Hydraulic lifting dam At present, it has been widely used in various small and medium-sized rivers. This is a new type of water conservancy equipment. Compared with traditional gate dams, it has advantages in terms of low cost, simple maintenance, simple operation, etc. Of course, the structure of the support pier is simple but not simple. Whether it is reliable in structure or performance, it is a must say advantage of hydraulic lift dams.
When the current normal water retaining and flood blocking work is in progress, the fixed support rod of the hydraulic lift dam has a very large supporting role. The main pressure in this case is from the weight of the gate dam itself and the pressure in the water. So the key to support is the locking device. To prevent the interlock problem of the dam system, which is caused by an independent Hydraulic system Controlled. However, once the hydraulic cylinder pipeline is complex or unreasonable, it is easy to get stuck, so we need to pay attention to this aspect.
In this respect, maintenance is needed. In fact, the maintenance of water conservancy equipment is very important. Some hydraulic lifts can be managed by no one. But in the daily maintenance, we should take the responsibility of inspection and supervision to ensure the normal operation of equipment. current Hydraulic dam The base of hydraulic cylinder components, etc. are basically set at the bottom of stilling basin, where all oil pipes are also located, and there will be water level deposition at this position after operation, so maintenance is a must.
At present, hydraulic lift dams are widely used in various regions without any problems. This is because of their good structural reliability and our technical accumulation in the process of design and construction in accordance with local conditions over the New Year. The safety of hydraulic dam related products has been greatly improved. Although the operation of hydraulic lifting dam is simple, daily maintenance is indispensable and needs to be taken seriously.
Hydraulic lifting dam Water science and technology The movable dam technology is relatively simple, but it is not simple. The mechanical principle of dump truck is ingeniously adopted, combined with the hydraulic structure of buttress dam, which is a new and reliable hydraulic technology. Now it has been widely used in the construction of agricultural irrigation, ship locks, flood control, urban river landscape and small and medium-sized hydropower stations. Compared with traditional dams, it has obvious advantages. It can automatically release the dam for flood discharge like a flap gate dam, and it is better to stick to the riverbed like a rubber dam without blocking water.
The hydraulic lift dam has two functions of water retaining and flood discharge. Its structure is composed of arc dam surface, support rod, hydraulic rod, hydraulic cylinder and Hydraulic pump station form. The hydraulic cylinder can be used to lift the dam to retain water and lower the dam to release flood. The back side is the back side of the active dam surface supported by support rods, forming a stable supporting pier dam. The manual push rod switch is used to control the hydraulic system and manually operate the lifting of the movable dam surface. It can also be combined with PLC to control the center and the buoy sensing device to achieve intelligent management and unmanned management.
In addition, the height of movable water retaining is generally about 3m, and the width is not easy to exceed 50m due to the pressure loss of hydraulic pipeline. The river bed with gentle, not seriously silted and small subsidence geological conditions can be used. It is basically free from the impact of floating objects and has a wide range of use conditions. Moreover, both intelligent management and manual operation are simple and easy, and the cost of maintenance and management is low. The hydraulic lift dam is used for the treatment of small rivers in some cities, which can also be adjusted according to the water regime to form a waterfall landscape and add urban style.
