Description

Technical Field

[0001] The present invention relates to the technical field of sewer systems, and particularly to an electric pipeline dredging machine using centrifugal sewage discharge technology. Background Art

[0002] In the fields of municipal engineering, industrial drainage, and household pipeline maintenance, electric pipeline dredging machines, as key equipment for dealing with pipeline blockages and ensuring unobstructed sewage discharge, have complex application scenarios and diverse working conditions. Especially for electric pipeline dredging machines using centrifugal sewage discharge technology, they need to move and operate frequently in environments such as narrow pipeline spaces, damp basements, and outdoor operation sites.

[0003] For the current electric pipeline dredging machines on the market, there are many deficiencies in their handling structures. Some equipment shells do not have a special handrail structure. When operators handle the equipment, they can only directly grasp the corners of the shell or other non-designed stress-bearing parts. This not only makes the handling process extremely inconvenient but also may cause the equipment to tip over due to uneven stress, resulting in damage to precision components such as internal centrifugal separation devices and motors. At the same time, some equipment only installs rollers at the bottom and attempts to move by rolling. However, in complex working environments, such as construction sites full of obstacles and uneven ground, relying solely on rollers for movement is extremely inconvenient, and the equipment is easily blocked or overturned due to road conditions, thereby reducing the practicality of the equipment. Summary of the Invention

[0037] Please refer to Figure 1-8 , the present invention provides a technical solution: an electric pipeline dredger using centrifugal sewage discharge technology, including the main body 1 of the electric pipeline dredger, a pull rod 4, a cover plate 5, a control panel 6 and a solid dredging spring connector 7;

[0038] Handrail assemblies are provided on both sides of the main body 1 of the electric pipeline dredger;

[0039] The armrest assembly includes a connecting seat 2, a mounting seat 3 and an armrest 8. The mounting seat 3 is fixedly connected to one side of the upper end of the main body 1 of the electric pipeline dredging machine. The armrest 8 is in a "U" shape. An installation block groove 18 is formed in the outer wall of one end of the mounting seat 3 away from the main body 1 of the electric pipeline dredging machine. A mounting block 16 is fixedly connected to the outer wall of one side of the connecting seat 2. The outer wall of the mounting block 16 is slidably connected to the inside of the installation block groove 18. Second limiting block grooves 19 are formed in the inner walls on both sides of the installation block groove 18. Limiting blocks 11 are slidably connected to the inside of the two second limiting block grooves 19. First limiting block grooves 17 are formed in the outer walls on both sides of the mounting block 16. One end of each of the two limiting blocks 11 close to the first limiting block groove 17 slidably extends into the inside of the installation block groove 18 and is respectively slidably connected to the inside of the corresponding first limiting block groove 17. Convex blocks 9 are fixedly connected to the outer walls on both sides of the mounting seat 3. A rotating threaded rod sleeve 13 is rotatably connected to the inner outer wall of the two convex blocks 9. The two sides of the armrest 8 are rotatably connected to the inner walls on both sides of one end of the connecting seat 2 away from the mounting seat 3. The inside of the two convex blocks 9 communicates with the inside of the corresponding second limiting block groove 19 respectively. Rotating threaded rods 12 are arranged inside the two second limiting block grooves 19. One end of each of the two rotating threaded rod sleeves 13 close to the limiting block 11 rotatably extends into the inside of the second limiting block groove 19. One end of the rotating threaded rod 12 close to the limiting block 11 is rotatably connected to the outer wall of the limiting block 11. The end of the rotating threaded rod 12 away from the limiting block 11 is threadedly connected to the inside of the rotating threaded rod sleeve 13. The two armrest assemblies are arranged on both sides of the upper end of the main body 1 of the electric pipeline dredging machine.

[0040] Among them, a pull rod 4 is installed at the rear end of the main body 1 of the electric pipeline dredging machine. A partition plate 10 is fixedly connected to the inside of the placing groove at the upper end of the main body 1 of the electric pipeline dredging machine. The partition plate 10 is arranged in a cross shape. A cover plate 5 is installed inside the placing groove at the upper end of the main body 1 of the electric pipeline dredging machine. A control panel 6 is installed on the front outer wall of the main body 1 of the electric pipeline dredging machine. The control panel 6 is electrically connected to the main body 1 of the electric pipeline dredging machine. A solid dredging spring connector 7 is installed at the front end of the main body 1 of the electric pipeline dredging machine. The solid dredging spring connector 7 is electrically connected to the control panel 6. A water outlet pipe 15 is installed at the rear end of the main body 1 of the electric pipeline dredging machine. The water outlet pipe 15 is electrically connected to the control panel 6. Two crawler-type stair-climbing assemblies 14 are installed at the rear end of the main body 1 of the electric pipeline dredging machine. The two crawler-type stair-climbing assemblies 14 are electrically connected to the driving mechanism inside the main body 1 of the electric pipeline dredging machine.

[0041] Furthermore, when using this device, it is started by connecting to an external power supply. Align the mounting block 16 on the connecting seat 2 with the mounting block slot 18 on the mounting seat 3 and insert it, so that the mounting block 16 can slide within the mounting block slot 18. Then rotate the rotating threaded rod sleeve 13. Since the rotating threaded rod sleeve 13 is threadedly connected to the rotating threaded rod 12, the rotation of the rotating threaded rod sleeve 13 will drive the rotating threaded rod 12 to move linearly, thereby pushing the limiting block 11 to slide from the second limiting block slot 19 into the mounting block slot 18 until the limiting block 11 is inserted into the first limiting block slots 17 on both sides of the mounting block 16, fixing the connecting seat 2 and the mounting seat 3 together, completing the installation of the armrest 8. At the same time, the armrest 8 is rotatably connected to the connecting seat 2, and the operator can adjust the angle of the armrest 8 according to actual operation requirements to obtain a more comfortable operating posture. The operator moves the main body 1 of the electric pipe dredger to the position of the pipe to be dredged through the pull rod 4, connects the solid dredging spring to the solid dredging spring connector 7, and starts the main body 1 of the electric pipe dredger through the control panel 6. The centrifugal sewage discharge device inside the equipment starts to work. At the same time, the solid dredging spring connector 7 drives the solid dredging spring to rotate and extend into the pipe interior. During the rotation of the solid dredging spring, it stirs and dredges the blockage in the pipe, breaking or pushing the blockage. During the dredging process, the sewage will be discharged from the water outlet pipe 15 through the centrifugal force generated by the centrifugal sewage discharge device. When the pipe dredging is completed, turn off the main body 1 of the electric pipe dredger through the control panel 6 to stop the operation of the equipment. When it is necessary to disassemble the connecting seat 2 and the armrest 8, reverse the rotation of the threaded rod 12 to move the limiting block 11 to slide within the second limiting block slot 19. When the limiting block 11 completely slides out of the first limiting block slots 17 on the outer walls of both sides of the mounting block 16, the mounting block 16 is no longer limited. At this time, since the outer wall of the mounting block 16 is slidably connected to the interior of the mounting block slot 18 on the mounting seat 3, the mounting block 16 on the connecting seat 2 can be slid out of the mounting block slot 18, thus separating the connecting seat 2 from the mounting seat 3.

[0042] Through the armrest assembly, the operator can adjust the angle of the armrest 8 according to actual operation requirements to obtain a more comfortable operating posture. When moving the equipment to the operation site or fine-tuning the position of the equipment during the dredging process, the armrest 8 provides a stable grasping point for the operator. Compared with directly holding the main body of the equipment, applying force through the armrest is more ergonomic, enabling the operator to more easily and precisely control the moving direction and force of the equipment, avoiding operation difficulties or accidental collisions caused by the heavy equipment, and thus improving the practicality and flexibility of the equipment.

[0043] Structural Description: The main body 1 of the electric pipe dredger: As the core part of the entire device, it bears the installation and operation of each component. There is a pull rod 4 installed at the rear end for easy movement. There is a placement groove at the upper end. Inside the placement groove, a cross-shaped partition plate 10 is fixedly connected and a cover plate 5 is placed. A control panel 6 for controlling the device is installed on the outer wall of the front end. A solid dredging spring connector 7 is also installed at the front end. An outlet pipe 15 is provided at the rear end. Inside the main body 1 of the electric pipe dredger, a centrifugal disc and an oil replenishing pot are installed. At the same time, there is a protection device on the main body 1 of the electric pipe dredger. During the dredging process, when the dredging drill bit encounters resistance, this resistance will act on the motor through the dredging wire rope. Once the motor torque generated by this reaction force exceeds the warning value of 15 N / M, the warning light strip will automatically light up. Then, the one-key start and one-key recovery of the wire rope and power cord functions on the main body 1 of the electric pipe dredger greatly improve the operation convenience and usage efficiency of the device. The one-key start function is realized through an independent start button set on the device operation panel. When the operator is ready to carry out pipe dredging operations, just press the one-key start button, and the intelligent control system inside the device will start immediately. It quickly completes the self-inspection of core components such as the motor and transmission mechanism. After confirming no abnormalities, it precisely controls the motor to drive the dredging drill bit to rotate at a preset speed, and at the same time releases the wire rope in an orderly manner, driving the dredging drill bit to smoothly enter the pipe to carry out dredging work. The entire start-up process does not require cumbersome step-by-step operations and parameter settings, greatly shortening the device start-up time and improving work efficiency. At the same time, the one-key recovery function relies on the coordinated operation of a delicate winding mechanism and an intelligent control module inside the device. This winding mechanism adopts a dual-axis linkage design, corresponding to the recovery of the wire rope and the power cord respectively, and is equipped with a high-precision torque sensor and a speed adjustment device. When the pipe dredging operation is completed, the operator presses the one-key recovery button. The torque sensor real-time monitors the resistance change during the recovery of the wire rope and the power cord. The intelligent control module dynamically adjusts the motor speed and winding force according to the monitored data to ensure that the wire rope and the power cord are recovered into the storage bin inside the device main body at a uniform and stable state.
