Specifically, under the driving of the motor 110, taking the case that the valve core 150 moves close to the motor 110 along the central axis direction of the transmission rod 140 when the motor 110 rotates reversely as an example, with the continuous upward movement of the valve core 150, the valve core 150 gradually breaks away from the threaded engagement with the transmission rod 140, at this time, it can be understood that the valve core 150 no longer moves along with the rotation of the transmission rod 140, and the motor 110 is idling without load. When the valve core 150 moves along with the transmission rod 140, the opening size of the water nozzle can be adjusted through the valve core 150, and the water nozzle is used for decontamination after the water nozzle is separated from threaded fit.
In this embodiment, the dirt separator 160 is coaxially disposed with the transmission rod 140, and is sleeved between the transmission rod 140 and the valve core 150, and the dirt separator 160 is connected to the transmission rod 140 through the dirt separator clutch 170; specifically, when the dirt separator clutch 170 is closed, the dirt separator 160 and the transmission rod 140 are rigidly connected into a whole, and the dirt separator 160 rotates synchronously with the rotation of the transmission rod 140; when the dirt separator clutch 170 is disconnected, the rigid connection between the dirt separator 160 and the transmission rod 140 is disconnected, the dirt separator 160 is in threaded connection with the transmission rod 140, that is, a threaded transmission is formed between the dirt separator 160 and the transmission rod 140, and the dirt separator 160 moves similarly along the central axis direction of the transmission rod 140 along with the rotation movement of the transmission rod 140, so that the dirt separator 160 can move to extend or retract the valve core 150.
In an alternative embodiment, the end of the dirt separator 160 is a screw head, and after the dirt separator 160 moves to extend out of the valve core 150, the dirt separator clutch 170 is closed again, so that the dirt separator 160 rotates synchronously with the rotation of the transmission rod 140, and the screw head at the end of the dirt separator 160 plays a role in rotating dirt.
In an alternative embodiment, the first portion further comprises: a holder 120; the retainer 120 is respectively connected with the motor 110 and the water nozzle body 200, and a rotation output shaft of the motor 110 is positioned in the retainer 120; the position detecting assembly 130 is disposed on the holder 120.
Specifically, the position detection assembly 130 includes: a position sensor 131, a cleaner upper limit position sensor 132, a spool upper limit position sensor 133, and a spool lower limit position sensor 134; the position sensor 131 is disposed on the holder 120 and is driven by the rotation output shaft of the motor 110 to move along the central axis direction of the rotation output shaft of the motor 110; the upper limit position sensor 132, the upper limit position sensor 133, and the lower limit position sensor 134 are provided in this order from top to bottom on the holder 120, respectively.
Further, taking the case that the position sensor 131 is close to the motor 110 when the motor 110 is reversed, as the position sensor 131 is close, the lower limit position sensor 134, the upper limit position sensor 133 and the upper limit position sensor 132 sequentially detect the working position information of the position sensor 131, so as to determine that the working position of the water nozzle adjusting assembly 100 is a first water nozzle adjusting position, a second water nozzle adjusting position and a decontamination position; wherein, a water nozzle adjusting section is arranged between the first water nozzle adjusting position and the second water nozzle adjusting position, namely, the working position of the water nozzle adjusting assembly 100 is the water nozzle adjusting position in the water nozzle adjusting section; a decontamination area is formed between the decontamination position and the second water nozzle adjusting position, namely, the working position of the water nozzle adjusting assembly 100 is the decontamination position in the decontamination area; and correspondingly, the control assembly 300 controls the water nozzle adjusting action and the decontamination action.
In an alternative embodiment, the position sensor 131, the upper cleaner limit position sensor 132, the upper spool limit position sensor 133, and the lower spool limit position sensor 134 are all hall sensors, and the position sensor 131 can trigger with the corresponding position sensor to generate a corresponding sensed position signal in the position sensor 131 when the position sensor 131 is close to the other sensors.
Specifically, the sensed position signal includes: a dirt remover upper position signal, a valve core upper position signal and a valve core lower position signal; when the position sensor 131 approaches the upper limit sensor 132 of the cleaner, an upper position signal of the cleaner is generated in the position sensor 131; generating an on-spool position signal in the position sensor 131 when the position sensor 131 is close to the on-spool limit position sensor 133; when the position sensor 131 approaches the spool-down limit position sensor 134, a spool-down position signal is generated in the position sensor 131.
Further, after the position sensor 131 generates the sensing position signal, the sensor at the corresponding position can detect the sensing position signal, so as to determine the working position of the water nozzle adjusting assembly 100, and then the control assembly 300 controls the water nozzle adjusting and the decontamination actions.

Specifically, an anti-rotation groove is arranged on the outer surface of the dirt separator 160, and an ejecting part perpendicular to the central axis of the dirt separator 160 is arranged on the micro actuator 180 and can be ejected or retracted; when the scrubber clutch 170 is disengaged, the rotation of the scrubber 160 is further restricted by the engagement of the ejected portion with the anti-rotation slot, so that the scrubber 160 is no longer rotated with the rotation of the transmission rod 140.
In an alternative embodiment, the second portion further comprises: the electromagnet 190 is located above the valve core 150, the electromagnet 190 is fixedly arranged and does not move along with the movement of the valve core 150, and correspondingly, a magnet 151 is arranged at a position, close to the electromagnet 190, on the upper portion of the valve core 150, wherein the magnet 151 and the electromagnet 190 are annular and are coaxial with the transmission rod 140. When the electromagnet 190 is energized, the electromagnet 190 can attract or repel the magnet 151, and the electromagnet 190 can be energized in the forward direction or in the reverse direction, so that a forward magnetic field and a reverse magnetic field are generated correspondingly, and the magnet 151 has a directional magnetic field as well, and is represented as a positive pole or a negative pole, so that attraction or repulsion is formed between the electromagnet 190 and the magnet 151. Specifically, the connection between the valve core 150 and the transmission rod 140 can be realized by using the interaction force between the electromagnet 190 and the magnet 151, and when the electromagnet 190 is electrified in the forward direction after the valve core 150 is separated from the threaded fit along with the transmission rod 140, the magnet 151 and the electromagnet 190 are attracted, and at this time, the valve core 150 is attracted and fixed by the electromagnet 190. After the decontamination is finished, the matching of the valve core 150 and the transmission rod 140 needs to be restored, the electromagnet 190 is electrified reversely, the electromagnet 190 repels the magnet 151 to form downward repulsive force, the valve core 150 moves downwards, and then the valve core 150 and the transmission rod 140 enter threaded matching again along with the forward rotation of the motor 110.
Referring to fig. 4, fig. 4 is an enlarged view of fig. 3 at a.
As shown in the figure, at the lower end of the second part, the valve core 150, the dirt separator 160 and the transmission rod 140 are coaxially sleeved in sequence from outside to inside, and a through hole is formed at the lower end of the valve core 150, so that the end part of the dirt separator 160 can extend out of the valve core 150; the dirt separator clutch 170 is respectively connected with the transmission rod 140 and the dirt separator 160, a micro actuator 180 is arranged outside the valve core 150, and an ejecting part of the micro actuator 180 penetrates through the side wall of the valve core 150 to be matched with an anti-rotation groove arranged on the outer surface of the dirt separator 160.
Referring to fig. 5 and fig. 6 in combination, fig. 5 is a schematic diagram of a water nozzle body when the water nozzle of the intelligent oilfield dispensing system performs a water nozzle adjusting action according to an embodiment of the present invention; fig. 6 is a schematic diagram of a tap body when the tap of the intelligent oilfield dispensing system performs a decontamination action according to an embodiment of the present invention.
As shown, the water nozzle body 200 includes: a stratified channel 210, a main channel 220, and a liquid outlet 230; the second part is positioned in the layering channel 210, the layering channel 210 is connected with the stratum where the water nozzle of the intelligent oilfield dispensing system is positioned through the liquid outlet 230, and the main channel 220 is connected with the next stratum; the main channel 220 communicates with the stratified channel 210. The opening and closing of the liquid outlet 230 is adjusted by driving the valve core 150 to move along the central axis direction of the transmission rod 140, and the cross-sectional area of the liquid outlet passage from the liquid outlet 230 is changed along with the complete or partial coverage of the valve core 150 on the liquid outlet 230.
In an alternative embodiment, the water nozzle body 200 further includes: a flow meter 240 is disposed in the stratified channel 210 for detecting the flow rate flowing from the stratified channel 210 into the main channel 220.
In a specific embodiment, the process of executing the water nozzle adjusting action by the water nozzle of the intelligent oilfield dispensing system is as follows: taking the example that the position sensor 131 and the valve core 150 both move close to the motor 110 along the central axis direction of the transmission rod 140 when the motor 110 rotates reversely, the liquid outlet 230 of the water nozzle of the intelligent oilfield dispensing system is completely closed by the valve core 150 in an initial state, and the motor 110 rotates reversely when the water nozzle is adjusted, so that the transmission rod 140 is driven to rotate reversely, the valve core 150 connected with the transmission rod 140 in a threaded manner moves upwards along with the reverse rotation, and the size of an opening between the valve core 150 and the liquid outlet 230 is gradually increased, namely the valve core 150 can not completely cover the opening of the liquid outlet 230 any more. At this time, the position sensor 131 also moves upward synchronously, and first reaches the first water nozzle adjustment position, and the spool lower limit position sensor 134 detects the spool lower position signal; as the position sensor 131 continues to move upwards to reach the second water nozzle adjusting position, the limiting position sensor 133 on the valve core detects a position signal on the valve core, and at the moment, the valve core 150 is disconnected with the transmission rod 140 in a threaded manner, namely, the valve core 150 does not rotate along with the transmission rod 140, namely, the motor 110 is idling without load, the electromagnet 190 is electrified positively, and the valve core 150 is fixed by being attracted by the magnet 151; when the on-spool position signal is detected, the motor 110 is controlled by the control assembly 300 to no longer rotate. That is, only in the tap adjustment section, the valve core 150 can move along the central axis direction of the transmission rod 140 along with the rotation of the transmission rod 140, and the size of the opening between the valve core 150 and the liquid outlet 230 can be changed along with the movement of the valve core 150.
Further, when the tap adjusting action is performed, the dirt separator 160 is always located in the valve core 150, and because the dirt separator clutch 170 is closed, a rigid connection is formed between the dirt separator 160 and the transmission rod 140, so that the dirt separator 160 only idles in the valve core 150 along with the rotation of the transmission rod 140; to avoid affecting the motion of the drive rod 140, the ejection portion of the micro-actuator 180 remains retracted all the time.
The process of the oil field intelligent separate injection system water nozzle executing the dirt removing action is as follows: after the liquid outlet 230 is completely opened, the motor 110 is controlled by the control assembly 300 to continue reversing, the position sensor 131 continues to move upwards after reaching the second position, and the valve core 150 is kept in a state of being disconnected with the transmission rod 140 by threads; after reaching the decontamination position, the decontaminating upper limit sensor 132 detects the decontaminating upper limit signal, the control assembly 300 controls the motor 110 to stop rotating, the ejecting part of the micro-actuator 180 ejects, and the decontaminating clutch 170 is disconnected, so that the decontaminating 160 does not move along with the rotation of the transmission rod 140, but a threaded connection is formed between the decontaminating 160 and the transmission rod 140.
The motor 110 is controlled to rotate forward by the control assembly 300, and the dirt separator 160 extends out of the valve core 150 along with the forward rotation of the transmission rod 140 and continuously moves downwards until reaching a blocking area in the layering channel 210; upon reaching the blocked area, the blockage significantly impedes movement of the scrubber 160, thereby creating a large current across the motor 110 that the control assembly 300 can detect and perform a further scrubbing action; next, the ejector of the micro-actuator 180 is retracted, the scrubber clutch 170 is closed, the control assembly 300 further controls the motor 110 to rotate forward, the scrubber 160 rotates along with the transmission rod 140 to perform rotary scrubbing, after scrubbing for a period of time, the ejector of the micro-actuator 180 is ejected, the scrubber clutch 170 is opened, the scrubber 160 continues to extend downwards, and repeated for a plurality of times until the scrubbing is completed, similar to the previous scrubbing.
Further, after the decontamination operation is completed, the decontamination device 160 needs to be retracted, the reverse operation should be performed, the ejection part of the micro-actuator 180 is ejected, the decontamination clutch 170 is opened, the control assembly 300 controls the motor 110 to rotate reversely, the decontamination device 160 moves upwards until the upper limit sensor 132 of the decontamination device detects the upper position signal of the decontamination device again, that is, the decontamination position is reached, the control assembly 300 controls the motor 110 to stop rotating, the ejection part of the micro-actuator 180 is retracted, the decontamination clutch 170 is closed, and the decontamination device 160 is retracted into the valve core 150.
Since the valve core 150 is disconnected from the transmission rod 140 when the decontamination is performed, the motor 110 needs to be controlled to rotate forward by the control assembly 300 to move down the position sensor 131 to reach the second water nozzle adjusting position, the electromagnet 190 is electrified reversely to form a downward repulsive force, and the valve core 150 moves down to be in threaded connection with the transmission rod 140 again.
