Description

Novel deep geothermal sensor sleeve of automatic weather station

Technical Field

The utility model relates to the technical field of meteorological detection equipment, in particular to a novel deep geothermal sensor sleeve of an automatic meteorological station.

Background

At present, most meteorological elements of a national meteorological observation station realize automatic observation (such as wind direction, wind speed, temperature, humidity, air pressure, rainfall, sunshine, frozen soil and the like), the fact that an observation sensor is replaced by an expiration and inspection is an important work, most meteorological element observation instruments are not troublesome due to the expiration and the replacement, time consumption is not too long, and meteorological observation data are not greatly influenced during the replacement. The only time of replacing the geothermal sensor is very troublesome, and the geothermal observation mainly comprises: shallow geothermal (0 cm, 5cm, 10cm, 15cm, 20cm, and deep geothermal (40 cm, 80cm, 160cm, and 320 cm). When the ground temperature sensor is replaced, each sensor communication line (about 7-18 m long) needs to be detached firstly, then passes through a PVC pipe which is buried under the ground and is provided with 6-7 turns, details are complicated, time consumption is long, workload is large in the ubiquitous weather station of the whole country, and instrument sensing data after replacement also needs a slow recovery process, so that representativeness, accuracy and comparability of observed data are affected. The replaced ground temperature sensor is inconvenient because the wiring terminals are removed and five wires are required to be connected to five wiring terminals of the verification instrument in a one-to-one correspondence manner when the ground temperature sensor is sent to an upper verification.

The situation is ubiquitous in the national weather station, so that the structure of the outer sleeve and the inner sleeve adopted by the wiring of the existing ground temperature sensor and the communication wiring mode are improved, a set of wiring terminals are not required to be removed when the sensor is replaced, the influence on ground temperature observation data due to long time consumption of replacing the sensor can be reduced, and meanwhile, the whole root-type deep ground temperature sensor sleeve which is convenient and time-saving in detecting the wiring of an instrument is very necessary.
