[0019] The present invention provides a technical solution: See also Figures 1 to 4 A municipal pipeline desilting device comprises a main body 1, a mounting bracket 2 is symmetrically mounted on the inner wall of the main body 1, a desilting mechanism 3 is arranged on the mounting bracket 2, and a walking mechanism 4 is arranged on the outer circumferential surface of the main body 1.

[0020] The dredging mechanism 3 includes a sludge crushing component 31, a pipe inner wall cleaning component 32 and a power component 33. The sludge crushing component 31 crushes sludge lumps, the pipe inner wall cleaning component 32 high-pressure washes the inner wall of the pipe, and the power component 33 provides rotational power. The three work together to efficiently clean the pipe sludge, solving the problem of incomplete cleaning of traditional devices.

[0021] The sludge crushing assembly 31 includes a linkage column 311 rotatably connected to the inner side of one of the mounting brackets 2 and passing through the mounting bracket 2. A drill bit 312 is fixedly installed at one end of the linkage column 311 located on the outer side of the main body 1. A spiral conveying rod 313 rotatably connected to another mounting bracket 2 is fixedly installed at one end of the linkage column 311 located on the inner side of the main body 1. The drill bit 312 connected to the linkage column 311 breaks hard sludge lumps, and the spiral conveying rod 313 conveys the broken sludge backwards to prevent accumulation, thereby ensuring that the device can move forward unimpeded and improving the dredging efficiency.

[0022] The pipeline inner wall cleaning component 32 includes a hollow water pipe 321 fixedly installed on the end of the spiral conveying rod 313 away from the drill bit 312, an inner water diversion ring 322 connected to the inner cavity of the hollow water pipe 321 is fixedly installed on the outer side of the hollow water pipe 321, a plurality of water diversion branches 323 connected to the inner cavity of the inner water diversion ring 322 are fixedly installed on the outer circumferential surface of the inner water diversion ring 322, an outer water diversion ring 324 connected to the inner cavity of the water diversion branch 323 is fixedly installed on the end of the water diversion branch 323 away from the inner water diversion ring 322, and a plurality of high-pressure nozzles 325 connected to the inner cavity of the outer water diversion ring 324 are fixedly installed on the outer circumferential surface of the outer water diversion ring 324. Through the multi-layer water diversion structure of the pipeline inner wall cleaning component 32, the water flow is evenly distributed to the high-pressure nozzles 325, so as to realize high-pressure flushing of the inner wall of the pipeline, effectively remove sludge and impurities, and improve cleaning efficiency and thoroughness.

[0023] A universal joint 326 is fixedly installed at one end of the hollow water pipe 321 away from the spiral conveying rod 313. The universal joint 326 enables the hollow water pipe 321 to be flexibly connected to an external water pipe to adapt to pipes at different angles and positions, ensure unobstructed water flow, and provide a stable water source for cleaning the inner wall of the pipe.

[0024] The power assembly 33 includes a recessed frame 331 fixedly mounted on the outside of the main body 1 and rotatably connected to the hollow water pipe 321, a power motor 332 is fixedly mounted on the outside of the recessed frame 331, a driving gear 333 is fixedly mounted on the output end of the power motor 332, and a driven gear 334 fixedly mounted on the outer circumferential surface of the hollow water pipe 321 is meshed on the outside of the driving gear 333. Through the meshing of the recessed frame 331, the power motor 332, the driving gear 333 and the driven gear 334, the hollow water pipe 321 is provided with rotational power, ensuring that it drives the high-pressure nozzle 325 to rotate and flush the inner wall of the pipeline, thereby improving the dredging efficiency and the thoroughness of the cleaning.

[0025] Furthermore, the drill bit 312 is overall conical in shape, wherein the drill bit 312 is made of cemented carbide. The drill bit 312 is conical in shape and is made of cemented carbide, which can enhance the hardness and wear resistance of the drill bit 312, effectively break up the hard silt lumps in the pipeline, and improve the dredging efficiency.

[0026] The spiral conveying rod 313 is located in the inner cavity of the main body 1, and rotates synchronously with the drill bit 312 through the linkage column 311, so as to convey the sludge crushed by the drill bit 312 to the rear along the pipeline to prevent sludge accumulation, thereby ensuring the continuous movement of the device and the smooth progress of the dredging operation.

[0027] Furthermore, the inner water dividing ring 322 and the outer water dividing ring 324 are at the same axial point, wherein the inner water dividing ring 322 and the outer water dividing ring 324 are hollow inside. By the inner water dividing ring 322 and the outer water dividing ring 324 being at the same axial point and hollow inside, and being connected to the water dividing branch pipe 323, it is ensured that the water flows evenly from the inner water dividing ring 322 to the outer water dividing ring 324, and then is sprayed out by the high-pressure nozzle 325, so as to realize comprehensive high-pressure flushing of the inner wall of the pipeline.

[0028] Furthermore, the walking mechanism 4 includes a driven walking wheel assembly 41 and an active walking wheel assembly 42. Through the cooperation of the driven walking wheel assembly 41 and the active walking wheel assembly 42, it is ensured that the device can fit tightly and move smoothly in pipes of different diameters, thereby improving the adaptability and flexibility of dredging operations.

[0029] Furthermore, the driven traveling wheel assembly 41 includes a plurality of wheel columns 411 symmetrically mounted on the outer cylindrical surface of the main body 1, the inner cavity of the wheel column 411 is slidably connected with a movable column 412, a fastening bolt 413 having one end in contact with the movable column 412 is threadedly connected to the wheel column 411, and a driven traveling wheel 414 with a wheel frame is fixedly mounted on the end of the movable column 412 away from the main body 1. The design of the driven traveling wheel assembly 41 allows the position of the driven traveling wheel 414 with the wheel frame to be adjusted according to the diameter of the pipeline, thereby ensuring that the device is in close contact with the inner wall of pipelines of different sizes, and the position is fixed by the fastening bolt 413, thereby enhancing the adaptability and stability of the traveling mechanism 4, and ensuring the efficient implementation of the dredging operation.

[0030] Furthermore, the active walking wheel assembly 42 includes an inclined rod 421 symmetrically installed on the outside of the movable column 412, a wheel rod 422 is fixedly installed on the inner side of the inclined rod 421, a dual-axis motor mounting part 423 is fixedly installed at the middle section of the outer side of the wheel rod 422, a dual-axis motor 424 is fixedly installed on the inner side of the dual-axis motor mounting part 423, and an active walking wheel 425 is fixedly installed on the output end of the dual-axis motor 424. Through the design of the inclined rod 421, the wheel rod 422 and the dual-axis motor 424, the active walking wheel 425 is flexibly installed and driven, ensuring the stable movement and efficient dredging of the device in the pipeline.

[0031] Furthermore, the wheel rod 422 is located between the two wheel columns 411, wherein both ends of the wheel rod 422 do not contact the wheel column 411. By designing that the wheel rod 422 is located between the two wheel columns 411 and does not contact them, the flexibility of the walking mechanism 4 is ensured, interference with the wheel rod 422 is avoided, and at the same time, the stable installation and driving of the active walking wheel 425 are guaranteed, which helps the device to move smoothly and efficiently desilt in the pipeline.

[0032] Furthermore, rubber anti-skid sleeves are fixedly installed on the outer sides of the driven running wheel 414 and the driving running wheel 425 of the pulley frame, and the friction between the driven running wheel 414 and the driving running wheel 425 of the pulley frame and the inner wall of the pipeline is enhanced through the rubber anti-skid sleeves, thereby ensuring the stability and anti-skid performance of the device when it is moving in the pipeline.

[0033] When used specifically, the working principle of the present invention is as follows: When using the municipal pipeline desilting device, firstly, the position of the traveling mechanism 4 must be accurately adjusted according to the actual diameter of the pipeline to be cleaned to ensure that the device fits tightly against the inner wall of the pipeline. The specific operation steps are as follows: First, loosen the fastening bolts 413 on the driven traveling wheel assembly 41, and then adjust the position of the driven traveling wheel 414 of the belt wheel frame by pushing the movable column 412 outward or inward. Due to the linkage design of the inclined rod 421 and the wheel rod 422, while adjusting the driven traveling wheel 414 of the belt wheel frame, the active traveling wheel 425 will also move synchronously under the support of the dual-axis motor mounting member 423 and the dual-axis motor 424. When the driven traveling wheel 414 of the belt wheel frame comes into contact with the inner wall of the pipeline, tighten the fastening bolts 413 again to stabilize the positions of the driven traveling wheel 414 and the active traveling wheel 425 of the belt wheel frame, ensuring that they are close to the inner wall of the pipeline.

[0034] Next, an external water pipe is connected at the universal joint 326 to supply water to the device, and a traction rope can be tied to the outside of the device to facilitate subsequent recovery operations. The power motor 332 and the dual-axis motor 424 are started, and the dual-axis motor 424 drives the active walking wheel 425 to rotate, and then under the joint action of the driven walking wheel 414 of the wheel frame and the active walking wheel 425, the entire device can move smoothly on the inner wall of the pipeline.

[0035] At the same time, the power motor 332 drives the driving gear 333 to rotate, and the driving gear 333 meshes with the driven gear 334 fixed on the outer circumference of the hollow water pipe 321, thereby driving the hollow water pipe 321 to rotate. The water flow in the external water pipe first flows into the hollow water pipe 321, then enters the inner water distribution ring 322, and is evenly distributed to the outer water distribution ring 324 through multiple water distribution branches 323, and finally sprayed out by the high-pressure nozzle 325 in a high-pressure form, directly flushing the silt on the inner wall of the pipe, effectively avoiding the adhesion of silt.

[0036] In addition, as the hollow water pipe 321 rotates, the high-pressure nozzle 325 also rotates, and performs all-round rotational flushing on the inner wall of the pipe to ensure thorough cleaning. At the same time, the linkage column 311 drives the spiral conveying rod 313 and the drill bit 312 to rotate synchronously under power transmission. The drill bit 312 is designed to break the hard silt agglomerates in the pipeline, while the spiral conveying rod 313 is responsible for conveying the broken silt to the rear along the pipeline, effectively preventing the silt from accumulating in front of the device, thereby ensuring the continuous forward movement of the device and the smooth progress of the silt removal operation. At the same time, an external silt suction pump can be used to clean out all the silt inside the pipeline.

[0037] In summary, the municipal pipeline dredging device, through the coordinated action of the sludge crushing component 31, the pipeline inner wall cleaning component 32 and the power component 33, not only achieves efficient cleaning of the sludge on the inner wall of the pipeline, but also solves the difficulties of traditional dredging devices in dealing with sludge agglomeration and incomplete cleaning, thereby providing a strong guarantee for the long-term smooth operation of municipal pipelines and the healthy operation of cities.

[0038] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
