[0019] Embodiment: see Figs. 1-2 A pier flood prevention baffle structure, comprising a baffle structure standing on the water side of the pier 6, the baffle structure comprising at least one baffle 1, and when the baffle 1 is multiple, the multiple baffles 1 are sequentially spliced around the pier 6, and the adjacent baffles 1 have an included angle; a plurality of protruding structures 4 are distributed at intervals on the water side of the baffle 1, and a plurality of holes 5 are provided at intervals on the baffle 1, and the protruding structures 4 and the holes 5 are arranged at intervals.

[0020] It also includes a bottom plate 2 located on the water side of the pier 6 and fixed to the riverbed, one side of the bottom plate 2 close to the pier 6 is fixedly connected with the bottom of the baffle 1, and the other side extends a certain distance away from the pier 6.

[0021] The baffle 1 can be an arc-shaped plate with a concave side facing the pier 6.

[0022] In the embodiment, the baffle 1 is two flat plates, and the two baffle plates 1 have an included angle so that the cross section of the baffle structure is V-shaped, and the inner concave side faces the pier 6. The protruding structure 4 is a prism or pyramid structure with multiple edges or tips. The protruding structure 4 is linearly spaced along the height direction of the baffle 1, and the holes 5 are correspondingly distributed on the backwater side of the protruding structure 4. The bottom plate 2 is fixed on the riverbed by the connecting piece 3 (rivet), and the upper side plate is inclinedly arranged so that the height between the plate surface and the riverbed gradually decreases in the direction away from the baffle 1. The bottom plate 2 is a fan-shaped structure with the pier 6 as the center.

[0023] In use, the triangular baffle is beneficial to guide the flood to flow away to both sides, and reduce the impact force of the flood on the baffle. The baffle surface arranged vertically is alternately provided with sharp protruding structures and holes. The sharp protruding structures are made of hard material and serve to break up boulders. The holes are for allowing part of the water flow to pass through the vertical baffle, reducing the impact force of the flood on the vertical baffle, dispersing the water flow passing through the vertical baffle, and reducing the impact force of the water flow on the pier. The horizontal bottom plate is fixed with the vertical baffle and is fixed on the riverbed by the rivet. The baffle is fixedly arranged at the water-facing position near the pier. When the flood comes, the water gravity presses the horizontal plate, strengthens the stability of the whole baffle device, and the boulders and the like carried by the flood are broken by the sharp protruding structures on the surface of the vertical baffle and then fall on the horizontal plate, further strengthening the pressure on the bottom plate. Meanwhile, the surface of the bottom plate can also be inclinedly arranged to have a certain water-approaching angle, so that the water flow produces pressure on the surface of the bottom plate, further increasing the stability of the bottom plate and the stability of the baffle device. After the flood peak passes, the baffle device is removed, and the boulders on the bottom plate are cleaned up.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the technical solutions. Those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the present application, and should be covered in the scope of the claims of the present application.
