Embodiment

With reference to accompanying drawing, a kind of gate control and current surveying device, include gate pier 1, gate 2 and sluice flour slab 5, it is characterized in that: gate pier 1 arranges Steel Truss work bridge 6, the two ends of Steel Truss work bridge 6 are individually fixed on gate pier 1, motor 7 is arranged on Steel Truss work bridge 6, it is fixed on vertical shaft buttress 13 bottom vertical shaft 3, the top of vertical shaft 3 is fixedly connected with the crossbeam of Steel Truss work bridge 6, the middle fixed bias circuit 4 of gate 2, rotation axis 4 is sleeved on vertical shaft 3, stationary drive gear 10 on the vertical pivot 9 of motor 7, the end winding support of rotation axis 4 has from gear 15, driving gear 10 is meshed with from gear 15, gate 2 and gate pier 1, sealing 8 it is equipped with between sluice flour slab 5, sluice flour slab 5 is connected by a point seam 12 with vertical shaft buttress 13, divide in seam 12 and establish sealing 8, bezel locations at gate 2 arranges multiple first flow rate sensor 11 along height direction, gate pier 1 arranges multiple second speed sensor 18 and water level sensor 16 along height direction, gate pier 1 arranges block 14, it is used for stopper gate 2, controller 17 is arranged on Steel Truss work bridge 6, it is connected with motor 7 by cable. described motor 7 utilizes electric machine support 19 to be fixed on Steel Truss work bridge 6.

Gate 2 adopts double-sided glass steel composites structure. The multiple flow rate sensors 11 being arranged on gate 2 are caused along gate edge, vertical shaft 3 by cable and are connected to controller 17 on Steel Truss work bridge 6. Cable on gate is all closed in the middle of two-sided panel. Be arranged on the multiple second on gate pier 1 speed sensor 18 and water level sensor 16 by different cables along gate pier 1 edge, Steel Truss work bridge 6 be connected to controller 17.

When water crossed by channel, according to gate angle of rotation and channel width, it is possible to calculate water-carrying section width B; According to the signal that the first flow rate sensor 11 and second speed sensor 18 record, the mean flow rate V of channel can be obtained through signal processing; According to the signal that water level sensor 16 records, the depth of water H of channel can be obtained through signal processing. Accordingly, according to formula Q=V.B.H, the water flow Q of channel can be calculated.

During normal dash, gate 2 is perpendicular to current direction, and gate 2 is fixed by block 14. When water opened by gate 2, pressing the starting gate push button A on controller 17 panel, motor 7 is in standby state; Pressing the button B on controller 17 panel, motor 7 drives driving gear 10 to rotate by vertical pivot 9, driving gear 10 by driving gate 2 to rotate counterclockwise arbitrary angle from gear 15, channel water. By the display screen F on controller 17 panel, managerial personnel just can observe gate angle of rotation when being water, water flow. Press the water level the Show Button D on controller 17 panel, it is possible to display channel water level; Press flow velocity the Show Button E, it is possible to display channel flow velocity. When gate 2 rotates 90 degree, channel is spacious let out water. When gate needs to close, pressing the closed shutter push button C on controller 17 panel, motor 7 reverses, and drives driving gear 10 to rotate by vertical pivot 9, and driving gear 10 is by driving gate 2 to rotate clockwise from gear 15, and gate is slowly closed. When gate 2, to go back to 90 degree vertical with current direction, can recover dash.
