[0036] The technical solution of the present application will be further explained below with reference to the accompanying drawings and through specific implementation methods.

[0037] Solar energy, a widely distributed green energy source, is one of the key energy sources for sustainable development in human society. Currently, the primary form of solar energy utilization is photovoltaic power generation, where photovoltaic modules absorb solar energy and convert it into electricity, providing energy for people's lives and production.

[0038] Example 1

[0039] This embodiment provides a floating photovoltaic power station. Built offshore, this station offers the advantages of unobstructed access and extended sunshine hours, significantly increasing power generation and addressing the increasing shortage of land resources. The floating photovoltaic power station comprises a floating array and anchor blocks. The floating array floats on the water surface, carrying photovoltaic modules. The anchor blocks are submerged in the water, connected to the anchor blocks by cables. The anchor blocks are a crucial component of the floating photovoltaic power station, securing the station and maintaining its stability.

[0040] However, in some scenarios, the underwater terrain is complex, the underwater soil is soft, and the slope is large. The anchor blocks may slip after sinking to the bottom of the water, resulting in the inability to fix the floating photovoltaic power station and affecting the stability of the floating photovoltaic power station.

[0041] To solve the above problems, the present embodiment provides an anti-slip anchor block, as shown in Figures 1 and 2, the anti-slip anchor block includes an anchor block body 1 and a fixing component 2, the fixing component 2 is fixedly arranged on the bottom surface of the anchor block body 1, and the fixing component 2 includes multiple anti-skid plates, which are configured to be inserted into the sand on the bottom of the water.

[0042] The main weight of the anti-slip anchor block is provided by the anchor block body 1, so that the anti-slip anchor block can sink in the water and the anti-slip plate can be inserted into the sand at the bottom of the water, providing additional lateral bearing capacity for the anti-slip anchor block, and multiple anti-slip plates can further increase the lateral bearing capacity and ensure the stability of the floating photovoltaic power station.

[0043] In this embodiment, the multiple anti-skid plates include a plurality of first anti-skid plates 21 arranged at intervals along a first direction (X direction in the figure) and a plurality of second anti-skid plates 22 arranged along a second direction (Y direction in the figure). The multiple first anti-skid plates 21 and the multiple second anti-skid plates 22 are cross-arranged, and the first direction and the second direction are arranged at an angle.

[0044] It's understandable that when the anti-skid plate is perpendicular to the traction force exerted by the anti-skid anchor on the floating array, the anti-skid plate's anti-skid effect is the best. However, when the anti-skid plate is parallel to the traction force exerted by the anti-skid anchor on the floating array, the anti-skid plate has little anti-skid effect. Therefore, the multiple first anti-skid plates 21 and the multiple second anti-skid plates 22 are arranged at an angle to ensure that the anti-skid anchor blocks maintain their anti-skid effect regardless of the angle at which they are inserted into the soil underwater. Furthermore, the first direction and the second direction are perpendicular.

[0045] In this embodiment, a plurality of first anti-skid plates 21 abut against the bottom surface of the anchor block body 1, and a plurality of second anti-skid plates 22 are spaced apart from the bottom surface of the anchor block body 1. Structurally, the width of the first anti-skid plates 21 is greater than the width of the second anti-skid plates 22. The width of the first anti-skid plates 21 is the vertical dimension, while the width of the second anti-skid plates 22 is the vertical dimension. The abutment of the first anti-skid plates 21 against the bottom surface of the anchor block body 1 improves the stability between the fixing assembly 2 and the anchor block body 1. This structure also connects the spaces separated by the second anti-skid plates 22. When excessive sand and soil accumulate in a certain space, the sand and soil will flow into other spaces through the gap between the second anti-skid plates 22 and the anchor block body 1, allowing the sand, water, and gas at the bottom to be discharged, ensuring that the anti-slip anchor block can settle more quickly and increase its insertion depth into the soil.

[0046] Furthermore, the first anti-slip plates 21 are provided with a plurality of communication holes 211 spaced apart along the second direction, and there is at least one communication hole 211 between every two adjacent second anti-slip plates 22. The communication holes 211 connect the spaces separated by the first anti-slip plates 21, further improving the fluidity of the sand at the bottom of the anti-slip anchor block.

[0047] In this embodiment, the anti-slip anchor block further includes a mooring ring 3, which is fixedly mounted on the top surface of the anchor block body 1, with the axial direction of the mooring ring 3 extending along the second direction. The mooring ring 3 is used to connect a cable. Furthermore, typically, the axial direction of the mooring ring 3 is perpendicular to the direction of force applied by the cable. In other words, when the anti-slip anchor block exerts a pulling force on the floating array, the first anti-slip plate 21 of the fixing assembly 2 plays a primary role in preventing slippage. In this case, the wider size of the first anti-slip plate 21 enhances the anti-slip effect and ensures sufficient strength.

[0048] Furthermore, the widths of the multiple first anti-skid plates 21 increase or decrease successively along the first direction, or the widths of the multiple first anti-skid plates 21 gradually increase or decrease from outside to inside along the first direction. The widths of the multiple first anti-skid plates 21 change successively. When the anti-slip anchor block sinks, the multiple first anti-skid plates 21 are inserted into the soil successively, thereby reducing the resistance of the anti-slip anchor block to sinking.

[0049] As shown in Figure 1 , the anchor block body 1 includes a load member 11 and a base 12, which are fixedly connected to each other. The primary weight of the anchor block body 1 is provided by the load member 11, while the base 12 supports the load member 11. Specifically, the fixed connection between the base 12 and the load member 11 is achieved via a fixing rope, with both ends of the fixing rope fixedly connected to the base 12, thus securing the load member 11 to the base 12.

[0050] In this embodiment, the anti-slip anchor block also includes a lifting ring 4 and an anti-rotation pull ring 5, which are both fixedly arranged on the top surface of the anchor block body 1, wherein the height of the lifting ring 4 protruding from the anchor block body 1 is greater than the height of the mooring ring 3 protruding from the anchor block body 1, which is convenient for lifting large equipment; the mooring ring 3 is relatively low in height, which is conducive to reducing the height of the force point and reducing the eccentricity of the anchor block; the anti-rotation pull ring 5 is arranged at the corners of the anchor block body 1, and can provide external force through another cable to prevent the anchor block body 1 from rotating during the lowering process.

[0051] In the prior art, in order to ensure the strength of the anchor block body 1, it is necessary to extend the lifting ring 4, the mooring ring 3 and the anti-rotation pull ring 5 into the steel cage and tie them in place, and then form the load-bearing member 11 by pouring concrete into the steel cage to make the steel bars stronger and the anchor block body 1 has sufficient weight.

[0052] In this embodiment, the anti-slip anchor block also includes a first fixing member, and the fixing assembly 2 also includes a fixing frame. Multiple anti-slip plates are fixedly disposed within the fixing frame, and the fixing frame and the load member 11 are fixedly connected via the first fixing member. Specifically, the fixing frame is connected to a lug plate 14. The first fixing member passes through the lug plate 14 and is inserted into the load member 11 to secure the load member 11 to the fixing frame. In this embodiment, the first fixing member is an expansion bolt to ensure a reliable connection between the first fixing member and the load member 11.

[0053] As shown in FIG. 2 , the fixing frame is formed by two outermost first anti-slide plates 21 and two outermost second anti-slide plates 22 .

[0054] Example 2

[0055] This embodiment is based on the first embodiment, and improves the connection method between the fixing frame and the anchor block body 1.

[0056] As shown in Figures 3 and 4, in this embodiment, the fixing frame and the base 12 are fixedly connected by a first fixing member. The fixing frame and the base 12 are both provided with corresponding connecting plates 6. The first fixing member is a bolt that passes through the connecting plates 6 of the fixing frame and the connecting plates 6 of the base 12 to securely connect the fixing frame and the base 12.

[0057] Example 3

[0058] This embodiment is based on the first and second embodiments, and improves the connection method between the fixing frame and the anchor block body 1.

[0059] As shown in Figures 5 to 7 , the anti-slip anchor block also includes a second fixing member 15. One end of the second fixing member 15 is fixedly disposed within the load member 11, and the other end of the second fixing member 15 is fixedly connected to the fixing assembly 2. The second fixing member 15 and the load member 11 are integrally structured. The connection between the second fixing member 15 and the fixing assembly 2 ensures a reliable connection between the fixing assembly 2 and the anchor block body 1.

[0060] Specifically, when manufacturing the load member 11, the second fixing member 15 is first implanted at the bottom of the steel cage and inserted deep into the cage. Then, during concrete pouring, the end of the second fixing member 15 is ensured to protrude from the concrete. Furthermore, the second fixing member 15 is a steel bar. When the steel bar is implanted at the bottom of the cage, the steel bar can be wrapped around the cage to increase structural strength.

[0061] In this embodiment, the fixing assembly 2 includes a connecting platform 23 corresponding to the second fixing member 15. The connecting platform 23 is arranged at the intersection of the first anti-slip plate 21 and the second anti-slip plate 22 to improve the strength. The second fixing member 15 is welded and fixed to the connecting platform 23. The connecting platform 23 has a large area, which facilitates the welding operation with the second fixing member 15.

[0062] Example 4

[0063] This embodiment improves the connection method between the fixing frame and the anchor block body 1 on the basis of the first, second and third embodiments.

[0064] As shown in Figures 8 and 9, the anti-slip anchor block also includes a fixing tube 7 and a limiting pin 8. The fixing tube 7 is passed through the drainage hole 13. The first end of the fixing tube 7 extends out of the bottom surface of the anchor block body 1 and is fixedly connected to the fixing assembly 2. The second end of the fixing tube 7 extends out of the top surface of the anchor block body 1. The limiting pin 8 is passed through the second end of the fixing tube 7 and abuts against the top surface of the anchor block body 1.

[0065] The first end of the fixing tube 7 is fixedly connected to the fixing assembly 2, and the second end of the fixing tube 7 is inserted with a limiting pin 8 for limiting, so that the fixing tube 7 can connect the anchor block body 1 with the fixing assembly 2, and at the same time the fixing tube 7 will not affect the air permeability of the drainage hole 13.

[0066] The number and position of the drainage holes 13 can be designed according to the volume of the anti-slip anchor block, and the fixed pipe 7 needs to be welded and fixed to the anti-slip plate of the fixed component 2, so the setting of the anti-slip plate can be adjusted according to the position of the fixed pipe 7.

[0067] It is worth noting that the connection method between the fixing frame and the anchor block body 1 is not limited to being implemented alone. The fixing solutions of Example 1, Example 2, Example 3 and Example 4 can be combined and implemented, or other existing fixing methods can be used, which will not be repeated here.

[0068] The above content is only a preferred embodiment of the present application. For ordinary technicians in this field, according to the concept of the present application, there may be changes in the specific implementation method and application scope. The content of this specification should not be understood as limiting the present application.
