Description

Technical Field

[0001] This invention relates to the field of sewer dredging technology, specifically to a pipe network structure, dredging device, and dredging method that facilitates dredging. Background Technology

[0002] Pipeline dredging refers to clearing silt and other waste from pipelines to ensure their long-term smooth flow and prevent urban flooding. Existing pipe networks often accumulate large amounts of sludge after sewage transport. If not cleaned regularly, this sludge buildup will impede normal drainage. Furthermore, the lack of regular dredging can cause sewage overflows, polluting the environment and causing inconvenience to residents.

[0003] The existing pipeline network structure is relatively simple, often consisting of two pipes directly connected and fixed, providing only drainage. Dredging requires manual labor and auxiliary machinery, resulting in low dredging efficiency, slow speed, and incomplete cleaning. Furthermore, the lack of real-time monitoring of the pipe inner wall during sludge removal makes it impossible to determine whether the inner wall of the pipe is damaged or cracked, which is inconvenient for subsequent pipeline maintenance.

[0004] Currently, there are pipe cleaning robots on the market that can remove silt from pipes. However, when too much silt accumulates, the robot's movement is easily obstructed and the wheels slip, making it impossible to perform efficient silt removal operations. At the same time, existing silt removal equipment cannot perform silt removal operations on pipes of different sizes, especially for pipes crossing rivers, inverted siphon pipes, drainage pipes with large burial depths, and pipes with high water levels and high siltation, which are not very flexible.

[0005] Therefore, how to improve the efficiency of pipeline dredging has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0104] S60: The inner wall of the drainage pipe 10 is inspected using the camera 119 and the lighting strip 118 on the vehicle body 100.

[0105] In a specific embodiment, a dredging method is provided, which uses the aforementioned dredging device and includes the following steps:

[0106] S10: Pipeline laying.

[0107] Specifically, the sewage pipe 21 is first buried in the sand and gravel layer 60, and then a tee pipe 22 is installed at equal intervals to form a sewage pipe 20 through the sewage pipe 21 and the tee pipe 22.

[0108] Then, a support frame is erected, and the drainage pipe 10 is assembled above the sewage pipe 20. That is, the pipe plug 12 at one end of the drainage pipe 11 is inserted into the pipe slot 13 of another drainage pipe 11, and the connection is sealed and fixed by connecting flange 14 and sealing gasket. During assembly, the connecting pipe 30 at the bottom of part of the drainage pipe 11 needs to be connected to the tee pipe 22. Then, a sewage station is built or a suction pump 50 is installed at one end of the sewage pipe 20.

[0109] S20: Select 400 shovel bucket.

[0110] Specifically, according to the size and cross-sectional shape of the drainage pipe 10, a corresponding shovel hopper 400 is selected, and the mounting plate 418 of the shovel hopper 400 is detachably and fixedly connected to the connecting plate 417 at one end of the square tube 419 by bolts and nuts. Then, the entire dredging device is placed into the drainage pipe 10.

[0111] S30: Adjust the vehicle body by 100.

[0112] The remote control 500 controls the oil pump 117 to be powered on, thereby pumping the hydraulic oil in the oil tank 116 into the lifting cylinder 113. The extension of the lifting cylinder 113 raises the upper frame 111 to an appropriate height. At the same time, the remote control 500 controls the second drive motor 340 of the telescopic arm 300 to be powered on, causing the telescopic arm 300 to extend and increase the horizontal distance between the drive wheel 200 and the vehicle body 100, so that the anti-slip tires 240 at the four corners of the upper frame 111 and the lower frame 112 come into contact with the inner wall of the drainage pipe 10.

[0113] S40: The third drive motor 210 on the drive wheel 200 is powered on by the remote control 500, which drives the wheel hub 230 and the anti-skid tire 240 to rotate, so as to drive the sludge removal device to move forward in the drainage pipe 10. The shovel 412 on the shovel hopper 400 is used to shovel off the sludge on the inner wall of the drainage pipe 10. The sludge accumulates in the shovel hopper 400. As the sludge removal device moves forward, more and more sludge accumulates in the shovel hopper 400.

[0114] S50: The first drive motor 415 connected to the auger 414 is powered on by the remote control 500, thereby driving the auger 414 to rotate through gear transmission. The rotation of the spiral blades on the auger 414 transports the sludge accumulated in the shovel 400 to the feed hopper 120. The feed hopper 120 then transports the sludge to the sludge conveying channel 115, where it is continuously compressed and conveyed to the discharge hose 600, from where it is discharged. Alternatively...

[0115] By opening the solenoid valve 40 at the corresponding position at the bottom of the drainage pipe 10 through the control switch on the sewage station, the drainage pipe 10 is connected to the sewage pipe 20, and the accumulated sludge enters the sewage pipe 20 through the connecting pipe 30. The suction pump 50 at one end of the sewage pipe 20 is turned on, creating negative pressure in the sewage pipe 20, thereby drawing the sludge out of the sewage pipe 20 and improving the sludge cleaning efficiency.

[0116] S60: When cleaning sludge, the inner wall of the drainage pipe 10 can be inspected through the camera 119 and the lighting strip 118 on the upper frame 111 and the lower frame 112. The video is transmitted back to the display screen of the remote control 500, which makes it easy to mark the damaged parts of the drainage pipe 10 and facilitates later fixed-point maintenance.

[0117] Compared with the prior art, this application has at least the following beneficial technical effects:

[0118] This application provides a sewage discharge pipe installed parallel to the drainage pipe below it, and achieves point-to-point connection between the drainage pipe and the sewage discharge pipe through a connecting pipe and a solenoid valve. This allows for targeted suction and discharge of sludge accumulated in the drainage pipe, thereby improving the sludge cleaning efficiency of the drainage pipe.

[0119] The cross-section of the drainage pipe in this application can be square or circular. Multiple connecting pipes are arranged in parallel between the drainage pipe and the sewage pipe, and a solenoid valve is installed at the top of the connecting pipe. By controlling the opening or closing of the solenoid valve and with the assistance of the sludge removal device, the sludge in the drainage pipe can be quickly and centrally cleaned.

[0120] The dredging device of this application has a telescopic arm connected between the vehicle body and the drive wheels on both sides. The horizontal distance between the vehicle body and the drive wheels can be adjusted by extending and retracting the telescopic arm to adapt to sewage pipes of different diameters and shapes. It is particularly suitable for cross-river pipes, inverted siphon pipes, drainage pipes with large burial depths, and high-water-level, high-siltation pipes. It not only has the advantages of high flexibility and wide applicability, but also ensures that the dredging device has sufficient power for dredging, avoiding the phenomenon of slippage and free rotation of the drive wheels, which is conducive to the normal operation of the dredging device.

[0121] This application features a detachable shovel bucket at the front of the vehicle body, which can be replaced with different sized shovel buckets to clean sludge from drainage pipes of different sizes. The auger connected between the conical bucket and the vehicle body can quickly remove the sludge accumulated on the bucket and can also be used in conjunction with the sewage pipe below the drainage pipe for auxiliary sludge removal, which helps to improve sludge removal efficiency.

[0122] The dredging method described in this application utilizes a dredging device in conjunction with a pipeline structure that facilitates dredging. This method not only achieves high dredging efficiency and speed but also improves the operational performance of the dredging device.

[0123] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
