detailed description

Referring to the accompanying drawings, a gate control and flow measuring device includes a gate pier 1, a gate 2 and a gate bottom plate 5, and is characterized in that a steel truss working bridge 6 is arranged on the gate pier 1, and the two ends of the steel truss working bridge 6 are respectively Fixed on the gate pier 1, the motor 7 is set on the steel truss working bridge 6, the bottom of the vertical shaft 3 is fixed on the vertical shaft support pier 13, the top of the vertical shaft 3 is fixedly connected with the beam of the steel truss working bridge 6, and the middle of the gate 2 is fixed to rotate The shaft 4 and the rotating shaft 4 are set on the vertical shaft 3, the driving gear 10 is fixed on the vertical shaft 9 of the motor 7, the end of the rotating shaft 4 is fixed with a slave gear 15, the driving gear 10 meshes with the slave gear 15, and the gate 2 and the gate Water stop 8 is provided between pier 1 and gate bottom plate 5, gate bottom plate 5 and vertical shaft support pier 13 are connected by split 12, and water stop 8 is set in split 12, and multiple The first flow rate sensor 11, a plurality of second flow rate sensors 18 and water level sensors 16 are arranged on the gate pier 1 along the height direction, the stopper 14 is set on the gate pier 1 to block the gate 2, and the controller 17 is set on the steel truss to work On the bridge 6, it is connected with the motor 7 by cables. Described motor 7 utilizes motor support 19 to be fixed on the steel truss work bridge 6.

Gate 2 adopts double-sided FRP composite structure. A plurality of flow rate sensors 11 arranged on the gate 2 are connected to the controller 17 by cables along the edge of the gate and the vertical shaft 3 to the steel truss working bridge 6 . The cables on the gate are enclosed in the middle of the double-sided panel. A plurality of second flow rate sensors 18 and water level sensors 16 arranged on the gate pier 1 are connected to the controller 17 along the edge of the gate pier 1 and the steel truss working bridge 6 through different cables.

When the channel passes through the water, according to the gate rotation angle and the channel width, the cross-section width B can be calculated; according to the signals measured by the first flow rate sensor 11 and the second flow rate sensor 18, the average flow rate V of the channel can be obtained through signal processing; According to the signal measured by the water level sensor 16, the water depth H of the channel can be obtained through signal processing. Accordingly, according to the formula Q=V.B.H, the water flow Q of the channel can be calculated.
