Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic support technology, specifically a counterweight anti-wind vibration fixed photovoltaic support. Background Technology

[0002] Conventional photovoltaic mounting systems, such as Figure 1 As shown, this is an all-steel structure system composed of main components such as front column 1, rear column 2, front diagonal brace 3, rear diagonal brace 4, diagonal beam 5, and purlin 6. The entire steel structure is lightweight. Under wind load, the photovoltaic support system has poor structural stiffness and a long natural vibration period, resulting in wind-induced vibration. This is particularly problematic for photovoltaic projects located in high-wind-speed areas or mountainous regions with complex terrain. Because the photovoltaic support system is primarily affected by wind loads, its poor structural stiffness makes it prone to node or member failure under wind-induced vibration, potentially leading to photovoltaic panel failure or structural instability and collapse. Utility Model Content

[0003] The purpose of this invention is to provide a counterweight anti-wind vibration fixed photovoltaic support to reduce the wind vibration of the photovoltaic support.

[0004] The technical solution adopted by this utility model is: a counterweight anti-wind vibration fixed photovoltaic bracket, including a front column and a rear column. A front counterweight is fitted on the front column. The front counterweight is movably fitted with the front column along the axial direction of the front column. A front clamp is provided on the front column. The front counterweight is located on the front clamp and the front clamp limits the position of the front counterweight.

[0005] A rear counterweight is also fitted on the rear column. The rear counterweight is movably fitted with the front column along the axial direction of the front column. A rear clamp is provided on the front column. The rear counterweight is located on the rear clamp and is limited by the rear clamp.

[0006] Furthermore, the front clamp is adjustable in height and fixed to the front column; the rear clamp is adjustable in height and fixed to the rear column.

[0007] Furthermore, the front clamp and the rear clamp adopt the same structure, both including two clamping plates arranged opposite each other. Each clamping plate includes an arc-shaped circumferential section and connecting sections located on both sides of the circumferential section. The circumferential sections of the two clamping plates form a ring around the outer periphery of the corresponding column, and the connecting sections are tightened by clamping bolt assembly.

[0008] Furthermore, both the front counterweight and the rear counterweight are precast concrete blocks made using the same standard components.

[0009] Furthermore, the front counterweight and the rear counterweight are in an integral ring shape.

[0010] Furthermore, the counterweight is a ring formed by splicing together two identical unit blocks.

[0011] The present invention has the following beneficial effects: by setting counterweights on the front and rear columns, the present invention significantly improves the overall mass of the support, reduces the wind vibration coefficient, and enhances the overall stability of the structure.

[0012] The height of the counterweight along the column can be adjusted by means of the clamps, allowing for flexible adjustment of the counterweight's position according to the actual wind load distribution and frost depth, thus optimizing the wind and frost resistance effect.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0024] like Figure 1 As shown, a conventional photovoltaic (PV) support system is an all-steel system composed of main components such as a front column 1, a rear column 2, a front diagonal brace 3, a rear diagonal brace 4, a diagonal beam 5, and purlins 6. The front column 1 is shorter than the rear column 2. The diagonal beam 5 is mounted on the tops of the front column 1 and the rear column 2 via supports. One end of the front diagonal brace 3 is connected to the bottom of the front column 1, and the other end is connected to the middle of the diagonal beam 5; one end of the rear diagonal brace 4 is connected to the bottom of the rear column 2, and the other end is connected to the middle of the diagonal beam 5.

[0025] The counterweight anti-wind vibration fixed photovoltaic support disclosed in this utility model is an improvement on the above-mentioned conventional photovoltaic support. The improvement is as follows: Figure 2 As shown, a front counterweight 7 is fitted onto the front column 1. The front counterweight 7 is movably fitted with the front column 1 along its axial direction. A front clamp 8 is provided on the front column 1, and the front counterweight 7 rests on the front clamp 8, which limits its position. Specifically, the front counterweight 7 has a through hole in its center, and the front column 1 is inserted into this hole. This counterweight installation method requires no structural modifications to the original structure of the front column 1, such as drilling. The front clamp 8 provides support for the front counterweight 7. Similarly, a rear counterweight 9 is fitted onto the rear column 2. The rear counterweight 9 is movably fitted with the front column 1 along its axial direction. A rear clamp 10 is provided on the front column 1, and the rear counterweight 9 rests on the rear clamp 10, which limits its position.

[0026] This invention significantly improves the overall mass of the support frame, reduces the wind vibration coefficient, and enhances the overall stability of the structure by setting counterweights on the front column 1 and the rear column 2.

[0027] The front clamp 8 is adjustablely fixed to the front column 1 at a height that is also adjustable along the front column 1 at a height that is also adjustable along the rear column 2. This configuration allows for flexible adjustment of the counterweight's height position according to the actual wind load distribution and frost depth, thus optimizing wind and frost resistance.

[0028] Specifically, such as Figure 3 and Figure 4As shown, the front clamp 8 and the rear clamp 10 adopt the same structure, both including two opposing clamping plates 11. Each clamping plate 11 includes an arc-shaped encircling section 11-1 and connecting sections 11-2 located on both sides of the encircling section 11-1. The encircling sections 11-1 of the two clamping plates 11 form a ring around the outer periphery of the corresponding column, and the connecting sections 11-2 are tightened by a clamping bolt assembly 12. The clamping structure disclosed in this embodiment tightly encircles the column by tensioning two identical clamping plates through a bolt assembly, ensuring reliable connection and facilitating disassembly and subsequent maintenance.

[0029] Preferably, both the front counterweight 7 and the rear counterweight 9 are precast concrete blocks made from the same standard components. Standardized production of the counterweights results in high production efficiency and ease of use. The number of counterweights can be easily increased or decreased according to calculation requirements to meet the weighting needs.

[0030] like Figure 5 and Figure 6 As shown, the front counterweight 7 and the rear counterweight 9 are in an integral ring shape and are fitted onto the outer periphery of the corresponding column. This installation structure is stable and does not affect the original support structure.

[0031] Of course, the counterweight can also be as follows: Figure 7 As shown, the counterweight is a ring formed by splicing two identical unit blocks. The two identical unit blocks are opposite each other and connected together by a connecting bolt assembly. This allows the existing support structure to be installed first, followed by the installation of the counterweight, facilitating the modification of existing photovoltaic supports. When installing this type of split counterweight, first loosen the connecting bolt assembly, wrap the two unit blocks around the column from both sides, and then install the connecting bolt assembly to fix the two unit blocks together, tightly gripping the column. In this manual, the counterweight refers to the front counterweight 7 and the rear counterweight 9 collectively. The column refers to the front column 1 and the rear column 2 collectively.

[0032] It should be noted that whether it is a whole ring or a ring made up of pieces, it is a ring in a broad sense, that is, a closed part with a hole in the middle, such as a circular ring, a part with an inner circle and an outer square, etc.

[0033] Although the present invention has been described herein with reference to embodiments thereof, the above embodiments are merely general implementations of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
