Wave and Tidal Energy Harvesting Devices

Abstract

The invention discloses a wave energy and tide energy acquisition set comprising a base (1), a mounting rack (2), a float (3) and a telescopic cylinder (4). The mounting rack (2) is fixed on the base (1). A cylinder block of the telescopic cylinder (4) is hinged to the mounting rack (2). A piston rod of the telescopic cylinder (4) is hinged to the float (3). The cylinder block of the telescopic cylinder (4) is provided with a first one-way valve (4.1) allowing gas to enter the cylinder block from outside only and a gas outlet (4.2). The wave energy and tide energy acquisition set is characterized in that a tide energy collector (5) is disposed at the lower end of the float (3) and is fixed to the float (3) trough a plurality of connecting rods (6). The wave energy and tide energy acquisition set is capable of acquiring vertical wave energy and horizontal tide energy and is high in utilization efficiency.

Description

technical field [0001] The invention relates to the technical field of development and conversion of ocean energy, in particular to a device for capturing wave energy and tidal current energy. Background technique [0002] With the rapid development of modernization, the development and utilization of green new energy has become an important part of sustainable development, and the ocean occupies 71% of the total area of ​​the earth, which will become an important source of renewable energy utilization in the future. In the prior art, the development of marine new energy is mainly to convert wave energy and / or tidal current energy into controllable mechanical energy and / or hydraulic energy through mechanical or hydraulic devices, so as to supply actuators. For example, the invention patent with the authorized announcement number CN 102562424 B - wave energy capture device, which simultaneously completes the capture of ocean energy in the horizontal direction and vertical dir...

Problems solved by technology

For example, the invention patent with the authorized announcement number CN 102562424 B - wave energy capture device, which simultaneously completes the capture of ocean energy in the horizontal direction and vertical direction through the swing hydraulic cylinder and the telescopic hydraulic cylinder, but in this prior art, its telescopic When the hydraulic cylinder is subjected to a horizontal force in a single direction, it can only complete one extension or compression. That is to say, the above-mentioned wave energy capture device in the prior art can only complete the tidal current energy in the horizontal flow direction during the flow direction alternation process. A piston movement, so its utilization rate of tidal current energy in the horizontal direction is very low
