Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic brackets, and in particular relates to a photovoltaic flexible bracket system using a fixed bracket foundation as a side anchor pile. Background Art

[0002] Photovoltaic flexible support systems are often used in photovoltaic projects for complementary fishing and photovoltaic projects on offshore beaches in soft soil areas. Photovoltaic flexible support systems have the advantages of large span, high clearance, low cost, and environmental friendliness. They can better integrate photovoltaics with fisheries, photovoltaics with agriculture, photovoltaics with aquaculture, photovoltaics with forestry, and photovoltaics with sand control. When using photovoltaic flexible supports in soft soil areas, it is necessary to set up side anchor piles to bear the horizontal lateral load and upward pull force of the upper cable. Because the horizontal bearing capacity of the pile body in soft soil areas is relatively small, the side anchor piles need to have a larger diameter and a longer depth in the soil. This causes huge economic waste.

[0003] The existing flexible photovoltaic bracket side anchor pile solutions mainly include pile foundation solutions and inclined pile solutions. The pile foundation solution should determine the pile diameter, pile length and depth of burial in the ground according to site conditions, geological conditions, pile top load and "Technical Specifications for Building Pile Foundations" and "Technical Specifications for Solar Power Station Bracket Foundations". However, the pile diameter is usually larger, the pile length is longer, the burial depth is deeper, and the cost is higher. The inclined pile solution is to keep the inclined pile at the same angle as the inclined tie rod, and use the pile foundation pull-out resistance to meet the tie rod force. In addition, the pile foundation of this solution is not affected by horizontal forces. In theory, the pile type can be reduced and the project cost can be reduced. However, the inclined pile construction needs to maintain the same axial direction as the inclined tie rod, and the inclined pile construction is difficult. There is no special equipment for the time being. During construction, the line may break and the pile may not sink.

[0004] The existing flexible photovoltaic support side anchor piles are rammed into the ground and are only used for the flexible photovoltaic support inclined cable or inclined rod anchoring. They have a single function and a large pile diameter, making on-site construction difficult and costly. The space resources above the anchor piles are wasted, and the power generation efficiency cannot be maximized. The current photovoltaic fixed support system and photovoltaic flexible support system are used independently, that is, a fixed support system is used independently in a certain area, and a flexible photovoltaic support system is used independently in another area.

[0005] In view of this, the inventor hopes to design a photovoltaic flexible support system that uses a fixed support foundation as a side anchor pile. Summary of the invention

[0006] The purpose of the present invention is to overcome the above-mentioned problems existing in the conventional technology and to provide a photovoltaic flexible support system which utilizes a fixed support foundation as a side anchor pile.

[0007] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

There are two cables and each of them is an annular structure. The suspension box is used to drive the cables to perform cyclic displacement. A rod is fixed on the back side of the support photovoltaic panel, and two suspension cable connectors for connecting to the corresponding cables are installed on the rod.

[0015] Furthermore, in the above-mentioned photovoltaic flexible support system using the fixed support foundation as the side anchor pile, the center angle corresponding to the opening of the arc-shaped limit cover and the arc-shaped baffle is 160-165°.

[0016] Furthermore, in the above-mentioned photovoltaic flexible support system that uses a fixed support foundation as a side anchor pile, the mounting block is provided with a toggle groove that facilitates the rotation of the arc-shaped baffle, the position of the toggle groove is staggered with the convex tube, and the toggle groove is connected to the arc-shaped slide groove.

[0017] Furthermore, in the above-mentioned photovoltaic flexible support system using the fixed support foundation as the side anchor pile, the cross-section of the arc-shaped slide groove is a T-shaped structure that is wide inside and narrow outside.

[0018] The beneficial effects of the present invention are:

[0019] The structural design of the present invention is reasonable. It uses the fixed bracket assembly and the flexible bracket assembly together, and sets the fixed bracket assembly at the end of the flexible bracket assembly to form a photovoltaic fixed bracket matrix.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In this embodiment, the fixed support assembly 1 includes a fixed support anchor pile (not shown in the figure), a fixed support photovoltaic panel 11, a side anchor pile 12, an anti-wind cable 13 and a rigid support 14. The upper end of the fixed support anchor pile is installed with the fixed support photovoltaic panel 11. The side anchor pile 12 is connected to the fixed support anchor pile through the anti-wind cable 13. The rigid support 14 is commonly installed between the fixed support anchor piles in the same row, and the rigid support 14 is located at the end protruding away from the side anchor pile 12, and the protruding part serves as the installation base of the flexible support assembly 2.

[0034] In this embodiment, the fixing support anchor piles in the fixing support assemblies 1 in different rows are connected by a rigid cross beam.

There are two suspension cables 22 and each of them is an annular structure as a whole. The suspension box 21 is used to drive the suspension cables 22 to perform cyclic displacement. A rod 24 is fixed on the back side of the support photovoltaic panel 23, and two suspension cable connectors 25 for connecting to the corresponding suspension cables 22 are installed on the rod 24.

[0037] In this embodiment, the cable box 21 is provided with a cable channel for the two cables 22 to circulate therethrough. The cable box 21 is provided with a driving roller pair 211 for driving the cables 22 to circulate and a steering roller 212 for steering the cables 22 .

[0038] In this embodiment, the cable connector 25 includes a mounting block 251, in which an arc-shaped limit cover 252 is provided, and an arc-shaped slide groove is provided inside the arc-shaped limit cover 252 for slidably limiting the arc-shaped baffle 253.
