Description

Technical Field

[0001] This utility model relates to the field of armored cable maintenance technology, specifically to a device for rinsing, drying and oiling armored cables. Background Technology

[0002] During marine scientific research and exploration operations, armored cables are frequently used for towing, deploying and retrieving underwater equipment, as well as for power supply and communication transmission. These armored cables are constantly exposed to the high-salt, high-humidity marine environment, making their surfaces highly susceptible to the accumulation of salt and impurities. More seriously, under seawater pressure, seawater can seep into the gaps and joints of the steel wires inside the armored cable. Failure to clean and maintain the cables thoroughly and promptly will accelerate corrosion, significantly shortening their lifespan and potentially leading to serious safety accidents.

[0003] Currently, on-site operations typically rely on oiling devices for the maintenance of armored cables, such as the CN216459745U_ROV armored cable cleaning and oiling device. However, existing equipment has significant limitations: (1) Incomplete cleaning: it can only remove surface dirt and cannot effectively drain seawater that has seeped into the gaps in the steel wires; (2) Insufficient lubrication: it cannot fully squeeze the lubricating grease into the internal gaps, resulting in uneven oiling. These problems mean that the risk of internal corrosion of armored cables persists for a long time, and there is an urgent need to develop more efficient deep cleaning devices. Utility Model Content

[0012] Furthermore, the brush is a spiral brush.

[0013] Furthermore, the second housing consists of two semi-circular housings, which are fixed and locked together by a plurality of horn bolts.

[0014] Furthermore, the drying structure includes a first housing, the first housing having a first channel along the axial direction, the first channel being for the armored cable to pass through;

[0023] This utility model relates to a device for rinsing, drying, and oiling armored cables. It can perform high-pressure deep cleaning and uniform oiling protection on armored cables during the cable recycling process. It is easy to operate and can automatically and synchronously complete cleaning, maintenance, and recycling, resulting in high work efficiency.

[0038] This embodiment describes a device for rinsing, drying and oiling armored cables, which simultaneously completes an integrated maintenance process of deep rinsing, drying and oiling of armored cables during the cable retrieval process using a matching winch.

[0039] like Figures 1 to 5As shown, the device includes a rinsing structure, a drying structure, an oiling structure, a support platform 15, an air compressor 20, a lubricating grease pump 21, and a high-pressure water pump 22. The rinsing and drying structures work together to clean the armored cable 1, and the cleaned armored cable 1 is then oiled by the oiling structure for maintenance. For ease of operation, the rinsing, drying, and oiling structures are respectively mounted on the support platform 15. The air compressor 20, lubricating grease pump 21, and high-pressure water pump 22 are integrated into one unit, providing high-pressure gas, lubricating oil, and high-pressure water to the drying, oiling, and rinsing structures, respectively.

[0040] The flushing structure is used to flush the surface of the armored cable 1 during cable winding, and includes a water spray head 3, a first support frame 4, and an annular pipe structure 5. Multiple annular pipe structures 5 are arranged in parallel at intervals and connected as a whole by two vertically arranged manifolds, with the manifolds communicating with the interior of the annular pipe structures 5. Several water spray heads 3 are arranged around the inner side of the annular pipe structures 5; in this embodiment, the water spray heads 3 are high-pressure spray heads. The upper and lower manifolds of the flushing structure are provided with water inlets 2, which are connected to the water injection port 18 of the high-pressure water pump 22 via flexible hoses.

[0041] The armored cable 1 passes through the inside of the annular pipe structure 5. Fresh water is pressurized by the high-pressure water pump 22 to form high-pressure water. The high-pressure water flows into the annular pipe structure 5 through the inlet 2 via the hose. The annular pipe structure 5 sprays water from different directions through the spray nozzles 3 at different angles to rinse the armored cable 1 360° without dead angles, washing away salt stains, impurities and seawater that has seeped into the gaps in the steel wires.

[0042] The flushing structure is mounted on the support platform 15 via the first support frame 4. The first support frame 4 is an adjustable structure, which can adopt an existing height adjustment structure. For example, in this embodiment, the first support frame 4 consists of two gantry frames. The gantry frames have two lifting columns, and the lifting columns are composed of an upper column and a lower column. The lower column is a hollow structure, and multiple pin holes are arranged in an axial array on the upper column. The upper column is inserted into the lower column, and the upper column and the lower column are fixed by screws inserted into the pin holes. The support height of the first support frame 4 can be controlled by the cooperation of the screws with the pin holes of different heights.

[0043] A water collection trough can be installed on the support platform 15 below the flushing structure so that the wastewater after flushing can be collected and flowed out in a directional manner.

[0044] The drying structure is used to dry the armored cable 1 after rinsing. It includes a second support frame 7, a first clamp 9, and a first housing 10. The first housing 10 is installed on the top of the second support frame 7 through the first clamp 9. The second support frame 7 is installed on the support platform 15.

[0045] The first housing 10 is a hollow cylindrical housing composed of two detachable semi-circular housings, and is secured by multiple bolts 6. The first housing 10 has a first channel along the axial direction for the armored cable 1 to pass through.

[0046] At least two air compression ports 8 are symmetrically arranged on the first housing 10. The air compression ports 8 are connected to the output port of the air compressor 20 via hoses, and the air compressor 20 provides power for compressed air. After being pressurized by the air compressor 20, the air is blown into the first housing 10 from different directions through the two air compression ports 8, and blown towards the armored cable 1 passing through the first channel to dry the armored cable 1. Air outlets are provided on the left and right sides of the first housing 10. The air outlets can be separate outlets or openings at the ends of the first channel, and the diameter of the first channel is larger than the diameter of the armored cable 1, so that air can be blown out from the gap between the two. Alternatively, the first housing 10 can be a cylindrical structure with openings at both ends.

[0047] The second support frame 7 in this embodiment is a flexible telescopic support frame, which can adopt the same structure as the first support frame 4 in order to adjust the support height so that the first housing 10 is coaxial with the annular tube structure 5, ensuring that the armored cable 1 can move horizontally.

[0048] The oiling structure is used to apply oil to the surface of the dried armored cable 1. It includes a second clamp 11, a second housing 13 and a third support frame 14. The second housing 13 is installed on the top of the third support frame 14 through the second clamp 11. The third support frame 14 is installed on the support platform 15.

[0049] The second housing 13 consists of two detachable semi-circular housings, which are secured and locked together by multiple spur bolts 16. A second channel is provided inside the second housing 13 for the armored cable 1 to pass through. Sealing elements are provided on the mating surfaces of the two semi-circular housings and at the openings at both ends of the second channel to prevent oil leakage from the oiled structure when the armored cable 1 passes through the second channel.

[0050] An oil inlet 12 is provided on the upper part of the second housing 13. The oil inlet 12 is connected to the oil outlet 19 of the lubricating grease pump 21 via a hose. After the lubricating oil is pressurized by the lubricating grease pump 21, it is input into the second housing 13 under high pressure until the second channel is filled with lubricating oil and reaches the predetermined pressure. As the armored cable 1 moves in the second channel, it will continuously carry away the lubricating oil in the second channel. New lubricating oil is continuously replenished into the second housing 13 through the oil inlet 12, so that the predetermined pressure in the second channel is always maintained.

[0051] In this embodiment, brushes 17, coaxial with the second channel, are respectively installed on the left and right sides of the second housing 13. Figure 6 As shown, the two brushes 17 are spiral brushes, and the inner diameter of the brushes 17 is slightly smaller than the outer diameter of the armored cable 1. When the armored cable 1 passes through the second channel, the brushes 17 squeeze the armored cable 1 and apply oil to the surface of the armored cable 1, so as to achieve uniform application of lubricating oil to the surface of the armored cable 1 and ensure the uniformity of oil application.

[0052] An oil discharge port is provided at the bottom of the second housing 13 for discharging the lubricating oil inside the second housing 13. An overflow valve is provided at the top of the second housing 13 and is connected to the oil return line. When the lubricating oil in the second channel exceeds the rated pressure, the oil is returned through the overflow valve.

[0053] The third support frame 14 is a flexible telescopic support frame, which can adopt the same structure as the first support frame 4 in order to adjust the support height so that the second shell 13 is coaxial with the first shell 10 and the annular tube structure 5, ensuring that the armored cable 1 always moves in a straight line along the horizontal axis during the cleaning and oiling process.

[0054] The working process of the device for rinsing, drying and oiling armored cables in this embodiment, in conjunction with the winch for recovering armored cable 1, is as follows:

[0055] 1. A device for washing, drying and oiling armored cables is assembled near the cable outlet of the winch. The support height of the first support frame 4, the second support frame 7 and the third support frame 14 is adjusted according to the height of the armored cable 1 at the cable outlet, so that the central axis of the annular tube structure 5, the first housing 10 and the second housing 13 is consistent with the height of the armored cable 1, so as to ensure that the armored cable 1 is always in a horizontal and taut state during the winch retrieval process.

[0056] 2. After the armored cable 1 is maintained and repaired to a predetermined length, it passes through the flushing structure, drying structure, and oiling structure in sequence and is then connected to the winch; the drying structure and oiling structure clamp and lock the armored cable 1.

[0057] 3. Turn on the air compressor 20 and the lubricating grease pump 21. After the second housing 13 is filled with lubricating oil and reaches the predetermined pressure, start the high-pressure water pump 22.

[0058] 4. After fresh water is pumped out by high-pressure water pump 22, it flows into the annular pipe structure 5 under high pressure and is sprayed onto the surface of armored cable 1 through spray nozzle 3, rinsing the armored cable 1 in 360° without dead angles, washing away salt stains, impurities and seawater that has seeped into the gaps of the steel wire on the armored cable 1.

[0059] 5. The winch starts to wind up the armored cable 1 and pulls the armored cable 1 to slide; the washed armored cable 1 enters the first channel, and the air compressor 20 blows high-pressure air into the first channel through the air compression interface 8 to dry the surface of the armored cable 1.

[0060] 6. After drying, the armored cable 1 enters the second channel under tension. As it passes through the second channel, lubricating oil pressurized by the lubricating grease pump 21 adheres to the surface of the armored cable 1, while the brush 17 applies lubricating oil to the surface of the armored cable 1. After being coated with oil, the armored cable 1 is pulled out of the second channel and wound onto the winch, completing the maintenance of the armored cable 1.

[0061] 7. During the recovery of armored cable 1, lubricating grease pump 21 continuously replenishes lubricating oil into the second channel through oil injection port 12.

[0062] Although the principles of this utility model have been described in detail above with reference to preferred embodiments, those skilled in the art should understand that the above embodiments are merely illustrative explanations of the implementation of this utility model and are not intended to limit the scope of this utility model. The details in the embodiments do not constitute a limitation on the scope of this utility model. Any obvious changes, such as equivalent transformations or simple substitutions, based on the technical solution of this utility model without departing from its spirit and scope fall within the protection scope of this utility model.
