Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic mounting brackets, and in particular relates to a photovoltaic flexible bracket. Background Art

[0002] Photovoltaic panels are power generation devices that generate direct current when exposed to sunlight. They are composed almost entirely of thin, solid-state photovoltaic cells made of semiconductor materials (such as silicon). Flexible photovoltaic mounting systems are a new type of flexible support system used to support photovoltaic panels. They primarily utilize steel strands as the primary support structure. Straightened by diagonal cables, they resist the horizontal tension of the panel cables. High and low columns adjust the panel angle. The flexible and malleable mounting system allows for adjustment and installation based on the terrain and environment, with spans of up to 15-30 meters.

[0003] The utility model patent with domestic application number 202221676504.1 discloses a flexible photovoltaic support, including side beams, side columns, upper chords, lower chords, a support truss, an intermediate support, and diagonal braces. The side columns are bolted to the inside of the side beams, and the upper chords are connected between the side beams and the support truss via wire rope clips. The lower chords are connected between the side beams and the support truss via wire rope clips. The intermediate support is connected to the support truss via upper chords, and the diagonal braces are installed between the ground and the side beams via wire rope clips. The intermediate support includes a center beam and a center column, and the center beam and center column inside the center support are fixed by bolts. The structures on both sides of the center support are symmetrically installed via the center support. The arrangement of the side beams, side columns, upper chords, lower chords, and diagonal braces in this utility model requires little steel, has a wide range of applications, and offers high stability after installation. Although the above-mentioned utility model uses less steel, part of the supporting force is fixed to the ground by steel cables to ensure the stability of the end of the bracket. During use, the stability of the bottom is poor, and it is not convenient to adjust the height of the end according to changes in the terrain. While reducing the stability of the photovoltaic panel, it cannot be adjusted according to the terrain height. Utility Model Content

[0004] In order to solve the above technical problems, the present invention provides a photovoltaic flexible support, comprising prefabricated piles, multiple groups of columns fixedly mounted on the tops of the prefabricated piles, a main frame fixedly mounted on the tops of the columns, and multiple groups of steel cable racks fixed to the main frame. A reel is fixedly mounted on the top of the steel cable rack at one end of the column, and a limiting wheel is mounted on the top of the other steel cable rack. A steel cable is wound on the reel, and the limiting wheel assists in limiting the position of the steel cable. A photovoltaic panel is mounted on the steel cable, and the photovoltaic panel and the steel cable are fixedly mounted via a steel cable auxiliary mounting mechanism and a welding rod.

[0005] First, prefabricated piles are cast according to the photovoltaic panel laying drawings. The height and thickness of the prefabricated piles can be adjusted according to the height of the terrain at the specific installation location of the prefabricated piles and the hardness of the soil. Then the columns and main frame are installed; the steel cable is arranged through the winding wheel, and the bottom of multiple sets of limiting wheels are used for auxiliary arrangement. Finally, the photovoltaic panel is installed through the steel cable auxiliary installation mechanism.

[0006] As a further preferred technical solution of the present invention, the bottom of the precast pile is fixed to the ground via ground nails. The columns are fixed to each other via connecting plates, which have cable holes through which the steel cables are routed. A mounting plate is integrally mounted on the top of the columns.

[0007] The height and thickness of the prefabricated piles can be adjusted according to the height of the terrain at the specific installation location and the hardness of the soil to ensure the stability between the prefabricated piles and the ground, thereby ensuring the stability of the photovoltaic panel installation.

[0008] As a further preferred technical solution of the present invention, the main frame is provided with a mounting portion located at the top of each column, and the mounting portion is butt-mounted to the mounting plate via two sets of mounting bolts. The mounting portion is provided with two sets of auxiliary holes, through which the steel cables are routed. The steel cables passing through both the auxiliary holes and the cable routing holes can be positioned and locked using locking blocks.

[0009] The setting of the installation part facilitates the assembly and installation between the main frame and the column. The flexible bracket is generally installed in a large natural environment. It has a certain disassembly and assembly effect and is also convenient for transporting the flexible bracket components.

[0010] As a further preferred technical solution of the present invention; the steel cable rack is installed on the main frame at one end of the mounting part, and an auxiliary limit block is fixedly installed on one side of the steel cable rack on the main frame, a locking bolt is installed through the end of the auxiliary limit block, and a limiting rod is fixedly installed between the auxiliary limit block and the steel cable rack, and a through hole is opened on the limiting rod.

[0011] The steel rope is arranged through the winding wheel and assisted by the bottom of multiple sets of limiting wheels. After being tensioned, it is arranged on the limiting wheel at the end to the limiting rod and passes through the through hole on the limiting rod. It is then arranged in the opposite direction by the auxiliary limiting block. When passing through each set of auxiliary limiting blocks, the steel rope is locked by the locking bolt, so that the steel rope between each set of auxiliary limiting blocks is in a tensioned state. Another set of steel ropes is used to pass through the auxiliary holes, and the steel rope is arranged diagonally downward through the cable arrangement hole at the auxiliary hole position at the end. The steel rope is arranged in this way. Through this arrangement method, the steel ropes are arranged in multiple groups, which improves the support for the photovoltaic panel. The steel ropes pass through the auxiliary limiting blocks and are tensioned in sequence to ensure that the steel ropes are taut, thereby preventing them from being exposed to the sun and rain for a long time and affecting their elasticity. At the same time, they can be inspected in sections during the later maintenance process.

[0012] As a further preferred technical solution of the present invention, the steel cable auxiliary installation mechanism is arranged in six groups and installed on the steel cable rope, and the welding rods have different lengths depending on the position of the penetration block. The steel cable auxiliary installation mechanism includes a penetration block that penetrates the steel cable rope, a bottom locking block that is clamped and installed at the bottom of the penetration block, and a flip block fixedly installed at the top of the penetration block.

[0013] The auxiliary cable mounting mechanisms are installed in pairs through the steel cables arranged by the reel, and another pair through another pair through another pair of cables arranged inside the auxiliary hole. The bottom of the photovoltaic panel is fixed to the welding rod to ensure the tilt angle of the photovoltaic panel, thereby ensuring the power generation of the photovoltaic panel arrangement. The final pair of auxiliary cable mounting mechanisms is installed through the steel cables arranged inside the cable arrangement hole, and the welding rod at the top of the cable supports the photovoltaic panel from the wind.

[0014] As a further preferred technical solution of the present invention; the welding rod is flipped and connected to the through block through the flip block, and the through block and the bottom locking block are respectively provided with mounting holes and extrusion holes, and the bottom locking block and the through block are fixed and locked by fixing bolts.

[0015] The steel cables passing through the auxiliary holes and the cable holes are arranged in the same group, so the bottom of the photovoltaic panel and the supporting structure are subjected to the same force, while the steel cables arranged by the winding wheel only support the top of the photovoltaic panel, so that the support force on the top of the photovoltaic panel is greater. The top of the photovoltaic panel is generally high and is most affected by wind. While ensuring the stability of the photovoltaic panel, the support effect on the top is increased to ensure the stability of the flexible bracket in supporting the photovoltaic panel. Beneficial effects

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The steel rope is arranged through the winding wheel and assisted by the bottom of multiple sets of limiting wheels. After being tensioned, it is arranged on the limiting wheel at the end to the limiting rod and passes through the through hole on the limiting rod. It is then arranged in the opposite direction by the auxiliary limiting block. When passing through each set of auxiliary limiting blocks, the steel rope is locked by the locking bolt, so that the steel rope between each set of auxiliary limiting blocks is in a tensioned state. Another set of steel ropes is used to pass through the auxiliary holes, and the steel rope is arranged diagonally downward through the cable arrangement hole at the auxiliary hole position at the end. The steel rope is arranged in this way. Through this arrangement method, the steel ropes are arranged in multiple groups, which improves the support for the photovoltaic panel. The steel ropes pass through the auxiliary limiting blocks and are tensioned in sequence to ensure that the steel ropes are taut, thereby preventing them from being exposed to the sun and rain for a long time and affecting their elasticity. At the same time, they can be inspected in sections during the later maintenance process.

[0018] The steel cables passing through the auxiliary holes and the cable holes are arranged in the same group, so the bottom of the photovoltaic panel and the supporting structure are subjected to the same force, while the steel cables arranged by the winding wheel only support the top of the photovoltaic panel, so that the support force on the top of the photovoltaic panel is greater. The top of the photovoltaic panel is generally high and is most affected by wind. While ensuring the stability of the photovoltaic panel, the support effect on the top is increased to ensure the stability of the flexible bracket in supporting the photovoltaic panel.
