Description

Technical Field

[0001] The utility model relates to the technical field of towing cable flushing, in particular to a main towing cable high-pressure flushing device. Background Art

[0002] The main towline is one of the key equipment of the tugboat. It is generally made of galvanized high-performance steel wire strands, with high strength, high torsion, low relaxation and other characteristics. It needs good maintenance in daily use to maintain its strength and performance for a long time. After the offshore towing operation is completed and the towed object is untied, in the process of recovering the main towline, it is necessary to use high-pressure fresh water to thoroughly rinse the main towline to remove the seawater and salt on the main towline, so as to prevent rust and corrosion on the main towline.

[0003] However, the current offshore towing operation requires a dedicated person to use a high-pressure water gun to flush the towline when the main towline is being collected. The operator is close to the towline, which poses a high safety risk. In addition, the manual flushing method of the high-pressure water gun can only achieve single-sided flushing, resulting in slow flushing efficiency and easily leading to insufficient cleanliness of the main towline.

[0004] In view of the existing technology, we propose a main tow cable high-pressure flushing device to solve the shortcomings of the existing technology. Utility Model Content

The fixing clip 41 is an Ω-shaped fixing clip, which is connected to the mounting body 1 by screws or welding.

[0025] A plurality of high-pressure nozzles 31 are evenly distributed on one side of the annular cavity 3 away from the mounting body 1. Each of the high-pressure nozzles 31 is tilted toward the flushing center at a certain angle, specifically, 20°-30° toward the flushing center. Preferably, the high-pressure nozzle 31 is tilted toward the flushing center at 25°. The plurality of high-pressure nozzles 31 enclose a high-pressure flushing area outside the main streamer to achieve all-round flushing of the main streamer.

[0026] The high-pressure nozzle 31 is detachably mounted on the annular cavity 3 , and the manner of detachable mounting is well-known technology, so it will not be described in detail here.

[0027] The annular cavity 3 is connected to the connecting steel pipe 4 through a quick connector male and female. The connecting steel pipe 4 is connected to a quick connector 42 at one end away from the annular cavity 3, and is connected to an external water pipe through the quick connector 42.

[0028] The mounting body 1 is of U-shaped structure and is formed by bending a 1-2 mm thick steel plate. The upper portion of the mounting body 1 has an opening, and the four corners of the opening are respectively provided with wing panels 11 that are bent and extended inwardly. The two wing panels 11 located at the front or rear of the mounting body 1 are arranged opposite to each other.

[0029] The installation body 1 has a guide structure inside for guiding the main towline. The guide structure is provided with at least two groups, and the two groups of guide structures are respectively provided at the front and rear parts of the installation body 1. Specifically, the guide structure is composed of four guide rollers 2, and the four guide rollers 2 enclose a channel 21 for the main towline to pass through. The guide rollers 2 are detachably installed on the installation body 1. When installed, the center of the guide roller 2 passes through the screw rod 22, and the two ends of the screw rod 22 are fixedly connected to the installation body 1 through nuts 23. The two ends of the screw rod 22 have threads that match the nuts 23. Among them, the guide rollers 2 parallel to the left and right sides of the installation body 1 are arranged oppositely, and the upper ends of the screw rods 22 connected to the guide rollers 2 on the left and right sides are fixed on the wing plate 11; the guide rollers 2 parallel to the upper and lower sides of the installation body 1 are arranged in a front-to-back staggered manner, the length of the guide roller 2 located at the top is longer than the length of the guide roller 2 located at the bottom, and the upper guide roller 2 is located at the opening of the installation body 1. Of course, the guiding structure is not limited to the form described in this embodiment, and any form that can achieve the same function as the present application should be included.

[0030] The guide roller 2 is cylindrical or hyperbolic or approximately hyperbolic. The guide roller 2 is a nylon roller or a rubber roller.

[0031] Two annular cavities 3 can be provided, and the two annular cavities 3 are respectively provided at the front and rear ends of the mounting body 1. The high-pressure nozzle 31 on one of the annular cavities 3 can perform secondary flushing on the main streamer, further improving the cleanliness of the flushing of the main streamer.

[0034] The outer walls of both sides of the mounting body 1 are provided with mounting rings (not marked in the figure) for connecting with the thin rope.

[0035] When in use, first remove the screw rod 22 and the guide roller 2 at the opening of the installation body 1, clamp the device on the main towline to be cleaned, and then reinstall the screw rod 22 and the guide roller 2 at the opening of the installation body 1, so that the device is sleeved on the main towline. Connect the external high-pressure water pipe to the connecting steel pipe through the quick connector 42, and then use at least two thin ropes to tie them from both sides of the installation body 1, and fix the other end of the thin rope on the deck to prevent the device from moving with the main towline when the main towline is retracted. Finally, turn on the high-pressure water pump, and the high-pressure nozzle 31 on the annular cavity 3 will discharge water to start the three-dimensional flushing of the main towline. As the main towline is retracted, the device can automatically and comprehensively flush the entire main towline.
