Description

Technical Field

[0001] This invention relates to the field of windbreak and sand-fixing devices, and in particular to a multifunctional windbreak and sand-fixing vegetation barrier. Background Technology

[0002] Desertification is a natural (non-natural) phenomenon caused by factors such as drought, vegetation destruction, overgrazing, wind erosion, water erosion, and soil salinization, resulting in a decline or loss of soil productivity over large areas.

[0003] Among the main natural factors leading to desertification, drought and strong wind erosion are the most significant. Desertified areas have sparse vegetation, resulting in poor water retention and extremely fragile ecosystems. Current windbreak and sand-fixing devices typically use fixed sand nets or straw checkerboards as physical barriers. While these can slow wind speed and the rate of sandification, they cannot fundamentally restore the ecological environment. Afforestation is one of the effective measures for windbreak and sand fixation. By planting trees, protective forest belts can be formed to block wind and sand erosion and reduce wind speed, thus playing a role in windbreak and sand fixation. However, the drought and water scarcity in desertified areas have always been a technical challenge for afforestation. Sandy surfaces have difficulty effectively retaining rainwater, and without windbreaks, surface rainwater quickly dries up, failing to effectively nourish plants. This results in low survival rates and high costs associated with afforestation. In addition, some drought-resistant desert plants can be sown. The well-developed root system of desert plants grows into the deep sand where the wind is hard to reach to absorb water. The large number of fibrous roots can reduce dust and play a role in windbreak and sand fixation. However, in the seedling stage, desert plants are difficult to take root in the windy environment and grow slowly, which also presents the problem of great difficulty in planting.

[0004] Therefore, how to provide a multifunctional windbreak and sand-fixing vegetation barrier that can effectively establish a physical windbreak and slow down the rate of wind and sand erosion; effectively collect and utilize rainwater for precise irrigation; and has good reliability are problems that urgently need to be solved by those skilled in the art. Summary of the Invention

It utilizes a grass grid laid on the ground to construct a surface windbreak and sand-blocking structure; a solar panel is installed above the grass grid to create an overhead windbreak; the grass grid, solar power generation, and windbreak structure are organically combined to create a three-dimensional windbreak barrier, achieving good windbreak and sand-fixing effects. The grass grid protects the planting area; rainwater collection channels constructed using solar panels and inclined solar frames effectively collect and channel rainwater, allowing it to flow sequentially through a confluence outlet, a drainage channel, and a drainage pipe into the ground for precise irrigation of the planting area, greatly improving rainwater utilization efficiency. This invention effectively establishes a physical windbreak barrier using solar panels, slowing down wind and sand erosion and effectively collecting and utilizing rainwater for precise irrigation. It achieves the triple functions of solar panel power generation, windbreak, and water collection irrigation, and has the advantage of high reliability.

Water entering from the water supply inlet 2121 can sequentially pass through the water supply riser 21, the solar panel mounting frame 22, and the spray nozzle 222 to spray onto the upper surface of the solar panel 3 for rinsing, thereby improving the power generation efficiency of the solar panel 3. The rinsing water sprayed from the spray nozzle 222 then sequentially passes through the rainwater collection outlet 2212, the water guide channel 41, and the water guide pipe 42 into the ground to precisely irrigate the soil layer of the planting area 11, greatly improving the utilization efficiency of the rinsing water of the solar panel 3.

The upper and side ends of the solar panel 3 are sealed and bonded to the inner wall of the corresponding solar panel mounting hole 221 with sealant to reduce manufacturing costs and improve durability; see bending method for details. Figure 6 There is no single bending method; you can design your own method as needed.

Adjacent sets of solar power generation and windbreak structures are spaced apart to reserve space for sunlight in the interval areas. Each set of solar power generation and windbreak structures is equipped with a water guiding component 4.
