the lower side wall of the through hole 28 is fixedly connected with the lug 29, so that the lug 29 stretches into the through hole 28, when the rotating shaft 21 rotates, the arc-shaped groove 22 above the rotating shaft 21 moves along with the rotation, when the rotating shaft 21 rotates, the guide block 25 slides in the arc-shaped groove 22, along with the rotation of the rotating shaft 21, the guide block 25 pushes the lantern ring 24 to move up and down, the lantern ring 24 drives the arc-shaped block to move up and down, when the arc-shaped block moves up and down, the lug 29 on the inner wall of the through hole 28 moves up and down along with the arc-shaped block, and as the lug 29 stretches into the sieve pores on the sieve tube 11, the lug 29 stretches out and stretches out the sieve pores of the sieve tube 11 when the arc-shaped plate 27 moves up and down, so that the sieve pores on the sieve tube 11 are prevented from being blocked by solid impurities in an oil field, and the permeability of the sieve tube 11 is improved; and through making lug 29 be the arc setting, and make lug 29 slope towards in the through-hole 28, make lug 29 when following arc 27 up-and-down motion, lug 29 can dredge the sieve mesh on the screen pipe 11, and then further improved the permeability of screen pipe 11, improved the filter effect of screen pipe 11.
The specific working procedure is as follows:
the pipe body 1, the screw rod 12, the screen pipe 11, the divider 3 and the pneumatic actuator are all made of the same materials as those used in the prior art, and when the pipe is used in different environments, the structural units of the pipe are the same as those of the technical pipe column in the prior art, and the specifications of the technical pipe column can be adjusted and produced according to the environmental changes; the screw rod 12 of the present application is different from the screw rod in the prior art in that the lower end of the screw rod 12 of the present application is provided with a magnetic material;
further, by installing the pipe body 1 of the present application into an oil well, the screen pipe 11 at the lower end of the pipe body 1 is inserted into an oil layer in the oil field, and then the pneumatic actuator is started, when the pneumatic actuator operates, the pneumatic actuator controls the screw rod 12 to rotate, when the screw rod 12 rotates, the spiral groove at the outer ring of the screw rod 12 conveys oil in the oil layer, the oil in the oil field is conveyed to the surface through the pipe body 1, when the oil in the oil layer passes through the screen pipe 11 in the process of entering the inside of the pipe body 1, the oil firstly passes through the screen pipe 11 and then is filtered through the screen pipe 11, so that impurity particles contained in the oil layer are blocked outside the pipe body 1, but because the force generated by the screen pipe 11 is suction force in the process of conveying the oil upwards by the pipe body 1, impurities are prevented from being adsorbed on the outer ring of the screen pipe 11 when the substances in the oil layer are sucked by the screen pipe 11, and thus blocking the screen pipe 11;
when the screw rod 12 rotates, the lower end of the screw rod 12 is made of a magnetic material, the rotating shaft 21 is made of a magnetic material, so that when the screw rod 12 rotates, the screw rod 12 and the rotating shaft 21 are attracted to each other, the rotating shaft 21 rotates, the guide block 25 moves in the arc-shaped groove 22 on the rotating shaft 21 when the rotating shaft 21 rotates, the guide block 25 pushes the sleeve ring 24 to move up and down on the outer ring of the screen pipe 11, the sleeve ring 24 pushes the spring 23 to shrink and extend up and down on the outer ring of the screen pipe 11, when the spring 23 shrinks and extends, steel wires between the spring 23 squeeze and crush oil layer impurities around the sleeve ring 24, and when the spring 23 shrinks and extends, vibration is generated, so that the impurities around the screen pipe 11 are sprung, the probability that the oil layer impurities are accumulated on the screen pipe 11 is reduced to a certain extent, and the use efficiency of a process pipe column is improved.
The front, rear, left, right, up and down are based on the viewing angle of the person, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
