Problem.
In order to solve the above technical problems, the technical scheme is that：
A kind of adaptive triangular-notch weir, including weir plate, weir plate chute, embedded weir plate case, floating body and floating body case, the weir plate
Upper end be provided with triangle crest of weir, the embedded weir plate case is arranged in the soil layer below canal bottom, the weir plate chute it is upper
Portion is fixed in the side wall of water channel, and the weir plate chute bottom is fixed in the embedded weir plate case, the left and right of the weir plate
Both sides are inserted in the weir plate chute respectively, and the floating body case is arranged on corresponding to the weir plate chute in side wall, the floating body
Case is provided with the connected entrance connected with water channel in weir plate influent side, and the floating body is arranged in floating body case, and the floating body is by setting
The through hole put in weir plate chute is connected with weir plate, makes water on the certain weir of the weir plate holding by the buoyancy of the floating body
Position, so as to keep certain flow, and can be moved along the weir plate chute, and mobile height is less than the embedded weir plate case
Highly.
Wherein it is preferred to the contact position on the embedded weir plate case with the weir plate is provided with the first rubber layer.
Wherein it is preferred in addition to antiseepage cloth, the antiseepage cloth is coated at the top of the weir plate and the embedded weir plate
Box top.
Wherein it is preferred to the weir plate chute is provided with the second rubber layer.
Wherein it is preferred to the relative position of the weir plate and the floating body is adjustable.
Beneficial effects of the present invention：
1. the present invention enables weir plate to be maintained at certain height, that is, passes through the present apparatus by setting floating body in weir plate both sides
Downstream go out to flow stability of flow, it is simple in construction, it is not necessary to extra machinery is the adjustment that weir plate height can be achieved, cost compared with
It is low.
2. in the present invention, the relative altitude of weir plate and floating body is adjustable, by adjusting the relative altitude of the two, can adjust to
Downstream goes out flow, and the accurate measurement that various flow rate can be achieved is irrigated.
