RU2524531C1 - Dismountable polyethylene pipeline for sprinkler sets - Google Patents

Abstract

FIELD: mechanical engineering.

SUBSTANCE: dismountable polyethylene pipeline for sprinkler sets consists of fast-dismountable polyethylene pipes of a distributing pipeline and sprinkler wings. Expandable dismountable clamps with fasteners - hooks with springs and bolts for their tightening on a pipe are installed on the fast-dismountable polyethylene pipes on both ends. A clamp ring on the inner surface has notches, sharp teeth of which are directed towards the pipe end. The ring breadth for each pipe diameter shall satisfy the value B=(0.5…1.0)D, where B - breadth of the clamp ring, D - outer diameter of the polyethylene pipe.

EFFECT: simplification of the structure, assembly, repair and maintenance of the device.

Description

Collapsible polyethylene pipe for irrigation kits refers to agriculture, namely to irrigation kits with portable sprinkler wings, and can be used as part of kits for irrigation of crops in areas of different sizes.

Known srednestruynaya sprinkler SDU-60M, consisting of four working (irrigation) pipelines and one distribution. Working pipelines are completed from sections of polyethylene pipes with clamps with hooks. The pipe sections are connected by steel couplings with connecting loops and sealing cuffs (Sandigursky D.M., Bezrodnov N.A. Mechanization of irrigation works. -M .: Kolos, 1975. -P.32-36).

The disadvantages of the SDU-60M sprinkler are design complexity, low corrosion resistance and high material consumption of steel couplings.

Known portable sprinkler installation of positional action, containing a distribution pipe and sprinkler wings, fittings, shut-off and control valves, sprinklers. Polyethylene pipes with clamps are interconnected by polyurethane double-sided couplings and fixed with brackets inserted into the ears of the clamps on the pipes (RF Patent for Utility Model No. 37589, class A01G 25/09, Bull. No. 13 dated 05/10/2004).

The disadvantages of the sprinkler installation are the complexity of the design and the use of removable brackets that are not connected and not fixed to the pipe or coupling, which leads to a possible loss of brackets during installation, dismantling and transfer.

Known mobile sprinkler irrigation systems, consisting of prefabricated polyethylene pipelines with clamps and sockets.

The clamps have special fasteners, which, when connecting the pipes, are inserted into the grooves of the sockets and pressed by springs (Product catalog for agricultural irrigation. - DIZAYN GROUP, 2009. - P.1-8).

The disadvantage of the design of the pipe connection is the rigid, non-separable design of the clamps with fasteners, which complicates their repair and maintenance during operation, increases material costs, since if the clamp is broken it cannot be replaced by another, and it will be necessary to purchase another pipe.

The aim of the invention is to simplify the design, production and operational assembly, repair and maintenance during operation.

This goal is achieved by the fact that on each pipe of a collapsible polyethylene pipe at both ends are installed removable sliding clamps with fasteners, hooks, inserted into the annular recesses of the couplings, and the collar ring on the inner surface has notches, the sharp teeth of which are directed towards the end of the pipe, and the width of the ring for each pipe diameter must satisfy the value B = (0.5 ... 1.0) D, where B is the width of the clamp ring, D is the outer diameter of the polyethylene pipe.

Figure 1 shows a General view of a polyethylene pipe assembly with clamps; figure 2 - pipe assembly with a sleeve.

A collapsible polyethylene pipeline consists of a pipe 1, at the ends of which removable sliding clamps 2 with ears 3 are installed, on which fasteners 4 with springs are installed.

The inner surface of the clamp ring has notches, the sharp teeth of which are directed towards the end of the pipe (not shown conditionally) and when tightening the nut 5 with the bolt 6, installed in the holes of the ears 7, they cut into a polyethylene pipe. The pipes are connected by a sleeve 8 with cuffs 9, and it has annular recesses 10 on both sides for fastenings-hooks.

The assembly of the pipeline is as follows.

The pipe 1 is laid on the field assembly with clamps 2, a sleeve 8 with cuffs 9 is inserted onto it. The end bends of the fasteners-hooks 4 diverge and fall into the recess 10 of the sleeve 8, from the side of the sleeve installation.

The next pipe is inserted into the sleeve 8 with the sleeve 9 until it stops. Mounting hooks 4 with springs mounted on the ears 3 of the clamp 2, diverge. The pipe freely enters the coupling, and when fully assembled, the end bends of the fasteners-hooks 4 fall into the recess 10, that is, the pipe 1 is reliably fixed to the couplings 8.

After assembly, water is supplied to the pipeline. The pipes are securely connected and the clamps 2 do not move at the working pressure of the water, since the clamps are securely fixed to the pipes with nuts 5 and bolts 6 on the ears 7.

The efficiency of using a collapsible pipeline is determined by the following advantages. Pipes have a simple design of the connecting nodes, which simplifies assembly during production and operation, since removable clamps are used. The use of removable clamps allows their repair, replacement or installation on pipes of different lengths by farmers or other customers.
