A wave energy hydraulic pump

Abstract

The invention relates to a wave energy hydraulic pump which comprises a plurality of sections of wave energy collection floating bodies, a plurality of hydraulic devices, a plurality of spring oscillator devices and a plurality of water inlet and outlet devices, wherein a rib plate is radially arranged in each section of wave energy collection floating body; each hydraulic device comprises a first hydraulic cylinder, and the first hydraulic cylinder is hinged between two adjacent wave energy collection floating bodies; each spring oscillator device comprises a second hydraulic cylinder, a piston inside the second hydraulic cylinder is connected with one side of a balancing weight on a sliding rod, the sliding rod is horizontally fixed between one rib plate and the rear wall of one wave energy collection floating body, and the other side of the balancing weight is connected with the rear wall of the wave energy collection floating body through a spring on the sliding rod; each water inlet and outlet device comprises a water inlet pipe and a water outlet pipe, one end of the water inlet pipe is communicated with sea water through a filter, and the other end of the water inlet pipe is divided into two paths which are respectively communicated with water inlet holes of one first hydraulic cylinder and one second hydraulic cylinder, and the water outlet pipe of the wave energy hydraulic pump is further divided into two paths which are respectively communicated with water outlet holes of the first hydraulic cylinder and the second hydraulic cylinder. The wave energy hydraulic pump is high in collection efficiency and good in reliability, and can be widely applied to the ocean energy development process.

Description

technical field [0001] The invention relates to a wave energy hydraulic pump, in particular to a high-efficiency wave energy hydraulic pump that utilizes ocean wave energy to drive a piston. Background technique [0002] With the depletion of non-renewable energy sources such as fossils, countries around the world have gradually turned their attention to the ocean. Especially in the 1970s, the upsurge of developing ocean energy gradually started, and in the 21st century, the international community's attention to ocean energy has risen sharply. [0003] As a renewable clean energy, wave energy has a high energy flow density and is the highest grade and most widely distributed energy in ocean energy. It is people's long-term desire to convert inexhaustible wave energy into useful energy, but the instability of wave energy has brought difficulties to the practical application of wave energy. According to the conversion principle of the secondary conversion system, the current...
