As shown in FIG. 2, the wind tunnel reducing facility 100 according to the embodiment of the present invention may include a wind sensing sensor 190.

The wind sensing sensor 190 can be installed inside the tunnel 200 to sense the wind direction and can detect wind direction of the tunnel wind pressure reduction facility 100 according to the wind direction sensed by the wind direction sensor 190. [ Can be controlled.

Meanwhile, the wind sensing sensor 190 may be implemented by various known types of weather vanes, and the wind sensing sensor 190 has a well-known configuration, and thus a detailed description thereof will be omitted.

The operation and effect between the above-described respective constitutions will be described.

The wind pressure reduction facility 100 of the tunnel according to the embodiment of the present invention has a structure in which wind does not flow in the tunnel 200 in order to minimize wind blowing in a direction facing the tunnel 200 when the vehicle enters the tunnel 200, When the wind is blown to the inlet 210 side from the outlet 230 side of the tunnel 200, the operation may be different according to two cases.

5, when the wind is not detected by the wind sensor 190, since the air is hardly moved within the tunnel 200, The wind pressure due to the speed of the vehicle may act on the vehicle.

In order to compensate for this, the inlet blower 135 operates to suck air at the inlet 210 side of the tunnel 200 when the wind sensor 190 detects wind with less than a preset air volume, and the outlet blower 145 Operates to discharge air toward the outlet 230 side of the tunnel 200. [ Then, the switching damper 185 closes the air jet line 180, and the door rotates so that the air transfer portion 170 and the outlet blower 145 are communicated.

When the inlet blower 135, the outlet blower 145 and the switching damper 185 operate, the air on the inlet 210 side of the tunnel 200 flows into the inlet hopper 130 by the inlet blower 135 And the inflow air is discharged from the inlet blower 135 and transferred to the air delivery unit 170.

The air introduced into the outlet blower 145 through the air transmission unit 170 is discharged to the outlet 230 of the tunnel 200 through the outlet hopper 140 by the outlet blower 145.

The switching damper 185 closes the air injection line 180 so that all of the air delivered to the air delivery portion 170 is discharged to the outlet 230 side of the tunnel 200 by the outlet blower 145 do.

When the air is discharged from the inlet 210 side of the tunnel 200 toward the outlet 230 side, the air on the inlet 210 side of the tunnel 200 is guided to move toward the outlet 230 side of the tunnel 200, The wind is generated from the entrance 210 side of the tunnel 200 toward the exit 230 side so that the wind is generated in the same direction as the traveling direction of the vehicle and the wind pressure applied to the vehicle entering the tunnel 200 can be minimized have.

That is, it is possible to minimize the wind pressure generated when the tunnel 200 is generated by generating wind in the same direction as the traveling direction of the vehicle, and also to prevent the wind (wind) 210 and the outlet 230 to maximize the ventilation and generate wind in the form of pushing the vehicle from the rear, thereby assisting the running of the vehicle.

6, when the wind sensing sensor 190 senses a wind blowing from the outlet 230 side of the tunnel 200 toward the inlet 210 side, the entrance 210 of the tunnel 200 is detected, The speed of the vehicle at the time of entering the vehicle and the wind pressure facing the vehicle can cause a great wind pressure to be applied to the vehicle.

In order to compensate for this, when the wind sensing sensor 190 senses a wind blowing from the outlet 230 side of the tunnel 200 toward the inlet 210 side, the inlet blower 135 does not operate and the outlet blower 145 does not operate. And the switching damper 185 operates so that the door closes the air delivery portion 170 and opens the air jet line 180. [

The air pressure reducing facility 100 of the tunnel operated in this way sucks the air on the outlet 230 side of the tunnel 200 through the outlet hopper 140 by the outlet blower 145 and the sucked air passes through the switching damper 185, The air is supplied to the air injection line 180 without being transferred to the air transmission portion 170 by the air injection line 180 and forms an air curtain at the outlet 230 side of the tunnel 200 through the air injection line 180.

When air is generated from the outlet 230 side of the tunnel 200 toward the inlet 210 as described above, air is sucked by the outlet blower 145 and air curtains are formed by the air jet line 180, The wind facing the vehicle can be minimized and the wind pressure applied to the vehicle can be minimized.

Meanwhile, when rain and rainwater are introduced, the outlet hoppers 140 and the inlet hoppers 130 are provided with drain ports 131 and 141 to drain rainwater, thereby preventing the occurrence of faults due to the inflow of rainwater.

Therefore, the wind pressure reducing facility of the tunnel 200 of the present invention can block the wind blowing from the outlet 230 side of the tunnel 200, thereby reducing the impact due to the wind pressure applied to the vehicle when entering the tunnel 200 have.

In addition, when there is no air movement in the tunnel 200, the inlet blower 135 and the outlet blower 145 operate together to induce generation of wind in the same direction as the traveling direction of the vehicle, The wind pressure applied to the vehicle can be minimized.

Also, it is installed on the bottom of the tunnel 200 and is easy to install, and it is easy to manufacture and the manufacturing cost can be reduced.

In addition, the entrance grating 150 and the exit grating 160 are installed to guide the movement of the air, and also generate vibrations in the vehicle to inform the driver of the entrance and exit of the tunnel 200, .

In addition, the inlet hoppers 130 and the outlet hoppers 140 are provided with drain ports 131 and 141 to prevent the occurrence of faults due to inflow of rainwater.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And all changes and modifications to the scope of the invention.
