Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the utility model provides a bridge pier diversion structure, be the bridge pier 1 of cylinder shape including the appearance, the inside axis department of bridge pier 1 is provided with central logical groove 5, and bridge pier 1's lateral wall is offered and is used its axis as center evenly distributed's more than eight diversion flow channels 2 for realize the branch water to each rivers direction water liquid, and central logical groove 5 is through diversion flow channel 2 and outside intercommunication, is provided with steel framework 4 in the bridge pier 1, and the logical groove 5 internal rotation of center is provided with diversion structure 6.

The water diversion structure 6 comprises a rotating shaft 6a, the upper end and the lower end of the rotating shaft 6a are rotatably connected with the upper side and the lower side of the central through groove 5 through bearings, the bearings are waterproof bearings, and a water diversion plate 6b is arranged in the middle of the rotating shaft 6 a. The water diversion plate 6b can rotate around the rotating shaft 6a through the water flow direction, and the function of diversion is achieved.
