And a blower fan 23 to be supplied.
[0013]
Next, the operation of the rain prevention device for rainwater and the like according to this embodiment based on the above configuration will be described. If it suddenly rains during the competition in the stadium, the rain sensor 3 detects the rain and outputs a rain detection signal to the control unit 4. This control part 4 starts the ventilation fan 23 of the blowing apparatus 2 based on a rain detection signal.
[0014]
When the blower fan 23 is activated, air is supplied to the opening 21 through the duct 22, and the air is blown from the opening 21 to the sky above the outdoor protection area 13 at an angle φ and a predetermined speed. If this blowing is the vector FA and the raindrop is the vector FG, the blowing force acts on the raindrop and the raindrop is scattered in the direction of the vector FP.

The wind direction guide plate 25 has a configuration in which a plurality of blade bodies are rotatably supported in the opening of the opening portion 21, and the plurality of blade bodies are driven and controlled by a motor 26 to adjust the blowing direction from the opening portion 21. is there. The wind direction guide plate 25 may be configured to adjust the blowing direction in the left-right direction and also in the up-down direction.
[0018]
Next, the operation of the rain prevention device for rainwater and the like according to this embodiment based on the above configuration will be described. First, as in the case of the first embodiment, the rain sensor 3 detects whether or not there is rain in the outdoor protection area 13 and outputs a rain detection signal, and the wind direction sensor indicates what direction the wind is. 5 and outputs a wind direction detection signal.
[0019]
Each rain detection signal and wind direction detection signal are input to the control unit 4, and the control unit 4 activates the blower fan 23 and the motor 26, respectively, and performs air blowing in a predetermined air volume and a predetermined blowing direction from the opening 21 of the blowing device 2. To do. The predetermined air volume of the air blow is determined by the rain state, for example, the size of raindrops, the rain density, the rainfall amount and the like.
[0020]
The blowing direction of the air blow is determined by the direction of the wind blowing into the outdoor protection area 13. For example, as shown in FIG. 4A, in the case of a wind direction from the right side, which is a right-and-left direction, if the wind force is the vector FW1 and the raindrop is the vector FG1, the combined raindrop vector is FG2. With respect to the raindrop of the raindrop combined vector FG2, the blowing direction from the blowing device 2 is the combined airflow vector FA2 from the wind force vector FW1 and the wind vector FA1 when there is no wind.
[0021]
Accordingly, the force of the vector FP can be applied to the raindrop from the raindrop combined vector FG2 and the blown combined vector FA2. Since it is possible to urge the raindrops with the same vector FP as in the case where it is assumed that there is no wind in this way, rainwater that falls into the outdoor protection region 13 is sent to fields other than the outdoor protection region 13 as in the case of the above embodiment. It can be scattered to the region 14.
[0022]
Also, as shown in FIG. 4B, when the wind direction is from the angle θ forward and diagonally to the right, if the wind force is the vector FW2 and the raindrop is the vector FG1, the combined raindrop vector is FG3. The direction of the blowing from the blowing device 2 is the combined vector of the blow FA3 from the wind force vector FW2 and the blow vector FA1 when there is no wind.
[0023]
Therefore, from the raindrop combined vector FG3 and the blown combined vector FA3, the force of the vector FP can be applied to the raindrop. As in the case of FIG. 5A, rainwater entering the outdoor protection area 13 is scattered to prevent the rain in the outdoor protection area 13 from getting wet.
