[0021] As mentioned above, the main objective of the present invention is to provide a floating vertical pillar turbulent 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 herein are only a part of the embodiments of the present invention, and are not 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 the subject of protection of the present invention.

[0023] As shown in FIGS. 1 to 9, an embodiment of the present invention discloses a floating vertical pillar 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 lowering deployment component 200 connects the turbulence plates 100 and the uprights 300. The lifting and lowering deployment 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 pillar 300 from top to bottom along the axial direction of the upright pillar 300, and the outer circumferential wall of the upright pillar 300 is provided with elevator gears that can mesh with the first gear 203 and the second gear 204.

[0025] When the floating vertical column turbulent flow structure of the present invention is used, the first end of the first connecting rod 201 is pivotally connected to the first end of the second connecting rod 202, the second end of the first connecting rod 201 is pivotally connected to the first gear 203, and the second end of the second connecting rod 202 is pivotally 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 column 300 from top to bottom along the axial direction of the vertical column 300, and the outer circumferential wall of the vertical column 300 is provided with lifting gears that can mesh with the first gear 203 and the second gear 204, so that the axial direction of the vertical column 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, 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 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, firstly, 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 standing pillar 300, so as to contract the turbulence plate 100, and then the first gear 203 and the second gear 204 are lifted along the lifting wheel teeth to lift the multiple turbulence plates 100 to the preset turbulence positions, and then, 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 peripheral wall of the standing pillar 300, and further increase the distance between the turbulence plate 100 and the outer peripheral wall of the standing pillar 300, so as to realize the deployment function of the turbulence plate 100. Through the deployment of multiple turbulence plates 100, the Karman vortex around the stand 300 and the vortex-induced vibration around the stand 300 can be reduced, and the inclination angle, rolling angle and pitch angle of the floating fan can be reduced, so that the stability of the floating fan can be improved and the smooth power output of the floating fan can be realized.

[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 stand 300, so as to contract the turbulence plate 100, and then the first gear 203 and the second gear 204 are lowered along the lifting wheel teeth to lower the multiple turbulence plates 100 to a preset heaving position, thereby lowering the center of gravity of the floating stand 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 peripheral wall of the standing pillar 300, and further increase the distance between the turbulence plate 100 and the outer peripheral wall of the standing pillar 300, so that the turbulence plate 100 is deployed in a heaving position, which increases the damping of the floating standing pillar, 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 peripheral wall of the upright pillar 300, thereby reducing the distance between the turbulence plate 100 and the outer peripheral wall of the upright pillar 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 adopted as long as the turbulence plate 100 can be deployed.

[0030] In addition, the turbulence plate 100 can be fixedly installed at the first end of the first connecting rod 201 and the first end of the second connecting rod 202 by a connecting method such as a bolt or a rivet, or can be rotatably installed at the first end of the first connecting rod 201 or the first end of the second connecting rod 202 by a universal joint bearing or a ball joint, and any connecting method that can meet the requirements for use is protected by the present invention. Optionally, the turbulence plate 100 provided in the embodiment of the present invention is rotatably installed at 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 standing column 300, and when the turbulence plate 100 is deployed, the turbulence plate 100 can rotate until it forms 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, making it convenient to adjust the distance between the second end of the first connecting rod 201 and the second end of the second connecting rod 202, and further realizing the deployment and contraction of the turbulence plate 100.

[0032] It should be noted that the turbulence plate 100 can be a turbulence net, a plate-like object with turbulence nails, or a turbulence plate with turbulence vanes, and all structural types that meet the turbulence requirements are within the scope of the present invention. Optionally, as shown in Fig. 7, in one embodiment of the present invention, the turbulence plate 100 is a turbulence net, and the turbulence effect is achieved through the holes in the turbulence net. 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 the turbulence effect is achieved through the protruding turbulence nails.

[0033] In a specific embodiment of the present invention, the number of lifting and lowering deployment components 200 corresponding to each turbulence plate 100 is three, and the three sets of lifting and lowering deployment components 200 are a first lifting and lowering deployment component, a second lifting and lowering deployment component and a third lifting and lowering deployment component, respectively. The connection positions of the first lifting and lowering deployment component, the second lifting and lowering deployment component and the third lifting and lowering deployment component and the turbulence plate 100 are distributed in a triangle, so as to form a triangular support structure for the turbulence plate 100 and improve the stability of the turbulence plate 100.

[0034] In addition, the lifting teeth can be directly installed on the outer circumferential wall of the stand 300, that is, the lifting teeth and the stand 300 are an integral structure. Or, a toothed label 301 is installed on the outer circumferential wall of the stand 300, and the lifting teeth are located on the toothed belt 301, that is, a split structure of the stand 300 and toothed belt is 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 mounted on 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 on the lifting and lowering wheel teeth of the first gear 203 and the second gear 204, and enabling the turbulence plate 100 to be lifted 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. The central control system receives the seawater flow information and the wave information and then 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 push the first connecting rod 201 and the second connecting rod 202 respectively, thereby adjusting the height of the turbulence plate 100 and switching between the expanded and contracted states of the turbulence plate 100. This makes the floating stand turbulence structure automatically adjust the height and state of the turbulence plate 100 according to the seawater flow rate and wave environment, thereby better reducing the vortex-induced vibration, improving the effect of suppressing the lateral 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 transmission or wireless transmission, 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 have all the technical effects of the floating column turbulence structure, and will not be described further 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 pre-designated sea area to generate electricity by utilizing wind power at sea.
