[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: Referring to Figures 1-4, a portable municipal pipe cleaner of this utility model includes a chassis 1. Two swivel casters are symmetrically arranged on both sides of one end of the chassis 1's bottom surface, and two rollers are symmetrically arranged on both sides of the other end of the chassis 1's bottom surface. A bracket 4 is fixed to the periphery of the top surface of the chassis 1 via bolts. An oil tank 5 is installed at one end of the top surface of the bracket 4, and a pipe retractor 6 is installed on the bracket 4. This structure, through the combination of swivel casters and rollers, enables flexible movement of the equipment on conventional terrain. The bracket 4 provides stable support for all components and is made of high-strength alloy steel. 4. It can ensure that it is not easily deformed in complex working environments, ensuring the overall structural stability of the equipment; the fuel tank 5 stores fuel to ensure power; the water pipe reel 6 is made of lightweight aluminum alloy, which is lightweight and high-strength, easy to install and operate, and its smooth surface facilitates the storage and retrieval of water pipes, preparing for dredging operations; an engine 7 is located at one end of the top surface of the chassis 1, a pump 8 is located on one side of the engine 7, a rectangular frame is located on one side of the pump 8, and a battery box 9 is inserted in the rectangular frame; a pressure reducing valve is installed on the inlet pipe of the pump 8; the engine 7 provides power to the pump 8. Power is supplied to drive the pump 8; the battery box 9 supplies power to the electrical components of the equipment; the pressure reducing valve regulates the pressure of the pump 8's inlet pipe to ensure stable and safe operation; the pump 8's inlet pipe, made of high-strength alloy steel, has strong pressure resistance, and together with the pressure reducing valve, it can effectively prevent the pipe from being damaged due to excessive pressure, ensuring reliable power and energy supply for pipe dredging operations; one end of the water pipe winding frame 6 is fitted with a rotating water inlet connector 10, the shaft of the water pipe winding frame 6 is hollow inside, and one end is connected to the rotating water inlet connector 10, and the shaft of the water pipe winding frame 6 has one... A connecting pipe for connecting water pipes extends out, and the inner end of the connecting pipe is rotatably connected to one end of the rotating water inlet connector 10. A rectangular through groove is opened on the outer wall of the water pipe reel 6 at the connecting pipe. This design allows water to smoothly enter the water pipe through the rotating water inlet connector 10, the hollow rotating shaft and the connecting pipe. The rectangular through groove facilitates the connection and reeling of the water pipe. The water pipe reel 6 is made of lightweight aluminum alloy, and its good processing performance enables the realization of the fine design such as the internal hollow structure and the external rectangular through groove, which improves the efficiency of water pipe use and thus improves the efficiency of pipe dredging operations.

[0020] In this invention, multiple threaded rods 11 are threaded around the top surface of the chassis 1. One end of each threaded rod 11 penetrates the bottom surface of the chassis 1 and is fixedly connected to a support plate 12. The other end of each threaded rod 11 is coaxially fixed to a handwheel 3. Rotating the handwheel 3 rotates the threaded rod 11, causing the support plate 12 to move up and down, facilitating adjustment of the equipment support height according to different terrains. Both the threaded rods 11 and the support plate 12 are made of high-strength alloy steel, whose high strength characteristics allow them to withstand greater pressure and tension, making them less prone to bending and deformation when adjusting the equipment support height, thus enhancing the equipment's adaptability and stability in complex terrains. The multiple threaded rods 11 are arranged in a cross shape when viewed horizontally, and two U-shaped frames 14 are symmetrically provided at both ends of the support 4. The cross-shaped arrangement of the threaded rods 11 provides even distribution and more stable support. The U-shaped frames 14 facilitate equipment handling and hoisting. Made of high-strength alloy steel, the U-shaped frames 14 have strong load-bearing capacity and are not easily broken during handling and hoisting. Combined with the adjustment of the support plate 12, this solves the problems of difficulty in moving and unstable placement of equipment in complex terrains. The design addresses certain issues and improves the ease of operation of the equipment in complex environments. Two mounting seats are symmetrically arranged on one side of the upper end of the bracket 4, and a sliding frame 2 is fitted onto each mounting seat. Both ends of the water pipe winding frame 6 are equipped with shaft seats, which are installed inside the sliding frame 2. A rubber pad is provided on the inner wall of one end of the sliding frame 2, and an installation groove is opened on the inner wall of the other end of the sliding frame 2. A locking block 13 is provided in the installation groove, and a connecting rod is fixedly connected to one end of the locking block 13. A spring is fitted onto the connecting rod, and one end of the connecting rod penetrates the outer wall of the sliding frame 2 and is fixedly connected to a... The handle and the side of the shaft seat have corresponding slots for the locking blocks 13. When installing the water pipe retractor 6, pull the handle to disengage the locking blocks 13 from the slots, insert the shaft seat into the sliding frame 2, and release the handle. The locking blocks 13 will then re-engage into the slots under the action of the spring, making the operation simple. The sliding frame 2 uses a nitrile rubber pad, which has good wear resistance and cushioning, effectively protecting the shaft seat, extending the service life of the equipment, ensuring the water pipe retractor 6 is installed firmly, and providing reliable water pipe storage and connection components for pipe dredging operations.

[0021] Working Principle: When using this invention, if the equipment needs to be moved due to complex terrain, it can be moved using the casters and rollers on the bottom of the chassis 1 if the terrain allows. If it is difficult to pass, the operator can turn the handwheel 3 on the top side of the chassis 1 to rotate the threaded rod 11, causing the support plate 12 to lower and support the equipment. Then, the equipment can be manually lifted or hoisted using the U-shaped frames 14 at both ends of the bracket 4. After the equipment is in place, adjust the threaded rod 11 to make the support plate 12 reach a suitable height to ensure stability. Connect the water pipe to the connecting pipe of the water pipe reel 6, and the water source is connected through the rotating water inlet connector 10. The water pipe flows into the hollow rotating shaft and then into the water pipe. The water pipe is pulled out through the rectangular through groove for operation, and then wound back for storage. When installing the water pipe winding frame 6, pull the handle on the sliding frame 2 to make the locking block 13 overcome the spring force and disengage from the slot. Insert the shaft seats at both ends of the water pipe winding frame 6 into the sliding frame 2. After adjustment, release the handle, and the spring pushes the locking block 13 to re-lock into the slot. During operation, the engine 7 on the chassis 1 powers the pump 8, the pressure reducing valve on the pump 8's inlet pipe regulates the pressure, and the battery box 9 powers the electrical components to ensure equipment operation. At this point, the device is in use.
