DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of an anemometer with a pressure intake and an anemometer according to the present invention will be described below.

FIG. 1 is a front view showing a main part of a wind direction anemometer with an air pressure intake according to the present embodiment, and FIG. 2 is a top view. In these figures, reference numerals 1 and 2 denote guide plates, 3 is a cup, 4 is an air intake, 5 is a support, 6 is an arrow blade, 7A to 7A.
D is a support rod, 8 is an inner tube, 9 is an air pressure introducing tube, 10 is an angle detector, and 11 is a rotation detector.

The guide plates 1 and 2 are formed in an elliptical shape, and are separated by a predetermined interval (the length of the support rods 7A to 7D) by interposing support rods 7A to 7D of the same length. They are arranged facing each other. The support rods 7A to 7D are arranged at four locations near the periphery of the guide plates 1 and 2, and the two guide plates 1 and 2 are provided.
Are integrally fixed in a facing state. The guide plates 1 and 2 thus integrally fixed by the support rods 7A to 7D.
Among them, a cylindrical column 5 is rotatably connected to a central portion of one (lower side) guide plate 2 in an orthogonal state.

On one peripheral edge of each of the guide plates 1 and 2 formed in an oval shape in the longitudinal direction, arrow blades 6 and 6 are fixed vertically to the guide plates 1 and 2, respectively. In addition, a cup 3 is provided between the guide plates 1 and 2 so that the rotation surface thereof is set parallel to the guide plates 1 and 2. The cup 3 is fixed to a rotating shaft 3 a provided between the guide plates 1 and 2 so as to be coaxial with the support column 5, so that its rotation surface is parallel to the guide plates 1 and 2 and the guide plates 1 and 2. It is set to be halfway between the two.

Further, each opposing surface 1 of the guide plates 1 and 2
At a substantially central portion of the opposing surface 1a of the guide plate 1 among the a and 2a, an air pressure intake 4 is formed so as to open to the opposing surface 1a. The pressure inlet 4 communicates with a barometer (not shown). For example, in the present embodiment, a conduit communicating with the air pressure inlet 4 is formed inside each of the guide plate 1 and the rotating shaft 3a. It communicates with a barometer.

An inner tube 8 is provided coaxially inside the support column 5, and a pressure introducing tube 9 is provided coaxially inside the inner tube 8. The upper end of the inner pipe 8 is fixed to the center of the guide plate 2 in the support 5 in an orthogonal state, and the upper end of the air pressure introducing pipe 9 is similarly rotated in the support 5 to which the cup 3 is fixed. It is fixed to the shaft 3a.
That is, the inner pipe 8 rotates around the axis according to the direction of the guide plates 1 and 2 to which the arrow blades 6 and 6 are fixed, that is, the wind direction, while the air pressure introducing pipe 9 rotates the rotation of the rotary shaft 3a, that is, the wind speed. It is designed to rotate around the axis in accordance with.

At the end of the inner tube 8, an angle detector 10 for detecting a wind direction based on the rotation angle of the inner tube 8 is provided, and at the end of the air pressure introducing tube 9, a pressure introducing tube 9 is provided. A rotation detector 11 for detecting the wind speed by detecting the rotation speed of the motor is provided. Further, the support column 5 is vertically fixed to the ground surface, so that the guide plates 1 and 2 are in a horizontal state.

Next, the operation of the wind direction anemometer with the air pressure intake constructed as described above will be described in detail.

Since the guide plates 1 and 2 are provided with arrow blades 6 and 6 at one peripheral edge in the major diameter direction, when the wind blows, as shown in the figure, the guide plate 1 has an oval shape. ,
The major axis direction of 2 is always parallel to the wind direction. Further, since each of the guide plates 1 and 2 is horizontally opposed to each other with a predetermined distance (length of the support rods 7A to 7D), wind is applied between the guide plates 1 and 2. , 2 in the major axis direction (the one without the arrow blades 6, 6) and blows through to the other (the one with the arrow blades 6, 6).

That is, even when the wind blows up from below (surface side) or blows down from above,
The wind passing through the air pressure inlet 4 provided substantially at the center of the guide plates 1 and 2 has a horizontal flow, and the wind acting on the cup 3 provided at the center of the guide plates 1 and 2 also has a horizontal flow. Therefore, only the static pressure acts on the air pressure inlet 4 irrespective of the direction of the wind, so that the accurate pressure is measured by the barometer, and the cup 3 also detects the speed of the horizontal flow. Detects the exact wind speed. Further, since the air pressure inlet 4 and the wind direction / wind speed function are integrated, the installation and the like are easy and the cost can be reduced.

The present invention is not limited to the above embodiment, and for example, the following modifications can be considered. (1) In the above embodiment, the wind direction anemometer with the air pressure inlet has been described. However, the present invention is also applicable to an anemometer in which the wind direction detection function is deleted by removing the arrow blades 6 and 6. Further, it is needless to say that the present invention can be applied to an anemoscope having no wind speed detecting function.

(2) In the above embodiment, the air pressure inlet 4 is provided on the facing surface 1a of the guide plate 1, but may be provided on the facing surface 2a of the guide plate 2 located below. The position of the air pressure inlet 4 may be any position on the facing surface 1a or the facing surface 2a as long as the position does not receive the dynamic pressure of the wind. It is also conceivable to provide a plurality of air pressure inlets 4 on the same guide plate 1 or guide plate 2.

[0018]

As described above, according to the anemometer with the air pressure intake and the anemometer according to the present invention, the following effects can be obtained.

(1) According to the first aspect of the present invention, even when the wind blows up or down, the cup detects the wind speed between the horizontally arranged guide plates, that is, the wind flowing horizontally. Therefore, it is possible to prevent an error from occurring in the wind speed detected depending on the wind direction, thereby improving the measurement accuracy of the wind speed. Further, since the air pressure inlet is provided on the opposing surface of the guide plate, the direction of the wind is the same (parallel) as the opening surface of the air pressure inlet, and thus the accuracy of the air pressure measurement can be improved. Further, since the air pressure inlet and the anemometer are integrated, the installation and the like are easy and the cost can be reduced.

(2) According to the second aspect of the invention, even if the wind blows up or down, the cup detects the wind speed between the horizontally arranged guide plates, that is, the wind flowing horizontally. Therefore, it is possible to prevent an error from occurring in the wind speed detected depending on the wind direction, thereby improving the measurement accuracy of the wind speed. Further, since the air pressure inlet is provided on the opposing surface of the guide plate, the direction of the wind is the same (parallel) as the opening surface of the air pressure inlet, and thus the accuracy of the air pressure measurement can be improved. Furthermore, since the air pressure intake, the anemometer and the anemometer are integrated, the installation and the like are easy and the cost can be reduced.
