Abstract
Description
Tidal range power generation complementary system and construction method thereof Technical Field
[0001] The invention relates to a tidal power generation complementary system and a construction method thereof. Background Art
[0002] Power generation facilities that use ocean energy include tidal power generation systems that use the continuous fluctuations in the height of the sea surface to convert it into electricity, and tidal power generation systems that use the changes in tidal potential energy that occur during high and low tides to convert it into electricity.
[0003] Regarding the tidal power generation system, the potential energy does not change significantly at the extreme time points of high tide and low tide. In the continuous power generation system, these two weaknesses are formed, making it impossible to continuously output electricity at full load.
[0004] The tidal range time curve T / C formed by high and low tides is shown in Figure 1. Depending on the geographical environment, the tidal range height varies. For example, if the tidal range height H is 5 meters and a 24-hour cycle is taken, a tidal range time curve T / C is distributed according to this time. In the upper and lower amplitudes of low tide and high tide, there is a slow flow time T2 in the middle, and the interval rushing time T1 has a physical quantity with obvious potential energy change relative to the receptor of the facility. Therefore, within the rushing time T1 section, the receptor of the facility, such as the blades of a generator, will generate obvious fluid force. The part of the slow flow time T2 cannot generate obvious physical energy for the receptor, which is a weak stable section.
[0005] There are two high and low tides in a 24-hour day. In the cycle of this curve, if continuous power generation is taken, the system will lack momentum during the slow flow period T2 and cannot output at full load. In particular, at the peak or the lowest turning point of the slow flow period T2, the system will experience a brief stagnation.
[0006] The present invention provides a tidal power generation complementary system and a construction method thereof. In the portion of the slow flow period T2, another conversion device performs full power generation, so that the system is supplemented to a stable power output, solving the problem of insufficient physical energy of the fluid in the slow flow period T2.

DETAILED DESCRIPTION
[0048] The present invention provides a tidal power generation complementary system and construction method thereof for providing a tidal power generation facility for bay construction. The system executes interactive complementary power generation at the turning point of the curve in response to high / low tides and changes in water levels. The system is constructed with a storage weir pool facing the direction of tidal energy driving in and facing the grid. The storage weir pool is further divided into a left pool area and a right pool area. The left pool area and the right pool area are respectively equipped with respective energy conversion devices driven by the energy of the passing water flow to generate electricity. A control system is used to instruct the two conversion devices to exchange working timings according to the tidal state. By means of this handover operation, when one device is driving energy from the tidal wave, the other device can generate electricity to compensate for the system power, thereby significantly maintaining the stable output of the system power.
[0049] The conversion equipment assembly is provided with a kinetic energy conversion device. The converted kinetic energy is transmitted upward through a path to a generator located above the highest tide level at high tide. The path is a transmission shaft. A speed change device can be indirectly provided between the transmission shaft and the generator to achieve power generation speed modulation. This modulation facilitates the allocation of power output per unit time or adjustment in response to changes in tidal energy.
[0050] The system is equipped with a control system, which is equipped with a timing control unit to instruct the left and right pool areas to work in sequence according to the tidal range time curve. The control system is also equipped with a flow force sensing unit to obtain tidal current information and provide it to the flow control device as a reference for adjusting the operation of the kinetic energy conversion device.
[0051] The normal operation of this system is to use a timing control unit to operate two groups of conversion equipment, one on the left side and one on the right side, belonging to the left pool area and the right pool area respectively, and configure the alternating complementary power generation according to the changing state of the tidal range time curve. The generated electricity is integrated and output by a confluence unit through an electrical processing unit, and the kinetic energy conversion device is provided with a drum body, the outer periphery of which is combined with the culvert dug in the dike, and the axial interior is connected to a flow cylinder body, and the flow cylinder body provides an axial arrangement of a turboprop device. The flow cylinder body is expanded to face the ocean end and is provided with a collecting cone. The outer end of the collecting cone is provided with a gate control device, which is a gate plate or a plurality of grid plates combined.
[0052] The system provides support planes at equal angles on the surface of the pivoting body of the turboprop device. The support planes provide a blade assembly. The working angle position of the blades of the turboprop device is adjustable. One limit is that it can replace the function of the gate control device to block the flow cylinder. In addition, the angular position of the blade setting can be adjusted according to the physical state of the tide and the actual power demand.
[0053] The present invention primarily utilizes a control system to coordinate the operation of the left and right conversion devices in the operating system with respect to the tidal range time curve. When the operating energy of one device decreases, the other conversion device takes over and performs power generation. This handover and complementarity of power generation schedules maintains the stability of the system's power output. The system and its operating state of the present invention are illustrated below:
[0054] First, please refer to Figure 2. The compensation system 100 is located in a bay or any suitable seashore. A large dike 11 is installed to convert the inland section into a storage weir 10. In the center of the storage weir 10, a partition 12 is provided to separate a left pool area 10A and a right pool area 10B. The left pool area 10A and the right pool area 10B are respectively equipped with a left-mounted conversion device 20A and a right-mounted conversion device 20B. The upper side of the dike 11 can be used as a traffic road 13 and is equipped with a guardrail 14. The structure can be greened to match the natural environment or beautified as a leisure venue, further providing a scientific learning area for schoolchildren.
[0055] The left conversion device 20A and the right conversion device 20B are respectively equipped with a kinetic energy conversion device 30 and a generator 60. The kinetic energy conversion device 30 is installed in the culvert 15 at the bottom position of the dike 11 near low tide. The generated power is transmitted through a path to the generator 60 located above the highest water surface at high tide. The generator 60 can be easily maintained near the road 13 and avoid seawater erosion. A turboprop device 300 is installed on the internal shaft of the kinetic energy conversion device 30.
[0056] Referring again to FIG. 3 , the kinetic energy conversion device 30 of the compensation system 100 is configured to receive the seawater flowing into the storage weir 10 during high tide. During this process, the turboprop device 300 receives the fluid energy of the seawater flowing through and converts it into rotational kinetic energy to drive the generator 60.
[0057] Referring again to FIG. 4 , during low tide, the kinetic energy conversion device 30 of the compensation system 100 receives the fluid force from the storage weir 10 and feeds it back to the ocean. This process activates the turboprop 300, and the energy generated is transmitted to the generator 60 at a height, providing a basis for the generator 60 to generate electricity.
[0058] The above description is a combined description of the basic working principle of the kinetic energy conversion device 30 to which the left-mounted conversion device 20A or the right-mounted conversion device 20B belongs respectively. The system further needs to be controlled, and the control method is described below.
[0059] Please refer to Figure 5 (in conjunction with Figure 2) again. The mechanical rotational kinetic energy generated by the kinetic energy conversion device 30 is indirectly transmitted to the generator 60 as the basis for power generation. The left-mounted conversion device 20A and the right-mounted conversion device 20B are respectively equipped with a flow sensing unit 21 and a flow control device 22, which are controlled by a timing control unit 26 provided in the control system 20. The flow sensing unit 21 senses the physical state of the tidal current, such as flow velocity or pressure, and the obtained information is transmitted to the flow control device 22 to adjust the working state of the kinetic energy conversion device 30. The working state of the gate control device 40 is mainly adjusted according to the physical quantity of the fluid or the tidal range curve.
[0060] The electricity generated by the generator 60 is processed by the electrical processing unit 23 and then collected by the confluence unit 24 and transmitted to the supply end 28. The power at the supply end 28 is then branched and supplied to a storage unit 25 of the control system 20. The storage unit 25 provides operating power to a timing control unit 26. The timing control unit 26 also monitors the left-hand conversion device 20A and the right-hand conversion device 20B. The timing control unit 26 can be further equipped with a liquid level detection unit 27. The tidal range information detected by the liquid level detection unit 27 is directly provided to the timing control unit 26 as a basis for calculation parameters.
[0061] The control system 20 controls the timing of the operation of the left-mounted conversion device 20A and the right-mounted conversion device 20B respectively. The parameters can be manually set according to the current status of the high / low tide and used as calculation parameters for the program.
[0062] Please refer to Figure 6 (the explanation of this figure shows that the twists and turns of the tidal time curve T / C are synchronously represented by the height of the high / low tidal difference). Under the working state controlled by the control system 20, the tidal time curve T / C is a fluctuation curve of the normal high / low tide cycle. The drop of the curve is 5 meters for example. Corresponding to the time of the tidal time curve T / C, there are the box opening switch curve LG / C for the activation of the work executed by the conversion device 20A on the left, and the volume curve V / C of the storage capacity change of the conversion device 20B on the right, and the box opening switch curve RG / C belonging to the opening and closing work.
[0063] As mentioned above, the tidal difference time curve T / C forms a front and back rushing flow time T1 and a slow flow time T2 according to the time change and the entry and exit time interval. The left-placed conversion device 20A and the right-placed conversion device 20B correspond to the rushing flow time T1 and the slow flow time T2, generating the box opening and closing curves at different working time points (in order to correspond to the front and back relationship, this figure is divided into upper and lower parts by the tidal difference time curve T / C. The rushing flow time T1 and the slow flow time T2 corresponding to the left-placed conversion device 20A and the right-placed conversion device 20B and the left pool area 10A and the right pool area 10B are shown first).
[0064] When the ocean naturally rises and falls, according to the tidal range time curve T / C, there is a rushing flow period T1 with greater fluid flow energy, and a weak slow flow period T2. During the slow flow period T2, the curve reaches the critical point of rising and falling exchange, and the flow force at this point cannot occur.
[0065] The rush flow time T1 and the slow flow time T2 are alternating and continuous. The benchmark for the system operation is the box mouth switch curve LG / C of the left-set conversion device 20A, which is the box mouth switch working curve for opening the gate control device 40 belonging to the system. The right-set conversion device 20B is the box mouth switch curve RG / C for its box mouth switch.
[0066] The corresponding working states of the above two curves are that the box opening switch curve LG / C of the left conversion device 20A is in the open period, and the box opening switch curve RG / C of the right conversion device 20B is in the closed period, and the opening and closing actions of the two are continuously exchanged.
[0067] In addition, the time of exchange can be advanced or delayed with respect to each other. The adjustment of the time can adjust one of the devices ready to take over, overcome the static friction effect of the mechanism in a static state, and make the critical time point of taking over power generation to generate sufficient electricity.
[0068] The basic control element is that the box opening switch curve RG / C corresponding to the right-hand conversion device 20B of the system has an opposite working sequence for the opening and closing time points of the gate control device 40 to which it belongs, corresponding to the box opening switch curve LG / C of the left-hand conversion device 20A.
[0069] Referring to Figure 2 , the operating timing of the left-side conversion device 20A and the right-side conversion device 20B is swapped based on the corresponding changes in the current and tide flow, as described above. The kinetic energy conversion device 30 in the left pool section 10A is operated by the gate switch curve LG / C programmed by the timing control unit 26. At high tide, the kinetic energy conversion device 30 is opened during the surge period T1, allowing the current to enter the left pool section 10A. Before the left pool section 10A is filled, if the depth reaches 4.5 meters, it is set as the starting point of the slow flow period T2. At this time, during the slow flow time period T2, the kinetic energy conversion device 30 of the left pool area 10A is closed, and the left pool area 10A is full of water. At the starting point of the slow flow time period T2, the kinetic energy conversion device 30 of the right pool area 10B is opened synchronously (i.e., the corresponding box opening switch curve RG / C is opened) so that the water level during the high tide process in the slow flow time period T2 enters the right pool area 10B which is still empty. When the slow flow time period T2 reaches the end point, the left device 30 is opened again. The port of the conversion device 20A drives the kinetic energy conversion device 30 to close the fluid passage of the right conversion device 20B. At this time, the left pool area 10A has previously closed the flow path, so that the accumulated seawater level is higher than the ocean surface. As the seawater level drops, the potential energy is released through the kinetic energy conversion device 30 to generate energy conversion. As time progresses, when the second flushing process T1 is reached, the water level of the right pool area 10B, which was previously closed, is higher than the ocean surface. At the closing time of schedule T1, the box mouth of the kinetic energy conversion device 30 of the right pool area 10B is opened synchronously, and the kinetic energy conversion device 30 of the right pool area 10B is powered by the feedback of seawater to the ocean to generate electricity. When the second rushing schedule T1 of the left conversion device 20A is reached, the kinetic energy conversion device 30 of the left pool area 10A is opened, and the kinetic energy conversion device 30 of the right pool area 10B is closed synchronously, so that the rising tide current can enter the left pool area 10A through the kinetic energy conversion device 30 for the handover opening and closing exchange operation.
[0070] The above state is based on the continuous distribution of the front and rear rushing time T1 and the slow flow time T2. The kinetic energy conversion devices 30 belonging to the left conversion device 20A and the right conversion device 20B are respectively modulated by the box opening switch curve LG / C and the box opening switch curve RG / C. The timing points of switching the two kinetic energy conversion devices 30 are staggered. At different timing points, the weak energy part of the slow flow time T2 between high tide and low tide can be obtained, and the alternating work can achieve stable power generation execution, so that the system can converge a stable power output.
[0071] Referring again to FIG. 7 , the kinetic energy conversion device 30 includes a drum 31 , the outer periphery of which is connected to the culvert provided in the enclosure. A flow cylinder 36 extends through the center of the drum 31 at the front and rear. A turboprop device 300 is installed inside the flow cylinder 36 . Conical flow ports 32 are extended outwardly from the outer periphery of the two ends of the flow cylinder 36 to increase the flow rate of the fluid propelled by the turboprop device 300 . The expanded shape of the conical flow ports 32 allows for the collection of tidal vectors from multiple angles. The tidal flow passes through the turboprop device 300 , and the rotational power converted by the turboprop device 300 is redirected by a reversing device 35 and then transmitted upward via a drive shaft 50 to a generator 60 at a high potential energy position to generate electricity. The drive shaft 50 may be indirectly provided with a speed change device 51 so that the output working rotational speed can be adjusted according to the needs of the power generation device.
[0072] A gate control device 40 is provided at the end of the flow cylinder 36 facing the ocean to form an opening and closing of the box mouth. The gate control device 40 is composed of an embedded frame 41 connected to the outer end of the flow cylinder 36, and can form a tidal interception function through a gate plate 42. The gate plate 42 is driven by a drive unit 45 and controlled by the instructions of the flow control device 22. The gate plate 42 is lifted and lowered to achieve the opening and closing operation of the flow cylinder 36. Under normal weather conditions, the gate plate 42 can be fully opened. When the tidal force is large, the gate plate 42 can be half-opened to provide appropriate physical quantities of ocean current to pass through, so as to avoid generating a wave-like impact on the turboprop device 300 and maintain the stable operation of the turboprop device 300.
[0073] The generator 60 is located in a space above the highest height of the high tide liquid level (as shown in FIG2 ) and can be installed in a three-dimensional space connected by roads for easy maintenance. The speed change device 51 can also be installed close to the generator 60 .
[0074] A flow force sensing unit 21 in the control system is centrally provided at one end of the turboprop device 300 facing the ocean, so as to accurately detect the change in the physical energy of the tidal current passing through the flow cylinder 36 .
[0075] Please refer to Figures 8 and 9 again. The end of the flow cylinder 36 of the kinetic energy conversion device 30 facing the ocean may be provided with a gate control device 40. The gate control device 40 may be composed of a plurality of parallel grid plates 43, which are driven by a drive unit 45 to modulate the angular position via a drive shaft 44. The drive unit 45 is controlled by the flow control device 22 (as shown in Figure 5). The grid plates 43 are in the maximum closed state of angular modulation as shown in the top view of Figure 9. The edges of adjacent grid plates 43 are aligned. After the drive unit 45 rotates the drive shaft 44, the edges of each grid plate 43 are aligned to form a continuous screen (as shown in Figure 10). The whole is implemented at the outer end of the flow cylinder 36. The grid plates 43 are positioned inside the embedded frame 41 as shown in Figure 9, forming a planar barrier to block the ocean current from entering the flow cylinder 36.
[0076] 11 , the grid plate 43 is rotated by the drive shaft 44 , and the angular position thereof is changed to a half-open or fully-open arrangement, so that the flow cylinder 36 can function as a half-flow or full-flow ocean current.
[0077] In normal weather conditions, the grid plates 43 mainly operate in fully open and closed states. In a half-open state (as shown in FIG. 12 ), gaps are formed between adjacent grid plates 43 to form sea flow passages.
[0078] 13 and 14 , the working angle of the blades 34 of the turboprop device 300 is adjustable. First, it can be fully closed to open and close the passage of the flow cylinder 36. Second, it can be half-opened or fully opened to allow the passage of the ocean current. The blades 34 are powered by a shaft 340 to change their angles. In this embodiment, a plurality of support planes 330 are equiangularly spaced around the periphery of the pivot body 33. Each support plane 330 is passed through by each shaft 340, and each shaft 340 drives its respective blade 34.
[0079] Please refer to Figure 14 again. The outer circle of the pivot body 33 is equiangularly distributed with supporting planes 330 perpendicular to the radius line. The supporting plane 330 is movably pivoted with a root shaft 340. The interior of the root shaft 340 is a gear 341. The gear 341 can be meshed by a toothed disc 342, indirectly causing the root shaft 340 to form a radial rotation to drive the angular position of the blade 34 to flip. The posture shown in this figure is based on the result of Figure 13. The side edges of adjacent blades 34 are aligned, and the outer periphery of the blade 34 is aligned with the inner surface of the flow cylinder body 36, thereby forming the function of a screen flow cylinder body 36.
[0080] Please refer to FIG. 15 again. The blade 34 can be angularly positioned via the shaft 340 as described above. The angular position can be fully open or half open.
[0081] Please refer to FIG. 16 again. In the half-open state, the oblique gaps between the blades 34 lead to the flow cylinder 36 , allowing the ocean fluid to pass through the flow cylinder 36 .
[0082] The blades 34 are angularly adjusted by the root shaft 340, and the angular position can be adjusted in response to changes in the physical quantity of the ocean current. The implementation of the adjustment can be achieved by using the flow sensing unit 21 provided in Figure 5 to instruct the operation through the flow control device 22. The flow control device 22 in this system drives the gear plate 342 through any motor operation method to adjust the radial displacement of the meshing gear 341. Through this system, the function of the closed flow cylinder 36 can be replaced.
[0083] Please refer to Figure 17 again. In the system, the flow cylinder 36 is located at the end of the storage weir pool 10. A screen 70 is provided relative to the flow cylinder 36 to prevent fish from passing through. The storage weir pool 10 maintains a minimum water level for the seawater volume to be available for fish activities, thereby enabling the artificial breeding of marine fish.
[0084] The compensation system of the present invention is mainly constructed in the bay through dikes and partitions, and is separated into a left pool area and a right pool area. The left pool area and the right pool area are respectively provided with their own left conversion equipment and right conversion equipment. The working timing of the kinetic energy conversion devices respectively provided with the left conversion equipment and the right conversion equipment is controlled by a control system, and the subsequent time adjustment is performed to interactively work corresponding to the rushing time and slow flow time points of the tidal range time curve, so that the working timing of the kinetic energy conversion devices respectively belonging to the left pool area and the right pool area can interactively compensate for the slow flow time part of the tidal range time curve. The stable power output of this system is the main problem solved by the present invention. Compared with conventional facilities, the present invention is a brand-new concept that provides an innovative invention for stable system output power.
