High voltage overhead transmission line line-inspection unmanned aerial vehicle photoelectric detection device

The invention relates to a high voltage overhead transmission line line-inspection unmanned aerial vehicle photoelectric detection device belonging to the technical field of power line inspection. The invention aims at solving the problem of single technology of the existing overhead transmission line line-inspection. The high voltage overhead transmission line line-inspection unmanned aerial vehicle photoelectric detection device mainly comprises an unmanned aerial vehicle, a GPS (global position system) inertial integrated attitude azimuth detection device, a damping device, a rotation detection nacelle, a ground data receiving processor and a controller. The high voltage overhead transmission line line-inspection unmanned aerial vehicle photoelectric detection device is characterized in that the GPS inertial integrated attitude azimuth detection device is arranged at the inner part of the unmanned aerial vehicle; the rotation detection nacelle is hung below the unmanned aerial vehicle by the damping device; a photoelectric stabilized platform is installed in the rotation detection nacelle; flexible combination of any two or more of a visible light camera, an ultraviolet ray imager and a full-digital dynamic thermal infrared imager and a laser ranging device are borne on the photoelectric stabilized platform; and the rotation detection nacelle is provided with a visible window. With the adoption of the high voltage overhead transmission line line-inspection unmanned aerial vehicle photoelectric detection device, a high voltage transmission line can be monitored, and a comprehensive and precise high voltage overhead transmission line line-inspection task is realized by combining interchange among a plurality of sensors.

Scroll cable detecting robot

The invention discloses a spiral line cable detecting robot which consists of a cart, an upper and a lower supporting hugging devices symmetrically distributed along the cable which are connected together. The robot is characterized in that the active cart is provided with a climbing device and a magnetic absorbing device; two supporting horizontal levers are provided with hugging devices; the climbing device includes a lithium battery fixed in the cart and a DC motor fixed on one side of the driving wheel in the cart; power of the DC motor is supplied by the lithium battery, and the DC motor drives the driving wheel of the cart to rotate by a drive axle, so as to drive the whole robot to spirally climb along a water transmission line of the cable; the hugging devices and the magnetic absorbing device work together to tightly press the driving wheel onto the surface of the cable. The climbing device can rotate for any degree relative to the cart, so as to adapt to the water transmission line with different thread pitch; power supply by the lithium battery is more suitable for the environment of high-altitude operation; the robot is also provided with a descending device, which is safer and more reliable in use. The invention has simple and reasonable structure, is convenient in maintenance, can have high climbing speed, is applicable in detection of the spiral line cable of large cable-stayed bridges as well as lamps and other rod types.
