Abstract
Description
Technical Field
[0001] The present application relates to the field of waterborne photovoltaic technology, and more specifically, to an anchor block, an anchoring system, and a waterborne photovoltaic system. Background Art
[0002] Currently, the application scenarios for water-based photovoltaic power plants are increasingly diverse, primarily in small and medium-sized lakes, reservoirs, coal mining subsidence areas, and offshore areas. In these scenarios, anchoring systems are crucial for ensuring the stable operation of water-based photovoltaic power plants. However, faced with the complex subsurface soil, traditional concrete anchor blocks often suffer from insufficient horizontal bearing capacity and excessive vertical bearing capacity. Currently, increasing anchor capacity is typically achieved by increasing the size of the concrete anchor blocks, but this approach makes construction economical.
[0003] In summary, how to solve the problem of high construction cost of anchor blocks to ensure anchoring bearing capacity has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content
[0004] In view of this, the present application provides an anchor block, an anchoring system and an above-water photovoltaic system to solve the problem of high construction cost of the anchor block in order to ensure the anchoring bearing capacity.
[0005] In order to achieve the above objectives, this application discloses the following technical solutions:
[0006] In a first aspect, the present application provides an anchor block for underwater anchoring of a water photovoltaic system, comprising an anchor block body, wherein a hollow structure is formed at the bottom of the anchor block body.
[0007] In some embodiments, the hollow structure is configured as a concave cavity recessed from the bottom surface of the anchor block body to the top surface of the anchor block body.
[0008] In some embodiments, the concave cavity is configured to have a structure with a cross-section that gradually decreases from bottom to top along the height direction of the anchor block body.
[0009] In some embodiments, the concave cavity is configured as a rectangular groove, and the side groove walls of the rectangular groove are inclined surfaces or smooth transition surfaces.
[0010] In some embodiments, the concave cavity is configured to have a structure with equal cross-section along the height direction of the anchor block body.
[0011] In some embodiments, the hollow structure is configured as a trench-shaped groove formed on the bottom surface of the anchor block body.
[0012] In some embodiments, the outer contour of the anchor block body is configured to have a structure with a cross-section that gradually decreases from bottom to top along the height direction of the anchor block body.
[0013] In some embodiments, the anchor block body is provided with at least one overflow hole extending from the top surface to the hollow structure.
[0014] In some embodiments, a hanging ring is provided at the center of the top of the anchor block body, and the hollow structure is arranged at the center of the bottom surface of the anchor block body.
[0015] Compared with the background technology introduction, the anchor block provided in the present application includes an anchor block body, and a hollow structure is formed at the bottom of the anchor block body. When it is applied to the underwater anchoring of the water photovoltaic system, since the bottom of the anchor block body is formed with a hollow structure, the hollow structure can increase the settlement depth of the anchor block in the soil layer on the one hand, and on the other hand, increase the contact area between the anchor block body and the bottom soil of the water area and improve the mechanical properties, thereby improving the horizontal bearing capacity of the anchor block. Therefore, compared with the traditional anchor block structure, the anchor block of the present application can greatly reduce the material used in the anchor block while ensuring the anchoring bearing capacity, thereby ultimately reducing the construction cost.

[0036] The core of this application is to provide an anchor block, an anchoring system and an on-water photovoltaic system to solve the problem of high construction cost of the anchor block in order to ensure the anchoring bearing capacity.
[0037] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0038] Reference Figure 1As shown, the anchoring system is the key foundation for ensuring the stable operation of the water surface photovoltaic power station. However, the anchoring system usually includes an anchor block 1 and a cable 2, wherein the anchor block 1 is mainly used to be sunk in the underwater soil layer of the water area, wherein one end of the cable 2 is connected to the anchor block 1, and the other end is connected to the photovoltaic array 3. By arranging multiple groups of anchor blocks 1 and cables 2, the various positions of the photovoltaic array 3 can be anchored and fixed underwater. However, the underwater soil layer in the water area is relatively complex, and the friction coefficient of the anchor block 1 relative to the underwater soil layer is not easy to determine. At present, in order to ensure the anchoring bearing capacity of the anchor block 1, the weight of the anchor block 1 is often increased, that is, the vertical bearing capacity is increased, thereby increasing the friction force of the anchor block 1 relative to the underwater soil layer. However, the problem brought about by this is that the material consumption of the anchor block 1 will be greatly increased, resulting in poor construction economy.
[0039] Based on this, refer to Figure 2-Figure 8 Combine Figure 1 As shown, the present application provides an anchor block 1 for underwater anchoring of a water-based photovoltaic system, comprising an anchor block body 10, with a hollow structure 11 formed at the bottom of the anchor block body 10. The hollow structure 11 is a hollow structure that is suspended from the bottom surface 101 of the anchor block body 10 toward the top surface 102 of the anchor block body 10 and does not penetrate the top surface 102 of the anchor block body 10.
[0040] When the anchor block 1 is applied to the underwater anchoring of the water photovoltaic system, since the bottom 101 of the anchor block body 10 is formed with a hollow structure 11, the hollow structure 11 can, on the one hand, increase the settlement depth of the anchor block 1 in the soil layer, and on the other hand, increase the contact area between the anchor block body 10 and the underwater soil of the water area and improve the mechanical properties, thereby improving the horizontal bearing capacity of the anchor block. Therefore, compared with the traditional anchor block structure, the anchor block of the present application can greatly reduce the material used for the anchor block while ensuring the anchoring bearing capacity, thereby ultimately reducing the construction cost.
[0041] It is worth mentioning that the anchor block 1 can be a concrete anchor block or an anchor block made of other materials, such as a metal block. In actual application, the configuration can be selected according to actual needs and no further specific restrictions are given here. Specifically, when the anchor block 1 is a concrete anchor block, it can be made by pouring concrete using a correspondingly designed casting mold; when the anchor block 1 is a metal block, it can be made by injection molding or machining by removing material.
[0042] In some specific embodiments, reference Figure 2-Figure 6As shown, the hollow structure 11 can be specifically configured as a concave cavity that extends from the bottom surface 101 of the anchor block body 10 toward the top surface 102 of the anchor block body 10. By designing the hollow structure 11 as a concave cavity, the fabrication of the hollow structure 11 is more convenient and easier to implement. The concave cavity can be a single, integral, recessed cavity or a hollow structure formed by a combination of multiple recesses. In actual applications, the configuration can be selected based on actual needs, and no further specific limitations are given here.
[0043] In a further embodiment, referring to Figure 2-Figure 5 The above-mentioned concave cavity can be specifically constructed into a structure with a cross-section that tapers from bottom to top along the height direction of the anchor block body 10. By designing into such a structural form, it is easier to remove the anchor block 1 from the mold during casting, because the mold core corresponding to the concave cavity position has a certain draft angle when it is removed. For example, the concave cavity can be constructed into a rectangular groove, wherein the side groove wall of the rectangular groove can be specifically designed to be Figure 5 The structure of the inclined surface shown can also be designed as Figure 2 and Figure 3 It should be noted that the specific structure of the concave cavity is not limited to being designed as a rectangular groove, but can also be designed as a circular groove, or a groove structure of other shapes, which is not further limited here.
[0044] Of course, it is understandable that the concave cavity is designed as the above-mentioned structure with a cross-section gradually shrinking from bottom to top along the height direction of the anchor block body 10 is only an example of the embodiment of the present application. In actual application, it can also be designed as Figure 6 The structure shown, i.e., the concave cavity is constructed with a uniform cross-section along the height of the anchor block body 10, with the side walls of the concave cavity arranged vertically. This structure provides a stronger lateral blocking force between the concave cavity and the soil layer trapped within it, but the casting mold is relatively large, requiring the core portion of the mold corresponding to the concave cavity to be designed to be detachable to facilitate demolding.
[0045] In some other specific embodiments, referring to Figure 7 and Figure 8 As shown, the hollow structure 11 can also be configured as a trench-shaped groove formed on the bottom surface 101 of the anchor block body 10. The cross-section of the trench-shaped groove can be an isosceles trapezoid, a U-shape, or a V-shape, and can be selected and set according to actual needs in actual applications. The advantage of designing this structural form is that during the sinking process of the anchor block 1, silt and water located at the hollow structure 11 can be quickly drained along the trench-shaped groove, making the sinking of the anchor block 1 more efficient.
[0046] In some more specific embodiments, reference Figure 8 As shown, the outer profile of the anchor block body 10 can be specifically configured to have a cross-sectional area that tapers from bottom to top along the height direction of the anchor block body 10. This structural design not only further reduces the material used for the anchor block, but also allows water to flow more easily over the surface of the anchor block body 10 with less resistance, thereby reducing the thrust of the water on the anchor block body 10.
[0047] In some other specific embodiments, referring to Figure 2-Figure 8 As shown, the anchor block body 10 may also be provided with at least one overflow hole 13 extending from the top surface to the hollow structure 11. This overflow hole 13 allows water and silt corresponding to the hollow structure 11 to overflow through the overflow hole 13 when the anchor block 1 is installed. This design accelerates the sinking speed of the anchor block 1 and, under the weight of the anchor block 1, ensures that the lower portion of the anchor block 1 can be fully embedded in the soil at the bottom of the water. The specific number and diameter of the overflow holes 13 can be selected based on actual needs and are not further specified here.
[0048] In some specific implementation schemes, a lifting ring 12 can be provided at the top center position of the above-mentioned anchor block body 10, which can be connected to the cable 2 connected to the photovoltaic array 3 through the lifting ring 12, making the connection and disassembly more convenient. For example, the corresponding end of the cable 2 can be designed with a shackle structure, which can realize convenient disassembly and assembly between the lifting ring 12 and the cable 2; in addition, the hollow structure 11 can be specifically selected to be arranged at the center position of the bottom surface 101 of the anchor block body 10. Because it is arranged at the center position, the force on each side wall of the anchor block body 10 corresponding to the hollow structure 11 is relatively balanced, and the force stability of the anchor block 1 is better.
[0049] On the other hand, the present application also provides an anchoring system. Figure 1 , comprising an anchor block 1 and a cable 2, one end of the cable 2 being connected to the anchor block 1, and the other end of the cable 2 being used to connect to the photovoltaic array 3. The anchor block 1 is any of the anchor blocks 1 described in the above-mentioned solutions. Since the above-mentioned anchor block 1 has the above-mentioned technical effects, the anchoring system including the anchor block 1 should also have the corresponding technical effects, which will not be described in detail here.
[0050] On the other hand, the present application also provides a water photovoltaic system, referring to Figure 1 , comprising a photovoltaic array 3 and an anchoring system for anchoring the photovoltaic array 3, wherein the anchoring system is the anchoring system described in the aforementioned solution. Since the aforementioned anchoring system has the aforementioned technical effects, the water-based photovoltaic system having this anchoring system should also have corresponding technical effects, which will not be described in detail here.
