Description

Anti-shaking device for offshore wind power operation and maintenance ship and wind power operation and maintenance ship

Technical Field

The invention relates to the technical field of offshore wind power operation and maintenance ships, in particular to an anti-swing device for an offshore wind power operation and maintenance ship and the wind power operation and maintenance ship.

Background

With the rapid development of the offshore wind power industry worldwide, more and more large wind turbine generators will be deployed offshore far from land. However, due to the influence of severe sea climate, inconvenient transportation and operation, the operation and maintenance efficiency of the offshore wind turbine is relatively lower than that of the onshore wind turbine. This also results in considerable maintenance and operation costs for offshore wind turbines, which in some way limits the rapid development of offshore wind power. Particularly, compared with onshore wind power, the offshore wind power generation system is influenced by severe offshore weather, and the operation and maintenance time window of an offshore wind power plant is very narrow, so that how to greatly improve the operation and maintenance efficiency of offshore wind power to realize rapid professional maintenance of offshore wind power generation equipment becomes an important link for ensuring safe and efficient production of offshore wind power in the future, and a wind power operation and maintenance ship is the most critical core equipment in the link. Therefore, along with the rapid development of the offshore wind power industry, the market of offshore wind power operation and maintenance ships can be greatly opened at home and abroad.

The offshore wind power operation and maintenance ship can be roughly divided into the following parts according to different functions: (1) a common operation and maintenance ship; (2) a professional operation and maintenance ship; (3) an operation and maintenance mother ship; (4) self-elevating operation and maintenance ship. The operation and maintenance mother ship and the self-elevating operation and maintenance ship are mainly used for storing, hoisting and replacing large parts (such as gear boxes, generators, blades and the like) of the wind generating set, so that the operation and maintenance ship generally has stronger hoisting and self-sustaining capabilities and also has very good wave resistance and wind wave resistance. However, such operation and maintenance vessels are expensive to use (or rent) and even comparable to the cost of offshore wind-powered installation vessels.

In addition, especially in humid and highly corrosive marine climates, the reliability of large parts (such as gear boxes, generators, blades and the like) of the offshore wind turbine is far higher than that of electronic components of an electric control system of the wind turbine, and frequent maintenance is generally not needed. Therefore, in the operation and maintenance practice of offshore wind power, the most frequently used are ordinary operation and maintenance ships and professional operation and maintenance ships which mainly have the task of rapidly transporting operation and maintenance personnel and small-sized parts. The two kinds of operation and maintenance ships have the characteristics of small size, economical use and convenience, and do not need to be used for storing, hoisting and replacing large parts of the wind generating set, so that the two kinds of operation and maintenance ships do not have strong hoisting capacity generally, and do not need to have too strict requirements on the dynamic stability. As such, in addition to the conventional ballast load of the hull and the stable design of the bilge keel, more advanced dynamic stabilization devices such as expensive fin stabilizer, tank stabilizer, high-speed gyroscope, etc. are not installed on these small wind power operation and maintenance ships.

In recent years, offshore wind power operation and maintenance practices at home and abroad show that due to poor motion stability of the small wind power operation and maintenance ships, when the small wind power operation and maintenance ships are used for offshore operation and maintenance, the ships often have difficulty in moving back and forth and carrying parts between the operation and maintenance ships and a fan bearing platform due to unstable ship bodies, even severe accidents such as damage or casualties of the parts occur, and the efficiency and the cost of offshore wind power operation and maintenance are seriously influenced. Therefore, how to improve the dynamic stability of the small-sized offshore wind power operation and maintenance ship during operation to the maximum extent without greatly increasing the capital investment is an urgent need for improving the safety level of the offshore wind power operation and maintenance operation and the efficiency of the offshore wind power operation and maintenance.

Theheave plate 2 and the push assembly are mounted on the mounting frame 1. When seawater and theheave plate 2 placed under the water move relatively, the motion damping of the operation and maintenance ship in the heave, roll and pitch directions is improved by utilizing the fluid resistance which acts on theheave plate 2 and is opposite to the motion direction of the heave plate, so that the purpose of improving the motion stability of the operation and maintenance ship in the three directions is achieved.

In this embodiment, theheave plate 2 is a circular plate, theheave plate 2 is fixed perpendicular to thepush rod 5, and thepush rod 5 is located at the center of theheave plate 2. Four reinforcingribs 21 are arranged between theheave plate 2 and thepush rod 5, and the four reinforcingribs 21 are uniformly distributed in the circumferential direction of theheave plate 2.

Then, thehydraulic motor 4 is controlled to rotate in the forward direction by thecontroller 43 of thehydraulic motor 4 to drive thepush rod 5 in the double-acting hydraulic cylinder 6 to move downward, so that theheave plate 2 is stably placed at a predetermined anti-sway position under water to stabilize the motion of the maintenance vessel in the three directions of heave, roll and pitch. When theheave plate 2 needs to be retracted from the water when the operation and maintenance ship finishes the operation and maintenance work, the two-way solenoid valve of thefirst control pipe 41 is firstly opened reversely, the two-way solenoid valve of thefirst oil pipe 71 and the two-way solenoid valve between thesecond control pipe 42 and the hydraulic cylinder 6 are opened forwardly.
