Description
Technical field
The utility model belongs to agricultural wate research water balance technical field, relates to a kind of miniature right-angle weir device for slope runoff quantitative determination.
Background technology
Weir refers in unhurried current open channel that arranging weir wall or both sides restraints the dash facility that the hydraulic structures such as narrow abutment wall are formed, and is mainly used in the water level or the metering overcurrent flow that control river or channel.
At present, agricultural, forestry and water conservancy measure the facility of slope runoff amount, and its principle is all water level based on measuring set pond and flow, then by the calculated sluice amount of stream weir experimental formula, finally obtains the change of the seasonal effect in time series water yield and flowing water total amount.Prior art is mainly used in: (1) hydraulic engineering: build fixing large-scale stream weir, is mainly used in measuring the larger open channel of flow and irrigates or reservoir spillway; (2) agricultural and the research of forestry water balance: build small-sized fixed flow weir, is mainly used in measuring compared with certain area gathering ground of low discharge or the water yield of fixed-area sloping surface runoff field.These technology are mainly applicable to the rough estimation compared with large discharge, and inadequate to the estimating precision compared with rill weir, are not suitable for measuring fixed-area slope runoff amount and studying water balance.
Summary of the invention
The utility model is in order to overcome the deficiencies in the prior art, special in slope runoff, there is provided one can for a long time, fixing, continuously, automatically, monitoring water level and flow, simplify the operation step, greatly improves the miniature right-angle weir device for slope runoff quantitative determination of the accuracy of monitoring.
To achieve these goals, the technical solution of the utility model is as follows:
For a miniature right-angle weir device for slope runoff quantitative determination, it comprises filtering ponds, filtering ponds baffle plate, steady boom, water collecting basin; Described filtering ponds are higher than water collecting basin, and described filtering ponds baffle plate is arranged between filtering ponds and water collecting basin, is evenly equipped with through hole above filtering ponds baffle plate; The outside plate of described water collecting basin is provided with right angle crest of weir.
Be provided with steady boom in above-described water collecting basin, water collecting basin be divided into one-level water collecting basin and secondary water collecting basin; Described steady boom is evenly equipped with through hole.
Cell is provided with in above-described secondary water collecting basin; Be equipped with through hole below the pair of side plates that described cell is parallel with steady boom, cell formed with secondary water collecting basin and is communicated with.
Automatic gauge is provided with in above-described cell.
During use, after slope runoff flows into filtering ponds, silt precipitates in filtering ponds, and when filtering ponds middle water level raises, water will flow in one-level water collecting basin by through hole on filtering ponds baffle plate; When filtering ponds middle water level is higher than filtering ponds baffle plate upper end, the water part in filtering ponds enters one-level water collecting basin by through hole, and a part overflows across filtering ponds baffle plate and enters one-level water collecting basin.When water enters one-level water collecting basin from filtering ponds, first be subject to the stop of steady boom and reduce the flow velocity of water, make slowly to flow into secondary water collecting basin with the water compared with kinetic energy by the through hole on steady boom, have automatic gauge continuous time recording pond middle water level in cell in secondary water collecting basin, after right angle crest of weir on secondary water collecting basin thin-walled flow out.The water level in water pool that automatic gauge monitors and the water yield change, and can calculate the time series dynamic change of fixed-area slope runoff amount according to existing experimental formula exactly.
Relative to prior art, the advantage that the utility model has and beneficial effect as follows:
1, this device is set with filtering ponds, for filtering the runoff of inlet mill weir, is set with a steady boom in water collecting basin simultaneously, and make the water yield mild, water surface water level is consistent, improves automatic gauge estimating precision.
2, this device mainly adopts right-angle triangle sharp-crested weir construction principle, and installation automatic gauge measures water collecting basin water level and the water yield changes, and can calculate the time series dynamic change of fixed-area slope runoff amount according to existing experimental formula exactly.
3, this device small, install simple, measure convenient, can for a long time, fixing, continuously, automatically, monitor water level and flow; Cost of manufacture is low simultaneously, and the used time is few, has good economic benefit and social benefit.
