In specific implementation, the first magnet 111 and third magnet 23 antipole each other, the second magnet 121 and third magnet 23
Homopolarity each other can identical charges repel each other makes beam hanger on movable sleeve 21 by the second magnet 121 after moving a certain distance device top 1
19 move right, so that upper beam hanger 19 is moved down by moving up to be switched to, the first magnet when 2 return of device lower part later
11 there is a natural attraction between the sexes that beam hanger 19 can be made to move to left to switch back into and move up, and achievees the purpose that limiting moving distance switches mobile position.
In specific implementation, third groove 191 is engaged with the second groove 181, and the 4th groove 192 is engaged with the first groove 172, is made
Upper beam hanger 19 can be moved up when the second groove is engaged, and can be moved down, be reached through motor 14 when being engaged with the 4th groove
Control purpose hydraulic in liquid oil pocket top.
In specific implementation, the spacing of third groove 191 and the 4th groove 192 is the first bull stick 17 and the second bull stick 18
Spacing, and the first groove 172 is at a distance from movable sleeve 21 moves left and right, to make third groove 191 with 181 longitudinal pitch of the second groove
The 4th groove 192 will not be engaged with the first groove 172 during being engaged switching with the second groove 181, and movable sleeve 21 makes
The left and right switching of beam hanger 19 can be realized.
In specific implementation, the 5th groove 201 is engaged with the 7th groove 291, and the 6th groove 202 is stung with octadentate line 301

In specific implementation, the length of the 7th groove 291 and octadentate line 301 is the first trigger column 11 and the second trigger column
12 spacing, while so that upper beam hanger 19 switches moving direction change liquid oil pocket top 16, lower beam hanger 20 can be cut simultaneously
It changes.
In specific implementation, 18 left end of the second bull stick is fixedly connected with driving belt 22, and motor 14 is made to drive beam hanger control
Energy band moving gear band 7 does the top and the bottom mobile working after oil pocket has controlled while liquid oil pocket
A kind of working principle of submarine pipeline cleaning plant of the present invention is as follows.
Firstly, device top 1 to be mounted on to the upper half of submarine pipeline, the lower beam hanger 20 on device lower part 2 is inserted into dress
Setting makes device integrator in top 1, then so that device top 1 and device lower part 2 is fixed on Submarine Pipeline by card slot 8 and clamping lock 9
Road outer surface, starts motor 14 later, and motor 14 drives driving shaft 6 to drive gear band 7 to be revolved by driving belt 22
Turn, while motor 14 will drive the second bull stick 18, the second bull stick 18 drives the first bull stick 17 and itself progress side by gear 171
To opposite rotation, the second bull stick 18 passes through the second groove 181 being disposed thereon and stings with the third groove 191 on upper beam hanger 19
It closes, so that beam hanger 19 be made to move up, upper beam hanger 19 moves up the reduction of the pressure in the liquid oil pocket top 16 for making to be attached thereto,
To make the logical oil column 28 on liquid oil pocket top 16 drive clamping jaw 26 mobile to the direction far from submarine pipeline, lead to clamping jaw pedestal
Runner 27 on 25 passes through runner through-hole 24 and contacts with submarine pipeline, third bull stick 29 and the while upper beam hanger 19 moves up
Four bull sticks 30 pass through the screw thread on 292 second worm gear 302 of the first worm gear and the first bull stick 17 and the second bull stick 18 respectively thereon
173 occlusions are to rotation and direction of rotation on the contrary, third bull stick 29 is caused to be engaged the 5th groove by the 7th groove 291 thereon
201 drive lower beam hanger 20 to move up, so that the pressure in the liquid oil pocket lower part 15 that lower beam hanger 20 connects increases, to keep liquid oily
Logical oil column 28 on chamber lower part 15 is to close to the movement of the direction of submarine pipeline so that clamping jaw 26 is close to submarine pipeline, when gear band 7
The contraction of clamping jaw 26 when rotation in device top 1 makes that runner 27 is contacted with submarine pipeline and the clamping jaw 26 in device lower part 2 is overhanging
Submarine pipeline is pushed against, so that by 2 gear plate of device lower part, 10 driving device when the gear band 7 on device top 1 rotates
Portion 1 moves right while removing the attachment on submarine pipeline by the cleaning blade 5 of 4 right end of inner casing top, when device top 1
The second magnet 121 after certain distance on the second trigger column 12 is moved right to contact with third magnet 23 by through-hole 13, by
Make third magnet 23 that movable sleeve 21 be driven to move right for homopolar-repulsion setting with third magnet 23 in the second magnet 121, thus
So that beam hanger 19 is moved right is engaged the 4th groove 192 with the first groove 172 and because of the first bull stick 17 and the second bull stick 18
It turns to opposite so that upper beam hanger 19 moves down, makes pressure increase in liquid oil pocket top 16 that logical oil column 28 thereon be caused to drive folder
Seawards pipeline is adjacent to pawl 26, simultaneously because device top 1 moves to right the left end for making lower beam hanger 20 be moved to third bull stick 29, when
The 6th groove 202 and the 4th bull stick 30 while beam hanger 20 moves down down after arrival third bull stick 29 does not have at groove thereon
On octadentate line 301 be engaged, and because third bull stick 29 and the steering of the 4th bull stick 30 on the contrary, making lower beam hanger 20 to moving down
It is dynamic, make logical oil column 28 thereon drive clamping jaw 26 to the direction far from submarine pipeline so that the pressure in liquid oil pocket lower part 15 reduces
It is mobile, so that runner 27 is contacted submarine pipeline by runner through-hole 14, device lower part 2 moves right logical when gear band 7 being caused to rotate
The blade 5 for crossing right end clears up submarine pipeline attachment, when device lower part 2 drives the first trigger column 11 to be thereon moved to through-hole 13
When place, by the first magnet 111 of 11 upper end of the first trigger column and the setting that there is a natural attraction between the sexes of third magnet 23, keep beam hanger 19 left
It is mobile, reached after 30 right end of the 4th bull stick do not have at groove with beam hanger 20 at present, under the action of liquid oil pocket 15 pressure of lower part to
Upper movement can move over long distances efficiently to clear up the effect of submarine pipeline along submarine pipeline to form circulation and reach the device
Fruit.
