[0035] Working principle: When the gate is in use, the staff only needs to control the electro-hydraulic push rod 51 to extend, so that the electro-hydraulic push rod 51 can drive the gate baffle 4 to move down and close through the connecting seat 52, so as to block and store water in the upstream river channel of the irrigation area. When the electro-hydraulic push rod 51 is controlled to retract, the electro-hydraulic push rod 51 can drive the gate baffle 4 to move up and open through the connecting seat 52, so that the water in the upstream river channel of the irrigation area can be released. During the release process, the Doppler ultrasonic flowmeter 53 in the river water will measure the water flow velocity and flow in the river and transmit it to the external measurement and control system in real time. At the same time, the ultrasonic water level meter 54 can measure the water level in the river channel below the irrigation area and transmit it to the external measurement and control system in real time, so that the staff can The staff records the water level, water flow and flow rate in the irrigation area river channel through the external measurement and control system, so that the staff can accurately control the opening and closing time of the gate baffle 4 according to the values of these water level, water flow and flow rate, so that the gate has the integrated measurement and control capability; in the later use process, when the ultrasonic water level meter 54 needs to be inspected and maintained, the staff only needs to control the driving motor 27 to reverse, so that the driving motor 27 can drive the worm gear 28 to rotate clockwise through the worm 26 (the clockwise rotation perspective here is a top view), and the clockwise rotating worm gear 28 will drive the extension plate 23 to swing to the left through the connecting shaft 29, and then the extension plate 23 drives the connecting boom 21 and the ultrasonic water level meter 54 to swing to the left together. When the extension plate 23 swings to the left in place (reference Figure 3 ), the driving motor 27 can be stopped. At this time, the staff only needs to stand by the river channel in the irrigation area to disassemble, maintain and overhaul the ultrasonic water level meter 54, and the staff only needs to loosen the fixing screw 25 with the help of an external wrench, and then the connecting boom 21 can be lifted up by pulling the handle 211, so that the connecting boom 21 drives the Doppler ultrasonic flowmeter 53 to move up together. At this time, the staff can disassemble, overhaul or maintain the Doppler ultrasonic flowmeter 53 together; when the overhaul is completed, the staff first moves the connecting boom 21 up and down to adjust the use height of the Doppler ultrasonic flowmeter 53 to the required height, and then tightens the fixing screw 25 with the help of an external wrench to prevent the connecting boom 21 from moving up and down again, and then controls the driving motor 27 to rotate forward, so that the worm gear 28 drives the extension plate 23 to swing to the right to its original position through the connecting shaft 29 (reference Figure 1 ) so that the ultrasonic water level meter 54 and the Doppler ultrasonic flow meter 53 can continue to monitor the water level and flow rate of the irrigation area river.
