Abstract

Usage: in towed in the water using the cable underwater systems. The essence of the invention: the fastening assembly comprises a housing for mounting the core 2 and a fastening element for securing the assembly on the movable device. The vibration absorber consists of a casing in the form of curved plates 4 and 5, which form the internal cavity B, in which the housing is fixed. In cavity B, lamellar springs 17 and 18 are installed one after another in pairs and clamps 19 to support core 2. Clamps 19 are spring-loaded on both sides with diametrically mounted tension springs 20 and 21. The ends of the springs are fixed between the plates 4 and 5. The fastening element is located on the vibration damper. 3 il.

WITH

The invention relates to mechanical engineering and can be used in those areas of the technology where cable terminations are necessary, for example, underwater systems towed in water.

FIG. 1 shows the assembly of the end of the cable, the general view; in fig. 2 is a section A-A in FIG. one; in FIG. 3, node I in FIG. 1 (mounting the case on the vibration damper).

The cable end fastening assembly comprises a housing 1 for mounting the cable core 2 and a fastening element 3 for securing the assembly on the movable apparatus, which is a power hole. The cable end fixing unit is equipped with a vibration damper, made in the form of a casing of two curved plates 4 and 5, interconnected by screws 6 and nuts 7. Plates 4 and 5 form an internal cavity B, in which case 1 is fixed by means of a washer 8 and screws 9.

If the cable is designed as a cargo carrying armored armor 10, then a filling compound 11 is placed inside the housing 1, fixing the bent ends of the outer armor wires, sleeve 12, protecting the insulating layer 13, and sleeve 14, around which the ends of the outer armor wires are bent fixed by 15 mark from a thin wire. The position of the primer 11 in the housing 1 is fixed by the nut 16.

If cable 2 does not have outer armor, body 1 can be vulcanized onto cable 2. .. In cavity B, a section of cable 2 adjacent to housing 1 is laid and lamellar springs 17 and 18 are installed one above the other and clamps 19 for supporting cable 2; Clamps 19 are spring-loaded on both sides of diametrically mounted tension springs 20 and 21 located between the leaf springs 17 and 18. The ends of the leaf 17 and 18, as well as the screw springs 20 and 21, are fastened between the edges curved plates 4 and 5 of the casing n With the help of strips 22 and screws 23, and the fastening element (hole 3) is located on the vibration damper.

The mount end of the cable works as follows.

With the aid of the fastening element 3, the attachment point is connected to a floating apparatus, to which the cable is transmitted or relieved. The tension of the cable 2 is transferred to the housing 1, and with the help of the washer 8 and screw 9 to the vibration damper. When the cable oscillates due to hydrodynamic forces or wind, the cable is displaced

Income m to the first clamp 19 located at the entrance to the vibration damper. Displacement of cable 2 is perceived (depending on the direction) or by coil springs of tension 20 and 21 (one of them is stretched; and the other is compressed), or lamellar springs. 17 or 18 (one of these springs deflects). As a result of the action of springs preventing the cable from moving, its amplitude in this

the location decreases. However, some smaller part of the oscillation passes to the next collar 19, where under the influence of springs 17.18, 20 and 21 the amplitude of oscillation decreases even more. So in

where the cable 2 is inserted into housing 1, there are practically no oscillations.

Form at l. A. Invention A cable end attachment assembly comprising a housing for sealing a cable core

and a fastening element for securing the unit on the movable apparatus, characterized in that, in order to increase durability and reliability of fastening by reducing vibrations of the end of the fixed cable core, it is equipped with a vibration damper, made in the form of a casing of two curved plates interconnected, plate springs, installed in the cavity of the casing sequentially in a row and in pairs one above the other, as well as clamps to support the cable, spring loaded on both sides of diametrically mounted helical springs of the same neither located between each

a pair of plate springs, with the ends of the plate and coil springs secured between the edges of the curved casing plates, the housing for sealing the cable core is fixed inside the casing between its

curved plates, and the fastener is located on the vibration damper.
