The course of work of the present utility model and principle are as follows:
When using the utility model, should regulate from bottom to top, major function of the present utility model is to solve water yield regulatory function, be exactly in addition solved instrument can be from bottom to top the time smoothly by the water distributing core in the well, by after need seat when going into this grade water distribution fuse, the utility model but can not pass through this water distributing core, but seat goes into this water distributing core and begin test or regulate, and this point also is characteristics of the present utility model; Before the utility model gone into the well, Ying Renwei packed up instrument and locked, arrive assigned address after (be generally next stage water distributing core), environment is judged by dependence system self, thus the rotation of control motor flicks under the effect of spring force, at this moment just begins to regulate.
The water distributing core 1 of regulating of the present utility model is divided into core pipe 3 and following core pipe 4, on last core pipe 3, water nozzle is set, in last core pipe 3, be provided with control valve 6, control valve 6 is threaded with last core pipe 3, control valve 6 is provided with the driver slot of available instrument rotation, by rotating regulation valve 6 control valve is moved axially in last core pipe 3, when moving on the control valve 6, the part that shelters from water nozzle 5 with control valve 6 becomes big, and flow increases; When control valve 6 moved down, the part that shelters from water nozzle 5 with control valve 6 diminished, and flow reduces.
The down-hole adjustment means comprises the erection device 7, the measurement mechanism 8 that is used for measuring well downforce and flow that are connected with hoist cable 2, is used to control the control device 9 of motor 13 runnings and the adjusting device 10 that is used to regulate water distributing core 1 flow.Erection device 7, measurement mechanism 8 and control device 9 all can adopt existing.The utility model mainly is that adjusting device 10 is improved.Adjusting device 10 comprises pawl cover 6, and a pawl cover 6 is connected with measurement mechanism or adjusting device.During use, tying up erection device 7 with hoist cable 2, guide head 15 on the adjusting device 10 is put into water injection well from well head downwards, during water distributing core 1 in running into water injection well 28, the taper of guide head 15 heads can be played good guide effect, enter the hole of water distributing core 1, continue again to transferring, the lower link 26 of the actuating arm 20 on the adjusting device 10 can be against on the hole wall of water distributing core 1 at first, owing to be subjected to the action of gravity of down-hole adjustment means self, the hole wall extruding lower link 26 of water distributing core 1 inwardly shrinks, make and the hinged last connecting rod 27 of lower link 26 top upwards, because last connecting rod 27 is hinged with regulating sleeve 17, above connecting rod 27 also can head on the strength that regulating sleeve 17 overcomes stage clip and move up, the bulge loop 23 that is located at regulating sleeve 17 upper ends will prop up upwards top of pawl 21 by the driving breach 22 that is located on the pawl 21, because a pawl 21 is hinged on the pawl cover 19, so a pawl 21 can not move up, can only be to shrink in a pawl groove of fulcrum rotation on a pawl cover 19 with the bearing pin, pawl 21 on the pawl cover 19 is contracted to can be by the size of water distributing core, makes the adjusting device 10 can be with measurement mechanism or the adjusting device water distributing core 1 by above each layer downwards together.When arrival needed the water distributing core 1 of regulating course, seat can begin test or adjusting after going into water distributing core 1; At this moment actuating arm 20 ejects, and is stuck in the groove on the control valve 6, and starter motor 13 then, and motor 13 is being with control valve 6 rotations.By rotating regulation valve 6 control valve is moved axially in last core pipe 3, when moving on the control valve 6, the part that shelters from water nozzle 5 with control valve 6 becomes big, and flow increases; When control valve 6 moved down, the part that shelters from water nozzle 5 with control valve 6 diminished, and flow reduces.
The down-hole adjustment means is that water distributing core is upwards passed through in 20 contractions of a pawl 21 contraction drive earlier actuating arm smoothly in uphill process, when rising, generally do not have what problem, mainly solve in the process of transferring, prevent that the down-hole adjustment means is stuck in the water distributing core place.
