Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below. The embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts, all belong to the protection scope of the present invention.
Referring to fig. 1 to 3, the present invention provides a technical solution: a self-cleaning water injection wellhead device comprises a pipeline 1, wherein the pipeline 1 is a connecting pipe for a water injection wellhead;
the middle parts of the left side and the right side of the pipeline 1 are provided with filter screens 2, the middle parts of the filter screens 2 are fixedly connected with connecting frames 21, and the middle parts of the inner sides of the connecting frames 21 are rotatably connected with studs 3.
The left end of the stud 3 is rotatably connected with the right middle part of the left connecting frame 21 through a bearing seat, and the right end of the stud 3 penetrates through the middle part of the right connecting frame 21 and is in transmission connection with a motor.
The left side of the stud 3 is fixedly connected with a fixing ring 31, the right side of the fixing ring 31 is fixedly provided with three telescopic rods 41, and the three telescopic rods 41 are uniformly distributed on the right side of the fixing ring 31.
The left end of the telescopic rod 41 is fixedly connected with the left side of the cleaning wheel 4, and the cleaning wheel 4 is arranged in the pipeline 1 and movably connected with the pipeline 1.
The middle part of the cleaning wheel 4 is sleeved on the stud 3, the cleaning wheel 4 is rotatably connected with the inner wall of the pipeline 1, and the outer wall of the cleaning wheel 4 is paved with a brush 42.
The middle part of the right side of the cleaning wheel 4 is provided with a rotating ring 5, the rotating ring 5 is rotatably connected with the cleaning wheel 4, and the rotating ring 5 is sleeved on the stud 3.
The inner wall of the rotating ring 5 is in threaded connection with the stud 3, the upper side and the lower side of the rotating ring 5 are fixedly connected with the middle part of the inner side of the limiting block 51 through the connecting rod, and the limiting block 51 is arranged in the upper inner wall and the lower inner wall of the pipeline 1 and is in horizontal sliding connection with the pipeline 1.
The working principle is as follows: water in the water injection well head flows to the right side from the left side of pipeline 1, and the solid impurity circulation in the filter screen 2 separation pipeline 1 through both sides in the pipeline 1 prevents that the impurity in the pipeline 1 from getting into the oil field along with rivers.
When the pipeline 1 is cleaned, the motor on the right side of the right connecting frame 21 drives the stud 3 to rotate.
Because the rotating ring 5 is in threaded connection with the stud 3 and the limiting blocks 51 on the upper side and the lower side limit the rotation of the rotating ring 5, the rotating ring 5 horizontally moves left and right along the stud 3.
And because the rotating ring 5 is arranged at the right side of the cleaning wheel 4, the cleaning wheel 4 is pulled to horizontally move in the pipeline 1 by the movement of the rotating ring 5.
The left side of the cleaning wheel 4 is fixed with the right side of the fixing ring 31 through the telescopic rod 41, and the fixing ring 31 and the stud 3 are mutually fixed, so that the cleaning wheel 4 rotates in the process of horizontal movement through the transmission action of the fixing ring 31 and the telescopic rod 41 in the rotating process of the stud 3.
The brush 41 on the outer side wall of the cleaning wheel 4 rotates and moves on the inner wall of the pipeline 1, so that residual scale or dirt on the inner wall of the pipeline 1 is scraped and cleaned, and the blockage caused by the attachment of the impurities on the inner wall of the pipeline 1 is avoided.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
