Abstract
The utility model provides a tilting prevention device for a water level wheel blocking sheet of a steel belt type water level gauge. The tilting prevention device comprises a tilting prevention pin with threads and a positioning threaded hole, wherein the positioning threaded hole is formed in the joint of the water level wheel blocking sheet of the steel belt type water level gauge and the tail end of the rotating shaft; an angle Alpha which is larger than or equal to 30 degrees and smaller than or equal to 90 degrees is formed between the positioning threaded hole and a rotating shaft tail of the steel belt type water level gauge; and threads of the tilting prevention pin and threads of the positioning threaded hole are matched. According to the technical scheme, the disadvantage that the water level wheel blocking sheet of the water level gauge fixes the water level wheel in a single direction is made up; the tilting prevention device is added and matched with the water level wheel blocking sheet, the water level wheel is fixed three-dimensionally and comprehensively, back spinning of the water level wheel blocking sheet is avoided, and the accuracy of collected data is guaranteed.
Description
Technical field
The utility model relates to the hydropower field, relates in particular to a kind of steel band type water-level gauge water level wheel catch tilting prevention device.
Background technology
The steel band type water-level gauge is with float sensing water level, adopts the perforation stainless steel band to connect as suspension cable the mechanical type telemetering water level sensor that water level wheel drives the shaft-position encoder coding.The water level wheel catch is the water level wheel fastener, guarantees that water level wheel is passed to coded portion accurately by the corner of generation.The steel band type water-level gauge, for the variation of sensing natural water body water level, in water level logging system, is installed a float, as the water level sensing element.When SEA LEVEL VARIATION, float responds delicately SEA LEVEL VARIATION and does corresponding fluctuation campaign, the rectilinear motion of this fluctuation in stage is passed to water level wheel by suspension cable, make water level wheel produce circular motion, and exactly straight-line displacement amount is converted to corresponding angular displacement simultaneously.The water level wheel pivot is exactly the input shaft of shaft-position encoder, therefore, when water level wheel rotates, by shaft-position encoder, the water level analog quantity is converted to amount of digital information, to meet the needs of communication, processing, record and demonstration.Be applicable to the level measuring at rivers, lake, reservoir, river mouth, channel, ship lock, underground water and various hydraulic structures place.
The positions that water-level fluctuation is large, luffing is large, fluctuation time is short such as the steel band type water-level gauge that hydraulic power plant installs mainly is laid on dam, tail water; The frequent forward and reverse rotation of water level wheel, and the water level wheel catch is to design by longitudinal screw direction precession fastening means, affected by friction force can become flexible gradually, backspin appears, can't fastening water level wheel, cause water level wheel to skid, the corner that water level wheel produces can't be passed to coded portion accurately, water level wheel or the motionless phenomenon of water level wheel pivot even occur, cause the data that collect can't the accurate response SEA LEVEL VARIATION.
The utility model content
For addressing the above problem, the utility model provides a kind of steel band type water-level gauge water level wheel catch tilting prevention device, comprise threaded anti-down pin and positioning spiro pit, described positioning spiro pit is in the junction of steel band type water-level gauge water level wheel catch and turning axle afterbody, the angled α of turning axle tail of described positioning spiro pit and steel band type water-level gauge, 30≤α≤90 wherein, anti-down pin screw thread matches with the positioning spiro pit screw thread, preferably, α=60 °.
Further, described positioning spiro pit is through hole, and the afterbody of described anti-down pin passes from described positioning spiro pit.
Further, described anti-down pin is that screw bolt and nut connects.
Present design makes up water-level gauge water level wheel catch from the fixing deficiency of water level wheel of one direction, by installing this tilting prevention device additional, with the water level wheel catch, coordinates, and stereoscopic and omnibearing is water level wheel fixedly, stops the water level wheel catch and backspin occurs, has guaranteed the data accuracy gathered.

Embodiment
It is simple in structure that this utility model discloses a kind of steel band type water-level gauge water level wheel catch tilting prevention device, the execute-in-place simple and convenient, can effectively solve the water level wheel catch affected by friction force easily looseningly to cause water level wheel to skid, the problem of even reversing, the data that make water-level gauge collect are reacted SEA LEVEL VARIATION exactly, affected by fluctuation in stage, described device comprises anti-down pin (10) and positioning spiro pit (20), refer to Fig. 1 and Fig. 2, the junction car positioning spiro pit (20) of steel band type water-level gauge water level wheel catch (12) and turning axle (11) afterbody, the angled α of turning axle (11) of described positioning spiro pit (20) and steel band type water-level gauge, 30 °≤α≤90 ° wherein.
According to steel band type water-level gauge difference, the diameter difference of turning axle, screw in screw thread junction car positioning spiro pit at turning axle tail and water level wheel catch, and count example with WFY type water level: WFY type water-level gauge turning axle diameter 6mm, regioselective threaded hole diameter is 2mm.The positioning spiro pit angle of bevel is excessive, and the adjustable extent of anti-down pin cap and catch is less; Angle too small, can cause anti-down pin nuts can not contact with catch, do not have anti-down effect, and the positioning spiro pit oblique angle α=60 ° of take is optimum.
With the positioning threads bore dia accordingly car go out anti-down pin diameter, or the choice criteria bolt substitutes, and then at turning axle afterbody car with corresponding positioning spiro pit.Count example with WFY type water level: WFY type water-level gauge turning axle diameter 6mm, selecting anti-down pin bolt is M2 * 4.
For thering is the water-level gauge that tightens up screw, as the WFY type, utilize the adjustable energy saving that tightens up screw, can simplify the tilting prevention device setting, directly take vertical perforating to see Fig. 3 positioning spiro pit, or directly with standard bolt and nut, replace maintenance for convenience detach.Its operating process changes to: pine tightens up screw, and---water level runner catch screws in---anti-down pin bolt is fixed----tighten up screw to be fixed by nut.
Further, while on turning axle, positioning spiro pit being set, it is punched to open-work, use anti-down pin bolt column tail to contact even at the cost of one's life with water level runner catch, refer to Fig. 4, play anti-down effect.Its positioning spiro pit oblique angle should suitably strengthen, and generally should select 60 ° of left and right.
Present design makes up water-level gauge water level wheel catch from the fixing deficiency of water level wheel of one direction, by installing this tilting prevention device additional, with the water level wheel catch, coordinates, and stereoscopic and omnibearing is water level wheel fixedly, stops the water level wheel catch and backspin occurs, has guaranteed the data accuracy gathered.
Above embodiment is only unrestricted in order to the technical solution of the utility model to be described, all any modifications of doing in spirit of the present utility model and principle, is equal to and replaces or improvement etc., all should be included in protection domain of the present utility model.
