Description

Technical Field

[0001] The present disclosure relates to the field of desert photovoltaic fixing technology, and in particular to a fixing device for desert sand and a photovoltaic module having the same. Background Art

[0002] With the rapid development of clean energy technology, photovoltaic power generation technology has attracted more and more attention. Since there is a large amount of light energy that can be used in desert sandy areas, there are great challenges in the design and installation of photovoltaic module fixtures in soft geological environments such as desert sandy areas. Due to the loose structure of the sand and the lack of viscosity, traditional foundation fixing methods, such as digging pits and piling, are difficult to provide sufficient support and stability. These methods usually require excavation or deeper foundation treatment, which not only increases the complexity and cost of construction, but also easily causes damage to the ecological environment.

[0003] The existing various sand foundation schemes have low construction efficiency and high cost. In addition, their construction process is highly dependent on machinery, and mechanical rolling causes extremely serious damage to the surface sand vegetation. The existing schemes are prone to uneven settlement because each column base is independently set and lacks an overall design. Furthermore, the surface matrix of the cylindrical foundation of the traditional scheme is easily hollowed out and eroded by the surface wind circulation, resulting in a decrease in its anti-overturning ability and reducing the stability and pull-out resistance of the fixing device. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies in the related art and to provide a fixing device for desert sand and a photovoltaic module having the same, thereby improving the construction efficiency of the fixing device, reducing the damage to vegetation in the desert sand during installation, and enhancing the anti-subsidence ability, stability and anti-pulling ability of the fixing device.

[0045] First, the embodiment of the present disclosure provides a fixing device for desert sand, which may include a support column and at least two gripping assemblies. Among them, at least two gripping assemblies may be arranged to be rotatably connected to one end of the support column, and the rotation plane is parallel to the extension direction of the support column, and the support column passes through the rotation plane, and the gripping assembly can be detachably connected to the gripping assembly on at least one other set of fixing devices.

[0047] refer to Figures 1 to 10As shown, the fixture 0 for desert sand in the embodiment of the present disclosure may include a support column 1 and a grip assembly 2. Among them, the support column 1, as the main supporting body of the fixture 0, may be a column structure made of corrosion-resistant materials. For example, the corrosion-resistant material may be aluminum alloy, carbon steel, stainless steel, etc. The support column 1 may be cylindrical, square column, or prismatic. This embodiment does not specifically limit the manufacturing material and shape of the support column 1. For ease of understanding, the accompanying drawings and subsequent embodiments are all described by taking the support column 1 as a cylindrical shape as an example.

[0048] The fixing device 0 may be provided with at least two gripping assemblies 2, for example, two gripping assemblies 2 may be provided, or four gripping assemblies 2 may be provided. It is understandable that those skilled in the art may also provide six, eight or even more gripping assemblies 2 according to actual needs. The present exemplary embodiment does not specifically limit the number of gripping assemblies 2. The gripping assembly 2 may be provided to be rotatably connected to one end of the support column 1, and the rotation plane of the gripping assembly 2 is parallel to the extension direction of the support column 1, and the support column 1 passes through the rotation plane. When in use, the gripping assembly 2 on the fixing device 0 can be detachably connected to the gripping assembly 2 on at least one other group of fixing devices 0, thereby realizing a combined connection between multiple fixing devices 0 to form a large-area interlocking structure.

[0049] Next, combine Figures 1 to 10 The fixing device 0 provided in the embodiment of the present disclosure is described in detail.

[0050] In some embodiments of the present disclosure, reference Figure 1 , Figure 2 , Figure 3 , Figure 8 and Fig. 9 As shown, the support column 1 may include a column body 11 and at least two connecting wing plates 12. Wherein:

[0051] The column body 11 may be the main structure forming the support column 1, such as the column body 11 may be a cylindrical column, one end of which may be a cylinder, mainly used to connect with the object to be supported and fixed, for example, the object to be supported and fixed may be a photovoltaic panel, and the photovoltaic panel may be connected to the cylindrical end of the column body 11 by a connector such as a clip, a lock, or a connector. The other end of the column body 11 may be a conical cylinder, which may serve as the ground insertion end 111 of the column body 11, so that the column body 11 can be easily inserted into the ground in a sandy environment.

[0052] The connecting wing plate 12 can be provided at the ground-inserting end 111 of the column body 11, one side of the connecting wing plate 12 can be fixedly connected to the outer surface of the conical cylinder, and a first connecting portion 121 is provided on the side away from the outer surface of the conical cylinder, and the gripping assembly 2 can be rotatably connected to the ground-inserting end 111 of the column body 11 through the first connecting portion 121. For example, the first connecting portion 121 can be a connecting hole, and the first connecting portion 121 can be rotatably connected to the ground-inserting end 111 of the column body 11 by bolt fixing; the first connecting portion 121 can also be a connecting protrusion, and the connecting protrusion can be rotatably connected to the ground-inserting end 111 of the column body 11. This exemplary embodiment does not specifically limit the rotational connection method between the first connecting portion 121 and the ground-inserting end 111 of the column body 11.

[0053] By designing the ground insertion end 111 of the column body 11 to be a conical cylinder, it is beneficial to reduce the resistance when the support column 1 is inserted into the sand, and it is more smoothly fixed on the ground, reducing the construction difficulty. At the same time, at least two connecting wing plates 12 are provided to provide a stable support point for the connection of the gripping assembly 2, facilitate the installation of the gripping assembly 2, and also increase the gripping area of ​​the gripping assembly 2, improve the connection stability between the gripping assembly 2 and the support column 1, and effectively enhance the stability of the overall structure of the support column 1 fixed to the ground.

[0054] Optionally, the connecting wing plate 12 is a triangular wing plate. Generally, the number of the connecting wing plates 12 can be matched with the number of the gripping components 2. In this embodiment, the number of the triangular wing plates, i.e., the connecting wing plates 12, can be four, and two opposite triangular wing plates are on the same plane and together form an inverted triangle whose vertex coincides with the tip of the conical cylinder, and the two planes where the four connecting wing plates 12 are respectively located are perpendicular, that is, the four connecting wing plates 12 are evenly arranged on the outer surface of the conical cylinder of the ground insertion end 111.

[0055] The first connection portion 121 may be disposed on a tip of the triangular wing plate away from the conical cylinder. The first connection portion 121 may be used to rotatably connect the grip assembly 2 to the triangular wing plate.

[0056] By setting four triangular wing plates symmetrically and evenly distributed at the ground-inserting end 111 of the column body 11, so that they are distributed on different planes, the column body 11 has supporting forces in more directions, and the torsion resistance of the support column 1 is enhanced. At the same time, setting the first connecting portion 121 at a position away from the tip of the cone cylinder can provide a larger distance for setting the gripping assembly 2, so that a larger gripping assembly 2 can be set, and the gripping force of the gripping assembly 2 can be increased, thereby increasing the contact area between the gripping assembly 2 and the ground and improving the gripping stability; at the same time, the first connecting portion 121 is set at a position away from the tip of the cone cylinder, which can provide a better fulcrum for the gripping assembly 2 to complete the gripping operation, so that the gripping assembly can be rotated reliably and easily, achieving the best gripping effect and improving construction efficiency.

[0057] In some embodiments of the present disclosure, reference Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, the grip assembly 2 may include a fan-shaped connecting plate 21 and a curved resistance plate 22. Wherein:

[0058] The sector-shaped connecting plate 21 may include a sector-shaped plate 211 having an arc-shaped outer edge.

[0059] The curved resistance plate 22 may include an inner curved surface and an outer curved surface. The curvature of the inner curved surface may match the curvature of the arc-shaped outer edge. The curved resistance plate 22 may be fixedly connected to the arc-shaped outer edge via the inner curved surface.

[0060] By designing the grip assembly 2 as a structure consisting of a fan-shaped connecting plate 21 and a curved resistance plate 22, the grip assembly 2 can be inserted into the sand more conveniently; at the same time, this structure can surround more sand and soil on the inner side of the grip assembly 2, thereby increasing the gripping force of the grip assembly 2 when it is rotated and inserted into the sand; the arc-shaped outer edge of the fan-shaped plate 211 matches the inner curved surface of the curved resistance plate 22, making the structure of the grip assembly 2 more stable, while also enhancing the resistance effect of the grip assembly 2 in the sand, thereby improving the pull-out resistance and anti-overturning ability of the fixing device 0.

[0061] Optional, reference Figures 4 to 6 As shown, the fan-shaped connecting plate 21 may include a second connecting portion 212, and the second connecting portion 212 may be arranged at a position close to the center of the fan-shaped plate 211. The grip assembly 2 may be connected to the first connecting portion 121 of the triangular wing plate through the second connecting portion 212, and the grip assembly 2 may be able to rotate around the connection position of the second connecting portion 212 and the first connecting portion 121.

[0062] Among them, both the first connection part 121 and the second connection part 212 can be connection holes, and the connection between the first connection part 121 and the second connection part 212 can be achieved by connecting parts such as bolts, so that the grip assembly 2 can rotate around the connection position of the second connection part 212 and the first connection part 121; of course, the first connection part 121 can be a connection hole, and the second connection part 212 can be a connection protrusion, and the connection between the first connection part 121 and the second connection part 212 is achieved by buckling the connection hole into the connection protrusion, so that the grip assembly 2 can rotate around the connection position of the second connection part 212 and the first connection part 121 as the center; of course, the first connection part 121 and the second connection part 212 can also be rotatably connected in other ways, and this example embodiment does not specifically limit this.

[0063] By setting the second connection part 212 at the center position of the circle on the fan-shaped connection plate 21, the gripping assembly 2 can reasonably use the lever theorem during the insertion process of the ground, and rotate around the connection position, thereby reducing the difficulty of inserting the gripping assembly 2 into the ground and improving the construction efficiency of the gripping assembly 2. At the same time, the combination of the second connection part and the first connection part enables the gripping assembly 2 to be tightly connected to the support column 1, ensuring the smoothness and stability of its rotation.

[0064] Optional, reference Figures 4 to 6 As shown, the sector-shaped connecting plate 21 may include a connecting arm 213 , and the connecting arm 213 may be formed by extending outward from one end of the sector-shaped plate 211 away from the tip of the conical cylinder.

[0065] The connecting arm 213 may include a third connecting portion 214, and the third connecting portion 214 may be used to be detachably connected to the third connecting portion 214 on at least one other set of fixing devices 0, thereby realizing a combined connection between two sets of fixing devices 0. Figure 5 or Figure 8 As shown, the fixing devices 0 with different numbers of gripping components can be freely combined and spliced ​​through the third connecting parts 214 on the gripping components 2.

[0066] By extending the connecting arm 213 on one side of the fan-shaped connecting plate 21 away from the conical cylinder, on the one hand, the length of the force arm of the gripping assembly 2 when inserted into the ground can be increased, so that the construction personnel can use the lever principle to more conveniently insert the gripping assembly 2 to the appropriate depth, which saves time and effort and does not require the participation of construction machinery. To a certain extent, it can protect the surface sand vegetation in the construction area from damage; on the other hand, additional connection points can be provided, so that different fixing devices 0 can be combined and connected through the third connecting part 214, thereby improving the stability and anti-sedimentation ability between large-area fixing devices; on the other hand, the third connecting part can flexibly realize the assembly connection between the fixing devices 0, which can adapt to different site environments and effectively improve the stability and environmental adaptability of the fixing device 0.

[0067] Optional, reference Figure 1 , Figure 2 , Figures 4 to 10 As shown, the curved surface unfolded shape of the curved resistance plate 22 can be an isosceles triangle. Of course, the curved surface unfolded shape of the curved resistance plate 22 can also be an equilateral triangle or a triangle of any shape, and this exemplary embodiment is not limited thereto.

[0068] The arc-shaped outer edge of the sector plate 211 may coincide with the central symmetry line of the curved resistance plate 22 , so that an end of the sector plate 211 close to the sharp corner of the curved resistance plate 22 and the sharp corner constitute a gripping tip of the gripping assembly 2 .

[0069] By designing the unfolded shape of the curved resistance plate 22 to be an isosceles triangle and making it coincide with the central symmetry line of the fan-shaped plate 211, the resistance when inserted into the sand is reduced, and the embedding depth and gripping force of the curved resistance plate 22 in the sand are improved; at the same time, this structural design can form a gripping tip on the gripping component 2, through which the gripping tip can enable the gripping component 2 to better penetrate the sand, making it easier for the gripping component 2 to reach the specified depth, reducing the construction difficulty and enhancing the fixing effect.

[0070] Optionally, the grip assembly 2 can be in a gripping state when the gripping tip rotates away from the conical cylinder, and the grip assembly 2 is in a resistance fixing state when the gripping tip rotates close to the conical cylinder. When fixing, the grip assembly 2 is rotated while the conical cylinder is inserted deep into the sand, so that the curved resistance plate 22 of the grip assembly 2 is completely inserted below the sand surface, and the grip assembly 2 gradually switches from the gripping state to the resistance fixing state. At this time, the fan-shaped connecting plate 21 of the grip assembly 2 is partially exposed on the sand surface, for example, at least the connecting arm 213 and the third connecting part 214 can be exposed on the sand surface, so that the connecting arm 213 and the third connecting part 214 of the grip assembly 2 on at least one other set of fixing devices 0 can be detachably connected by exposing the connecting arm 213 and the third connecting part 214 exposed on the sand surface, thereby improving the efficiency of the assembly connection between the fixing devices 0 and facilitating subsequent maintenance.

[0071] The grip assembly 2 can be placed in a gripping state and a resistance fixing state by rotating. When the grip tip rotates away from the cone, the grip assembly 2 is in a gripping state, which helps the fixing device 0 to embed into the sand. When the grip tip rotates close to the cone, the grip assembly 2 turns into a resistance fixing state, which increases the gripping force of the fixing device 0 and improves the stability, pull-out resistance and rollover resistance of the fixing device 0. Figure 5 and Figure 8 As shown, after the construction is completed, each grip assembly 2 on the fixing device 0 is in a fixed resistance state. At this time, the grip assembly 2 can form a certain sand retention and fixation area, so that the sand in the area fixed by the fixing device 0 will not be eroded by wind, further improving the stability of the fixing device and protecting the surface environment of the desert sand.

[0072] The embodiment of the present disclosure also provides a photovoltaic assembly for desert sandy land, and the photovoltaic assembly may include a photovoltaic panel and Figures 1 to 10 In any embodiment of the fixing device 0 for desert sand, the photovoltaic panel can be fixedly connected to the fixing device 0, for example, it can be fixedly installed on the end of the support column 1 of the fixing device 0 away from the ground insertion end 111.

[0073] By combining the fixing device with the photovoltaic panel, a stable support can be provided for the photovoltaic module, thereby achieving effective fixation of the photovoltaic module and improving the wind resistance. This structure is not only suitable for desert sand, but can also be extended to other similar environments to provide a reliable fixing foundation for photovoltaic projects.

[0074] It should be understood that the present disclosure does not limit its application to the detailed structure and arrangement of the components proposed in the present disclosure. The present disclosure can have other embodiments and can be implemented and executed in a variety of ways. The aforementioned variations and modifications fall within the scope of the present disclosure. It should be understood that the present disclosure disclosed and defined in the present disclosure extends to all alternative combinations of two or more individual features mentioned or evident in the text and / or the accompanying drawings.
