Description

This invention relates to a communal household, primarily for cleaning pipes.

A device for pulsed cleaning of the internal surface of pipelines is known, comprising floors and a casing with reactive inclined nozzles, the outlet openings of which are evenly circumferentially centered on the axis of the device, connected to the casing of the nozzle for connection of the working jets through the hose to the source of the working agent.

The disadvantage of the device is the complexity of the design.

A device for electro-hydraulic cleaning of products is known, consisting of electrodes, a battery of capacitors with a voltage and a charging device.

The disadvantage of the device is the limited use for cleaning sewer pipes, since it is difficult to transport the device in the pipe to the location of the created plug.

An electrical discharge device is known, which contains a current pulse generator, a cable, a housing with conical reflectors and electrodes, the conical reflectors face apexes in the direction of the movement of the device, the lower conical reflector, in the center of which one of the electrodes is located, is formed by the bottom of the case, and the upper conical The reflector is formed by a housing cover, in the center of which another electrode is placed.

The drawback of the device is; low productivity and inefficient cleaning quality.

The purpose of the invention is to improve the quality and performance of cleaning.

This target is achieved by the fact that the electric discharge device for cleaning

the internal surface of the pipelines containing two coaxial electrodes, the first of which is installed along the axis of the reflector, and a pulsed current source connected to the electrodes, о о contains an additional ring electrode mounted in the conical part of the reflector flush with its side surface, and the second of the main electrodes is made in the form of a sleeve with conical end grooves, covering the first electrode, mounted one end on top of the conical part of the reflector with a gap forming an annular channel for liver moving device.

The pulsed current source is made up of two arresters connected to capacitor banks.

Comparative analysis of the proposed technical solution with the prototype allows to establish the novelty of their criteria, since the additional electrodes with a capacitor battery and the execution of the discharge gap in the form of a nozzle allows transforming the blast energy into the energy of moving the working body along the pipeline in fusing. When studying other known technical solutions in this field of technology, the signs that distinguish the invention from the prototype have not been identified and therefore they provide: with the proposed technical solution, the criterion of essential differences.

The drawing shows a General view of the device.

The device consists of two coaxial electrodes 1,2, an additional electrode 3 mounted in the conical part of the reflector 4 flush with its side surface. The electrode 1 is mounted along the axis of the reflector, and the electrode 2 is made in the form of a sleeve with conical end grooves covering the electrode 1. mounted with one end on top of the conical part of the reflector A with a gap forming the annular channel 5 to ensure movement of the device. The electrodes 1,2,3 are connected by cable 6 to a pulsed current source 7 consisting of two arresters 8.9 and capacitor batteries 10.11.

The device is immersed in water. When applying a series of pulses from a battery of capacitors 11, the reactive force from the shock waves moves the device in the pipeline to the point of clogging (not shown). Current pulses are then applied simultaneously.

from batteries 10.11 on both pairs of electrodes 1,2 and 2,3. In this case, the shock wave from the main pair of electrodes 1.2 destroys and pushes the blockage, and the reactive force from the pair of electrodes 2.3 reduces the recoil.

The proposed device is simple in construction and significantly effective compared to known devices. The device prevents the destruction of the pipeline made from brittle

material, for example, ceramic, which expands its technological capabilities.
