[0034] Referring to 3, the present invention further provides a method for installing a tension leg platform, comprising: Step 1: Install multiple tendon balancing devices 2 at the bottom of the tension leg platform 1. Use the above-mentioned suction cylinder automatic installation device 5 for offshore wind power construction to grab multiple suction cylinders 4 one by one to the corresponding anchoring positions on the seabed, and use a suction pump to complete the anchoring of the suction cylinders 4. The specific process is as follows: The tendon balancing device 2 is installed and fixed to the tension leg platform 1 at the dock, and then towed to the designated location by a tugboat.

[0035] The automatic installation device 5 for suction cylinders for offshore wind power construction first selects a corresponding number of suction cylinders 4 according to the required number of tendons 3, and places the suction cylinders 4 on the installation position of the automatic installation device 5 for suction cylinders for offshore wind power construction. Then, the automatic turntable 5020 rotates to drive the cantilever 5021 to rotate to the position corresponding to the suction cup 5011 and any one of the suction cylinders 4, that is, the suction cup 5011 is above the suction cylinder 4. Then, the entire automatic installation device 5 for suction cylinders for offshore wind power construction is hoisted underwater by a large installation ship on the sea surface, and the telescopic support leg 503 is started to adapt to the seabed for landing. The position of the automatic installation device 5 for suction cylinders for offshore wind power construction is adjusted so that the guide port 50213 is directly opposite to the anchoring position of the suction cylinder, the telescopic device 5010 is grabbed and extended, and the suction cup 5011 is started to realize the adsorption of the suction cylinder 4. The upper end of the suction cylinder 4 has a corresponding suction cylinder adsorption portion 401 that cooperates with the suction cup 5011, and the suction cylinder adsorption portion 401 is an upwardly protruding adsorption plane. Then the transverse movement assembly works, driving the grabbing mechanism 501 and the suction cylinder 4 to move above the suction cylinder anchoring position, the grabbing mechanism 501 releases the suction cylinder 4, and the suction cylinder 4 falls into the seabed through the guide port 50213, the suction pump 400 of the suction cylinder 4 works, and the suction cylinder 4 slowly moves downward until it is completely fixed to the seabed, the transverse movement assembly drives the grabbing mechanism 501 to return to the initial point in the opposite direction, and the automatic turntable 5020 drives the cantilever 5021 to rotate above the No. 2 suction cylinder anchoring position to repeat the above process, and all the suction cylinders 4 are installed. When the suction cylinder automatic installation device 5 for offshore wind power construction rotates the cantilever 5021, it can not only align the guide port 50213 with the next suction cylinder anchoring position, but also align the grabbing mechanism 501 with the next suction cylinder 4 on the disc, without the need to control the rotation of the cantilever 5021 and the rotation of the suction cylinder 4 respectively through two mechanisms, so the structure is simpler and the operation is more convenient.

[0036] Step 2, after installing the suction cylinder 4, the automatic suction cylinder installation device 5 for offshore wind power construction is recovered, and then the tension leg platform 1 is towed to the sea surface above the anchoring position by a tugboat.

[0037] Step 3, connecting the tension leg platform 1 to the tendon 3 through the tendon balancing device 2.

[0038] Among them, the overall structure composed of the tension leg platform 1, tendons 3, and suction cylinders 4 is introduced: a plurality of tendons 3 are arranged around the lower end of the tension leg platform 1, and the number of tendons 3 is the same as that of suction cylinders 4.

[0040] Continue reading Figure 4 and Figure 5 In one embodiment of the present invention, the driving component is engaged with the toothed plate through the gear 202, and the driving component drives the gear 202 to rotate, and then drives the toothed plate to move through the gear 202.

[0041] Specifically, the drive assembly includes a housing 203 and an electric worm gear mechanism, the housing 203 is sleeved on the telescopic movable part 201, and the housing 203 is fixedly connected to the telescopic fixed part 200 (not shown in the drawings), so that the telescopic movable part 201 can move up and down in the housing 203, and the electric worm gear mechanism is a known structure, which includes a motor 204, a worm wheel 205 and a worm 206, the worm wheel 205 and the worm 206 are rotatably installed inside the housing 203, the motor 204 is connected to the worm 206, the worm wheel 205 is meshed with the worm 206, the worm wheel 205 is also connected to the wheel shaft of the gear 202, and the worm gear mechanism drives the gear 202 to rotate. The above-mentioned drive assembly is waterproofed in a known manner.

[0042] When the tendon balancing device 2 is working, the telescopic movable part 201 is driven to move up and down through the worm gear mechanism, thereby driving the tension on the tendon 3 to optimize the balance of the entire tension leg platform 1.

[0043] It should be noted that all the electric control structures that enter the water in the present invention are waterproofed in a known manner.
