Description

Technical Field

[0001] The invention relates to the technical field of marine equipment antifouling, and in particular to a movable in-situ electrolysis antifouling device with an offshore steel structure. Background Art

[0002] The problem of marine biofouling is a global problem. Marine biofouling can cause changes in the deadweight of marine equipment (especially offshore steel structures), resulting in different deadweights in different areas of the same marine equipment. At the same time, marine biofouling can change the physical and chemical properties of the surface of marine equipment materials, causing local corrosion or perforation corrosion of marine equipment. When encountering typhoons or other extreme weather, it is likely to cause marine equipment to tilt, and even topple in severe cases. Therefore, marine biofouling can significantly affect the service performance, service life and maintenance cost of marine equipment.

[0003] For offshore wind turbine piles and other steel structures, since they are in an open seawater environment, they are inevitably affected by marine biofouling. For steel structures immersed in seawater, the commonly used anti-fouling technologies include:

[0004] Physical removal means: refers to the use of external force and mechanical devices to remove fouling organisms on the surface of the pile legs. People need to go into the water regularly for anti-fouling treatment, or operate through remote equipment. The effect is obvious, but it cannot prevent the occurrence of biological fouling. It is only a post-treatment of the fouling problem, and the cost of each treatment is high.

[0005] Coating antifouling technology: refers to coating the surface of marine structures with antifouling paint, using the toxic substances released in the paint to inhibit the attachment and growth of fouling organisms. However, the antifouling period of antifouling paint is short and needs to be reapplied regularly. In addition, some antifouling paints will pollute the marine environment, deform marine organisms, and cause great harm to humans themselves.

[0006] Electrolytic anti-fouling technology: mainly electrolytic seawater anti-fouling technology, which uses electrolysis of seawater to produce sodium hypochlorite (NaClO), hypochlorous acid (HClO), chlorine (Cl 2 ) and other effective chlorine to kill marine organisms, which can kill all kinds of marine organisms, with a wide range of treatment capacity and no pollution. However, since the steel structure of the offshore wind power foundation is generally located in the wave splash zone, tidal range zone, full immersion zone and sea mud zone, and the existing electrolytic anti-fouling devices are all fixed (that is, the position of the electrolytic anti-fouling device is fixed), an electrolytic cell can only be electrolyzed at one position, and the generated sodium hypochlorite can only be diffused in a specific position, and the electrolytic cell cannot be arranged in the tidal range zone (because when the tide is low, the electrolytic cell may be exposed on the sea surface, and there is no seawater in the electrolytic cell to electrolyze, which will cause the electrolytic cell to short-circuit, making the electrolytic cell unable to work. During this period, the steel pile legs cannot be protected, and marine organisms can easily attach during this period), thereby affecting the anti-fouling efficiency and scope of application of the electrolytic anti-fouling device. Summary of the invention

[0007] The purpose of the present invention is to provide an offshore steel structure movable in-situ electrolytic anti-fouling device, the electrolytic cell can be moved up and down according to the change of tide, so that the electrolytic cell can always be below the sea level, and the normal operation of the electrolytic cell will not be affected by low tide or high tide, which solves the problem that the electrolytic anti-fouling device cannot be applied to tidal range areas, and improves the anti-fouling efficiency and application range of the electrolytic anti-fouling device.

[0025] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] The terms "first", "second", "third", "fourth" and the like (if any) in the description and claims of the present invention are used to distinguish similar objects and are not necessarily used to describe a particular sequence or order.

[0027] like Figures 1 to 3As shown, the movable in-situ electrolytic antifouling device for offshore steel structures provided in the embodiment of the present invention is used for electrolytic antifouling of offshore steel structures 6. The offshore steel structure 6 may be an offshore platform, an offshore wind power generation device, etc. The steel pile legs of the offshore steel structure 6 are generally immersed in seawater and affected by marine biological fouling, so electrolytic antifouling is required.

[0028] The movable in-situ electrolytic anti-fouling device for offshore steel structure comprises an electrolytic device 1, a traction device 2, a control device 3 and a liquid level meter 4. The electrolytic device 1 comprises an electrolytic cell 11, which is used to be arranged in the seawater near the offshore steel structure 6 (the electrolytic cell 11 is immersed in the seawater). The electrolytic cell 11 can electrolyze the seawater to produce effective chlorine (effective chlorine includes sodium hypochlorite (NaClO), hypochlorous acid (HClO), chlorine gas (Cl 2 ) etc.), to kill marine microorganisms near the marine steel structure 6, thereby preventing the marine steel structure 6 from being fouled in real time. The control device 3 and the traction device 2 are used to be arranged on the marine steel structure 6, the traction device 2 is connected to the electrolytic cell 11, and the traction device 2 is used to pull the electrolytic cell 11 up and down; the liquid level meter 4 is used to detect the liquid level of the seawater near the marine steel structure 6, and the control device 3 is connected to the liquid level meter 4 and the traction device 2 at the same time. The control device 3 is used to control the traction device 2 to pull the electrolytic cell 11 up and down according to the seawater liquid level value measured by the liquid level meter 4, so that the electrolytic cell 11 is always located in the seawater near the marine steel structure 6 (for example, the electrolytic cell 11 is always kept 0.5 meters below the seawater surface).

[0029] Specifically, during operation, the liquid level of the seawater near the marine steel structure 6 is detected by the liquid level meter 4, so as to determine the height position of the sea level; the liquid level meter 4 transmits the measured seawater liquid level value to the control device 3, and the control device 3 controls the traction device 2 to pull the electrolytic cell 11 upward or downward after performing data analysis and calculation: that is, at high tide, the sea level rises, the seawater liquid level increases, and the traction device 2 pulls the electrolytic cell 11 upward; at low tide, the sea level drops, the seawater liquid level decreases, and the traction device 2 pulls the electrolytic cell 11 downward, so that the electrolytic cell 11 is always immersed in the seawater (for example, if the seawater liquid level increases by 1 meter, the traction device 2 pulls the electrolytic cell 11 upward by 1 meter; if the seawater liquid level decreases by 1 meter, the traction device 2 pulls the electrolytic cell 11 downward by 1 meter).

[0030] Specifically, the movable in-situ electrolytic anti-fouling device for offshore steel structures of this embodiment detects the liquid level of seawater near the marine steel structure 6 by setting a liquid level meter 4, and sets a traction device 2 to traction the electrolytic cell 11 to move up and down; the control device 3 is used to control the traction device 2 to traction the electrolytic cell 11 to move up and down according to the seawater liquid level value measured by the liquid level meter 4, so that the electrolytic cell 11 is always located in the seawater near the marine steel structure 6, that is, the electrolytic cell can move up and down according to the change of tide, so that the electrolytic cell can always be below the sea level, and the normal operation of the electrolytic cell will not be affected by low tide or high tide, which solves the problem that the electrolytic anti-fouling device cannot be applied to the tidal range area, and improves the anti-fouling efficiency and application range of the electrolytic anti-fouling device. Moreover, since the electrolytic cell 11 is directly immersed in the seawater, the in-situ electrolytic anti-fouling device has a simple structure, high electrolysis efficiency, and good killing effect. At the same time, the effective chlorine produced by the electrolytic cell 11 is within a controllable concentration range, which will only have a strong inhibitory growth and killing effect on marine organisms near the marine steel structure 6. Through the diffusion of ocean currents, it will not affect the normal growth of marine organisms outside the marine steel structure 6 and will not pollute the environment.

[0031] Furthermore, if Figure 1 As shown, in this embodiment, the traction device 2 includes a driving device 21 and a connecting device 22, and the driving device 21 is used to be fixed on the marine steel structure 6. The driving device 21 is located above the electrolytic cell 11, the driving device 21 is located above the sea level and the driving device 21 is arranged away from the sea level (that is, the driving device 21 is not arranged in the sea water to prevent the sea water from corroding the driving device 21 and preventing the driving device 21 from short-circuiting), and the driving device 21 is connected to the electrolytic cell 11 through the connecting device 22, and the driving device 21 is used to drive the connecting device 22 to move, thereby driving the electrolytic cell 11 to move up and down.

[0032] Furthermore, if Figure 1 As shown, in this embodiment, the driving device 21 is a driving motor, and the connecting device 22 includes a fixed base 221, a connecting shaft 222, a pulley 223 and a traction rope 224. The fixed base 221 is used to be fixed on the marine steel structure 6, and the connecting shaft 222 is rotatably connected to the fixed base 221, and the connecting shaft 222 is connected to the output end of the driving motor; the pulley 223 is fixedly connected to the connecting shaft 222, one end of the traction rope 224 is fixedly connected to the pulley 223, and the other end of the traction rope 224 is fixedly connected to the electrolytic cell 11, and the traction rope 224 can be wound around the pulley 223 during the rotation of the pulley 223; the driving motor is used to drive the connecting shaft 222 and the pulley 223 to rotate, thereby controlling the winding amount of the traction rope 224, and then driving the electrolytic cell 11 to move up and down.

[0033] Specifically, during operation, the driving motor drives the connecting shaft 222 to rotate, and the rotation of the connecting shaft 222 drives the pulley 223 to rotate, and the rotation of the pulley 223 changes the winding amount of the traction rope 224, thereby driving the electrolytic cell 11 to move up and down: when the pulley 223 rotates in a certain direction, the winding amount of the traction rope 224 increases (that is, more traction rope 224 is wound on the pulley 223, and the length of the suspended traction rope 224 is reduced), thereby causing the electrolytic cell 11 to move upward; when the pulley 223 rotates in the opposite direction, the winding amount of the traction rope 224 decreases (that is, the length of the traction rope 224 wound on the pulley 223 is reduced, and the length of the suspended traction rope 224 is increased), thereby causing the electrolytic cell 11 to move downward (that is, the traction device 2 is similar to the working principle of a winch).

[0034] When the seawater level changes, the level meter 4 feeds back a signal to the control device 3, and the control device 3 sends a command to the drive motor according to the system calculation result, and the drive motor drives the pulley 223 to rotate clockwise or counterclockwise to a certain distance; when the drive motor completes the rotation, the signal is fed back to the control device 3 again, and the drive motor stops.

[0035] Furthermore, if Figure 1 As shown, in this embodiment, the number of pulleys 223 and traction ropes 224 are both two, the two traction ropes 224 are respectively connected to the two pulleys 223, the connecting shaft 222 is simultaneously connected to the two pulleys 223 (i.e., the connecting shaft 222 strings the two pulleys 223 together), and the two traction ropes 224 are respectively connected to the two ends of the electrolytic cell 11. During operation, the driving motor drives the connecting shaft 222 to rotate, and the connecting shaft 222 drives the two pulleys 223 to rotate simultaneously, at which time the two traction ropes 224 are synchronously extended and retracted, so that the two ends of the electrolytic cell 11 remain horizontal when moving up and down.

[0036] like Figure 4 As shown, in another embodiment, the driving device 21 is a driving motor, and the connecting device 22 includes a fixed base 221, a connecting shaft 222, a pulley 223 and a traction rope 224. The fixed base 221 is used to be fixed on the marine steel structure 6, and the connecting shaft 222 is rotatably connected to the fixed base 221, and the connecting shaft 222 is connected to the output end of the driving motor; the pulley 223 is fixedly connected to the connecting shaft 222, one end of the traction rope 224 is fixedly connected to the pulley 223, and the other end of the traction rope 224 is fixedly connected to the fixed base 221 after bypassing the electrolytic cell 11, and the traction rope 224 can be wound around the pulley 223 during the rotation of the pulley 223; the driving motor is used to drive the connecting shaft 222 and the pulley 223 to rotate, thereby controlling the winding amount of the traction rope 224, and then driving the electrolytic cell 11 to move up and down.

[0037] Specifically, Figure 4 The working principle of the structure shown is similar to Figure 1The working principle of the structures shown is basically the same, that is, the distance of the electrolytic cell 11 moving up and down is controlled by controlling the winding amount of the traction rope 224. The difference is that Figure 4 The middle electrolytic cell 11 is not fixedly connected to the traction rope 224. When the traction rope 224 moves up and down, the electrolytic cell 11 can move relative to the traction rope 224 (that is, the electrolytic cell 11 is equivalent to a movable pulley), thereby allowing the electrolytic cell 11 to move up and down.

[0038] like Figure 5 As shown, in another embodiment, the driving device 21 is a lifting device, and the connecting device 22 includes a connecting rod 225 and a lifting rod 226. The connecting rod 225 is connected to the lifting device, one end of the lifting rod 226 is connected to the connecting rod 225, and the other end of the lifting rod 226 is connected to the electrolytic cell 11; the lifting device 21 is used to drive the connecting rod 225 and the lifting rod 226 to move up and down, thereby driving the electrolytic cell 11 to move up and down. The lifting device can be, for example, a linear bearing module, a gear rack module, and other devices.

[0039] Furthermore, in this embodiment, the offshore steel structure movable in-situ electrolysis anti-fouling device further includes a power cabinet (not shown, the power cabinet includes a rectifier for rectifying AC power into DC power), the power cabinet is electrically connected to the electrolytic cell 11 and is used to supply power to the electrolytic cell 11. The power cabinet can periodically and intermittently supply power to the electrolytic cell 11, and by periodically and intermittently supplying power according to the pollution situation of the marine organisms, it can not only ensure that the effective chlorine concentration can achieve a sufficient killing effect, but also save power consumption.

[0040] Furthermore, if Figure 1 As shown, in this embodiment, the offshore steel structure movable in-situ electrolysis anti-fouling device further includes a track 5, which is used to be fixed on the marine steel structure 6; the track 5 is arranged to extend vertically, and the electrolytic cell 11 is connected to the track 5, and the electrolytic cell 11 can move up and down along the track 5. By providing the track 5, the electrolytic cell 11 can move up and down along the track 5, which can avoid the displacement of the moving direction of the electrolytic cell 11, and can prevent the electrolytic cell 11 from falling off, thereby improving the operation stability of the electrolytic cell 11.

[0041] Furthermore, if Figure 1 As shown, in this embodiment, the track 5 is an integral concave structure to prevent the electrolytic cell 11 from detaching from the track 5. Figure 6 As shown, in another embodiment, the track 5 is composed of two half tracks of a C-shaped structure. Figure 7 As shown, in another embodiment, the track 5 is composed of two half tracks of L-shaped structures. Of course, in other embodiments, the track 5 can also be other shape structures.

[0042] Furthermore, if Figure 1 and Figure 2As shown, in this embodiment, the electrolysis device 1 further includes a fixed plate 12 , the electrolytic cell 11 is fixedly connected to the fixed plate 12 , and the traction device 2 is connected to the fixed plate 12 ; the fixed plate 12 is disposed in the track 5 and can move up and down along the track 5 .

[0043] Furthermore, if Figure 2 As shown, in this embodiment, the electrolytic cell 11 can be a circular or square structure. The electrolytic device 1 also includes a protective cover 13, which is sleeved outside the electrolytic cell 11. The protective cover 13 is used to prevent marine debris or seaweed in seawater from adhering to the electrolytic cell 11, thereby increasing the service life of the electrolytic cell 11.

[0044] Furthermore, if Figure 1 and Figure 2 As shown, in this embodiment, the electrolysis device 1 also includes a baffle 14, which is connected to the electrolytic cell 11. The baffle 14 is located on the side of the electrolytic cell 11 close to the marine steel structure 6 (that is, the baffle 14 is located between the electrolytic cell 11 and the marine steel structure 6). The baffle 14 is used to prevent the effective chlorine generated by electrolysis in the electrolytic cell 11 from directly contacting the marine steel structure 6 (that is, the baffle 14 can play a baffle role to prevent the effective chlorine generated by electrolysis in the electrolytic cell 11 from directly flowing to the marine steel structure 6), thereby protecting the marine steel structure 6 from corrosion by high concentration of sodium hypochlorite.

[0045] Furthermore, in this embodiment, the number of electrolytic cells 11 can be calculated based on the area of ​​the marine steel structure 6 that needs to be protected.

[0046] Furthermore, in this embodiment, the anode (not shown) in the electrolytic cell 11 is made of titanium coated with precious metal oxide, and the cathode (not shown) is a titanium plate.

[0047] Furthermore, in this embodiment, the control device 3 is a control cabinet.

[0048] The movable in-situ electrolytic anti-fouling device for offshore steel structures provided by the embodiment of the present invention detects the liquid level of seawater near the marine steel structure 6 by setting a liquid level meter 4, and sets a traction device 2 to traction the electrolytic cell 11 to move up and down; the control device 3 is used to control the traction device 2 to traction the electrolytic cell 11 to move up and down according to the value of the seawater liquid level measured by the liquid level meter 4, so that the electrolytic cell 11 is always located in the seawater near the marine steel structure 6, that is, the electrolytic cell can move up and down according to the change of tide, so that the electrolytic cell can always be below the sea level, and the normal operation of the electrolytic cell will not be affected by low tide or high tide, which solves the problem that the electrolytic anti-fouling device cannot be applied to tidal range areas, and improves the anti-fouling efficiency and application range of the electrolytic anti-fouling device. Moreover, since the electrolytic cell 11 is directly immersed in seawater, the in-situ electrolytic anti-fouling device has a simple structure, high electrolysis efficiency, and good killing effect. At the same time, the effective chlorine produced by the electrolytic cell 11 is within a controllable concentration range, which will only have a strong inhibitory growth and killing effect on marine organisms near the marine steel structure 6. Through the diffusion of ocean currents, it will not affect the normal growth of marine organisms outside the marine steel structure 6 and will not pollute the environment.

[0049] Examples:

[0050] The electrolytic anti-fouling device of the single pile foundation of a certain offshore wind power test project mainly includes an electrolytic cell 11, a track 5, a liquid level meter 4, a control cabinet (control device 3), and a traction device 2 (including a drive motor, a fixed base 221, a connecting shaft 222, a pulley 223, and a traction rope 224, etc.). The diameter of the protected single pile foundation is 1.8 meters, the tidal range is 4 meters, the high tide level is 3.5 meters, and the low tide level is -0.5 meters. The track 5 is designed to be 5 meters long, with a total of 2 tracks. The electrolytic cell 11 is always kept 0.5 meters below the seawater level. After the electrolytic cell 11 is installed in the project, the initial position of the electrolytic cell 11 is set in the control cabinet. The control cabinet will adjust the height of the electrolytic cell 11 in real time when the tide changes according to the calculation formula.
