Hydraulic hinge dam is a form of hinge dam in a landscape dam produced by Rongcheng water conservancy Co., Ltd. It is named hinge dam because the face plate of dam body and foundation can be lifted and lifted under the action of hydraulic rod, which is similar to hinge of doorshaft. Hinge dam is a hydraulic "three hinge point luffing mechanism principle", which is combined with sluice. It is suitable for various water conservancy conditions and geological conditions, and is widely used in river landscape, irrigation and water storage, reservoir expansion and other water conservancy and hydropower, water ecological civilization and urbanization construction projects.

　　Hydraulic hinge dam is a necessary dam type for the construction of water ecology and urbanization civilization. Hinge dam can basically replace rubber dam, which plays a significant role in river regulation, water storage, landscape, flood control and irrigation. The working performance of the new hinge dam equipment is better than that of other equipment, with high strength and strong impact resistance, not afraid of silt and blockage, It is a relatively strong equipment. Even if a large amount of sand and stone is completely buried, it can quickly complete the lifting. Moreover, the use of silt or sand and stone to remove the blockage does not require manual cleaning, which saves a lot of manpower and material resources, and the recovery speed of the river after cleaning is relatively fast.

　　The movable dam technology is a new kind of sluice in recent years, which has occupied a large market in the water conservancy industry. Hinge dam has something in common with a sluice named hinge dam. Both of them use hydraulic cylinders to support the dam surface, so as to raise the dam to retain water and lower the dam to discharge flood. But the reason why the hinge dam is so fast is that the North owner attaches importance to the unique advantages of the hinge dam, mainly as follows:

　　1. The material of hinge dam surface is low carbon alloy steel plate. Through structural calculation and analysis, the steel structure panel and driving mechanism can resist any flood, sand and large floating objects collision, with good stress conditions, strong, and small height difference between the front and back of dam surface. It is especially suitable for cold water and frozen area to solve the problem of frost resistance and resist local ice pressure There is a better solution to the problem of inflation. Under the frost heaving pressure of ice surface, the solid dam body of hinge dam will release the oil pressure in the hydraulic cylinder quickly with the frost heaving, and weaken the force caused by frost heaving, so as to protect the hinge dam from damage.

　　2. The hydraulic cylinder adopts single acting plunger cylinder, and there is only one hydraulic pipeline on each dam surface. The hydraulic pipes are densely distributed at the downstream convenient for maintenance, which can effectively reduce the oil leakage failure point and failure rate. Other parts are configured and easy to replace. The hydraulic oil is low temperature anti-wear type, and the hydraulic oil tank is equipped with deep electric heating device, which can ensure good operation at low temperature.

　　3. In the case of no power and no power source, the automatic dam lowering operation and speed control can be achieved to ensure high reliability and reliability. It is especially suitable for remote mountainous areas without people. Hinge dam is of balanced design. When there is no water retaining, the empty dam can also be lowered. It only needs to manually open the manual valve (without electricity). When the flood level exceeds a certain height of the dam (preset, it will cause the hydraulic pressure to rise. When it exceeds the set pressure, the mechanical relief valve will open for pressure relief (opening control), so that the dam surface of hinge dam will drop and the water level will be maintained; When the large flow of flood through, continuous impact on the dam surface, the hydraulic pressure will rise sharply, at this time, the relief valve (Mechanical) continuously open, the dam surface will orderly and quickly drop.

　　4. The hinge dam adopts concealed support, so the foundation drop between upstream and downstream of the dam surface is small, which is almost the riverbed. For the reconstruction of the old foundation, the excavation weight is very small, which is very suitable for the reconstruction projects of various movable dams, and saves the civil engineering quantity. The split and combined dam face design of hinge dam can effectively solve the problem that the torque of the bottom shaft of the gate of the integrated steel dam is too concentrated, and the length of the single span suit is controlled. The split design of hinge dam disperses the water impact force to each dam face unit, which can prevent the influence of large floating objects, sediment, debris, corrosion and other adverse factors on the components. The dam surface is neat and clean, and different colors, patterns, slogans, etc. can be painted according to the needs of the owners. The dam crest can also be customized with wave shape, wing shape, etc. to form a water carrying effect.

　　5. The automatic control of hinge dam has various views, such as remote control, remote control, network centralization, full-automatic control and manual control on site. There is an interlocking relationship among the three, so users can choose one control at random according to their own needs. Through the remote video network, real-time scene images can be transmitted, which can be integrated into the water clearance measurement and flood control dispatching of local water bureaus. At the same time, the stab control can also protect the hydraulic pump station, mainly including the hydraulic pressure (including pressure sensor and pressure relay, oil level, oil temperature, oil filter blockage, etc.).

　　6. The hinge dam can retain water at any height according to the water storage capacity of the river, and the dam surface can stay and support at any angle range. At the same time, it can also be combined or adjusted synchronously by single or multiple fans according to the actual design, so as to reduce the scouring of water flow to the downstream. All dam surface hundreds of meters can be quickly adjusted into a horizontal line, which is convenient for integrated modular control, forming a beautiful landscape in the paper market river.
