In order to realize the combination of the electric delivery tools of a plurality of eccentric water nozzles, the instrument is provided with through wires up and down, and the wire passing pipe 41 is designed for an upper lead and a lower lead. To ensure that the hole through conduit 41 remains straight and to ensure that conduit 41 is not twisted off by mishandling, the instrument uses a first spring catch 46, a second spring catch 49, a third spring catch 61 and a fourth spring catch 63 for positioning.
As shown in fig. 6, the circuit of the eccentric water nozzle electric delivery tool works as follows.
E1 is connected to ground and E2 is connected to cable. The diode CR1, the resistor R1, the regulator VR1, and the capacitor C1 constitute a power supply circuit, and the output VCC of the power supply circuit is supplied to other circuits. The capacitor C2, the resistors R2 and R3 form a signal separation circuit which separates the pulse control signal attached to the cable core and sends the separated pulse control signal to the decoder. The integrated blocks IC1A, IC1B, IC2A, resistors R4, R5 and R6, and capacitors C3, C4 and C5 form a decoder. It converts the return-to-zero code from the signal separation circuit into a non-return-to-zero code. The integrated chip IC3, the resistors R7 and R8, and the capacitors C6 and C7 constitute a decoder, which decodes the signals sent from the decoder. The connection terminals J1 to J3 are address setting terminals of the decoder. When the address of the control signal sent by the ground instrument through the E2 end is the same as the address setting, the output 11 of the IC3 changes from low level to high level, the triggering integrated block IC4A makes the output of the pin 1 high level, the triode Q1 is conducted, and the motor control panel works. If the command sent by the ground instrument is that the fishing arm 55 is opened, the output of the pin 15 of the integrated block IC3 is at high level, and the integrated block IC4B is triggered to make the output of the pin 13 at high level and the output of the pin 12 at low level. The two signals act to turn on the transistors Q4, Q3 and turn off the transistors Q5, Q2. Connected to the terminals E3, E4 is the motor 15. The current path at this time is: terminal E2 → transistor Q4 → terminal E4 → motor 15 → terminal E3 → zener diode VR2 → transistor Q3 → transistor Q1 → terminal E1. The motor 15 rotates forward, and the throwing and fishing arm 55 is opened. If the command sent by the ground instrument is that the fishing arm 55 is folded, the output of the pin 15 of the integrated block IC3 is at low level, the output of the pin 13 of the integrated block IC4B is at low level, and the output of the pin 12 is at high level. The two signals act to turn on the transistors Q5, Q2 and turn off the transistors Q4, Q3. The current path at this time is: terminal E2 → transistor Q2 → terminal E3 → motor 15 → terminal E4 → zener diode VR3 → transistor Q5 → transistor Q1 → terminal E1. At this point, the current through the motor 15 is reversed from the previous path, the motor 15 reverses direction, and the grappling arm 55 closes. Connected between the terminal E5 and ground is a hall switch. When the throwing and fishing head contacts the eccentric water nozzle, the Hall switch is switched on. The current will form a path: e2 → diode CR1 → resistor R12 → terminal E5 → Hall switch → ground. The supply current will increase. Thus, the surface instrumentation will indicate that the offset nozzle has been contacted by the fishing head.
Preferably, the throwing and fishing arm opening process of the eccentric water nozzle electric throwing and fishing tool comprises the following steps: the ground instrument sends a throwing and fishing arm opening instruction, the circuit control board 12 controls the motor 15 to rotate forward, the speed reducer 16 drives the ball screw 20 to move downwards, the push-pull sleeve 24, the telescopic sleeve 26, the telescopic push-pull rod 28, the first push-pull rod 36, the reducing connecting rod 44, the second push-pull rod 50 and the sliding block 51 all move downwards, and the throwing and fishing arm 55 is opened under the action of the second spring 54. When the throwing and fishing arm 55 is completely opened, the first switch pressing plate 21 triggers the first limit switch 22 to be closed, and the motor 15 stops rotating.
Preferably, the collecting process of the throwing and fishing arm of the electric throwing and fishing tool for the eccentric water nozzle is as follows: the ground instrument sends a gathering instruction of the throwing and fishing arm, the circuit control board 12 controls the motor 15 to rotate reversely, the speed reducer 16 drives the ball screw 20 to move upwards, and the push-pull sleeve 24, the telescopic sleeve 26, the telescopic push-pull rod 28, the first push-pull rod 36, the reducing connecting rod 44, the second push-pull rod 50 and the sliding block 51 all move upwards → the throwing and fishing arm 55 is gathered under the action of the pressing rod 52. When the throwing and fishing arm 55 is completely folded, the second switch pressing plate 25 triggers the second limit switch 23 to be closed, and the motor 15 stops rotating.
Preferably, the fishing head 59 contacts the eccentric water nozzle indication process: when the fishing head 59 contacts the water nozzle, an upward force is applied, the second push-pull rod 50, the variable diameter connecting rod 44, the first push-pull rod 36 and the telescopic push-pull rod 28 move upwards, the magnetic steel 33 moves to the position near the Hall switch 30 → the Hall switch 30 is switched on, and the circuit control panel 12 sends the signal to the ground.
