The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, a kind of pair of afflux degree umbrella formula current collector, comprise central tube 1, central tube 1 outside is provided with current collecting umbrella 5, central tube 1 sidewall is provided with inlet 4, central tube 1 bottom connects leading screw frame 15, and described leading screw frame 15 inwalls are fixed with microswitch 10, middle microswitch 11, following microswitch 13 from top to bottom respectively.The outside, described central tube 1 bottom is fixed with umbrella runner 7, current collecting umbrella 5 bottoms are fixed on the umbrella runner 7, make current collecting umbrella 5 open or pack up by moving up and down of umbrella runner 7, wherein sequence number 2 is depicted as complete or collected works and flows the parachute-opening position among the figure, and sequence number 3 is depicted as half afflux parachute-opening position.Umbrella runner 7 connects the push rod 8 that is positioned at central tube 1 inside by push rod screw 6, and push rod 8 lower thread are connected with leading screw 9, and leading screw 9 middle parts are fixed with leading screw block 12, and leading screw 9 bottoms connect micro machine 17 by shaft coupling 16.Leading screw frame 15 inside also are fixed with circuit board 14, and circuit board 14 connects each switch and micro machine 17 by lead, carry out circuit control.Its control circuit principle as shown in Figure 2, wherein S1 is last microswitch 10, S2 is following microswitch 13, S3 is middle microswitch 11, B1 is a micro machine 17.
When the test withdrawal well was the low discharge well, this pair afflux degree umbrella formula current collector should use complete or collected works' stream mode.When instrument was gone into the well, two afflux degree umbrella formula current collectors generally were in initial position, and the leading screw block 12 on the leading screw 9 contacts with following microswitch 13, makes down microswitch 13 be in open position, can only pass through cable II core, cable jacket this moment to micro machine 17 power supplies.
When this pair afflux degree umbrella formula current collector when purpose is measured layer position, in the time of need strutting current collecting umbrella 5, can connect positive terminal by cable II core, cable jacket connects the negative electricity end and gives micro machine 17 power supplies, micro machine 17 rotations, driving leading screws 9 by shaft coupling 16 will rotatablely move and transfer the forward rectilinear motion to, leading screw 9 drives push rod 8 simultaneously, push rod screw 6, umbrella runner 7 is made the forward rectilinear motion, umbrella runner 7 struts current collecting umbrella 5, until leading screw block 12 in last microswitch 10 joints, make microswitch 10 be in open position, micro machine 17 outages are quit work, make leading screw 9 simultaneously, push rod 8, push rod screw 6, umbrella runner 7, current collecting umbrella 5 stop motions, current collecting umbrella 5 struts entirely, this moment, current collecting umbrella 5 was in complete or collected works' stream mode, for complete or collected works shown in the sequence number among the figure 2 flow the parachute-opening position, liquid can enter the inner chamber inflow upper end tester of central tube 1 by inlet 4.Behind the EOT, when needing to draw current collecting umbrella 5 in, can connect the negative electricity end by cable II core, cable jacket connects positive terminal and gives micro machine 17 power supplies, micro machine 17 reverse rotations driving leading screw 9 transfers the reverse rotation campaign of micro machine to the reverse linear motion, leading screw 9 drives push rod 8 simultaneously, push rod screw 6, umbrella runner 7 is done the reverse linear motion, the motion of umbrella runner 7 reverse linear can be drawn current collecting umbrella 5 in, until leading screw block 12 in following microswitch 13 joints, make down microswitch 13 be in open position, make micro machine 17 outages, make leading screw 9 simultaneously, push rod 8, push rod screw 6, umbrella runner 7, current collecting umbrella 5 stop motions, this moment, two afflux degree umbrella formula current collectors returned back to the initial position state.
