Wave energy acquisition device

Abstract

The invention discloses a wave energy acquisition device comprising a foundation pillar (1), a first floater (5), an oil tank (11), an actuating mechanism (12), a floating sleeve (2) in sliding fit with the foundation pillar (1) and two first wave energy acquisition devices (9) capable of simultaneously acquiring wave energy in the horizontal direction and the vertical direction, wherein one ends of the first wave energy acquisition devices (9) are fixed on the floating sleeve (2), and the other ends of the first wave energy acquisition devices (9) are hinged on the first floater (5); and oil inlets of the first wave energy acquisition devices (9) are communicated with the oil tank (11), and oil outlets of the first wave energy acquisition devices (9) are communicated with an oil inlet of the actuating mechanism (12). The wave energy acquisition device can be used for acquiring the wave energy in the horizontal direction and the vertical direction and is simple in structure.

Description

technical field [0001] The invention belongs to the field of renewable energy power generation, and in particular relates to a wave energy capture device. Background technique [0002] The wave energy capture device converts wave energy into controllable mechanical energy or hydraulic energy through mechanical or hydraulic devices and systems, and then generates electricity or drives actuators such as hydraulic motors to rotate. A buoyant pendulum type wave energy capture device in the prior art, the lower end of the device is fixed, the upper end can swing an angle under the action of wave energy, and the actuator is driven by angular oscillation. This device can capture wave energy in the horizontal direction ;Another oscillating float type ocean wave power generation device includes an oscillating floating body and a vibrating mechanism placed in the oscillating floating body, a mechanical transmission mechanism and a generator. The upper end of the spring is fixed on th...

Problems solved by technology

The disadvantages of the wave energy capture devices in the prior art are: most of the wave energy capture devices in the prior art can only capture wave energy in one of the horizontal or vertical directions; there are also few wave energy capture devices in the prior art that can simultaneously Capture wave energy in both horizontal and vertical directions, such as a "nodding duck" type wave energy capture device, including fixed indirect conversion device, fixed direct conversion device, floating direct conversion device and floating indirect conversion device, The movement of the wave incident wave makes the dynamic pressure push the rotating part to rotate around the axis, and the change of the hydrostatic pressure makes the floating part move up and down. Converted to electrical energy; its disadvantage is that the structure is complex
