Combined type ocean power generation device

Abstract

The invention provides a combined type ocean power generation device. The combined type ocean power generation device comprises a base and a main body, wherein the main body is fixedly connected with the base; an upper cavity is arranged in the upper end of the main body; a lower cavity is arranged in the lower end of the main body; a sealing plate is arranged at the upper end of the upper cavity and rotationally connected with a rotary shaft; the rotary shaft is horizontally arranged, one end of the rotary shaft is fixedly connected with vanes, and the rotary shaft is connected with an input shaft of a generator through a speed reducer; a generator II is arranged in the upper cavity, a transmission structure capable of driving an input shaft of the generator II to rotate when the rotary shaft rotates is arranged between the input shaft of the generator II and the rotary shaft; a through hole is horizontally formed in the lateral wall of the lower end of the lower cavity, and a generator III is arranged in the through hole; a swinging generator is arranged at the outer end of the through hole; a ventilation hole is formed in the lateral wall of the main body and fixedly connected with a valve capable of controlling the ventilation hole to open and close; a plurality of base protecting devices are further arranged on the base. According to the combined type ocean power generation device, scouring of ocean currents to the base can be reduced, and wind energy and tidal energy are fully used for power generation.

Description

technical field [0001] The invention belongs to the technical field of ocean energy utilization equipment, and relates to a composite ocean power generation device. Background technique [0002] With the crisis of energy and environment, people are becoming more and more aware of the importance of clean energy. The ocean contains huge free energy, such as wind energy, wave energy, tidal energy, etc. At present, a large number of marine wind energy is used to drive power generation through wind blades. However, the weather on the sea changes greatly. When encountering severe weather such as strong winds, it is easy to cause the blades to rotate too fast, which is easy to affect the life of the generator. In addition, the very large energy contained in strong winds, How to make full use of the wind energy in windy weather is an urgent problem to be solved. [0003] In addition, when encountering severe weather such as strong winds, since the composite marine power generation ...

[0002] With the crisis of energy and environment, people are becoming more and more aware of the importance of clean energy. The ocean contains huge free energy, such as wind energy, wave energy, tidal energy, etc. At present, a large number of marine wind energy is used to drive power generation through wind blades. However, the weather on the sea changes greatly. When encountering severe weather such as strong winds, it is easy to cause the blades to rotate too fast, which is easy to affect the life of the generator. In addition, the very large energy contained in strong winds, How to make full use of wind energy in windy weather is an urgent problem to be solved

[0003] In addition, when encountering severe weather such as strong winds, since the composite marine power generation device is directly in the ocean, harsh environments such as strong winds and waves will directly affect the composite marine power generation device, which may easily lead to damage to the composite marine power generation device , resulting in economic loss

[0004] Due to the influence of ocean currents, the hydrodynamic characteristics near the base of the ocean power generation device are complex, and the ocean currents will have a scouring effect on the base. As time goes by, the stability of the base will decrease due to the long-term impact of scouring. Then destroy the structure of the base, so that the entire marine power generation device has potential safety hazards
