Description

Technical Field

[0002] At present, most fishing boats and merchant ships are driven by fuel. The fuel-driven method causes great environmental pollution and poor economy. The electrified drive method has the advantages of less pollution and good economy. Therefore, the electrification of fishing boats and merchant ships is the future development trend.

[0003] Currently, ships using the electrified drive method are mainly charged through fixed energy supply devices. These energy supply devices are generally installed on the shore or at fixed positions on sea lanes. The energy supply devices at sea mainly generate electricity and store energy through wind power and solar energy to provide electric energy for ships. However, the fixed-position energy supply devices can only wait for the ships to sail over by themselves for charging, and cannot provide timely rescue for ships with exhausted power. Moreover, the fixed energy supply devices are easily damaged by bad weather, and have the defects of inconvenient use and high damage rate. Summary of the Invention

[0039] Referring to Figure 1 , a schematic structural diagram of an energy supply device in an embodiment of the present application is shown. The energy supply device can be applied to the sea or a river and includes a hull 100, a power generation mechanism 200, a compression mechanism 300, an energy storage mechanism 400, a power transmission mechanism 500 and a self-driving mechanism 600. The hull 100 is provided with a cabin 100A. The power generation mechanism 200 is installed on the hull 100. The compression mechanism 300 is disposed in the cabin 100A. The compression mechanism 300 is electrically connected to the power generation mechanism 200. The energy storage mechanism 400 is connected to the hull 100. The energy storage mechanism 400 is connected to the compression mechanism 300. The power transmission mechanism 500 is disposed in the cabin 100A. The power transmission mechanism 500 is connected to the energy storage mechanism 400. The self-driving mechanism 600 is disposed on the hull 100. The power generation mechanism 200 and / or the power transmission mechanism 500 are electrically connected to the self-driving mechanism 600.

[0040] In an exemplary embodiment, as Figure 1 shown, the energy storage mechanism 400 is movably connected to the bottom of the hull 100. Since the energy storage mechanism 400 is used to store compressed air, the energy storage mechanism 400 is disposed underwater at the bottom of the hull 100. By changing the depth of the energy storage mechanism 400 underwater, the external pressure of the energy storage mechanism 400 can be changed, and the water pressure is used to assist the energy storage mechanism 400 to store high-pressure gas, thereby changing the gas storage pressure of the energy storage mechanism 400.

[0041] In the energy supply device described in the embodiment of the present application, the power generation mechanism 200 is disposed on the hull 100. The power generation mechanism 200 generates electricity through wind energy, light energy and wave energy. The power generation mechanism 200 can directly charge the ship, and the power generation mechanism 200 can also provide electric energy for the compression mechanism 300, so that the compression mechanism 300 compresses air into high-pressure gas and transmits the high-pressure gas into the energy storage mechanism 400 for storage. When the ship needs to be charged, the high-pressure gas in the energy storage mechanism 400 is transmitted to the power transmission mechanism 500, and the power transmission mechanism 500 converts the high-pressure energy of the high-pressure gas into electric energy, thereby charging the ship. By further providing a self-driving mechanism 600 on the hull 100, the self-driving mechanism 600 can obtain electric energy from the power generation mechanism 200 and / or the power transmission mechanism 500 to drive the hull 100 to navigate in the water.

[0042] The energy supply device described in the embodiment of the present application can be used to directly charge the ship through the electric energy obtained by the power generation mechanism 200, or when the electric energy is surplus, it can be converted into high-voltage energy through the compression mechanism 300 and stored in the energy storage mechanism 400, so that it can be converted back into electric energy through the transmission mechanism 500 when electric energy is needed later, and the self-driving mechanism 600 can enable the energy supply device to sail in the water by itself. When the energy supply device is arranged near the island, the energy supply device can automatically sail to the island to provide electric energy, or automatically sail to the waterway to provide electric energy for the ship, and can also actively sail to the ship that has run out of energy to provide electric energy, which has a wider range of uses and a larger service scope. Moreover, when the ship's energy is exhausted, it can also automatically sail to the location of the ship for rescue, with a high degree of automation. When there is bad weather at sea, the energy supply device can automatically sail to avoid the bad weather and avoid damage to the device, which has the advantages of easy use and low damage rate.

[0043] Combination Figure 2 , shows a schematic diagram of the internal structure of the energy supply device in an embodiment of the present application. In some embodiments, the compression mechanism 300 includes a first drive unit 310, a low-pressure compressor 320, a first cooler 330, a high-pressure compressor 340 and a second cooler 350. The first drive unit 310 is electrically connected to the power generation mechanism 200. The power output end of the first drive unit 310 is connected to the low-pressure compressor 320 and the high-pressure compressor 340. The low-pressure compressor 320, the first cooler 330, the high-pressure compressor 340 and the second cooler 350 are sequentially connected to form a gas compression channel through the first gas pipeline 360. The compressed gas output end 301 of the gas compression channel is connected to the energy storage mechanism 400. It should be noted that the exhaust pressure of the low-pressure compressor 320 is 1-10MPa, and the exhaust pressure of the high-pressure compressor 340 is 100-1000MPa.

[0044] In this embodiment, the first driving unit 310 drives the low-pressure compressor 320 to work, compressing the air in the atmosphere into compressed gas, and then transporting the compressed gas to the first cooler 330 through the first gas pipeline 360 ​​to cool the compressed gas, and then transporting it to the high-pressure compressor 340 to further compress the compressed gas, and then inputting the high-pressure compressed gas into the second cooler 350 for cooling, and finally transporting the high-pressure compressed gas to the energy storage mechanism 400 for storage. In this embodiment, high-pressure compressed gas is obtained by staged compression and cooling, so that the energy supply device has high energy utilization efficiency.

[0045] In an exemplary embodiment, Figure 2As shown, the low-pressure compressor 320 is connected to the first drive unit 310 by a shaft, and the high-pressure compressor 340 is also connected to the first drive unit 310 by a shaft. Moreover, the low-pressure compressor 320 and the high-pressure compressor 340 are coaxially arranged. The first drive unit 310 can synchronously drive the low-pressure compressor 320 and the high-pressure compressor 340 to compress air, making the structure of the compression mechanism 300 more concise.

[0046] In an exemplary embodiment, the first drive unit 310 is an electric motor. After obtaining the electric energy of the power generation mechanism 200, the electric motor can directly drive the electric motor to work, so that the electric motor drives the low-pressure compressor 320 and the high-pressure compressor 340 to work.

[0047] In an alternative embodiment, as Figure 2 shown, the power transmission mechanism 500 includes a first heater 510, a high-pressure expander 520, a second heater 530, a low-pressure expander 540, and a power generation unit 550. The power output ends of the high-pressure expander 520 and the low-pressure expander 540 are both connected to the power generation unit 550. The first heater 510, the high-pressure expander 520, the second heater 530, and the low-pressure expander 540 are sequentially connected through a second gas transmission pipeline 560 to form a gas expansion channel. The compressed gas input end 501 of the gas expansion channel is connected to the energy storage mechanism 400. It should be noted that the inlet pressure of the high-pressure expander 520 is usually relatively high, generally between 5 MPa and 20 MPa or even higher, and the outlet pressure is generally about 1 MPa to 5 MPa, and it can adapt to a large pressure drop. The inlet pressure of the low-pressure expander 540 is below 1 MPa or even lower, and its outlet pressure is usually about 0.1 MPa to 0.5 MPa or even lower.

[0048] In this embodiment, the compressed gas of the energy storage mechanism 400 is input into the first heater 510 for heating, and then the heated compressed gas is input into the high-pressure expander 520 to drive the high-pressure expander 520 to do work. Then, the compressed gas after further work is further input into the second heater 530 for heating, and after heating, it is input into the low-pressure expander 540 to drive the low-pressure expander 540 to do further work. The high-pressure expander 520 and the low-pressure expander 540 do work to drive the power generation unit 550 to generate electricity. In this embodiment, through staged heating and expansion work, the potential energy of the compressed gas is fully utilized, making the energy utilization efficiency of the energy supply device high.

[0049] In an exemplary embodiment, as Figure 2As shown, there is a shaft connection between the high-pressure expander 520 and the power generation unit 550, and there is also a shaft connection between the low-pressure expander 540 and the power generation unit 550. Moreover, the high-pressure expander 520 and the low-pressure expander 540 are coaxially arranged, and the high-pressure expander 520 and the low-pressure expander 540 can synchronously drive the power generation unit 550 to generate electricity, making the structure of the power transmission mechanism 500 more concise.

[0050] In an exemplary embodiment, the power generation unit 550 is a generator, and the generator generates electricity under the drive of the high-pressure expander 520 and the low-pressure expander 540, thereby outputting electric energy.

[0051] It should be noted that during the stage when the power transmission mechanism 500 converts the high-pressure energy of the high-pressure gas into electric energy, the compressed air in the energy storage mechanism 400 is heated by the heat storage mechanism 700 to improve the efficiency of the high-pressure expander 520 and the low-pressure expander 540. The high-pressure air after increasing the temperature is depressurized in sequence through the high-pressure expander 520 and the low-pressure expander 540, converting the internal energy into kinetic energy, and then the power generation unit 550 converts the kinetic energy into electric energy. Specifically, the principle of the expansion work of the compressed gas is mainly based on relevant theories such as the first law of thermodynamics and the ideal gas state equation. When the compressed gas expands in the high-pressure expander 520 and the low-pressure expander 540, the distance between molecules increases, and the molecules have more space to move. The intensity of the molecular thermal motion relatively weakens, and the average kinetic energy of the molecules decreases. The reduction of this part of the energy is manifested as doing external work. That is to say, when the compressed gas expands in the high-pressure expander 520 and the low-pressure expander 540, the molecules impact and push the components of the compressed gas in the high-pressure expander 520 and the low-pressure expander 540 to move, which is the process of converting molecular energy into mechanical energy.

[0052] In an alternative embodiment, as Figure 1 and Figure 2 shown, the energy storage mechanism 400 includes a first valve 410, a second valve 420, a third gas transmission pipeline 450, a gas storage tank 430, and a first connecting member 440. The third gas transmission pipeline 450 is provided with a first port and a second port. The compressed gas output end 301 is connected to the first port through the first valve 410, and the compressed gas input end 501 of the gas expansion channel is connected to the first port through the second valve 420. The second port is connected to the gas storage tank 430. One end of the first connecting member 440 is connected to the hull 100, and the other end of the first connecting member 440 is connected to the gas storage tank 430. Among them, both the first valve 410 and the second valve 420 are gas valves.

[0053] In this embodiment, the compressed gas output end 301 and the compressed gas input end 501 are connected to the gas storage tank 430, and the opening and closing of the gas compression channel are controlled by the first valve 410, and the opening and closing of the gas expansion channel are controlled by the second valve 420. When the gas storage tank 430 is in the gas storage state, the first valve 410 and the second valve 420 are in the closed state; when it is necessary to input compressed gas for storage, the first valve 410 is opened and the second valve 420 is closed; when it is necessary to output compressed gas for power generation, the first valve 410 is closed and the second valve 420 is opened. Since the gas storage tank 430 is placed underwater, the first connecting member 440 is required to connect the gas storage tank 430 to the hull 100. Storing compressed air underwater, away from the hull 100 and the personnel activity area of the offshore energy supply device, reduces the safety risks that may be brought about by compressed air leakage or explosion. Moreover, the underwater environment is relatively stable, with small temperature and pressure changes, which is conducive to the safe storage of compressed air, reduces the occurrence probability of safety accidents such as fires and explosions, and improves the overall safety of the energy supply device.

[0054] In an exemplary embodiment, as Figure 1 shown, the first connecting member 440 is a telescopic chain. One end of the telescopic chain is connected to the hull 100, and the other end of the telescopic chain is connected to the gas storage tank 430. The depth of the gas storage tank 430 underwater can be changed through the telescopic chain, so as to conveniently balance the pressure inside and outside the gas storage tank 430, and the depth of the gas storage tank 430 can be adjusted according to the energy storage capacity, which has the advantage of convenient use.

[0055] In an alternative embodiment, the lower part of the gas storage tank 430 is provided with a water inlet and a water outlet. Through the principle of gas-water mutual drive, when storing energy, the compressed gas squeezes the water out of the gas storage tank 430, and when releasing energy, the water enters the gas storage tank 430 to drive the compressed gas output, realizing constant-pressure energy storage, with a large energy storage capacity and high efficiency. Specifically, when storing energy, the water outlet is opened and the water inlet is closed, and the compressed gas enters the gas storage tank 430 to drive the seawater in the tank away through the water outlet, realizing the storage of compressed gas in the gas storage tank 430; when releasing energy, the water outlet is closed and the water inlet is opened, and the high-pressure seawater enters the gas storage tank 430 from the water inlet to drive the compressed gas out of the gas storage tank 430, realizing the release of energy.

[0056] In an alternative embodiment, as Figure 1 and Figure 2As shown, the energy supply device further includes a heat storage mechanism 700. The heat storage mechanism 700 is arranged in the cabin 100A. The heat storage mechanism 700 includes a cold water tank 710, a cold water pump 720, a hot water tank 730 and a hot water pump 740. The first cooler 330 is provided with a first water inlet and a first water outlet. The second cooler 350 is provided with a second water inlet and a second water outlet. The first heater 510 is provided with a third water inlet and a third water outlet. The second heater 530 is provided with a fourth water inlet and a fourth water outlet. The cold water tank 710 is connected to the first water inlet and the second water inlet through the cold water pump 720. The first water outlet and the second water outlet are connected to the hot water tank 730. The hot water tank 730 is also connected to the third water inlet and the fourth water inlet through the hot water pump 740. The third water outlet and the fourth water outlet are connected to the cold water tank 710. It should be noted that each component of the heat storage mechanism 700 is connected through a water pipe.

[0057] In this embodiment, by setting the cold water tank 710 and the hot water tank 730, during energy storage, the cold water in the cold water tank 710 is respectively transmitted into the first cooler 330 and the second cooler 350 through the cold water pump 720, so that the cold water in the first cooler 330 and the second cooler 350 exchanges heat with the compressed gas. The hot water obtained after heat exchange is input into the hot water tank 730. During energy release, the hot water in the hot water tank 730 is respectively transmitted into the first heater 510 and the second heater 530 through the hot water pump 740, so that after the first heater 510 and the second heater 530 heat and expand the compressed gas, the heat-exchanged water is then transported back to the cold water tank. The temperature of the compressed high-pressure air will increase. By setting the heat storage mechanism 700 to cool the compressed air during energy storage, the temperature of the compressed air can be prevented from being too high to damage the gas storage tank 430, ensuring the stability of the energy supply device and reducing the damage rate.

[0058] In an exemplary embodiment, the water temperature in the cold water tank 710 is between 30 - 40 °C. After passing through the first cooler 330 and the second cooler 350, the water temperature becomes about 130 °C and then enters the hot water tank 730.

[0059] In an exemplary embodiment, the first cooler 330, the second cooler 350, the first heater 510 and the second heater 530 are plate fin heat exchangers, and the plate fin heat exchanger has the advantage of high heat transfer efficiency.

[0060] In an alternative embodiment, as Figure 2As shown, the heat storage mechanism 700 further includes a seawater desalination component 750 and a heat and cold conversion component 760. The third water outlet and the fourth water outlet are both connected to the seawater desalination component 750. The seawater desalination component 750 is connected to the heat and cold conversion component 760, and the heat and cold conversion component 760 is connected to the cold water tank 710. When the energy supply device is set at sea, by setting the seawater desalination component 750 and the heat and cold conversion component 760, the hot water output by the second heater 530 can be processed into desalinated water in the seawater desalination component 750, and the heat and cold conversion component 760 can provide heat energy or cold energy for the hull 100, improving the convenience of use of the energy supply device.

[0061] In an alternative embodiment, as Figure 2 shown, the heat storage mechanism 700 further includes a third valve 770 and a fourth valve 780. The third valve 770 is connected in series to the water pipe at one end of the input seawater desalination component 750, and the fourth valve 780 is connected in parallel with the third valve 770 and the seawater desalination component 750. By setting the third valve 770 and the fourth valve 780, the hot water discharged from the second heater 530 can first enter the seawater desalination component 750 and then enter the heat and cold conversion component 760, or can directly enter the heat and cold conversion component 760 without passing through the seawater desalination component 750, having the advantage of convenient use.

[0062] In an exemplary embodiment, the discharge water temperature of the second heater 530 is 90 °C. After the 90 °C hot water enters the seawater desalination component 750 to produce fresh water, it drops to 80 °C and then enters the heat and cold conversion component 760. In the north, the heat and cold conversion component 760 can be a plate heat exchanger or a shell and tube heat exchanger, and the generated heat energy is used for heating and providing domestic hot water; in the south, the heat and cold conversion component 760 can be a thermally driven ammonia refrigerating machine, which can make ice and refrigerate, provide finished ice for fishing boats, and at the same time provide cold energy for the hull 100.

[0063] In an exemplary embodiment, the seawater desalination component 750 is a thermal seawater desalination device, which is a device that heats seawater to evaporate it and then condenses the steam into fresh water. Specifically, the thermal seawater desalination device is a device for low-temperature multi-effect distillation seawater desalination. The low-temperature multi-effect distillation seawater desalination technology refers to a seawater desalination technology in which the highest evaporation temperature of the brine is about 70 degrees Celsius. Its characteristic is that a series of horizontal tube falling film evaporators are connected in series and divided into several effect groups, and a certain amount of steam input is used for multiple evaporation and condensation to obtain distilled water several times the amount of the heating steam.

[0064] In an optional embodiment, the self-driving mechanism 600 includes a second driving unit 610 and a thruster 620. Both the second driving unit 610 and the thruster 620 are installed on the hull 100. The power generation mechanism 200 and / or the power transmission mechanism 500 are electrically connected to the second driving unit 610, and the power output end of the second driving unit 610 is connected to the thruster 620. By setting the second driving unit 610 to drive the thruster 620 to work, the energy supply device can be controlled to move on the water, so that the energy supply device can automatically sail to a designated location to serve ships, expanding the service range of the energy supply device. Moreover, it can automatically sail to avoid areas with bad weather, reducing the damage rate.

[0065] In an exemplary embodiment, the thruster 620 is a propeller, and the second driving unit 610 is an engine. The engine drives the propeller to rotate to generate a backward thrust, pushing the hull 100 forward. Its structure is simple and the efficiency is high.

[0066] In an optional embodiment, as Figure 1 shown, the power generation mechanism 200 includes a wave energy power generation component 210, a photovoltaic component 220 and a wind energy power generation component 230. The wave energy power generation component 210 is arranged at the end of the hull 100 in the forward direction, the photovoltaic component 220 is arranged on the upper surface of the hull 100, the hull 100 is provided with a telescopic rod 110, one end of the telescopic rod 110 is connected to the hull 100, and the other end of the telescopic rod 110 is connected to the wind energy power generation component 230. The power generation component, the photovoltaic component 220 and the wind energy power generation component 230 are all electrically connected to the first driving unit 310. By setting the wave energy power generation component 210, the photovoltaic component 220 and the wind energy power generation component 230, the wave energy, light energy and wind energy in nature are converted into electric energy for storage, and no greenhouse gas and pollutant emissions are generated during the operation process, resulting in less pollution to the marine environment. By adjusting the power generation mechanism 200, the energy supply device can optimize and integrate energy from different time periods and different sources, improving the energy utilization efficiency. Moreover, in this embodiment, a telescopic rod 110 is also provided to install the wind energy power generation component 230. During navigation or typhoon periods, the telescopic rod 110 can be retracted to avoid damage to the wind energy power generation component 230.

[0067] In an exemplary embodiment, the telescopic rod 110 is an electric telescopic rod, which can automatically extend and retract according to the environmental conditions to avoid damage to the wind energy power generation component 230.

[0068] In an exemplary embodiment, as Figure 2 shown, the deck of the hull 100 is provided with a house, and the photovoltaic component 220 is arranged on the top of the house.

[0069] In an exemplary embodiment, the wave energy power generation assembly 210 is used to convert ocean wave energy into electrical energy. The wave energy power generation assembly 210 consists of a fixed chamber communicating with seawater and a piston that can move up and down. When waves enter the chamber, they push the piston to move up and down, thereby compressing or expanding the air in the chamber, forming a high-pressure or low-pressure air flow, and driving an air turbine generator to generate electricity. The photovoltaic assembly 220 is used to directly convert solar energy into electrical energy. Its structure mainly includes photovoltaic panels and an inverter. The photovoltaic panels are used to absorb sunlight and generate direct current, and the inverter is used to convert the direct current generated by the photovoltaic panels into alternating current. The wind energy power generation assembly 230 is used to convert wind energy into electrical energy. Its structure mainly includes a wind turbine, a transmission system, and a generator. The wind power drives the wind turbine to rotate, and the transmission system transmits the mechanical energy of the rotating wind turbine to the generator for power generation.

[0070] In an alternative embodiment, as Figure 1 shown, the energy supply device further includes a load mechanism 800. The load mechanism 800 includes a first load member 810, a second connecting member 820, a second load member 830, and a third connecting member 840. One end of the second connecting member 820 is connected to the hull 100, and the other end of the second connecting member 820 is connected to the first load member 810. One end of the third connecting member 840 is connected to the gas storage tank 430, and the other end of the third connecting member 840 is connected to the second load member 830.

[0071] In this embodiment, by further providing the load mechanism 800, during the mooring operation of the energy supply device, the second connecting member 820 pulls the first load member 810 to be placed at an appropriate position underwater, thereby maintaining the position stability of the energy supply device, and the third connecting member 840 also pulls the second load member 830, thereby maintaining the position stability of the gas storage tank 430. When navigation is required, the first load member 810, the second load member 830, and the gas storage tank 430 will be retracted.

[0072] In an alternative embodiment, as Figure 1 shown, the main body part of the gas storage tank 430 is a cylinder, and one end of the cylinder in the first direction is smoothly connected to a hemispherical body or a conical body. It should be noted that the first direction is the direction of the forward navigation of the hull. By setting one end of the gas storage tank 430 in the navigation direction as a hemispherical body or a conical body, the navigation resistance of the gas storage tank 430 is reduced, and the energy consumption is reduced.

[0073] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
