After the formal delivery, the adjustment and the control of the energy accumulator are carried out, and an accurate plan can be made in advance according to the hours of electricity supplied every day.
Second, the development potential of ocean current power generation

On a general wide sea surface, the flow velocity is about one section in a tidal torrent period. The water turbine can rotate to generate power at more than zero point and three water turbines, but the investment recovery period is shortened, generally, the water turbine is suitable for a water-saving and water-saving flow rate channel installation, and in places with rapid flowing water for a long time (such as the channel in the Johnson state), the flow rate is one to five in different time periods, and the recovery period is estimated by years of experimental experience, for example, the water turbine is installed to generate power at three and forty meters deep water positions, and is about three years. The water depth of some straits is more than 50 m, the flow speed is three to five sections for a long time, and the installed power generation recovery period can be shortened to one or two years. In large straits between continents, straits between islands and land, and black-flow zone waters of oceans, flowing water is particularly rapid, generally, the flow rate is two to five sections, and the two-head land of some straits forms a bell mouth shape, and the flow rate can reach six to eight sections when the flow rate is fastest. The running water is more urgent under the influence of weather (typhoon). Therefore, ocean current power generation has great development potential.
Due to the fact that flowing water flows forward and backward every night every day and the instability of high and low flow speed, how to build the ocean current power generation platform is important to collect and utilize ocean current energy.

Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the drawings and examples, so that how to apply the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented. It should be noted that, as long as there is no conflict, the embodiments and the features of the embodiments of the present invention may be combined with each other, and the technical solutions formed are within the scope of the present invention.
Particularly, the ocean current power generation platform can be built in a sea area with more than two throttling speeds without influencing a navigation channel and submarine cables and submarine military facilities, and the general platform construction has obvious benefits only in the sea area with thirty meters of water depth to one hundred meters of water depth, so that the networking can be produced in a large scale. If the power generation platform is built at a thirty-meter deep water position, the diameter of the blades of the water turbine can only be twenty meters, if the power generation platform is built at a fifty-meter deep water position, the diameter of the blades of the water turbine can only be forty meters, for preventing the influence of typhoon and big waves, the blades of the water turbine are reserved for the platforms built at different water depths, and the blades of the water turbine can not be installed on a flat water surface. According to experimental experience of many years, the thirty-meter deep water and twenty-meter diameter water turbine generates about two megawatt hours at five flow rates and generates about four hundred kilowatt hours in average annual energy generation. If the power generation platform is arranged at a water depth position of fifty meters, the diameter of a blade of the water turbine is forty meters, and the flow speed is five hours, the power generation amount is about nine megawatt hours, and the annual average power generation amount is about two megawatt hours. The power generation platform consists of two main square piles and four circular inclined piles, and the square piles are provided with sliding grooves for the vertical hoisting, maintenance, disassembly and assembly of the water turbine. For example, the number of the inclined piles in the sea area with very fast running water can be increased to six and eight or more. Besides the six main devices, a hoisting platform and a working platform for hoisting the hydraulic turbine are also arranged on the main devices, and a stair for workers to go up and down the platform to work is also arranged on the main devices. In addition, a plurality of triangular force applying frames are built from the ground to the water surface, so that the water turbine concentrates the force of six piles. The number of the inclined piles of the power generation platform is determined according to different water depths and different flow rates. The construction of ocean current power generation platforms needs to be fixed by piling at different water depths and different flow velocities on seabed, for example, in the sea area of a New Port island in Haikou City in Hainan province, ocean current power generation test projects, a small platform for debugging thirty-five meter deep water positions, two square piles are eighty-eight meters long each, four diagonal piles are eighty-ten meters each, piling is needed to be carried out to the underground part, the six piles and a small hoisting platform for a water turbine hung on the water surface form an ocean current power generation platform, and the total weight of the ocean current power generation platform is about seven hundred tons. The ocean current power generation platform is firmly constructed because the energy of ocean flowing water is really indispensable when the flow speed of the ocean flowing water is more than three sections, the power generation platform is used as a main fixed point of the whole power generation system at sea and is also an acting point of a water turbine in the process of collecting the ocean current energy, and the ocean current power generation platform constructed in the deep water of more than thirty-five meters needs to be firmer and needs more steel. The firmness of the power generation platform is to bear the power generation power with the maximum flow speed and seventeen-grade strong typhoons, and the power generation platform can also be built on land, transported to a position for use on the sea, placed in the sea, and then piled and fixed on the periphery.

The inner and outer axes, the bracket, the hydraulic pump core barrel and the blades are assembled together to form the integral water turbine.
The water turbine can be lifted away from the water surface for working when the running water rises to the highest or retreats to the lowest and stops flowing for a few minutes, but the water turbine can be lifted and submerged for construction when the flow speed is weak within one hour. The outer axle center of the water turbine can be provided with a multi-pipe hydraulic pump which sinks into the seabed together with the water turbine to work. The lower edge of the blade of the water turbine is about one meter away from the ground, the upper edge of the blade of the water turbine is about ten meters away from the water surface, the normal work of the water turbine is not influenced by large waves when typhoons occur, and the flowing water is more urgent to generate more power about ten days before and after the typhoons arrive under the general condition. The water turbine rotates for four minutes at two times of flow speed, and rotates for about twelve minutes at the most rapid time of flow speed. The hydraulic pump can normally deliver energy when the hydraulic turbine rotates forwards and reversely when the tide is ebb. The total weight of the inner and outer axes of the small water turbine, the bracket, the core cylinder of the hydraulic pump and the blades is about 80 tons.
The working principle of the water turbine power generation is as follows:

The maximum adjustment is between twenty-six and forty degrees. When blades of the water turbine are installed, the multi-pipe hydraulic pump is also installed on an outer shaft center of the water turbine, and the water turbine is installed; the bracket is put into water along the square pile through the chute, the ocean current pushes the water turbine to rotate, and the outer axle center of the water turbine drives the hydraulic pump to rotate to work.

At present, in a new Port island sea area of Haikou city in Hainan province, sea current power generation test projects select seawater as a power generation medium.
The hydraulic pump can produce a plurality of independent output pipes. Wherein, the pump body of the multi-pipe hydraulic pump is designed into a circular shape.
The multi-pipe hydraulic pump has a diameter of two points and five meters, an inner diameter of about two points and one meter, twenty-four pump pipes are arranged around the multi-pipe hydraulic pump, a piston pump handle capable of pushing pump water is arranged below the pump pipes, a circular wheel which rotates along with the axis of the water turbine is arranged at about two meters, and ten cams are arranged around the circular wheel, as shown in fig. 5.
Wherein, when the flowing water promoted the hydraulic turbine and rotated, ten cams promoted every pump handle at different time points and carry out the pumping work, and the hydraulic turbine rotates a week, and ten cams just promote every hydraulic pump handle pumping ten times, because the time point that promotes pump handle work most pumping is different, have alleviateed the load of hydraulic turbine greatly, consequently do not just need the gearbox with the multitube hydraulic pump, when accumulator pressure reached two hundred kilograms, the hydraulic turbine also can easily be with the electricity generation medium input energy storage ware. Because the pump pipes are more, the water pumping quantity is very large. If the hydraulic turbine is large and twenty-four pump pipes are not enough, one more multi-pipe hydraulic pump can be installed. Or the pump body can be enlarged, more pump pipes are arranged, and more cams are arranged.
The multi-pipe hydraulic pump has the advantages that the strength of the water turbine is reduced without a gearbox, most pump pipes are different in time points when the water pump works, the water turbine only uses the force of ten pumps when all water pumps pump water for two hundred and forty times in one rotation of the water turbine, and the water turbine only has ten cams for cyclic use and light load, so that the medium and large water turbines can be provided with two three or more multi-pipe hydraulic pumps connected in parallel according to actual needs. The pump body can be enlarged, more pump pipes can be arranged, and more cams can be arranged.
The working principle of the energy accumulator is as follows:
if the water turbine directly generates electricity with the electric ball, the electricity can be generated when the flow speed is high, but when the water turbine has low flow speed and little force, the water turbine can drag the electric ball to waste energy, and the voltage and the current are unstable due to the unstable influence of the flow speed of wind waves, so that the unstable and uneven kinetic energy of the water turbine needs to be converted into uniform and stable pressure energy through the energy accumulator. The hydraulic pump is driven by the water turbine to output power generation energy, and when the power generation pressure is stored to eighty kilograms, the energy accumulator releases energy to push the hydraulic motor to rotate so as to drive the electric ball to generate power. When the speed of the water turbine is high and the electric ball is not used completely, the energy accumulator stores the energy, the pressure gauge displays that the pressure rises, when the speed of the water turbine is low and the electric ball is not moved, the stored energy is automatically fed back to cooperate with normal power generation, when the water turbine is not moved and the energy cannot be generated, the stored energy can be fed back to normally generate power, and the power generation time depends on the size of the energy accumulator and the amount of the stored energy. The energy accumulator is produced according to actual needs when the energy accumulator is used for large-scale production and power generation. The large-scale energy accumulator is a seamless steel tube which can bear three hundred kilograms of pressure and can be horizontally installed and used in parallel. An air compression steel pipe is arranged on one side of the seamless steel pipe of the energy accumulator, and because the air has lighter specific gravity than seawater, the air is compressed in the air compression pipe of the energy accumulator along with the increase of pressure in the energy accumulation process. Under the condition of pressure, the sea water has no elasticity, and the air elasticity is very large, so that when no water flows and the water turbine can not supply energy, the energy stored by the energy accumulator can be completely fed back to generate electricity, and if no compressed air is available, the energy can not be completely fed back to generate electricity. If the air pressure is not enough, the air compressor can be used for supplementing proper air. The working principle of the energy accumulator is that the energy accumulator has the functions of buffering, energy storage, voltage stabilization and control, no matter the flow speed is high or low, energy is not wasted, voltage stabilization power generation of a ball is guaranteed, and all energy of the energy accumulator can be fed back to generate power when the water turbine does not have energy to be transmitted, so that a large energy accumulator can accurately provide a power supply plan in advance.

Wherein, in terms of energy conversion:
1. energy conversion of the external engine: the external machine is a boiler produced by steel, and the coal or petroleum is fired to burn out uneven and unstable heat energy, so that the boiler generates even and stable pressure (i.e. the uneven and unstable heat energy is converted into even and stable pressure energy), and the locomotive or ship is driven by the even and stable pressure to run (i.e. the machine energy is a few horsepower), and the electric ball is driven by the machine to generate electricity (i.e. the electric energy is a few kilowatts per hour). Energy conversion principle of external engine: that is, the uneven and unstable heat energy is converted into the even and stable pressure energy, the even and stable pressure energy is converted into the even and stable kinetic energy, and the even and stable kinetic energy is converted into the electric energy.

Conversion principle of energy of internal combustion engine: that is, the uniform and stable oil injection quantity is used to ignite and explode to generate uniform and stable pressure energy, the uniform and stable pressure energy is converted into uniform and stable kinetic energy, and the kinetic energy is converted into electric energy.

The principle of ocean current energy conversion is as follows: the water turbine converts the kinetic energy of uneven and unstable ocean current and ocean current into uniform and stable pressure energy, the uniform and stable pressure energy is converted into uniform and stable kinetic energy, and the kinetic energy is converted into electric energy. The energy conversion principle of ocean power generation is the same as that of external and internal engines.

In the aspect of ocean current power generation large-scale production, because the distance from the sea to the land is far, two power transmission schemes can be adopted:
the first scheme is as follows: the platform is generated by three hundred sixty volt or four hundred seventy volt electric balls, after a plurality of single platforms generate electricity, a high-voltage line is pulled from a high-voltage tower built on the sea or submarine cables are used for power transmission and networking in parallel, and because the cost is very high when the platform is too far away from the land, a small energy accumulator, a hydraulic motor and the electric balls are installed on the top of the power generation platform, the maintenance and the repair are inconvenient, and the management is not good when typhoon exists, so the second scheme is adopted as the best choice: the high-voltage cable pipe replaces a submarine cable or a high-voltage wire, the energy of a plurality of power generation platforms is transmitted to the large energy transmission pipe through the small energy transmission pipe, the large energy transmission pipe is directly connected to a large energy accumulator, a hydraulic motor and an electric ball on the land and is installed on the land, the plurality of platforms on the sea are connected in parallel to transmit large energy, the plurality of hydraulic motors and the plurality of electric balls can be installed on the land according to needs, the device is very convenient and flexible, and the generated power is directly transmitted to a transformer substation for voltage transformation networking. Due to the regulation and control of the energy accumulator, the ocean current power generation can be accurately calculated in advance to the power supply plan of every hour, every day, every month and every year.
Proved by tests of more than six years by our team, one power generation platform is the same as an internal combustion engine on the land, and a hydraulic motor and an electric ball are the same as a set of power generation unit on the land.
