[0024] 1. The utility model utilizes an opening and closing piece installed on an outer sleeve. In an accessible drainage pipe, the two extension plates are gradually moved away from each other according to the effect of the drainage pipe on the extension plates.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] A building water supply and drainage pipeline cleaning device, as Figures 1 to 3 shown, its structural relationship is as follows: The cleaning device has a columnar shape, and an opening and closing member 2 for supporting and limiting the cleaning device in the water supply and drainage pipeline is installed outside the cleaning device. The opening and closing member 2 includes at least two opening and closing groups, and each opening and closing group is arranged circumferentially around the cleaning device;

[0033] The opening and closing group includes an annular plate 23, an extension plate 24, and a spring 26; The annular plate 23 is installed and fixed to the outer side wall of the cleaning device, and a radially outward extending extension plate 24 is rotatably installed at each end thereof. A rotating pair with a rotation axis parallel to the axis of the cleaning device is formed between the annular plate 23 and the extension plate 24; The spring 26 is arranged between a pair of extension plates 24, and its two ends are respectively installed and fixed to the pair of extension plates 24, tending to make the outer ends of the pair of extension plates 24 flip and approach.

[0034] In actual use, the staff can adjust the flipping angle of a pair of extension plates 24 in each opening and closing group reasonably according to the inner diameter of the water supply and drainage pipeline to be cleaned, overcoming the elastic force of the spring 26, and then send the cleaning device into the water supply and drainage pipeline; At this time, a pair of extension plates 24 in each opening and closing group tend to flip and approach under the action of the spring 26, and this trend makes the outer ends of the extension plates 24 all press against the inner wall of the water supply and drainage pipeline, realizing the support and limitation of the cleaning device in the water supply and drainage pipeline.

[0035] Preferably, the opening and closing group further includes a moving wheel 25;

[0036] A moving wheel 25 is rotatably installed on the outer end face of the extension plate 24, and the linear velocity of the rotation of the moving wheel 25 is parallel to the axis direction of the cleaning device.

[0037] The setting of the moving wheel 25 enables the staff to more conveniently and labor-savingly adjust the axial position of the cleaning device in the water supply and drainage pipeline.

[0038] Preferably, the outer end face of the extension plate 24 is provided with rows of the moving wheels 25.

[0039] The arrangement of the moving wheels 25 in rows can better ensure its good rolling contact with the inner wall of the water supply and drainage pipeline, improving the smoothness and stability of the axial adjustment movement of the cleaning device in the water supply and drainage pipeline.

[0040] Preferably, the opening and closing member 2 includes a pair of opening and closing groups, which are respectively used as the first opening and closing group 21 and the second opening and closing group 22, and the first opening and closing group 21 and the second opening and closing group 22 are symmetrically arranged about the axis of the cleaning device.

[0041] Preferably, the cleaning device includes an outer sleeve 1 and a dispersing rod 3;

[0042] The outer sleeve 1 has a circular tubular structure and is sleeved outside the dispersing rod 3. The gap between the two forms an overflow channel 4, and the dispersing rod 3 can axially move in the outer sleeve 1 along their common axis;

[0043] The evacuation rod 3 includes an inner rod 31, a rotating head 32 and a rotating cutter 33; the inner rod 31 has a circular tubular structure, and its front end radially expands to form a rotating head 32 that is slidably fitted in the outer sleeve 1, and a rotating cutter 33 is provided in the front end opening.

[0044] Preferably, the front end of the outer sleeve 1 is circumferentially provided with notches 6 each in the shape of an arc-shaped recess.

[0045] The notch 6 is used to increase the water inlet channel at the front end position of the cleaning device, so as to increase the water inflow that the cleaning device can adapt to, and can improve the cleaning effect of the cleaning device to a certain extent and avoid blockage of the cleaning device.

[0046] Preferably, the cleaning device further includes a water filter net 5;

[0047] A material port 35 that communicates its interior with the overflow channel 4 is opened on the side wall of the first half of the inner rod 31, and a water filter net 5 in the shape of an annular structure that is sleeved outside the inner rod 31 is further axially provided between the outer sleeve 1 and the evacuation rod 3 on the second half of the inner rod 31.

[0048] Preferably, the water filter net 5 is fixedly connected to the outer sleeve 1, and a threaded structure for threaded fit installation is correspondingly provided between its interior and the outside of the second half of the inner rod 31.

[0049] Preferably, the end of the inner rod 31 radially expands to form a handle 34.

[0050] The staff can conveniently push, pull or rotate the inner rod 31 by applying force to the handle 34 to adjust the axial position of the evacuation rod 3 in the outer sleeve 1.

[0051] Figures 1 to 3This is an embodiment of the present utility model. The specific problem addressed by this specific embodiment is that during the rainy season, news about urban waterlogging caused by blocked drainage pipes emerges in an endless stream. In response to this, the inventor noticed a building water supply and drainage pipe cleaning device provided in Chinese Patent Publication No. CN210562574U. Its basic description is as follows: This utility model drives the second round rod to rotate through a motor. The second round rod drives the first round rod to rotate through a rectangular plate. The first round rod drives the mounting rod to rotate. The mounting rod drives two brushes to rotate through two vertical rods, and the two brushes rotate to clean the dirt on the inner wall of the pipe. However, the inventor believes that the structure of this utility model is relatively simple and can only clean pipes of the same size, and thus cannot clean pipes of different sizes, resulting in a relatively small scope of actual use and poor practicability. Based on the above, the inventor elaborated on a building water supply and drainage pipe cleaning device, which utilizes the opening and closing member 2 installed on the outer sleeve 1. Inside the drainage pipe that can be entered, according to the action of the drainage pipe on its extension plate 24, the two extension plates 24 gradually move away from each other. Under the action of the spring 26 between the two extension plates 24, the tendency of the two extension plates 24 to move away from each other will gradually decrease until it stabilizes. Thus, in drainage pipes with different diameters, the opening and closing member 2 can achieve adaptation inside it and cooperate with other structures to conduct in-depth cleaning inside the drainage pipe.

[0052] A building water supply and drainage pipe cleaning device includes an outer sleeve 1, and an opening and closing member 2 for adapting to the inner diameter of the drainage pipe is installed on the outer sleeve 1. An evacuation rod 3 for crushing blockages is arranged inside the outer sleeve 1. There is an overflow channel 4 between the evacuation rod 3 and the outer sleeve 1. The opening and closing member 2 includes a first opening and closing group 21 and a second opening and closing group 22. The first opening and closing group 21 and the second opening and closing group 22 are arranged in central symmetry, thus wrapping the whole of the outer sleeve 1. Both the first opening and closing group 21 and the second opening and closing group 22 include a ring plate 23 installed on the outer sleeve 1. Extension plates 24 extending towards the inner wall of the drainage pipe are rotatably connected to both ends of the ring plate 23. A moving wheel 25 for establishing a moving state inside the drainage pipe is arranged on the extension plate 24. A rubber layer for increasing the friction with the inner wall of the drainage pipe is arranged on the surface of the moving wheel 25. A spring 26 is connected between the two extension plates 24. When initially entering the drainage pipe, manually adjust the two extension plates 24 to an angle that can enter the drainage pipe. After entering, manually remove the external force applied. Thus, at this time, the extension plate 24 will only be affected by the inner wall of the drainage conduit, generating a force on the extension plate 24 and causing it to rotate a certain angle on the ring plate 23, so as to achieve the purpose of walking in the drainage pipe after the moving wheel 25 rotates on the basis that the drainage pipe can accommodate the whole cleaning device.

[0053] The evacuation rod 3 includes an inner rod 31 placed in the outer sleeve 1, and one end of the inner rod 31 is provided with a rotary head 32, and the rotary head 32 is provided with a plurality of rotary knives 33 for crushing the blockage. The other end of the inner rod 31 away from the rotary head 32 is provided with a handle 34 for rotating the inner rod 31. The inner rod 31 is hollow and the end at which the handle 34 is installed is open to facilitate the outflow of blockages or accumulated water. The width of the overflow channel 4 is the difference between the outer diameter of the inner rod 31 and the inner diameter of the drainage pipe. A water filter net 5 is provided in the overflow channel 4 to compensate for the difference between the outer diameter of the inner rod 31 and the inner diameter of the drainage pipe. A material port 35 for the entry of blockages is opened on the inner rod 31 at the left end of the water filter net 5. The outer sleeve 1 is provided with a slot 6 for the entry of water or blockages at one end close to the rotary head 32, and the opening diameter of the slot 6 is smaller than the opening width of the material port 35. An external thread is arranged on the inner rod 31 at the right end of the opening position of the material port 35, and the water filter 5 is connected to the inner rod 31 by a thread. In this scheme, the movement trajectory of the moving wheel 25 on the extension plate 24 is parallel to the extension direction of the drainage pipe, that is, it can rotate clockwise or counterclockwise after being subjected to force, and the movement power of the moving wheel 25 comes from the force of manually pushing the handle 34 into the drainage pipe or pulling out the overall cleaning device. However, when the handle 34 is manually driven to rotate, so that the inner rod 31 moves to the left or right relative to the outer sleeve 1, the moving wheel 25 cannot rotate and becomes a force to make the outer sleeve 1 stand still. Therefore, the inner rod 31 can first clean the blockage at the position where the outer sleeve 1 cannot pass, thereby increasing the dredging efficiency.
