The first gear and the second gear are arranged on the outer wall of the vertical pillar from top to bottom along the axial direction of the vertical pillar, and the outer wall of the vertical pillar is provided with elevator gears that can mesh with the first gear and the second gear. Therefore, by simply moving at least one of the first gear and the second gear along the axial direction of the vertical pillar, the distance between the first gear and the second gear can be adjusted, thereby adjusting the distance between the second end of the first connecting rod and the second end of the second connecting rod, and the distance from the first end of the first connecting rod and the first end of the second connecting rod to the outer wall of the vertical pillar, and increasing or decreasing the distance between the turbulence plates installed at the first end of the first connecting rod and the first end of the second connecting rod and the outer wall of the vertical pillar.

The deployed plurality of turbulence plates can reduce the Karman vortex around the vertical shaft and the vortex-induced vibration of the vertical shaft, and further reduce the tilt angle, roll angle and pitch angle of the floating fan, thereby improving the stability of the floating fan and realizing smooth power output of the floating fan.
[0017] When the waves are strong, at least one of the first gear and the second gear is first shifted to reduce the distance between the first end of the first connecting rod, the first end of the second connecting rod, and the vertical shaft, thereby contracting the turbulence plate; then the first gear and the second gear are lowered along the lifting wheel teeth, causing the turbulence plates to lower to a preset heaving position, thereby lowering the center of gravity of the floating vertical shaft and the center of gravity of the entire floating platform; next, at least one of the first gear and the second gear is shifted to increase the distance between the first end of the first connecting rod, the first end of the second connecting rod, and the outer wall of the vertical shaft, thereby further increasing the distance between the turbulence plate and the outer wall of the vertical shaft, thereby deploying the turbulence plate in the heaving position, thereby increasing the damping of the floating vertical shaft, improving the stability of the entire floating fan, and realizing smooth power output of the floating fan.

[0021] As mentioned above, the main objective of the present invention is to provide a floating vertical pillar turbulence structure to enhance the stability of the floating fan.
[0022] The technical solutions of the embodiments of the present invention will be described below clearly and completely with reference to the drawings of the embodiments of the present invention. Of course, the embodiments described here are only a part of the embodiments of the present invention, and do not cover all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.
[0023] As shown in FIGS. 1 to 9, an embodiment of the present invention discloses a floating stand-post turbulence structure, which includes a turbulence plate 100 and a lifting and deploying component 200.
[0024] Here, there are multiple turbulence plates 100, and the lifting and deploying component 200 connects the turbulence plates 100 and the uprights 300. The lifting and deploying component 200 includes a first connecting rod 201, a second connecting rod 202, a first gear 203, and a second gear 204. The first end of the first connecting rod 201 is rotatably connected to the first end of the second connecting rod 202. The turbulence plate 100 is connected to the first end of the first connecting rod 201 and the second connecting rod 204. 2, the second end of the first connecting rod 201 is rotatably connected to the first gear 203, and the second end of the second connecting rod 202 is rotatably connected to the second gear 204. The first gear 203 and the second gear 204 are arranged on the outer circumferential wall of the upright 300 from top to bottom along the axial direction of the upright 300, and elevator gears that can mesh with the first gear 203 and the second gear 204 are installed on the outer circumferential wall of the upright 300.
[0025] When the floating vertical pillar turbulence structure of the present invention is used, the first end of the first connecting rod 201 is rotatably connected to the first end of the second connecting rod 202, the second end of the first connecting rod 201 is rotatably connected to the first gear 203, and the second end of the second connecting rod 202 is rotatably connected to the second gear 204. The first gear 203 and the second gear 204 are arranged on the outer circumferential wall of the vertical pillar 300 from top to bottom along the axial direction of the vertical pillar 300. The outer circumferential wall of the vertical pillar 300 is provided with elevating gear teeth that can mesh with the first gear 203 and the second gear 204, so that the axial direction of the vertical pillar 300 is The distance between the first gear 203 and the second gear 204 can be adjusted by simply moving at least one of the first gear 203 and the second gear 204 along the vertical direction, thereby adjusting the distance between the second end of the first connecting rod 201 and the second end of the second connecting rod 202, and the distance from the first end of the first connecting rod 201 and the first end of the second connecting rod 202 to the outer circumferential wall of the standing rod 300, and thereby increasing or decreasing the distance between the turbulence plate 100 installed at the first end of the first connecting rod 201 and the first end of the second connecting rod 202 and the outer circumferential wall of the standing rod 300. Therefore, the floating standing rod turbulence structure of the present invention has the following advantageous effects:
[0026] When the seawater flow rate is large, at least one of the first gear 203 and the second gear 204 is first moved to reduce the distance between the first end of the first connecting rod 201, the first end of the second connecting rod 202 and the upright 300, thereby contracting the turbulence plate 100; then the first gear 203 and the second gear 204 are moved up along the elevator teeth to lift the multiple turbulence plates 100 to the preset turbulence positions; next, at least one of the first gear 203 and the second gear 204 is moved to increase the distance between the first end of the first connecting rod 201, the first end of the second connecting rod 202 and the outer wall of the upright 300, and further increase the distance between the turbulence plate 100 and the outer wall of the upright 300, thereby realizing the deployment function of the turbulence plate 100. The deployed turbulence plates 100 can reduce the Karman vortex around the vertical column 300 and the vortex-induced vibration around the vertical column 300, and further reduce the tilt angle, rolling angle and pitching angle of the floating fan, thereby improving the stability of the floating fan and realizing smooth power output of the floating fan.
[0027] When the waves are large, at least one of the first gear 203 and the second gear 204 is first moved to reduce the distance between the first end of the first connecting rod 201, the first end of the second connecting rod 202 and the upright 300, so that the turbulence plate 100 is contracted, and then the first gear 203 and the second gear 204 are lowered along the elevating wheel teeth to lower the plurality of turbulence plates 100 to a preset heaving position, thereby lowering the center of gravity of the floating upright and the center of gravity of the entire floating platform. Next, at least one of the first gear 203 and the second gear 204 is moved to increase the distance between the first end of the first connecting rod 201, the first end of the second connecting rod 202 and the outer wall of the stand 300, and further increase the distance between the turbulence plate 100 and the outer wall of the stand 300, so that the turbulence plate 100 is deployed in a heaving position, which increases the damping of the floating stand, improves the stability of the entire floating fan, and realizes smooth power output of the floating fan.
[0028] When the sea is calm, at least one of the first gear 203 and the second gear 204 is moved to reduce the distance between the first end of the first connecting rod 201, the first end of the second connecting rod 202 and the outer wall of the upright 300, thereby reducing the distance between the turbulence plate 100 and the outer wall of the upright 300, and the turbulence plate 100 is contracted to reduce hydraulic power.
[0029] It should be understood that the first connecting rod, the second connecting rod, and the upright portion located between the first gear 203 and the second gear 204 form a triangular structure. If the upright portion between the first gear 203 and the second gear 203 is set as the base of the triangular structure, the height of the triangular structure is the distance between the turbulence plate 100 and the upright portion 300. If the triangular structure is a right-angled triangle, the distance between the turbulence plate 100 and the upright portion 300 is maximum. If the triangular structure is an obtuse-angled triangle, the distance between the turbulence plate 100 and the upright portion 300 can be increased by increasing the distance between the first gear 203 and the second gear 204. If the triangular structure is an acute-angled triangle, the distance between the turbulence plate 100 and the upright portion 300 can be increased by decreasing the distance between the first gear 203 and the second gear 204. Therefore, to realize the deployment function of the turbulence plate 100, the distance between the first gear 203 and the second gear 204 can be increased, or the distance between the first gear 203 and the second gear 204 can be decreased, and either method can be used as long as the turbulence plate 100 can be deployed.
[0030] In addition, the turbulence plate 100 can be fixedly installed to the first end of the first connecting rod 201 and the first end of the second connecting rod 202 using a connecting method such as a bolt or a rivet, or can be rotatably installed to the first end of the first connecting rod 201 or the first end of the second connecting rod 202 using a universal joint bearing or a ball joint, and any connecting method that can meet usage requirements is within the scope of protection of the present invention. Optionally, the turbulence plate 100 provided in the embodiments of the present invention is rotatably installed to the first end of the first connecting rod 201 and the first end of the second connecting rod 202, so that when the turbulence plate 100 is contracted, the turbulence plate 100 can rotate to join with the outer wall of the upright 300, and when the turbulence plate 100 is deployed, the turbulence plate 100 can rotate to form a preset inclination angle with the horizontal plane, making the angle adjustment of the turbulence plate 100 more flexible.
[0031] As shown in Figures 1 and 2, the first end of the first connecting rod 201 and the first end of the first connecting rod 202 are connected via a ball joint, thereby realizing a pivotal connection between the first end of the first connecting rod 201 and the first end of the second connecting rod 202, facilitating adjustment of the distance between the second end of the first connecting rod 201 and the second end of the second connecting rod 202, and further enabling the expansion and contraction of the turbulence plate 100.
[0032] It should be noted that the turbulence plate 100 may be a turbulence mesh, a plate-like object with turbulence nails, or a turbulence plate with turbulence vanes; all structural types that meet the turbulence requirements are within the scope of protection of the present invention. Optionally, as shown in Fig. 7, in one embodiment of the present invention, the turbulence plate 100 is a turbulence mesh, and turbulence action is achieved through the holes in the turbulence mesh. As shown in Fig. 8, in another embodiment of the present invention, the turbulence plate 100 includes a turbulence plate body and turbulence nails installed on the turbulence plate body, and turbulence action is achieved through the protruding turbulence nails.
[0033] In a specific embodiment of the present invention, the number of lifting and lowering components 200 corresponding to each turbulence plate 100 is three, and the three sets of lifting and lowering components 200 are respectively a first lifting and lowering component, a second lifting and lowering component and a third lifting and lowering component. The connection positions of the first lifting and lowering component, the second lifting and lowering component and the third lifting and lowering component with the turbulence plate 100 are distributed triangularly, forming a triangular support structure for the turbulence plate 100 and improving the stability of the turbulence plate 100.
[0034] The lifting teeth can be directly installed on the outer periphery of the support rod 300, i.e., the lifting teeth and the support rod 300 are of an integrated structure. Alternatively, a toothed label 301 can be installed on the outer periphery of the support rod 300, and the lifting teeth can be located on the toothed belt 301, i.e., a separate support rod 300 and toothed belt can be used. Any installation method that meets the requirements for use is within the scope of the present invention.
[0035] Furthermore, the first gear 203 and the second gear 204 are respectively attached to the outer circumferential wall of the stand 300 via the first gear 203 mounting member and the second gear 204 mounting member, and the first gear 203 mounting member and the second gear 204 mounting member are slidably connected to the outer circumferential wall of the stand 300, thereby realizing the meshing and rolling of the elevating wheel teeth of the first gear 203 and the second gear 204, and allowing the turbulence plate 100 to be raised and lowered, deployed and retracted.
[0036] In addition, the floating vertical pillar turbulent flow structure of the present invention further includes a central control system, a seawater flow monitoring system, a wave environment monitoring system, a first pusher for raising and lowering the second end of the first connecting rod 201, and a second pusher for raising and lowering the second end of the second connecting rod 202. The central control system can transmit signals to the seawater flow monitoring system, the wave environment monitoring system, the first pusher, and the second pusher, thereby monitoring seawater flow information (seawater flow speed and direction, etc.) through the seawater flow monitoring system and monitoring wave information (wave height, period, wavelength, etc.) through the wave environment monitoring system. After receiving the seawater flow information and wave information, the central control system The motion status of the floating stand is estimated, and the first pusher and the second pusher are controlled according to the estimated motion status of the floating stand to perform the pushing work, and the first pusher and the second pusher respectively push the first connecting rod 201 and the second connecting rod 202, thereby adjusting the height of the turbulence plate 100 and switching between the expanded and contracted states of the turbulence plate 100, so that the floating stand turbulence structure automatically adjusts the height and state of the turbulence plate 100 according to the seawater flow rate and wave environment, better reducing the vortex-induced vibration, improving the effect of suppressing the horizontal and vertical vibration of the floating fan, further improving the stability of the floating fan, and ensuring the smooth power output of the floating fan.
[0037] The signal transmission method between the central control system, the seawater flow monitoring system, the wave environment monitoring system, the first pusher, and the second pusher may be wired or wireless, and any method that meets the signal transmission requirements is within the scope of protection of the present invention.
[0038] In addition, the present invention also discloses a floating column and a floating fan, both of which include the floating column turbulence structure and combine all the technical effects of the floating column turbulence structure, and will not be further described here.
[0039] In the floating fan shown in Figure 9, the anchor chain of the anchoring system 400 fixes the upright 300 to the seabed, thereby positioning and fixing the floating fan, and the floating fan is installed in a predetermined sea area to generate electricity by utilizing wind power at sea.
