Description

Bridge pier protection structure of water transportation channel Technical Field The utility model relates to the technical field of water transport channels, in particular to a bridge pier protection structure of a water transport channel. Background The bridge pier is a sub-building which supports the bridge span structure and transmits constant load and vehicle live load to the foundation, and the bridge abutment is arranged at two sides of the bridge. The bridge pier is arranged between the two bridge abutments. The bridge pier is used for supporting the bridge span structure, and the bridge abutment is used for supporting the bridge span structure, connecting with the embankment and preventing the embankment from sliding on the ground. In order to protect bridge abutment and embankment filling, some protection and diversion projects are often carried out on two sides of the bridge abutment. When the ship is in water transportation, the ship usually needs to pass through a large bridge, and when the ship passes through the bridge, as the bridge is more in number and some bridge piers are arranged densely, the ship can collide with the bridge piers, so that the protection fence is arranged on the surface of the bridge piers, and the current protection fence is provided with a certain height in the using process because of the protection fence, so that the regulation according to the height of the water level is inconvenient, and the water transportation channel bridge pier protection structure is provided. Disclosure of utility model The utility model aims to provide a water-borne channel pier protection structure, which is characterized in that a first protection fence and a second protection fence are always positioned above the water surface through the arrangement of a buoyancy ring, so that the pier body is conveniently protected. In order to achieve the above purpose, the water-borne channel pier protection structure comprises a pier body, wherein a plurality of sliding rods are arranged on the surface of the pier body, sliding grooves are formed in the sliding rods, a first protection fence is arranged on the outer side of the pier body, a buoyancy ring is fixedly connected to the bottom of the first protection fence, a plurality of sliding blocks are fixedly connected to the inner portion of the first protection fence, the sliding blocks are in sliding connection with the inner portion of the sliding grooves, two fixing rings are fixedly connected to the surface of the first protection fence, annular grooves are formed in the surface of the fixing rings, a second protection fence is sleeved on the surface of the first protection fence, two sliding rings matched with the annular grooves are fixedly connected to the inner portion of the second protection fence, a plurality of square grooves are formed in the surface of the second protection fence, and a buffer mechanism is arranged in the square grooves. Preferably, the buffer gear includes the dead lever, dead lever fixed connection is in the inside of square groove, the surface cover of dead lever is equipped with the spring, the top of spring and the inside fixed connection of square groove, the bottom of spring and the top fixed connection of movable block, the surface sliding connection of dead lever has the movable block, the front side of movable block articulates there is the fly leaf, the other end of fly leaf articulates there is the buffer board, the bottom and the second protection of buffer board enclose keep off articulated. Preferably, a plurality of balls are arranged in the sliding ring, and the balls are distributed in an equidistant ring shape. Preferably, both sides of the sliding block are fixedly connected with square sliding bars, and the square sliding bars are in sliding connection in the sliding grooves. Preferably, the buffer plates are arranged in a plurality of equal-distance annular distribution. Preferably, both sides of the sliding rod are fixedly connected with fixing plates, and the inner sides of the fixing plates are arc-shaped. Compared with the prior art, the utility model has the following beneficial effects: According to the utility model, through the arrangement of the buoyancy ring, the buoyancy can be generated by the buoyancy ring, so that the first protection fence and the second protection fence can be driven to slide on the surface of the chute, the first protection fence and the second protection fence are positioned above the water surface all the time, the pier body is protected conveniently, and meanwhile, when the ship extrudes the second protection fence, the sliding ring on the inner side of the second protection fence is connected in a rotating way in the annular groove, so that the effect of unloading is achieved, and the impact force is further reduced.
