Embodiment Construction

[0022] The present invention will be further described below in conjunction with specific examples.

[0023] Such as figure 1 As shown, the present invention includes: a floating body ship 1, several bottom beams 2 laid on the floating body ship 1 by welding, a support column and a suspension device 3 installed on the bottom beam 2 by welding, wherein the floating body ship 1 is It is a square floating body ship structure assembled by several buoyant tanks 4 and reinforced buoyant tanks 5 (six in this embodiment) by means of bolt connection; Arranged at one end of the floating body vessel to ensure that there is enough space for the crane 7 to carry out hoisting operations. The crane lifts the floating body in advance. After removing the fan blade 8, temporarily place the fan blade 8 on the suspension device, and then use the crane to remove the damaged generator and hoist the new generator. Hoist back fan blade 8 again, realize alternator replacement.

Abstract

The invention relates to a structure for replacing a wind driven generator of a reservoir or a lake and a using method thereof. The structure comprises a floating body ship, bottom beams laid on the floating body ship, supporting columns installed on the bottom beams and fan blade suspension devices installed on the supporting columns; the floating body ship is of a square structure formed by assembling a plurality of floating boxes, the supporting columns located on the bottom beams are located on one side of the generator to be replaced and provided with the suspension devices, after the fanblades are dismounted by a crane, the suspension devices are used for temporarily placing the fan blades, then the crane is used for dismounting the damaged generator, and a new generator is hoisted,so that replacement is realized. According to the structure for replacing the wind driven generator of the reservoir or the lake and the using method thereof, the generator is convenient to replace,vulnerable accessories of a fan can be replaced in shallow-water and limited-buoyancy places such as reservoirs or lakes, a second crane used for assisting a first crane in turning over the fan bladesin the air is omitted, other floating bodies (occupying a large amount of space) for placing the horizontal fan blades are also omitted, the construction procedure is simplified, the safety is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to a structure for replacing a generator, in particular to a structure for replacing a wind power generator in a reservoir or a lake and a method for using the same. Background technique [0002] At present, with the rapid development of wind power technology, wind power has become the focus of renewable energy development. For the wind turbines installed on the banks of reservoirs or lakes, some of them have been flooded as the environmental conditions change, and there is also a need to replace components such as generators. However, compared with land wind power, reservoirs or lakes have shallow water, limited buoyancy, and work on the water surface. As a result, conventional technologies and equipment for the replacement of land wind turbine components cannot be used in reservoirs or lakes. Contents of the invention [0003] The main purpose of the present invention is to overcome the above-mentioned shortcoming that prior ...
