Abstract
The utility model discloses a wind direction indicator, which comprises rings, a support shaft, a shaft sleeve and a wind bag. The wind bag is in a shape of a bag and sewed on a ring (1) and a ring (2). The ring (1) and the ring (2) are respectively placed on the front and the back, the rings are connected through a support rod (3) and supported through the support shaft (5) which is installed in the shaft sleeve (6) and correspondingly fixed with the shaft sleeve (6). The wind direction indicator can observe wind direction in remote accurately and provide wind direction indication for land and sea oil well drilling process and agricultural and industrial production. The wind direction indicator is simple in structure, small in wind bag rotating resistance, flexible in rotating and timely and accurate in wind direction indication.
Description
Technical field
The utility model 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 purpose of the utility model designs a kind of wind direction indicator exactly.The utility model 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 utility model can be observed 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 utility model 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 the structural representation of the utility model.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.
The principle of work of wind direction indicator the utility model 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.
