Specific implementation mode
Further details of explanation is done to the present invention with reference to the accompanying drawings and detailed description, it should be appreciated that
Protection scope of the present invention is not restricted by specific implementation.
As shown, the assembly type weir in the utility model includes top weir plate and lower part weir plate, top weir plate and
Lower part weir plate is detachably connected, and selects to install or remove top weir plate according to actual range demand, top weir plate is
Trapezoidal weir plate equipped with trapezoidal notch 1, lower part weir plate are the triangle weir plate equipped with triangular notch 2, and trapezoidal weir plate can measure
The infiltration capacity of 10~300L/s, the infiltration capacity that triangle weir plate can measure 1~7 L/s will be upper when the infiltration capacity of dam is smaller
Portion's weir plate disassembles measurement, and when the infiltration capacity of dam is larger, top weir plate is installed measurement.
Lower part weir plate may include several triangular notches 2, if setting 2 or more triangular notch 2, adjacent two triangle
Deflector 7 is set between shape notch 2, using identical with the entirety weir notch side wall deflector of roughness 7 between each triangular notch 2
Separate, 7 length of deflector is 10 times or more weir heads.
It is connected using connecting rod 3 and connecting hole 4 between top weir plate and lower part weir plate, lower part weir plate and lower part weir plate connect up and down
It connects, top weir plate is equipped with triangular flanges 5 corresponding with lower part weir plate, and lower part weir plate is equipped with connecting rod 3, on the weir plate of top
Equipped with connecting hole 4 corresponding with lower link 3, when assembling two weir plates, connecting rod 3 is goed deep into carry out positioning company in connecting hole 4
