Description

Technical Field

[0001] The present invention belongs to the technical field of hydraulic gate design, and in particular relates to a manual opening and closing device for an integrated intelligent gate. Background Art

[0002] The integrated smart gate adopts multi-level linkage control, which can collect information such as the gate opening height, upstream and downstream water levels and operating status in real time, and send it to the control center through the remote 3G / 4G network. The control center will uniformly dispatch all gates. Through the multi-level linkage control of the upstream and downstream gates of the channel, the optimal allocation and scheduling of water resources can be achieved, thereby realizing water supply on demand, and thus achieving real-time and accurate measurement of the channel water conditions (such as water levels before and after the gates, gate opening and flow), and ultimately achieving the goal of water saving through downstream control, optimized scheduling, and reduction of irrigation water use.

[0003] The integrated smart gate consists of a gate, water level sensor, opening sensor, DC motor, transmission mechanism, controller, solar panel and communication board. It integrates water level and flow data collection, gate remote automation control, solar drive, wireless communication and other complete functions of intelligent measurement and control. The integrated smart gate device has been widely used to realize intelligent control and water scheduling of the canal network, optimize irrigation water resource allocation, and improve channel irrigation efficiency.

[0004] In the current use of integrated smart gates, if extreme conditions such as insufficient solar energy collection occur, the gates need to be opened and closed manually, such as Figure 5 As shown, the existing gate opening and closing device is as follows: a DC motor 11 is configured outside the transmission shaft 10 of the transmission mechanism, the DC motor 11 drives the worm gear 13 through the pulley 12, and the worm gear 13 drives the transmission shaft 10 to rotate to realize the opening and closing of the gate, and the worm shaft end of the worm gear 13 is provided with a spline shaft 14 for connecting the crank to realize manual operation of opening and closing the gate; when the speed of the reducer configured for the DC motor 11 is relatively large, the manual cranking torque is large when operating the crank, and it may even fail to move.

[0005] In addition, the gate opening sensor is arranged at the output shaft end of the DC motor 11. Since the motor rotates at a high speed, the acquisition of the sensor signal is unstable.

[0006] In order to achieve a reasonable reduction in the hand-cranking torque, to realize flexible movement and accurate sensor signal acquisition, it is necessary to improve the design of the existing gate opening and closing mechanism. Summary of the Invention
