Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical engineering, in particular to a multifunctional urban underground drainage pipe desilting and maintenance robot. Background Art

[0002] After long-term use, drainage pipes will cause silt deposition, which needs to be cleaned in time. If they are not cleaned in time, the sewage pipes will be blocked, causing sewage backflow and even urban flooding disasters, which will greatly affect the living environment of residents and cause immeasurable losses.

[0003] The few existing pipeline desilting robots on the market are mostly suitable for small drainage pipes. Small robots have low desilting efficiency after entering the pipes, or even become completely mired in the mud and unable to move. Larger desilting robots cannot enter the drainage pipes through surface inspection wells. Digging up the inspection wells would waste a lot of manpower and resources, seriously affecting residents' daily lives. Furthermore, since most current desilting robots use fixed wheels or tracked travel mechanisms and desilting agitation devices, they are poorly adaptable to circular pipes and are difficult to adapt to desilting operations in pipes of different diameters. As the total length of drainage pipes in my country continues to grow, the shortage of desilting workers and low desilting efficiency have created an imbalance between supply and demand, coupled with the ever-expanding market. Therefore, developing a pipeline desilting robot that can be used in medium and large pipelines and can enter the pipelines through surface inspection wells is of great significance in terms of protecting the lives of practitioners, improving pipeline desilting efficiency, and avoiding pipeline congestion.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Embodiment 1, by Figures 1-6 It is given that the utility model includes an adaptive crawler walking mechanism 1, an electrical control system 2, a lifting platform 3, a visual detection and high-pressure dilution device 4 and a sludge stirring device 5.

[0028] When the robot enters the pipeline, the adaptive crawler walking mechanism 1 adjusts the swing mechanism 1.6 and the axial fixing device 1.4 so that the crawler 1.1 can fit tightly against the inner wall of the pipeline, ensuring the stable movement of the robot in the pipeline. The DC drive motor 1.3 drives the crawler 1.1 to rotate, generating forward power, and the waterproof motor box 1.8 protects the drive motor 1.3 from the influence of the humid environment.

[0029] Specifically, the electrical control system 2 includes an operating platform 2.1, a packaging box 2.2, and a sleeve 2.3. The packaging box 2.2 is installed on the upper end of the operating platform 2.1, and the electrical control system hardware is encapsulated inside the packaging box 2.2. The sleeve 2.3 is connected to the lower end of the operating platform 2.1, and the mobile platform 1.2 is connected to the sleeve 2.3.

[0030] The electrical control system 2 is responsible for the power supply, signal transmission and program control of the entire robot. The operating platform 2.1 provides the installation platform for the entire device. The packaging box 2.2 encapsulates the electrical control system hardware, including the controller, power module, communication module, etc., to facilitate human-computer interaction and facilitate the operator to remotely monitor and operate the robot.

[0031] Specifically, the lifting platform 3 includes a motor packaging box 3.1, an active connecting rod 3.2, a hydraulic telescopic rod 3.3, a driven connecting rod 3.4, a pendulum fixing device 3.5 and a fixed panel 3.6.

A dual-axis motor is installed inside the motor packaging box 3.1.

The fixed panel 3.6 is installed at the front end of the pendulum fixing device 3.5.

[0032] The lifting platform 3 uses a dual-axis motor in a motor packaging box 3.1 to drive the coordinated movement of the active connecting rod 3.2 and the driven connecting rod 3.4, achieving the up and down movement of the visual inspection and high-pressure dilution device 4 and the sludge stirring device 5. The active connecting rod 3.2 and the driven connecting rod 3.4 form a stable parallelogram mechanism, ensuring that the visual inspection and high-pressure dilution device 4 can be precisely adjusted in height within a range of 0-30 cm. The hydraulic telescopic rod 3.3 is used to assist in adjusting the inclination angle of the device to meet the requirements of pipeline dredging at different depths.

[0033] Specifically, the visual inspection and high-pressure dilution device 4 includes a visible light camera 4.1, a fixing plate 4.2, a connecting hole 4.3, a light source 4.4, and a high-pressure water jet 4.5. The visible light camera 4.1 is mounted in the lower center of the fixing plate 4.2, and the light source 4.4 and the high-pressure water jet 4.5 are both mounted on the upper part of the fixing plate 4.2, with the light source 4.4 being higher than the installation position of the high-pressure water jet 4.5.

[0034] Visible light camera 4.1 captures images of the interior of the pipeline in real time and transmits them to electrical control system 2 for processing and analysis. Light source 4.4 provides illumination to ensure that the camera can clearly capture the interior of the pipeline. High-pressure jet water gun 4.5 uses high-pressure water flow to initially dilute the silt in the pipeline, facilitating subsequent stirring and cleaning.

[0035] Specifically, the sludge stirring device 5 includes two dredging discs 5.1, a support device 5.2, cutting teeth 5.3 and a hub motor 5.4.

The hub motor 5.4 is installed on the inner side of the support device 5.2.

[0036] The hub motor 5.4 drives the silt removal disc 5.1 to rotate. The cutting teeth 5.3 on the outside of the silt removal disc 5.1 cut and stir the silt attached to the inner wall of the pipe, which can effectively chop up larger particles in the pipe and stir the silt. During the stirring process, the silt is gradually broken up and loosened, which is convenient for subsequent high-pressure water flushing and collection.

[0037] Working principle: The operator starts the robot through the electrical control system 2. The adaptive crawler walking mechanism 1 adjusts the crawler 1.1 to allow the robot to enter the pipeline stably. The lifting platform 3 adjusts the height and inclination angle of the visual inspection and high-pressure dilution device 4 and the sludge stirring device 5 according to the pipeline depth. The visual inspection and high-pressure dilution device 4 starts working. The visible light camera 4.1 captures the image of the interior of the pipeline. The light source 4.4 provides lighting. The high-pressure jet water gun 4.5 performs preliminary dilution of the sludge. The sludge stirring device 5 is started. The silt cleaning disc 5.1 and cutting teeth 5.3 cut and stir the sludge. The stirred sludge is washed to the bottom of the pipeline by the high-pressure water flow for subsequent collection and processing.

[0038] In summary, the multifunctional urban underground drainage pipe desilting and maintenance robot of the present invention realizes efficient and safe desilting and maintenance of the interior of the drainage pipe through an integrated design.
