Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings, but not as any limitation of the invention.
Support arm and the method for water nozzle dual regulation is realized, as shown in Figure 1 by a power shaft.The power shaft of the method is connected with output shaft through clutch shaft；Clutch shaft is cased with an eccentric shaft, between eccentric shaft and clutch shaft, uses not rounded axis hole to be slidably connected；When instrument is in decentralization process, before output shaft does not contacts with down-hole water nozzle, clutch shaft makes the non-circular hole on eccentric shaft of the non-circular shaft on clutch shaft be combined under the effect of preloading spring, and power shaft drives eccentric shaft to rotate through clutch shaft, controls support arm by eccentric shaft and opens or shrink；Instrument continues to transfer, after output shaft bottom contacts with water nozzle, under the effect of instrument deadweight, water nozzle promotes clutch shaft to overcome the active force upward sliding of preloading spring by output shaft, make clutch shaft depart from eccentric shaft, be controlled regulating to water nozzle by output shaft.Eccentric shaft is provided with stopper slot and stop screw, and stop screw is spun on housing, and the termination of stop screw withstands in stopper slot；Control eccentric shaft by stopper slot and stop screw to rotate in the range of 180 degree；The cylindrical of eccentric shaft contacts with the breach on support arm, and support arm through bearing pin and housing hinge, rotates counterclockwise when eccentric shaft high-end contacts with breach and overcomes the active force of tension spring to be contracted in housing；When eccentric shaft rotation turnback makes the low side of eccentric shaft contact with breach, support arm drives support arm to turn clockwise under the effect of tension spring and is flared out；To realize controlling the purpose that support arm opens or shrinks.Stopper slot and stop screw limit eccentric shaft and move axially；After output shaft bottom contacts with water nozzle, under the effect of instrument deadweight, water nozzle promotes clutch shaft to overcome the active force upward sliding of preloading spring by output shaft, can not move upwardly together with clutch shaft owing to stopper slot and stop screw limit eccentric shaft, clutch shaft is made to depart from eccentric shaft, the now rotation of power shaft can not drive eccentric shaft to rotate, and can only drive output shaft that water nozzle is controlled regulation；Realize the independent control to water nozzle.
The device constituted by preceding method, as it is shown in figure 1, include housing 1, housing 1 is provided with support arm 2, and support arm 2 is hinged with housing 1 through bearing pin 3, is provided with tension spring 4 inside support arm 2；Being provided with power shaft 5 in housing 1, power shaft 5 is connected with clutch shaft 6 and output shaft 7 successively；Clutch shaft 6 is externally provided with eccentric shaft 8.Eccentric shaft 8 is connected with clutch shaft 6 clutch；The cylindrical of eccentric shaft 8 contacts connection with the breach 9 on support arm 2.Eccentric shaft 8 is connected with clutch shaft 6 clutch: eccentric shaft 8 one end is provided with non-circular hole 10, and clutch shaft 6 is provided with non-circular shaft 11；It is bonding state that non-circular shaft 11 is positioned at non-circular hole 10, and non-circular shaft 11 is released state outside being positioned at non-circular hole 10.Eccentric shaft 8 is divided into two sections, and epimere is main cylinder, and hypomere is eccentric cylinder；Described non-circular hole 10 is located at main cylindrical tip.Non-circular hole 10 is delthyrium, four square holes, polygonal hole, elliptical aperture or keyhole, Axis Tripod, square axis, polygon shaft, elliptical shaft or the key axle that described non-circular shaft 11 right and wrong circular hole 10 is supporting.The main cylinder of eccentric shaft 8 is provided with stopper slot 12, and stopper slot 12 is the 180 degree of cannelures being circumferentially provided with.The housing 1 of stopper slot 12 correspondence position is provided with stop screw 13, and stop screw 13 termination is positioned at stopper slot 12.Clutch shaft 6 top is cased with preloading spring 14.
The work process of the present invention and principle
When being embodied as, power shaft 5 and clutch shaft 6, clutch shaft 6 and eccentric shaft 8, all use four directions shaft hole matching transmission between eccentric shaft 8 and clutch shaft 6.When power shaft 5 rotates, driving clutch shaft 6 to rotate, clutch shaft 6 drives eccentric shaft 8 to rotate, and eccentric shaft 8 is forwarded to low spot by high point.Support arm 2 ejects, and eccentric shaft 8 upper shed groove is circumference 180 °, and now stop screw 13 is spacing, and motor rotation blockage stops.Realize ejector arm ejection function.The most only need to invert motor can carry out receiving arm operation.After water collecting nozzle, owing to instrument gravity makes to push up on water nozzle output shaft 7, output shaft 7 pushes clutch shaft 6 and departs from eccentric shaft 8, and now motor can be rotated further, and drives output shaft 7 to rotate, it is achieved water nozzle regulatory function.After regulation completes, on carry instrument, water nozzle no longer upper top output shaft 7, motor is rotated further, and the non-circular shaft 11 on clutch shaft 6, under the effect of preloading spring 14, can return in the non-circular hole 10 of eccentric shaft 8, now clutch shaft 6 drives eccentric shaft 8 to rotate together, but now stop screw 13 is in limit restraining position, motor rotation blockage stops, and reversion motor can realize receiving arm function.
