[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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 making creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 3 As shown, an embodiment of the present invention provides a photovoltaic array soil and water conservation three-dimensional structure system, including:

[0026] The photovoltaic array 1 comprises a plurality of photovoltaic panels 11 arranged at an angle, and a guide plate 12 is provided at the bottom of each photovoltaic panel 11;

[0027] A photovoltaic bracket 2, one end of which is fixed in the soil and the other end is fixed below the photovoltaic panel 11;

[0028] One end of the root-like anchor column 3 is fixed in the soil, and the other end is fixed under the guide plate 12. A connector 13 is provided at the bottom of the guide plate 12. The water from the photovoltaic panel 11 passes through the guide plate 12 and the connector 13 to the root-like anchor column 3 and flows into the soil.

[0029] In this embodiment, by setting a connector 13 at the bottom of the guide plate 12 and setting a root-like anchor column 3 below the guide plate 12, the water on the photovoltaic panel 11 can be converged, and the converged water can be introduced into the soil through the root-like anchor column 3, thereby reducing the scattered flow impact of water on the soil. That is, the above technical solution can solve the problem of soil erosion caused by rainwater erosion under the photovoltaic panel 11.

[0030] In some embodiments, the guide plate 12 and the photovoltaic panel 11 are connected in a manner compatible with bolts, snaps, or magnets, and the distance between the two can be adjusted to 10 to 30 cm.

[0031] In some embodiments, the outer wall of the guide plate 12 is provided with reinforcing ribs to enhance the structural strength of the guide plate 12 .

[0032] In some embodiments, the guide plate 12 may be made of carbon fiber composite material or recycled plastic with a thickness of 1 to 3 mm.

[0033] like Figure 4 As shown, in one embodiment of the present invention, the outer periphery of the root anchor column 3 is provided with a spiral groove 31. Such a configuration can induce rainwater to form a wall-attached flow, thereby preventing scouring around the column.

[0034] In some embodiments, the depth of the spiral groove 31 is 2 to 5 mm.

[0035] In some embodiments, the spiral groove 31 may be designed as a bidirectional spiral, a fractal groove, or a staggered grid structure, which is not specifically limited here.

[0036] like Figure 5 As shown, in one embodiment of the present invention, a hollow cavity is provided within the root-like anchor column 3. A connector 13 communicates with the guide plate 12 and the hollow cavity, respectively. The hollow cavity is filled with a water-swelling material 32. This arrangement, combined with the spiral groove 31, forms a mechanical-chemical synergistic anchoring mechanism, maintaining a contact stress greater than 80 kPa during dry-wet cycles, improving pullout resistance and fundamentally addressing anchor failure caused by soil debonding. In other words, the spiral groove 31 increases the contact area, and the expansion of the water-swelling material 32 generates radial compressive force, thereby resolving the problem of soil debonding.

[0037] In one embodiment of the present invention, the guide plate 12 and the connector 13 are integrally formed, and the connector 13 and the pseudo-root anchor column 3 are threaded, plug-fitted, or snap-fitted.

[0038] In some embodiments, the guide plate 12 and the connector 13 may also be in the form of a screw-nut combination or a concave-convex clamp combination, which is not specifically limited here.

[0039] In one embodiment of the present invention, the water-swellable material 32 includes at least one of a water-swellable resin, a hydrogel, and a bentonite composite. The water-swellable resin increases in volume by 300% when exposed to water, while the hydrogel and bentonite composite increase in volume by 200-500% when exposed to water.

[0040] In one embodiment of the present invention, the portion of the root-like anchor column 3 located in the soil is provided with a plurality of first through-holes 33 extending through the cylindrical surface. This arrangement allows the water-swellable material 32 to expand downward and outward through the first through-holes 33 due to the restraint of the root-like anchor column 3, thereby increasing the pullout resistance.

[0041] like Figure 6 and Figure 7 As shown, in one embodiment of the present invention, multiple infiltration structures 4 are provided in the soil, each of which is located directly below a root-like anchor column 3. Multiple second through holes 41 are provided around the infiltration structure 4. This arrangement can filter impurities in rainwater.

[0042] In one embodiment of the present invention, the infiltration structure 4 is in the shape of an inverted cone, and the taper ratio is 1:5 to 1:10. In this way, the inverted cone structure produces a Venturi effect to accelerate infiltration and achieve physical infiltration of rainwater.

[0043] In one embodiment of the present invention, the interior of the percolation structure 4 is filled with a magnetic biochar material loaded with nitrogen-fixing bacteria or a red mud-based porous material loaded with phosphorus-fixing bacteria. This arrangement allows the magnetic particles to release charged ions in rainwater, promoting the formation of soil aggregates and increasing the organic matter content, thereby facilitating the improvement of soil biomass.

[0044] In some embodiments, the nitrogen-fixing bacteria loading is ≥10 5 CFU / g, and the magnetic intensity of biochar is 5-10emu / g.

[0045] In one embodiment of the present invention, the plurality of infiltration structures 4 form a grid structure arranged in a diamond, honeycomb or radial pattern, which can increase the stability of the soil.

[0046] In summary, the technical innovations of the technical solution of the present invention include the following dimensions:

[0047] 1) Structural dimension: Establish a three-level linkage system of "plate edge-column-ground" (the plate edge is the guide plate 12, the column is the root anchor column 3, and the ground is the soil reinforcement grid);

[0048] 2) Material dimension: functional modification of water-absorbing resin and magnetic biochar;

[0049] 3) Functional dimension: triple synergy of dynamic response (guide plate 12), mechanical reinforcement (resin), and ecological restoration (biochar).

[0050] For example, measured data from the Gonghe Photovoltaic Industrial Park in Qinghai shows:

[0051] Diversion efficiency: Under 50mm / h rainstorm conditions, the present invention reduces the impact kinetic energy of rainwater from 36J / m 2 Reduced to 2.7 J / m 2 (92.5% decrease)

[0052] Soil stability: After the resin expands, the shear strength of the soil around the column is increased to 186kPa (the traditional solution is only 52kPa)

[0053] Ecological benefits: Within three months, the soil organic matter content in the infiltration matrix area increased from 0.8% to 1.6%, and the earthworm density reached 24 / m 2 .

[0054] It should be noted that, in this article, relational terms such as first and second are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical factors in the process, method, article or device comprising the elements.

[0055] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is intended only to illustrate the technical solution of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included within the scope of protection of the present invention.
