4 to 6 are views of a state in which the hydrant frost prevention device 300 according to an embodiment of the present invention is applied to the artificial snow spraying system 100.

As shown in FIG. 4, one end of the first connector 310 is assembled to the hose connector 142 provided at the top of the feeder 140, and the second connector 320 is provided at the top of the feeder 130. One end is assembled to the hose connector 132. In the process of assembling the first connector 310 and the second connector 320, the operator locks the end of the first connector 310 and the second connector 320 to one of the

hose connectors

142 and 132. The means 312 and 322 are operated to maintain the assembled state.

Thereafter, as shown in FIGS. 4 and 5, the water hose 210 and the air hose 220 are connected. 5 is a state in which the water hose 210 and the air hose 220 are connected, water is supplied from the water supply 130 while air is supplied from the feeder 140. The water and air supplied in this way passes through the snowplow 200 to form artificial snow.

6 is a view showing a state for discharging the water that can remain in the water supply after the artificial snow is sprayed, Figure 7 is discharged water remaining in the water supply by the hydrant frost prevention device according to an embodiment of the present invention This figure shows the state.

As shown in FIG. 6, the water hose 210 and the air hose 220 connected to the water supply 130 and the power supply 140 may be removed or may not be removed.

First, the operator operates the water blocking handle 134 provided at the top of the water supply 130 so that the water supply through the water supply 130 is no longer made. At this time, the air shutoff lever 144 provided at the upper portion of the feeder 140 is in an open state.

And the operator operates the switch lever 316 of the three-way valve provided in the first connector 310 so that the air passing through the feeder 140 is directed toward the residual water discharge induction air line 330 side.

The pressure of the air discharged to the outside after passing through the second connector 320 through the induction air line 330 for discharging residual water is relatively high pressure and the water remaining in the water supply 130 is relatively low pressure. Some of the high pressure air introduced into the second connector 320 is discharged directly to the outside of the second connector 320 while a part of the high pressure air is introduced into the water supply 130 and then again of the second connector 320. The discharge is made to the outside. In this process, as shown in FIG. 7, the water remaining inside the water supply 130 (indicated by the solid arrows in the drawing) is drawn up by the high-pressure air (indicated by the dashed arrows in the drawings) together with the air. It is discharged to the outside.

Therefore, there is no fear that the water supply 130 freezes or freezes because there is no water remaining in the water supply 130. On the other hand, when the high pressure air is supplied through the air line 330 for inducing residual water so that the water remaining in the water supply 130 is discharged while the water hose 210 is connected to the water supply 130. In the water remaining in the water hose 210 is also discharged as it is possible to facilitate the operator to manage the water hose 210 after the snow spraying.

As described above, after the supply of water and air for the formation of artificial snow, the water supply freezes or freezes as the water remaining in the water supply 130 is forced out to the outside using high pressure pneumatic pressure. Can be prevented in advance.

In particular, the hydrant frost prevention device according to an embodiment of the present invention can be made in a modular form to be applicable to the existing snow spraying system as well as the existing snow spraying system can be easily installed and maintained accordingly. have.
