Description

Technical Field

[0001] This utility model belongs to the technical field of PHC high-pile photovoltaic support in high wind pressure areas, and particularly relates to a device for improving the wind suction resistance of PHC high-pile photovoltaic support in high wind pressure areas. Background Technology

[0002] Solar energy, as a renewable energy source, holds an irreplaceable position in long-term energy strategy development. Photovoltaic power generation is a technology that uses photovoltaic panels to collect solar energy and generate electricity. Photovoltaic support structures are generally made of carbon steel and are used to install and fix photovoltaic modules to achieve solar power generation. Conventional PHC high-pile photovoltaic support structures rely on PHC pile clamps to bear the wind suction force. In areas with high wind pressure, under repeated strong wind suction, the PHC pile clamps may experience significant upward displacement due to the strong wind suction, causing local deformation or even complete upward movement of the photovoltaic support structure, causing it to slide off the top of the PHC pile and resulting in damage to the entire photovoltaic support structure and system. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a device for improving the wind resistance of PHC high-pile photovoltaic support in high wind pressure areas that has a reasonable structure and is stable and reliable.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] The PHC high-pile photovoltaic support device for high wind pressure areas is mainly composed of a steel plate at the top of the pile, a crossarm, and a steel wire rope. The steel plate at the top of the pile has anchor bolt holes, and the crossarm has steel wire rope holes. The crossarm is placed horizontally on the steel plate at the top of the pile, and the steel wire rope passes through the steel wire rope hole in the middle, with both ends connected to the anchor bolt holes by bolts.

[0006] The steel plate at the top of the pile is pre-embedded on the top of the PHC high pile and becomes an integral part of the PHC high pile.

[0007] The crossbeam is placed horizontally on the steel plate at the top of the pile and its two ends are bolted to the columns of the photovoltaic support on both sides of the PHC high pile.

[0008] The wire rope has built-in fixing bolts at both ends.

[0009] The wire rope is composed of two half wire ropes connected by a wire rope tensioner. One end of each half wire rope is a fixing bolt and the other end is a turnbuckle. The turnbuckles of the two half wire ropes are connected by the wire rope tensioner.

[0010] The steel plate at the top of the pile is a circular steel plate with anchor bolt holes evenly distributed along the circumference. The two ends of the wire rope are connected to the anchor bolt holes on the circular steel plate by their own fixing bolts.

[0011] The crossarm is made of rolled equilateral angle steel, and a wire rope hole is set in the middle of the crossarm.

[0012] One leg of the angle steel is parallel and attached to the steel plate at the top of the pile, while the other leg is perpendicular to the steel plate at the top of the pile (horizontal plane).

[0013] To address the problems existing with PHC high-pile photovoltaic (PV) supports in high-wind-pressure areas, the inventors designed a device to enhance the wind suction resistance of PHC high-pile PV supports in such areas. The device mainly consists of a steel plate at the top of the pile, a crossarm, and steel wire ropes. Anchor bolt holes are provided on the steel plate at the top of the pile, and steel wire rope holes are provided on the crossarm. The crossarm is placed horizontally on the steel plate at the top of the pile, and the steel wire rope passes through the middle hole, with both ends bolted to the anchor bolt holes. After applying this invention, the PV support and the PHC high pile form a unified whole to resist strong wind suction. In high-wind-pressure areas where strong winds are frequent, this enhances the wind suction resistance of the PV support, overcoming the problem that strong winds may cause the entire PV support to slide upwards, resulting in local deformation or even, due to excessive upward displacement, the entire PV support sliding off the top of the PHC pile, causing damage to the PV support and its system.

[0019] like Figure 1 Character Figure 4 As shown, the wind-resistant device for improving the wind suction capacity of PHC high-pile photovoltaic supports in high wind-pressure areas, as described in this utility model, mainly consists of a steel plate 1 at the top of the pile, a crossbeam 2, and a steel wire rope 3. Among them,

[0020] The steel plate at the top of the pile is pre-embedded on the top of the PHC high pile and is integrated with the PHC high pile 6. The steel plate at the top of the pile is a circular steel plate with anchor bolt holes evenly distributed along the circumference of the circular steel plate to ensure a firm connection with the wire rope bolts.

[0021] The crossarm is made of rolled equilateral angle steel, with a wire rope hole 9 in the middle for the wire rope to pass through. The crossarm is placed horizontally on the steel plate at the top of the pile, with one leg of the angle steel parallel to and attached to the steel plate at the top of the pile, and the other leg perpendicular to the steel plate at the top of the pile (horizontal plane); both ends of the crossarm are bolted to the columns of the photovoltaic support on both sides of the PHC high pile.

[0022] The wire rope consists of two half-wire ropes connected by a wire rope tensioner 4. Each half-wire rope has a fixing bolt at one end and a turnbuckle at the other end. One half-wire rope passes through the wire rope hole on the crossarm and is then connected to the turnbuckle of the other half-wire rope via the wire rope tensioner to form a single unit. Finally, both ends of the wire rope are connected to the anchor bolt holes on the circular steel plate via their built-in fixing bolts.

[0023] The photovoltaic support is fixed to the PHC high pile by the column 5 and the clamp. This utility model uses the crossbeam to stabilize the column, and further uses the steel wire rope to stabilize the crossbeam to the steel plate at the top of the pile that is embedded in the top of the PHC high pile and is integrated with the PHC high pile. This improves the photovoltaic support's wind resistance and solves the problem of the photovoltaic support deforming, shifting, or sliding off the PHC pile due to strong winds, which would damage the entire system.
