Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention is described in detail:

[0023] Such as figure 1 , figure 2 As shown, the offshore floating platform 1 is a plate structure with a rectangular opening in the middle, so that the bottom plate 3 is inserted in the middle of the floating platform through a clamping device; the bottom plate 3 is connected with four folding connecting rods by bolts; the The four connecting rods 4 are respectively located around the bottom plate 3 at a certain distance, and their top ends are connected to the protective shell 7 of the power generating device by bolts. Each section (4-1) in each of the connecting rods 4 is fixedly connected with the next section (4-2) through a peripheral locking mechanism (11). The offshore floating platform 1 is connected to the shallow buried foundation on the seabed through four anchor chains 5, one end of the anchor chain 5 is connected to the link 2 of the offshore floating platfor...

Abstract

The invention discloses a folding vortex-induced vibration tidal current energy power-generation device. The folding vortex-induced vibration tidal current energy power-generation device comprises an offshore floating platform and anchor chains. The offshore floating platform is connected with a set of folding connecting rods through bolts. A protective shell is connected to the top end of each connecting rod. A power generation mechanism and a swing mechanism provided with a swing rod are arranged in each protective shell. The swing mechanisms are hinged to the bottoms of the interiors of the protective shells through universal bases. The swing rods penetrate through sealing mechanisms to stretch out of the protective shells. Foldable masts are connected to the tops of the swing rods. The two sides of each swing rod are symmetrically provided with the corresponding power generation mechanisms. The power generation mechanisms are connected with the bottoms of the interiors of the protective shells through rechargeable batteries. According to the folding vortex-induced vibration tidal current energy power-generation device, by utilizing the advantages of vortex-induced vibration power generation, power generation efficiency is improved, and daily maintenance cost and damage cost are reduced.

Description

technical field [0001] The invention relates to the field of vortex-induced vibration tidal current energy generation, in particular to a foldable vortex-induced vibration tidal current energy generation device. Background technique [0002] In the face of the world's increasingly tense energy and increasingly serious environmental pollution, the development and utilization of new energy has undoubtedly become an important way to alleviate the energy crisis and improve the living environment. Ocean energy is the largest energy reserve on the earth. It is not only an ideal energy source that does not require fuel, but also causes almost no pollution to the environment. It is a renewable energy source. As we all know, tides are the periodic fluctuations of seawater formed by the gravitational force of the moon and the sun. And the energy it carries—tidal current energy, as a clean and pollution-free renewable energy, has the characteristics of large storage capacity, wide dis...
