Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic technology, specifically relating to a photovoltaic support structure. Background Technology

[0002] Fixed photovoltaic (PV) supports, currently the most widely used PV support structure, boast high technological maturity and relatively simple structure. They primarily consist of hot-dip galvanized steel components (such as columns, beams, and braces) and concrete foundations (or counterweights), with PV modules secured by bolts. While this structure meets basic support requirements, it suffers from drawbacks in terms of land resource utilization efficiency in confined spaces. On-site casting of concrete foundations or precast concrete counterweights are common solutions to ensure support stability. Large-scale PV power plants require massive amounts of concrete. Current fixed PV supports rely on high-carbon-emission galvanized steel and concrete material systems, creating an environmental burden throughout their entire lifecycle. Their inherent structural layout and space-occupying characteristics limit the PV installed capacity and power generation output per unit of land in confined spaces. These two core drawbacks collectively drive up the levelized cost of electricity (LCOE) of PV systems, restricting their competitiveness in land-scarce or distributed scenarios.

[0003] Chinese patent publication number CN117997228A, entitled "A Multi-Layer Flexible Photovoltaic Tracking Support System," describes a structure where columns are horizontally connected by flexible ropes, photovoltaic modules are laid on these ropes, and supports at the top of the columns are connected to the columns via bearing devices. The flexible ropes are fixedly connected to both ends of the supports. Below the supports and flexible ropes is a diagonal transmission reinforcement system, including transmission purlins and a transmission connection reinforcement structure. The transmission purlins are fixedly connected to the columns via a rotating device and are also connected to a power source. The upper ends of the transmission connection reinforcement structure are connected to the supports and flexible ropes, respectively, and the transmission connection reinforcement structure is fixedly connected to the transmission purlins. While this patent application can function as a support, it cannot fully utilize the space between the upper and lower layers, and the foundation requires a large amount of concrete. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, the purpose of this utility model is to provide a photovoltaic support structure. By setting multiple layers and staggering the top and bottom supports in the horizontal direction, it can avoid large-area shading of the bottom photovoltaic panels. At the same time, by fixing the columns with sleeves and bases, it can reduce the use of concrete.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A photovoltaic support includes two bases, each base having a column sleeve. A column is installed within the column sleeve. Each column is connected to a bottom cantilever beam. A second bottom crossbeam connects the ends of the two bottom cantilever beams, and a first bottom crossbeam connects the two columns. A bottom inclined beam connects the first and second bottom crossbeams. Each column is also connected to a top cantilever beam. The middle of the top cantilever beam is connected to the column, one end of which is connected to the first top column, and the other end is connected to the second top column. The first and second top columns are connected by a top inclined beam.

[0006] Optionally, photovoltaic panels are laid on the bottom inclined beam and on the top inclined beam.

[0007] Optionally, an embedded plate is provided between the base and the column sleeve, and an embedded anchor is embedded in the base that penetrates the embedded plate; a first connecting rod is installed on the column sleeve that penetrates the side wall of the cylinder, and the first connecting rod penetrates the embedded anchor.

[0008] Optionally, each bottom cantilever beam is connected to an upright plate, the bottom of which is connected to the bottom cantilever beam and the top of which is connected to the bottom of the bottom inclined beam. The two ends of the bottom second crossbeam are respectively connected to the middle of the upright plates on the two columns.

[0009] Optionally, a plurality of clamps are provided on the bottom second crossbeam between the two columns, and the two clamps are connected to the bottom of a bottom inclined beam by a second connecting rod, and the top of the bottom inclined beam is connected to the bottom first crossbeam by two clamps and a second connecting rod.

[0010] Optionally, a third top beam connects the middle of the two top first columns, and a first top beam connects the upper parts of the two top second columns.

[0011] Optionally, a plurality of clamps are installed on the top third crossbeam between the two top first columns, and the two clamps are connected to the bottom of a top inclined beam by a second connecting rod, and the top of the top inclined beam is connected to the top first crossbeam by the two clamps and the second connecting rod.

[0012] Optionally, a top second crossbeam connects the tops of the two columns.

[0013] Optionally, the column sleeve includes a cylinder, and each side wall of the cylinder is connected to a support plate.

[0014] Optionally, the columns, bottom cantilever beams, bottom second crossbeams, bottom first crossbeams, second crossbeams, bottom inclined beams, top cantilever beams, top first columns, top second columns, and top inclined beams are all made of wood.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention connects the middle of the top cantilever beam to the column, avoiding the problem of large-area shading of the bottom photovoltaic panels. By setting column sleeves on the base and fixing the column through the sleeves, this invention minimizes the amount of concrete used in the foundation. It increases land utilization within limited space, multiplying the installed capacity per unit area. The double-layer staggered layout solves the problem of second-layer shading. It surpasses fixed-support technology in three dimensions: environmental friendliness, space efficiency, and economy, and is particularly suitable for distributed scenarios with scarce land and the need for rapid deployment of temporary projects.
