Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic dams, in particular to an integrated hydraulic dam. Background Art

[0002] Hydraulic dam refers to a hydraulic concrete lifting dam, which is a relatively simple movable dam technology in water conservancy technology. It is widely used in agricultural irrigation, fisheries, ship locks, seawater tidal barriers, urban river landscape projects and small hydropower stations. Hydraulic dams, water conservancy landscape movable dams, hydraulic lifting dams, hinged movable dams, collectively referred to as movable dams, use the mechanical principles of dump trucks and combine them with the hydraulic structure of pier dams. They have the dual functions of water retaining and water discharge, and have the incomparable advantage of large spans that conventional sluices cannot match.

[0003] For example, an integrated hydraulic dam with the authorization announcement number "CN210127454U" has solved the problems of the existing integrated hydraulic dam, which is high in cost and troublesome to maintain. The above-mentioned limiting buffer mechanism can not only relieve force and buffer the hydraulic cylinder in multiple directions, but also prevent the hydraulic cylinder from being damaged in the hydraulic cylinder due to insufficient hydraulic strength in the hydraulic cylinder when it is subjected to strong impact. Considering that the existing integrated hydraulic dam is subjected to the impact of water on the dam gate during use, the buffer mechanism can relieve force and buffer, but it is still subjected to the impact of strong water on the dam gate, so that the hydraulic cylinder at the rear end is still impacted, which makes the inside of the hydraulic cylinder prone to wear and tear, resulting in a shortened service life. Utility Model Content

[0004] The utility model aims to solve the problem that the hydraulic cylinder of the existing integrated hydraulic dam is easily worn out, resulting in a shortened service life, and proposes an integrated hydraulic dam.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an integrated hydraulic dam, comprising a dam base and a dam top, the inner wall of the dam top being provided with an adjustment mechanism, the adjustment mechanism comprising a fixed seat, the outer wall of the fixed seat being fixedly connected to the dam top, the inner wall of the fixed seat being fixedly connected to the hydraulic cylinder, the end of the hydraulic cylinder being fixedly connected to the push head, the outer wall of the push head being rotatably connected to a connecting piece, the lower end of the connecting piece being slidably connected to a connecting rod, and the outer wall of the connecting rod being slidably connected to a sealing strip.

[0006] Preferably, the outer wall of the dam top is provided with a connecting mechanism, which includes a bracket, the end of the bracket is fixedly connected to the dam top, the inner wall of the bracket is fixedly connected to the connecting column, the outer wall of the connecting column is fixedly connected to the connecting plate, and the outer wall of the connecting plate is installed with a through hole.

[0007] Preferably, the outer wall of the connecting plate is threadedly connected to the fixing bolt, and the end of the fixing bolt is tightly pressed against the sealing gasket.

[0008] Preferably, the upper end of the dam foundation is fixedly connected to the dam surface, the outer wall of the dam surface is fixedly connected to the protective cap, the inner wall of the protective cap is fixedly connected to the bearing, and the inner wall of the bearing is fixedly connected to the connecting column.

[0009] Preferably, the inner wall of the dam surface is provided with drainage holes, and the surface of the dam surface is provided with a dam outlet.

[0010] Preferably, the outer wall of the bracket is fixedly connected to the dam surface.

[0011] The utility model proposes an integrated hydraulic dam, which has the following beneficial effects: the push head and the connecting piece are pushed to move by the liquid cylinder, and the position of the connecting plate is restricted by the connecting column, so that the connecting piece drives the connecting plate on the connecting rod to deflect at an angle on the connecting column. At this time, the through hole on the connecting plate is in a connected state with the dam mouth on the dam surface, so that water can pass through the through hole and the dam mouth, and the impact force of the water will contact the connecting plate, so that the impact force of the water will not be directly transmitted to the hydraulic cylinder, thereby improving the service life.

[0021] The hydraulic cylinder 302 pushes the push head 303 and the connecting piece 304 to move. The connecting column 402 limits the position of the connecting plate 403, so that the connecting piece 304 drives the connecting plate 403 on the connecting rod 305 to deflect at an angle on the connecting column 402.

[0025] Working principle:

[0026] Switch integrated hydraulic dam working stage

[0027] When the integrated hydraulic dam needs to be operated, the external power supply of the hydraulic cylinder 302 is connected, and the hydraulic cylinder 302 starts to work. The hydraulic cylinder 302 pushes the push head 303 and the connecting member 304 to move. After the connecting column 402 limits the position of the connecting plate 403, the connecting member 304 drives the connecting plate 403 on the connecting rod 305 to move on the connecting column 402. The connecting plate 403 is deflected by the hydraulic cylinder 302. At this time, the through hole 404 on the connecting plate 403 is in communication with the dam opening 11 on the dam surface 7, allowing water to pass through the through hole 404 and the dam opening 11. At this time, it is in the open state. Similarly, when the reverse operation is performed, the sealing gasket 6 on the surface of the connecting plate 403 will fit with the dam opening 11 to achieve sealing of the surface of the dam opening 11. At this time, it is in the closed state, and the water in the through hole 404 flows downward to the drainage hole 10, so that the excess water is discharged from the rear end to keep the inside of the dam surface 7 free of water.
