Background

The offshore wind power operation and maintenance ship can be roughly divided into a common operation and maintenance ship, a professional operation and maintenance ship, an operation and maintenance mother ship and a self-elevating operation and maintenance ship according to different functions. 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 which mainly have the task of rapidly transporting operation and maintenance personnel and small-sized parts.

However, the common operation and maintenance ship has poor wind and wave resistance, and when the ships are close to the tower of the offshore wind turbine, the ships can generate obvious swinging motion and heaving motion under the action of sea waves, so that the landing ladder swings, the difficulty of a maintenance worker for climbing onto the tower of the wind turbine from the ship is increased, and meanwhile, the operation and maintenance worker is easy to fall and fall.

After the operation and maintenance ship body 1 is parked, the landing ladder 23 is connected with the hydraulic lifter 22, and the landing ladder 23 is driven to ascend through the hydraulic lifter 22. After the landing ladder 23 rises to a designated position, the second motor 27 is started to drive the gear 28 to rotate, when the gear 28 rotates, the moving directions of the two racks 29 are opposite, so that the first clamping jaw 32 and the second clamping jaw 33 which are correspondingly connected with the racks 29 simultaneously clamp the climbing ladder 24 arranged on the offshore wind power pile, and the landing ladder 23 is fixed with the climbing ladder 24 through the clamping device 25, so that the stability of a person in moving on the climbing ladder 24 is improved.

When the operation and maintenance ship body 1 shakes and inclines to one side when encountering stormy waves, the bottom plate 2 tends to incline to one side along with the shaking of the operation and maintenance ship body 1. The draw gear 5 with fortune dimension ship body 1 slope opposite side starts on the bottom plate 2, and then the pulling balancing piece 4 outwards slides, make two balancing pieces 4 on the 2 incline direction of bottom plate different to the arm of force between the 2 pin joints of bottom plate, and then the moment that two balancing pieces 4 produced is different, the moment that the balancing piece 4 of 2 incline direction opposite sides of bottom plate produced is greater than the moment that 2 incline direction balancing pieces 4 of bottom plate produced, through the rocking of fortune dimension ship body 1 to the bottom plate 2 production with balanced stormy waves. The specific principle of the traction device 5 is as follows: the first motor 15 is started to drive the second belt pulley 16 to rotate, the second belt pulley 16 drives the first belt pulley 14 to rotate through the synchronous belt 17, and then the first nut 13 is driven to rotate through the first belt pulley 14, because the first screw 12 is fixed and does not rotate, and the first nut 13 is rotationally connected with the nut seat 18, so that the first nut 13 slides on the outer wall of the screw, the first nut 13 drives the whole mounting plate 8 to slide through the nut seat 18, so that the first motor 15 and the traction support 9 arranged on the mounting plate 8 move together, the first motor 15 and the first nut 13 move together, the synchronous belt 17 is prevented from being distorted and deformed, the traction support 9 moves to drive the balance block 4 to slide on the bottom plate 2 through the traction block 10, the distance from the balance block 4 to the hinged point of the bottom plate 2 is changed, the torque is further changed, and the inclined bottom plate 2 is.
