Description

Technical Field

[0001] This utility model relates to a photovoltaic support structure, and more particularly to a vertical photovoltaic support structure installed on a slope with concrete slope protection grids. Background Technology

[0002] With the vigorous promotion of photovoltaic power generation, in order to save precious land resources, some photovoltaic power stations have been deployed on existing structures, giving these structures double the value. Some mountain roads are located at the foot of mountains, and some industrial and agricultural parks built in mountain valleys are also situated at the bottom of steep slopes. To protect the safety of these roads and parks and prevent landslides, concrete block revetments have been installed on these steep slopes. Precast concrete block revetments are constructed using factory-produced concrete blocks, assembled and fixed on-site on the mountainside. This method of revetment has certain advantages. The flexibility of concrete blocks allows them to adapt to small deformations in the foundation, while also providing good permeability to balance water pressure and reduce water damage to the slope. Concrete block slope protection is efficient to construct, easy to control in terms of quality, and can create landscape effects through different block shapes and colors. Installing photovoltaic modules on slopes already protected by concrete blocks can further prevent soil erosion, reuse the slope, and reduce the construction cost of photovoltaic supports, achieving three benefits in one go. However, how to utilize existing resources to deploy photovoltaic supports is a problem that needs to be solved on site. Summary of the Invention

[0003] This utility model provides a vertical photovoltaic support structure that is installed on a concrete block slope protection grid, solving the technical problem of how to install photovoltaic supports using precast concrete block slope protection.

[0004] This utility model solves the above technical problems through the following technical solution:

[0005] A vertical photovoltaic support system installed on a slope protection grid of concrete blocks includes a slope with precast concrete blocks arranged in a grid pattern. A square base plate is installed on each precast concrete block, and the base plate is fixed to the precast concrete blocks by expansion bolts. A connecting sleeve is welded to the center of the top surface of the square base plate, a central column is installed on the connecting sleeve, and a triangular connector is installed at the top of the central column. The structure is connected to a central crossbeam; a corrugated pipe foundation pit is set on the ground at the bottom of the slope, a corrugated pipe is set in the corrugated pipe foundation pit, concrete is poured into the corrugated pipe, a pre-embedded sleeve is embedded at the top of the concrete, a bottom column is connected to the pre-embedded sleeve, and a bottom crossbeam is connected to the top of the bottom column; a vertical purlin is connected between the bottom crossbeam and the central crossbeam; a micro-hole cast-in-place pile is set at the top of the slope, and an anchor cable is connected between the micro-hole cast-in-place pile and the central crossbeam.

[0006] On the slope, connecting sleeves are installed at intervals along the vertical direction of the slope. Each connecting sleeve is fixedly connected to the corresponding precast concrete block of the slope protection. Two rows of connecting sleeves are arranged parallel to each other on the slope, and each connecting sleeve is equipped with a central column. Two corrugated pipe foundation pits are set in parallel on the ground at the bottom of the slope. Corrugated pipe piles and bottom columns are set in each corrugated pipe foundation pit. A bottom crossbeam is set between the two bottom columns. Photovoltaic power generation modules are installed on the vertical purlins.

The use of vertical supports achieves high-efficiency utilization of the slope protection area, significantly saves on the steel structure investment of photovoltaic supports, solves the stability problem of photovoltaic supports, and further prevents soil erosion and landslides on the slope.

[0012] The present invention will now be described in detail:

[0013] A vertical photovoltaic support structure installed on a slope protection grid of concrete blocks includes a slope 1. Precast concrete blocks 2 arranged in a grid pattern are laid on the slope 1. The precast concrete blocks 2 have undergone foundation reinforcement and are tightly integrated with the slope 1, stabilizing the slope. A square base plate 3 is installed on each precast concrete block 2, fixed to the precast concrete blocks 2 by expansion bolts 5. A connecting sleeve 4 is welded to the center of the top surface of the square base plate 3. A central column 6 is installed on the connecting sleeve. A triangular connector 7 is installed at the top of the central column 6, and a central crossbeam 8 is connected to the triangular connector 7. The central column 6 is vertically positioned and serves as the main support column for the photovoltaic modules. A corrugated pipe pit 13 is set on the ground at the bottom of the slope 1. A corrugated pipe 14 is installed in the corrugated pipe pit 13, and concrete 15 is cast-in-place inside the corrugated pipe 14. An embedded sleeve 16 is pre-embedded at the top of the concrete 15 inside the pipe. A bottom column 17 is connected to the embedded sleeve 16. A bottom crossbeam 18 is connected to the top of the bottom column 17. Due to the steep slope, the weight of the vertical photovoltaic support set on it will be concentrated on the two bottom columns 17. Therefore, the bottom columns 17 are set on the corrugated pipe pile foundation. The diameter of the corrugated pipe is about 1200 mm. A steel cage is set in it. A large amount of concrete is poured in the pipe to support and stabilize the weight of the entire photovoltaic support. Two to three vertical purlins 9 are connected between the bottom crossbeam 18 and the middle crossbeam 8. The photovoltaic modules are installed between the parallel vertical purlins 9. Micro-hole grouting piles 11 are set at the top of the slope 1. An anchor cable 12 is connected between the micro-hole grouting pile 11 and the middle crossbeam 8. The two anchor cables at the top of the slope play a pulling role on the entire photovoltaic support, thereby stabilizing the photovoltaic support by pulling up and supporting down.

[0014] On slope 1, connecting sleeves 4 are spaced apart along the vertical direction of slope 1. Each connecting sleeve 4 is fixedly connected to the corresponding precast concrete block 2 of the slope protection. Two rows of connecting sleeves 4 are parallel to each other on slope 1. Each connecting sleeve 4 is equipped with a central column 6. Two corrugated pipe foundation pits 13 are arranged in parallel on the ground at the bottom of slope 1. Corrugated pipe pile foundations and bottom columns 17 are set in each corrugated pipe foundation pit 13. A bottom crossbeam 18 is set between the two bottom columns. Photovoltaic power generation modules 10 are installed on the vertical purlins 9. Two micro-hole cast-in-place piles 11 are arranged in parallel at the top of slope 1. An anchor cable 12 is connected between each micro-hole cast-in-place pile 11 and the central crossbeam 8.

[0015] External concrete is poured into the corrugated pipe foundation pit 13 outside the corrugated pipe 14 to make the entire corrugated pipe pile foundation more stable.
