[0002] With the rapid development of social economy, the demand for energy in countries around the world has increased dramatically. In order to solve the problem of the depletion of non-renewable energy resources and the deteriorating environment, it has become a consensus among countries around the world to find renewable and clean new energy. As the main body of the earth's area accounting for 70%, the ocean not only has rich resources such as aquatic products and oil, but also contains huge energy. Offshore wind power, a marine energy, has developed rapidly and on a large scale.

[0003] Generally speaking, offshore wind turbine structures need to ensure the stability of the wind turbine foundation. The existing technology generally adopts the method of adjusting the posture to achieve the stability of the wind turbine foundation. This method easily leads to a low fatigue service life of the wind turbine foundation, low structural safety during long-term use, and requires more frequent maintenance, replacement of parts and other operations. Summary of the invention

[0004] The purpose of the present invention is to address the problem that the existing method of achieving wind power foundation stability easily leads to wind power foundation fatigue. The present invention proposes an offshore wind power foundation anti-scour device.

[0006] Preferably, the rotating mechanism comprises a rotating groove, which is opened inside the guide plate, a support plate is fixedly connected to the surface of the inner wall of the rotating groove, a vertical rod is fixedly connected to the inner side of the support plate, and a first gear is movably connected to the surface of the vertical rod.

[0007] Preferably, a second external gear is meshed with the surface of the first gear, the interior of the second external gear is fixedly connected to the support rod, and the inner side of the second external gear is a second internal gear.

[0008] Preferably, the number of the second external gears is not less than two, and the surface of each of the second external gears is meshed with not less than two first gears.

[0009] Preferably, the support mechanism includes a first support ring fixedly arranged on the surface of the open connection cylinder. The inner and outer surfaces of the open connection cylinder are smoothly arranged, and the upper and lower ends are fixedly connected with a rotating mechanism. The top of the first support ring is fixedly connected with a positioning frame. A ball is rotatably connected inside the positioning frame. The top of the ball is movably connected with a second support ring. The outer side of the second support ring is fixedly connected with the inner wall surface of the rotating groove. An ascending motor and a descending motor are respectively fixed on the second support ring. A metal shell is fixedly connected to the outer side of the flow deflector, and a polyethylene layer is fixedly connected to the outer side of the metal shell.

[0010] Preferably, the number of the balls is several, and the balls are evenly distributed in a ring shape.

[0011] Preferably, the sliding mechanism includes a fixed ring fixedly connected with the support rod. A sliding groove is arranged on the outer surface of the fixed ring. An ascending sliding gear and a descending sliding gear are arranged at both ends of the opening of the sliding groove. The ascending sliding gear is in gear engagement with the ascending motor gear, and the descending sliding gear is in gear engagement with the descending motor gear.

[0012] Preferably, the wave detection mechanism includes a floating ball support frame. A floating ball is sleeved on the floating ball support frame. The floating ball is connected with a balance pipe on one side close to the support rod. The other end of the balance pipe is fixed with a balance pipe rotating ring. The balance pipe rotating ring is sleeved on a balance pipe rotating shaft fixedly connected with the flow deflector. A descending contact end and an ascending contact end are arranged at both ends of the balance pipe, and an induction ball is arranged inside the balance pipe.

[0013] Preferably, the floating ball support frame is fixedly arranged on the surface of the flow deflector perpendicular to the sea level direction, and the floating ball support frame is in an arc shape.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the seawater impacts the flow deflector in this solution, through the streamline design of the flow deflector, it is convenient to efficiently guide the seawater. The rotation of the flow deflector drives the support plate and the vertical rod to rotate, so that the first gear rotates around the second gear, thus achieving efficient rotation and facilitating the decomposition of seawater, and improving the impact resistance ability.

[0015] 2. In this solution, the second support ring rolls on the top of the balls to support the flow deflector. Through the arrangement of the first support ring and the positioning frame, it is convenient to limit the balls, improve the rotation stability of the balls, and facilitate the user to use. At the same time, the polyethylene layer improves the smoothness of the surface of the flow deflector and prevents a large number of marine organisms from adsorbing on its surface.

[0016] 3. In this solution, by setting relevant structures, when a wave propagates, the wave will cause the floating ball to float upward. The upward floating of the floating ball will drive the balance pipe to rotate upward. At this time, the sensing ball will move along the balance pipe towards the upward contact end. When it moves to the upward contact end and touches it, the upward motor will be immediately started. The upward motor gear installed on the upward motor will start to rotate, driving the upward sliding gear meshing with it to make the entire deflector device slide upward until the sensing ball leaves the upward contact end, and then the upward motor will be cut off. Similarly, when the wave propagates away, the wave will cause the floating ball to float downward. The upward floating of the floating ball will drive the balance pipe to rotate downward. At this time, the sensing ball will move along the balance pipe towards the downward contact end. When it moves to the downward contact end and touches it, the downward motor will be immediately started. The downward motor gear installed on the downward motor will start to rotate, driving the downward sliding gear meshing with it to make the entire deflector device slide downward until the sensing ball leaves the downward contact end, and then the downward motor will be cut off. In this way, the entire deflector device will always be in the horizontal plane position, thus enabling efficient up and down sliding, facilitating the decomposition of seawater, and improving the impact resistance ability.

[0019] Example 1: As Figure 1 - Figure 8 shown, an anti-erosion device for an offshore wind power foundation includes: a generator 1, a support rod 2 fixedly connected to the bottom of the generator 1, a deflector 3 arranged on the surface of the support rod 2, curved panels 4 fixedly connected to both the top and bottom of the deflector 3, sealing rings 5 fixedly installed on both the top and bottom of the curved panels 4, and a photovoltaic panel installed on the top of the curved panel 4 to provide power for the lifting motor. The inner side of the sealing ring 5 is slidably connected to the support rod 2. The hollow position inside the deflector is set as a floating body mechanism, and the buoyancy of the floating body mechanism can make the entire deflector float on the water surface. A sliding mechanism 8 is arranged on the surface of the support rod 2, and the sliding mechanism 8 is fixedly connected to the surface of the support rod 2. The sliding mechanism 8 is used to slide the deflector 3 up and down. A support mechanism 7 is arranged in the middle of the rotating mechanism 6 to support the deflector 3. A wave detection mechanism 9 is arranged on the wave impact surface of the deflector 3. The wave detection mechanism 9 can efficiently detect waves and adjust the deflector 3 up and down. The rotating mechanism 6 is arranged to facilitate the efficient rotation of the deflector 3 and adjust the angle through the water flow, reducing the resistance of the water flow, thereby improving the stability and safety of the wind power device during use.

[0020] As Figures 1 to 6As shown in the figure, the rotating mechanism 6 includes a rotating groove 61 which is formed inside the flow guiding plate 3. A support plate 62 is fixedly connected to the inner wall surface of the rotating groove 61. A vertical rod 63 is fixedly connected to the inner side of the support plate 62. A first gear 64 is movably connected to the surface of the vertical rod 63. The provision of the rotating groove 61 facilitates the connection between the flow guiding plate 3 and the support rod 2. At the same time, the provision of the support plate 62 facilitates the fixation of the first gear 64, thereby improving the stability of the rotation of the flow guiding plate 3. The second internal gear 66 meshes with the chute 81 of the sliding mechanism. The surface of the first gear 64 meshes with a second external gear 65. The rotation of the second external gear 65 causes the flow guiding plate 3 to rotate around the support rod 2 through the first gear 64, improving the rotation efficiency. The second external gear 65 and the second internal gear 66 are actually the same gear with internal and external gear grooves. The second external gear 65 is used for the rotation of the flow guiding plate 3, and the second internal gear 66 is used for the up and down sliding of the flow guiding plate 3. Four first gears 64 are meshed with the surface of each second external gear 65. The number of the second external gears 65 is set to two, which facilitates higher stability of the support when the flow guiding plate 3 rotates, thereby improving the decomposition ability of the seawater impact and facilitating the use by the user.

[0021] In the embodiment of the present invention (working principle), when in use, when the user impacts the flow guiding plate 3 with seawater, due to the streamline design of the flow guiding plate 3, it is convenient to efficiently guide the seawater. The rotation of the flow guiding plate 3 drives the support plate 62 and the vertical rod 63 to rotate, so that the first gear 64 rotates around the second external gear 65, thereby achieving efficient rotation. And the wave detection mechanism 9 detects the waves, so as to achieve efficient up and down sliding, facilitating the decomposition of the seawater and improving the impact resistance ability.

[0022] Such as Figures 1 to 8As shown in the figure, the support mechanism 7 includes a first support ring 71. The first support ring 71 is fixedly installed on the open connection cylinder 77. The inner and outer surfaces of the open connection cylinder 77 are smoothly arranged and have an opening. The opening is for facilitating the engagement between the lifting motor gear and the lifting sliding gear. The upper and lower ends are fixedly connected to the rotating mechanism 6. The inner surface of the open connection cylinder 77 is kept at a certain distance from the surface of the chute, which does not affect the up and down sliding of the deflector 3. The top of the first support ring 71 is fixedly connected with a positioning frame 72. Inside the positioning frame 72, there is a rolling connection with a ball 73. The setting of the first support ring 71 facilitates the weight of the deflector 3 to be supported by the first support ring 71, thereby improving the stability and efficiency of the rotation of the deflector 3, and facilitating the user to use. Through the setting of the ball 73, it is convenient to reduce the friction when the deflector 3 rotates, thereby improving the rotation efficiency and the efficiency of resisting the impact of seawater. The top of the ball 73 is movably connected with a second support ring 74. The outer side of the second support ring 74 is fixedly connected to the inner wall surface of the rotating groove 61. By fixedly connecting the second support ring 74 to the surface of the rotating groove 61, through the support of the first support ring 71 and the ball 73, the second support ring 74 and the deflector 3 are supported. And an ascending motor 10 and a descending motor 12 are respectively fixed on the second upper and lower support rings 74. The elevator is a battery elevator, and the electric energy comes from the photovoltaic panel 14 installed on the top of the curved panel 4. The number of balls 73 is several, and the balls 73 are evenly distributed in a ring. By setting the number of balls 73 to several, the stability of the rotation of the second support ring 74 is improved, and thus the stability of the rotation of the deflector 3 is improved. The outer side of the deflector 3 is fixedly connected with a metal shell 75. The outer side of the metal shell 75 is fixedly connected with a polyethylene layer 76. The setting of the metal shell 75 effectively improves the impact resistance of the deflector 3. Through the setting of the polyethylene layer 76, the smoothness of the surface of the deflector 3 is improved.

[0023] In the embodiment of the present invention, the second support ring 74 rolls on the top of the ball 73, thereby supporting the deflector 3. Through the setting of the first support ring 71 and the positioning frame 72, it is convenient to limit the ball 73, improve the stability of the rotation of the ball 73, and facilitate the user to use. At the same time, the polyethylene layer 76 improves the smoothness of the surface of the deflector 3, preventing a large number of marine organisms from adsorbing on its surface.

[0024] As Figures 1 to 8 shown, the sliding mechanism 8 is provided with a fixed ring 84. The inner surface of the fixed ring 84 is fixedly connected to the support rod 2. The outer surface of the fixed ring 84 is provided with a chute 81. The chute 81 is an open setting. The open setting is for facilitating the engagement between the lifting motor gear and the lifting sliding gear. At both ends of the opening, an ascending sliding gear 82 and a descending sliding gear 83 are provided. The ascending sliding gear 82 is engaged with the ascending motor gear 11, and the descending sliding gear 83 is engaged with the descending motor gear 13.

[0025] AsFigures 1 to 8 As shown, the wave detection mechanism 9 is arranged on the wave impact surface of the flow deflector 3. A balance pipe 92 is arranged on the wave detection mechanism 9. On one side of the balance pipe 92, a circular hole is opened on the flow deflector 3, and a balance pipe rotating shaft 95 is fixed on the circular hole. The balance pipe 92 can rotate around the balance pipe rotating shaft 95 through a balance pipe rotating ring 96. On the other side, a floating ball 93 is fixed. The floating ball 93 can move up and down with the waves through a floating ball support frame 94. The floating ball support frame 94 is arranged in an arc shape and fixed on the surface of the flow deflector 3. It is arranged in an arc shape because the balance pipe 92 makes a circular motion around the balance pipe rotating ring 96. An induction ball 91 is arranged in the balance pipe 92. The induction ball 91 can slide freely in the balance pipe 92, and a downward contact end 97 and an upward contact end 98 are arranged at both ends of the balance pipe 92. When the wave propagates, the wave will make the floating ball 93 float upward. The upward floating of the floating ball 93 will drive the balance pipe 92 to rotate upward. At this time, the induction ball 91 will move along the balance pipe 92 towards the upward contact end 98. When it moves to the upward contact end 98 and contacts it, the upward motor 10 will be immediately started. The upward motor gear 11 installed on the upward motor 10 starts to rotate, driving the upward sliding gear 82 meshing with it to make the entire flow deflector device slide upward by 3 until the induction ball 91 leaves the upward contact end 98, and then the upward motor 10 is cut off. Similarly, when the wave propagates away, the wave will make the floating ball 93 float downward. The upward floating of the floating ball 93 will drive the balance pipe 92 to rotate downward. At this time, the induction ball 91 will move along the balance pipe 92 towards the downward contact end 97. When it moves to the downward contact end 97 and contacts it, the downward motor 12 will be immediately started. The downward motor gear 13 installed on the downward motor 12 starts to rotate, driving the downward sliding gear 83 meshing with it to make the entire flow deflector device 3 slide downward until the induction ball 91 leaves the downward contact end 97, and then the downward motor 12 is cut off. In this way, the entire flow deflector device 3 will always be in the horizontal position, so as to perform efficient up and down sliding, facilitate the decomposition of seawater, and improve the impact resistance. The balance pipe is arranged in an arc shape to make the induction ball 91 in the balanced position when detecting the propagation of smaller waves and not start the elevator.
