Embodiment Construction
[0022] The present invention will be further described below in conjunction with accompanying drawing and embodiment:
[0023] figure 2 The structure of the wave energy conversion device according to the first embodiment of the present invention is shown. Such as figure 2 As shown, the wave energy conversion device is mainly composed of a first driving floating body 100 floating on the water surface, a piston pump 300 placed in the water, and a weight 400 sunk at the bottom for fixing the piston pump 300 . The piston pump 300 is a reciprocating piston pump with single-piston bidirectional action, and is vertically arranged in the water body below the first driving floating body 100 . The pump body 301 of the piston pump 300 is divided into upper and lower working chambers by a piston 302 . The upper working chamber 303 is a closed space, and is provided with a water inlet check valve 305 and a water outlet check valve 306 at its upper end. The bottom of the lower working...

The invention discloses a wave energy conversion device. The device comprises a first drive floating body floating on a water surface, a piston pump which is arranged below the first drive floating body in water, and a heavy object which is sunk at a water bottom, wherein the top of the piston pump is provide with a second floating body; the bottom of the piston pump is tied on the heavy object at the water bottom through a rope; and the upper end of a piston of the piston pump is connected with the bottom of the first drive floating body through a first traction rope, and the lower end of the piston of the piston pump is connected with a counter weight through a second traction rope, so that the piston moves upward along with the first drive floating body, and is pulled by the counter weight to move downward when the first drive floating body moves downward, so that reciprocating motion is realized to discharge high-pressure water flow. The invention also discloses a wave energy conversion system which formed by connecting a plurality of sets of wave energy conversion devices in parallel; and the system has the advantages of simple structure, low manufacturing cost, and strong emergency shielding table operability and cannot be damaged by wind waves.
Description
technical field [0001] The present invention relates to an energy conversion device, more specifically, to a wave energy conversion device and a wave energy conversion system. Background technique [0002] Nearly 70% of the earth's area is water, and there are huge waves in oceans and large lakes, and these waves contain huge energy. In today's energy shortage, how to effectively utilize these inexhaustible renewable clean energy has become the focus of everyone's attention, and various solutions for converting wave energy have also been provided. [0003] The Chinese patent "Wave Energy Conversion System" with application number 200810068359.7 and authorized announcement number CN101624960B discloses a wave energy conversion system that effectively converts wave energy into potential energy for power generation or transports water to high ground. Such as figure 1 As shown, the system suspends a frame 30 with a large area and spanning multiple wave cycles in the water, and...
