Abstract
The utility model provides a detachable water conservation project small-flow seepage measuring device which is composed of a detachable weir plate (1), a flow guiding water channel (2), a measurer shell (3), a water containing funnel (4), a tipping bucket type flowmeter (5) and a pulse generation counter (6). A groove (10) and a sealing strip (11) are arranged on the lower portion of the weir plate (1) and matched with a V-shaped water outlet channel on a measuring weir, water is enabled to flow into the tipping bucket type flowmeter (5) through the flow guiding water channel (2) and the water containing funnel (4), and therefore the flow monitoring automatic counting purpose is achieved. The detachable water conservation project small-flow seepage measuring device is simple and convenient to mount and use, solves the transformation problem of the measuring weir, and improves seepage monitoring automation degree.
Description
Technical field
the utility model relates to the hydraulic safety monitoring device, is a kind of to water conservancy projectbuilding
monitoring measurement mechanism as dam body low discharge seepage flow.
Background technology
According to " safety monitoring of earth-rockfill dams technical manual " (SL80-94), by the size of seepage flow with collect condition, the method that the monitoring of hydraulic structure seepage flow is selected mainly contains:
One, be less than the appropriate to the occasion employing volumetric method of 1L/s when flow, in certain hour, by the collected water yield of container, calculate seepage flow;
Two,, when flow appropriate to the occasion employing weir method between 1～300L/s, the concise and to the point needle water level gauge that utilizes under the type of various weirs is exactly measured water level to calculate seepage flow;
Three, when flow is greater than 300L/s or be subject to the drop restriction can not weir be set, percolating water should be introduced to trench drain, adopt the velocity measurement method.
(1) underground workshop, dam at the initial stage of building up, the leakage of just holding phase and steady operation period differs greatly, all there are the initial stage of building up in many hydraulic structures, it is large just to hold the phase leakage, and the trend reduced year by year in the steady operation period leakage.In the monitoring point of some hydraulic structure, the leakage of steady operation period is even only 30% of the initial stage.Therefore with regard to existing the weir method that will measure larger flow to be transformed into, measure than the problem of low discharge volumetric method.
(2) the more and technology maturation of weir method and the spendable monitoring instrument of velocity measurement method, however while adopting volumetric method test low discharge, the careful degree of operator is had relatively high expectations, and when different personnel implement to test, the precision of reading is difficult to guarantee.The tradition volumetric method need to manually gather, reads, record data, and high to artificial degree of dependence, automatization level is low.
The utility model content
The utility model, for the problem of above-mentioned prior art, provides a kind of detachable low discharge seepage monitoring easy to use
measurement mechanism.
The utility model
detachable water conservancy project low discharge seepage flow measurement mechanismby detachable weir plate 1, diversion flume 2, measuring appliance housing 3, the funnel 4 that is filled with water, tipping bucket meter 5 and pulse generation counter 6, formed;
detachable weir plate 1 be V-arrangement, its shape andv-arrangement effluent trough a ' on weir a is consistent
, detachable weir plate 1bottom offers groove 10 and sealing strip 11, during use
the bottom of detachable weir plate 1 is passed throughgroove 10 and sealing strip 11 are connected with the V-arrangement effluent trough a ' ne-leakage on weir a,
the V-shaped part bottom of detachable weir plate 1 is connected with diversion flume 2, tipping bucket meter 5 is arranged in measuring appliance housing 3, the funnel 4 that is filled with water is arranged on the top of the interior tipping bucket meter 5 of measuring appliance housing 3, diversion flume 2 is guided funnel 4 tops that are filled with water into, on bottom in measuring appliance housing 3, the two ends, left and right of corresponding tipping bucket meter 5 arrange pulse generation counter 6, be provided with adjustable support leg 31 on the bottom surface of measuring appliance housing 3, set level to use measuring appliance housing 3 levels, make tipping bucket meter 5 exactly work.
the utility model is by detachable weir plate 1 He diversion flume 2 is guided to the upper water passed through of former weir a in measuring appliance housing 3, by the funnel 4 that is filled with water, injects tipping bucket meter 5,
tipping bucket meter 5two isometric triangle small rooms, when a small room water receiving, another small room is in waiting status, when connect infiltration volume reaches predetermined value, due to the Action of Gravity Field automatic overturning, in waiting status, another small room is in the water receiving duty, and left and right two struggle against always rotation in the water receiving state.
pulse generation counter 6consist of magnet steel and tongue tube, on the tipping bucket sidewall, magnet steel is housed, when it stirs with tipping bucket, from the other inswept dry type tongue spring tube that makes of dry type tongue spring tube, produce the break-make variation, dry type tongue spring tube of the every overturning of tipping bucket is just connected and is once sent a pulse signal.Pulse signal of every generation just represents certain water yield, realizes the purpose of flow monitoring Auto-counting.Can directly purchase CR10X data acquisition unit record unit time umber of pulse.
The utility model can be used in conjunction with existing weir a, fills simple and conveniently, solves weir transformation problem, easy to use, saves time, cost.Adopt tipping bucket meter and auto-counter to gather data on flows, improve the seepage monitoring automaticity.
