Plug-in locking mechanism for locking cross beam of steel dam

Abstract

The invention discloses the field of steel dams, and particularly relates to a plug-in locking mechanism for locking a cross beam of a steel dam. The plug-in locking mechanism comprises an plug-in structure and a fixing structure, the plug-in structure with a fixing function is inserted into the fixing structure with a sealing function, the plug-in structure comprises a rear seat shaft, an plug-in shaft is mounted in the center of the front end face of the rear seat shaft, a sealing groove is formed in the outer side of the front end face of the rear seat shaft, telescopic grooves are formed in the circumferential array of the side face of the plug-in shaft, telescopic structures are installed in the telescopic grooves, the rear seat shaft is of a cylinder structure, the plug-in shaft is of a hollow cylinder structure, the diameter of the plug-in shaft is smaller than that of the rear seat shaft, the first sealing groove is of a circular ring structure, and the telescopic grooves are of a cuboid structure and penetrate through the plug-in shaft. The plug-in locking mechanism for the locking cross beam of the steel dam has the beneficial effects that the structure of a traditional steel dam locking cross beam is optimized, and installation of the steel dam locking cross beam is more convenient.

Description

technical field [0001] The invention relates to the field of steel dams, in particular to a plug-in locking mechanism for locking beams of steel dams. Background technique [0002] In recent years, high dam projects have developed rapidly, featuring high water head, large single-width discharge, and narrow river valleys. However, some small rivers have small flows and low water levels, and the water levels are subject to large seasonal changes. According to statistics, there are more than 50,000 rivers with a drainage area of ​​more than 100 square kilometers, 1,580 rivers with a drainage area of ​​more than 1,000 square kilometers, and 79 rivers with a drainage area of ​​more than 10,000 square kilometers. In addition to large rivers such as the Yangtze River and the Yellow River, there are also a large number of small and medium-sized rivers in my country. On the other hand, the investment in infrastructure construction of small and medium-sized farmland water conservanc...

Problems solved by technology

[0005]In the prior art, steel dams are formed by connecting gates one by one. It is a waste of time, and at the same time, the connection is easy to rust due to no protection, resulting in component damage; for this reason, the present invention proposes a plug-in locking mechanism for steel dam locking beams to solve the above problems
