Embodiment Construction
[0012] see figure 1 , figure 2 , the specific embodiment adopts the following technical scheme: it includes a centralizing wax scraper body 1, and several tower-shaped spiral teeth 1-1 are arranged on the centralizing wax scraper body 1, and the top of the tower-shaped spiral tooth 1-1 is provided with a tower Shaped helical tooth 1-1 vertical helical baffle 1-2.
[0013] The centralizing wax scraper body 1 is provided with a longitudinal opening 1-3.
[0014] The opening size of the longitudinal openings 1-3 is 1 / 3 of the diameter of the sucker rod 2 .
[0015] In this specific embodiment, the body 1 of the righting wax scraper becomes soft after being boiled and heated, and is stuck on the sucker rod 2 by the longitudinal opening. 1 / 3 of the diameter of the sucker rod 2 can ensure that the wax scraper body 1 will not slip off from the sucker rod 2 during work, and a spiral baffle 1- 2. While the wax scraping effect of the oil pipe can be ensured, the flow area of the ...
