[0004] In response to the shortcomings of the existing technology, the present application provides an underground pipeline inspection robot that can be applied to pipelines of different diameters, is convenient for cleaning dirt at damaged pipes, can accurately inspect the condition of damaged pipes, and improves the efficiency of pipeline inspection. It solves the problem that current pipeline inspection robots cannot be applied to pipes of different diameters when in use, are inconvenient for cleaning dirt at damaged pipes, and cannot accurately inspect the condition of damaged pipes, which affects the effect of pipeline inspection.

[0005] In order to achieve the above-mentioned purpose of being applicable to pipelines of different diameters, conveniently cleaning dirt at damaged parts of pipelines, accurately inspecting the conditions of damaged parts of pipelines, and improving the efficiency of pipeline maintenance, the present application provides the following technical solutions: an underground pipeline maintenance robot, comprising a chassis, a first electric push rod being provided on one side of the chassis, a connecting plate being provided on the other end of the first electric push rod, a swing arm being hingedly connected to one side of one end of the push rod through a hinge frame, a telescopic outer tube being provided on the other end of the push rod, a telescopic inner rod being inserted into the inner wall of one end of the telescopic outer tube, a push plate being provided on one end of the telescopic inner rod, and a driving wheel being provided on one side of the push plate which is rotated by a rotating frame;

[0006] A motor is provided on the side of the chassis away from the first electric push rod, a second electric push rod is provided at one end of the motor through a connecting block, a protective box is provided at one end of the second electric push rod, a camera is provided inside the protective box, and a flushing nozzle is provided on one side of the protective box through a fixing plate.

[0007] Through the above scheme, the first electric push rod drives the connecting plate to move, so that the connecting plate drives the swing arm to swing, so that the swing arm drives the push rod to move, and the distance between the drive wheel and the chassis is adjusted. The dirt on the pipe can be cleaned by the flushing nozzle, which makes it suitable for pipes of different diameters, facilitates the cleaning of dirt at damaged parts of the pipe, can accurately inspect the condition of the damaged part of the pipe, and improves the efficiency of pipeline maintenance.

[0008] Furthermore, the driving wheels are arranged in three groups, each group has two driving wheels, and the two driving wheels in each group are respectively rotatably arranged at two ends of one side of the push plate through a rotating frame.

[0009] Through the above solution, the three sets of driving wheels can support each other so that the chassis can be located at the center of the circle inside the pipe. The two driving wheels in each set can fix the angle of the robot inside the pipe, preventing the robot from tipping over inside the pipe and improving the stability of the robot when the driving wheels drive it to move.

[0010] Furthermore, there are three swing rods, one end of each of the three swing rods is hinged to one side of one end of each of the three push rods through three hinge frames, and the other ends of each of the three swing rods are hinged to three sides of the connecting plate through three hinge frames.

[0011] Through the above solution, the movement of the connecting plate can simultaneously drive the three swing arms to swing, thereby simultaneously adjusting the positions of the three push rods, thereby simultaneously adjusting the distances between the three sets of driving wheels and the chassis.

[0012] Furthermore, the outer surface of the middle portion of the push rod is slidably arranged in the inner wall of the middle portion of the limit frame, one end of the limit frame is arranged on one side of the support plate, and one end of the support plate is arranged on one side of the chassis.

[0013] According to the above solution, the trajectory of the push rod during movement can be fixed by setting the limit frame, thereby improving the stability of the push rod during movement.

[0015] Through the above scheme, a thrust can be applied to the telescopic inner rod through the setting of the spring, pushing the driving wheel to stably contact the inner wall of the pipe. When the driving wheel moves in the pipe and passes through obstacles such as dirt, the telescopic inner rod will be inserted into the telescopic outer tube to compress the spring, so that the driving wheel can smoothly cross the obstacle. After crossing, the spring will release the thrust so that the telescopic inner rod pushes the driving wheel to reset through the push plate, so that the driving wheel is close to the inner wall of the pipe again.

[0016] Furthermore, a lighting lamp is provided inside the protective box.

[0017] Through the above solution, the camera shooting position can be illuminated by setting the lighting lamp, improving the camera shooting conditions, so that the camera can shoot and inspect the inner wall of the pipeline more clearly.

[0018] Furthermore, a protective cover is slidably provided on one side of the protective box via an electric slide rail, and the protective cover is transparent.

[0019] Through the above solution, the camera and the lighting can be protected by setting the protective cover to prevent dirt from splashing onto the camera and the lighting when flushing the inner wall of the pipe, affecting the shooting and lighting. The transparent setting of the protective cover can protect the camera while the camera can roughly capture the flushing situation of the flushing nozzle on the pipe through the protective cover. After the protection is completed, the protective cover can be moved away from the side of the camera by the electric slide rail to prevent it from affecting the camera's shooting.

[0020] Furthermore, edge banding strips are provided at both ends of one side of the protective cover plate.

[0021] Through the above solution, the setting of the edge banding can fill the gap between the two ends of one side of the protective cover and the two ends of one side of the protective box, preventing sewage from splashing into the inside of the protective box and contaminating the camera and lighting.

[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

It is suitable for pipelines with different diameters, facilitates the cleaning of dirt at damaged parts of the pipeline, can accurately inspect the condition of the damaged part of the pipeline, and improves the efficiency of pipeline inspection.
