Embodiment
In order that those skilled in the art more fully understand the present invention program, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
In the description of the invention, it is to be understood that using " first ", " second ", " the 3rd " and etc. word limit
Parts, it is only for be easy to distinguish above-mentioned parts, such as do not have Stated otherwise, above-mentioned word does not have special contain
Justice, therefore it is not intended that limiting the scope of the invention.
Fig. 1 is refer to, the control device that a kind of exemplary intelligent plugging device of offer of the present invention stops in precalculated position should
Device can apply pipeline on-line production maintenance with pressure repairing in, in repairing intelligent plugging device enter pipeline in fluid to
The precalculated position D operations that need to be blocked, the position is located at before pipe leakage or spot failure 7.The device passes through sensing including two
Sensor, controller, field generator for magnetic and magneto converter.
The device includes two and passed through by inductive pick-up, as shown in Figure 1 first by inductive pick-up 1 and second
Inductive pick-up 2, both are arranged on outside pipeline 3 to be blocked with the first predetermined pre-determined distance.When intelligent plugging device 4 passes through
First by inductive pick-up 1 when, first produces first by inductive pick-up 1 by signal and is sent to controller 5, in intelligence
Can plugging device 4 by second by inductive pick-up 2 when, second produces second by inductive pick-up 2 by signal and sends
To controller 5.In certain embodiments, ball indicator can be used by inductive pick-up, it is conveniently directly purchased from market
It must assemble.
Field generator for magnetic, before the field generator for magnetic is arranged on the position for needing plugging device to stop, and it is pre- with second
After if distance is arranged on last on intelligent plugging device conveying direction by inductive pick-up；The work of field generator for magnetic
With being when plugging device reaches its position, a magnetic field is produced, (hereafter to be chatted with magnetic-electrical switching device on plugging device
State) coupling, produce electric current.Using the first coil 6 for being arranged on C points, C point positions and the second sensing in the present embodiment
The distance of the position of device 2 is definite value, and close to predetermined stop position D.
Controller 5 is powered by power supply 10, such as can use diesel generating set, and the alternating current for sending three-phase 380V is extremely controlled
Device 5 processed.Controller 5 is connected with first by inductive pick-up 1 and second by inductive pick-up 2, and in the output of controller 5
End electrical connection first coil 6.Controller 5 is received by the signal of inductive pick-up transmission and according to the distance of A points to B points (the
One pre-determined distance) and the time difference of reception signal determine the movement velocity of intelligent plugging device, further according to the distance (of B points to C points
Two pre-determined distances) time that intelligent plugging device is moved at first coil 6 is determined, and export and pass through to first coil 6 in the time
The DC current of over commutation filtering, to produce magnetic field.
The brakes connection of magnetic-electrical switching device, magnetic-electrical switching device and intelligent plugging device, in the present embodiment,
Magnetic-electrical switching device is the second coil 8, can so be coupled with the first coil 6 of energization and produce electric current.Intelligent plugging device has
The executing agency of brake shoe and brake shoe, the electricity of the sealed bladder of control blanket gas (or Seal Oil) can also be included in certain embodiments
Magnet valve.Second coil 8 electrically connects with magnetic valve and executing agency.When the second coil 8 produces electric current, on the one hand, executing agency
Driven, brake shoe is strutted and withstands on inner-walls of duct realization stopping, on the other hand, magnetic valve is opened, and blanket gas or Seal Oil are filled out
It is charged in sealed bladder, sealed bladder expands rapidly the sealing ultimately formed to pipeline.So, intelligent plugging device can move to predetermined
Stop position D and stop and seal.
The distance of A points and B points, and the distance of B points and C points are preferably an integer value, so facilitate controller programming
Calculate, for example, A points can be 10-15 rice to B point distances, the distance of B points to C points is 10-20 rice.
In the present embodiment, additionally provide using above-mentioned control device to control the method that plugging device stops in precalculated position,
In the lump with reference to shown in figure 2, this method comprises the following steps successively：
S1：The time difference and first of first position (A points) and the second place (B points) is passed sequentially through according to intelligent plugging device
Distance between position and the second place determines the movement velocity of the intelligent plugging device.
S2：Determined to reach the time of the 3rd position (C points) according to the movement velocity, and magnetic field is generated in the time；
S3：The electric current of driving intelligent plugging device brakes operation is generated using magnetic field.
In S2, the generating mode in magnetic field can be：First coil 6 is set in the 3rd position and electrically connected with controller 5, is led to
Cross after controller 5 filters current shaping and be output in first coil 6, to generate magnetic field.
In S3, it can be coupled by the second coil 8 for being arranged on plugging device with first coil 6 and produce electric current, and by electricity
Stream is transported to brakes.
In addition, after necessary driving is provided for intelligent plugging device brakes, controller 5 stops to first coil 6
Electric current conveys.It can so ensure that controller 5 is only powered between the several seconds before and after plugging device is by C points, both save the energy, also
Pipeline is avoided by electromagnetic pollution (pipeline is magnetized with permanent magnetic field), can by from now in welding magnetic field to pipeline
Influence minimizes.First coil 6 plugging device by when, the second coil 8 of magnetic field caused by first coil 6 and plugging device is sent out
Raw coupling, produces electric current, and now first coil 6 processed is has load operating mode, with plugging device not by or by after no-load operating mode phase
Than, the current value inputted to first coil 6 is different, accordingly, can be used for judging plugging device whether by with action, carry
The high precise degrees of positioning.
Certainly, plugging device stop after can also use plugging device position indicator examine positioning, with confirm plugging device whether stop with
The exact position of stopping.
The control device and method stopped above to intelligent plugging device provided by the present invention in precalculated position has been carried out in detail
It is thin to introduce.Specific case used herein is set forth to the principle and embodiment of the present invention, and above example is said
It is bright to be only intended to help the core concept for understanding the present invention.It should be pointed out that for those skilled in the art,
Under the premise without departing from the principles of the invention, some improvement and modification can also be carried out to the present invention, these are improved and modification
Belong in the protection domain of the claims in the present invention.
