Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a rotary water sprinkler which exposes a water spout nozzle to the ground by water pressure to sprinkle water, and has an improved installation and assembly work. .

[Conventional technology]

Conventionally, the following buried type occupies most of this type of sprinkler.

For example, as shown in FIG. 3, a box (2) for accommodating a rotary water sprinkler (1), which is the main body of the device, is provided with a foundation (3) at a depth such that at least its upper surface is constantly exposed on the ground. It is placed on the top and the lower part of the box is buried in the ground, and the water supply port (4) formed at the lower end of the sprinkler (1) is provided with a water supply pipe (5) buried deeper in the ground. The connection is made by bending using (6).

The water pressure in the water supply pipe (5) causes the water sprinkler (1).
It pushes up the piston tube (7) inside the lower storage part (10) and hops up the upper nozzle part (8) with the upper lid to expose it to the ground, and at the same time, the nozzle part (8) sprinkles water while rotating. is there.

[Problems to be solved by the device]

When installing the above general rotary sprinkler at a predetermined place, the sprinkler (1), box (2), etc. that are assembled together after factory adjustment must be disassembled once at the installation site. I have to. This is because it is difficult to align the buried water supply pipe (5) with the water supply port (4) provided at the lower end of the sprinkler (1) when the entire device is assembled.

Also, in many sprinklers, the water inlet is at the lower end,
For example, PT11 / 2 is screwed in, so it is very difficult to level out. Furthermore, in the work at the factory site, detailed attention is often not paid to such disassembly, assembly and alignment of the sprinkler.

As a result, when operating the sprinkler installed in such a state, its performance may be greatly affected,
In addition, it may not hop up depending on the mounting position.

The troublesomeness of disassembling and then reassembling the water sprinkler assembled as described above and then reassembling it and the unfamiliar assembling work for the workers at the factory site imposes a heavy burden on the workers. ing.

The above-mentioned conventional problems are listed below.

 Installation work on site is extremely difficult.

When connecting with a buried pipe, it is impossible unless the sprinkler is disassembled.

 Extra work is added to workers on the factory floor.

By disassembling the set and assembled product on site, the product quality becomes unstable and varies, and the work of reworking will occur later.

Since the device body and the water supply pipe are leveled with screws, it is difficult to match the high and low standards.

Problems such as hop-up not occurring at the time of completion of installation at the site and trial run of water discharge, conversely not lowering, and nozzle not rotating occur, which necessitates various reworking.

[Means for Solving the Problems]

The present invention has developed a sprinkler system that solves these problems as a result of studies in view of the above problems.

That is, the present invention is a box (2) containing the sprinkler body.
Of at least the lower part of the box is buried in the ground, and the water supply port (4) at the lower part of the device body and the underground water supply pipe (5) are connected to each other. And a flange (9) is provided at the tip thereof to be fixed to the flange at the tip of the underground buried pipe. 2) It is more effective to extend to the outside of the side surface and provide the flange (9) at the tip thereof.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

<Embodiment 1> The water sprinkler of the present invention shown in FIG. 1 has a water supply port (4) on the side surface of a storage part (10) of a piston pipe (7) which constitutes a lower part of a water sprinkler (1) in a box. Is provided, the auxiliary pipe (11) screwed into the water supply port (4) is pulled out from the side surface of the box (2) to the outside, and the flange (9) is attached to the tip thereof.

In order to install such a sprinkler device in the ground, an underground foundation (3) is provided at the installation site, and the tip of the buried water supply pipe (5) is opened in the vicinity thereof, and the flange of the flange (9 ') is opened there. ) Is provided. Then, the box (2) is placed on the foundation (3) with the water sprinkler (1) still installed inside, and the flanges (9) and (9 ') are screwed together to be connected. The installation work is completed by filling the bottom of the box with soil.

The above-mentioned device of the present invention can be installed on site without being disassembled again after fixing the sprinkler (1) and auxiliary pipe (11) in the box with bolts and U bolts (12) in a factory or the like. Since it becomes possible, there are various advantages as described later. Further, according to the water sprinkler of FIG. 1, the burial depth of the burial water supply pipe (5) is remarkably shallower than the conventional one, and burial work of the water supply pipe (5) is also easy.

<Embodiment 2> The one shown in FIG. 2 uses an existing sprinkler, and an auxiliary box (1) is further attached to the lower end of the box (2) at a factory or the like in advance.
3) is attached to increase the height of the entire box, and the auxiliary pipe (11) attached to the water supply port (4) in this auxiliary box (13) is bent at a right angle with the elbow (6), and further U
The auxiliary box (13) is fixed to the auxiliary box (13) with bolts (12) and pulled out from the side surface of the auxiliary box (13), and a flange (9) is attached to the tip thereof.

To install such a sprinkler, a flange (9 ') is attached to the tip of the buried water supply pipe (5) as in the first embodiment, and the inside of the box (2) and the auxiliary box (13) is installed. Place the box on the foundation (3) in the ground with the sprinkler (1) and the auxiliary pipe (11) fixed, and screw the flanges (9) and (9 ') together. do it.

[Effect of device]

As described above, in the present invention, the water supply port of the sprinkler is pulled out to the outside and the flange is attached, so that the present invention has the following features.

Since the mounting flange is provided in advance, it is not necessary to disassemble the product at the time of installation work unlike the conventional case.

Therefore, it is not necessary to disassemble and assemble the equipment at the factory site.

 Installation work is very easy to do.

Because of the flange, it is easy to position the buried water pipe at the reference level.

Since no adjustments such as disassembling or assembling the product are performed on-site, the adjusted quality is stable at the time of factory shipment.

Since there is no disassembly or reassembly of the device, there is no change in basic performance such as vertical movement or rotation of the nozzle part, and inspection and adjustment of the device during trial run become easy.

Since the construction conditions are better than before, the number of on-site work steps is reduced.
