Description

Technical Field

[0001] The invention belongs to the technical field of marine engineering applications, in particular to a floating wind turbine platform using solid buoyancy materials. Background Art

[0002] In recent years, most offshore wind energy development projects have been concentrated in shallow waters close to the coastline. These shallow waters are relatively limited in size and often include functional areas such as harbors, waterways, and tourist attractions. Floating wind turbine development, however, presents a more complex and harsh marine environment in the deep sea. Currently, floating wind turbine platforms include column-type, semi-submersible, and tension-leg platforms. These platforms, driven by waves and currents, generate six degrees of freedom and are equipped with specialized submarine cable protection systems.

[0003] Existing wind turbine platforms on sea level are usually suspended above the sea level by ropes. Although this can prevent the platform from tipping over due to high-speed wind and wave impact to the greatest extent, the platform has poor stability when impacted by normal waves and is very prone to shaking and other problems. Therefore, this type of platform cannot carry people because people on the platform will feel uncomfortable due to frequent shaking. Therefore, it is necessary to design a platform that can stably carry people for scientific research and investigation. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems thereof by adopting a technical solution: a floating wind turbine platform using solid buoyancy material, comprising a carrying device, wherein anchoring devices are evenly arranged on the lower surface of the carrying device, and traction devices are evenly arranged on the lower part of the anchoring device;

[0005] The loading device includes a platform support plate, a guide shaft is fixedly connected to the axis center of the lower surface of the platform support plate, the outer surface of the guide shaft is slidably connected to the diving base plate, and the outer surface of the diving base plate is evenly fixed with fixed connecting rods; the traction device includes a winding drum, the top of the winding drum is rotatably connected to the take-up reel, fixed connecting plates are symmetrically provided on both sides of the outer surface of the winding drum, and the top of the inner cavity of the take-up reel is slidably connected to the limited traction rope;

[0006] The anchoring device includes a bent plug rod and an external sleeve. The interior of the external sleeve is a hollow shell. The inner wall of the bent plug rod is fixedly connected to one end of the submersible base plate with a buffer sealing tape. The buffer sealing tape is made of rubber. Segmented plug rods are symmetrically arranged on both sides of the inner wall of the external sleeve. After the internal rod body of the segmented plug rod is pressurized, the external rod body will slide outward relative to the internal rod body. Water pressure pumps are symmetrically arranged on both sides of the outer surface of the external sleeve. The bottom of the inner wall of the bent plug rod is fixedly connected to a filling device.

[0007] Furthermore, the number of anchoring devices is three. One end of the segmented plug rod is fixedly connected to the inner cavity of the external sleeve, and the other end of the segmented plug rod extends into the interior of the bent plug rod. The end of the segmented plug rod away from the external sleeve is fixedly connected to an internal clamping plate, the inner wall of the internal clamping plate is mutually adapted to the outer surface of the fixed connecting rod, and the water pressure pump discharge port is fixedly connected to the inner cavity of the external sleeve. The end of the fixed connecting rod away from the submersible base extends through a through-hole into the interior of the bent plug rod. The inner wall of the buffer seal is fixedly connected to the outer surface of the fixed connecting rod at its axis. The inner wall of the external sleeve is fixedly connected to the outer surface of the bent plug rod via a fixing plate.

[0008] Furthermore, the submersible base includes a heavy plate shell, with rope slots uniformly formed on the sides of the heavy plate shell. Suspension motors are uniformly disposed within the interior of the heavy plate shell, and the outer surfaces of the output shafts of the suspension motors are rotatably connected to inner-rotating rollers. The top end of the position-limiting traction rope is fixedly connected to the interior of the heavy plate shell via the rope slots. The outer surface of the guide shaft is in rolling connection with the outer surface of the inner-rotating roller. The outer surface of the inner-rotating roller is rotatably connected to the axis of the interior of the heavy plate shell via a rotating groove. The inner-rotating roller drives the top platform support plate to slide up and down by rotating the guide shaft.

[0009] Furthermore, the filling device includes an internal control pump, a bent control rod fixedly connected at the axis of the top of the inner cavity of the internal control pump, touch buttons uniformly arranged at the top of the outer surface of the bent control rod, drainage ports uniformly arranged on the upper surface of the internal control pump, and an anchoring bottom rod fixedly connected at the axis of the lower surface of the internal control pump. The internal control pump can drain water from the seabed through a notch provided at the bottom of the bent rod, and pour seawater into the interior of the bent rod through the drainage port. The outer surface of the internal control pump is fixedly connected to the inner cavity of the bent rod, the top of the outer surface of the anchoring bottom rod is fixedly connected to the bottom of the inner wall of the bent rod, the bottom end of the bent control rod extends into the inner cavity of the internal control pump, and the side surface of the built-in splint and the outer surface of the touch buttons are pressed against each other.

[0010] Furthermore, the fixed connecting plate includes an arcuate connecting plate made of a solid buoyant material to reduce material density and steel usage. A plug-in connecting rod is slidably connected to the middle portion of the outer surface of the arcuate connecting plate. One end of the plug-in connecting rod is fixedly connected to the expansion arcuate plate, and the other end of the plug-in connecting rod is fixedly connected to the pressure-sensitive touch pad via a pressure spring. One end of the arcuate connecting plate is fixedly connected to the outer surface of the anchor base rod, and the other end of the arcuate connecting plate is fixedly connected to the outer surface of the winding drum. The outer surface of the pressure-sensitive touch pad is fixedly connected to the inner cavity of the arcuate connecting plate via a slot.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. Under normal circumstances, the device can control the carrying equipment within a certain movement area through the limiting traction rope, so that the carrying equipment can have a certain movement space when it is impacted by waves, thereby greatly reducing the tension on the anchoring equipment while ensuring that the wind turbine above the platform pallet can work normally. When the staff enters the wind turbine platform above to carry out inspection and maintenance and other related work, the fixed connecting rod is clamped, and the position of the platform pallet is anchored by the fixed connecting rod, so that the wind turbine platform above the platform pallet will not shake due to the action of waves, providing a more stable working environment for the operator, and avoiding the problem of the operator feeling uncomfortable due to the frequent shaking of the platform pallet.

[0013] 2. The device can adjust the actual distance between the platform support plate and the submersible base plate through the suspension motor inside the heavy disk shell, thereby ensuring that the lower surface of the platform support plate after the wind turbine is installed is just above the sea level. The platform support plate will not be immersed below the sea level due to the increase in weight, which will cause the bottom of the motor to be easily soaked in water. The rope slot can be used to increase the connection force between the limit traction rope and the load-carrying equipment, avoiding the problem of separation of the limit traction rope and the heavy disk shell due to loose connection.

[0014] 3. After the relevant personnel leave the platform, release the clamping state of the built-in splint on the fixed link to avoid the problem that the tightened built-in splint is continuously impacted by the waves due to clamping the fixed link for a long time, and then deformed or loosened. At this time, the use of limiting towing rope for anchoring can meet the limiting requirements. By alternating between the fixing methods of limiting towing rope and built-in splint, the workload of the built-in splint due to continuous tightening is reduced, making it less likely that the relevant internal structures of the anchoring equipment will be deformed.

[0015] 4. Since the traction equipment is located at the bottom of the sea level, when the water on the seabed impacts the arc-shaped connecting plate, the expanded arc plate on its outer surface will be forced to push the plug-in connecting rod, and then press the pressure-sensitive touch panel at the corresponding position, thereby feedbacking the impact direction of the water flow inside the seabed. When the impact force is too large, in order to avoid the problem of the limit traction rope breaking, the load-carrying equipment can also be reinforced by a built-in splint to prevent the load-carrying equipment from detaching from the device.

DETAILED DESCRIPTION

[0024] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0025] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a floating wind turbine platform using solid buoyancy materials, comprising a carrier 1, anchoring devices 2 are evenly arranged on the lower surface of the carrier 1, and traction devices 3 are evenly arranged on the lower part of the anchoring devices 2;

[0026] The loading device 1 includes a platform support plate 11, a guide shaft 12 is fixedly connected to the axis center of the lower surface of the platform support plate 11, the outer surface of the guide shaft 12 is slidably connected to the submersible base plate 13, and the outer surface of the submersible base plate 13 is evenly fixed with fixed connecting rods 14; the traction device 3 includes a winding drum 31, the top of the winding drum 31 is rotatably connected to the take-up reel 32, and the two sides of the outer surface of the winding drum 31 are symmetrically provided with fixed connecting plates 5. The top of the inner cavity of the take-up reel 32 is slidably connected to the limited traction rope 33;

[0027] The anchoring device 2 includes a bent plug rod 21 and an external sleeve 22. The interior of the external sleeve 22 is a hollow shell. The inner wall of the bent plug rod 21 is fixedly connected to one end of the diving base plate 13 with a buffer sealing belt 23. The buffer sealing belt 23 is made of rubber. Segmented plug rods 24 are symmetrically arranged on both sides of the inner wall of the external sleeve 22. After the internal rod body of the segmented plug rod 24 is pressurized, its external rod body will slide outward relative to the internal rod body. Water pressure pumps 26 are symmetrically arranged on both sides of the outer surface of the external sleeve 22. The bottom of the inner wall of the bent plug rod 21 is fixedly connected to the filling device 4.

[0028] There are three anchoring devices 2. One end of the segmented plug-in rod 24 is fixedly connected to the inner cavity of the external sleeve 22. The other end of the segmented plug-in rod 24 extends to the inside of the bent plug-in rod 21, and the end of the segmented plug-in rod 24 away from the external sleeve 22 is fixedly connected to the built-in splint 25. The inner wall of the built-in splint 25 is adapted to the outer surface of the fixed connecting rod 14, and the drain outlet of the water pressure pump 26 is fixedly connected to the inner cavity of the external sleeve 22.

[0029] One end of the fixed link 14 away from the diving base plate 13 extends to the inside of the bent insert rod 21 through the through-hole, the axis of the inner wall of the buffer sealing tape 23 is fixedly connected to the outer surface of the fixed link 14, and the inner wall of the external sleeve 22 is fixedly connected to the outer surface of the bent insert rod 21 through a fixing plate.

[0030] The submersible base 13 comprises a heavy plate shell 131, with rope slots 132 uniformly arranged on its sides. Suspension motors 133 are uniformly positioned within the interior of the heavy plate shell 131. The outer surface of the output shaft of the suspension motor 133 is rotatably connected to an inner roller 134. The top of the limiting traction rope 33 is fixedly connected to the interior of the heavy plate shell 131 via the rope slots 132. The outer surface of the guide shaft 12 is in rolling connection with the outer surface of the inner roller 134. The outer surface of the inner roller 134 is rotatably connected to the axis of the interior of the heavy plate shell 131 via a rotating groove. By rotating the guide shaft 12, the inner roller 134 drives the top platform support plate 11 to slide up and down.

[0031] After the device is erected on the sea level, a platform support plate 11 of appropriate size is selected as a supporting base plate according to the size of the platform to be built, and the device is assembled and fixed on its upper surface.

[0032] Under normal circumstances, when there are no staff working on the wind turbine platform above the platform pallet 11, the platform pallet 11 can maintain a certain degree of instability. At this time, the carrying equipment 1 is limited only by the traction device 3, that is, the winding reel 32 slightly tightens the limiting traction rope 33, and the limiting traction rope 33 tightened in three directions limits the submersible base plate 13 to a certain area. Under the cooperation of buoyancy, the platform pallet 11 is ensured not to have the problem of rollover. However, the carrying equipment 1 is more obviously affected by the waves. Because the traction rope cannot completely fix the submersible base plate 13, the carrying equipment 1 will shake with the waves. At this time, the fixed link 14 will slide inside the bent plug rod 21, but with the connection function of the buffer sealing tape 23, the fixed link 14 will not completely slide out from the inside of the bent plug rod 21.

[0033] When the staff enters the wind turbine platform above to carry out inspection and maintenance and other related work, the water pressure pump 26 located below the sea level pressurizes the seawater into the inside of the external sleeve 22, and then the segmented plug-in rods 24 on the inner wall of the external sleeve 22 push the respective built-in clamps 25 in the direction of fitting the fixed link 14 under the action of hydraulic pressure, thereby clamping the fixed link 14. At this time, the fixed link 14 cannot move relatively, and the position of the platform support plate 11 is anchored by the fixed link 14, so that the wind turbine platform above the platform support plate 11 will not shake due to the action of waves.

[0034] After the relevant personnel leave the platform, the clamping and fixing state of the built-in splint 25 on the fixed link 14 is released to avoid the problem that the tightened built-in splint 25 is continuously subjected to the impact of waves due to clamping the fixed link 14 for a long time, and then deformed or loosened. At this time, the limiting traction rope 33 can be used for anchoring.

[0035] Example 2, please refer to Figure 1-Figure 7 The present invention provides a technical solution: Based on Example 1, the filling device 4 includes an internal control pump 41. A bent control rod 44 is fixedly connected to the axis of the top of the inner cavity of the internal control pump 41. Touch buttons 45 are evenly arranged on the top of the outer surface of the bent control rod 44. Drainage ports 43 are evenly arranged on the upper surface of the internal control pump 41. An anchoring bottom rod 42 is fixedly connected to the axis of the lower surface of the internal control pump 41. The internal control pump 41 can drain water from the seabed through the notch provided in the lower part of the bent insertion rod 21, and inject seawater into the interior of the bent insertion rod 21 through the drainage port 43. The outer surface of the internal control pump 41 is fixedly connected to the inner cavity of the bent insertion rod 21. The top of the outer surface of the anchoring bottom rod 42 is fixedly connected to the bottom of the inner wall of the bent insertion rod 21. The bottom end of the bent control rod 44 extends into the inner cavity of the internal control pump 41. The side surface of the built-in clamp 25 and the outer surface of the touch button 45 are pressed against each other.

[0036] The fixed connecting plate 5 includes an arcuate connecting plate 51, which is made of a solid buoyant material to reduce material density and steel usage. A plug-in connecting rod 52 is slidably connected to the middle portion of the outer surface of the arcuate connecting plate 51. One end of the plug-in connecting rod 52 is fixedly connected to an expansion arcuate plate 54, and the other end of the plug-in connecting rod 52 is fixedly connected to a pressure-sensitive touch panel 55 via a pressure spring 53. One end of the arcuate connecting plate 51 is fixedly connected to the outer surface of the anchor base rod 42, and the other end of the arcuate connecting plate 51 is fixedly connected to the outer surface of the winding drum 31. The outer surface of the pressure-sensitive touch panel 55 is fixedly connected to the inner cavity of the arcuate connecting plate 51 via a slot.

[0037] When the built-in splints 25 on both sides clamp the fixed connecting rod 14, the side of the built-in splints 25 will press the touch button 45 on the top of the bending control rod 44. At this time, the internal control pump 41 is started, and the external seawater is pumped into the bending plug rod 21 through the drainage port 43, so that the interior of the bending plug rod 21 is filled with seawater. On the one hand, the built-in splints 25 can be further pressurized by water pressure. On the other hand, the buffer sealing belt 23 expanded by the water pressure will also be tightened, making it difficult for the fixed connecting rod 14 to slide and corrected to the axial position of the bending plug rod 21.

[0038] Since the traction device 3 is located at the bottom of the sea level, when the water on the seabed impacts the arc-shaped connecting plate 51, the expanded arc plate 54 on its outer surface will be forced to push the plug-in connecting rod 52, and then press the pressure-sensitive touch panel 55 at the corresponding position, thereby feeding back the impact direction of the water flow inside the seabed. When the impact force is too large, in order to avoid the problem of the limiting traction rope 33 breaking, the carrying equipment 1 can also be reinforced by the built-in splint 25 to prevent the carrying equipment 1 from detaching from the device.

[0039] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
