Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a snow-melting water hose used to melt snow on roads.

(Prior art) Traditionally, in snowy areas, metal pipes with many water holes are buried in the road surface, and when it snows, snow melting water is sprinkled from the metal pipes to prevent snow accumulation and ice on the road surface. Water sprinkler systems designed to prevent water damage are commonly used.

(Problem that the invention aims to solve) However, the above-mentioned sprinkler equipment requires metal pipes to be buried in the road surface, which costs a huge amount of money, so it is only installed on main roads. is the current situation.

Therefore, on roads etc. that do not have this type of watering equipment,
Snow removal is carried out by snowplows or by hand.
Particularly in places where snowplows cannot be used, such as narrow roads or passageways inside private residences, all snow removal work must be done manually, and this work requires a large amount of labor.

This idea was created in consideration of the above points, and it can be easily installed in a place where snow melting is required, connected to a water hose as needed, and can be rolled up and stored in a small package when not in use. The purpose of the present invention is to provide a relatively inexpensive watering hose that is convenient to handle, has a high snow melting effect, and is relatively inexpensive.

(Means for solving the problem) This idea has a mountain-shaped cross section with a central part that swells up against the ground surface, both sides of which draw a gentle curve, and end at both edges, providing a passageway inside the body. Summary of a watering hose for snow melting, which is composed of a hose body made of a flexible material and a watering nozzle with watering holes, in which a plurality of the watering nozzles are fixed at appropriate intervals by passing through a water passage from both sides of the hose body. That is.

(Function) The watering hose of this invention can be used by simply connecting one end of the hose to a water supply hose or immersing it in running water, and allowing water to constantly flow through the watering hose during snowfall. It has the effect of melting the snow that is spread onto the road through the holes and preventing snow from accumulating on the road.

In addition, the water sprinkling hose of the embodiment has a water sprinkling nozzle configured with a screw, and the water sprinkling hole is bored with the water sprinkling hole being inclined with respect to the central axis of the screw. By periodically rotating each water spray nozzle and adjusting the direction of the water spray holes, the water spray position can be changed as appropriate, making it possible to melt snow over a wide range.

(Example) Hereinafter, an example of this invention will be described based on the drawings.

Fig. 1 is a partial perspective view of an embodiment of a watering hose for snow melting, Fig. 2 is a plan view of the same, Fig. 3 is a cross-sectional view taken along the - line in Fig. 2, and Fig. 4 is a partial perspective view of the water hose for snow melting. A vertical cross-sectional view with some parts omitted is shown.

In Figures 1 to 3, 1 is the hose body;
The hose main body 1 has a central part that swells with respect to the ground surface, and has a substantially chevron-shaped cross section with both sides drawing a gentle curve and ending at both edges, and a water passage 2 is provided in the hose main body 1. Although the material of the hose body 1 is not particularly limited, it is usually formed by extrusion molding from a flexible material such as soft synthetic resin or rubber so that it can be wound onto a hose reel or the like.

Reference numeral 3 denotes a water spray nozzle, and this nozzle 3 has a structure in which a water spray hole 3b penetrating through the axial center of a positive or negative countersunk screw 3a is formed. In this embodiment, the water sprinkling hole 3b is formed at an angle with respect to the central axis of the countersunk screw 3a so that the direction of water sprinkling can be changed by rotating the nozzle 3. Also, water spray nozzle 3
is not limited to the above-mentioned countersunk screw 3a as long as it is fixed to the hose main body 1, and the tip facing the water passageway 2 may be in the shape of a hook. The watering hose for snow melting of this invention is provided with appropriate intervals (for example,
500 mm), a plurality of pilot holes leading to the water passageway 2 are drilled in advance, and a water spray nozzle 3 is inserted into each pilot hole from both sides of the hose body 1 to the water passageway 2 and fixed therein.
Preferably, it is screwed on, and one end of the water sprinkling hole of the water sprinkling nozzle 3 is configured to face the passageway 2 .

Reference numeral 4 denotes a plug body, and this plug body 4 is fitted onto one end of the water passageway 2 of the hose body 1 to close the water passageway 2. 5
is a connecting fitting, and this connecting fitting 5 is fitted into the other end of the water passage 2 and is used, for example, to connect the water hose 6 and the hose body 1.

Next, how to use the watering hose of the above embodiment will be explained.

Usually, a snow-melting water hose that is stored rolled up on a reel or the like is rolled back up and installed on the road surface where snow accumulation is to be prevented, for example along the center part. As shown in FIG. 4, when the snow-melting watering hose is connected to the water supply hose 6, the socket 7 is opened to allow tap water to flow into the hose body 1. In this state, water is blown out from each water sprinkling nozzle 3, so the direction of the water sprinkling hole is changed by adjusting the rotation of the nozzle 3 as appropriate using a screwdriver (not shown), thereby changing the water sprinkling direction. In this way, by constantly sprinkling water during snowfall, snow that has accumulated on the road surface or snow that is about to accumulate is melted and snow accumulation is prevented.

In addition, if the water spray nozzle 3 is periodically rotated and the water spray position is changed, snow accumulation can be prevented over a relatively wide range.

(Effects) As mentioned above, the snow-melting watering hose of this invention has a substantially mountain-shaped cross section with a raised central part and gentle curves on both sides, making it suitable for use in automobiles and other vehicles. It is safe because it does not impede the passage of vehicles such as motorcycles, and there is little risk of being hit by pedestrians.

In addition, since the snow melting water hose is made of a flexible material such as soft synthetic resin or rubber, it can be stored by winding it up on a hose reel when not in use, and there is no storage space. It is small and convenient to handle.

Furthermore, the water sprinkling holes are not formed by directly drilling into the hose body, but instead are formed in the water nozzle and screwed into the hose body, so there is no chance of clogging with pebbles, and the water flows smoothly over a long period of time. becomes stable. Moreover, by providing the water sprinkling holes at an angle with respect to the central axis of the screw as in the embodiment, the water sprinkling direction can be changed and a wide range of snow can be melted.
