Description
Technical field
The utility model relates to a kind of shift transmission device, relates in particular to a kind of guide vanes of water turbine servomotor shift transmission device that can realize linear measurement.
Background technology
In hydroelectric control procedure, the aperture feedback signal that needs usually to gather guide vanes of water turbine is exerted oneself with control rotational speed of water turbine and genset.Existing potentiometer stay-supported guide vanes of water turbine servomotor shift transmission device is a multiturn potentiometer to be inserted in the opening cylindrical shell at box middle part, an end its shell is located, the potentiometer upper mandrel then penetrates in the hypomere endoporus of a clockwork spring box with the holding screw location, with the spring case positive and reverse return then realize that the guide vane servomotor piston displacement becomes the function of sending.Spring case be rotated in the forward that to be the wire rope that wound in advance by its outer garden by end box cover one aperture pass links to each other with the guide vanes of water turbine servomotor and move traction with its piston and realize; When clockwork spring box moves with backguy and when rotating, clockwork spring is corresponding to screw accumulation of energy; When the guide vanes of water turbine servomotor oppositely moves, make backguy under the effect of clockwork spring power, furl on the outer garden of spring case with the spring case reverse rotation, the clockwork spring box of this positive and negative rotation transfers the electric signal of output transform with the multiturn potentiometer axle positive and reverse return in its hypomere endoporus.
But the displacement of guide vanes of water turbine servomotor piston is with the continuous random variation of practical operation situation in electrical network and power station, and is sometimes fast and sometimes slow, short during duration.And the inboard of the Wiinding cartridge of said structure (being made up of garden in the outer garden of above-mentioned clockwork spring box and the lid) be the outer garden of spring case is a shiny surface of not establishing the coiling gathering sill.This certainly will lap wound occur when furling wire rope or crossing is irregular, is difficult to realize linear measurement.What simultaneously the ring cavity of Wiinding cartridge also have to respective design is more roomy, the card line problem when this is prone to pulling this device of examination quick loose wire rope again, though this device of removable processing, the refitting process is very cumbersome.
Summary of the invention
Can not realize the defective of linear measurement and liable to block wire in order to improve existing guide vanes of water turbine shift transmission device, the utility model provides a kind of guide vanes of water turbine servomotor shift transmission device with helicla flute coiling chamber, this device can not only effectively be realized linear measurement, and installs not liable to block wire.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of guide vanes of water turbine servomotor shift transmission device, comprise loam cake, clockwork spring, clockwork spring box, outer cover, potentiometer, wire rope and end box, multiturn potentiometer, the clockwork spring box that to pack in the end box are connected according to the order of sequence with loam cake, are provided with helicla flute coiling chamber in the outer garden of clockwork spring box hypomere and the outer cover of multiturn potentiometer upper mandrel between the garden.
The thickness car system and the corresponding to wire rope helicla flute of potentiometer rotating cycle of haulage cable press in the outer garden of the hypomere of clockwork spring box, and outer garden has in the outer cover that spiral fluted clockwork spring box hypomere inserts the multiturn potentiometer upper mandrel and constitutes the helicla flute chamber that winds the line.One holding screw that protrudes is arranged on the center hole wall of described clockwork spring box hypomere, make it be inserted in the potentiometer upper mandrel that is milled with the plane after, under the traction of wire rope, can be with the potentiometer axle to rotate.The shell of potentiometer then inserts in the end box intermediate openings cylindrical shell and is fixed.Job-hopping occurs for preventing that wire rope from twining fast, be provided with the outer cover of potentiometer axle, the outer cover bottom center is shaped on internal thread, and it matches with swivel nut on the multiturn potentiometer axle.The inwall of described outer cover is little than wirerope diameter with above-mentioned clockwork spring box hypomere Wai Yuan gap slightly, and haulage cable then passes with guide vanes of water turbine servomotor piston element from the perforate of box side, the end and links to each other.
Like this, wire rope produces the wire rope that twines that is arranged in parallel in the helicla flute coiling chamber under the traction of guide vanes of water turbine servomotor piston according to the order of sequence.The potentiometer axle promptly clockwork spring box with rope belt and is rotated and corresponding rotation, makes the output respective change of original electric signal, and clockwork spring rotates with spring case and tightens energy storage simultaneously; When guide vanes of water turbine servomotor piston reverses direction moved, under the effect of the clockwork spring energy of crispaturaing, the spring case backward rotation made the corresponding change of electric signal of original output.By the wire rope that is arranged in parallel and twines that helicla flute coiling chamber guarantees, the guide vanes of water turbine servomotor stroke that characterizes that whenever turns around is identical, so this change send device can be able to the purpose of linear measurement.
The utility model makes guide vanes of water turbine servomotor displacement energy effectively realize linear measurement, liable to block wire not, and the dress that disintegrates is multiple comparatively simple.
Description of drawings
Accompanying drawing 1 structural representation of the present utility model
Embodiment
Further specify below in conjunction with 1 pair of the utility model of accompanying drawing.
In accompanying drawing 1 illustrated example, outer cover 4 screws back set nut 7 lockings with the swivel nut of potentiometer 5 axle bottoms.Wire rope 12 terminations at clockwork spring box 3 hypomeres that install clockwork spring 2 and holding screw 9 are passed by the wire hole that covers on 4 walls down, and simultaneously potentiometer 5 upper mandrel are inserted in the clockwork spring box 3 hypomere center pits, and the shell of rotational potentiometer 5 is to start bit; After haulage cable 12 terminations are passed by the sidewall wire hole of end box 6, potentiometer 5 is inserted in the opening cylindrical shell at box 6 middle parts, the end, insert in the center pit upper end bearing 8 of clockwork spring box 3 after the axle open slot 10 of loam cake 1 being embedded the back bending inner termination of clockwork springs 2, constitute the upper support point of clockwork spring box 3 rotations; Rotary upper cover 1 makes haulage cable 12 be involved in according to the order of sequence along helicla flute coiling chamber 11, changes up to potentiometer 5 upper mandrel and stops, and assembles with end box 6 after again loam cake 1 being continued to rotate the suitable pretightning force that forms clockwork spring 2.
With pulling this device of examination, to receive fast and restrict when blocking line once in a while, the processing dress that also must disintegrate certainly is multiple, but dress is comparatively simple again.After the disintegration, wire rope 12 total roots needn't be cut, it only needs fag end is drawn through above-mentioned potentiometer 5 axle outer covers 4 wire holes, pass the 6 side perforates of end box, after treating that loam cake 1 axle open slot, 10 embedding clockwork springs and head penetrate in the clockwork spring box 3 center pits upper end bearing 8, rotary upper cover 1, be with clockwork spring box 3 to rotate through clockwork spring 2, wire rope 12 is arranged in the helicla flute coiling chamber 11 according to the order of sequence, go to the dead point until potentiometer 5 axles of rotating with clockwork spring box, clockwork spring box 3 stalls, the spring converse rotating force appears in loam cake 1, this is the pretightning force of clockwork spring, and suitable clockwork spring pretightning force is the basis of wire rope 12 backguy flexibility and reliability, screws loam cake 1 and end box 6 again and is screwed.
