Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a water spray nozzle for snow melting that can easily change the water spraying state in any way and easily eliminate clogging of the upper nozzle hole. .

[Conventional technology]

In snow-covered regions, water nozzles are buried in the ground to remove snow from roads and parking lots, and these nozzles spray groundwater or river water around the area to remove snow.

This water spray nozzle has narrow nozzle holes extending radially through it, but these nozzle holes tend to become clogged with pebbles and must be unclogged from time to time.

This process involves inserting a thin wire-like rod into the clogged nozzle hole to pull out the pebbles and ejecting them with the power of the water jet, but the nozzle hole is likely to get clogged again at this time, so it is necessary to reduce the flow rate. The drawback was that it was a cumbersome task to remove the valve lever to adjust it, and to throw away any pebbles that had been knocked down.

Furthermore, in order to change the water sprinkling state, the water sprinkling nozzle body itself must be replaced, and the replacement work is also very troublesome.

[Problem to be solved by the invention]

The present invention provides a convenient water spray nozzle for snow melting that allows the water spray holes to be easily unclogged and the water spray conditions to be changed very easily.

[Means to solve the problem]

The configuration will be described in detail with reference to the accompanying drawings as follows.

A water sprinkling guide plate support surface 3 is provided on the top of the water sprinkling nozzle body 1.
A water sprinkling guide board 2 is placed and tightly fixed on this water nozzle board support surface 3, and a bulging strip is formed in the radial direction on the water sprinkling guide board 2 to form a water sprinkling passage 4. The lower surface of the mounting part 2' of the watering guide board 2 that communicates with the passage 4 and the locking step part 8 that serves as the mounting part supporting surface.
A water passage gap 4' is provided in communication with the rectification chamber 14 of the water sprinkling nozzle body 1, and various types of water sprinkling guide boards 2 with different widths and pitches of the water sprinkling passages 4 are attached to the water sprinkling guide board mounting part a. This relates to a water sprinkler nozzle for snow melting, characterized in that the water spray nozzle is fixed in a replaceable manner.

In addition, the water sprinkling for snow removal is characterized in that the mounting portion 2' of the water sprinkling guide board 2 is fixed by the collar portion 7 provided on the head of the valve barrel 5 that adjusts the amount of water sprayed and fixed to the water nozzle body 1. This relates to nozzles.

[Effect]

For example, when the product of the present invention is fitted into the riser pipe of a water pipe buried in the road surface and groundwater is sent, the groundwater sent from the riser pipe passes through the sprinkler nozzle body 1 and connects to the water sprinkling guide plate support surface 3 and the water sprinkling guide. Water is sprinkled onto the road surface from a watering passageway 4 formed with the board 2.

If you want to change the watering state, replace the watering guide board 2 with a watering passageway 4 of a different width, pitch, or attached state.

〔Example〕

As shown in FIGS. 1, 2, and 3, a tapered surface with an inclined outer side that supports a water sprinkling guide board 2 and is higher on the outside is formed on the upper part of the water sprinkling nozzle body 1, and this tapered surface is used as a water sprinkling guide board supporting surface 3.

The structure of the water sprinkling nozzle is that a bolt-shaped screw rod 6 is inserted into the center of a normal water sprinkling nozzle body 1, and a locking step 8 to which a flange 7 on the head of the inserted screw rod is locked is attached to the locking step 8 of the water sprinkling nozzle body 1. Since it is formed at the upper center, this structure can be used as it is, and the supporting surface 3 of the water guide plate
A water sprinkling guide board 2 whose entire circumference is pressed into a cross-sectional shape of peaks and troughs and radially bulging stripes are arranged on the back surface is placed thereon.
A water sprinkling guide is formed by screwing the valve cylinder 5, which has a flange 7 formed on the upper part of the threaded rod 6, into a female threaded hole 13 provided in a partition wall 12 in the water sprinkling nozzle body 1 with a rubber gasket 9 interposed therebetween. The figure shows a case where a water sprinkling passage 4 is formed by fixing the board 2 to a water sprinkling guide board support surface 3.

Figures 4, 5, 6, and 7 show other examples of the watering guide board 2. Figure 4 shows the case where there are four watering passages 4, and Figure 5 shows the case where there are four watering passages 4 with wide grooves. Figure 6 shows the case where six watering passages 4 are arranged in parallel in one place so as to sprinkle water in a fan shape, and Figure 7 shows the case where one watering passage 4 sprinkles water in a fan shape. It shows.

In this way, by replacing and using the watering guide board 2 having the watering passages 4 according to snow-melting conditions, various types of watering can be obtained.

Reference numeral 10 is a water sprinkling amount control valve that adjusts the amount of water being sprinkled;
11 is a protrusion that forms a water passage gap.

〔Effect of the invention〕

Since the present invention is configured as described above, the water sprinkling passage is not of the conventional type in which nozzle holes are drilled in the water sprinkling nozzle body itself, but by the bulging strips of the water sprinkling guide plate placed on the supporting surface of the water sprinkling guide plate. Because it is a type in which a water sprinkling channel is formed, it does not get clogged like in conventional ones, and even if it does become clogged, it can be easily unclogged. By simply lifting it up a little, all of the debris that causes clogging, such as sand and pebbles, can be sprayed and removed from the entire surface of the watering guide support surface, making it easy to clear clogging of the watering passageway and at the same time replace the watering guide board to eliminate snow. By selecting a water sprinkling guide board with water sprinkling passages that match the conditions, it is possible to easily ensure an appropriate water sprinkling condition at all times, resulting in a highly practical snow-melting water sprinkling nozzle.

Moreover, the watering guide board is designed to be easy to install and remove, and if you prepare various watering guide boards as shown in Figures 4, 5, 6, and 7, you can perform various types of watering, such as four-way watering, six-sided watering, one-sided watering, fan-shaped watering, etc. The desired watering conditions can be achieved by simply replacing the watering guide board, and there is no need to dig up the buried watering nozzle body and replace it with another watering nozzle body, which is very convenient. It has excellent features such as being used as a water spray nozzle for snow removal.
