Description

Technical Field

[0001] This utility model relates to the field of hydraulic dam technology, specifically a novel composite hydraulic dam. Background Technology

[0002] Hydraulic dams are movable dams controlled by hydraulic technology in water conservancy projects. They consist of an arc-shaped dam face, hydraulic rods, support rods, and other components. Lifting and lowering are achieved through the direct thrust of hydraulic cylinders, serving both water-blocking and flood-discharging functions. As a typical example of movable dams, they, along with water conservancy landscape movable dams, hydraulic lifting dams, and hinged movable dams, form a large-span dam system, possessing a span advantage unmatched by conventional sluice gates. During the raising and water-blocking process of traditional hydraulic dams, the design of the cylinders and support rods in some hydraulic dams makes it difficult to precisely control the rising movement of the dam surface. This can easily lead to problems such as unstable rising and uneven speed, affecting the overall reliability of the dam surface operation. Furthermore, when the dam surface reaches its highest point, traditional hydraulic dams cannot effectively maintain the optimal state of the dam surface. Under prolonged operation or when subjected to the pushing force of water from the front, the dam surface may automatically descend, making it impossible to form a stable, year-round water storage state. This seriously affects the normal functioning of projects that require continuous water storage. Utility Model Content

[0003] To achieve the above objectives, this utility model is implemented through the following technical solution: a novel composite hydraulic dam, including a foundation, a first support is provided on the lower side of the foundation, a second support is provided on the upper side of the foundation, a connecting surface is provided on the lower side of both the first support and the second support, the connecting surface is connected to the foundation by a first anchor bolt and a second anchor bolt respectively, and a dam surface is rotatably connected to the upper side of the second support; A lower support rod is rotatably connected to one side of the upper part of the first support, and a telescopic cylinder is rotatably connected to the other side of the first support. An upper support rod is rotatably connected to the upper part of the lower support rod, and the upper part of the upper support rod is rotatably connected to one side of the dam surface. The telescopic end of the telescopic cylinder is rotatably connected to the upper part of the lower support rod.

[0004] In the above scheme: the upper side of the dam surface is inclined.

[0005] In the above scheme, both the first anchor bolt and the second anchor bolt are L-shaped anchor bolts.

[0006] In the above scheme: an oil pipe trench is provided on one side of the foundation.

[0007] This utility model provides a novel composite hydraulic dam with the following advantages: Through a unique structural design, it effectively solves the problem of unstable operation in traditional hydraulic dams. The first and second supports are firmly connected to the foundation via first and second anchor bolts, respectively, providing a solid foundation for the entire dam body. During the water-retaining process, the telescopic cylinder rotates in coordination with the lower and upper support rods. After high-pressure hydraulic oil is injected into the rodless chamber of the cylinder, it smoothly pushes the lower support rod upward, thereby driving the upper support rod and the dam surface to rise. This avoids the unstable and uneven rising speed of traditional hydraulic dams. The problem is that when the dam surface reaches its highest point, the hydraulic cylinder will apply an additional 1 to 2 centimeters of pressure, causing the center of the upper and lower support rods to move backward towards the dam surface. The support rods are in an arc shape. At this time, the water in front of the dam pushes the dam surface backward, and the force of the dam surface pushes the support rods backward. Meanwhile, the hydraulic cylinder is already at its longest extension, pulling the upper and lower supports forward, maintaining the optimal state of the dam surface. Under this state, no matter how long it operates, the dam surface will not automatically drop, thus forming a stable water storage state year-round. This meets the functional requirements of projects that need continuous water storage and improves the reliability and stability of the project. Attached Figure Description

[0011] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0012] Example Please see Figure 1-2 A new type of composite hydraulic dam includes a foundation 1, a first support 2 is provided on the lower side of the foundation 1, a second support 3 is provided on the upper side of the foundation 1, and a connecting surface is provided on the lower side of both the first support 2 and the second support 3. The connecting surfaces are connected to the foundation 1 by the first anchor bolt 4 and the second anchor bolt 5 respectively. A dam surface 6 is rotatably connected to the upper side of the second support 3. The lower support rod 7 is rotatably connected to one side of the upper side of the first support 2, and the telescopic cylinder 8 is rotatably connected to the other side of the first support 2. The upper support rod 9 is rotatably connected to the upper side of the lower support rod 7. The upper side of the upper support rod 9 is rotatably connected to one side of the dam surface 6. The telescopic end of the telescopic cylinder 8 is rotatably connected to the upper side of the lower support rod 7. It should be noted that during the operation of the hydraulic dam, high-pressure hydraulic oil is injected into the rodless chamber of the telescopic cylinder 8, and the telescopic cylinder 8 begins to slowly extend. The telescopic cylinder 8 pushes the lower support rod 7 to rise. At this time, the lower support rod 7 is at a 175-degree angle to the inside. When the telescopic cylinder 8 extends, the lower support rod 7 also rises. When the lower support rod 7 rises, it will move the upper support rod 9 upward. At this time, the upper support rod 9 moves the center of the two support rods backward because the lower support rod 7 moves backward when it rises from the 175-degree position, instead of moving towards the dam face 6. However, the upper support rod 9 cannot move towards the dam face 6 due to radius and angle issues, but will move in the opposite direction. Therefore, the dam face 6 will continue to move upward. When the dam surface 6 reaches its highest point, the telescopic cylinder 8 will be loaded by 1 to 2 centimeters, causing the center of the upper and lower support rods 7 to move backwards from the dam surface 6. At this time, the upper support rod 9 and the lower support rod 7 are in an arc shape. When the water in front of the dam surface 6 pushes the dam surface 6 backwards, the force of the dam surface 6 pushes the support rods backwards. Since the upper support rod 9 and the lower support rod 7 are in an arc shape, the center of the upper support rod 9 and the lower support rod 7 are also under force and moving backwards. At this time, the telescopic cylinder 8 has reached its longest position and will pull the upper and lower supports forwards. Because the telescopic cylinder 8 has reached its longest position, it will always maintain the optimal state of the dam surface 6. In this state, no matter how long it runs, the dam surface 6 will not automatically descend, thus forming year-round water storage. When a sudden surge of water occurs while the dam face 6 is operating at its highest water level, the motor is activated to lower the dam. The oil in the rod chamber of the telescopic cylinder 8 pulls back the upper support rod 9 and lower support rod 7, causing them to drop 175 degrees inward. The motor can then be turned off, and the dam gate returns to its flood discharge point entirely under water pressure. The upper side of the dam surface 6 is inclined to increase the overall area of ​​the dam surface 6 and improve its overall performance. The first anchor bolt 4 and the second anchor bolt 5 are both L-shaped anchor bolts to ensure the stability of the first support 2 and the second support 3. An oil pipe trench 10 is set on one side of the foundation 1 to provide reasonable space for the layout of the oil pipes, making the oil pipes more neat and standardized, avoiding the safety hazards that may be caused by the messy layout of the oil pipes, and also facilitating the maintenance and repair of the oil pipes.
