Description
Technical field
The utility model relates to the small-sized soil water evaporation measurement mechanism based on sun power, belongs to soil water evaporation field of measuring technique.
Background technology
Soil water evaporation is a ring important in nature water circulation, it is the important component part of Forestland evapotranspiration and Evapotranspiration of The Field, also be a main expenditure in the water balance in forest land and farmland, how accurately, measure easily the evaporation of forest land and agricultural land soil, resolve its factor of influence, not only have great importance for the aspect such as soil water content forecast, water resources management, and can provide certain technical support for the solution of woods water, agriculture water contradictory problems.
At present, the more employing lysimeter of the measurement of soil evaporation.Lysimeter is mainly divided into two kinds of large-scale lysimeter and miniature lysimeters.Large-scale lysimeter, due to features such as expensive and operation inconvenience, is affected its application; Miniature lysimeter adopts electronic scales timing to take the mass change of undisturbed soil, calculates soil evaporativeness.Because electronic scales is independent existence the outside lysimeter, and do not there is the function of the weight of recording, therefore need to observe personnel tracking monitoring, this causes observation personnel's workload large, and the defect that observed result precision is low, meanwhile, this mode can not get in time continuous soil evaporation data.
Summary of the invention
The utility model object is to need staff to coordinate Monitoring Data in order to solve existing small-sized lysimeter, and the low problem of monitoring result precision, and a kind of small-sized soil water evaporation measurement mechanism based on sun power is provided.
Small-sized soil water evaporation measurement mechanism based on sun power described in the utility model, it comprises measures outer barrel and measures interior bucket, and it also comprises LOAD CELLS, data acquisition unit, accumulator, charging adapter and solar panel,
Data acquisition unit, accumulator and charging adapter are fixed on the bottom of LOAD CELLS, LOAD CELLS arranges spirit-leveling instrument, LOAD CELLS is arranged between two parties at the bucket end of measuring in outer barrel, in measuring, bucket occupy the center that is placed on LOAD CELLS, the radial play of measuring bucket in outer barrel and measurement is less than 5mm, and solar panel is positioned over the area of illumination of measuring outer barrel outside;
The data input pin of the data output end connection data collector of LOAD CELLS, data acquisition unit and LOAD CELLS are all passed through storage battery power supply, the charging input end of accumulator connects the charging output terminal of charging adapter, and the charging input end of charging adapter connects the charging output terminal of solar panel.
It also comprises handle, and it is circular that handle is, and in the inner ring surface of handle is fixed on and measures, on the sidewall of bucket port, the outer rim of handle covers on the port of measuring outer barrel, and its external diameter is greater than the external diameter of measuring outer barrel.
In described measurement outer barrel and measurement, bucket is PVC bucket.
Advantage of the present utility model: the utility model has been realized the automatic measurement of the small-sized soil water evaporation in field, it adopts data acquisition unit to gather constantly the weight of the soil of the interior splendid attire of bucket in measurement, has realized the continuous coverage of soil evaporation data.What the gap of measuring interior barrel of outer barrel and measurement was arranged is as far as possible little, and can prevent, because the air ratio soil conduction temperature performance in interior outer barrel gap is strong, affects the temperature variation of soil in the interior bucket of measurement, and then affect the error between soil evaporation measured value and actual value.
Described measurement mechanism can independently be positioned over field environment, do not need to be equipped with staff simultaneously, because the fixing instrument that adopts connects the monitoring weight data that continues, removed external interference from, therefore effectively raise the precision of measurement result, and reduced staff's workload.
