Technical Field

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

[0002] Offshore wind power refers to the use of offshore wind resources to generate electricity by wind turbines. Since the offshore wind turbine piles of wind turbines are exposed to seawater immersion and corrosion for a long time, it is necessary to monitor the corrosion of the piles to understand the corrosion status of the offshore wind turbine piles and predict the life of the piles.

[0003] When existing offshore wind power corrosion monitoring devices are installed on offshore wind power monopiles, they are mostly installed by putting a regular U-shaped fixing frame on the outside of the monopile, then installing a fixing plate on the fixing frame to close its opening, and using bolts to connect and fix the fixing frame and the fixing plate to achieve installation.

[0004] However, when installing the above-mentioned monitoring device, the fixing frame and the fixing plate are separate, and the installation operation is cumbersome and not convenient enough. Secondly, the offshore wind power single pile is subjected to the impact of seawater for a long time, which is prone to vibration. The bolts are easy to loosen during long-term use, and the installation of the monitoring device is not firm enough. Utility Model Content

[0012] Furthermore, the limiting mechanism also includes a spring installed between the fixing rod and the bottom wall of the fixing hole.

[0013] Furthermore, the height of the inclined block is greater than the diameter of the limiting rod, so that the connecting end of the inclined block and the limiting rod is stepped, and under the force generated by the deformation of the spring, the edge of the bottom wall of the through hole abuts against the connecting end of the inclined block and the limiting rod.

[0014] Furthermore, a mounting plate is fixedly connected to the end of the mounting frame away from the fixing groove, a screw rod is vertically arranged on the mounting plate, a sleeve is installed at the lower end of the screw rod, a corrosion monitor is fixedly connected to the outer circumferential surface of the sleeve, and a driving assembly is installed on the mounting plate for driving the screw rod to rotate to adjust the installation height of the corrosion monitor.

[0018] 2. The diameter of the upper opening of the fixed space formed by the installation frame and the fixing plate is smaller than the diameter of the lower opening, which is consistent with the appearance characteristics of the offshore wind power single pile being larger at the bottom and smaller at the top, so that the installation frame and the fixing plate are respectively in contact with the surface of the offshore wind power single pile during installation. Compared with the U-shaped fixing frame in the prior art (whose upper and lower surface openings are the same size), it is in line contact when installed outside the offshore wind power single pile that is larger at the bottom and smaller at the top, thereby increasing the contact area with the offshore wind power single pile, and the range of the clamping force on the offshore wind power single pile is larger, which is conducive to the stable installation of the offshore wind power corrosion monitoring device outside the offshore wind power single pile.

DETAILED DESCRIPTION

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0028] In the above description of the utility model, it should be noted that the terms "one side", "the other side", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0029] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0030] See also Figures 1 to 4 The utility model provides a technical solution: an offshore wind power corrosion monitoring device, comprising a mounting frame 1, wherein one end of the mounting frame 1 is provided with an arc-shaped fixed groove 2 whose diameter is smaller than the width of the mounting frame 1, two end faces are formed between the two ends of the fixed groove 2 and the mounting frame 1, and movable components 4 and fixed components 5 are respectively installed on the two end faces, and a fixed plate 3 is installed above the mounting frame 1, wherein one end of the fixed plate 3 can rotate relative to the mounting frame 1 in the horizontal and vertical directions through the movable component 4, and the other end of the fixed plate 3 can be fixedly connected to the mounting frame 1 through the fixing component 5, and the side of the fixed plate 3 close to the fixed groove 2 is an arc surface 6, and the fixed space enclosed by the arc surface 6 and the fixed groove 2 is consistent with the outer shape of the offshore wind power single pile which is large at the bottom and small at the top.

[0031] In the present solution, the arc surface of the fixing groove 2 is inclined, and the arc surface 6 is also inclined, so that the diameter of the upper opening of the fixing space formed by the installation frame 1 and the fixing plate 3 is smaller than the diameter of the lower opening, which is consistent with the appearance characteristics of the offshore wind power single pile being larger at the bottom and smaller at the top. At the same time, a rubber pad or a spring telescopic rod plus a rubber pad structure can be provided on the inner side surfaces of the fixing groove 2 and the fixing plate 3. When the fixing plate 3 and the installation frame 1 are enclosed, the friction with the offshore wind power single pile can be increased through the deformation of the rubber pad or the extension of the spring telescopic rod, and a greater radial clamping force can be provided, thereby making the installation of the offshore wind power corrosion monitoring device more stable.

[0032] When installing the offshore wind power corrosion monitoring device of the utility model, the installation frame 1 is firstly mounted on the outer side of the offshore wind power monopile, and then the free end of the fixing plate 3 is pulled to move, and the connecting end of the fixing plate 3 and the installation frame 1 is relatively rotated in the horizontal direction and the vertical direction through the movable component 4, so that the free end of the fixing plate 3 is close to and inserted into the installation frame 1, and finally the free end of the fixing plate 3 is fixed to the installation frame 1 through the fixing component 5, so that the installation frame 1 and the fixing plate 3 are clamped and installed on the outer side of the offshore wind power monopile, so as to realize the installation of the offshore wind power corrosion monitoring device. The installation frame 1 and the fixing plate 3 of the utility model are integrated with each other. Compared with the split type in the prior art, its connection and fixing operation is more convenient. Secondly, the diameter of the upper opening of the fixed space formed by the installation frame 1 and the fixing plate 3 is smaller than the diameter of the lower opening, which is consistent with the appearance characteristics of the offshore wind power monopile being larger at the bottom and smaller at the top, so that the installation frame 1 and the fixing plate 3 are respectively in contact with the surface of the offshore wind power monopile during installation. Compared with the U-shaped fixing frame in the prior art (the openings on the upper and lower surfaces are the same size), it is in line contact when installed outside the offshore wind power monopile that is larger at the bottom and smaller at the top, thereby increasing the contact area with the offshore wind power monopile, and the range of the clamping force on the offshore wind power monopile is larger, which is conducive to the stable installation of the offshore wind power corrosion monitoring device outside the offshore wind power monopile.

[0033] See also Figure 1 and Figure 3 In this embodiment, the movable component 4 includes a first rotating shaft 41 inserted into the end of the mounting frame 1, the other end of the first rotating shaft 41 is fixedly connected to a movable block 42, a second rotating shaft 43 is inserted at the top of the movable block 42, and the other end of the second rotating shaft 43 is fixedly connected to the fixed plate 3.

[0034] Specifically, the movable block 42 can rotate relative to the installation frame 1 in the vertical direction through the first rotating shaft 41, and the fixed plate 3 can rotate relative to the movable block 42 in the horizontal direction through the second rotating shaft 43, so that when the free end of the fixed plate 3 is pulled to move, the fixed plate 3 can be rotated so that the free end of the fixed plate 3 is close to and inserted into the installation frame 1 for fixation, thereby realizing the installation frame 1 and the fixed plate 3 being set as an integrated unit. Compared with the split type in the prior art, the connection and fixing operation is more convenient.

[0035] See also Figure 2 and Figure 4In this embodiment, the fixing assembly 5 includes a fixing block 51 fixedly connected to the mounting frame 1, a fixing hole 52 is opened on the top of the fixing block 51, a fixing rod 53 is inserted into the fixing hole 52, the upper end of the fixing rod 53 is fixedly connected to the fixing plate 3, and a limiting mechanism 54 is provided on the fixing block 51 for vertically limiting the fixing rod 53.

[0036] Specifically, when the free end of the fixing plate 3 is close to the installation frame 1, the fixing rod 53 is inserted into the fixing hole 52, and the fixing rod 53 is vertically limited by the limiting mechanism 54, so that the fixing rod 53 is stably inserted and connected in the fixing hole 52, thereby realizing the connection and fixation of the fixing plate 3 and the installation frame 1.

[0037] See also Figure 4 In this embodiment, a limiting hole 541 is formed at one end of the fixing block 51 away from the installation frame 1, and the limiting hole 541 is connected to the fixing hole 52 and extends toward the installation frame 1; a through hole 542 is formed on the side of the fixing rod 53, and the through hole 542 penetrates the fixing rod 53; the limiting mechanism 54 includes a limiting rod 543 penetrating the limiting hole 541 and the through hole 542, and the limiting rod 543 passes through the through hole 542 and extends out of the fixing One end of the rod 53 is fixedly connected with a bevel block 544; the limiting mechanism 54 also includes a spring 547 installed between the fixing rod 53 and the bottom wall of the fixing hole 52; the height of the bevel block 544 is greater than the diameter of the limiting rod 543, so that the connecting end of the bevel block 544 and the limiting rod 543 is stepped, and under the force generated by the deformation of the spring 547, the edge of the bottom wall of the through hole 542 abuts against the connecting end of the bevel block 544 and the limiting rod 543.

[0038] Specifically, when the fixing rod 53 is inserted into the fixing hole 52, the spring 547 is squeezed. At this time, the limiting hole 541 and the through hole 542 partially overlap. Then, the limiting rod 543 is inserted into the limiting hole 541, and the inclined block 544 is pushed to pass through and extend out of the through hole 542. Since the end of the inclined block 544 has an inclined surface, when the inclined block 544 moves close to the through hole 542, the fixing rod 53 is squeezed and pushed to move downward. After the inclined block 544 passes through the through hole 542, the spring 547 is deformed and produced. An upward thrust is generated, so that the edge of the bottom wall of the through hole 542 abuts against the connecting end of the inclined block 544 and the limiting rod 543, thereby vertically limiting the fixing rod 53, so that the fixing rod 53 is stably connected to the fixing hole 52, and the edge of the bottom wall of the through hole 542 abuts against the connecting end of the inclined block 544 and the limiting rod 543 to limit the axial direction of the limiting rod 543, which can prevent the limiting rod 543 from loosening and falling out due to vibration, thereby ensuring that the offshore wind power corrosion monitoring device is firmly installed on the offshore wind power single pile.

[0039] See also Figure 4 In this embodiment, the limiting mechanism 54 also includes an outer tube 545 fixedly connected to the end of the movable block 42 away from the mounting frame 1, and a knob 546 is threadedly connected in the outer tube 545, and the end of the knob 546 is rotatably connected to the end of the limiting rod 543 away from the inclined block 544.

[0040] Specifically, when the inclined block 544 extends into the limiting block, the knob 546 is rotated to cooperate with the thread on the outer tube 545 to move, so that the inclined block 544 can be driven to push the fixing rod 53 to move downward. At this time, the inclined block 544 passes through the through hole 542 to limit the fixing rod 53. Since the width of the limiting hole 541, the through hole 542 and the inclined block 544 is greater than the height, when the inclined block 544 extends into the limiting hole 541 and the knob 546 is rotated, the connecting end of the limiting rod 543 and the knob 546 rotates relative to each other, and does not drive the inclined block 544 to rotate, thereby ensuring that the inclined surface of the inclined block 544 is always downward. The cooperation between the knob 546 and the outer tube 545 is conducive to pushing the inclined block 544 to move, and can further limit the axial direction of the limiting rod 543 to prevent the limiting rod 543 from loosening and falling out.

[0041] See also Figure 1 and Figure 2In this embodiment, the end of the mounting frame 1 away from the fixing groove 2 is fixedly connected to a mounting plate 7, a screw rod 8 is vertically arranged on the mounting plate 7, a sleeve 9 is installed at the lower end of the screw rod 8, a corrosion monitor 10 is fixedly connected to the outer circumferential surface of the sleeve 9, and a driving assembly 11 is installed on the mounting plate 7 for driving the screw rod 8 to rotate and adjust the installation height of the corrosion monitor 10; the driving assembly 11 includes a driving motor 111 fixedly connected to the top of the mounting plate 7, the model of the driving motor is ECMA-E21315RS, and the output end of the driving motor 111 is fixedly connected to a first gear 112, and the upper end of the screw rod 8 is fixedly connected to a second gear 113, and the second gear 113 is meshed with the first gear 112.

[0042] Specifically, the upper end of the screw rod 8 is connected to the mounting plate 7 through a bearing. When the output end of the driving motor 111 drives the first gear 112 to rotate, the first gear 112 is engaged with the second gear 113, thereby driving the screw rod 8 to rotate. The rotation of the screw rod 8 can drive the sleeve 9 to move up and down along the screw rod 8, and then the height of the corrosion monitor 10 can be adjusted to ensure that the monitoring end of the corrosion monitor 10 is below sea level to obtain the corrosion condition of the offshore wind power single pile. The model of the corrosion monitor 10 is GS-FSY-2, and its specific structure and working principle are prior art, which will not be described in detail here.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
