Abstract
Description
Technical Field
[0001] The present invention relates to tidal stream generation apparatuses, and more particularly to an improvement in the structure applied to tidal stream generation apparatuses. Specifically, when a tidal energy collection device drives a counterweight to reciprocate by means of a pulley set and a rope, an impact absorption assembly member installed in a housing absorbs the inertial impact when the counterweight rises, thereby reducing impact noise and improving the operational stability and durability of a buffer structure for a tidal stream generation apparatus.
Background Art
[0002] Power resources are the core energy sources that support the operations of modern civilization, industrial production, and daily civilian needs. Currently, the main power source structure in Taiwan region consists of nuclear power generation, thermal power generation, and hydroelectric power generation from rivers. However, with the increasing awareness of environmental protection and the emphasis on sustainable development, these conventional power generation methods have become more prominent with their respective undeniable drawbacks and bottlenecks, posing potential threats to the ecosystem and the safety of the human living environment.
[0003] In nuclear power generation, the accompanying nuclear waste contains highly radioactive substances and has an extremely long half-life, so it was necessary to strictly seal it for a long time to prevent environmental and health hazards. Also, when major accidents such as malfunctions in the cooling system of a nuclear power plant or a meltdown of the reactor core occur, the radiation leaks out, making recovery even more difficult. In thermal power generation, carbon dioxide, nitrogen oxides, sulfur compounds, and particulate matter emitted when fossil fuels are burned not only dramatically enhance the greenhouse effect but also deteriorate the air quality in that area and cause acid rain. In hydroelectric power generation from rivers, due to Taiwan's steep terrain, the areas suitable for the construction of large dams are limited, and there are concerns about the power generation capacity for use as a major base load power plant. Also, the dams cut off the continuity of the rivers, affecting the migration of fish and the ecosystem in the downstream area.
[0004] In terms of green energy development, wind power has limitations such as high construction costs, noise problems, and the intermittency of wind, resulting in insufficient power generation stability. Solar power faces limitations such as manufacturing costs, land occupancy, and the inability to operate only during daylight hours. In comparison, tidal power has great potential for development because it converts the continuously fluctuating kinetic energy of ocean currents into electrical energy. However, because tidal currents are inherently irregular and possess a pulsating dynamic load that fluctuates greatly depending on sea conditions, tides, seasons, and wind direction, tidal energy acquisition devices face the following difficulties in actual operation. 1. The alternating crests and troughs of the wave cause the reciprocating mechanism to be subjected to repeated forces, making it prone to fatigue-related damage and loosening. Secondly, in order to pursue energy acquisition efficiency, it is often necessary to introduce mechanical amplification and return structures such as levers, pulleys, gears, or counterweights. While this improves the flexibility of stroke and torque configuration, it increases the friction surfaces and impact points, making it easier for impact noise and instantaneous vibrations to occur at the end of the stroke. Third, the marine environment presents problems such as corrosion due to salt damage and the attachment of organisms, which leads to soaring maintenance costs for bearings, ropes, pulleys, and guide components. 4. If the recovery mechanism relies on counterweights or elastic members, then if the current provides a sudden impact or the wave height increases suddenly, the members may move excessively due to the inertial effect, the tension may increase instantaneously, the rope may be pulled, or uneven loads may be placed on the pulleys, which can easily lead to structural interference and damage. [Overview of the project] [Problems that the invention aims to solve]
[0005] Conventional tidal current power generators combine a pulley and counterweight return mechanism with a simple housing and lever energy acquisition mechanism to convert the kinetic energy of the tidal current impact into usable mechanical energy for the power generator, and achieve continuous reciprocating operation with the counterweight. The device comprises at least a housing 1, a tidal current energy collection device 2, a pulley set 3, and a power generator. Its operating principle is as follows: when the tidal current impacts the breaker plate 23 from the inlet 111, the tidal current energy collection device 2 is driven, causing a lever rotation around the support shaft 21 as its axis. The impact rod 24 is guided by the pulley set 3 to pull the rope 35, and the counterweight 36 rises vertically. The power generator receives the kinetic energy of the impact rod 24 and generates electricity. When the tidal current recedes, the counterweight 36 descends due to gravity, and the reverse traction mechanism returns to its initial state, forming a continuous reciprocating power generation cycle.
[0006] However, the above-described structure has room for improvement in actual sea conditions. The impact of the current has instantaneous peak values, and the impact rod 24, due to lever amplification, can generate high motion speeds in a short time, and is pulled at high speed by the rope 35 to raise the counterweight 36. When the counterweight 36 rises to the end of its stroke, if there is a lack of proper energy absorption and cushioning design, the counterweight 36 may cause a collision or strong contact at the end of its rise due to inertia, generating instantaneous noise and vibration, and the tension of the rope 35 may suddenly increase, potentially creating an impact load on the first fixed pulley 33, the second fixed pulley 34, and their supporting connecting rods. Such rigid impacts are directly transmitted to the bearings, supporting connecting rods, and rope connection points, causing stress concentration, deformation, or even breakage, significantly shortening the service life of the entire device. If the tensile force due to the instantaneous impact is too large and the rope breaks, the counterweight may lose control and fall further, potentially damaging the bottom of the housing.
[0007] Therefore, after careful consideration, the creators of this invention discovered that the above objective could be achieved by adopting a buffer structure for tidal power generation equipment, and thus completed this invention.
[0008] The main objective of this invention is to provide a buffer structure for a tidal power generation device that reduces the impact that may occur at the end of the upward stroke of the counterweight, as well as the noise and vibrations resulting therefrom, by having the counterweight absorb impact energy at the end of the upward stroke of the rope through the elastic buffering action of the impact-absorbing assembly member, in order to solve the above-mentioned problems.
[0009] Another object of the present invention is to provide a buffer structure for a tidal power generation device that reduces the impact load and decreases the peak tension value transmitted to the pulley set and its related components by the configuration of the impact-absorbing assembly members described above, thereby reducing the risk of wear and damage to the rope, pulley and its support components, and improving the smoothness, durability, and reliability of the overall operation of the mechanism.
[0010] Another further object of this invention is to provide a buffer structure for a tidal current power generator that, by designing a buffer at the end of the stroke, enables the device to maintain a suitable return and continuous operating state even when there are large fluctuations in sea conditions or impacts from tidal currents, reduces the frequency of maintenance, suppresses maintenance costs, and maintains the long-term stable operation and power generation efficiency of the tidal current power generator. [Means for solving the problem]
[0011] To solve the above problems, the buffer structure for a tidal power generation device of the present invention employs the following means. A buffer structure for a tidal power generation device according to one aspect of the present invention is: A housing having a first plate and a second plate, with a third plate installed on both sides of the first and second plates, an inlet provided at the bottom of the first plate, and an outlet provided at the bottom of the second plate, It has a support shaft, with rotating shaft seats installed at both ends thereof, and the plurality of rotating shaft seats are each connected to the third plate, and a wave-breaking plate and an impact rod are extended from the support shaft, and the wave-breaking plate and the impact rod are installed perpendicular to each other, and the wave-breaking plate is adjacent to the inlet and parallel to the inlet, and a tidal energy collection device The pulley set has a first connecting rod and a second connecting rod, both ends of which are connected to the third plate, respectively, and a first fixed pulley and a second fixed pulley are installed at the intermediate portions of the first and second connecting rods, respectively, the first connecting rod is interposed at the front end of the impact rod, the second connecting rod is adjacent to the top of the housing, and a rope is installed on the pulley set, a counterweight is connected to one end of the rope, and the other end of the rope is connected to the end of the impact rod, and the pulley set passes through the second fixed pulley and the first fixed pulley in sequence. It has a support plate with both ends connected to the third plate, a through hole for passing the rope through is provided in the middle portion of the support plate, and a plurality of shock-absorbing members are installed below the support plate, and a shock-absorbing assembly member surrounds the through hole, The system includes a power generation device that operates to generate electricity by receiving energy transmitted by the aforementioned impact rod. [Effects of the Invention]
[0012] This invention, through the configuration of the aforementioned shock-absorbing assembly members, reduces the impact load and decreases the peak tension value transmitted to the pulley set and its related components, thereby reducing the risk of wear and damage to the rope, pulley, and its support components, and improving the smooth operation, durability, and reliability of the entire mechanism.

Mode for Carrying Out the Invention
[0015] The present invention will be described through the following embodiments of the invention. However, the following embodiments do not limit the invention according to the utility model registration claims. Also, not all combinations of features described in the embodiments are essential for the solution means of the invention.
[0016] The buffer structure for a tidal power generation device according to the present invention mainly includes a housing 1, a tidal energy collection device 2, a pulley set 3, a power generation device 4, a control module 5, and a shock absorption assembly member 6 where the features of the present disclosure exist. Specifically, the present invention converts the instantaneous thrust formed when the tide enters the housing 1 into mechanical displacement by the pivotal lever motion of the tidal energy collection device 2. On the one hand, impact energy is output to the energy storage device 41 by the impact rod 24. On the other hand, a counterweight 36 is pulled by the rope 35 and the pulley set 3 to form a reset recovery mechanism. Here, the shock absorption assembly member 6 is arranged at the end position of the rising stroke of the counterweight 36, absorbs the inertial impact energy when the counterweight 36 rises at high speed, is used to reduce shock noise and vibration, and reduces the instantaneous peak value load received by the rope 35, the first fixed pulley 33, the second fixed pulley 34, the first connecting rod 31, and the second connecting rod 32, improving the overall durability and operating stability (see FIGS. 1, 4, and 11).
[0017] First, the basic structure of this device will be described. Housing 1 is composed of a front and rear main body made up of a first plate 11 and a second plate 12, and a third plate 13 is installed between both sides so as to surround the containment space (see Figure 5). An inlet 111 for letting seawater in is provided at the bottom of the first plate 11, and correspondingly, an outlet 121 for letting seawater out is provided at the bottom of the second plate 12. By arranging the inlet 111 and outlet 121 opposite each other, the external current enters the inside of Housing 1 from the inlet 111, forming an impact flow field, and then is discharged from the outlet 121, thus creating a flow path that can act in conjunction with each other. To control the water flow, the first plate 11 is equipped with a first gate 112 and a first power mechanism 113 at the inlet 111, and the second plate 12 is equipped with a second gate 122 and a second power mechanism 123 at the outlet 121. The first power mechanism 113 and the second power mechanism 123 receive control signals and control the opening and closing of the first gate 112 and the second gate 122 by raising / lowering or rotating. By controlling the opening and closing of gates 112 and 122, the housing 1 can be sealed to protect the internal mechanisms during maintenance, in the event of an anomaly, or in adverse sea conditions. In addition, by adjusting the amount of water flowing in and out in different wave conditions, interference from backflow can be reduced, and the wave-breaking plate 23 can be maintained under favorable stress conditions. Furthermore, multiple legs 14 are installed at the bottom of the housing 1 (see Figures 11 and 12), and a third power mechanism 141 is installed on each leg 14. The third power mechanism 141 receives control signals and drives the legs 14 to rise and fall, thereby adjusting the height of the housing 1 to match tidal changes. In other words, by adjusting the height of the housing 1, the position of the inlet 111 relative to the sea surface can be made to correspond to differences in tidal level and wave height, thereby improving the stability and predictability of kinetic energy acquisition.
[0018] The tidal energy collection device 2 is located within the housing 1 and has a support shaft 21 (see Figure 2). Both ends of the support shaft 21 are connected to the third plate 13 by a rotating shaft seat 22, respectively. The support of the rotating shaft seat 22 forms a pivot point on the support shaft 21 that allows it to pivot relative to the third plate 13, enabling the tidal energy collection device 2 to reciprocate under the thrust of the tidal current. A wave-breaking plate 23 and an impact rod 24 are extended from the support shaft 21, perpendicular to each other. The wave-breaking plate 23 is adjacent to and parallel to the inlet 111, and is designed to directly act on the stress surface of the wave-breaking plate 23 so that torque is generated after the tidal current enters from the inlet 111. A projection 25 is provided at the end of the impact rod 24 for transmitting kinetic energy to the energy storage device 41 of the power generation device 4. The projection 25 may be a bump, a column projection, or another structure capable of concentrating contact force, thereby more effectively introducing impact energy into the energy storage device 41. The lever arm of the impact rod 24 is designed to be longer than the wave-breaking plate 23, thereby amplifying the velocity of the end due to the lever principle. In this way, as the wave-breaking plate 23 is pivoted by the thrust of the current, the high velocity of the end of the impact rod 24 causes it to collide with the energy storage device 41, and a repeatable impact output is formed during the reciprocating process.
[0019] The pulley set 3 is installed inside the housing 1 and has a first connecting rod 31 and a second connecting rod 32, both of which are connected to the third plate 13. A first fixed pulley 33 and a second fixed pulley 34 are installed in the middle of the first connecting rod 31 and the second connecting rod 32, respectively (see Figures 3 and 9). The first connecting rod 31 and the second connecting rod 32 serve as load support components for the pulley, and the first fixed pulley 33 and the second fixed pulley 34 form fixed guide points inside the housing 1, creating a path for the rope 35. A counterweight 36 is connected to one end of the rope 35, and the other end passes through the second fixed pulley 34 and the first fixed pulley 33 in sequence before being connected to the end of the impact rod 24. The winding guide of the rope 35 allows the angular displacement of the impact rod 24 to be converted into the linear displacement of the counterweight 36, and the upward and downward movement of the counterweight 36 supplies a recovery tensile force to the impact rod 24. In this way, when the impact rod 24 is driven to swing backward by the current, the rope 35 pulls the counterweight 36 upward. Conversely, after the current recedes, the gravity of the counterweight 36 pulls the impact rod 24 back to its initial position via the rope 35, and the breaker plate 23 also recovers its posture to receive impact synchronously, allowing the next current impact cycle to begin. The pulley set 3 also further includes a guide tube 37 in which the guide tube 37 is connected to the housing 1 to accommodate the counterweight 36, thereby limiting the vertical displacement of the counterweight 36 within the guide tube 37 and preventing collision with other components in the housing 1. The guiding limitation of the guide tube 37 reduces deflection and oscillation when the counterweight 36 is displaced back and forth, and also reduces the situation in which the rope 35 is pulled laterally by the deflection of the counterweight 36, further improving the operational stability of the rope 35 and the fixed pulleys 33 and 34.
[0020] Next, the shock-absorbing assembly member of the present invention will be described. As shown in Figures 3 and 4 (the position of the support plate 61 is indicated by a dashed line), the shock-absorbing assembly member 6 is installed below the pulley set 3 and is located at the end of the upward path of the counterweight 36, providing energy absorption and buffering when the counterweight 36 is rapidly pulled up to the end of its stroke. More specifically, the position of the shock-absorbing assembly member 6 corresponds to the position where the counterweight 36 approaches the upper pulley loading area structural limiting area when it rises at high speed, so that it intervenes in energy absorption in advance before the counterweight 36 reaches the end of its stroke, preventing a strong impact from directly occurring on the metal loading components. The shock-absorbing assembly member 6 has a support plate 61, and both ends of the support plate 61 are firmly connected to the third plates 13 on both sides of the housing 1, forming a horizontal loading structure. The support plate 61 is firmly attached to the third plate 13 by screws, rivets, or other fastening methods, and is designed not to displace under force, and to predictably hold the compression stroke experienced by the shock absorbing members 63. Through holes 62 are provided in the middle portion of the support plate 61, corresponding to the vertical descent path of the rope 35, allowing the rope 35 to pass through and guiding the direction of travel of the stroke end of the rope 35 to reduce the risk of displacement, wear, or jumping. In specific forms, the edges of the through holes 62 are rounded or fitted with wear-resistant kits to reduce localized wear caused by contact with the edges of the holes when the tension of the rope 35 fluctuates. Furthermore, it should be noted that the support plate 61 has multiple shock absorbing members 63 on one side facing the counterweight 36, and the shock absorbing members 63 are arranged in an annular or symmetrical manner surrounding the through holes 62. By arranging them in annular or symmetrical manner, the force received by the counterweight 36 when it makes contact becomes more uniform, reducing situations such as deformation, rebound, and partial wear caused by receiving eccentric forces. In this embodiment, the shock absorbing member 63 is a helical compression spring, but it may be changed to a high-density rubber block, a hydraulic damper, or another elastic member having energy absorption properties.When the current is strong and the rope 35 is pulled by the impact rod 24 to rapidly lift the counterweight 36, the counterweight 36 approaches the top of its stroke and first contacts and abuts the impact absorbing member 63. The impact absorbing member 63 is elastically compressed and deformed, absorbing the kinetic energy of the counterweight 36. This prevents the counterweight 36 from colliding with the support plate 61 due to rigid impact, or reduces impact noise by preventing the rope 35, fixed pulleys 33 and 34, and connecting rods 31 and 32 from receiving excessive instantaneous peak loads. Over-stroke and interference due to rebound are suppressed, improving the smoothness and overlap of the reciprocating operation. Furthermore, the impact absorbing member 63 provides controllable energy-absorbing deformation at the stroke end, further slowing the increase in tension of the rope 35, reducing the impact force on the bearings of the fixed pulleys 33 and 34 and the accumulation of fatigue in the rope 35, which is effective in operation in long-term irregular sea conditions. Once the current recedes or the release of impact energy is complete, the counterweight 36 descends due to the action of gravity, and at the same time, the impact absorbing member 63 recovers from its compressed state and can provide elasticity to assist in recovery. This makes the recovery process of the counterweight 36, rope 35, and impact rod 24 smoother, improving overall circulation efficiency and structural durability.
[0021] The power generation device 4 receives energy transmitted from the impact rod 24 and converts it into electrical energy, and includes an energy storage device 41 and a generator set 42 (see Figure 12). The energy storage device 41 is connected to the first plate 11 and corresponds to the tidal energy collection device 2. When the breaking plate 23 is subjected to an impact from the tidal current, the energy storage device 41 receives the impact from the projection 25 of the impact rod 24 and converts the kinetic energy into continuous energy (e.g., atmospheric or hydrostatic pressure). The energy storage device 41 may be a pneumatic energy storage structure, a hydraulic energy storage structure, or another structure capable of instantaneously smoothing the impact, and the generator set 42 obtains driving energy in a stable form. The energy storage device 41 may be equipped with a spring 43 to assist in accelerating the return of the impact rod 24 after impact. The recovery force provided by the spring 43 can be combined with the recovery tensile force of the counterweight 36 to further accelerate the recovery of the impact rod 24 and further stabilize the circulating rhythm. The generator set 42 is operated continuously to receive the continuous energy and generate electricity.
[0022] The control module 5 is installed inside the housing 1 and includes a battery 51, a wireless receiver 52, and a water level sensor 53 (see Figure 12). The battery 51 is electrically connected to the power generator 4 and each power mechanism, storing electrical energy and supplying power. The wireless receiver 52 receives external signals. The water level sensor 53 detects the water level, generates a control signal, coordinates the opening and closing of the first and second gates, adjusts the height of the legs 14, and ensures that the device operates in optimal condition. Specifically, the control module 5 can adjust the extension and retraction of the legs 14 based on the sea level height detected by the water level sensor 53, maintaining the relative positions of the inlet 111 and the wave-breaking plate 23 within a suitable current-receiving area. Furthermore, by controlling the closing of gates 112 and 122 based on sea conditions or as required for maintenance, the internal components of the housing 1 are prevented from being subjected to unnecessary impact or erosion, thereby improving overall reliability.
[0023] The following describes the actual operation flowchart of this invention. As shown in Figures 6, 7, and 8, when the current enters the housing 1 from the inlet 111 and impacts the wave-breaking plate 23, the wave-breaking plate 23 rotates from vertical to horizontal by lever motion with the support shaft 21 as its center, and the impact rod 24 is driven to rotate from horizontal to vertical, causing the projection 25 to collide with the energy storage device 41. At the same time, the rotational stroke of the impact rod 24 pulls the rope 35, and after the rope 35 is guided by the first fixed pulley 33 and the second fixed pulley 34, the counterweight 36 inside the guide tube 37 is rapidly pulled upward. In the case of high waves, the upward speed and inertia of the counterweight 36 increase, and when the counterweight 36 rises to its end, as described above, it comes into contact with the impact-absorbing member 63 of the impact-absorbing assembly member 6, thereby absorbing the impact and eliminating noise. Furthermore, the energy absorption of the shock-absorbing member 63 can reduce irregular vibrations caused by rebound at the end of the counterweight 36, further smoothing out tension changes in the end region of the rope 35 and reducing the impact force and wear experienced by the fixed pulleys 33 and 34. After the impact of the current has ended, the counterweight 36 is rapidly displaced downward, aided by gravity and the restorative elasticity of the shock-absorbing member 63, driving the rope 35 to pull in the reverse direction to return the impact rod 24 and wave-breaking plate 23 to their initial state, in preparation for the next impact cycle.
[0024] In other preferred embodiments, the pulley set 3 may further include a third connecting rod 32A and a fourth connecting rod 32B, and a third fixed pulley 34A and a fourth fixed pulley 34B are installed, respectively (see Figures 9 and 10). The rope 35 passes through the fourth, third, second, and first fixed pulleys in sequence, and the multiple sets of pulleys alter the rope's path and torque distribution, allowing the stroke, equivalent stress, or recovery characteristics of the counterweight 36 to be adjusted as needed for the design and applied to the output requirements of different housing sizes or different sea conditions. In this embodiment, the impact-absorbing assembly member 6 is similarly installed below the pulley set (for example, below the support plate 61 or other connecting rod structures) to provide the same collision-preventing cushioning effect. In other words, regardless of whether the pulley arrangement consists of two fixed pulleys or multiple fixed pulleys, the mere presence of a rapidly rising stroke end on the counterweight 36 allows the impact at the end to be absorbed by the shock-absorbing assembly member 6, while simultaneously reducing the peak stress values of the rope 35 and the pulley load component.
