Description

Technical Field

[0001] The utility model relates to the technical field of offshore wind power, and in particular to a corrosion monitoring device for offshore wind power and offshore wind power. Background Art

[0002] Offshore wind power refers to wind turbines using offshore wind resources to generate electricity. It is a sustainable new energy source that is beneficial to reducing the use of fossil energy and is in line with environmental protection concepts. Since sea breezes are highly corrosive, they can easily cause corrosion and rust on wind turbines. Therefore, offshore wind power corrosion monitoring devices are needed to monitor wind turbines.

[0003] In the prior art, a Chinese utility model patent with authorization announcement number CN218911547U discloses an offshore wind power corrosion monitoring device, which includes a first offshore wind power foundation column (i.e., an offshore wind power base column), a second semi-rectangular tube, and a first offshore wind power corrosion monitoring instrument, and a support shaft is threadedly connected to one side of the first semi-rectangular tube. The offshore wind power corrosion monitoring device, through the arrangement of the second supporting square rod and the limit ring, enables the offshore wind power corrosion monitoring device to have the effect of increasing the stability of the support plate during rotation, and achieves the purpose of convenient installation through the coordinated arrangement of the support shaft, the first semi-rectangular tube, and the first supporting long plate. Through the arrangement of the fourth limit long plate, the offshore wind power corrosion monitoring device has the effect of preventing the sixth supporting long plate from sliding out of the first supporting rectangular tube, and achieves the purpose of convenient monitoring through the coordinated arrangement of the first supporting rectangular tube, the second supporting long plate, and the sixth supporting long plate.

[0004] However, in actual use, it is sometimes necessary to monitor corrosion at different circumferential positions of the offshore wind turbine column.

At the same time, since the wind turbine corrosion monitor is fixed in position, its position is not easy to change when facing continuous strong winds coming from the positive direction, and it is easily affected by the wind, causing the wind turbine corrosion monitor to loosen and fall off.

DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application: Specific embodiment 1:

[0045] refer to Figures 1 to 7 An offshore wind power of the utility model includes an offshore wind power column 1 and a wind turbine set (not shown in the figure) arranged on the offshore wind power column 1, wherein a corrosion monitoring device for offshore wind power (hereinafter referred to as the corrosion monitoring device) is arranged on the offshore wind power column 1.

[0046] In this embodiment, the offshore wind power column 1 is a square column with a square cross section. Figure 1 , 2 As shown, the corrosion monitoring device includes a mounting sleeve 2 and a corrosion monitor 8, wherein the inner hole of the mounting sleeve 2 is a square hole adapted to the offshore wind power column 1, and the mounting sleeve 2 is integrally sleeved and fixed on the outer peripheral surface of the offshore wind power column 1.

[0047] A first annular groove 4 is circumferentially arranged on the mounting sleeve 2, a slider 6 is slidably arranged in the first annular groove 4, one end of the slider 6 facing away from the first annular groove 4 is fixedly connected to the corrosion monitor 8, and a monitoring head 12 is arranged on the side of the corrosion monitor 8 facing the mounting sleeve 2. A plurality of monitoring ports 11 adapted to the monitoring head 12 are spaced apart circumferentially on the mounting sleeve 2, the monitoring head 12 is used to extend into the monitoring port 11 and abut against the offshore wind power base column 1, and an anti-slip structure is also provided on the mounting sleeve 2, and the anti-slip structure is used to prevent the slider 6 from slipping out of the first annular groove 4.

[0048] Specifically, in this embodiment, the mounting sleeve 2 includes a sleeve body 21, which is a square tube. Two mounting discs 3 are arranged vertically at intervals on the sleeve body 21, and a first annular chute 4 is provided on the outer circumference of the mounting disc 3, and the axis of the first annular chute 4 extends vertically.

[0049] A slider 6 is slidably disposed in the first annular slot 4 of each mounting disc 3. Figure 2 , 6 As shown, a support rod 7 extending radially outward is fixedly provided at one end of the slider 6 facing away from the first annular slide groove 4, and the corrosion monitor 8 is arranged as a whole between the two mounting discs 3, and a vertically extending connecting plate 18 is respectively provided at the upper and lower ends of the corrosion monitor 8. The position of the connecting plate 18 corresponds to the support rod 7 on the corresponding side, and the end of the support rod 7 facing the connecting plate 18 is fixedly connected to the corresponding connecting plate 18 by screws, so as to fix the slider 6 and the corrosion monitor 8.

[0050] In this embodiment, if Figure 2 As shown, the monitoring port 11 is arranged between the two mounting discs 3, and a monitoring port 11 is arranged on each of the four peripheral surfaces of the casing body 21, and the size of the monitoring port 11 is adapted to the size of the monitoring head 12. In this way, on the one hand, the corrosion conditions of different peripheral surfaces of the offshore wind power column 1 can be monitored by inserting the monitoring head 12 into different monitoring ports 11, and on the other hand, the monitoring port 11 can be used to limit the position of the monitoring head 12 to avoid the position of the corrosion monitor 8 from being offset, thereby ensuring the monitoring accuracy of the monitoring head 12.

[0051] Through the above-mentioned arrangement, by pushing the corrosion monitor 8, under the action of the slider 6, the corrosion monitor 8 can be moved along the track of the first annular chute 4. On the one hand, it is convenient to change the circumferential position of the corrosion monitor 8, and it is not necessary to disassemble the corrosion monitoring device as a whole, so that corrosion monitoring can be performed on other circumferential positions of the offshore wind power column 1, thereby improving work efficiency and reducing work difficulty. On the other hand, in the face of a continuous sea breeze environment, by pushing the corrosion monitor 8 to move in the first annular chute 4, the offshore wind power column 1 can be used to shield the corrosion monitor 8, reducing the impact of the sea breeze on the corrosion monitor 8, which is conducive to reducing the loss of the corrosion monitor 8 and increasing its service life.

[0052] In this embodiment, preferably, Figure 4 , 5 As shown, the anti-slip structure includes a second annular chute 5 arranged on the upper and lower groove walls of the first annular chute 4, the second annular chute 5 is arranged concentrically with the first annular chute 4, and the depth of the second annular chute 5 is along the axial direction of the first annular chute 4 (i.e., Figure 5 As shown in the vertical direction. Figure 6As shown, one end of the slider 6 that penetrates into the first annular groove 4 is provided with a protrusion 61 that is adapted to the second annular groove 5, and two protrusions 61 are symmetrically arranged in the longitudinal direction. The two protrusions 61 are respectively slidably arranged in the second annular groove 5 on the corresponding sides. The slider 6 can be stopped in the first annular groove 4 by the protrusion 61, and the slider 6 is restricted from escaping from the first annular groove.

[0053] In this embodiment, a countersunk hole (not shown in the figure) adapted to the protrusion 61 is provided at the position of the slider 6 corresponding to the protrusion 61, and a limiting spring is provided in the countersunk hole. The lower end of the protrusion 61 penetrates into the countersunk hole and is connected to the upper end of the limiting spring. During actual installation, the protrusion 61 is first squeezed to make the protrusion 61 sink into the countersunk hole, and the slider 6 is pushed radially into the first annular groove 4, and the slider 6 is continuously pushed into the first annular groove 4. When the protrusion 61 enters the second annular groove 5, the protrusion 61 automatically bounces into the second annular groove 5 under the action of the limiting spring, thereby installing the slider 6 in the first annular groove 4.

[0054] In this embodiment, preferably, an arcuate surface (not shown in the figure) is provided at one end of the slider 6 facing the first annular groove 4, and the arcuate surface fits snugly with the inner wall of the first annular groove 4, thereby increasing the contact area between the slider 6 and the first annular groove 4 and improving the sliding stability.

[0055] In this embodiment, the corrosion monitor 8 is further provided with a linear drive mechanism, which is connected to the monitoring head 12 and is used to drive the monitoring head 12 to enter and exit the monitoring port 11 .

[0056] Specifically, Figure 2 As shown, the linear drive mechanism includes a telescopic cylinder 17 disposed between the monitoring head 12 and the corrosion monitor 8, the telescopic end of the telescopic cylinder 17 is connected to the monitoring head 12, and the other end is connected to the corrosion monitor 8, so that the monitoring head 12 can be remotely controlled to enter and exit the monitoring port 11 by controlling the telescopic movement of the telescopic cylinder 17. And when the telescopic cylinder 17 is at the extreme contraction position, the end of the monitoring head 12 facing the monitoring port 11 is located outside the circumscribed circular contour line of the mounting sleeve 2, so that when the corrosion monitor 8 is pushed to rotate along the first annular chute 4, the monitoring head 12 will not interfere with the mounting sleeve 2.

[0057] In this embodiment, the corrosion monitoring device also includes a wind measuring device and a control module. The wind measuring device includes an anemometer. The anemometer and the telescopic cylinder 17 are electrically connected to the control module. In actual use, when the anemometer tests that the corrosion monitor 8 is in a frontal windward state, the telescopic cylinder 17 is controlled to retract by the control module. After that, the corrosion monitor 8 automatically slides along the first annular slide 4 under the action of the sea breeze until it slides to the monitoring port 11 in the leeward position. The control module controls the monitoring head 12 to extend to the monitoring port 11. At this time, the offshore wind power base column 1 blocks the corrosion monitor 8. In this way, the sea breeze can be used to automatically drive the corrosion monitor 8 to slide to the leeward position, thereby improving practicality.

[0058] Of course, in other embodiments, when the monitoring head 12 of the corrosion monitor 8 does not reach the monitoring port 11 on the back side under the action of the sea breeze, the position of the corrosion monitor 8 can be manually adjusted by the staff to align the monitoring head 12 with the corresponding monitoring port 11. In other embodiments, when facing the sea breeze environment, the staff can control the telescopic cylinder 17 to retract on site, and then directly manually drive the corrosion monitor 8 to slide to the monitoring port 11 on the windward side.

[0059] In other embodiments, the casing body 21 can be a circular tube structure, and the inner hole of the circular tube structure is adapted to the outer peripheral surface of the offshore wind power column 1. In this case, the shape of the monitoring port 11 can be adapted to the sliding route of the corrosion monitor 8, that is, the monitoring port 11 is an arc-shaped port. At this time, under the action of the sea breeze, the monitoring head 12 is separated from the offshore wind power column 1 by contracting the telescopic cylinder 17, and the monitoring head 12 can slide directly within the range of the monitoring port 11. When the monitoring head 12 slides to the leeward position, the telescopic cylinder 17 extends, and the monitoring head 12 abuts against the offshore wind power column 1 again. In addition, in order to increase practicality, the arc of the arc-shaped port can be made as close to 360 degrees as possible while meeting the strength requirements, so as to avoid the monitoring head 12 not accurately reaching the monitoring port 11 at the leeward position when sliding under the action of the sea breeze in actual use. At this time, in order to increase stability, the upper and lower sides of the casing body 21 can be fixed on the offshore wind power column 1.

[0060] In this embodiment, preferably, the installation sleeve 2 is slidably arranged on the offshore wind power column 1, and the corrosion monitoring device further comprises a lifting mechanism 10, which is used to drive the installation sleeve 2 to rise and fall along the offshore wind power column 1. The monitoring position of the corrosion monitor 8 can be adjusted in the vertical direction to expand the monitoring range and improve the practicality.

[0061] In this embodiment, the lifting mechanism 10 includes an electric roller 102 and a connecting rope 103, wherein the electric roller 102 is used to be fixed on the offshore wind turbine base 1, and the electric roller 102 is located above the mounting sleeve 2 as a whole, one end of the connecting rope 103 is wrapped around the electric roller 102, and the other end is connected to the mounting sleeve 2.

[0062] Specifically, support plates 101 are welded and fixed on both sides of the top of the offshore wind power column 1, and a motor roller 102 is fixed on each of the two support plates 101, and the lower ends of the two connecting ropes 103 are respectively connected to the upper end surface of the upper mounting disc 3. The upper end of the casing body 21 extends out of the upper mounting disc 3, and a bracket 106 extending outward is provided at the position of the casing body 21 corresponding to the connecting rope 103, and a through hole adapted to the connecting rope 103 is provided on the bracket 106, and the connecting rope 103 passes through the through hole, and the through hole on the bracket 106 is used to guide the traction of the connecting rope 103.

[0063] In this embodiment, preferably, a fixing hole 16 is provided on the installation sleeve 2, and the installation sleeve 2 is fixed to the offshore wind power column 1 through a fixing member provided in the fixing hole 16. Specifically, a plurality of limiting holes 104 are provided on the offshore wind power column 1 at intervals along the vertical direction on one side corresponding to the fixing hole 16, and the plurality of limiting holes 104 are arranged in an array with equal spacing along the vertical direction.

[0064] The fixing part includes a pneumatic telescopic cylinder 105, the cylinder body of the pneumatic telescopic cylinder 105 is fixedly installed at the position of the installation sleeve 2 in the fixing hole 16, and the telescopic end of the pneumatic telescopic cylinder 105 passes through the fixing hole 16 and extends to the inside of the limiting hole 104. In this way, the installation sleeve 2 can be fixed on the offshore wind power base 1 by pushing the telescopic end of the pneumatic telescopic cylinder 105 into the limiting hole 104.

[0065] In actual use, when the monitoring position of the corrosion monitor 8 in the vertical direction needs to be adjusted, the pneumatic telescopic cylinder 105 is first contracted, and its telescopic end is separated from the limiting hole 104, and then the lifting mechanism 10 is started to adjust the vertical position of the corrosion monitor 8. When the next designated position is reached and the pneumatic telescopic cylinder 105 is aligned with the limiting hole 104 at the position, the pneumatic telescopic cylinder 105 is extended, and its telescopic end is deeply inserted into the limiting hole 104 to complete the vertical position adjustment. In this way, the vertical position of the corrosion monitor 8 can be automatically adjusted.

[0066] In this embodiment, preferably, the corrosion monitoring device also includes a drying component 9 arranged below the mounting sleeve 2, the drying component 9 includes a bellows 91 fixedly arranged at the lower part of the offshore wind power foundation, the bellows 91 is provided with an air inlet and an air outlet, and the air outlet is arranged correspondingly at the lower part of the corrosion monitor 8, the drying component 9 also includes a fan 94 and a heater, the heater is used to heat and dry the air, and the fan 94 is used to blow the heated and dried air toward the corrosion monitor 8.

[0067] Specifically, the side of the wind box 91 facing away from the offshore wind power column 1 is fixedly connected with an air inlet pipe 92, and the heating element is an electric heating pipe 93. A plurality of electric heating pipes 93 are arranged at equal intervals in a circular array in the inner cavity of the air inlet pipe 92. The end of the air inlet pipe 92 facing away from the wind box 91 is an air inlet, and a filter cover 910 is installed at the air inlet by threads, and a sponge 99 is clamped inside the filter cover 910, so that the sponge 99 can absorb moisture in the air and heat the air through the electric heating pipe 93.

[0068] In this embodiment, the fan 94 is arranged on the upper side of the inner cavity of the wind box 91, and the air outlet of the wind box 91 is arranged in the direction. The upper end of the fan 94 is the air outlet end, and the air outlet end extends upward and extends out of the air outlet of the wind box 91. An air guide 95 is sealed and plugged at the air outlet end of the fan 94, and a fixing ring 98 is sleeved on the upper end of the air guide 95. A magnet 97 is fixed to the outer wall of the fixing ring 98, and the magnet 97 can be adsorbed on the offshore wind power base column 1 or the installation sleeve 2 to fix the upper end position of the air guide 95.

[0069] The upper end of the air duct 95 is also threadedly connected with an air outlet 96, which is arranged at the lower position of the corrosion monitor 8. In this way, the outside air can be drawn into the bellows 91 through the fan 94 and the air inlet pipe 92, and some moisture and debris in the air can be filtered through the sponge 99 and the filter cover 910. Under the action of the electric heating tube 93, the air can be heated and the moisture can be removed. The fan 94 and the air duct 95 then discharge the hot air to the outside, and the hot air is guided to the corrosion monitor 8 by the air outlet 96, so that the corrosion monitor 8 can be dried, which is beneficial to reducing the loss of the corrosion monitor 8.

Reinforcement plates 15 are welded around the top end surface of the bottom plate 13, and the reinforcement plates 15 are welded and fixed to the outer wall of the offshore wind power column 1. The reinforcement plates 15 can improve the support effect of the offshore wind power column 1, and the connection holes 14 can be used to connect the bottom plate 13 to the ground.

[0071] How this application works:

[0072] When in use, an external power supply is used and electric wires are used to connect the power supply to the electric roller 102, the fan 94, the corrosion monitor 8, etc. to achieve a power supply effect. The corrosion monitor 8 is pushed by manpower or wind power. Under the action of the slider 6, the corrosion monitor 8 can be moved along the trajectory of the first annular slide groove 4. The offshore wind power base 1 is used to shield the corrosion monitor 8 to reduce the impact of the sea breeze on the corrosion monitor 8.
