Embodiment 1

[0024] This embodiment provides an automatic dredging device applied to a pipeline detection robot, such as Figure 1-2 As shown, among them,

[0025] The detection module 100 detects whether there is an obstacle ahead, and judges the type of obstacle; the dredging module 200 includes a drive motor 201, the drive motor 201 is connected with a telescopic unit 202, and the end of the telescopic unit 202 is set as a tapered drill bit 203, and the telescopic unit 202 is A rotating brush head 204 is also provided. When the robot is walking, when the detection module 100 detects an obstacle ahead, it will transmit a signal to make the dredging module 200 work to dredge the obstacle ahead.

[0026] Further, the telescopic unit 202 includes a threaded rod 202a, a sleeve 202b is provided on the outside of the threaded rod 202a, an internal thread is provided on the inner wall of the sleeve 202b to engage with the threaded rod 202a, and a fixed sleeve 202c is provided on the outside of...

Embodiment 2

[0031] This embodiment is different from the previous embodiment in that, as Figure 1-3 As shown, among them,

[0032] The vehicle frame 301 is provided with a walking unit 302 below the vehicle frame, an underwater power unit 303 is provided at the rear of the vehicle frame, and a power conversion device 400 is provided below the vehicle frame; the vehicle frame 301 is the main body of the whole robot, and the remaining functional modules are installed on the vehicle On the shelf, the unit module used to drive the robot to run includes a walking unit 302, an underwater power unit 303, and a power conversion device 400. The walking unit 302 can control the robot to move forward on land with no or a small amount of water accumulation, and the underwater power unit 303 can control the robot to move forward. The power unit 303 controls the robot to run forward in the deep water in the sewer, and the power conversion device 400 is used to automatically control the conversion of t...

Embodiment 3

[0038] This embodiment is different from the previous embodiment in that, as Figure 1-3 As shown, the vehicle frame 301 is also provided with a laser positioning module, an image acquisition module, a supplementary light module and a power supply module, and also includes a remote control system.

[0039] The laser positioning system includes a control chip, a transmitter, a receiver and a modem connected to the control chip. The laser signal is sent from the transmitter to the positioning board, and then reflected back to the receiver by the reflector on the positioning board, processed by the control chip, and After modulation and demodulation, the positioning information is transmitted to the remote control system to realize real-time monitoring.

[0040] The image acquisition module includes a 360-degree panoramic camera, which is arranged on the top of the vehicle frame 301, has a good field of vision and is convenient for framing.

[0041] The supplementary light modul...

Abstract

The invention provides an automatic dredging device applied to a pipeline detection robot. The automatic dredging device comprises a detection module and a dredging module, wherein the detection module detects whether an obstacle exists in front or not, and judges the type of the obstacle. The dredging module comprises a driving motor, the driving motor is connected with a telescopic unit, a conical drill bit is arranged at the end of the telescopic unit, and a rotary brush head is further arranged in the circumferential direction of the telescopic unit. When the robot encounters an obstacle in a pipeline, the dredging module can be adopted to clean and dredge the obstacle in front, continuous operation and detection of a vehicle body are facilitated, and when the robot encounters blockage of sundries such as stones which are difficult to dredge, an anti-overload unit can guarantee operation safety of a driving motor; and meanwhile, an operator is provided with a signal to confirm the accurate position needing manual dredging, and the location of the problem pipeline is found.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to an automatic dredging device applied to a pipeline detection robot. Background technique [0002] With the development and progress of cities, concrete underground pipelines have become an indispensable part of urban infrastructure construction. Concrete underground pipes can be seen everywhere in the city, and people use pipes to send water, air, sewage and so on. Such a dense distribution of pipelines brings about the problem of pipeline maintenance. However, because the environment where pipelines are located is often limited by manpower or out of reach, maintenance is very difficult. Usually, regular or regular maintenance is used for important pipelines that are not allowed to leak. The method of scrapping ahead of time has caused huge loss of manpower and material resources. At present, the quality inspection of underground transmission pipelines often adopts the excavatio...
