Embodiment
As Fig. 1, shown in 2: it comprises two fasteners that can fasten mutually 11, fastener is an arc, two fasteners fasten the integral body that the back forms, the integral central that forms be one with wind transducer main shaft outline corresponding in profile, when two fasteners fasten, fastener is fixed on the main shaft of wind transducer, two fastener upper edges respectively are provided with a positioning seat 12 that is used for fixing the wind transducer rotating shaft, like this when attachment fastener, also can make the rotating shaft of wind transducer no longer rotated by the rubber strip friction, sidewall or top and bottom at fastener are provided with azimuth scale 13, azimuth scale is used for detecting the rotational angle of wind transducer, and the junction of two fasteners is provided with the fixture that can fix when two fasteners are fastened, can make things convenient for fastener to fix by fixture is set, need not artificial support, also can be fixed on the main shaft.
Because fastener is two, there are two places junction after two fasteners fasten, the fastener here also can be for a plurality of, its junction also can be for a plurality of, and still a plurality of operations are comparatively loaded down with trivial details, and general two fasteners are the most convenient, described fixture is to be respectively snap close 21 or the snap close for being arranged on the link axle 22 of junction, a place and being arranged on another junction, place that is arranged on junction, two places, when two snap closes were set, after fastener fastened, two snap closes are locked to get final product; When a snap close is only arranged, when another junction was the link axle, directly single snap close being locked got final product.Fixture can also adopt other immobilization materials to fix, and is wherein convenient with snap close, is priority scheme so the utility model adopts snap close.
Positioning seat comprise cylinder 31 and arc embrace the folder 32, cylinder is fixed on the fastener, the upper end of cylinder is provided with arc and embraces folder, the inboard that arc is embraced folder is provided with increases 4 of friction force rubber strip 33 or rubber blanket, be provided with a positioning seat on two fasteners separately, and rotational symmetry in the interior profile of two positioning seats when fastening about fastener.Positioning seat mainly is the rotating shaft that is used for locating wind transducer, does not allow its random rotation, and the rubber strip friction makes things convenient for the user to regulate.
As shown in Figure 6: embrace also to be provided with on the folder at arc and run through the screw 34 that arc is embraced the folder sidewall, screw is oriented and points to the direction that arc is embraced the grip hold arc degree center of circle.Wind transducer rotating shaft for fear of the part model is too little, so increased screw, by DRIVE SCREWS in screw the rotating shaft of wind transducer is fixed.
As shown in Figure 5: the last lower edge of two fasteners and the intersection of side form the inclined-plane through chamfered, and described azimuth scale is arranged on the inclined-plane; Can be user-friendly for like this and observe calibration.
Described azimuth scale is 360 ° of annular azimuth scales, is respectively equipped with the sign of " E " " W " " S " " N " on the azimuth scale, and scale is accurate to 2.5 ° at present.
Concrete using method is as follows,
Shown in Fig. 3,4: generally speaking, wind transducer only exteriorly mainly comprises main shaft 41, rotating shaft 42, weathervane 45, on main shaft, be provided with location scale 43, this has calibrated scale 44 in rotating shaft, location scale and calibrated scale operated by rotary motion are at the boundary of main shaft and rotating shaft, the location scale marker has fixing direction (being generally N), when installing, also is the north of the direction of N being aimed at geographic orientation.Wind transducer is connected with terminal.
When using, the sign in north on the utility model azimuth scale is alignd with the sign of location scale, preferably the upper surface of fastener can with the boundary of main shaft and rotating shaft at grade, like this in rotating shaft, numerical value is also the most approaching on calibrated scale and the azimuth scale, after the alignment, just fastener can be fastened, afterwards snap close is buckled, the utility model just is fixed on the wind transducer like this, and the rotating shaft seat that also is positioned is fixing, can be because of wind-force deflection, at this moment, by artificial adjustment rotating shaft, make the calibrated scale in the rotating shaft rest on azimuth scale respectively, 0 degree (direction of N), 45 degree, 90 degree, 135,180 degree (being the direction of S), 225 degree, 270 degree, 315 degree, the residence time is about one minute (because of time of computer image data is 1 minute), uses the intercom count off, after calibration is finished, can pull down the utility model, the corresponding data contrast that the scope scale of above-mentioned stop and computer are gathered, error all is no more than 5 degree, illustrate that wind transducer does not damage, can continue to use, otherwise then explanation needs to replace wind transducer.
