Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic brackets, and in particular to a photovoltaic bracket made of polyurethane fiberglass. Background Art

[0002] At present, photovoltaic power generation technology has been widely used. As a key supporting structure, the performance of photovoltaic brackets is directly related to the stability and life of the entire system. Especially in coastal areas, photovoltaic brackets must not only withstand the influence of severe weather such as high temperature and high humidity, but also have strong corrosion resistance and structural stability, which directly affects the reliability and economy of the entire photovoltaic power generation system. Therefore, the selection and design of photovoltaic brackets have gradually become an important part of improving the overall performance of photovoltaic power generation systems, which has also promoted the continuous progress and development of technology in this field.

[0003] In order to improve the corrosion resistance of photovoltaic brackets, the traditional method mainly uses steel or aluminum alloy as the main material. Among them, steel is widely used due to its high strength and good machinability, but in terms of corrosion protection, it is usually necessary to add anti-corrosion coatings or choose higher quality metal materials to extend its service life. Anti-corrosion coating technology improves the corrosion resistance of steel brackets by coating materials such as epoxy resin or polyurethane on the surface of steel brackets; while high-quality metal materials such as stainless steel or high-strength aluminum alloys have better corrosion resistance, but their cost is higher. In addition, there are also solutions that use composite materials to take into account both corrosion resistance and economy, such as carbon fiber reinforced plastics and glass fiber reinforced plastics.

[0004] However, the above methods all have different limitations in practical applications. For the anti-corrosion coating on the surface of steel, although it can resist the erosion of salt spray and humid environment to a certain extent, it may peel off or be damaged after long-term use. Although the use of high-quality metal materials can effectively improve the corrosion resistance, it is difficult to popularize it in large-scale projects due to the high cost. When installed at the seaside or other areas with severe salt spray, photovoltaic brackets must also face the possible invasion of seawater. Even if the material has excellent corrosion resistance, long-term immersion in seawater may cause damage to the photovoltaic panel function and increase the risk of internal structure damage. Summary of the invention

[0005] In order to improve the anti-corrosion performance of a photovoltaic bracket and reduce the possibility of the photovoltaic panel being immersed in seawater, the present invention provides a photovoltaic bracket made of polyurethane glass fiber material.

[0007] By adopting the above technical solution, the photovoltaic bracket is supported by the support assembly and the base. The support assembly is made of polyurethane fiberglass material. The polyurethane fiberglass material is not susceptible to chemical corrosion and is suitable for various environments, which improves the corrosion resistance of the photovoltaic bracket. At the same time, the need for frequent replacement of brackets is reduced, reducing maintenance costs. The support rod slides with the pillar, and the support rod, mounting plate and photovoltaic panel move up with the rise of sea water under the action of the floating plate, thereby reducing the risk of damage to the photovoltaic panel function. The reinforcement device connects the pillar and the mounting plate to ensure structural stability and limit the distance between the mounting plate and the pillar, thereby improving the overall stability of the photovoltaic bracket. When the sea water drops, the support rod moves downward, which can reduce the distance between the photovoltaic panel and the ground, thereby improving the stability of the photovoltaic bracket.

[0009] By adopting the above technical solution, the reinforcement device enhances the overall stability of the photovoltaic bracket through the first reinforcement component and the second reinforcement component, wherein when the photovoltaic panel rises, the sliding connection of the first slider in the first slide groove causes the first rod to rotate toward the vertical direction, and the first rod can lengthen the length of the reinforcement rod, ensuring that the mounting plate can move smoothly when the sea water rises, thereby effectively reducing the risk of damage to the photovoltaic panel.

When the support rod stops moving, the synchronization component and the limit component both stop moving, thereby ensuring that the photovoltaic panel moves up stably, reducing the possibility of damage to the photovoltaic panel function, and ensuring the stability of the overall structure.

[0034] The photovoltaic bracket is supported by the support assembly 2 and the base 1. The support assembly 2 is made of polyurethane glass fiber material. The polyurethane glass fiber material is not susceptible to chemical corrosion and is suitable for various environments, which improves the anti-corrosion performance of the photovoltaic bracket.

The reinforcement device connects the pillar 21 and the mounting plate 23 to ensure structural stability and limit the distance between the mounting plate 23 and the pillar 21, thereby improving the overall stability of the photovoltaic bracket. When the sea water drops, the support rod 22 moves downward, which can reduce the distance between the photovoltaic panel 3 and the ground, thereby improving the stability of the photovoltaic bracket.

A plurality of reinforcing ropes 11 are arranged, and the plurality of reinforcing ropes 11 are evenly distributed around the outer wall of the pillar 21.

[0036] The reinforcement rope 11 enhances the overall structural stability of the photovoltaic bracket, reduces the possibility of tipping over or shifting under strong winds or wave impacts, and improves the reliability of the photovoltaic bracket in harsh environments.

The reinforcement rod 51 passes through the through holes 41.

[0041] The through hole 41 opened on the floating board 4 can ensure the smoothness of the reinforcement rod 51 when it moves up and down with the support rod 22, reducing the possibility of interference between the reinforcement rod 51 and the floating board 4 during movement, thereby ensuring the overall stability of the photovoltaic bracket and the normal movement of the photovoltaic panel 3 with the rise and fall of sea water, reducing the possibility of damage to the function of the photovoltaic panel 3.

[0044] When the photovoltaic panel 3 rises, the first slider 521 is slidably connected in the first slide groove 231, and the second slider 531 is slidably connected in the second slide groove 232, so that the first rod 52 and the second rod 53 are both rotated toward the vertical direction. The first rod 52 and the second rod 53 can lengthen the length of the reinforcement rod 51 and evenly disperse the stress, ensuring that the mounting plate 23 can move smoothly when the sea water rises, thereby effectively reducing the risk of damage to the photovoltaic panel 3.

[0045] Reference Figure 2 The first slide groove 231 and the second slide groove 232 are arranged one by one, and the first slide groove 231 and the second slide groove 232 in the same group are located on the same vertical plane, and the length direction of the first slide groove 231 and the length direction of the second slide groove 232 are both perpendicular to the first direction x.

[0047] The first slider 521 and the second slider 531 are both in sliding contact with the mounting plate 23 via the ball bearing 7, which effectively reduces the friction between the first slider 521 and the second slider 531 and the mounting plate 23, so that the reinforcement component can more smoothly adjust the angle of the photovoltaic bracket when the sea water rises and falls, thereby further improving the overall stability of the photovoltaic bracket and the protective effect of the photovoltaic panel 3.

[0048] Reference Figure 3 and Figure 4 The mounting plate 23 is connected to a limiting device, and the limiting device includes a limiting assembly 8 and a synchronization assembly 9. The limiting assembly 8 is provided with at least one group. In this embodiment, the limiting assembly 8 is provided with two groups, and the two groups of limiting assemblies 8 are symmetrically arranged and correspond to the first slider 521 and the second slider 531 one by one. Both groups of limiting assemblies 8 are connected to the synchronization assembly 9.

[0049] Reference Figure 3 and Figure 4 The two sets of limiting components 8 have the same structure. Therefore, this embodiment only describes in detail the limiting component 8 connected to the first slider 521.

The screw rod 81 is arranged horizontally, and both ends of the screw rod 81 are rotatably connected with a protrusion, and the protrusion is fixedly connected to the mounting plate 23. The screw rod 81 is located between the two first slide grooves 231. The moving block 82 is sleeved on the screw rod 81 and is threadedly connected to the screw rod 81. The moving block 82 is slidably abutted against the mounting plate 23.

[0051] Reference Figure 2 and Figure 3 , the first connecting rod 83 and the second connecting rod 84 are respectively arranged on both sides of the moving block 82. The first connecting rod 83 is arranged corresponding to the first reinforcement component 5, one end of the first connecting rod 83 is fixedly connected to the moving block 82, and the other end is fixedly connected to the first slider 521 of the first reinforcement component 5.

The synchronization component 9 is connected to the screw rod 81.

[0052] When the support rod 22 moves upward with the rise of sea water, the synchronization component 9 can drive the screw 81 to rotate. The rotation of the screw 81 causes the moving block 82 to move axially along the screw 81, and then drives the first sliding blocks 521 connected to each other to slide in the first sliding groove 231 through the first connecting rod 83 and the second connecting rod 84 respectively. The two first sliding blocks 521 move synchronously, thereby realizing the limitation of the first sliding block 521, and then realizing the movement limitation of the first rod 52, so that the first rod 52 cooperates with the reinforcement rod 51 to support the mounting plate 23.

[0056] Reference Figure 4 The second pulley 95 is disposed between the two screw rods 81 , and both screw rods 81 are fixedly connected to the shaft of the second pulley 95 .

[0057] When the sea water rises, the support rod 22 moves up with the sea water, driving the gear 92 to move upward along the movable groove 212, and the rack 91 keeps its position unchanged, thereby causing the gear 92 to rotate. The gear 92 drives the first pulley 94 to rotate through the rotating shaft 93; the first pulley 94 drives the second pulley 95 to rotate through the synchronous belt 96, and the second pulley 95 drives the two screws 81 to rotate synchronously.

The support assembly 2 and the reinforcement device are made of polyurethane glass fiber material, which is not easily corroded by chemicals and is suitable for various environments, thus improving the anti-corrosion performance of the photovoltaic bracket. At the same time, the need for frequent replacement of the bracket is reduced, and the maintenance cost is reduced.

[0059] When the seawater rises, the floating board 4 will drive the support rod 22, the mounting plate 23 and the photovoltaic panel 3 to move upward with the rising seawater, thereby reducing the risk of damage to the photovoltaic panel 3. The upward movement of the support rod 22 will drive the gear 92 to move upward along the movable groove 212, and the rack 91 will keep its position unchanged to rotate the gear 92. The gear 92 drives the first pulley 94 to rotate through the rotating shaft 93, and the first pulley 94 drives the second pulley 95 to rotate through the synchronous belt 96, and the second pulley 95 drives the two screws 81 to rotate synchronously.

[0060] The rotation of each screw rod 81 will drive the moving block 82 connected to it to move, and the moving block 82 moves away from the first slide groove 231 and the second slide groove 232. The moving block 82 drives the first connecting rod 83 and the second connecting rod 84 connected to it to move, and the first connecting rod 83 drives the first slide groove 231 to move along the first slide groove 231, and the second connecting rod 84 drives the second slider 531 to move along the second slide groove 232, and makes the first slider 521 and the second slider 531 approach each other, and the first slider 521 and the second slider 531 drive the first rod 52 and the second rod 53 away from one end of the reinforcement rod 51 to approach each other, and the first rod 52 and the second rod 53 can increase the length of the reinforcement rod 51, and the first rod 52 and the second rod 53 evenly disperse the stress, so that the mounting plate 23 can move smoothly when the sea water rises, thereby effectively reducing the risk of damage to the photovoltaic panel 3.
