Description

Technical Field

[0001] The present invention relates to the technical field of ocean energy utilization, and particularly to an ocean platform power generation device based on multi-energy fusion technology. Background Art

[0002] Ocean current power generation is a renewable energy technology that converts the kinetic energy of water flow in the ocean into electrical energy. The working principle of ocean current power generation is to install a specially designed turbine device on the seabed or underwater, and use the power of the water flow to rotate the turbine and drive a speed reduction motor to generate electrical energy.

Among them, the invention patent with the publication number CN115013228B discloses a wave energy and temperature difference energy power generation device, including a floating platform, a speed reduction motor, a telescopic pipe, a semiconductor power generation cylinder, and at least one duck-type wave energy conversion device. The duck-type wave energy conversion device is fixed around the speed reduction motor at the edge of the floating platform. The speed reduction motor is installed at one end of the floating platform. The duck-type wave energy conversion device is electrically connected to the speed reduction motor. The duck-type wave energy conversion device is used to convert wave energy into electrical energy. The output shaft of the speed reduction motor is drivingly connected to one end of the telescopic pipe fixed on the floating platform. The other end of the telescopic pipe is fixedly connected to the semiconductor power generation cylinder. The telescopic pipe is used to drive the semiconductor power generation cylinder to move away from or close to the floating platform under the drive of the speed reduction motor to adjust the ocean depth where the semiconductor power generation cylinder is located. The semiconductor power generation cylinder is used to convert temperature difference energy into electrical energy. There are still some deficiencies in the use of this technical solution. It cannot enable the tidal current power generation device to make full use of tidal current energy for power generation. Moreover, the sea waves and tides on the sea fluctuate constantly. When the waves are large or the tide is rising, the tidal current power generation device is easily submerged by the sea waves, resulting in the tidal current power generation device being unable to fully absorb and convert tidal current energy, and at the same time, it will also affect the stability of the power production system.

[0040] A marine platform power generation device based on multi-energy fusion technology in this embodiment. An evaporator, a generator, and a steam turbine form a closed-cycle power generation system. The kinetic energy of the tidal current is converted by an energy absorption mechanism to drive the suction assembly to act, and the surface warm seawater is sent to the evaporator. The surface warm seawater is used to heat the low-boiling refrigerant flowing into the evaporator, causing it to evaporate and gasify. The steam then drives the steam turbine to rotate and drive the generator to generate electricity. The exhausted refrigerant gas after power generation is introduced into the heat exchanger of the cooling device, and the exhausted refrigerant gas is condensed using the coldness of the deep seawater, making it turn back into a liquid refrigerant again. The condensed refrigerant is pumped back to the evaporator and is heated and evaporated by the warm seawater again, forming a cycle. Among them, the working mode of the energy absorption mechanism is as follows: The tidal current pushes the undulating wheel to rotate, which in turn drives the special-shaped shaft to rotate between the two support disks. The two U-shaped joints of the special-shaped shaft act on the piston rod through the linkage rods respectively. When one linkage rod provides a thrust to the piston rod of the suction assembly it is connected to, the other linkage rod synchronously provides a pull force to the piston rod of the suction assembly it is connected to. This pushing and pulling process continuously cycles with the rotation of the special-shaped shaft. Taking one of the suction assemblies as an example, when the piston rod is subjected to a pulling force, the piston rod pulls the piston disk to move, the air chamber shrinks, the water chamber expands, and the one-way valve at the water inlet opens. The water chamber extracts the surface warm seawater through the pipeline connected to the water inlet. When the piston rod is subjected to a thrust, the piston rod pushes the piston disk to move, the air chamber expands, the water chamber shrinks, the one-way valve at the water inlet closes, and the one-way valve at the water outlet opens. The surface warm seawater in the water chamber flows into the evaporator through the pipeline connected to the water outlet. During this process, the actions of the other suction assembly are opposite. During the continuous rotation of the special-shaped shaft, the two suction assemblies cooperate to continuously supply the surface warm seawater to the evaporator. The continuous water supply can continuously heat the refrigerant flowing into the evaporator, avoiding the damage to the equipment caused by the vacuum degree fluctuation. In the closed cycle, a stable vacuum environment enables the seawater to boil at a low temperature, reducing energy loss. By stabilizing the water flow and optimizing the heat cycle, efficient and stable energy output is achieved. Combining bionic design and solar drive, this technology is both environmentally friendly and economical, especially suitable for remote islands and offshore platforms, providing an innovative solution for ocean energy development.

[0041] A power generation device for an offshore platform based on multi - energy fusion technology in this embodiment. During the operation of the piston disk of the suction assembly at a set frequency, the intake and exhaust valves are in the open state, and the air chamber is connected to the outside. When the kinetic energy provided by the tidal current is strong, that is, when the piston disk of the suction assembly exceeds the set frequency, the intake and exhaust valves close. During the expansion of the air chamber under the action of the piston disk, the check valve at the intake port opens, and the air chamber inhales outside air through the intake port. During the contraction of the air chamber, the air pressure in the air chamber increases, the check valve at the intake port closes, and the check valve at the outlet port opens. The pressurized air is input into the high - pressure tank through the pipeline connected to the outlet port. When the kinetic energy provided by the tidal current is weak and the evaporator cannot obtain sufficient surface warm seawater through the suction assembly, the valve at the outlet end of the high - pressure tank opens, and the high - pressure warm air in the high - pressure tank is sent into the evaporator. The high - pressure warm air is used to heat the low - boiling - point refrigerant flowing into the evaporator, causing it to evaporate and gasify. The steam then drives the steam turbine to rotate and drive the generator to generate electricity. The exhausted refrigerant gas after power generation is introduced into the heat exchanger of the cooling device and condensed using the coldness of the deep - seawater, making the exhausted refrigerant gas become liquid refrigerant again. The condensed refrigerant is pumped back to the evaporator and heated and evaporated again by the high - pressure warm air, forming a cycle. The combination of compressed - air energy storage and ocean - thermal - energy - conversion power generation heat exchange makes the power - generation process more stable, improves the net power generation, and enhances the power - generation efficiency. Through energy complementarity, equipment coordination, and technology integration, multiple goals of efficiency improvement, stability enhancement, cost reduction, and environmental friendliness are achieved.

[0042] A power generation device for an offshore platform based on multi - energy fusion technology in this embodiment. An induction device for monitoring the tidal - current direction is installed outside the energy - absorption mounting seat. When the induction device monitors a change in the tidal - current direction, the reduction motor operates. Through the cooperation of the gear and the internal tooth surface, the rotating ring and the mounting ring are driven to rotate relative to the lower - layer platform, and the components installed on the energy - absorption mounting seat also turn accordingly. When the undulating wheel of the energy - absorption assembly turns to a position perpendicular to the tidal current, the reduction motor stops working. Since the size of the tidal current will change the water level near the energy - absorption assembly, and the kinetic energy required for the rotation of the undulating wheel of the energy - absorption assembly is provided by the tidal current, in order to absorb tidal - current energy as much as possible, it is necessary to adjust the height of the undulating wheel to adapt to the change in water level. When the water level rises, the hydraulic cylinder retracts, pulling the support arm and raising the end of the support arm away from the hinge, causing the energy - absorption assembly to rise. When the water level drops, the hydraulic cylinder extends, pushing the support arm and lowering the end of the support arm away from the hinge, causing the energy - absorption assembly to lower. Through steering control and lifting control, the undulating wheel can face the tidal current, the impact force of the tidal current on the undulating wheel is more uniform, avoiding the energy dispersion caused by turbulence, maximizing the utilization of the impact force of the tidal current, and improving the energy - conversion efficiency. By matching the tidal - current direction and flow - velocity distribution in real - time, the energy - capture efficiency can be significantly improved. At the same time, the system stability and lifespan are enhanced.

[0043] The above embodiments shall not limit the present invention in any way, and all technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
