Abstract
Description
Technical Field
[0001] The invention relates to the field of cleaning debris on bridge piers, and in particular to a dredging device for preventing debris from accumulating on bridge piers. Background Art
[0002] At present, natural disasters occur frequently, such as strong typhoons, torrential rains, and severe floods. During flood seasons, more trees, dead branches, garbage and other debris flow downstream and are intercepted by gravity-type bridge piers with large water-blocking areas. They are stuck at the piers. When the debris accumulates to a certain extent, the thrust of the water flow and the debris will push the piers, causing the bridge to collapse. Therefore, clearing the debris at the piers is a top priority for protecting the bridge.
[0003] The existing gravity bridge piers are also called solid bridge piers. They are generally made of masonry materials such as stone slabs. They mainly rely on their own gravity to balance external forces, thereby ensuring the strength and stability of the bridge piers. They are composed of a solid structure, mostly trapezoidal cones. This type of bridge pier has high rigidity and strong anti-collision ability, but it also has the defect of a large water blocking area, which can easily cause trees, dead branches, garbage and other floating objects to get stuck at the bridge piers; thus, they can only be cleaned manually after the flood recedes, which still poses a major safety hazard. Summary of the invention
[0004] In order to reduce the accumulation of debris at bridge piers and reduce safety hazards, the present application provides a dredging device that prevents the accumulation of debris at bridge piers.
[0005] The present application provides a dredging device for preventing debris from accumulating on bridge piers, which adopts the following technical solution:
[0006] A dredging device for preventing debris from accumulating on a bridge pier comprises a saddle, a mounting frame, a contact piece and an elastic member, wherein the saddle is used to be installed on one end of the water-facing surface of the bridge pier, the mounting frame is fixedly installed on the saddle, one end of the contact piece is hinged to the mounting frame, and the other end is a free end; the elastic member is arranged between the contact piece and the mounting frame and at one end close to the hinge, and the two ends of the elastic member are respectively installed on the contact piece and the mounting frame.
[0007] By adopting the above technical solution, when debris flows with the water flow to the bridge pier, it will contact the contact piece, and the contact piece will swing and tilt, thereby changing the moving direction of the debris and leaving the corresponding bridge pier. During the flood season or under accidental circumstances, debris will accumulate at the contact piece, but due to the effect of the elastic member, the inclination angle of the contact piece is larger, thereby further reducing the water blocking surface and promoting the flow of debris. When the flood season ends, the debris can be pushed away by the rebound effect of the elastic member, thereby reducing the accumulation of debris at the bridge pier and reducing safety hazards.
[0008] Preferably, the side of the contact piece away from the mounting frame is in an arc shape.
[0009] By adopting the above technical solution, the guidance of debris can be made smoother, and the possibility of debris remaining on the contact piece surface can be reduced.
[0010] Preferably, the contact piece is provided with a plurality of through holes.
[0011] By adopting the above technical solution, water can flow through the through hole to intercept and change the movement trajectory of debris, thereby improving the cleaning effect of the debris.
[0012] Preferably, an adaption groove adapted to the bridge pier is opened on the inner side of the saddle; a plurality of fixing belts for being wound around the bridge pier are respectively provided at both ends of the saddle, one end of the fixing belt is connected to the saddle, and the other ends of the fixing belts located at both ends of the saddle are detachably connected via connecting pieces.
[0013] By adopting the above technical solution, the setting of the adapter groove makes the saddle and the bridge pier cooperate more fully, and then the fixing belt is wrapped around the bridge pier, and the fixing belts at both ends are detachably connected by connecting parts to facilitate disassembly, assembly and replacement.
[0014] Preferably, the bridge pier is provided with a locking groove for the fixing belt to be locked in, a plurality of locking rods are pre-buried in the locking groove along the circumferential direction, and the fixing belt is provided with a locking hole for the locking rod to pass through.
[0015] By adopting the above technical solution, the fixing belt is inserted into the locking groove, and the locking rod passes through the locking hole on the fixing belt, thereby reducing the sliding deviation of the fixing belt on the bridge pier.
[0016] Preferably, a groove wall of the saddle portion located in the locking groove is provided with a rubber layer.
[0017] By adopting the above technical solution, the friction between the saddle and the pier is further improved, and the change in the position of the contact piece caused by the slippage of the saddle and the pier is reduced, thereby reducing the influence on the diversion effect of the debris.
[0018] Preferably, a plurality of fastening screws are prefabricated on both sides of the saddle, and snap-in grooves for the fastening screws to be snapped into are provided on both sides of the mounting frame and corresponding to the positions of the fastening screws, and fastening nuts are threadedly mounted on the fastening screws.
[0019] By adopting the above technical solution, the two sides of the mounting frame are respectively inserted into the two sides of the saddle, so that each fastening screw is inserted into the clamping groove for initial positioning, and then the fastening nut is threadedly installed on the fastening screw to complete the detachable installation of the mounting frame. The installation is stable and convenient.
[0020] Preferably, the contact piece is a skin composite panel.
[0021] By adopting the above technical solution, it has the characteristics of buffering energy absorption, corrosion resistance, fatigue resistance, rebound, and floating on water.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. When debris flows to the bridge pier with the water flow, it will contact the contact piece, which will swing and tilt, thereby changing the moving direction of the debris and leaving the corresponding bridge pier. During the flood season or under accidental circumstances, debris will accumulate at the contact piece, but due to the effect of the elastic piece, the inclination angle of the contact piece is larger, thus further reducing the water blocking surface and promoting the flow of debris. When the flood season ends, the elastic piece can also be used to push the debris away through the rebound effect of the elastic piece, thereby reducing the accumulation of debris at the bridge pier and reducing safety hazards.
[0024] 2. Allow water to flow through the through hole to intercept and change the trajectory of debris, thereby improving the cleaning effect of debris. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] When the contact piece 3 is not working, it is at a 90° angle to the saddle 1; under normal circumstances, due to the effect of water flow, it is slightly deformed and at a 60° angle to the saddle 1. At this time, the debris in the water changes its moving direction through the contact piece 3 and flows away from both sides of the contact piece 3 without getting stuck on the contact piece 3. During the flood season or under accidental circumstances, debris accumulates at the contact piece 3, and the contact piece 3 may even be at a 30° angle to the saddle 1, further reducing the water blocking surface and promoting the flow of debris. It is also possible to wait until the flood season ends and push the debris away through the rebound effect.
