Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering facilities technology, and in particular to a high-strength hydraulic dam. Background Technology

[0002] A hydraulic dam is a modern dam that uses a hydraulic system to control the rotation of gates or water-retaining structures, combining the water storage and flood control functions of traditional dams with flexible adjustability. Compared to fixed dams, hydraulic dams can dynamically adjust their rotation angle according to hydrological conditions, making them suitable for various scenarios such as river management, irrigation, power generation, and ecological flow regulation. A bottom-shaft hydraulically driven steel dam is a common type of hydraulic dam. It employs a bottom-fixed shaft structure and uses a hydraulic system to drive the rotation of steel gates. Its core feature is that the bottom of the gate is fixed by a hinge shaft, and a hydraulic cylinder pushes the gate to rotate around the shaft, achieving water retention or flood discharge functions. However, while existing bottom-shaft hydraulic dams effectively support the steel dam body when rotated to a vertical angle, under significant water flow impact, prolonged high water pressure makes it difficult to maintain the stability of the dam's vertical interception state, and in severe cases, it can even cause hydraulic system failure. Therefore, a high-strength hydraulic dam is needed. Utility Model Content

[0003] The purpose of this invention is to provide a high-strength hydraulic dam to solve the technical problems mentioned in the background section.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a high-strength hydraulic dam, comprising a base, dam components, hydraulic drive components, and support components.

[0006] The base is fixedly constructed on the river channel by cement concrete, with a diversion channel in the middle and installation slots symmetrically arranged on both sides of the diversion channel.

[0007] The dam assembly includes a steel dam body disposed within the intercepting channel. The lower part of the steel dam body is rotatably mounted on the base via a bottom shaft, and the two ends of the bottom shaft extend into the interior of the corresponding mounting slots.

[0008] The hydraulic drive assembly includes two hydraulic cylinders respectively hinged to the end walls of the two mounting slots. The plane containing the axis of each hydraulic cylinder is perpendicular to the plane containing the axis of the bottom shaft. The telescopic ends of the two hydraulic cylinders are rotatably connected to both ends of the bottom shaft through a connecting frame.

[0009] The support assembly includes multiple parallel support rods, the upper end of each support rod is hinged to the upper back side of the main body of the steel dam, and the lower end of each support rod is hinged to the upper part of multiple sliding sleeves slidably disposed on the base.

[0010] Furthermore, a discharge port is provided in the middle of the main body of the steel dam, and two baffles are symmetrically slidably arranged on the back side of the discharge port. Two first mounting plates are symmetrically fixed in the middle of the back side of the main body of the steel dam. A bidirectional screw is rotatably arranged between the two first mounting plates. A hydraulic motor for driving the bidirectional screw to rotate is arranged on the outer side of one of the first mounting plates. The two ends of the bidirectional screw have opposite external threads and two screw sleeves are arranged oppositely to their corresponding ends. The two screw sleeves are fixedly connected to the two baffles on the side facing the main body of the steel dam.

[0011] Furthermore, two pairs of second mounting plates are symmetrically fixedly arranged on the back side of the main body of the steel dam along the bidirectional screw.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

During this process, multiple support rods gradually form an oblique support on the back side of the steel dam body. After the steel dam body is flipped, a stable triangular support structure is formed between the steel dam body, multiple support rods, and the base ground. This helps to ensure the structural strength of the steel dam body after flipping and maintain the stability of the vertical interception state. Attached Figure Description

[0023] like Figures 1-4 As shown, a high-strength hydraulic dam includes a base 1, a dam assembly, a hydraulic drive assembly, and a support assembly.

[0024] The base 1 is fixedly constructed on the river channel by cement concrete, with a diversion channel 1-1 in the middle and two installation slots 1-2 symmetrically arranged on both sides of the diversion channel 1-1.

[0025] The dam assembly includes a steel dam body 2 disposed inside the intercepting channel 1-1. The lower part of the steel dam body 2 is rotatably mounted on the base 1 via a bottom shaft 3. The two ends of the bottom shaft 3 extend into the interior of the corresponding mounting slots 1-2.

[0026] The hydraulic drive assembly includes two hydraulic cylinders 4 respectively hinged to the end walls of the two mounting slots 1-2. The plane containing the axis of each hydraulic cylinder 4 is perpendicular to the plane containing the axis of the bottom shaft 3. The telescopic ends of the two hydraulic cylinders 4 are rotatably connected to the two ends of the bottom shaft 3 through a connecting frame 5.

[0027] In this embodiment, each connecting frame 5 includes a connecting sleeve 5-1 fixedly sleeved on the portion of the bottom shaft 3 located within the mounting groove 1-2. Specifically, the inner circumferential wall of the connecting sleeve 5-1 is uniformly provided with multiple fitting bosses 5-2 along the circumferential direction. The bottom shaft 3 has multiple fitting grooves along the circumferential direction at corresponding portions of the connecting sleeve 5-1, which are adapted to each of the fitting bosses 5-2. The outer side of the connecting sleeve 5-1 is hinged to the telescopic end of the hydraulic cylinder 4 via a bent connecting arm 5-3. When the hydraulic cylinder 4 telescopically moves, the connecting frame 5 drives the bottom shaft 3 and the steel dam body 2 to rotate.

[0028] The support assembly includes multiple parallel support rods 6, the upper ends of which are hinged to the upper back side of the steel dam body 2. In this specification, the "back side" refers to the side of the steel dam body 2 that is away from the impact of the water flow. The lower ends of each support rod 6 are hinged to the upper parts of multiple sliding sleeves 7 that are slidably mounted on the base 1.

[0029] In this example, two connecting plates 8 are symmetrically fixedly arranged on the base 1, and multiple horizontal sliding rods 9 are fixedly arranged at even intervals between the two connecting plates 8. Each sliding sleeve 7 is slidably installed on each sliding rod 9.

[0030] In practical application, the steel dam body is flipped to a vertical position by the driving action of the hydraulic cylinder and connecting frame. During this process, multiple support rods gradually form an oblique support on the back side of the steel dam body. After the steel dam body is flipped, the workers can fix it with bolts between the sliding sleeve and the corresponding sliding rod, thereby forming a stable triangular support structure between the steel dam body, multiple support rods and the base ground. This helps to ensure the structural strength of the steel dam body after flipping and maintain the stability of the vertical interception state.

[0031] As a further improvement to this utility model, a discharge port 2-1 is provided in the middle of the steel dam body 2, and two baffles 10 are symmetrically slidably installed on the back side of the discharge port 2-1. Specifically, two first mounting plates 11 are symmetrically fixedly arranged in the middle of the back side of the steel dam body 2, and a bidirectional screw 12 is rotatably installed between the two first mounting plates 11. A hydraulic motor 13 for driving the bidirectional screw 12 to rotate is provided on the outer side of one of the first mounting plates. The two ends of the bidirectional screw 12 have opposite external threads and two screw sleeves 14 are respectively threaded to their corresponding ends. The two screw sleeves 14 are fixedly connected to the two baffles 10 on the side facing the steel dam body 2. In this embodiment, the bidirectional screw is covered with a retractable corrugated protective sleeve at the positions between the corresponding first mounting plates 11 and the screw sleeves 14, and at the positions between the two screw sleeves 14, to avoid damage to the bidirectional screw transmission function due to factors such as mud and sand erosion.

[0032] With the above setup, when partial discharge of the river channel is required, the hydraulic motor can drive the bidirectional screw to rotate. Under the drive of the two screw sleeves, the two baffles move in opposite directions, thus no longer blocking the discharge outlet. The discharge outlet can meet the partial discharge demand, thereby eliminating the need to drive the entire steel dam to operate, effectively reducing energy consumption.

[0033] In addition, two pairs of second mounting plates 15 are symmetrically fixed along the bidirectional screw 12 on the back side of the steel dam body 2. A guide rod 16 is fixedly installed between the two second mounting plates 15 at the same height. Guide sleeves 17 that slide in cooperation with the guide rods 16 at the corresponding ends are fixedly installed at the upper and lower ends of the two baffles 10. The sliding cooperation between each guide sleeve 17 and the corresponding guide rod 16 ensures the stability of the linear movement of the two baffles 10.

[0034] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
