Abstract
The invention discloses a wind direction indicator which comprises circular rings, a support shaft, a shaft sleeve and a windsail, wherein the windsail is shaped as a bag and is sewn on the circular rings (1) and (2) which are respectively placed in front of and behind the windsail, the circular rings are connected together through a support rod (3) and are supported by the support shaft (5), and the support shaft (5) is arranged in the shaft sleeve (6) and is fixed relative to the shaft sleeve (6). The wind direction indicator can be used for observing the wind direction remotely and more accurately, and provides the wind direction indication for the petroleum drilling process in land and sea and the agriculture and industry production. The wind direction indicator has a simple structure and is little in rotation resistance of the windsail, thereby being flexible in rotation and timely and accurate in display of the wind direction.
Description
Technical field
The present invention relates to a kind of wind direction indicator of discerning wind direction.
Background technology
The indication device of measuring wind direction is often arranged on airport, boats and ships, petroleum well drilling derrick; Like radar, electronic weather platform, the mini weather station of palm-type etc.; They mainly are through electronic installation measuring wind and wind direction, can only be used for local control personnel and closely obtain related data, carry out the long-distance transmissions related data information again; Can not intuitively estimate wind direction at a distance; And estimate the circular hood of wind direction at a distance, and be mostly simple and easy circular hood, owing to adopt the directly fixing structure of wind sleeve of steel ring, wind plays difficulty of wind sleeve, and rotates dumbly, often block, thus the promptness and the accuracy of influence measurement wind direction.
Summary of the invention
The object of the invention designs a kind of wind direction indicator exactly.The present invention is achieved in that a kind of wind direction indicator, and it comprises annulus, back shaft, axle sleeve and circular hood, and circular hood is a pocket-like, and circular hood is made on annulus (1), annulus (2).Before and after described annulus (1) and (2) are placed on respectively, link together through support bar (3) between each annulus, annulus is supported by back shaft (5), and back shaft (5) is installed in the axle sleeve (6), with axle sleeve (6) relative fixed.The present invention can observe wind direction at a distance more exactly, in land, the extra large Process of Oil Well Drilling and industrial and agricultural production wind direction indication is provided.The present invention is simple in structure, and the circular hood rotary resistance is little, therefore rotates flexibly to show wind direction promptly and accurately.
Description of drawings
Fig. 1 is a structural representation of the present invention.Among the figure: 1-annulus, 2-annulus, 3-support bar, 5-back shaft, 6-axle sleeve.
Embodiment
With reference to accompanying drawing 1, a kind of wind direction indicator, it comprises annulus (1), annulus (2), circular hood and back shaft (5) composition, and circular hood is a pocket-like, and circular hood is made on annulus (1), annulus (2).Before and after described annulus (1) and (2) are placed on respectively, link together through support bar (3) between each annulus, annulus is supported by back shaft (5), and back shaft (5) is installed in the axle sleeve (6), with axle sleeve (6) relative fixed.
Wind direction indicator principle of work of the present invention is: when the wind time-out, wind gets into circular hood from annulus 1 inlet through annulus 2, because the circular hood afterbody goes out young; Wind meets obstructions; Circular hood is floated up, and at this moment circular hood will be with the box haul rotation in axle sleeve 6 together of annulus 1, annulus 2 and back shaft 5, and circular hood rests on the orientation consistent with wind direction at last; Make circular hood in time show the direction of wind; Owing to be sewed with circular reflecting strips on the circular hood, as long as light is arranged, even night circular hood also high-visible.At this moment, can in time know wind direction at aircraft or Drilling derrick people at a distance, to confirm taking which kind of measure to comply with wind direction.
Claims (3)
1. a wind direction indicator is characterized in that it comprises annulus (1), annulus (2), circular hood and back shaft axle (5) and axle sleeve (6) composition, and circular hood is a pocket-like, and circular hood is made on annulus (1), annulus (2).
2. a kind of wind direction indicator according to claim 1; Before and after it is characterized in that described annulus (1) and (2) are placed on respectively, link together through support bar (3) between each annulus, annulus is supported by back shaft (5); Back shaft (5) is installed in the axle sleeve (6), with axle sleeve (6) relative fixed.
3. a kind of wind direction indicator according to claim 1 is characterized in that being sewed with on the described circular hood circular reflecting strips.
