Embodiment Construction

[0031] Such as figure 1 , figure 2 with image 3 As shown, the overall installation and construction method of the offshore wind power generating set of the present invention mainly includes three stages of wind turbine loading, wind turbine towing, and wind turbine installation:

[0032] Wind turbine loading stage: first, the wind turbine is assembled on land at the front of the wharf (a pier with the same size as the wind turbine foundation platform should be added at the front of the wharf), the hydraulic outrigger 12 of the truss on the barge is retracted, and the front half of the main girder is lifted by a column crane, leaving out of the installation position, the balance fixture is opened, the suspension hydraulic cylinder floats, and the pressure of the hydraulic system only offsets the gravity of the main girder at the bottom; the barge is close to the pier, so that the rear half keyway of the main girder is docked with the fan flange key, and the crane rotates to ...

Abstract

The invention discloses a construction method and equipment for integrally mounting an offshore wind generating set. The construction method comprises three phases of loading, towing and mounting the fan. The equipment for integrally mounting the offshore wind generating set and consists of a barge and a fixed device on the barge, wherein the main body of the fixed device is a truss; a balance clamp is arranged at the top of the truss; a hydraulic cylinder hanging system is arranged in the middle of the truss; a U-shaped groove is arranged at the front end of the barge; a girder is arranged in the middle of the U-shaped groove; two ends of the girder are fixed on the barge; and an open hole with the size being the same as the diameter of a tower column at the bottom of the fan is arranged in the middle of the girder. In the construction method for integrally mounting the offshore wind generating set, a large-sized special floating crane and special equipment can be omitted; the construction method has simple process and low cost and can ensure the mounting requirement and regulation of the offshore wind generating set; and the equipment for integrally mounting the offshore wind generating set has simple structure and is convenient for operation.

Description

technical field [0001] The invention relates to an overall installation and construction method of an offshore wind power generating set and equipment thereof. Background technique [0002] At present, there are mainly two methods for the installation and construction of offshore wind turbines. One is to use large floating cranes for direct overall hoisting, and the other is to use large-scale equipment dedicated to wind turbine installation. The former requires large-scale special floating cranes, and auxiliary equipment needs to be installed on the bottom and middle of the wind turbine, which is difficult to construct, with high risks and high costs; the latter has complex equipment, high cost, and long construction period. Contents of the invention [0003] One object of the present invention is to provide an overall installation and construction method for offshore wind turbines that does not require an operating platform in the sea, does not require large-scale specia...
