Problems solved by technology

[0003]The lifting mechanism of the above-mentioned self-elevating wind power installation platform and the self-elevating offshore platform in the prior art usually adopt integrated pile legs, which can be moved or carried out on the offshore platform. At any stage of seabed fixation, the legs are kept vertical to the lifting splint. This kind of vertical leg structure is likely to cause the following problems: 1. During the movement of the offshore platform, it is usually necessary to lift the legs to a certain height above sea level , due to the heavy weight of the pile legs, the center of gravity of the entire offshore platform will move upwards, and the risk of rollover will easily occur when encountering sea waves; The legs are affected by undercurrents in different directions during the movement, which hinders the movement of the offshore platform and increases the risk of the legs hitting rocks; 3. Affected by the height from the sea surface to the seabed, the length of the existing legs even reaches one or two hundred meters , the pile legs of such length are usually transported to the installation sea area in sections, and installed as a whole by hoisting, which requires a lot of time, financial resources and manpower

Embodiment 1

[0032] A self-elevating multi-functional offshore platform, comprising a lifting deck 1, a plurality of lifting pile grooves 2 are opened on the lifting deck 1, and rotating sides 3 are fixedly installed on both sides of the lifting deck 1 at the bottom of the lifting pile grooves 2. The opposite side of the rotation side 3 of the rotating shaft 4 is movably equipped with a leg lifting sleeve 5, and the lower leg 6 is movably arranged in the leg lifting sleeve 5 through a moving mechanism, and the leg lifting sleeve 5 is driven by a rotating motor. Drive the lower leg 6 to switch between horizontal and vertical working modes;

[0033] The upper leg 7 is also movably inserted in the lifting pile groove 2, and the upper connecting seat 8 is fixedly installed on the bottom of the upper leg 7, and the lower connecting seat 9 that is movably matched with the upper connecting seat 8 is fixedly installed on the lower leg 6 top. Both the connecting seat 8 and the lower connecting seat...

Embodiment 2

[0037] In this embodiment, the buoyancy airbag 11 is arranged at the gap of the lower leg 6 away from the end of the lower connecting seat 9. By setting the buoyancy airbag 11 at the end far away from the lower connecting seat 9, when it is necessary to adjust the lower leg 6 from the vertical state When the horizontal state is reached, the setting of the buoyancy airbag 11 can provide upward buoyancy at the tail end of the lower leg 6, thereby reducing the pressure of the rotating motor, so that the lower leg 6 can be adjusted to the horizontal state under the buoyancy of the buoyancy airbag 11 .

Embodiment 3

[0039] In this embodiment, the buoyancy airbag 11 is arranged in the gap of the whole section of the lower leg 6 . By arranging the buoyancy airbag 11 in the whole section, the upward buoyancy can be better provided, and at the same time, the gravity of the lower leg 6 can be better balanced.

Abstract

The invention provides a self-elevating multifunctional ocean platform and an operation method thereof.The self-elevating multifunctional ocean platform comprises a lifting deck, a plurality of lifting pile grooves are formed in the lifting deck, and rotating side edges are fixedly installed on the two sides, at the bottoms of the lifting pile grooves, of the lifting deck correspondingly; pile leg lifting sleeves are movably mounted on the opposite sides of the rotating side edges on the two sides through rotating shafts, and the pile leg lifting sleeves are driven by a rotating motor to drive the lower pile leg to conduct working mode switching in the horizontal direction or the vertical direction; according to the pile leg, the upper pile leg body and the lower pile leg body are arranged in a separated mode, in the moving process of the lifting deck, the lower pile leg body is kept parallel to the lifting deck under driving of the pile leg lifting sleeve, and therefore the problem that energy consumption or the overturning risk is increased due to the fact that the pile leg is perpendicular to the lifting deck all the time is completely solved; and meanwhile, the lower pile leg structure arranged in parallel is adopted, later pile leg hoisting is not needed in the moving process of the lifting deck, the installation time is greatly saved, and manpower and material resources are saved.
