Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power, and particularly to an offshore wind power consumption and utilization system based on sharing and integration. Background Art

[0002] At present, traditional fossil energy is gradually facing resource shortage and environmental problems, and there is a need to transform to clean energy. As a rich renewable energy source, especially offshore wind power, with its advantages of rich resources and non-occupation of land space, has become an important direction for energy development. And hydrogen energy, as a clean and efficient secondary energy, is an important path to realize the transformation of high-energy-consuming and high-emission fields to green and low-carbon. Moreover, with the expansion of the scale of offshore wind power, on the one hand, the traditional arranged layout has limited utilization of offshore wind farms and relatively low power generation efficiency. On the other hand, the problem of large-scale "garbage power" consumption has become increasingly prominent. Especially in the deep and far sea areas, affected by factors such as the high construction difficulty and cost of ultra-high voltage direct current transmission cables and the strong volatility of offshore wind power, it is difficult for offshore wind power to be efficiently and stably connected to the onshore grid, and there is a phenomenon of abandoned wind, and new consumption channels need to be sought.

[0003] The existing invention patent with the publication number of CN117387003A discloses a green hydrogen supply system for offshore wind power hydrogen production combined with underwater high-pressure gaseous hydrogen storage, including a wind turbine generator set, a hydrogen production platform, an underwater hydrogen storage unit and a hydrogen transmission unit; the wind turbine generator set includes a wind turbine; the hydrogen production platform includes a power regulation module, a seawater desalination module, an electrolytic cell, a compression module and a floating platform; the seawater desalination module is connected to the electrolytic cell, and the seawater desalination module is used to desalinate seawater into pure water and transport it to the electrolytic cell; the electrolytic cell is used to generate hydrogen through the electrolysis of pure water, and the electrolytic cell is connected to the compression module; the underwater hydrogen storage unit is connected to the hydrogen transmission unit. Although it solves the problems of high carbon emission intensity of traditional hydrogen production methods, high volatility of direct output of offshore wind power, high cost of deep and far sea power transmission, low energy density and poor safety of traditional compressed gaseous hydrogen storage, the specific setting of the wind turbine generator set is not disclosed, and thus the utilization rate and power generation efficiency of deep and far sea wind power need to be further verified; and the existing invention patent with the publication number of CN107250533A discloses a floating body type offshore wind power generation device, which includes an elongated floating body, sails and rudders, and has a wind power generation device and a battery on the floating body, and is equipped with GPS and communication devices, and can use long-term meteorological information to judge a location with good wind conditions and safety, and move autonomously to generate wind power with high production utilization rate. However, there may be a situation where dynamic positioning fails, and wind waves and waves will also affect power generation, and the mechanical structure has poor durability, which in turn affects power generation efficiency. Summary of the Invention

[0008] The slide bar assembly includes at least two slide bar units. All the slide bar units intersect at the circular shaft in the middle and are respectively driven to operate by the driving assembly.

[0009] At least two limiting protrusions with a preset distance are respectively arranged at both ends of each arc track, so that the end of the slide bar unit runs between the two limiting protrusions.

[0010] Corresponding movable anchor points are respectively arranged at both ends of each slide bar unit, and corresponding fixed anchor points are arranged on each arc track. Two or three of the adjacent movable anchor points and fixed anchor points are connected to the corresponding offshore wind turbines in the wind turbine assembly through cables, so that a plurality of offshore wind turbines are adjusted to form a polygonal distribution according to the wind direction.

[0011] Optionally, pulleys are respectively connected to both ends of each slide bar unit, and arc-shaped grooves matching the pulleys are arranged on the outer side of each arc track, so that the pulleys roll in the corresponding arc-shaped grooves.

[0012] Optionally, the slide bar assembly includes a first slide bar and a second slide bar. First anchor points and second anchor points are respectively arranged at both ends of the first slide bar and the second slide bar, and corresponding third anchor points are arranged in the middle of each arc track. Two or three of the adjacent first anchor points, second anchor points, and third anchor points are connected to the corresponding offshore wind turbines in the wind turbine assembly through cables.

[0013] Optionally, the driving assembly includes a first driving member and a second driving member. The first driving member drives a first sliding rod to rotate through a circular shaft, and the second driving member drives a second sliding rod to rotate through a driving ring. The driving ring is embedded in the middle of the second sliding rod, and the circular shaft is arranged inside the driving ring and concentric with it.

[0014] Optionally, two first protrusions and second protrusions with a preset distance are respectively arranged at both ends of each arc track, and both ends of the first sliding rod and the second sliding rod run between the two first protrusions and second protrusions of each arc track.

[0021] Beneficial effects:

[0022] (1) In the system adopted in the present invention, by adding arc tracks, sliding rod assemblies, and driving assemblies, the traditional shared mooring technology that cannot change the single layout according to the wind direction is eliminated. Among them, the position of the anchor point is changed through the swinging form of the sliding rod assembly, thereby reducing the number of anchor points set, eliminating the need for subsequent seabed anchoring work, reducing the construction difficulty of the anchor points, correspondingly reducing the requirements for seabed environmental conditions, and using the sliding change of the driving sliding rod unit. Only by remotely controlling the driving assembly can the movement of the sliding rod unit be controlled to control the position and direction of the offshore wind turbine, and then facilitate the adjustment of the distribution form of multiple offshore wind turbines to enhance the utilization of wind energy resources in the sea area.

[0023] (2) Openings are made in both the arc track and the lower chassis. The upper and lower parts of the sliding rod are connected by multiple cylindrical spoiler rods, reducing the amount of material used. At the same time, in terms of hydrodynamic performance, the irregular blunt body structure can dissipate and disrupt the water flow, reducing structural damage. High-strength lightweight materials and multiple opening designs are adopted to significantly reduce the structural weight, reduce construction costs and difficulties, and reduce seabed water flow scouring. Preferably, high-strength synthetic fibers are selected to avoid the problem of easy corrosion in the marine environment.

[0024] (3) Integrate the hydrolysis hydrogen production device with the offshore platform for subsea natural gas extraction, and integrate the hydrogen and natural gas transportation pipelines for integrated transportation. Adopt a multi-angle and multi-faceted shared integration layout to improve production and consumption efficiency and reduce laying construction costs. Brief Description of the Drawings

If this specific posture changes, the directional indications will also change accordingly.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

[0039] Moreover, the technical solutions between various embodiments of the present invention can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0040] Refer to Figure 1-6 , a structural schematic diagram of an embodiment of a system for the consumption and utilization of offshore wind power based on shared integration is proposed by the present invention. Among them, the system includes a wind power generation subsystem 1, a hydrogen production unit 2, a natural gas extraction unit 3, a floating platform 4, a land power centralized control station 5 and a land energy storage station 6; among them, the wind power generation subsystem 1 is electrically connected to the land power centralized control station 5 and the floating platform 4 respectively. That is, the wind power generated by the wind power generation subsystem 1 first reaches the booster station 7 through the submarine cable, and after voltage boosting treatment, it is configured to the land power centralized control station 6 through the submarine cable for configuration and transmission. In addition, the surplus power generated by wind power generation can also be connected to the floating platform 4 through a unified cable to supply energy to a variety of power-consuming devices at one time, realizing energy preparation and power consumption.

[0041] Furthermore, the floating platform 4 is also connected to the hydrogen production unit 2 and the natural gas extraction unit 3. That is, the floating platform 4 supplies power to the hydrogen production unit 2 and the natural gas extraction unit 3 through cables. Among them, the hydrogen production unit includes an electrolytic cell 2 and a hydrogen pipeline. The electrolytic cell is connected to the floating platform 4. The electrolytic cell is used for electrolyzing seawater to produce hydrogen. The hydrogen pipeline is used to transmit the produced hydrogen to the onshore energy storage station 6. Preferably, the electrolytic cell is integrated with a supercapacitor buffer to reduce the number of starts and stops.

[0042] Furthermore, the natural gas extraction unit 3 includes a natural gas extraction device and a natural gas pipeline. The natural gas extraction device is connected to the floating platform 4. The natural gas extraction device is used for extracting natural gas. The natural gas pipeline is used to transmit the produced natural gas to the onshore energy storage station 6. Preferably, the hydrogen pipeline and the natural gas pipeline are placed in the same subsea umbilical cable and connected to the onshore energy storage station. It should be noted that the hydrogen pipeline and the natural gas pipeline are integrated into one, not one channel. The purpose is to enhance the transportation efficiency, reduce the complex connections and space occupation between underwater devices, and reduce the laying cost. Preferably, the hydrogen pipeline is lined with a metal-organic framework to block hydrogen penetration, reducing the permeability to 1×10 - 8 mL / (cm 2 ·day) or less, effectively reducing the leakage risk. And integrating the hydrogen production and the power supply unit for excavating subsea natural gas on one platform. The reason is that the subsea natural gas excavation devices are mainly concentrated in the subsea natural gas enrichment areas, and there are large unused areas on the platform. Then, a relatively small-area hydrolysis hydrogen production device can just fill the area. Therefore, preparing two kinds of energy on one platform makes the power supply more efficient and convenient, and the consumption is faster. At the same time, it also saves the work of arranging additional offshore platforms and reduces costs.

[0043] Furthermore, a hose is connected between the natural gas extraction device and the floating platform 4 to facilitate the release of the wellhead pressure and ensure safety. And the bottom of the floating platform 4 is made of lightweight corrosion-resistant materials and is also fixed to the seabed through cables.

[0044] Furthermore, the wind power generation subsystem 1 includes a subsea anchoring assembly and a wind turbine assembly connected to the subsea anchoring assembly. The wind turbine assembly includes a plurality of offshore wind turbines.

[0045] Specifically, as Figure 2-3 shown, the subsea anchoring assembly includes a base 14 fixedly connected to the seabed, two arc tracks 11 arranged on the base 14, a circular shaft 12, a sliding rod assembly, and a driving assembly. Among them, in this embodiment, the base 14 is fixedly connected to the seabed through an anchor hook 16. And the two arc tracks 11 are symmetrically arranged through the circular shaft 12 and the sliding rod assembly. The circular shaft 12 is located at the center of the two arc tracks 11. Preferably, the included angle of each arc track 11 is 120 - 130 degrees.

[0046] And the slide bar assembly includes at least two slide bar units, all of which intersect at the center of the circular shaft 12 and are respectively driven to operate by a driving assembly. Preferably, the arc track 11 is made of high-strength synthetic fiber to avoid corrosion during long-term use. More preferably, the arc track 11 and the lower base 14 are both perforated to reduce the amount of material used, greatly reduce the structural weight, reduce the construction cost and difficulty, reduce the scouring of the seabed current, and at the same time, at the hydrodynamic level, the irregular blunt body structure can dissipate and disrupt the water flow, reducing structural damage. According to actual needs, the anchor hook 16 can also be replaced with a suction pile to achieve the fixing effect of the seabed anchoring assembly.

[0047] Furthermore, corresponding pulleys 17 are connected to both ends of each slide bar unit, and an arc-shaped groove matching the pulley 17 is arranged on the outer side of each arc track 11, so that the pulley 17 rotates in the corresponding arc-shaped groove, thereby improving the rotation efficiency of the slide bar unit and connecting the slide bar unit and the arc track through the pulley 17; preferably, the non-sliding area of the arc track 11 is also perforated to reduce the structural weight.

[0048] Furthermore, at least two limiting protrusions with a preset distance are respectively arranged at both ends of each arc track 11, so that the end of the slide bar unit runs between the two limiting protrusions;

[0049] Furthermore, corresponding movable anchor points are respectively arranged at both ends of each slide bar unit, and corresponding fixed anchor points are arranged on each arc track 11. One or two adjacent movable anchor points and fixed anchor points are connected to the corresponding offshore wind turbines in the wind turbine assembly through cables, so that multiple offshore wind turbines can be adjusted to form a polygonal distribution according to the wind direction, and can be dynamically adjusted according to the actual sea conditions and actual wind direction conditions to realize multi-angle utilization of wind power and increase the wind power generation efficiency.

[0050] Furthermore, a WC-Co coating is plated on the contact surface between each slide bar unit and other components to reduce the wear rate of the slide bar unit.

[0051] Furthermore, the driving assembly can also be equipped with a hydraulic backup driving system, which is used to drive the corresponding slide bar units respectively to reduce the failure rate of the operation of the slide bar assembly.

[0052] Specifically, to better illustrate the structure of the present invention, the slide bar assembly is taken as an example of two slide bar units, as Figure 2In the illustrated embodiment, the subsea anchoring assembly includes a base 14 fixedly connected to the seabed, two arc tracks 11, a circular shaft 12, a first sliding rod 13, a second sliding rod 15, and a driving assembly disposed on the base 14. Among them, the two arc tracks 11 are symmetrically arranged through the circular shaft 12, the first sliding rod 13, and the second sliding rod 15. The first sliding rod 13 and the second sliding rod 15 intersect at the center of the circular shaft 12 and are respectively driven by the driving assembly.

[0053] Among them, the driving assembly includes a first driving member 133 and a second driving member 153. The first driving member 133 drives the first sliding rod 13 to rotate through the circular shaft 12. The second driving member 153 drives the second sliding rod 15 to rotate through a driving ring 154. The driving ring 154 is embedded in the middle of the second sliding rod 15, and the circular shaft 12 is arranged inside the driving ring 154 and concentrically. Thus, each driving member controls the corresponding sliding rod to rotate. Preferably, each driving member can also be driven and controlled by a remote control method, thereby improving the control efficiency.

[0054] Further, two first protrusions 111 and second protrusions 112 with a preset distance are respectively arranged at both ends of each arc track 11, so that both ends of the first sliding rod 13 and the second sliding rod 15 run between the two first protrusions 111 and second protrusions 112 of each arc track 11. Preferably, the included angle between the two first protrusions 111 and second protrusions 112 at both ends of each arc track 11 is 15 - 20 degrees, preferably 15 degrees. And the first sliding rod 13 and the second sliding rod 15 respectively include upper and lower parts and a plurality of cylindrical first spoiler rods 131 and second spoiler rods 151 connecting the corresponding upper and lower parts. The purpose is to reduce the material usage. At the same time, in terms of hydrodynamic force, the irregular blunt body structure can dissipate energy and disrupt the water flow, reducing structural damage. Preferably, the solid cylinders of the first spoiler rods 131 and the second spoiler rods 151 can be changed to porous structures, and part of the fluid can penetrate the spoiler rods.

[0055] Further, corresponding first anchor points 132 and second anchor points 152 are respectively arranged at both ends of the first sliding rod 3 and the second sliding rod 5. A corresponding third anchor point 113 is arranged in the middle of each arc track 11. Then, two or three of the adjacent first anchor points 132, second anchor points 152, and third anchor points 113 are connected to the corresponding offshore wind turbines in the wind turbine assembly through cables to connect and fix the corresponding offshore wind turbines, and multiple offshore wind turbines are formed into a polygonal distribution to cope with the change of offshore wind force. Among them, the third anchor point 113 is a fixed anchor point, and the first anchor point 132 and the second anchor point 152 are movable anchor points. Figure 4 The figure shows the schematic diagrams of the states where the wind turbines are connected to different anchor points in a quadrilateral and a hexagonal distribution.

[0056] In practical applications, the wind turbines mainly adopt two mooring forms: quadrilateral and hexagonal, asFigure 5-6 As shown, in a mooring unit, the quadrilateral mooring has four wind turbines and four mooring points, and the hexagonal mooring has six wind turbines and six mooring points, where the black ● represents the wind turbines and the blank ○ represents the anchor points.

[0057] Specifically, when Figure 5 the shown wind turbines are in a quadrilateral shape, two wind turbines near the third anchor point 113 are fixed by three anchor points, namely the first anchor point 132, the second anchor point 152, and the third anchor point 113, through cables, and the cable connected to the third anchor point 113 is double-stranded. The remaining two wind turbines are fixed by two anchor points, namely the first anchor point 132 and the second anchor point 152, through cables. When Figure 6 the shown wind turbines are in a hexagonal shape, the wind turbines are all fixed by the first anchor point 132 / the second anchor point 152 and the third anchor point 113 through cables, and the first anchor point 132 and the second anchor point 152 are fixed through cables. All use single-stranded cables and the wind turbines are fixed by connecting to two adjacent anchor points. Compared with the traditional shared mooring layout form, in an array unit, the present invention only needs to change a few wind turbines and anchor points to achieve the change of the shared mooring layout method.

[0058] Specifically, the transformation steps are as follows:

[0059] 1. Changing from a quadrilateral to a hexagon:

[0060] As Figure 2 , 4 shown, by controlling the second driving member 153 through a remote control device, the second sliding rod 5 is driven to rotate 15 degrees clockwise along the arc track 11 through the pulley 17. In the left arc track 11, the end of the second sliding rod 5 reaches the rightmost first protrusion 111 from the leftmost first protrusion 111. When the resistance reaches the preset resistance threshold of the motor, the motor rotation is locked; similarly, the first sliding rod 13 is also driven by the first driving member 133. Different from the second sliding rod 5, the motor of the first driving member 133 provides power for the first sliding rod 13 to rotate counterclockwise. In the right arc track 11, the end of the first sliding rod 13 reaches the leftmost first protrusion 111 from the rightmost first protrusion 111. After the two sliding rods are displaced, the hexagonal shared mooring form is achieved. For the wind turbines above the sea surface, only two wind turbines need to be removed, and the double-stranded cables originally tied to the wind turbines do not need to be removed at the bottom. Only need to re-tie them to the wind turbines, and thus the construction of the hexagonal mooring is completed.

[0061] 2. Changing from a hexagon to a quadrilateral:

[0062] The second driving member 153 is controlled by a remote control device to rotate, driving the second sliding rod 5 to rotate 15 degrees counterclockwise along the arc track 11 through a pulley. In the left arc track 11, the end of the second sliding rod 5 reaches the first protrusion 111 on the left from the first protrusion 111 on the right. When the resistance reaches the preset resistance threshold of the motor, the motor rotation is locked. Similarly, the first sliding rod 13 is also driven by the first driving member 133. Different from the second sliding rod 5, the first driving member 133 provides power for the first sliding rod 13 to rotate clockwise. In the right arc track 11, the first protrusion 111 on the left at the end of the first sliding rod 13 reaches the first protrusion 111 on the right. After the two sliding rods are displaced, the six-sided shared mooring form is achieved. For the wind turbines above the sea surface, only two wind turbines need to be added. The double-strand cable does not need to be removed at the bottom. Only need to divide it from double-strand to single-strand and tie it to the added wind turbines. Each wind turbine is moored by two cables, thus completing the construction of the six-sided mooring.

[0063] In the above example, only the structure of the sliding rod assembly with two sliding rod units is listed. For the sliding rod assembly with more than two sliding rod units, the same connection relationship and settings can also be adopted. And in the offshore wind power power consumption and utilization system based on shared integration in this application, the wind power generation subsystem 1, hydrogen production unit 2, natural gas extraction unit 3, and floating platform 4 can be regarded as an overall power generation and consumption unit, and multiple groups of power generation and consumption units are arranged in the nearby sea area. This setting can reduce the cost of a single wind power platform, improve the sea area utilization rate, and the efficiency of offshore hydrogen production and natural gas extraction.

[0064] In the above embodiments, those skilled in the art can adopt the existing technology for software control. The present invention is only based on the structure of the offshore wind power power consumption and utilization system based on shared integration and the mutual connection relationship.

[0065] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
