Description

[Detailed description of the invention] This invention relates to a water spray nozzle for road snow removal, which sprays groundwater onto the road surface to erase snow.

Conventional water spray nozzles of this kind include those in which the water pipe and the nozzle head are integrally formed, as in Japanese Utility Model Application No. 52-88427 and Japanese Utility Model Application Publication No. 52-83524, or the one in which the water flow pipe and the nozzle head are integrally formed, as in Japanese Utility Model Application Publication No. 52-88427 and Japanese Utility Model Application Publication No. 52-83524.
As shown in Publication No. 26738 and Publication No. 157239 of 1983, the structure was such that a cleaning lid was removably attached to the nozzle head that was integrally formed with the water pipe. In order to do this, the road must be demolished to raise the height of the nozzle, which requires a lot of effort and time, and has been a major challenge for the industry.

This invention was made in view of the above-mentioned circumstances, and its purpose is to make it extremely easy to raise the height of the water spray nozzle so that there is no problem when paving roads.

Next, the structure and operation of this invention will be explained with reference to the drawings.

Standing pipes 2 are set up in places of a water pipe 1 buried in a road, and a water pipe 4 is externally fitted onto the upper part of the rising pipe 2 via an O-ring packing 3.

A water storage pipe 6 is connected to the upper part of the water pipe 4 via a partition wall 5 to form the embedded body a.

The circumferential side surface of this embedded body a is made into a tapered surface 7 whose diameter becomes smaller toward the bottom.

The water storage pipe 6 of the embedded main body a is provided with a cavity 9 that communicates with the water supply hole 8 of the water pipe 4, and a stepped part 10 is provided at the upper periphery of the cavity 9.

A disk 12 having a circumferential side surface 11 continuous with the tapered surface 7 of the implant body a is provided, a circular hole 13 having the same diameter as the cavity 9 is bored in the center of the disk 12, and the lower peripheral edge of the circular hole 13 is provided. A flange 14 that fits into the stepped portion 10 is vertically provided in the circular hole 13.
A step portion 15 is provided on the upper periphery of the raised member b to form a raised member b.

The thickness of each raising member b may be uniform or may vary as appropriate.

The flange 14 of the raising member b is attached to the stepped portion 10 of the embedded main body a.
At the same time, the flange 14 of another raising member b is fitted to the stepped portion 15 of the raising member b, and one or more raising members b are fitted onto the embedded main body a.

A flange 16 vertically provided around the lower surface of the nozzle head is fitted to the stepped portion 10 of the raised member b, and the nozzle head C is fitted above the raised member b.

The circumferential side surface 25 of the nozzle head C is made into a tapered surface.

A pair of screws 17 are screwed into the embedding body a from the upper surface of the nozzle head C through the raising member b, and the raising member b and the nozzle head C are removably screwed into the embedding body a.

A hollow portion 9 is provided inside the flange 16 on the lower surface of the nozzle head C.
A water guide portion 18 communicating with the water guide portion 18 is provided, and water spray nozzle holes 19 communicating with the water guide portion 18 are provided at an angle on all sides of the upper surface of the nozzle head C.

A water amount adjustment knob 22 having a driver groove 20 at the upper end and a male screw portion 21 approximately in the upper half is screwed into the center of the nozzle head C.

A cylinder 23 is protruded from the upper end of the water supply hole 8, a cut groove 24 is formed in the cylinder 23, and a water amount adjustment knob 22 is placed facing the cylinder 23 to adjust the water amount.

However, when a water spray nozzle with a nozzle head C screwed onto the upper part of the embedded body a is attached to the riser pipe 2 without using the raising member b as shown in Fig. 3, it is difficult to newly pave. When the road surface becomes higher than the water nozzle, first remove the screw 17 as shown in FIG. .

Next, the raising member b is fitted onto the main body a with appropriate mathematics.

In this case, the thickness of the raising member b is made equal to the height increased by the paving.

In addition, the flange 16 of the raising member b is fitted into the stepped portion 10 of the embedded main body a, and is placed on the embedded main body a,
Its circumferential surface becomes a connected tapered surface.

Next, the flange 16 of the nozzle head C is fitted into the stepped portion 10 of the raising member b, and the embedded body a, the raising member b, and the nozzle head C are screwed together with the screws 17.

In addition, the water amount can be adjusted by screwing the water amount adjustment knob 23.

After elevating the water spray nozzle in this way, the fifth height can be adjusted relatively finely, and in addition, the elevating member b is in the form of a relatively thin plate with approximately the same diameter as the embedded member a; One or more raising members b are fitted to the embedded body a in which a water storage pipe 6 is connected via the assembly and partition wall 5, and a nozzle head C having a water volume adjustment knob 22 in the center is placed on the raising member b. The feature is that the nozzle head C and the raised member b are screwed onto the embedded body a, and water can be sprayed by simply removing the nozzle head C from the embedded body a and intervening the raised member b as appropriate. Since it is possible to raise the height of the nozzle, the complicated work of replacing water nozzles when paving roads is eliminated, which greatly shortens the construction period and reduces construction costs, so the effect is great.

In addition, in the conventional Japanese Utility Model Publication No. 49-53527, the overlay socket has an annular shape as a whole between the nozzle cap and the nozzle body, or has a stepped portion on the upper inner wall and a threaded portion below the stepped portion, or On the other hand, since the structure has a stepped part on the lower part of the outside and the lower part is shaped like a screw, it is not possible to adjust the raised height, and there is also the trouble of first removing the nozzle cap when adjusting the pressure regulating valve. There is a drawback that the partial pressure regulating valve is located at the lower part and is difficult to adjust.
In Japanese Patent No. 42841, an upper nozzle for raising the height is attached, which is very uneconomical.

In addition, in Japanese Utility Model Application Publication No. 53-82529, a connecting member and a snow removal nozzle suitable for the connecting member must be attached, which is even more uneconomical.

Further, in Japanese Utility Model Application Publication No. 53-82531, a raising member having substantially the same shape and size as the embedding body is required, making it difficult to adjust the raised height and being uneconomical.

However, in this invention, in a nozzle that can be divided into upper and lower halves, consisting of an embedded body a and a nozzle head C having approximately the same diameter as the embedded body a, the nozzle is relatively thin and has a water passage hole 13 that has approximately the same diameter as the embedded body a. A flat raising member b is provided, and the flat raising member b is interposed between the embedded body a, which can be divided into two, and the nozzle head C over an appropriate number of the entire width, and the raised height is determined by the number of the raising members b. In addition, since the nozzle head C, an appropriate number of raising members b, and the embedded body a are tightened by vertical screws 17, the number of relatively thin raising members b to be installed can be reduced. By changing the height, the road surface is raised by paving to the same height as the nozzle head C, as shown in the elevation map.

This invention, as described above, is easy to adjust at the top of the water pipe 4, does not require replacing the nozzle head C or the embedded body a with new ones for raising the height, and is economical, and has a large effect. .
