The flow sensors 3 are electrically connected, and the flow sensor 3 is used to detect the flow rate at the gate. The relevant signal can be fed back to the gate sensor 6, prompting the gate sensor 6 to control the operation of the servo motor 1 according to the liquid flow rate. When the liquid flow rate is large, the gate plate 2 can be opened and closed larger to facilitate the discharge of water. The output end of the servo motor 1 is fixedly connected to the transmission gear 10 through the transmission shaft 11. The center of the surface of the transmission gear 10 is connected to the bearing seat 8 through the rotating shaft. A sealing baffle 7 is provided on the gate plate 2.

The servo motor 1 drives the transmission gear 10 to rotate clockwise and counterclockwise, thereby driving the fixed rack 9 to make vertical linear motion, thereby conveniently driving the gate plate 2 to adjust the opening and closing size of the gate body 4.

[0019] A radar flow meter 14 is installed on the flow measuring sensor 3. The model of the radar flow meter 14 is SCJ-LL21, which is a high-precision non-contact flow measuring device. The radar flow meter 14 uses the velocity area method to measure the flow. The instantaneous flow Q = flow velocity V * flow area S is obtained. The flow area S is calculated by channel section data and water depth. A data transmission interface 12 is installed below the radar flow meter 14, which is convenient for computer transmission of its internal data. A data display screen 15 and a signal transmitting module 13 are installed on the front surface of the flow measuring sensor 3. The signal transmitting module 13 is connected to the signal receiving module set inside the data information monitoring platform 16 through a wireless signal.

[0021] The telemetry terminal RTU module 19 is responsible for the calculation. The telemetry terminal RTU has a built-in calculation formula. The downstream flow value is calculated by actually collecting the following parameter values. The formula relationship table is: Q=μObe√2gh, μO: flow coefficient, calculated according to the flow coefficient of the flat gate hole on the flat ground, μO=0.6-0.176e / h, generally 0.6; b: gate width (constant); e: gate lifting height (obtained by the opening meter); g: gravity acceleration 9.81m / s2 (constant); h: water level height of the water station (obtained by the ultrasonic level meter); Q: downstream flow, taking the environmental protection approved data, using the above measurement method, the flow measurement error of the integrated measurement and control gate is less than 5%.

[0022] Camera 20 is an industrial camera with intelligent behavior analysis functions such as motion detection, area intrusion, cross-border intrusion, object abandonment / disappearance, wandering, parking, fast movement, and crowd gathering, scene change detection, alarm linkage, etc. The gate control cabinet 26 displays and controls the gate of the current monitoring station, including the control of the gate opening, the relative position and the absolute position of the gate, displays and sets the flow measurement data calibration coefficient, the water level calibration coefficient, data transmission, etc. of the current monitoring station.
