Problems solved by technology

[0003] In 1967, the first large-scale tidal power station - Lens Tidal Power Station was put into commercial operation in France, and it is still in normal operation today, proving that tidal power generation is technically feasible and economically promising, but since the 1980s, there has been almost no The main constraints of newly-built tidal power stations are the high construction cost and the impact on marine functions and the environment: tidal power stations are usually built in bays, have a large reclamation area, and are prone to conflicts with other projects
[0004] Secondly, the form of the reservoir cannot generate electricity when the seawater height does not fluctuate or fluctuates slightly, which restricts the amount of power generation and the improvement of economic benefits, which in turn restricts the application of tidal power generation.

Embodiment 1

[0025] see Figure 1-2 An offshore tidal power generation device includes a generator set 1, the generator set 1 is a bidirectional turbine generator capable of generating electricity both in and out of the water, and also includes a lifting member 2, a traction rope 3, a positioning member 4 and a cable 5;

[0026] The lifting part 2 rotates around the positioning part 4 under the action of the traction rope 3. The traction rope 3 is connected to the lowest point vertical to the lifting part 2 to ensure that the lifting part 2 is horizontal. The lifting part 2 rotates around the traction rope 3 so that it faces It is always consistent with the direction of the water flow, reducing the overall resistance and reducing the load of the lifting part 2. The traction rope 3 and the positioning part 4 form an angle a, and the angle a changes with the resultant force of the lifting part 2, thereby changing the height of the lifting part 2. The height and resultant force are mainly for...

Embodiment 2

[0033] refer to image 3 , the difference from Embodiment 1 is that the positioning member 4 is fixedly connected to the bottom of the offshore platform, and is connected with the traction rope 3 and the cable 5 through a slip ring. Powered by the platform.

[0034] Principle of work and work flow of the present invention:

[0035] tidal power

[0036] At high tide, the sea level rises. The pressure at the inlet and outlet of empennage 7 increases, seawater is pressed into the space of compressed gas chamber 6 in empennage 7, and the pressure of compressed gas chamber 6 is increased, so that the resultant force of elevating member 2 changes: in embodiment one, elevating member The overall density of 2 increases, the buoyancy decreases, and the upward force decreases; in embodiment two, the buoyancy decreases, and the downward force increases; the lifting member 2 moves downward until the pressure in the compressed gas chamber 6 is the same as that of seawater , when the ti...

Abstract

The invention relates to the technical field of ocean engineering, and discloses an offshore tidal power generation device. The device comprises a generator set, a lifting part, a traction rope, a positioning part and a cable, and the lifting part rotates around the positioning part under the action of the traction rope. The offshore tidal power generation device is constructed far away from the coast, is not limited by geographic space, is flexible to construct, and is more convenient to promote and popularize; secondly, a single body is small in size and convenient to maintain, does not change the landform, has small influence on the environment and ocean functions, can generate power by using potential energy formed by tides and kinetic energy of ocean current, and can generate power around the clock, improve the power generation amount and reduce the power generation cost after being constructed; and finally, application and installation are flexible, on one hand, the position canbe flexibly adjusted along with seasonal changes of ocean currents and tides, more points are emitted at the best position, and on the other hand, the device can be flexibly used for various offshorefixed platforms or movable platforms, and application scenes are increased.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to an offshore tidal power generation device. Background technique [0002] The tide is a phenomenon of water level change caused by the gravitational force of the moon or the rotation of the earth. When the tide is high, a large amount of seawater surges in and converts kinetic energy into potential energy. When the tide is low, the potential energy is converted into kinetic energy and rushes back. figure 1 , When the tide is high, the tide flows into the reservoir and becomes potential energy storage, and at the same time drives the motor to rotate to generate electricity; [0003] In 1967, the first large-scale tidal power station - Lens Tidal Power Station was put into commercial operation in France, and it is still in normal operation today, proving that tidal power generation is technically feasible and economically promising, but since the 1980s, there has been alm...
