Description

Technical Field

[0001] The present invention relates to the technical field of tidal power generation, and particularly to a cliff-edge tidal impact power generation device and method. Background Art

[0002] Ocean energy is regarded as an important supplement due to its huge reserves and strong predictability. Existing tidal power generation technologies rely on specific geographical conditions and face problems such as ecological damage and high costs. There is an urgent need for more flexible and environmentally friendly technologies. Coastal cliff areas usually have large tidal differences and concentrated wave energy, and the natural terrain can amplify tidal impact forces. If such terrain can be efficiently utilized, the applicable scenarios of tidal energy can be expanded, especially suitable for countries with many cliffs along the coast. The progress of materials science and energy conversion technologies has made it possible to develop new tidal energy devices. The most common existing cliff-edge tidal power generation equipment is the oscillating water column device, which is a device used for impact power generation in daily life and has been widely used in the field of environmental protection energy.

[0003] When the existing oscillating water column device is in use, the water column in the power generation device moves up and down reciprocally under the action of waves. The function of the water column is similar to that of a piston. The continuous movement of the water column causes the air column above the free surface of the water column to generate oscillating motion. The air flows through a reciprocating turbine at the air outlet above the air chamber, thereby converting the kinetic energy of high-speed air into electrical energy. The biggest difference between the oscillating water column type wave energy device and other wave energy devices is that it has an air chamber. The so-called air chamber refers to a structure with an opening at the lower part immersed in seawater, enabling seawater to freely enter the air chamber. It is found in the use of the oscillating water column device that its power generation level is limited by energy conversion and cannot be effectively converted when the tidal fluctuation is small, resulting in low working efficiency of the device.

[0022] Further, it further includes a fixing ear, and one end of the fixing ear is connected to one end of the mounting box.

[0023] On the other hand, the present invention also provides a method for generating electricity by cliffside tidal impact, including:

[0024] Step S1, a groove is made at a preset position of the cliff wall, and the installation box is placed on the edge of the cliff by means of inlaying, so that the impact surface of the impact assembly faces outward to be impacted by the tide. In this process, under the action of the tidal impact, the clamping mechanism cooperates with the retraction and extension of the impact assembly, and its arc surface is retracted and expanded, so as to increase the force-bearing area for different degrees of tides;

[0025] Step S2, driving the device through the driving assembly to raise and lower the adjusting device, so as to fine-tune the height of the impact plate to better fit the impact of tides at different heights, so as to adapt to the changes in the flood season and the dry season;

[0026] Step S3, driven by the impact component, the rack of the driving component moves up and down and slides, and drives the generator meshed with it through the gears to generate electricity during sliding, and stores energy through the battery. The rectifier converts energy in this process and cooperates with the transmission box to transmit energy.

[0027] Compared with the prior art, the beneficial effect of the present invention is that the present invention converts electrical energy into direct current suitable for storage through a rectifier, and stores and manages it through a transmission box and a storage battery, thereby improving energy utilization efficiency. The existence of the adjustment device enables the rotation (or position) of the impact assembly to be precisely controlled, which can adjust the angle or posture of the impact assembly according to different tidal conditions to optimize its effect of receiving tidal impact, thereby maximizing energy capture. The drive assembly provides a power source for the adjustment device, realizes an automated and precise adjustment process, and does not require manual intervention, thereby improving the convenience and accuracy of the adjustment. The installation box provides a protective shell and installation base for the core components inside. The clamping mechanism can firmly fix and position the impact assembly, ensure that it works stably when subjected to tidal impact, prevent accidental detachment or displacement, and improve the overall safety and reliability of the device. The device is designed for use in a cliff environment and can effectively utilize the specific tidal flow conditions of the cliff. Through the cooperation of the adjustment and clamping mechanisms, the device can adapt to tidal impacts of different intensities and maintain stable operation.

[0028] In particular, the adjustment device realizes multi-dimensional and all-round adjustment of the impact assembly through the threaded connection of the first bolt, the rotational connection between the arc rod and the support rod, and the sliding connection of the support rod in the long groove of the arc rod. This design overcomes the problems of limited adjustment dimensions and insufficient adjustment accuracy of traditional devices, allowing the device to better adapt to the complex cliff tidal environment. The rotational connection between the arc rod and the support rod provides coarse adjustment capability, while the sliding connection of the support rod in the long groove provides fine adjustment capability. This combination of coarse adjustment and fine adjustment greatly improves the accuracy of adjustment, ensuring that the impact assembly can be accurately positioned in the optimal position to maximize the capture of tidal energy.

[0029] In particular, by introducing the lifting plate, the adjustment device can achieve height adjustment of the impact assembly. This enables the device to adapt to changes in different tidal water levels, ensuring that the impact assembly is always at the optimal working depth, thereby improving the energy capture efficiency. The sliding connection between the guide rail and the adjusting rod, combined with the rotation of the support rod, provides the device with more precise position control capabilities. The sliding of the adjusting rod can finely adjust the position of the impact assembly, while the rotation of the support rod can provide a large range of adjustment. This combination achieves a smooth transition from coarse adjustment to fine adjustment, improving the accuracy and flexibility of the adjustment. The connecting rod hinges the support rod and the adjusting rod together, forming a stable motion transmission mechanism. This design ensures that the rotation of the support rod and the sliding of the adjusting rod can be transmitted to the lifting plate in a coordinated manner, avoiding instability and deviation during the movement process.

[0030] In particular, by rotating the lead screw, the rotational motion can be precisely converted into the linear lifting motion of the lifting plate. This can achieve more precise and continuous height or position adjustment compared to the previous sliding or rotational adjustment methods, meeting the higher precision requirements for the working position of the impact assembly. Through the articulated locking mechanism composed of the pull rod and the positioning rod, the adjusting rod can be effectively locked in a specific position. This locking mechanism ensures that during the operation of the tidal impact power generation device, the adjusting rod will not be accidentally displaced due to vibration, water flow impact or other external forces, thus maintaining the stable working state of the impact assembly. The combination of precise lead screw adjustment and reliable position locking enables the adjustment device to more flexibly and precisely adapt to position adjustments under different tidal conditions, water flow intensities or maintenance requirements, improving the adaptability and operating efficiency of the entire power generation device.

[0031] In particular, through the structural design of the impact plate, the tripod and the connecting shaft, the impact assembly can effectively capture the impact force of the tidal water flow and convert it into rotational mechanical energy. The introduction of the screw enables the force application point and the rotation radius of the impact bracket to be adjusted, so as to adapt to tidal water flows in different directions and intensities, improving the adaptability and energy capture efficiency of the device. The impact bracket is hinged to the tripod through the connecting shaft, and the tripod is rotatably connected to the impact plate. This structural design not only ensures the rotational freedom of the impact bracket but also ensures the stability of the entire impact assembly. The impact assembly can be used in conjunction with the adjustment device described above to precisely control the position and attitude of the impact assembly through the adjustment device, further optimizing the energy capture effect.

[0032] In particular, through the mechanical clamping and releasing mechanism of the clamp, rapid clamping of the impact plate can be achieved, improving the installation and adjustment efficiency. The design of the auxiliary rod and auxiliary shaft, especially the meshing with the toothed rack, enables the opening and closing of the clamping mechanism to be controlled through remote operation, facilitating clamping in environments where direct operation is difficult. The pre-tightening force of the disc spring ensures that the clamp can reliably clamp the impact plate in the closed state, preventing loosening or falling off during operation. The clamping mechanism can be applied to impact plates of different sizes and shapes, with strong adaptability.

[0033] In particular, the fixed ear, as part of the installation box, increases the overall structural strength of the device, enabling it to withstand greater external forces and improving the reliability of the device. The fixed ear provides additional support points for the device, enhancing the anti-overturning ability and stability of the device, especially when subjected to large impact forces or when the device itself has a large weight, this effect is more obvious.

[0045] Please refer to Figure 1 and Figure 3 As shown, the present invention provides a cliffside tidal impact power generation device, including:

[0046] An installation box 1, which has a working cavity inside for installing an adjustment device and a driving device;

[0047] A power generation device, which is arranged on the installation box 1 and includes a storage battery 203, a rectifier 204, a transmission electric box 205, an impact assembly, an adjustment device, a driving assembly, a clamping mechanism, and an energy conversion device. Among them,

[0048] The storage battery 203 is used to store electric energy and is connected to one end of the rectifier 204;

[0049] The rectifier 204 is used to convert alternating current into direct current and is connected to one end of the transmission electric box 205;

[0050] The adjustment device is connected to the top end of the installation box 1 and is used to control and adjust the rotation of the impact assembly, and it is provided with a first mounting seat;

[0051] The driving assembly is connected to the top end of the adjustment device and is used to provide power for the adjustment device;

[0052] The impact assembly is used to convert tidal energy into mechanical energy, and the connection end of the impact assembly passes through the first mounting seat and is rotatably connected to the adjustment device;

[0053] The energy conversion device is meshed with one end of the impact assembly and is used to convert the mechanical energy into electric energy;

[0054] The clamping mechanism is installed on the impact assembly and is used to fix and position the impact assembly.

[0055] Specifically, the installation box 1 is made of sturdy and durable materials, such as reinforced concrete or high-strength plastics, to withstand the harsh seaside environment, including strong winds, ocean waves, and salt spray corrosion. The shape and size of the installation box 1 are designed according to the specific installation location and the scale of the device. Inside the installation box 1, there is a working chamber for installing the regulating device and the driving device. Waterproof and moisture-proof measures, as well as ventilation openings, may need to be set inside the working chamber to ensure the normal operation of internal components. The storage battery 203 is used to store electrical energy, usually a rechargeable battery such as a lead-acid battery 203 or a lithium battery. Its capacity is selected according to the rated power of the power generation device and the usage requirements. One end of the storage battery 203 is connected to the rectifier 204. The rectifier 204 is used to convert the alternating current generated by the generator 602 into direct current for storage in the storage battery 203. The specifications of the rectifier 204 are selected according to the output power and voltage of the generator 602. One end of the rectifier 204 is connected to the storage battery 203, and the other end is connected to the power transmission box 205. The power transmission box 205 is used to manage and distribute electrical energy and may include components such as circuit breakers, switches, and indicator lights. One end of the power transmission box 205 is connected to the rectifier 204, and the other end is connected to external electrical equipment or the power grid.

[0056] Specifically, the rectifier converts electrical energy into direct current suitable for storage, and the power is stored and managed through the power transmission box and the storage battery, improving energy utilization efficiency. The presence of the regulating device enables the rotation (or position) of the impact component to be precisely controlled, which can adjust the angle or attitude of the impact component according to different tidal conditions to optimize its effect of receiving tidal impacts, thereby maximizing energy capture. The driving component provides a power source for the regulating device, realizing an automated and precise adjustment process without manual intervention, improving the convenience and accuracy of the adjustment. The installation box provides a protective shell and an installation foundation for the core components inside. The clamping mechanism can firmly fix and position the impact component, ensuring its stable operation when subjected to tidal impacts, preventing accidental detachment or displacement, and improving the overall safety and reliability of the device. The device is designed for the cliffside environment and can effectively utilize the specific tidal flow conditions at the cliffside. Through the coordination of the regulating and clamping mechanisms, the device can adapt to tidal impacts of different intensities and maintain stable operation.

[0057] Specifically, as Figure 4As shown, the adjusting device includes a first bolt 302, an arc-shaped rod 303 and a support rod 304. A first screw hole 314 is provided through the mounting plate 301 and the working chamber 201. The first bolt 302 passes through the first screw hole 314 and is threadedly connected to the mounting plate 301 and the mounting box; a second mounting seat 315 is provided on the mounting plate 301. The arc-shaped rod 303 passes through the second mounting seat 315 and is rotatably connected to the mounting plate 301; a third mounting seat 316 is provided in the working chamber. The support rod 304 passes through the third mounting seat 316 and is rotatably connected to the mounting box 1; a through slot 317 is provided on the arc-shaped rod 303, and the support rod 304 passes through the through slot 317 and is slidably connected to the arc-shaped rod 303.

[0058] Specifically, the mounting plate 301 is threadedly connected to the mounting box 1 through the first bolt 302, which is the basis of the entire adjusting device and ensures the preliminary fixation of the mounting plate 301. By passing the arc-shaped rod 303 through the second mounting seat 315 on the mounting plate 301 and making a rotational connection, the operator can rotate the arc-shaped rod 303, thereby driving the components connected thereto to make a preliminary position adjustment within a large range. This rotation can change the approximate angle and direction of the impact assembly. Similarly, the support rod 304 passes through the third mounting seat 316 in the working chamber and is rotatably connected to the mounting box 1. The operator can rotate the support rod 304 to further adjust the position of the impact assembly. This rotation provides another dimension of adjustment, enabling the impact assembly to swing around the mounting box 1 to a certain extent. A through slot 317 is provided on the arc-shaped rod 303, and the support rod 304 passes through this through slot 317 and is slidably connected to the arc-shaped rod 303. By manual adjustment or power drive, the support rod 304 can be made to slide within the through slot 317, thereby achieving fine adjustment of the position of the impact assembly. This linear sliding can compensate for the deficiencies of rotational adjustment, enabling the impact assembly to be accurately positioned at the optimal position.

[0059] Specifically, the adjusting device realizes multi-dimensional and all-round adjustment of the impact assembly through the threaded connection of the first bolt, the rotational connection of the arc-shaped rod and the support rod, and the sliding connection of the support rod within the through slot of the arc-shaped rod. This design overcomes the problems of limited adjustment dimensions and insufficient adjustment accuracy of traditional devices, enabling the device to better adapt to the complex cliff-edge tidal environment. The rotational connection of the arc-shaped rod and the support rod provides the ability for coarse adjustment, while the sliding connection of the support rod within the through slot provides the ability for fine adjustment. This combination of coarse adjustment and fine adjustment greatly improves the adjustment accuracy, ensuring that the impact assembly can be accurately positioned at the optimal position, thereby maximizing the capture of tidal energy.

[0060] Specifically, the adjusting device further includes a lifting plate 306, a guide rail, an adjusting rod 309, and a connecting rod 305. The lifting plate 306 is hinged to the arc-shaped rod 303 and is connected to the mounting box 1 through the support rod 304. A chute 318 is provided on the adjusting rod 309, and the guide rails respectively pass through the chute 318 and are slidably connected to the adjusting rod 309. Fourth mounting seats 319 are provided on both the adjusting rod 309 and the support rod 304, and the connecting rod 305 passes through the fourth mounting seats 319 and is hinged to the support rod 304 and the adjusting rod 309.

[0061] Specifically, the lifting plate 306 is connected to the arc-shaped rod 303 through a hinge point and is connected to the mounting box 1 through the support rod 304. The sliding groove 318 on the adjusting rod 309 allows the guide rail to pass through to achieve sliding. The connecting rod 305 hinges the support rod 304 and the adjusting rod 309 together. Usually, such adjustment requires external drive. The drive may act on the support rod 304 to cause it to rotate around the rotational connection point (the third mounting seat 316) with the mounting box 1. Or it may act on the adjusting rod 309 to cause it to slide along the guide rail. If the support rod 304 is driven to rotate: when the support rod 304 rotates, it will try to change the position of the lifting plate 306 through its connection point with the lifting plate 306 (the connection between the support rod 304 and the mounting box 1, and the relative positional relationship between the support rod 304 and the lifting plate 306. Here, a more specific structural description may be needed, but it can be understood that the movement of the support rod 304 will affect the lifting plate 306) and the sliding connection (the long groove 317) between the support rod 304 and the arc-shaped rod 303. At the same time, the fourth mounting seat 319 on the support rod 304 will move relative to the connecting rod 305. To cooperate with the rotation of the support rod 304 or limit its movement range, the adjusting rod 309 will slide along the guide rail. The guide rail provides a sliding track to ensure the movement direction of the adjusting rod 309. The sliding of the adjusting rod 309 will transmit force or displacement to the connecting rod 305 through the hinge point between the fourth mounting seat 319 on it and the connecting rod 305. The connecting rod 305, as a connecting rod, connects the support rod 304 and the adjusting rod 309. Its function is to transmit the rotational movement (or the attempted rotation) of the support rod 304 to the adjusting rod 309 to cause it to slide. Conversely, it transmits the sliding movement of the adjusting rod 309 to the support rod 304, which may limit or assist its rotation. More importantly, the connecting rod 305 indirectly affects the position of the lifting plate 306 by restricting the relative movement between the support rod 304 and the adjusting rod 309. When the support rod 304 rotates, the connecting rod 305 will pull or push the adjusting rod 309 to slide along the guide rail, and this linkage process jointly determines the final position of the lifting plate 306. Under the coordinated action of the rotation of the support rod 304, the sliding of the adjusting rod 309, and the connecting rod 305, the lifting plate 306 will rotate around its hinge point with the arc-shaped rod 303 and may be accompanied by up and down movement (specifically depending on the connection method between the lifting plate 306 and the support rod 304). This lifting movement directly or indirectly adjusts the height or wave-facing angle of the impact component (assuming it is installed on the lifting plate 306 or driven by the lifting plate 306). By controlling the drive input (such as the angle of rotating the support rod 304 or the distance of moving the adjusting rod 309), the lifting plate 306 (and the impact component) can be precisely adjusted to the required working height or position to adapt to different tidal water levels or impact forces.

[0062] Specifically, through the introduction of the lifting plate, the adjustment device can achieve height adjustment of the impact assembly. This enables the device to adapt to changes in water levels at different tides, ensuring that the impact assembly is always at the optimal working depth, thereby improving energy capture efficiency. The sliding connection of the guide rail and the adjustment rod, combined with the rotation of the support rod, provides the device with a more refined position control capability. The sliding of the adjustment rod can fine-tune the position of the impact assembly, while the rotation of the support rod can provide a larger range of adjustment. This combination achieves a smooth transition from coarse adjustment to fine adjustment, improving the accuracy and flexibility of adjustment. The connecting rod hinges the support rod and the adjustment rod together to form a stable motion transmission mechanism. This design ensures that the rotation of the support rod and the sliding of the adjustment rod can be transmitted to the lifting plate in a coordinated manner, avoiding instability and deviation during movement.

[0063] Specifically, the adjusting device also includes a screw rod 313, a positioning block 312, a pull rod 310 and a positioning rod 311. The connecting end of the screw rod 313 is rotatably connected to the top end of the lifting plate 306 to adjust the position of the lifting plate 306; a second screw hole 320 is provided on the positioning block 312, and the screw rod 313 passes through the second screw hole 320 and is threadedly connected to the positioning block 312. A fifth mounting seat 321 is provided on the adjusting rod 309 and the positioning block 312, and the pull rod 310 and the positioning rod 311 respectively pass through the fifth mounting seat 321 and are rotatably connected to the adjusting rod 309 and the positioning block 312; the other connecting end of the pull rod 310 is rotatably connected to the connecting end of the positioning rod 311 to fix the position of the adjusting rod 309.

[0064] Specifically, when it is necessary to adjust the height or position of the impact component, the driving lead screw 313 rotates (clockwise or counterclockwise). Since the lead screw 313 is threadedly connected to the positioning block 312, the rotation of the lead screw 313 will drive the positioning block 312 to move along the axis direction of the lead screw 313 (forward or backward). The positioning block 312 is connected to the adjusting rod 309 through the pull rod 310 and the positioning rod 311. The movement of the positioning block 312 will indirectly affect the position of the adjusting rod 309 through this connection mechanism (the specific influence depends on the geometric relationship of the mechanism). At the same time, the other end of the lead screw 313 is rotatably connected to the top of the lifting plate 306. The rotational movement of the lead screw 313 will directly drive the lifting plate 306 to move up and down. By controlling the rotation angle and direction of the lead screw 313, the lifting plate 306 (and the impact component connected thereto) can be accurately adjusted to the required working height. When the lifting plate 306 and the impact component are adjusted to the ideal position, it is necessary to fix the adjusting rod 309 to keep the position stable. Operate the connection point of the pull rod 310 and the positioning rod 311 (or by controlling the relevant driving mechanism) to make the pull rod 310 and the positioning rod 311 in a specific angular position. At this time, the pull rod 310 will pull (or push) the positioning block 312, while the positioning rod 311 will limit the rotation or movement of the adjusting rod 309. Since the positioning block 312 is threadedly connected to the adjusting rod 309, the fixing of the positioning block 312 will prevent the accidental rotation of the adjusting rod 309. The triangle (or other stable structure) formed by the pull rod 310 and the positioning rod 311 locks the adjusting rod 309 in the current position to prevent it from being displaced due to vibration or external force during operation. When readjustment is needed, reverse the operation of the connection point of the pull rod 310 and the positioning rod 311 to release the locking of the positioning block 312 and the adjusting rod 309. At this time, the lead screw 313 transmission system can work again to perform a new height or position adjustment.

[0065] Specifically, by rotating the lead screw, the rotational motion can be accurately converted into the linear lifting motion of the lifting plate. This can achieve more accurate and continuous height or position adjustment than the previous sliding or rotational adjustment methods, meeting the higher precision requirements for the working position of the impact component. Through the articulated locking mechanism formed by the pull rod and the positioning rod, the adjusting rod can be effectively locked in a specific position. This locking mechanism ensures that during the operation of the tidal impact power generation device, the adjusting rod will not be accidentally displaced due to vibration, water flow impact or other external forces, thus maintaining the stable working state of the impact component. The combination of precise lead screw adjustment and reliable position locking enables the adjustment device to more flexibly and accurately adapt to position adjustments under different tidal conditions, water flow intensities or maintenance requirements, improving the adaptability and operating efficiency of the entire power generation device.

[0066] Specifically, the driving assembly includes a driving motor 401, a placing plate 402, a driving gear 403, a driven gear 404, a fixing plate 405, a driving wheel 406 and a driven wheel 407. The placing plate 402 is connected to the top end of the installation box 1, the driving motor 401 is connected to the bottom end of the placing plate 402, and the output end of the driving motor 401 is connected to the driving gear 403 through a machine hole 408; the driven gear 404 is connected to the top end of the placing plate 402 and meshes with the driving gear 403; the driving wheel 406 is connected to the top end of the driven gear 404, the fixing plate 405 is connected to the top end of the driving wheel 406, and the driven wheel 407 is connected to the bottom end of the fixing plate 405 and meshes with the driving wheel 406.

[0067] Specifically, when it is necessary to adjust the height of the impact assembly (or adjustment device), the control system issues an instruction to the driving motor 401 to start the motor. The driving motor 401 starts to rotate, and its output end drives the driving gear 403 to rotate through the machine hole 408. The driving gear 403 meshes with the driven gear 404 fixed on the placing plate 402. According to the gear transmission principle, the rotation of the driving gear 403 will drive the driven gear 404 to rotate in the opposite direction. The top end of the driven gear 404 is connected to the driving wheel 406, so the rotation of the driven gear 404 will directly drive the driving wheel 406 to rotate. The driving wheel 406 and the driven wheel 407 (usually connected by a chain or a synchronous belt, not clearly shown in the figure but this is a common way of such transmission) form a meshing or meshing transmission pair. The rotation of the driving wheel 406 will drive the driven wheel 407 to rotate through the chain / synchronous belt. The rotation of the driven wheel 407 will directly or indirectly (such as through a connecting shaft or a lead screw mechanism) drive the adjustment device (including a support rod, an arc-shaped rod, etc.) to perform a lifting motion. The up and down movement of the support rod, through the arc-shaped rod, long groove and other structures described before, finally realizes the height adjustment of the impact assembly. When the required height is adjusted, the control system stops the power supply of the driving motor 401, the adjustment device stops moving, and stays at the new position. The structure of the adjustment device itself (such as threaded connection, clamping mechanism, etc.) will provide a certain self-locking or positioning function to prevent accidental movement.

[0068] Specifically, through motor drive and gear transmission, precise and stable adjustment of the height of the impact assembly can be achieved, avoiding the inconvenience and insufficient accuracy of manual adjustment. The introduction of the driving assembly makes the height adjustment process automated, reduces manual intervention, and improves the operation efficiency and convenience. Adopting gear meshing and gear train transmission, the structure is relatively compact, the transmission ratio is stable, and the power can be reliably transmitted from the motor to the adjustment device. It can actively adjust the working position of the impact assembly according to the requirements of different tidal heights to obtain the best energy capture effect.

[0069] Specifically, as Figure 5As shown, the impact component includes a rotating shaft 501, a screw 502, an impact bracket 503, a connecting shaft 504, a tripod 505 and an impact plate 506. The rotating shaft 501 passes through the first mounting seat and is rotatably connected to the lifting plate 306. Third screw holes 507 are provided on the impact bracket 503. The screw 502 passes through the third screw holes 507 and is threadedly connected to the impact bracket 503. A sixth mounting seat 508 is provided on the impact plate 506. The impact bracket 503 is hinged to the tripod 505 through the connecting shaft 504. The tripod 505 respectively passes through the sixth mounting seat 508 and is rotatably connected to the impact plate 506.

[0070] Specifically, according to the expected tidal current direction and intensity, the initial position of the impact bracket 503 is adjusted by rotating the screw 502 to make it in the best stress state. When the tidal current impacts the impact plate 506, the impact force is transmitted to the impact bracket 503 through the tripod 505 and the connecting shaft 504, causing it to rotate around the connecting shaft 504. The rotation of the impact bracket 503 drives the rotation of the rotating shaft 501, converting the kinetic energy of the water flow into the rotational mechanical energy of the rotating shaft 501. During operation, according to the actual water flow conditions, the position of the impact bracket 503 can be finely adjusted by rotating the screw 502 to optimize the energy capture efficiency. The rotational movement of the rotating shaft 501 can be connected to a generator 602 to convert the mechanical energy into electrical energy, realizing the utilization of tidal energy.

[0071] Specifically, through the structural design of the impact plate, tripod and connecting shaft, the impact component can effectively capture the impact force of the tidal current and convert it into rotational mechanical energy. The introduction of the screw enables the stress point and rotation radius of the impact bracket to be adjusted, so as to adapt to tidal currents in different directions and intensities, improving the adaptability of the device and the energy capture efficiency. The impact bracket is hinged to the tripod through the connecting shaft, and the tripod is rotatably connected to the impact plate. This structural design not only ensures the rotational freedom of the impact bracket but also ensures the stability of the entire impact component. The impact component can be used in conjunction with the adjustment device described previously to precisely control the position and attitude of the impact component through the adjustment device, further optimizing the energy capture effect.

[0072] Specifically, the energy conversion device includes a top frame 601, a generator 602, a gear shaft 603, a rack 604, and a spring 605. The top frame 601 is connected to the top end of the installation box 1. The generator 602 is connected to the top end of the top frame 601. The gear shaft 603 is connected to the output end of the generator 602. A card slot 606 is provided on the top frame 601. The rack 604 passes through the card slot 606 and is slidably connected to the top frame 601, and meshes with the output ends of the gear shaft 603 and the rotating shaft 501 respectively. A limiting strip 607 is provided on the rack 604. The limiting strip 607 is slidably connected to the top frame 601. The spring 605 is fixedly sleeved on the limiting strip 607.

[0073] Specifically, the tidal impact force pushes the impact assembly, causing its rotating shaft 501 to rotate. The rotation of the rotating shaft 501 drives the rack 604 to perform a linear motion (e.g., move forward) in the card slot 606 of the top frame 601 through meshing. The linear motion of the rack 604 meshes with the gear shaft 603 at the same time, pushing the gear shaft 603 to rotate. The rotation of the gear shaft 603 directly drives the generator 602 to rotate, and the generator 602 starts generating electricity. When the impact force weakens or reverses, the elastic force of the spring 605 will push the rack 604 (possibly through the limiting strip 607) to move in the reverse direction (e.g., move backward), or buffer the impact on the rack 604. The reverse movement of the rack 604 may also drive the gear shaft 603 to rotate in the reverse direction or cause it to idle, depending on the design and the type of the generator 602. The sliding connection of the limiting strip 607 on the top frame 601 limits the excessive movement of the rack 604 and may help maintain the stability of the rack 604 during movement, preventing it from disengaging from the meshing or the card slot.

[0074] Specifically, the rotational motion of the impact assembly can be reliably transmitted to the generator through gear transmission, reducing energy loss. The addition of the spring provides the necessary restoring force for the system, helping the rack to reset during the impact gap or reverse, or buffering the impact, protecting the transmission components and the generator from excessive impact or maintaining continuous movement. Compared with long transmission shafts or other transmission methods, the rack and pinion mechanism can achieve the conversion of large-distance linear motion to rotational motion within a limited space. The design of the limiting strip and the top frame card slot ensures that the movement range of the rack is within a controllable range and provides an accurate guide for its linear motion, ensuring the stability and reliability of the meshing. As a relatively independent module, the energy conversion device is installed on the top frame and works in coordination with the impact assembly and the installation box, with a clear structure, facilitating installation and maintenance.

[0075] Specifically, as Figure 2 and Figure 6As shown in the figure, the clamping mechanism includes an impact side plate 701, a second bolt 702, a clamp 703, a disc spring 704, an auxiliary rod 705 and an auxiliary shaft 706. The connecting end of the clamp 703 is connected to the impact plate 506. A fourth screw hole 707 is provided on the clamp 703. The second bolt 702 passes through the fourth screw hole 707 and is threadedly connected to the clamp 703. A hinge seat 708 is provided on the clamp 703. The impact side plate 701 passes through the hinge seat 708 and is rotatably connected to the clamp 703. The auxiliary rod 705 is connected to the impact side plate 701. The top end of the auxiliary shaft 706 is connected to the auxiliary rod 705. A toothed rack 709 is provided on the top frame 601. The auxiliary shaft 706 meshes with the toothed rack 709. The disc spring 704 is connected to the auxiliary rod 705 and the clamp 703.

[0076] Specifically, the clamp 703 is connected to the impact plate 506 by the second bolt 702 and can rotate around the hinge seat 708. When the clamp 703 is in the closed state, the impact side plate 701 is in close contact with the impact plate 506 to achieve clamping; when the clamp 703 rotates around the hinge seat 708 to open, the impact side plate 701 is separated from the impact plate 506 to achieve release. The auxiliary rod 705 is connected to the impact side plate 701. The top end of the auxiliary shaft 706 is connected to the auxiliary rod 705 and can mesh with the toothed rack 709 on the top frame 601. By rotating the auxiliary shaft 706 (for example, through the linkage of the toothed rack 709), the auxiliary rod 705 can be pushed, thereby controlling the movement of the impact side plate 701 to achieve the opening or closing of the clamp 703. The disc spring 704 is connected between the auxiliary rod 705 and the clamp 703 to provide elastic force. When the clamp 703 is closed, the disc spring 704 can provide a certain pre-tightening force to enhance the clamping effect; when the clamp 703 is opened, the disc spring 704 can provide a restoring force to help the clamp 703 reset.

[0077] Specifically, through the mechanical clamping and releasing mechanism of the clamp, rapid clamping of the impact plate can be achieved, improving the installation and adjustment efficiency. The design of the auxiliary rod and the auxiliary shaft, especially the meshing with the toothed rack, enables the opening and closing of the clamping mechanism to be controlled through remote operation, facilitating clamping in an environment where direct operation is difficult. The pre-tightening force of the disc spring ensures that the clamp can reliably clamp the impact plate in the closed state, preventing loosening or falling off during the working process. The clamping mechanism can be applied to impact plates of different sizes and shapes, with strong adaptability.

[0078] Specifically, it further includes a fixed ear 8, and one end of the fixed ear 8 is connected to one end of the installation box 1.

[0079] Specifically, through its connection with the installation box 1, it provides additional support and fixing points for the entire device, enhancing the structural strength and stability of the device. It uses its own mechanical strength and reliable connection with the installation box 1 to effectively transfer the force acting on the device (such as tidal impact force, the device's own gravity, etc.) to the installation box 1, and further disperse it to a larger structure (such as a cliff base), thereby avoiding local damage or overall overturning of the device.

[0080] Specifically, as part of the mounting box, the fixing ears increase the overall structural strength of the device, enabling it to withstand greater external forces and improving the reliability of the device. The fixing ears provide additional support points for the device, enhancing the device's anti-overturning ability and stability, especially when it is subjected to a large impact force or the device itself is heavy. This effect is more obvious.

[0081] In another aspect, the present invention provides a cliff edge tidal impulse power generation method, comprising:

[0082] Step S1, a groove is made at a preset position of the cliff wall, and the installation box 1 is placed on the edge of the cliff by means of inlaying, so that the impact surface of the impact assembly faces outward to be impacted by the tide. In this process, under the action of the tidal impact, the clamping mechanism cooperates with the retraction and extension of the impact assembly, and its arc surface is retracted and expanded, so as to increase the force-bearing area for different degrees of tides;

[0083] Step S2, driving the device through the driving assembly to make the adjusting device move up and down, so as to fine-tune the height of the impact plate 506 to make it more suitable for the impact of tides at different heights, so as to adapt to the changes in the flood season and the dry season;

[0084] Step S3, driven by the impact component, the rack 604 of the driving component is lifted and slid, and when sliding, it drives the generator 602 meshed with it through the gear to generate electricity, and stores energy through the battery 203. The rectifier 204 converts energy in this process and cooperates with the transmission box 205 to transmit energy.

[0085] Specifically, the preset position refers to a position that can meet the requirements of efficient operation and structural safety of the tidal energy power generation device.

[0086] Specifically, the tidal current impacts the impact component, causing it to move (usually reciprocating up and down or swinging). The movement of the impact component is transmitted to the drive component through a mechanical connection (such as a connecting rod). If the drive component includes a rack 604, then the movement of the impact component will drive the rack 604 to slide in the vertical direction. The sliding rack 604 meshes with a pre-set gear (or gear set). According to the meshing relationship between the rack 604 and the gear, the linear reciprocating movement of the rack 604 is converted into the rotational movement of the gear. The rotational movement of the gear is directly or through a transmission shaft transmitted to the rotor of the generator 602, driving the generator 602 to rotate. During the rotation of the generator 602, alternating current (AC) is generated according to the principle of electromagnetic induction. Due to the reciprocity of the tides, the alternating current generated by the generator 602 may be pulsating or unstable. The rectifier 204 intervenes to convert the alternating current generated by the generator 602 into direct current (DC), and may perform filtering to make its voltage and current more stable. The rectified direct current first charges the battery 203 to store the electrical energy. At the same time, part or all of the direct current can be managed and distributed through the transmission switchboard 205, for example, directly supplied to nearby electrical equipment, or converted back into alternating current through an inverter and incorporated into the power grid, or transmitted remotely.

[0087] Specifically, the linear motion of the tides is efficiently converted into rotational motion through a rack-and-pinion mechanism to drive the generator to generate electricity, improving the conversion efficiency from mechanical energy to electrical energy. The use of the rectifier ensures that the output electrical energy is stable direct current suitable for storage or use, overcoming the inherent intermittency and volatility of tidal power generation. The addition of the battery enables energy storage, which can provide electricity during periods of weak tides or no tides, improving the energy utilization rate and power supply continuity. The transmission switchboard is responsible for the management, distribution, and transmission of electrical energy, making the entire power generation system more standardized and easier to control.
