Problems solved by technology

The difference is that sea water is different from river water. The accumulated sea water has a small drop, but the flow is large and intermittent. Therefore, the structures of tidal power turbines currently used must be suitable for the characteristics of low water head and large flow.

Embodiment 1

[0011] Such as figure 1 As shown, a tidal power generation device is provided with a buoyancy chamber 2 filled with air in the lower part of the water storage chamber 1, and an oil cylinder 3 is arranged in the lower part of the buoyancy chamber 2, and the oil cylinder 3 is fixedly connected with the base 4; the bottom of the oil cylinder 3 is provided with an oil outlet pipe 5 and The oil inlet pipe 6 and the oil outlet pipe 5 are connected to the turbine generator set 9 through the oil outlet check valve 7 , and the oil inlet pipe 6 is connected to the oil storage tank 10 through the oil inlet check valve 8 .

Embodiment 2

[0013] refer to figure 1 , the tidal power generation device of the present embodiment, which is the same as embodiment 1 and figure 1 The difference of the shown tidal power generation device is that three oil cylinders 3 are evenly distributed in the lower part of the buoyancy chamber 2, and the oil inlet pipes of each oil cylinder 3 are connected, and the oil outlet pipes are connected.

[0014] The tidal power generation device in the above embodiments can be installed in semi-floating or floating offshore. As long as the tidal range is above 3m, it can adapt to various geographical conditions in the offshore. When the tidal power generation device is working, the seawater is stored in the water storage tank. When the tide rises, the buoyancy tank pushes the water storage tank up to make it higher than or equal to the sea level, and it is stored in the form of potential energy. At the same time, the oil inlet check valve is turned on, and the hydraulic oil enters the oil ...

Abstract

The invention discloses a tidal power generation device comprising a water storage chamber and a marine engine generating unit. The tidal power generation device is characterized in that a buoyancy chamber full of air is arranged at the lower part of the water storage chamber; an oil cylinder is arranged at the lower part of the buoyancy chamber; the oil cylinder is fixedly connected with a base; an oil outlet pipe and an oil inlet pipe are arranged at the bottom of the oil cylinder; the oil outlet pipe is communicated with a turbine generating unit through an oil outlet one-way valve; and the oil inlet pipe is communicated with an oil storage tank through an oil inlet one-way valve. With the adoption of the tidal power generation device, the problems that the traditional device is poor in self-starting property, low in efficiency and the like can be solved; the tidal power generation device has a good comprehensive property, and is particularly applicable to being used as a long-acting power supply electrode of a beacon light, marine hydrology remote-sensing equipment and maritime meteorology remote-sensing equipment with less electricity. Particularly, the tidal power generation device supplies power to coasts and island areas with inconvenience in traffic, difficulty in power supply or no normal power supply, and further supplies the power to coastal villages, garrisons, farms and the like.

Description

technical field [0001] The invention relates to a tidal power generation device, in particular to a device for generating power by using ocean wave energy and tidal energy, and belongs to the technical field of clean energy. Background technique [0002] There is a huge amount of energy in the tides of the ocean. Generally speaking, an average tidal range above 3m has practical application value, and the main method of utilization is power generation. Despite the complexity of tides, accurate tide forecasts can be made anywhere. Tidal power generation uses favorable terrain such as bays and estuaries to build embankments and form reservoirs to store a large amount of seawater, and build hydropower plants in or beside the dam to generate electricity through hydroelectric generator sets. Harvesting energy from tides is only possible when there are high tides, energy is concentrated, and where the geographical conditions are suitable for building tidal power plants. Although...
