Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a light photovoltaic frame provided with a counterweight structure. Background Art

[0002] Lightweight photovoltaic frame is a specific type of photovoltaic frame, which mainly includes aluminum alloy profile fixing frame and bracket, which is used to fix and seal solar cell modules, enhance the strength of modules, prolong service life, and facilitate transportation and installation. Lightweight photovoltaic frame is a type of frame that combines lightness, strength and cost-effectiveness. By adopting lightweight materials such as aluminum alloy and innovative design, it will greatly improve the performance and economy of photovoltaic modules. There are many kinds of light photovoltaic frames currently available on the market, but there are still some disadvantages.

[0003] The existing light photovoltaic frame is convenient for transportation and handling by setting the characteristics of light weight and thinness, but it ignores the fact that the frame is prone to tipping over in windy weather. At the same time, the general photovoltaic frame connection method is relatively cumbersome, which will greatly affect the efficiency of frame installation. Secondly, only setting a circle of frames around the solar panel will lead to problems such as unstable installation of the solar panel. For example, the Chinese utility model patent with authorization announcement number CN209562491U discloses a photovoltaic module frame, including a frame body, the frame body includes a top wall, a bottom wall and a side wall connecting the top wall and the bottom wall. The top wall, the bottom wall and the side wall form a receiving groove for accommodating the photovoltaic laminate, and the photovoltaic module frame also includes two mounting blocks arranged at the longitudinal ends of the frame body, and the mounting blocks are provided with corner code grooves opening along the longitudinal direction. The photovoltaic module frame of the utility model reduces the height of the side wall and the width of the bottom wall, and only retains the necessary corner code grooves, so that the overall weight of the photovoltaic module frame is reduced, and the entire photovoltaic module frame becomes smaller, thinner and lower in cost. However, this device facilitates the transportation and handling of the photovoltaic frame by setting the characteristics of light weight and thinness, but ignores the fact that the frame is prone to tipping over in windy weather. At the same time, the general photovoltaic frame connection method is relatively cumbersome, which will greatly affect the efficiency of frame installation. Secondly, simply setting a circle of frame around the solar panel will lead to problems such as unstable installation of the solar panel. Therefore, we propose a lightweight photovoltaic frame with a counterweight structure to solve the above problems. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] 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.

[0030] Please refer to Figures 1-6 , the present utility model provides a technical solution:

[0031] Embodiment 1: To solve the problems existing in the prior art, this embodiment adopts the following technical solution. A lightweight photovoltaic frame with a counterweight structure is provided with a cross plate 1; a counterweight mechanism is arranged below the vertical plate 4 and can add configurations of different weights at different installation positions, greatly ensuring the stability of the frame installation; a quick installation mechanism is arranged inside the protective edge sleeve 6, and the cross plate 1 and the vertical plate 4 are convenient for quick installation and disassembly, which will greatly improve the installation efficiency of the frame; a support mechanism is arranged in the middle of the cross plate 1 and can be connected below the middle of the cross plate 1 to improve the stability of the solar panel installed inside the frame. First, insert the connecting plates 2 installed on the left and right sides of a cross plate 1 into the connecting grooves 3 symmetrically opened in the front and back of the vertical plate 4, and then use the first bolt 5 to connect and fix the cross plate 1, the connecting plate 2, the connecting groove 3, and the vertical plate 4. Since a fixing block 7 is installed below the vertical plate 4, a fixing frame 8 is arranged below the fixing block 7, and the counterweight block 10 connected below the fixing frame 8 is in direct contact with the ground. The fixing block 7, the fixing frame 8, and the counterweight block 10 can provide stability for the installation of the cross plate 1 and the vertical plate 4. At the same time, a fixing groove 9 is opened below the fixing frame 8, and a convex block 12 is slidably arranged inside the fixing groove 9. The convex block 12 is fixedly connected to the first weight block 11, and at the same time, the convex block 12 is engaged with a convex groove 16. The convex groove 16 is opened inside the second weight block 13. That is, through the engagement of the convex block 12 and the convex groove 16, the first weight block 11 and the second weight block 13 can be engaged and connected together. The first weight block 11 and the second weight block 13 can be engaged and installed with the counterweight block 10, and the counterweight block 10 can be added and weighted according to the geographical location of different frame installations. Since grooves are provided inside the cross plate 1 and the vertical plate 4, after the counterweight block 10 is stable, insert the solar panel into a cross plate 1 and two vertical plates 4 that have been assembled. After the solar panel is snapped in, then connect the second cross plate 1 and the vertical plate 4. In this way, the cross plate 1 and the vertical plate 4 form a quadrilateral frame to fixedly install the solar panel in the middle. Then, loosen the second bolt 15 that fixes the cross plate 1 and the support frame 14, so that the support frame 14 rotates to a state perpendicular to the cross plate 1, and then use the second bolt 15 to fix the two support frames 14. In this way, the support frame 14 will be located below the middle of the solar panel installed inside the cross plate 1 and the vertical plate 4 to support the solar panel.

[0032] For the existing lightweight photovoltaic frame, by setting features such as light weight and thinness, it is convenient for the photovoltaic frame to be transported and carried, but it ignores the situation that the frame is prone to tipping over in strong wind weather, such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, the counterweight mechanism includes a fixed block 7 disposed below the vertical plate 4. A fixed frame 8 is fixedly arranged at the lower part inside the fixed block 7 by a second bolt 15. A counterweight block 10 is installed below the fixed frame 8. The counterweight block 10 has a certain weight and is in direct contact with the ground. That is, the settings of the fixed block 7, the fixed frame 8, and the counterweight block 10 can support the frame formed by the connection of the horizontal plate 1 and the vertical plate 4. At the same time, a fixed groove 9 is provided at the lower part inside the fixed frame 8, and a convex block 12 is arranged inside the fixed groove 9. The convex block 12 is fixedly connected to the first weight block 11, and the convex block 12 is engaged with a convex groove 16 arranged inside the second weight block 13. That is, the first weight block 11 and the second weight block 13 can be spliced together. Secondly, a clamping groove is opened at the upper part inside the counterweight block 10, so that the spliced first weight block 11 and second weight block 13 can be clamped and connected with the counterweight block 10, which can increase the weight of the counterweight block 10. The weight of the counterweight block 10 can be increased according to the geographical location where the frame is installed, which can greatly improve the stability of the support of the counterweight block 10.

[0033] Embodiment 2: For the existing frame, the connection method is relatively cumbersome, which will greatly affect the installation efficiency of the frame. As Figure 4 , Figure 5 and Figure 6 shown, the quick installation mechanism includes connecting plates 2 symmetrically arranged on the left and right sides of the horizontal plate 1. The connecting plates 2 are engaged with connection grooves 3 symmetrically opened in the front and back inside the vertical plate 4, and the horizontal plate 1, the connecting plates 2, the connection grooves 3, and the vertical plate 4 are fixedly connected by a first bolt 5. That is, the installation between the horizontal plate 1, the connecting plates 2, the connection grooves 3, and the vertical plate 4 is convenient and fast.

[0034] Embodiment 3: For the existing frame, simply setting a circle of frame around the solar panel will cause problems such as unstable installation of the solar panel. As Figure 1 , Figure 2 and Figure 6 shown, the support mechanism includes a support frame 14 rotatably arranged below the horizontal plate 1. The support frame 14 was originally in the same horizontal position as the horizontal plate 1. After the solar panel is installed inside the frame formed by the horizontal plate 1 and the vertical plate 4, the second bolt 15 fixing the horizontal plate 1 and the support frame 14 can be unscrewed to make them separated, and then the support frame 14 is rotated to make it perpendicular to the horizontal plate 1, and then the two support frames 14 are fixed by the second bolt 15. The support frame 14 is fixedly arranged below the middle part of the solar panel installed inside the frame, which will greatly enhance the stability of the installation of the solar panel.
