Problems solved by technology

[0004] (1) The inclination of the foundation will cause problems such as excessive wear and tear of the generator set. Therefore, relevant domestic and foreign regulations have strict control standards for the inclination of the foundation of offshore wind turbines. For the barrel foundation of offshore wind turbines, the foundation inclination control is a construction problem
[0005] (2) The sea transportation of the foundation of offshore wind turbines often requires a special large barge, which is expensive, and the lifting process is cumbersome and complicated

Embodiment Construction

[0029] Such as figure 1 As shown, the barrel foundation of the present invention includes a barrel skirt 1, a barrel cover 2 and a connecting cylinder 3 fixedly connected together from bottom to top in sequence, and a spraying device is installed on the bottom of the barrel skirt 2, and the nozzle 11 of the spraying device is fixedly installed on the The bottom end face of the barrel skirt 2. A horizontal displacement sensor 9 is installed on the guardrail 5 at the top of the connecting cylinder 3 to monitor the inclination of the barrel foundation during sinking, and a vertical displacement sensor 10 on the side wall of the connecting cylinder 3 is used to monitor the inclination of the barrel foundation. The vertical sinking displacement during the sinking process. In the cavity of the connecting cylinder 3, a connecting cylinder top plate 14 is fixedly installed, and the connecting cylinder top plate 14 can be installed on the top of the connecting cylinder 3 or at an appr...

Abstract

The invention discloses a self-balancing suction penetration bucket foundation of an offshore wind power generating set and a construction method thereof. The bucket foundation comprises a skirt-shaped part of the bucket, a bucket cover and a connecting cylinder which are fixedly connected with each other sequentially from the bottom to the top, wherein a nozzle is fixedly arranged on the end face at the bottom of the skirt-shaped part of the bucket; a displacement sensor is fixedly arranged on the connecting cylinder; and a connecting cylinder top plate is arranged in the connecting cylinder. The bucket foundation of the invention has self-balancing and anti-inclining functions during the suction penetration. Through hermetically fixing a sleeve on the bucket cover and using the space which is formed by the sleeve, the bucket cover and the connecting cylinder, the bucket foundation can float on the sea surface and perform towage transportation without a special barge so that the marine transportation and the suction penetration construction process are simple and the cost thereof is low.

Description

technical field [0001] The invention relates to a bucket foundation of an offshore wind turbine and a construction method thereof. Background technique [0002] The barrel-shaped foundation in the prior art is composed of a barrel skirt, a barrel cover and a connecting cylinder that are fixedly connected together sequentially from bottom to top. [0003] Tilt control during construction is currently one of the biggest difficulties in the construction of barrel foundations for offshore wind turbines: [0004] (1) The inclination of the foundation will cause problems such as excessive wear and tear of the generator set. Therefore, relevant domestic and foreign regulations have strict control standards for the inclination of the foundation of offshore wind turbines. For the barrel foundation of offshore wind turbines, the foundation inclination control is a construction problem. [0005] (2) The marine transportation of the offshore wind turbine foundation often requires a sp...
