Description

This utility model relates to the field of municipal engineering, namely to working equipment for cleaning the internal cavity of pipelines.

Known prototype, "Device for cleaning the internal cavity of the pipeline" Patent for invention No. 2405635, 29.01.2009.

The prototype consists (see Fig. 1 and Fig. 2) of the following main components and parts: 1 - head; 2 - nozzles in the head; 3 - fitting; 4 - bottom; 5 - holes for the passage of the working agent (eg water); 6 - shaft; 7 - working body; 8 - blades; 9 - helical gear; 10 - bushing; 11 - bearing; 12 - holes for washing out; 13 - nozzles in the fitting.

The prototype has the following design (see Fig. 1 and Fig. 2)

The head 1 with nozzles 2 is screwed onto the fitting 3, the fitting 3 contains a bottom 4 with holes 5 for the passage of the working agent (eg water). Fitting 3 and bottom 4 are made as a single piece. On the shaft 6 is the working body 7 with blades 8 (see Fig. 1), the working body 7 can be made in the form of a helical gear 9 (see Fig. 2) the working body 7 may have other designs.

Shaft 6 is mounted on bushings 10 in head 1 and in bottom 4 of fitting 3. Shaft 6 can also be mounted on bearings 11 (see Fig. 2). The holes 12 in the head 1 are designed to wash out the removed contaminants.

To perform work on cleaning the internal cavity of the pipeline, the prototype is screwed onto the thread of the fitting 3 using a pipe (conditionally not indicated), connected to a hose for supplying a working agent (for example, water).

The prototype works as follows (see Fig. 1 and Fig. 2).

The working agent (for example, water) under pressure from the fitting 3 through the holes 5 enters the blades 8 (see Fig. 1) of the working body 7 or helical gear 9 (see Fig. 2), driving the shaft 6 with a tip (conditionally not marked) acts on the resulting blockages, which allows you to clean the pipeline from various deposits.

Escaping through the nozzle 2 (see Fig. 1) or nozzle 13 (see Fig. 2), the working agent (eg water) creates jet thrust and moves the device forward. The rotating tip (not conventionally marked) separates hard and dense deposits with its cutting edges, which are distilled off by jet streams and transported along the cleaned pipe.

The prototype has the following disadvantages.

In the prototype (see Fig. 1) in the sleeve 10 there is no hole for lubricating the rotating shaft 6 with a working agent (eg water). When exposed to a working agent (for example, water) through holes 5 on the blades 8 (see Fig. 1), the shaft 6, rotating longitudinally, presses on the sleeve 10 in the head 1, which leads to rapid wear of the sleeve 10.

When the shaft 6 rotates (see Fig. 2), water penetrates into the closed bearings 11 and they begin to rust, it is often necessary to change the bearings.

In the manufacture of the head 1 (see Fig. 2) have to drill holes of great length. Since the head is made of durable steel, drilling takes a lot of time.

The tasks to be solved by the claimed utility model are: simplification of the design of the device; minimizing device maintenance; improved reliability and extended life of the device.

These tasks are solved due to the fact that in the claimed device for cleaning the internal cavity of the pipeline (hereinafter referred to as the device) containing the head, bushing, fitting, shaft, a distinguishing feature from the prototype is that the head has a bushing with holes for lubricating the shaft, in which a thrust a bearing against which a shaft rotates in a bushing.

The technical result that provides the above set of features is: minimization of maintenance; simplification of the design; increased reliability; extension of service life.

The drawing (see Fig. 3 and Fig. 4) shows a General view of the device for cleaning the internal pipeline, schematically in longitudinal section.

Position in the drawing (see Fig. 3 and Fig. 4) denote: 14 - head; 15 - nozzles in the head; 16 - fitting; 17 - the bottom of the fitting; 18 - holes in the bottom of the fitting; 19 - shaft; 20 - working body; 21 - blades; 22 - helical gear; 23 - sleeve; 24 - bearing; 25 - openings for the outlet of the working agent of the spent working agent; 26 - nozzles in the fitting; 27 - holes for the passage of the working agent; 28 - holes for supplying a working agent for lubricating the shaft.

The device has the following design (see Fig. 3 and Fig. 4).

A sleeve 23 is placed in the head 14 with holes 25 for the exit of the spent working agent (for example, water), into which the bearing 24 is mounted. The sleeve 23 has holes 27 for the passage of the working agent (for example, water) and holes 28 for the passage of the working agent (for example, water) for lubrication of the shaft 19. A shaft 19 is inserted into the sleeve 23, equipped with a working body 20 with blades 21 (see Fig. 3), the working body 20 can be made in the form of a helical gear 22 (see Fig. 4), the working body may have and other performances. Shaft 19 is equipped with a tip (conditionally not marked). A fitting 16 with nozzles 26 is screwed to the head 14. The fitting 16 has a bottom 17 with holes 18 for supplying the working agent (for example, water) to the working body 20 of the shaft 19.

To perform work on cleaning the internal cavity of the pipeline, the device is connected to a hose for supplying a working agent (for example, water) using a pipe (conditionally not indicated) screwed onto the thread of the fitting 16.

The device operates as follows (see Fig. 3 and Fig. 4).

The working agent (for example, water) enters the nozzle 16 under pressure, then flows out of the nozzles 26 and creates jet thrust and moves the device forward along the pipeline, while through the holes 18 in the bottom 17 of the nozzle 16, the working agent (for example, water) acts on the working body 20 in the form of a helical gear 22, causing the shaft 19 to rotate. The working agent (for example, water), having worked out on the working body 20 of the shaft 19, moves through the holes 27 in the sleeve 23 and through the holes 28 enters under pressure on the shaft 19, lubricating it during rotation, preventing wear of the sleeve 23 and shaft 19. Shaft 19, rotating , abuts against the bearing 24, preventing abrasion of the sleeve 23. The spent working agent (for example, water) breaks out of the holes 25. The spent working agent (for example, water), escaping from the nozzles 15, creates jet thrust in the head 14.

On the claimed device, working drawings were made, a prototype was made, tests showed: an increase in wear resistance; improving reliability. In comparison with the prototype, the duration of operation of the claimed device has increased, its reliability has increased.
