Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 5 A flood control and drainage irrigation device includes a water discharge component for discharging water to irrigate farmland, an opening and closing component for sliding up and down to control water discharge is installed in the water discharge component, and also includes a support component arranged on the opening and closing component for corner guidance and rolling support for opening and closing gates, and a control component for controlling the opening and closing size of the gate by limiting the floating drop gate is arranged on the side of the bottom of the support component away from the closing component.

[0027] In this embodiment: the water discharge assembly includes a river bank 101, an irrigation channel 102 is arranged on one side of the river bank 101, a culvert 103 is arranged between the irrigation channel 102 and the river bank 101, and the culvert 103 is circular in shape. The water in the river bank 101 flows into the irrigation channel 102 through the culvert 103 to irrigate the farmland;

[0028] In this embodiment: the opening and closing assembly includes a gate frame 201, a gate plate 202 is slidably installed in the gate frame 201, a lifting block 203 is arranged on the gate plate 202, the lifting block 203 is welded to the gate plate 202, and the lifting block 203 drives the gate plate 202 to slide up and down along the gate frame 201 to control the opening and closing of the duct 103;

[0029] In this embodiment: the support assembly includes a fixed seat 301, a first pulley 302 and a second pulley 303 are symmetrically arranged on both sides of the fixed seat 301, a steel rope 304 is arranged between the first pulley 302 and the second pulley 303, four fixing ears 305 are symmetrically arranged at the bottom of the fixed seat 301, and fixing bolts 306 are arranged in the fixing ears 305. The fixed seat 301 is fixed to the river bank 101 through the fixing bolts 306 on the fixing ears 305, providing support for the steel ropes 304 on the first pulley 302 and the second pulley 303;

[0030] In this embodiment, the control component includes two support blocks 401 symmetrically arranged front and back, a limit frame 402 is arranged on the support block 401, a slide bar 403 is installed in the limit frame 402, a floating plate 404 is slidably installed between the two slide bars 403, a counterweight block 405 is arranged on the floating plate 404, a fixed block 406 is arranged on the counterweight block 405, the counterweight block 405 is circular in shape, and the counterweight block 405 is bolted to the floating plate 404. During the rainy season, the water level in the irrigation canal 102 rises, so that the floating plate 404 on the support block 401 moves upward along the slide bar 403 against the counterweight block 405. At this time, due to the steel rope 304 One end is connected to the counterweight block 405 through the fixed block 406, and the end away from the fixed block 406 is connected to the gate plate 202 through the lifting block 203. Therefore, when the counterweight block 405 rises, the gate plate 202 will pull the steel rope 304 under the support and guidance of the first pulley 302 and the second pulley 303 and move downward along the gate frame 201, gradually blocking the entrance of the culvert 103. When the floating plate 404 moves to the top of the limit frame 402, the gate plate 202 moves to the bottom of the gate frame 201, completely blocking the entrance of the culvert 103, preventing the water in the river bank 101 from continuing to flow into the irrigation channel 102, causing the water in the irrigation channel 102 to flood into the farmland.

[0031] Working principle: In the dry season, water in the river bank 101 flows into the irrigation channel 102 through the culvert 103 to irrigate the farmland; in the rainy season, the water level in the irrigation channel 102 rises, causing the floating plate 404 on the support block 401 to move upward along the slide 403 against the counterweight block 405. At this time, since one end of the steel rope 304 is connected to the counterweight block 405 through the fixed block 406, and the end away from the fixed block 406 is connected to the gate plate 202 through the lifting block 203, when the counterweight block 405 rises, the gate plate 202 will be between the first pulley 302 and the second pulley 303. The steel rope 304 is pulled downwardly by the support guide and moves downwardly along the gate frame 201, gradually blocking the entrance of the culvert 103. When the floating plate 404 moves to the top of the limit frame 402, the gate plate 202 moves to the bottom of the gate frame 201, completely blocking the entrance of the culvert 103, preventing the water in the river bank 101 from continuing to flow into the irrigation channel 102, causing the water in the irrigation channel 102 to flood into the farmland; during the movement of the steel rope 304, the fixed seat 301 is fixed to the river bank 101 by the fixing bolts 306 on the fixing ears 305, providing support for the first pulley 302 and the second pulley 303.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
