Description

Technical Field

[0001] The utility model relates to the technical field of valve switches, in particular to a valve switch control fixture. Background Art

[0002] Valve control technology plays a vital role in many industrial and automation systems. It is used to control the flow of fluids (liquids or gases). Common applications include water treatment, petrochemicals, manufacturing, and heating, ventilation, and air conditioning (HVAC) systems.

[0003] The existing method for closing valves in hydropower stations is not only time-consuming and labor-intensive, requiring personnel to travel to the valve location, but also has low precision. Since the accuracy of valve closing cannot be guaranteed every time, the valve may not be closed tightly, causing accidents.

[0004] With the continuous development of hydropower plant automation technology, the requirements for precision and reliability in valve opening and closing control are increasing. Traditional manual operation methods can no longer meet the efficient, accurate, and remote control requirements of modern hydropower plants. Therefore, the development of a fixture that can automatically and precisely control the opening and closing of hydropower plant valves is of great significance. Utility Model Content

[0005] The purpose of the utility model is to provide a valve switch control fixture to solve the technical problems in the background art that manually closing a valve is time-consuming and labor-intensive and the valve closing control accuracy is low.

[0006] To achieve the above-mentioned purpose, the technical solution of the present utility model provides a valve switch control fixture, which includes a supporting mechanism, a clamping mechanism and a rotating mechanism, wherein:

[0007] The supporting mechanism includes an equipment fixing part, on which a first driving motor is installed. The supporting mechanism is rotatably connected to the rotating mechanism through the first driving motor, and the rotation axis of the rotating mechanism is perpendicular to the supporting mechanism; at least one clamping mechanism is retractably installed on the rotating mechanism, and the clamping mechanism is used to control the valve switch.

[0008] Furthermore, the valve switch control fixture also includes a remote control device, which is fixedly installed on a side of the equipment fixing part away from the rotating mechanism.

[0009] Furthermore, the rotating mechanism includes a rotating shaft and a turntable, the output shaft of the first drive motor is connected to one end of the rotating shaft through a coupling, the other end of the rotating shaft is fixedly connected to the turntable, and the extension surface of the turntable is perpendicular to the axial direction of the rotating shaft.

[0010] Furthermore, at least one mounting hole is provided on the turntable on a side away from the rotating shaft, an electric telescopic rod is installed in the mounting hole, and the clamping mechanism is fixedly connected to the turntable via the electric telescopic rod.

[0011] Furthermore, the clamping mechanism includes a rotator, a second drive motor, a bidirectional screw and a clamping piece.

[0023] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] It should be noted that similar numbers and letters represent similar items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] See Figures 1 to 3 As shown, at least one embodiment of the present disclosure provides a valve switch control fixture, including a supporting mechanism, a clamping mechanism and a rotating mechanism, wherein: the supporting mechanism includes a device fixing part 1, a first drive motor 2 is installed on the device fixing part 1, the supporting mechanism is rotatably connected to the rotating mechanism through the first drive motor 2, and the rotation axis of the rotating mechanism is perpendicular to the supporting mechanism; at least one clamping mechanism is retractably installed on the rotating mechanism, and the clamping mechanism is used to control the valve switch.

[0026] Specifically, in this embodiment, there are two clamping mechanisms, and a remote control device 3 is provided on the outside of the equipment fixing part 1. The outside of the equipment fixing part 1 of the rotating clamping device is fixedly connected to the first drive motor 2, and the output shaft of the first drive motor 2 is connected to the rotating shaft 6 through a coupling. One end of the rotating shaft 6 is fixedly connected to the turntable 7, and two mounting holes 5 are provided on one side of the turntable 7. Electric telescopic rods 8 are installed inside the two mounting holes 5. One end of the two electric telescopic rods 8 is fixedly connected to a rotator 11, and one side of the rotator 11 is fixedly connected to a second drive motor 10. The output shaft of the second drive motor 10 is connected to a bidirectional screw rod 12 through a coupling. The outer wall of the bidirectional screw rod 12 is movably connected to two clamping members 9, and the opposite sides of the two clamping members 9 are provided with anti-slip grooves.

[0027] Specifically, in this embodiment, after the rotary clamping device is added, when it is necessary to close or open the valve, the valve opening and closing time, action sequence and other parameters are set through the remote control system, and the settings are saved. The remote control system sends a command to the remote control device to cause the rotary clamping device to start to act according to the set parameters, and drives the clamping mechanism to complete the valve opening and closing operation. After receiving the command, the remote control device 3 first starts the electric telescopic rod 6 to send the rotator to a suitable position, and then starts the second drive motor 10. Under the action of the bidirectional screw rod 12, the two clamping members 9 are moved toward the middle to firmly clamp the edge of the turntable. The anti-slip groove on the clamping part 9 can effectively prevent the clamping part 9 from not clamping tightly. Then the first drive motor 2 is started to drive the two clamping parts 9 to start rotating at high speed, and the turntable starts to rotate to close or open the valve. During operation, the control system monitors the operating status and valve position of the clamp in real time through the display or touch screen. If necessary, the parameters can be adjusted. When the valve is fully opened or closed, the clamp will automatically stop and return to the standby state. Through advanced mechanical transmission and electrical control technology, the switching operation of the hydropower station valve is realized, with the characteristics of high precision, high reliability and high safety.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
