Description

Technical Field

[0001] The invention relates to the technical field of wind power generation, and in particular to offshore wind power generation equipment capable of resisting strong winds. Background Art

[0002] Wind energy is a clean, renewable green energy with high development efficiency, good economy, large-scale development conditions and commercial prospects. With the development of science and technology, wind power generation technology has made rapid progress. With the increasing number of land wind farms, the development of wind farms has gradually shifted to the sea.

[0003] The patent with the patent announcement number CN221823957U discloses an offshore wind power generation device resistant to strong winds, including a nacelle, a mounting shell fixedly arranged on the front of the nacelle, a T-shaped ring arranged inside the mounting shell, a U-shaped shell fixedly arranged on the inner wall of the mounting shell, two groups of pistons penetrating the inner wall of the U-shaped shell, and an extrusion sheet fixedly arranged on one end of the piston. The patent is equipped with a T-shaped ring and an extrusion sheet. When a strong wind occurs and the blades drive the mounting hub to rotate rapidly, the operation of the air pressure pump will transmit air pressure into the U-shaped shell through the air inlet. The air pressure can push the piston to make the extrusion sheets on both sides squeeze the rotating T-shaped ring, thereby achieving a stable deceleration effect on the rotating mounting hub and blades, and effectively solving the technical problem that when extremely strong winds appear head-on at sea, the fan blades and the inside of the equipment are easily damaged due to excessive rotation speed.

[0004] However, the device still has some shortcomings: the device can prevent extremely strong winds from causing damage to power generation equipment, but the blades of the device are facing the wind, which may easily cause the blades to gradually deform toward the tower during the process of facing the wind. As the wind force continues to increase, the bending amplitude of the blades continues to increase, making it easy for the blades to contact and collide with the tower, easily causing damage to the blades and the tower. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides an offshore wind power generation equipment that is resistant to strong winds, and solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an offshore wind power generation device resistant to strong winds, comprising a device body, a mounting assembly is arranged on the top of the device body, a rotating shaft is arranged on the left side of the mounting assembly, a plurality of connecting shafts are arranged at equal distances on the outer wall of the rotating shaft, and blades are fixedly installed on the side of the connecting shafts away from the rotating shaft; An anti-collision device is arranged below the device body, an anti-resonance device is arranged inside the anti-collision device, and an anti-corrosion device is arranged inside the anti-resonance device; The anti-collision device includes a tower seat, which is arranged on the right side below the device body, and a sleeve connecting column is penetrated and rotatably installed inside the tower seat, a disc is fixedly installed on the top of the sleeve connecting column, the bottom of the disc is in contact with the top of the tower seat, and a long bracket is fixedly installed on the left side of the outer wall of the disc, and two floating tower bases are symmetrically arranged on the left side of the tower seat, and short brackets are fixedly installed on the top of the two floating tower bases, and a stabilizing frame is fixedly installed between the right side of the two floating tower bases and the left side of the outer wall of the sleeve connecting column, a fixing frame is fixedly installed on the outer wall of the two floating tower bases close to the device body, a floating ball assembly is fixedly installed on the bottom of the two floating tower bases, a floating assembly is arranged on the left side of the floating tower base, and a circular frame is hinged on the left side of the outer wall of the floating tower base.

[0007] According to the above technical scheme, the top of the long bracket is fixedly installed on the right side of the outer wall of the device body, and the tops of the two short brackets are respectively fixedly installed on the front and back sides of the outer wall of the device body. A torsion spring is arranged between the circular frame and the floating tower base. The bottom of the circular frame is hinged on the top of the floating assembly, and the tower base is fixedly installed on the offshore base. At this time, the sleeve connecting column is rotatably installed inside the tower base. The direction adjustment during installation ensures that the blades are always facing away from the wind. When the wind direction changes, the force wind direction of the blades and the installation assembly is changed synchronously. At this time, the device body drives the short bracket and the floating tower base to generate a rotational force with the tower base as the center. When the floating tower base and the short bracket revolve, they drive the stabilizing frame and the fixed frame to move synchronously. At this time, the stabilizing frame drives the sleeve connecting column to rotate synchronously along the tower base. At the same time, the sleeve connecting column drives the disc to rotate, and the disc drives the long bracket to rotate synchronously, thereby realizing the blade with the tower base as the center. The blades and other components rotate synchronously under the influence of the yaw wind, that is, there is no need for yaw software to detect the wind direction for azimuth adjustment; in the process of the blades being subjected to back force, the thrust of the wind is converted into thrust through the long bracket through its own tilted design. As the wind force continues to increase, the distance between the blades and components such as the installation components gradually becomes farther. At the same time, the downward pressure generated by the wind on the floating tower base continues to increase. The floating tower base will drive the buoy assembly to move downward in the sea in a slightly inclined posture. At the same time, the floating tower base drives the circular frame to move synchronously, and the circular frame drives the floating assembly to move synchronously. The floating assembly causes the hinge between itself and the circular frame to start rotating through the buoyancy between itself and the sea surface. At this time, the floating assembly floats away from the floating tower base under the pressure of the circular frame. At the same time, as the downward pressure of the floating tower base gradually increases, the buoyancy generated by the floating ball assembly and the floating assembly continues to increase, thereby pushing the floating tower base to reset.

[0008] According to the above technical solution, the anti-resonance device includes a fixed plate, a friction roller, a transverse plate, a rotating rod, a transmission roller and some spoilers. The right side of the fixed plate is fixedly installed on the left side of the outer wall of the tower base, the top of the friction roller is rotatably installed on the bottom of the left end of the fixed plate, both sides of the transverse plate are fixedly installed on the side of the stabilizing frame close to the device body, the outer wall of the rotating rod passes through and is rotatably installed inside the transverse plate, the bottom of the transmission roller is fixedly installed on the top of the rotating rod, and several of the spoilers are fixedly installed on the outer wall of the bottom end of the rotating rod.

[0009] According to the above technical solution, a reciprocating spiral groove is provided on the outer wall of the rotating rod, the outer wall of the transmission roller is in contact with the friction roller, and a plurality of spoilers are equidistantly distributed on the outer wall of the bottom end of the rotating rod, the tower seat limits the fixed plate, and the fixed plate limits the friction roller. When the stabilizing frame revolves around the tower seat as the center, it drives the cross plate to revolve, and when the cross plate revolves, it drives the rotating rod to revolve, and the rotating rod drives the transmission roller to contact the outer wall of the friction roller to generate friction. At this time, the transmission roller drives the rotating rod to start rotating along the inside of the cross plate through the friction force, and the rotating rod drives the spoiler to start rotating, so that the spoiler can rotate during the revolution.

[0010] According to the above technical scheme, the anti-resonance device also includes a sliding ring, an inclined plate, a bearing plate and a wave plate. The sliding ring passes through the inside and is movably installed on the outer wall of the reciprocating spiral groove of the rotating rod. The top of the inclined plate is fixedly installed on the left side of the outer wall of the sliding ring, and the bottom of the bearing plate is fixedly installed on the bottom of the inner wall of the stabilizing frame. The outer wall of the wave plate passes through and is slidably installed inside the bearing plate, and the right side of the wave plate is fixedly installed on the bottom of the inclined plate. When the rotating rod rotates, the reciprocating spiral groove on its outer wall restricts the built-in block of the sliding ring, so that the sliding ring is driven by the reciprocating spiral groove to slide downward and reset along the outer wall of the rotating rod, and the sliding ring drives the inclined plate to move synchronously, and the inclined plate pulls the wave plate to slide reciprocatingly downward and reset along the inside of the bearing plate.

[0011] According to the above technical scheme, the anti-corrosion device includes an L-shaped plate, a pressure plate and a rejection frame. The top of the L-shaped plate is fixedly installed on the outer wall of the sliding ring near one end of the rotating rod. The pressure plate passes through the inside and is slidably installed on the outer wall of the rotating rod. The top of the pressure plate is fixedly connected to the bottom of the L-shaped plate. The outer wall of the rejection frame is slidably installed on the surface of the spoiler through a spring. The top of the rejection frame contacts the bottom of the pressure plate. The sliding ring moves downward and resets, driving the L-shaped plate to move synchronously. The L-shaped plate drives the pressure plate to slide synchronously along the outer wall of the rotating rod. When the pressure plate moves downward, it will contact the top of the rejection frame and exert downward pressure on the rejection frame. At this time, the rejection frame will slide downward along the outer wall of the spoiler, and then the rejection frame will reset itself through the spring elastic force, and so on.

[0012] According to the above technical solution, the anti-corrosion device also includes a number of rotating wheels, a reciprocating screw, a sliding plate and a through rod. The several rotating wheels are symmetrically and rotatably installed inside the rejection frame. Both ends of the reciprocating screw are fixedly installed on the side of the rotating wheel close to the center of the rejection frame. The sliding plate penetrates inside and is movably installed on the outer wall of the reciprocating screw. The outer wall of the through rod penetrates and is fixedly installed inside the sliding plate.

[0013] According to the above technical solution, the outer walls of several of the rotating wheels are in contact with the outer wall of the spoiler, the bottom of the sliding plate is in contact with the bottom of the inner wall of the rejection frame, and the outer wall of the sliding plate is in contact with the surface of the spoiler. When the rejection frame slides downward along the outer wall of the spoiler, it drives the rotating wheel to move synchronously and rub along the outer wall of the spoiler. The rotating wheel begins to rotate inside the rejection frame through friction and drives the reciprocating screw to rotate. The reciprocating screw limits the built-in block of the sliding plate through the reciprocating spiral groove on its own outer wall, and the built-in block of the sliding plate continuously contacts the inner wall of the reciprocating spiral groove, so that the sliding plate can slide and reset along the outer wall of the reciprocating screw away from the rotating rod. The sliding plates achieve synchronous sliding through the limiting of the through rod, and the sliding plates continuously scrape the surface of the spoiler during the reciprocating sliding and resetting process.

[0014] The present invention provides an offshore wind power generation device that is resistant to strong winds. It has the following beneficial effects: (1) The present invention adopts the arrangement of an anti-collision device, and cooperates with a tower base, a sleeve connecting column, a disc, a long bracket, a floating tower base, a short bracket, a stabilizing frame, a fixing frame, a floating ball assembly, a floating assembly and a circular frame to achieve that when the wind direction is offset, the blades can automatically adjust their own orientation, so that the blades are always stressed on the back and face the strong wind at sea, thereby ensuring an efficient and stable power generation process. At the same time, when the blades are stressed in the back, they will bend and deform in the direction away from the installation assembly, which is different from the traditional forward stress that is easy to collide with the tower base and cause damage, thereby improving the safety of the power generation process; at the same time, under the promotion of the circular frame, the buoyancy support range of the floating assembly on the floating tower base is effectively increased, and the floating assembly cooperates with the floating ball assembly to increase the floating tower base's resistance to wind force, thereby ensuring that the floating power generation equipment will not be damaged or broken under the attack of a typhoon, and achieving a continuous, stable and efficient power generation effect without stopping.

[0015] (2) The present invention sets an anti-resonance device, and cooperates with a stabilizing frame, a fixed plate, a friction roller, a cross plate, a rotating rod, a transmission roller, a spoiler, a sliding ring, an inclined plate, a bearing plate and a wave plate. The spoiler interferes with the regular vibration caused by the impact of seawater on the tower base or the floating tower base, thereby avoiding the resonance of the tower base and the floating tower base with the impact of seawater, which leads to changes in their own mechanics, thereby generating cracks and causing the risk of seawater intrusion and collapse, thereby extending the service life of the entire equipment to a certain extent; at the same time, the wave surface of the wave plate is used to enhance the disturbance effect on the seawater within the range close to the float assembly, so as to cause the sea surface around the float assembly to fluctuate, thereby increasing the buoyancy flux, that is, enhancing the jacking effect of the float assembly on the floating tower base, and further accelerating the reset speed and wind resistance of the floating tower base on the original basis.

[0016] (3) The present invention sets an anti-corrosion device, and cooperates with a sliding ring, an L-shaped plate, a pressure plate, a rejection frame, a rotating wheel, a reciprocating screw, a sliding plate and a through rod. During the revolution and rotation of the spoiler, the impact frequency of the seawater is further disturbed by the reciprocating sliding of the rejection frame, thereby improving the interference effect of the spoiler on the regular impact of seawater on the original basis and reducing the probability of resonance. At the same time, the sliding plate is used to timely remove parasites such as barnacles attached to the surface of the spoiler, thereby preventing the rapid reproduction of parasites such as barnacles and aggravating the erosion of the spoiler, avoiding the accelerated corrosion rate of the spoiler and reducing the interference effect on the seawater. At the same time, the sliding plate effectively increases the lateral interference force of the rejection frame, thereby effectively improving the auxiliary effect of the rejection frame on the spoiler.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figure 1-Figure 8 One embodiment of the present invention is: an offshore wind power generation device resistant to strong winds, comprising a device body 1, a mounting assembly 2 is arranged on the top of the device body 1, a rotating shaft 21 is arranged on the left side of the mounting assembly 2, a plurality of connecting shafts 3 are arranged at equal distances on the outer wall of the rotating shaft 21, and blades 31 are fixedly installed on the side of the connecting shafts 3 away from the rotating shaft 21; An anti-collision device 4 is arranged below the device body 1, an anti-resonance device 5 is arranged inside the anti-collision device 4, and an anti-corrosion device 6 is arranged inside the anti-resonance device 5; The anti-collision device 4 includes a tower base 41, which is arranged on the right side below the device body 1. A sleeve connecting column 42 is penetrated and rotatably installed inside the tower base 41. A disc 43 is fixedly installed on the top of the sleeve connecting column 42, and the bottom of the disc 43 contacts the top of the tower base 41. A long bracket 44 is fixedly installed on the left side of the outer wall of the disc 43. Two floating tower bases 45 are symmetrically arranged on the left side of the tower base 41. Short brackets 46 are fixedly installed on the top of the two floating tower bases 45. Stabilizing frames 47 are fixedly installed between the right sides of the two floating tower bases 45 and the left side of the outer wall of the sleeve connecting column 42. Fixed frames 48 are fixedly installed on the outer walls of the two floating tower bases 45 close to the device body 1. Floating ball assemblies 49 are fixedly installed on the bottoms of the two floating tower bases 45. A floating assembly 410 is arranged on the left side of the floating tower base 45, and a circular frame 411 is hinged on the left side of the outer wall of the floating tower base 45.

[0021] The top of the long bracket 44 is fixedly mounted on the right side of the outer wall of the device body 1, and the tops of the two short brackets 46 are respectively fixedly mounted on the front and back sides of the outer wall of the device body 1. A torsion spring is arranged between the circular frame 411 and the floating tower base 45, and the bottom of the circular frame 411 is hinged on the top of the floating component 410. Through the above cooperation, the blade 31 can automatically adjust its own orientation when the wind direction is offset, so that the blade 31 is always stressed on the back and faces the strong wind at sea, ensuring an efficient and stable power generation process. At the same time, the blade 31 is subjected to back force and bends and deforms in a direction away from the mounting component 2, which is different from the traditional forward force, which is easy to collide with the tower base 41 and other components to cause damage, thereby improving the safety of the power generation process; through the above cooperation, the buoyancy support range of the floating component 410 on the floating tower base 45 is effectively increased under the promotion of the circular frame 411, and the floating component 410 cooperates with the floating ball component 49 to increase the wind resistance effect of the floating tower base 45, ensuring that the floating power generation equipment will not be damaged or broken under the attack of a typhoon, and achieving a continuous, stable and efficient power generation effect without stopping.

[0022] When in use, the tower base 41 is fixedly installed on the offshore base, and the sleeve connecting column 42 is rotatably installed inside the tower base 41. The direction adjustment during installation ensures that the blade 31 is always facing away from the wind. When the wind direction changes, the wind direction of the blade 31 and the installation component 2 is changed synchronously. At this time, the device body 1 drives the short bracket 46 and the floating tower base 45 to generate a rotational force with the tower base 41 as the center. When the floating tower base 45 and the short bracket 46 revolve, they drive the stabilizing frame 47 and the fixed frame 48 to move synchronously. At this time, the stabilizing frame 47 drives the sleeve connecting column 42 to rotate synchronously along the tower base 41, and at the same time, the sleeve connecting column 42 drives the disc 43 The disc 43 drives the long bracket 44 to rotate synchronously, thereby realizing the synchronous rotation of the blades 31 and other components with the tower base 41 as the center under the influence of the yaw wind force, that is, there is no need for yaw software to detect the wind direction for azimuth adjustment. Through the above cooperation, the blades 31 can automatically adjust their own azimuth when the wind direction deviates, so that the blades 31 are always stressed at the back and face the strong wind at sea, ensuring an efficient and stable power generation process. At the same time, the blades 31 will bend and deform in the direction away from the installation component 2 when stressed in the back, which is different from the traditional forward force that is easy to collide with the tower base 41 and other components and cause damage, thereby improving the safety of the power generation process; In the process of the blade 31 being subjected to the force in the reverse direction, the long bracket 44 converts the thrust of the wind into thrust through its own inclined design. As the wind force continues to increase, the distance between the blade 31 and the installation component 2 and other components gradually becomes farther. At the same time, the downward pressure generated by the wind on the floating tower base 45 continues to increase. The floating tower base 45 will drive the buoyancy ball assembly 49 to move downward in the sea in a slightly inclined posture. At the same time, the floating tower base 45 drives the circular frame 411 to move synchronously, and the circular frame 411 drives the floating assembly 410 to move synchronously. The floating assembly 410 causes the hinge between itself and the circular frame 411 to start rotating through the buoyancy between itself and the sea surface. At this time, the floating Under the pressure of the circular frame 411, the component 410 floats away from the floating tower base 45. At the same time, as the downward pressure of the floating tower base 45 gradually increases, the buoyancy generated by the float component 49 and the floating component 410 continues to increase, thereby pushing the floating tower base 45 to reset. Through the above cooperation, the buoyancy support range of the floating component 410 on the floating tower base 45 is effectively increased under the push of the circular frame 411. The floating component 410 cooperates with the float component 49 to increase the floating tower base 45's resistance to wind force, ensuring that the floating power generation equipment will not be damaged or broken during a typhoon, and achieving continuous, stable and efficient power generation without stopping.

[0023] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-resonance device 5; The anti-resonance device 5 includes a fixed plate 51, a friction roller 52, a cross plate 53, a rotating rod 54, a transmission roller 55 and an interference flow plate 56. The right side of the fixed plate 51 is fixedly installed on the left side of the outer wall of the tower base 41, the top of the friction roller 52 is rotatably installed on the bottom of the left end of the fixed plate 51, both sides of the cross plate 53 are fixedly installed on the side of the stabilizing frame 47 close to the device body 1, the outer wall of the rotating rod 54 passes through and is rotatably installed inside the cross plate 53, the bottom of the transmission roller 55 is fixedly installed on the top of the rotating rod 54, and the interference flow plates 56 are fixedly installed on the outer wall of the bottom end of the rotating rod 54.

[0024] According to the above technical solution, a reciprocating spiral groove is opened on the outer wall of the rotating rod 54, and the outer wall of the driving roller 55 is in contact with the friction roller 52. If the spoiler plates 56 are equidistantly distributed on the outer wall of the bottom end of the rotating rod 54, the above coordination relies on the spoiler plates 56 to interfere with the regular vibration generated when the seawater impacts the tower base 41 or the floating tower base 45, thereby avoiding the resonance of the tower base 41 and the floating tower base 45 with the impact of seawater, which leads to changes in their own mechanics, thereby generating cracks and causing the risk of seawater intrusion and collapse, thereby extending the overall service life of the equipment to a certain extent.

[0025] The anti-resonance device 5 also includes a sliding ring 57, an inclined plate 58, a bearing plate 59 and a wave plate 510. The sliding ring 57 passes through the inside and is movably installed on the outer wall of the reciprocating spiral groove of the rotating rod 54. The top of the inclined plate 58 is fixedly installed on the left side of the outer wall of the sliding ring 57. The bottom of the bearing plate 59 is fixedly installed on the bottom of the inner wall of the stabilizing frame 47. The outer wall of the wave plate 510 passes through and is slidably installed inside the bearing plate 59. The right side of the wave plate 510 is fixedly installed on the bottom of the inclined plate 58. Through the above cooperation, the wave surface of the wave plate 510 is used to enhance the disturbance effect on the seawater within the range close to the floating ball assembly 49, so that the sea surface around the floating ball assembly 49 is caused to fluctuate, thereby increasing the buoyancy flux, that is, enhancing the jacking effect of the floating ball assembly 49 on the floating tower base 45, and further accelerating the reset speed and wind resistance of the floating tower base 45 on the original basis.

[0026] When in use, the tower seat 41 limits the fixed plate 51, and the fixed plate 51 limits the friction roller 52. When the stabilizing frame 47 revolves around the tower seat 41 as the center, it drives the cross plate 53 to revolve. When the cross plate 53 revolves, it drives the rotating rod 54 to revolve. The rotating rod 54 drives the transmission roller 55 to contact the outer wall of the friction roller 52 to generate friction. At this time, the transmission roller 55 drives the rotating rod 54 along the inside of the cross plate 53 through the friction force to start rotating. The rotating rod 54 drives the spoiler 56 to start rotating, that is, the spoiler 56 realizes rotation during the revolution. Through the above cooperation, the spoiler 56 interferes with the regular vibration generated when the seawater impacts the tower seat 41 or the floating tower base 45, so as to avoid the resonance of the tower seat 41 and the floating tower base 45 with the impact of seawater, resulting in changes in their own mechanics, thereby generating cracks and causing seawater to The risk of collapse caused by injection is reduced, and the service life of the entire equipment is extended to a certain extent; when the rotating rod 54 rotates, the reciprocating spiral groove on its outer wall limits the built-in block of the sliding ring 57, so that the sliding ring 57 is driven by the reciprocating spiral groove to slide downward along the outer wall of the rotating rod 54 and reset, and the sliding ring 57 drives the inclined plate 58 to move synchronously, and the inclined plate 58 pulls the wave plate 510 to slide reciprocatingly downward along the inside of the bearing plate 59 and reset. Through the above cooperation, the wave surface of the wave plate 510 is used to enhance the disturbance effect on the seawater within the range close to the floating ball assembly 49, so that the sea surface around the floating ball assembly 49 is caused to fluctuate, thereby increasing the buoyancy flux, that is, enhancing the jacking effect of the floating ball assembly 49 on the floating tower base 45, and further accelerating the reset speed and wind resistance of the floating tower base 45 on the original basis.

[0027] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-corrosion device 6; The anti-corrosion device 6 includes an L-shaped plate 61, a pressure plate 62 and a rejection frame 63. The top of the L-shaped plate 61 is fixedly installed on the outer wall of the sliding ring 57 near one end of the rotating rod 54. The pressure plate 62 penetrates inside and is slidably installed on the outer wall of the rotating rod 54. The top of the pressure plate 62 is fixedly connected to the bottom of the L-shaped plate 61. The outer wall of the rejection frame 63 is slidably installed on the surface of the spoiler 56 through a spring. The top of the rejection frame 63 contacts the bottom of the pressure plate 62. Through the above cooperation, during the revolution and rotation of the spoiler 56, the reciprocating sliding of the rejection frame 63 further disrupts the impact frequency of the seawater, thereby improving the interference effect of the spoiler 56 on the regular seawater impact on the original basis and reducing the probability of resonance.

[0028] The anti-corrosion device 6 also includes a number of rotating wheels 64, a reciprocating screw rod 65, a sliding plate 66 and a through rod 67. The several rotating wheels 64 are symmetrically and rotatably installed inside the rejection frame 63. Both ends of the reciprocating screw rod 65 are fixedly installed on the side of the rotating wheel 64 close to the center of the rejection frame 63. The sliding plate 66 penetrates inside and is movably installed on the outer wall of the reciprocating screw rod 65. The through rod 67 penetrates the outer wall and is fixedly installed inside the sliding plate 66.

[0029] The outer walls of several wheels 64 are in contact with the outer wall of the spoiler 56, the bottom of the sliding plate 66 is in contact with the bottom of the inner wall of the rejection frame 63, and the outer wall of the sliding plate 66 is in contact with the surface of the spoiler 56. Through the above cooperation, the sliding plate 66 is used to timely remove parasites such as barnacles attached to the surface of the spoiler 56, prevent the rapid reproduction of parasites such as barnacles and aggravate the erosion of the spoiler 56, avoid the accelerated corrosion rate of the spoiler 56, thereby reducing the interference effect on seawater. At the same time, the sliding plate 66 effectively increases the lateral interference force of the rejection frame 63, and effectively improves the auxiliary effect of the rejection frame 63 on the spoiler 56.

[0030] When in use, the sliding ring 57 moves downward and resets, driving the L-shaped plate 61 to move synchronously, and the L-shaped plate 61 drives the pressure plate 62 to slide synchronously along the outer wall of the rotating rod 54. When the pressure plate 62 moves downward, it will contact the top of the rejection frame 63 and exert downward pressure on the rejection frame 63. At this time, the rejection frame 63 will slide downward along the outer wall of the spoiler 56, and then the rejection frame 63 will reset itself by the elastic force of the spring, and repeat this process. Through the above cooperation, during the revolution and rotation of the spoiler 56, the reciprocating sliding of the rejection frame 63 further disrupts the impact frequency of seawater, and improves the interference effect of the spoiler 56 on the regular impact of seawater on the original basis, and reduces the probability of resonance. When the rejection frame 63 slides downward along the outer wall of the spoiler 56, it drives the runner 64 to move synchronously and rub along the outer wall of the spoiler 56, and the runner 64 begins to automatically move inside the rejection frame 63 through friction. The reciprocating screw rod 65 rotates and drives the reciprocating screw rod 65 to rotate. The reciprocating screw rod 65 limits the built-in block of the sliding plate 66 through the reciprocating spiral groove on its outer wall, and the built-in block of the sliding plate 66 constantly contacts the inner wall of the reciprocating spiral groove, so that the sliding plate 66 can slide and reset along the outer wall of the reciprocating screw rod 65 in the direction away from the rotating rod 54. The sliding plates 66 achieve synchronous sliding through the limit of the through rod 67. The sliding plate 66 constantly scrapes the surface of the spoiler plate 56 during the reciprocating sliding and resetting process. Through the above cooperation, the sliding plate 66 is used to timely remove parasites such as barnacles attached to the surface of the spoiler plate 56, so as to prevent the rapid reproduction of parasites such as barnacles and aggravate the erosion of the spoiler plate 56, and avoid the accelerated corrosion rate of the spoiler plate 56, thereby reducing the interference effect on seawater. At the same time, the sliding plate 66 effectively increases the lateral interference force of the rejection frame 63, and effectively improves the auxiliary effect of the rejection frame 63 on the spoiler plate 56.
