Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel steel frame technology, and in particular to a round tube plug-in photovoltaic panel steel frame. Background Technology

[0002] A photovoltaic (PV) panel (also known as a solar photovoltaic panel) is a power generation device that directly converts sunlight into direct current through semiconductor materials (such as silicon). When using PV panels, they are usually installed on a steel frame, so that the PV panels are a certain distance from the ground.

[0003] A search revealed a patent with application number CN201720242824.9, which discloses a steel frame for a photovoltaic solar power station with plug-in circular steel pipes. In this design, when two circular steel pipe frames are spliced ​​together, both frames have numerous holes for connection using bolts or pins. However, at the ends of the spliced ​​two circular pipes, when the insertion distance is too small, the ends of the two circular pipes will experience very high stress. The relatively thin thickness of the circular pipes will cause twisting at the spliced ​​ends. Additionally, the numerous holes weaken the strength of the circular pipes. Therefore, a steel frame for photovoltaic panels with plug-in circular pipes is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a circular tube plug-in photovoltaic panel steel frame to solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A circular tube plug-in photovoltaic panel steel frame includes a first circular tube steel frame and a second circular tube steel frame. The first circular tube steel frame has a plug-in end at its end, which is plugged into the end of the second circular tube steel frame. The end of the second circular tube steel frame is welded with a protective outer sleeve. One end of the protective outer sleeve is fitted over the outside of the first circular tube steel frame and fixedly connected by a connecting assembly. Both ends of the first and second circular tube steel frames are equipped with end sleeves through an installation assembly. Side supports are installed on the end sleeves, and rotation positioning components are provided on the side supports. The rotation positioning components are connected to the end sleeves.

[0007] Preferably, the connecting assembly includes a plug-in connection hole on the first circular steel frame, a plug-in fixing hole on the protective outer sleeve, a plug-in connection bolt installed on the plug-in connection hole and the plug-in fixing hole, and a nut on the plug-in connection bolt.

[0008] Preferably, the mounting assembly includes an end insertion groove formed at the end of the end sleeve, and the ends of the first round steel frame and the second round steel frame are respectively inserted into the two end insertion grooves.

[0009] Preferably, both the first and second circular tube steel frames are provided with end positioning holes, the end sleeve is provided with mounting positioning holes, and positioning bolts are provided on the end positioning holes and the mounting positioning holes.

[0010] Preferably, the rotary positioning assembly includes a fixed frame fixedly installed on the side of the side bracket, two positioning columns are movably installed on the fixed frame, and multiple positioning grooves are opened on the side of the end sleeve, with one end of the two positioning columns extending into the corresponding two positioning grooves.

[0011] Preferably, a connecting plate is fixedly installed at one end of each of the two positioning columns, and a tension spring is fixedly installed between the connecting plate and the fixing frame.

[0012] Preferably, the number of positioning slots is even, the end sleeve is rotatably mounted on the side bracket, and photovoltaic panel placement plates are installed on both the first and second round tube steel frames.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The protective outer sleeve of the circular tube plug-in photovoltaic panel steel frame, which is fitted at the connection between the first and second circular tube steel frames, can increase the stability and durability of the connection between the two circular tube steel frames and prevent the plug-in end from deforming or twisting under the weight. The end sleeve can strengthen the protection of the ends of the first and second circular tube steel frames and prevent the problems of rust and deformation and unstable end connection after long-term pipe connection.

[0014] The rotating positioning component allows for angle adjustment of the end sleeve, enabling adjustment of the installed photovoltaic panel's angle and position. The positioning post is locked in the positioning groove, stabilizing the photovoltaic panel after adjustment. Angle adjustment is relatively convenient. The design avoids setting too many holes in the first and second circular steel frames, reducing the time and steps required for drilling. At the same time, fewer holes increase the rigidity and strength of the first and second circular steel frames, extending their service life. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Refer to Figure 1-5 A circular tube plug-in photovoltaic panel steel frame includes a first circular tube steel frame 1 and a second circular tube steel frame 2. The first circular tube steel frame 1 has a plug-in end 4 at one end, which is plugged into the end of the second circular tube steel frame 2. A protective outer sleeve 3 is welded to the end of the second circular tube steel frame 2. One end of the protective outer sleeve 3 is fitted over the outside of the first circular tube steel frame 1 and fixedly connected using a connecting assembly. Both ends of the first and second circular tube steel frames 1 and 2 are fitted with end sleeves 9 via mounting assemblies. The connecting assembly includes a plug-in connection hole 5 on the first circular tube steel frame 1 and a plug-in fixing hole 6 on the protective outer sleeve 3. Plug-in connection bolts 7 are installed on the plug-in connection holes 5 and 6, and the plug-in connection bolts 7 are equipped with... A nut is used to insert the plug end 4 of the first round steel frame 1 into the second round steel frame 2. A protective outer sleeve 3 is welded or bolted to the end of the second round steel frame 2. The protective outer sleeve 3 is fitted onto the connection between the first round steel frame 1 and the second round steel frame 2. The outer sleeve is equipped with a pipe, which can increase the stability and durability of the connection between the two round steel frames and prevent the plug end 4 from deforming or twisting when bearing weight. The plug connection bolt 7 can realize the stable connection between the protective outer sleeve 3 and the first round steel frame 1. A side bracket 8 is installed on the end sleeve 9. A rotation positioning component is provided on the side bracket 8 and connected to the end sleeve 9.

[0023] Furthermore, the installation assembly includes an end insertion groove 10 formed at the end of the end sleeve 9. The ends of the first circular steel frame 1 and the second circular steel frame 2 are respectively inserted into the two end insertion grooves 10. Both the first circular steel frame 1 and the second circular steel frame 2 are provided with end positioning holes 11, and the end sleeve 9 is provided with mounting positioning holes 12. Positioning bolts 13 are provided on the end positioning holes 11 and the mounting positioning holes 12. The end sleeve 9 is connected to the ends of the first circular steel frame 1 and the second circular steel frame 2. The positioning bolts 13 are provided to achieve the positioning connection between the end sleeve 9 and the first circular steel frame 1 and the second circular steel frame 2. The end sleeve 9 can strengthen the protection of the ends of the first circular steel frame 1 and the second circular steel frame 2, and avoid the problems of rust and deformation and unstable end connection after long-term pipe connection.

[0024] Furthermore, the rotary positioning assembly includes a fixed frame 14 fixedly installed on the side of the side bracket 8. Two positioning posts 15 are movably installed on the fixed frame 14. Multiple positioning slots 18 are opened on the side of the end sleeve 9. One end of the two positioning posts 15 extends into the corresponding two positioning slots 18. A connecting plate 16 is fixedly installed on one end of the two positioning posts 15. A tension spring 17 is fixedly installed between the connecting plate 16 and the fixed frame 14. The number of positioning slots 18 is even. The end sleeve 9 is rotatably installed on the side bracket 8. Photovoltaic panel placement plates 19 are installed on both the first circular steel frame 1 and the second circular steel frame 2. The end sleeve 9 can be rotatably installed on the side bracket 8. The rotary positioning assembly pulls the connecting plate 16 to move, thereby driving... Once the positioning post 15 disengages from the positioning groove 18, the end sleeve 9 can be rotated, thereby rotating the first circular steel frame 1 and the second circular steel frame 2. This allows the position of the photovoltaic panel placement plate 19 to be adjusted, thus adjusting the angle of the placed photovoltaic panel. After the position is adjusted, the connecting plate 16 is released, and under the elastic force of the tension spring 17, the positioning post 15 is moved into the positioning groove 18, achieving a stable connection. Angle adjustment is relatively convenient. During installation and adjustment, not many holes are set on the first circular steel frame 1 and the second circular steel frame 2, avoiding the need to drill too many holes in the first circular steel frame 1 and the second circular steel frame 2. At the same time, reducing the hole diameter increases the rigidity of the first circular steel frame 1 and the second circular steel frame 2, increasing their service life.

[0025] During use: When installing the photovoltaic panel steel frame, the insertion end 4 of the first circular steel frame 1 is inserted into the second circular steel frame 2. A protective outer sleeve 3 is installed at the connection between the first and second circular steel frames 1 and 2, with an external pipe covering it. This increases the stability and durability of the connection between the two circular steel frames, preventing the insertion end 4 from deforming or twisting under load. End sleeves 9 are connected to the ends of both the first and second circular steel frames 1 and 2. These end sleeves allow for proper support and protection of the first and second circular steel frames. The ends of frame 2 are reinforced to prevent corrosion and deformation after long-term pipe connection, and to prevent unstable end connection. Pulling the connecting plate 16 moves the positioning column 15 out of the positioning groove 18, and the end sleeve 9 can be rotated to adjust the angle of the photovoltaic panel placement plate 19. The adjustment is relatively convenient. The design does not set too many holes on the first round tube steel frame 1 and the second round tube steel frame 2, which reduces the drilling time. At the same time, the reduction in hole diameter increases the rigidity of the first round tube steel frame 1 and the second round tube steel frame 2, extends the service life, and makes it convenient to use.
