Description

Technical Field

[0001] This utility model relates to the technical field of marine outrigger structures, specifically to a truss-type outrigger applied to an offshore wind power installation vessel. Background Technology

[0002] Offshore wind power refers to wind power generation equipment installed on the ocean. Because it is installed in the ocean, special vessels are needed to transport and install the wind power generation components. There are many types of offshore wind power installation vessels, but the basic operating principle is the same: the hull is pushed out of the water by outriggers to ensure the stability of the hull, and lifting equipment is used to transport and lift the components.

[0003] The outriggers of wind turbine installation vessels need to be lowered to the seabed and rest on the sea surface. Therefore, it is necessary to reduce the contact area between the outriggers and the seawater. Currently, truss-type outriggers are basically used, which can ensure the support force while reducing the impact of seawater waves on the outriggers. However, a base needs to be installed at the end of the outrigger that contacts the seabed to increase the stability of the support. Currently, the volume of the base is fixed, which results in a fixed contact area with the seabed. The contact area cannot be expanded as needed, which reduces stability and flexibility. Therefore, a truss-type outrigger for offshore wind turbine installation vessels is proposed here. Utility Model Content

[0004] The technical problem this invention aims to solve is that the current base volume is fixed, resulting in a fixed contact area with the seabed. This prevents the contact area from being expanded as needed, reducing stability and flexibility. This invention provides a truss-type support leg for offshore wind power installation vessels, which allows for adjustment of the base's contact area and coverage as needed, increasing the contact area between the base and the seabed and improving application flexibility.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a truss-type support leg applied to an offshore wind power installation vessel, including a base, a pressure plate detachably embedded in the middle of the top side wall of the base, a truss fixedly connected to the top side wall of the pressure plate, an extension plate fixedly connected to the base through its four outer walls, the extension plate having a double-layer structure, four support arms rotatably connected inside the extension plate, movable arms telescopically inserted inside the support arms, an embedded column detachably embedded at one end of the movable arm, a lifting column provided inside the embedded column, and a docking plate provided at the bottom of the lifting column.

[0006] As a preferred technical solution of this utility model, a connecting plate is fixedly connected to the middle of the bottom side wall of the lifting column, a pair of docking plates are provided, a cone-shaped expansion plate is fixedly connected to the bottom side wall of the docking plate, and a driver is detachably connected to both sides of the connecting plate away from the lifting column.

[0007] As a preferred embodiment of this utility model, the output end of the driver is fixedly connected to a rotating shaft, and the side wall of the docking plate opposite to the rotating shaft is provided with a rotating groove. The docking plate is detachably connected to the rotating shaft through the rotating groove.

[0008] As a preferred technical solution of this utility model, a horizontal telescopic rod is detachably connected to one end side wall of the support arm, and the output end of the horizontal telescopic rod is detachably connected to one end side wall of the movable arm located inside the support arm. A vertical telescopic rod is detachably connected to the top side wall of the embedded column, and the output end of the vertical telescopic rod is detachably connected to one end side wall of the lifting column extending into the embedded column. Two sealing rings are embedded in the outer ring wall of the lifting column.

[0009] As a preferred technical solution of this utility model, a waterproof brushless motor is detachably embedded in the top of the extension plate and the side wall near the four corners. A rotating column is rotatably connected between the two side walls of the two extension plates near the four corners and opposite to each other. One end of the support arm is detachably connected to one side of the rotating column. The output end of the waterproof brushless motor is detachably connected to the top of the rotating column.

[0010] This utility model has the following advantages: When needed, the waterproof brushless motor is started to rotate the corresponding support arm from between the two extension plates via the rotating column. Then, as needed, the horizontal telescopic rod is started to drive the movable arm to extend to a suitable length. Finally, the vertical telescopic rod is started to push the lifting column downward. Before this, the driver on the connecting plate is started to drive the docking plate to rotate, so that it changes from a vertical to a horizontal state, thereby making the expansion plate fit against the seabed. This can effectively increase the support area and improve the stability of the support based on the base. Moreover, because the four support arms are located at the four corners, they can provide additional anti-tilting support, ensuring the stability of the truss and the hull, and are easy to deploy and retract.

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] Please refer to the following: Figure 1-3 This utility model discloses a truss-type support leg for an offshore wind power installation vessel, comprising a base 1, a pressure plate 2 detachably embedded in the middle of the top side wall of the base 1, a truss 3 fixedly connected to the top side wall of the pressure plate 2, and an extension plate 4 fixedly connected to the base 1 through its four outer walls. The extension plate 4 has a double-layer structure, and four support arms 7 are rotatably connected inside the extension plate 4. Movable arms 8 are telescopically inserted into the support arms 7, and an embedded column 9 is detachably embedded in one end of the movable arm 8. A lifting column 10 is provided inside the embedded column 9. A horizontal telescopic rod 14 is detachably connected to one end of the inner side wall of the support arm 7. The output end of the horizontal telescopic rod 14 is detachably connected to one end of the movable arm 8 located inside the support arm 7. A vertical telescopic rod 15 is detachably connected to the top side wall of the embedded column 9. The output end of the vertical telescopic rod 15 is detachably connected to one end of the lifting column 10 extending into the embedded column 9. Two sealing rings 16 are inlaid and connected to the outer ring wall of the lifting column 10.

[0015] The technical effects of this solution are as follows: First, the truss 3 is lowered into the sea via the base 1. Once the base 1 is in contact with the seabed and the support is stable, the waterproof brushless motor 5 is activated as needed. The waterproof brushless motor 5 controls the rotating column 6 to rotate the support arm 7, thereby rotating the support arm 7 out. After rotating to the required angle, the horizontal telescopic rod 14 is activated to push out the movable arm 8, thereby adjusting the expansion area. After the movable arm 8 extends to the specified length, the vertical telescopic rod 15 is activated to push the lifting column 10 out from the embedded column 9. The two docking plates 12 are pre-adjusted to a horizontal state by the driver 17, so that the expansion plate 13 fits tightly with the seabed. The above can effectively increase the coverage area, and the four support arms 7 and their components can provide additional anti-tilting support.

[0016] A docking plate 12 is provided at the bottom of the lifting column 10. A connecting plate 11 is fixedly connected to the middle of the bottom side wall of the lifting column 10. A pair of docking plates 12 are provided. A cone-shaped expansion plate 13 is fixedly connected to the bottom side wall of the docking plate 12. Drivers 17 are detachably connected to both sides of the connecting plate 11 at the end away from the lifting column 10. A rotating shaft is fixedly connected to the output end of the driver 17. A rotating groove 18 is opened on the side wall of the docking plate 12 opposite to the rotating shaft. The docking plate 12 is detachably connected to the rotating shaft through the rotating groove 18. A waterproof brushless motor 5 is detachably embedded in the top of the extension plate 4 and the side wall near the four corners. A rotating column 6 is rotatably connected between the two extension plates 4 near the four corners and opposite side walls. One end of the support arm 7 is detachably connected to one side of the rotating column 6. The output end of the waterproof brushless motor 5 is detachably connected to the top of the rotating column 6.

[0017] The technical effects of this solution are as follows: Since the docking plate 12 is connected to the lifting column 10 through the connecting plate 11, the folding of the docking plate 12 can effectively reduce the space occupied and ensure that it can be completely retracted into the two extension plates 4. At the same time, the connection of the extension plates 4 can increase the volume of the base 1 itself, increase the contact area, and increase the stability of the support. Each rotating column 6 is connected to a separate waterproof brushless motor 5, so that the rotation angle of each support arm 7 can be independently controlled, improving the flexibility of application. The pressure plate 2 can detect the support status and prevent the support from becoming weak, which would affect the support of the ship.

[0018] Specifically, when using this utility model, the pressure plate 2 is used to determine whether the base 1 provides stable support. Because the seabed is soft, it will compress downwards under force. Only when it is fully compressed can it provide stable support for the hull. Before that, the pressure changes in real time. Based on the pressure data, it can be determined whether the base 1 is stably supported on the seabed. Once stable, the waterproof brushless motor 5 is started as needed to rotate the corresponding support arm 7 to a suitable angle via the rotating column 6. Then, the horizontal telescopic rod 14 and the vertical telescopic rod 15 are started in sequence to push out the movable arm 8 and the lifting column 10. Before this, the driver 17 is started in advance to rotate the docking plate 12 to a horizontal state, thereby ensuring full contact with the seabed and providing stable additional support for the base 1, improving the anti-tilting performance.

[0019] The components mentioned in this application for use in the sea, such as the horizontal telescopic rod 14 and the vertical telescopic rod 15, are all highly waterproof underwater-specific equipment that can effectively prevent water ingress and other problems.

[0020] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0021] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
