Referring to fig. 4, the anti-rotation component includes an anti-rotation shaft a, and the anti-rotation shaft a is a stepped shaft having a small-diameter section, a large-diameter section, and a shoulder at a connection of the small-diameter section and the large-diameter section. In the state where the third sleeve 3040 and the fourth sleeve 316 are screwed together, a through hole penetrating through at least one side of the third sleeve 3040 and the fourth sleeve 316 is formed along the radial direction of the screwed joint. The small diameter section of the stepped shaft is inserted into the through hole, and the shoulder of the stepped shaft abuts against the inner wall of the third sleeve 3040 or the fourth sleeve 316 at the periphery of the through hole. The one end that little diameter section was kept away from to the major diameter section of step shaft can also set up elastic component b to and be used for the fixing base of fixed elastic component.

With the above technical solution, when the third sleeve 3040 is sleeved outside the fourth sleeve 316, the shoulder of the stepped shaft abuts against the inner wall of the fourth sleeve 316, and the small-diameter section of the stepped shaft can penetrate through the through hole under the action of the elastic member. When the third sleeve 3040 needs to be detached from the fourth sleeve 316, the stepped shaft may be pressed downward such that the small-diameter section of the stepped shaft is withdrawn from the through hole of the third sleeve 3040, and at this time, the elastic member b is compressed. Based on this, the detachment of the third sleeve 3040 and the fourth sleeve 316 is achieved.

A plurality of through holes can be formed along the length direction of the screwed joint, and the adjusting part 31 with different specifications can be adapted to the through holes. For example, when the length of the fourth sleeve 316 provided in the adjustment portion 31 is relatively short, the through hole provided in the fourth sleeve 316 may be fitted to the through hole provided in the proximal end portion of the third sleeve 3040. For another example, when the length of the fourth sleeve 316 of the adjustment portion 31 is relatively long, the through hole of the fourth sleeve 316 may be matched with the through hole of the third sleeve 3040 away from the end.

Referring to fig. 1 to 4, in practical application, the easily replaceable flow measuring and adjusting device 3 provided in the embodiment of the present invention selects the adjusting portion 31 matched with the downhole water distributor 2 according to the requirement of the downhole water distributor 2, and screws the fourth sleeve 316 of the adjusting portion 31 to the third sleeve 3040 of the main body portion 30, and further reinforces the third sleeve 3040 and the fourth sleeve 316 which are screwed together by using the rotation-preventing component. The wireline 4 is then lowered using a winch 5 to bring the easily replaceable flow measuring and regulating device 3 into the injection well 1. In the process, under the action of gravity, the bearing seat and the cam included in the clutch assembly 311 move downwards along the axial direction of the fifth sleeve 317 and the transmission shaft 310 penetrating through the fifth sleeve 317 does not move, and at this time, the small-diameter section hole of the cam can be clamped on the boss of the transmission shaft 310. The motor assembly 304 is started, the motor assembly 304 drives the transmission shaft 310 to rotate, the rotating shaft drives the cam to rotate, and the cam drives the positioning pawl 312 to rotate, so that the positioning pawl 312 is in an open state. When the positioning pawl 312 is seated on the water distributor 2, the water distributor 2 applies upward force to the positioning pawl 312, and the positioning pawl 312 pushes the cam upward, so that the hole with the small diameter section of the cam moves upward, that is, the boss of the transmission shaft 310 is accommodated in the hole with the large diameter section of the cam. The anti-rotation claws 313 and the fixing claws 3151 are snap-fitted in grooves provided in the water distributor 2. When the motor assembly 304 is restarted, because the cam included in the transmission shaft 310 and the clutch assembly 311 is in a power cut-off state, at this time, the transmission shaft 310 transmits power to the speed reduction assembly 314, the speed reduction assembly 314 drives the adjusting assembly 315 to rotate, and the adjusting assembly 315 drives the water distributor 2 to rotate so as to adjust the opening degree of the water distributor 2, thereby realizing the flow rate of the oil displacement medium output by the water distributor 2.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
