Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power, and in particular to an offshore wind power device with a floating foundation. Background Art

[0002] Wind power generation is the fastest growing green energy technology in the world. While the construction of onshore wind farms is developing rapidly, people have noticed some limitations on the use of onshore wind energy, such as large land area and noise pollution. Due to the abundant offshore wind energy resources and the feasibility of current technology, the ocean will become a rapidly developing wind power market.

[0003] The patent with publication number CN116620514A discloses a method for batch assembly and transportation of floating offshore wind power equipment support structure in an embodiment, including assembling a floating wind power support structure; transporting the assembled floating wind power support structure in the sea. The floating wind power support structure includes a support column; a cross brace, which is arranged and connected between two adjacent support columns; and a fixed structure, which is used to connect the cross brace and the support column. The support column includes a first support column, a second support column and a third support column, and a first bearing positioning part is arranged on the circumference of each support column, and the first bearing positioning part includes a first bearing plate of the first bearing positioning part and at least two first plates with a certain gap distance and parallel to each other, and a through hole penetrating the thickness of the plate is arranged in the middle area of ​​the plate surface of the first plate, and the through holes of each first plate are arranged coaxially, and the end of the first plate is fixed to the first plate surface of the first bearing plate of the first bearing positioning part, and the first bearing plate of the first bearing positioning part is fixed to the circumference of the support column, and the support column is a hollow rolled round steel pipe. The floating wind power support structure is not assembled in the shipyard where the land is already scarce, which avoids the phenomenon of large-scale equipment occupying the shipyard area, and can optimize the shipyard use plan. At present, there are not many shipyards that can undertake the assembly of large-scale equipment such as floating wind power support structures, so the current floating wind power support structure assembly needs to be carried out in certain shipyards of certain sizes. The applicable shipyard may be very far away from the sea area where the equipment is designated to be used, and the cost and difficulty of loading and unloading and transporting such assembled large-scale integrated equipment will be significantly increased. The assembly of the present invention is carried out in the sea area, the assembly site selection requirements are low, and it is more flexible and mobile. The ability to form new assembly areas can be achieved through the use of the equipment in a certain way, and therefore the ability to assemble and move the equipment nearby the designated sea area. Large-scale use can greatly reduce the cost and difficulty of transporting large equipment.

[0004] The above technical solution transports accessories by ship and performs temporary assembly of supporting structures at the location where offshore wind power equipment is required to be built. Compared with the assembly of accessories in the factory, temporary assembly in the sea area still requires the assembly of supporting structures on ships with smaller space than the factory, which makes the assembly of supporting structures more inconvenient. Secondly, there are fewer assembly equipment in the sea area. Although the assembly of supporting structures is relatively simple, it is cumbersome. The temporary assembly of supporting structures before the deployment of wind power equipment will greatly delay the deployment efficiency of wind power equipment. The large-scale laying of supporting structures in the sea area requires workers to continuously connect accessory structures. The temporary labor intensity of workers deploying equipment is high. Therefore, this deployment method is relatively cumbersome in actual use. Therefore, there is an urgent need for an offshore wind power equipment with a floating foundation to solve the above-mentioned problems. Summary of the invention

The driving mechanism 5 includes a bottom plate 501 placed against the lower side of the bottom box 101. A buckle plate 502 is fixedly connected to the outer side of the upper surface of the bottom plate 501.

The center of the water wheel 506 is flush with the floating ring mechanism 3.

[0031] The working principle of the present invention is as follows: When the equipment is deployed at sea, the floating ring mechanism 3, the wind power mechanism 4 and the driving mechanism 5 are assembled on the boxed mechanism 1 later. Therefore, the boxed mechanism 1, the floating ring mechanism 3, the wind power mechanism 4 and the driving mechanism 5 can be transported separately during transportation. In this way, the volume of the equipment during transportation is small, and the protection during transportation can be effectively improved, which is convenient for sea transportation of the equipment.

[0032] After the equipment is transported to the deployment site, the semicircular ring assembly of the floating ring mechanism 3 is inserted into the buckle ring 109 and then screwed together, and the wind power mechanism 4 is installed on the boxed mechanism 1. It is selected according to needs whether to assemble the drive mechanism 5 by clamping the buckle plate 502 and the bottom box 101. By integrally assembling the boxed mechanism 1, the floating ring mechanism 3, the wind power mechanism 4 and the drive mechanism 5, the workload of docking for temporary assembly of the equipment is reduced, thereby improving the deployment efficiency of the equipment.

[0033] After the floating ring mechanism 3 is connected to the bottom box 101 through the connecting assembly, the external inflation device is connected to the air pipe 305 to inflate the float bag 304 and protrude from the bag mouth 303 outside the ring shell 301, thereby providing buoyancy for the equipment. After the equipment enters the water, the equipment can float on the water surface. After the inflation of the float bag 304 is completed, the lower end of the second air duct 406 is connected to the air pipe 305. In this way, when the wind power equipment 403 absorbs air through the air guide chamber 404, part of the air flow can be poured into the float bag 304 through the first air duct 405, the second air duct 406 and the air pipe 305. In this way, the filling degree of the float bag 304 is maintained with the help of offshore wind power, thereby extending the service life of the equipment.

[0034] The buckle column 108 on the connecting component is movably connected to the bottom box 101. When there are wind and waves on the sea, the floating ring mechanism 3 will tilt along with the waves due to the floating bag 304 thereon. Through the existence of the connecting component, the boxed mechanism 1, the wind power mechanism 4 and the driving mechanism 5 can remain stable under the action of gravity, reduce the tilt angle and frequency, and improve the working stability of the equipment.

[0035] The bottom box 101 and the box cover 105 are connected by a multi-stage telescopic column 104. The distance between the bottom box 101 and the box cover 105 can be changed by the extension and retraction of the multi-stage telescopic column 104, thereby changing the height of the wind power structure 4 from the sea surface, improving the adjustability of the equipment and the flexibility of the equipment.

[0036] Assemble the driving mechanism 5 at the desired time. With the driving mechanism 5, the starting motor 504 can drive the water wheel 506 to rotate through the linkage 507, so that the lower side of the water wheel 506 can wade through water and paddle water during its rotation. By adjusting the rotation direction of the water wheels 506 on both sides, the boxed mechanism 1 can be moved on the water surface, thereby improving the mobility of the equipment and the maneuverability of the equipment.

[0037] Through the extension of the multi-stage telescopic column 104 and the active hinge between the inner support mechanism 2 and the base box 101 and the box cover 105, when the base box 101 and the box cover 105 are separated, the two connecting rod assemblies of the support assembly will deflect around the mutual hinge of their receiving balls 202, and the two connecting rod assemblies will gradually become vertical, through the support plate 204 that is movably hinged on the arm plate 201, after the arm plate 201 is vertical, the support plate 204 will flip into a horizontal state driven by the gravity of the counterweight ball 208, forming a connection between the support plates 204 between the arm plates 201, thereby making the support assemblies support each other, automatically improving the internal strength of the box-mounted mechanism 1, and improving the supporting strength of the equipment.

[0038] The bottom box 101 and the box cover 105 are movably connected by a multi-stage telescopic column 104, and the interior is supported by an internal support mechanism 2. The internal support mechanism 2 has many accessories, and the outer sides of the bottom box 101 and the box cover 105 are enclosed by a retractable waterproof belt 110, thereby effectively preventing seawater from corroding the interior of the boxed mechanism 1, protecting the internal structure of the boxed mechanism 1, and saving the maintenance cost of the equipment.
