Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning device technology, and in particular to a sludge cleaning device for water supply and drainage pipelines. Background Technology
[0002] Water supply and drainage pipelines refer to the pipeline systems that provide water supply and drainage for urban residents, businesses, and public facilities. They consist of two parts: water supply pipelines and drainage pipelines. Water supply pipelines are responsible for transporting reclaimed water or other water sources to the point of use, while drainage pipelines are responsible for discharging wastewater, sewage, and rainwater from the point of use into the urban drainage network. Water supply and drainage pipeline systems play a vital role in the entire water supply and drainage system. They include the pipe (channel) system and various structures on it, such as pumping stations, reservoirs, pipe bridges, gate wells, sewage inspection wells, and rainwater inlets. Over time, water supply and drainage pipelines often accumulate silt, which then needs to be cleaned.
[0003] However, existing sludge cleaning devices have certain shortcomings in terms of pipe diameter adaptability. Due to the different pipe diameters of water supply and drainage pipes, general cleaning devices often cannot be used directly when faced with pipes of different diameters. Complex modifications and adjustments to the devices are required, which increases manpower and material costs. In addition, some sludge cleaning devices only use a pair of rollers to push the equipment forward, which cannot effectively distribute the weight of the device itself, causing the device to easily tilt during movement. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a sludge removal device for water supply and drainage pipelines.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A sludge removal device for water supply and drainage pipelines includes a movable pipe body, a PLC controller, a moving component, and a cleaning component. The moving component is used to move the movable pipe body back and forth, and the cleaning component is used to clean the sludge. A plurality of first support frames are evenly arranged on the outer circular wall of the movable pipe body. Second moving wheels are respectively provided at both ends of the first support frames. A support component is also provided. The support component includes: a plurality of limiting tubes fixedly installed on the outer circular wall of the movable pipe body, the limiting tubes being movably sleeved with the first support frames. A fixing hole is opened on one side of the first support frame, and a rectangular through hole is opened on the top surface of the first support frame. A plurality of threaded pipes are fixedly installed on the outer circular wall of the movable pipe body. Threaded posts are threadedly connected to the inner circular wall of the threaded pipes, and the threaded posts are movably sleeved with the rectangular through holes and the fixing holes. A hexagonal post is fixedly installed at one end of the threaded post.
[0007] As a further embodiment of this utility model, the moving component includes: a fixed tube, which is fixedly installed at one end of the moving tube body; two second support frames are movably sleeved inside the fixed tube; a first moving wheel is movably sleeved inside the second support frame; the outer circular wall of the first moving wheel has a plurality of toothed grooves; a first drive motor is fixedly installed on one side of the second support frame; the first drive motor is electrically connected to the PLC controller; one end of the drive shaft of the first drive motor is fixedly installed to the first moving wheel; a first circular through hole is opened on the top surface of the second support frame at the bottom; an electric push rod is fixedly sleeved on the inner circular wall of the first circular through hole; the electric push rod is electrically connected to the PLC controller; and the top surface of the telescopic shaft of the electric push rod is fixedly installed to the second support frame at the top.
[0008] As a further embodiment of this utility model, the cleaning component includes: a second drive motor, the second drive motor being disposed on the inner circular wall of the moving tube, two fixing plates being fixedly installed on the outer circular wall of the second drive motor, the fixing plates being fixedly installed on the inner circular wall of the moving tube, the second drive motor being electrically connected to the PLC controller, and a screw rod being fixedly installed at one end of the drive shaft of the second drive motor.
[0009] As a further embodiment of this utility model, a third support frame is fixedly sleeved on the inner circular wall of the movable tube, a third circular through hole is opened on one side of the third support frame, a bearing is fixedly sleeved on the inner circular wall of the third circular through hole, and the bearing is fixedly sleeved with the spiral rod.

[0011] As a further embodiment of this utility model, two limiting posts are fixedly sleeved inside the fixing tube.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1.

[0025] Reference Figures 1-5 A sludge removal device for water supply and drainage pipelines includes a movable pipe body 1, with a plurality of first support frames 2 disposed on the outer circular wall of the movable pipe body 1, and a PLC controller disposed on the outer circular wall of the movable pipe body 1. It also includes a plurality of second movable wheels 12 for supporting and moving the movable pipe body 1, with the first support frames 2 movably connected to the second movable wheels 12, and a support assembly for moving the movable pipe body 1. The movement assembly includes a plurality of limiting tubes 22, all of which are fixedly installed on the movable pipe body 1. The outer circular wall surface, the limiting tube 22 is movably sleeved with the first support frame 2, the first support frame 2 has a fixing hole 9 on one side, the top surface of the first support frame 2 has a rectangular through hole, the outer circular wall surface of the movable tube body 1 is fixedly installed with several threaded tubes 8, the inner circular wall surface of the threaded tubes 8 is threadedly connected with threaded posts 10, the threaded posts 10 are movably sleeved with the rectangular through hole and the fixing hole 9, one end of the threaded posts 10 is fixedly installed with a hexagonal post 11, the movable component is used to move the movable tube body 1 back and forth, and the cleaning component is used to clean the silt.
[0026] Specifically, the drainage pipe sludge cleaning device mainly consists of a moving pipe body 1, a PLC controller, a moving assembly, a cleaning assembly, and a support assembly. The PLC controller is used to control the entire device. During operation, the device is placed inside the water supply and drainage pipe. The moving assembly drives the moving pipe body 1 to move back and forth inside the pipe. During the movement, the cleaning assembly cleans the sludge from the inner wall of the pipe. Before the device enters the pipe for cleaning, the diameter of the pipe to be cleaned must be measured. Based on the measured pipe diameter data, the position of the first support frame 2 needs to be adjusted to ensure that the second moving wheel 12 can maintain a suitable distance from the inner wall of the pipe, thus achieving stable operation of the device inside the pipe. This is achieved by using an electric wrench and a hexagonal socket to tighten the hexagonal post 11. Since the hexagonal post 11 and the threaded post 10 are fixedly connected, when the hexagonal post 11 is tightened, the threaded post 10 rotates inside the fixing hole 9 on one side of the first support frame 2. The rectangular through hole on the top surface of the first support frame 2 limits the threaded post 10. The threaded post 10 and the threaded pipe 8, which is fixedly installed on the outer circular wall of the movable pipe body 1, are threadedly connected. When the threaded post 10 rotates in the fixing hole 9, it moves axially on the inner circular wall of the threaded pipe 8. As the threaded post 10 moves inside the threaded pipe 8, the first support frame 2 associated with the threaded post 10 also moves accordingly. That is, the first support frame 2 reciprocates along the axial direction of the threaded pipe 8 to adjust the position of the second moving wheel 12 to accommodate pipes of different diameters. By setting up threaded post 10, threaded tube 8, and fixing hole 9, and turning hexagonal post 11, the threaded post 10 moves axially along the inner wall of threaded tube 8, thereby adjusting the position of the first support frame 2 to adapt to pipes of different diameters. This greatly improves the versatility of the device, reduces costs, and is simple in structure and easy to operate. By setting up limiting tube 22, it is ensured that the first support frame 2 can only move back and forth along the axial direction of limiting tube 22, avoiding left and right swaying of the first support frame 2 during sludge removal, and improving the reliability and accuracy of the cleaning work. By setting multiple first support frames 22 on the outer wall of the moving tube 1, and setting second moving wheels 12 at both ends of the first support frame 22, the weight of the moving tube 1 can be distributed more evenly, making the force on each part more balanced when the device moves in the pipe, reducing the shaking and tilting of the device, and ensuring the continuous and stable progress of the cleaning operation.
[0027] In this embodiment, as Figure 3 , 5As shown, the moving component includes: a fixed tube 3, which is fixedly installed at one end of the moving tube body 1. Two second support frames 4 are movably sleeved inside the fixed tube 3. A first moving wheel 5 is movably sleeved inside the second support frame 4. The outer circular wall of the first moving wheel 5 is provided with several toothed grooves 21. A first drive motor 6 is fixedly installed on one side of the second support frame 4. The first drive motor 6 is electrically connected to the PLC controller. One end of the drive shaft of the first drive motor 6 is fixedly installed with the first moving wheel 5. A first circular through hole is provided on the top surface of the second support frame 4 at the bottom. An electric push rod 7 is fixedly sleeved on the inner circular wall of the first circular through hole. The electric push rod 7 is electrically connected to the PLC controller. The top surface of the telescopic shaft of the electric push rod 7 is fixedly installed with the second support frame 4 at the top.
[0028] In use, the movable tube 1 is placed inside the pipe. Then, the electric push rod 7 is activated to push the two second support frames 4 to move in opposite directions inside the fixed tube 3, so that the two first movable wheels 5 come into contact with the inner wall of the pipe. Then, the first drive motor 6 is controlled by the PLC controller to drive the first movable wheels 5 to rotate. The rotating first movable wheels 5 push the movable tube 1 to move back and forth under the support of several second movable wheels 12. The toothed grooves 21 improve the friction between the first movable wheels 5 and the inner wall of the pipe.
[0029] In this embodiment, as Figure 5 As shown, the cleaning assembly includes: a second drive motor 14, which is disposed on the inner circular wall of the moving tube 1; two fixing plates 15 are fixedly installed on the outer circular wall of the second drive motor 14; the fixing plates 15 are fixedly installed on the inner circular wall of the moving tube 1; the second drive motor 14 is electrically connected to a PLC controller; a screw rod 13 is fixedly installed at one end of the drive shaft of the second drive motor 14; a third support frame 18 is fixedly sleeved on the inner circular wall of the moving tube 1; a third circular through hole is opened on one side of the third support frame 18; a bearing 19 is fixedly sleeved on the inner circular wall of the third circular through hole; the bearing 19 is fixedly sleeved on the screw rod 13; two fourth circular through holes are opened on one side of the third support frame 18; a fourth circular through hole is opened on one side of the fixing plate 15; a water pipe 16 is fixedly sleeved on the inner circular wall of the fourth circular through hole; a nozzle 17 is fixedly sleeved on the outer circular wall of the water pipe 16; and two limiting posts 20 are fixedly sleeved inside the fixed tube 3.
[0030] When in use, start the water inlet pipe to allow water to enter the nozzle 17 and spray it out. At the same time, start the second drive motor 14 to drive the screw rod 13 to rotate and stir the sludge. The sludge is stirred while being flushed with water, which causes it to disperse and prevents it from clogging.
[0031] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: During production, the cable harnesses of the first drive motor 6, the second drive motor 14, and the electric push rod 7 are integrated into a single cable extending from the inside of the moving pipe 1, from the front side of the fixed pipe 3, and fixedly installed against the inner wall of the moving pipe 1. The cable is of sufficient length and is connected to the PLC controller. When the user needs to clean the sludge inside the pipe, the water pipe 16 is connected to another water inlet pipe of sufficient length. Then, the pipe's... The diameter is adjusted by varying the distance between several second moving wheels 12 according to the pipe diameter. During adjustment, an electric wrench and a hexagonal socket are used to turn the hexagonal post 11, causing the threaded post 10 to rotate inside the fixed hole 9. The threaded post 10 is limited by the rectangular through hole on the top surface of the first support frame 2. The threaded post 10 then moves inside the threaded pipe 8, causing the first support frame 2 to move inside the limiting tube 22. The limiting tube 22 supports the first support frame 2. Then, the moving pipe body 1 is placed inside the pipe, and the electric push rod 7 is activated to push the two second support frames 4 inside the fixed tube 3. The first moving wheels 5 are moved in the opposite direction, causing them to contact the inner wall of the pipe and stop moving. Then, the first drive motor 6, controlled by the PLC controller, drives the first moving wheels 5 to rotate. The toothed grooves 21 increase the friction between the first moving wheels 5 and the inner wall of the pipe. The rotating first moving wheels 5 push the moving pipe body 1 to move back and forth under the support of several second moving wheels 12. During the movement of the moving pipe body 1, it drags the pipes and cables connected to the water pipe 16, etc., to move. The water inlet pipe is activated, allowing water to enter the nozzle 17 and be sprayed out, in conjunction with... The second drive motor 14 is started to drive the screw rod 13 to rotate and agitate the sludge. The sludge is agitated while being flushed with water, causing it to disperse and preventing blockage. This achieves the overall effect of cleaning the sludge in the pipe. Several first support frames 2 support the four sides of the moving pipe 1 and work with the first moving wheels 5 to drive the moving pipe 1 to move back and forth. Several toothed grooves 21 increase the friction between the second support frame 4 and the pipe, resulting in better support for the moving pipe 1. This avoids insufficient support and outward tilting, which would affect the operation of the device and ensure the cleaning effect. It is quite practical.
