Description

Technical Field

[0001] The present invention relates to the technical field of inverters, and particularly to an intelligent photovoltaic inverter that is convenient for maintenance. Background Art

[0002] An intelligent photovoltaic inverter is a power conversion device using advanced technologies. It can efficiently convert the DC electrical energy collected by solar panels into AC electrical energy for supplying the power grid or independent load devices. The working principle of the intelligent photovoltaic inverter is mainly based on electronic integration technology and digital control technology. When sunlight shines on the solar panels, photons interact with electrons to generate DC current. This DC current first flows into the DC busbar box. After protection and control, it enters the photovoltaic inverter. The inverter uses power transistor electronic components and, under the control of a microprocessor, adopts PWM technology or SPWM technology to rectify and filter the DC power, and through the conversion of the intermediate DC busbar, finally outputs high-quality AC power.

[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 in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0028] As Figures 1 - 8An intelligent photovoltaic inverter that is easy to maintain is shown, including an inverter main body 1. The inverter main body 1 is the intelligent photovoltaic inverter. The intelligent photovoltaic inverter is a power conversion device using advanced technology, which can efficiently convert the DC electrical energy collected by solar panels into AC electrical energy for supplying the power grid or independent load devices. On one side of the rear surface of the inverter main body 1, a strip-shaped seat 2 is fixedly installed. The rear surface of the strip-shaped seat 2 is inserted with a limiting plate 5 through a first elastic mechanism. On the other side of the rear surface of the inverter main body 1, a plate-shaped seat 4 is fixedly installed. A sleeve 9 is rotatably embedded on the rear surface of the plate-shaped seat 4. An insertion plate 10 is slidably inserted on the outer surface of the sleeve 9. A clamping mechanism is arranged at the lower end of the insertion plate 10. A number of limiting holes 20 are penetrated through the outer surface of the insertion plate 10. A plug post 18 is slidably penetrated through the rear surface of the sleeve 9 through a second elastic mechanism. The rear end of the plug post 18 is slidably inserted into the rear surface of the plate-shaped seat 4, and the plug post 18 slidably passes through the inside of one of the limiting holes 20;

[0029] A vertical support 28 and an inclined support 29 are fixedly installed on the lower surface of the solar panel 30. The lower end of the inclined support 29 is fixedly connected to the surface of the vertical support 28, forming a triangular structure, which ensures the stability of the installation of the solar panel 30.

[0030] In use, the strip-shaped seat 2 and the limiting plate 5 clamp the surface of the vertical support 28, and the clamping mechanism clamps the surface of the inclined support 29.

[0031] Such as Figure 1 、 Figure 2 As shown, a reinforcing frame 3 is fixedly connected between the strip-shaped seat 2 and the plate-shaped seat 4. The rear surface of the inverter main body 1 is fixedly connected to the reinforcing frame 3. The reinforcing frame 3 is used to improve the stability between the strip-shaped seat 2 and the plate-shaped seat 4.

[0032] Such as Figure 3 As shown, the first elastic mechanism includes a first clamping groove 7 opened inside the strip-shaped seat 2. The front end of the limiting plate 5 is slidably inserted into the inside of the first clamping groove 7, and a first bent plate 6 is fixedly connected to the front end of the limiting plate 5. The first bent plate 6 is slidably matched with the inside of the first clamping groove 7. A first compression spring 8 is fixedly connected to the rear surface of the first bent plate 6. The rear end of the first compression spring 8 is fixedly connected to the inner surface of the first clamping groove 7. By moving the limiting plate 5 backward, the first bent plate 6 is moved backward, squeezing the first compression spring 8, and then the strip-shaped seat 2 and the limiting plate 5 can be clamped on the surface of the vertical support 28.

[0033] Such as 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 L-shaped plate 16 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] In use, the strip-shaped base 2 and the limit plate 5 are clamped on the surface of the vertical support 28. Under the elastic force of the first compression spring 8, the limit plate 5 can be clamped on the surface of the vertical support 28. Then, pull the handle 17 backward so that the plug post 18 leaves the jack 19 and the sleeve 9. Then, the sleeve 9 can rotate inside the circular groove 26, that is, the insertion plate 10 can rotate. At the same time, the insertion plate 10 can slide relatively inside the sleeve 9. Through the adjustment of two degrees of freedom, the insertion plate 10 is perpendicular to the inclined support 29, and the end plate 11 is as close as possible to the surface of the inclined support 29. After releasing the hand, finely adjust the position of the insertion plate 10 so that the plug post 18 can pass through the inside of the limit hole 20, and the limitation of the insertion plate 10 can be completed. Therefore, it can be used in adaptation to the inclination angle of the inclined support 29. After releasing the hand, the inverter main body 1 moves slightly downward, and the end plate 11 will stick to the surface of the inclined support 29. At this time, since the insertion plate 10 is fixed and the limit plate 5 sticks to the side of the vertical support 28, the stability of the inverter main body 1 can be ensured. Finally, rotate the threaded rod 15, and the movable clamping plate 13 can be moved backward to cooperate with the fixed clamping plate 12 to clamp the surface of the inclined support 29. After installation, the state is as Figure 7 , Figure 8 shown.
