Technical Field

[0001] The present invention belongs to the technical field of buoy systems, and particularly relates to a long-term monitoring buoy system for an offshore wind farm. Background Art

[0002] The description of this part only provides background information related to the disclosure of the present application, and does not constitute prior art.

[0003] The ocean covers three-fourths of the earth's area and is one of the main factors determining the climate development on earth. It directly affects the energy cycle and material cycle among the ocean, land, and atmosphere. However, the ocean is a place full of changes, sometimes rough and sometimes calm. The ocean contains a large amount of resources that can be exploited by humans for the benefit of mankind. At the same time, the unpredictability of the ocean often brings great disasters to humans. Therefore, in order to better utilize ocean resources and reduce disasters, people are paying more and more attention to the monitoring of the ocean environment and establishing ocean observation stations to measure information such as wave height and wind speed.

[0004] After the buoy calculates the original data obtained from sampling in the buoy, it transmits the true values of the obtained parameters back to the receiving shore station through any one of satellite communication, GPRS, VHF radio, etc. The shore station database interface automatically updates the display and saves them. It realizes an integrated water monitoring platform that is unattended, continuous, and online. At the same time, it can be combined with satellite remote sensing to form an overall water quality distribution map, observe long-term data, and analyze the ecological changes of lakes in each basin.

[0005] The prior art is the invention patent with the publication number US8149275B2, and the invention name is "Monitoring buoy system". This invention discloses a fixed-position buoy for observing and monitoring the surface of a predetermined water area, including a flotation device; an imaging device operable to obtain an image of the water surface of the predetermined area; a memory for storing the image of the water surface of the predetermined area; one or more communication devices operable to send a signal representing the image of the water surface of the predetermined area to a remote location; and a tether and mooring device attached to the flotation device, the tether and mooring device being operable to fix the flotation device. This invention provides a reliable and inexpensive observation and monitoring system that can transmit continuous and real-time images of a large predetermined area of the water surface to an operator at a remote location. The stability of this invention is insufficient.

[0006] It should be noted that the above introduction to the technical background is only for the convenience of clearly and completely explaining the technical solution of the present application and facilitating the understanding of those skilled in the art. It cannot be considered that the above technical solutions are well-known to those skilled in the art just because these solutions are described in the background art part of the present application. Summary of the Invention

[0007] The object of the present invention is to provide an offshore wind farm long-term monitoring buoy system with good monitoring effect, long service life and high stability.

[0008] The technical solution adopted by the present invention to achieve the above-mentioned purpose is:

[0009] A long-term monitoring buoy system for an offshore wind farm includes a plurality of detection buoys. A connecting net rope is provided between adjacent detection buoys. The detection buoy includes a buoy base. A stabilizing component is provided at intervals at the bottom of the buoy base. The stabilizing component is used to control the range of movement of the floating base. An observation component and a power supply component are provided on the floating base.

[0010] According to an embodiment of the present invention, the observation component includes a camera and a hydrological monitoring device.

[0011] Through the setting of the overall device, multiple detection buoys are set around the offshore wind farm. The offshore wind farm is monitored in real time through the observation components set on the multiple detection buoys. The observation components are powered by the power supply components to ensure long-term operation. The data collected by the observation components can be transmitted to the ground base station through radio or satellite communication systems. The ground base station can realize automatic data analysis and manual judgment to ensure the normal operation of the offshore wind farm. The observation component includes a camera and a hydrological monitoring device. The offshore wind farm can be monitored in real time by video through the camera. At the same time, when the operation and maintenance personnel are inspecting and repairing each detection buoy, the camera can be used to observe a single detection buoy in real time and communicate with the operation and maintenance personnel, and communicate and guide the operation and maintenance projects and processes in real time; the local ocean hydrology can be detected through the hydrological detection equipment. Through hydrological monitoring, not only can various geological disasters be predicted and prepared in advance to reduce the losses caused by sudden accidents to the offshore wind farm, but also various data in various sudden accidents can be recorded and analyzed through data to optimize and improve the offshore wind farm in a targeted manner. The stabilization component is used to ensure that the detection component is in a relatively stable state and position.

[0012] By setting connecting net ropes between each buoy, the detection buoys can be made more stable, and the moving range of the detection buoy can be controlled, making the entire buoy system more stable; in addition, the connecting net ropes can block water flow and floating objects or other garbage, which is beneficial to reduce the speed of water flow into the offshore wind farm, and can also prevent floating garbage at sea or garbage in the water from causing damage to the offshore wind farm, thereby protecting the offshore wind farm.

[0013] Furthermore, the observation equipment is provided with a positioning system. By providing a GPS positioning system or a Beidou positioning system on each detection buoy, the position of the individual detection buoy can be monitored to prevent the detection buoy from being lost due to force majeure or other accidents and being unable to be found.

[0014] Furthermore, a flashing light is provided on the buoy substrate, which can be used to warn nearby fishing boats or other ships, especially at night, so that the ships can turn or turn around when they see the flashing light, which can effectively protect the offshore wind farm.

[0015] According to one embodiment of the present invention, the stabilizing assembly includes a counterweight column, a ring plate is arranged around the top of the outer side of the counterweight column, a plurality of bent ring plates are sleeved on the outer side of the counterweight column, the plurality of bent ring plates are arranged in parallel and spaced apart, the bent ring plates are equidistantly provided with a plurality of through holes, a plurality of second anchor ropes are arranged at the bottom of the ring plate, the second anchor ropes are arranged corresponding to the through holes, and the second anchor ropes pass through the through holes and are connected to the counterweight assembly;

[0016] The top of the counterweight column is connected to the bottom of the buoy base through a first anchor rope.

[0017] The top of the counterweight column is connected to the bottom of the floating base through the first anchor rope, which can move the center of the whole device downward, ensure the stability of the whole device, and prevent the floating base from tipping over or seriously deviating from the preset position under the impact of waves. Multiple bending ring plates are arranged outside the counterweight column. When the water flows through the bending ring plates, the bending ring plates will move up and down along the movement trajectory of the water flow, so that the multiple bending ring plates have a suspension effect. The second anchor rope passes through the through holes arranged at intervals in the bending ring plates. The up and down movement of the bending ring plates can cause the counterweight column to move up and down, and then the counterweight column can cause the first anchor rope on its upper part to pull up and down. In this way, the floating range of the buoy in the water surface under the action of the water flow is too large, that is, the floating range of the buoy on the water surface is reduced by the up and down pulling effect. The bottom of the second anchor rope is connected to a counterweight assembly, which is used to control the displacement range of the counterweight column.

[0018] According to an embodiment of the present invention, a brush is provided on one side of the bent ring plate close to the counterweight column.

[0019] A brush is provided on the side of the bending ring plate close to the counterweight column. The bending ring plate will move up and down with the flow of water. The brush can move with the bending plate so that the brush contacts the counterweight column, and then the surface of the counterweight column and the second anchor rope is cleaned by the brush, which is helpful to prevent parasites from attaching to the counterweight column and the second anchor rope, and prevent the counterweight column or the second anchor rope from being damaged or failing. In addition, through the provision of the brush, the overall contact area of the bending ring plate with the water body can be made larger, thereby increasing the amplitude and effect of the up and down movement of the bending ring plate, and further improving the effect of the brush.

[0020] According to an embodiment of the present invention, the counterweight assembly includes a counterweight base column. A base plate is provided at the bottom end of the counterweight base column. A bent mesh plate is provided around the base plate. A bent rod body is provided on the side of the bent mesh plate close to the base plate, and the bent rod body is connected to the side of the base plate.

[0021] A connection hole is provided at the top end of the counterweight base column, and the connection hole is used for connecting with the second anchor rope.

[0022] The counterweight assembly is connected with a second anchor rope, that is, multiple counterweight assemblies are connected to and act on the counterweight column. The second anchor ropes are equidistantly wound around the connecting ring plate, ensuring that the multiple counterweight assemblies are evenly distributed around the counterweight column. Thus, it can cope with the displacement of the counterweight column in all directions, control the displacement range of the detection buoy, improve the stability of the detection buoy, and further reduce the situation that the detection buoy moves out of the detection range due to large movement of the detection float caused by wind, waves or other factors. In addition, by providing a base plate at the bottom end of the counterweight column, the center of gravity of the counterweight assembly can be lowered, and the contact between the counterweight assembly and the seabed surface can be improved, enhancing the fixing effect, that is, improving the effect produced by the counterweight assembly. A bent mesh plate is provided around the base plate. The bent mesh plate is a multi-mesh structure with elasticity. When the counterweight assembly sinks to the seabed, when the counterweight assembly contacts the seabed structure (such as a reef), the elastic deformation of the bent mesh plate can be used to avoid damage to the reef or other seabed structures. And when the bent mesh plate is elastically deformed, the sediment between the bent and extruded mesh plate and the base plate is utilized, and this effect is used to slow down the movement of the counterweight assembly on the seabed under the impact of water body or other biological interference. In addition, under the impact of water flow, the bent mesh plate can fix part of the sediment brought by the water flow, thereby ensuring the fixing effect of the counterweight assembly.

[0023] Furthermore, leaf plates are provided around the counterweight base column, and the leaf plates connect the base plate and the counterweight base column. The leaf plates can improve the strength of the counterweight assembly. At the same time, the leaf plates and the bent mesh plate act together to form the effect of a fish reef, and the sediment and organisms accumulate on the counterweight assembly to improve the counterweight effect.

[0024] Furthermore, the leaf plates are also connected to the bent rod bodies. Connecting the leaf plates to the bent rod bodies improves the overall strength of the bent mesh plate counterweight assembly.

[0025] In an embodiment of the present invention, a plurality of protective frames are provided around the buoy body. At least one roller is provided on the side of the protective frame away from the buoy body, and the roller is rotatably connected to the protective frame. A buffer space is provided on the side of the protective frame close to the buoy body.

[0026] A buffer space is provided on one side of the protective frame close to the buoy base. In the case of the buoy base being impacted or collided, the buffer space can compress or undergo elastic deformation to absorb the impact force, reduce the impact of waves on the buoy, and play a protective role. By providing at least one roller on the side of the protective frame away from the buoy base, the roller is rotatably connected to the protective frame. Thus, the roller can rotate with the flow of water, and the rotation of the roller can reduce the impact force generated by the transverse and longitudinal waves of the sea on the buoy base. The rolling of the roller can also reduce the impact of accidentally approaching fishing boats or other vessels on the buoy base, protecting the buoy base. In addition, the roller can provide buoyancy to the detection buoy to prevent the detection buoy from toppling under the impact of large waves and winds.

[0027] According to an embodiment of the present invention, the roller includes a transparent roller shaft and a transparent roller shell. The transparent roller shell is hollow inside, and an ultraviolet lamp is provided inside the transparent roller shaft.

[0028] By providing an ultraviolet lamp inside the roller shaft of the same name, the attachment of organisms to the buoy base and the transparent roller can be avoided by regularly turning on and off the ultraviolet lamp. The rotational movement of the transparent roller can cut down waves and also change the refraction of ultraviolet light to increase the scope of removing attachments, ensuring that there are no attached aquatic organisms near the rotating part of the roller shaft, so that the roller shaft can rotate normally.

[0029] Furthermore, the transparent roller shaft is provided as a light-transmitting structure. The transparent roller shaft is preferably made of quartz glass structure.

[0030] According to an embodiment of the present invention, the connecting net rope includes a barrier net body. A plurality of barrier floats are provided on the barrier net body, and the barrier net body is connected to the buoy base through a third anchor rope.

[0031] By providing the barrier net body, the speed of water entering the offshore wind farm can be reduced, and at the same time, the detection accuracy of the measurement component for water can be improved, ensuring the accuracy of the overall device. In addition, by providing the barrier floats, the impact of marine floating objects on the barrier net body can be reduced, and the situation of the barrier net body being broken due to the impact of floating objects or other garbage on the barrier net body can be avoided. The barrier floats can provide a certain buoyancy, that is, make part of the barrier net body float on the water surface, so that the barrier net body can collect sundries or garbage floating on the water surface or flowing with the water under the water, ensuring the safety of the inner waters of the offshore wind farm.

[0032] According to an embodiment of the present invention, the power supply component includes a plurality of solar panels and an energy storage component. The plurality of solar panels are equidistantly arranged on the buoy base, and the solar panels are connected to the energy storage component. The energy storage component is used to supply energy to the observation component.

[0033] When the solar panel is powered, it will directly supply energy to the observation component through the energy storage component, providing energy for the observation component to ensure the normal observation of the observation component; when the solar panel cannot supply power, such as at night or in bad weather, it will directly supply power to the observation component through the energy storage component to ensure the normal operation of the overall device.

Detailed implementation manners

[0048] The technical solutions of the present invention will be further described in detail below in conjunction with the detailed implementation manners and the drawings:

[0049] Embodiment 1:

[0050] As Figure 1 、 2 shown in FIGS. 3, 4, 5, 6, and 7, an offshore wind farm long-term monitoring buoy system includes a plurality of detection buoys 1, a connecting net rope 2 is provided between adjacent detection buoys 1, the detection buoy 1 includes a buoy base 10, a stabilizing assembly 11 is provided at intervals at the bottom of the buoy base 10, the stabilizing assembly 11 is used to control the movement range of the buoy base 10, and an observation assembly and a power supply assembly are provided on the buoy base 10.

[0051] The observation assembly includes a camera 102 and a hydrological monitoring device 103.

[0052] By setting up the overall device, a plurality of detection buoys 1 are arranged around the offshore wind farm 3. The offshore wind farm 3 is monitored in real time through the observation components arranged on the plurality of detection buoys. The power supply component supplies power to the observation components to ensure long-term operation. The data collected by the observation components can be transmitted to the ground base station through radio or satellite communication systems. The ground base station can perform automatic data analysis and manual judgment to ensure the normal operation of the offshore wind farm 3. The observation components include a camera 102 and a hydrological monitoring device 103. Through the camera 102, real-time video monitoring of the offshore wind farm 3 can be carried out. At the same time, during the maintenance process of each detection buoy 1 by the operation and maintenance personnel, a certain detection buoy can be observed in real time through the camera 102 and communication with the operation and maintenance personnel can be carried out, and real-time communication and guidance on the operation and maintenance projects and processes can be carried out; through the hydrological detection device, the local marine hydrology can be detected. Through hydrological monitoring, not only can early predictions and preparations be made for various geological disasters to reduce the losses caused by sudden accidents to the offshore wind farm 3, but also various data can be recorded during various sudden accidents and analyzed through the data to optimize and improve the offshore wind farm 3 targeted. The stabilization component 11 is used to ensure that the detection component is in a relatively stable state and position.

[0053] By arranging a connecting net rope 2 between each buoy, through the setting of the connecting net rope 2, the detection buoys can be made more stable, the moving range of the detection buoy 1 can be controlled, and the entire buoy system can be made more stable; in addition, the connecting net rope 2 can block water flow, floating objects or other garbage, which is beneficial to reducing the speed of the water flow entering the offshore wind farm 3, and can also prevent the offshore floating garbage or the garbage in the water from damaging the offshore wind farm 3, playing a protective role for the offshore wind farm 3.

[0054] Furthermore, a positioning system is arranged on the observation device. By arranging a GPS positioning system or a Beidou positioning system on each detection buoy 1, the position of a single detection buoy 1 can be monitored to prevent the detection buoy 1 from being lost and unable to be retrieved due to force majeure or other accidents.

[0055] Furthermore, a flash light is provided on the buoy body 10. Through the flash light, nearby fishing boats or other ships can be warned. Especially at night, the ships can have enough time and distance to turn or turn around when they see the flash light, which can effectively protect the offshore wind farm 3.

[0056] The stabilizing component 11 includes a counterweight column 111. A ring plate 112 is disposed around the outer top end of the counterweight column 111. A plurality of bent ring plates 113 are sleeved on the outer side of the counterweight column 111. The plurality of bent ring plates 113 are arranged in parallel at intervals. A plurality of through holes 114 are equidistantly arranged on the bent ring plates 113. A plurality of second anchor ropes 115 are provided at the bottom of the ring plate 112. The second anchor ropes 115 are arranged corresponding to the through holes 114. The second anchor ropes 115 pass through the through holes 114 and are connected with a counterweight assembly 12.

[0057] The top of the counterweight column 111 is connected to the bottom of the buoy base 10 through a first anchor rope 101.

[0058] The top of the counterweight column 111 is connected to the bottom of the buoy base 10 through the first anchor rope 101, which can lower the center of the whole device, ensure the stability of the whole device, and prevent the buoy base 10 from tipping over or deviating seriously from the preset position under the impact of sea waves. By sleeving a plurality of bent ring plates 113 on the counterweight column 111, when the water flow passes through the bent ring plates 113, the bent ring plates 113 will move up and down along the movement track of the water flow, so that the plurality of bent ring plates 113 have a floating effect. Through the second anchor ropes 115 passing through the through holes 114 arranged at intervals of the bent ring plates 113, the up and down movement of the bent ring plates 113 can promote the up and down displacement of the counterweight column 111, and further can promote the counterweight column 111 to pull the first anchor rope 101 above it up and down, so as to reduce the excessive floating range of the buoy in the water surface direction under the action of the water flow, that is, to reduce the floating range of the buoy on the water surface through the up and down pulling effect. The bottom of the second anchor rope 115 is connected with a counterweight assembly 12, and the counterweight assembly 12 is used to control the displacement range of the counterweight column 111.

[0059] The counterweight assembly 12 includes a counterweight base column 121. A base plate 122 is provided at the bottom end of the counterweight base column 121. A bent mesh plate 123 is arranged around the base plate 122. A bent rod body 125 is provided on the side of the bent mesh plate 123 close to the base plate 122. The bent rod body 125 is connected to the side of the base plate 122.

[0060] A connection hole 124 is provided at the top end of the counterweight base column 121, and the connection hole 124 is used to connect with the second anchor rope 115.

[0061] The counterweight assembly 12 is connected with a second anchor rope 115, that is, multiple counterweight assemblies 12 are connected to and act on the counterweight column 111. The second anchor ropes 115 are equidistantly wound around the connecting ring plate 112, ensuring that the multiple counterweight assemblies 12 are evenly distributed around the counterweight column 111. Thus, it can cope with the displacement of the counterweight column 111 in all directions, control the displacement range of the detection buoy 1, improve the stability of the detection buoy 1, and further reduce the situation that the detection buoy moves out of the detection range due to large movement of the detection float caused by wind waves or other factors. In addition, by providing a base plate 122 at the bottom end of the counterweight column 111, the center of gravity of the counterweight assembly 12 can be lowered, and the contact between the counterweight assembly 12 and the seabed surface can be improved, enhancing the fixing effect, that is, improving the effect produced by the counterweight assembly 12. A bent net plate 123 is provided around the base plate 122. The bent net plate 123 is a multi-mesh structure with elasticity. When the counterweight assembly 12 sinks to the seabed, when the counterweight assembly 12 comes into contact with seabed structures such as reefs, the elastic deformation of the bent plate can be used to avoid damage to the reefs or other seabed structures. And when the bent net plate 123 undergoes elastic deformation, the sediment between the bent and extruded net plate and the base plate 122 is utilized, and this effect is used to slow down the movement of the counterweight assembly 12 on the seabed under the impact of water or other biological interferences. In addition, under the impact of water flow, the bent net plate 123 can fix part of the sediment brought by the water flow, thereby ensuring the fixing effect of the counterweight assembly 12.

[0062] Furthermore, the counterweight base column 121 is provided with leaf plates around it. The leaf plates connect the base plate 122 and the counterweight base column 121. The leaf plates can improve the strength of the counterweight assembly 12. At the same time, the leaf plates and the bent net plate 123 act together to form the effect of a fish reef, and the sediment and organisms accumulate on the counterweight assembly 12 to improve the counterweight effect.

[0063] Furthermore, the leaf plates are also connected to the bent rod bodies 125. The connection between the leaf plates and the bent rod bodies 125 improves the overall strength of the counterweight assembly 12 with the bent net plate 123.

[0064] The power supply assembly includes multiple solar panels 104 and an energy storage component. The multiple solar panels 104 are equidistantly arranged on the buoy base 10. The solar panels 104 are connected with an energy storage component, and the energy storage component is used to supply energy to the observation assembly.

[0065] When the solar panels 104 are powered, they will directly supply energy to the observation assembly through the energy storage component, providing energy for the observation assembly to ensure the normal observation of the observation assembly. When the solar panels 104 cannot supply power, such as at night or in bad weather, the energy storage component directly supplies power to the observation assembly to ensure the normal operation of the overall device.

[0066] Embodiment 2:

[0067] Figure 8 , 9 Schematically shows a long - term monitoring buoy system for an offshore wind farm according to another embodiment of the present invention. The difference from Embodiment 1 is that a brush 116 is provided on the side of the bent ring plate 113 close to the counterweight column 111.

[0068] With a brush 116 provided on the side of the bent ring plate 113 close to the counterweight column 111, the bent ring plate 113 will move up and down with the flow of the water body. The brush 116 can move with the bent plate so that the brush 116 contacts the counterweight column 111. Then, the surface of the counterweight column 111 and the second anchor rope 115 can be cleaned by the brush 116, which is beneficial to preventing the attachment of parasitic organisms on the counterweight column 111 and the second anchor rope 115, and preventing the counterweight column 111 or the second anchor rope 115 from being damaged or failing. In addition, through the setting of the brush 116, the overall contact area of the bent ring plate 113 with the water body can be made larger, improving the amplitude and effect of the up - and - down movement of the bent ring plate 113, and further improving the effect of the brush 116.

[0069] Embodiment 3:

[0070] Figure 12 , 11 Schematically shows a long - term monitoring buoy system for an offshore wind farm according to another embodiment of the present invention. The difference from Embodiment 1 is that:

[0071] A plurality of protective frames 13 are provided around the buoy body 10. At least one roller 131 is provided on the side of the protective frame 13 away from the buoy body 10. The roller 131 is rotatably connected to the protective frame 13, and a buffer space 132 is provided on the side of the protective frame 13 close to the buoy body 10.

[0072] With a buffer space 132 provided on the side of the protective frame 13 close to the buoy body 10, in the case where the buoy body 10 is impacted or collided, the impact force can be absorbed through the compression or elastic deformation of the buffer space 132, reducing the effect of the wave impact on the buoy, and playing a protective role. By providing at least one roller 131 on the side of the protective frame 13 away from the buoy body 10, and the roller 131 is rotatably connected to the protective frame 13, then the roller 131 can rotate with the flow of the water body. Under the rotation of the roller 131, the impact force generated by the transverse and longitudinal waves of the sea on the buoy body 10 can be reduced. The rolling of the roller 131 can also reduce the impact caused by accidentally approaching fishing boats or other vessels, playing a role in protecting the buoy body 10. In addition, the roller 131 can provide buoyancy to the detection buoy 1, preventing the detection buoy 1 from tipping over under the impact of large wind and waves.

[0074] Figure 12Schematically shows a long-term monitoring buoy system for an offshore wind farm according to another embodiment of the present invention. The difference from Embodiment 3 is as follows:

[0075] The roller 131 includes a transparent roller shaft 133 and a transparent roller shell 134. The inside of the transparent roller shell 134 is hollow, and a UV lamp 135 is provided inside the transparent roller shaft 133.

[0076] A UV lamp 135 is provided inside the roller shaft of the same name. By regularly turning on and off the UV lamp 135, it is possible to prevent organisms from attaching to the buoy base 10 and the transparent roller 131. The rotational movement of the light-transmitting roller 131 can reduce waves and also change the refraction of UV light to increase the range of attachment removal, ensuring that there are no attached aquatic organisms near the roller shaft rotation point and enabling the roller shaft to rotate normally.

[0077] Furthermore, the transparent roller is set as a light-transmitting structure. The transparent roller shaft 133 is preferably made of quartz glass structure.

[0078] Embodiment 5:

[0079] Figure 13 Schematically shows a long-term monitoring buoy system for an offshore wind farm according to another embodiment of the present invention. The difference from Embodiment 1 is as follows:

[0080] The connecting net rope 2 includes a barrier net body 21. A plurality of barrier floats 22 are provided on the barrier net body 21. The barrier net body 21 is connected to the buoy base 10 through a third anchor rope.

[0081] By providing the barrier net body 21, the speed of water entering the offshore wind farm 3 can be reduced, and at the same time, the detection accuracy of the measurement component for water can be improved, ensuring the accuracy of the overall device. In addition, by providing the barrier floats 22, the impact of offshore floating objects on the barrier net body 21 can be reduced, and the situation where the barrier net body 21 is damaged due to the impact of floating objects or other garbage on the barrier net body 21 can be reduced. The barrier floats 22 can provide a certain buoyancy, that is, part of the barrier net body 21 floats on the water surface, enabling the barrier net body 21 to collect debris or garbage floating on the water surface or flowing with the underwater current, ensuring the safety of the inner waters of the offshore wind farm 3.
