While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

Like reference numerals are used for like elements in describing each drawing. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

The present invention can provide a weather vane which is simple in structure and easy to manufacture, and can sense a more precise wind direction.

The weather vane according to the present invention includes a wind deflector plate 10 rotated by the wind shown in FIGS. 1, 3, 4, and 6 to indicate the wind direction;

A magnet 20 disposed in the middle of the wind deflector; And a magnetic sensor 30 for sensing the direction of the magnet according to the direction change of the wind deflector.

Of course, the weather vane of the present invention configured as above may further include a computer having a program capable of calculating the wind direction by reminding the change of the top detected by the magnetic sensor 30, and the wind direction plate, Magnetic sensors are a means of sensing the direction of physical winds.

That is, when the wind deflector 10 rotates by wind and supports a specific direction, the direction of the N pole and S probe of the magnet 20 installed on the wind deflector plate is different, and as the direction of the magnet is changed, A change in magnetic field sensed by the magnetic sensor 30 is detected and the direction of the wind can be sensed by comparing the magnetic sensor with a predetermined reference value provided in the computer program.

The magnetic sensor 30 may be any one of a variety of sensors capable of sensing the direction of the magnet as described above, but preferably a magnetic rotary encoder may be used.

The wind deflector 10 is a means for indicating wind direction, and may be formed in various shapes. However, it is preferable that the wind deflector 10 is made as light and small as possible so as to be sensitive to wind.

As shown in the enlarged view of FIG. 4, the wind deflector 10 is a wind deflector 10 which is pivotally driven by a bearing 11 around a rotary shaft 10s coupled to a bottom plate 40, A balancing portion 10b formed on the opposite side of the eave blade portion and formed to be shorter than the eave blade portion and a balancing portion 10b formed on the opposite side of the balancing portion 10b with respect to the rotation axis 10s And a hoop balancing portion 10g for extending the center of gravity of the balance maintaining portion and the eccentric wing portion which are elongated and are short in length.

It is preferable that the eaves wing 10a is as wide and thin as possible so as to be sensitive to the wind. Accordingly, as shown in the figure, it is formed wider and longer than the balance holding portion 10b.

However, when the eccentric wing portion 10a is formed to be wide and long, the center of gravity of the eccentric wing 10a is not aligned with the center of gravity of the balance holding portion 10b, so that the rotary shaft 10s can be inclined to one side. When the rotary shaft is inclined, Since the plate may not be smoothly operated, it is preferable that both sides of the rotation axis 10s are balanced.

A thick hoop balancing portion 10g is formed so as to face the balancing portion 10b with respect to the rotating shaft 10s so as to compensate for the weight of the wider eaves 10a.

The hoop balancing portion 10g is thicker than the other portions and is formed by extending the weight toward the balancing portion 10b as shown in Fig. I was able to compensate for the weight.

1 and 4, the wind deflector 10 is rotatably installed at the center of a bottom plate 40 by a bearing 11, and the magnet 20 is installed at an upper center of the wind deflector 10, The magnetic sensor 30 is installed at the center of the top plate 50 and senses the magnetic force of the magnetic sensor 30 according to the direction of the magnet which is changed in direction by the rotation of the wind deflector.

2, 3 and 5, the top plate 50 extends outside the end portion of the wind deflector plate 10 to protect the wind deflector plate 10 from rain or snow. That is, as shown in the drawing, the width of the top plate 50 is sufficiently wide so that the wind direction plate is less influenced by the snow and the rain when the snow or rain is blown from the side.

In addition, the bottom plate 40 has a bearing 11, which forms a slope so as to be gradually lowered from the center toward the magnetic field position, and which allows the snow or rain flowing between the top plate and the bottom plate to flow outward, Thereby preventing the function thereof from being deteriorated by moisture.

A plurality of supports 45 may be provided at the edges of the bottom plate 40 and the top plate 50 so that the distance between the two plates is maintained. Thereby blocking the flow of air into the inside.

The weather vane configured as described above can protect the magnetic sensor 30 provided on the top plate by further providing a cover plate 51 on the top plate 40. The position and operation state of the weather vane on the cover plate 51 It is possible to further include a display lamp 52 to inform the user. Of course, one side may further include a space in which a communication module or a controller for transmitting a signal sensed by the magnetic sensor to an external computer is installed.

The weather vane configured as described above may be used alone, but it is preferably used in combination with an anemometer.

Accordingly, the weather vane of the present invention can be constructed in combination with an anemometer, and such an anemometer 60 is as shown in Figs. 5 and 6. Since the weather vane is already constructed as described above, detailed description is omitted.

The anemometer with the weather vane according to another aspect of the present invention is provided with a weather vane configured as described above and detects the wind speed by the number of rotations of the rotating body sensed by the rotation sensing means for sensing the rotation of the rotor 61 And a plurality of guide blades (62) formed radially around the center of the plurality of rotary blades constituting the rotary body (61) and having at least one arcuate shape in plan view, The wind is more effectively transmitted to the rotary vane, and foreign matter from the outside is prevented from flowing into the rotary vane.

The technique related to such an anemometer is disclosed in patent application No. 1142553 filed and registered by the applicant of the present invention, but brief description will be made below for the understanding of the present invention.

6, the rotating body 61 is provided with a plurality of rotating blades 61w, and each of the rotating blades 61w preferably has a shape of a bow bent in a direction in which wind flows in Do.

By forming the rotary vane 61w in this manner, the rotary body 61 rotates even in a slight wind and can sense the wind.

Further, the guide vane 62 is guided at an acute angle with the center line passing through the center of the rotating body 61 and directed to the inside of the arc-shaped rotary vane of the rotating body, and both sides are formed into arc- The sensitivity of the rotating body can be increased.

The rotation sensing means (not shown) may be modified in various ways, but preferred examples thereof include light emitting means for emitting light to a light transmitting hole formed in a rotating shaft of the rotating body 6, And an optical sensor composed of a light receiving means for sensing light passing through the optical fiber.

That is, when the rotating shaft rotates by the rotation of the rotating body, when the light emitted from the light emitting means meets the light transmitting hole, the light passes through the light transmitting hole and is incident on the light receiving means. The light receiving means senses the incident light, And the speed of the computer can be detected. The computation program of the computer can calculate the wind speed from the sensed number of light senses and the interval.

The guide vane 62 is integrally formed on one surface of the support plate 63 and the opposite end of the guide vane 62 is integrally formed with the weather vane The upper plate or the lower plate may be defective.

A lower plate 50 constituting a weather vane is assembled and integrated at an end of a guide vane 62 formed integrally with the support plate 63. As shown in FIG.
