Description

Technical Field

[0001] This utility model relates to the field of wind-pressure resistant photovoltaic support technology, and more specifically, to a wind-pressure resistant photovoltaic support. Background Technology

[0002] With industrial development, new energy sources are receiving increasing attention, and the utilization of solar energy is becoming more and more widespread. Photovoltaic (PV) brackets are special supports designed for placing, installing, and fixing photovoltaic (PV) panels in a photovoltaic power generation system. Currently, PV panels require brackets for support and fixation during installation. The wind pressure resistance of PV panels depends on the stability of their installation. Currently, there are instances where insufficient bracket stability leads to PV panel collapse, making it impossible to guarantee the stability of the PV brackets.

[0003] Announcement No. CN219372321U proposes a wind-pressure resistant photovoltaic support that is easy to install. This device can limit the position of the photovoltaic panel, is highly flexible and provides stable support, and is wind-pressure resistant while being easy to install. However, in windy environments, the surface of the photovoltaic panel is easily subjected to impacts from gravel or other hard impurities, so the protection effect of the photovoltaic panel in the comparison document needs to be improved.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0033] like Figures 1 to 3 As shown, a wind-resistant photovoltaic support includes a cement block 1 (the cement block 1 weighs approximately 300 catties and is cast in place, thereby improving the stability of the photovoltaic support in high wind conditions), a base plate 2, a photovoltaic panel placement frame 3, a support plate 4, a positioning component, a limiting frame 5, a high-strength screw 6, a wind-resistant protective alloy mesh frame 7, an installation rod 8, and a nut 9.

[0034] The base plate 2 is fixed on the cement block 1, which is cast integrally with the ground.

[0035] The photovoltaic panel placement rack 3 is welded at an angle onto the base plate 2;

[0036] The tray 4 is welded perpendicularly to the photovoltaic panel placement rack 3;

[0037] The positioning component is set on the photovoltaic panel placement rack 3, and the positioning component cooperates with the tray 4;

[0038] The limiting frame 5 is welded onto the base plate 2;

[0039] Several high-strength screws 6 are welded onto the base plate 2 and are located outside the limiting frame 5;

[0040] The outer wall of the wind-resistant protective alloy mesh frame 7 is circumferentially fitted with the inner wall of the limiting frame 5;

[0041] The mounting rod 8 is welded to the outside of the wind-resistant protective alloy mesh frame 7 and corresponds one-to-one with the high-strength screw rod 6. The mounting rod 8 is provided with a through hole that allows the high-strength screw rod 6 to pass through.

[0042] Nut 9 is threaded into high-strength screw 6.

[0043] Specific implementation of the embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the positioning assembly includes a fixing plate 10, a long screw 11, a knob 12, a positioning plate 13, a guide roller 14, and an anti-loosening bolt 15.

[0044] The fixing plate 10 is vertically welded to the photovoltaic panel placement frame 3;

[0045] The long screw 11 is threadedly connected to the fixing plate 10, and one end of the long screw 11 is connected to the knob 12. The other end of the long screw 11 is rotatably connected to the positioning plates 13 that are parallel to and spaced apart on the upper surface of the photovoltaic panel placement rack 3.

[0046] The guide roller 14 is welded to the positioning plate 13, and the guide roller 14 is slidably fitted with the fixing plate 10;

[0047] The anti-loosening bolt 15 is installed on the fixing plate 10 and cooperates with the long screw 11;

[0048] To further obstruct and limit the movement of the photovoltaic panel on both sides, the above-described embodiment is further optimized, such as... Figure 3 As shown, the main body of the positioning plate 13 is U-shaped and a rubber pad 16 is provided on the inner side of the positioning plate 13.

[0049] To reduce the probability of water accumulation at point 4 of the tray, the above-described embodiment is further optimized, such as... Figure 1 As shown, the tray 4 has several drainage holes 17.

[0050] In a further refinement of the embodiment of this utility model, the mesh of the wind-resistant protective alloy mesh frame 7 adopts a gradually changing layout with denser mesh at the top and sparser mesh at the bottom, and the wind-resistant protective alloy mesh frame 7 is made of zinc-aluminum-magnesium alloy mesh frame to have good corrosion resistance.

[0051] Further optimization of the above embodiment involves providing several reinforcing ribs on the inner side of the wind-resistant protective alloy mesh frame 7, with the reinforcing ribs and mesh holes spaced apart. Specifically, a gradient mesh layout with denser holes at the top and sparser holes at the bottom (15mm upper hole diameter / 30mm lower hole diameter) is adopted. The Bernoulli effect is used to generate rising airflow to offset part of the wind pressure. At the same time, the reinforcing ribs extend the service life of the wind-resistant protective alloy mesh frame 7 and effectively disperse wind pressure stress, thereby improving the wind pressure resistance of the photovoltaic support and protecting the surface of the photovoltaic panel.

[0052] The working process of this utility model is as follows:

[0053] First, the photovoltaic panel is placed at an angle on the photovoltaic panel placement rack 3, so that the bottom of the photovoltaic panel contacts the support plate 4. Then, the knob 12 is turned to drive the positioning plate 13 to move down in a direction parallel to the upper surface of the photovoltaic panel placement rack 3 and then contact the top of the photovoltaic panel. This will limit the photovoltaic panel. At the same time, the two sides of the positioning plate 13 are on the outside of the photovoltaic panel, thus preventing the photovoltaic panel from falling off the photovoltaic panel placement rack 3 from the sides. After the photovoltaic panel is firmly limited, the anti-loosening bolt 15 is installed to limit the position of the long screw 11. This can reduce the probability of the long screw 11 rotating in windy weather.

[0054] Before strong winds occur, the wind-resistant protective alloy mesh frame 7 is pre-installed on the base plate 2. The specific process is as follows: first, the outer wall of the wind-resistant protective alloy mesh frame 7 is circumferentially fitted with the inner wall of the limiting frame 5 (at this time, the installation area of ​​the wind-resistant protective alloy mesh frame 7 is accurately defined). At this time, several high-strength screws 6 can pass through the through holes, and then multiple nuts 9 are used to complete the multiple positional constraints between the wind-resistant protective alloy mesh frame 7 and the base plate 2. In this way, during subsequent strong winds, the presence of the wind-resistant protective alloy mesh frame 7 can intercept flying debris, preventing branches, gravel, and other materials in the wind from directly impacting the surface of the photovoltaic panel and causing damage. At the same time, the mesh structure of the wind-resistant protective alloy mesh frame 7 can cut the airflow to form micro vortices, dispersing concentrated wind pressure into multi-directional forces, reducing the peak value of single-point stress on the support, and improving the overall bending stiffness through multi-point bolt connections during installation.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
