Description

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

A known prototype, "Device for cleaning the internal cavity of the pipeline" Patent for IZ No. 2377080 date publ. 06.06.30.

The prototype "Device for cleaning the internal cavity of the pipeline", Patent No. 3277080, priority June 30, 2008 consists of (see Fig. 1) of: 1 - tip; 2 - cutting edges of the tip; 3 - shaft; 4 - rolling bearings; 5 - a reaction chamber; 6 - holes emerging from the jet chamber; 7 - turbine chamber; 8 - a device for rotating the shaft; 9 - pressure chamber; 10 - pipe; 11 - holes for supplying water under pressure to the device for rotating the shaft; 12 - jet nozzles; 13 - washer; 14 - a neck of a shaft; 15 - spiral groove.

The prototype has the following performance (see Fig. 1).

The tip 1 with cutting edges 2 is screwed onto the shaft 3. The shaft and its neck 14 are mounted on rolling bearings 4. The bearings are pressed by washers 13.

The turbine chamber 7 is made in the form of a hollow cylinder onto which a reaction chamber 5 with holes 6 is screwed. A pressure chamber 9 with reaction nozzles 12, with a pipe 10 is screwed onto the turbine chamber 7.

In the turbine chamber there is a device 8 for rotating the shaft 3.

A spiral groove 15 is made on the shaft.

To perform work on cleaning the internal cavity of the pipeline, the device is connected to the working agent supply hose using a fitting (not shown conventionally), screwed onto the thread of the pipe 10.

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

A working agent (for example water) under pressure from a nozzle 10 enters the pressure chamber 9, through the holes 11 it enters the turbine chamber 7 to the device 8, turning the shaft 3 and the tip connected to it 1. The working agent (through the jet nozzles 12) water, for example) creates jet propulsion and propels the device forward. Next, the working agent (eg water) enters the reactive chamber 5, flowing out through the openings 6, erodes the destroyed deposits by the tip 1 rotating with a high speed.

The shaft 1 during operation of the device rotates at a higher speed of 15-20 thousand rpm, the spiral groove 15 works like a screw, effectively throws out and prevents the ingress of liquid and solid fractions, such as sand, from the pipe cavity being cleaned into the rolling bearings of the device.

The prototype has the following disadvantages.

When the prototype is working, the shaft 3 with bearings 4 (see Fig. 1) rotate at a speed of 15-20 thousand rpm in an aggressive environment of the working agent (for example, in water). Over time, a working agent (for example water) penetrates the bearings 4 and renders them unusable, as a result of which the prototype requires daily lubrication and periodic replacement of bearings, which is also associated with the necessary availability of special tools and devices.

During the operation of the prototype, a rotating shaft 3 with a tip 1 (see Fig. 1) is able to act on fractions that clog the internal cavity of the pipeline only in its longitudinal direction, which does not allow for complete cleaning of the pipeline, including fouling on its walls.

The tasks to be solved by the claimed utility model are: simplification of the design of the device; Minimizing device maintenance increasing the degree and quality of cleaning the internal cavity of the pipeline, including fouling on its walls.

These tasks are solved due to the fact that in the inventive device for cleaning the internal cavity of the pipeline (hereinafter the device), containing the pressure and vortex chambers, the cover of the vortex chamber, the shaft, a distinctive feature of the prototype is that the turbine chamber is replaced by a vortex chamber with a radially grooved chute , which gives the shaft not rotational, but circular motion transmitted from one end of the shaft to the other using a ball joint that excludes bearings from the structure.

The technical result provided by the given set of features are: simplification of the design; minimization of service; increasing the degree and quality of cleaning the internal cavity of the pipeline, including fouling on its walls; the acquisition of additional functions and the expansion of the scope of the device.

The drawing (see Fig. 2) shows a General view of a device for cleaning the internal cavity of the pipeline, schematically in longitudinal section.

Position in the drawing (see Fig. 2) indicate: 3 - shaft; 9 - pressure chamber; 12 - jet nozzles; 16 - swirl chamber with a radial groove; 17 - holes for supplying the working agent to the radial groove of the vortex chamber; 18 - cover of the vortex chamber; 19 and 20 - openings for the exit of the spent working agent; 21 - holes for lubrication and washing from contamination of the ball joint by the spent working agent; 22 - ball joint.

The device has the following design (see. Fig. 2).

The pressure chamber 9 with the jet nozzles 12 is screwed onto the vortex chamber with a radial groove 16. In this case, an internal gap is provided between the bodies of these chambers for the working agent (for example, water) to pass through the holes 17 into the radial groove of the vortex chamber 16. It is inserted into the radial groove of the vortex chamber 16 a shaft 3 with a ball joint 22 and holes 21. The cover of the vortex chamber 18 is screwed into the vortex chamber 16 with openings for the outlet of the spent working agent (eg water) 19 and 20. In the screwed state, the cover of the vortex chamber 18 fixes the ball joint 22 of the shaft 3 in its housing so that a small clearance remains for free rotation of the ball joint.

To perform work on cleaning the internal cavity of the pipeline, the device is connected to the hose for supplying a working agent (for example, water) with the help of a fitting (not indicated), screwed onto the thread of the pressure chamber 9.

The device operates as follows (see Fig. 2).

A working agent (e.g. water) is pressurized into the pressure chamber 9, then flowing out through the jet nozzles 12, a working agent (e.g. water) creates a reaction rod and propels the device forward through the pipeline. At the same time, through the holes drilled at an angle 17, the working agent (for example water) enters the vortex chamber 16, where it acts on the shaft 3, forcing it to move along the radial groove of the vortex chamber 16 and make a circular motion. The circular motion of the shaft 3 in the vortex chamber 16 is transmitted through a freely rotating ball joint 22 to the opposite end of the shaft 3 with a tip screwed onto it (not indicated). The working agent (for example, water) that has worked in the vortex chamber 16 exits through the openings 19 and 20 of the lid of the vortex chamber 18, washing away deposits in the pipe being cleaned and lubricating and washing the ball joint from dirt through the holes 21 of the shaft 3.

Due to the circular motion, the shaft 3 with a tip screwed onto it (not indicated conventionally) acts on the walls of the pipeline, which allows it to effectively clean its walls of solid fouling.

On the claimed device made working drawings, made and tested a prototype. Tests have shown high efficiency in cleaning sewer pipelines from greasy fouling.

In comparison with the analogue, the productivity of the claimed device increased, its reliability increased.
