Description

Technical Field

[0001] This utility model relates to an inverter installation structure, belonging to the photovoltaic field. Background Technology

[0002] In the construction phase of photovoltaic projects, inverter installation is a crucial step in ensuring efficient power conversion. Construction workers select high-strength bolts of the appropriate specifications and thread them sequentially through the pre-drilled mounting holes on the inverter and the bracket. With the orderly tightening of power tools, the bolts, through their powerful clamping force, firmly secure the inverter to the bracket, forming a reliable connection structure and laying a solid foundation for subsequent stable power conversion operations. Considering the certain height of the photovoltaic brackets, the current inverter installation process typically requires two people. In practice, one worker must manually lift the inverter to a suitable height and continuously adjust its position to ensure precise alignment between the inverter's mounting holes and the holes on the bracket; the other worker simultaneously assembles and tightens the bolts. This traditional installation method not only demands high levels of physical strength and coordination from the workers but also requires double the manpower, significantly increasing the labor costs of photovoltaic project construction. This labor consumption problem is particularly prominent in large-scale construction scenarios. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an inverter installation structure to solve the problems mentioned in the background technology. This utility model enables a single person to install the inverter on the bracket, saving labor costs.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an inverter mounting structure includes a crossbeam with legs mounted at both ends. A long screw threaded through the crossbeam is connected to the middle of the crossbeam. A detachable short screw is mounted at the lower end of the long screw, and a connecting plate is rotatably mounted at the lower end of the short screw. An inverter is provided on one side of the connecting plate, and the upper end of the inverter is connected to the connecting plate by bolts. Support arms are mounted on both legs, and the support arms are connected to the lower end of the inverter by bolts.

[0005] Furthermore, the long screw has multiple insertion holes equidistant from top to bottom, and a handle is inserted into one of the insertion holes, the diameter of which is the same as the inner diameter of the insertion hole.

[0006] Furthermore, a vertical hole is provided at the middle of the upper surface of the crossbeam, and a threaded sleeve is provided on the upper side of the vertical hole, which is concentrically arranged with the vertical hole. The threaded sleeve is connected to the crossbeam by fasteners formed by screws and nuts. The structure formed by the long screw and the short screw is threadedly connected in the threaded sleeve, and the structure formed by the long screw and the short screw passes through the vertical hole.

[0007] Furthermore, the lower end of the threaded sleeve is connected and fixed with two symmetrically arranged lugs, and the screw passes through the lugs and the crossbeam and is threadedly connected with a nut.

[0008] Furthermore, two symmetrically arranged L-shaped plates are installed on the lower surface of the crossbeam, the lower end of the screw penetrates the horizontal part of the L-shaped plate, and the nut is located on the lower side of the horizontal part of the L-shaped plate.

[0009] Furthermore, the upper surface of the short screw is recessed downward to form a rectangular hole, and the lower end of the long screw is equipped with a rectangular head that mates with the rectangular hole. The outer surface of the upper end of the short screw is provided with a countersunk screw hole, and the countersunk screw hole is internally threaded with an internal hex bolt for confining the rectangular head within the rectangular hole.

[0010] Furthermore, a lug is installed at the center of the side of the connecting plate facing away from the inverter. The lower end of the short screw passes through the lug. Limiting rings that slide in contact with the lug are provided on the upper and lower sides of the lug. The limiting rings are sleeved on the short screw and connected and fixed to the short screw.

[0011] Furthermore, both ends of the crossbeam are connected and fixed with a first reinforcing rib, and the end of the first reinforcing rib away from the crossbeam is connected and fixed to the support leg.

[0012] Furthermore, a second reinforcing rib is installed between the support arm and the support leg, and the second reinforcing rib is arranged in an inclined manner.

[0013] Furthermore, a base is fixedly connected to the lower end of the support leg, and two third reinforcing ribs are installed between the base and the support leg.

[0014] The beneficial effects of this utility model are:

[0015] a. First, connect the structure formed by the long and short screws to the crossbeam via threads. Then, lower the short screw to a position close to the ground. Next, use bolts to connect the connecting plate rotatably connected to the lower end of the short screw to the upper end of the inverter. This allows the assembly of the structure formed by the short and long screws and the inverter to be completed on the ground. Then, rotate the structure formed by the long and short screws to connect the short screw to the crossbeam via threads. Finally, remove the long screw, allowing for its repeated use. Use bolts to connect the lower end of the inverter to the support arm, thus restricting the inverter's position. The entire process requires only one person to operate, eliminating the need for multiple people, significantly reducing labor costs and greatly improving the efficiency of photovoltaic construction.

[0016] b. The threaded sleeve is installed on the crossbeam using fasteners formed by screws and nuts, thus assembling the threaded sleeve and the crossbeam. This makes it convenient to install the threaded sleeve, which is used to install the long screw and short screw structure, on the crossbeam only when installing the inverter. Compared with directly machining screw holes on the crossbeam, this method avoids small debris from entering the threaded grooves during the movement of the crossbeam, which could affect the assembly of the long screw and short screw structure.

[0017] c. After the lower end of the screw passes through the horizontal part of the L-shaped plate, tighten the nut. Due to the restriction of the L-shaped plate, there is a gap between the nut and the crossbeam. If the short screw and threaded sleeve cannot be easily separated later, affecting the maintenance or replacement of the inverter, the inverter can be separated from the crossbeam by cutting the screw using the gap between the L-shaped plate and the crossbeam. During the construction process, there is also a gap between the support arm and the lower end of the inverter, which limits the bolts of the support arm and the lower end of the inverter to a partially exposed state, providing space for cutting the bolts connecting the support arm and the inverter.

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1 and Figure 2 This utility model provides a technical solution: an inverter mounting structure, including a crossbeam 1, with legs 2 installed at both ends of the crossbeam 1, and first reinforcing ribs 3 fixedly connected to both ends of the crossbeam 1, so that the end of the first reinforcing rib 3 away from the crossbeam 1 is fixedly connected to the legs 2 to improve the mechanical strength of the connection between the crossbeam 1 and the legs 2. Second reinforcing ribs 4 are installed between the support arm 5 and the legs 2 in an inclined manner to improve the mechanical strength of the connection between the support arm 5 and the legs 2. A base 7 is fixedly connected to the lower end of the legs 2. By installing two third reinforcing ribs 6 between the base 7 and the legs 2, the mechanical strength of the connection between the legs 2 and the base 7 is improved. The structure formed by the base 7, legs 2, support arm 5 and crossbeam 1 together constitutes a bracket for limiting the position of the inverter.

[0026] See Figures 1-4 A long threaded rod 13 is threaded through the middle of the crossbeam 1. A detachable short threaded rod 10 is installed at the lower end of the long threaded rod 13. The upper surface of the short threaded rod 10 is recessed downward to form a rectangular hole 20. A rectangular head 19 that mates with the rectangular hole 20 is installed at the lower end of the long threaded rod 13. A countersunk threaded hole is formed on the outer surface of the upper end of the short threaded rod 10. An internal hex bolt 21 is threaded into the countersunk threaded hole to restrict the rectangular head 19 within the rectangular hole 20. The internal hex bolt 21 can be removed. After bolt 21 is engaged, the long screw 13 and the short screw 10 can be separated. A connecting plate 9 is rotatably mounted on the lower end of the short screw 10. A lug is installed in the middle of the side of the connecting plate 9 facing away from the inverter 8. The lower end of the short screw 10 passes through the lug. Limiting rings that slide in contact with the lug are provided on the upper and lower sides of the lug. The limiting rings are sleeved on the short screw 10 and connected and fixed to the short screw 10. Under the restriction of the limiting rings, the relative position of the short screw 10 and the connecting plate 9 is restricted. One side of the connecting plate 9 is provided with The system includes an inverter 8, the upper end of which is connected to a connecting plate 9 via bolts. Support arms 5 are mounted on both legs 2, and these arms 5 are bolted to the lower end of the inverter 8. First, the structure formed by the long screw 13 and the short screw 10 is threadedly connected to the crossbeam 1. Then, the short screw 10 is lowered to a position close to the ground. Bolts are then used to connect the connecting plate 9, which is rotatably connected to the lower end of the short screw 10, to the upper end of the inverter 8. This allows the assembly of the structure formed by the short screw 10 and the long screw 13 with the inverter 8 to be completed on the ground. The structure formed by the long screw 13 and the short screw 10 is then rotated to thread the short screw 10 to the crossbeam 1. The long screw 13 is then removed, allowing for its repeated use. Bolts are used to connect the lower end of the inverter 8 to the support arm 5, thus restricting the position of the inverter 8. The entire process requires only one person to operate, eliminating the need for multiple people, significantly reducing labor costs and greatly improving the efficiency of photovoltaic construction.

[0027] See Figures 1-4The long screw 13 has multiple insertion holes 14 evenly spaced from top to bottom. A handle 12 is inserted into one of the insertion holes 14. The diameter of the handle 12 is the same as the inner diameter of the insertion hole 14, so that the handle 12 is inserted into the multiple insertion holes 14 on the long screw 13 one by one, making it convenient for people to stand on the ground and use the handle 12 to turn the long screw 13.

[0028] See Figures 1-4 A vertical hole is provided at the center of the upper surface of the crossbeam 1. A threaded sleeve 11 is provided on the upper side of the vertical hole, concentrically arranged with the vertical hole. The threaded sleeve 11 is connected to the crossbeam 1 by a fastener formed by a screw 18 and a nut 15. A structure formed by a long screw 13 and a short screw 10 is threadedly connected inside the threaded sleeve 11. The structure formed by the long screw 13 and the short screw 10 passes through the vertical hole. Two symmetrically arranged ear plates 17 are fixedly connected to the lower end of the threaded sleeve 11. The screw 18 passes through the ear plates 17 and the crossbeam 1 and is threadedly connected to the nut 15. Two symmetrically arranged L-shaped plates 16 are installed on the lower surface of the crossbeam 1. The lower end of the screw 18 passes through the horizontal part of the L-shaped plate 16. The nut 15 is located on the lower side of the horizontal part of the L-shaped plate 16. The threaded sleeve 11 is installed on the crossbeam 1 by the fastener formed by the screw 18 and the nut 15, realizing the assembly of the threaded sleeve 11 and the crossbeam 1. This facilitates the installation of the inverter 8 on the crossbeam 1. The threaded sleeve 11, used to install the structure formed by the long screw 13 and the short screw 10, eliminates the problem of small debris entering the threaded grooves during the movement of the crossbeam 1, which would affect the assembly of the structure formed by the long screw 13 and the short screw 10, compared to directly machining the screw hole on the crossbeam 1. After the lower end of the screw 18 passes through the horizontal part of the L-shaped plate 16, the nut 15 is screwed on. Under the restriction of the L-shaped plate 16, there is a gap between the nut 15 and the crossbeam 1. If the short screw 10 and the threaded sleeve 11 cannot be separated smoothly in the future, affecting the maintenance or replacement of the inverter 8, the screw 18 can be cut off by using the gap between the L-shaped plate 16 and the crossbeam 1 to separate the inverter 8 from the crossbeam 1. During the construction process, there is also a gap between the support arm 5 and the lower end of the inverter 8, which limits the bolts at the lower end of the support arm 5 and the inverter 8 to a partially exposed state, providing space for cutting off the bolts connecting the support arm 5 and the inverter 8.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
