Description
Technical field
The utility model relates to a kind ofly to be measured mountain region hydrology rainfall and forms the device of measuring flow behind the runoff, specifically a kind of domatic face of land flow measurement device.
Background technology
It is very extensive that current water level and flow current measured technology have been used, particularly at bigger rivers and lakes, uses comparatively outstanding.But aspect the particularly domatic less rainwash of domatic rainwash, what carry out is not very fast.Current that rainwash refers generally to be formed by precipitation or ice dissolution, flow into river, lake or ocean along the different paths in basin.Rainwash is important step of hydrology round-robin, is the basic factor that the river hydrologic regime changes.Run-off is one of fundamental of water balance.The seasonal variations of Different Forest type year flow path surface is summer＞spring＞autumn＞winter, and is consistent with the seasonal variations trend of rainfall amount.The different synusia features of forest have complementarity and inhibition to the influence of flow path surface, are subjected to influencing jointly of forest community composition, structure and growth.Year flow path surface is subjected to ecologic environment and combined influences such as forest land topsoil characteristic and vegetation, and flow path surface increases, reduces with the rising of height above sea level with the increase of the gradient.
Compare with the small watershed of not administering, the comprehensive regulation makes small watershed produce big vast number of times minimizing, and rainwash modulus and runoff duration shorten.Especially the most remarkable with short of rain year, analyze forest and annual flow relation, point out that the quantity of precipitation in basin, forest zone is big, reduce on the contrary but show runoff significantly because of infiltration capacity, surface runoff coefficient also increases with infiltration capacity and reduces.Bringing soil erosion under control has regulating action to rainwash.The comprehensive regulation increases the interannual variability of small watershed rainwash modulus; Instantaneous delivery and crest discharge are reduced so that disappear, thereby can reduce flood discharge, reduce flood harm and prevent the erosion of soil; In water and soil conservation lagged behind the small watershed runoff yield start time.
Existing flow measurement device has T shape face of land flow measurement instrument; it is a cylinder-like structure; the sensing part is in the centre position of cylinder; the cylinder traverse is in the face of land; and cylinder placed under the face of land 1/3rd position; be provided with the intensive 2mm water inlet aperture of 4～5 rows at cylinder and contact site, the face of land; owing to do not stop the screen pack of foreign material; very easily cause the into little hole plug of water; when getting the runoff sample in addition, flow measurement instrument integral body in the face of land must be taken out, after the runoff sample is poured out at every turn; reinstall one again and show the flow measurement instrument everywhere; moreover this device itself is not taked safeguard measure to rainfall, and when rainfall, rainwater can flow down along the cylinder top; directly in the 2mm aperture flowed into the sample tube, its measuring accuracy can produce different errors according to the size of rainfall amount.
The utility model content
At above shortcomings part in the prior art, the technical problems to be solved in the utility model provides a kind of both observation conveniently, improves measuring accuracy again, and the low face of land flow measurement device of cost.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of domatic face of land of the utility model flow measurement device comprises runoff collecting board, sample collecting pipe and gathering barrel, and wherein one side of runoff collecting board links to each other with the sample collecting pipe, and the two ends of sample collecting pipe are provided with shutoff; The gathering barrel upper entrance is provided with shutoff, and the bottom is provided with valve; Sample collecting pipe one end is communicated with by the water outlet sebific duct with the gathering barrel inlet; Above-mentioned each parts all are located under the rainproof protective cover.
In runoff collecting board front, be provided with screen pack in addition on sample approach axis domatic; The bucket wall of described gathering barrel is provided with scale mark; Described runoff collecting board, sample collecting pipe and gathering barrel all adopt the PVC material; Described rainproof protective cover is that metal material is made; be rectangle, screen pack and sample collecting pipe are all covered, two crooked chisel upper ends that described rainproof protective cover front end is fixed in screen pack are respectively equipped with the bolt of fixing rainproof protective cover; the rear end is overlapped on gathering barrel top, during installation before high back low.This domatic face of land flow measurement device is a plurality of, alternate layout domatic.
The utlity model has following beneficial effect and advantage:
1. the utility model can directly be measured the rainwash under various different gradient, the length of grade.Because of volume is little, any topography and geomorphology all can be measured, be applicable to various small sizes, can establish single-point and multiple spot laying, precision height, utilization factor height, applied range, be the ideal equipment of mobile footpath, mountain region flow measurement.
2. the utility model is made with easy for installation, and measurement accuracy is better, cost is lower, is suitable for not having the outlying area popularization of condition of power supply.
