Embodiment 1

[0022] A snow layer temperature observation system, its device structure is as follows figure 1 As shown, the system includes a base 1 , a support frame 2 , fixing bolts 3 , a composite board 4 , and a temperature sensor 5 .

[0023] The base 1 in this embodiment is a cement block with a volume of 300 mm × 300 mm × 600 mm poured from sand and stones with a mass ratio of 3:1. The support frame 2 is a stainless steel pipe with a diameter of 25 mm and a thickness of 3 mm, which is fixed on the base. 1, which constitutes the basic framework of the snow layer temperature observation system. The thick-walled stainless steel pipe is easy to obtain, corrosion-resistant and impact-resistant, which ensures the long-term maintenance-free performance of the system. The height of the stainless steel pipe depends on the historical maximum snow depth in the installation area. The cement blocks poured with sand and gravel are used as the base to ensure the stability of the entire system, whi...

Abstract

The invention belongs to the field of field observation of snowmelt runoff simulation, and particularly relates to a snow cover temperature observation system. According to the system, a plurality of temperature sensors which are high in sensitivity, resistant to low temperatures and low in power consumption are fixed on a composite board, the composite board is connected with a supporting frame, and the supporting frame is fixed on a ground cement base. The snow cover temperature observation system solves the difficult problem of temperature observation in different snow depths in plateau areas, achieves real-time dynamic observation of snow cover temperatures in different depths in a long sequence, improves the precision of parameter calibration in a snowmelt runoff simulation model, and greatly reduces the expenditure of scientific research funds.

Description

technical field [0001] The invention belongs to the field observation field of snowmelt runoff simulation, in particular to a snow layer temperature observation system. Background technique [0002] With the development of the economy and the cyclical and non-cyclical changes of the global environment, various natural disasters occur frequently, and the losses caused by them are also increasing. Among them, flood disasters are considered to be the most frequent outbreaks in the world. It is also one of the most devastating natural disasters. Snowmelt flood refers to the flood formed by the melting of snow. Seasonal snowmelt water is an important part of water resources in western my country. From a physical point of view, snowmelt floods are more complicated than rainfall floods, because generally speaking, the snowmelt rate is smaller than the rainfall intensity, the snowmelt duration is longer than the rainfall duration, and snow cover has a stagnation effect on meltwater...
