Embodiment Construction

[0018] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0019] combine Figure 1~4 , The invention patent includes a power station platform, two tidal current generators and two sets of lifting mechanisms.

[0020] The power station platform mainly includes a vertical floating body 1 , a horizontal floating body 2 and four anchor chains 13 . Longitudinal floating body 1 is elongated, and two ends are provided with anchor chain 13, and upper surface is level with water surface during work, is mainly used for providing buoyancy. The horizontal floating body 2 is relatively wide, and there are installation and maintenance shafts 6 on both sides. The installation and maintenance shaft 6 is a rectangular through groove, the groove width is slightly larger than the diameter of the nacelle shell 8, and the groove length is slightly larger than the total length of the tidal current generator. Installation and maintenance. T...

Abstract

The invention aims at providing a floating-type tidal current energy power station, which comprises a transverse floating body, a longitudinal floating body, tidal current power generators and lifting mechanisms. The longitudinal floating body and the transverse floating body are orthogonally arranged in the shape of a Chinese character 'zhong'. The transverse floating body is overlapped on the longitudinal floating body. An installation and maintenance shaft is arranged on the transverse floating body. Anchoring chains are installed at the two ends of the longitudinal floating body. Each lifting mechanism comprises a lifting column, power boxes and a limiting stopper, wherein the power boxes are installed on the two sides of the installation and maintenance shaft, the limiting stopper is installed between the two power boxes and is connected with the two power boxes and the lifting column is sheathed in the limiting stopper. Each tidal current power generator comprises a cabin shell; and a power generator, a transmission shaft, a speed increaser, blades, a hub and a fairing cap which are installed in the cabin shell and are sequentially connected. The tidal current power generators are respectively connected with the lifting columns. By adopting a power station structure which is of the shape of the Chinese character 'zhong', the tidal current energy power station is guaranteed to have better stability, and the power generation performance of the tidal current power generators is improved; and the structure is simple and the production cost is low.

Description

technical field [0001] The invention relates to a tidal current power generation device. Background technique [0002] The increasing shortage of energy in the world and the continuous deterioration of the environment have prompted countries all over the world to accelerate the development and utilization of green energy. As a green renewable energy, trend energy has the characteristics of high energy density, strong predictability, and abundant reserves. It is becoming more and more popular in the world. countries' attention. [0003] At present, there is no successful commercialization project for large-scale development and utilization of tidal current energy. However, based on a comprehensive assessment of development and utilization site selection, economic technology, and environmental impact, different types of prototype designs have been proposed and tested in the laboratory. , sea areas were experimentally studied. [0004] Various known tidal current energy power...
