Description

Technical Field

[0001] This utility model belongs to the field of pipeline-related technology, and in particular relates to a drainage pipeline dredging device. Background Technology

[0002] Drainage pipes are pipe systems used for drainage. Their length calculations must cover all main drainage pipes, branch pipes, inspection wells, and connection wells, including inlets and outlets. Drainage pipes are primarily used for drainage, mainly wastewater. Over time, this wastewater will accumulate silt at the bottom of the drainage pipes. As the silt increases, it will gradually clog the pipes, reducing water flow. Therefore, regular silt removal is necessary. However, the following drawbacks still exist in actual silt removal operations: Common pipe cleaning methods include scraper cleaning or high-pressure flushing. When scraper cleaning is used, sludge will accumulate continuously. When too much sludge accumulates, it cannot be discharged from the pipe, making cleaning too difficult. Using a sludge pump to remove sludge further increases the difficulty of cleaning, and it is difficult to coordinate the use of a sludge pump to remove sludge with scraper cleaning. High-pressure flushing is also difficult to remove sludge completely. Secondly, high-pressure washing is still insufficient to clean some stubborn hardened sludge, requiring a lot of cleaning time and failing to remove the hardened sludge quickly. Secondly, high-pressure flushing usually only flushes the direction of the sludge, but during these flushing processes, a large amount of sludge may splash onto the inner wall of the pipe, leaving sludge residue that cannot be cleaned completely. Finally, the pipe lengths are inconsistent, and the same dredging device cannot enter pipes of different lengths for cleaning. The pipe inner diameter also varies, resulting in limited applicability and a certain limitation on the dredging range. Utility Model Content

[0003] The purpose of this utility model is to provide a drainage pipe dredging device. By setting up a base, a high-pressure flushing pipe, a motor, a breaking rod, a high-pressure nozzle, a rotating nozzle, a cleaning pipe, a base, a traction rope, and an adjusting rod, it solves the problems of difficult scraper cleaning, cumbersome operation, difficulty in cleaning hardened sludge, sludge residue after high-pressure flushing, and limited length and applicability of the dredging device.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a drainage pipe dredging device, including a base, a motor, a main pipe, a high-pressure flushing pipe, a cleaning pipe and an adjusting rod. The base has adjusting grooves in both ends and adjusting blocks are fixed on both sides of the base. A cross slider is movably inserted into the adjusting block. A support rod is fixed at the end of the cross slider away from the adjusting block. An elastic element is fixed at the end of the support rod away from the cross slider. A roller is rotatably connected to the end of the elastic element away from the support rod. An adjusting rod is rotatably connected through the adjusting groove, and both ends of the adjusting rod extend into the adjusting block and are threadedly connected to the cross slider. A motor is installed below the base, and an end plate is fixed on the output shaft of the motor. Two crushing rods are threadedly connected to the outer circumference of the end plate. Crushing teeth are evenly distributed on the outer circumference of the end of the crushing rods away from the end plate. A high-pressure flushing pipe is provided below the base on the front side of the motor, and two rows of high-pressure nozzles are fixed through the outer periphery of the high-pressure flushing pipe. A cleaning pipe is provided below the base on the rear side of the motor, and a rotating nozzle is fixed to the end of the cleaning pipe away from the motor.

[0005] Furthermore, the portion of the adjusting rod extending into the adjusting block is threaded to form a threaded segment. The threaded segment of the adjusting rod is threadedly connected to the cross slider within the adjusting block. The length of the adjusting rod is equidistant from the sum of the lengths of the two adjusting blocks and the end width of the base. The length of the cross slider is less than the length of the adjusting block. The adjusting block is provided with a cross groove that matches the size of the cross slider.

[0006] Furthermore, an adjusting ring is fixed in the middle of the adjusting rod located in the adjusting groove, and the adjusting groove extends through the upper and lower ends of the base.

[0007] Furthermore, a lifting ring is fixed to the front end of the top surface of the base, and a traction rope is provided on the outer sleeve of the lifting ring.

[0008] Furthermore, the base has two supports fixed at its bottom, and the motor is fixed inside the two supports; the base bottom surface on the front side of the supports is provided with an arc groove, which is located on the rotation path of the crushing rod.

[0009] Furthermore, two ring blocks (I) parallel to the side of the base are fixed on the bottom surface of the base on the front side of the arc groove, and the high-pressure flushing pipe is fixed inside the ring blocks (I). Two ring blocks (II) perpendicular to the side of the base are fixed on the bottom surface of the base behind the bracket, and the cleaning pipe is fixed inside the ring blocks (II).

[0010] Furthermore, an inverted U-shaped main pipe is fixedly inserted through the base, and a branch pipe is fixedly inserted through the upper middle part of the main pipe. The two ends of the main pipe are connected to a high-pressure flushing pipe and a cleaning pipe respectively after passing through the base.

[0011] Furthermore, the upper set of high-pressure nozzles is at a 15° angle to the central axis of the high-pressure flushing pipe, while the lower set of high-pressure nozzles is at a 60° angle to the central axis of the high-pressure flushing pipe.

[0012] This utility model has the following beneficial effects: This invention solves the problems of difficult and cumbersome scraper cleaning by setting up a base and a high-pressure flushing pipe. Instead of the conventional scraper cleaning method, the base is placed at the end of the pipe. The adjusting rod is rotated until the rollers abut against the inner wall of the pipe. High-pressure water is then introduced through a branch pipe into the main pipe, and then into the high-pressure flushing pipe, spraying out from two rows of high-pressure nozzles. The nozzles are tilted downwards to flush the sludge. As the water flow propels the sludge from the bottom of the pipe, it is washed away, and the entire device is propelled deeper into the pipe until the entire pipe is cleaned. This process is repeated.

[0013] This invention solves the problem of difficult cleaning of hardened sludge during high-pressure flushing by incorporating a motor, a crushing rod, a high-pressure nozzle, and a high-pressure flushing pipe. During the sludge removal operation, the motor drives the end plate to rotate, which in turn rotates the crushing rod according to the thickness of the sludge, allowing the crushing rod to break up the sludge without damaging the pipe. The end plate has a threaded groove that connects to the threaded part on the crushing rod, allowing for adjustment of the length of the crushing rod extension. This invention is suitable for pipes of different inner diameters and for the step-by-step treatment of thicker hardened sludge. It is further combined with the high-pressure flushing pipe and high-pressure nozzle for flushing operations.

[0014] This invention solves the problem of sludge residue remaining after high-pressure rinsing by setting a rotating nozzle and a cleaning pipe. During the high-pressure rinsing process, the high-pressure water input into the cleaning pipe is sprayed out through the rotating nozzle. As the base moves synchronously, it continuously rinses the inner wall of the pipe, cleaning it both before and after high-pressure rinsing, and always keeping the inner wall of the pipe free of residual sludge.

[0015] This invention solves the problems of limited length and narrow applicability of dredging devices by setting up a base, traction rope, and adjusting rod. The entire device can penetrate deep into the pipe for cleaning, and the working stroke depends on the length of the traction rope and branch pipe (the traction rope and branch pipe are only a part in the attached drawings, and their lengths can be adjusted as needed), thus making it suitable for dredging pipes of various lengths. Secondly, by rotating the adjusting rod, the extension length of the cross slider can be adjusted, thereby controlling the position of the support rod and roller, and thus adapting to pipes of various widths.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1-7 As shown, this utility model is a drainage pipe dredging device, including a base 1, a motor 2, a main pipe 3, a high-pressure flushing pipe 4, a cleaning pipe 5, and an adjusting rod 6. Adjusting grooves 104 are provided in both ends of the base 1, and adjusting blocks 101 are fixed on both sides of the base 1. A cross slider 102 is movably inserted into the adjusting block 101. A support rod 103 is fixed at the end of the cross slider 102 away from the adjusting block 101. An elastic element 1031 is fixed at the end of the support rod 103 away from the cross slider 102, and a roller 1032 is rotatably connected to the end of the elastic element 1031 away from the support rod 103. An adjusting rod 6 is rotatably connected through the adjusting groove 104, and both ends of the adjusting rod 6 extend into the adjusting block 101 and are threadedly connected to the cross slider 102. The adjusting rod 6 in the rotating adjusting groove 104 causes the cross slider 102 in the adjusting block 101 to move, so that the two cross sliders 102 connected on the same adjusting rod 6 move away from or closer to each other. This is suitable for pipes of different widths. The movement of the cross slider 102 can also cause the movement of the support rod 103, thereby adjusting and controlling the roller 1032 to abut against the inner wall of the pipe. The elastic element 1031 can achieve elastic abutment and reduce loosening. A motor 2 is installed below the base 1. An end plate 201 is fixed on the output shaft of the motor 2. Two crushing rods 202 are threadedly connected to the outer periphery of the end plate 201. Crushing teeth 2021 are evenly distributed on the outer periphery of the end of the crushing rods 202 away from the end plate 201. When motor 2 operates, it drives end plate 201 to rotate. The crushing rod 202 is pre-threaded into end plate 201. End plate 201 has a threaded groove of a certain depth. The connection between crushing rod 202 and end plate 201 is threaded, which can control the extension length of crushing rod 202. It is suitable for pipes with different inner diameters and for the step-by-step treatment of thick sludge. The crushing rod 202 containing crushing teeth 2021 contacts the sludge to crush it, thus accelerating the dredging process.

[0021] A high-pressure flushing pipe 4 is provided below the base 1 on the front side of the motor 2, and two rows of high-pressure nozzles 401 are fixed through the outer periphery of the high-pressure flushing pipe 4. After high-pressure water is introduced into the high-pressure flushing pipe 4, it is sprayed out from two rows of high-pressure nozzles 401 at different angles, making the flushing more comprehensive and no longer a single-angle flush. With a large number of high-pressure nozzles 401, the flushing surface is larger and the flushing angle is more challenging. A cleaning pipe 5 is provided below the base 1 on the rear side of the motor 2, and a rotating nozzle 501 is fixed at the end of the cleaning pipe 5 away from the motor 2. High-pressure water is introduced into the cleaning pipe 5 and sprayed out from the rotating nozzle 501. The rotating nozzle 501 rotates and washes the inner wall of the pipe. As the base 1 moves into the pipe, it first performs a preliminary wash. When the base 1 is pulled out by the traction rope 1051, it is washed again to clean the sludge on the inner wall of the pipe.

[0022] The portion of the adjusting rod 6 that extends into the adjusting block 101 is threaded to form a threaded section. The threaded section of the adjusting rod 6 is threadedly connected to the cross slider 102 in the adjusting block 101. The length of the adjusting rod 6 is equal to the sum of the lengths of the two adjusting blocks 101 and the end width of the base 1. The length of the cross slider 102 is less than the length of the adjusting block 101. The adjusting block 101 is provided with a cross groove that matches the size of the cross slider 102. An adjusting ring 601 is fixed in the middle of the adjusting rod 6 located in the adjusting groove 104, and the adjusting groove 104 passes through the upper and lower ends of the base 1; The connection between the adjusting rod 6 and the base 1 is smooth. The threaded section is only provided on the adjusting rod 6 inside the adjusting block 101. By rotating the adjusting rod 6 through the adjusting ring 601, the two threaded sections on the adjusting rod 6 have opposite thread directions. Therefore, when the adjusting rod 6 rotates, the two cross sliders 102 connected to it are restricted by the adjusting block 101 and can only move away from or closer to each other, thereby changing the extension length of the support rod 103 and the roller 1032. It is suitable for use in pipes of various inner diameters.

[0023] A lifting ring 105 is fixed to the front end of the top surface of the base 1, and a traction rope 1051 is provided on the outer sleeve of the lifting ring 105. The lifting ring 105 is connected to the traction rope 1051, which facilitates the control of the entire device. When the device moves to the deepest part of the pipe, it is pulled out by the traction rope 1051 and pulled to the pipe opening for cleaning again until it is clean.

[0024] Two brackets 106 are fixed to the bottom of the base 1, and the motor 2 is fixed inside the two brackets 106; an arc groove 107 is provided on the bottom surface of the base 1 on the front side of the bracket 106, and the arc groove 107 is located on the rotation path of the crushing rod 202; the motor 2 is installed using the bracket 106, and the motor 2 drives the crushing rod 202 to pass through the arc groove 107 during operation without contacting the base 1.

[0025] Two ring blocks 108 parallel to the side of the base 1 are fixed on the bottom surface of the base 1 in front of the arc groove 107. The high-pressure flushing pipe 4 is fixed inside the ring block 108. Two ring blocks 109 perpendicular to the side of the base 1 are fixed on the bottom surface of the base 1 behind the bracket 106. The cleaning pipe 5 is fixed inside the ring block 109. Two ring blocks 108 are used to assist in fixing the high-pressure flushing pipe 4, and two ring blocks 209 are used to assist in fixing the cleaning pipe 5.

[0026] An inverted U-shaped main pipe 3 is fixed through the base 1. A branch pipe 301 is fixed through the upper middle part of the main pipe 3. The two ends of the main pipe 3 pass through the base 1 and are respectively connected to the high-pressure flushing pipe 4 and the cleaning pipe 5. The high-pressure water is connected to the outside through the branch pipe 301 and introduced into the main pipe 3, and then into the high-pressure flushing pipe 4 and the cleaning pipe 5.

[0027] The upper set of high-pressure nozzles 401 is at a 15° angle to the central axis of the high-pressure flushing pipe 4, while the lower set of high-pressure nozzles 401 is at a 60° angle to the central axis of the high-pressure flushing pipe 4. The two rows of high-pressure nozzles 401 at different angles flush the sludge accumulated at the bottom of the pipe, making the flushing efficiency higher.

[0028] The specific working principle of this utility model is as follows: First, the base 1 is placed at the end of the pipe. The adjusting rod 6 is rotated by the adjusting ring 601. The two threaded sections on the adjusting rod 6 have opposite thread directions. Therefore, when the adjusting rod 6 rotates, the two cross sliders 102 connected to it are restricted by the adjusting block 101 and can only move away from or closer to each other, thereby changing the extension length of the support rod 103 and the roller 1032 until the roller 1032 abuts against the inner wall of the pipe. The elastic element 1031 can achieve elastic abutment and reduce loosening. Then, the branch pipe 301 is used to connect to the external high-pressure water and input it into the main pipe 3, and then into the high-pressure flushing pipe 4 and the cleaning pipe 5. The cleaning water in the high-pressure flushing pipe 4 is sprayed out from the high-pressure nozzle 401. The high-pressure nozzle 401 is tilted downward to perform high-pressure flushing on the sludge. With the push of the water flow, the sludge at the bottom of the pipe is washed away, and the entire device will also be pushed to move deeper into the pipe (e.g. Figure 1 (The pointed tip indicates the direction) until the entire pipe is cleaned. During this process, the motor 2 works, driving the end plate 201 to rotate. The crushing rod 202 is pre-threaded into the end plate 201, controlling the extension length of the crushing rod 202. The crushing rod 202, containing the crushing teeth 2021, contacts the plated sludge for crushing. At the same time, high-pressure water is introduced into the cleaning pipe 5 and sprayed out from the rotating nozzle 501. The rotating nozzle 501 rotates and washes the inner wall of the pipe. As the base 1 moves into the pipe, a preliminary flush is performed. Then, the lifting ring 105 is connected to the traction rope 1051 for easy control of the entire device. The traction rope 1051 is used to pull it out and pull it to the pipe opening for cleaning again. During this process, the cleaning pipe 5 and the rotating nozzle 501 will wash off the sludge adhering to the inner wall of the pipe. This operation is repeated several times to clean the sludge.

[0029] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
