Oscillating water column type wave energy power generation equipment combined with single-pile type offshore wind turbine and power generation method

Abstract

The invention discloses oscillating water column type wave energy power generation equipment combined with a single-pile type offshore wind turbine and a power generation method. Four equal-altitude oval holes are formed in the positions, below the sea level, of a hollow pile of the offshore wind turbine in a uniformly-spaced mode, and long axes of the oval holes are in the vertical direction; ventilation openings are formed in the positions, above the sea level, of the hollow pile of the offshore wind turbine, and thus air chambers are formed in the positions, located between the ventilationopenings and the oval holes,of the hollow pile; two opposite hemispheric flow guiding covers are arranged on the inner walls of the air chambers; a turbine is vertically arranged in a gap between thetwo flow guiding covers; and a subulate gear group is formed by a subulate gear fixedly connected with a horizontal shaft and a subulate gear fixedly connected with a vertical shaft, the horizontal shaft of the subulate gear group is connected with a power input shaft of an electric generator placed on a horizontal platform through a coupler in a transmission mode. According to the oscillating water column type wave energy power generation equipment, the offshore wind turbine is directly inserted and fixed into seabed through the hollow pile, and one segment of the hollow pile is arranged as the air chambers of the oscillating water column type wave energy power generation equipment, thus wind energy is captured, and wave energy can be utilized effectively at the same time, and the overallgenerating capacity is increased, a pile and transmission cable can be shared, and the investment is saved.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of offshore wind energy and wave energy, and in particular relates to an oscillating water column wave energy generating device combined with a single-pile offshore fan and a generating method thereof in the field. Background technique [0002] Energy is an important material basis for human survival. In today's world, fossil fuel energy is being exhausted, and the development and utilization of renewable energy has become an inevitable trend of development. Among various types of marine renewable energy, offshore wind energy technology is the most mature. In addition to the extremely rich resources, compared with onshore wind energy, offshore wind energy also has high wind speed, strong wind force, few calm wind periods, and low turbulence. qualitative features. At present, offshore wind energy development mainly adopts 3-5MW high-power wind turbines, and the future development direction...

AI Technical Summary

Problems solved by technology

Among them, the oscillating water column wave energy generation device has the characteristics of simple structure, no underwater moving parts, high safety and reliability, etc., but due to the high cost of the air chamber, the output value is reduced and the development is limited.

In addition, my country's waves have the characteristics of short cycle, small wave height, and low energy flow density. It is difficult for a single wave energy power generation device to achieve good power generation effect, and the cost is expensive.
