Description

Movable tidal power generator

Technical Field

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

Background

The nature can provide clean energy: solar power generation is limited by weather, sunshine time and regions; wind power generation is limited by weather and regions; hydroelectric power generation is limited by weather, reservoir capacity, large investment and huge engineering. The tidal phenomenon refers to the periodic motion of seawater under the action of celestial body tidal force, the fluctuation in the vertical direction of the sea surface is customarily called as tide, namely wave, the tide is a natural phenomenon in coastal areas, and the tidal energy is like solar energy, contains huge energy, is energy-saving and environment-friendly, and is inexhaustible. At present, human beings generate electricity by utilizing tides, ocean tidal power generation also belongs to clean energy provided by nature, is not limited by time and weather, can generate electricity all day long, and has low investment and maintenance cost. The existing tidal power generation technology is that a dam, a gate and a factory building are built in a conditional bay or a tidal interface to form a reservoir, and a certain tidal difference is formed between the water level of the reservoir and the sea tide level, so that a water-turbine generator set can be driven to generate power. The tidal power generation is similar to the principle of common hydroelectric power generation, seawater is stored in a reservoir in the tide rise mode through the reservoir and is stored in the potential energy mode, then the seawater is discharged in the tide fall mode, and the water turbine is pushed to rotate by utilizing the difference between high and low tide levels to drive a generator to generate power. However, most of the existing tidal power generator power generation platforms are fixed and cannot move, the tidal power generators are immersed in water, the whole device is positioned under the sea level and is affected by the corrosion action of seawater, the service life of the device is influenced, the tidal power generator power generation platforms need to be maintained, replaced and installed underwater, the installation and maintenance difficulty is high, and the application range of the tidal power generator power generation platforms is limited to a certain extent.

A Chinese patent with application number of CN200910089573.5 and application publication number of CN101614180A discloses a combined type device for generating power by using ocean wave energy, which comprises a floating body, a first energy obtaining device, a second energy obtaining device, a power generating device and a fixed platform. The first energy obtaining device comprises an impeller, a bracket, a speed increasing transmission device, a supporting platform and the like. The energy obtaining device II comprises a cylinder, a piston, a connecting rod, an air inlet and exhaust one-way valve, an air storage tank, a steam turbine and the like. The marine impeller is characterized in that a floating body is arranged on a wave-facing surface on the sea, and an impeller with blades is arranged on the floating body. The wave motion pushes the blades to rotate and drives the intermediate shaft of the impeller to rotate together, and the intermediate shaft drives the generator to generate electricity through the speed-increasing transmission device. The floating body is connected with a piston in a cylinder through a connecting rod, an exhaust one-way valve communicated with a gas storage tank on the cylinder is closed when floating upward, an intake one-way valve communicated with the atmosphere is opened, and gas is injected into the cylinder. When the air falls, the air inlet one-way valve communicated with the atmosphere on the air cylinder is closed, the air exhaust one-way valve communicated with the air storage tank is opened, and the air in the air cylinder is compressed to enter the air storage tank. When the gas in the gas storage tank reaches a certain pressure, the pressure valve is automatically opened to push the steam turbine to rotate, and then the generator is driven to generate electric energy. The power generation equipment provided by the invention can generate power by adopting two energy obtaining modes at the same time, can efficiently utilize inexhaustible ocean wave energy in a double way to generate power, and has good economic benefit. However, the above problems still exist because the fixed platform is fixed at a certain position on the sea level by arranging anchor chains on the sea bottom.

The first embodiment.

As shown in fig. 1, the mobile tidal generator) is composed of a generating coil seat floating body 10, a generating coil seat 4, a generating coil 7, a magnetic column 8, an equipment protecting floating body 1, a magnet seat 5, a bearing support column 3 and a pressurized-water cabin 6, wherein the magnet seat 5 is downwards connected with the equipment protecting floating body 1 through a protecting floating body connecting piece 2, and the number of the equipment protecting floating bodies 1 is two or more, and the two or more equipment protecting floating bodies 1 are symmetrically or circumferentially and uniformly distributed; the magnetic columns 8 are arranged on the magnet seat 5, the magnetic columns 8 are arranged in the middle of the magnet seat 5 in the embodiment, the magnetic columns 8 form S poles and N poles which are alternately distributed at intervals along the axial direction of the columns, the water pressing bin 6 is arranged above the power generation coil seat 4, the magnetic columns 8 and the magnet seat 5, the water pressing bin 6 is used for counteracting the magnetic force counterforce of the magnetic force of the magnet on the power generation coil due to the dead weight of the whole equipment, the bearing support column 3 is placed on the sea bottom and protrudes out of the sea level, and the magnet seat 5 is fixed at the upper end of the bearing support column 3 so as to keep that the magnet seat 5 can ascend under the floating force action of the equipment protection floating body 1; the power generation coil 7 is arranged on the power generation coil base 4, a through hole for accommodating the magnetic column 8 to pass through is formed in the power generation coil base 4, and the magnetic column 8 passes through the through hole, the power generation coil 7 and the power generation coil base 4 form a sleeving structure capable of moving relatively. The power generation coil base floating bodies 10 are arranged at the bottom of the power generation coil base 4 through power generation floating body connecting pieces 9 and used for supporting the power generation coil base 4, and the number of the power generation coil base floating bodies 10 is two or more and the two or more power generation coil base floating bodies are symmetrically or circumferentially and uniformly distributed. The generating coil 7 is arranged on the generating coil holder 4. The generating coil 7 is sleeved on the periphery of the magnetic column 8. The movable tidal generator is placed on the seabed B, namely a bearing support column 3 contacts the surface of the seabed B, the buoyancy of a floating body 10 of the generating coil seat supports the generating coil seat 4, when sea waves rise, the sea level A rises rapidly, the floating body 10 of the generating coil seat supports the generating coil seat 4 to rise along with the rise of the sea surface, the generating coil 7 moves upwards on the magnetic column 8 to generate electricity (Faraday electromagnetic induction law), and the electromagnetic reaction force of the generating coil 7 cutting the magnetic lines of force of the magnetic column 8 is counteracted by the self weight of the pressurized water tank 6; when the sea wave is withdrawn, the floating body 10 of the power generation coil base supports the power generation coil base 4 to automatically fall back to the sea level A under the condition of self weight, the power generation coil 7 moves downwards on the magnetic column 8 to cut magnetic lines of force to generate power, and the power generation process of the sea wave crest is completed. The wave crest of the sea surface all day is continuous, and the power generation coil 7 can move up and down on the magnetic column 8 to cut the magnetic force line to generate power all day long as the sea surface fall caused by sea waves is generated.

When the sea wave or tide water level is higher than the equipment protection floating body 1, the equipment protection floating body 1 supports the whole mobile tide generator to float on the sea surface, so that the bearing support 3 is separated from the sea bottom, and the whole mobile tide generator is prevented from being submerged by the sea water. The apparatus of the present invention protects the floating body 1 from flooding the mobile tidal generator with waves or flood tides. There is no infrastructure to secure the mobile tidal generator.

The device protection floating body 1 of the embodiment adopts a buoyancy block, the floating body 10 of the power generation coil base adopts a floating ball to support the power generation coil base 4 so that the power generation coil base 4 fluctuates up and down along with the sea level, and of course, a person skilled in the art can adopt other floating bodies with a supporting and floating function according to actual needs, such as a floating barrel, a floating ring and the like. Because the power generation equipment of the tidal power generator completely floats above the sea surface, the tidal power generator is convenient and safe to maintain, replace and install, avoids seawater from directly corroding the power generation equipment, also avoids maintenance, replacement and installation operation under water, and has the advantages of simple structure, easiness in processing, low investment, low construction difficulty, low maintenance cost, high economic benefit, environmental protection, full-day power generation and the like.

Example two.

Compared with the embodiment, the tidal generator can be converted into the structure shown in figure 2, wherein the magnet base 5 is omitted, the magnetic column floating body 11 is directly arranged at the bottom of the magnetic column 8, the water pressing bin 6 is directly arranged at the upper part of the generating coil base 4, the bearing support 3 is fixed on the generating coil base 4, and the equipment protecting floating body 1 is fixed on the generating coil base 4 through the protecting floating body connecting piece and is positioned at the periphery of the bearing support 3. The floating device that keeps the relative movement between the generating coil 7 and the magnetic column 8 at this time becomes the magnetic column floating body 11 instead of the generating coil holder floating body 10 in the first embodiment.

Example three.

As shown in fig. 3, the main difference between the mobile tidal generator of the present invention and the second embodiment is that the load bearing columns 3 do not contact the seabed B, but are fixed to a floating platform 12, the floating platform 12 being located between the seabed B and the sea level a.

The ocean tidal power generation is not limited by time and weather, can generate power all day long, and has less investment and maintenance cost. The fall of the river course water level rising rapidly when the dam discharges the flood can also use the movable tidal generator in the river course to carry out secondary power generation. Has the following characteristics.

1. The load-bearing support column 3 is pressed on the seabed or on the suspension platform by the self weight of the mobile tidal generator, and the seabed or the suspension platform bears the self weight of the mobile tidal generator.

2. The electromagnetic reaction force of the magnetic force of the generating coil 7 for cutting the magnetic column 8 is offset by the self weight of the pressurized water bin 6.

3. The water pressing bin 6 stores heavy objects, and the heavy objects can be seawater, cement, iron blocks and the like.

4. The generating coil 7 is sleeved on the magnetic column 8 to move up and down for cutting magnetic lines.

5. The whole power generation equipment completely floats above the sea surface.

6. Sea level has sea wave to cause sea level fluctuation fall.

The mobile tidal power generator has the advantages of simple structure, easy processing, less investment, no construction, no maintenance, large economic benefit, environmental protection, full-day power generation and the like, but also has the defect that the generating voltage and the generating current are not stable and are easy to burn out rectifying equipment, and the stability controllability of the generating voltage and the generating current is not superior to that of a tidal energy storage generator. Because the whole power generation equipment completely floats above the sea surface, the maintenance, the replacement and the installation are convenient and safe, the seawater is prevented from directly corroding the power generation equipment, and the maintenance, the replacement and the installation operation under water are also avoided. The materials of the bearing support column, the generating coil seat and the floating body of the movable tidal generator can also use concrete to greatly reduce the cost, thereby reducing the cost of the giant single-machine tidal generator. In deep sea, a suspended platform type structure (figure 3) is adopted, and the fall of the deep sea up to 100 meters can manufacture huge single-machine tidal generators and array tidal generators with large power generation quantity.

The coastline is tens of thousands of kilometers around the world, and the electricity generated by the arrayed mobile tidal generators is an astronomical number. The sea surface turns up the wave at all times, and the movable tidal generator also generates electric energy at all times. The mobile tidal generator provides power energy guarantee for the island countries with energy shortage. The coastal areas of China hardly have coal and natural gas capacity, and all the coastal areas depend on the allocation and transportation of foreign areas, so that the development of the coastal areas is severely restricted. The use of ocean tidal energy can reduce the dependence on thermal power generation, especially in ocean island countries where there is a lack of energy. The movable tidal power generator brings abundant electric power for coastal areas, can promote energy-consuming enterprises (oil refining, steel making, casting, industrial heat supply and steam supply and other energy-consuming enterprises) to advance, drive economic development and employment of the coastal areas, and bring economic benefits for selling electric power energy for people in the coastal areas. The application of the mobile tidal power generator in the east sea and the south sea changes the energy pattern of the west-east power supply in China.

China is a strong foundation construction country, has a technology for building a cross-sea bridge and a technology for manufacturing a giant generator of a three gorges dam, is completely capable of building a giant suspension platform and manufacturing and installing a giant movable tidal generator at the ocean, and is more capable of being used as a technical output to help other countries to build the giant suspension platform type tidal generator.

The application of the mobile tidal generator has important military significance, provides power guarantee for islands, oceans and seabed armies, provides power guarantee for hydrogen and oxygen production by electrolysis and seawater desalination, and provides electric energy for power consumption defensive weapons (laser weapons and electromagnetic weapons). The application of the movable tidal generator provides electric power energy guarantee for constructing oceans and submarine cities.

It will be appreciated by those skilled in the art from the foregoing description of construction and principles that the invention is not limited to the specific embodiments described above, and that modifications and substitutions based on the teachings of the art may be made without departing from the scope of the invention as defined by the appended claims and their equivalents.
