Be continuously increased, consequent make a trip number be also more and more frequently, such as more bit change, replacement downhole tool, switch
Drilling tool, short trip etc..In trip-out process, the more or less adhesion of drilling rod inside and outside wall federation goes out many drilling fluids, this
The waste of drilling fluid, also pollution environment, cleaning equipment heavy workload are not only caused, winter drilling fluid freezes to be also easy to constructor's cunning
Injured, the drilling fluid of drilling tool inner wall remaining be easy to cause drilling tool water hole to congeal, these technical problems are still solved up for technology.
Summary of the invention
To solve the above-mentioned problems, interlock annular scraping blade decontamination plant the present invention provides a kind of drilling rod inner wall.
The technical solution adopted by the present invention are as follows: a kind of drilling rod inner wall interlocks annular scraping blade decontamination plant, it is characterised in that packet
Core pipe, scraping blade group, clump weight and keg float are included, core pipe is hollow vertical tube, and scraping blade group is distributed in scraping around core pipe by circumferentially equidistant
Piece is constituted, and scraping blade group is at least two layers and is distributed up and down along core pipe axis direction, and the scraping blade of adjacent scraping blade group is interspersed, scraping blade side
It is in " O " type depending on main body, " O " type main body two sides connect side respectively wing plate, and wing plate tilts gradually downward from the inside to the outside, and scraping blade passes through branch
Arm is connect with core tube wall, and inner edge and outer rim are regarded in scraping blade group as concentric circles, and keg float is the container with an open mouth bottom of with, is floated
Bucket upper opening is connected with core pipe under shed by screw thread, and keg float bottom is connected with the cylinder stretched down, and clump weight is cylindric
It is connected to cylinder interior by being threaded into, clump weight central upper portion position is equipped with axle spring hole open upwards, spring eye
Bottom centre position is equipped with the axis hole through clump weight, and shaft is equipped in axis hole, and shaft upper end is equipped with and rides over spring eye bottom
Annular outer, spring eye is interior to be equipped with compressed spring, and compressed spring upper end withstands on keg float bottom, and compressed spring lower part is pressed in outside annular
Along upper, shaft lower end stretches out axis hole and is connected with buffer head on end, and core pipe upper opening has been connected through a screw thread closure.
Further, the closure is equipped with lacing hole, is installed with lifting rope in lacing hole.
Further, the closure is equipped with card cap.
The present invention is in use, be equipped with clump weight in keg float lower part, then reach properly by the way that counterweight is perfused into keg float
Weight, then the present apparatus is slowly put into drilling tool water hole downward by clump weight, floats on keg float on drilling fluid, and scraping blade group position is high
In drilling liquid, when carrying out trip-out operation, opposite drilling rod drilling liquid relative drop, the present apparatus is also under its Gravitative Loads
It is opposite to move down, it remains and is suspended in drilling liquid, the drilling fluid that scraping blade scrapes drilling rod inner wall is logical nearby along scraping blade and support arm
Road flows back downwards, reduces waste and pollution, and cleaning spending is reduced, and drilling tool water hole can be effectively prevent to congeal, and scraping blade is " O " type, tool
Have biggish buckling elastic module, make its be preferably adapted to drilling rod inner wall, it is more smooth by tool joint position, will not block
Stop is blocked.
Detailed description of the invention
Fig. 1 is overall schematic of the embodiment of the present invention.
Fig. 2 is schematic cross-sectional view of the embodiment of the present invention.
Appended drawing reference: 1 core pipe；2 clump weights；3 keg floats；4 scraping blades；5 wing plates；6 support arms；7 cylinders；8 spring eyes；9 axis holes；10

Specific embodiment
The embodiment of the present invention is as shown in Figure 1, 2, a kind of drilling rod inner wall interlock annular scraping blade decontamination plant be equipped with core pipe 1,
Scraping blade group, clump weight 2 and keg float 3, core pipe are hollow vertical tube, and scraping blade group is by circumferentially equidistant 4 structure of scraping blade being distributed in around core pipe
At scraping blade group is at least two layers and is distributed up and down along core pipe axis direction, and the scraping blade of adjacent scraping blade group is interspersed, and upper view is continuously
Gap, scraping blade side view main body are in " O " type, and " O " type main body two sides connect side respectively wing plate 5, and flexible material production can be used in scraping blade, such as
Rubber, can add skeleton, exterior angle can rounded corner, encountering seam crossing can preferably glide, and wing plate inclines gradually downward from the inside to the outside
Tiltedly, scraping blade is connect by support arm 6 with core tube wall, inner edge and outer rim is regarded in scraping blade group as concentric circles, upper view is in gapless ring
Shape, outer circular edge are adapted to drilling rod inner wall, and keg float is the container with an open mouth bottom of with, keg float upper opening and core pipe under shed
It is connected by screw thread, keg float bottom is connected with the cylinder 7 stretched down, and clump weight is connected to circle by being threaded into be cylindric
Cylinder is internal, and clump weight central upper portion position is equipped with axle spring hole 8 open upwards, and spring eye bottom centre position, which is equipped with, to be run through
The axis hole 9 of clump weight, axis hole is interior to be equipped with shaft 10, and shaft upper end is equipped with the annular outer 11 for riding over spring eye bottom, spring eye
Interior to be equipped with compressed spring 12, compressed spring upper end withstands on keg float bottom, and compressed spring lower part is pressed on annular outer, shaft lower end
