Abstract
The utility model discloses a kind of weathervane, comprise mark post, horizon bar, bar head, empennage, balance element.Mark post and horizon bar intersection are provided with precision bearing, the front end of horizon bar is provided with arrow shaped bar head, the rear end of horizon bar is provided with two trapezoidal shapes, size, completely the same and upper and lower, the symmetrical empennage be connected on horizon bar of weight, and the angle between two empennages is 22 degree.Between the bar head and tail wing of horizon bar, be provided with balance element, described balance element is hollow type cylindrical shape, is movably fixed on horizon bar.Compared with prior art, structure is simple, and cost is low for the utility model, more importantly has higher sensitivity, accuracy and good stability.
Description
Technical field
The utility model relates to a kind of device identifying wind direction, be specifically related to a kind of structure simple, measure weathervane accurately.
Background technology
Weathervane is in order to indicate the device of wind direction in various instrument for wind measurement.Weathervane is extensively with at places such as meteorological station, airport, boats and ships petroleum drilling raised platforms around a well.Have three to the basic demand of weathervane, the first is sensitive, and namely weathervane also can reflect soon when wind speed is less or change of the wind is little; It two is to stablize, and namely weathervane should do bobbing as little as possible; It three is want accurately, namely reduces the friction in axle portion, reduces the weight of weathervane, reduce the radius of gyration, increase wind area, improve the shape of weathercock.Weathervane kind disclosed in prior art and style more, but it is possible to meet the little of above-mentioned three basic demands.Therefore, weathervane need further improvement.
Summary of the invention
The purpose of this utility model is the deficiency existed for prior art, provides one to take into account sensitive, stable and accurate three kinds of characteristics, and the weathervane that structure is simple, cost is low.
For achieving the above object, the utility model adopts following technical scheme.
Weathervane of the present utility model comprises mark post, horizon bar, bar head, empennage, balance element.Described mark post and horizon bar intersection are provided with precision bearing, the front end of horizon bar is provided with arrow shaped bar head, the rear end of horizon bar is provided with two trapezoidal shapes, size, completely the same and upper and lower, the symmetrical empennage be connected on horizon bar of weight, and the angle between two empennages is 22 degree.Between the bar head and tail wing of horizon bar, be provided with balance element, described balance element is hollow type cylindrical shape, is movably fixed on horizon bar.
During installation, first at rational position fixed pole, then by the fixed connecting rod head and tail wing, be flexibly connected the horizon bar of balance element and be arranged on mark post, when the position finally adjusting balance element is to horizon bar level, balance element and balance element are fixed.
The beneficial effects of the utility model
(1) the utility model is provided with precision bearing at mark post and horizon bar intersection, horizontality is in by balance element adjustment horizon bar, the more important thing is to be provided with in the rear end of horizon bar two larger in trapezoidal shape, angle is the empennage of 22 degree, increase the blast in vertical direction, therefore, also can reflect soon during less or wind direction generation minor alteration at wind speed, there is higher sensitivity and accuracy; (2) due to the utility model be provided with two trapezoidal shapes in the rear end of horizon bar, angle is the symmetrical empennage of 22 degree, due to the effect of angle, increase the resistance that weathervane swings, reduce the free-wheel of weathervane, therefore there is good stability.(3) the utility model structure is simple, and cost is low.
Accompanying drawing explanation
Fig. 1 is structural front view of the present utility model.
Fig. 2 is structure vertical view of the present utility model.
In figure: 1, mark post, 2, horizon bar, 3, bar head, 4, empennage, 5, balance element, 6, angle.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, weathervane of the present utility model comprises mark post 1, horizon bar 2, bar head 3, empennage 4, balance element 5.Described mark post 1 and horizon bar 2 intersection are provided with precision bearing, and the front end of horizon bar 2 is provided with arrow shaped bar head 3, horizon bar 2 rear end is provided with two trapezoidal shapes, size, weight is completely the same and symmetry is connected to the empennage 4 on horizon bar 2.Between the bar head 3 and empennage 4 of horizon bar 2, be provided with balance element 5, balance element is hollow type cylindrical shape, is movably fixed on horizon bar 2.
As shown in Figure 2, the angle 6 between two trapezoidal shape empennages 4 of horizon bar 2 rear end of the utility model weathervane is 22 degree.
Claims (2)
1. a weathervane, is characterized in that, weathervane comprises mark post (1), horizon bar (2), bar head (3), empennage (4), balance element (5); Described mark post (1) is provided with precision bearing with the intersection of horizon bar (2), the front end of horizon bar (2) is provided with arrow shaped bar head (3), the rear end of horizon bar (2) is provided with two trapezoidal shapes, size, completely the same and upper and lower, the symmetrical empennage (4) be connected on horizon bar (2) of weight, balance element (5) is provided with between the bar head (3) and empennage (4) of horizon bar (2), balance element (5) is hollow type cylindrical shape, is movably fixed on horizon bar (2).
