DETAILED DESCRIPTION

[0020] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application.

[0021] The embodiment comprises a long vertical rod 1, an upper handle 2 vertically arranged at the upper end of the long vertical rod 1, and a lower handle 3 vertically arranged at the upper middle part of the long vertical rod 1. The upper handle 2 and the lower handle 3 are used to control the whole device. When the device is controlled, one hand holds the upper handle 2 and the other hand holds the lower handle 3 to rotate the device for dredging. In order to facilitate control, a non-slip groove 19 is preferably arranged on the lower handle 3, and the device can be controlled by buckling the non-slip groove 19 with the hand. In order to be suitable for dredging of well pipes of different depths, the long vertical rod 1 with adjustable length is selected. In the embodiment, the length adjusting structure is that an adjusting rod 14 is sleeved on the upper part of the long vertical rod 1, the adjusting rod 14 can slide up and down along the long vertical rod 1, corresponding adjusting screw holes 15 are arranged on the upper part of the long vertical rod 1 and the adjusting rod 14, and the adjusting rod 14 and the long vertical rod 1 are fixed together by a bolt 16 passing through the adjusting screw holes 15.

[0022] An L-shaped support rod 4 is fixed on the side of the long vertical rod 1, the L-shaped support rod 4 is provided with a vertical sliding groove 5, the vertical sliding groove 5 does not penetrate the L-shaped support rod 4 downward, and a sliding block 6 is slidably connected in the vertical sliding groove 5. A pulling rope 7 is fixed to the lower surface of the sliding block 6 downward. A fixed pulley 8 is fixed at the bottom of the long vertical rod 1, the pulling rope 7 passes through the fixed pulley 8 and is fixed together with an arc-shaped push plate 9, the arc-shaped push plate 9 is slidably connected to an arc-shaped scraper 10, and the arc-shaped push plate 9 is slid on the arc-shaped scraper 10 by pulling the pulling rope 7. In order to guide and limit the pulling rope 7 at the long vertical rod 1, a plurality of positioning blocks 17 are preferably arranged on the long vertical rod 1 below the sliding block 6, the positioning blocks 17 are provided with positioning holes 18, and the pulling rope 7 passes through the positioning holes 18.

[0023] The arc-shaped scraper 10 is used to scrape the silt in the well pipe, and therefore the curvature of the arc-shaped scraper 10 is best matched with the curvature of the well pipe to be dredged. One end of the arc-shaped scraper 10 is fixed to the long vertical rod 1, and the two side edges of the arc-shaped scraper 10 are preferably gradually thinned outward in order to facilitate scraping of the silt on the inner wall of the well pipe.

[0024] The specific structure that the arc-shaped push plate 9 is slidably connected to the arc-shaped scraper 10 is that two limiting grooves 11 are symmetrically arranged on the upper surface of the arc-shaped scraper 10, limiting blocks corresponding to the limiting grooves 11 are integrally arranged at both ends of the arc-shaped push plate 9 downward, and the limiting blocks can slide along the limiting grooves 11. A fixing block 12 is arranged at the middle of the end of the arc-shaped scraper 10 away from the long vertical rod 1, a spring 13 is fixed to the fixing block 12, and the other end of the spring 13 is fixed to the arc-shaped push plate 9.

[0025] In use, the length of the long vertical rod 1 is adjusted according to the position of the well pipe, then the worker holds the upper handle 2 and the lower handle 3 with both hands, extends the arc-shaped scraper 10 into the well pipe opening to be dredged, and makes the arc-shaped scraper 10 close to the inner wall of the well pipe, rotates the arc-shaped scraper 10 back and forth, scrapes off the sludge on the inner wall of the well pipe, and drops the scraped sludge on the arc-shaped scraper 10. When the sludge on the arc-shaped scraper 10 is more, the arc-shaped scraper 10 is placed in the well chamber outside the well pipe, one hand holds the sliding block 6 and pulls the sliding block 6 upward, the sliding block 6 slides upward along the vertical sliding groove 5, drives the pull rope 7 upward, the pull rope 7 pulls the arc-shaped push plate 9 to slide toward the long vertical rod 1, the spring 13 is stretched, the arc-shaped push plate 9 pushes off the sludge on the arc-shaped scraper 10, and the pushed-off sludge is temporarily placed at the bottom of the well chamber outside the well pipe, which can be sucked away by the sludge suction equipment in the later period. Loosen the sliding block, and the arc-shaped push plate 9 will return to the initial position again due to the elastic force of the spring 13. In dredging, the arc-shaped scraper 10 can be rotated through the upper handle 2 and the lower handle 3 to scrape off the sludge at different positions of the well pipe opening.

[0026] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them; those skilled in the art should understand that: they can still modify the technical solutions recorded in the above examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
