Embodiment 1

[0022] like figure 1 As shown, the hydraulic cabin 9 is connected to the seabed by anchor chains 6 with high holding power; the middle position of the hydraulic cabin 9 is installed with a bidirectional turbine generator 5 with a shroud; both ends of the hydraulic cabin 9 are connected to a hydraulic cylinder 4, and a brake block 8 is installed at the connecting position; there is a piston 3 in the hydraulic cylinder 4, and the piston is connected with the floats 1 and 2 through the connecting rod 7; the float is divided into a front float 1 and a rear float 2, which are located in the hydraulic chamber 9. upper space at both ends.

[0023] like figure 2 As shown, the peak is at the front float 1; the trough is at the rear float 2.

[0024] like image 3 As shown, the trough is at the front float 1; the crest is at the rear float 2.

[0025] The working principle of this embodiment:

[0026] In actual use, the front float 1 and the rear float 2 are in a floating state, a...

Embodiment 2

[0028] see figure 1 and Figure 4 , the only difference from Embodiment 1 is that the main body of the wave energy conversion device is not fixed on the seabed with anchor chains, but is directly fixed on the seabed foundation.

Abstract

The invention belongs to the fields of renewable energy technology and marine devices, particularly relates to a U-shaped tube type wave power generation device adopting double floaters. The U-shaped tube type wave power generation device comprises the floaters, pistons, connecting rods, a turbine generator, hydraulic cylinders and anchor chains. The floaters are respectively connected with the pistons through the connecting rods. The pistons are respectively arranged at the two ends of the hydraulic cylinders. The two-way turbine generator is arranged in the middle of the hydraulic cylinder. The U-shaped tube type wave power generation device is characterized in that the floaters move up and down along changes of water level of a sea surface to drive the pistons in the hydraulic cylinders to move, thus liquid in a hydraulic cabin flows to drive the two-way turbine generator to generate power. By the changes of the water level of the sea surface along waves, wave energy is efficiently converted into hydraulic energy and further converted into electric energy to provide electric power for offshore facilities such as a sea lantern and an observation station. The U-shaped tube type wave power generation device is high in reliability and easy to produce, mount and move.

Description

technical field [0001] The invention belongs to the field of novel renewable energy technology and marine equipment, in particular to a U-shaped tubular wave energy generating device using double floating bodies. Background technique [0002] With the development of the world economy, the increase of population and the continuous improvement of social living standards, the demand for energy in various countries has increased rapidly. In recent years, driven by the depletion of fossil energy, the security of energy supply and the protection of the environment, the marine energy industry, one of the main renewable energy sources, has made great progress, and the application technology of marine energy is becoming more and more mature. Shows a bright future. At present, the main wave energy devices in the world can be divided into three categories according to their basic principles of power generation: oscillating water column type, oscillating float type and over-wave type. ...
