Description

Technical Field

[0001] The invention relates to the technical field of municipal pipeline cleaning devices, and in particular to a pipeline dredging robot. Background Art

[0002] Climate change has increased the probability of extreme weather. In the process of urbanization, the reduction of muddy land and the unreasonable design of drainage systems have made it impossible for the surface to effectively absorb rainwater, leading to drainage problems within cities and exacerbating the risk of floods within cities. Nowadays, the main reason for the frequent floods is still the problems related to drainage pipes. For example, the drainage systems in many areas have been used for a long time. Under the impact of long-term water flow, the material strength and quality of the pipes have declined, and even rupture and leakage have occurred. In addition, some pipes have design defects, resulting in unsmooth water flow and increasing the risk of blockage. Due to the lack of pipeline maintenance, a lot of urban garbage and industrial waste are washed into the sewer pipes when it rains, and then mixed with silt, which is extremely easy to cause blockage of the sewer pipes. This is also the main cause of floods. Floods will not only destroy public facilities, damage buildings and traffic roads, and cause huge property losses, but also affect people's daily lives and cause travel difficulties. The most serious is that floods may cause casualties. Therefore, in order to prevent floods, it is necessary to strengthen the maintenance of drainage pipes and the dredging of pipes, and clean the pipes regularly.

[0003] Traditional dredging methods, such as winch dredging, manual dredging, high-pressure water jet dredging and trench cleaning, have their own uses, but all have significant limitations. Dredging by winch requires closing roads, which not only affects public travel, but also poses a challenge to manual cable threading in the complex pipeline environment, threatening the health and safety of operators. Manual dredging occupies a large area, is prone to environmental pollution, and is inefficient, especially in the face of toxic gases that may exist in urban drainage pipes, which poses a serious threat to the life safety of operators. Although high-pressure water jet dredging is effective, it is easy to cause damage to the pipeline and consumes a lot of water resources. Trench cleaning machines are difficult to adapt to variable pipe diameters. In view of these challenges, it is necessary to develop a pipeline robot that is small in size, light in weight, flexible in and out of the pipeline, simple in driving mode, and can easily adapt to different pipeline environments.

DETAILED DESCRIPTION

[0020] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0021] Please refer to Figure 1 A pipeline dredging robot of the present invention includes a hydraulic cycloid motor, a sleeve housing 1, a connecting shaft 5 and a cutting disc 6.

[0022] The sleeve body 1 is a round sleeve body, and the hydraulic cycloidal motor is a cylindrical structure. The lower end of the hydraulic cycloidal motor is provided with a water inlet, and the upper end is provided with a water outlet. The hydraulic cycloidal motor is a hydraulic transmission element, and its main function is to convert the hydraulic energy of the high-pressure water flow into mechanical energy. An output shaft is provided on the top of the hydraulic cycloidal motor. The high-pressure water flow enters from its water inlet and flows out from the water outlet. The water pressure at its water inlet is greater than the water pressure at its water outlet. The internal components of the hydraulic cycloidal motor convert the pressure difference into the rotational kinetic energy of the output shaft. In this embodiment, the hydraulic cycloidal motor is a GPH80 type hydraulic cycloidal motor. The round sleeve body is sleeved outside the hydraulic cycloidal motor, and a fixing screw 7 is also provided on the sleeve body 1. The fixing screw 7 is perpendicular to the axis of the sleeve body 1. The end of the fixing screw 7 passes through the sleeve body 1 and presses the outer wall of the hydraulic cycloidal motor, thereby locking and fixing the hydraulic cycloidal motor.

[0025] The water inlet pipe is used to introduce high-pressure water into the casing body 1.

The high-pressure water flows into the hydraulic cycloid motor from the water inlet of the hydraulic cycloid motor, driving the cutting disc 6 connected to the hydraulic cycloid motor to rotate, so that the cutting disc 6 can cut and crush the steel bars, cement blocks, branches and other solid impurities attached to the inner wall of the (underground drainage pipe) pipe, and the water sprayed from the water outlet of the hydraulic cycloid motor can wash the inner wall of the underground drainage pipe, thereby completing the automatic dredging process.

[0027] Preferably, when the water spray holes on the water outlet end cover 2 of the pipeline dredging robot spray water, the rotation direction of the sprayed water is opposite to the rotation direction of the cutting disk 6, so as to ensure that the casing body maintains dynamic balance in the direction of its circular axis (that is, the torque generated by the reaction force of the water spray holes on the water outlet end cover 2 on the pipeline dredging robot and the torque generated by the rotation of the cutting disk 6 on the pipeline dredging robot offset each other), preventing the casing body from rotating during the cleaning process along the pipeline and causing the water inlet pipe to twist, thereby ensuring normal water supply through the water inlet pipe, thereby making the dredging process of the pipeline dredging robot in the pipeline smooth.
