External hanging type water surface pier protection device

Abstract

The invention provides an external hanging type water surface pier protection device which effectively solves the problems that water surface garbage is prone to being retained around a pier, the protection means is lag in technology, the efficiency is low, and water surface floating objects seriously threaten the safety of the pier. According to the technical scheme, the device comprises a steelring, a first bevel gear is arranged at the lower end of the steel ring, and a shell is arranged at the upper end of the steel ring; a crushing unit is arranged on the shell and comprises a roller type harmonic speed reducer; a steel wheel is fixed on the shell; a cylindrical flexible gear is arranged, and a second bevel gear is arranged on the flexible gear; a first bevel gear is meshed with thesecond bevel gear; a wave generator comprises two rolling wheels which are arranged on the inner side of the flexible gear and make contact with the inner wall of the flexible gear. A circular housingis arranged on the inner side of the shell, a belt wheel is arranged in the housing, a rotating shaft is arranged on the belt wheel, penetrates through the side wall of the circular housing and the steel wheel corresponding to the rotating shaft in sequence from inside to outside and is arranged on the outer side of the second bevel gear, multiple crushing discs are arranged on the part, locatedon the outer side of the second bevel gear, of the rotating shaft, and multiple wedge-shaped crushing teeth are arranged at the edges of the crushing discs.

Description

technical field [0001] The invention relates to the technical field of water surface pier safety protection, in particular to an externally mounted water surface pier protection device. Background technique [0002] With the development of society, elevated roads can be seen everywhere, but correspondingly there are also a large number of safety hazards, especially the bridge piers built in the river. Especially for bridge piers in deep water areas, garbage in the water tends to gather around the piers, including wood chips, large pieces of plastic, agricultural mulch, and willow branches, which increase the resistance of the piers. If they accumulate for a long time, especially in the rainy season, the impact of water flow Large, it will increase the shaking and vibration of the road surface, seriously threatening the safety of bridges and vehicles, especially high-speed rail. In addition, when the water surface freezes in winter, the expansion of the ice layer will squeez...
