Description

Technical Field

[0001] This utility model belongs to the field of gate technology, and in particular relates to a hydraulic steel dam. Background Technology

[0002] A sluice gate 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. In rivers, sluice gates are generally used to intercept water flow. When the water level in the river is high, the sluice gate is opened upwards to discharge water. However, the size of the sluice gate is fixed, and the amount of water discharged per unit time is relatively small, making it impossible to discharge large amounts of water in a short period. Utility Model Content

[0003] To address the above problems, this utility model provides a hydraulic steel dam.

[0004] This utility model is implemented as follows: A hydraulic steel dam includes a middle steel plate and side steel plates. Concrete piles are vertically fixed on the concrete river channel on the side of the side steel plate away from the middle steel plate. A shaft is horizontally fixed between the bottoms of the concrete piles to ensure the stability of the shaft position. Multiple sleeves are tightly and evenly fitted on the shaft. One end of the middle steel plate and the side steel plate is fixedly connected to the sleeves. The middle steel plate and the side steel plate rotate within a certain angle along the shaft under the action of the sleeves. Multiple hinge seats are evenly fixed on the concrete river surface directly below the sleeves. A semi-circular groove is formed in the middle of the upper end of each hinge seat. The outer diameter of the sleeve is the same as the diameter of the groove. The sleeve and the groove are positioned correspondingly and the sleeve is set in the groove. The sleeve is reliably supported by the hinge, which ensures that the sleeve rotates smoothly in the groove and prevents the shaft from bending under the heavy pressure of the middle steel plate and the side steel plate. Multiple bases are evenly fixed on the concrete surface on one side of the hinge. The bases are hinged to one end of the hydraulic rod mechanism to limit the position of one end of the hydraulic rod mechanism. The inner walls of the middle steel plate and the side steel plate are hinged to the other end of the hydraulic rod mechanism. The middle steel plate and the side steel plate move up and down under the action of the hydraulic rod mechanism.

[0005] Preferably, rubber sealing gaskets are fixedly installed at both ends of the intermediate steel plate and both ends of the side steel plate to ensure tight contact between intermediate steel plates, between intermediate steel plates and side steel plates, and between side steel plates and concrete piles, so as to prevent water leakage.

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

[0007] Preferably, multiple anti-vibration piers are uniformly fixed on the concrete river surface on the side of the hydraulic rod mechanism away from the sleeve to support the middle steel plate and the side steel plate. The distance between the anti-vibration piers and the sleeve is less than the width of the middle steel plate and the side steel plate to ensure reliable contact between the middle steel plate and the side steel plate and the anti-vibration piers. When the middle steel plate and the side steel plate tilt downward to a horizontal state under the action of the hydraulic rod mechanism, the inner wall of the middle steel plate and the side steel plate is reliably supported together with the anti-vibration piers.

[0008] Preferably, a hydraulic pipeline trench is provided in the concrete river channel between the base and the anti-vibration pier for laying multiple hydraulic pipes. Multiple hydraulic pipes are installed in the hydraulic pipeline trench, and the hydraulic pipes are connected to the hydraulic rod mechanism.

[0009] Preferably, the height of the concrete river surface on one side of the intermediate steel plate is higher than the height of the concrete river surface on the other side of the anti-seismic pier.

[0010] Preferably, the sleeves are tightly fitted together, and a sealing ring is fixedly provided at the end of the sleeve near the concrete pile. The end of the sealing ring abuts against the concrete pile, which not only prevents the sleeve from contacting the concrete pile and causing wear, but also prevents water leakage and corrosion of the shaft.

[0011] The beneficial effects of this utility model are: the middle steel plate and the side steel plate move up and down under the action of the hydraulic rod mechanism. When the water volume is small, only one middle steel plate or side steel plate needs to be opened to meet the drainage requirements. When the water volume is large, all the middle steel plates and side steel plates can be opened, and a large amount of water can be discharged in a short time, which greatly improves the drainage efficiency.

[0018] To better understand the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, further illustrates this utility model.

[0019] like Figure 1-5 The hydraulic steel dam shown includes a middle steel plate 1 and side steel plates 2. Rubber sealing gaskets 10 are fixedly installed at both ends of the middle steel plate 1 and both ends of the side steel plates 2 to ensure tight contact between the middle steel plates 1 and each other, between the middle steel plate 1 and the side steel plates 2, and between the side steel plates 2 and the concrete piles 3, preventing water leakage. Concrete piles 3 are vertically fixed on the concrete river channel on the side of the side steel plates 2 opposite to the middle steel plate 1. A shaft 4 is horizontally fixed between the bottoms of the concrete piles 3 to ensure the stability of the shaft 4. Multiple sleeves 5 are tightly and evenly fitted onto the shaft 4, with the sleeves 5 tightly pressed together. A sealing ring 15 is fixedly installed at the end of each sleeve 5 near the concrete pile 3, with the end of the sealing ring 15 abutting against the concrete pile 3. This prevents wear caused by contact between the sleeves 5 and the concrete pile 3, and also prevents water leakage and corrosion of the shaft 4. One end of the intermediate steel plate 1 and the side steel plate 2 are fixedly connected to the sleeve 5. Under the action of the sleeve 5, the intermediate steel plate 1 and the side steel plate 2 rotate within a certain angle along the shaft 4. Multiple hinge seats 6 are evenly fixed on the concrete surface directly below the sleeve 5. A semi-circular groove 7 is formed in the middle of the upper end of the hinge seat 6. The outer diameter of the sleeve 5 is the same as the diameter of the groove 7. The sleeve 5 is positioned corresponding to the groove 7 and is set in the groove 7. The hinge seat 6 reliably supports the sleeve 5. This design ensures that the sleeve 5 rotates smoothly in the groove 7 while preventing the shaft 4 from bending under the heavy pressure of the middle steel plate 1 and the side steel plate 2. Multiple bases 8 are evenly fixed on the concrete surface on one side of the hinge seat 6. The bases 8 are hinged to one end of the hydraulic rod mechanism 9, which limits the position of one end of the hydraulic rod mechanism 9. The inner walls of the middle steel plate 1 and the side steel plate 2 are hinged to the other end of the hydraulic rod mechanism 9. The middle steel plate 1 and the side steel plate 2 move up and down under the action of the hydraulic rod mechanism 9.

[0020] An arc-shaped groove 11 is provided on the outer wall of the concrete pile 3 near the side steel plate 2. The groove 11 corresponds to the position of the side steel plate 2. The end of the side steel plate 2 is set in the groove 11. The groove 11 limits the position of the end of the side steel plate 2. The end of the side steel plate 2 is in reliable contact with the groove 11 to prevent water seepage.

[0021] Multiple anti-vibration piers 12 are evenly fixed on the concrete surface of the hydraulic rod mechanism 9 on the side opposite to the sleeve 5, supporting the intermediate steel plate 1 and the side steel plate 2. The distance between the anti-vibration piers 12 and the sleeve 5 is less than the width of the intermediate steel plate 1 and the side steel plate 2, ensuring reliable contact between the intermediate steel plate 1 and the side steel plate 2 and the anti-vibration piers 12. When the intermediate steel plate 1 and the side steel plate 2 tilt downwards to a horizontal state under the action of the hydraulic rod mechanism 9, the inner walls of the intermediate steel plate 1 and the side steel plate 2 are reliably supported together with the anti-vibration piers 12. A hydraulic pipe groove 13 is opened in the concrete channel between the base 8 and the anti-vibration piers 12, and multiple hydraulic pipes 14 are laid in the hydraulic pipe groove 13. The hydraulic pipes 14 are connected to the hydraulic rod mechanism 9. The height of the concrete surface on the side of the intermediate steel plate 1 is higher than the height of the concrete surface on the side of the anti-vibration piers 12.

[0022] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
