Floating type wave energy power generation device by using piston to pressurize water turbine to generate electricity

Abstract

The invention relates to wave energy power generation devices, and provides a floating type wave energy power generation device by using a piston to pressurize water turbine to generate electricity. The floating type wave energy power generation device comprises an electric generator mounted in a floating body, the water turbine and a piston pressurization system, wherein the water turbine and the piston pressurization system are connected to the lower portion of the floating body. The water turbine is placed in a water channel in the top of a piston sleeve, and is connected with the electric generator through an energy output shaft. A center guide shaft is mounted in the piston sleeve, two limiting devices are mounted on the center guide shaft, and the piston is mounted on the center guide shaft between the two limiting devices through the center shaft sleeve. The piston moves up and down along the center guide shaft under the action force of waves, the piston pushes seawater in an inner cavity in the piston sleeve to flow through the water channel to repeatedly impact vanes of the water turbine to rotate, and the electric generator is driven to generate electricity. Due to the structure, the wave energy power generation device has the advantages that the structure is simple, the manufacturing cost and the maintaining cost are low, and the wave energy utilization rate and the long-term operation reliability are improved.

Description

technical field [0001] The invention relates to a wave energy generating device, in particular to a wave energy generating device with simple structure, low manufacturing cost and maintenance cost, high wave energy utilization rate and long-term operation reliability. technical background [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 amount of fossil fuels and emit a ...
