Description

[Detailed Description of the Invention] This invention relates to a riser pipe for a water sprinkler device that is bent when not in use so as not to interfere with other operations other than watering operations.

For example, for irrigation of tea plantations or for waterproofing against frost.
A riser pipe is installed on a water pipe installed underground or above ground.
A water sprinkling device with a water sprinkling nozzle attached to the riser pipe is used, but since the water nozzle is placed above the tea, the riser pipe becomes a hindrance to tea picking work or other work.

In view of the above-mentioned points, this invention is designed so that various operations can be easily performed by bending the riser pipe of the water sprinkler except when water sprinkling is required.

The gist of this invention is to provide a riser pipe for a sprinkler system in which two pipes are connected by a bendable joint pipe, and a sheath pipe longer than the joint pipe is fitted into the joint part so as to be movable in the pipe axial direction. Exists.

Next, the standpipe for the sprinkler system of this invention will be explained with reference to an embodiment of the drawing. 6 1 is a water pipe installed underground, 2 is a water pipe branched from the water pipe 1 and protruded above the ground. The first riser 3 is a second riser connected to the first riser 2 .

The second riser 3 is connected to the first riser 2 by a bendable joint pipe 4 .

A sheath tube 5 is longer than the joint tube 4, and is fitted into the connecting portion of the riser tubes 2 and 3 so as to be movable in the axial direction.

21 is a projection for locking the sheath tube 5.

The two riser tubes 2, 3 as well as the sheath tube 5 are made, for example, from hard vinyl chloride resin, and the joint tube 4 is made, for example, from rubber or soft synthetic resin.

6 is a water nozzle, which is attached to the second riser pipe 3 via a nipple T.

When the sheath pipe 5 is fitted into the connecting portion of the first riser pipe 2 and the second riser pipe 3 in a state where it is locked to the protrusion 21, both ends of the sheath pipe 5 are connected to the first riser pipe 5, respectively. As a result of being fitted over the riser pipe 2 and the second riser pipe 3, the second riser pipe 3 is placed in an upright state, and is placed in a state where it can be used as an enemy (see Fig. 1).

When the housing and sheath pipe 5 are moved above the joint pipe 4, the joint pipe 4 becomes bendable and the second riser pipe 3 is turned sideways (see Fig. 2).

As described above, in the standpipe for a sprinkler device of this invention, two pipes are connected by a bendable joint pipe, and a sheath pipe longer than the joint pipe is fitted into the joint so as to be movable in the pipe axial direction. Therefore, when watering, the two pipes are kept upright by the sheath pipe, and when water sprinkling is not required, the riser pipe can be easily bent by moving the sheath pipe and shifting it from the connection part.

Therefore, the standpipe does not become an obstacle to various operations other than watering operations.
