Description

Technical Field

[0001] This utility model relates to the field of marine machinery technology, and in particular to a centering device for ship cables. Background Technology

[0002] Modern ships generally use electrically or hydraulically driven winch systems to retrieve and deploy cables, and guide wheels or pulley blocks are installed in the cable path to guide the cable into the center position of the retrieval device through mechanical constraints.

[0003] However, after repeated immersion in seawater, salt particles easily adhere to the surface of the cable, which not only increases the friction between the cable and the guide wheel and accelerates the wear of the guide wheel, but also causes salt crystallization to exacerbate the corrosion of the cable and shorten its service life.

[0004] To address this problem, we propose a centering device for ship cables. Utility Model Content

[0005] The purpose of this invention is to provide a centering device for ship cables to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A centering device for ship cables includes a base and a pair of guide wheels. The surface of each guide wheel is evenly provided with several spray holes, and the interior of each guide wheel is hollow, forming a through hole communicating with the spray holes. A base is installed under each guide wheel, and a hollow shaft is rotatably connected through the base. The hollow shaft is coaxially connected to the guide wheels, and a diversion pipe is connected to the hollow shaft via a rotary joint. The two diversion pipes are connected by a T-shaped pipe, and the T-shaped pipe is connected to a water tank containing a salt-dissolving cleaning solution via a piezoelectric pump and a rigid pipe.

[0008] In a further embodiment, the guide wheel is thicker at both ends and thinner in the middle, and the cross-sectional structure of the guide wheel is V-shaped.

[0009] In a further embodiment, the surface of the guide wheel is provided with several annular grooves, and the spray holes are evenly distributed along the circumference of the annular grooves.

[0010] In a further embodiment, an activated carbon filter screen is installed at the interface between the rigid pipe and the water tank.

[0011] In a further embodiment, a pair of parallel double-ended screws and a smooth rod are installed inside the base, and the two ends of the double-ended screws are rotatably connected to the base. The two bases are symmetrically threaded onto the two threaded sections of the double-ended screws, and the thread directions of the two threaded sections of the double-ended screws are opposite. The smooth rod is slidably connected to the base, and a motor that drives the double-ended screws to rotate is installed outside the base.

[0012] In a further embodiment, the diverter is a telescopic corrugated pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention connects a guide wheel to a water tank, allowing the guide wheel to not only guide and limit the cable, but also spray cleaning fluid onto the cable surface while rotating. This dissolves salt crystals on the cable surface, effectively slowing down the corrosion of the cable by salt crystals and reducing wear on the guide wheel. Attached Figure Description

[0020] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 A centering device for ship cables includes a base 1 and a pair of guide wheels 2. The surface of each guide wheel 2 is evenly provided with several nozzles 21, and the interior of each guide wheel 2 is hollow, forming an axial through-hole 23 communicating with the nozzles 21. A base 3 is mounted below each guide wheel 2, and a hollow shaft 4 passes through and is rotatably connected to the base 3. The hollow shaft 4 is coaxially connected to the guide wheels 2 and communicates with the through-hole 23. A shunt pipe 6 is connected to the lower part of the hollow shaft 4 via a rotary joint 5. The two shunt pipes 6 are connected by a T-tube 7, and the tail end of the T-tube 7 is connected to the output end of a piezoelectric pump 8. The input end of the piezoelectric pump 8 is connected via a rigid... Pipe 9 is connected to water tank 10. Specifically, water tank 10 is installed under base 1. The connection point between rigid pipe 9 and water tank 10 is located at the lower edge of side of water tank 10. Water tank 10 is also provided with a screw-on cap on the upper surface to cover the liquid filling port. Water tank 10 stores a salt-dissolving cleaning solution. Specifically, the cleaning solution is fresh water mixed with 5% corrosion inhibitor. When the cable passes between a pair of guide wheels 2, it drives the pair of guide wheels 2 to rotate, starting piezoelectric pump 8. Piezoelectric pump 8 delivers the cleaning solution in water tank 10 to guide wheels 2, and finally sprays it out from nozzle 21 onto the surface of the cable to dissolve salt crystals on the surface of the cable.

[0024] Furthermore, the guide wheel 2 is thicker at both ends and thinner in the middle, and the cross-sectional structure of the guide wheel 2 is V-shaped, which increases the contact area between the guide wheel 2 and the cable, thereby better limiting the cable in multiple directions. The surface of the guide wheel 2 is provided with several annular grooves 22, and the nozzles 21 are evenly distributed around the annular grooves 22, so that when the cable contacts the surface of the guide wheel 2, it will not block the nozzles 21, ensuring the unobstructed flow of the nozzles 21.

[0025] An activated carbon filter 11 is installed at the interface between the rigid pipe 9 and the water tank 10 to prevent impurities from entering the pipe.

[0026] Considering that the surface diameter of the cable changes due to wear and tear over long-term use, a pair of parallel double-ended screws 12 and smooth rods 14 are installed inside the base 1 to better limit the cable's movement. The two ends of the double-ended screws 12 are rotatably connected to the two side plates of the base 1, while the smooth rods 14 are fixedly connected to the two side plates of the base 1. The two bases 3 are symmetrically threaded onto the two threaded sections of the double-ended screws 12, and the thread directions of the two threaded sections of the double-ended screws 12 are opposite. The smooth rods 14 are slidably connected to the bases 3, so that when the double-ended screws 12 rotate, under the limiting action of the smooth rods 14, the two bases 3 drive the two guide wheels 2 to move closer or further apart, adjusting the distance so that the guide wheels 2 can always press tightly around the cable. A motor 13 is installed on the outside of one side plate of the base 1, and the output shaft of the motor 13 is connected to the double-ended screws 12 to drive the double-ended screws 12 to rotate.

[0027] Furthermore, since the distance between the two guide wheels 2 is adjustable, in order to ensure the stability of the cleaning fluid delivery pipeline, the diversion pipe 6 is made of a telescopic corrugated pipe, thereby adaptably adjusting the length.

[0028] In addition, the outer surfaces of all components of this device need to be coated with an epoxy resin layer. Since silicone is resistant to salt spray corrosion, it is more suitable for marine environments.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
