Description

Technical Field

[0001] This utility model relates to the field of drainage engineering technology, and in particular to a drainage pipe dredging device. Background Technology

[0002] Drainage pipes refer to the system of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater, including main pipes, branch pipes and pipes leading to treatment plants. Regardless of whether they are built on streets or anywhere else, any pipe that serves the purpose of drainage should be considered a drainage pipe.

[0003] In the prior art, patent document CN221236133U discloses a drainage pipe unblocking tool, including a handle with a rope at the bottom, a mounting block at the other end of the rope, and a unblocking component on the mounting block for unblocking debris in the pipe. A fixing block is located at the bottom of the mounting block, and a rotating shaft is rotatably mounted on the bottom of the fixing block. A drill bit is located at the other end of the rotating shaft. A first motor is embedded in the fixing block and is connected to the rotating shaft for transmission. In this invention, the first motor enables the drill bit to rotate at high speed, facilitating the drilling of blockages in the pipe. The weight of the fixing block then allows the blockage to pass through. Activating the second motor causes a nut to move downwards, opening multiple support plates. Finally, pulling the handle upwards hooks out the blockage from the support plates, achieving efficient pipe unblocking.

[0004] However, the above solution still has some shortcomings in actual use: after clearing the blockage inside the pipe, the above solution adds an extra step of removing the blockage. This not only increases the workload of the staff, but also, due to the weight of the blockage, the tray holding the trash may deform during the removal process. Once the tray is deformed, it will significantly increase the risk of it getting stuck inside the pipe, causing unnecessary trouble for subsequent operations. Summary of the Invention

[0005] The purpose of this invention is to provide a drainage pipe unblocking device to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A drain pipe unblocking device includes a connecting rope, and the drain pipe unblocking device further includes: A handle, which is connected to the first end of the connecting rope; A connecting tube, which is connected to the second end of the connecting rope; A fixing mechanism includes an adjusting assembly disposed on the outer periphery of the connecting cylinder, a hinge assembly disposed on the adjusting assembly, and a limiting top plate disposed on the hinge assembly. When the limiting top plate is extended, it can fix the connecting cylinder within the drainage pipe to be dredged. The unblocking mechanism includes a drive assembly installed at the bottom of the connecting cylinder and a cleaning assembly installed on the drive assembly; When the connecting cylinder is fixed to the location to be dredged in the drainage pipe by the fixing mechanism, the driving component of the dredging mechanism drives the cleaning component to dredge the location to be dredged.

The multiple guide rods pass through the corresponding through holes of the sliding rings, and the screws are threaded into the corresponding threaded holes of the sliding rings. The hinge assembly is disposed between the two sliding rings. Both ends of the multiple guide rods are rotatably connected to a circular plate mounted on the connecting cylinder via bearings; the first end of the screw is rotatably connected to a circular plate mounted on the connecting cylinder via a bearing, the second end of the screw is connected to the power output end of the motor, and the motor is fixed to the connecting cylinder via the circular plate.

[0008] In one possible implementation, the number of hinge components is multiple sets, and the multiple sets of hinge components are distributed at intervals between the two sliding rings. Each set of hinge components includes two hinge rods arranged along the axial direction of the connecting cylinder. The opposite ends of the two hinge rods are hinged to the two sliding rings through hinge seats, and the opposite ends of the two hinge rods are hinged to the limiting top plate through connecting rods.

[0012] In one possible implementation, the handle is provided with a switch for controlling the fixing mechanism and the unblocking mechanism.

[0013] The beneficial effects of the technical solution provided by this utility model include at least the following: This technical solution uses a fixing mechanism to secure the connecting cylinder to the location to be dredged within the drainage pipe. Combined with the dredging mechanism, it efficiently removes blockages and debris from the pipe. The cleared debris is then naturally discharged from the pipe outlet with the water flow, thus quickly completing the drainage pipe dredging operation. This significantly reduces the workload and labor intensity for workers. Simultaneously, the overall structure of the device is stable and will not deform as in existing technologies during use, ensuring it maintains normal operation within the pipe and effectively preventing obstruction of subsequent operations due to device deformation, thereby improving the reliability and continuity of the dredging work.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Figure 1 This diagram illustrates the overall structure of a drainage pipe unblocking device provided in an exemplary embodiment of the present invention. Figure 2This diagram illustrates the structure of a fixing mechanism for a drainage pipe unblocking device provided in an exemplary embodiment of the present invention. The drainage pipe unblocking device includes a connecting rope 2, a handle 3 connected to a first end of the connecting rope 2, a connecting cylinder 1 connected to a second end of the connecting rope 2, a fixing mechanism 4 including an adjusting component disposed on the outer periphery of the connecting cylinder 1, a hinge component disposed on the adjusting component, and a limiting top plate 405 disposed on the hinge component. When the limiting top plate 405 is pushed out, it can fix the connecting cylinder 1 inside the drainage pipe to be unblocked. It also includes an unblocking mechanism 5, which includes a driving component installed at the bottom of the connecting cylinder 1 and a cleaning component installed on the driving component. When the connecting cylinder 1 is fixed to the unblocked position inside the drainage pipe by the fixing mechanism 4, the driving component of the unblocking mechanism 5 drives the cleaning component to unblock the unblocked position.

[0024] In this embodiment, the handle 3 facilitates gripping and operation, providing an operating fulcrum for the device. The connecting cylinder 1, as a load-bearing structure, integrates the fixing mechanism 4 and the unblocking mechanism 5. The fixing mechanism 4, through the adjusting component and the hinge component, drives the limiting top plate 405 to push out, stabilizing the connecting cylinder 1 and ensuring stable position during unblocking. The driving component of the unblocking mechanism 5 drives the cleaning component to clean the blockage after the connecting cylinder 1 is fixed. All components work together to complete the pipe unblocking.

[0025] For details, please refer to Figure 2 The adjusting assembly includes: a screw 408, which is arranged axially on the outer periphery of the connecting cylinder 1; multiple guide rods 409, all arranged axially on the outer periphery of the connecting cylinder 1, with the multiple guide rods 409 and the screw 408 spaced apart; and two sliding rings 401, each fitted onto the multiple guide rods 409 and the screw 408. The multiple guide rods 409 pass through the corresponding through holes of the sliding rings 401, and the screw 408 is threaded into the corresponding threaded hole of the sliding rings 401. A hinge assembly is arranged between the two sliding rings 401. Both ends of the multiple guide rods 409 are rotatably connected to a circular plate 406 mounted on the connecting cylinder 1 via bearings. The first end of the screw 408 is rotatably connected to the circular plate 406 mounted on the connecting cylinder 1 via a bearing, and the second end of the screw 408 is connected to the power output end of a motor 407. The motor 407 is fixed to the connecting cylinder 1 via the circular plate 406.

[0026] In this embodiment, the screw 408 is driven to rotate by the motor 407, which drives the two sliding rings 401 to move axially through a threaded connection. Multiple guide rods 409 engage with the through holes of the sliding rings 401, restricting their rotation and ensuring smooth axial sliding. When the distance between the two sliding rings 401 changes, the hinge assembly can be driven to move, thereby controlling the extension or retraction of the limiting top plate 405, thus fixing and releasing the connecting cylinder 1 within the pipe.

[0027] For more details, see [link to relevant documentation]. Figure 2 The number of hinge components is multiple sets, and the multiple sets of hinge components are distributed at intervals between the two sliding rings 401. Each set of hinge components includes two hinge rods 403 arranged along the axial direction of the connecting cylinder 1. The opposite ends of the two hinge rods 403 are hinged to the two sliding rings 401 through the hinge seat 402, and the opposite ends of the two hinge rods 403 are hinged to the limiting top plate 405 through the connecting rod 404.

[0028] In this embodiment, the multiple sets of spaced hinge components ensure uniform force distribution on the connecting cylinder 1, improving its stability. Each set of two hinge rods 403 are hinged to the sliding ring 401 via a hinge seat 402, converting the axial movement of the sliding ring 401 into an angular change. The two hinge rods 403 are hinged to the limiting top plate 405 via a connecting rod 404. When the spacing between the sliding rings 401 changes, the hinge rods 403 rotate, causing the limiting top plate 405 to simultaneously extend or retract, achieving adaptive fixing for pipes of different diameters and ensuring a stable position of the connecting cylinder during unblocking. Specifically, see Figure 3 and Figure 4 The drive component includes: a mounting slot 501, which is disposed at the bottom of the connecting cylinder 1; An electro-hydraulic rod 502 is installed in the mounting groove 501; a drain plate 503 is installed on the telescopic end of the electro-hydraulic rod 502; and a motor 504 is installed on the side of the drain plate 503 away from the electro-hydraulic rod 502; wherein, a cleaning component is installed on the power output end of the motor 504.

[0029] In this embodiment, the mounting groove 501 provides a stable mounting space for the electric hydraulic rod 502. The electric hydraulic rod 502 can drive the unblocking plate 503 to extend and retract, adjust the distance between the motor 504 and the cleaning components and the blockage, and can perform lifting and sweeping at the blockage, thereby improving cleaning efficiency.

[0030] More specifically, see Figure 4 The cleaning assembly includes: a mounting plate 505, which is mounted on the power output end of the motor 504; and a plurality of cleaning ropes 506, which are evenly spaced on the side of the mounting plate 505.

[0031] In this embodiment, multiple evenly spaced sweeping ropes 506 rotate at high speed under the drive of motor 504, which can flexibly wrap around and break up various types of blockages and garbage, adapt to the irregular shape of the inner wall of the pipe, expand the sweeping range, improve the garbage removal efficiency, and ensure effective handling of different blockage situations.

[0032] It is worth mentioning that a power source is installed inside the handle 3, which supplies power to the fixing mechanism 4 and the unblocking mechanism 5 via a wire built into the connecting rope 2. A switch for controlling the fixing mechanism 4 and the unblocking mechanism 5 is also installed on the handle 3.

[0033] In this embodiment, the power source within the handle 3 can be a rechargeable battery, which is charged via a charging port on the handle 3. The concealed wiring integrated into the connecting rope 2 prevents exposed wiring from being damaged, ensuring a stable and safe power supply. Next, the working principle of a drainage pipe unblocking device involved in the embodiments of this utility model will be explained.

[0034] First, the staff holds handle 3 and uses connecting rope 2 to send connecting cylinder 1 into the drain pipe to be unclogged until it is close to the blockage. At this time, the switch on handle 3 is used to activate fixing mechanism 4. Motor 407 drives screw 408 to rotate. Under the limiting action of multiple guide rods 409, two sliding rings 401 move relative to each other along the axial direction. The movement of sliding rings 401 drives hinge rod 403 to rotate through hinge seat 402, so that the limiting top plate 405 of multiple sets of hinge components is pushed out synchronously, tightly fitting the inner wall of the pipe, and firmly fixing connecting cylinder 1 in the position to be unclogged. Secondly, the switch on the operating handle 3 starts the unblocking mechanism 5, and the electric hydraulic rod 502 in the mounting slot 501 extends and retracts, driving the unblocking plate 503 to adjust the distance between the motor 504 and the cleaning components and the blockage; then the motor 504 runs, driving the mounting plate 505 to rotate, causing the cleaning rope 506 to rotate at high speed, wrapping around and breaking up the blockage. Throughout the process, the power supply inside the handle 3 continuously supplies power to the fixing mechanism 4 and the unblocking mechanism 5 through the wire in the connecting rope 2, ensuring that all components work together. The garbage processed by the cleaning component is discharged from the pipe outlet with the water flow. After the unblocking is completed, the switch on the handle 3 is reversed to retract the limit plate 405, and then the device is taken out of the pipe through the connecting rope 2.

[0035] In summary, this technical solution uses a fixing mechanism to secure the connecting cylinder to the location to be dredged within the drainage pipe. Combined with the dredging mechanism, it efficiently removes blockages and debris from the pipe. The cleared debris is then naturally discharged from the pipe outlet with the water flow, thus quickly completing the drainage pipe dredging operation. This significantly reduces the workload and labor intensity for workers. Furthermore, the overall structure of the device is stable and will not deform as in existing technologies during use, ensuring it maintains normal operation within the pipe and effectively preventing obstruction of subsequent operations due to device deformation, thereby improving the reliability and continuity of the dredging work.

[0036] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
