The fog reduction and shielding system of roads and bridges by the water curtain of the present invention detects the concentration, direction, and speed of the fog in real time, thereby generating a water curtain sprayed with high pressure water supplied through the drainage. By reducing or blocking the fog flowing into the roads and bridges, there is an effect of promoting the safe operation of various transportation means.

Hereinafter, with reference to the accompanying drawings, the fog reduction and shielding system of the road and the bridge by the water curtain of the present invention will be described with reference to the embodiment as follows.

Fog reduction and shielding system of the road and bridge by the water curtain according to an embodiment of the present invention is the fog concentration observation step (S10), the flow direction of the fog and the movement speed measurement step as shown in Figure 1 and 2 (S20), a water curtain generation step (S30) and a water curtain generation stop step (S30).

Fog concentration observation step (S10) is a step of observing the concentration of the fog in real time by the visibility system 100 installed on the road and bridge, when the observation visibility by the visibility system 100 falls below a certain level (200m or less) The signal is output to the control unit C, and the ultrasonic wind direction anemometer 110 is operated by the control unit C to perform the inflow direction and the moving speed measurement step (S20) of the fog.

The measurement of the inflow direction and the moving speed of the fog (S20) is a step of measuring the inflow direction and the moving speed of the fog with the ultrasonic wind direction anemometer 110 when the fog concentration observation value by the visibility 100 falls below a set value. .

Here, the ultrasonic wind direction anemometer 110 is a three-dimensional ultrasonic wind direction anemometer, and since the ultrasonic method is adopted in the wind direction anemometer, there is an advantage that accurate measurement from the breeze to the strong wind is possible.

The water curtain generating step (S30) is a step of generating a water curtain on the road and bridge toward the fog direction by operating the water curtain generator 120 according to the measured value by the ultrasonic wind direction anemometer 110, water curtain generator The water curtain generated by the 120 is generated at every set interval on both ends of the road and the bridge at every set section of the road and the bridge.

On the other hand, the water curtain generating device 120 is installed at each of the set distance on the outer ends of the road and the bridge, respectively, the visibility system 100, the ultrasonic wind direction anemometer 110 and the water curtain generator ( 120 are respectively installed to generate independent water curtains at one end and the other end of the road and the bridge in the parallel and orthogonal and orthogonal directions of the vehicle and the end of the road and the bridge, depending on the direction of the inflow of the road and the bridge. That is, water curtains are generated at one end and the other end of the road and the bridge in the direction perpendicular to the direction of travel of the vehicle and at the set distance, so that the wind direction toward the sides of the road and the bridge and the fog direction toward the front and the rear of the road and the bridge are generated. It will block the inflow.

At this time, the water curtain generating device 120 includes a hydraulic pressure 122, a vertical pipe 126, a spray nozzle 124 and a water reservoir 128, as shown in Figure 3 and 4, in particular, the spray nozzle The vertical pipe 126 supporting the 124 is installed at a predetermined distance of 10m or more at one end and the other end of the road and the bridge. In addition, the water curtain generating region generated by the water curtain generating apparatus 120 is adjusted to partially overlap each other so that a gap does not occur.

A diaphragm is provided between the vertical pipe 126 and the vertical pipe 126 to shield the fog from the diaphragm.

The oil pressure machine 122 is a hydraulic pump, which is connected to the end of the conduit 126a connected to the injection nozzle 124 and sprays water supplied from the water reservoir 128 at high pressure to inject through the injection nozzle 124.

The injection nozzle 124 is detached to the upper end of the hollow-shaped vertical pipe 126 which is installed at a plurality of set intervals at one end and the other end of the road and the bridge, respectively, and is formed in a fan-shaped plate to spray water radially. A plurality of radial injection holes 124a are provided on the upper surface at each set interval, and a lower end of the connection part 124c is formed to be spirally fastened with the vertical pipe 126. Further, since the injection nozzle 124 should generate the water curtain in the direction parallel and orthogonal to the direction of travel of the vehicle, the jet port 124a is also installed to face the direction of travel and the direction perpendicular to the direction of travel of the vehicle. In particular, the injection nozzle 124 is installed so as to face in the direction perpendicular to the direction of travel of the vehicle is installed to face each set distance along both ends of the road and bridge to block the fog flowing back and forth from the middle of the road and bridge. .

Here, the lower end of the body 124a of the injection nozzle 124 is preferably formed at 120 °, and the diameter of the injection hole 124a is defined to be about 0.2 mm, and thus the diameter of the injection hole 124a may be changed.

The water reservoir 128 is connected to the drainage channel to supply water in a drainage channel (not shown in the drawing) to generate a water curtain, and a pump is installed.

Meanwhile, the visibility system 100, the ultrasonic wind direction anemometer 110, and the oil pressure 122 are controlled by the control unit C, respectively, and the result value according to the fog concentration observation through the visibility system 100, the ultrasonic wind direction anemometer 110. The control unit determines whether or not the operation of the oil pressure 122 is received by receiving the result value according to the fog inflow direction and the moving speed measurement.

The water curtain generation stop step (S30) is to perform the water curtain generation step (S30) as shown in Figure 1 and 2 to block the flow of fog into the road and bridge, while the concentration of the fog by the visibility 100 When the real-time observation value rises above the set value 200m, the water curtain generator 120 is stopped.

Therefore, the fog reduction and shielding system of the road and the bridge by the water curtain according to the present invention first observes the concentration of the fog in real time by the visibility system 100 installed on the road and the bridge, the observation visibility is below a certain level (200m Or below), it outputs a signal to the controller C.

Next, after measuring the inflow direction and the moving speed of the fog with the ultrasonic wind direction anemometer 110 according to the signal of the control unit (C) operates the water curtain generating device 120 on the road and bridge according to the moving direction of the fog. .

At this time, when the oil pressure 122 is operated by the signal of the control unit C, the water stored in the water reservoir 128 moves to the vertical pipe 126 along the pipeline 126a and the injection nozzle installed at the end of the vertical pipe 126. High pressure water is sprayed through 124 to create an air curtain thereby reducing and blocking the incoming mist.

On the other hand, when the inflow direction of the fog flows into the road and bridge at one end (the other end), the water curtain generating device 120 located at one end (the other end) is operated, and when the water flows into both ends, the water curtain generating devices are located at both ends. Operate the 120 at the same time to reduce or block the fog. At the same time, when the inflow direction of the fog flows in any one of the road and the longitudinal direction of the bridge (transfer direction of the transport means) to operate the water curtain generating device 120 located in the inflow direction.

Next, when the real-time fog concentration observation value by the visibility system 100 rises above the set value 200m, the signal is sent to the control unit C and the control unit C stops the water curtain generator 120. .
