[0021] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0022] In order to solve the problems existing in the background art, this application proposes the following technical solution: a gate opening and closing device for water conservancy projects, including a gate frame 1, and a gate plate 2 slidably connected inside the gate frame 1.

[0023] The top of the door frame 1 is rotatably connected to a nut sleeve 4, and the top of the gate plate 2 is fixedly connected to a threaded rod 3. The threaded rod 3 is coated with anti-corrosion paint and is threadedly connected to the nut sleeve 4. The top of the door frame 1 is fixedly connected to a fixed seat 8, and a rotating rod 7 is rotatably connected to the fixed seat 8. One end of the rotating rod 7 is fixedly connected to a worm gear 6, and a worm wheel 5 is fixedly connected to the outside of the nut sleeve 4. The worm gear 6 meshes with the worm wheel 5. The rotating rod 7 drives the worm gear 6 to rotate, and the worm gear 6 drives the nut sleeve 4 to rotate. Thus, through the meshing of the nut sleeve 4 and the threaded rod 3, the threaded rod 3 can drive the sliding plate of the gate plate 2.

[0024] In the specific design, a hand crank assembly is provided at one end of the rotating rod 7, an electric drive assembly is provided on the outside of the door frame 1, and a connecting assembly is also provided on the outside of the door frame 1. The electric drive assembly drives the rotating rod 7 to rotate through the connecting assembly.

[0025] The electric drive component is a motor 11. A threaded column 12 is rotatably connected to the outside of the door frame 1. A nut block 13 is threadedly connected to the outside of the threaded column 12. A fixing ring 15 is fixedly connected to the outside of the nut block 13. The fixing ring 15 is fixedly connected to the motor 11. A guide rod 14 is fixedly connected to the outside of the door frame 1. The guide rod 14 passes through the nut block 13. The connecting component includes a first bevel gear 9 and a second bevel gear 10. The first bevel gear 9 is fixedly connected to the rotating rod 7. The second bevel gear 10 is fixedly connected to the output end of the motor 11. The motor 11 drives the second bevel gear 10 to rotate. The second bevel gear 10 drives the first bevel gear 9 to rotate, thereby driving the rotating rod 7 to rotate. The rotating rod 7 drives the worm gear 6 to rotate. The worm gear 6 drives the nut sleeve 4 to rotate. When the gate 2 needs to be manually operated to lift or lower, the threaded column 12 is rotated, causing the nut block 13 to drive the fixing ring 15 to move downward. The fixing ring 15 drives the motor 11 to move downward, thereby disengaging the second bevel gear 10 from the first bevel gear 9.

[0026] The hand-cranked assembly includes a fixed block 16 fixedly connected to one end of the rotating rod 7, multiple sets of grooves 17 disposed outside the fixed block 16, and a rotating plate rotatably connected in the grooves 17. A pull block 20 is fixedly connected to the outside of the rotating plate, a first magnet 18 is fixedly connected inside the groove 17, and a second magnet 19 is fixedly connected to the position of the rotating plate corresponding to the outside of the fixed block 16. The first magnet 18 is attracted and fixed to the rotating plate, so that the rotating plate is stably installed in the mounting groove. The rotating plate is made of iron plate. When it is necessary to manually operate the raising and lowering of the gate 2, the pull block 20 is pulled to rotate and open the rotating plate from the groove 17 and attract and fix it to the second magnet 19. Then, the rotating plate is held by hand, and the rotating rod 7 is rotated, so that the worm gear 5 and worm 6 can be manually operated to complete the raising and lowering of the gate 2.

[0027] The operation process of this utility model is as follows:

[0028] When the gate 2 needs to be pulled up by electric drive, simply start the motor 11 to drive the second bevel gear 10 to rotate, the second bevel gear 10 to drive the first bevel gear 9 to rotate, thereby driving the rotating rod 7 to rotate, the rotating rod 7 to drive the worm gear 6 to rotate, and the worm gear 6 to drive the nut sleeve 4 to rotate. Thus, through the meshing of the nut sleeve 4 and the threaded rod 3, the threaded rod 3 can drive the gate 2 to move upward, thereby opening the gate 2. Control the motor 11 to rotate in the opposite direction, thereby allowing the gate 2 to slide downward.

[0029] In the event of a power outage, when it is necessary to manually operate the raising and lowering of the gate 2, simply pull the pull block 20 to rotate the rotating plate out of the groove 17 and fix it to the second magnet 19. Then rotate the threaded column 12 to make the nut block 13 drive the fixing ring 15 to move downward. The fixing ring 15 drives the motor 11 to move downward, thereby disengaging the second bevel gear 10 from the first bevel gear 9.

[0030] Subsequently, holding the rotating plate, the operating rotating rod 7 is rotated, so that the worm wheel 5 and the worm 6 can be manually operated to rotate, and the lifting of the gate plate 2 is completed;

[0031] In conclusion, the gate plate 2 can be lifted by power and manual operation.

[0032] The standard parts used in the utility model can be purchased from the market, the special-shaped parts can be ordered according to the description and the drawings, the specific connection mode of each part adopts the conventional means such as bolts, rivets and welding in the prior art, the machinery, parts and equipment adopt conventional models in the prior art, the circuit connection adopts the conventional connection mode in the prior art, and details are not described herein, and the contents not described in detail in the description belong to the prior art known to the person skilled in the art.
