Description

A mobile wave generator

Technical field

The present invention relates to the technical field of power generation, and in particular to a wave generator.

Background technique

The clean energy that nature can provide: solar power generation is limited by weather, sunshine time and region; wind power generation is limited by weather and region; hydropower generation is limited by weather, reservoir capacity, large investment and huge projects. The tidal phenomenon refers to the periodic movement of sea water under the action of the tidal force of celestial bodies. It is customary to refer to the vertical rise and fall of the sea surface as tides, which are also commonly known as waves. Tides are a natural phenomenon in coastal areas. Tidal energy is like Like solar energy, it contains huge energy, which is both energy-saving and environmentally friendly, and is inexhaustible. At present, humans have used tides to generate electricity. Ocean tidal power generation is also a clean energy source provided by nature. Ocean tidal power generation is not restricted by time and weather and can generate electricity throughout the day with low investment and low maintenance costs. The existing tidal power generation technology is to build dams, gates and workshops in qualified bays or tidal inlets to form a reservoir. A certain tidal difference is formed between the water level of the reservoir and the tide level of the outer sea, which can drive the hydroelectric generator set to generate electricity. The principle of tidal power generation is similar to that of ordinary hydropower generation. By leaving the reservoir, seawater is stored in the reservoir during high tide and stored in the form of potential energy. Then, seawater is released at low tide, using the difference between high and low tide levels to drive the rotation of the turbine. , drives the generator to generate electricity. However, most of the current tidal generator power generation platforms are fixed and cannot be moved. At the same time, the tidal generator is immersed in water. The entire device is located under the sea level, and is subject to the corrosion of seawater, which affects the life of the equipment, and must be maintained underwater. , replacement and installation operations, installation and maintenance are difficult, and its scope of application is limited.

A Chinese invention patent with application number CN200910089573.5 and application publication number CN101614180A discloses a composite device that uses ocean wave energy to generate electricity, which includes a floating body, an energy harvesting device 1, an energy harvesting device 2, a power generation device and a fixed platform. The energy harvesting device is composed of an impeller, a bracket, a speed-increasing transmission device, a support platform, etc. The second energy harvesting device consists of a cylinder, a piston, a connecting rod, an intake and exhaust check valve, a gas storage tank, a steam turbine, etc. The first feature is that a floating body is arranged on the wave-facing surface of the sea, and an impeller with blades is provided on the floating body. The wave motion drives the blades to rotate and drives the intermediate shaft of the impeller to rotate together. The intermediate shaft drives the generator through the speed-increasing transmission device to generate electricity. The second feature is that the floating body is connected to the piston in the cylinder through a connecting rod. When floating, the exhaust one-way valve on the cylinder that is connected to the gas storage tank is closed, and the intake one-way valve that is connected to the atmosphere is opened, and gas is injected into the cylinder. When falling, the air inlet one-way valve connected to the atmosphere on the cylinder is closed, the exhaust one-way valve connected to the gas storage tank is opened, and the gas in the cylinder is compressed and enters the gas storage tank. When the gas in the gas storage tank reaches a certain pressure, the pressure valve automatically opens to promote the rotation of the steam turbine, which in turn drives the generator to generate electrical energy. The power generation equipment provided by the invention uses two energy harvesting methods to generate power at the same time, and can double-efficiently utilize the inexhaustible ocean wave energy for power generation, with good economic benefits. However, since the fixed platform is fixed at a certain position on the sea level by setting anchor chains on the seabed, the above-mentioned problems still exist.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, but should not be construed as limiting the invention.

Example 1.

Figure 1 shows the core structure of an embodiment of the mobile wave generator of the present invention. The core structure of the mobile wave generator consists of a floating body 1, a connecting rod 2, a pressurized water tank (gravity tank) 3, a lifting ring 4, a magnet 5 and a power generation coil 6. The magnet 5 moves up and down in the power generation coil 6. The pressurized water tank 3 and the power generation coil 6 are fixedly connected together and arranged on the support member. The magnet 5 and the floating body 1 are connected to the floating body 1 through the connecting rod 2, and the connecting rod 2 passes through the pressure The central hole of the water tank 3 and the pressure water tank 3 are also provided with a lifting ring 4.

Its working principle: huge waves come, sea level A rises sharply, floating body 1 rises sharply with sea level A, floating body 1 drives magnet 5 into power generation coil 6 through connecting rod 2, and the magnetic flux in power generation coil 6 changes to generate electromotive force. The magnetic reaction force against the change of magnetic flux in the power generation coil 6 is offset by the weight of the pressure water chamber 3 (gravity chamber, a heavy object filled with seawater), and the position remains unchanged.

Example 2.

As shown in Figure 2, the mobile wave generator of the present invention adds load-bearing pillars 7 as supporting members and is erected on the shallow sea. The pressurized water tank 3 is set on the load-bearing pillars 7. Its appearance is like a water tower standing in the sea. The gravity of the pressurized water tank 3 On the load-bearing pillar 7, make the pillar stand on the seabed B and not be knocked down by the waves.

Example three.

As shown in Figure 3, the mobile wave generator of the present invention can also be erected in the deep sea. In the second embodiment, in order to prevent the power generation coil 6 from being submerged when the tide rises, a protective floating body can be added to the load-bearing pillar 7 or under the pressurized water tank 3. 8. This can prevent the power generation coil 6 from being submerged during high tide.

Example 4.

Figure 4 shows an embodiment applied to deep sea. As a deformation structure of the third embodiment, the protective floating body 8 in the third embodiment is transformed into a suspended platform 9 as a supporting member. The suspended platform 9 is arranged below the pressurized water tank 3. The whole set of equipment, including the pressurized water tank 3 and the power generation coil 6, relies on the floating platform 9 to float above the sea level A. In this case, the load-bearing pillar 7 is not needed.

As shown in Figure 5, the suspended platform 9 is also used, except that the suspended platform 9 is fixed under the pressurized water tank 3 through supporting columns. Under the action of the common buoyancy of the protective floating body 8 and the suspended platform 9, the suspended platform 9 is located at sea level A at this time. Below, in the semi-submersible state in the deep sea, the suspended platform 9 is less affected by waves compared to Figure 4 .

Example 5.

As shown in Figure 6, the mobile wave generator of the present invention can be applied to a ship 10. Its supporting component is a lifting ring 4 connected to a sling 12 provided on the pressurized water tank 3. The ship 10 is provided with a boom 11 and a sling 12. Connected to the boom 11, the floating body is placed at sea level A, the pressure water tank 3 gravity is downward, and the floating body floats upward with the waves.

The working principle of the mobile wave generator of the present invention that can be used in deep sea and ships 10 is as follows.

In the sea, when huge waves come, a giant ship and a small wooden boat are lifted up by the waves. However, because the weight of the giant ship is much greater than that of the small wooden boat, the floating displacement and speed of the giant ship are much smaller than that of the small wooden boat. Displacement and speed, there is a floating displacement difference and floating speed difference between the giant ship and the small wooden boat. The suspended platform 9, pressurized water tank 3 (gravity tank, a heavy object filled with seawater) and power generation coil 6 are equivalent to a giant wheel. The floating body, connectors and magnets 5 are equivalent to a small wooden boat. When a huge wave comes, the power generation coil 6 floats and moves and the floating speed is less than the floating displacement and floating speed of the magnet 5, the magnet 5 enters the power generation coil 6, and the magnetic flux in the power generation coil 6 changes to generate an electromotive force. The magnetic reaction force against the change of magnetic flux in the power generation coil 6 is offset by the weight of the pressure water chamber 3 (gravity chamber, a heavy object filled with seawater). The ship 10 and the suspended platform 9 float on the surface of the deep sea, achieving the goal of generating large wave power in deep sea without building a solid foundation.

The pressurized water tank 3 of the present invention plays a key role.

1) The huge weight of the pressurized water tank in the shallow sea presses heavily on the load-bearing pillars, allowing the load-bearing pillars to "stand" on the seabed B without a fixed foundation. This also plays a key role in enabling the equipment to move without a fixed foundation.

2) The huge weight of the pressurized water tank offsets the magnetic reaction force of the power generation coil 6.

3) In the deep sea, the huge weight of the pressurized water tank is far greater than the weight of the floating body and the combined magnetic force of the moving magnet 5 on the power generation coil 6. When a huge wave comes, the pressurized water tank and the floating body float up at the same time. However, due to the existence of the pressurized water tank and the floating body, There is a huge weight difference, and there is a difference in floating displacement and floating speed when the two float. The corresponding power generation coil 6 and the magnet 5 have relative displacements. The magnet 5 moves in and out of the power generation coil 6 to generate electricity.

The marine tidal power generation method of the present invention is not restricted by time and weather, can generate electricity throughout the day, and has low investment and maintenance costs. Mobile wave generators can also be used in the river to generate secondary power when the water level in the river rises rapidly when the dam releases water. Has the following characteristics.

1. Use the weight of the mobile wave generator to place the load-bearing pillar on the seabed B or the suspended platform. The seabed B or the suspended platform bears the weight of the mobile wave generator.

2. The electromagnetic reaction force of the magnetic force of the power generation coil cutting the magnetic column is offset by the own weight of the pressurized water tank.

3. Store heavy objects in the pressurized water tank. The heavy objects can be sea water, cement, iron blocks, etc.

4. The magnet 5 moves up and down in the power generation coil to cut the magnetic lines of force.

5. The entire power generation equipment completely floats above the sea.

6. There are waves at sea level A causing sea surface fluctuations.

The mobile wave generator of the present invention has the advantages of simple structure, easy processing, low investment, no construction, no maintenance, high economic benefits, environmental protection and all-day power generation. However, the power generation voltage and current are unstable and uncontrolled and can easily burn out. The disadvantage of the rectifier equipment is that it is not as stable and controllable as the tidal energy storage generator in terms of the stability and controllability of the generated voltage and current. Since the entire power generation equipment completely floats above the sea, maintenance, replacement, and installation are convenient and safe, preventing seawater from directly corroding the power generation equipment, and also avoiding maintenance, replacement, and installation operations underwater. Concrete can also be used as materials for the load-bearing pillars, power generation coil seats and floating bodies of mobile tidal generators to greatly reduce costs, reducing costs for giant stand-alone tidal generators. Using a suspended platform structure in the deep sea (Figure 3), huge single-machine tidal generators and array tidal generators with large power generation capacity can be produced with a drop of up to 100 meters in the deep sea.

There are tens of thousands of kilometers of coastline around the world, and the power generated by the array of mobile wave generators is astronomical. There are waves on the sea surface all the time, and the mobile wave generator also generates electricity all the time. Mobile wave generators provide power and energy security for island countries lacking energy. There is almost no coal and natural gas production capacity in my country's coastal areas, and they all rely on transportation from outside areas, which seriously restricts the development of coastal areas. The utilization of ocean tidal energy can reduce dependence on thermal power generation, especially for ocean island countries that lack energy. Mobile wave generators bring abundant electricity to coastal areas, which can promote the establishment of energy-consuming enterprises (energy-consuming enterprises such as oil refining, steelmaking, casting, industrial heating and steam supply), drive economic development and employment in coastal areas, and provide People in coastal areas bring economic benefits from the sale of electrical energy. The application of mobile wave generators in the East China Sea and South China Sea has changed the energy pattern of my country's west-to-east power transmission.

Our country is a strong country in infrastructure construction. We already have the technology to build cross-sea bridges and the technology to manufacture giant generators like the Three Gorges Dam. We are fully capable of building giant suspended platforms in the ocean and manufacturing and installing giant mobile wave generators. We also have the technology to build giant generators like the Three Gorges Dam. The capability is used as technological output to help other countries build giant suspended platform tidal generators.

The application of mobile wave generators has important civilian and military significance. It provides power and hydrogen energy supply and support for islands and ocean navigation, and provides power support for electrolytic hydrogen production, oxygen production, and seawater desalination. The application of mobile wave generators provides power and energy guarantee for the construction of ocean and submarine cities.
