Description

TECHNICAL FIELD

[0001] The utility model relates to the field of solar power supply, especially relates to grassland restoration movable type imitative plant root system rainwater collecting and evaporation reducing solar panel support. BACKGROUND

[0002] China's grassland area is vast, reaching 400 million hectares, accounting for 41.7% of the land area, which as the largest terrestrial ecosystem occupies an extremely prominent strategic position in safeguarding ecological security, food security and promoting Chinese grassland civilization. However, for a long time, due to the lack of understanding of the ecological function of grassland, excessive dependence on its production function, more than 90% of the grassland has appeared in varying degrees of degradation, and the grassland ecosystem has been severely damaged. Although people have realized the seriousness of the problem and actively carried out management work, but the current management speed is far from keeping up with the degradation speed.

[0003] In the process of continuous exploration of grassland ecological protection, it is found that the grassland has very rich light resources, which makes the use of solar power generation an important idea to solve the energy problem of grassland ecological protection. As a clean energy, solar energy has great potential in the application of grassland areas, which can reduce the dependence on traditional energy and reduce environmental pollution.

[0004] However, the natural conditions in the grassland area are special, and the wind is a prominent feature. This condition greatly limits the installation method of the solar panel support on the soil, so it is often necessary to first drive a cement pile to provide sufficient stability before installing the solar panel support. However, cement itself has complex chemical composition, and after contacting with water, it will release alkaline substances, thereby changing the pH of the soil. This change has a negative impact on the grassland soil environment, is not conducive to the growth of grassland vegetation, and may also damage the microbial community in the soil, thereby affecting the balance of the entire grassland ecosystem. Moreover, the construction and use process of the cement pile may also cause a certain degree of damage to the grassland surface, affect the vegetation coverage, and cause problems such as soil erosion. In addition, the cement pile is a permanent facility, once installed, it is difficult to move or adjust, and the flexibility is poor, which is not conducive to the dynamic management and optimization of grassland ecological protection work. Therefore, it is very important to find a solution that meets the stability requirements of the solar panel support and meets the ecological friendly principle for grassland ecological protection work.

[0005] Chinese patent CN202473954 discloses a solar support, comprising a plurality of support frames, the support frame is fixed with a plurality of horizontal rods, the horizontal rod is provided with a pressing block, the pressing block is in the shape of an inverted "π", the lower end of the support frame is also welded with a reinforcing rib, and the bottom end of the support frame is provided with a foot pad.

[0029] This utility model proposes a movable, plant-root-inspired solar panel support for grassland restoration, which can stably support solar panels without relying on cement pillars. Example

[0030] Firstly, regarding the main body of the support frame, its upper part is used to support the solar panel base, such as... Figure 1 The lower part is a plant root-like structure composed of a thickened, trumpet-shaped structure 1 and a cross-line structure. This optimized design increases resistance and enhances stability after being inserted into the soil.

[0031] Furthermore, such as Figure 1 The root-like structure includes a ring of 4-10 outward-extending, tapering conical protrusions 3. These protrusions 3 mimic the morphology of the taproot of a plant, with their roots originating from the outer wall of the thickened structure 1 at the base of the support and gradually tapering radially outwards. Figure 3 Furthermore, the surface features a textured surface designed to increase friction. This texture includes, but is not limited to, interlaced fine grooves and raised particles, significantly enhancing friction and adhesion with the soil. The protruding structures 3 are connected by a mesh structure 2 made of the same material. This mesh structure 2 mimics the root structure of plant roots and is woven from high-strength, corrosion-resistant metal wires.Figure 1 The mesh is rhomboid or rectangular, and the wire diameter and mesh size are selected according to the soil type. In areas with loose soil, such as sandy soil or loess soil, the mesh structure 2 needs to withstand greater deformation forces. To prevent excessive deformation or damage to the mesh structure 2 under soil pressure, a thicker wire diameter should be selected, such as around 3-5 mm. A thicker wire diameter provides higher tensile and bending strength, allowing the mesh structure 2 to effectively distribute the pressure on the support and maintain structural stability even in loose soil. Regarding the mesh size, considering the weak bonding force between loose soil particles, to avoid excessive loss of soil particles from the mesh and subsequent support sinking, a smaller mesh should be selected, generally a square mesh with a side length of 20-30 mm or a rhomboid mesh with a short diagonal length of 20-30 mm. This mesh size better constrains the soil and, when the mesh structure 2 is under stress, allows for a more even distribution of stress at each connection point, enhancing the anchoring ability of the support base in loose soil. In environments with dense soil, where the soil's supporting force is already strong, the deformation force required by the mesh structure 2 is smaller. To reduce material costs, the wire diameter can be appropriately reduced to 2-3mm, and the mesh size can be appropriately increased, using a square mesh with a side length of 30-40mm or a rhomboid mesh with a short diagonal length of 30-40mm. Furthermore, a reinforced weaving process is employed at key stress points, such as increasing the number of winding turns or inserting reinforcing wires. This allows the mesh structure 2 to connect all protruding structures 3 into an organic, integrated stress-bearing system. When the support is subjected to external forces, the stress can be efficiently distributed to each protruding structure 3 through the mesh structure 2, and then transferred to the soil, working together to stably fix the support in the soil.

[0032] Furthermore, the end of the protruding structure 3 is configured as a cylindrical structure 4 with an external helical pattern on its surface. A wear-resistant coating is applied to the threaded surface to reduce wear during the installation and removal of the moving wheels and to ensure a tight and smooth connection. The moving wheels, which are adapted to the external helical structure and are used to move the support, include rubber tires and aluminum alloy hubs. Before burying the support in the soil, the moving wheels need to be removed because they are threaded to the support. To prevent damage to the moving wheels during burial or in the soil, they are stored separately, and a special rubber protective sleeve is placed over the helical pattern at the end of the support.

[0033] Example 2: The support frame proposed in this utility model is applied to grassland ecological protection.

[0034] For the ecological protection of grasslands, it is crucial to first understand the environment and then develop methods to address environmental challenges. In this regard, we conducted on-site environmental investigations and found that the Bashang area of ​​Zhangjiakou, Hebei Province, is an arid and windy grassland region. Located at the boundary of the interaction between continental and monsoon climates in my country, the Bashang area combines the production characteristics of dryland agriculture and grassland animal husbandry. It is also an important water source for the downwind Beijing-Tianjin area and a vital ecological security barrier to prevent soil erosion and desertification, thus possessing significant ecological strategic importance.

[0035] Considering the ecological environment and grassland conditions, a grassland ecological protection method is proposed. This method utilizes solar panels for grassland shading and solar power generation, and collects rainwater through a rain collection device. The rainwater is then sprayed using a rotary sprinkler irrigation machine, whose power is derived from the solar panels, thus optimizing the utilization of water and light resources. Previously, installing solar panels on grasslands required erecting cement pillars, but cement itself causes significant pollution to the grassland soil, contradicting the purpose of ecological protection. To ensure the stable installation of solar panels without using cement, this grassland ecological protection experiment used the proposed movable, plant root-inspired rainwater collection and evaporation reduction solar panel support for grassland restoration. The specific process is as follows:

[0036] First, the experimental environment was set up, with a solar panel slope of 37 degrees and a spacing of 12 meters between the two rows of solar panel supports. Each solar panel measures 1.65 meters × 0.95 meters, and four panels are grouped together, with each group measuring 1.65 meters × 3.8 meters. Considering convenience and environmental factors, a simplified version of the solar panel support proposed in this invention was used. The original flared section and protruding structure 3 were simply replaced, and the area at the tail was increased, replacing the enlarged area of ​​the original flared section at the bottom of the support. Wire mesh was used to wrap around the bottom, replacing the original mesh structure 2. Based on this simplification, a support with four protruding structures 3 and a total length of 3 meters was selected. One-third to one-half of the support was buried in the soil to ensure stability. The vertical projection of the solar panel on the south side of the support is 1.6 meters, and the vertical projection of the solar panel on the north side is 1.6 meters, totaling 3.2 meters. Currently, the grass growth dividing line is 1.2 meters south of the support and 3.2 meters north of the support, totaling 4.4 meters. The grass growth on the north side of the support is significantly better than that on the south side.

[0037] This experiment aims to protect the grassland ecosystem through multi-faceted resource utilization. It mainly consists of three parts: energy harvesting, ground-based energy storage, and rainwater storage. Energy harvesting primarily involves collecting and converting solar energy, using solar panels, solar panel bases, and the solar panel support frame proposed in this invention. The solar panels are arranged in a row-and-column pattern, taking into account the grassland's climate characteristics, topography, lighting conditions, and ease of maintenance, selecting sunny, unobstructed grassland areas. A drainage channel is installed below the solar panels to collect rainwater, which then flows into a water tank within the ground-based energy storage system. The ground-based energy storage includes a battery pack for storing electrical energy and a water tank for storing rainwater. The battery pack is connected to a rotary sprinkler, and the water tank is connected to a reservoir responsible for rainwater storage. The rotary sprinkler, connected to the reservoir, effectively manages the unevenly distributed rainfall and sunlight in time and space through solar panel shading, power generation, and rainwater collection, fully utilizing excess sunlight and uneven water resources in the grassland environment.

[0038] While collecting solar energy and converting it into electrical energy, the solar panels also create shade for the grass below, dividing the grassland into fully shaded, partially shaded, and unshaded areas. Each area is labeled to facilitate subsequent comparative experiments.

[0039] After a period of time, biomass data of the grassland was collected, showing that the average grass height in the shaded plots was 40 cm, and in the unshaded plots it was 10 cm. Specific data are shown in Table 1.

[0040] Table 1. Biomass Statistics

[0041]

[0042] To verify the direct impact of shading on grassland land, we conducted soil sampling on the grassland quadrats. The specific data are shown in Table 2.

[0045] The data analysis revealed significant differences in grass height and biomass between shaded and unshaded plots. Shaded areas in grassland regions effectively shield plants from excessive sunlight, preventing the risk of high temperatures inhibiting growth or even causing localized drought. Furthermore, as sunlight weakens and decreases, the direction of sunlight gradually aligns with the solar panels, maximizing the positive effects of sunlight on plant growth. This also facilitates irrigation, significantly increasing soil moisture content. Water plays a crucial role in plant growth, especially root development. A well-developed root system allows for better nutrient absorption and better soil adhesion, reducing soil erosion and enhancing the plant's resistance to lodging.

[0046] This embodiment combines solar panels, energy storage devices, and water storage devices to efficiently collect water and sunlight resources from the grassland environment. Through artificial intervention, these resources are rationally allocated, achieving "full collection and on-demand distribution" of rainwater. Light intensity and duration are controlled, creating a stable and more suitable environment for plant growth. This environment is flexible and adaptable to different environments. The entire ecological restoration process uses solar energy, achieving zero energy input and avoiding environmental pollution from fossil fuels. No external energy input is required, significantly reducing costs and ensuring the sustainability and universality of this method.

[0047] In this embodiment, since the solar panel support has a high density, using cement pillars to assist in the installation of the solar panel support would be very detrimental to the pollution of the grassland and the growth of plants. However, using the solar panel support proposed in this utility model eliminates the need for cement pillars, and the root-like design ensures the stability of the solar panel even in windy grassland environments.

[0048] The installation process of the movable, plant root-inspired rainwater harvesting and evaporation reduction solar panel bracket for grassland restoration proposed in this utility model is as follows: Before use, transport the bracket to the installation location, remove the casters, and install the provided rubber protective sleeves on the external threads; dig a hole in the ground according to the length of the protruding structure 3, which is 1 / 3 to 1 / 2 of the total length of the bracket, and bury the bracket in the hole.

[0049] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0050] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
