Description

I

The invention relates to shipbuilding, in particular to devices for fastening and recoil of an underwater object.

A known tension crust for coastal apparatus containing dead measles and breedel consisting of two parts. The first part of the bridle is connected by a bracket to a dead bark, equipped with tanks with positive buoyancy, which ensure the constant tension of this part of the bridle. The second part of the tub is intended to be connected to a submerged apparatus, freely suspended from the first part 1.

The disadvantage of this device is that the buried object cannot be completely submerged in water, since its burial mechanism is located on the buried object and is not designed to work in the submerged position.

The closest technical solution to the present invention is a device for mounting and releasing a brigade of an underwater object, comprising a hollow body connected to the bottom ballast and interacting with a connecting link associated with the underwater object, as well as elements for wiring the cable for recessing 2. The disadvantage of this device is is the possibility of self-denial. The purpose of the invention is to increase the reliability of the device and simplify its maintenance.

This goal is achieved in that the connecting link comprises a cylindrical body made with an opening and equipped with a ring, to which the arresters passing through the body opening are attached so that they can rotate around an axis, equipped with recoil cables and a cartridge, and the arresters are connected to the recoil cables that are attached in the cartridge, and on the inner surface of the upper part of the hollow body there is an annular stop interacting with the arresting devices.

FIG. 1 shows the device section; 20 in FIG. 2 - the same, top view with partial cut; in fig. 3 is a diagram of the staging (removal) of an underwater object to measles.

The attachment and recoil device of the underwater object consists of a connecting

link 1 connected to the breeze 2 of the underwater object 3 by the clip 4, and the reciprocating clutch assembly 5 mounted on the core b and having a hollow body 7 with an annular abutment 8 in the upper part. In the lower part of the hollow body 7, test two butts 9 for attaching to the rod b and cable guides 10.

Link 1 is made in the form of a ring 11, on which with the help of butts 12 and axes 13 fixed freely tiltable front portions of their own weight move the arresters 14. Ring II has a butt 15 for attachment to breeder 2. Link 1 is enclosed in a cylindrical body 16 with a conical bottom, to which is attached an eye 17 for fastening the cable 18 for burial using a carabiner 19. To the movable delays 14 there are fixed recoil cables 20, brought out through the lower opening in the cylindrical body 16 to the outside and fixed in the cartridge 21.

The device is attached and recoil breeders underwater object works as follows.

The reciprocal coupling unit 5, with its housing 7, is fastened to the eye of the core b with the aid of a bolted connection through the buttles 9, lowered together with the bark 6 and the depth control cable 18 to the bottom and is permanently located with it. To the breeder 2 of the underwater object 3, delivered to the place of installation on the ship, fasten the connecting link 1 for the butt 15 with the lifting bracket 4.

The root end of the cable 18 of the burial, passed through the cable guides 10 and the hollow body 7, is fastened with a carbine 19 to the eye 17. The travel end of the cable 18 of the burial is turned on the winch of the vessel with which the underwater object is positioned.

Underwater object 3 is given a positive buoyancy, and with the aid of the ship's winch and cable 18, the depth is lowered to the bottom. The movable arresters 14 are in the folded-down state under their own weight.

When approaching to the reciprocal coupling unit 5, the link 1 by the conical bottom part enters the ring stop 8, the movable delays 14 rest against the edges of the ring stop 8 and during the subsequent movement of the link 1 down under the action of the force of the cable 18, they turn around the axes 13 and retract inside the cylindrical housing 16, and thereby allowing link 1 to reach the lower position.

Passing the ring stop 8, the movable arresters 14 under the action of their own weight fold back and out of the cylindrical housing 16. Thereafter, the tension of the cable 18 is reduced, and under the action of the buoyancy force, the underwater object 3 emerges, while the movable arresters 14 abut ring stop 8 and thus the statement of the underwater object 3 on measles 6.

Removal of the underwater object from the core is carried out as follows.

The cable 18 of the burial is overrun by the cartridge 21. The underwater object 3 is buried by the ship's winch using the cable end of the cable 18 of the burial. Under the action of mutually opposite forces (the buoyancy force acting upwards and the depth force directed downward), link 1 is lowered (with a depth force greater than

buoyancy), moving the movable delays 14 inside the cylindrical body 16 with the help of cables 20 and the free exit of the link 1 from the body 7 of the reciprocal coupling unit 5 when the buoyancy force exceeds the burial force (when traversed

the end of the cable deepening). In all cases, the movable arresters 14 are retracted into the cylindrical body 16, since the penetration and buoyancy forces act in different directions. By further aggravating the running end of the cable 18, the underwater object 3 rises to the surface.

Semi-automatic device for attachment and release of bridges to an underwater object

It is used to fasten the underwater storage tank of petroleum products to the core and allows the installation of the reservoir to the bark without the diver’s participation, since the coupling of the device to the reservoir breeder with the bark response node is performed automatically, eliminating completely the possibility of the spontaneous recoil of the reservoir from the core. In addition, it is possible to minimize the labor of a diver when taking pictures of a tank with a bark and to carry out maintenance of the connecting link when the tank is raised to the surface to inspect it, and the response node does not need to be serviced in a submerged position.
