Problems solved by technology
[0002] Since the jack-up wind power installation ship needs to lift the work deck to the water area during the operation, it is inevitable that it will frequently slam against the waves, which will not only cause great damage to the hull structure, but also cause damage to the wind turbine blades. Installation has brought great difficulties
In addition, since the legs of the jack-up wind power installation ship are self-elevating truss structures, compared with conventional cylindrical legs, the section modulus is smaller, so the legs are prone to fatigue under the slamming action of waves damage

Abstract
The invention discloses a slamming prevention device which comprises 2N fixing parts and at least one gravity device, wherein the fixing parts are arranged at the bottom of a ship at intervals, the fixing parts are arranged in a rectangular array mode, sliding ways are arranged on the fixing parts in the vertical direction, N being a positive integer larger than 1; and the gravity devices are arranged on the slide ways on the four adjacent fixing parts in a sliding manner and can slide up and down along the slide ways. According to the slamming prevention device, when the ship body is slammed by waves, energy of wave slamming can be converted into gravitational potential energy and kinetic energy of the gravity device, and the gravity devices slide up and down in the slide ways, so that large pressure at the moment of wave slamming is effectively decomposed, the main ship body structure is prevented from being damaged, meanwhile, pile legs of the wind power ship are also protected, and the fatigue life of the pile leg is prolonged; and the whole slamming prevention device is simple in structure and easy to mount and dismount, slamming force of waves can be effectively decomposed, and the main hull and the pile legs are well protected.
Description
technical field [0001] The invention relates to the technical field of offshore equipment, in particular to an anti-slamming device. Background technique [0002] Since the jack-up wind power installation ship needs to lift the work deck to the water area during the operation, it is inevitable that it will frequently slam against the waves, which will not only cause great damage to the hull structure, but also cause damage to the wind turbine blades. Installation posed great difficulties. In addition, since the legs of the jack-up wind power installation ship are self-elevating truss structures, compared with conventional cylindrical legs, the section modulus is smaller, so the legs are prone to fatigue under the slamming action of waves damage. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes an anti-slamming device, which has a simple...
