Upper and lower double-layer capsule structure wave energy harvesting device

Abstract

The invention relates to a wave energy acquisition device of wave energy generating equipment. The device is of a snakelike bag structure; a main floating body can be deformed along with the fluctuation of wave; two bags are arranged in the main floating body and distributed on the upper and lower parts of the floating body; the upper and lower bags are connected through a pipeline; and a generator device is connected between the two pipelines. When the floating body floats up and down along with wave, deformation is generated; the wave peak ensures that the upper bag body generates negative pressure relative to the lower bag body; and the wave trough ensures that the lower bag body generates negative pressure relative to the upper bag body. As a result of pressure difference, liquid flow is generated between the bag bodies, and the liquid flows through the generator to drive the generator to move, so that electric energy is generated. By adopting the device, wave energy can be utilized efficiently. Besides, the device is strong in adaptability. A proper length of the bag body can be designed according to the wavelength of sea wave in different sea areas, so that the maximum energy utilization rate is achieved. The device is suitable for industrial power generation, is simple in production and low in cost, and has high application value.

Description

technical field [0001] The invention relates to an energy collection part of a hydraulic wave generator for wave power generation. Background technique [0002] In recent years, with the depletion of fossil energy, various new energy sources have attracted much attention, and wave energy, as one of the main forms of marine energy, has received various developments and has been used in many applications such as special-purpose Low-power wave energy power generation has been popularized and applied in navigation light buoys, light poles, lighthouses, etc. In remote islands, small-scale wave power generation can already compete with diesel generator set power generation. But the cost of large-scale wave power generation is still difficult to compete with conventional energy generation. The invention focuses on improving the collection efficiency of wave energy and increasing the energy acquisition rate, thereby reducing costs and making large-scale wave energy generators poss...
