Embodiment Construction

[0026] Such as Figure 1 to Figure 11 As shown, a tension membrane type wave energy generating device of the present invention includes a tension membrane 11 , a tension spring 12 , a gasket 13 , a strong magnet 14 , a linear generator 2 , and an underframe 3 . Tension film 11 is provided with tension film round holes 111 along the outer edge of both sides in the width direction, and the arc-shaped hook at one end of extension spring 12 passes through gasket 13 and the round holes 111 on the edge of tension film 11 to keep connected with tension film 11 successively. The arc-shaped hook at the other end of the extension spring 12 is kept connected with the round hole 31 of the bottom frame 3 in the floating module. The gasket 13 is an annular metal gasket fixed on the upper and lower surfaces of the tension membrane 11 . The strong magnet 14 is divided into an upper part 141 and a lower part 143 , wherein the lower end surface of the lower part has a screw hole 142 inwardly at...

Abstract

The invention discloses a tension force film type wave energy power generation device. The power generation device comprises a base frame. Support rods are installed on two ends of the base frame. Cross bars are installed on the support rods. A tension force film is arranged between the cross bars and connected with the cross bars through an elastic device. The lower parts of the cross bars are connected with multiple linear generators. When the tension force film is subjected to wave movement affects, all parts are deformed at different degrees to drive the linear generators to generate power. According to the invention, by use of the cylindrical permanent magnet linear generators, the size and the weight of the power generation device are reduced, and the structure is quite compact, so compared with a traditional wave energy conversion device, the power generation device is quite economical and convenient in power supply of oversea floating body structure bodies, and compared with the current solar power supply, the power generation device has quite high capturing efficiency and generates power all the time.

Description

technical field [0001] The invention relates to a tension membrane type wave energy power generation device, which belongs to the field of power generation. Background technique [0002] With the increasing human demand for resources, the consumption of non-renewable resources such as oil, coal, and natural gas is accelerating. For the sustainable development of human beings, the research and utilization of renewable resources is imminent. Ocean energy has the highest energy density in the field of renewable energy, including wave energy, tidal energy, ocean current energy, seawater temperature difference energy, seawater salinity difference energy, etc. Technological progress has also made the use of ocean energy possible. [0003] Among them, wave energy, as a kind of ocean energy, has huge utilization advantages. First of all, ocean wave energy has the least impact on the environment during the development process and exists in the form of mechanical energy, which is th...
