Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a road snow removal device that removes snow on a road by sprinkling groundwater onto the road surface.

[Problems to be solved by conventional technology and invention]

Road snow removal equipment has a groove carved in the center of the road.
There are two methods: a single piping system, in which a main water pipe is installed at the bottom of the trench, and a sprinkler pipe or nozzle tube is installed directly on this main water pipe; There is a double piping system in which water sprinkler pipes of a predetermined length are arranged on the left and right sides of approximately equal length, and water spray nozzles are provided in the water spray pipes.

With the single piping system, piping is simple and piping costs are reduced, but since the water fountain pressure differs between locations near and far from the pump, it is necessary to use a water spray nozzle with an adjustment valve that can accurately adjust the water flow rate. However, the disadvantage is that the cost of the water nozzle is high.

The double piping system is a water spray nozzle that does not require adjusting the water flow rate (it is okay to have a simple flow rate adjustment mechanism to some extent, but it must be a water spray nozzle with a control valve that can accurately and variably adjust the water flow rate). ) can be used, which reduces the cost of the water spray nozzle, but on the other hand, the cost of piping increases.In particular, the valve mechanism for regulating the flow rate is separated parallel to the main water pipe 1 as shown in Figure 4. The branch pipes 30 must be installed in parallel, and the communication pipes 31 and 32 of the branch pipes 30 must also be installed in parallel, which means that the width of the carved grooves must be increased, which reduces piping costs. Not only does it become even taller, but it also has drawbacks such as the position of the water spray nozzle being off the center line.

[Means to solve the problem]

The present invention solves the disadvantages of the double piping system and utilizes the advantages of the double piping system to provide a double piping type road snow removal device that is more practical than the single piping system.Please refer to the attached drawings. The detailed configuration is as follows.

Branch pipes 2 are erected at predetermined intervals from the main water pipe 1, and a water sprinkler pipe 3 of a predetermined length is connected to the tip of the branch pipe 2 at the middle part, and the water sprinkler pipe 3 sprinkles water on the road surface a. In a double-piped snow extinguishing device equipped with a water spray nozzle 4, a branch pipe 2 is vertically installed directly above the main water pipe 1, and a valve shaft 5 is arranged in the axial direction of the branch pipe 2. Valve operation chamber 6 arranged on the water sprinkler pipe 3
The valve shaft 5 inside the valve operation chamber 6
is provided so as to be rotatable from above the road surface a, a valve device 7 which is opened and closed by the rotation of this valve shaft 5 is provided in the branch pipe 2, and water sprinkling nozzles 4 are arranged on the water sprinkling pipe 3 at appropriate intervals. It is characterized by:

In addition, the main water pipe 1 is connected with a T-shaped joint 8, a T-shaped valve pipe 9 is connected to the rising pipe part 8a of the T-shaped joint 8 corresponding to the branch pipe 2, and a valve device is installed in this T-shaped valve pipe 9. 7 is provided, and water sprinkling pipes 3 of approximately equal length are connected to the left and right sides of a T-shaped valve pipe 9 with water sprinkling nozzles 4 attached at appropriate intervals.

[Effect]

When the pump is started to pump up groundwater and the water is passed through the water main pipe 1, and the valve shaft 5 is rotated from above the road surface a to open the valve device 7, the water is passed into the water sprinkling pipe 3, and from the water nozzle 4 to the road surface. Water is sprinkled on a.

The amount of water sprinkled is adjusted by the degree of opening and closing of the valve device 7.

〔Example〕

The drawing shows a preferred embodiment of the present invention, in which branch pipes 2 are installed upright at a predetermined interval from a main water pipe 1, and a water sprinkler pipe 3 of a predetermined length is attached to the tip of the branch pipe 2. In a double piping type snow extinguishing device in which the sprinkler pipe 3 is connected at the middle and has a sprinkler nozzle 4 for sprinkling water on the road surface a, the branch pipe 2 is vertically installed directly above the main water pipe 1. , a valve operation chamber 6 in which a valve shaft 5 arranged in the axial direction of the branch pipe 2 is arranged on the water sprinkler pipe 3;
The valve shaft 5 inside the valve operation chamber 6
is provided so as to be rotatable from above the road surface a, a valve device 7 which is opened and closed by the rotation of this valve shaft 5 is provided in the branch pipe 2, and water sprinkling nozzles 4 are arranged on the water sprinkling pipe 3 at appropriate intervals. .

The illustrated branch pipe 2 is formed by connecting the water main pipe 1 with a T-shaped joint 8, connecting the T-shaped valve pipe 9 to the rising pipe portion 8a of the T-shaped joint 8 corresponding to the branch pipe 2, and connecting the T-shaped valve pipe 9 with the T-shaped joint 8. A valve device 7 is provided in the valve pipe 9, and water spray pipes 3 of approximately equal length are connected to the left and right sides of the T-shaped valve pipe 9, with water spray nozzles 4 attached at appropriate intervals.

The head of the water spray nozzle 4 faces the road surface a through the riser pipe 4', and the head of the valve operating chamber 6 faces the road surface a through the peripheral wall.

The valve operation chamber 6 may be provided with a box as shown in the figure, or may be provided with a chamber space on the road itself without providing a box.In short, a handle or the like can be inserted from above the road surface a to operate the valve. It is sufficient if the configuration is such that the shaft 5 can rotate.

In the valve device 7 shown in the drawings, a tapered valve surface 11 is formed on the upper peripheral edge of a valve seat 10 screwed onto the lower end of a valve shaft 5, and a tapered surface 12 with which this tapered valve surface 11 comes into contact is formed at the intersection of a T-shaped valve pipe 9. A guide recessed groove 15 is vertically formed on the lower surface of the valve port 13 which is open at the bottom and engages with a guide protrusion 14 vertically provided on the inner circumferential wall of the vertical pipe 9a of the T-shaped valve pipe 9 on the outer periphery of the valve seat 10. , shows a case in which the valve seat 10, which is held in a non-rotating state by the guide protrusion 14 when the valve shaft 5 is rotated, is raised and lowered by a screw mechanism to open and close the valve port 13.

The ring 16 shown in FIG. 2 is a stopper ring that prevents the valve seat 10 from lowering from a predetermined position. It is attached.

〔Effect of the invention〕

As described above, the present invention has a branch pipe vertically installed directly above a main water pipe, and a valve shaft arranged in the axial direction of the branch pipe protrudes into a valve operation chamber arranged on a water sprinkler pipe. The valve shaft in the valve operation chamber is installed so that it can be rotated from above the road surface, a valve device that opens and closes by the rotation of the valve shaft is installed in the branch pipe, and water sprinkling nozzles are arranged at appropriate intervals in the water sprinkling pipe. Because of this, the valve shaft in the valve operation chamber can be easily rotated by a worker on the road using an appropriate tool, and the valve device that adjusts the water flow rate by rotating the valve shaft is Since each branch pipe is installed directly inside the branch pipe, and there is no need to adopt a branch piping system that is installed alongside the conventional sprinkler pipe as shown in Figure 4, the piping cost can be reduced accordingly. The width of the groove provided can be narrowed, and an inexpensive water spray nozzle without a flow rate regulating valve mechanism can be used, resulting in an extremely economical road snow removal device.
