  As shown in the drawing, the wind condition detector 10 includes an attachment part 20 fixed at a predetermined place, a round bar-like support member 30 supported by the attachment part 20 so as to be rotatable about an axis in the vertical direction, and a wind direction. The first wind receiving portion 40, the second wind receiving portion 50 that tilts around the horizontal axis with respect to the support member 30 and is inclined more horizontally as the received wind speed is faster, and wind of a predetermined wind speed or higher. An alarm unit 60 (not shown in FIG. 3) that emits an alarm sound when received is provided.

[Mounting part]
The attachment portion 20 is substantially cylindrical and is fixedly installed on a horizontal plane at a predetermined installation position so that the center line thereof faces in the vertical vertical direction.
A flange portion 21 is provided at the lower end portion of the attachment portion 20, and a plurality of screw insertion holes 25 are formed in the flange portion 21. And the attachment part 20 is fixed by screwing or bolting on a horizontal surface through the several screw insertion hole 25 of the flange part 21. As shown in FIG. If the installation strength can be sufficiently secured, the flange portion 21 may be installed by adhesion, welding, or the like.

  Further, a bottomed center hole 22 into which a round bar-like support member 30 can be inserted is formed at the center of the upper surface of the mounting portion 20. Two bearings 23 and 23 are built in the upper and lower portions of the mounting portion 20, and the support member 30 inserted into the center hole is rotatably supported by these bearings 23 and 23. Further, a hard ball 24 is disposed on the inner bottom portion of the center hole 22, and a recess on the lower end portion end surface of the support member 30 abuts on the spherical surface of the ball 24, and the support member 30 is centered by the overall weight of the center hole 22. Even if it is pressed against the inner bottom surface, it is possible to rotate smoothly with reduced friction.

[Support member]
The support member 30 is a round bar having a uniform outer diameter, and a lower end portion thereof is supported by the attachment portion 20 in a state parallel to the vertical vertical direction.
The support member 30 fixedly supports the first wind receiving portion 40 and the alarm portion 60, and supports the second wind receiving portion 50 so as to be rotatable about a horizontal axis.
Then, due to the wind pressure received by the first wind receiving portion 40, the support member 30 rotates around itself with the first wind receiving portion 40.

[First wind receiver]
The first wind receiving portion 40 is a flat plate, and one end thereof is fixed to the support member 30 so that the flat plate surface is parallel to and substantially flush with the support member 30. Then, as shown in FIG. 2, the first wind receiving portion 40 extends outward in the radial direction with the support member 30 as the center, and when the first wind receiving portion 40 receives wind pressure, It turns and it will be in the state which faced the direction in which the 1st wind receiving part 40 points to a leeward with respect to the support member 30. FIG. That is, the wind direction can be easily recognized visually by the direction of the first wind receiving portion 40.

In addition, the first wind receiving portion 40 has a fan shape with a flat plate shape having an angle range of 90 degrees, and the center side of the fan shape is cut out into a smaller fan shape. A support shaft 51 is provided at the central position of the fan shape formed by the first wind receiving portion 40 so as to rotatably support the second wind receiving portion 50 in the support member 30. One rotating end of the receiving portion 50 rotates along the circumferential direction of the sector of the first wind receiving portion 40.
The flat surface of the first wind receiver 40 is divided into three regions 41 to 43 along the sector-shaped circumferential direction, and each region is given a different color. As will be described later, the rotation angle of the second wind receiving portion 50 changes according to the wind speed received, and the direction indicated by the rotation end of the second wind receiving portion 50 is the flat surface of the first wind receiving portion 40. The degree of wind speed is indicated by which one of the three areas 41 to 43 belongs to.
The rotating end portion of the second wind receiving portion 50 is closer to the downward direction as the wind speed is lower, and is closer to the horizontal direction as the wind speed is higher. Of the three regions 41 to 43 of the flat surface of the first wind receiving portion 40, the lowermost region 41 is colored white in the low speed region, and the region 42 above is colored yellow in the medium speed region, The uppermost region 43 is colored red in the high speed region. Moreover, the display of these three area | regions 41-43 is performed similarly on both surfaces of the flat plate surface of the 1st wind-receiving part 40. FIG.
As a result, the first wind receiving portion 40 also functions as a “wind speed display portion” that displays the wind speed region according to the position of one end of the second wind receiving portion 50.

  In addition, each angle range of the three areas 41 to 43 on the flat plate surface of the first wind receiving portion 40 indicates an appropriate or inappropriate wind speed range of the action performed by receiving the wind. For example, when the wind state detector 10 is installed at a place where work at a high place is performed, a region 41 that is a low speed region indicates a range of wind speeds at which work at a high place can be appropriately performed, A region 42 that is a medium speed region indicates a range of wind speed that requires attention in high-altitude work, and a region 43 that is a high-speed region indicates a range of wind speed that is inappropriate for high-altitude work (operation prohibited range).

[Second wind receiver]
The second wind receiving portion 50 is rotatably supported by a support shaft 51 that is horizontally oriented on the support member 30.
The second wind receiving portion 50 has a flat plate shape, and the flat plate shape is substantially a ginkgo shape as shown in FIGS. That is, one rotating end portion with the support shaft 51 sandwiched is an isosceles triangle shape that gradually widens toward the end portion (hereinafter referred to as the widened end portion 52). The end portion maintains a substantially constant narrow width as a whole and the tip end portion is rounded (hereinafter referred to as a narrow end portion 53).
Further, the widened end portion 52 of the second wind receiving portion 50 has a slit portion 54 formed at the center in the width direction, and the first wind receiving portion 40 is inserted into the slit portion 54. Yes.

Since the second wind receiving portion 50 is generally plate-shaped with a uniform thickness, the widened end portion 52 is heavier than the narrowed end portion 53, and the widened end portion 52 side is almost directly below in the absence of wind. It will be in the state. On the other hand, since the widened end 52 has a shape that becomes wider toward the rotating end, the area of the flat plate surface is large, and when the wind is received, the narrowed end 53 is rotated in the direction of lowering against gravity. As the wind speed increases, it approaches the horizontal state.
As shown in FIG. 3, the widened end portion 52 is formed in a triangular blade shape on both sides of the slit portion 54, and the widened end portion becomes smaller as the inclination angle θ on the rotating end portion side of the blade is decreased. The area of the flat surface of the part 52 can be increased, and the sensitivity to wind can be changed. Accordingly, a plurality of types of second wind receiving portions 50 having different inclination angles θ at both ends in the width direction of the widened end portion 52 are prepared, the second wind receiving portion 50 having an appropriate sensitivity is selected, and the support member is selected. 30 may be attached. Further, a plurality of types of second wind receiving portions 50 having different lengths from the distal end portion of the narrow end portion 53 to the support shaft 51 may be prepared and appropriately selected.

The second wind receiving portion 50 includes reflecting portions 55 and 55 having a reflecting surface on the lower surface when the wind of the widened end portion 52 is received and the plate is rotated horizontally.
As described above, since the second wind receiving portion 50 is arranged such that the first wind receiving portion 40 is inserted into the slit portion 54, the inner edge portion of the slit portion 54 is the first wind receiving portion 40. It is close to the display of the three areas 41 to 43 showing the three-stage wind speed areas formed on both sides of the. For this reason, it can be visually recognized easily which wind speed region belongs to which of the three regions 41 to 43 the inner edge portion of the slit portion 54 belongs to.
However, when the wind state detector 10 is mounted at a high place and is looked up from below, the flat surface of the first wind receiving portion 40 is along the vertical direction, so that it is difficult to see from the angle or the mounting portion 20 or the mounting portion 20 is attached. It may be difficult to see because it is hidden in the place.
Therefore, when the reflecting portions 55, 55 are provided on the lower surface of the widened end portion 52, the display of the three areas 41 to 43 formed on both surfaces of the first wind receiving portion 40 is reflected downward, and the current wind speed is It is possible to visually recognize easily whether it belongs to the wind speed range from below.
The reflecting portions 55 and 55 may be formed on the entire lower surface of the widened end portion 52, but are desirably formed at least in a region in the vicinity of the first wind receiving portion 40, and a sufficient reflection range is ensured. If possible, as shown in FIG. 2, it is not necessary to form it in the vicinity of both end portions in the width direction of the widened end portion 52.

[Alarm part]
Two alarm parts 60 are provided above the first wind receiving part 40 via an L-shaped support base 61 that is fixedly installed in an installed state from the upper end part of the first wind receiving part 40 to the support member 30. It has been.
As shown in FIG. 4, each alarm unit 60 has a quadrangular columnar appearance and penetrates from one end to the other end in the longitudinal direction. The alarm unit 60 has a so-called whistle member structure. That is, at one end of the alarm unit 60, the opening 62 gradually decreases in width toward the other end, the nozzle 63 connected to the opening 62, and the diameter suddenly increases in connection with the nozzle 63. The enlarged diameter portion 64 is formed side by side, and in the middle of the enlarged diameter portion 64, a pair of wind passage plates 65, 65 are provided as opposed to each other while forming a slight gap.

The alarm unit 60 is disposed along the same direction as the first wind receiving unit 40 with respect to the support member 30, and the end on the opening 62 side faces the support member 30 side. Thus, when the first wind receiving unit 40 receives wind, the alarm unit 60 is in a state where the longitudinal direction thereof is parallel to the wind direction and the opening 62 side faces the windward side.
Then, the wind enters from the opening 62, and a free jet that is narrowed down through the nozzle portion 63 is blown to the position of the gap between the wind passage plates 65 and 65 in the enlarged diameter portion 64, and is generated at that time. A warning sound is generated from the wind passage plates 65 and 65 by the turbulent airflow.
The frequency of this alarm sound varies depending on the width A of the nozzle portion 63 shown in FIG. 4, the distance B from the end of the nozzle portion 63 to the air passage plates 65 and 65, and the overall length L of the enlarged diameter portion 64. The numerical values of the width A, the distance B, and the total length L are appropriately selected so as to be a listening sound band.
In the alarm unit 60, the width A and the distance B are adjusted so that an alarm sound is generated at a wind speed that is a lower limit value of the high speed range of the first wind receiving unit 40.

The alarm unit 60 may be directly or indirectly connected to the support member 30 so that the alarm unit 60 is always parallel to the wind direction and the end on the opening 62 side faces the windward, and is limited to the above arrangement. Not. For example, the upper end portion of the support member 30 may be fixedly installed in the same direction as the first wind receiving portion 40.
In addition, the shape of the alarm unit 60 is not limited as long as a structure that rings can be secured. For example, the external shape is not limited to a quadrangular prism shape, and may be a cylindrical shape. Further, the ringing mechanism is not limited, and other whistle member structures may be used. For example, the vibration sound of the air generated by the vibration of the wind passage plates 65 and 65 when the wind is received may be used, or the air current is caused to flow from the wind inlet to the inner peripheral surface of the cylinder. A 6-shaped whistle structure in which an alarm sound is generated by the edge of the opening through which the valve passes may be adopted.
In any case, it is preferable that the alarm unit 60 be a mechanism that emits sound by using wind force, so that the wind state detector 10 can be operated without power.

[Function and effect of wind condition detector]
The operation of the wind state detector 10 having the above configuration will be described.
For example, the wind state detector 10 is installed at a high place so that the support member 30 is parallel to the vertical vertical direction. When the first wind receiving portion 40 receives wind at a high place, the first wind receiving portion 40 is parallel to the wind direction and the first wind receiving portion 40 is on the leeward side with respect to the support member 30. As described above, the support member 30 and the first wind receiving portion 40, the second wind receiving portion 50, and the alarm portion 60 supported thereby rotate around the vertical vertical axis.

Further, the second wind receiving portion 50 rotates around a horizontal support shaft 51, and the widened end portion 52 rotates upward to an angle corresponding to the wind speed. The wind speed region can be visually confirmed depending on which of the regions 41 to 43 of the first wind receiving portion 40 the position of the widened end portion 52 of the second wind receiving portion 50 belongs.
At this time, since the reflection portion 55 is formed on the lower surface of the widened end portion 52, the reflected image of each of the regions 41 to 43 to which the widened end portion 52 belongs is reflected downward, and the wind state detection Even when the vessel 10 is at a high place, the current wind speed region can be easily confirmed visually from below.

  Further, when the support member 30 is rotated around the vertical vertical axis by the first wind receiving portion 40, the alarm portion 60 has its longitudinal direction parallel to the wind direction and the opening 62 faces the windward side. The wind enters from the opening 62. As a result, the airflow becomes a free jet in the nozzle portion 63 and is blown into the gap between the wind passage plates 65 and 65, and an alarm sound including an audible sound is generated when the wind speed reaches the high speed range.

As described above, in the wind condition detector 10, the first wind receiving portion 40 is in a state along the wind direction, and the second wind receiving portion 50 has an inclination angle corresponding to the wind speed. Can be easily recognized.
Further, the first wind receiving portion 40 also functions as a wind speed display portion. In particular, since the regions 41 to 43 are color-coded, any of the regions 41 to 43 in which the second wind receiving portion 50 indicates the wind speed region. Can be easily recognized visually.
Moreover, since the 2nd wind receiving part 50 has the reflection parts 55 and 55 in the lower surface of the wide end part 52, the reflected image of any area | regions 41-43 to which the 2nd wind receiving part 50 belongs reflects below. Therefore, the current wind speed region can be easily recognized from below.

Further, the first wind receiving portion 40 has a flat plate shape and is fixedly mounted on the support member 30 so as to be parallel to the rotation center line of the support member 30 and on the same plane. The receiving part 40 receives the wind, becomes parallel to the wind direction, and moves to the leeward side with respect to the support member. That is, it becomes possible to recognize the wind direction from an easier configuration.
Furthermore, since the first wind receiving portion 40 has areas 41 to 43 indicating the wind speed region displayed on the flat plate surface and functions as a wind speed display portion, the configuration of the wind state detector 10 is simplified, and the number of parts is reduced. Can be reduced.

Furthermore, since the areas 41 to 43 indicating the wind speed area displayed on the first wind receiver 40 indicate the appropriate or inappropriate wind speed area of the action performed in response to wind such as work at a high place, for example. From the inclination angle of the second wind receiving portion 50, it is possible to objectively determine whether or not the work is appropriate without depending on the experience of the worker.
Moreover, since the several wind speed area is displayed on the flat plate surface of the 1st wind-receiving part 40 by the several area | regions 41-43 by which the color divided | segmented into the fan shape differs, the present wind speed is which wind speed area | region. It can be confirmed even from a distance and more reliably.

Further, the first wind receiving portion 40 functioning as a wind speed display portion has a fan-like flat plate shape, and the second wind receiving portion 50 has a slit portion 54 into which the first wind receiving portion 40 is inserted on the widened end 52 side. Therefore, the second wind receiving portion 50 can be disposed in a state of being closer to the flat plate surface of the first wind receiving portion 40, and the second wind receiving portion 50 indicates any wind speed range. It becomes possible to recognize more accurately whether it belongs to these areas 41-43.
In addition, since the first wind receiving portion 40 is inserted into the slit portion 54 of the second wind receiving portion 50, the position of the second wind receiving portion 50 is determined from both sides of the first wind receiving portion 40. The wind speed can be recognized from a wider range.

  Moreover, since the 2nd wind receiving part 50 is a shape which has the blade | wing which has a predetermined opening angle on both sides of the slit part 54, it becomes possible to detect a wind speed with appropriate sensitivity.

Moreover, since the wind state detector 10 has the alarm part 60 which emits an alarm sound when the wind of the predetermined wind speed or more is received, the present wind speed is not limited only to vision, but the present wind speed is also in a predetermined wind speed range. Can be recognized. Therefore, even when the wind state detector 10 is not viewed, it is possible to notify that the predetermined wind speed range has been reached.
In addition, the alarm unit 60 includes wind passage plates 65 and 65 as wind passage members that emit an alarm sound when wind exceeds a predetermined wind speed. Therefore, the alarm unit 60 can be easily alerted by adjusting the dimensions of the installation positions of the wind passage plates 65 and 65. The frequency of the sound can be changed.
Moreover, since the alarm unit 60 is fixedly mounted on the support member 30, the alarm unit 60 can be rotated according to the wind direction, and can always be maintained in a direction in which an alarm sound can be generated. Regardless, it is possible to generate an alarm sound when a predetermined wind speed range is reached.
The alarm unit 60 is not limited to the support member 30 and may be fixedly mounted on the first wind receiving unit 40.
