A self-priming gravity wave pump

Abstract

The invention discloses a self-priming gravity wave pump. The pump body adopted is a sealed cylinder, and two water holes symmetrical along the central axis are respectively opened at the upper and lower ends of the pump body. The upper and lower two holes on the same side of the pump body The two water holes are connected by pipelines as the water inlet pipeline and the water outlet pipeline respectively. The two water holes at the lower end are connected with the outside, and a check valve is set in the pipeline at the water hole; the floating body on the water surface is rigidly connected to the counterweight. ;The upper end of the piston rod is fixedly connected with the counterweight, and the lower end is fixedly connected with the piston; the piston rod extends into the pump body through the upper end surface of the pump body, and the piston rod is in sealing contact with the upper end surface of the pump body; the bottom of the pump body is fixedly connected with the support buoy , the supporting buoy is filled with air; the underwater floating body is fixedly sleeved on the upper end of the supporting buoy; the lower end of the supporting buoy is connected to the anchor through a anchor chain. The wave pump uses wave buoyancy and its own gravity to push the piston to move up and down.

Description

technical field [0001] The invention belongs to the technical field of wave energy power generation, and is mainly applied to providing green power in sea islands and coastal areas. Background technique [0002] Wave energy power generation is to convert the wave energy into reciprocating mechanical energy through the wave energy device, and then convert it into the required power or electric energy through the power intake system. At present, the main forms of wave energy power generation devices are oscillating water column type, surfing wave type and oscillating float type. The oscillating water column device is difficult to construct and maintain due to the influence of the terrain; the over-the-wave device is too large, and the cost and maintenance cost are high; the oscillating buoy device has many structural components and the anchoring system is more complicated. Contents of the invention [0003] In view of this, the present invention provides a self-priming grav...
