Description

OFFSHORE ENERGY ISLAND APPARATUS TECHNICAL FIELD
[0001] The present disclosure relates to the field of shipbuilding and ocean engineering technology, and particularly to an offshore energy island apparatus.
BACKGROUND
[0002] Seas and oceans contain a tremendous amount of energy. The development and utilization of the marine resources, on one hand, can effectively improve the utilization rate of clean energy, and on the other hand, can also improve the capability of island construction and coastal defense. Meanwhile, the scientists and researchers have always been dedicating to studying how to develop and utilize the plenty of renewable resources contained in the seas and oceans. Offshore energy island apparatus, as an independent apparatus in the sea or ocean, can utilize the renewable marine energy to generate electricity for various electrical devices on the offshore energy island apparatus to use, and can produce energy storage substances or output energy. Nevertheless, due to the variety and the complexity of the marine environment, the power generation equipment based on one energy resource and common offshore energy island apparatus have the problems of unstable power output, high construction cost, and poor electricity generation.

The terms as used herein in the description of the present disclosure are for the purpose of describing particular embodiments only, and are not intended to limit the present disclosure. All of the technical features in the embodiments can be employed in arbitrary combinations. For purpose of simplifying the description, not all arbitrary combinations of the technical features in the embodiments illustrated above are described. However, as long as such combinations of the technical features are not contradictory, they should be considered as within the scope of the disclosure in the specification.
[00281 As shown in FIG. 1 to FIG. 3, an embodiment provides an offshore energy island apparatus 10 including an offshore platform 11, and a tidal energy electric power generator, a wave energy electric power generator, a photovoltaic electric power generator 14, a wind electric power generator 15, a hydrogen producing device 16 and a desalination device 17, which are all arranged on the offshore platform 11.
[0029] The tidal energy electric power generator, the wave energy electric power generator, the photovoltaic electric power generator 14, and the wind electric power generator 15 are electrically connected to the hydrogen producing device 16, and configured to supply power to the hydrogen producing device 16. The tidal energy electric power generator, the wave energy electric power generator, the photovoltaic electric power generator 14, and the wind electric power generator 15 are electrically connected to the desalination device 17, and are configured to supply power to the desalination device 17.
[0030] The processes of the desalination and the hydrogen production can be implemented by arranging the desalination device 17 and the hydrogen producing device 16 on the offshore platform 11, thereby increasing the variety of the products, and more greatly exerting the use of the energy island. Considering that the power generation based on only one energy source has a poor stability and a low energy density, the energy island apparatus fully exploits the various renewable marine resources through a combination of the tidal energy electric power generator, the wave energy electric power generator, the photovoltaic electric power generator 14, and the wind electric power generator 16, to provide electric power for the operation of the desalination device 17 and the hydrogen producing device 16. Specifically, the desalination device 17 uses the electric power to proceed the desalination. The obtained freshwater can be used, on one hand, for the routine life on the offshore platform 11, or for replenishing vessels at sea, and on the other hand, for producing fluid hydrogen by the hydrogen producing device 16. The hydrogen energy can be used for replenishing vessels, or can also be used as a carrier in converting for the electric power. Moreover, the electric power generated by each electric power generator can be stored up, or can be transmitted through underwater cables to electrical devices in nearby sea areas to use.
[00311 Furthermore, as shown in FIG. 1 and FIG. 3, in order to extend the application range of the offshore energy island apparatus 10, in an embodiment, the offshore platform 11 adopts a semi-submersible platform having a frame structure.
[0032] Specifically, as shown in FIG. 3, the offshore platform 11 includes a deck 111, a submerged frame 112, and support members supportively are arranged between the deck 111 and the submerged frame 112. The submerged frame 112 is located below the deck 111. In use, the submerged frame 112 is located in the sea water, and the deck 111 floats above the water surface of the sea.
[00331 Moreover, oscillating buoys 13 of the wave energy electric power generator are arranged on the support members, and horizontal-axis water turbines 12 are arranged on the submerged frame 112.
[0034] The wave energy electric power generator generates electric power when waves pass by the oscillating buoys 13. Meanwhile, a tidal surge causes the horizontal axis water turbine 12 to operate thereby generating electric power. The eventually generated electric power can be provided for the desalination device 17 or the hydrogen producing device 16 on the offshore platform 11, and can also be stored in an energy storage unit 1118 or for charging external devices. When a control center 18 is arranged on the offshore platform 11, the generated electric power can also be provided for each device of the control center 18 to use.
[0035] Specifically, in an embodiment, the horizontal-axis water turbine 12 can be a lift-type water turbine having fixed impeller blades. Moreover, the lift-type water turbine having the fixed impeller blades can also provide propulsion for a slight adjustment and a low-speed movement of the offshore platform 11.
[0036] Furthermore, as shown in FIG. I to FIG. 3, in an embodiment, the deck 111 can be a hexagonal plate. A hexagonal reinforcing structure formed by surroundingly arranging six upper side beams is disposed below the hexagonal plate. The support members are supportively arranged between the hexagonal reinforcing structure and the submerged frame. The upper side beam can further provide buoyancy for the deck 111 under the action of sea water. The submerged frame 112 is a hexagonal frame corresponding to the deck 111. The number of the support members is plural. The support members supportively arranged at corners of the hexagonal plate and the hexagonal frame are main support columns 113. The support members supportively arranged between the edges of the hexagonal frame and the upper side beams are side support beams 114. A plurality of side support beams 114 are respectively arranged on each edge of the hexagonal frame.
[00371 In this way, the weight of the offshore platform 11 is uniformly distributed, which improves the stability of the platform. Specifically, the tidal energy electric power generator, the wave energy electric power generator, the photovoltaic electric power generator 14, and the wind electric power generator 15 can be distributed uniformly on the deck 111.
[0038] Furthermore, the hexagonal plate and the hexagonal frame can be regular hexagonal structures.
[0039] Specifically, as shown in FIG. 1 and FIG. 3, the oscillating buoys 13 are arranged on the side support beams 114, and the horizontal-axis water turbines 12 are arranged on the edges of the hexagon frame.
[0040] Moreover, in an embodiment, as shown in FIG. 3, a pair of horizontal-axis water turbines 12 is arranged on each of two opposite edges of the hexagonal frame. Thereby, the horizontal-axis water turbines 12 can provide propulsion in two opposite directions during the slight adjustment and the low speed movement of the offshore platform 11.
[0041] The other four edges of the hexagonal frame are auxiliary edges. The oscillating buoys 13 are arranged on the side support beams 114 corresponding to the auxiliary edges. As the tidal energy electric power generator and the wave energy electric power generator both generate electric power from the energy transferred by the fluctuation of the sea water, the horizontal-axis water turbines 12 and the oscillating buoys 13 are arranged on different edges of the hexagonal frame, thereby reducing, as much as possible, the interference of the tidal energy electric power generator on the electric power generating process of the wave energy electric power generator.
[0042] Specifically, the oscillating buoy 13 is divided into a column portion and a sphere portion. The oscillating buoy 13 is coaxial with the side support beam 114.
[0043] As shown in FIG. 1, an inductive charger 1111 is arranged on a side edge of the deck 111 corresponding to the oscillating buoy 13, and the inductive charger 1111 can be configured to charge vessels passing by. Moreover, the inductive charger 1111 protrudes from the deck 111, thereby keeping the vessel away from the oscillating buoys 13 at a safe distance during the charging process. Moreover, a cushion member can be arranged on the inductive charger 1111 in order to increase the stability of the charging process and prevent damages caused by collision during the charging process. A magnetic resonance charging technique can be adopted in the inductive charger for charging the vessels.
[0044] The electric power generated by the oscillating buoys 13 and the electric power generated by the horizontal-axis water turbine 12 are transferred to the electrical devices on the deck 111 through cables arranged in the side support beams 114. When a rectifier 1116 is arranged on the deck 111, the cables are electrically connected to the rectifier 1116.
[0045] Further, in an embodiment, as shown in FIG. 2, the deck 111 is divided into six areas by diagonals as dividing lines. The six areas include three photovoltaic power generationareas 1112, an electrical substation area 1113, a hydrogen producing area 1114, and a desalination area 1115.
[0046] The three photovoltaic power generation areas 1112 are spaced apart from each other. The photovoltaic electric power generator 14 includes a plurality of photovoltaic panels distributed respectively in the three photovoltaic power generation areas 1112. A desalination workshop 171 and a pumping workshop 172 of the desalination device 17 are arranged in the desalination area 1115. A hydrogen producing station 161 and a hydrogen storage tank of the hydrogen producing device 16 and a water tank 173 of the desalination device 17 are arranged in the hydrogen producing area 1114.
[00471 Of course, in order to further improve the utilization of the areas, the photovoltaic panels can also be arranged on the roofs of the workshops of the desalination device 17 in the desalination area.
[0048] By dividing the deck 111 into the areas and appropriately arranging the devices into the areas, the offshore energy island apparatus 10 becomes more stable, and the ability to withstand winds and waves is improved. Moreover, considering that electric power and freshwater are required for the process of producing hydrogen, the water tanks 173 of the desalination device 17 and the hydrogen producing station 161, and the hydrogen storage tank 162 of the hydrogen producing device 16 are arranged in the same area, thereby facilitating the hydrogen producing process.
[0049] Specifically, as shown in FIG. 1 and FIG. 2, the hydrogen producing device 16 includes two hydrogen producing stations 161 and two hydrogen storage tanks 162. The two hydrogen producing stations 161 are arranged sequentially in a direction away from the edge of the deck 111. The two hydrogen storage tanks 162 and the water tank 173 are arranged sequentially in a direction away from the edge of the deck 111. The hydrogen producing stations 161 communicate with the hydrogen storage tanks 162 through pipelines. The desalination workshop 171 is connected with the water tank 173 through pipelines. The freshwater produced by the desalination workshop 171 is transferred to the water tanks 173 in an increased pressure under the action of the pumping workshop 172.
[0050] Further, as shown in FIG. 2, in order to facilitate transporting, a track 115 or a crane 116 can be arranged at the boundary between the hydrogen producing area 1114 and the adjacent photovoltaic power generation area 1112. The track 115 is arranged along the diagonal direction. The two hydrogen storage tanks 162 and the water tank 173 are adjacent to the track 115, thereby facilitating the transportation of the substances stored in the water tank 173 and the hydrogen storage tanks 162.
[0051] In order to facilitate draining accumulated water from the deck 111, as shown in FIG. 2, a drain outlet 117 can be arranged at each corner of the deck111. A bus channel is arranged along the diagonal of the deck 111, and is configured for passing the cables between the electric power generators and the power consuming devices.
[0052] A rectifier 1116, an inverter 1117 and an energy storage unit1118 electrically connected with each other are arranged in the electrical substation area 1113. The tidal energy electric power generator, the wave energy electric power generator, the photovoltaic electric power generator 14, and the wind electric power generator 15 are electrically connected to the rectifier 1116. The hydrogen producing device 16 and the desalination device 17 are electrically connected to the inverter 1117.
[0053] The electric power generated by each electric power generator can be transferred to the rectifier 1116 through the cables. The cables can be aggregated in the bus channel, which facilitates the maintenance. The electric power receives a frequency modulation through the rectifier 1116 and a voltage regulation through the inverter 1117, and is output to the hydrogen producing device 16 and the desalination device 17. Of course, when areas such as a living area and the control center 18 are also arranged on the deck 111, the electric power stabilized and output by the inverter 1117 can also be transferred to the power consuming devices in these areas. If underwater cables are arranged in the sea area of the offshore energy island apparatus 10, the electric power can also be transferred to the underwater cables.
[0054] Specifically, as shown in FIG. 1 and FIG. 2, the number of the rectifiers 1116 in the electrical substation area 1113 is eighteen, the number of the inverters 1117 in the electrical substation area 1113 is three, and the number of the energy storage units 1118 is six.
[0055] Moreover, the energy storage unit 1118 includes an energy storage frame, an energy storage cap and six lithium battery packs.
[00561 Further, as shown in FIG. 1, an angle between the photovoltaic panels arranged in different areas is 1200. The photovoltaic panels are inclined upwards, and an angle between the photovoltaic panels and the plane of the deck 111 is 45, such that the photovoltaic electric power generator 14 can collect light energy in different time periods.
[00571 Further, as shown in FIG. 1 and FIG. 2, a central control area 1119 is arranged at the center of the deck 111. A control center 18 is arranged in the central control area 1119. The control center 18 is electrically connected to the rectifiers 1116, the inverters 1117, the energy storage units 1118, the tidal energy electric power generator, the wave energy electric power generator, the photovoltaic electric power generator 14, the wind electric power generator 15, the hydrogen producing device 16, and the desalination device 17. The control center 18 is configured to regulate the energy storage and discharge of the energy storage units 1118 according to the amount of power generated by each electric power generator, and configured to monitor and control the states and the operation conditions of the devices on the energy island.
[00581 Further, as shown in FIG. 4, the control center 18, a living floor, and a bottom floor 19 are arranged sequentially from top to bottom in the vertical direction in the central control area 1119. Moreover, an elevator is further arranged for staff to use. The elevator includes a passenger elevator 195 and a freight elevator 194. A power supply house 192, a water supply house 193, and a server room 191 are arranged on the bottom floor 19. A power supply changeover panel is arranged in the power supply house 192. Water pipe changeover nodes and a master control valve are arranged in the water supply house 193. Servers are arranged in the server room 191.
[0059] As shown in FIG. 1 and FIG. 2, the deck 111 has three wind turbine areas. The three wind turbine areas are respectively located at three corners of the deck 111, and are spaced apart from each other. The wind electric power generator 15 includes three wind turbines arranged respectively in the three wind turbine areas. The wind turbines are electrically connected to the rectifiers 1116.
[0060] The three wind turbines are respectively arranged in the three wind turbine areas such that the load of the whole offshore platform 11 is uniform, which improves the ability to withstand winds and waves.
[00611 Further, as shown in FIG. 1 and FIG. 2, a helipad 118 and two crane areas are respectively located at the other three corners of the deck 111. One of the crane areas is located at the corner where the hydrogen producing area 1114 and the photovoltaic power generation area 1112 are joined, and the other crane area is located at the comer where the electrical substation area 1113 and the photovoltaic power generation area 1112 are joined. An inductive power supply device is arranged on the helipad, and is electrically connected to the inverters 1117.
[0062] The helipad 118 can be configured for take-off and landing of drones and helicopters. The inductive power supply device of the helipad 118 is configured for self charging of the drones. Moreover, the arrangement of the two crane areas facilitates the transport of the substances in the hydrogen producing area 1114 and in the electrical substation area 1113.
[00631 Specifically, as shown in FIG. 1 and FIG. 2, a crane 116 is arranged in the crane area, and a track 115 configured for moving the crane 116 is arranged on the deck 111. One end of the track 115 approaches the crane area, and the other end of the track 115 extends along the diagonal of the deck 111 in a direction towards the center of the deck 111. Thereby, the crane 116 can travel along the track 115 to transport the nearby substances.
[0064] Further, as show in FIG. 1 and FIG. 2, the lithium battery packs in the three energy storage units 1118 that are adjacent to the track 115 of the six energy storage units 1118 are detachable to replenish the passing vessels.
[00651 Specifically, as shown in FIG. 5, the track 115 has a T-shape. The T-shaped track includes a bearing plate 1151 and a support bar 1152. The support bar 1152 is supportively arranged between the bearing plate 1151 and the deck 111. The support bar 1152 and the bearing plate 1151 are arranged along the diagonal. A bottom plate 1161 is arranged at the bottom of a support column of the crane 116. A bearing roller 1162 is arranged between the bottom plate 1161 and the T-shaped track 115, and is configured to support the bottom plate 1161. Two vertical plates 1163 are located at two sides of the bottomplate 1161 and opposite to each other. Aholding roller 1164 is located at inner sides of the vertical plates 1163. The holding roller 1164 is located under the bearing plate 1151, and cooperatively limit the position with the bearing roller, thereby ensuring that the crane 116 can travel along the track 115. Moreover, considering that the offshore energy island apparatus 10 located may sway slightly at the water surface, the holding roller 1164, the vertical plate 1163, the bottom plate 1161, and the bearing plate 1162 can cooperatively make the crane 116 reliably stand on the deck 111.
[00661 Furthermore, the offshore energy island apparatus 10 further includes six pontoons (not shown). First tethers are arranged between the pontoons and the main support column, and second tethers are arranged on the pontoons to connect the sea floor.
[00671 As shown in FIG. 3, in an embodiment, three upper reinforcing beams 1191 are arranged at the bottom surface of the deck 111. The three upper reinforcing beams 1191 correspond respectively to three spaced vertices of the hexagonal plate. The upper reinforcing beam 1191 extends along the diagonal from the corresponding vertex to the center. The end of the upper reinforcing beam 1191, which approaches the center, is connected to an upper end of a central pontoon 119 located at the center.
[00681 Three lower reinforcing beams 1121 are arranged on the hexagonal frame.
The lower reinforcing beams 1121 respectively correspond three spaced vertices of the hexagonal frame. The lower reinforcing beam 1121 extends along the diagonal from the corresponding vertex to the center, to connect with the lower end of the central pontoon 119.
[0069] When the hexagonal plate and the hexagonal reinforcing structure are regular hexagonal structures, an angle between the upper reinforcing beams 1191 is 120. Moreover, in order to improve the overall stability, a phase difference of 60° between the upper reinforcing beam 1191 and the lower reinforcing beam 1121 adjacent to each other exists from the bottom view, thereby improving more effectively the strength of the offshore platform 11.
[00701 All of the technical features in the embodiments can be employed in arbitrary combinations. For purpose of simplifying the description, not all arbitrary combinations of the technical features in the embodiments illustrated above are described. However, as long as such combinations of the technical features are not contradictory, they should be considered as within the scope of the disclosure in the specification.
[00711 The above embodiments are merely illustrative of several implementations of the disclosure, and the description thereof is more specific and detailed, but should not be deemed as limitations to the scope of the present disclosure.
