Description

[0001] This case is a divisional application based on the invention patent with application date of August 28, 2020, application number CN202010885603.X, and name “A method and device for installing an offshore wind power suction tube jacket” as the parent case. Technical Field

[0002] The present invention relates to the technical field of offshore engineering facilities, and in particular to a method and device for installing a suction tube jacket. Background Art

[0003] Offshore wind turbine foundations vary depending on the water depth, using various types of foundations, including monopiles, skirt piles, gravity-type, jacket, and floating. As my country's offshore wind power development expands from shallow waters to deep waters, three-pile suction-tube jacket foundations are becoming widely adopted due to their adaptability to water depths of 20m to 50m, short offshore construction periods, and minimal impact on offshore operating windows. These foundations consist of an upper jacket and three lower suction piles. The jacket structure stands 92m to 98m tall and weighs 2,300t to 2,600t.

[0004] Currently, there are two common traditional methods for constructing three-pile suction tube jacket wind turbine foundations: First, the upper jacket is constructed horizontally, then turned over and joined to the suction tube using a crane. This requires an ultra-large gantry crane (with a lifting capacity greater than 3,000 tons and a lifting height greater than 120 meters). Second, the upper jacket is constructed horizontally in stages, requiring cranes (with a lifting capacity greater than 1,000 tons and a lifting height greater than 120 meters), followed by staged vertical joining. The disadvantage of method one is that the horizontal construction and overall turning require ultra-large cranes, resulting in significant equipment investment for the construction unit. The disadvantage of method two is that the staged vertical joining is difficult and requires high docking precision. Furthermore, the staged vertical joining involves numerous high-altitude operations, resulting in high safety risks and low efficiency. It can be seen that the use of these two construction processes either requires large equipment investment or the splicing process is difficult and involves many high-altitude operations, which is not conducive to reducing the construction cost of the three-pile suction tube jacket wind turbine foundation and improving the construction efficiency. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an offshore wind power suction tube jacket installation method and device, which solves the problems of traditional three-pile suction tube jacket construction process and large equipment investment, difficult splicing process and many high-altitude operations.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a method for installing a suction tube jacket, which specifically includes the following steps:

[0007] S1. Preset a first hanging point at one end of the lying jacket body in the horizontal direction, and preset a second hanging point at the other end of the lying jacket body in the horizontal direction, and set the line connecting the first hanging point and the second hanging point as the initial line;

[0008] S2, vertically hoisting the first hanging point upward at a first hoisting speed, and vertically hoisting the second hanging point upward at a second hoisting speed, while adjusting the horizontal distance between the first hanging point and the second hanging point to gradually decrease until the line connecting the first hanging point and the second hanging point rotates 90 degrees relative to the initial line;

[0009] S3. After synchronously lifting the first lifting point and the second lifting point vertically upward to a preset installation height at a third lifting speed, the suction cylinder body is installed vertically below the jacket body.

[0010] The present invention also provides a suction tube jacket installation device for connecting a suction tube body and a jacket body, comprising a first lifting tower and a second lifting tower;

[0011] The first lifting tower is used to hoist one end of the jacket body, and the second lifting tower is used to hoist the other end of the jacket body. The lifting height of the first lifting tower is greater than the lifting height of the second lifting tower. The difference in lifting height between the first lifting tower and the second lifting tower is greater than or equal to the vertical height of one jacket body. The lifting height of the second lifting tower is greater than the vertical height of one suction cylinder body. The horizontal spacing between the first lifting tower and the second lifting tower is adjustable.

[0012] The beneficial effects of the present invention are as follows: the present invention provides an offshore wind power suction tube jacket installation method and device, wherein lifting points are respectively set at the opposite ends of the lying jacket body, and the jacket body is flipped into an upright state by controlling the lifting speed of each lifting point, thereby facilitating the installation of the suction tube body and the jacket body. After the two are installed, they can be directly transported vertically, solving the problems of the traditional three-pile suction tube jacket construction process and large equipment investment, difficult splicing process and many high-altitude operations.

Finally, the two lifting points are lifted upward at the same speed, and finally, the suction cylinder body is installed vertically below the jacket body. The present invention adopts a method of horizontally constructing the upper jacket and then turning it over, lifting, and splicing it as a whole, achieving horizontal construction of the upper jacket, improving construction accuracy and efficiency, and reducing the risks of high-altitude operations during the turning, lifting, and splicing process.

[0050] An offshore wind power suction tube jacket installation device is used to connect a suction tube body and a jacket body, comprising a first lifting tower and a second lifting tower;

[0051] The first lifting tower is used to hoist one end of the jacket body, and the second lifting tower is used to hoist the other end of the jacket body. The lifting height of the first lifting tower is greater than the lifting height of the second lifting tower. The difference in lifting height between the first lifting tower and the second lifting tower is greater than or equal to the vertical height of one jacket body. The lifting height of the second lifting tower is greater than the vertical height of one suction cylinder body. The horizontal spacing between the first lifting tower and the second lifting tower is adjustable.

Both the first and second lifting towers are equipped with lifting assemblies, which are used to lift the jacket body, offering easy control and low cost. This design allows the three lifting assemblies to form an isosceles triangle, ensuring stability and precision during lifting operations. A concrete base is placed on the ground, providing support and stability. The tower body is mounted atop this concrete base, providing a stable structure and easy installation. The tower body consists of a base section, a standard section, a top section, and a beam. The base, standard, and top sections can be selected based on the required construction height.
