Description

Technical Field

[0002] A runway is a long strip of ground for aircraft takeoff and landing. Placing a variety of sensors and monitors on the runway can monitor and sense the temperature, water accumulation, ice accumulation, visibility, etc. of the runway. Currently, the monitor needs to be fixed at a high place by a vertical pole, which makes it inconvenient to repair it. The technical document with the prior art publication number CN220063112U provides an Internet of Things monitor for monitoring water accumulation on airport runways. The design of the electric lifting rod, operation panel, radar detector, PLC controller, alarm light and voice announcer of the device, on the one hand, when repairing and replacing the upper parts, the electric lifting rod can be directly lowered, avoiding the use of ladders, improving the safety during maintenance, and the electronic display screen can be raised to reduce the probability of the device being submerged, thereby improving the use effect of the device.

[0003] In view of the above-mentioned related technologies, the inventor believes that although the electric lifting rod can be raised and lowered to inspect and replace the upper parts, it is impossible to place the connecting wires of the equipment inside the rod for protection, resulting in the connecting wires always being outside, which is easy to accelerate the loss of the connecting wires. Therefore, we propose an autonomous sensing device for runway ice accumulation. Utility Model Content

The fixed rod 1, the adjusting rod A2, and the adjusting rod B3 all have a hollow structure. The connecting line of the distribution cabinet 4 can pass through the adjusting rod B3, the adjusting rod A2, and the fixed rod 1 and then be connected to the ground. Both ends of the worm 12 are connected with a turning handle. When the worm 12 is rotated, the worm wheel 11 drives the chain 8 to rotate, and the chain 8 drives the two gears 9 to rotate. The gear 9 cooperates with the rack 10 to drive the adjusting rod A2 to rise and fall on the fixed rod 1, and the adjusting rod B3 is adjusted on the adjusting rod A2, so that the distribution cabinet 4 is driven to descend, which is convenient for its inspection and maintenance.

[0026] The power distribution cabinet 4 is linearly connected to the visibility meter 5, the camera 6 and the sensors embedded in the runway. The sensors monitor rain and icing on the runway surface and transmit the data to the control module in the power distribution cabinet 4.
