[0031] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0032] The wind speed is higher and more stable at high altitudes, far away from interference from ground buildings. To utilize the wind energy resources at high altitudes, people have created floating wind turbines. In order to transmit the power of floating wind turbines to the ground, cables are needed to connect the floating wind turbines to the ground equipment. However, the wind direction at high altitudes changes frequently, which will cause the cables at high altitudes to change the direction of force as the wind direction changes. The current cables are fixedly connected to the anchors and cannot rotate relative to each other, and cannot adapt to the changing wind direction, making the cables easily damaged.

[0033] Based on this, please refer to Figure 1 , Figure 2 and Figure 3 The anchoring device 1000 provided in the embodiment of the utility model can solve the above-mentioned technical problems. The anchoring device 1000 can be applied to various devices for connecting high-altitude cables, such as a cable 2000 assembly. Both the anchoring device 1000 and the cable 2000 assembly can make the cable 2000 rotate with the wind direction, thereby improving the service life of the cable 2000.

[0034] Figure 1 A schematic diagram of an anchor 100 provided in an embodiment of the present utility model; Figure 2 A schematic diagram of a cross section of an anchor 100A-A provided in an embodiment of the present utility model; Figure 3 FIG. 2 is a schematic diagram of an intermediate piece 200 provided with a cable 2000 in an embodiment of the present invention, as shown in FIG. Figure 1 , Figure 2 and Figure 3 As shown, the anchor device 1000 in this embodiment includes an anchor 100 and an intermediate member 200, wherein the intermediate member 200 is rotatably connected to the anchor 100, and the intermediate member 200 is used to fix the cable. The cable and the anchor 100 are connected by the intermediate member 200, and the intermediate member 200 is rotatably connected to the anchor 100, thereby driving the cable to rotate relative to the anchor 100 to adapt to the changing wind direction at high altitude and increase the adaptability life of the cable.

[0035] In order to compress the middle piece 200 and prevent the middle piece 200 with the cable fixed thereon from being separated from the anchor 100, the anchor 100 in this embodiment includes a mounting seat 110 and a top cover 120. The middle piece 200 is assembled between the mounting seat 110 and the top cover 120. The middle piece 200 is rotatably connected to the mounting seat 110 around the axis 111 of the mounting seat. The top cover 120 is used to limit the middle piece 200 from being separated from the mounting seat 110 along the axial direction of the mounting seat 110. Specifically, in order to realize the rotation connection between the middle piece 200 and the mounting seat 110, the anchor 100 in this embodiment also includes a sleeve 130. The mounting seat 110 has a mounting hole 112. The mounting seat 110 is used to be connected to the mounting plane. The sleeve 130 is sleeved in the mounting hole 112. The middle piece 200 is located in the sleeve 130. The sleeve 130 can rotate around the axis of the mounting hole 112.

[0036] The middle piece 200 in this embodiment has a through hole 210, and the cable is connected and fixed to the middle piece 200 through the through hole 210. The anchor 100 has a mounting hole 112, and the middle piece 200 is connected to the anchor 100 through the mounting hole 112, and the middle piece 200 can rotate in the mounting hole 112; the anchor 100 is used to fix the cable 2000 to the mounting plane. The cable 2000 and the anchor 100 are connected by the middle piece 200, and the anchor 100 has a mounting hole 112, and the middle piece 200 is connected to the anchor 100 through the mounting hole 112, and the middle piece 200 can rotate in the mounting hole 112, thereby driving the cable 2000 to rotate in the mounting hole 112 to adapt to the changing wind direction at high altitude and increase the adaptability life of the cable 2000. Avoid the cable 2000 from being entangled due to the rotation of the wind direction, or the cable 2000 is always stressed on one side at a certain place, which affects the normal use of the cable 2000.

[0037] Since the sleeve 130 is only sleeved in the mounting hole 112, and the middle piece 200 is connected with the sleeve 130, when the wind direction at high altitude changes, the middle piece 200 can be rotated, and the middle piece 200 drives the sleeve 130 to rotate relative to the axis of the mounting hole 112, thereby causing the cable 2000 fixed on the middle piece 200 to rotate accordingly to adapt to the changing wind direction at high altitude. Since the middle piece 200 with the cable 2000 needs to be installed in the mounting hole 112 of the mounting seat 110 of the anchor 100 during installation, the shape and size of the mounting hole 112 sleeved with the sleeve 130 are the same as the shape and size of the middle piece 200. The middle piece 200 in this embodiment is cylindrical, so the cross-sectional shape of the mounting hole 112 is also circular, and the shape and size of the sleeve 130 match the shape and size of the middle piece 200. Of course, the middle piece 200 may also be in other shapes such as a cuboid or a cube, and correspondingly, the shapes of the bushing 130 and the mounting hole 112 will also change accordingly.

[0038] See also Figure 1In order to facilitate the placement of the middle piece 200 with the cable 2000 into the mounting hole 112, the top cover 120 in this embodiment includes two pressing caps 121, which are detachably connected and detachably connected to the mounting seat 110. Of course, the pressing caps 121 can be standard or non-standard, as long as they can facilitate the placement of the middle piece 200 into the mounting hole 112 and can achieve a pressing effect on the middle piece 200 to prevent the middle piece 200 from being separated from the mounting seat 110. The specific structure and shape of the pressing caps 121 are not limited here. Specifically, the two pressing caps 121 in the present embodiment are semicircular pressing caps 121, and the semicircular pressing caps 121 and the mounting seat 110, and the two semicircular pressing caps 121 are connected by bolts and nuts. When the middle piece 200 with the cable 2000 needs to be installed in the mounting hole 112 of the mounting seat 110, the two semicircular pressing caps 121 are disconnected from the mounting seat 110, and then the nuts connecting the two semicircular pressing caps 121 are loosened, the two semicircular pressing caps 121 are separated, and the middle piece 200 with the cable 2000 is installed, and then the two semicircular pressing caps 121 are fixedly connected. In order to prevent the two semicircular pressing caps 121 from separating due to loose connection during operation and the two semicircular pressing caps 121 from separating from the mounting seat 110, the nuts in the present embodiment are anti-loosening nuts. In order to achieve compression and fixation of the middle piece 200, the size of the circular hole formed by the two semicircular pressing caps 121 is smaller than the size of the middle piece 200, so as to compress and fix the middle piece 200 and prevent the cable 2000 from applying an upward force to drive the middle piece 200 to move upward.

[0039] Please continue reading Figure 1 , and combined with Figure 2 In order to strengthen the fixed connection between the mounting seat 110 of the anchor 100 and the ground to bear a higher load, the mounting seat 110 in this embodiment is a flange seat. The flange seat has multiple connection holes, and multiple bolts and other fasteners can be used to fix the flange seat to the mounting plane. Multiple bolts and other fasteners are evenly stressed to bear more loads. In addition, the flange manufacturing cost is relatively low and the assembly is simple.

[0040] In order to better fix the cable 2000 and facilitate the cable 2000 to rotate with the change of wind direction, the middle piece 200 in this embodiment is cylindrical, and the bottom diameter of the middle piece 200 is larger than the outer diameter of the cable 2000.

[0041] To protect the suspended cable 2000 and reduce the tension it experiences during operation, the suspended fan should be fixed by a tether, which bears the tension and is always in a tensioned state. Therefore, the tether length of the suspended fan should always be less than the length of the cable 2000. To further reduce the tension on the cable 2000, please refer to Figure 3, the axis 211 of the through hole in this embodiment is set at an angle to the rotation center line 220 of the middle piece 200. Therefore, the cable 2000 is connected to the installation plane at an angle through the middle piece 200, so that the cable 2000 can present a curved shape in the air, thereby reducing the tension borne by the cable 2000. The angle between the axis 211 of the through hole and the installation plane can be determined according to the local wind force and the wind direction in most cases, and the specific inclination direction and angle of the inclination angle are not limited here.

[0042] This embodiment also provides a cable assembly, including a cable 2000 and the anchoring device 1000 in any of the above embodiments.

[0043] In order to keep the cable 2000 stable at high altitude and adapt to wind direction, please refer to Figure 4 The cable 2000 in this embodiment includes a plurality of cores 2100, a filler strip 2200 and an armor layer 2300. The plurality of cores 2100 are arranged in parallel, and the armor layer 2300 wraps the plurality of cores 2100. The gaps between the plurality of cores 2100 and the gaps between the plurality of cores 2100 and the armor layer 2300 are both provided with filler strips 2200. In order to increase the structural strength and fatigue resistance of the cable 2000, in this embodiment, a reinforcing rib 2400 may also be provided in the filler strip 2200. The parallel arrangement of the plurality of cores 2100 may make the cross-sectional shape of the cable 2000 streamlined or elliptical, thereby reducing the area of ​​the windward side of the cable 2000 to maintain the stability of the cable 2000 in the air. The cross-sectional shape of the cable 2000 in this embodiment is elliptical, and the number of the cores 2100 is three. In order to maintain the stability of the cable 2000 in the air, in this embodiment, the cable 2000 is driven to rotate by rotating the intermediate piece 200, so that the area of ​​the windward side of the cable 2000 is always at a minimum.

[0044] The underground cable 2000 or submarine cable 2000 for outputting power from a conventional wind turbine usually uses copper or aluminum conductors and steel wire armoring, which is heavy in weight, increasing the tension on the cable 2000 at the high-altitude wind turbine. In order to reduce the weight of the cable 2000, the multi-strand core 2100 in this embodiment is made of carbon fiber conductor material, and the armor layer 2300 is made of non-metallic material. The carbon fiber conductor has a low density, high strength, and is fatigue-resistant. It can reduce the weight of the cable 2000 and reduce the tension on the cable 2000 while ensuring the strength of the cable 2000. The weight of non-metal is lighter than that of metal, so the use of non-metallic armor can reduce the overall weight of the cable 2000. Of course, in order to ensure the structural strength of the cable 2000, the non-metallic armor layer 2300 in this embodiment uses materials such as aramid and carbon fiber with low density and high strength.

[0045] This embodiment also provides a cable system, including the cable assembly, cable clamp, fixing device of the anchoring device 1000 and other structural parts in any of the above embodiments, which have the same functions as the above cable assembly and are not repeated here.

[0046] According to an anchoring device 1000 provided in this embodiment, its working principle is as follows:

[0047] When the wind direction changes in the air, the intermediate piece 200 is rotated to drive the cable 2000 to rotate, so that the cable 2000 can adapt to the change of wind direction, and avoid the cable 2000 from getting tangled or the cable 2000 being stressed on one side, which affects the normal use of the cable 2000. In order to improve the stability of the cable 2000 in the air, the cross-sectional shape of the cable 2000 is designed to be streamlined or elliptical, so that the area of ​​the windward side of the cable 2000 is reduced to maintain the stability of the cable 2000 in the air.

[0048] In summary, the anchor device 1000 includes an anchor 100 and an intermediate piece 200, wherein the intermediate piece 200 is rotatably connected to the anchor 100, and the intermediate piece 200 is used to fix the cable. The cable and the anchor 100 are connected by the intermediate piece 200, and the intermediate piece 200 is rotatably connected to the anchor 100, thereby driving the cable to rotate relative to the anchor 100 to adapt to the changing wind direction at high altitude, avoid cable entanglement, or a certain part of the cable is always stressed on one side, which affects the normal use of the cable, and increases the adaptability life of the cable.

[0049] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
