Abstract

The invention belongs to the field of utilization of renewable energy, and provides a wave-energy generating device for generating power through water potential energy. The device comprises a water absorbing tank, a water storing tank, a water absorbing pipe, a water draining pipe, a piston, a sealing ring, a floating block, a hinge pin, a supporting platform, and a water draining port in the upper part of the water absorbing tank. The device is characterized by further comprising a pressing rod, a turbine generating device in the water absorbing pipe, a turbine generating device in the water draining port, a baffle switch hinged to the piston, a baffle switch hinged to the water absorbing port, a filtering net and a water pipe fixing rack, wherein the pressing rod and a rack achieve a lever effect, and the floating force and gravity effect of the wave to the floating block can be amplified to act to the piston. According to the water-energy generating device, the pressing rod can drive the piston to reciprocate, and the baffle switch hinged to the piston and the baffle switch hinged to the water absorbing port play supporting roles, so as to achieve the purposes of absorbing water and draining water; meanwhile, the turbine generating devices in the water absorbing pipe and the water draining port of the water storing tank are correspondingly driven to generate power during the water absorbing process and the water draining process; array manners are combined to use, so that the wave energy can be utilized well, and the purpose of continuously generating power can be achieved. The device is of an opening structure, is influenced a little by the environment, and is simple in structure, and convenient to maintain and replace a part.

Description

technical field [0001] The invention belongs to the field of renewable energy utilization, and relates to a wave energy generating device for generating electricity by using seawater potential energy. Background technique [0002] Compared with other marine energy sources, wave energy has the advantages of wide distribution, high energy flow density, and easy conversion of energy forms. It attracts skilled craftsmen from all over the world and tries to convert it for human use. The existing wave energy conversion devices are mainly wave energy storage type, valve type, point absorption type, pendulum type and so on. The types of wave energy generating devices that have been put into use are mainly wave-condensing and valve-type. The Chinese patent with the patent number CN200710124322.7 proposes a device for converting wave energy into potential energy of seawater. It is pressed into the high-level water reservoir by a closed hydraulic cylinder. Its float is directly conn...
