Description
Technical field
The present invention relates to a kind of agricultural irrigation channel water consumption measurement ensures the structure and method of full packages, belong to water conservancy industry stream
Amount monitoring technical field.
Background technology
At present, in water conservancy industry, agricultural irrigation Jing measures the water yield of channel frequently with effusion meter, as effusion meter is to utilize
Flow velocity/area-method, in order to ensure that the area for flowing through pipeline is determination value, it is desirable to which aqueduct is full pipe condition, but, it is actual to answer
With in, when irrigation canal position is relatively low, the water outlet Jing of pipeline can not often reach full pipe condition, and the flow accuracy of effusion meter cannot
Ensure, which greatly limits the application of effusion meter.
The content of the invention
It is an object of the present invention to provide a kind of agricultural irrigation channel water consumption measurement ensures the structure and method of full packages, using in stream
The overfall higher than edge on effusion meter pipe outlet is set up in gauge exit, and the water in pipeline is necessarily be greater than on pipe outlet along
Overfall can be overflowed across and enter irrigation canal, it is ensured that the water in pipeline is in full pipe condition, so as to solve exist in background technology
The problems referred to above.
The technical scheme is that：
A kind of agricultural irrigation channel water consumption measurement ensures the structure of full packages, comprising irrigation canal, water in a canal, overfall, pipeline and stream
Gauge, effusion meter are matched on pipeline, and pipeline stretches into irrigation canal, and overfall is arranged on the outlet that pipeline stretches into irrigation canal
Place.
Slot is carried in the middle of the overfall, is inserted with pluggable water fender in slot.
Pluggable water fender in the middle of the overfall in slot, it is highly concordant with overfall, or it is less than overfall；Institute
The height for stating overfall and pluggable water fender necessarily be greater than the upper edge of pipeline；
A kind of method that agricultural irrigation channel water consumption measurement ensures full packages, using setting up higher than flowmeter tube at flowmeter outlet
The overfall on the upper edge of road outlet, the water in pipeline to necessarily be greater than and enter irrigation canal along just overflowing across overfall on pipe outlet,
Ensure that the water in pipeline is in full pipe condition.
Concrete step is as follows：
1. effusion meter is matched on pipeline, and pipeline stretches into irrigation canal, and overfall is arranged on the outlet that pipeline stretches into irrigation canal
Place；
Slot is carried in the middle of the overfall, is inserted with pluggable water fender in slot；
The irrigation canal, water in a canal, overfall, pipeline, effusion meter, to can be inserted into water fender be visible known technology on the market；
2. in the middle of the overfall in slot, the pluggable water fender being inserted with, the height that can be inserted into water fender can be with overfall
Concordantly, it is also possible to less than overfall；
3. the height of the overfall and pluggable water fender necessarily be greater than the upper edge of pipeline；
4. the water in a canal is flowed out from pipeline, is overflowed across；
5. due to can be inserted into the upper edge of the height higher than pipeline of water fender, water must be overflowed across at the top of pluggable water fender or overfall
Irrigation canal could be entered, therefore water is necessarily higher than the upper edge of pipeline；
6. due to pipeline in upper edge less than can be inserted into water fender height, water in a canal must overflow across pluggable water fender, so as to protect
The upper edge of card water in a canal pipeline, that is, ensure full packages.
When pluggable water fender is extracted out from overfall, the drift in pipeline and on front side of overfall can just be rushed at down
Trip, so that complete desilting.
Using the present invention, can ensure that aqueduct is in full pipe condition by overfall, meet the use of effusion meter
Condition so that in agricultural irrigation occasion, in the case that water level is relatively low, effusion meter can be used in a large number, be the agricultural of low relief area
Metering is irrigated there is provided effective means.Extracting out and can be inserted into water fender, desilting is completed using current, desilting process is simple.

Specific embodiment
Below in conjunction with accompanying drawing, by embodiment, the present invention will be further described.
A kind of agricultural irrigation channel water consumption measurement ensures the structure of full packages, comprising irrigation canal 1, water in a canal 2, overfall 3, pipe
Road 4 and effusion meter 5, effusion meter 5 are matched on pipeline 4, and pipeline 4 stretches into irrigation canal 1, and overfall 3 is arranged on pipeline 4 and stretches into filling
Irrigate the exit of channel 1.
Slot is carried in the middle of the overfall, is inserted with pluggable water fender 6 in slot.
Pluggable water fender in the middle of the overfall in slot, it is highly concordant with overfall, or it is less than overfall；Institute
The height for stating overfall 3 and pluggable water fender 6 necessarily be greater than the upper edge of pipeline 4.
