[0002] A civil aviation airport is a designated area used exclusively for takeoff, landing, taxiing, parking and other activities of civil aviation aircraft. It plays an important role in promoting economic development. In the construction of civil aviation airports, weak current engineering refers to the general term for all electrical systems except the power supply system, including but not limited to communication systems, navigation systems, meteorological systems, fire protection systems, security monitoring systems, information display systems, etc. These systems usually require regular operation and maintenance inspections to ensure their normal operation and safety and reliability.

[0003] Existing detection devices are generally composed of a detection box and a detection head or a detection pen, etc. The detection head or the detection pen is connected to the detection box through a connecting line. The detection pen detects the circuit to be detected and then transmits it to the inside of the detection box. Various detection devices such as ammeters and voltmeters are usually arranged in the detection box, which are displayed on a display screen and various measurement parameters can be adjusted. However, since there are frequent takeoffs and landings of airplanes in the airport, the noise and vibration are relatively large, and some detection devices are provided with various heat dissipation ports for heat dissipation, which causes the electronic components inside the detection device to be vibrated and easily damaged for a long time, thus affecting the service life of the detection device. In order to solve this technical problem, the utility model proposes a civil aviation airport weak current engineering operation and maintenance detection device. Utility Model Content

The heat sink 304 is used to increase the contact area between the heat sink 301 and the air, thereby increasing the heat dissipation effect. The heat-conducting block 302 passes through the second sound insulation cotton 202, the device housing 1 and the first sound insulation cotton 201 in sequence. The material of the heat-conducting block 302 is copper, which has excellent thermal conductivity. A heat-conducting plate 303 is fixedly connected to the side of the heat-conducting block 302 away from the heat sink 301. The material of the heat-conducting plate 303 is copper and is in contact with the internal electronic components.

[0025] A first shock absorbing mechanism 4 is arranged below the device shell 1, and a second shock absorbing mechanism 5 is arranged below the first shock absorbing mechanism 4.

The heat is dissipated into the air through the heat dissipation plate 301 and the heat sink 304, thereby completing the heat dissipation, changing the original heat dissipation method through the heat dissipation holes to prevent sound from entering from the heat dissipation holes.
