Description
Technical field
This utility model relates to seepage discharge fields of measurement, is specifically related to one and is automatically adjusted multistage weir.
Background technology
Weir, refers to and is located in channel, tank in order to measure the downflow weir of water flow, is the capital equipment of observation seepage discharge, and composition includes weir notch, weir weir plate, level measurement device.
Weir has free overflow and floods two kinds of fluidised forms of stream.In order to improve accuracy in measurement, free overflow should be adopted, but outlet downstream water level is had higher requirements by free overflow, the flow rate calculation formula of weir mostly is empirical formula, for making flow measuring accurate, the working condition of weir should be made to be consistent with the experiment condition of empirical formula, and therefore before the installing on weir and weir, the fluidised form of channel also answers conformance with standard condition, makes the standard weir with standard operating conditions.At present, the weir of enforcement is generally single-stage non-modulated type, it is desirable to weir outlet downstream height of water level can not go out stream mode by influence amount mill weir.
Current China partial amount mill weir level of tail water affects due to flood discharge, generating etc., and range of stage is relatively big, and water level is too high, often makes weir be become flooding stream from free stream, causes weir measurement error even cannot work relatively greatly.Conventional amounts mill weir sharp rises because solving the level of tail water, causes letting out etc. in flood outburst or dam needing most the critical period paying close attention to dam infiltration amount, and weir cannot work, it is impossible to dam safety behavior is run judge timely and effectively.The level of tail water sharp rises, and to cause weir cannot normal operation be problem demanding prompt solution, not yet retrieves effective solution at present.

Principle of the present utility model
Weir of the present utility model arranges the weir crest of weir of different elevation, each crest of weir one weir gate that can automatically turn on closedown of configuration on same weir weir plate according to level of tail water luffing, is formed and multistage is automatically adjusted weir.Weir downstream is configured with the liquid level meter of the monitoring level of tail water, when the level of tail water is raised to and affects respective amount mill weir crest of weir free discharge state, the motor controlling weir gate opening and closing is started working, until weir gate completely closes, weir upper pond level starts to raise, until higher one-level crest of weir, make crest of weir go out stream and continue to remain free state；When water level decreasing to next stage weir crest of weir goes out water level when stream is freely flow, corresponding for control one-level weir gate is automatically turned on by motor, upper pond level begins to decline, continue to work at low one-level crest of weir, make in weir current can under rational state free discharge, no matter how to change can normal operation for the level of tail water.Thus ensure that the seriality of the accuracy of observation of weir and monitoring materials.
The beneficial effects of the utility model are in that:
This utility model provides one and is automatically adjusted multistage weir, and this device can effectively adapt to the situation that level of tail water luffing is bigger.Rising along with the level of tail water, it is automatically switched off the weir gate at non-free stream crest of weir place, switch to higher leveled crest of weir to be observed, the fluidised form that guaranteed discharge mill weir crest of weir freely flows, it is prevented that become flooding stream, along with the level of tail water declines, automatically open up the crest of weir weir gate going out leakage completely that can freely flow, the crest of weir switching to low one-level is observed, it is to avoid cause weir upper pond level too high owing to crest of weir arranges too high, affects the seepage state of hydraulic structure.This device accuracy of observation is high, function rationally, simple in construction, easily operated.
