Description
A ship crane integrating a wind power generation system Technical Field
[0001] This application relates to the field of wind power generation technology, and in particular to a ship crane integrated with a wind power generation system. Background Technology
[0002] Traditional offshore wind power generation requires anchoring to the seabed, resulting in high installation costs and difficulty in relocation. Furthermore, fixed structures are difficult to adjust their angle according to wind direction, leading to low power generation efficiency. Ships rely on fuel-powered generators for electricity during ocean voyages, resulting in high carbon emissions and low utilization of renewable energy. However, with abundant offshore winds, wind turbines can be installed on ships to provide clean energy, thereby reducing carbon emissions.
[0003] Chinese patent CN119262201A discloses an offshore wind power generation vessel. Using the hull as its base, several crossbeams and vertical rods are arranged on both sides of the hull, allowing for a more flexible blade layout. The blades can be adjusted in angle or position according to changes in wind direction and speed, thereby maximizing wind energy capture efficiency and enhancing the adaptability and stability of the wind power generation vessel under different sea conditions and climates. The connection between the blades and the power generation unit efficiently captures abundant offshore wind energy resources and converts them into electrical energy. Simultaneously, the power generation unit is directly connected to the hull's drive unit, achieving instant energy conversion and utilization. This integrated design not only simplifies the energy transmission process and reduces energy loss but also makes the entire system more compact and efficient, providing reliable guarantees for the vessel's autonomous navigation and power supply.
[0004] In the existing technology, installing fixed wind turbines on the deck or hull of a ship requires separate installation of wind power generation equipment. Because the wind power generation equipment is too large, it occupies the working area of the ship and is not suitable for non-dedicated wind power generation vessels, which affects the loading and unloading of cargo.

[0013] The present application will be further described in detail below with reference to Figures 1-8.
[0014] This application discloses a ship crane integrated with a wind power generation system.
[0015] Referring to Figures 1 and 8, a ship crane integrating a wind power generation system includes a crane body 1, which includes a base 11. A bracket 12 is rotatably mounted on the base 11, and the bottom of the bracket 12 is rotatably connected to the base 11 via a slewing bearing. A rotating main boom 13 is rotatably mounted inside the bracket 12, and a wind power generation component 2 is mounted on the free end of the rotating main boom 13. A counterweight 14 and a main controller 15 are provided on the side of the rotating main boom 13 away from the wind power generation component 2. The wind power generation component 2 includes a rotating rod 21 and a rotating seat 22, wherein the rotating seat 22 is used to mount blades 23 and is fixed to the end of the rotating rod 21. The blades 23 can... The rotating rod 21 is stored in the storage compartment 131 of the rotating main arm 13. The end of the rotating rod 21 away from the rotating seat 22 is connected to the generator through a gearbox. The rotating main arm 13 is equipped with multiple sets of bearing seats for mounting the rotating shaft. The wind direction tracking system 3 is located on the top of the support 12 and includes a sensor 31 and a controller 32. The bottom support 12 of the sensor 31 is rotatably connected to the support 12 through a slewing bearing. The two ends of the sensor 31 are wind speed sensor 311 and wind direction sensor 312. The safety control module includes a strain sensor 31 installed at the root of the blade 23. Both the strain sensor 31 and the controller 32 are signal connected to the main controller 15. During operation, the base 11 supports the bracket 12 via a slewing bearing, enabling horizontal rotation. The rotating main boom 13 within the bracket 12 can be flexibly adjusted in elevation using a hydraulic cylinder on the bracket 12. The wind turbine generator 2 at its free end is mounted on a rotating seat 22 at the end of the rotating rod 21, with blades 23 installed. When not in operation, the blades 23 can be stored in the storage compartment 131 of the rotating main boom 13. In operation, the rotation of the blades 23 drives the rotating seat and rotating rod 21 to rotate. The rotating rod 21 is connected to the generator via a gearbox. The gearbox converts the low-speed, high-torque mechanical energy on the rotating rod 21 into the high-speed, low-torque mechanical energy required by the generator, thereby achieving efficient power generation. The wind direction tracking system 3 at the top of the support 12 monitors environmental parameters in real time through wind speed sensor 311 and wind direction sensor 312. The bottom of sensor 31 rotates flexibly with the wind direction via a slewing bearing. The controller 32 transmits the sensed data to the main controller 15. The main controller 15, in conjunction with the counterweight 14 on the other side of the rotating main arm 13 to ensure structural balance, adjusts the steering angle of the support 12 and the rotating main arm 13 according to the wind direction and wind speed information, so that the blade 23 always maintains the optimal windward posture, efficiently capturing wind energy and converting it into electrical energy through the generator. At the same time, the strain sensor 31 at the root of the blade 23 monitors the stress state of the blade 23 in real time. Once stress exceeding the safety threshold is detected, the signal is immediately fed back to the main controller 15. The main controller 15 quickly activates the safety control mechanism, which can adjust the angle of the blade 23 or retract it into the storage cavity, ensuring the safe and stable operation of the entire system under complex sea conditions.
[0016] Referring to Figures 1 and 8, the blade 23 is fixed to the rotating seat 22 by a hydraulic pin 221. The hydraulic pin 221 is installed inside the rotating seat 22 and is driven by a linkage component 222 inside the rotating seat 22. The end of the blade 23 is provided with a positioning hole 231 that matches the hydraulic pin 221. The blade 23 is hinged to the rotating seat 22 by an integrally formed mounting block 232 at its root. Both ends of the mounting block 232 are rotatably connected to the adjusting bearing seats arranged in a circumferential array on the rotating seat 22. The rotating seat 22 has an integrally formed annular frame 223 at the center of the bearing seats. The annular frame 223 has a circumferential array of through holes 2231 for the hydraulic pin 221 to move. The linkage component 222 can drive the hydraulic pin 221 to move within the through holes 2231 and engage with the positioning hole 231 on the mounting block 232. The outer diameter of the through holes 2231 decreases from the outside to the inside on the annular frame 223, and the outer diameter of the hydraulic pin 221 matches the through holes 2231. The linkage component 222 includes a locking block 2221, which is ellipsably mounted in the top groove of the rotating seat 22. The locking block 2221 includes an inverted cone-shaped body 2222 at the top and a cylinder 2223 at the bottom. The bottom surface of the cylinder 2223 has a circumferential array of several sets of drive rods 2224, which penetrate the bottom surface of the groove of the rotating seat 22. The bottom of the drive rod 2224 is integrally formed with a horizontal plate 2225 that is horizontal to the bottom surface of the rotating seat 22. The free end of the rotating main arm 13 is also equipped with a power component 24 that drives the linkage component 222 to move up and down within the rotating seat 22. The power component 24 includes a locking mechanism 241 that drives the linkage component 222 to descend and an unlocking mechanism 242 that drives the linkage component 222 to rise. Both the locking mechanism 241 and the driving mechanism are mounted at the end of the rotating main arm 13, and the horizontal plate 2225 can rotate between the locking mechanism 241 and the unlocking mechanism 242. The locking mechanism 241 includes a locking hydraulic cylinder 2411 and an L-shaped output rod 2412 at its output end. A first annular sleeve 2413 is fixed to the end of the L-shaped output rod 2412, and the bottom of the first annular sleeve 2413 is in contact with the top surface of the horizontal plate 2225. The unlocking mechanism 242 includes an unlocking hydraulic cylinder 2421 and an output rod 2422 at its output end. A second annular sleeve 2423 is fixed to the end of the output rod 2422, and the second annular sleeve 2423 is in contact with the bottom of the horizontal plate 2225 of the drive rod 2224. Several sets of corresponding first electromagnets 243 are arranged in a circular array on the bottom surface of the first annular sleeve 2413 and the top surface of the second annular sleeve 2423. The positions of the first electromagnets 243 correspond to the positions adjacent to the storage compartments. The top and bottom surfaces of the horizontal plate 2225 are provided with second electromagnets 2226 corresponding to the first electromagnets 243.During operation, the mounting block 232 at the root of the blade 23 is hinged to the rotating seat 22 via an adjusting bearing seat. The annular frame 223 at the center of the rotating seat 22 has a circular array of through holes 2231 with an outer diameter decreasing from the outside to the inside. The hydraulic pin 221 is fitted into the through hole 2231. When it is necessary to fix the blade 23, the blade 23 is first rotated to a position perpendicular to the rotating main arm 13. Then, the locking hydraulic cylinder 2411 of the locking mechanism 241 drives the L-shaped output rod 2412 to descend. The first annular sleeve 2413 at its end fits against the top surface of the horizontal plate 2225, driving the locking block 2221 to descend. The driving rod 2224 at the bottom of the locking block 2221 pushes the hydraulic pin 221 to move inward along the through hole 2231, accurately inserting it into the positioning hole 231 of the mounting block 232 to complete the locking. During unlocking, the blades 23 on the rotating seat must first be aligned with the grooves on the rotating main arm 13. The unlocking hydraulic cylinder 2421 of the unlocking mechanism 242 drives the output rod 2422 to rise, and the second annular sleeve 2423 lifts the horizontal plate 2225, cooperating with the first annular sleeve 2413 to clamp the horizontal plate 2225. At this time, the first electromagnet 243 on the first annular sleeve 2413 and the second annular sleeve 2423 is energized, and the second electromagnet 2226 on the horizontal plate 2225 is simultaneously energized, realizing the adsorption and fixation between the first electromagnet 243 and the second electromagnet 2226. During the process of the unlocking hydraulic cylinder 2421 and the locking hydraulic cylinder simultaneously driving the horizontal plate 2225 to rise, the locking block 2221 rises and drives the drive rod 2224 to move upward. At this time, the locking block 2221 releases its action on the hydraulic pin 221. Under the action of the spring in the positioning hole 231, the hydraulic pin 221 retracts outward along the through hole 2231, releasing the constraint on the mounting block 232. The blade 23 can rotate around the bearing seat and be stored in the storage compartment 131 of the rotating main arm 13. The entire process is achieved by the hydraulic drive of the power component 24 and the cooperation of the electromagnet to achieve stable locking and releasing.
[0017] Referring to Figures 1 and 8, a hydraulic cylinder assembly 16 is provided inside the storage cavity. The hydraulic cylinder assembly 16 is located inside the blade 23. A clamping frame is installed at the output end of the hydraulic cylinder assembly 16. The opening of the clamping frame is adapted to the blade 23. A hydraulic clamping cylinder 171 is installed at the opening of the clamping frame. The output rod 2422 of the hydraulic clamping cylinder 171 can restrict the blade 23 within the clamping frame. The hydraulic cylinder assembly 16 includes a first hydraulic cylinder 161 that drives the positioning frame 17 and a second hydraulic cylinder 162 that drives the first hydraulic cylinder 161 to rotate. The blade 23 is stably placed in the storage compartment 131 in cooperation with the positioning frame 17. A cover 18 is provided at the opening of the storage compartment 131. A third hydraulic cylinder 181 that drives the opening and closing of the cover 18 is provided on the inner side of the cover 18. The third hydraulic cylinder 181 is located on the side of the storage compartment away from the rotating seat 22. When the blade 23 is retracted, the third hydraulic cylinder 181 at the opening of the storage compartment 131 drives the cover 18 to open. Subsequently, the hydraulic cylinder group 16 is activated. Specifically, the second hydraulic cylinder 162 drives the first hydraulic cylinder 161 to rotate to a suitable angle. The first hydraulic cylinder 161 pushes the clamping frame to extend towards the blade 23. After the opening of the clamping frame is adapted to the blade 23, the output rod 2422 of the hydraulic clamping cylinder 171 at the opening extends until the output rod 2422 of the hydraulic clamping cylinder 171 engages with the through hole 2231 on the other side of the opening, firmly securing the blade 23 within the clamping frame. Then, the first hydraulic cylinder 161 retracts, moving the blade 23 into the storage compartment 131. The second hydraulic cylinder 162 adjusts the angle to ensure that the blade 23 precisely engages with the positioning frame 17 for stable placement. Finally, the third hydraulic cylinder 181 drives the cover 18 to close, completing the retraction. When the blade 23 is released, the process is reversed. The third hydraulic cylinder 181 opens the hatch 18, the hydraulic clamping cylinder 171 retracts the output rod 2422 to release the constraint, and the first hydraulic cylinder 161 and the second hydraulic cylinder 162 work together to send the blade 23 out of the storage compartment 131 so that it can start working.
[0018] Referring to Figures 1 and 8, the wind speed sensor 311 is a propeller-type sensor 31, and the wind direction sensor 312 uses a wind vane to sense the wind direction. A Gray code disk is located at the bottom of the wind vane. The propeller-type sensor 31 and the Gray code disk are connected to the controller 32 via signals. When the wind direction tracking system 3 is working, the propeller-type wind speed sensor 311 senses the sea wind force through its propeller structure. When the airflow acts on the propeller, the propeller rotates at different speeds depending on the wind speed. Its internal components convert the rotation speed signal into an electrical signal and transmit it to the controller 32 in real time, providing data support for subsequent judgment of wind speed magnitude. Meanwhile, the wind vane of the wind direction sensor 312 always points in the direction of the wind under the action of the wind force. The Gray code disk connected to the bottom of the wind vane rotates synchronously with the wind vane. The Gray code disk converts the rotation angle into the corresponding Gray code electrical signal through its own encoding structure. This signal is also transmitted to the controller 32 in real time. After receiving the wind speed signal from the propeller sensor 31 and the wind direction signal from the Gray code disk, the controller 32 integrates and analyzes the two types of data to provide accurate wind direction and wind speed basis for subsequent adjustment of the bracket 12, rotation of the main arm 13 and blade 23 angles to achieve the best windward posture.
[0019] Working Principle: First, the wind speed sensor 311 and wind direction sensor 312 of the wind direction tracking system 3 at the top of the support 12 monitor real-time wind conditions. Sensor 31 transmits data to the controller 32, which then feeds it back to the main controller 15. The main controller 15 adjusts the orientation and angle of the rotating main arm 13 and the wind power generation component 2 based on the wind conditions, controlling the slewing bearing between the base 11 and the support 12, and the rotation structure between the support 12 and the rotating main arm 13, to maximize wind energy capture. When the wind power generation component 2 is working, the blades 23 unfold and connect to the rotating rod 21 through the rotating seat 22. The blades 23 rotate under wind force, which is transmitted to the gearbox via the rotating rod 21 to drive the generator to generate electricity. During operation, the strain sensor 31 at the root of the blades 23 monitors the stress in real time to ensure safe operation. When the blade 23 needs to be stored, the hydraulic cylinder group 16 inside the rotating main boom 13 drives the clamping frame to move, cooperating with the hydraulic clamping cylinder 171 to fix the blade 23. At the same time, the unlocking mechanism 242 of the power component 24 drives the linkage component 222 to rise, so that the hydraulic pin 221 exits from the positioning hole 231 of the blade 23, and the blade 23 can be folded into the storage compartment 131 of the rotating main boom 13. Finally, the third hydraulic cylinder 181 drives the hatch cover 18 to close. When unfolding, the operation is reversed. The locking mechanism 241 drives the linkage component 222 to descend, so that the hydraulic pin 221 inserts into the positioning hole 231 to fix the blade 23. Throughout the process, the counterweight 14 balances the center of gravity of the crane, and the safety control module is connected to the main controller 15 through the strain sensor 31 to monitor and ensure the safe and stable operation of the system in real time.
[0020] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
