Description

Technical Field

[0001] The utility model relates to the field of data transmission line protection for automatic weather stations, in particular to a data transmission line protection device. Background Art

[0002] An automatic weather station is a device that can automatically observe and store meteorological observation data. It is mainly composed of sensors, collectors, communication interfaces, system power supplies, transmission cables, etc. As the values ​​of meteorological elements change, the amount of electricity output by the sensing elements of each sensor changes. This change is collected by the data collector controlled by the CPU in real time. After linearization and quantification, the conversion from engineering quantity to element quantity is realized, and the values ​​of various meteorological elements including air pressure, temperature, humidity, wind direction, wind speed, rainfall, etc. are obtained.

[0003] Although the cables are now wrapped with better insulating materials and passed through PVC pipes, and the cables in the trenches are laid overhead to prevent rodent damage, corrosion or high and low temperature environmental factors, the PVC pipe joints are exposed to the outside, so there is still a risk of meteorological data transmission being interrupted or abnormal observation values ​​occurring due to rat bites or cable cuts.

[0024] When in use, the staff sets several groups of cables 13 inside the insulating sleeve 1, and then sets two groups of support mechanisms 14 at the two ends of the insulating sleeve 1 respectively, and at the same time, one end of the cable 13 passes through the support mechanism 14, and sets the double-layer protective net 2 on the outside of the insulating sleeve 1.
