The arrangement is such that the main body of the push cylinder 2 on the side of the first circumferential groove 201 far away from the second circumferential groove 202 and the side of the convex ring 203 near the second circumferential groove 202 can slide along the inclined plane under the impact force of the high-pressure liquid, the main body of the push cylinder 2 on the side of the first circumferential groove 201 far away from the second circumferential groove 202 can abut against the first protrusion 3021, and the convex ring 203 abuts against the second protrusion 3022, so as to realize the ejection of part of the blade 302 from the body 1.
The nozzle 6 plays a critical role in order to achieve the movement of the pusher 2.
When using, not only can change the model of nozzle 6 (the hole size of the nozzle 6 of different models is different) according to actual conditions, so set up moreover, can be favorable to passing through of high-pressure liquid, play the effect of water conservancy diversion.
In the embodiment of the present invention, the nozzle 6 may include the first portion 601 and the second portion 602 which are connected, and may also be a tapered structure directly formed in the push cylinder 2, so that the push cylinder 2 may be manufactured according to actual operating requirements.
In order to better scrape the wall of the casing pipe, the number of the fixing grooves is 5-6, and the fixing grooves are uniformly distributed on the periphery of the body 1, as shown in fig. 1, 3 or 4. It will be appreciated by those skilled in the art that the number of blades 3 is the same as the number of fixation grooves, i.e. the blades 3 are evenly distributed around the circumference of the body 1.
In order to prevent the blade 302 from being ejected insufficiently and the through diameter of the sleeve after scraping from meeting the operation requirement, the scraper 3 and the pusher 2 are both made of rigid materials. Therefore, when the two contact each other, rigid contact is generated between the two, which can effectively prevent the retraction phenomenon of the blade portion 302 in the scraping process, so as to ensure that the drift diameter of the scraped sleeve reaches the design requirement.
