DETAILED DESCRIPTION

[0045] The technical solutions 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 only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0046] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0047] Embodiment: Refer to Figures 1-4 A water treatment device for tunnel karst, comprising:

[0048] The body 1;

[0049] The water suction pipe 2 is configured to be raised and lowered relative to the body 1;

[0050] The plurality of scrapers 3 are rotationally connected in the water suction pipe 2 and in sliding contact with the inner wall of the water suction pipe 2. The side wall of the water suction pipe 2 is provided with a plurality of water suction holes, and the scraper 3 is configured to pass through the water suction hole intermittently.

[0051] The bottom plate 4 is arranged at the bottom end of the water suction pipe 2 and is configured to be raised and lowered relative to the water suction pipe 2 to rotate the plurality of scrapers 3.

[0052] The plurality of push plates 5 are rotationally fitted on the bottom plate 4 and are used to agitate karst water.

[0053] This invention features a suction pipe 2 that is raised and lowered relative to the body 1, with several rotatable scrapers 3 installed inside the suction pipe 2. During the process of the suction pipe 2 drawing karst water, the bottom plate 4 at the bottom of the suction pipe 2 is raised and lowered relative to the suction pipe 2, causing the scrapers 3 to slide and contact the inner wall of the suction pipe 2 and intermittently pass through the suction holes. This effectively maintains the water drawing effect and reduces the impact of karst water impurities blocking the suction holes on water treatment efficiency, thereby improving water treatment efficiency. At the same time, several rotatably connected baffles 5 are also installed on the bottom plate 4. During the discharge of karst water, the baffles 5 agitate the water, thereby mixing and crushing the sludge and impurities in the water, further accelerating the water treatment efficiency and ensuring the treatment effect.

[0054] Furthermore, it also includes:

[0055] The transmission rod 6 is fixed to the top surface of the base plate 4. One end of the transmission rod 6 extends into the water suction pipe 2 and is fixed to the top plate 8. The transmission rod 6 and the water suction pipe 2 are in a limited sliding connection.

[0056] At least one pair of small balls 9 are fixedly attached to the side wall of the top plate 8;

[0057] The transmission sleeve 10 is sleeved on the outside of the top plate 8. Limiting grooves are respectively opened on opposite sides of the inner wall of the transmission sleeve 10. The small ball 9 slides with the adjacent limiting groove. When the transmission rod 6 rises and falls relative to the suction pipe 2, the transmission sleeve 10 rotates back and forth relative to the suction pipe 2 through the cooperation of the small ball 9 and the limiting groove.

[0058] Among them, several scrapers 3 are axially arranged on the transmission sleeve 10 and fixed relative to the transmission sleeve 10.

[0059] Reference Figure 2 , Figure 4 By fixing a limiting rod 7 to the side wall of the transmission rod 6, the bottom end of the suction pipe 2 is slidably connected to the transmission rod 6 to prevent the transmission rod 6 from rotating relative to the suction pipe 2. During the water suction process, by lowering the suction pipe 2, the bottom plate 4 is brought into contact with the inner wall of the karst pit, thereby lifting it relative to the suction pipe 2. During the lifting process, the small ball 9 slides along the limiting groove. Since the transmission rod 6 does not rotate with the suction pipe 2, the transmission sleeve 10 rotates under the pressure of the small ball 9, which in turn drives several scrapers 5 to rotate and clean the suction holes, improving the water suction efficiency. During the lifting process of the suction pipe 2, the bottom plate 4 descends under the action of gravity, and the small ball 9 presses the transmission sleeve 10 to reset, so that the suction pipe 2 drives several scrapers 3 to rotate back and forth during the lifting process, reducing the possibility of the suction holes being blocked.

[0060] Furthermore, it also includes:

[0061] The first adapter ring 11 is sleeved and fixed on the outer periphery of the transmission sleeve 10. The bottom surface of the first adapter ring 11 is connected to the inner wall of the bottom end of the suction pipe 2 through the sliding bearing 27.

[0062] A plurality of support rods 12 are connected with the squeegee 3 in one-to-one correspondence, and are axially and equidistantly connected with the first adapter ring 11 in the vertical direction;

[0063] The second adapter ring 13 is annularly arranged at the top end of the support rod 12 and is connected with the plurality of support rods 12.

[0064] Through the connection of the plurality of support rods 12 with the first adapter ring 11 and the second adapter ring 13 respectively, the squeegee 3 is connected to the side of the support rod 12 close to the inner wall of the water suction pipe 2, which improves the structural integrity of the plurality of squeegees 3, and the first adapter ring 11 is rotatably connected to the water suction pipe 2 through the sliding bearing 27 at the bottom end of the first adapter ring 11, which ensures the rotation effect of the first adapter ring 11.

[0065] Further, it further comprises:

[0066] The spring 14 is arranged around the portion of the transmission rod 6 located in the water suction pipe 2, and the two ends of the spring 14 are respectively connected with the top plate 8 and the inner wall at the bottom end of the water suction pipe 2.

[0067] By arranging the spring 14 on the transmission rod 6 and connecting the two ends of the spring 14 with the top plate 8 and the inner wall at the bottom end of the water suction pipe 2, the reset function of the bottom plate 4 is ensured, and the transmission effect of the ball 9 and the transmission sleeve 10 is improved.

[0072] Referring to Figure 3 The rotating shaft 17 is driven to rotate by the driving motor 16, and the connecting ring 18 is driven to rotate by the rotating shaft 17, and the plurality of push plates 5 can be understood as spiral plate structures, thereby enhancing the stirring effect on karst water.

[0073] Further, it further comprises:

[0074] A pair of mounting plates 19 are connected to the machine body 1, and a through hole is formed between the pair of mounting plates 19 on the machine body 1, and the water suction pipe 2 is arranged in the through hole;

[0076] The fixed plate 21 and the snap ring 22 are lifted and lowered by the air cylinder 20, so that the water suction pipe 2 is lifted and lowered, which not only improves the water suction range, but also adjusts the state that the bottom plate 4 abuts against the ground by lifting and lowering the water suction pipe 2, and realizes the transmission effect of reciprocating rotation of the transmission sleeve 10 by controlling the lifting and lowering of the bottom plate 4 relative to the water suction pipe 2, and guarantees the cleaning effect of the water suction hole.
