Description

Technical Field

[0001] This invention relates to the field of offshore operation and maintenance technology, and in particular to an offshore wind farm operation and maintenance device. Background Technology

[0002] The surge in demand for offshore wind power in my country is driving up the demand for offshore wind power operation and maintenance (O&M). Offshore wind power O&M vessels are specialized ships used for the operation and maintenance of offshore wind turbine generators. However, due to the complex conditions in my country's sea areas, offshore wind power O&M vessels are significantly affected by the marine environment when conducting offshore operations, especially when working alongside wind turbines. Therefore, related technologies provide operational windows for offshore wind power O&M vessels, ensuring that O&M operations can "go out, go up, and come back," thereby guaranteeing the safety of offshore wind power O&M operations and avoiding situations where operations are impossible after departure, thus reducing the operating costs of O&M vessels.

[0003] However, the number of days available for operation and maintenance each year is limited, especially in provinces like Fujian, where the window for offshore wind power operation and maintenance is short due to relatively high wind speeds. Constrained by weather, waves, and other natural conditions, operation and maintenance work may involve certain safety risks, both during offshore wind turbine maintenance and during ship transportation.

[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] Offshore wind farm operation and maintenance equipment according to embodiments of the present invention, such as Figures 1 to 3 As shown, the offshore wind farm operation and maintenance equipment includes a guiding device, a submersible 2, and a lifting device. The guiding device is installed on the wind turbine foundation platform 1 and adjacent wind turbine foundation platforms 1. The submersible 2 is connected to the guiding device and moves along the guiding device between the wind turbine foundation platform 1 and adjacent wind turbine foundation platforms 1. The lifting device is installed on the submersible 2 to lift the submersible 2 to the wind turbine foundation platform 1. The submersible 2 can dive into the ocean to avoid the strong influence of wind and waves on the ocean surface. The guiding device guides the submersible 2 to move between the wind turbine foundation platform 1 and adjacent wind turbine foundation platforms 1, forming a fixed navigation track to avoid deviation and reduce the risk of operation and maintenance. The lifting device lifts the submersible 2 to the height of the ladder on the wind turbine foundation platform 1, facilitating personnel access to the wind turbine foundation platform 1.

[0023] The offshore wind farm operation and maintenance device according to embodiments of the present invention has the advantage of being less affected by environmental conditions such as ocean winds and waves.

[0024] In some embodiments, such as Figures 1 to 3 As shown, the guiding device includes a drive wheel 4 and a guide cable 3. The drive wheel 4 is connected to the submersible 2. The surface of the drive wheel 4 has drive teeth that cooperate with the guide cable 3. The two ends of the guide cable 3 are connected to the wind turbine foundation platform 1 and the adjacent wind turbine foundation platform 1, respectively.

[0025] Specifically, the submersible 2 drives the drive wheel 4 to rotate, and the drive wheel 4 moves along the guide cable 3, thereby driving the submersible 2 to move along the guide cable 3. The forward and reverse rotation of the drive wheel 4 enables bidirectional travel between the two wind turbine foundation platforms 1.

[0026] In some embodiments, such as Figures 2 to 3 As shown, the submersible 2 includes a first power unit, which is connected to the drive wheel 4 via a transmission.

[0027] Specifically, the first power unit is installed inside the submersible 2, and part of the first power unit is connected to the drive wheel 4 for transmission. The guide cable 3 is located between the drive wheel 4 and the submersible 2.

[0028] In some embodiments, such as Figure 3 As shown, the first power unit includes a first gear 5, a transmission component 6, and a motor 7. One end of the drive wheel 4 is connected to the first gear 5, and the motor 7 is connected to the first gear 5 through the transmission component 6.

[0029] Specifically, the motor 7 is located inside the submersible 2, and the transmission component 6 can be a transmission belt or a transmission chain. The motor 7 drives the transmission belt, which in turn drives the first gear 5 to rotate. The rotation of the first gear 5 drives the drive wheel 4 to rotate, and the rotation of the drive wheel 4 drives the submersible 2 to move along the guide cable 3.

[0030] In some embodiments, such as Figure 3 As shown, the drive wheel 4 is a dumbbell-shaped drive wheel 4, and the drive teeth are located in the middle area of ​​the dumbbell-shaped drive wheel 4.

[0031] Specifically, when the drive wheel 4 is dumbbell-shaped, it can prevent the guide cable 3 from slipping out of the center of the drive wheel 4 and coming off, thus ensuring the stability of the submersible 2.

[0032] In some embodiments, the lifting device includes a limiting member 8 located at the end of the drive wheel 4 away from the first gear 5 and a lifting rope located on the wind turbine foundation platform 1.

[0033] Specifically, the limiting member 8 is used to wind up the ascending rope, and as the drive wheel 4 rotates, it lifts the submersible 2 to the ladder height of the wind turbine foundation platform 1. The limiting member 8 can be a buckle.

[0034] In some embodiments, such as Figure 3 As shown, the limiting component 8 is a hook.

[0035] Specifically, the hook is located on the side of the drive wheel 4 away from the first gear 5. When the submersible 2 needs to be raised, the submersible 2 is moved so that the ascending rope enters the hook. The motor 7 is started to drive the first gear 5 and then drive the drive wheel 4 to rotate. The rotation of the drive wheel 4 causes the ascending rope to be wound on the surface of the drive wheel 4, and the ascending rope drives the submersible 2 to rise.

[0036] In some embodiments, such as Figure 2 As shown, the submersible 2 has a second power unit 9.

[0037] Specifically, the second power unit 9 can be a propeller or other submarine power drive unit to ensure that the submersible 2 can move independently after detaching from the guide cable 3 under special circumstances.

[0038] In some embodiments, such as Figure 3 As shown, the submersible 2 has a drainage mechanism 11, which is located on both sides of the submersible 2.

[0039] Specifically, the drainage mechanism 11 is located on both sides of the submersible 2. When the submersible 2 needs to float, the drainage mechanism 11 is emptied to increase the buoyancy of the submersible 2, and the submersible 2 floats smoothly.

[0040] In some embodiments, such as Figure 3 As shown, the submersible 2 also includes a manual crank handle 10, which is connected to the transmission component 6.

[0041] Specifically, the manual crank handle 10 is connected to the transmission component 6 to prevent the drive wheel 4 from being unable to move when the motor 7 in the first power device is damaged. The drive wheel 4 can be rotated by manually cranking the manual crank handle 10.
