[0066] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples of methods and devices consistent with some aspects of the utility model as detailed in the attached claims.

[0067] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can, for example, be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0068] As mentioned in the background technology part, the anchor and anchor chain are heavy. During the anchoring process, the anchor chain is quickly dropped so that the anchor is quickly anchored in the ideal position. Usually, high temperature is often generated between the guide wheel and the anchor chain due to friction, which is generally cooled naturally. In the related technology, there is a device for water cooling the anchor chain, however, it does not take into account the cooling of the guide wheel, which affects the service life of the guide wheel and the reliability of the mooring.

[0069] In view of the above problems existing in the prior art, an embodiment of the utility model provides a guide device and an offshore wind power operation and maintenance system. The guide device provided by the embodiment of the utility model includes a support mechanism, a guide wheel and a cooling mechanism. The support mechanism is connected to the hull, and the guide wheel is rotatably connected to the support mechanism. A wheel groove matching the anchor chain is provided on the circumference of the guide wheel, and the anchor chain is guided by the wheel groove. Among them, the cooling mechanism includes at least one shell and a conveying assembly. The shell is connected to the support mechanism, and the shell abuts against at least part of the side wall of the guide wheel, and a condensation chamber is enclosed to form. The conveying assembly is connected to the condensation chamber to convey coolant into the condensation chamber. That is, by conveying coolant into the condensation chamber between the shell and the guide wheel to cool the guide wheel, the high temperature between the anchor chain and the guide wheel can be suppressed, thereby ensuring the service life of the guide wheel and the reliability of mooring.

[0070] The following specific embodiments are combined with the accompanying drawings to describe the technical solutions of the embodiments of the utility model in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0071] First, please refer to Figures 1 to 5 As shown, the guide device provided in this embodiment is used to guide the anchor chain 20 on the hull 10, and the guide device includes a support mechanism 100, a guide wheel 200 and a cooling mechanism 300, and the support mechanism 100 is used to be connected to the hull 10. The guide wheel 200 is rotatably connected to the support mechanism 100, and a wheel groove 210 for matching with the anchor chain 20 is provided on the circumference of the guide wheel 200.

[0072] The cooling mechanism 300 includes at least one shell 310 and a conveying assembly 320. The shell 310 is connected to the supporting mechanism 100. The shell 310 abuts against at least part of the side wall of the guide wheel 200 to enclose and form a condensation chamber 201. The conveying assembly 320 is in communication with the condensation chamber 201 to convey the cooling liquid into the condensation chamber 201.

[0073] In this embodiment, the hull 10 can be the hull of an offshore wind power operation and maintenance vessel. For example, a windlass, an anchor chain 20 and an anchor can be set at the bow position of the hull 10. The anchor is connected to the windlass through the anchor chain 20. The part of the anchor chain 20 on the hull 10 is roughly in a horizontal transverse state, and the part of the anchor chain 20 entering the water is roughly in a vertical or inclined state. In order to allow the anchor chain 20 to smoothly transition between the two states, the guide device can be installed on the hull 10, and the part of the anchor chain 20 between the windlass and the anchor can be supported and guided to avoid direct contact between the anchor chain 20 and the hull 10.

[0074] The support mechanism 100 is used to provide a basis for part of the anchor chain, the guide wheel 200 and the cooling mechanism 300. It can be a frame-shaped, shell-shaped or other structure. The support mechanism 100 can be fastened to the hull 10 by means of screwing, welding, riveting or the like.

[0075] The guide wheel 200 can be installed on the support mechanism 100 through a rotating structure such as a rotating shaft and a bearing. The rotating axis is arranged roughly in the horizontal direction. A wheel groove 210 is provided on the circumference of the guide wheel 200 so that the anchor chain 20 can be placed in the wheel groove 210 for limiting, thereby preventing the anchor chain 20 from falling off the guide wheel 200. The size of the guide wheel 200 can be determined according to actual needs.

[0076] The shell 310 is used to contact the side wall of the guide wheel 200 and enclose a cooling cavity. One is that a concave cavity can be opened on the shell 310 or the side wall of the guide wheel 200 to form a cooling cavity, and the other is that concave cavities can be opened on both sides to form a cooling cavity. The side wall here refers to the end surface of the guide wheel 200 located on both sides of the wheel groove 210. The shell 310 is connected to at least one of the side walls to perform liquid cooling on the end surface.

[0077] In one example, one side of the shell 310 can be fixedly connected to the support mechanism 100, and the other side of the shell 310 can abut against the side wall and rotate relatively, so that the shell 310 and the side wall can enclose a condensation chamber 201. In another example, one side of the shell 310 can abut against the support mechanism 100, and the other side of the shell 310 can be fixedly connected to the side wall, so that the shell 310 and the side wall can also enclose a condensation chamber 201.

[0078] The delivery assembly 320 is used to deliver coolant to the condensation chamber 201, and it can be composed of a pump and a pipeline. For the two connection methods between the shell 310 and the side wall, on the one hand, the inlet and outlet can be opened on the fixed shell 310, and on the other hand, a pipeline can be opened in the support mechanism 100 so that the pipeline is connected to the condensation chamber 201 along the axis direction of the guide wheel 200. The coolant mentioned here can be a liquid medium such as water and oil.

[0079] Specifically, the support mechanism 100 can be fixed on the bow or hull side of the offshore wind power operation and maintenance vessel. When part of the anchor chain 20 abuts against the wheel groove 210 and drives the guide wheel 200 to rotate, the conveying component 320 conveys coolant to the condensation chamber 201 to cool the guide wheel 200.

[0080] It can be understood that, compared with the method of air cooling or no cooling between the anchor chain 20 and the guide wheel 200, the guide device provided in this embodiment cools the guide wheel 200 by conveying coolant to the condensation chamber 201 between the shell 310 and the guide wheel 200, which can suppress the high temperature between the anchor chain 20 and the guide wheel 200, thereby ensuring the service life of the guide wheel 200 and the reliability of the mooring of the operation and maintenance ship.

[0081] Therefore, the guiding device provided by the embodiment of the utility model includes a supporting mechanism 100, a guiding wheel 200 and a cooling mechanism 300. The supporting mechanism 100 is connected to the hull 10, and the guiding wheel 200 is rotatably connected to the supporting mechanism 100. The circumference of the guiding wheel 200 is provided with a wheel groove 210 matching the anchor chain 20, and the anchor chain 20 is guided by the wheel groove 210. The cooling mechanism 300 includes at least one shell 310 and a conveying assembly 320, which is connected to the supporting mechanism 100 through the shell 310. The shell 310 abuts against at least part of the side wall of the guiding wheel 200, and encloses to form a condensation chamber 201, and the conveying assembly 320 is connected to the condensation chamber 201 to convey the cooling liquid into the condensation chamber 201. That is, by delivering coolant to the condensation chamber 201 between the shell 310 and the guide wheel 200, the guide wheel 200 is cooled, which can suppress the high temperature between the anchor chain 20 and the guide wheel 200, thereby ensuring the service life of the guide wheel 200 and the reliability of the mooring of the maintenance ship.

[0082] In a possible design, there are two shells 310 , which are arranged oppositely on two sides of the guide wheel 200 . The guide wheel 200 has a flow channel 220 connecting the two condensation chambers 201 .

[0083] Specifically, Figure 1 , Figure 2 , Figure 4 As shown, a shell 310 is provided on both end faces of the guide wheel 200, so that both end faces of the guide wheel 200 have a condensation chamber 201, and a flow channel 220 is opened on the guide wheel 200 in a direction parallel to the rotation axis, so that the two end faces of the guide wheel 200 and the interior of the guide wheel 200 are easier to cool, thereby enhancing the cooling effect.

[0084] The larger the area of ​​the flow channel 220, the stronger the ability of the coolant to circulate, and the more obvious the cooling effect, but the flow channels 220 should not be too many or too large, so as not to affect the support strength of the guide wheel 200. Therefore, the specific shape, number, position, etc. of the flow channel 220 can be determined according to actual needs and are not specifically limited in this embodiment.

[0085] Furthermore, in this embodiment, a guide portion 230 is provided in the flow channel 220 , and the guide portion 230 is configured to guide the coolant in one condensation chamber 201 to another condensation chamber 201 .

[0086] For example, Figure 4As shown, the guide portion 230 is fan-shaped or paddle-shaped. In this way, when the guide wheel 200 rotates, the coolant in one condensation chamber 201 is guided to another condensation chamber 201, which can accelerate the flow of the coolant and improve the cooling effect of various parts on the guide wheel 200. When the guide wheel 200 rotates in the opposite direction, the coolant is guided from one condensation chamber 201 to another condensation chamber 201 in the opposite direction, which can also accelerate the flow of the coolant.

[0087] It should be noted that the guide portion 230 here is equivalent to stirring the coolant so that the coolant in the two condensation chambers 201 flows to each other, and does not only refer to a unidirectional flow from one condensation chamber 201 to another condensation chamber 201 .

[0088] Furthermore, in this embodiment, the two shells 310 are respectively provided with a liquid inlet 311 and a liquid return port 312 connected to the condensing chamber 201, and the delivery assembly 320 includes a delivery pipeline 321, a delivery pump 322 and a liquid storage tank 323. The liquid inlet 311 and the liquid return port 312 are respectively connected to the delivery pump 322 and the liquid storage tank 323 through the delivery pipeline 321, and form a coolant circulation loop.

[0089] Specifically, Figure 1 , Figure 2 As shown, a liquid inlet 311 is provided on one housing 310, and a liquid return port 312 is provided on the other housing 310. The inlet of the delivery pump 322 is connected to the liquid storage tank 323, the outlet of the delivery pump 322 is connected to the liquid inlet 311 through the delivery pipeline 321, and the liquid return port 312 is connected to the liquid storage tank 323 through the delivery pipeline 321.

[0090] In this way, after the coolant in the condensing chamber 201 is heated, it can return to the liquid storage tank 323 to dissipate heat. The cooled coolant can cool the condensing chamber 201, thereby ensuring the cooling effect. The specific models of the delivery pipeline 321, the delivery pump 322, and the liquid storage tank 323 can be determined according to actual needs. Of course, the delivery component 320 can also be replaced by other components capable of delivering coolant, which is not specifically limited in this embodiment.

[0091] In some embodiments, the housing 310 has a first flange 313 on one side facing the guide wheel 200, and the guide wheel 200 is provided with a second flange 240 matching the first flange 313. The second flange 240 is rotatably connected to the first flange 313, and the rotation axis coincides with the axis of the guide wheel 200, and a first sealing member 202 is further provided between the second flange 240 and the first flange 313.

[0092] In one example, Figure 2 , Figure 3As shown, the inner diameter of the first flange 313 is larger than the outer diameter of the second flange 240, and the second flange 240 is embedded in the first flange 313 to form a rotational fit. In another example, not shown in the figure, the outer diameter of the first flange 313 is smaller than the inner diameter of the second flange 240, and the first flange 313 is embedded in the second flange 240 to form a rotational fit. As for which rotational connection method is adopted, it can be determined according to actual needs and is not specifically limited in this embodiment.

[0093] In order to ensure the sealing between the first flange 313 and the second flange 240, the first sealing member 202 may be an annular sealing ring, which fills the gap between the first flange 313 and the second flange 240. In addition, a groove for limiting the annular sealing ring may be provided on the first flange 313 or the second flange 240 to prevent the annular sealing ring from falling off. The specific type and size of the first sealing member 202 may be determined according to actual needs and are not specifically limited in this embodiment.

[0094] Furthermore, in this embodiment, the support mechanism 100 includes a base 110 and a first bracket 120 connected to the base 110, and the base 110 is used to be connected to the hull 10. One of the first bracket 120 and the guide wheel 200 is provided with an axis hole 121, and the other is provided with an axis head 250 matching the axis hole 121, and the axis head 250 is rotatably connected to the axis hole 121.

[0095] Specifically, Figure 1 , Figure 2 As shown, the base 110 is used to support the first bracket 120, and it can be a columnar, block-shaped structure, etc. The base 110 can be connected to the hull 10 by screwing, welding, etc.

[0096] The first bracket 120 is used to support the guide wheel 200 and provide a mounting base. For example, the first bracket 120 may include two columns and a connecting rod, and the connecting rod connects and fixes the two parallel columns. Figure 3 As shown, the column is provided with an axial hole 121, and the side wall of the guide wheel 200 is coaxially provided with an axial head 250, which is rotatably connected in the axial hole 121 to rotatably support the guide wheel 200. In order to ensure the stability of the support for the guide wheel 200, the axial holes 121 are relatively arranged on the two columns, and the two end surfaces of the guide wheel 200 are relatively arranged with axial heads 250, which are rotatably connected with the two axial holes 121 through the two axial heads 250.

[0097] In another example, which is not shown in the figure, a shaft head 250 may also be provided on the column, and a shaft hole 121 is coaxially provided on the side wall of the guide wheel 200, and the shaft head 250 is rotatably connected in the shaft hole 121 to rotatably support the guide wheel 200. As for which rotatable connection method is adopted, it can be determined according to actual needs and is not specifically limited in this embodiment.

[0098] Furthermore, in this embodiment, the shaft head 250 is connected to the shaft hole 121 through the bearing 203 and the second sealing member 204 , and the second sealing member 204 is located between the bearing 203 and the condensation chamber 201 .

[0099] For example, Figure 4 As shown, the bearing 203 can be a sliding bearing, a rolling bearing, etc., and the shaft head 250 is connected to the shaft hole 121 through the bearing 203, which can reduce friction resistance. At the same time, a second seal 204 is arranged between the shaft head 250 and the shaft hole 121. The second seal 204 can be a skeleton seal ring, etc. The second seal 204 is located between the bearing 203 and the condensation chamber 201 to prevent the coolant in the condensation chamber 201 from affecting the bearing 203 and ensure the service life. The specific type and size of the bearing 203 and the second seal 204 can be determined according to actual needs, and are not specifically limited in this embodiment.

[0100] In addition, an oil filling hole connected to the shaft hole 121 can also be provided to fill the bearing 203 with lubricating oil.

[0101] Optionally, in this embodiment, one of the base 110 and the first bracket 120 is provided with a first plug-in portion 111, and the other is provided with a second plug-in portion 122 matching the first plug-in portion. The second plug-in portion 122 is plugged with the first plug-in portion 111 and moves relatively. An elastic member 101 is provided between the second plug-in portion 122 and the first plug-in portion 111 for buffering.

[0102] For example, the lower ends of the two columns are provided with a second plug-in portion 122, the second plug-in portion 122 is a plug, and the base 110 is provided with a first plug-in portion 111 side by side, the first plug-in portion 111 is a socket matching the plug, the plug is plugged into the socket, and moves relatively up and down. The elastic member 101 can be a buffer spring, an elastic pad, etc., and the elastic member 101 can be sleeved in the first plug-in portion 111 and the second plug-in portion 122, and the two ends of the elastic member 101 are respectively in contact with the first plug-in portion 111 and the second plug-in portion 122.

[0103] In this way, when the sea waves drive the hull 10 to move up and down, the waves are transmitted to the base 110 through the anchor chain 20, the guide wheel 200, and the first bracket 120, and the elastic member 101 can play a buffering role.

[0104] Of course, the first plug-in portion 111 may also be a plug, and correspondingly, the second plug-in portion 122 may be a socket matching the plug, which can also achieve plug-in. Moreover, the elastic member 101 may also be replaced by other elastic members, which is not specifically limited in this embodiment.

[0105] Further, in this embodiment, the support mechanism 100 further includes a second bracket 130, and the second bracket 130 is used to be connected to the hull 10. A first sliding portion 131 is provided on one of the second bracket 130 and the first bracket 120, and a second sliding portion 123 matching the first sliding portion 131 is provided on the other. The second sliding portion 123 is slidably connected to the first sliding portion 131, and at least part of the slidably connected section is close to the shaft head 250 or the shaft hole 121.

[0106] Specifically, Figure 1 , Figure 2 As shown, the second bracket 130 is used to support and guide the first bracket 120 to increase the support strength of the first bracket 120. The second bracket 130 can be a frame, shell or other structure, which can be connected to the hull 10 by screwing, welding or other methods.

[0107] For example, continue as Figure 1 , Figure 2 As shown, the two columns are provided with a second sliding part 123, which can be a sliding column. Correspondingly, the second bracket 130 is relatively provided with a first sliding part 131, which can be a sliding sleeve matching the sliding column. The sliding column is slidably connected with the sliding sleeve, and at least part of the sliding connection section is close to the shaft head 250 or the shaft hole 121 to strengthen the support strength of the guide wheel 200 and prevent it from tipping over. The sliding direction of the sliding column and the sliding sleeve is consistent with the moving direction of the first plug-in part 111 and the second plug-in part 122.
