Description

The invention relates to space technology, in particular to equipment for ensuring work in space conditions, namely, devices for stacking, securing, transporting and laying out flexible, lengthwise elements, for example, cables, hoses, cables, halyards, an astronaut in a spacesuit on the surface of space objects or celestial bodies. In addition, the device can be used in terrestrial conditions and during underwater technical work.

A device for accommodating an extension cable containing a coil in the form of a cylinder with two end disks and a cable wound on the cylinder ending in connectors [1] is known.

The disadvantages of this device are the difficulty of operating it by the operator in a spacesuit, the inconvenience of using existing means of fixation and orientation of the device with respect to the cable being unwound in zero gravity, the relatively low level of cable protection from possible damage, the inability to check the integrity of the conductors entering the cable without fully reeling drum.

A device is known, taken as a prototype, containing a coil in the form of a cylinder with two end disks, with a cable wound around the cylinder, terminated with connectors, provided with a latch and mounted on the frame, the frame is made of rods forming a closed loop and covering the coil with cable and connectors, the fixing element of the handle of one of the connectors is made in the form of a longitudinal recess on the surface of the cylinder, combined with a cutout on the end disk, and the fixing element of the other connector is located on the inside of the electric ment of the frame parallel to the axis of rotation of the coil, the coil axis of rotation is mounted on the frame with an interference fit. [2]

In the method according to the technical solution [2], a flexible element extended along the length is placed in coils on a coil. A prototype for the proposed method was not found.

The disadvantage of this device is the need for delivery to a space object of a new frame with a coil and cable. In addition, when unwinding from a reel, the cable retains the shape specified by the reel, collapses into rings, which makes it difficult to lay and creates a risk of damage when stretched. Winding the cable from the reel takes a relatively long time in the process of extra-ship activity, as a result of which the length of stay of crew members in outer space increases.

The objective of the invention is the creation of an ergonomic and portable device in relation to the astronaut, especially equipped in a spacesuit, by ensuring the integrity of the flexible element extended along the length, ease of fixing, transportation and layout on the outer surface of the space object.

The problem is solved as follows.

A device is proposed that contains a supporting structure in the form of two plates fastened with a connecting strip, racks are installed perpendicular to them at equal intervals at the periphery of the plates, on the outer surface of which brackets are fixed in two parallel rows perpendicular to the rack, while on the plate opposite each rack is installed emphasis, forming between the brackets and the rack space for laying a flexible element extended along the length.

A method of operating a stacking device for a flexible element extended along the length in space conditions involves placing a flexible element extended along the length of the element in tiers in the form of the number "8" on the brackets in the space between the uprights and stops.

In FIG. 1 - Plate assembly.

In FIG. 2 - Stand assembly.

In FIG. 3 - Cable laying;

In FIG. 4 - The device assembly without a flexible element extended along the length (isometry);

In FIG. 5 - Stand assembly (three-dimensional image);

In FIG. 6 - Assembly of the device (three-dimensional image);

In FIG. 7 - An experimental sample of the device.

In the figures:

1 - plate;

2 - a connecting level;

3 - rack;

4 - bracket;

5 - emphasis;

6 - flexible element extended along the length.

The proposed device consists of plates 1, fastened by a connecting strap 2, with racks 3 and stops 5 mounted on the periphery of the plates 1, as well as brackets 4, mounted on racks 3 in two rows.

Method of operation of the device: the plates 1 are fastened using a connecting strip 2, the cable 6 from the bay is laid in tiers in the form of the number "8" on the brackets 4 in the cells between the uprights 3 and the stops 5.

This invention allows to create an ergonomic and portable device for an astronaut, especially equipped in a spacesuit, by ensuring the integrity of a flexible element extended along the length, ease of fixing, transportation and layout on the outer surface of a space object, which is confirmed by the positive results of tests of a prototype in space conditions and reviews of astronauts.
