Description

Technical Field

[0001] The utility model relates to the field of photovoltaic brackets, and particularly relates to an anti-wind photovoltaic bracket assembly structure. Background Technique

[0002] With the development of green resources, more and more photovoltaic panels are laid. Photovoltaic panels need to be assisted in installation and fixation by photovoltaic brackets. The photovoltaic brackets are mainly composed of rectangular purlins, M-shaped brackets, main frames, and installation clamps. The photovoltaic panels are installed at the top of the M-shaped brackets through the installation clamps. The M-shaped brackets are fixedly installed at the top of the rectangular purlins through screws, and the purlins are fixedly installed on the main frame through full welding.

[0003] In coastal areas, there are often strong wind weather such as typhoons, so the thickness of the rectangular purlins will be increased, usually 2.5mm thick hollow square steel. However, the bottom plate of the M-shaped bracket is fixed to the purlin through screws, and the thread of the screw has a short connection length with the M-shaped bracket and the purlin. When strong wind weather comes, in addition to its own load, the photovoltaic bracket also has wind load, and the force is gradually transmitted to the screw part. However, there are only a few threads of connection for the screw, which will cause the screw to be pulled out by the huge wind force, causing the photovoltaic panel to be blown off and damaging the photovoltaic panel. Summary of the Invention

An installation bracket for installing the photovoltaic panel is arranged at the bottom of the photovoltaic panel. A transverse purlin for installing the installation bracket is arranged at the bottom of the installation bracket, and further includes:

[0006] Fixing screws are arranged at the top of the transverse purlin and are used for fixedly connecting the installation bracket and the transverse purlin;

[0007] A stabilizer is arranged inside the transverse purlin and is used to increase the screw connection length of the transverse purlin;

[0015] The technical effects and advantages of the present utility model:

Detailed Embodiment

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides an anti-wind and photovoltaic support assembly structure as shown in Figures 1-4 Figure 1, which is applied to a photovoltaic support frame 1. A photovoltaic panel 3 for power generation is provided at the top of the photovoltaic support frame 1. An installation bracket 4 for installing the photovoltaic panel 3 is provided at the bottom of the photovoltaic panel 3. A horizontal purlin 2 for installing the installation bracket 4 is provided at the bottom of the installation bracket 4. The structure further includes:

[0024] A fixing screw 6 is provided at the top of the horizontal purlin 2, and the fixing screw 6 is used for fixedly connecting the installation bracket 4 and the horizontal purlin 2;

[0025] A stabilizer 7 is provided inside the horizontal purlin 2, and the stabilizer 7 is used to increase the length of the screw connection of the horizontal purlin 2;

[0026] An auxiliary member 8 is provided at the bottom of the stabilizer 7, and the auxiliary member 8 is used to support the stabilizer 7.

[0027] Specifically, the vertical cross-section of the horizontal purlin 2 is rectangular. A rectangular groove is provided inside the horizontal purlin 2. Both the stabilizer 7 and the auxiliary member 8 are inserted into the rectangular groove. The top of the photovoltaic support frame 1 is fixedly connected to the bottom of the horizontal purlin 2. An installation clamp 5 for fixing the photovoltaic panel 3 is provided at the top of the installation bracket 4.

[0028] Furthermore, the photovoltaic panel 3 is an existing solar photovoltaic power generation panel. The photovoltaic support frame 1, the horizontal purlin 2, and the installation bracket 4 form an installation frame body for the existing power generation panel. The photovoltaic panel 3 is placed at the top of the installation bracket 4 and is clamped and fixed by the installation clamp 5. The installation clamp 5 and the installation bracket 4 are fixed by bolts. The installation clamp 5 is a special clamp for installing the existing photovoltaic panel 3. The top of the installation clamp 5 is installed on the side of the photovoltaic panel 3 by means of clamping. The connection between the photovoltaic support frame 1 and the horizontal purlin 2 is fixed by full welding. The installation bracket 4 is an existing bracket with a vertical cross-section in the shape of an M. The horizontal purlin 2 is an existing rectangular square steel with a thickness of 2.5 mm. The fixing screw 6 passes through the side of the installation bracket 4 and the top of the horizontal purlin 2 to fixedly install the horizontal purlin 2 and the installation bracket 4.

[0029] Specifically, the stabilizer 7 includes a growth plate 71. A threaded groove 72 is formed at the top end of the growth plate 71. The fixing screw 6 is threadedly inserted into the threaded groove 72. Limiting plates 73 are fixedly connected to both ends of the growth plate 71 respectively. The vertical cross-section of the growth plate 71 and the limiting plates 73 is T-shaped. The auxiliary member 8 includes a supporting cross plate 81. The stabilizer 7 is arranged at the top end of the supporting cross plate 81. Supporting vertical plates 82 are symmetrically arranged at the bottom end of the supporting cross plate 81. The vertical cross-section of the supporting cross plate 81 and the supporting vertical plates 82 is π-shaped.

[0030] Furthermore, inside each transverse purlin 2 for connecting with the mounting bracket 4, a stabilizer 7 and an auxiliary member 8 are arranged. The growth plate 71 is a vertical plate, and the limiting plate 73 is a horizontal plate. The contacting part between the growth plate 71 and the limiting plate 73 is fixed by welding. The growth plate 71 and the symmetrically arranged limiting plates 73 form a T shape. The sum of the widths of the two limiting plates 73 and the width of the growth plate 71 is adapted to the width inside the transverse purlin 2. The position of the growth plate 71 is directly below the position where the fixing screw 6 is installed on the transverse purlin 2. Therefore, after the fixing screw 6 passes through the mounting bracket 4 and the transverse purlin 2, it directly extends into the growth plate 71. The height of the growth plate 71 is 1.5 times the length of the fixing screw 6, so that the threads inside the fixing screw 6 and the threaded groove 72 are engaged with each other, thereby increasing the connection length of the threads of the fixing screw 6 and enhancing the stability of the connection between the fixing screw 6 and the transverse purlin 2. At least two supporting vertical plates 82 are arranged, which are symmetrically arranged at the bottom end of the supporting cross plate 81 respectively. The bottom end of the supporting cross plate 81 is fixedly welded to the top end of the supporting vertical plate 82. The vertical straight-line distance from the top end of the supporting cross plate 81 to the bottom end of the supporting vertical plate 82 corresponds to the vertical straight-line distance from the bottom end of the growth plate 71 to the bottom end of the inner wall of the transverse purlin 2, so that the top end of the supporting cross plate 81 can closely adhere to the bottom end of the growth plate 71 to play a supporting role. When installing the stabilizer 7, the auxiliary member 8 can be inserted into the transverse purlin 2 first, and then the stabilizer 7 is inserted into the transverse purlin 2. Before the fixing screw 6 is installed, under the supporting action of the auxiliary member 8, the top end of the growth plate 71 will closely adhere to the top end of the inner wall of the transverse purlin 2. After the fixing screw 6 is installed, through the supporting action of the supporting cross plate 81, it can prevent the growth plate 71 from falling due to the self-gravity of the growth plate 71 and the threaded groove 72, resulting in the situation of the connection between the growth plate 71 and the fixing screw 6 becoming loose.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
