[0022] like Figures 1 to 4 As shown, the dam tilting gate of this embodiment includes a gate stem 1, which is located between the gate base 6 and the gate top plate 8. Gate plates 2 are provided on both sides of the gate stem 1. An actuator 3 is provided at the top of the gate stem 1, which is located at the top of the gate top plate 8. A limiting mechanism 4 is provided at the bottom of the gate stem 1, which is located inside the gate base 6. An angle sensor 5 is provided on the gate stem 1 above the gate plate 2. Gate frames 7 are provided on both sides of the gate base 6 and the gate top plate 8, and the gate plates 2 are located inside the gate frames 7. The angle sensor 5 is connected to the actuator 3 and the limiting mechanism 4 through a control module to achieve self-locking fixation at both ends of the tilting gate. The tilting gate control is stable and reliable, realizing the control of the dam tilting gate. The setting of the angle sensor 5 on the gate stem 1 makes the control of the tilting gate precise.

[0023] Specifically, the actuator 3 includes a servo motor 31, a connecting shaft 32, a worm gear 33, and a worm 34. The top of the gate valve stem 1 is provided with a connecting shaft 32, which passes through a shaft hole and is connected to the worm gear 33 via the gate top plate 8. The worm gear 34 is meshed on one side of the worm gear 33. The top of the gate top plate 8 is provided with a servo motor 31 via a motor mount. The output end of the servo motor 31 is connected to one end of the worm 34 via a coupling. The servo motor 31 drives the worm 34 to rotate inside the actuator box 35 at the top of the gate top plate 8. The rotation of the worm 34 drives the worm gear 33 to rotate. The rotation of the worm gear 33 drives the gate valve stem 1 and the gate valve plate 2 to rotate inside the gate frame 7 via the connecting shaft 32.

[0024] Furthermore, the limiting mechanism 4 includes a limiting wheel 41, an electric telescopic rod 42, and a limiting plate 43. The limiting wheel 41 is provided inside the gate base 6 through a receiving groove. The limiting wheel 41 has several evenly distributed limiting teeth on its circumference. The electric telescopic rod 42 is provided on both sides of the limiting wheel 41. The limiting plate 43 is provided at one end of the electric telescopic rod 42 near the limiting wheel 41. The limiting plate 43 is set in an arc-shaped plate structure. The bottom of the gate valve stem 1 is connected to the limiting wheel 41. The electric telescopic rod 42 pushes the limiting plate 43 to abut against the limiting wheel 41. The limiting plate 43 limits and fixes the limiting wheel 41, that is, the lower end of the gate valve stem 1 is limited and fixed by the limiting mechanism 4.

[0025] Furthermore, the output of the angle sensor 5 is electrically connected to the input of the control module through the processing module, and the output of the control module is electrically connected to the input of the servo motor 31 and the electric telescopic rod 42. When the angle detected by the angle sensor 5 is consistent with the opening angle required by the gate, the angle sensor 5 transmits the signal to the control module, the control module controls the servo motor 31 to stop running, and the control module controls the electric telescopic rod 42 to reset.

[0026] Furthermore, a sealing seat 44 is provided inside the gate base 6 above the limit wheel 41. The sealing seat 44 is wrapped around the gate stem 1, and the gate stem 1 is installed on the gate base 6 with good sealing performance.

[0027] Furthermore, the gate valve plate 2 is composed of a valve plate body 21 and a wear-resistant valve plate 22. The valve plate body 21 is provided on both sides of the gate valve stem 1. The bottom and sides of the valve plate body 21 are provided with wear-resistant valve plates 22. The valve plate body 21 is made of stainless steel plate and has high structural strength. The wear-resistant valve plate 22 is made of tungsten carbide and has good wear resistance.

[0028] Furthermore, the top of the gate top plate 8 is provided with an execution box 35, and the servo motor 31, worm gear 33 and worm 34 are located inside the execution box 35. The execution box 35 protects the servo motor 31, worm gear 33 and worm 34.

[0029] The usage method of this embodiment is as follows: The gate opening angle is input at the gate control terminal, controlling the servo motor 31 and the electric telescopic rod 42 to operate. The electric telescopic rod 42 drives the limit plate 43 away from the limit wheel 41. According to the required gate opening angle, the servo motor 31 drives the worm gear 34 inside the actuator box 35 at the top of the gate top plate 8 to rotate. The rotation of the worm gear 34 drives the worm wheel 33 meshing with it to rotate. The rotation of the worm wheel 33 drives the gate valve stem 1 and the gate valve plate 2 to flip inside the gate frame 7 via the connecting shaft 32. The angle sensor 5 on the gate valve stem 1 detects the gate angle. When the angle sensor 5 detects an angle that matches the required gate opening angle... When the angles are consistent, the angle sensor 5 transmits a signal to the control module. The control module controls the servo motor 31 to stop running and controls the electric telescopic rod 42 to reset. The electric telescopic rod 42 pushes the limit plate 43 to abut against the limit wheel 41. The limit plate 43 limits and fixes the limit wheel 41, that is, the lower end of the gate valve rod 1 is limited and fixed by the limit mechanism 4, while the upper end of the gate valve rod 1 is limited and fixed by the self-locking characteristic of the worm gear 33 and worm 34 meshing. This realizes the self-locking fixation of the top and bottom ends of the tilting gate, making the tilting gate control stable and reliable, making the tilting gate control precise, reducing wear, and extending the service life of the tilting gate used in dams.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
