Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a water flow regulating device used in water conservancy projects. Background Art

[0002] In order to regulate the irrigation volume, some irrigation water conservancy channels are often equipped with water flow regulating devices to control the water flow. Usually, valves are used to regulate the water flow. Since the irrigation water conservancy channel itself has a small flow rate, in order to save costs, the gate on the channel is usually a door panel, and water is released for irrigation by manually controlling the lifting of the door panel. However, since the door panel is normally in a water-blocking state, the water pressure always presses on the door panel, making it inconvenient to pull up the door panel manually, and the height of the door panel is easily changed due to the impact of the water flow.

[0016] A water flow regulating device for a hydraulic project comprises a frame 1 and a gate plate 2. Figure 1 The frame 1 has slide grooves 3 on both sides, the gate plate 2 is slidably arranged in the frame 1 through the slide grooves 3, an adjustment plate 4 is slidably arranged in the gate plate 2, and drainage holes 5 are evenly arranged on the gate plate 2;

[0017] The gate plate 2 slides in the frame 1 through the slide groove 3 to prevent the gate plate 2 from changing its position due to the impact of the water flow. The water flows through the drainage holes 5 on both sides of the gate plate 2 for drainage.

[0018] Figure 2-3 A symmetrical hydraulic telescopic rod 6 is fixedly arranged at the top of the frame 1, and the other end of the hydraulic telescopic rod 6 is fixedly connected to the top of the gate plate 2. A moving assembly 7 for driving the adjustment plate 4 to move is arranged at the top of the frame 1. The moving assembly 7 includes a symmetrical bearing seat 8 fixedly arranged at the top of the frame 1, and a bidirectional screw 9 is rotatably arranged between the two bearing seats 8. A servo motor 10 is fixedly arranged on one side of the bearing seat 8, and the output end of the servo motor 10 is connected to the bidirectional screw 9. A left screw block 11 is slidably arranged on one side of the top of the frame 1, and a right screw block 17 is slidably arranged on the other side of the top of the frame 1. The left screw block 11 and the right screw block 17 are slidably arranged on the other side of the top of the frame 1. The screw block 17 is threadedly connected with the bidirectional screw rod 9. A left sliding block 12 is slidably provided on one side of the top of the adjusting plate 4. A right sliding block 13 is slidably provided on the other side of the top of the adjusting plate 4. A symmetrical left driving rod 14 is hingedly provided on both sides of the left screw block 11. The other end of the left driving rod 14 is hingedly provided on both sides of the right sliding block 13. A symmetrical right driving rod 15 is hingedly provided on both sides of the right screw block 17. The other end of the right driving rod 15 is hingedly provided on both sides of the left sliding block 12. The left driving rod 14 and the right driving rod 15 are staggered. Adjustment holes 16 are evenly provided on the adjusting plate 4, and the adjustment holes 16 match the drainage holes 5.

[0019] The working principle of the utility model is as follows: first, when the size of the water flow needs to be adjusted, the servo motor 10 is started, and the output end of the servo motor 10 drives the bidirectional screw 9 to rotate on the bearing seat 8, and the bidirectional screw 9 drives the left screw block 11 and the right screw block 17 to move closer to or away from each other on the bidirectional screw 9, and then the left screw block 11 and the right screw block 17 drive the left driving rod 14 and the right driving rod 15 to move, and at the same time, the left driving rod 14 and the right driving rod 15 are hinged and rotated on the left screw block 11 and the right screw block 17 and the left sliding block 12 and the right sliding block 13, and the left When the driving rod 14 and the right driving rod 15 move, the left sliding block 12 and the right sliding block 13 are pushed to move on the top of the adjusting plate 4, driving the adjusting plate 4 to move up and down. When the adjusting plate 4 moves, the water flow is adjusted. When the adjusting hole 16 on the adjusting plate 4 completely coincides with the drain hole 5 on the valve, the drainage volume is the largest. When the adjusting plate 4 drives the adjusting hole 16 to not coincide with the drain hole 5, the drain hole 5 is completely blocked by the adjusting plate 4, thereby stopping drainage. The size of the water flow is controlled by the cooperation of the adjusting hole 16 and the drain hole 5.

[0020] When adjusting the height of the gate plate 2, the adjusting plate 4 is moved by the moving component 7 to adjust the height of the adjusting plate 4, and the gate plate 2 is moved by the hydraulic telescopic rod 6. The adjusting plate 4 and the gate plate 2 are adjusted twice separately to avoid excessive pressure of drawing water at one time, which makes the device inconvenient to pull up.

[0021] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
