Technical Field

[0001] The utility model belongs to the technical field of water inlet gates, and in particular relates to a water inlet gate limit control device. Background Art

[0002] Inlet gates are key equipment in water conservancy projects, water supply and drainage systems, and other fields. They control water inflow and are typically composed of a gate body, door frame, sealing device, and opening and closing mechanism. The gate body is often made of metal, providing sufficient strength and rigidity to withstand water pressure. Its functions include regulating flow, controlling water levels, and blocking debris, making it crucial for ensuring the safe operation of water conservancy facilities and meeting specific process requirements. Opening and closing methods include manual, electric, and hydraulic, depending on the specific situation. Advanced intake gates can be equipped with automated control systems for remote operation and precise control.

[0003] The problem with the existing technology is that there is generally no limit control structure installed on the surface of the water inlet gate, which makes it difficult to control the opening degree of the gate, resulting in the situation where the water inflow is difficult to control when the gate is opened. Therefore, we propose a water inlet gate limit control device. Utility Model Content

[0024] The above scheme is adopted: through the design of the shell 1, baffle 2, lifting assembly 3, limit assembly 4 and connecting plate 5, when in use, the limit assembly 4 can be set in advance to limit the movable height of the baffle 2, and then the lifting assembly 3 is started to drive the baffle 2 to move upward. When it moves to the specified position, the limit assembly 4 will limit the baffle 2 from continuing to move upward, thereby achieving the effect of facilitating the control of the movable height of the baffle 2 and thus controlling the water flow.

[0025] refer to Figure 2The lifting assembly 3 includes a movable wheel 302, which is fixedly connected to one side of the upper surface of the connecting plate 5. The surface of the movable wheel 302 is movably connected to a movable shell 303, and the upper surface of the movable shell 303 is fixedly connected to a first gear 304; the first gear 304 is internally threaded with a screw rod 301, and the screw rod 301 is fixedly connected to one side of the upper surface of the baffle 2. The middle part of the upper surface of the connecting plate 5 is fixedly connected to a motor 305, and the output end of the motor 305 is fixedly connected to a second gear 306.

[0026] The above solution is adopted: through the design of the screw rod 301, movable wheel 302, movable shell 303, first gear 304, motor 305 and second gear 306, when the motor 305 is running, the second gear 306 will be used to drive the first gear 304 and the movable shell 303 to rotate on the surface of the movable wheel 302. Since the shell 1 limits the movement of the baffle 2, the screw rod 301 will drive the baffle 2 to move upward, thereby achieving the effect of facilitating the opening of the gate.

[0027] refer to Figure 2 、 Figure 3 and Figure 4 The limiting assembly 4 includes a second rotating shaft 412, which is fixedly connected to the other side of the upper surface of the connecting plate 5. One side of the surface of the second rotating shaft 412 is fixedly connected to the first transmission wheel 408, and one side of the inner wall of the first transmission wheel 408 is fixedly connected to the second mounting plate 413; one side of the surface of the second gear 306 is fixedly connected to the second transmission wheel 409, and the second transmission wheel 409 and the first transmission wheel 408 are both connected to each other by a transmission belt 410, and the other side of the lower surface of the connecting plate 5 is fixedly connected to a stop shell 407; a rotating rod 403 is commonly provided in the first transmission wheel 408 and the baffle shell 407, one side of the surface of the rotating rod 403 is fixedly connected to the first mounting plate 411, and the first rotating shaft 401 is commonly fixedly connected between the rotating rod 403 and the baffle 2; one end of the surface of the rotating rod 403 is threadedly connected to a threaded block 402, and both sides of the inside of the threaded block 402 are fixedly connected to rotating columns 405, and the surfaces of the two groups of rotating columns 405 are both sleeved with torsion springs 404, and one side of the two groups of torsion springs 404 is fixedly connected to a movable plate 406.

[0028] The above solution is adopted: through the design of the first rotating shaft 401, the threaded block 402, the rotating rod 403, the torsion spring 404, the rotating column 405, the movable plate 406, the blocking shell 407, the first transmission wheel 408, the second transmission wheel 409, the transmission belt 410, the first mounting plate 411, the second rotating shaft 412 and the second mounting plate 413, when in use, since one end of the rotating rod 403 is provided with a thread, the rotating threaded block 402 can be rotated to control the position of the threaded block 402, and when the motor 305 drives the second gear 306 to rotate, it will also drive the second transmission wheel 409 to rotate, so that the second transmission wheel 409 is driven by the transmission belt 410. 10 drives the first transmission wheel 408 to rotate on the surface of the second rotating shaft 412, and the first transmission wheel 408 will use the second mounting plate 413 to drive the rotating rod 403 on the surface of the first mounting plate 411 to rotate on the surface of the first rotating shaft 401, and due to the action of centrifugal force, the movable plate 406 will be swung outward and unfolded, and the torsion spring 404 is used to drive the movable plate 406 to reset when the swinging stops.

[0029] The working principle of this utility model:

[0030] When in use, when the motor 305 is running, the second gear 306 will be used to drive the first gear 304 and the movable shell 303 to rotate on the surface of the movable wheel 302. Since the shell 1 limits the movement of the baffle 2, the screw rod 301 will drive the baffle 2 to move up, which is convenient for opening the gate. Since one end of the rotating rod 403 is provided with a thread, the position of the thread block 402 can be controlled by rotating the thread block 402. When the motor 305 drives the second gear 306 to rotate, it will drive the second transmission wheel 409 to rotate, so that the second transmission wheel 409 drives the transmission belt 410 to drive The first transmission wheel 408 rotates on the surface of the second rotating shaft 412, and the first transmission wheel 408 will use the second mounting plate 413 to drive the rotating rod 403 on the surface of the first mounting plate 411 to rotate on the surface of the first rotating shaft 401, and due to the action of centrifugal force, the movable plate 406 will be swung outward and unfolded. The torsion spring 404 is used to drive the movable plate 406 to reset when the swinging stops. When the lead screw 301 drives the baffle 2 to move up to the specified position, the movable plate 406 will be blocked by the baffle shell 407, and finally the motor 305 will stop running and stop moving the baffle 2 upward, so as to facilitate the control of the opening height of the gate.
