[0022] See also Figure 1-5As shown, a lifting device for a water conservancy gate plate includes a support frame 1, which can support the device so that the device can work. The inner cavity of the support frame 1 is slidably connected to a water baffle 2, which can block and control the water source. The top of the support frame 1 is bolted with a stepper motor 3, and a moving component 4 is provided on one side of the stepper motor 3. The moving component 4 consists of a screw rod and a sleeve. Under the action of the stepper motor 3 rotating the sleeve, the screw rod can drive the water baffle 2 to move in the inner cavity of the support frame 1, allowing the staff to control the water baffle 2 to block and release the water source. The output shaft of the stepper motor 3 is connected to a tapered shaft through two belt pulleys and a timing belt drive. Gear set 5, the bevel gear set 5 is composed of two bevel gears meshing with each other, and a reciprocating mechanism 6 is provided on the other side of the bevel gear set 5. Under the action of the stepping motor 3 and the bevel gear set 5, the reciprocating mechanism 6 can work. The surface of the support frame 1 is bolted with a fixed shell 7. Under the action of the fixed shell 7, the reciprocating mechanism 6 can work more stably. The surface of the support frame 1 is rotatably connected with a rotating rod 8. The surface of the rotating rod 8 is fixedly connected to the inner cavity of the bevel gear set 5. Under the action of the rotating rod 8, the bevel gear set 5 can be made more stable when working, thereby increasing the stability of the device. A moving rod 9 is provided on one side of the fixed shell 7. Between the bevel gear set 5 and the reciprocating mechanism 6, a rotating rod 8 is provided. With the cooperation of the complex mechanism 6, the moving rod 9 can be reciprocated on one side of the fixed shell 7. The top of the support frame 1 is bolted with a fixed sleeve 10, and the inner cavity of the fixed sleeve 10 is slidably connected to the surface of the moving rod 9. Under the action of the fixed sleeve 10, the position deviation of the moving rod 9 during operation is effectively prevented, which increases the stability of the moving rod 9 and thus increases the stability of the device. The top of the support frame 1 is bolted with a liquid storage shell 13, and the top of the liquid storage shell 13 is bolted with a mounting shell 11. The surface of the moving rod 9 is slidably connected to the inner cavity of the mounting shell 11. The inner cavity of the mounting shell 11 is provided with a conveying mechanism 12, and the top of the liquid storage shell 13 is connected with a connecting pipe 14. The connecting pipe 1 4 is communicated with the surface of the mounting shell 11. Under the action of the moving rod 9 and the conveying mechanism 12, the lubricating liquid inside the liquid storage shell 13 can enter the interior of the mounting shell 11 through the connecting pipe 14. The other side of the mounting shell 11 is connected with a conveying pipe 15. The conveying pipe 15 can transport the lubricating liquid inside the mounting shell 11. The other end of the conveying pipe 15 is connected with a nozzle 16. The nozzle 16 can allow the lubricating liquid inside the conveying pipe 15 to lubricate the screw rod of the moving component 4, which is convenient for the staff to maintain and repair the screw rod of the moving component 4, reduces the workload of the staff, and increases the safety of the staff, thereby improving the use effect of the device.

[0023] The reciprocating mechanism 6 includes a turntable 61, one side of the turntable 61 is fixedly connected to one end of the rotating rod 8, and the other side of the turntable 61 is hinged with a connecting rod 62, and the other end of the connecting rod 62 is hinged with a moving block 63. The surface of the moving block 63 is slidably connected to the inner cavity of the fixed shell 7, and the other side of the moving block 63 is bolted to one end of the moving rod 9. The cross-sectional shape of the moving block 63 is I-shaped and has the same shape as the inner cavity of the fixed shell 7. Under the cooperation of the stepping motor 3 and the bevel gear set 5, the rotating rod 8 can drive the turntable 61 to rotate, and the turntable 61 can make the moving block 63 reciprocate in the inner cavity of the fixed shell 7 through the connecting rod 62, so that the moving block 63 drives the moving rod 9 to reciprocate in the inner cavity of the mounting shell 11, and under the cooperation of the conveying mechanism 12, the lubricating liquid inside the liquid storage shell 13 can lubricate the screw rod of the moving component 4 through the nozzle 16, which is convenient for the staff to maintain and repair the screw rod of the moving component 4, reduces the workload of the staff, and improves the safety of the staff.

[0024] The conveying mechanism 12 includes a piston 121, one side of the piston 121 is bolted to one side of the moving rod 9, the surface of the piston 121 is slidably connected to the inner cavity of the mounting shell 11, the surface of the inner cavity of the mounting shell 11 is hinged with a first one-way door 122, and the surface of the mounting shell 11 is hinged with a second one-way door 123. The second one-way door 123 is located in the center of the conveying pipe 15. When the moving rod 9 drives the piston 121 away from the first one-way door 122, the air volume inside the mounting shell 11 increases and the pressure decreases, allowing the lubricating fluid inside the liquid storage shell 13 to open the first one-way door 122 through the connecting pipe 14 and enter the interior of the mounting shell 11. When the moving rod 9 drives the piston 121 to approach the second one-way door 123, the air volume inside the mounting shell 11 decreases and the pressure increases, allowing the lubricating fluid inside the mounting shell 11 to open the second one-way door 123 and enter the interior of the conveying pipe 15, so that the lubricating fluid inside the liquid storage shell 13 can maintain and repair the screw of the moving component 4 through the nozzle 16, thereby increasing the use effect of the device.

[0025] Working principle: When the staff cooperates with the stepper motor 3 and the moving assembly 4, the water baffle 2 can be moved in the inner cavity of the support frame 1. At the same time, the stepper motor 3 drives the bevel gear set 5 to rotate the rotating rod 8 through two belt pulleys and a timing belt. The rotating rod 8 drives the turntable 61 to rotate. The turntable 61 drives the moving block 63 to reciprocate in the inner cavity of the fixed shell 7 through the connecting rod 62. The moving block 63 drives the moving rod 9 to reciprocate in the inner cavity of the mounting shell 11. When the moving rod 9 causes the piston 121 to move away from the first one-way door 122, the piston 121 moves back and forth. During movement, the air volume inside the mounting shell 11 increases and the pressure decreases, causing the lubricating fluid inside the liquid storage shell 13 to enter the interior of the mounting shell 11 through the connecting pipe 14 to open the first one-way door 122. When the moving rod 9 drives the piston 121 to move in the direction of the first one-way door 122, the air volume inside the mounting shell 11 decreases and the pressure increases, causing the lubricating fluid inside the mounting shell 11 to open the second one-way door 123 and enter the interior of the delivery pipe 15. Subsequently, the lubricating fluid is allowed to maintain and service the screw rod of the moving component 4 through the nozzle 16, and then the staff can close the device.
