Abstract

The invention relates to the mining industry and the public sector, where the need arises for laying flexible pipelines. Dov. The goal is to increase the range of self-laying. For this, along the outer surface of the invertible part of the AL 10 8 1Z 7/11 flexible pipeline (TP) 5, the flexible element is made with a pocket (k) 12, inside of which are labyrinth partitions. Positioned K 12 at half cross section of flexible TP 5. Air flow from pneumatic power source 1 enters pipe 2, and TP 5 begins to turn inside out under the action of excessive air pressure, exit cassette 4 through slots 9 and 3 and apply on emergency mining soil . After TP 5 is laid at a predetermined length, a pump, a liquid, for example, water, is supplied to K12. The fluid moves its volume and, that is, the sheath weight of the TP 5. weight, the sheath of TP 5 moves air from the folds of the sheath and moves it towards the source 1 pneumosnergia. 7 il. 1Z 7 / in to 12, the filling increases by the most.

Description

The invention relates to areas of national economy, where the need arises for laying flexible pipelines, can be used in conditions of an atmosphere that is dangerous for human habitation, for example, during emergency operation in mines and is an improvement of the invention according to the author. No. 1368440.

The purpose of the invention is to increase the distance of self-laying.

FIG. 1 shows a device for self-laying of a flexible pipe at the time of laying, a general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4- removal of air from the shell when the pockets are filled with water; in FIG. 5 —the device at the moment of air supply to the untapped part of the flexible pipe after the air has been removed from the shell; in fig. 6 shows a section B-B in FIG. five; in fig. 7 - pipeline at the time of availability.

The device (Fig. 1) consists of a source of pneumatic energy 1 connected to a pipe 2 having a slot 3, a cassette 4 with assembled layers of a flexible pipe 5, the unwrapped end 6 of which is fixed by a clip 7 in the cassette 4, and the inverted end 8 of the flexible pipe 5 is omitted through slots 9 and 3 and secured to the nozzle 2 by a collar 10. Along the outer surface of the invertible part 11 of the flexible pipe 5, the flexible element is made with a pocket 12 (FIG. 1), inside of which are labyrinth partitions 13 (FIG. 3). Pocket 12 is located at half the cross section of the flexible pipe 5 (Fig. 2). The cassette 4 is a container made, for example, of plastic, into which is placed layers, having a cross section in the form of a coil, a flexible pipe 5.

The cassette 4 is connected to the nozzle 2 in such a way that the slot 9 coincides with the slot 3, for example, by means of a quick-lift clamp-type connection (not shown).

The device works as follows. .

The air flow from the source of pneumatic energy (Fig. 1) enters the pipe 2, the flexible pipe 5 under the action of excessive air pressure begins to turn inside out, leaving the cassette 4 (Fig. 1)

through slots 9 and 3 and lay on the soil of the emergency mine workings. After laying the flexible pipe 5 for a predetermined length, a pump (not shown) supplies fluid, such as water, to the pocket 12 (Fig. 4). The fluid, moving in the pocket 12, fills its volume and increases the weight of the shell of the pipeline 5 (Fig. 4). Under the action of the weight force, the shell of the flexible pipe 5 settles, squeezes the air out of the folds of the shell and moves it towards the source 1 of pneumatic energy. To do this, it is enough to fill with water only the pocket 12, located on the inverted part of the casing of the pipeline 5. To simplify the design, the pocket 12 can be made with labyrinth partitions 13 (Fig. 6) only in the first half (invertible part) of the flexible pipeline 5, and on the rest of the flexible pipeline 5 — in the form of a channel 14 (FIG. 5) for supplying water. The water filling the pocket 12 cools the shell of the flexible pipe 5 and the atmosphere of the emergency mining process, since it has a heat capacity of more than four times greater than the heat capacity of air, and also has a lower temperature than air. Therefore, when water is heated through the shell material of the pocket 12, it absorbs a significant amount of heat. Due to the movement of water in the pocket (Fig. 4), it removes its heat from the emergency generation, as a result of which the temperature development of the emergency generation is normalized faster. After filling the pocket 12 with water (Fig. 4), the air is completely removed from the space between the inverted and unwrapped parts of the flexible pipe 5 (Fig. 7), the pressure in the pocket is relieved. Then, the air supply from the pneumatic energy source to the inside of the pocket begins and the water is removed from it. After that, the flexible pipe is ready for operation.
