Device for mounting and removal of the fairing on the cable tow 1, connecting the onboard research equipment with ship devices and sources of electricity, contains guide rollers 2, on which the cable tow 1 with the fairings 3.

Tape fairings 3 in the area between the equipment and the device is worn, fixed and closed around the cable tug 1. Vertical, freely rotating forming rollers 4 are installed in pairs relative to the line of the cable tug 1.

On the former 5, guide rollers 2 and shaping rollers 4, 6, 7, 8 and 9 are mounted. Rollers 6, 8 and 9 have a profile with increasing taper towards the winch and are elements that form the profile of the tape fairings 3.

The rollers 10 and 11 are supporting and guiding for the cable wheel 1, coiled up or wound around the winch drum 12.

Through, for example, the chain transmission 13, the winch drum 12 is connected to the reel drum 14. On the drum 12 of the winch, the tug 1 cable is wound in several layers, and a tape of the fairings 3 is wound on the drum 14 of the tape in a spiral of Archimedes. The roller 15 supporting and direction-governing ¹ fairings tape 3, the first forming obtekate profile. ley element.

All of the above elements of the device installed on the deck of the vessel through the frame 16.

To ensure the tension of the tape fairings 3 as in etching,

.so and at-election serves Friction. a coupling 17, which also provides synchronous winding and winding of the tape fairings 3 on the reel 14 of the drive bag. This is necessary in order for the cable-tug 1 and the tape of the fairings 3 to pass through the imaging unit 5 at the same speed without “reciprocal slippage”. Rostow clutch 17 of the leading 18 and still _s drives and supports the reel 19. For fixing the tape fairings 3 during towing equipment on the cable tow 1 installed brand 20, the mating corresponding slots of the tape fairings 3.

At the peripheral walls of the fairing 3 installed cord 21 or elastic. strip. For the stability of the tape fairing 3 in cross section

grooves and protrusions 22 are provided, and for connecting (closing) the tape of the fairings after folding around the cable-tug 1, there are locks consisting of a rod 23 with a head and an elastic socket 24. In this position, the heads of rods 23 are fixed in elastic sockets 24. Shanks 25 Fairings, depending on the speed of movement and degree of stabilization in water, have different outlines.

The device works as follows.

The device can be used in two modes of operation: etching the cable-tug 1 with the tape of the fairing 3 and their selection.

In the pickling mode, the winch with a drum 12 is activated on the baiting, the cable-tug 1 starts rolling (winding) and the latter, due to the rotation of the drum 12 clockwise, begins to wind off.

Due to the mechanical connection of the drum 12 of the winch with the drum · 14 drive view through the clutch transmission 13, the disks 18 of the Friction clutch 17 begin to rotate. However, due to the fact that the clutch 17 from the drum 14 of the driving view is disabled, its chain transmission 13 will not rotate. Since the tape of the fairing 3 is mechanically connected to the cable-tug 1 outside the shaper 5 by means of locks and marks, 20, when winding the cable towing vehicle 1 is carried away and the tape of the fairing 3 from the reel 14 of the drive lining, overcoming the resistance of the Friction clutch 17 connected to the support · 19 views. Thus, Kabulbuksir 1 and tape fairing 3 synchronously fed to the imaging unit 5, having previously passed guide rollers 11 and 10 (for the cable-tug) and 15 and 9 (for the tape fairing).

¹ Reeling off the reel 14 of the drive view in the unfolded (flat) state, the tape of the fairings 3, due to the presence of a cord 21 or elastic bands in it, tends to approach the shanks 25, i.e. folding profile. With the passage of the tape fairing through the rollers 7 with a y-shaped arrangement of the axes, a certain angle of collapse of the tape of the fairing 3 is maintained. and grooves closes, and the rods, 23 with the heads are included in the elastic nests 24, making the closure of the required profile of the tape fairings 3. as far as feeding cable ^ towing system (cable-tug 1 5

tape wrappers 3) on the etching system, passing shaper 5, · continuously wraps and closes around the cable tug 1, ensuring the fixing of the fairings on the cable tug.

Mode. the selection is as follows.

The winch with the drum 12 is included in the selection (winding) of the cable wheel. 1, and the latter due to the rotation of the drum 12 of the winch counterclockwise starts to wind on it.

Due to the mechanical connection of the drum 12 of the winch with the drum 14 of the drive bag by means of a chain transmission 13, the driving disks 18 of the friction clutch 17 connected to the drum 14 of the drive bag begin to rotate. If the cable-tug ί and the tape of the fairings 3 go to the winding, and their winding diameters are different, their speeds of movement will also be different. Considering that the speed of rotation of the drum 14 of the drive rack is chosen higher than the speed of rotation of the drum 12 of the cable-tug 1, and the cab-tug 1 and the tape of the fairings 3, due to the locks and marks of 20, move synchronously, then this synchronism is achieved by winding the tape of the fairings 3 on the reel 14 of the power drive under tension with slipping of the friction clutch 17, which is set to allowable tension in the tape of the fairings 3. Revolving to select, the winch drum 12, which drives the rotation and the reel drive 14, provides winding Information on both tug 1 cable and fairing tapes 3.

When the tape moves, the Fairings 3 together with the cable-tug 1 for selection, closed on the section to the former 5 and on the section of the guide rollers 4 of the former 5, the towing system encounters two rollers 7 with a Y-shaped arrangement of the axes of rotation installed in the camber of the fairings 3. Since the tape of the fairing goes to the winding on the reel 14 of the drive view, the rollers 7, meeting the closed tape, part it, removing the tailings 25 of the tape of the fairing from each other, opening the locks, removing the rods one by one

23 with heads made of elastic sockets 24. Since the reel 14 of the drive view accepts a flat unfolded tape of the fairing, the closer the ribbon passes to the reel 14 of the drive

5 views, the more becomes the angle of opening of the profile of the tape fairings. To ensure the passage of the tape fairings 3 on the drum 14 of the drive view, rollers 8, 9 are installed.

10 and 15. Thus, having passed through the process of choosing the shaper 5 and the system of guide rollers, the tape of the fairing 3 is removed from the cable wheel and 1 is wound onto the drum
