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
The invention belongs to Snowmelt runoff simulation field inspection field, particularly a kind of snow deposit temperature observation system.
Background technology
Periodicity, aperiodicity variation along with expanding economy and global environment, various frequent natural calamity occur, and the loss that it causes is also in continuous increase, wherein, flood damage is considered in world wide that outburst is the most frequent, also one of destructive disaster of tool simultaneously.Snowmelt flood refers to the flood being formed by snow melting, and seasonal snowmelt runoff is the important water resources composition part in western China.Physical process, snowmelt flood is more complicated compared with rainfall flood, because generally speaking snow melt rate is less than rainfall intensity, snow melt lasts and is greater than rainfall duration, snow lid has the stagnant effect of holding to melt water simultaneously, so flood volume is big vast with the snow that rain flood flood volume equates, its crest discharge is often low compared with rain flood crest discharge, and the duration of flood is long compared with the big vast duration of flood of rain, by the snow flood graph that snowmelt runoff graph superposition forms day by day, often there is obvious diurnal variation.
Climatic environment changes the variation that causes Basin Rainfall and runoff, River Basin Hydrology situation is developed day by day remarkable, and then occurs a series of regional shortage of water resources and big vast drought evil.Therefore in the urgent need to the research of deep reinforcement Snowmelt runoff simulation monitoring, to improve water resources management and hazard forecasting level, guarantee the sustainable utilization of water resource.And the field inspection hydrology, meteorological process need expend a large amount of manpower and materials for a long time, therefore need the crucial hydrologic process in systematic study basin.Snow deposit temperature regime is related to product concentration time and the peb process of snowmelt runoff, so the present invention can strengthen the precision that snow deposit temperature observation can be strengthened Snowmelt runoff simulation, improves Forecasting Snowmelt Runoff level, for water resources management provides strong decision-making foundation.
Summary of the invention
The object of this invention is to provide snow deposit temperature monitoring system, to realize different depth, dynamically long sequence snow deposit temperature observation in real time, thereby carry Snowmelt runoff simulation effect forecast precision.
Not enough for prior art, the invention provides a kind of snow deposit temperature observation system.
A snow deposit temperature observation system arranges bracing frame on pedestal, and a plurality of composite plates are set on support frame as described above, and described a plurality of composite plates are fixed on bracing frame by set bolt respectively, and 1 temperature sensor is set respectively in described a plurality of composite plates.

Accompanying drawing explanation
Fig. 1 is snow deposit temperature observation system architecture schematic diagram of the present invention;
Number in the figure: 1-pedestal; 2-bracing frame; 3-set bolt; 4-composite plate; 5-temperature sensor.
Embodiment
The invention provides a kind of snow deposit temperature observation system, below in conjunction with the drawings and specific embodiments, the present invention will be further described.
A kind of snow deposit temperature observation system, bracing frame 2 is set on pedestal 1, a plurality of composite plates 4 are set on support frame as described above 2, and described a plurality of composite plates 4 are fixed on bracing frame 2 by set bolt 3 respectively, in described a plurality of composite plates 4,1 temperature sensor 5 are set respectively.
Described pedestal 1 is sandstone cement block mixing pedestal.
Support frame as described above 2 is stainless-steel tube.
Described composite plate 4 is composited aluminum and plastic decking.
Described temperature sensor 5 is TP03 temperature sensor.
Embodiment 1
A snow deposit temperature observation system, as shown in Figure 1, this system comprises pedestal 1, bracing frame 2, set bolt 3, composite plate 4, temperature sensor 5 to its apparatus structure.
The cement block that the volume that the sand that pedestal 1 in the present embodiment is is 3:1 by mass ratio and stone are built is 300mm * 300mm * 600mm, bracing frame 2 is the stainless-steel tube of the thick 3mm of diameter 25mm, it is fixed on pedestal 1, forms snow deposit temperature observation system basic boom.Heavy wall stainless-steel tube is drawn materials easily, corrosion-resistant shock-resistant, has guaranteed the long-time non-maintaining property of system, and the height of stainless-steel tube depends on the historical maximum snow depth of installing zone.The cement block that sandstone are built has guaranteed the firm of whole system as pedestal, makes this system avoid being subject to the impact of snowstorm, has guaranteed the stability of system architecture.
Composite plate 4 is the long composited aluminum and plastic decking of the thick 300mm of 4mm, and it is fixed on stainless-steel tube by set bolt 3, residue length 200mm after installing.Composited aluminum and plastic decking lower temperature resistance is good, intensity is high, easily maintenance, has very good processability, disconnected hot and excellent fire protecting performance, and plasticity is good, impact resistance, and be easy to on-the-spot processing.
Temperature sensor 5 is TP03 temperature sensor, and it is fixed on composited aluminum and plastic decking, because the disconnected thermal behavior of composited aluminum and plastic decking is good, has guaranteed the measuring accuracy of temperature sensor to snow deposit temperature.TP03 type temperature sensor adopts stainless steel casing water-tight, has good long-time stability, should not be subject to the impact of the environmental factors such as dust, chemical gas, and low temperature resistant precision is high, has guaranteed extremely frigid zones snow deposit continuously measuring temperature.TP03 type temperature sensor is collected the snow deposit temperature apart from earth's surface 10cm, 20cm, 30cm, 40cm, five height of 50cm, records different depth snow deposit temperature conditions, as shown in Figure 1 temperature sensor 5 parts.The external same temperature data storage processing of all temperature sensors 5 system, the external solar panel power supply of temperature data stores processor system, to complete the observational record of snow deposit temperature and processing.
