Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic panel mounting frame technology, and in particular relates to a sand-proof solar photovoltaic panel mounting frame. Background Technology

[0002] Solar photovoltaic panels are devices that generate electricity using solar energy. They are mainly composed of solid photovoltaic cells made of semiconductor materials. Solar photovoltaic power generation systems are a new type of power generation system that directly converts solar energy into electrical energy. They can operate independently or in grid-connected mode. Before generating electricity, solar photovoltaic panels need to be installed at an angle or horizontally using mounting frames.

[0003] Patent CN219394750U discloses a solar photovoltaic panel mounting frame, comprising: a support frame including two sets of legs arranged at intervals, at least one set of legs being retractable; and a fixing frame including two crossbeams and two longitudinal beams spaced apart between the two crossbeams. The two longitudinal beams are detachably hinged to the two sets of legs, and each of the two crossbeams includes a hinge structure, allowing the fixing frame to bend and fold towards the connection side with the support frame when separated from the support frame. The fixing frame is provided with a mounting section for installing solar photovoltaic panels. Thus, when solar photovoltaic panels need to be installed, the fixing frame can be unfolded and the legs installed on the longitudinal beams of the fixing frame to install the solar photovoltaic panels on the mounting section of the fixing frame, satisfying the need for convenient handling of the mounting frame while also enabling rapid assembly.

[0004] In the existing technology, the mounting frame can be moved by setting a fixed frame and an installation part, but the following problems still exist in the overall use: First, when the mounting frame is installed, it is connected by pre-embedded concrete and bolts. The concrete and bolt connection will be eroded by the friction of wind and sand, causing the connection to loosen and the mounting frame to be prone to collapse. Second, after the existing mounting frame becomes loose, the maintenance personnel need to re-precast the concrete, which makes maintenance difficult and inefficient. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a sand-proof solar photovoltaic panel mounting frame. By setting up a fixed base and protective shell, it can protect the connection of the support columns and prevent wind and sand erosion. This solves the problem that the connection between the mounting frame and the concrete will be eroded by the friction of wind and sand, causing the connection to loosen. By setting up a first positioning column and a threaded sleeve, the two support columns can be tightened by rotating the threaded sleeve when the mounting frame becomes loose. This solves the problem that maintenance personnel need to re-precast concrete after the mounting frame becomes loose, which leads to difficult maintenance and low efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sand-proof solar photovoltaic panel mounting frame, comprising support columns, a fixed base at one bottom end of each of the support columns, two protective shells on the outside of each of the fixed bases, the two protective shells being interlocked, connecting rods on the outer surface of each of the protective shells, each pair of connecting rods forming a group, a tensionable threaded sleeve between each group of connecting rods, a top connecting seat at one top end of each of the support columns, a diagonal rod rotatably connected between the top connecting seats, and a crossbeam rotatably connected on the end face of each top connecting seat, the end face of the crossbeam being used to mount the photovoltaic panel.

[0007] Preferably, the fixed base has a first positioning post inside, which is slidably connected to the support post. The outer surface of the fixed base has multiple fixing holes, and bolts are installed inside the multiple fixing holes.

[0008] Preferably, each of the multiple fixed bases has a wing plate on its top end face, and each of the multiple wing plates has a fixed plate slidably disposed on its bottom end face, and the multiple fixed plates are respectively fixedly connected to the protective shell.

[0009] Preferably, the multiple protective shells are grouped into pairs, with one of the protective shells having a buckle on its outer surface and the other protective shell having a snap-fit ​​hole corresponding to the buckle on its outer surface.

[0010] Preferably, the outer surfaces of the plurality of connecting rods are provided with protrusions, and the plurality of protrusions form grooves on the outside of the connecting rods. Each set of connecting rods can be engaged with each other by the protrusions and grooves, and the bottom end faces of the plurality of connecting rods are provided with a plurality of friction particles.

[0011] Preferably, one side of each connecting rod in each group is provided with a half-cut threaded rod, and every two threaded rods are joined together and threadedly connected to a threaded sleeve, wherein the inner wall of the threaded sleeve is provided with a reverse thread.

[0012] Preferably, a base plate is provided on the end face of each of the plurality of top connecting seats, a hinge is provided on the end face of each of the plurality of base plates, a top plate is provided on the outer surface of each of the plurality of hinges, and a second positioning post is provided on the outer surface of the top plate, the second positioning post being connected to the diagonal rod.

[0013] Preferably, each of the plurality of diagonal braces and the outer surface of the support column is provided with a connector, and a first telescopic rod is rotatably provided between the plurality of connectors.

[0014] Preferably, a connecting block is rotatably provided on the outer surface of the plurality of threaded sleeves, and a second telescopic rod is rotatably provided on the outer surface of the connecting block, with one end of the second telescopic rod rotatably connected to the crossbeam.

[0015] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0016] (1) By setting a fixed base and a protective shell, as well as a fixed plate and a support column, this utility model can protect the connection of the support column, prevent wind and sand erosion, improve the overall stability and safety of the mounting frame, and by setting a fixed plate, prevent the support column from sliding upward, thereby improving the stability of the protective shell.

[0017] (2) By setting the first positioning column and connecting rod, as well as the protrusion and threaded sleeve, the protrusions can be interlocked to prevent the protective shell from sliding laterally, thereby further improving the stability of the protective shell. At the same time, by setting the threaded rod and threaded sleeve, when the mounting frame becomes loose, the two threaded rods can be brought closer together by rotating the threaded sleeve, tightening the two support columns, making the connection between the mounting frame and the concrete tighter, eliminating the need for re-precast concrete, thereby improving maintenance efficiency.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A sand-resistant solar photovoltaic panel mounting frame includes support columns 10. Each support column 10 has a fixed base 11 at one bottom end. A first positioning post 23 is located inside the fixed base 11, and the first positioning post 23 is slidably connected to the support column 10. Multiple fixing holes 24 are provided on the outer surface of the fixed base 11, and bolts are installed inside the fixing holes 24. During installation, the support column 10 is inserted into the outside of the first positioning post 23. The outer surface of the support column 10 has holes for installing bolts. The bolt holes of the support column 10 are aligned with the fixing holes 24, and then bolts are used to pass through the fixed base 11, support column 10, and first positioning post 23 for fixing, thereby fixing the support column 10 to the fixed base 11. The outer surface of the fixed base 11 has waist holes, which can be used to connect the fixed base 11 to precast concrete using reinforcing bolts, thus completing the installation of the support column 10. It should be noted that precast concrete is existing technology; before installation, the precast concrete has already been fixed and embedded in the predetermined position.

[0028] Further reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 Each of the multiple fixed bases 11 has a wing plate 20 on its top end face. Each of the multiple fixed bases 11 has two protective shells 12 on its exterior. Each of the two protective shells 12 has a fixing plate 19 on its inner wall. The multiple fixing plates 19 and the inner wall of the protective shells 12 form a sliding track. The sliding track is slidably connected to the wing plate 20. The multiple protective shells 12 are in pairs. One of the protective shells 12 has a buckle 22 on its outer surface. The other protective shell 12 has a snap-fit ​​hole on its outer surface corresponding to the buckle 22. The two protective shells 12 can be fastened to each other through the buckle 22 and the snap-fit ​​hole. By fastening the two protective shells 12, the fixed base 11 can be protected to prevent wind and sand from eroding the connection between the fixed base 11 and the precast concrete, thereby protecting the surface of the concrete and improving the stability of the fixed base 11.

[0029] refer to Figure 1 , Figure 2 , Figure 5 and Figure 6Multiple protective shells 12 have connecting rods 25 on their outer surfaces. Each pair of connecting rods 25 forms a group, and each pair of connecting rods 25 in a group has a threaded rod 28 on one side. Each pair of threaded rods 28 has a threaded sleeve 29 rotatably mounted on its outer surface. The two threaded rods 28 are threadedly connected to the threaded sleeves 29 respectively. It should be noted that each of the two threaded rods 28 has only half of its threaded surface. After the two are fitted together, they form a complete threaded rod. In this application, the threaded rod is first integrally threaded and then cut into two sides by high-precision wire cutting. This ensures that the threaded rod can cooperate with the threaded sleeve 29 when the two sides are cut and then joined together. The specific processing technology is existing technology and will not be elaborated on in this solution.

[0030] The inner wall of the threaded sleeve 29 is provided with reverse threads. By rotating the threaded sleeve 29, it can cooperate with the external thread surfaces of the two merged threaded rods 28, thereby driving the connecting rods 25 at both ends and the protective shell 12 to be tightly fitted together, and driving the fixed base 11 inside the protective shell 12 to be tightly fitted together, thereby tightening the two support columns 10 and preventing the support columns 10 from loosening. The outer surface of the multiple connecting rods 25 is provided with multiple protrusions 26 along a straight direction. The multiple protrusions 26 form grooves on the outside of the connecting rods 25, and each set of connecting rods 25 can pass through... The protrusions 26 and grooves engage with each other. By engaging multiple protrusions 26 and grooves, when the rotating threaded sleeve 29 pulls the connecting rod 25, it can drive another connecting rod 25 through the protrusions 26, so that the two protective shells 12 move together, preventing the displacement of a single protective shell 12 and damage. Multiple friction particles 27 are provided on the bottom end face of multiple connecting rods 25. By setting friction particles 27, the friction between the connecting rod 25 and the ground can be increased, and the support column 10 can be supported, thereby improving the overall stability of the mounting frame.

[0031] Further reference Figure 2 , Figure 3 and Figure 7Each of the multiple support columns 10 has a top connecting seat 37 at one end. The top connecting seat 37 has the same structure as the fixed base 11. Each of the multiple top connecting seats 37 has a base plate 33 on its end face. Each of the multiple base plates 33 has a hinge 34 on its end face. Each of the multiple hinges 34 has a top plate 35 on its outer surface. Each top plate 35 has a second positioning post 36 on its outer surface. Each second positioning post 36 has a diagonal rod 15 on its outer surface. The second positioning post 36 facilitates the positioning of the diagonal rod 15, making installation easier and improving installation efficiency. The diagonal rod 15 is fixedly connected to the second positioning post 36. Chain 34 and top plate 35 can adjust the angle of diagonal bar 15, thereby improving the flexibility of the device. A crossbeam 16 is provided on the top end face of top plate 35. The top end face of crossbeam 16 is used to install photovoltaic panels. Multiple fasteners 17 are provided on the top end face of crossbeam 16. The multiple fasteners 17 can fix the photovoltaic panels and improve the stability of the photovoltaic panels. A buffer damper 32 is provided between bottom plate 33 and top plate 35. When the photovoltaic panels are impacted by strong winds or other severe weather, the buffer damper 32 can provide buffering capacity to prevent vibration from damaging the bottom connection structure, thereby improving the overall stability of the device.

[0032] Further reference Figure 2 , Figure 3 and Figure 7 Multiple diagonal braces 15 and support columns 10 are provided with connecting parts 13 on their outer surfaces. A first telescopic rod 14 is rotatably connected between the multiple connecting parts 13. The first telescopic rod 14 can support the diagonal braces 15, thereby improving the stability of the diagonal braces 15. Multiple threaded sleeves 29 are rotatably provided with connecting blocks 30 on their outer surfaces. A second telescopic rod 31 is rotatably provided with the outer surface of the connecting blocks 30. One end of the second telescopic rod 31 is rotatably connected to the crossbeam 16. The second telescopic rod 31 can support the crossbeam 16, thereby improving the stability of the crossbeam 16.
