Disclosure of Invention
An object of the utility model is to provide a simple structure and work fast and stable's offshore wind power facility installation ship to reduce installation ship's structural complexity and manufacturing cost, and improve offshore wind power facility's installation effectiveness.
The utility model relates to an offshore wind power facility installation ship, which comprises a main ship body provided with a crane, wherein a plurality of supporting legs are horizontally hinged on two sides of the main ship body respectively; the main hull is also provided with a support driver for driving the supporting legs to rotate towards the bottom direction of the main hull and a recovery driver for driving the supporting legs to rotate back to the bottom direction of the main hull.
The offshore wind power facility installation ship drives the main ship body to a required position for the construction of the offshore wind power facility; then, the supporting legs arranged on the two sides of the main hull rotate around the hinged ends of the supporting legs and the main hull towards the bottom of the main hull, and the tail ends of the supporting legs gradually sink to the seabed position along with the rotation of the supporting legs; then, the support driver continuously applies acting force rotating towards the bottom of the main hull to the support legs, so that the tail ends of the support legs are stably and strongly abutted against the seabed; at the moment, the support legs support and fix the main ship body, and the crane and various devices on the main ship body can be used for installing the offshore wind power facility; and after the offshore wind power facility is installed, the support driver stops acting, and the recovery driver drives the support legs to reversely recover and leave the seabed. This offshore wind power facility installation ship sets up the supporting leg that can insert on the seabed in main hull both sides to very make things convenient for, fast and stably support and fix the main hull, its simple structure can reduce manufacturing cost, has satisfied the installation of offshore wind power facility again simultaneously well and needs, and can effectively improve the installation effectiveness of offshore wind power facility.

Detailed Description
An offshore wind power facility installation ship comprises a main ship body 1 provided with a crane 2, wherein a plurality of supporting legs 3 are horizontally hinged on two sides of the main ship body respectively; the main hull is also provided with a support driver for driving the supporting legs to rotate towards the bottom direction of the main hull and a recovery driver for driving the supporting legs to rotate back to the bottom direction of the main hull.
The offshore wind power facility installation vessel has the advantages that the tail ends of the supporting legs can be arranged to be in a tip shape, a three-fork structure and the like, so that the supporting legs can be inserted into the seabed more easily and stably. Or as shown in fig. 1-4, the support sheet 4 is fixed at the end of the support leg 3, and the support sheet can be set into different shapes according to the requirement, so as to be better inserted into the seabed and support the main hull, meanwhile, the support sheet 4 can be provided with a chamber inside, and the support sheet is provided with a water flowing hole communicated to the inner chamber, so that the seawater automatically enters the support sheet after entering the water, thereby reducing the buoyancy and improving the support stability, and meanwhile, after the support sheet leaves the sea, the seawater can be automatically discharged, reducing the weight, and facilitating the transportation or reducing the power requirement of the installation ship. Or, a closed chamber can be arranged in the supporting sheet 4, a ballast pump is arranged on the main hull 1 and is communicated with the closed chamber of the supporting sheet through a pipeline, so that seawater is injected into the supporting sheet after the supporting sheet is sunk to the seabed, the supporting stability is improved, and the seawater in the supporting sheet can be discharged after the offshore wind power facility is installed, so that the weight of the supporting sheet is reduced, the buoyancy of the supporting sheet is improved, and the supporting leg can be recovered more conveniently.
Offshore wind power facilities installation ship, supporting leg 3 is rotatable to the vertical state, installs mount 5 on the main hull 1, installs the binding structure of locating the supporting leg of vertical state on the mount between mount and the supporting leg. Therefore, the supporting legs are contracted when the installation ship moves, and collision between the installation ship and the surrounding environment is avoided. The binding structure can be a fixing bolt and an eye plate, and can also be a binding rope or other structures capable of fixing the supporting leg. In addition, the main hull 1 is also provided with a telescopic pusher, the tail end of the pusher is opposite to the supporting leg 3 in a vertical state, acting force towards the outer side of the main hull can be applied to the supporting leg, and pushing force can be applied to the supporting leg after the binding structure is unbound, so that the supporting leg falls into the sea.
The offshore wind power facility installation vessel, the support driver, the recovery driver and the pusher can be hydraulic oil cylinders or other mechanical devices capable of realizing related functions. The recovery driver can also be as shown in fig. 2 and 4, and comprises a winch 6 and a stay cable 7, wherein one end of the stay cable is installed on the winch, the other end of the stay cable is fixedly connected with the supporting leg 3 or the supporting sheet 4, the supporting leg is driven to be recovered through the winch and the stay cable, and the recovery driver is simple in structure and works quickly and stably.
As shown in fig. 1-4, P is the sea level and Q is the sea bed. Before starting working, driving the installation vessel to the installation position of the offshore wind power facility; then, the binding between the supporting leg and the fixed frame is released; then, the pusher applies thrust to the support leg, so that the support leg deviates from the vertical position and descends to the sea under the action of self weight, as shown in FIG. 2; then, the supporting legs will continue to descend to the seabed until the supporting sheets fall on the seabed; at this time, the ballast pump injects water into the closed chamber in the support sheet through the pipeline, and the support driver applies a stable rotational force to insert the support sheet into the seabed to form a stable support, as shown in fig. 3; after the support is stable, the crane and various devices on the main hull can be used for installing the offshore wind power facility; until the offshore wind power facility is installed, the ballast pump discharges the seawater in the supporting sheet, and the winch drives the supporting leg to be recovered to a vertical state through the inhaul cable; then, the supporting leg is fixed on the fixing frame by using the binding structure again, as shown in fig. 4; thereby completing all installation work. The offshore wind power facility is simple in structure and easy to manufacture, can meet the requirement for installation of the offshore wind power facility, and can effectively improve the installation efficiency of the offshore wind power facility.
