Description

Technical fields:

[0001] This invention relates to a retractable wave energy generation device based on a platform column. Background technology:

[0002] With the rapid development of the world economy, global energy demand has increased significantly. However, limited traditional energy sources such as oil and coal will be difficult to meet demand in the near future and will also lead to a series of environmental problems. The development and utilization of renewable energy has become more urgent and pressing. The ocean, which covers 71% of the Earth's surface, is a treasure trove of green energy, and wave energy is ubiquitous in the vast ocean and is considered one of the most promising ocean energy sources.

[0003] Wave energy boasts advantages such as large energy storage, high energy density, and minimal environmental impact, making it a promising solution to the global shortage of traditional energy sources and environmental pollution, thus attracting increasing attention. High wave energy levels are primarily concentrated in the deep sea, and among various wave energy devices, floating wave energy devices demonstrate broad application prospects due to their high conversion efficiency. However, the practical application of wave energy technology is still in its early stages, facing challenges such as high installation costs, maintenance difficulties, and difficulty in recovering investment costs. Currently, the main methods to address cost issues are developing wave energy device arrays or combining wave energy devices with other marine engineering equipment. The development of wave energy arrays is based on the development of individual wave energy devices. Given the immaturity of individual device research, array development is somewhat limited. Consequently, existing wave energy power generation devices cannot provide long-term, stable, and sustainable power supply, compromising power security and reliability, leading to significant inconvenience for platform operations and staff living quarters. Summary of the Invention:

[0004] This invention provides a retractable wave energy generation device based on a platform column. With a reasonable structural design, and through the coordinated action of multiple functional components and devices, it can provide long-term, stable, and sustainable power supply, ensuring the safety and reliability of the power supply. By combining the wave energy generation device with a semi-submersible drilling platform, it effectively utilizes the semi-submersible platform column structure, providing great convenience for power supply to platform operations and personnel living quarters. It is easy to install, update, and maintain, and features integration, miniaturization, and modular design with good engineering practicality. It can be widely applied to various application scenarios such as marine observation instruments, deep-sea cages, marine ranches, and marine platforms, making it suitable for widespread use and solving the problems existing in the prior art.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0006] A retractable wave energy power generation device based on platform columns is disclosed. The power generation device includes four platform columns. Each platform column has a retractable box installed in its interior through openings in the column. Each retractable box is equipped with a box drive motor, which is used to drive the retractable box to extend or retract. Each retractable box has a wave energy buoy power generation component installed on its outer side. When the buoy moves up and down under the action of waves, the wave energy buoy power generation component drives the rack connected above to drive the generator drive shaft to rotate and generate electricity.

[0007] The telescopic housing includes a first lead screw, four housings, a telescopic slide rail, a gear assembly, a rack plate, and a row of rollers. Each housing comprises a first, second, third, and fourth housing connected together. A housing drive motor is fixedly installed inside the platform column's internal compartment to provide power to the first lead screw, causing it to rotate and move the internally threaded first housing. Two rows of rollers are installed parallel to each other below the first housing, cooperating with the slide rail installed inside the platform column's compartment to allow the rollers to move linearly. Gears on both sides of the first housing mesh with the fixed rack plate inside the platform column's compartment and the rack plate of the second housing, respectively. Two rows of rack plates are installed on the inner sides of both sides of the first housing to mesh with the gears on both sides of the second housing. Two rows of rollers are installed parallel to each other below the second housing. A guide rail is installed above the bottom plate of the first housing to allow the rollers of the second housing to move linearly. When the housing drive motor drives the first housing in reciprocating motion, the second housing is simultaneously driven to reciprocate by the action of two sets of gears and racks.

[0008] The gears of the second housing mesh with the outer racks on both sides of the third housing, and the gears of the third housing mesh with the inner racks on both sides of the second housing. A roller frame and a row of rollers are installed at the bottom of the third housing, and a guide rail is installed at the bottom of the second housing to make the rollers move in a straight line. When the second housing is driven by the first housing to make reciprocating motion, the third housing is also driven by the gear and rack structure on the second housing to make reciprocating motion. At the same time, the fourth housing is driven by the gear and rack combination of the third housing in the same way. The wave energy float power generation component is installed inside the fourth housing.

[0009] The wave energy pontoon power generation assembly includes a generator and a pontoon deployment and recovery assembly. A second drive motor is installed on the upper part of the fourth housing. The second drive motor is used to provide power to the pontoon deployment and recovery assembly. A second lead screw is connected to the second drive motor and vertically connected to the bottom of the fourth housing to provide transmission and support. A generator bracket is hoisted and fixed on the lower connecting column of the second drive motor compartment. The generator bracket is used to support three generators and the pontoon outer frame. The generators and the pontoon outer frame are fixedly connected. A generator guide rail is provided on the generator bracket so that the generators and the pontoon outer frame can move longitudinally along the generator guide rail.

[0010] A sleeve is installed on the second lead screw below the generator bracket. The three sides of the sleeve are connected to the outer frame of the float by two connecting rods, so that the sleeve moves down or up to drive the connecting rods to push or retract the outer frame of the float and the generator. Three sets of gear reducers are installed on the second lead screw and connecting column between the second drive motor and the generator bracket. The gear reducers are used to drive the pull wire coil to rotate, so that the pull rope on the pull wire coil can be tightened or released from the barb bar.

[0011] The pontoon deployment and retrieval assembly includes a steel cable coil installed above the sleeve. The three sets of steel cables of the steel cable coil are respectively guided in three directions where the pontoon is located, and guided vertically downward via pulleys on the upper part of the generator frame. The ends of the steel cables are tied to the cable guide holes of the pontoon connecting frame for hoisting the pontoon, so that the pontoon is raised and lowered as the steel cable coil rotates and the steel cable pulleys move.

[0012] The pontoon includes a pontoon connecting frame and a lower pontoon. The pontoon connecting frame is fixed to the upper surface of the lower pontoon. The outer plates on both sides of the pontoon connecting frame cooperate with the guide rails of the pontoon outer frame to limit the movement direction of the pontoon to the vertical direction. A boss is provided on the pontoon connecting frame. The boss is used to abut against the barbs on the spike rod so that the spike rod moves up and down with the pontoon connecting frame. The top of the spike rod is connected to a rack. The rack drives the spur gear to rotate. The spur gear drives the transmission rod to rotate, which in turn drives the bevel gear to rotate, thereby rotating the generator drive shaft to generate electricity.

[0013] The second drive motor works in conjunction with the second lead screw to drive the release and recovery of the pontoon, the extension and retraction of the generator and the pontoon frame, and the release and tensioning of the spike.

[0014] The wave energy buoy power generation component is manufactured using materials resistant to seawater corrosion.

[0015] This invention employs the aforementioned structure, using a housing drive motor to extend or retract the housing. When the buoy moves up and down due to wave action via a wave energy buoy generator assembly, the buoy drives a rack connected above it, which in turn rotates the generator drive shaft to generate electricity. A second drive motor provides power to the buoy deployment and retrieval assembly. A second lead screw connected externally to the second drive motor is vertically connected to the bottom of the fourth housing for transmission and support. A gear reducer drives the pull wire coil to rotate, allowing the pull rope on the pull wire coil to tighten or release the barb. Three sets of steel cables from the steel cable coil are guided to the three locations of the buoy, and then guided vertically downwards via pulleys on the upper part of the generator frame. This design offers advantages of simplicity, practicality, safety, and reliability. Attached image description:

Detailed implementation method:

[0024] To clearly illustrate the technical features of this solution, the invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0025] like Figure 1-7 As shown, a retractable wave energy power generation device based on platform columns is disclosed. The power generation device includes four platform columns 1. Each platform column 1 has a retractable box installed in its interior through a column opening 2. Each retractable box is equipped with a box drive motor 7, which is used to drive the retractable box to extend or retract. Each retractable box has a wave energy buoy power generation component installed on its outer side. When the buoy moves up and down under the action of waves, the wave energy buoy power generation component drives the rack connected above to drive the generator drive shaft 39 to rotate and generate stable power.

[0026] The telescopic housing includes a first lead screw 8, four housings, a telescopic slide rail 9, a gear assembly 11, a rack plate 10, and a row of rollers 12 arranged in a coordinated manner. Each housing includes a first housing 3, a second housing 4, a third housing 5, and a fourth housing 6 that are joined together. A housing drive motor 7 is fixedly installed inside the platform column 1 to provide power to the first lead screw 8, causing it to rotate and drive the internally threaded first housing 3. Two rows of rollers 12 are installed parallel to each other below the first housing 3, cooperating with the slide rail installed inside the platform column 1. The linked rollers 12 move in a straight line; the gears on both sides of the first housing 3 mesh with the fixed rack plate in the platform column 1 and the rack plate of the second housing 4 respectively; two rows of rack plates are installed on the inner sides of both sides of the first housing 3 for meshing with the gears on both sides of the second housing 4; two linked rollers are installed in parallel below the second housing 4; a guide rail is installed above the bottom plate of the first housing 3 to make the rollers of the second housing 4 move in a straight line, so that when the housing drive motor 7 drives the first housing 3 to reciprocate, the second housing 4 is driven to reciprocate simultaneously by the action of the two sets of gears and racks.

[0027] The gears of the second housing 4 mesh with the outer racks on both sides of the third housing 5, and the gears of the third housing 5 mesh with the inner racks on both sides of the second housing 4. A roller frame and a row of rollers are installed at the bottom of the third housing 5, and a guide rail is installed at the bottom of the second housing 4 to make the rollers move in a straight line. When the second housing 4 is driven by the first housing 3 to make reciprocating motion, the third housing 5 is also driven by the gear and rack structure on the second housing 4 to make reciprocating motion. At the same time, the fourth housing 6 is driven by the gear and rack combination of the third housing 5 in the same way. The wave energy float power generation component is installed inside the fourth housing 6.

[0028] The wave energy pontoon power generation assembly includes a generator 17 and a pontoon deployment and recovery assembly. A second drive motor 14 is installed on the upper part of the fourth housing 6. The second drive motor 14 is used to provide power to the pontoon deployment and recovery assembly. A second lead screw 18 is connected to the second drive motor 14 and vertically connected to the bottom of the fourth housing 6 to play a transmission and support role. A generator bracket 15 is hoisted and fixed on the lower connecting column of the second drive motor 14. The generator bracket 15 is used to carry three generators 17 and the pontoon outer frame 19. The generators 17 and the pontoon outer frame 19 are fixedly connected. A generator guide rail 16 is provided on the generator bracket 15 so that the generators 17 and the pontoon outer frame 19 can move longitudinally along the generator guide rail 16.

[0029] A sleeve 23 is installed on the second lead screw 18 below the generator bracket 15. The three sides of the sleeve 23 are connected to the outer frame of the float 19 by two connecting rods, so that the sleeve 23 moves down or up to drive the connecting rod 20 to push or retract the outer frame of the float 19 and the generator 17. Three sets of gear reducers 24 are installed on the second lead screw 18 and the connecting column between the second drive motor 14 and the generator bracket 15. The gear reducers 24 are used to drive the pull coil 35 to rotate, so that the pull rope on the pull coil 35 can be tightened or released from the barb rod 31.

[0030] The pontoon deployment and retrieval assembly includes a steel cable coil 29 installed above the sleeve 23. The three sets of steel cables of the steel cable coil 29 are respectively guided in three directions where the pontoon 23 is located, and guided vertically downward via pulleys on the upper part of the generator frame. The end of the steel cable 28 is tied to the cable guide hole 38 of the pontoon connecting frame 21 for hoisting the pontoon, so that the pontoon is raised and lowered with the rotation of the steel cable coil 29 and the steel cable pulley 40.

[0031] The pontoon includes a pontoon connecting frame 21 and a lower pontoon 22. The pontoon connecting frame 21 is fixed to the upper surface of the lower pontoon 22. The outer plates on both sides of the pontoon connecting frame 21 cooperate with the outer frame guide rail 32 of the pontoon to limit the movement direction of the pontoon to the vertical direction. A boss 33 is provided on the pontoon connecting frame. The boss 33 is used to abut against the barb 31 on the barb 30 so that the barb 30 moves up and down with the pontoon connecting frame 21. The top of the barb 30 is connected to a rack. The rack drives the spur gear 36 to rotate. The spur gear 36 drives the transmission rod to rotate, so that the bevel gear 37 rotates accordingly, thereby causing the generator transmission shaft 39 to rotate to generate electricity.

[0032] The second drive motor 14 works in conjunction with the second lead screw 18 to drive the release and recovery of the pontoon, the extension and retraction of the generator 17 and the pontoon outer frame 19, and the release and tensioning of the spike 30.

[0033] The wave energy buoy power generation component is manufactured using materials resistant to seawater corrosion.

[0034] The working principle of a retractable wave energy generation device based on a platform column in this invention embodiment is as follows: Based on the coordinated action of multiple functional components and equipment, it can provide long-term, stable, and sustainable power supply, ensuring the safety and reliability of the power supply. By combining the wave energy generation device with a semi-submersible drilling platform, it effectively utilizes the semi-submersible platform column structure, providing great convenience for power supply to platform operations and personnel living quarters. It is easy to install, update, and maintain, and features integration, miniaturization, and modular design with good engineering practicality. It can be widely applied to various application scenarios such as marine observation instruments, deep-sea cages, marine ranches, and marine platforms, and is suitable for widespread use. The device mainly includes four retractable sections. The system comprises a retractable container, a container drive motor, a float deployment and recovery device, floats, and a generator. When the system needs to generate electricity, the container drive motor, in conjunction with a rack and pinion mechanism, pushes out the four containers one at a time. Then, the second drive motor, located in the fourth container, works with a sleeve connecting rod and a gear reducer to extend the three floats to their designated positions. As the floats move up and down due to wave action, the rack connected above the floats drives the generator drive shaft to rotate and generate electricity. In rough sea conditions, the system is recovered and placed in the platform column. When the system is recovered, the second drive motor reverses to retrieve the floats, generator, float outer frame, and other components into the fourth container. Subsequently, the first drive motor reverses to retrieve all the containers into the platform column.

[0035] The overall scheme mainly includes four platform columns 1. Each platform column 1 has a telescopic box installed in its interior through a column opening 2. Each telescopic box is equipped with a box drive motor 7, which is used to drive the telescopic box to be pushed out or retrieved. Each telescopic box is equipped with a wave energy buoy power generation component on its outer side. When the buoy moves up and down under the action of waves, the wave energy buoy power generation component is used to drive the rack connected above the buoy to drive the generator drive shaft 39 to rotate and generate stable power.

[0036] Preferably, the telescopic housing includes a first lead screw 8, four housings, a telescopic slide rail 9, a gear assembly 11, a rack plate 10, and a row of rollers 12 arranged in a coordinated manner. Each housing includes a first housing 3, a second housing 4, a third housing 5, and a fourth housing 6 connected together. A housing drive motor 7 is fixedly installed inside the platform column 1 to provide power to the first lead screw 8, causing the first lead screw 8 to rotate and drive the internally threaded first housing 3 to move. Two rows of rollers 12 are installed parallel to each other below the first housing 3, cooperating with the slide rails installed inside the platform column 1. The guide rail causes the row of rollers 12 to move in a straight line; the gears on both sides of the first housing 3 mesh with the fixed rack plate in the platform column 1 and the rack plate of the second housing 4 respectively. Two rows of rack plates are installed on the inner sides of both sides of the first housing 3 for meshing with the gears on both sides of the second housing 4; two rows of rollers are installed in parallel below the second housing 4. The guide rail is installed above the bottom plate of the first housing 3 to make the rollers of the second housing 4 move in a straight line, so that when the housing drive motor 7 drives the first housing 3 to reciprocate, the second housing 4 is driven to reciprocate simultaneously by the action of the two sets of gears and racks.

[0037] Furthermore, the gears of the second housing 4 mesh with the outer racks on both sides of the third housing 5, and the gears of the third housing 5 mesh with the inner racks on both sides of the second housing 4. A roller frame and a row of rollers are installed at the bottom of the third housing 5, and a guide rail is installed at the bottom of the second housing 4 to make the rollers move in a straight line. When the second housing 4 is driven by the first housing 3 to make reciprocating motion, the third housing 5 is also driven by the gear and rack structure on the second housing 4 to make reciprocating motion. At the same time, the fourth housing 6 is driven by the gear and rack combination of the third housing 5 in the same way. The wave energy buoy power generation component is installed inside the fourth housing 6, and the extension and retraction of the housing is controlled by the housing drive motor 7. When working, the device is pushed out to generate electricity using wave energy. The extension and retraction of the housing and the buoy increase the heave and roll damping of the platform, thereby improving the stability of the platform.

[0038] In harsh sea conditions, the device can be retrieved to protect it from damage. Multiple devices are symmetrically arranged within the four pillars of the platform, which ensures that the semi-submersible platform is subjected to uniform stress and maintains the stability of the drilling platform in harsh sea conditions. The device can adapt well to the complex and ever-changing marine environment and is also applicable to other semi-submersible platforms with multi-pillar symmetrical structures.

[0039] The two drive motors in this application only consume electrical energy during the release and retraction of the device. When the device is working, it does not need to provide additional energy. The box drive motor 7 drives the four boxes to release and retract simultaneously, the second drive motor 14 can simultaneously drive the release and retraction of the floats, the extension and retraction of the generator 17 and the float frame 19, and the release and tensioning of the barb 30 and barb 31, thus saving the device's own power consumption and production costs.

[0040] Preferably, the wave energy pontoon power generation assembly includes a generator 17 and a pontoon deployment and recovery assembly. A second drive motor 14 is installed on the upper part of the fourth housing 6. The second drive motor 14 is used to provide power to the pontoon deployment and recovery assembly. A second lead screw 18 is connected to the second drive motor 14 and vertically connected to the bottom of the fourth housing 6 to play a transmission and support role. A generator bracket 15 is hoisted and fixed to the lower connecting column of the second drive motor 14. The generator bracket 15 is used to support three generators 17 and the pontoon outer frame 19. The generators 17 and the pontoon outer frame 19 are fixedly connected. A generator guide rail 16 is provided on the generator bracket 15 so that the generators 17 and the pontoon outer frame 19 can move longitudinally along the generator guide rail 16 to ensure precise positioning.

[0041] Preferably, a sleeve 23 is installed on the second lead screw 18 below the generator bracket 15. The three sides of the sleeve 23 are respectively connected to the outer frame of the float 19 by two connecting rods, so that the sleeve 23 moves down or up to drive the connecting rods to push or retract the outer frame of the float 19 and the generator 17. Three sets of gear reducers 24 are installed on the second lead screw 18 and the connecting column between the second drive motor 14 and the generator bracket 15. The gear reducers 24 are used to drive the pull coil 35 to rotate, so that the pull rope on the pull coil 35 can be tightened or released from the barb rod 31.

[0042] During the deployment and retrieval of the float 23, it will be obstructed by the barb rod 31. Therefore, a barb rod retraction device needs to be installed. The device includes a gear reducer 24, a pull line 27, and a pull line coil 35. The pull line coil 35 is installed on the connecting column 25. When the second screw 18 rotates forward, the overall wave energy generator is released, and the gear reducer 24 rotates accordingly. The pull line coil 35 is driven by the gear reducer 24 to rotate forward and release the pull line 27. The pull line 27 relaxes and releases the barb rod 31. When the second screw 18 rotates in reverse, the overall wave energy generator is retracted, and the pull line coil 35 is driven by the gear reducer 24 to rotate in reverse and retract the pull line 27. The pull line 27 gradually tightens the barb rod 31 until it is tightly attached to the barb rod.

[0043] Preferably, the pontoon deployment and retrieval assembly includes a steel cable coil 29 installed above the sleeve 23. Three sets of steel cables from the steel cable coil 29 are guided in three directions relative to the pontoon 23, and guided vertically downwards via pulleys on the upper part of the generator frame. The ends of the steel cables 28 are attached to the cable guide holes 38 of the pontoon connecting frame 21 for hoisting the pontoon, allowing the pontoon to rise and fall with the rotation of the steel cable coil 29 and the steel cable pulleys 40. The pontoon includes a pontoon connecting frame 21 and a lower pontoon 22, with the pontoon connecting frame 21 fixed to the upper surface of the lower pontoon 22. The outer plates on both sides of the float connecting frame 21 cooperate with the float outer frame guide rail 32 to restrict the movement direction of the float to the vertical direction. The float connecting frame is provided with a boss 33, which is used to abut against the barb 31 on the barb 30 so that the barb 30 moves up and down with the float connecting frame 21. The top of the barb 30 is connected to a rack, which drives the spur gear 36 to rotate. The spur gear 36 drives the transmission rod to rotate, which causes the bevel gear 37 to rotate, thereby causing the generator transmission shaft 39 to rotate to generate electricity.

[0044] Guided downwards by the steel cable pulley 40, the coil and steel cable are installed at the cable guide hole 38 above the float connecting frame 21. The coil and steel cable serve to hoist the float connecting frame 21 and the lower float 22, which are fixedly connected. When the second drive motor 14 drives the second lead screw 18 to rotate forward, the steel cable coil 29 rotates simultaneously to release the steel cable 28, and the float connecting frame 21 and the lower float 22 are lowered to the designated working position. When the second drive motor 14 rotates in reverse, the steel cable coil 29 retracts the steel cable, and the float connecting frame 21 and the lower float 22 move upwards and are retracted into the fourth box 6.

[0045] When the wave level rises, the lower float 22 moves upward under buoyancy, and the float connecting frame 21, which is fixed to the lower float 22, moves upward simultaneously. The connecting frame boss 33 installed on the inner side of the connecting frame 21 abuts against the downward-facing barbed rod 31. The barbed rod 31 is symmetrically arranged on the barbed rod 30, thereby driving the barbed rod 30 to move upward. The other end of the barbed rod 30 is fixedly connected to the rack 26. The upward movement of the barbed rod 30 causes the rack 26 to move upward, and the rack 26 meshes with the spur gear 36, thereby driving the spur gear 36 to rotate. The rotation of the spur gear 36 drives the drive shaft to rotate, and the bevel gear 37 installed on one side of the drive shaft rotates with the drive shaft, ultimately driving the generator drive shaft 39 to rotate and generate electricity. When the wave level drops, the lower float 22 moves downward under its own weight, and the connecting frame boss 33 installed on the inner side of the connecting frame 21 abuts against the upward-facing barbed rod 31, pulling the barbed rod 30 and the rack 26 downward. This cycle repeats, driving the generator 17 to generate electricity.

[0046] In summary, the retractable wave energy generation device based on a platform column in this embodiment of the invention, through the coordinated action of multiple functional components and equipment, can provide long-term, stable, and sustainable power supply, ensuring the safety and reliability of the power supply. By combining the wave energy generation device with a semi-submersible drilling platform, it effectively utilizes the semi-submersible platform column structure, providing great convenience for power supply for platform operations and personnel living quarters. It is easy to install, update, and maintain, and features integration, miniaturization, and modular design with good engineering practicality. It can be widely applied to various application scenarios such as marine observation instruments, deep-sea cages, marine ranches, and marine platforms, and is suitable for widespread use. The device mainly includes four retractable sections. The system comprises a container, a container drive motor, a pontoon deployment and recovery device, pontoons, and a generator. When the system needs to generate electricity, the container drive motor, in conjunction with a rack and pinion mechanism, pushes out the four containers one at a time. Then, the second drive motor, located in the fourth container, works with a sleeve connecting rod and a gear reducer to extend the three pontoons to their designated positions. As the pontoons move up and down due to wave action, the rack connected above the pontoons drives the generator drive shaft to rotate and generate electricity. In rough sea conditions, the system is recovered and placed in the column. When the system is recovered, the second drive motor reverses to retrieve the pontoons, generator, pontoon outer frame, and other components into the fourth container. Subsequently, the first drive motor reverses to retrieve all the containers into the platform column.
