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 inner surface of pipelines" Patent for utility model No. 113181 2012.02.10.

The prototype consists (see Fig. 1 and Fig. 2) of: 1 stator; 2 passage channel; 3 rotor; 4 supports; 5 cutting knives; 6 calibrating knives; Channel 7 in the stator; Channel 8 in the rotor; 9 nut; 10 seal; 11 groove for installation; 12 branch pipe.

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

The rotor 3 is put on the stator 1 and fixed with a nut 9. A seal 10 is installed in the groove 11. To perform work on cleaning the inner surface of the pipelines, the device is connected using a pipe 12 to the supply hose of a working agent (for example, water).

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

The working agent (for example water) is supplied under pressure to the passage channel 2 in the stator 1. The working agent (for example water) passes through the axial channel 2 through the radial channels 7 of the stator 1 into the rotor 3. Since the channels 8 are angled in the rotor 3, the rotor 3 begins to rotate under the action of the jet. A rotating rotor 3 periodically blocks the holes in the stator 1, as a result of which a water hammer occurs. The frequency of hydraulic shocks depends on the number of channels 7 and channels 8 and rotor 3 revolutions. Water shocks create a pulsating flow of a working agent (for example water), which flushes and destroys congestion, and also promotes axial movement of the device. Sealing the gap between the stator 1 and the inner surface of the pipeline is carried out by the seal 10. The cutting knives 5 and the calibrating bottom 6 during rotation of the rotor 3 clean the inner surface of the pipeline.

The prototype has the following disadvantages.

Using the prototype when cleaning different diameters of pipelines, it is necessary to select a seal 10 corresponding to the diameter of the pipeline, and also use calibrating knives 6 and cutting knives 5 corresponding to the diameter of the pipeline. Therefore, the prototype is not a multifunctional device.

The prototype destroys deposits moving along the pipeline with the help of hydraulic shocks of a working agent (for example, water). Since the prototype does not have a non-return valve, the pump is subjected to hydraulic shock pump supplying working agent (eg water), which leads to wear of the pump and its destruction.

The nut 9 is not fixed not with a stopper, not with a cotter pin. When the prototype moves with the help of hydraulic shocks, a powerful vibration is created and the nut 9 can be unscrewed.

The movement of the prototype using water hammer and the resulting vibration destroys the connection of ceramic pipelines, which will lead to leakage of fecal water into the ground.

When cleaning pipelines clogged with large fractions such as gravel, gravel, broken brick, construction debris, rags, a prototype pushing large fractions forward will create a blockage, and since the seal 10 seals the pipeline at the back, while the passage channel 2 continues to supply a working agent (for example water) , then the pressure will increase in the pipeline, which can lead to depressurization or destruction of ceramic or plastic pipelines.

The presence of a seal 10 serving to seal the gap between the stator 1 and the inner surface of the pipeline does not allow you to remove blurry deposits, throwing them back, and transported with a working agent (eg water) through the pipeline, for example into a well.

The tasks to be solved by the claimed utility model are: simplification of the design; expansion of the range of application; increasing the degree and quality of cleaning the internal cavity of the pipeline; minimization of service.

The tasks to be solved by the claimed utility model are: expanding the range of applications for cleaning the internal cavity of the pipeline; the ability to remove blurry deposits, throwing them back and transporting them through a pipeline, for example into a well, the ability to undergo turns in small diameter pipelines, the ability to clean dilapidated pipelines.

These tasks are solved due to the fact that in the claimed device for cleaning the internal cavity of pipelines (hereinafter the device) comprising, a housing that has reactive openings, openings for supplying a working agent (eg water), to the turbine blades, the turbine equipped with knives, a casing, a head with wash out holes.

A distinctive feature of the prototype is that the inventive device has no seal, calibrating knives, no nut, no rotor with channels.

The inventive device has a turbine with blades, a casing, the housing contains jet nozzles, a head with washing holes, a sleeve.

The technical result provided by the given set of features are: minimization of service; increasing the degree and quality of cleaning the internal cavity of the pipeline; removal of heavy blockages in small diameter pipelines with turns; the acquisition of additional functions and the expansion of the scope of the device.

The drawing (see Fig. 3) shows a General view of the inventive device, schematically in longitudinal section, as an example, the use of the inventive device when the working body 18 is made in the form of a sleeve onto which a working agent (for example water) is supplied through openings 24.

The positions in the drawing (see. Fig. 3) indicate: 13 building; 14 jet nozzles; 15 holes for supplying a working agent (eg water) to the blades; 16 turbine; 17 head; 18 sleeve; 19 knives; 20 blades; 21 casing; 22 cavity in the housing; 23 holes for supplying a working agent (e.g. water) to the head; 24 holes for supplying a working agent (e.g. water) for lubricating the sleeve; 25 wash holes in the head.

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

A turbine 16 is worn on the housing 13, with a cavity 22, and mounted on the housing 13 with a head 17 with wash holes 25. The housing 13 has a cavity 22, jet nozzles 14 and openings 15 for supplying a working agent (eg water) to the blades 20 and openings 23 for supplying a working agent (eg water) to the head 17 and openings 24 for supplying a working agent (eg water) for lubricating the sleeve 18, and wash holes 25. The turbine 16 rotates on the sleeve 18. The turbine 16 is equipped with knives 19, blades 20 and a casing 21, which protects the blades 20 from blows during the rotation of the turbine us 16.

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) with a fitting (not indicated), screwed onto the thread of the housing 13.

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

A working agent (eg water) under pressure enters the cavity 22, then flows out through the jet nozzles 14, a working agent (eg water) creates a jet thrust and propels the device forward through the pipeline. At the same time, through the drilled holes 15, the working agent (for example water) enters the blades 20 causing the turbine 16 to rotate on the sleeve 18, to which the working agent (for example water) is fed through the holes 24 for lubricating the sleeve 18. Spent working agent on the blades 20 (for example, water) enters the gap between the casing 21 and the housing 13, creating additional reactive traction and eroding deposits.

A working agent (for example water) through the hole 23 enters the head 17 and breaking out through the holes 25 actively erodes deposits, both in front and around the circumference.

Due to the rotation of the turbine 16 equipped with knives 19 and the front erosion of deposits through openings 25 in the head 17 with a working agent (e.g. water), the claimed device effectively cleans the internal cavity of the pipeline, and also when pressure is exerted on the pipe walls by a working agent (e.g. water) from jet nozzles 14 and due to the working agent (for example water) spent on the blades 20 of the turbine 16 and emerging in the gap between the casing 21 and the housing 13, the inventive device effectively cleans the internal cavity of the pipe gadfly. The backward flow of the working agent (e.g. water) additionally creates an injection effect and conveys the eroded deposits through the pipeline to the nearest well.

Drawings are made on the claimed device, a prototype is executed. Tests have shown high efficiency in cleaning sewer pipelines from greasy fouling and heavy blockages in small and large fractions.

In comparison with the analogue, the productivity of the claimed device increased, reliability increased, the scope of application expanded.
