The invention discloses a solar driven gate and belongs to the technical field of irrigation. The gate comprises a waterproof control box, a flashboard, flashboard sliding chutes, a door-type gate frame, two driving screws and bearing nuts; a power source, a motor, a synchronizer, a worm gear reducer, and a solar panel electrically connected with the power source are arranged in the waterproof control box; the door-type gate frame is fixed on canal banks on two sides of a canal, and the bottom of the door-type gate frame is flush with the bottom of the canal; the flashboard sliding chutes are fixed on left and right sidewalls of the door-type gate frame and two left and right sides of the flashboard are inserted into the flashboard sliding chutes; the waterproof control box is fixed on the top of the door-type gate frame; the bearing nuts are fixed on the top of the flashboard; upper ends of the driving screws are connected with the worm gear reducer, while lower ends of the driving screws are in threaded connection with the bearing nuts; the solar panel powers the power source and drives the motor to run; the synchronizer synchronously transmits the driving force of the motor to the worm gear reducer and drives the driving screws to rotate in the bearing nuts, thereby putting the flashboard in up-and-down motions in the flashboard sliding chutes. The solar driven gate is low in energy consumption.
