Description

Technical Field

[0001] The present invention relates to the field of offshore wind power, and in particular to an integrated grouting vessel mooring and charging platform for an offshore wind power conductor frame. Background Art

[0002] Offshore wind turbine jackets are a crucial foundational structure supporting offshore wind turbines, typically consisting of pile foundations and an upper frame. This structural design primarily aims to provide stable load-bearing capacity to withstand the complex wind and wave conditions at sea. However, existing jacket structures are limited in their functionality, essentially solely supporting the turbines without considering coordination with grouting vessels or energy supply requirements.

[0003] Grouting vessels, core equipment for grouting and reinforcing foundation structures during wind turbine construction, require long and delicate operations near jackets. Existing jackets lack reliable berthing and energy resupply, making positioning and operation difficult in complex sea conditions. Furthermore, most grouting vessels currently rely on shore-based refueling. When operating offshore, difficulties in obtaining energy directly impact operational continuity.

[0004] Furthermore, traditional jacket structures lack power supply interfaces or docking facilities, resulting in a lack of effective coordination between vessels and wind turbine structures. This increases construction risks and impacts overall project progress and economic viability. Therefore, developing a jacket structure that integrates grouting vessel berthing and direct power supply functions has become a new approach to addressing these issues. Summary of the Invention

[0005] The object of the present invention is to provide an integrated grouting vessel mooring and charging platform for an offshore wind power conductor frame, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions: An integrated grouting vessel mooring and charging platform for an offshore wind turbine jacket, the integrated grouting vessel mooring and charging platform being cooperatively installed at the bottom of a foundation platform of a jacket foundation, comprising: Two left and right floating charging platforms, the two left and right floating charging platforms respectively slidingly cooperate with the base platform; A platform driving device, which drives the left and right floating charging platforms to move toward or away from each other; Two left and right groups of water propulsion devices, the two left and right groups of water propulsion devices are respectively installed on the left and right groups of floating charging platforms, and are used to attract the grouting vessel to between the left and right groups of floating charging platforms; and A platform charging device is provided on a floating charging platform for charging a grouting vessel.

[0007] Furthermore, the floating charging platform is slidably matched with a first guide rail laid along the left-right direction at the bottom of the basic platform.

[0008] Furthermore, the platform driving device is a hydraulic rod arranged at the bottom of the basic platform.

[0009] Furthermore, the water propulsion device includes an external mesh box and an impeller arranged in the external mesh box. The impeller is arranged in the front-to-back direction, which makes the water flow forward, thereby making the grouting ship follow the water flow into between the left and right groups of floating charging platforms.

[0010] Furthermore, the integrated grouting ship mooring and charging platform also includes two left and right multi-point flexible fixing components, which are respectively installed on the left and right groups of floating charging platforms. The multi-point flexible fixing components include several flexible telescopic fixing mechanisms arranged at intervals along the front and rear directions, and the flexible telescopic fixing mechanisms are used to position the grouting ship.

[0011] Furthermore, the flexible telescopic fixing mechanism is a hydraulic rod.

[0012] Furthermore, the platform charging device includes a charging pile and a charging pile driving mechanism for driving the charging pile to move in the front-rear direction.

[0013] Furthermore, the charging pile is slidably engaged with a second guide rail laid on the floating charging platform along the front-to-back direction.

[0014] The present invention provides a charging method for the integrated grouting vessel mooring charging platform as described above, comprising: Step 1: When the grouting vessel approaches the integrated grouting vessel mooring and charging platform, the grouting vessel is attracted to the space between the left and right floating charging platforms by the water propulsion device; Step 2: Use the platform driving device to drive the left and right floating charging platforms closer to each other to position the grouting vessel; Step 3: Charge the grouting vessel through the platform charging device.

[0016] 2) Adjustable floating platform: Using drive and guide rail technology, the platform can be moved in both directions and adjusted flexibly to suit the size and operation requirements of different grouting vessels.

[0017] 3) Flexible platform charging device: A movable platform charging device is set on the floating platform, and the charging contact point is adjusted according to the change of the berthing point position to meet the charging needs of different grouting vessels.

[0018] 4) Multi-point flexible fixing system: Multiple rows of flexible telescopic fixing mechanisms with flexible structures are arranged on the walls on both sides. Each flexible telescopic fixing mechanism can independently adjust the length to adapt to the shape of different parts of the hull, ensuring the stability of the hull and adaptability to various complex sea conditions.

[0019] 5) Water flow assisted positioning device: A row of water flow propulsion devices is installed at the bottom of the platform to assist the ship in berthing and adjusting its position through the directional effect of the water flow, thereby improving the safety and accuracy of berthing.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 7 An integrated grouting vessel mooring and charging platform for an offshore wind turbine jacket is disclosed. The integrated grouting vessel mooring and charging platform 2 is mounted on the bottom of the jacket foundation 1's base platform 100, allowing grouting vessels to enter and exit. The integrated grouting vessel mooring and charging platform 2 includes two left and right floating charging platforms 200, a platform drive 201, two left and right water propulsion devices 202, two left and right multi-point flexible fixing assemblies 203, and a platform charging device 204. The left and right floating charging platforms 200 slide relative to the base platform 100. The platform drive 201 drives the two floating charging platforms 200 toward or away from each other, controlling the distance between the two platforms to accommodate different grouting vessel sizes. The left and right water propulsion devices 202 are mounted on the lower ends of the two floating charging platforms 200, respectively. The water propulsion devices 202 are located underwater and are used to draw the grouting vessel between the two floating charging platforms 200. The left and right multi-point flexible fixing assemblies 203 are mounted on the left and right floating charging platforms 200, respectively. These assemblies comprise several flexible, retractable fixing mechanisms spaced apart along the fore-aft direction, which are used to position the grouting vessel. A platform charging device 204 is installed on the floating charging platforms 200, above the water surface, to charge the grouting vessel. The platform charging device 204 can be installed on both floating charging platforms 200, or on only one floating charging platform 200.

[0031] Continue reading Figure 2 and Figure 3In one embodiment of the present invention, the floating charging platform 200 is slidably engaged with a first guide rail 205 laid along the left-right direction at the bottom of the base platform 100. The platform driving device 201 is a hydraulic rod provided at the bottom of the base platform 100. The hydraulic rod can adopt a dual-output shaft hydraulic rod. The two ends of the dual-output shaft hydraulic cylinder are respectively connected to the floating charging platform 200. The dual-output shaft hydraulic rod can synchronously drive the two groups of floating charging platforms 200 to move synchronously in opposite directions. Alternatively, the platform driving device 201 can also use two hydraulic rods to drive the two groups of floating charging platforms 200 to move separately.

[0032] In another embodiment of the present invention, the platform driving device 201 may also adopt an electric driving mechanism.

[0033] Continue reading Figure 6 and Figure 7 In one embodiment of the present invention, the water propulsion device 202 includes an external mesh box 2020 and a plurality of impellers 2021 arranged in the external mesh box 2020 along the front-to-back direction. The impellers 2021 are arranged along the front-to-back direction, which makes the water flow forward, thereby allowing the grouting ship to follow the water flow and enter between the left and right groups of floating charging platforms 200. When the grouting ship needs to leave, the impellers 2021 can also drive the grouting ship to leave by reversing.

[0034] When the grouting vessel enters the entrance, the grouting vessel cannot be started due to safety reasons. The water propulsion device 202 controls the direction of the water flow to slowly and safely drive the vessel to the middle position of the platform.

[0035] Continue reading Figure 5 In one embodiment of the present invention, the flexible, telescopic fixing mechanism is preferably a hydraulic rod, though an electric push rod or the like may also be used. Flexible structures such as rubber blocks are disposed at the outer ends of the flexible, telescopic fixing mechanism. The multi-point flexible fixing assembly 203 supports the vessel from both sides by extending multiple hydraulic rods. The large number of hydraulic rods allows the assembly to adapt to the vessel's shape, thereby achieving mooring.

[0036] Continue reading Figure 5 In one embodiment of the present invention, the platform charging device 204 includes a charging station 2040 and a charging station drive mechanism 2041 for driving the charging station 2040 in a forward and backward direction. The charging station 2040 slides with a second guide rail 206 provided along the forward and backward direction on the floating charging platform 200. The charging station drive mechanism 2041 can be implemented using a nut-screw mechanism, a hydraulic rod, a rack and pinion transmission mechanism, or other mechanisms.

[0037] See also Figure 8 The present invention also provides a charging method for the integrated grouting vessel mooring charging platform as described above, comprising: Step 1: When the grouting vessel approaches the entrance of the integrated grouting vessel mooring and charging platform 2, in order to prevent the grouting vessel from colliding with the platform, the grouting vessel is slowed down, and then the water propulsion device 202 is started to attract the grouting vessel to between the left and right groups of floating charging platforms 200.

[0038] Step 2: Use the platform driving device 201 to drive the left and right floating charging platforms 200 closer to each other, and use the multi-point flexible fixing component 203 to position the side of the grouting ship. The multi-point flexible fixing component 203 can adapt to the irregular shape of the grouting ship through the extension and contraction of the hydraulic rod.

[0039] Step 3: After the grouting vessel is positioned and stabilized, the crew can use the remote control to control the platform charging device 204. The charging pile drive mechanism 2041 drives the charging pile 2040 to move to the position corresponding to the grouting vessel's charging port. The charging pile 2040 has a built-in coiled charging cable. The crew controls the charging pile 2040. When the charging pile 2040 is near the vessel's charging point, the crew removes the coiled cable from the charging pile 2040 and inserts it into the grouting vessel to complete charging. After charging is complete, the grouting vessel can be driven away from the charging position by rotating the impeller 2021 in the opposite direction.

[0040] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
