Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline dredging technology, and in particular to a high-pressure water jet dredging device. Background Technology
[0002] Municipal drainage pipelines, as a crucial component of urban infrastructure, bear the critical responsibility of collecting and transporting rainwater and domestic sewage. Their operational status directly impacts urban drainage safety and environmental sanitation. If drainage pipelines become clogged due to long-term accumulation of debris, cement and sand sediment from construction sites, and other reasons, and are not promptly dredged and maintained, the pipeline's drainage capacity will significantly decrease. This can lead to sewage overflowing onto roads, polluting the surrounding environment, and even causing localized urban flooding, severely impacting traffic and residents' daily lives, and threatening public safety. Pipeline dredging, which involves using dredging equipment to remove silt and other waste from pipelines, aims to maintain long-term unobstructed flow and prevent urban flooding. Essentially, it involves clearing blockages and maintaining normal water flow within the pipelines, making it an indispensable and crucial aspect of municipal engineering.
[0003] Existing pipeline dredging equipment typically uses high-pressure water jets to disperse and dilute internal sludge, facilitating thorough cleaning via suction pipes. To minimize blind spots, the ring seat connecting the nozzle is usually rotatable, and the nozzle is typically angled backward to utilize the propulsive force of the water flow, with an angle relative to the tangent to provide rotational power. However, in current technology, the impact efficiency of a single-ring nozzle is low. To ensure impact effectiveness, the rotation speed of the ring seat is limited. Consequently, the rotation of the ring seat generates a reaction force on the dredging equipment, causing the connected high-pressure water pipeline to tend to twist. This can easily lead to pipeline twisting, especially in long pipelines. Furthermore, existing technology is prone to deviation during water jetting, resulting in uneven spray direction and incomplete cleaning, indicating room for further improvement.

[0009] According to the high-pressure water jet dredging device, the ends of the multiple connecting rods away from the sliding sleeve are rotatably connected to the corresponding support diagonal rods.
[0010] According to the high-pressure water jet dredging device, the spring limiting sleeve and the sliding sleeve are both provided with spring grooves on the side near the supporting spring, and both ends of the supporting spring are respectively fixedly connected to the spring limiting sleeve and the sliding sleeve.
[0011] According to the high-pressure water jet dredging device, a water supply ring is fixedly connected to the outer side of the central tube at a position corresponding to the first water jet ring seat and the second water jet ring seat, and the inner sides of the first water jet ring seat and the second water jet ring seat are rotatably connected to the corresponding water supply ring.
[0012] According to the high-pressure water jet dredging device, the spray direction of the high-pressure nozzle of the first water jet ring seat is set at a 30-degree angle clockwise relative to the tangent direction of the first water jet ring seat, and the spray direction of the high-pressure nozzle of the second water jet ring seat is opposite to the spray direction of the first water jet ring seat.
[0013] According to the high-pressure water jet dredging device, the high-pressure nozzles of the first and second water jet ring seats are offset to one side of the high-pressure pipeline in the direction of their corresponding axes.

[0026] Reference Figure 1-4 This utility model provides a high-pressure water jet dredging device, including a base 1. A pipe connector 2 is provided at one end of the base 1. A high-pressure pipe 3 is fixedly connected to the end of the pipe connector 2 away from the base 1. A connecting seat 4 is provided on the outer side of the middle of the base 1. Multiple supporting inclined rods 11 are rotatably connected at equal intervals to the outer side of the connecting seat 4. Each of the multiple supporting inclined rods 11 is rotatably connected to a pipe wall support seat 13 at the end away from the connecting seat 4. Pipe wall pulleys 14 are rotatably connected to both ends of the multiple pipe wall support seats 13. A spring limiting sleeve 7 is fixedly connected to the outer side of the base 1 near the pipe connector 2. A sliding sleeve 5 is provided on the outer side of the base 1 between the connecting seat 4 and the spring limiting sleeve 7. The outer side of the sliding sleeve 5 is connected to the supporting inclined rods 11. 1. A connecting rod 12 is rotatably connected to each corresponding position. The end of the multiple connecting rods 12 away from the sliding sleeve 5 is rotatably connected to the corresponding support inclined rod 11. A support spring 6 is provided on the outside of the base 1 between the sliding sleeve 5 and the spring limiting sleeve 7. The spring limiting sleeve 7 and the sliding sleeve 5 are both provided with spring grooves on the side close to the support spring 6. Both ends of the support spring 6 are fixedly connected to the spring limiting sleeve 7 and the sliding sleeve 5 respectively. Under the action of the support spring 6, the sliding sleeve 5 can be moved, thereby driving the connecting rod 12 to support the support inclined rod 11. By using the spring support force to push the support inclined rod 11 outward, the base 1 can be kept as centered as possible in the pipeline, avoiding the situation of incomplete cleaning after eccentricity.
[0027] A first water spray ring seat 8 and a second water spray ring seat 10 are rotatably connected to the outer side of the base 1, away from the high-pressure pipe 3. Planetary gear mechanisms 9 are provided inside the base 1 at positions corresponding to the first water spray ring seat 8 and the second water spray ring seat 10. A central tube 16 is located at the center of the base 1. A water supply ring is fixedly connected to the outer side of the central tube 16 at positions corresponding to the first water spray ring seat 8 and the second water spray ring seat 10. The inner sides of the first water spray ring seat 8 and the second water spray ring seat 10 are rotatably connected to their respective water supply rings. Multiple high-pressure nozzles 15 are provided on the outer sides of both the first water spray ring seat 8 and the second water spray ring seat 10. The spray direction of the high-pressure nozzles 15 on the first water spray ring seat 8 is clockwise relative to the tangential direction of the first water spray ring seat 8. The needle is set with a 30-degree included angle, and the spray direction of the high-pressure nozzle 15 of the second water spray ring seat 10 is opposite to that of the first water spray ring seat 8. The spray directions of the high-pressure nozzles 15 of the first water spray ring seat 8 and the second water spray ring seat 10 are offset to one side of the high-pressure pipe 3. The first water spray ring seat 8 and the second water spray ring seat 10 can greatly improve the density of the water spray. With the two linked planetary gear mechanisms 9, a coaxial reverse linkage can be formed. By setting high-pressure nozzles 15 with opposite spray angles on the two water spray ring seats, when the two water spray ring seats spray water, not only can the silt be flushed from two directions, but the torque generated by the two water spray ring seats can also cancel each other out, avoiding the torsional tendency of the pipe when spraying water.
[0028] Both planetary gear mechanisms 9 include an internal gear ring, a central gear, three planetary gears, and a planet carrier corresponding to each planetary gear. The first water spray ring seat 8 is fixedly connected to the side of the internal gear ring of the corresponding planetary gear mechanism 9 near the high-pressure pipe 3. The second water spray ring seat 10 is fixedly connected to the side of the central gear of the corresponding planetary gear mechanism 9 away from the high-pressure pipe 3. Three fixing pins 17 are fixedly connected to the inner side of the base 1 at the position corresponding to the planetary gears. The base 1 is fixedly connected to the two planet carriers through the three fixing pins 17. By fixing the two planet carriers, the two planetary gear mechanisms 9 can move synchronously, forming a coaxial reverse motion mechanism. This allows the two water spray ring seats, which are respectively connected to the internal gear ring and the central gear, to move coaxially in opposite directions. The end of the central tube 16 near the high-pressure pipe 3 is fixedly connected to the pipe connector 2. The outer side of the central tube 16 passes through the center of the two central gears and is rotatably connected to the central gears.
[0029] Working principle: When in use, the sliding sleeve 5 moves under the action of the supporting spring 6, thereby driving the connecting rod 12 to support the supporting inclined rod 11. By using the spring support force to push the supporting inclined rod 11 outward, the base 1 can be kept in the center of the pipe as much as possible, avoiding incomplete cleaning due to eccentricity. The first water spray ring seat 8 and the second water spray ring seat 10 set on the base 1 can greatly improve the density of the water spray. With the two linked planetary gear mechanisms 9, a coaxial reverse linkage can be formed. Furthermore, by setting high-pressure nozzles 15 with opposite spray angles on the two water spray ring seats, when the two water spray ring seats spray water, not only can the sludge be flushed from two directions, but the torque generated by the two water spray ring seats can also cancel each other out, avoiding the torsional tendency of the pipe during water spraying.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
