[0030] Example 1

[0031] Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, and provides a patrol robot for checking broken strands of a power transmission line, which can achieve contact and fit between a sensing device and a power transmission line, and greatly improve the accuracy of broken strand detection of the power transmission line, and comprises a mounting component 100, comprising a main frame 101, a detection slot 102 arranged on one side of the main frame 101, a fixed end 103 arranged in the detection slot, a movable end 104 arranged in the detection slot 102, a sensor 105 arranged in the detection slot 102, and support frames 106 arranged on both sides of the main frame 101;

[0032] The moving part 200 includes a moving assembly 201 arranged on the support frame 106, the moving assembly 201 includes a rotating groove 201a arranged on the support frame 106, a rotating tube 201b is rotatably connected in the rotating groove 201a, a movable frame 201c is slidably connected in the rotating tube 201b, one end of the movable frame 201c is rotatably connected to a driving wheel 201d, one side of the movable frame 201c is fixedly connected to a direct drive motor 201e, the output shaft of the direct drive motor 201e is fixedly connected to the driving wheel 201d, and a cleaning assembly 202 is arranged on the support frame 106, the cleaning assembly 202 includes a mounting frame 202a fixedly connected to one side of the support frame 106, and one side of the mounting frame 202a is fixedly connected to a cleaning The cleaning frame 202b has a circulation port 202c on one side thereof, a movable assembly 203 arranged on the main frame 101, a positioning assembly 204 arranged on the main frame 101, the movable assembly 203 includes a connecting groove 203a opened on one side of the supporting frame 106, a sliding frame 203b is slidably connected in the detection groove 102, a moving frame 203c is fixedly connected on one side of the sliding frame 203b, a guide rod 203d is fixedly connected on one side of the moving frame 203c, and the guide rod 203d extends into the main frame 101, a mounting bolt 203e is arranged on one side of the movable frame 201c, a top plate 203f is arranged on one side of the mounting bolt 203e, and a supporting groove 203g is opened on one side of the top plate 203f.

[0033] Specifically, the contact wheel is a double-layer with multiple evenly spaced distributions. Through the double-layer distribution of the upper and lower structures, it can provide bidirectional drive for the device when it moves in the up and down directions, while ensuring its stable support when detecting the broken position of the transmission line. At the same time, the torsion spring on the rotating tube 201b can maintain the friction between the contact wheel and the pipe wall, thereby ensuring that the device can be driven and supported in the up and down directions in the pipeline. Secondly, each driving wheel 201d is driven by a separate, synchronously controlled direct-drive motor 201e, which can provide sufficient driving power for the movement of the device.

[0034] Among them, the movable component 203 can achieve convenient disassembly of the movable end 104, quickly set the transmission line between the fixed end 103 and the movable end 104, and facilitate the fitting sensing effect of the transmission line during the detection process.

[0035] When in use, firstly, the sliding frame 203b, the moving frame 203c and the guide rod 203d are separated from the main frame 101, and at this time, the top plate 203f drives the rotating frame 204c installed movably on one side to move, and at this time, the T-shaped block 204b slides in the T-shaped groove 204a, which can provide a sliding limit for the movement of the rotating frame 204c, and ensure the stability of the movable end 104 during the movement. Then, the power transmission line enters the detection groove 102 through the connecting groove 203a, and the sliding frame 203b is matched with the detection groove 102, and the movable end 104 is installed in the detection groove 102. After adjusting the position of the movable end 104, the movable end 104 is fixed, and at this time, the power transmission line and the fixed end 103 can be realized. , the fitting detection effect of the movable end 104 is ensured to ensure its detection quality, thereby reducing the detection error. During the movement of the device, the direct drive motor 201e on one side of the driving wheel 201d provides power for the rotation of the driving wheel 201d. At this time, the rotating tube 201b and the movable frame 201c, under the traction of the torsion spring, make the driving wheel 201d contact with the inner wall of the pipeline, providing contact conditions for the movement of the device. During the movement of the device, the mounting frame 202a and the cleaning frame 202b are driven to contact and clean the pipeline where the transmission line is located, so as to avoid the problem of residual impurities in the pipeline causing corrosion or damage to the transmission line. At the same time, the impurities are discharged through the flow port 202c to avoid blockage.

[0036] In summary, by moving the device vertically and horizontally in the pipeline, the broken strand detection process of the power transmission line in the pipeline can be carried out, and the fit detection between the sensor 105 and the line can be realized to reduce the problem of detection error. At the same time, the impurities in the pipeline where the line is located can be cleaned to avoid corrosion or damage to the line.

Different from the previous embodiment, this embodiment provides a buffer component 206 of an inspection robot for inspection of broken strands of transmission lines, which solves the problem of convenient cleaning of impurities accumulated on the surface of the transmission line in the pipeline, avoids interference of impurities with the inspection of broken strands of the transmission line, and avoids corrosion of the transmission line caused by accumulated impurities, which includes.

[0041] During use, when the driving wheel 201d is bumpy or in contact with an extrusion state during its movement in the pipeline, the buffer rod 205a and the buffer spring 205b can provide a buffer between the support frame 106 and the main frame 101. At this time, the support frame 106 squeezes the airbag 205c, and under the connecting effect of the one-way valve 205d, the gas exhaust is controlled, and the gas in the squeezed airbag 205c is quickly squeezed and transported through the connecting pipe 205e. At this time, the gas is compressed and squeezed, and can pass through the wheel 204g to the gas attached to the side wall of the transmission cable. Impurities are cleaned to avoid interference and influence on the detection and inspection of the sensor 105. At the same time, during the driving process, the double-layer driving wheel 201d squeezes the movable rod 206c, which can drive the compression airbag 205c at the end of the movable rod 206c to squeeze and compress the air in the circulation tube 206b and transport it to the airbag 205c. At this time, gas and gas pressure can be provided for the exhaust at the wheel 204g. Through the movement of the movable rod 206c and the cooperation of the air inlet 206e, the intake and compression exhaust process of the air in the circulation tube 206b can be completed.

[0042] In summary, by cleaning the residual impurities on the surface of the transmission line with the wheel 204g, it is possible to prevent the impurities on the surface of the transmission line from interfering with the broken strand inspection process of the transmission line, and at the same time prevent the attachments from affecting the use of the transmission line and causing corrosion problems.
