Abstract
The invention discloses a method and a device for improving butting reliability of an underground flow measuring and adjusting instrument. An adjusting arm component on the underground flow measuring and adjusting instrument opens outwards under the effect of a tension torsion spring. The opening position of the adjusting arm component is limited through a positioning step when the adjusting arm component is butted with a water nozzle adjusting mechanism. When the adjusting arm component is at a butted position, one end of a pull rod which is connected with the adjusting arm component is in a free state to prevent impact force produced when the underground flow measuring and regulating instrument is butted with the water nozzle adjusting mechanism from being transferred to parts behind the pull rod. Since the transfer path of the impact force is cut off when one end of the pull rod is in the free state, the impact force is prevented from damaging the parts behind the pull rod, the service life of the instrument is prolonged and the measuring and adjusting reliability is improved.

The specific embodiment
are done further detailed description below in conjunction with accompanying drawing and embodiment to the present invention, but not as to any restriction of the present invention.
embodiments of the invention: as shown in Figure 1; When embodiment of the present invention a kind of improves the method for the reliable butt joint of downhole flow measurement and adjustment instrument; Regulating arm assembly 7 on its downhole flow measurement and adjustment instrument outwards opens under the effect of tension force torsion spring 12, and this method is the deployed position when limiting regulating arm assembly 7 and dock with water nozzle governor motion 15 through positioning step 8; When making regulating arm assembly 7 be in docking location, pull bar 1 other end that is connected with regulating arm assembly 7 is in free state; Impact force is passed to each parts after the pull bar 1 when preventing the downhole flow measurement and adjustment instrument docked with water nozzle governor motion 15.Described free state is the centre position that the sliding pin 9 on the transmission component 6 is positioned at the waist shape chute 11 on the pull bar 1; Impact force when regulating arm assembly 7 can't be docked regulating arm assembly 7 with water nozzle governor motion 15 passes to transmission component 6.The centre position that said sliding pin 9 is positioned at waist shape chute 11 is when regulating arm assembly 7 is positioned that a little 8 location can not continue to open; The waist shape stopper slot 3 that spacer pin 5 on the transmission component 6 is not conditioned on the support tube 2 is spacing; Still can promote transmission component 6 and move, make the sliding pin 9 on the transmission component 6 continue to move to the centre position at the waist shape chute 11 of pull bar 1 as straight line.
A kind of device that improves the reliable butt joint of downhole flow measurement and adjustment instrument that
are used for the inventive method does; The structural representation of this device is as shown in Figure 1; Comprise regulating arm assembly 7; Regulating arm assembly 7 is hinged with adjustable support tube 2, and regulating arm assembly 7 or adjustable support tube 2 are provided with positioning step 8, are provided with tension force torsion spring 12 between regulating arm assembly 7 and the adjustable support tube 2; Regulating arm assembly 7 flexibly connects through pull bar 1 and transmission component 6.Said pull bar 1 one ends are hinged through swivel pin 16 and regulating arm assembly 7, and pull bar 1 other end is provided with waist shape chute 11, and waist shape chute 11 is slide hinged with the sliding pin 9 on the transmission component 6.Said transmission component 6 is positioned at adjustable support tube 2, and transmission component 6 is provided with spacer pin 5, and adjustable support tube 2 is provided with waist shape stopper slot 3, and spacer pin 5 is slidingly connected with waist shape stopper slot 3.Said transmission component 6 is provided with screwed hole, and screwed hole is threaded with transmission external screw thread 4, and transmission external screw thread 4 is connected with motor 13 through shaft coupling 14.
The course of work of the present invention and principle are explained as follows:
state shown in Figure 1 is the sketch map that regulating arm assembly 7 is in open mode.Instrument docks success status with water nozzle governor motion 15; Regulating arm assembly 7 couples together through pull bar 1 with transmission component 6 one ends; Pull bar 1 is waist shape chutes 11 with transmission component 6 connecting portions; Guarantee that regulating arm assembly 7 does not need motor 13 to drive and only relies on the effect of tension force torsion spring 12 to open, and run at regulating arm assembly 7 under edge or the effect of injection well downhole flow regulator 10 and can easily regain in external force; Spacer pin 5 is installed on the transmission component 6 through the waist shape stopper slot 3 on the adjustable support tube 2 under transmission component 6 mounted situation; The other end of transmission component 6 is trapezoidal internal threads, is connected with the trapezoidal thread of transmission external screw thread 4; 4 rotations of transmission external screw thread under the effect of spacer pin 5, drive transmission component 6 and do rectilinear motion, under the effect of pull bar 1, drive whole regulating arm assembly 7 and realize draw-in and draw-off function simultaneously.
prior art is not set a step 8, and positioning step 8 can be located on the regulating arm assembly 7, also can be located on the adjustable support tube 2.Regulating arm assembly 7 stops when spacer pin 5 moves to the top of waist shape stopper slot 3 under the drive of transmission component 6, transmission component 6 stop motions, and regulating arm assembly 7 just can stop to open; When this situation caused regulating arm assembly 7 with the butt joint of water nozzle governor motion, pull bar 1 all can be stressed with transmission component 6, causes pull bar 1 and transmission component 6 distortion, in follow-up use, brings problem.
the present invention has increased positioning step 8 after improving, and makes that regulating arm assembly 7 can not continue to open after running into positioning step 8; The size of waist shape stopper slot 3 upwards prolongs; Under the situation that assurance regulating arm assembly 7 does not continue to open after running into positioning step 8; Transmission component 6 can continue to do rectilinear motion; The swivel pin 16 of cylinder lever connecting rod 1 and transmission component 6 can move in the waist shape chute 11 of pull bar 1, and the upper surface of waist shape stopper slot 3 contacts on the spacer pin on the transmission component 63 and adjustable support tube 2, and pull bar 1 and transmission component 6 have had certain clearance on the direction of pull of pull bar 1; Under this situation, when regulating arm assembly 7 docked with water nozzle governor motion 15, pull bar 1 can be not stressed with transmission component 6, can not be damaged, and advocates will concentrate on the straight pin of positioning step 8 and secured adjusted arm component 7.The intensity of positioning step 8 and straight pin is higher, not fragile.After the present invention improved docking calculation, through field trial, the reliability of instrument was greatly improved.
