Description

Technical Field

[0001] The utility model relates to the technical field of pipeline desilting, in particular to a device for desilting the interior of a water conservancy pipeline. Background Art

[0002] Pipeline desilting is a key measure to maintain urban infrastructure. It aims to remove sediment, silt and foreign matter in pipes to ensure that the drainage system is unobstructed. This process is crucial to preventing floods, reducing pollution and extending the service life of pipes. Effective pipeline desilting can avoid sewage overflow, odor spread and potential health risks, and ensure the quality of life of residents and environmental safety.

[0003] Currently, the existing pipeline dredging device usually consists of multiple inner wall hanging plates and high-pressure nozzles. In order to adapt to the sizes of different pipe diameters, the existing device uses a spring and a multi-link method as an adjustment mechanism for adjusting the distance between the inner wall scraper and the device body. This mechanism ensures that the inner wall scraper can fit closely to the inner wall of the pipeline through the compression and extension of the spring. However, after being compressed and stretched for a long time, the spring may produce plastic deformation, resulting in its elasticity weakening or failure, thereby making it impossible to accurately adjust the position of the inner wall scraper. In view of this, we provide a water conservancy pipeline internal dredging device. Utility Model Content

[0006] As mentioned above, the edge limiting groove is located on one side of the outer wall of the movable base, and the movable base is slidably connected to one side of the inner part of the body through the edge limiting groove.

[0007] As mentioned above, one side of the outer wall of the movable base passes through one end of the inner part of the edge limiting groove, and the inner end of the edge limiting groove is slidably connected to the outer wall of one side of the movable base.

[0008] On the above, one outer wall of one side of the movable base is connected through the inside of the central limiting groove, and one end inside the central limiting groove is slidably connected to one side of the outer wall of the movable base. The central limiting groove and the edge limiting groove are respectively located on both sides of the outer wall of the movable base, and the movable base is slidably connected to one side inside the machine body through the central limiting groove and the edge limiting groove.

[0009] On the above, the multi-section double-threaded lead screw is located at the center inside the central limiting groove, and one outer wall of the multi-section double-threaded lead screw is simultaneously located on one side inside the movable base. One outer wall of the multi-section double-threaded lead screw is closely attached to one side of the outer wall of the movable base, and one outer wall of the multi-section double-threaded lead screw is rotationally connected to one side of the outer wall of the movable base through a thread.

[0010] On the above, one side inside the movable base is rotationally connected with an inclined connecting rod through a rotating shaft, and the top end inside the inclined connecting rod is simultaneously rotationally connected with a top support. The inclined connecting rods are symmetrically distributed between the machine body and the inner wall scraper.

[0011] On the above, the top support is located on one side of the top of the movable base, and the outer wall of the top end of the top support is fixedly connected to one side of the plane of the inner wall scraper.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-5As shown in the figure, the utility model provides a technical solution: a device for dredging the inside of a water conservancy pipeline, including a machine body 1 and a high-pressure nozzle 101. The high-pressure nozzle 101 is located at the center inside the machine body 1, and both sides of the outer wall of the high-pressure nozzle 101 are fixedly connected to the center inside the machine body 1. A plurality of central limiting grooves 2 are opened at the inner edge of the machine body 1, and a plurality of groups of edge limiting grooves 201 are simultaneously opened on both sides inside the machine body 1. The edge limiting grooves 201 are located on the outer sides of both sides of the central limiting grooves 2. A plurality of movable bases 202 are slidably connected to both sides inside the central limiting grooves 2. A multi-section double-threaded screw rod 3 is rotatably connected to the center inside the machine body 1, and a plurality of adjusting knobs 301 are simultaneously rotatably connected to the outer wall of one side of the machine body 1. One end of the outer wall of the multi-section double-threaded screw rod 3 penetrates and is connected to the inner wall of one side of the machine body 1, and one end of the outer wall of the multi-section double-threaded screw rod 3 penetrates one side inside the machine body 1 and is fixedly connected to the center of the outer wall of the adjusting knob 301. A plurality of inner wall scrapers 302 are movably connected to the outer wall of the machine body 1 through the movable bases 202 and the multi-section double-threaded screw rod 3.

[0024] By respectively penetrating both sides of the outer wall of the movable base 202 into one end inside the edge limiting groove 201 and the central limiting groove 2, and respectively slidably connecting both sides of the outer wall of the movable base 202 to one end inside the edge limiting groove 201 and the central limiting groove 2, the central limiting groove 2 and the edge limiting groove 201 cooperate with each other to jointly limit the movement track of the movable base 202. When it is necessary to adjust the distance between the inner wall scraper 302 and the machine body 1, rotate the adjusting knob 301 to drive the multi-section double-threaded screw rod 3 to rotate on one side inside the machine body 1. As the multi-section double-threaded screw rod 3 rotates, the multi-section double-threaded screw rod 3 cooperates with the central limiting groove 2 through the external thread on the outer wall, and pushes a plurality of movable bases 202 to simultaneously move towards the center inside the edge limiting groove 201. Along with the movement of the movable base 202, the movable base 202, the inclined connecting rod 303 and the top support 304 are closely matched, and the inner wall scraper 302 is pushed to gradually move away from the outer wall of the machine body 1 following the rotation of the multi-section double-threaded screw rod 3. Furthermore, through the cooperation of the multi-section double-threaded screw rod 3 and the inclined connecting rod 303, it is avoided that as the use time of the device increases, the spring gradually produces plastic deformation, resulting in its inability to accurately adjust the position of the inner wall scraper. At the same time, the distance between the inner wall scraper 302 and the machine body 1 can also be precisely adjusted, so that the adjusted inner wall scraper 302 closely fits the inner wall of the pipeline.

[0025] As Figures 1-3 shown, the edge limiting groove 201 is located on one side of the outer wall of the movable base 202, and the movable base 202 is slidably connected to one side inside the machine body 1 through the edge limiting groove 201. One end of the outer wall of the movable base 202 penetrates one end inside the edge limiting groove 201, and one end inside the edge limiting groove 201 is slidably connected to one side outer wall of the movable base 202. By one end of the outer wall of the movable base 202 penetrating one end inside the edge limiting groove 201, the movement track of the movable base 202 is restricted.

[0026] One outer wall of one side of the movable base 202 is connected through one side inside the central limiting groove 2, and one end inside the central limiting groove 2 is slidably connected with one side outer wall of the movable base 202. The central limiting groove 2 and the edge limiting groove 201 are respectively located on both sides of the outer wall of the movable base 202, and the movable base 202 is slidably connected with one side inside the body 1 through the central limiting groove 2 and the edge limiting groove 201. Pass one outer wall of the movable base 202 away from the edge limiting groove 201 through one side inside the central limiting groove 2, and make one side outer wall of the movable base 202 slidably connected with one side inside the central limiting groove 2, so that the central limiting groove 2 further restricts the movement track of the movable base 202, so that the movable base 202 can move more smoothly along the inner walls of the central limiting groove 2 and the edge limiting groove 201 during the movement process.

[0027] Such as Figure 1 、 Figure 4 And Figure 5 As shown, the multi-section double-threaded screw rod 3 is located at the center inside the central limiting groove 2, and one outer wall of one side of the multi-section double-threaded screw rod 3 is simultaneously located inside one side of the movable base 202. One outer wall of one side of the multi-section double-threaded screw rod 3 is in close contact with one side outer wall of the movable base 202, and one outer wall of one side of the multi-section double-threaded screw rod 3 is rotationally connected with one side outer wall of the movable base 202 through a thread. By making one outer wall of one side of the multi-section double-threaded screw rod 3 in close contact with the movable base 202, and making the thread provided on one outer wall of the multi-section double-threaded screw rod 3 tightly meshed with the thread on one side of the movable base 202, when the multi-section double-threaded screw rod 3 rotates, it can cooperate with the central limiting groove 2 and the edge limiting groove 201 through the outer wall thread to push the movable base 202 to move horizontally along the inner walls of the central limiting groove 2 and the edge limiting groove 201.

[0028] The inclined connecting rods 303 are symmetrically distributed between the body 1 and the inner wall scraper 302. The top support 304 is located on one side of the top of the movable base 202, and the top outer wall of the top support 304 is fixedly connected with one plane side of the inner wall scraper 302. Rotationally connect the movable base 202 with the top support 304 through the inclined connecting rod 303, and distribute the inclined connecting rod 303, the movable base 202 and the top support 304 symmetrically between the body 1 and the inner wall scraper 302. When the multi-section double-threaded screw rod 3 drives a plurality of movable bases 202 to move along the central limiting groove 2 towards the thread symmetry through the outer wall thread respectively, when the plurality of inclined connecting rods 303 drive the inclined connecting rods 303 to move together, the plurality of opposite inclined connecting rods 303 cooperate together to push the top support 304 and the inner wall scraper 302 to move smoothly away from the body 1, thereby realizing precise adjustment of the distance between the inner wall scraper 302 and the body 1.

[0029] Working principle: By passing through one end inside the edge limiting groove 201 on the outer wall of one side of the movable base 202, the movement trajectory of the movable base 202 is restricted. The outer wall of the side of the movable base 202 away from the edge limiting groove 201 passes through one side inside the central limiting groove 2, and the outer wall of one side of the movable base 202 is slidably connected to one side inside the central limiting groove 2, so that the central limiting groove 2 further restricts the movement trajectory of the movable base 202, enabling the movable base 202 to move more smoothly along the inner walls of the central limiting groove 2 and the edge limiting groove 201 during the movement process. By closely fitting one side of the outer wall of the multi-section double-threaded screw rod 3 with the movable base 202, and making the threads provided on the outer wall of the multi-section double-threaded screw rod 3 tightly engage with the threads on one side of the movable base 202, when the multi-section double-threaded screw rod 3 rotates, it can cooperate with the outer wall threads and the central limiting groove 2 and the edge limiting groove 201 to push the movable base 202 to move horizontally along the inner walls of the central limiting groove 2 and the edge limiting groove 201. The movable base 202 is rotatably connected to the top support 304 through the inclined connecting rod 303, and the inclined connecting rod 303, the movable base 202 and the top support 304 are symmetrically distributed between the machine body 1 and the inner wall scraper 302. When the multi-section double-threaded screw rod 3 drives multiple movable bases 202 to move along the central limiting groove 2 towards the symmetric position of the threads through the outer wall threads respectively, when the multiple movable bases 202 drive the inclined connecting rod 303 to move together, the multiple opposite inclined connecting rods 303 cooperate together to push the top support 304 and the inner wall scraper 302 to move smoothly towards the side away from the machine body 1, realizing precise adjustment of the distance between the inner wall scraper 302 and the machine body 1.
