Description

The utility model relates to industrial protection, in particular to environmental protection when working with aggressive media.

In the prior art, a protective cover for a duct or expansion joint flange is known (CN 205331710 dated 2016-06-22). The protective casing contains the first (upper) and second (lower) covers of a cylindrical shape, having fastening systems for interconnection. The disadvantage of this design is the connection of the upper and lower parts of the casing from the outside, which is not reliable and tight.

The closest in technical essence is a device for collecting liquid from a pipeline (RU 147229, published: 10/27/2014 Bull. No. 30), which is a semi-cylindrical box made of sheet metal, on the side walls of which semicircular grooves are made on one axis, providing the possibility of tight semi-cylindrical box to fit the body of the pipeline, on the edges of the arcuate base of the semi-cylindrical box there are l-shaped protrusions that provide the possibility of attaching suspension cords to them, while the arcuate base of the semi-cylindrical box has a through hole, in the area of which a metal tube is fixed for connecting a drain hose to it liquid collected from the pipeline. The disadvantage of this device is that it is semi-cylindrical, which does not provide full protection against splashing of the medium flowing through the pipeline if it is damaged.

The task to be solved by the claimed utility model is to develop a device that protects against spillage of the medium in case of damage to the pipeline.

This problem is solved by the fact that the protective collector for the straight section of the pipeline consists of the lower and upper shells connected to each other, end caps are installed along the edges of the collector, fixed with a lock connection, for installing the collector on the pipeline and connecting the upper and lower shells, there are centering mounting plates repeating the contour of the collector along its outer edge and the contour of the pipeline along the inner edge, consisting of the upper and lower parts interconnected by bolted joints, while the lower part of the centering plate is welded to the lower shell of the collector. The upper part of the centering plate has a ledge that repeats the shape of the pipeline. The protective manifold for the straight section of the pipeline is made of steel, or black steel, or coated black steel, or galvanized steel, or coated galvanized steel, or stainless steel, or chemically resistant plastics or polymers.

The technical result provided by the given combination of features is the reliable retention of the collector on the pipeline. An additional technical result can be considered the expansion of the arsenal of technical means, namely protective collectors.

The protective collector for the pipeline is intended mainly for straight sections of pipelines. The device is intended for single pipelines or for a complex of nearby parallel pipelines.

The protective collector is used to collect and divert leaks of the pumped medium in case of pipeline depressurization. Protective collectors are installed in places above the passage of people, the passage of equipment and provide protection against spills (splashing) of chemical reagents in case of depressurization of pipelines.

The claimed utility model is illustrated by drawings, which show:

- in Fig. 1 - general view of the device,

- in Fig. 2 - view of the device without the upper shell,

- in Fig. 3 is a view of the device section.

The protective collector consists of two parts: lower 1 and upper 2 shells, made in the form of a gutter, interconnected into a single structure by assembly operations, namely, self-tapping screws, or locking joints, or bolted connection, or any other similar method. To install the collector on the pipeline and connect the upper and lower shells, there are centering mounting plates 3 on the inside of the collector, repeating the contour of the collector along its outer edge and the contour of the pipeline along the inner edge. Centering mounting plates consist of two parts: upper and lower, made semicircular. The lower part of the centering plate is welded to the lower shell of the manifold. The upper part of the centering plate is bolted to the lower part. The upper shell is laid on the upper part of the centering plate and connected to the lower shell. For a more dense installation of the collector on the pipeline, the upper part of the plate has a protrusion 4, which repeats the part of the pipeline. The size of the plate is selected in such a way that it is tightly attached to the pipeline. The number of plates can be more than two and depends on the length of the collector.

The lower shell is mounted on the pipeline using a centering mounting plate. The lower shell is closed by the upper shell. This design is closed with an end cap at both ends of the insulated section.

Along the edges of the collector, consisting of the upper and lower parts, there are end caps 5. The end caps follow the shape of the manifold and pipeline. The end caps are attached to the collector by means of a locking (folded) connection 6.

The pipeline can be covered with a collector consisting of several segments, depending on the length of the insulated section. In FIG. 1 shows a variant of pipeline protection, including several segments: initial 7 and closing 9 segments, and between them the required number of segments 8 is inserted depending on the length of the insulated section. The segments are interconnected by means of a lock (folded) connection.

One of the segments, most often the initial segment, is equipped with an emergency drain fitting, which allows the leakage product to be drained to a safe place.

The protective collector for a complex of nearby parallel pipelines may have a round, oval (ellipse) or rectangular cross-sectional shape. The size and shape of the plate depends on the number and diameters of the pipelines.

The protective manifold can be made of steel, black steel, coated black steel, galvanized steel, coated galvanized steel, stainless steel, chemically resistant plastics or polymers.

The upper and lower shells of the collector are put on over the pipeline, connected to each other and closed with end caps. Sealing of seams at the junction of sections is carried out using an acid-resistant sealant.

Thus, the collector fixed on the pipeline protects against splashing or leakage of the medium moving through the pipeline in case of damage. The collector ensures the collection of the flowing medium and its removal from the collector.
