Problems solved by technology

[0003] The current wave power generation devices mainly include oscillating water column type, pendulum type, oscillating float type, etc. The main problems of these power generation devices are that the energy conversion and transmission mechanism are subjected to a relatively large impact force, and the obtained energy is discontinuous and poor in stability. The transmission link requires an intermediate energy storage device, which increases the construction cost and device complexity, and affects the power generation quality and reliability of the power generation device

Abstract

The invention discloses a vertical-axis wave-activated generator. The vertical-axis wave-activated generator comprises vanes, a rotating shaft, a strut, an above-water platform exposed out of the sea level, a generator body, a vane height increasing device, a control device and a base, wherein the generator body, the vane height increasing device and the control device are arranged on the above-water platform. The vanes are fixed to the rotating shaft in the circumferential direction, the upper end of the strut is embedded in and sleeved with the rotating shaft through a bearing, the lower end of the strut is fixedly connected with the base, the above-water platform is fixed to the upper end of the strut, the generator body and the output end of the rotating shaft are in drive connection, the vane height increasing device is arranged at the upper end of the rotating shaft and used for adjusting the draught of the vanes, and the control device is connected with a generator circuit and used for controlling continuous and stable output of electric energy. The arrangement of the vertical-axis wave-activated generator on the sea is independent of the direction of incident waves, the vanes drive the rotating shaft to rotate so as to directly drive the generator body to generate electricity, the complexity of middle link energy transfer, energy storage and voltage stabilization of an ordinary wave-activated generator is omitted, the conversion efficiency and the electricity generating quality of wave energy are improved, and the vertical-axis wave-activated generator is convenient to maintain and low in manufacturing cost.

Description

technical field [0001] The invention relates to an ocean wave energy generating device, in particular to a vertical axis wave generator for directly generating electricity by using wave energy. Background technique [0002] With the progress of society and economic development, the human demand for energy is increasing, but the development of conventional energy can no longer meet this demand. At the same time, environmental pollution and ecological damage force people to look for new forms of alternative energy. As a renewable energy with large reserves that has not been fully developed and utilized on the earth, the development and utilization of ocean energy is becoming a hot spot in the international community. Among them, wave energy has the characteristics of large reserves and little impact on the development of regional environment, and has become the focus of ocean energy development and utilization. The development and application of wave power generation will be ...
