Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a track watering device that is installed beside a railroad track or the like and sprays water onto the track to melt and remove accumulated snow.

[Conventional technology]

In a known track watering system, when the watering pressure is adjusted to increase or decrease the amount of water per unit time depending on the snowfall amount, the spraying angle is always constant, so the flying distance of the water changes and the watering area changes. The amount of water per unit area does not change much, just by making it wider or narrower. Therefore, it is impossible to obtain an efficient snow melting effect by actively adjusting the water spray pressure.

Also, known track water sprinklers do not allow for changes in water spray pressure. Therefore, if the water spraying pressure becomes lower than the planned value as an unexpected situation, the watering area will become smaller than planned.

[The problem that the idea attempts to solve]

The present invention was developed in consideration of the above points, and it prevents the watering area from changing when the watering pressure is actively adjusted according to the amount of snowfall, and also prevents the watering pressure from becoming lower than the planned value in unforeseen circumstances. To provide a track watering device in which the watering area does not change even when the area is watered.

[Means to solve the problem]

In order to achieve the above object, the track watering device of the present invention is a track watering device that is installed beside a track, sprays water on the track to melt and remove snow, and is connected to a water supply source. A water pipe is installed in a header pipe via a flexible tube so as to be freely tiltable, a sprinkler section is provided at the upper end of the water pipe to spray water at a predetermined watering angle, and a guide member is erected beside the water pipe. to determine the inclination of the water pipe in the water sprinkling direction, install a cylinder between the header pipe and the water pipe in the form of a link, connect the cylinder to the header pipe with a cylinder tube swingably; A piston is slidably inserted into the cylinder tube, one end of the cylinder rod is connected to the piston, and the other end of the cylinder rod is swingably connected to the water pipe,
The piston is elastically biased in the retraction direction of the cylinder rod by a spring, the header pipe and the cylinder tube are connected via a hose, water spray pressure is introduced into the cylinder tube, and the water spray pressure causes the piston to move toward the cylinder rod. The cylinder rod is extended in accordance with the water sprinkling pressure, the water pipe is tilted, and the water sprinkling angle is made smaller.

[Effect]

The track sprinkler system of the present invention sprays water, which is supplied from a water supply source to a sprinkler unit via a header pipe and a water pipe, onto a track. The water fed to the header pipe has a predetermined pressure (water spray pressure), and this water spray pressure is introduced into the cylinder. The cylinder expands and contracts in accordance with the water spray pressure, and in response to this expansion and contraction, the water pipe is tilted to change the water spray angle of the sprinkler section.

[Example] Next, an example of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, a water supply pipe 4 is vertically installed on a header pipe 2 connected to a water supply source (not shown) via a flexible tube 3, and a predetermined position is provided at the upper end of the water supply pipe 4. A sprinkler section 5 is attached that sprays water at a water spraying angle θ. The water pipe 4 is a flexible tube 3 that is deformed and tilted, and the water sprinkling angle θ is a predetermined elevation angle.

A pair of guide members 6 are erected on the header pipe 2 with the water pipe 4 in between, and arc-shaped guide holes 7 are formed near the upper ends of the guide members 6, respectively. A pair of engagement protrusions 8 protruding from the outer surface of the water pipe 4 at 180-degree symmetrical positions are slidably engaged with the guide hole 7 along an arc, so that the water pipe 4 is tilted in the water sprinkling direction (first direction). (right direction in the figure) only.

A cylinder 9 is installed between the header pipe 2 and the water pipe 4.
are constructed in the form of links. The erection location is on the opposite side of the watering direction.

That is, a cylinder tube 10 is connected to the header pipe 2 so as to be swingable about a shaft 11,
A piston 12 is slidably inserted into the cylinder tube 10. One end of a cylinder rod 13 is connected to this piston 12.
The other end of 3 is connected to the water pipe 4 so as to be swingable about a shaft 14 . The piston 12 is elastically biased by a spring 15 in a direction in which the cylinder rod 13 retracts. Further, the header pipe 2 and the cylinder tube 10 are connected via a curled hose 16 so that water spray pressure is introduced into the cylinder tube 10. When water spray pressure is introduced into the cylinder tube 10, the piston 1
2 is pressed in the direction of extension of the cylinder rod 13,
The cylinder rod 13 expands according to the water spray pressure,
The water pipe 4 is tilted in accordance with the extension, and the water sprinkling angle θ becomes smaller in accordance with the tilt. The relationship between the water spraying pressure and the watering angle θ is set in advance so that the flying distance of water is always constant. 17 is a pipe connection port, and 18 is a pressure gauge for measuring water spray pressure.

As shown in FIG. 3, a plurality of track water sprinklers 1 having the above configuration are installed on both sides of tracks A and B, and water is supplied from a water source to a sprinkler section 5 via a header pipe 2 and a water pipe 4. Water (cold water or hot water) is sprinkled on tracks A and B to melt and remove snow on tracks A and B. The water supplied to the header pipe 2 is supplied with a predetermined spray pressure by a pump or the like, and a portion of the water is introduced into the cylinder tube 10 via the hose 16, and the cylinder rod 13 is pumped according to the water spray pressure. The water pipe 4 is extended, the water pipe 4 is tilted, the water spray angle θ of the sprinkler section 5 is made small, and the distance L of water spray is made constant regardless of the magnitude of the water spray pressure.

Therefore, if you want to increase or decrease the amount of water per unit area by actively adjusting the watering pressure according to the amount of snow, set the watering pressure to a small value and increase the watering angle θ based on when the amount of snow is small. Keep it
When the amount of snowfall increases, the watering pressure is increased and the watering angle θ is decreased to increase the amount of watering per unit area. In addition, if you want to deal with an unexpected situation in which the watering pressure is lower than the planned value, reduce the watering angle θ to a certain extent when the watering pressure is at the planned value. When the water is wet, increase the watering angle θ. It is also possible to combine both cases.

[Effects of the invention] The invention has the following effects. In other words, regardless of the magnitude of the watering pressure, the spraying distance can be kept constant and the watering area can be kept constant, so the watering pressure can be actively adjusted according to the amount of snow to increase or decrease the amount of watering per unit area. This makes it possible to obtain efficient snow melting effects. In addition, even in the event that the water spray pressure becomes lower than the planned value, the water spray area will not change, and the snow melting effect can be maintained over the entire area.
