Description
Technical field
The present invention relates to a kind of horizontal shaft type sediment run-off table.
Background technology
The rainfall of water erosion community, runoff, silt observation experiment, it is the important channel of research Erosion and soil and water conservation benefit, also be one of important means of carrying out water and soil conservation value work, the infrastructure of carrying out district monitoring comprises community of catchmenting (wherein standard water erosion cell set pool projected area 100 square metres, dash encloses bank projected length 20 meters, width 5 meters), afflux groove and afflux pond (or afflux bucket) etc.Sight gauge measuring appratus mainly comprises rain gage bucket, device for fetching water from, baker, sky equality.
Wherein the main contents of water erosion community water and soil conservation observation comprise: rainfall amount, run-off and quantity of sand and mud.
Water erosion district observation common method: rainfall observation pluviograph or rain gage bucket observation.Run-off takes afflux pond method of direct observation (calculating according to afflux pool area and depth of water relation) or shunting sight gauge algorithm.Silt observation takes traction load (husky, grain stone) and suspended load (can suspend fine sand and earth) to ask total to calculate.Traction load takes airing weight method, suspended load filtering drying weight method.
Traditional runoff plots rainfall, runoff and monitoring sediment, its principle is simple, but observation, process and calculation procedure are numerous and diverse, and management operating cost is high.Observation subdistrict dash encloses bank and afflux groove etc., generally smears concrete by outside building brick, and build technique simply, engineering is also very little, easily reaches quality requirements.But afflux facility (afflux pond or afflux cylinder) is built with regard to more complicated, one is collection pool volume size issue, if met 24 hours heavy rain most torrential rain footpath stream calculation by 5 years one, the volume in afflux pond at least wants 5 cubic metres, and quantities is large, and quality and precision are difficult to ensure, if adopt afflux bucket or shunting bucket, investment is large, and cost is high, all needs every year to maintain.In operation, one rainfall event all needs technician's field observation rainfall amount, changes from remembering paper, water intaking water gaging, filtering drying is weighed, clean water collecting basin (bucket) etc., time-consuming, not only need special messenger's observation, also be difficult to raise administration and operation cost, therefore a lot of observation subdistrict, runs and just cannot support down less than several years, have to give up halfway.
In order to improve robotization and the accuracy of water erosion district monitoring, based on the improvement to conventional monitoring methods, Chinese patent CN103698159A discloses a kind of rainfall trigger-type runoff automatic sampler and method thereof, Chinese patent CN201607350U discloses a kind of low interference sheet flow sampler, equipment disclosed in above-mentioned two patents is all for the sampling of runoff section and monitoring sediment, but lacks the monitoring to run-off.Trace it to its cause, one is that the runoff of water erosion community contains a large amount of silt, and normally used flow detection monitoring equipment, as flowmeter, easily blocks, and requires that Start-up and operating performance flow is large; And the hand-held radar wave current meter, supersonic Doppler current meter etc. of subsequent development, can not with sampling and monitoring sediment hardware compatibility, need extra dose, this adds increased artificial and equipment investment cost.
Summary of the invention
The object of the present invention is to provide a kind ofly can to sample with silt, monitoring equipment compatibility, improve the accuracy of water erosion community water and soil conservation observation, robotization can realize the horizontal shaft type sediment run-off table that runoff monitors term continuously.
Based on foregoing invention object, the technical solution adopted in the present invention is as follows:
