Description

Technical Field

[0001] This utility model relates to the technical field of pipeline cleaning, and in particular to an elastic adaptive water supply and drainage pipeline cleaning and dredging device. Background Technology

[0002] After prolonged use, silt and other impurities accumulate on the inner walls of urban road sewers, causing narrowing or blockages. When sewers are blocked, they cannot function properly to drain water, resulting in large amounts of water accumulating on the road surface and causing inconvenience to pedestrians and vehicles.

[0003] The current method for unclogging and cleaning sewers involves inserting a steel cable into the sewer, rotating it to clear the blockage, and then using the friction of the cable to clean the sediment from the inner wall of the pipe. However, this method only effectively addresses the blockage, but it doesn't completely remove the sediment from the inner wall. The remaining sediment provides an "anchor point" for subsequent debris to accumulate, causing further blockages in the same location. Another type of tool for cleaning the inside of sewer pipes has a fixed specification and can only clean pipes of that specific size. This necessitates repeatedly changing the size of the cleaning tool, making the operation time-consuming and labor-intensive.

[0004] Therefore, there is a need for a device that can unclog all sizes of sewer pipes and clean the inner walls of the sewer pipes at the same time. Utility Model Content

[0005] The purpose of this invention is to solve the above problems and provide a flexible and adaptive water supply and drainage pipeline cleaning and dredging device.

[0006] The technical solution of this utility model is: an elastic adaptive water supply and drainage pipe cleaning and dredging device, including a fixed base, an adjusting plate, and a cleaning roller; the fixed base is cross-shaped, with a positioning post in the center of the top surface of the fixed base, and four sliding supports evenly distributed around the outer side of the positioning post, with a sliding groove provided in the sliding support along the radial direction of the fixed base; the adjusting plate has a sliding hole in the center, and the adjusting plate is slidably sleeved on the positioning post; a guide rod, a slider sleeved on the guide rod, and a spring are provided in the sliding groove; the spring sleeve is connected to the guide rod; one end of the spring abuts against the slider, and the other end abuts against the sliding groove; the device is also provided with several diagonal braces, one end of which is rotatably connected to the slider, and the other end is rotatably connected to the adjusting plate through a pin; the cleaning roller is fixed on the slider by a roller frame, and the axis of the cleaning roller is parallel to the axis of the positioning post; a conical drill bit is provided in the center of the bottom surface of the fixed base.

[0007] The slider is positioned at the end of the groove furthest from the positioning post. When the adjusting plate is pulled outward by external force, the diagonal brace drives the slider to slide inward, compressing the spring and reducing the overall diameter of the device, allowing it to be inserted into a smaller diameter pipe. After the external force is removed, the slider gradually returns to its original position due to the action of the spring, during which the cleaning roller is pressed against the inner wall of the pipe.

[0008] Preferably, the guide rod is connected to the fixed base via a thread. This facilitates the disassembly and replacement of the guide rod, and also makes it easy to clean debris that has fallen into the chute.

[0009] Preferably, a spring B is provided between the adjusting plate and the fixed base; spring B is sleeved on the positioning post, one end of spring B is supported and fixed to the bottom surface of the adjusting plate, and the other end is fixed to the upper surface of the fixed base. After the position of the adjusting plate is adjusted, spring B can stretch and reset the adjusting plate, and press the cleaning roller against the inner wall of the pipe through the connecting rod slider, providing greater pressure to the cleaning roller and improving the cleaning effect on the inner wall of the pipe.

[0010] Preferably, the diagonal brace includes two connecting rods, which are respectively disposed on both sides of the slider, and the connecting rods are rotatably engaged with the slider. The two connecting rods engaging with one slider ensures more even force distribution on the slider and prevents slider deflection.

[0011] Preferably, the adjustment plate is provided with an adjustment handle; the adjustment handle makes it easier to adjust the position of the adjustment plate.

[0012] Preferably, the device also includes a handle, which is coaxially connected to the positioning column. By rotating the handle, the conical drill bit can be used to break through the blockage in the pipe, while the cleaning roller rubs against the inner wall of the pipe to remove the accumulated dirt.

[0013] Furthermore, a drive motor is installed at the top of the positioning column, and the output shaft of the drive motor is connected to the positioning column via a coupling; the housing of the drive motor is fixed to the handle. Using a motor to drive the device makes it more convenient to use, and the handle is only used to control the forward and backward movement of the device.

[0014] Preferably, the surface of the conical drill bit is provided with a spiral guide groove; this not only provides friction against the blockage during rotation, but also guides the drilled-down dirt, preventing the blockage from becoming more compacted and difficult to clean.

[0015] Furthermore, the adjusting plate is square, and each set of connecting rods is connected to one side of the square adjusting plate; the square adjusting plate facilitates the installation of pins while ensuring the connection strength between the connecting rods and the adjusting plate.

[0016] Preferably, the roller frame is U-shaped, with the axis of the cleaning roller intersecting the extension line of the chute. This allows for a larger overall diameter of the device, enabling it to accommodate larger pipe sizes.

[0017] The beneficial effects of this utility model are as follows: The elastic adaptive water supply and drainage pipe cleaning and dredging device of this utility model has the following advantages:

[0018] 1. The cleaning roller and the slider of the device are fixed. The position of the cleaning roller can be adjusted along the guide rod by the slider. After adjustment, each slider has two springs to provide pressure, pressing the cleaning roller against the inner wall of the pipe, so that the two fit more tightly and the cleaning ability is better.

[0019] 2. The elastic extension and retraction of each cleaning roller can change the size of the device itself, allowing it to fit into pipes of various specifications, thus offering advantages in flexibility and adaptability.

[0020] 3. The bottom of the device is equipped with a conical drill bit, which can unclog the blockage caused by accumulated dirt in the pipe, thereby making the device more efficient in cleaning the pipe. Attached Figure Description

[0028] Example 1: See Figure 1-6 A flexible adaptive water supply and drainage pipe cleaning and dredging device includes a fixed base 01, an adjusting plate 02, and a cleaning roller 03. The fixed base 01 is cross-shaped, with a positioning post 16 located in the center of its top surface. Four sliding supports are evenly distributed around the outer surface of the positioning post 16, and a sliding groove 11 is provided in the sliding support along the radial direction of the fixed base 01. The adjusting plate 02 has a sliding hole in its center and is slidably sleeved on the positioning post 16, allowing the adjusting plate 02 to slide along the positioning post 16. A guide is provided in the sliding groove 11. The device includes a rod 12, a slider 13 sleeved on the guide rod 12, and a spring axle 14. The spring axle 14 is attached to the guide rod 12. One end of the spring axle 14 abuts against the slider 13, and the other end abuts against the groove 11. The device is also equipped with several diagonal braces. One end of the diagonal brace is rotatably connected to the slider 13, and the other end is rotatably connected to the adjusting plate 02 via a pin. The cleaning roller 03 is fixed to the slider 13 via the roller frame 31. The axis of the cleaning roller 03 is parallel to the axis of the positioning column 16. A conical drill bit 15 is provided at the center of the bottom surface of the fixed base 01.

[0029] The slider 13 is located at the end of the slide groove 11 away from the positioning post 16. When the adjusting plate 02 is pulled outward by external force, the diagonal support rod drives the slider 13 to slide inward, the spring a14 is compressed, the overall diameter of the device becomes smaller, and it can be put into a pipe with a smaller diameter; after the external force is removed, the slider 13 gradually returns to its original position due to the action of the spring a14. During this process, the cleaning roller 03 is pressed against the inner wall of the pipe.

[0030] The guide rod 12 is connected to the fixed base 01 by a thread. This facilitates the disassembly and replacement of the guide rod 12, and also makes it easy to clean debris that falls into the slide groove 11.

[0031] A spring B 17 is installed between the adjusting plate 02 and the fixed base 01. The spring B 17 is sleeved on the positioning post 16, with one end of the spring B 17 supported and fixed to the bottom surface of the adjusting plate 02 and the other end fixed to the upper surface of the fixed base 01. After the position of the adjusting plate 02 is adjusted, the spring B 17 can stretch and reset the adjusting plate 02, and press the cleaning roller 03 against the inner wall of the pipe through the connecting rod 22 and slider 13, providing greater pressure to the cleaning roller 03 and improving the cleaning effect on the inner wall of the pipe.

[0032] The diagonal brace includes two connecting rods 22, which are respectively located on both sides of the slider 13. The connecting rods 22 are rotatably engaged with the slider 13. The two connecting rods 22, in conjunction with the slider 13, enable the slider 13 to receive more even force and prevent the slider 13 from deflecting.

[0033] An adjustment handle 21 is provided on the adjustment plate 02; the adjustment handle 21 makes it easier to adjust the position of the adjustment plate 02.

[0034] The device also includes a lever 05, which is coaxially connected to the positioning column 16. By rotating the lever 05, the conical drill bit 15 can be used to break through the blockage in the pipe, while the cleaning roller 03 rubs against the inner wall of the pipe to remove the accumulated dirt.

[0035] A drive motor 04 is mounted on the top of the positioning column 16. The output shaft of the drive motor 04 is connected to the positioning column 16 via a coupling 06. The housing of the drive motor 04 is fixed to the lever 05. Using a motor to drive the device makes it more convenient to use, and the lever 05 is only used to control the forward and backward movement of the device.

[0036] The surface of the tapered drill bit 15 is provided with a spiral guide groove; it can not only provide friction against the blockage when rotating, but also guide the drilled dirt to avoid making the blockage in the pipe more compact and difficult to clean.

[0037] The adjusting plate 02 is square, and each set of connecting rods 22 is connected to one side of the square adjusting plate 02; the square adjusting plate 02 facilitates the installation of pins and ensures the connection strength between the connecting rods 22 and the adjusting plate 02.

[0038] The roller frame 31 is U-shaped, and the axis of the cleaning roller 03 intersects with the extension line of the chute 11. This allows the overall diameter of the entire device to be increased, enabling the device to accommodate larger pipe sizes.

[0039] The working process of this embodiment includes the following steps:

[0040] ① Pull the adjustment handle 21. At this time, spring A 14 is compressed, spring B 17 is stretched, and slider 13 and cleaning roller 03 retract inward.

[0041] ② Insert the cleaning roller 03 of the device into the pipe that needs to be cleaned;

[0042] ③Release the adjusting handle 21. At this time, spring A 14 gradually extends and spring B 17 gradually retracts. Spring B 17 distributes the pulling force on the adjusting plate 02 to the four sliders 13 through the connecting rod 22. At the same time, each spring A 14 applies a pushing force to the corresponding slider 13. Each slider 13 slides under the action of the two springs. Meanwhile, each cleaning roller 03 expands outward along with the slider 13. Finally, the cleaning roller 03 presses against the inner wall of the pipe.

[0043] ④ Start the drive motor 04, press down the lever 05, drive the four cleaning rollers 03 to rotate at high speed inside the pipe, the cleaning rollers 03 clean the inner wall of the pipe, and the conical drill bit 15 unclogs the pipe.

[0044] ⑤ After the cleaning and dredging are completed, turn off the drive motor 04 and pull out the device.

[0045] Example 2: Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that the device also includes a linear motor, which is located between the conical drill bit 15 and the fixed base 01. The linear motor can be activated when the conical drill bit 15 is not drilling effectively, applying greater downward pressure to the conical drill bit 15, making it easier to break through the blockage.
