Description

Technical Field

[0001] The utility model relates to the technical field of large hydraulic dams, in particular to a lubricating device for supporting rods of large hydraulic dams. Background Art

[0002] A hydraulic dam is a relatively simple movable dam that is widely used in agricultural irrigation, fisheries, ship locks, seawater tidal barriers, urban river landscape projects, and small hydropower stations. The hydraulic lifting dam has a scientific mechanical structure, does not block water, and is not afraid of silt accumulation; it is not affected by floating objects; with minimal water loss, it can easily wash away floating objects upstream and make the river water clear; the dam can be released quickly without affecting flood control safety; and it has a strong ability to resist flood impacts.

[0003] After searching, a Chinese patent discloses a hydraulic rotating rigid support dam (authorization announcement number CN205712000U), which includes a base, a dam body, a mechanical rod, and a hydraulic rod; the dam body is connected to the base through a hinged structure, and the base is a reinforced concrete structure, providing a base for the entire hydraulic dam; the mechanical rod is composed of an upper support rod, a lower support rod and a cross rod, a shaft sleeve is provided at the lower end of the upper support rod, and a shaft sleeve is provided at the upper end of the lower support rod, and the upper support rod and the lower support rod are connected by a cross rod passing through the shaft sleeve and can rotate around the cross rod; the upper end of the upper support rod is movably connected to the upper support rod mounting seat of the dam body, and the lower end of the lower support rod is movably connected to the lower support rod mounting seat of the base; the lower end of the hydraulic rod is mounted on the hydraulic rod mounting seat of the base, and the upper end is connected to the cross rod. Although this patented technology can replace the hydraulic rod support with the rigid support of the support rod, it can greatly reduce the load on the hydraulic rod.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that large hydraulic dams usually divide the support rods into two sections to reduce the difficulty of manufacturing and installation and improve construction efficiency. At the same time, the segmented design is also convenient for later maintenance and replacement. However, after long-term influence of natural environments such as wind, sun, and water, the connection between the upper support rod and the lower support rod will rust. After long-term accumulation, the support rod will not be able to work normally, thereby reducing the service life of the support rod. Utility Model Content
