached to the surface of the oblique bracket 29. At this time, since the plug plate 10 is fixed, the limiting plate 5 is attached to the side of the vertical bracket 28, so the stability of the inverter body 1 can be guaranteed. Finally, the threaded rod 15 is rotated to move the movable clamping plate 13 backward to cooperate with the fixed clamping plate 12 to clamp the surface of the oblique bracket 29. After installation, the state is as follows Figure 7 , Figure 8 shown.
