Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline dredging technology, specifically a municipal engineering pipeline drainage dredging device. Background Technology
[0002] Municipal engineering pipelines are a crucial part of urban infrastructure, characterized by diverse functions, abundant materials, and stringent construction requirements. They encompass water supply, drainage, gas, electricity, and communications, utilizing a variety of materials such as plastics, metals, and reinforced concrete to meet different environments and needs. Drainage pipelines, in particular, require regular dredging because blockages affect drainage efficiency, leading to sewage backflow, environmental pollution, and other problems. Regular dredging removes sediment and foreign objects from the pipes, ensuring the normal operation of the drainage system and maintaining urban environmental sanitation and residents' quality of life.
[0003] However, drainage pipes have complex paths and various types of blockages inside. When faced with mixed blockages such as tree roots, concrete residue, and tangled plastic sheeting, conventional flushing is difficult to completely remove them, mechanical dredging equipment is difficult to maneuver flexibly, and manual cleaning is inefficient. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a municipal engineering pipeline drainage dredging device that can be used to clear mixed blockages such as tree roots, concrete residue, and tangled plastic sheeting.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a municipal engineering pipeline drainage dredging device, including a protective pipe, an electric cable installed inside the protective pipe, a drive chamber connected to the electric cable at the end of the protective pipe, a drilling component installed inside the drive chamber, and several rotating bases evenly arranged outside the drive chamber, with hook components rotatably connected to the rotating bases.
[0006] Furthermore, the drilling assembly includes a drive motor housed within the drive chamber, with the rear end of the drive motor connected to a power cable, and a detachable feed drill bit connected to the drive shaft of the drive motor, the feed drill bit being mounted at the front end of the drive chamber.
[0007] Furthermore, the hook assembly includes a rotating rod, the front end of which is rotatably mounted on a rotating base, and the end of which is rotatably connected to a main hook. The main hook has a downward and forward-curved configuration. A driven hook is provided on the top surface of the rotating rod, and the end of the driven hook is bent backward. Several auxiliary hooks are evenly arranged on both sides of the rotating rod.
[0008] Furthermore, a telescopic rod is provided at the front end of the rotating rod. The telescopic rod is slidably installed inside the rotating rod, and the front end of the telescopic rod is rotatably installed on the rotating base to replace the rotating connection of the rotating rod. A limit block is provided on the top surface of the telescopic rod, and a limit groove for the sliding of the limit block is opened on the top surface of the rotating rod. The telescopic rod and the rotating rod are fixed by bolts and nuts. Fixing holes I for bolts are opened on both sides of the front end of the telescopic rod, and several fixing holes II for bolts are evenly opened on both sides of the rotating rod.
[0009] Furthermore, the auxiliary hook is rotatably mounted on the rotating rod, and a T-shaped rotating column is provided on the bottom surface of the auxiliary hook. The long end of the T-shaped rotating column is set as an arc block with a central angle of 45°. A rotating groove is provided on the rotating rod for the T-shaped rotating column to rotate, and the rotating groove allows the T-shaped rotating column to rotate within the range of 45° clockwise to 90° counterclockwise.
[0010] Furthermore, several forward-facing assist hooks are fixedly installed on the bottom surface of the telescopic rod, and a sliding groove for the assist hooks to slide is opened on the bottom surface of the rotating rod.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] By directly connecting the drive motor and the drill bit through a drive chamber, the power transmission path is shortened, improving dredging efficiency. The detachable design of the drill bit facilitates replacement with different specifications, adapting to complex blockages in the pipe. A hook assembly is mounted outside the drive chamber; as the device drills into the blockage, its backward pull causes the rotating rod to rotate forward. The main hook, driven hook, and auxiliary hook work together, transmitting torque through the rotating rod to create a "grab-pull-break" linkage mechanism, further clearing the pipe. An adjustable hook assembly length, achieved through bolts, nuts, and fixing holes, allows for adaptation to different pipe diameters, expanding the device's applicability and reducing replacement frequency. A rotating auxiliary hook, with its T-shaped rotating column and groove, restricts the hook's rotation angle, allowing it to adapt to the pipe's inner wall shape and preventing jamming. An assist hook on the bottom of the telescopic rod extends from the groove, increasing contact points with the blockage and improving dredging success rate. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] like Figures 1 to 6 As shown, a municipal engineering pipeline drainage dredging device includes a protective pipe 1. The protective pipe 1 is characterized in that a power cable 2 is installed inside the protective pipe 1, a drive chamber 3 connected to the power cable 2 is installed at the end of the protective pipe 1, a drilling component 4 is installed inside the drive chamber 3, and a plurality of rotating bases 301 are evenly arranged on the outside of the drive chamber 3. A hook component 5 is rotatably connected to the rotating base 301.
[0022] like Figure 1 As shown, the main improvement of this utility model is that it can be used to clear mixed blockages such as tree roots, concrete residue, and tangled plastic sheeting. Figures 1 to 6As shown, the municipal engineering pipeline drainage dredging device of this utility model, when in use, first select a suitable push drill bit 402 according to the condition inside the pipeline and install it at the front end of the drive chamber 3. Then, remove the bolt and nut at the fixing hole 508. Adjust the position of the telescopic rod 505 according to the width of the pipeline. After the position is adjusted properly, use bolts to pass through the fixing hole 508 and the fixing hole 509, and fix the rotating rod 501 and the telescopic rod 505 together with the help of the nut to complete the preparation work. Then, put the device into the pipeline and push the protective tube 1 inward to make the device move into the pipeline. The device moves forward and, upon reaching the blockage, controls the drive motor 401 via the power cable 2, thereby driving the drilling bit 402 to drill through the blockage. After the drilling bit 402 passes through the blockage, it continues to push forward a distance and then pulls the device back. At this time, the rotating rod 501 will rotate forward, and the main hook 502, driven hook 503, auxiliary hook 504, and assisting hook 512 will unfold. Under the torque transmitted by the rotating rod 501, a "grab-hook-pull-break" linkage mechanism is formed, which breaks the blockage structure and pulls part of the blockage back, thus clearing the pipe.
[0023] like Figures 1 to 3 As shown, the drilling assembly 4 includes a drive motor 401 disposed in the drive chamber 3. The rear end of the drive motor 401 is connected to the power cable 2. A detachable feed drill bit 402 is connected to the drive shaft of the drive motor 401. The feed drill bit 402 is installed at the front end of the drive chamber 3.
[0024] Specifically, by setting up the drilling assembly 4, mixed blockages can be drilled to destroy their structure and make them easier to clean. By setting up the drive chamber 3 to directly connect the drive motor 401 and the feed drill bit 402, the power transmission path can be shortened and the unblocking efficiency can be improved. At the same time, the detachable design of the feed drill bit 402 makes it easy to replace drill bits of different specifications to adapt to complex blockages in the pipeline.
[0025] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the hook assembly 5 includes a rotating rod 501. The front end of the rotating rod 501 is rotatably mounted on the rotating base 301, and the end of the rotating rod 501 is rotatably connected to a main hook 502. The main hook 502 has a downward and forward-curved configuration. A driven hook 503 is provided on the top surface of the rotating rod 501. The end of the driven hook 503 is bent backward. Several auxiliary hooks 504 are evenly arranged on both sides of the rotating rod 501.
[0026] Specifically, as the device moves toward the blockage, the downward and forward-bending main hook 502 and the backward-bending driven hook 503 prevent the device from getting tangled in the hooks, minimizing the resistance to the device's movement. After the device passes through the blockage, as the device is pulled backward, the rotating rod 501 will rotate forward. At this time, with the cooperation of the main hook 502, driven hook 503 and auxiliary hook 504, torque is transmitted through the rotating rod 501, forming a "grab-hook-break" linkage mechanism to unclog the pipe.
[0027] like Figure 4 and Figure 5 As shown, a telescopic rod 505 is provided at the front end of the rotating rod 501. The telescopic rod 505 is slidably disposed inside the rotating rod 501. The front end of the telescopic rod 505 is rotatably disposed on the rotating base 301 to replace the rotating connection of the rotating rod 501. A limit block 506 is provided on the top surface of the telescopic rod 505. A limit groove 507 for sliding of the limit block 506 is provided on the top surface of the rotating rod 501. The telescopic rod 505 and the rotating rod 501 are fixed by bolts and nuts. Several fixing holes 508 for bolts are evenly provided on both sides of the rotating rod 501. Fixing holes 509 for bolts are provided on both sides of the front end of the telescopic rod 505.
[0028] Specifically, by setting the telescopic rod 505 to slide within the rotating rod 501, the length of the hook assembly 5 is adjustable, thus adapting to different pipe diameters and expanding the applicability of the device. In this case, the front end of the telescopic rod 505 is closer to the rotating base 301 than the rotating rod 501; therefore, the telescopic rod 505 is chosen for rotation, ensuring smooth extension and retraction. With the cooperation of the limiting block 506 and the limiting groove 507, the extension and retraction distance of the telescopic rod 505 can be limited, preventing it from falling off. Simultaneously, with the cooperation of bolts, nuts, and fixing holes 508 and 509, the telescopic rod 505 and the rotating rod 501 can be fixed together, ensuring the stability of the device.
[0029] like Figure 5 and Figure 6 As shown, the auxiliary hook 504 is rotatably mounted on the rotating rod 501. The bottom surface of the auxiliary hook 504 is provided with a T-shaped rotating column 510. The long end of the T-shaped rotating column 510 is set as an arc block with a central angle of 45°. The rotating rod 501 is provided with a rotating groove 511 for the rotation of the T-shaped rotating column 510. The rotating groove 511 allows the T-shaped rotating column 510 to rotate within the range of 45° clockwise to 90° counterclockwise.
[0030] Specifically, by setting a rotating auxiliary hook 504, the auxiliary hook 504 can adapt to the shape of the inner wall of the pipe to avoid jamming; and the 45° arc block cooperates with the rotating groove 511, so that the rotation angle of the T-shaped rotating column 510 is limited to between 45° clockwise and 90° counterclockwise, while the angle of the auxiliary hook 504 will be limited to between 0° and -90°, ensuring that after the rotating rod 501 rotates, the bent end of the auxiliary hook 504 can contact the blockage, thereby improving the pulling effect of the device.
[0031] like Figure 4 and Figure 5 As shown, several forward-facing assist hooks 512 are fixedly installed on the bottom surface of the telescopic rod 505, and a groove 513 for sliding the assist hooks 512 is opened on the bottom surface of the rotating rod 501.
[0032] Specifically, by setting an assist hook 512 on the bottom surface of the telescopic rod 505, the assist hook 512 will also extend from the slide groove 513 after the telescopic rod 505 is extended or retracted. These assist hooks 512 can increase the contact points between the device and the blockage, thereby improving the success rate of unblocking during the pulling process.
[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
