specific Embodiment approach 1

[0008] Specific implementation mode one: combine Figure 1~4 Describe this embodiment. The cordless docking device of the water injection well measuring and adjusting instrument described in this embodiment includes a base body 1, a motor assembly 6, a docking arm pop-up retracting mechanism, and a docking arm. The cavity 1-1 of the retracting mechanism and the docking arm, the motor assembly 6 drives the movement of the pop-up retracting mechanism of the docking arm to realize the pop-up and retracting actions of the docking arm; the pop-up retracting mechanism of the docking arm includes a lead screw 8, a nut 9, a push rod 13. Slider 15, push rod 18, connecting rod 19, small torsion spring 20 and coil spring 22; the docking arm includes upper torsion spring 3, pop-up arm 5, lower torsion spring 14 and measuring and adjusting motor sleeve 17; motor assembly 6 is located on the upper part of the cavity 1-1 and fixed on the side wall of the cavity 1-1, the lead screw 8 is locat...

Abstract

The invention discloses a wire rope-free jointing device of a water injection well measurement adjuster, which relates to the jointing device of the water injection well measurement adjuster and aims to solve the problem that a jointing mechanism of a wire rope measurement adjuster has the disadvantages of difficult machining, quick-wearing wire ropes, easy interference among the wire ropes, and the like. A lower end face of a nut is connected with the upper end of a push rod; the push rod is positioned below a slide block; the upper end of the push rod is fixedly connected with the lower endface of the slide block, while a lower end is connected with the upper end of a spiral spring; the lower end of the spiral spring is connected with the upper end face of an accommodating cavity of a substrate; one end of a connecting rod is hinged with the corresponding outer sidewall of the push rod, and a small torsional spring is arranged at a hinging joint; the other end of the connecting rodis hinged with the outer sidewall of a measurement adjustment motor sleeve; the upper end of the measurement adjustment motor sleeve is hinged with one end of a popup arm, and a lower torsional spring is arranged at the hinging joint; and the other end of the popup arm is hinged with the sidewall of the upper end of the accommodating cavity, and an upper torsional spring is arranged at the hinging joint. The wire rope-free jointing device realizes the popup and withdrawal of a jointing arm of the water injection well measurement adjuster under the condition of not using the wire ropes.

Description

technical field [0001] The invention relates to a docking device for a water injection well measuring and adjusting instrument. Background technique [0002] At present, the measuring and adjusting instruments for flow control of water injection wells in oil fields are mainly single-motor with rope structure, and the ejection and retraction of the docking arm are realized by using the wire rope. However, due to the narrow space of the instrument itself, the steel wire rope should not be too thick. Therefore, when the docking mechanism moves to the limit position or encounters a jam, the steel wire rope is easily broken, and maintenance is very troublesome; the steel wire rope is easy to interfere with other mechanisms. In addition, because the steel wire rope can only When the tension is generated, the docking mechanism can only rely on the torsion spring when it pops up, which requires high performance of the torsion spring, which increases the difficulty and cost of proces...
