Description

[Detailed description of the invention] [Industrial application field of the invention] This invention relates to a snow melting device that is buried in places where the pavement cannot be thick, such as the roof of a building or a parking lot.

[Technology related to the invention and its problems]

Generally, snow melting equipment is buried in roads with thick pavement layers by connecting the water pipe formed at the bottom of the snow melting nozzle to a single or double pipe buried in the axial direction of the road via a vertical connecting pipe. However, this pipe was to be connected to a groundwater pump. In this case, on roads with a thick pavement layer, there is sufficient space between the water pipes in the vertical direction, but in places with a shallow pavement layer, such as on the roof of a building or in a parking lot, the pipes are connected to the vertical nozzle water pipes. There was a problem that it could not be placed below the .

[Purpose of invention]

The purpose of this invention is to provide a snow melting device that can efficiently bury a snow melting nozzle and a water supply pipe for conveying water for snow melting in a shallow pavement layer such as on the roof of a building.

[Structure of the idea]

In order to achieve the above object, this invention provides a water pipe at the bottom of the nozzle body, and a water storage pipe having a hollow part communicating with the water supply hole of the water pipe through a partition at the top, and the head of this water storage pipe. In a snow melting device for a shallow pavement layer, a snow melting nozzle having a water fountain hole is buried in a shallow pavement surface, the upper surface of the head having the water fountain hole is exposed, and a water supply pipe connected to the water pipe is buried. , closing the lower end of the water pipe and forming a water hole on the side of the water pipe, burying the water supply pipe in a side location on the side of the water pipe, and inserting one end of the connecting pipe into the water hole. The other end is connected in communication with the water supply pipe.

[Example of idea]

Reference numeral 1 denotes a snow melting nozzle, and a water pipe 3 is provided at the bottom of the nozzle body 2 of the snow melting nozzle 1 with the lower end closed, and a water storage pipe 5 is connected to the upper part of the water pipe 3 via a partition wall 4. A head 7 with inclined water fountain holes 6 provided radially is connected to the water storage pipe 5 to form a cavity 9 communicating with the water supply hole 8 inside the water pipe 3, and the center of the head 7 is A female screw portion 10 is bored in the
A top pipe 11 is screwed into this female threaded portion 10, a female screw hole 12 is bored in the center of this top tube 11, and a water volume adjustment rod 14 having a driver groove 13 on the upper surface is screwed into this female screw hole 12. This water volume adjustment rod 14
The lower part of the partition wall 4 is fitted into the communication hole 15 of the partition wall 4 and has a cut groove 16 vertically provided therein.

Then, the snow melting nozzle 1 is buried in the pavement layer A with the fountain hole 6 protruding from the pavement surface A.

Reference numeral 17 denotes a water hole bored in the side of the water pipe 3 of the snow melting nozzle 1, and the water hole 17 is formed horizontally or outwardly from the water hole 8 and slightly diagonally downward. At the same time, a female screw portion 18 is formed around the periphery of the water passage hole 17 .

Reference numeral 19 denotes a connecting pipe having a male threaded portion 20 at one end screwed into the female threaded portion 18 of the water passage hole 17;
It is fitted and connected to a connecting pipe 22 that is connected and fixed to the side of a water supply pipe 21 buried in a lateral location on the side of the water passage hole 17 . The water supply pipe 21 is connected to a rising pipe or a water pipe (none of which is shown) connected to a well pump.

Then, the water press-filled into the connecting pipe 19 from the water supply pipe 21 reaches the water supply hole 8, passes through the communication hole 15 through the cut groove 16 at the bottom of the water volume adjustment rod 14, is injected into the cavity 9, and is injected into the cavity 9. After the water is filled, water is sprayed from the water fountain hole 6. Also, to adjust the amount of watering,
By applying a driver (not shown) to the driver groove 13 and rotating the water amount adjustment rod 14, the amount of overlap between the communication hole 15 and the cut groove 16 is varied, and the amount of water to be sprayed is adjusted.

The height of the water supply pipe 21 is the same as the water passage hole 17 of the snow melting nozzle 1.
Although it is installed horizontally or at a slightly downward angle, depending on the diameter of the water supply pipe 21, if it is installed at a position higher than horizontal, the distance between it and the pavement surface becomes shallow, causing cracks and depressions on the pavement surface. It's inappropriate.

[Effect of idea]

In this invention, a water pipe is provided at the bottom of the nozzle body, a water storage pipe is provided at the upper part of the nozzle body, and the water storage pipe has a cavity that communicates with the water supply hole of the water pipe via a partition wall, and a water fountain hole is provided at the head of the water storage pipe. In the snow melting device for a shallow pavement layer, the snow melting nozzle is buried in a shallow pavement surface, the upper surface of the head having the water fountain hole is exposed, and a water supply pipe connected to the water pipe is buried, the lower end of the water pipe. a water passage pipe is formed on the side of the water passage pipe, the water supply pipe is buried in a side location on the side of the water passage hole, one end of the connecting pipe is connected to the water passage hole, and the other end is connected to the water passage hole. Since it is connected to the water supply pipe, it is possible to bury the snow melting device in a shallow pavement layer such as the roof of a building, and it is also possible to bury the snow melting device in a shallow layer of pavement, such as on the roof of a building.Moreover, it is possible to bury the snow melting device in a shallow layer of pavement, such as on the roof of a building. A water sprinkling effect can be obtained, which has a great practical effect.
