Description

Technical Field

[0001] This invention patent relates to the field of marine underwater power generation equipment technology, and in particular to a double-layer blade hydroelectric power generation device and method with a coiled rope guide. Background Technology

[0002] In the development of the shipping industry, the issue of power supply for the continuous operation of small and medium-sized vessels has always been a key focus. To address the problem of insufficient power supply during ship navigation, underwater power generation devices have emerged. Their core working principle is to use the impact force of underwater currents to drive blades to rotate, which in turn drives a generator through a transmission mechanism, converting water energy into electrical energy. This provides supplementary power for the ship's navigation equipment, communication systems, and domestic needs, and is particularly suitable for scenarios where solar power and other methods are insufficient. It is an important technical solution for achieving "on-site" power supply.

[0003] However, current known shipborne underwater power generation devices, in practical applications, are subject to numerous technical defects due to the complex hydrological environments of oceans and inland rivers, as well as the limitations of traditional design concepts. These defects severely restrict their effectiveness and widespread application. The following section elaborates on these defects and shortcomings using specific existing technologies: 1. Insufficient reliability of fixed structure Existing shipboard underwater power generation devices generally rely on rigid, fixed structures to connect the hull and the power generation components. For example, in a small hydroelectric power station towed balanced high-efficiency hydroelectric power generation device like CN207500036U, although support columns and auxiliary rods are used for fixation, critical load-bearing components such as the connecting shaft between the blades and the generator are still prone to irreversible bending deformation under long-term water flow impact. This deformation not only directly shortens the service life of the equipment but also leads to frequent downtime for maintenance and disassembly, increasing operation and maintenance costs and the risk of ship operation interruption.

[0004] 2. The installation process is complex and inefficient. The installation process of traditional marine underwater power generation devices is complex and time-consuming. Taking an axial flow pump-hydroelectric generator set like CN215170504U9 as an example, although the equipment has a lifting function to adapt to changes in water level, its installation still requires positioning through diving operations or specialized large-scale hoisting equipment after the ship is launched. The installation process is greatly limited by environmental factors such as water flow speed, underwater visibility, and water temperature, and a single installation usually takes more than 8 hours, seriously affecting the overall operational progress of the ship. At the same time, diving operations also pose certain safety risks.

[0005] 3. Fluctuations in water flow velocity lead to unstable power generation. The fluctuation range of water flow velocity can reach 2-5 m / s in different water areas (such as nearshore and offshore, upstream and downstream of inland rivers) and at different times (such as high tide and low tide, flood season and dry season). Existing devices, such as a hydroelectric power generation device CN222542561U, although possessing certain height adjustment capabilities, still lack an effective flow velocity control mechanism. When the water flow velocity exceeds the blade's adaptability range, the blade may operate at overfrequency or underfrequency, resulting in frequent fluctuations in generator output power. This makes it impossible to stably match the ship's power demand, and may even damage the power generation components due to abnormal load.

[0006] 4. The blade structure design has inherent flaws. Traditional underwater power generation devices for ships mostly employ single-blade or helical blade structures. Taking single-blade devices as an example, they suffer from the problem of "insufficient water flow capture," with a large amount of water flow being lost without being effectively utilized. Helical blade devices, such as some undisclosed but similar designs, cause significant energy loss due to the vortex formed by the rotating water flow. This results in the current devices generally achieving a water-to-electricity conversion efficiency of less than 35%, leading to low energy utilization efficiency.

[0007] 5. Uneven stress on the blades makes them prone to damage. Traditional single-blade designs directly bear the entire impact force of the water flow, operating under high loads for extended periods, making them prone to cracks and breakages, further increasing maintenance frequency and operating costs. Meanwhile, the complex force direction of helical blades exacerbates wear and fatigue, affecting the long-term stable operation of the equipment.

[0008] 6. Assembly positioning accuracy is difficult to guarantee. In underwater environments, various forces such as water thrust and buoyancy can interfere with the assembly of equipment. Taking a hydroelectric power generation device similar to CN222542561U as an example, although it uses a winch and frame structure for height adjustment, it is still difficult to ensure that the generator and the entire blade assembly are precisely installed in the preset positions on the hull during the assembly process. In particular, the problem of the blades not being perpendicular to the water surface after assembly is common, which affects the contact angle between the blades and the water flow, reduces power generation efficiency, and may even cause a chain of failures such as blade wear and transmission mechanism jamming.

[0009] 7. Strong limitations in applicable scenarios The existing fixed structure and blade design of the device are poorly adaptable to hydrological environments, making it difficult to simultaneously adapt to different flow velocities and water qualities in oceans, inland rivers, and other scenarios. When water flow conditions exceed the device's design threshold, power generation efficiency drops sharply, and it may even fail to operate normally, limiting its application in diverse shipping scenarios.

[0010] In summary, current marine underwater power generation devices have significant shortcomings in terms of structural stability, ease of installation, power generation efficiency, adaptability, and operation and maintenance costs, making it difficult to meet the needs of small and medium-sized vessels for efficient, stable, and reliable supplemental power supply equipment. Therefore, developing a marine underwater power generation device that can withstand the impact of water flow, prevent bending of key components, is easy to install, can actively regulate water flow speed, and has optimized blade structure has become an urgent need for industry development. This is of great significance for improving vessel endurance, reducing shipping costs, and promoting the development of green shipping. Summary of the Invention

[0011] The technical problem solved by this invention is to provide a double-layer blade hydroelectric power generation device and method with a winding rope guide, which solves the technical problems of traditional marine hydroelectric power generation devices, such as easy bending of the connecting shaft, inconvenient installation, low power generation efficiency due to unstable water flow velocity, and insufficient water energy utilization due to unreasonable blade structure. Through multi-system collaborative design, the device achieves a comprehensive improvement in structural stability, ease of installation, and high power generation efficiency.

[0012] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides a double-layer blade hydroelectric power generation device and power generation method with a coiled rope guide, as detailed below: I. Overall Structure of the Device The core of the rope-guided double-layer blade hydroelectric power generation device of the present invention consists of six major systems. These systems work together to achieve efficient conversion of water energy into electrical energy. The specific connection relationships are as follows: The mounting system serves as the foundation for the entire device, directly connected to the hull, providing robust mounting support for the power generation system, stabilization system, and other systems. The power generation system is mounted on a fixed system and is connected to the transmission system via a plum blossom coupling. It is used to receive the torque transmitted by the transmission system and complete the conversion of electrical energy. One end of the transmission system is precisely matched with the power generation system, and the other end is fixedly assembled with the blade mechanism through its blade connecting shaft to realize power transmission and drive the blade mechanism to rotate. The flow guiding system is fixedly installed on the hull and is set in correspondence with the blade mechanism. The flow velocity and concentration of the water flowing towards the blade mechanism can be flexibly adjusted by rotating the guide plate and connecting shaft. The winch shaft of the stabilization system is installed on the fixed system, and its U-bolt is connected to the transmission system. The winch shaft and the U-bolt are fastened by a rope winding to achieve stable positioning and anti-bending protection of the device. The blade mechanism adopts a double-layer S-shaped blade design, which, together with the flow guiding system, allows for adjustment of the flow guide plate opening angle through the positioning pin, greatly improving the efficiency of water energy capture and the stability of power generation.

[0013] II. Detailed Structure of Each System 1. Power generation system The power generation system includes a motor, a motor support platform, a speed increaser, hollow sleeves, a connecting shaft, a speed increaser platform, and a perforated coupling.

The blade connecting shaft is connected to the connecting plate via the bearing housing assembly, allowing free rotation. A blade brake rod passes through the upper end of the blade connecting shaft. The brake plate fixing lug is connected to the rear side of the connecting plate via a tenon and mortise structure. The brake plate is detachably connected to the brake plate fixing lug via a tenon and mortise structure. A round hole is opened in the middle of the brake plate for connecting the brake plate opening tool for operation. The first and second bearing housings are fixed to the connecting plate with bolts and are fitted onto the middle section of the blade connecting shaft. U-bolts are symmetrically installed on both sides of the connecting plate for cooperation with the stabilization system.

[0015] 3. Blade mechanism The blade mechanism includes a first blade top plate, a second blade top plate, a third blade top plate, blades, a blade limiting ring, and a flange. The first blade top plate, blade, second blade top plate, blade, and third blade top plate are sequentially fitted onto the lower end of the blade connecting shaft from top to bottom. The layers are precisely connected by tenon and mortise structures, forming a double-layer S-shaped arrangement. A flange is installed above the first blade top plate for overall fixation of the blade mechanism. The blade limiting ring is fitted onto the bottom end of the blade connecting shaft to effectively prevent the blade mechanism from falling during operation.

[0016] 4. Flow diversion system The flow guiding system consists of a top plate of the flow guide frame, a flow guide plate coupling, a flow guide plate rotation wrench, a flow guide plate positioning pin, a flow guide plate, and a flow guide plate shaft limiting ring. The top plate of the flow guide frame is securely connected to the hull via threads, and the flow guide plate coupling is fitted into a circular hole at its front end. A flow guide plate shaft limiting ring is fitted into the lower end of the flow guide plate coupling to fix the flow guide plate. The upper end of the flow guide plate coupling is connected to the flow guide plate rotation wrench via a slot. The other end of the flow guide plate rotation wrench has a circular hole through which the flow guide plate positioning pin passes and can be inserted into different holes on the top plate of the flow guide frame, thereby achieving the fixation of the flow guide plate coupling and the flexible adjustment of the flow guide plate direction.

[0017] 5. Fixed system The fixing system includes a top plate of the hull plate connecting frame, vertical plates of the hull plate connecting frame, support ribs, long ribs of the hull plate connecting frame, short ribs of the hull plate connecting frame, blade reinforcing plates, and fixing ends. The top plate of the hull plate connecting frame is fixed to the hull by bolts with channel steel. The top plate of the hull plate connecting frame is connected to the vertical plates of the hull plate connecting frame by mortise and tenon joints. Support ribs are provided on both sides of the connection to enhance structural strength. The rear side of the vertical plates of the hull plate connecting frame has alternating long ribs and short ribs of the hull plate connecting frame. The lower side is connected to the fixing end by double bolts, and the upper side is provided with blade reinforcing plates. The other side is connected to the connecting plate of the transmission system. The top plate of the hull plate connecting frame also provides the installation foundation for the winch support plates of the power generation system and the stabilization system.

[0018] 6. Stable System The stabilization system includes a connecting plate, a winch support plate, a winch base, a winch shaft, a winch shaft cover, a winch wire wheel, a straight tooth, a winch shaft spike wheel, a winch cover, a spike wheel clip, and U-bolts. The connecting plate is fixedly connected to the winch base via the winch support plate. The winch shaft is mounted on the winch base, and winch shaft covers are installed at both ends of the winch shaft. The winch wire wheel, straight tooth, and winch shaft spike wheel are sequentially fitted on the winch shaft. The winch cover is installed on the outside of the straight tooth. The spike wheel clip cooperates with the winch shaft spike wheel to achieve limit positioning. The rope is wound around the winch wire wheel, and both ends are connected and fixed to the winch shaft and U-bolts, respectively.

[0019] III. Power Generation Methods Based on the above-mentioned double-layer blade hydroelectric power generation device with winding rope guide, the present invention also provides a method for generating electricity using a double-layer blade hydroelectric power generation device with winding rope guide, specifically including the following steps: Step 1, Device Installation and Debugging: Place the successfully debugged device in the initial position, ensuring that the blade connecting shaft of the transmission system and the guide plate connecting shaft of the guide system remain parallel; press the device underwater, and tighten the winch shaft and U-bolts with the stabilizing system's winding rope to ensure that the device does not shift left or right and that the blades are perpendicular to the water surface; complete the assembly and connection of various components such as the power generation system and transmission system, ensuring that the motor support platform of the power generation system, the speed increaser platform, and the connecting plate of the transmission system are precisely connected to the connecting shaft through hollow sleeves, and that the coaxiality error between the power generation system and the transmission system is ≤0.5mm.

[0020] Step 2, Device Start-up: After confirming that the winding rope connection is secure, use the brake plate opening tool to control the brake plate, release it from the bearing housing assembly, and start the device to enter the operating state.

[0021] Step 3, Water-to-Electricity Conversion: After being guided by the flow diversion system, the water impacts the blades of the blade mechanism, causing the blade mechanism to rotate; the blade connecting shaft rotates stably under the support of the bearing housing assembly, which in turn drives the plum blossom coupling to rotate. The torque is accelerated by the speed increaser and then transmitted to the motor of the power generation system, realizing the conversion of water energy into electrical energy; by monitoring the electrical energy conversion efficiency in real time, it is determined whether the current water flow rate is within a reasonable range.

[0022] Step 4, Flow Rate Adjustment: The preset optimal water flow rate range is 1.5~2.5m / s. When the power conversion efficiency is lower than the set percentage, the flow rate is determined to be outside the optimal range. If the water flow rate is too fast, the guide plate positioning pin is inserted into the corresponding hole on the top plate of the guide shroud frame to increase the opening angle of the guide plate and reduce the water flow rate. If the water flow rate is too slow, the insertion hole of the guide plate positioning pin is adjusted to reduce the opening angle of the guide plate to improve the concentration of the water flow, ensuring that the flow rate is stable within the preset range and guaranteeing power generation efficiency.

[0023] This invention solves the problems of easy bending of the connecting shaft and inconvenient installation of traditional devices by using a rope-type stabilizing structure. It achieves active regulation of water flow velocity through a flow guiding system and improves water energy capture rate and conversion efficiency by combining a double-layer S-shaped blade mechanism. The overall structure is reasonably designed and operates stably, making it suitable for the on-site power generation needs of various small and medium-sized ships.

[0024] The rope-guided double-layer blade hydroelectric power generation device and method provided by the present invention have the following beneficial effects: 1. Extended equipment lifespan: The stabilization system of this invention adopts a flexible constraint structure of "rope winding + winch", which enables the equipment to operate continuously for 3000 hours in a water flow with a speed of 4m / s, and the bending deformation of the main body is controlled within 0.5mm, which extends the lifespan of the equipment by more than 2 times compared with the traditional rigid fixed structure equipment.

[0025] 2. Enhanced equipment bending resistance: The flexible constraint structure of the "rope winding + winch" of the stabilization system of this invention can dynamically adjust tension and disperse impact force, further enhancing bending resistance and improving the overall stability of the equipment under water flow impact.

[0026] 3. Reduced maintenance frequency and cost: The structural optimization and material improvement of this invention, as well as the low failure characteristics of the stable system, reduce the equipment maintenance frequency by 60% or more, significantly reducing maintenance expenses caused by equipment damage, and reducing maintenance downtime and spare parts procurement and replacement costs.

[0027] 4. Stable power output: The valve-type regulating device of this invention ensures that the generator operates in the optimal flow velocity range of 1.5~2.5m / s, effectively coping with water flow velocity fluctuations of 2~5m / s in different water areas and at different times; the flow guiding system precisely adjusts the opening and closing angle of the flow guiding plate through the positioning pin of the flow guiding plate to stabilize the water flow velocity entering the equipment and ensure stable output power.

[0028] 5. Improve water capture rate: The double-layer vertical extraction blade design of this invention realizes "water flow relay capture". The water flow that is not fully utilized by the upper blade is captured a second time by the lower blade, and the water flow utilization rate is increased by more than 40% compared with the traditional single-layer blade.

[0029] 6. Reduced eddy current loss: The vertical blade structure of this invention allows water to flow smoothly along the blade surface, avoiding the eddy current phenomenon generated by traditional spiral blades, reducing eddy current loss by 35% or more, and optimizing the energy transfer path.

[0030] 7. Improved energy utilization efficiency: This invention combines improved water flow utilization with reduced eddy current loss, resulting in a significant increase in water energy conversion efficiency, far exceeding the conversion efficiency of traditional equipment, which is generally below 35%.

[0031] 8. Optimize blade stress: The blade mechanism of this invention features a double-layered S-shaped staggered arrangement, which evenly distributes the water flow impact force to the two layers of blades. This significantly reduces the load intensity borne by a single blade, preventing blade failure due to long-term high-load operation. The double-layered vertically withdrawable blade structure can also disperse the water flow impact force, enhancing blade reliability.

[0032] 9. Enhanced shaft rotation stability: The dual support structure of the first and second bearing seats in the transmission system of this invention, combined with the precise transmission of the plum blossom coupling, reduces the axial movement of the blade connecting shaft and torque transmission loss.

[0033] 10. Improved installation convenience: This invention can complete the pre-fixation of the rope and winch before the ship is launched, eliminating the need for temporary assembly underwater or on-site. The installation time for a single installation is reduced from more than 8 hours with traditional equipment to less than 2 hours.

[0034] 11. No-diving installation reduces risks: After the equipment of this invention is launched into the water, it can be fixed by simply operating the winch to tighten the rope through the deck control console. No diving operation is required, thus avoiding the safety risks and environmental limitations of underwater operations.

[0035] 12. Meeting the stable power needs of ships: The stable power output of this invention ensures that the generator can operate stably in different waters and at different times, meeting the continuous power needs of ships.

[0036] 13. Enhanced equipment adaptability: The intelligent flow rate regulation system of this invention enables the equipment to automatically adapt to changes in water flow rate in different water areas and time periods; the modular structure and the flexible constraint function of the stabilization system make the device suitable for various hydrological scenarios such as oceans and inland rivers.

[0037] 14. Improved hull adaptability: The alternating connection structure of long and short ribs in the hull plate connecting frame of the present invention can adapt to different hull profiles and flexibly adjust the installation position and fixing method.

[0038] 15. Reduce the risk of equipment damage: The flexible fastening structure of the present invention effectively absorbs the impact force of water flow, reducing the risk of equipment damage caused by long-term water flow impact.

[0039] 16. Multiple fixing to prevent displacement: The fixing system of the present invention uses a triple structure of channel steel bolting on the top plate of the ship plate connecting frame, lug fixing of U-shaped hanger hooks, and right-angle reinforcement of support ribs to ensure that the device does not deviate or move during ship navigation.

[0040] 17. Extending the range of ships: The device of this invention serves as a supplement to power supply methods such as solar power generation, enabling "on-site" power generation, solving the problem of insufficient power supply for small and medium-sized ships during long voyages or cloudy days, and extending the range and operating area.

[0041] 18. Improved maintenance convenience: The core components of this invention adopt a detachable assembly design. For example, the winch shaft cover and winch cover of the stabilization system, the flange and blade limit ring of the blade mechanism can all be disassembled and replaced individually.

[0042] 19. Lowering the operational threshold: The brake plate opening tool of this invention can quickly switch the braking state, and the multi-level adjustment function of the flow guiding system can complete the flow rate adaptation without professional technicians, and ordinary crew members can operate it proficiently.

[0050] Example 2 In another preferred embodiment, based on embodiment 1, such as Figure 9 As shown, this embodiment provides a method for generating hydroelectric power using a double-layered blade with a winding rope guide, based on the double-layered blade hydroelectric power generation device of Embodiment 1 above. The specific steps are as follows: Step 1, Installation and Debugging: Place the successfully debugged rope-driven hydroelectric generator in the initial position, ensuring that the blade connecting shaft 202 of the transmission system 2 and the guide plate connecting shaft 402 of the guide system 4 remain parallel; press the device underwater, and use the rope of the stabilizing system 6 to tighten the winch shaft 606 and U-bolt 602 to ensure that the device does not shift left or right, and that the blades 304 are perpendicular to the water surface; then complete the assembly and connection of various components and systems such as the power generation system 1, transmission system 2, and blade mechanism 3, ensuring that the connection of each component is reliable. Among them, the motor support platform 102 and speed increaser platform 106 of the power generation system 1 are precisely connected to the connecting plate 201 of the transmission system 2 through the hollow sleeve 104 and the connecting shaft 105.

[0051] Step 2, Device Start-up: Operate the brake plate 204 using the brake plate opening tool 205 to release it from the bearing housing assembly 207; check again the tightness of the rope winding between the winch seat 609 and the U-bolt 602, and start the device after confirming that there are no problems.

[0052] Step 3, Water-to-Electricity Conversion: The water flow impacts the blades 304 of the blade mechanism 3, causing the blade mechanism 3 to rotate. The upper and lower S-shaped arrangement of the blades 304 drives the blade connecting shaft 202 to rotate. The blade connecting shaft 202 rotates smoothly under the support of the first bearing seat 208 and the second bearing seat 209, thereby driving the plum blossom coupling 107 to rotate and transmitting power to the speed increaser 103. After being accelerated by the speed increaser 103, the energy is transmitted to the motor 101, realizing the conversion of water energy into electrical energy. By monitoring the electrical energy conversion efficiency, it is determined whether the current water flow rate is appropriate.

[0053] Step 4, Flow Rate Adjustment: If the monitoring detects that the water flow rate is too fast, fix the guide plate positioning pin 404 at the front end of the guide plate rotation wrench 403 to the corresponding hole on the top plate 401 of the guide shroud frame, and rotate the guide plate connecting shaft 402 to increase the opening angle of the guide plate 405 and reduce the water flow impact speed; if the water flow rate is too slow, adjust the hole position of the guide plate positioning pin 404 in the same way, and rotate the guide plate connecting shaft 402 to reduce the opening angle of the guide plate 405, improve the water flow concentration, and ensure that the water flow rate entering the power generation system 1 is within a stable operating range to ensure power generation efficiency.

[0054] Example 3 In another preferred embodiment, based on Embodiment 1, this embodiment provides a double-layer blade hydroelectric power generation device with a winding rope guide. It focuses on the assembly precision of each system and the stability of component fit, and is suitable for small and medium-sized ships with high installation reliability requirements. The core consists of a power generation system 1, a transmission system 2, a blade mechanism 3, a guide system 4, a fixing system 5, and a stabilization system 6, assembled according to a precise assembly logic. Details are as follows: During the assembly of the power generation system 1, the motor 101 is precisely aligned with the motor support platform 102 through four positioning pinholes and then tightened. The four hollow sleeves 104 below the motor support platform 102 are arranged in a rectangular shape. The connecting shaft 105 passes through the hollow sleeves 104 and is screwed into the threaded hole at the bottom of the motor support platform 102 for fixation. The other end of the connecting shaft 105 is inserted into the positioning hole of the speed increaser platform 106. The speed increaser 103 is horizontally fixed in the mounting groove of the speed increaser platform 106. The output end of the speed increaser 103 is engaged with one end of the plum blossom coupling 107. The other end of the plum blossom coupling 107 is reserved with a mating interface for the transmission system 2 to ensure the coaxiality of torque transmission.

[0055] In the transmission system 2, the connecting plate 201 is first pre-fixed to the blade reinforcing plate 507 of the fixing system 5 by bolts. The bearing seat assembly 207 is embedded in the preset mounting hole of the connecting plate 201. After the blade connecting shaft 202 passes through the center of the bearing seat assembly 207, the upper end round hole is clearance-fitted with the blade brake rod 203. The brake plate fixing ear plate 206 is embedded in the groove on the side and rear of the connecting plate 201 by mortise and tenon structure. After the brake plate 204 is mortised and tenoned with the brake plate fixing ear plate 206, the middle round hole is movably connected with the brake plate opening tool 205. The first bearing seat 208 and the second bearing seat 209 are symmetrically sleeved on the middle section of the blade connecting shaft 202 and locked to the connecting plate 601 by four fastening bolts to ensure that the blade connecting shaft 202 rotates without movement.

[0056] In the blade mechanism 3, the lower end of the blade connecting shaft 202 is sequentially fitted with the first blade top plate 301, the blade 304, the second blade top plate 302, the blade 304, and the third blade top plate 303. Each layer of components is positioned by a tenon and mortise structure. The two layers of blades 304 are staggered in an S-shape, and the included angle between adjacent blades 304 is maintained at a preset angle. The flange 306 above the first blade top plate 301 is tightened by bolts to make each layer of components fit tightly. The blade limiting ring 305 at the bottom of the blade connecting shaft 202 is screwed into the shaft thread to axially limit the blade structure from the bottom.

[0057] In the flow guiding system 4, the top plate 401 of the flow guide frame is fixed to the hull deck by expansion bolts, and its front end round hole is clearance-fitted with the flow guide plate connecting shaft 402. The flow guide plate 405 and the flow guide plate shaft limiting ring 406 are sequentially mounted on the lower end of the flow guide plate connecting shaft 402. The flow guide plate shaft limiting ring 406 is fixed by cotter pins. The slot at the upper end of the flow guide plate connecting shaft 402 engages with the locking block of the flow guide plate rotating wrench 403. The round hole at the other end of the flow guide plate rotating wrench 403 is transition-fitted with the flow guide plate positioning pin 404. Multiple positioning holes are preset on the top plate 401 of the flow guide frame for multi-position fixing of the flow guide plate positioning pin 404.

[0058] In the fixing system 5, the top plate 501 of the ship plate connecting frame is first fixed to the hull frame by welding with channel steel, and then reinforced with threaded fasteners. After the vertical plate 502 of the ship plate connecting frame is mortised and tenoned with the top plate 501 of the ship plate connecting frame, the supporting ribs 503 on both sides of the connection are welded to the two respectively to form a right-angle reinforcement structure. The long rib 504 and the short rib 505 of the ship plate connecting frame on the rear side of the vertical plate 502 of the ship plate connecting frame are alternately welded to the hull. The fixed end 508 on the lower side is fastened to the side plate of the hull by double bolts. The blade reinforcing plate 507 on the upper side is attached to the connecting plate 201 and then bolted. The U-shaped hanger hook 506 hooks the pre-set lifting lug of the hull to help fix the top plate 501 of the ship plate connecting frame.

[0059] In the stabilization system 6, the winch support plate 603 is welded to the top plate 501 of the ship plate connecting frame, and the winch seat 609 is fixed to the winch support plate 603 by bolts; after the winch shaft 606 passes through the shaft hole of the winch seat 609, the two ends are fitted with winch shaft covers 604, and the winch shaft 606 is sequentially fitted with a winch wire wheel 610, a straight tooth 611, and a winch shaft spike wheel 605. The straight tooth 611 meshes with the winch wire wheel 610, and the winch shaft spike wheel 605 cooperates with the spike wheel clip 607 to achieve unidirectional limiting; the winch cover 608 is fixed to the outside of the winch seat 609 by bolts to close the internal components; the U-bolts 602 on both sides of the connecting plate 601 are fixed to one end of the rope on the winch wire wheel 610, and the other end of the rope is wound around the winch wire wheel 610. The rope is tightened or loosened by rotating the winch shaft 606.

[0060] Example 4 In another preferred embodiment, based on embodiments 1 to 3, this embodiment provides a method for generating hydroelectric power using a double-layered blade with a wound rope guide. It optimizes the assembled double-layered blade hydroelectric power generation device based on embodiment 3, and combines the device's fixed calibration and output power monitoring process to provide a more practical working method. The steps are as follows: Step 1, Device Fixing and Verification: Install the optimized assembly device at the preset position on the hull using the fixing system 5. The top plate 501 of the hull plate connecting frame is fixed to the U-shaped hanger hook 506 by welding channel steel. The support rib 503, the long rib 504 of the hull plate connecting frame, and the short rib 505 of the hull plate connecting frame are firmly attached to the hull. Start the stabilization system 6 and rotate the winch shaft 606 to tighten the winding rope, so that the winding rope between the U-bolt 602 and the winch shaft 606 remains taut. Check whether the device has no left or right deviation or up and down movement. If the fixation is ineffective, disassemble and readjust the assembly position until the fixation requirements are met.

[0061] Step 2, underwater deployment: Place the qualified device underwater, ensuring that the blade mechanism 3 is completely submerged. Adjust the device's attitude so that the blade connecting shaft 202 of the transmission system 2 is parallel to the guide plate connecting shaft 402 of the flow guiding system 4, and the blades 304 are perpendicular to the water surface. Check the tightness of the winding rope and the reliability of the connections of each system again. After confirming that no parts are loose, the underwater deployment is completed.

[0062] Step 3, Pre-adjustment of flow rate: Based on the initial water flow conditions of the water area, adjust the angle of the guide plate 405 by turning the wrench 403 on the guide plate, insert the guide plate positioning pin 404 into the corresponding positioning hole on the top plate 401 of the guide shroud frame, so that the opening angle of the guide plate 405 is in the middle position, laying the foundation for subsequent precise adjustment.

[0063] Device startup: Operate brake plate 204 by using brake plate opening tool 205 to release it from the restraint of bearing housing assembly 207 and release the rotation restriction of blade connecting shaft 202; reconfirm the tension of the winding rope and the connection status of each component, and start motor 101 of power generation system 1 after confirming that there are no errors, and enter trial operation state.

[0064] Step 4, Power Conversion and Power Monitoring: After the water flows through the guide system 4, it impacts the blades 304, causing the blade mechanism 3 to rotate. The two layers of S-shaped blades 304 are linked to the blade connecting shaft 202, and rotate smoothly under the support of the first bearing seat 208 and the second bearing seat 209. The torque is transmitted to the speed increaser 103 through the plum blossom coupling 107, and after acceleration, it drives the motor 101 to realize the conversion of water energy to electrical energy. The output power of the motor 101 is monitored in real time to determine whether the current power generation status is normal.

[0065] Step 5, Precise Flow Rate Adjustment: If the output power is lower than the preset value, it means that the water flow rate deviates from the optimal range. Adjust the insertion position of the guide plate positioning pin 404 by rotating the guide plate wrench 403: if the flow rate is too fast, increase the opening angle of the guide plate 405 to expand the water inlet cross section and reduce water flow impact; if the flow rate is too slow, decrease the opening angle of the guide plate 405 to increase the water flow concentration; repeatedly adjust until the output power is stable and the device enters normal working state.

[0066] Example 5 In another preferred embodiment, based on embodiments 1 to 4, this embodiment provides a double-layer blade hydroelectric power generation device with a winding rope guide. It is optimized for adaptability to different hydrological environments such as nearshore and inland rivers. The core consists of a power generation system 1, a transmission system 2, a blade mechanism 3, a guide system 4, a fixing system 5, and a stabilization system 6. The structural layout of each system is strictly designed according to the attached drawings, as detailed below: like Figure 1 As shown, the device adopts a modular assembly structure. The power generation system 1, transmission system 2, and blade mechanism 3 are connected sequentially from top to bottom. The flow guiding system 4 is set at the front end of the blade mechanism 3. The fixing system 5 and the stabilizing system 6 provide fixed support from the hull connection end and the mid-stress point, respectively, to ensure the overall force balance.

[0067] In power generation system 1, such as Figure 2 As shown, the motor 101 is fixed to the motor support platform 102 through four pinholes. The motor support platform 102 and the speed increaser platform 106 are rigidly supported by four hollow sleeves 104 and a connecting shaft 105. The connecting shaft 105 passes through the hollow sleeves 104 and is threaded to the two platforms. The plum blossom coupling 107 is located on the bottom side of the speed increaser 103, precisely connecting the output end of the speed increaser 103 with the power input end of the transmission system 2 to ensure stable torque transmission.

[0068] Transmission system 2 (refer to) Figure 3 The component layout shown includes a connecting plate 201 as the core load-bearing component, a bearing housing assembly 207 embedded in a pre-drilled hole in the connecting plate 201, and a blade connecting shaft 202 that can rotate freely after passing through the bearing housing assembly 207. A blade brake rod 203 is inserted through a round hole at the upper end of the blade connecting shaft 202. A brake plate 204 is tenon-and-mortise connected to the connecting plate 201 via a brake plate fixing lug 206. A brake plate opening tool 205 engages with a round hole in the middle of the brake plate 204 to achieve rapid switching of the braking state. A first bearing housing 208 and a second bearing housing 209 are symmetrically fixed to the middle section of the blade connecting shaft 202 to further improve the rotational stability of the shaft system.

[0069] In blade mechanism 3, such as Figure 4As shown, the lower end of the blade connecting shaft 202 is assembled in the following order: first blade top plate 301, blade 304, second blade top plate 302, blade 304, and third blade top plate 303. The layers are positioned using a tenon and mortise structure. The two layers of blades 304 are staggered in an S-shape, significantly increasing the water flow capture area compared to traditional single-layer blades. The flange 306 above the first blade top plate 301 is secured with bolts. The blade limiting ring 305 at the bottom of the blade connecting shaft 202 effectively prevents axial movement of the blade structure. Figure 4 The limiting structure shown fits snugly against the bottom of blade 304, ensuring that there is no loosening during rotation.

[0070] The flow diversion system 4 strictly follows the guidelines. Figure 5 As shown in the structural design, the top plate 401 of the fairing frame is fixed to the hull by threads, and the front end of the fairing frame has a round hole for the fairing plate connecting shaft 402. The lower end of the fairing plate connecting shaft 402 is connected to the fairing plate 405 and the fairing plate shaft limiting ring 406 in sequence. The fairing plate shaft limiting ring 406 is locked by a cotter pin. The upper end of the fairing plate connecting shaft 402 is connected to the groove of the fairing plate rotating wrench 403. After the fairing plate positioning pin shaft 404 passes through the round hole of the fairing plate rotating wrench 403, it can be inserted into the preset multi-position hole of the fairing frame top plate 401 to achieve precise adjustment of the opening angle of the fairing plate 405 and adapt to different flow velocity environments.

[0071] In fixed system 5, such as Figure 6 As shown, the top plate 501 of the ship plate connecting frame is bolted to the hull by channel steel, and the vertical plate 502 of the ship plate connecting frame is tenon-and tenoned with the top plate 501 of the ship plate connecting frame. The supporting ribs 503 on both sides of the connection point form a right-angle reinforcement structure. The long ribs 504 and short ribs 505 of the ship plate connecting frame are alternately arranged on the rear side of the vertical plate 502 of the ship plate connecting frame to enhance the connection strength with the hull. The fixed end 508 on the lower side is fastened to the hull by double bolts. The blade reinforcing plate 507 on the upper side is attached and fixed to the connecting plate 201 of the transmission system 2. The U-shaped hanger hook 506 hooks the pre-set lifting lug of the hull to form a double fixation.

[0072] Stable System 6 Reference Figure 7 and Figure 8 As shown in Figure 2, the winch support plate 603 is fixed to the top plate 501 of the ship plate connecting frame, and the winch seat 609 is bolted to the winch support plate 603. The winch shaft 606 passes through the shaft hole of the winch seat 609, and the two ends are fitted with winch shaft covers 604. The winch shaft 606 is sequentially fitted with a winch wire wheel 610, a spur tooth 611, and a winch shaft spike wheel 605. The spur tooth 611 meshes with the winch wire wheel 610 for transmission, and the spike wheel clip 607 cooperates with the winch shaft spike wheel 605 to achieve unidirectional limiting. The U-bolts 602 on both sides of the connecting plate 601 are fixed to the rope on the winch wire wheel 610. The flexible constraint of the rope offsets the impact force of the water flow. As shown in Figure 2, this structure can dynamically adjust the tension to avoid bending of the blade connecting shaft 202.

[0073] Example 6 In another preferred embodiment, based on embodiments 1 to 5, this embodiment provides a method for generating hydroelectric power using a double-layered blade with a winding rope guide, based on the multi-water-adaptive winding rope guide double-layered blade hydroelectric power generation device of embodiment 5, combined with the attached... Figure 9 The workflow shown provides a standardized operating method, with the following steps: Step 1, Device Fixing and Verification: (e.g.) Figure 9 As shown, the device is first installed on the ship using the fixing system 5. Initial fixing is achieved through welding the channel steel of the top plate 501 of the ship's plate connecting frame, fixing the lifting lugs of the U-shaped bracket hooks 506, and reinforcing the supporting ribs 503. The stabilization system 6 is then activated, and the winch shaft 606 is rotated to tighten the rope, ensuring the rope between the U-bolt 602 and the winch shaft 606 remains taut. The device is then checked for lateral or vertical movement. If the fixing is ineffective (e.g....), the device will be considered fixed. Figure 9 (As shown in the process judgment), after disassembly, readjust the assembly position until the fixing requirements are met.

[0074] Step 2, Underwater Deployment: Place the qualified device underwater, ensuring that the blade mechanism 3 is completely submerged in the water. Adjust the device's attitude so that the blade connecting shaft 202 of the transmission system 2 is parallel to the guide plate connecting shaft 402 of the flow guiding system 4, and the blades 304 are perpendicular to the water surface. Check the tightness of the winding rope and the tightness of the connecting bolts of each system again. After confirming that no parts are loose, the underwater deployment is complete.

[0075] Step 3, Flow Pre-adjustment: Based on the initial water flow conditions of the water area, and the structure of the flow guiding system 4, hold the wrench 403 to adjust the rotation angle of the flow guiding plate connecting shaft 402, insert the flow guiding plate positioning pin 404 into the corresponding hole on the top plate 401 of the flow guiding cover frame, so that the opening angle of the flow guiding plate 405 is in the initial position that is suitable for the current water flow rate, laying the foundation for subsequent precise adjustment.

[0076] Step 4, Device Start-up: Operate the brake plate 204 using the brake plate opening tool 205 to release it from the restraint on the bearing housing assembly 207 and release the rotation restriction of the blade connecting shaft 202; reconfirm the rope tension, the vertical state of the blade 304, and the reliability of the connection of each component. After confirming that everything is correct, start the motor 101 of the power generation system 1, and the device enters the trial operation state.

[0077] Step 5, Energy Conversion and Power Monitoring: After the water flows through the guide plate 405 of the flow guiding system 4, it impacts the blades 304 of the blade mechanism 3, causing the blade mechanism 3 to rotate. The two layers of S-shaped blades 304 are linked to the blade connecting shaft 202, and rotate smoothly under the support of the first bearing seat 208 and the second bearing seat 209. The torque is transmitted to the speed increaser 103 through the plum blossom coupling 107 for acceleration, and then drives the motor 101 to realize the conversion of water energy into electrical energy; Figure 9 As shown, the output power of motor 101 is checked in real time to determine whether the power generation status is normal.

[0078] Step 6, Precise Flow Rate Adjustment and Normal Operation: If the output power is abnormal, it indicates that the water flow rate deviates from the optimal range. Adjust the insertion position of the guide plate positioning pin 404 by rotating the guide plate lever 403: If the flow rate is too fast, increase the opening angle of the guide plate 405 to enlarge the inlet cross-section and reduce the water flow impact velocity; if the flow rate is too slow, decrease the opening angle of the guide plate 405 to increase the water flow concentration; repeatedly adjust until the output power is stable, and the device is set to... Figure 9 The process shown has entered normal working status.

[0079] In a preferred embodiment, the power generation system 1 includes a motor 101 mounted on a motor support platform 102. Four hollow sleeves 104 are connected below the motor support platform 102. A connecting shaft 105 passes through the hollow sleeves 104 and is threadedly connected to the motor support platform 102. The other end of the connecting shaft 105 is connected to a speed increaser platform 106. A speed increaser 103 is mounted on the speed increaser platform 106. A perforated coupling 107 connects the speed increaser 103 to the transmission system 2. This configuration ensures that the power generated by the motor 101 is stably transmitted to the speed increaser 103 via the hollow sleeves 104 and the connecting shaft 105. The speed increaser 103 then accurately transmits torque to the transmission system 2 via the perforated coupling 107, achieving efficient power conversion and transmission and ensuring stable operation of the power generation system.

[0080] In a preferred embodiment, the transmission system 2 includes a connecting plate 201 and a blade connecting shaft 202. The blade connecting shaft 202 is connected to the connecting plate 201 via a bearing housing assembly 207 and can rotate freely. A blade brake rod 203 is inserted through the upper end of the blade connecting shaft 202. A brake plate fixing ear plate 206 is connected to the rear side of the connecting plate 201 via a tenon and mortise structure. A brake plate 204 is connected to the brake plate fixing ear plate 206 via a tenon and mortise structure.

A first bearing housing 208 and a second bearing housing 209 are connected to the connecting plate 602 via bolts and are sleeved on the middle section of the blade connecting shaft 202. U-bolts 603 are installed on both sides of the connecting plate 602. The above configuration makes the blade connecting shaft 202 more stable during operation and reduces shaking. When the blades need to be braked, the brake plate 204 is pulled by the brake plate opening tool 205. The brake plate 204 drives the blade brake rod 203, thereby braking the blade connecting shaft 202 and ensuring the safe operation of the equipment.

[0081] In a preferred embodiment, the blade mechanism 3 includes a first blade top plate 301, a second blade top plate 302, a third blade top plate 303, and blades 304. The first blade top plate 301, blades 304, second blade top plate 302, blades 304, and third blade top plate 303 are sequentially fitted onto the lower end of the blade connecting shaft 202 from top to bottom, with each layer connected by tenon and mortise joints. A flange 306 is installed above the first blade top plate 301 to fix the blade mechanism 3, and a blade limiting ring 305 is fitted onto the lowermost end of the blade connecting shaft 202 to prevent the blade mechanism 3 from falling. These features ensure that the blade mechanism 3 is structurally stable during operation and that the components fit tightly together. The tenon and mortise joints enhance the overall strength and stability, while the flange 306 and blade limiting ring 305 effectively limit the displacement of the blade mechanism, ensuring the safety and reliability of the equipment during operation.

[0082] In a preferred embodiment, the flow guiding system 4 includes a top plate 401 of a flow guide frame, which is connected to the hull via threads. A flow guide plate connecting shaft 402 is fitted into a circular hole at its front end. A flow guide plate shaft limiting ring 406 is fitted into the lower end of the flow guide plate connecting shaft 402 to fix the flow guide plate 405. A flow guide plate rotating wrench 403 is connected to the upper end of the flow guide plate connecting shaft 402 via a slot. A circular hole is provided at the other end of the flow guide plate rotating wrench 403, through which a flow guide plate positioning pin 404 passes and is inserted into different holes in the top plate 401 of the flow guide frame to fix the flow guide plate connecting shaft 402 and adjust the direction of the flow guide plate 405. The above configuration allows the flow guide plate 405 to rotate flexibly according to the direction of water flow. By inserting the flow guide plate positioning pin 404 into different holes, multi-angle precise positioning can be achieved, effectively improving the stability of ship navigation, reducing water flow resistance, and optimizing the overall flow guiding performance.

[0083] In a preferred embodiment, the fixing system 5 includes a top plate 501 of the ship plate connecting frame, which is bolted to the hull by channel steel. The top plate 501 is connected to the vertical plate 502 of the ship plate connecting frame by mortise and tenon joints, and support ribs 503 are provided on both sides of the connection. Long ribs 504 and short ribs 505 of the ship plate connecting frame are alternately arranged on the rear side of the vertical plate 502. The lower side is connected to the fixing end 508 by double bolts, and the upper side is provided with a blade reinforcing plate 507. The other side is connected to the connecting plate 201 of the transmission system 2. The top plate 501 of the ship plate connecting frame is connected to the winch support plate 6 of the power generation system 1 and the stabilization system 6. 04; The above configuration, the fixing system 5, is combined with the channel steel bolts and mortise and tenon structure to firmly connect the hull and the power generation device. The support ribs 503 and the alternating arrangement of long and short ribs enhance the overall rigidity. Double bolt fixing ensures the stability of the lower side. The blade reinforcing plate 507 is connected to the transmission system 2 connecting plate 201 to transmit force and reduce vibration. The winch support plate 604 is connected to the fixing system 5. Together, they provide reliable support for the equipment in the complex underwater environment and ensure the continuous operation of power generation. This improves the stability and impact resistance of the equipment installation, reduces displacement and damage caused by water flow impact, extends the service life of the equipment, reduces maintenance costs, and ensures the stable and efficient operation of the power generation system 1.

[0084] In a preferred embodiment, the stabilizing system 6 includes a connecting plate 601, which is connected to a winch base 609 via a winch support plate 603. A winch shaft 606 is mounted on the winch base 609, and winch shaft covers 604 are installed at both ends of the winch shaft 606. A winch wire wheel 610, a straight tooth 611, and a winch shaft spike wheel 605 are sequentially mounted on the winch shaft 606. A winch cover 608 is installed on the outside of the straight tooth 611, and a spike wheel catch 607 cooperates with the winch shaft spike wheel 605 for positioning. The rope is wound around the winch wire. The winch is mounted on wheel 610, with a winch shaft 606 and a U-bolt 602 connected to both ends. This configuration, along with the winch structure and rope winding, allows for flexible adjustment of the equipment's position and stress state, effectively coping with different water flow impacts and ensuring stable equipment operation. Precise positioning and secure connections reduce equipment sway and deformation, lowering the risk of damage and extending service life. Simultaneously, it allows for rapid adjustment to adapt to different working conditions, improving installation and maintenance efficiency, thereby reducing labor and time costs and enhancing overall power generation efficiency and economic benefits.

[0085] In the preferred embodiment, in step 1, the motor support platform 102 and speed increaser platform 106 of the power generation system 1 are connected to the connecting plate 201 of the transmission system 2 via a hollow sleeve 104 and a connecting shaft 105, and the coaxiality error between the power generation system 1 and the transmission system 2 is ≤0.5mm. This configuration ensures the smoothness of power transmission between the power generation system 1 and the transmission system 2, reducing vibration and wear caused by coaxiality deviation. The combined structure of the hollow sleeve 104 and the connecting shaft 105 ensures connection strength while reducing overall weight, thus improving the system's operating efficiency and reliability.

[0086] In the preferred embodiment, in step 4, a preset water flow velocity range is established. When the energy conversion efficiency is lower than the set percentage, it is determined that the flow velocity exceeds the range, and the opening angle of the guide plate 405 is adjusted. This setting ensures that the water flow velocity is always within the optimal range, avoiding the impact of excessively fast or slow flow velocity on energy conversion efficiency. By real-time monitoring and automatic adjustment of the opening angle of the guide plate 405, the system can quickly respond to changes in flow velocity, maintain efficient and stable operation, and improve the overall energy utilization effect.

[0087] In summary, the rope-guided double-layer blade hydroelectric power generation device and method provided by this invention effectively solves a long-standing technical problem in the field of marine underwater power generation equipment. Addressing the issue that traditional fixed devices relying on rigid structures are prone to irreversible bending deformation, this invention employs a combined constraint structure of rope and winch shaft 606 to fix the power generation device 1. This flexible fastening method dynamically disperses the impact force of the water flow, significantly improving the device's bending resistance. Simultaneously, to address the challenge of water flow velocity fluctuations affecting power generation stability, this invention introduces a valve-type regulating device to achieve dynamic flow velocity control. Through the linkage between the rotatable adjustable blades and the water flow velocity sensor, the incoming water velocity is automatically maintained within the optimal range, ensuring the stability of power generation. Furthermore, addressing the low efficiency of traditional blade designs, this invention designs a vertically withdrawable double-layer staggered blade assembly, forming a "water flow relay capture" effect, which not only improves water energy utilization but also effectively reduces eddy current losses. In terms of technical implementation, this invention utilizes dynamic rope tension adjustment technology to control the main body bending deformation within 0.5mm during continuous operation for 3000 hours at a flow rate of 4m / s, extending the lifespan by more than 2 times and significantly enhancing the equipment's durability. Simultaneously, a double-layer vertically withdrawable blade structure was developed, which significantly improves water energy conversion efficiency compared to traditional designs and reduces the load intensity on a single blade, further enhancing the equipment's power generation efficiency and reliability. Ultimately, this invention constructs a three-dimensional technical system of "structural innovation + intelligent adjustment + energy efficiency optimization," achieving a synergistic breakthrough in equipment lifespan, power generation efficiency, and installation convenience. The installation time for a single setup is reduced to less than 2 hours, bringing a revolutionary change to the field of marine underwater power generation equipment.
