Large piston pressurizing type wave energy generation device

Abstract

The invention relates to a wave energy generation device, in particular to a large piston pressurizing type wave energy generation device. The large piston pressurizing type wave energy generation device comprises a generator installed on a water turbine output shaft and a floating body. A water turbine and the generator are located in the floating body, a water inlet is formed in the floating body, and a flow guiding pipe is arranged below the water turbine. A piston sleeve is fixed to the bottom of the floating body, the flow guiding pipe is located in an inner cavity of the piston sleeve, and a center guiding shaft is installed in the piston sleeve. Two limiting devices are installed on the center guiding shaft, and the position, between the two limiting devices, on the center guiding shaft is provided with a piston through a center shaft sleeve. The piston moves up and down along the center guiding shaft under the action of sea waves, and the piston pushes seawater in the inner cavity of the piston sleeve to impact blades of the water turbine in a back and forth mode to rotate to drive the generator to generate power. Due to the structure, the wave energy generation device has the advantages of being simple in structure, low in manufacturing and maintaining cost and capable of improving the utilization rate of wave energy and the reliability of long-term operation.

Description

technical field [0001] The invention relates to a wave energy generating device, in particular to a large-scale piston pressurized wave energy generating device with simple structure, low manufacturing cost and maintenance cost, improved wave energy utilization rate and long-term operation reliability. Background technique [0002] The national economy continues to grow at an annual rate, and correspondingly, this economic growth will inevitably lead to an increase in the demand for energy, especially the increase in demand for electricity. [0003] The existing power generation methods mainly include thermal power, hydropower, nuclear power, etc. Since the development of hydropower and nuclear power will be restricted by many objective conditions, the proportion of the total power generation in the whole society is still relatively small, and thermal power accounts for 80% of China's total power generation. % share. Because thermal power generation needs to consume a large...
