Description

Technical Field

[0001] This utility model relates to a floating offshore wind power anchor chain auxiliary construction device, belonging to the field of floating offshore wind power technology. Background Technology

[0002] Floating offshore wind power systems are a technology that uses floating structures to support wind turbines to generate electricity at sea. The core of the technology lies in its floating structure, which can adapt to different water depths and sea conditions, enabling the wind power generation system to be deployed in a wider range of sea areas.

[0003] Floating offshore wind power systems use a floating platform as the base for the wind turbine, while the anchor chain is a crucial component connecting the floating platform to the seabed, serving for positioning and fixation. See Chinese Patent Publication No. CN206707930U.

[0004] When it is necessary to salvage the anchor chain, because the anchor chain is in the ocean water, it will be covered with too much debris such as seaweed. When the anchor chain is directly salvaged onto the floating body, the manual cleaning of the excessive debris on the outside of the anchor chain is very arduous. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a floating offshore wind power anchor chain auxiliary construction device.

[0006] This utility model is achieved through the following technical solution.

The other end of the anchor chain passes through the floating platform, and the floating platform is provided with a chain outlet for the anchor chain to pass through and be lowered or retracted; the floating platform at the chain outlet is fixed with a connecting base plate, and a cleaning pad made of elastic material is fixed on the connecting base plate.

[0008] The floating platform has floating plates fixed to its outer perimeter.

[0009] The floating platform is fixed with a fixed base, and a tower is fixed on the fixed base. The tower is formed into the tower structure of a wind turbine. The hub of the wind turbine is installed on the tower by a fixed rod, and rotatable blades are installed on the hub.

[0010] It also includes a protective shell that covers and protects the motor, movable shaft, and chain carrier, with ventilation holes for air circulation and heat dissipation.

[0011] A gravity anchor is fixedly connected to the bottom of the anchor chain, and the top of the gravity anchor is fixedly connected to the anchor chain. The bottom of the gravity anchor is concave upward to form a suffix. A first insert rod is slidably installed at the bottom of the gravity anchor. A second insert rod is slidably mounted on the side of the gravity anchor through a channel. Multiple channels and second insert rods are arranged in a circumferential array. The second insert rod is fixedly connected to the inner side of the suffix of the gravity anchor through a first spring. A waterproof cloth is fixed to the gravity anchor at the opening of the channel, and the second insert rod can extend outward through the waterproof cloth. A limit plate is fixed to the end of the second insert rod near the suffix.

[0012] It also includes support components installed on a floating platform to support the tower, the support components being multiple sets distributed in a circumferential array.

[0013] The support assembly includes a connecting seat that is fixedly connected to the floating platform, and a second fixing plate is fixed on the connecting seat; The support leg is hinged to the second fixed plate, and the top of the support leg is hinged to the first fixed plate, which is fixed to the outside of the tower; torsion springs that provide rotational force are installed at both hinge points of the support leg.

An elastic rope is fixedly connected to the outside of the wiping pad. The middle part of the elastic rope is fixed to the outside of the wiping pad, and the two ends of the elastic rope are fixed to the movable shaft and wound up.

[0016] The beneficial effects of this utility model are as follows: the cleaning pads made of elastic rubber are spaced apart on the connecting bottom plate. When the anchor chain is wound up and lifted by the rotating chain seat, the debris attached to the anchor chain in the seawater is partially cleaned by the cleaning pads as it passes through the spaced cleaning pads. This solves the problem that there is too much debris on the float when the anchor chain is directly retrieved, which leads to high manual cleaning intensity. Attached Figure Description

Detailed Implementation

[0018] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0019] like Figures 1 to 6 As shown.

[0020] This application discloses a floating offshore wind power anchor chain auxiliary construction device, comprising: A floating platform 1, which floats on the sea surface during use, provides force to the whole. A fixed base 11 is fixed on the floating platform 1, and a tower 12 is fixed on the fixed base 11. The tower 12 constitutes the tower structure of the wind turbine. The hub 14 of the wind turbine is installed on the tower 12 through a fixed rod 13. Rotatable blades 15 are installed on the hub 14. The blades 15 are rotated by the sea breeze. The rotating blades 15 drive the power generation components inside the hub 14 to generate electricity. This is the prior art and will not be described in detail here.

[0021] The floating platform 1 has a floating plate 7 fixed to its outer periphery on its side. The floating plate 7 is counterweighted to keep the floating platform 1 stable and prevent collisions.

[0022] A motor 17 is fixed on the floating platform 1. A movable shaft 18 is fixed to the output shaft end of the motor 17. A chain carrier 19 is fixed to the movable shaft 18. An anchor chain 111 is fixedly installed on the chain carrier 19. One end of the anchor chain 111 is wound around the chain carrier 19. After the chain carrier 19 rotates, the wound anchor chain 111 can be unfolded and lowered. The other end of the anchor chain 111 passes through the floating platform 1. The floating platform 1 is provided with a chain outlet 110 for the anchor chain 111 to pass through and lower or retract. A connecting base plate 5 is fixed to the floating platform 1 at the chain outlet 110. A cleaning pad 51 made of elastic material is fixed on the connecting base plate 5.

[0023] The cleaning pads 51, made of elastic rubber, are spaced apart on the connecting base plate 5. When the anchor chain 111 is wound up and lifted by the rotating chain seat 19, the debris attached to the anchor chain 111 in the seawater is partially cleaned by the cleaning pads 51 as it passes through the spaced cleaning pads 51. This solves the problem of excessive debris on the float when the anchor chain is directly retrieved, which leads to high manual cleaning intensity.

[0024] It also includes a protective shell 6 that covers and protects the motor 17, the movable shaft 18, and the chain carrier 19. The protective shell 6 is provided with ventilation holes 61 for ventilation and heat dissipation.

[0025] A gravity anchor 112 is fixedly connected to the bottom of the anchor chain 111, and the top of the gravity anchor 112 is fixedly connected to the anchor chain 111. The bottom of the gravity anchor 112 is concave upward to form a suffix. A first insert rod 2 is slidably installed at the bottom of the gravity anchor 112 and can be inserted into the seabed sediment. A second insert rod 22 is slidably mounted on the side of the gravity anchor 112 through a channel 21. Multiple channels 21 and second insert rods 22 are arranged in a circumferential array. The second insert rod 22 is fixedly connected to the inner side of the suffix of the gravity anchor 112 through a first spring 24. A waterproof cloth 25 is fixed to the gravity anchor 112 at the opening of the channel 21. The second insert rod 22 can extend outward through the waterproof cloth 25. When the second insert rod 22 extends, the first spring 24 is compressed. A limiting plate 23 is fixed to the end of the second insert rod 22 near the suffix to limit the second insert rod 22 and prevent it from completely falling out of the channel 21.

[0026] After the anchor chain 111 is unfurled and lowered, bringing the gravity anchor 112 into contact with the seabed sediment, the first insertion rod 2 is inserted into the seabed sediment. As the first insertion rod 2 slides into the obstruction hole of the gravity anchor 112, the first insertion rod 2 inside the obstruction hole is pushed out to the side of the gravity anchor 112 by the pressure of the compressed air inside the gravity anchor 112, and the first spring 24 is compressed. When the anchor chain 111 is retracted and the gravity anchor 112 is lifted, the first insertion rod 2 slides out of the obstruction hole of the gravity anchor 112, and the compressed first spring 24 pulls the first insertion rod 2 inward into the gravity anchor 112.

[0027] It also includes a support assembly installed on the floating platform 1 and supporting the tower 12, wherein the support assembly is a plurality of sets distributed in a circumferential array.

[0028] The support component includes a connecting seat 33 fixedly connected to the floating platform 1, and a second fixing plate 32 fixed on the connecting seat 33; The support leg 31 is hinged to the second fixing plate 32, and the top of the support leg 31 is hinged to the first fixing plate 3, which is fixed to the outside of the tower 12; torsion springs that provide rotational force are installed at both hinge points of the support leg 31.

[0029] A wiping component is fitted over the outer area of ​​the tower 12 between the support assembly and the fixed base 11, and the wiping component performs wiping and cleaning on the outside of the tower 12.

[0030] The wiping assembly includes a wiping pad 41 that is fitted over the outside of the tower 12. A second spring 42 is fixedly connected to the bottom of the wiping pad 41, and the bottom of the second spring 42 is fixedly connected to the fixed base 11. An elastic rope 4 is fixedly connected to the outside of the wiping pad 41. The middle part of the elastic rope 4 is fixed to the outside of the wiping pad 41, and the two ends of the elastic rope 4 are fixed to the movable shaft 18 and wound up. The two ends of the elastic rope 4 can slide through the protective shell 6 before being wound up with the movable shaft 18. When the movable shaft 18 rotates and wound up the elastic rope 4, the wiping pad 41 pulls down and wipes the outside of the tower 12 downwards. At this time, the second spring 42 is compressed. When the movable shaft 18 rotates and unfolds the elastic rope 4, the compressed second spring 42 provides elastic force, causing the wiping pad 41 to pull down and wipe the outside of the tower 12 upwards.
