When the device is used, the diameter of the bottom ring is larger than that of the top ring, therefore, the support frame consisting of the bottom ring and the top ring is more stable, the top ring and the rotating ring sheet are respectively sleeved on the upper middle shaft and the lower middle shaft of the limiting ring, the middle shaft and the rotating ring sheet can be rotatably adjusted, the direction indication of the compass corresponds to the direction mark line on the rotating ring sheet, the wind direction can be conveniently confirmed subsequently, when wind blows on the device, pressure can be generated on the tail wing plate and the wind direction rod, the stress area of the tail wing plate is larger, the wind pressure is unbalanced, wind torque can be generated, the tail wing plate and the wind direction rod rotate around the bearing, when the wind direction rod points to the wind direction, the stress on the two sides of the tail wing plate is balanced, the wind direction rod can stably point to the position, the wind direction can be determined, the lower end of the indicating rod is.

The inner side of the indicating rod is fixedly connected with a semicircular annular rope buckle, and an alignment rope is fixed on the rope buckle. The counterpoint rope can blow along with the wind, can compare with the wind direction pole that stabilizes down, and the wind direction test is more accurate.

The both sides symmetry of spacing ring is fixed with the rotation handle, is fixed with anti-skidding vertical stripe on the outer wall of rotating ring piece. The compass is provided with a rotating handle and anti-skid vertical lines, so that the center shaft and the rotating ring piece can be conveniently rotated and adjusted, and the compass points to correspond to the direction mark lines.

The utility model discloses the beneficial effect who has is: the utility model has the advantages of reasonable design, regulation direction that can be convenient marks, and wind direction test that can be accurate is compared with the test, and the wind direction test is accurate, and convenience simple to use is worth using widely.

Detailed Description

The present invention will be described in detail below with reference to fig. 1 and 2.

As shown in fig. 1 and 2, the utility model comprises a support frame, a middle shaft 3, a limit ring 4, a rotating ring plate 5, a compass 7, a support rod 9, a tail wing plate 11, a wind direction rod 12, an indication rod 13 and a contraposition rope 8, wherein the support frame is composed of a bottom ring 1, a top ring 15 and a connecting rod 2, the radius of the top ring 15 is half of that of the bottom ring 1, the top ring 15 is positioned right above the

bottom ring

1, and 4 connecting rods 2 are uniformly connected between the bottom ring and the bottom ring, the middle part of the middle shaft 3 is fixedly sleeved with the limit ring 4, the top ring 15 is sleeved on the middle shaft 3 at the lower side of the limit ring 4, the rotating ring plate 5 is rotatably sleeved on the middle shaft 3 at the upper side of the limit ring 4, a direction mark 6 is arranged on the rotating ring plate 5, the support rod 9 is fixed at the center of the top surface of the middle shaft 3 by screw joint, the, a trapezoidal tail wing plate 11 is fixedly connected to one side of the bearing 10, a wind direction rod 12 is fixedly connected to the other side of the bearing 10, and an indication rod 13 perpendicular to the wind direction rod 12 is fixedly connected to the end portion of the wind direction rod 12. When the device is used, the diameter of the bottom ring 1 is larger than that of the top ring 15, so that the support frame consisting of the bottom ring 1 and the top ring 15 is more stable, the top ring 15 and the rotating ring piece 5 are respectively sleeved on the middle shaft 3 above and below the limiting ring 4, the middle shaft 3 and the rotating ring piece 5 can be rotatably adjusted, the direction indication of the compass 7 corresponds to the direction mark 6 on the rotating ring piece 5, the subsequent wind direction confirmation is convenient, when wind blows on the device, pressure can be generated on the tail wing plate 11 and the wind direction rod 12, because the stress area of the tail wing plate 11 is larger, the wind pressure is unbalanced, wind torque can be generated, the tail wing plate 11 and the wind direction rod 12 rotate around the bearing 10, when the wind direction rod 12 points to the wind blowing direction, the stress on two sides of the tail wing plate 11 is balanced, the wind direction rod 12 stably points to the position, the wind direction is determined, and the lower end of the indicating rod 13 is close to the direction, the use is simple and convenient.

A semicircular annular rope buckle 14 is fixedly connected to the inner side of the indicating rod 13, and an alignment rope 8 is fixed on the rope buckle 14. The alignment rope 8 can be blown along with wind, and can be compared with the wind direction rod 12 which is stabilized down, so that the wind direction test is more accurate.

The two sides of the limiting ring 4 are symmetrically fixed with rotating handles 16, and the outer wall of the rotating ring piece 5 is fixedly provided with anti-skidding vertical stripes. The rotary handle 16 and the anti-skid vertical lines are arranged, so that the center shaft 3 and the rotary ring piece 5 can be conveniently rotated and adjusted, and the compass 7 points to correspond to the direction mark line 6.

When the device is used, the middle shaft 3 and the rotating ring piece 5 are rotated, the direction indicated by the compass 7 corresponds to the direction mark 6 on the rotating ring piece 5, wind blows the device, then the direction of the direction mark 6 corresponding to the indicating rod 13 is confirmed to be the wind direction, and wind direction comparison can be carried out through the blowing wind direction of the aligning rope 8.
