Pipeline nondestructive testing device carried on unmanned aerial vehicle

Abstract

The invention discloses a pipeline nondestructive testing device carried on an unmanned aerial vehicle. The pipeline nondestructive testing device is characterized in that the pipeline nondestructive testing device comprises an unmanned aerial vehicle shell and an ultrasonic detector, an ultrasonic mounting groove is formed in the bottom of the unmanned aerial vehicle shell, the ultrasonic detector is mounted in the ultrasonic mounting groove, and upper supports are fixedly connected to the two sides of the unmanned aerial vehicle shell; a lifting mechanism is arranged on the upper support, a lower support is arranged at the bottom of the upper support, a heat dissipation plate is arranged at the top of the unmanned aerial vehicle shell, first heat conduction silica gel is arranged between the heat dissipation plate and the unmanned aerial vehicle shell, a cooling cover is arranged at the bottom of an inner cavity of the unmanned aerial vehicle shell, a miniature condenser is arranged on the outer wall of the cooling cover, anda first cooling pipe coiled around the inner wall of the cooling cover is arranged in the cooling cover. The device has the beneficial effects that the ultrasonic detector can be carried on the unmanned aerial vehicle, the detection range is enlarged, meanwhile, the heat dissipation effect is good, and the unmanned aerial vehicle is convenient to overhaul.

Description

technical field [0001] The invention belongs to the technical field of pipeline non-destructive testing, in particular to a pipeline non-destructive testing device mounted on a drone. Background technique [0002] Non-destructive testing refers to the use of changes in thermal, sound, light, electricity, magnetic and other reactions caused by abnormal internal structures or defects of materials without damaging or affecting the performance of the tested object and the internal organization of the tested object. , by means of physical or chemical methods, with the help of modern technology and equipment, to inspect the structure, nature, state and type, nature, quantity, shape, position, size, distribution and changes of the internal and surface of the test piece and test methods. [0003] With the development of UAV technology, the non-destructive testing ultrasonic detector is mounted on the UAV, which makes the detection range wider and the safety performance is higher. H...

AI Technical Summary

Problems solved by technology

[0003] With the development of UAV technology, the non-destructive testing ultrasonic detector is mounted on the UAV, which makes the detection range wider and the safety performance is higher. However, the existing UAV pipeline non-destructive testing device has the following problems: ( 1) After the drone flies for a long time, it will generate a lot of heat, which will cause the temperature of the drone to rise. If the heat is not transmitted to the outside world in time, it will affect the work of the ultrasonic detector, and in severe cases, the ultrasonic detector will be damaged. ; (2) It is inconvenient to disassemble the ultrasonic detector installed on the UAV, which is not conducive to the maintenance of the ultrasonic detector
