Abstract
Description
Technical Field
[0001] This application relates to the technical field of pipe dredging, and in particular to a device for dredging urban drainage pipes. Background Technology
[0002] Sewer pipes bring convenience to our lives. We can directly pour our wastewater into the pool and then transport it to the sewage treatment plant for treatment through the pipes. However, in reality, various reasons can cause the pipes to become blocked, requiring manual unblocking.
[0003] Regarding the aforementioned technologies, the applicant believes that it is difficult to manually unclog blocked pipes, and therefore a dredging device that facilitates the unblocking of drainage pipes is needed. Utility Model Content
[0004] To improve the convenience of pipe dredging, this application provides a device for dredging urban drainage pipes.
[0005] The urban drainage pipe dredging device provided in this application adopts the following technical solution:
[0006] A device for dredging urban drainage pipes includes a mobile base with rollers at the bottom and a dredging structure at the end of the mobile base. The dredging structure includes a dredging drill bit driven to rotate by a drive motor and a plurality of auxiliary drill rods offset from the dredging drill bit. The auxiliary drill rods are movably connected to the mobile base through a movable structure. The movable structure includes a rotating plate fixed to the auxiliary drill rods and a connecting plate fixed to the mobile base. The rotating plate is rotatably connected to the connecting plate, and the rotating plate and the connecting plate are positioned by fixing bolts.
[0007] By adopting the above technical solution, a self-rotating dredging drill bit driven by a drive motor, along with several auxiliary drill rods, can improve the cleaning effect on blockages in pipelines. The auxiliary drill rods can move relative to each other on the moving seat through the cooperation of the rotating plate and the connecting plate, which makes it easy to change the extension direction of the auxiliary drill rods. On the one hand, the auxiliary drill rods can converge at the dredging drill bit to increase the local pressure on solidified blockages; on the other hand, the auxiliary drill rods can extend in their respective directions to increase the coverage area of dredging and help improve the dredging effect on pipelines.
[0008] Preferably, the dredging drill bit is rotatably connected to the middle of the mobile carriage, and the auxiliary drill rod is circumferentially arranged at the corner of the mobile carriage and can rotate longitudinally; the ends of the longitudinally opposite auxiliary drill rods can approach each other and be connected by a fixed structure.
[0009] By adopting the above technical solution, the dredging drill bit located in the middle plays the main role of rotating and dredging, while the auxiliary drill rod located at the corner is used to expand the dredging range. By connecting the two longitudinal auxiliary drill rods to each other, the dredging area in the middle of the moving seat can be increased, and when the longitudinal auxiliary drill rods extend in the opposite direction, the outer dredging range can be increased.
[0010] Preferably, the fixing structure includes a fixing plate and an abutment plate respectively rotatably connected to the side of the corresponding longitudinal auxiliary drill rod that are close to each other, and a locking bolt. The fixing plate and the abutment plate can extend vertically and abut against each other in the lateral direction, and the locking bolt passes through and is fixed to the fixing plate and the abutment plate.
[0011] By adopting the above technical solution, the horizontally abutting fixed plate and abutting plate provide space for fixing the locking bolts. The corresponding fixed plate and abutting plate can be fixed from both sides of the moving seat, avoiding the problem of the auxiliary drill rod obstructing the fixing. After fixing the rotating plate and connecting plate with the fixing bolts, the stability of the longitudinally opposite auxiliary drill rods extending towards each other is further improved by the cooperation of the fixed plate and abutting plate, thereby improving the working stability of the device under the corresponding dredging requirements.
[0012] Preferably, the auxiliary drill rod has a receiving groove for accommodating the corresponding fixing plate and abutment plate, and the fixing plate and abutment plate can be fixed in the receiving groove by positioning bolts.
[0013] By adopting the above technical solution, when the auxiliary drill rod rotates to extend in the opposite direction, the fixing plate and the abutment plate can be stored and fixed in the receiving groove to avoid interfering with the dredging operation.
[0014] Preferably, the dredging structure further includes a deformable scraper fixed above the mobile seat; a support plate extends and is fixed on the mobile seat, and the support plate extends forward toward the mobile seat to form a mounting plate, and the scraper is fixed on the mounting plate.
[0015] By adopting the above technical solution, the support plate supports the scraper against the inner wall of the pipe. The deformable property allows the scraper to closely fit and scrape away silt and other debris from the upper inner wall of the pipe, thus assisting in dredging.
[0016] Preferably, the upper part of the scraper is arc-shaped to fit the inner wall of the pipe.
[0017] Preferably, the side wall of the support plate is provided with triangular reinforcing ribs that are fixed at the bottom to the movable seat.
[0018] Preferably, the ends of both the dredging drill bit and the auxiliary drill rod are tapered.
[0019] By adopting the above technical solution, the conical end can increase the contact pressure, which is beneficial for dredging and clearing.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. A self-rotating dredging drill bit driven by a drive motor, along with several auxiliary drill rods, can improve the cleaning effect on blockages in pipelines. The auxiliary drill rods can move relative to each other on the moving seat through the cooperation of a rotating plate and a connecting plate, making it easy to change the extension direction of the auxiliary drill rods. On the one hand, the auxiliary drill rods can converge at the dredging drill bit to increase local pressure on solidified blockages; on the other hand, the auxiliary drill rods can extend in their respective directions to increase the coverage area of dredging and help improve the dredging effect on pipelines.
[0022] 2. The dredging drill bit located in the middle plays the main role in rotating and dredging, while the auxiliary drill rod located at the corner is used to expand the dredging range. The conical ends of the dredging drill bit and the auxiliary drill rod can increase the contact pressure, which is conducive to dredging and unblocking. By connecting the two longitudinal auxiliary drill rods to each other, the dredging area in the middle of the moving seat can be increased, and when the longitudinal auxiliary drill rods extend in the opposite direction, the outer dredging range can be increased.
[0023] 3. When the auxiliary drill rod rotates to extend in the opposite direction, the fixing plate and the abutment plate can be stored and fixed in the receiving groove to avoid interfering with the dredging operation. Attached Figure Description

The locking bolt 43 passes through and is fixed to the fixing plate 41 and the abutment plate 42. The lateral abutment of the fixing plate 41 and the abutment plate 42 provides space for the fixing of the locking bolt 43. The corresponding fixing plate 41 and the abutment plate 42 can be fixed from both sides of the moving seat 1 to avoid the problem of the auxiliary drill rod 22 obstructing the fixing. After fixing the rotating plate 31 and the connecting plate 32 with the fixing bolt 33, the stability of the longitudinally opposite auxiliary drill rod 22 extending towards each other is further improved by the cooperation of the fixing plate 41 and the abutment plate 42, thereby improving the working stability of the device under the corresponding dredging requirements.
