Description

Technical Field

[0001] This utility model belongs to the field of steel dam technology, and in particular relates to a steel dam driven by a bottom shaft. Background Technology

[0002] A dam is a control facility used to close and open a water discharge channel. It is an important component of water conservancy projects, used to intercept water flow, control water levels, and regulate flow. Dams are typically installed in rivers to block water flow. Modern dams generally consist of multiple steel plates, each connected to a hydraulic rod mechanism. When water is released into the river, the steel plates are tilted, and the hydraulic rod mechanism is submerged in water for an extended period. This severely accelerates corrosion of the hydraulic rod mechanism, affecting the opening and closing process of the steel plates and ultimately rendering the dam unusable. Utility Model Content

[0003] To address the above problems, this utility model provides a steel dam driven by a bottom shaft.

[0004] This utility model is implemented as follows: A steel dam driven by a bottom shaft includes a cylindrical bottom shaft. Multiple hinge seats are uniformly fixed on a concrete surface below the bottom shaft. A semi-circular groove is formed at the center of the upper end of each hinge seat. The diameter of the groove is the same as the diameter of the bottom shaft. The bottom shaft corresponds to the groove and is positioned within it. The multiple hinge seats reliably support the bottom shaft, allowing it to rotate smoothly within the groove. The bottom shaft is fixedly connected to one end of the steel dam, forming an integral structure. The bottom shaft drives the steel dam to rotate. Concrete piles are installed at both ends of the steel dam, and a cavity is formed in the center of each concrete pile. A base is fixedly installed on one side of the cavity to increase the height of the hydraulic rod mechanism. A base is fixedly installed at the upper end of the base. Frame plates are vertically and symmetrically fixed on both sides of the upper end of the base. The hydraulic rod mechanism is arranged between the frame plates. A block is fixedly installed on the outer wall of the hydraulic rod mechanism located between the frame plates. A shaft is horizontally and symmetrically fixed at the middle position of both ends of the block. A shaft hole is opened at the middle position of the frame plate. The end of the shaft passes through the center of the bearing in the shaft hole and is fixedly connected to the bearing. This ensures that the hydraulic rod mechanism and the base can be reliably connected, guaranteeing the stability of the hydraulic rod mechanism's position, and also allows the hydraulic rod mechanism to rotate within a certain angle along the shaft.

[0005] The end of the bottom shaft passes tightly through the through hole in the concrete pile and is located in the cavity. A crank arm is provided in the cavity. One end of the crank arm has a sleeve hole. One end of the bottom shaft passes through the sleeve hole and is fixedly connected to the crank arm. The other end of the crank arm is hinged to the end of the hydraulic rod mechanism. The hydraulic rod mechanism drives the crank arm to move, which in turn drives the bottom shaft to rotate. When the hydraulic rod mechanism is in its shortest state, the steel dam is in a vertical state; when the hydraulic rod mechanism is in its longest state, the steel plate is in a horizontal state.

[0006] Preferably, an arc-shaped groove is provided on the side wall of the concrete pile near the steel dam. The groove corresponds to the position of the steel dam, and the end of the steel dam is located in the groove. The groove limits the position of the end of the steel dam, and the end of the steel dam is in reliable contact with the groove to prevent water seepage.

[0007] Preferably, a waterproof sleeve is tightly fitted and fixed to the concrete pile within the through hole on the concrete pile to prevent water from entering the cavity. A frameless oil seal and an O-ring are installed inside the waterproof sleeve near the steel dam side. A sealing sleeve and oil-impregnated asbestos filler are sequentially installed inside the waterproof sleeve on the other side of the frameless oil seal. The frameless oil seal, O-ring, sealing sleeve, and oil-impregnated asbestos filler are in close contact with the bottom shaft to ensure a sealing effect. A pressure plate sleeve is installed at the other end of the waterproof sleeve. One end of the pressure plate sleeve extends into the waterproof sleeve and is tightly pressed against the oil-impregnated asbestos filler, limiting the position of the oil-impregnated asbestos filler in the waterproof sleeve and preventing it from detaching. The pressure plate sleeve and the waterproof sleeve are connected together by multiple bolts, with nuts tightly fitted on the bolts to ensure a reliable connection between the pressure plate sleeve and the waterproof sleeve.

[0008] Preferably, an arc-shaped locking mechanism is fixedly installed on the inner wall of the concrete pile located outside the bottom shaft. The locking mechanism has a plurality of first insertion holes evenly distributed on it, and a second insertion hole is provided on the crank arm. The positions of the first insertion holes and the second insertion holes are opposite and have the same diameter. An insertion rod is provided through the first insertion hole and the second insertion hole. The hydraulic rod mechanism drives the bottom shaft to rotate through the crank arm. When the steel dam moves to the designated position, the insertion rod is inserted into the first insertion hole and the second insertion hole to ensure the stability of the crank arm position, thereby ensuring the stability of the steel dam position.

[0009] Preferably, a water-blocking plate is fixedly installed on the concrete river surface on the side of the bottom shaft closest to the river surface. The end of the water-blocking plate is made of rubber and is tightly connected to the bottom shaft to prevent river water from leaking from the bottom shaft.

[0010] Preferably, multiple anti-vibration piers are uniformly fixed on the concrete river surface on one side of the bottom axis, and a buffer pad is fixedly installed on the upper end of the anti-vibration pier. When the steel dam is in a horizontal state, the inner wall of the steel dam is pressed against the buffer pad, and the anti-vibration piers support the steel dam to ensure the stability of the steel dam's position.

[0011] Preferably, the height of the concrete river surface on one side of the steel dam is higher than the height of the concrete river surface on the other side of the anti-seismic pier, ensuring that when the bottom shaft drives the steel dam to rotate and make the steel dam horizontal, the river water flows out from above the steel dam.

[0012] Preferably, the height of the base is higher than the height of the bottom shaft, which facilitates the movement of the crank arm and the hydraulic rod mechanism at different angles.

[0013] The beneficial effects of this utility model are as follows: the bottom shaft is reliably supported by multiple hinge seats, and the steel dam is rotated by the bottom shaft. A hydraulic rod mechanism is set on the base in the cavity, which not only ensures the stability of the position of the hydraulic rod mechanism, but also allows the hydraulic rod mechanism to rotate within a certain angle along the shaft. One end of the crank arm is reliably connected to the bottom shaft, and the other end is hinged to the end of the hydraulic rod mechanism. The hydraulic rod mechanism drives the crank arm to move, and then drives the steel dam to rotate through the bottom shaft. This avoids the corrosion of the hydraulic rod mechanism and ensures the normal use of the steel dam. Attached Figure Description

[0022] To better understand the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, further illustrates this utility model.

[0023] like Figure 1-7 The steel dam driven by a bottom shaft shown includes a cylindrical bottom shaft 1. Multiple hinge seats 2 are uniformly fixed on the concrete river surface below the bottom shaft 1. A semi-circular groove 3 is formed at the middle of the upper end of each hinge seat 2. The diameter of the groove 3 is the same as the diameter of the bottom shaft 1. The bottom shaft 1 corresponds to the groove 3 and is positioned within the groove 3. The multiple hinge seats 2 reliably support the bottom shaft 1, allowing it to rotate smoothly within the groove 3. One end of the bottom shaft 1 is fixedly connected to a steel dam 4, forming an integral structure with the bottom shaft 1. The bottom shaft 1 drives the steel dam 4 to rotate. Concrete piles 5 are provided at both ends of the steel dam 4. A cavity 6 is formed in the middle of each concrete pile 5. A base 7 is fixedly provided on one side of the cavity 6 to raise the height of the hydraulic rod mechanism 10. A base 8 is fixedly provided on the upper end of the base 7, with a height higher than that of the bottom shaft 1, facilitating the angular movement of the crank arm 13 and the hydraulic rod mechanism 10. The base 8 has vertically symmetrically fixed frame plates 9 on both sides of its upper end. A hydraulic rod mechanism 10 is arranged between the frame plates 9. A block 11 is fixedly arranged on the outer wall of the hydraulic rod mechanism 10 located between the frame plates 9. A shaft 12 is horizontally symmetrically fixed at the middle position of both ends of the block 11. A shaft hole is opened at the middle position of the frame plate 9. The end of the shaft 12 passes through the center of the bearing in the shaft hole and is fixedly connected to the bearing. This ensures that the hydraulic rod mechanism 10 can be reliably connected to the base 8, guaranteeing the stability of the position of the hydraulic rod mechanism 10, and also allows the hydraulic rod mechanism 10 to move along the shaft 12. The shaft rotates within a certain angle. The end of the bottom shaft 1 passes tightly through the through hole on the concrete pile 5 and is located in the cavity 6. A crank arm 13 is provided in the cavity 6. One end of the crank arm 13 has a sleeve hole 14. One end of the bottom shaft 1 passes through the sleeve hole 14 and is fixedly connected to the crank arm 13. The other end of the crank arm 13 is hinged to the end of the hydraulic rod mechanism 10. The hydraulic rod mechanism 10 drives the crank arm 13 to move, which in turn drives the bottom shaft 1 to rotate. When the hydraulic rod mechanism 10 is in its shortest state, the steel dam 4 is in a vertical state; when the hydraulic rod mechanism 10 is in its longest state, the steel plate 4 is in a horizontal state.

[0024] An arc-shaped groove 15 is provided on the side wall of the concrete pile 5 near the steel dam 4. The groove 15 corresponds to the position of the steel dam 4. The end of the steel dam 4 is located in the groove 15. The groove 15 limits the position of the end of the steel dam 4. The end of the steel dam 4 is in reliable contact with the groove 15 to prevent water seepage.

[0025] A waterproof sleeve 16 is fixedly installed inside the through hole of the concrete pile 5 to prevent water from entering the cavity 6. A frameless oil seal 17 and an O-ring 18 are installed inside the waterproof sleeve 16 near the steel dam 4. A sealing sleeve and an oil-impregnated asbestos filler 20 are installed in sequence inside the waterproof sleeve 16 on the other side of the frameless oil seal 17. The frameless oil seal 17, O-ring 18, sealing sleeve 19, and oil-impregnated asbestos filler 20 are in close contact with the bottom shaft 1 to ensure a sealing effect. A pressure plate sleeve 21 is installed at the other end of the waterproof sleeve 16. One end of the pressure plate sleeve 21 extends into the waterproof sleeve 16 and is tightly pressed against the oil-impregnated asbestos filler 20 to limit the position of the oil-impregnated asbestos filler 20 in the waterproof sleeve 16 and prevent it from detaching from the waterproof sleeve 16. The pressure plate sleeve 21 and the waterproof sleeve 16 are connected together by multiple bolts 22. Nuts are tightly fitted on the bolts 22 to ensure a reliable connection between the pressure plate sleeve 21 and the waterproof sleeve 16.

[0026] An arc-shaped locking mechanism 23 is fixedly installed on the inner wall of the concrete pile 5 located outside the bottom shaft 1. The locking mechanism 23 has a plurality of first insertion holes 24 evenly distributed on it, and a second insertion hole 25 is provided on the crank arm 13. The positions of the first insertion holes 24 and the second insertion holes 25 are opposite and have the same diameter. Insert rods are provided through the first insertion holes 24 and the second insertion holes 25. The hydraulic rod mechanism 10 drives the bottom shaft 1 to rotate through the crank arm 13. When the steel dam 4 moves to the designated position, the insert rods are inserted into the first insertion holes 24 and the second insertion holes 25 to ensure the stability of the crank arm 13, thereby ensuring the stability of the position of the steel dam 4.

[0027] A water-blocking plate 26 is fixedly installed on the concrete river surface on the side of the bottom shaft 1 closest to the river surface. The end of the water-blocking plate 26 is made of rubber and is tightly connected to the bottom shaft 1 to prevent river water from leaking from the bottom shaft 1.

[0028] Multiple anti-vibration piers 27 are evenly fixed on the concrete river surface on one side of the bottom shaft 1. A buffer pad is fixedly installed at the upper end of each anti-vibration pier 27. When the steel dam 4 is in a horizontal state, the inner wall of the steel dam 4 abuts against the buffer pad, and the anti-vibration piers 27 support the steel dam 4, ensuring its stability. The height of the concrete river surface on one side of the steel dam 4 is higher than the height of the concrete river surface on the side of the anti-vibration piers 27, ensuring that when the bottom shaft 1 rotates the steel dam 4 to a horizontal state, the river water flows out from above the steel dam 4.
