Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power generation equipment, in particular to a sea wind and tidal current combined complementary power generation device. BACKGROUND

[0002] The ocean covers about 71% of the area of the earth's surface, and contains rich renewable energy resources. The sea wind resource is several times that of land because of the small friction on the sea surface, stable wind speed and strong wind; the tidal current energy is generated by the periodic rise and fall and flow of seawater, and has the advantages of strong predictability and large energy density.

[0003] At present, sea wind power generation and tidal current power generation are mostly independent. Wind power generation is greatly affected by weather conditions, and the power fluctuates significantly when the wind speed is unstable; tidal current power generation depends on the tides and flow of seawater, and may not be able to supply enough energy in some periods. Single energy generation cannot provide stable and continuous power output. Therefore, the wind and tidal current combined complementary power generation device can combine the sea wind energy and tidal current energy, fully utilize the advantages of the two kinds of energy, and realize the complementary utilization of energy. When the wind is weak or unstable, the tidal current power generation system can continuously and stably output power to make up for the deficiency of wind power generation; and in the period when the tidal current is weak, the wind power generation system can undertake the main power generation task to ensure that the power output of the entire power generation device remains relatively stable.

[0004] Although the existing sea wind and tidal current combined complementary power generation device can reduce the power fluctuation problem caused by single energy generation, and automatically adjust the best power generation angle through the steering mechanism according to the wind direction and tidal current direction, the existing sea wind and tidal current combined complementary power generation device usually controls the steering of each single generator set separately, needs to set multiple steering mechanisms, and the multiple steering mechanisms increase additional power consumption. In the existing floating island type wind turbine equipment technology, a gear set can be used to realize unified steering of multiple wind turbines to achieve the purpose of saving energy consumption, but this technology is difficult to realize the change of the relative arrangement mode of the wind turbine set, and the energy utilization rate of wind energy is not high.

[0005] In summary, how to solve the problem that in the existing floating island type wind turbine equipment technology, a gear set can be used to realize unified steering of multiple wind turbines to achieve the purpose of saving energy consumption, but this technology is difficult to realize the change of the relative arrangement mode of the wind turbine set, and the energy utilization rate of wind energy is not high has become a difficult problem to be solved in the field at present, so it is necessary to propose a sea wind and tidal current combined complementary power generation device. SUMMARY

[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 to it; the fourth fork rod and the third fork rod on the scissor arm close to one end of the first gear are respectively hinged to the first fork rod and the second fork rod adjacent to it 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 the wind turbine, and the other end of the rotating shaft is fixedly connected to an L-shaped rod, and the rotating shaft rotates 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 engaged with the first gear. The control system is used to control the rotation of the output shaft of the first driving member to drive the rotation of the first gear, thereby driving the relative position of the wind turbine to change.

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

[0013] A plurality of rotating rods are provided on the bottom wall of the pontoon. The bottom ends of the rotating rods all pass through the bottom wall of the pontoon and are fixedly connected to the tidal generator. The top ends of the rotating rods are coaxially fixedly connected to the third gear.

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

[0015] The technical principles of the above solution are as follows:

[0016] 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 and the first gear are engaged, so the rotation of the first driving member will drive the first gear to rotate. The first gear is fixed at 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 floating box. At the same time, the sliding block is slidingly fitted in the sliding rail on the top of the floating box, the third fork rod and the fourth fork rod hinged to the sliding block are hinged to each other, and the fourth fork rod and the third fork rod at one end of the sliding rail are hinged to the first fork rod and the second fork rod away from the first gear. When the first gear rotates, the fork rod structure connected thereto will move, thereby making the sliding block slide in the sliding rail, and finally realizing the change of the relative position of the wind driven generator.

[0017] The above scheme has the following beneficial effects:

[0018] 1、Compared with the single arrangement of the wind driven generator set in the prior art, the wind driven generator set can only be fixed at a specific position and orientation, and cannot adjust the spacing and layout in real time according to the change of wind force, resulting in mutual interference between the wind driven generators in strong wind, thereby reducing the power generation efficiency. The present application can flexibly adjust the spacing and layout between the wind driven generators according to the real-time wind force, for example, increasing the spacing to reduce mutual interference in strong wind, and reducing the spacing to improve the overall wind energy capture efficiency in weak wind, thereby improving the energy utilization rate of wind energy.

[0019] 2、The present application can realize automatic steering of the wind driven generator and the tidal current generator by setting the wind driven generator steering adjusting assembly and the tidal current generator steering adjusting assembly, so as to ensure that they are always at the best power generation angle. This automatic adjusting mechanism not only improves the power generation efficiency, but also reduces the need for manual intervention and reduces the operation and maintenance cost.

[0020] 3、The present application integrates wind power generation and tidal current power generation two energy systems to realize complementary utilization of energy. When the wind is weak or unstable, the tidal current power generation system can continuously and stably output power to make up for the deficiency of wind power generation; while the tidal current energy is weak, the wind power generation system outputs power 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 more stable and continuous power output.

[0021] Further, the wind driven generator steering adjusting assembly comprises a second driving member fixedly connected to the inner top wall of the upper chamber, and arc-shaped rods symmetrically and rotationally fitted to the inner top wall of the upper chamber.

[0022] The output shaft of the second driving member is coaxially fixedly connected with a fourth gear, the fourth gear is engaged with a fifth gear, and the fifth gear is fixedly connected to the bottom of one of the arc-shaped rods.

One of the pull rods is provided with a sliding groove, and the vertical ends of the L-shaped rods are slidably arranged in the sliding groove. The control system is used to control the rotation of the output shaft of the second driving member to drive the rotation of the arc-shaped rods, so as to change the orientation of the wind turbine.

[0024] Beneficial effects: Through the cooperation of the second driving member, the fourth gear, the fifth gear, the arc-shaped rod and the pull rod, automatic steering adjustment of the wind turbine can be realized. The sliding cooperation of the L-shaped rod in the sliding groove ensures that the wind turbine can quickly adjust the orientation according to the change of wind direction, and always be at the best wind-approaching angle, thereby improving the capture efficiency of wind energy. At the same time, the structure design simplifies the steering mechanism, reduces energy consumption and operation and maintenance costs.

[0025] Further, the tidal current generator steering adjustment assembly comprises sixth gears symmetrically and rotatably arranged on the inner bottom wall of the lower chamber, and the sixth gears are in meshing engagement with the adjacent third gears.

The top of the float box is provided with a wind direction detection assembly for identifying the wind direction.

[0026] Beneficial effects: Through the meshing transmission of the third driving member, the seventh gear and the sixth gear, automatic steering adjustment of the tidal current generator can be realized. This assembly can adjust the orientation of the tidal current generator in real time according to the change of tidal current direction, so as to ensure that it is always at the best power generation angle, thereby improving the utilization efficiency of tidal current energy. In addition, this design reduces the need for separate control of multiple steering mechanisms, thereby reducing energy consumption and complexity.

[0027] Further, the wind direction detection assembly comprises a detection box fixedly connected to the top of the float box, and a potentiometer type wind direction sensor fixedly connected to the inner bottom wall of the detection box.

The control system is used to receive the wind direction signal sent by the potentiometer type wind direction sensor, and to control the rotation of the output shaft of the second driving member based on the wind direction signal to change the orientation of the wind turbine.

[0028] Beneficial effects: Through the cooperation of the potentiometer type wind direction sensor and the wind direction vane, the change of wind direction can be detected in real time, and the signal can be transmitted to the control system.

[0032] The bottom of the rotating rod is fixedly connected with a ribbon, and the control system is used to control the camera to shoot the flow direction image of the ribbon to identify the direction of the tidal current.

[0033] Beneficial effects: through the cooperation of the camera and the ribbon, the direction of the tidal current can be monitored in real time.

[0036] Further, the outer side wall of the floating box is fixedly connected with a "(" shaped shield.

[0074] The control system comprises:

[0075] A wind direction and tide direction detection module is used for receiving the wind direction signal sent by the potentiometer type wind direction sensor 26 and processing the wind direction signal to generate wind direction information.

[0076] The wind direction and tide direction detection module is also used for receiving the flow direction image of the ribbon 31 shot by the camera 30 and performing image recognition on the flow direction image of the ribbon 31 to generate tide direction information.

[0081] The specific implementation process is as follows:

[0082] After the offshore wind and tidal combined power generation device is assembled on land, it is transported to the selected offshore power generation area using a large transport vessel. Upon arrival, the pontoon 1 is slowly lowered to the sea surface using the vessel's lifting equipment. Anchor bolts 29 are then driven into the seabed using anchor bolt installation equipment to ensure the stability of the entire power generation device in complex sea conditions.

[0083] 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 detection component begin operating in real time. The potentiometer-type wind direction sensor 26 monitors wind direction changes in real time via the wind vane shaft 27 and wind vane 28, converting the wind direction signal into an electrical signal and transmitting it to the wind and tidal current detection module of the control system. The tidal current detection module's camera 30 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 and tidal current detection module.

[0084] 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 collecting real-time power generation data of the wind turbine 10, such as power generation, wind speed, wind direction, rotation speed, and power generation data of the tidal current generator 15, such as power generation, tidal current speed, tidal current direction, and rotation speed.

[0085] For example, the orientation control module controls 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 current direction information transmitted by the wind direction and tidal current direction detection module. In this embodiment, the first driving member 12, the second driving member 17, and the third driving member 23 are first, second, and third step motors, respectively. Figure 1 Figure 3 Figure 4 For example, when the wind direction changes, the second step motor is started, and its output shaft drives the fourth gear 19 to rotate. The fourth gear 19 meshes with the fifth gear 20, so that the fifth gear 20 drives the arc-shaped rod 18 to rotate. The pull rod 21 between adjacent arc-shaped rods 18 moves accordingly, and the L-shaped rod 11 slides in the sliding groove of the pull rod 21. At the same time, the L-shaped rod 11 drives the rotating shaft 9 to rotate, thereby driving the wind turbine 10 to rotate and align with the wind direction.

[0086] For example, when the fourth gear 19 rotates clockwise, it can drive the fifth gear 20 to rotate counterclockwise, thereby driving the arc-shaped rod 18 integrally formed with the fifth gear 20 to rotate counterclockwise, and further driving the pull rod 21 to move and the L-shaped rod 11 to rotate counterclockwise.

[0087] For example, when the fourth gear 19 rotates clockwise, it can drive the fifth gear 20 to rotate counterclockwise, thereby driving the arc-shaped rod 18 integrally formed with the fifth gear 20 to rotate counterclockwise, and further driving the pull rod 21 to move and the L-shaped rod 11 to rotate counterclockwise. Figure 4 At the same time, if the wind power changes, the control system controls the first step motor output shaft to rotate. Due to the meshing 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 shearing fork movement, so that the sliding block 6 slides in the sliding rail to adjust the relative position between the wind turbines 10 and optimize the wind energy capture efficiency.

[0088] For example, when the fourth gear 19 rotates clockwise, it can drive the fifth gear 20 to rotate counterclockwise, thereby driving the arc-shaped rod 18 integrally formed with the fifth gear 20 to rotate counterclockwise, and further driving the pull rod 21 to move and the L-shaped rod 11 to rotate counterclockwise.

[0089] 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 to it 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.

[0090] by Figure 2 For example, for the tidal generator 15, when a change in the tidal direction is detected, the third stepper motor is started, 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 generator 15 turns and aligns with the tidal direction.

[0091] The power generation data model continuously collects historical and real-time power generation data and uses data analysis algorithms to build a power generation data model. The power generation data model can reflect the power generation performance of power generation equipment under different environmental conditions.

[0092] The power optimization module inputs real-time power generation data into the power generation data model, predicting wind power generation and tidal current generation for different time periods and generating predictions. Based on these predictions, the orientation control module proactively adjusts the relative position and orientation of wind turbines 10 and the orientation of tidal current generators 15 to maximize power generation.

[0093] 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 when the wind speed increases and increase the power generation capacity.

[0094] The energy storage control module monitors the battery charge status and the power generated by the wind turbine 10 and the tidal generator 15 in real time. When the power generated by the wind turbine 10 or the tidal generator 15 exceeds a preset threshold, the excess power is stored in the battery.

[0095] For example, when the wind is strong or the tidal current is large, the power generated is too high, and the energy storage control module will charge the excess power into the battery. When the generated power is insufficient, such as when the wind is weak or the tidal current is slow, the energy storage control module controls the battery to release the stored power, together with the power generation equipment to supply power to the external equipment, stabilizes the output power of the power generation device, and ensures that the external power equipment can continuously obtain stable power supply.

[0096] The present application realizes the complementary use of energy by integrating wind power generation and tidal current power generation systems. When the wind is weak or unstable, the tidal current power generation system can continuously and stably output power to make up for the deficiency of wind power generation; and in the period when the tidal current is weak, the wind power generation system outputs power to ensure that the power output of the entire power generation device remains relatively stable. This complementary power generation method effectively solves the fluctuation problem of single energy power generation and provides 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, saving energy loss.
