Description

Technical Field

[0001] This utility model relates to the field of municipal drainage engineering technology, and in particular to a guide structure for preventing blockage and clearing silt from municipal drainage pipelines. Background Technology

[0002] In municipal drainage systems, the prevention of blockages and the maintenance of dredging in drainage pipes are crucial for ensuring the normal operation of urban drainage functions. With the acceleration of urbanization, the blockage problems faced by drainage pipes are becoming increasingly complex. Existing technologies have revealed many shortcomings in practical applications, making it difficult to meet the needs for efficient blockage prevention and convenient dredging. Specific problems are as follows: Traditional drainage pipe dredging equipment often uses high-pressure water guns, dredging robots, and other devices. The dredging and conveying structure of the equipment requires additional electric drive to operate. This not only increases the cost of equipment purchase and maintenance, but also has problems such as unstable power transmission and high energy consumption. Especially in long-distance drainage pipes, the power transmission efficiency decreases significantly, causing the dredging effect to drop sharply as the pipe length increases, making it difficult to achieve continuous and efficient dredging. For existing blockages, traditional structures lack active loosening functions, requiring manual or dredging equipment to repeatedly clean the local area, resulting in low efficiency and high cost. Traditional anti-blockage and dredging structures are mostly fixed designs, and the installation and connection with the pipeline are usually done by welding, bolting, etc., which is cumbersome and time-consuming. When maintenance or replacement of parts is required, the pipeline needs to be partially disassembled, which is a lot of work and affects the normal operation of the drainage system.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1 to 7 : This utility model proposes a guide structure for preventing blockage and clearing silt in municipal drainage pipelines, comprising: a water delivery pipe 1, with two connecting sleeves 101 on the periphery of the water delivery pipe 1. The connecting sleeves 101 are cylindrical stepped structures. Two symmetrically distributed positioning shells 2 are installed on one side of the water delivery pipe 1. A set of bolt mounting holes is opened on one side of the positioning shells 2. Matching bolts are installed according to actual needs at the positions of the bolt mounting holes. After the bolts are installed, the two positioning shells 2 are securely connected. A diversion shell 3 is installed above the positioning shells 2. A set of bolt mounting holes is opened on both sides of the diversion shell 3. Matching bolts are installed according to actual needs at the positions of the bolt mounting holes. After the installation position of the diversion housing 3 is stabilized, a diversion pipe 301 is provided on one side of the diversion housing 3. The diversion pipe 301 is connected to the interior of the diversion housing 3. One side of the diversion pipe 301 is installed at the step position on the outside of the docking sleeve 101. A water inlet hole is opened at the top position of one of the positioning housings 2 and a water inlet hole is opened at the bottom position of the other positioning housing 2. The two water inlets are distributed in an alternating manner. The water inlet hole has an oval hole structure. Specifically, after the docking sleeve 101 and the diversion pipe 301 are docked, the docking sleeve 101, the diversion pipe 301, the positioning housing 2, and the diversion housing 3 form a diversion channel, providing a continuous water flow driving force for the subsequent rotating sleeve 401. In this embodiment, an outer rotating groove 102 is formed on one side of the water delivery pipe 1, and an inner rotating groove 103 is formed on the inner side of the water delivery pipe 1. The outer rotating groove 102 and the inner rotating groove 103 are both annular structures. A positioning groove is formed on each side of the positioning housing 2. The positioning groove is an arc structure and extends to the inner side of the outer rotating groove 102. Specifically, the annular outer rotating groove 102, in conjunction with the positioning groove, achieves the effect of lateral and vertical positioning between the water delivery pipe 1 and the positioning housing 2, so that the positioning housing 2 and the water delivery pipe 1 fit tightly together, preventing water leakage from gaps, and at the same time providing a support base for the rotation of the rotating sleeve 401. The rotating sleeve 401 has a rotating block on one side, which extends into the inner rotating groove 103. The outer side of the rotating sleeve 401 has a set of blades 402 arranged in a ring array. Specifically, the rotating block and the inner rotating groove 103 cooperate to provide a rotation track for the rotating sleeve 401, ensuring that the rotating sleeve 401 rotates smoothly along the pipeline axis. The high-pressure water flow inside the positioning housing 2 passes through the water inlet of the positioning housing 2 and impacts the blades 402. The blades 402 generate torque to drive the rotating sleeve 401 to rotate automatically without an additional power source, realizing the conversion of water kinetic energy into rotational mechanical energy and providing continuous driving force for dredging operations. In this embodiment, a set of vertical drain holes 403 are respectively provided on one side of the rotating sleeve 401 and the guide sleeve 406. The drain holes 403 are distributed in a ring array and have an inclined structure. Specifically, the inclined drain holes 403 can guide the water flow to spray out along the tangential direction, forming a rotating water flow effect, which enhances the flushing force on the debris inside the pipe. At the same time, the inclined angle can increase the water flow jet speed and improve the efficiency of debris removal. A docking flange is provided on one side of the rotating sleeve 401 and the guide sleeve 406. The docking flange of the rotating sleeve 401 has a set of docking blocks 405 distributed in a ring array on its outer periphery. The docking flange of the guide sleeve 406 has a set of docking blocks 405 distributed in a ring array on its outer periphery. The flange has a set of through holes on its outer periphery that correspond to the mating block 405. The mating block 405 passes through the interior of the through holes. Specifically, the mating flange and the mating block 405 cooperate to achieve quick positioning and docking of the rotating sleeve 401 and the guide sleeve 406. Initial fixing can be completed without bolts, providing a precise docking basis for subsequent locking of the clamp 5. A rotating sleeve 401 with a rotating connection is installed on the inner side of the positioning housing 2. A set of flow holes distributed in a ring array are opened on the rotating sleeve 401. A transverse guide sleeve 406 is installed on one side of the rotating sleeve 401. A clamp 5 is installed between the guide sleeve 406 and the rotating sleeve 401. In this embodiment, a stabilizing groove is provided on one side of the docking block 405. The stabilizing groove is a circular ring structure, and the inner side of the clamp 5 extends into the interior of the stabilizing groove. Specifically, the stabilizing groove of the circular ring structure fits tightly with the inner side of the clamp 5, and the clamping force of the clamp 5 rigidly locks the rotating sleeve 401 and the guide sleeve 406, preventing them from loosening and separating during rotation. The clamp 5 locking method allows for quick disassembly and assembly without tools, facilitating the maintenance and replacement of the dredging structure 4, while ensuring the structural stability during rotation. A limiting block 404 is provided on one side of the rotating sleeve 401. The limiting block 404 is a hexagonal structure, and a hexagonal groove corresponding to the limiting block 404 is provided on one side of the guide sleeve 406. The limiting block 404 extends into the interior of the hexagonal groove. Specifically, the hexagonal limiting block 404 and the hexagonal groove cooperate to form a circumferential limiting structure, ensuring that the rotating sleeve 401 and the guide sleeve 406 rotate synchronously. This structure also provides axial... The positioning reference assists the docking flange and docking block 405 to complete precise docking, improving the assembly reliability of the dredging structure 4. A set of spiral conveying blades 407 are provided on the outer side of the guide sleeve 406. The spiral conveying blades 407 have small diameters at both ends and large diameters in the middle. A set of guide grooves 408 distributed in a ring array is opened on one side of the guide sleeve 406. The guide grooves 408 have a circular arc structure. The rotating sleeve 401, blades 402, drainage holes 403, limiting blocks 404, docking blocks 405, guide sleeves 406, spiral conveying blades 407, and guide grooves 408 cooperate to form the dredging structure 4. Specifically, the spiral conveying blades 407, which are small at both ends and large in the middle, can generate axial thrust when rotating, which gathers the debris in the pipeline towards the middle and pushes it to both sides. Combined with the flushing effect of the drainage holes 403, it realizes the directional conveying and loosening of debris; the guide grooves 408 initially loosen and guide the movement of silt.

[0023] Example 2, based on Example 1, such as Figures 1-5 As shown, according to actual needs, corresponding bearings can be installed at the rotation position of the dredging structure 4 to reduce rotational friction.

[0024] Example 3, based on Example 1, such as Figures 1-5 As shown, existing technology can be used to install matching rollers on the positioning housing 2 to further stabilize and guide the overall positioning.

[0025] The working principle of this embodiment: Install a high-pressure water pump on one side of the water delivery pipe 1, referring to existing technology. Install the rotating block on one side of the rotating sleeve 401 into the inner rotating groove 103 of the water conveying pipe 1 to complete the movable assembly of the rotating sleeve 401 and the water conveying pipe 1. Fasten the two symmetrically distributed positioning shells 2 onto one side of the water conveying pipe 1 so that the positioning groove of the positioning shell 2 is precisely aligned with the outer rotating groove 102 of the water conveying pipe 1. Insert the matching bolts through the bolt mounting holes on one side of the positioning shell 2. Place the drainage housing 3 above the positioning housing 2 and align the bolt mounting holes of both; insert and tighten the matching bolts to firmly connect the drainage housing 3 and the positioning housing 2; fix one end of the drainage tube 301 to the step outside the docking sleeve 101 to complete the assembly of the diversion channel. Align the hexagonal groove of the guide sleeve 406 with the hexagonal limiting block 404 of the rotating sleeve 401, and at the same time align the through hole of the guide sleeve 406 mating flange with the mating block 405 of the rotating sleeve 401; push the guide sleeve 406 so that the limiting block 404 is fully inserted into the hexagonal groove, and the mating block 405 passes through the through hole to the preset position. Align the inner side of clamp 5 with the stabilizing groove of docking block 405, tighten clamp 5 so that the inner side is fully embedded in the stabilizing groove of the ring structure, thereby achieving rigid locking between rotating sleeve 401 and guide sleeve 406. It is necessary to cooperate with external dredging equipment to deliver water in the water delivery pipe 1. Part of the water flows into the diversion housing 3 through the diversion pipe 301, and then flows into the interior of the positioning housing 2 through the oval water inlet hole above the positioning housing 2. The high-pressure water flow impacts the blades 402 on the outer side of the rotating sleeve 401, causing the rotating sleeve 401 and the guide sleeve 406 to rotate synchronously. The rotating spiral conveyor plate 407 utilizes its structure, which is small at both ends and large in the middle, to generate axial thrust, causing debris in the pipe to flow towards the center and push it to both sides; the inclined drainage holes 403 of the rotating sleeve 401 and the guide sleeve 406 spray out tangential rotating water flow, flushing the debris on the inner wall of the pipe, and working with the spiral conveyor plate 407 to achieve the loosening and directional conveying of debris; the guide groove 408 plays a preliminary role in loosening and guiding the flowing sludge, assisting the debris to move along the preset path; If cleaning is required, loosen clamp 5 to separate rotating sleeve 401 and guide sleeve 406, and clean the residual debris in spiral conveyor blade 407 and drain hole 403 respectively, and unclog the blocked water inlet hole; replace blade 402 or spiral conveyor blade 407 in time if they are severely worn.
