Description

Technical Field

[0001] The present invention relates to the technical field of power generation equipment, and in particular to an offshore wind and tidal energy combined complementary power generation device. Background Art

[0002] The ocean covers about 71% of the Earth's surface and contains abundant renewable energy resources. Offshore wind resources have low friction on the sea surface, stable wind speed and strong wind force, which is several times that of onshore wind energy. Tidal energy is energy generated by the periodic rise and fall and flow of seawater, and has the advantages of strong predictability and high energy density.

[0003] At present, offshore wind power generation and tidal power generation are mostly operated independently. Wind power generation is greatly affected by meteorological conditions, and the power generation fluctuates significantly when the wind speed is unstable; tidal power generation depends on the tides and flow of seawater, and there may be insufficient energy supply during certain periods. Single energy generation is difficult to provide stable and continuous power output. To this end, the wind and tidal energy combined complementary power generation device can organically combine offshore wind energy and tidal energy, give full play to the advantages of the two energy sources, and realize the complementary use of energy. When the wind is weak or unstable, the tidal energy power generation system can continuously and stably output electricity to make up for the lack of wind power generation; and during periods of weak tidal energy, the wind power generation system can take on the main power generation task to ensure that the power output of the entire power generation device remains relatively stable.

[0004] Although the existing offshore wind and tidal energy combined complementary power generation device can reduce the power fluctuation problem caused by single energy power generation, and can automatically adjust to the optimal power generation angle through a steering mechanism according to the wind direction and tidal flow direction, the existing offshore wind and tidal energy combined complementary power generation device usually controls the steering of each single unit separately, and multiple steering mechanisms need to be set up. At the same time, multiple steering mechanisms will increase additional power consumption. In the existing floating island wind turbine equipment technology, multiple wind turbines can be uniformly steered through a gear set to achieve the purpose of saving energy consumption, but this technology is difficult to achieve a change in the relative arrangement of wind turbines, and the energy utilization rate of wind energy is not high.

[0005] To sum up, how to solve the problem in the existing floating island wind turbine equipment technology, multiple wind turbines can be turned in a unified manner through a gear set to achieve the purpose of saving energy, but this technology is difficult to achieve changes in the relative arrangement of wind turbines. The problem of low energy utilization rate of wind energy has become a difficult problem that needs to be urgently solved in this field. Therefore, it is necessary to propose an offshore wind and tidal energy combined complementary power generation device. Summary of the invention

[0006] To solve the above problems, the present invention provides an offshore wind and tidal energy combined complementary power generation device, which can uniformly change the arrangement and orientation of floating island wind turbine generator sets, while further saving energy consumption, and effectively improving the energy utilization rate of wind energy.

[0007] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: an offshore wind and tidal energy combined complementary power generation device, including a pontoon and a control system; a partition is fixedly connected to the inner wall of the pontoon, and the partition divides the interior of the pontoon into an upper chamber and a lower chamber.

[0008] A first fork rod is hinged on the top of the buoyancy box, a second fork rod is hinged on the top of the first fork rod, and a first gear is fixedly connected to the top of the second fork rod.

[0009] A slide rail is provided on the top of the pontoon, and a number of sliders are slidably fitted in the slide rail; a scissor arm is provided on the slider, and the scissor arm includes a third fork rod hinged to the top of the slider and a fourth fork rod hinged to the top of the third fork rod; the third fork rod and the fourth fork rod are both "S" shaped; one end of the third fork rod is hinged to the fourth fork rod adjacent thereto; the fourth fork rod and the third fork rod on the scissor arm near one end of the first gear are respectively hinged to the first fork rod adjacent thereto and the second fork rod at one end away from the first gear.

[0010] The sliders are each provided with a rotating shaft, one end of which passes through the slider, the third fork rod and the fourth fork rod and is coaxially fixedly connected to a wind turbine, and the other end of the rotating shaft is fixedly connected to an L-shaped rod, and the rotating shaft rotates in coordination with the adjacent slider, the third fork rod and the fourth fork rod.

[0011] A first driving member is fixedly connected to the top of the pontoon, and a second gear is coaxially fixedly connected to the output shaft of the first driving member. The second gear is meshed with the first gear. The control system is used to control the output shaft of the first driving member to rotate to drive the first gear to rotate, thereby driving the relative position of the wind turbine to change.

[0012] A wind turbine generator steering adjustment component is arranged in the upper chamber and is used for driving the L-shaped rod to rotate and thus change the direction of the wind turbine generator.

[0013] A plurality of rotating rods are arranged on the bottom wall of the pontoon, the bottom ends of the rotating rods all penetrate the bottom wall of the pontoon and are fixedly connected with tidal generators, and the top ends of the rotating rods are coaxially fixedly connected with the third gear.

[0014] A tidal current generator steering adjustment component for driving the third gear to rotate and thus changing the direction of the tidal current generator is arranged in the lower chamber.

[0015] The technical principles of the above scheme are as follows: The control system controls the rotation of the output shaft of the first driving member. Since the second gear is coaxially fixedly connected to the output shaft of the first driving member, and the second gear is meshed with the first gear, the rotation of the first driving member will drive the first gear to rotate. The first gear is fixed on the top of the second fork rod, the second fork rod is hinged to the first fork rod, and the first fork rod is hinged to the top of the pontoon. At the same time, the slider slides in the slide rail on the top of the pontoon, the third fork rod and the fourth fork rod hinged on the slider are hinged to each other, and the fourth fork rod and the third fork rod at one end of the slide rail are respectively hinged to the first fork rod and the second fork rod at one end away from the first gear. When the first gear rotates, it will drive the fork rod structure connected to it to move, and then make the slider slide in the slide rail, and finally realize the change of the relative position of the wind turbine.

[0016] The above scheme has the following beneficial effects: 1. Compared with the prior art, a single wind turbine generator set can only be fixed in a specific position and orientation, and cannot adjust the spacing and layout in real time according to wind changes, resulting in mutual interference between wind turbines in strong winds, reducing power generation efficiency. The present invention can flexibly adjust the spacing and layout between wind turbines according to real-time wind conditions by uniformly changing the arrangement and orientation of the floating island wind turbine generator sets. For example, in strong winds, the spacing is increased to reduce mutual interference, and in weak winds, the spacing is reduced to improve the overall wind energy capture efficiency, thereby improving the energy utilization rate of wind energy.

[0017] 2. The present invention can realize the automatic steering of wind turbines and tidal current generators by setting the steering adjustment components of wind turbines and tidal current generators, ensuring that they are always at the best power generation angle. This automatic adjustment mechanism not only improves the power generation efficiency, but also reduces the need for manual intervention and reduces the operation and maintenance costs.

[0018] 3. The present invention realizes the complementary utilization of energy by integrating two energy systems, wind power generation and tidal power generation. When the wind is weak or unstable, the tidal power generation system can continuously and stably output electricity to make up for the deficiency of wind power generation; and during the period of weak tidal energy, the wind power generation system outputs electricity to ensure that the power output of the entire power generation device remains relatively stable. This complementary power generation method effectively solves the volatility problem of single energy power generation and provides a more stable and continuous power output.

[0019] Furthermore, the wind turbine steering adjustment assembly includes a second driving member fixedly connected to the upper inner wall of the upper chamber, and an arc-shaped rod symmetrically and rotationally matched with the upper inner wall of the upper chamber.

[0020] The output shaft of the second driving member is coaxially fixedly connected with a fourth gear, the fourth gear is meshed with a fifth gear, and the fifth gear is fixedly connected to the bottom of one of the arc-shaped rods.

[0021] Pull rods are symmetrically arranged between adjacent arc rods, and both ends of the pull rods are hinged to one end of the arc rod adjacent to it. A slide groove is opened on one of the pull rods, and the vertical ends of the L-shaped rods are both in the slide groove and slide in cooperation with the slide groove. The control system is used to control the rotation of the output shaft of the second driving member to drive the arc rod to rotate, thereby changing the direction of the wind turbine.

[0022] Beneficial effects: Through the coordinated action of the second driving member, the fourth gear, the fifth gear, the arc rod and the pull rod, the automatic steering adjustment of the wind turbine can be achieved. The L-shaped rod slides in the slide slot to ensure that the wind turbine can quickly adjust its direction according to the change of wind direction and is always at the best windward angle, thereby improving the efficiency of capturing wind energy. At the same time, the structural design simplifies the steering mechanism and reduces energy consumption and operation and maintenance costs.

[0023] Furthermore, the tidal generator steering adjustment assembly includes a sixth gear that is symmetrical and rotationally matched with the bottom wall of the lower chamber, and the sixth gear is meshed with the third gear adjacent to it; a third driving member is fixedly connected to the top wall of the lower chamber, and the output shaft of the third driving member is coaxially fixedly connected with a seventh gear, and the seventh gear is meshed with the sixth gear adjacent to it. The control system is used to control the rotation of the output shaft of the third driving member to drive the rotation of the seventh gear, thereby changing the direction of the tidal generator; a wind direction detection assembly for identifying the wind direction is provided on the top of the buoy.

[0024] Beneficial effects: Through the meshing transmission of the third driving member, the seventh gear and the sixth gear, the automatic steering adjustment of the tidal current generator can be achieved. The component can adjust the orientation of the tidal current generator in real time according to the change of the tidal current direction, ensuring that it is always at the optimal power generation angle, thereby improving the utilization efficiency of tidal current energy. In addition, the design reduces the need to control multiple steering mechanisms separately, reducing energy consumption and complexity.

[0025] Furthermore, the wind direction detection component includes a detection box, the bottom of which is fixedly connected to the top of the buoyancy box, a potentiometer-type wind direction sensor is fixedly connected to the bottom wall of the detection box, an input shaft of the potentiometer-type wind direction sensor is coaxially fixedly connected to a weather vane shaft, an end of the wind vane shaft away from the potentiometer-type wind direction sensor passes through the top wall of the detection box and is fixedly connected to a wind vane, and a control system is used to receive a wind direction signal sent by the potentiometer-type wind direction sensor, and to control the rotation of the output shaft of the second drive member based on the wind direction signal to change the direction of the wind turbine.

[0026] Beneficial effect: Through the cooperation of the potentiometer-type wind direction sensor and the wind vane, the wind direction change can be detected in real time and the signal is transmitted to the control system. The control system automatically adjusts the direction of the wind turbine according to the wind direction signal to ensure that it is always in the best windward position.

[0027] Furthermore, a plurality of anchor rods are fixedly connected to the bottom of the pontoon; and a tidal direction detection component for identifying the tidal direction is provided at the bottom of the pontoon.

[0028] Beneficial effect: The anchor rod is fixed to the bottom of the pontoon, which can effectively stabilize the entire power generation device and prevent it from being deflected or overturned due to wind, waves or tidal currents.

[0029] Furthermore, the tidal current direction detection component includes a camera, which is fixedly connected to the bottom of the buoyancy box.

[0030] The bottom of the rotating rod is fixedly connected with a streamer, and the control system is used to control the camera to capture the flow image of the streamer to identify the direction of the tide.

[0031] Beneficial effects: Through the cooperation of the camera and the ribbon, the tidal current direction can be monitored in real time. The control system automatically identifies the tidal current direction and adjusts the direction of the tidal current generator according to the ribbon flow direction image taken by the camera.

[0032] Furthermore, the outer side wall of the pontoon is coated with a corrosion-resistant coating, and the corrosion-resistant coating is made of a polymer composite material.

[0033] Beneficial effects: The outer wall of the pontoon is coated with a corrosion-resistant coating made of a polymer composite material, which can effectively resist seawater corrosion and extend the service life of the device.

[0034] Furthermore, a “(”-shaped shield is circumferentially fixedly connected to the outer wall of the buoyancy chamber.

[0035] Beneficial effect: The "("-shaped shield fixedly connected to the outer wall of the buoyancy box can effectively reduce the direct impact of wind and waves on the buoyancy box and protect the internal structure of the device from damage.

[0036] Furthermore, it also includes an energy storage component for storing electric energy of the tidal generator and the wind generator. The energy storage component includes a battery, and the battery is fixedly connected to the bottom wall of the lower chamber.

[0037] Beneficial effects: By storing the electricity generated by wind turbines and tidal generators in batteries, it is possible to provide stable power output when power generation fluctuates or demand is low. This improves energy utilization efficiency, ensures the continuity and reliability of power supply, and provides support for peak load shifting and valley filling of the power grid.

[0038] Further, the control system comprises: The wind direction and tidal current direction detection module is used to receive the wind direction signal sent by the potentiometer-type wind direction sensor, and process the wind direction signal to generate wind direction information.

[0039] The wind direction and tidal current direction detection module is also used to receive the ribbon flow direction image taken by the camera, and perform image recognition on the ribbon flow direction image to generate tidal current direction information.

[0043] The energy storage control module is used to set the threshold of the total power generation of the wind turbine and the tidal generator, and monitor the battery power status and the total power generation of the wind turbine and the tidal generator in real time; when the total power generation exceeds the threshold, the excess power generation is controlled to be stored in the battery; when the total power generation is lower than the threshold, the battery is controlled to release the stored electric energy to stabilize the output power of the power generation device.

[0044] Beneficial effects: The wind direction and tide direction detection module obtains wind direction and tide direction in real time, providing data for equipment adjustment. The direction control module automatically controls the equipment based on the data to improve power generation efficiency and automation level. The power generation data model analyzes historical and real-time data to provide a basis for power generation prediction and equipment optimization. The power optimization module adjusts the equipment in advance according to the prediction, reduces power fluctuations, and improves energy stability. The energy storage control module monitors the amount of electricity and power, intelligently allocates storage, stabilizes the output power, improves energy utilization, and ensures stable power supply.

[0066] A plurality of anchor rods 29 are fixedly connected to the bottom of the buoyancy box 1 by bolts; a tidal current direction detection component for identifying the tidal current direction is provided at the bottom of the buoyancy box 1 .

[0067] The tidal current direction detection component includes a camera 30 , which is fixedly connected to the bottom of the buoyancy box 1 by bolts.

[0068] The bottom of the rotating rod 14 is fixedly connected with a streamer 31 by bolts; the control system is used to control the camera 30 to capture the flow direction image of the streamer 31 to identify the direction of the tide.

[0069] It also includes an energy storage component for storing the electric energy of the tidal generator 15 and the wind turbine 10. The energy storage component includes a battery, and the battery is fixedly connected to the bottom wall of the lower chamber by bolts.

[0070] The control system includes: The wind direction and tidal current direction detection module is used to receive the wind direction signal sent by the potentiometer-type wind direction sensor 26, and process the wind direction signal to generate wind direction information.

[0071] The wind direction and tidal current direction detection module is also used to receive the flow direction image of the ribbon 31 captured by the camera 30, and perform image recognition on the flow direction image of the ribbon 31 to generate tidal current direction information.

[0072] The direction control module is used to receive the wind direction information and tidal direction information transmitted by the wind direction and tidal direction detection module, and control the operation of the first driving member 12, the second driving member 17 and the third driving member 23 according to the wind direction information and the tidal direction information, so as to adjust the relative position and direction of the wind turbine 10 and the direction of the tidal generator 15.

[0073] The power generation data model is used to establish a power generation data model based on historical power generation data; the power generation data includes the power generation power, power generation power, wind speed, wind direction and rotation speed of the wind turbine 10 and the power generation power, tidal speed, tidal direction and rotation speed of the tidal generator 15.

[0074] The power optimization module is used to input real-time power generation data into the power generation data model to generate wind power generation and tidal power generation prediction data for different time periods, and at the same time adjust the relative position and orientation of the wind turbine 10 and the orientation of the tidal generator 15 in advance according to the wind power generation and tidal power generation prediction data for different time periods.

[0075] The energy storage control module is used to set a threshold value for the total power generated by the wind turbine 10 and the tidal generator 15, and monitor the battery power status and the total power generated by the wind turbine 10 and the tidal generator 15 in real time; when the total power generated exceeds the threshold value, the excess power generated is controlled to be stored in the battery; when the total power generated is lower than the threshold value, the battery is controlled to release the stored electric energy to stabilize the output power of the power generation device.

[0076] The specific implementation process is as follows: After the offshore wind and tidal energy combined complementary power generation device is assembled on land, it is transported to the selected offshore power generation area by a large transport ship. After arriving at the destination, the floating box 1 is slowly lowered to the sea surface by the lifting equipment on the ship. Subsequently, the anchor rod 29 is driven into the seabed by the anchor rod installation equipment to ensure the stability of the entire power generation device in complex sea conditions.

[0077] by Figure 1 and Figure 5 For example, after the power generation device is put into operation, the wind direction detection component and the tidal current direction detection component start to work in real time. The potentiometer wind direction sensor 26 monitors the wind direction change in real time through the wind vane shaft 27 and the wind vane 28, and converts the wind direction signal into an electrical signal and transmits it to the wind direction and tidal current direction detection module of the control system. The camera 30 of the tidal current direction detection component continuously captures the flow direction image of the streamer 31 at the bottom of the rotating rod 14, and transmits the flow direction image to the wind direction and tidal current direction detection module.

[0078] The wind direction and tidal current direction detection module processes the received signals and images to generate wind direction information and tidal current direction information. At the same time, the power generation data model starts to collect the power generation, wind speed, wind direction, rotation speed of the wind turbine 10 and the power generation, tidal current speed, tidal current direction and rotation speed of the tidal current generator 15 in real time.

[0079] by Figure 1 , Figure 3 and Figure 4 For example, the direction control module controls the operation of the first drive member 12, the second drive member 17 and the third drive member 23 according to the wind direction information and the tide direction information transmitted by the wind direction and tide direction detection module. In this embodiment, the first drive member 12, the second drive member 17 and the third drive member 23 are the first stepper motor, the second stepper motor and the third stepper motor respectively.

[0080] When the wind direction changes, the second stepper motor starts, and its output shaft drives the fourth gear 19 to rotate, and the fourth gear 19 meshes with the fifth gear 20, so that the fifth gear 20 drives the arc rod 18 to rotate. The pull rod 21 between adjacent arc rods 18 moves accordingly, and the L-shaped rod 11 slides in the slide groove of the pull rod 21. At the same time, the L-shaped rod 11 drives the rotating shaft 9 and then drives the shaft of the wind turbine 10 to rotate, thereby driving the wind turbine 10 to turn so that it is always aligned with the wind direction.

[0081] by Figure 4 For example, when the fourth gear 19 rotates clockwise, it can drive the fifth gear 20 to rotate counterclockwise, thereby driving the arc rod 18 integrally formed therewith to rotate counterclockwise, and then driving the pull rod 21 to move and thereby driving the L-shaped rod 11 to rotate counterclockwise.

[0082] At the same time, if the wind force changes, the control system controls the output shaft of the first stepper motor to rotate. Due to the engagement of the second gear 13 and the first gear 5, the first fork rod 3 and the second fork rod 4 as well as the third fork rod 7 and the fourth fork rod 8 can be driven to perform a scissors motion, so that the slider 6 slides in the slide rail, adjusts the relative position between the wind turbines 10, and optimizes the wind energy capture efficiency.

[0083] by Figure 1 For example, in strong winds, the output shaft of the first stepper motor is adjusted to rotate clockwise, driving the second gear 13 to rotate clockwise, and then driving the first gear 5 to rotate counterclockwise, thereby driving the second fork rod 4 integrally formed with the first gear 5 to rotate counterclockwise on the pontoon 1, so that the second fork rod 4 pushes the third fork rod 7 hinged thereto to move to the right, and then drives the slider 6 to slide to the right in the slide rail, so that the distance between adjacent wind turbines 10 becomes larger, reducing the mutual interference between the wind turbines 10; conversely, in weak winds, the output shaft of the first stepper motor is adjusted to rotate counterclockwise, so that all sliders 6 slide to the left in the slide rail, so that the distance between adjacent wind turbines 10 becomes smaller, thereby improving the overall wind energy capture efficiency, thereby improving the energy utilization rate of wind energy.

[0084] by Figure 2 For example, for the tidal current generator 15, when a change in the tidal current direction is detected, the third stepper motor starts, and its output shaft drives the seventh gear 24 to rotate, and the seventh gear 24 engages with the sixth gear 22, thereby driving the third gear 16 to rotate, so that the tidal current generator 15 turns and aligns with the tidal current direction.

[0085] The power generation data model continuously collects historical power generation data and real-time power generation data, and uses data analysis algorithms to establish a power generation data model. The power generation data model can reflect the power generation performance of power generation equipment under different environmental conditions.

[0086] The power optimization module inputs the real-time power generation data into the power generation data model, predicts the wind power generation and tidal power generation in different time periods, and generates prediction results. According to the prediction results, the orientation control module adjusts the relative position and orientation of the wind turbine 10 and the orientation of the tidal generator 15 in advance to maximize the power generation.

[0087] For example, when it is predicted that the wind speed will increase and the wind direction will change in the future, the control system controls the output shafts of the first stepper motor and the second stepper motor to rotate in advance to adjust the position and orientation of the wind turbine 10 in advance so that it can better capture wind energy and increase power generation when the wind speed increases.

[0088] The energy storage control module monitors the battery power status and the power generation of the wind turbine 10 and the tidal current generator 15 in real time. When the power generation of the wind turbine 10 or the tidal current generator 15 exceeds a preset threshold, the excess power generation is controlled to be stored in the battery.

[0089] For example, when the wind is strong or the tide is large, the power generation is too high, and the energy storage control module charges the excess power into the battery. When the power generation is insufficient, such as when the wind is weak or the tide is slow, the energy storage control module controls the battery to release the stored power, and together with the power generation equipment, it supplies power to external equipment, stabilizes the output power of the power generation device, and ensures that external electrical equipment can continue to obtain a stable power supply.

[0090] The present invention realizes the complementary utilization of energy by integrating two energy systems, wind power generation and tidal power generation. When the wind is weak or unstable, the tidal power generation system can continuously and stably output electricity to make up for the deficiency of wind power generation; and during the period when the tidal energy is weak, the wind power generation system outputs electricity to ensure that the power output of the entire power generation device remains relatively stable. This complementary power generation method effectively solves the volatility problem of single energy power generation and provides a more stable and continuous power output. At the same time, by uniformly changing the arrangement and orientation of the wind turbines 10, the spacing and layout between the wind turbines 10 can be flexibly adjusted according to the real-time wind conditions to save energy loss.

[0091] Embodiment 2:

[0092] As attached Figure 1 As shown, the difference from Example 1 is that the outer wall of the pontoon 1 is coated with a corrosion-resistant coating, and the corrosion-resistant coating is made of a polymer composite material. In this embodiment, the polymer composite material is an epoxy resin-based composite material.

[0093] The specific implementation process is as follows: Epoxy resin has excellent chemical stability and can effectively resist the erosion of seawater. It also has good bonding strength with reinforcing materials such as glass fiber and carbon fiber. The composite material formed has high mechanical strength and can withstand complex environmental stresses at sea. It also has good weather resistance and can maintain stable performance under conditions of long-term illumination, temperature changes, etc., to ensure the long-term use of power generation equipment.

[0094] Embodiment 3:

[0095] As attached Figure 1 As shown, the difference from Example 2 is that a “(”-shaped shield is fixedly connected to the outer wall of the buoyancy box 1 in the circumferential direction by bolts.

[0096] The specific implementation process is as follows: The “(”-shaped shield on the outer side wall of the pontoon 1 can effectively reduce the direct impact of wind and waves on the pontoon 1 and protect the internal structure of the device from damage.

[0097] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
