Embodiment Construction

[0027] refer to figure 1 , figure 2 , in order to adopt a water surface wave energy recovery device of the present invention, which is suitable for recovering and converting ocean surface wave energy into electrical energy. The device mainly includes: an upper float body 1 and a lower float body 2 fixedly connected.

[0028] The lower float body 2 is a slender structure, and its bottom is fixed with a counterweight body 3, so that the device can maintain an upright posture in the water; the quality of the counterweight body 3 should make the upper and lower float bodies 1 and 2 float on the water surface as a whole, and make the device The horizontal plane submerges about a quarter of the upper float body 1; the lower part of the counterweight body 3 is provided with an iron anchor, and the iron anchor and the counterweight body 3 are connected by a cable 4, which is used to fix the device at a selected position and prevent it from drifting with the waves. Leave.

Abstract

The invention belongs to the technical field of renewable energy, and discloses a water surface wave fluctuation energy recovery device, being suitable for recycling and converting ocean surface wavefluctuation energy into electrical energy. The water surface wave fluctuation energy recovery device comprises a lower float body and an upper float body which are fixedly connected, wherein the lowerfloat body is provided with a counter weight body and an anchor; and the upper float body is a cavity body, which is characterized in that a wave fluctuation energy recovery unit is arranged in the cavity body, the wave fluctuation energy recovery unit contains an induction coil, an induction coil bracket, a plate spring, a plate spring bracket and a magnet, wherein one end of the plate spring isfixed on the plate spring bracket, and the other end thereof is fixed with the magnet; the magnet does oscillating traverse motion vertical to the axis of the induction coil under the action of watersurface wave; the induction coil moves corresponding to the magnet so as to cut magnetic line of force to generate electricity.

Description

technical field [0001] The invention belongs to the technical field of renewable energy, and in particular relates to a water surface wave energy recovery device, which is suitable for recovering and converting ocean surface wave energy into electric energy. Background technique [0002] For a long time, the massive use of fossil energy such as petroleum and coal has not only caused the depletion of the above-mentioned resources, but also caused many serious problems such as global warming and environmental pollution. In order to solve energy shortages, global warming and increasingly serious environmental problems, in recent years, governments around the world have attached great importance to renewable energy and invested a lot of money in the research and development of related theories and technologies. [0003] Ocean wave power generation is one of the important research directions in the field of renewable energy technology. Ocean wave power generation uses specific d...
