Referring to fig. 1 and 2, in a first embodiment of the present application, an automatic leveling device for a butterfly valve of a water inlet pipe of a water turbine is provided, which includes a flow control unit 100, wherein the flow control unit 100 includes a pipe 101, a hydraulic control mechanism 102 disposed on a side surface of the pipe 101, a driven structure 103 disposed at one end of the hydraulic control mechanism 102, a first butterfly valve 104 disposed at the bottom of the driven structure 103, and a second butterfly valve 105;
in the flow control unit 100, the hydraulic control mechanism 102 includes one hydraulic cylinder, one control valve, and one oil pump. The hydraulic control mechanism 102 can be used for controlling the opening degree of the first butterfly valve 104 and the second butterfly valve 105, so as to realize the flow control of the liquid in the pipeline 101. The control valve of the hydraulic control mechanism 102 may adjust the oil pump output pressure by receiving a signal, thereby controlling the opening degrees of the first butterfly valve 104 and the second butterfly valve 105. The driven structure 103 is connected with the hydraulic control mechanism 102, so that control signals from the hydraulic control mechanism 102 can be received, and the opening degrees of the first butterfly valve 104 and the second butterfly valve 105 are correspondingly adjusted, so that the flow control of the fluid in the pipeline 101 is realized. In addition, a flowmeter is provided below the first butterfly valve 104 and the second butterfly valve 105 at the bottom of the driven structure 103 for measuring the flow rate of the liquid in the pipe 101, thereby more accurately performing flow rate control.
Further, the hydraulic control mechanism 102 includes a frame 102a, a hydraulic rod 102b provided on an inner wall of the frame 102a, and a telescopic rod 102c provided in the hydraulic rod 102b, and in the hydraulic control mechanism 102, the hydraulic rod 102b is responsible for generating hydraulic pressure in a hydraulic cylinder to adjust the opening degrees of the first butterfly valve 104 and the second butterfly valve 105. In order to make the hydraulic rod 102b generate a larger thrust under the same hydraulic pressure, a telescopic rod 102c can be arranged on the inner side of the hydraulic rod 102b, and the telescopic rod 102c can be telescopic under the pushing of the hydraulic rod 102b, so that the thrust is correspondingly increased. Specifically, the telescoping rod 102c may be coupled to the hydraulic rod 102b by an adjustable screw collar, and rotation of the screw collar may cause minor adjustments in the length of the telescoping rod 102 c. This design can effectively improve the response speed and control accuracy of the hydraulic control mechanism 102. Meanwhile, the frame 102a is provided at the inner wall of the hydraulic rod 102b, so that the rigidity and stability of the hydraulic rod 102b can be increased, thereby improving the stability and reliability of the entire flow control unit 100.

When the hydraulic control mechanism 102 receives an instruction from a control signal, the hydraulic rod and the telescopic rod push the first butterfly valve 104 and the second butterfly valve 105 on the driven structure 103 to be correspondingly opened or closed, so that the control of the liquid flow in the pipeline 101 is realized. Through the clamping of the clamping block 103a and the clamping groove 102a-1, the connection between the hydraulic control mechanism 102 and the driven structure 103 can be firmer, and the normal operation of the flow control unit 100 is ensured. When the components are required to be repaired or replaced, the clamping structure between the clamping block 103a and the clamping groove 102a-1 can be disassembled, so that later maintenance is facilitated.
Further, a baffle ring 104a is disposed on the first butterfly valve 104, a first baffle column 104b is disposed on the baffle ring 104a, a rotating column 104c and a first half-disc 104d disposed on the rotating column 104c are further disposed on the first butterfly valve 104, a baffle ring 104a may be disposed on the first butterfly valve 104, and a first baffle column 104b is disposed on the baffle ring 104a to help control the rotation angle of the first butterfly valve.

In addition, a second semicircular piece 105c may be provided on the side surface of the pipe groove 105a, and the shape of the second semicircular piece corresponds to the shape of the inner hole of the second butterfly valve. At this time, the opening degree of the second butterfly valve 105 in the pipe 101 is controlled to be rotated to a specific angle by controlling the output pressure of the hydraulic control mechanism 102 and the thrust force of the hydraulic lever.

When the hydraulic force output from the hydraulic control mechanism 102 pushes the hydraulic lever and the telescopic lever, the first butterfly valve 104 will rotate until the first stopper 104b abuts against the first groove 103b-1, thereby completing the control of the first butterfly valve 104. This design may ensure stability and reliability of the first butterfly valve 104 while also improving control accuracy and operating efficiency of the flow control unit 100.

Further, a rotation post 104c may be concentrically disposed within the tube slot 105a to help control the rotational axis of the second butterfly valve. When the hydraulic force output from the hydraulic control mechanism 102 pushes the hydraulic lever and the telescopic lever, the second butterfly valve 105 will rotate until the second stopper 105b abuts against the second groove 103b-2, thereby completing the control of the second butterfly valve 105. This design ensures the stability and reliability of the second butterfly valve 105 while also improving the control accuracy and operating efficiency of the flow control unit 100.
