DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.
[0019] Embodiment one: please refer to Figures 1-4 , a kind of bridge pier column debris flow shunt fin impact-resistant structure in the figure, including two blocking columns 1 fixed on the bearing platform, two blocking columns 1 outside are sleeved with impact-resistant plate 2, two impact-resistant plates 2 are butt jointed by bolt 3, further including two mounting rods 4 arranged at the front end of impact-resistant plate 2, two mounting rods 4 outside are rotatably sleeved with shunt plate 5, shunt plate 5 is fixed with several shunt fins 6, and fixed plate 7 is fixed on impact-resistant plate 2, adjusting rod 8 is rotatably installed on fixed plate 7, the bottom of adjusting rod 8 is fixed with rotating part 9, the top of adjusting rod 8 is fixed with adjusting part 10, shunt plate 5 is swung by adjusting part 10; In the scheme, two impact-resistant plates 2 are designed to be sleeved outside two blocking columns 1, so as to realize the protection of the bridge pier column, when the water flow impacts, the impact-resistant plate 2 can be used to play the impact-resistant effect, to avoid the damage caused by the debris in the water flow impacting the bridge pier column, and at the same time, in the water flow impact process, rotating part 9 is driven to swing adjusting part 10 to shunt plate 5, and the swing of shunt plate 5 is used to avoid vortex outside impact-resistant plate 2.
[0020] Please refer to Figure 2 Figure 4 , the anti-impact plate 2 is composed of a V-shaped plate 11 and butt plates 12 fixed at both ends of the V-shaped plate 11, the butt plates 12 are provided with notches 13 for mounting bolts 3, and a mounting rod 4 is mounted at the outer end of the V-shaped plate 11, wherein, in order to avoid the direct impact of water flow on the mounting rod 4, a tapered end 14 is fixed at the outer end of the V-shaped plate 11, and the tapered end 14 is used to divide the incoming water flow. In the present scheme, the tapered end 14, the V-shaped plate 11 and the butt plates 12 at both ends jointly form a tapered flow dividing structure to divide the water flow to both sides, effectively avoiding the impact of water flow on the bridge pier column and the damage of debris in the water flow to the bridge pier column.
[0021] It should be noted that the inner side of the V-shaped plate 11 is provided with a circular arc structure 26 matched with the stop column 1, and the circular arc structure 26 is designed to closely fit the stop column 1.
[0022] Further, referring to Figure 2 - Figure 5 , the rotating part 9 includes a rotating impeller 15 mounted at the bottom of the adjusting rod 8, which is rotated by the impact of water flow to drive the adjusting rod 8 to rotate; Among them, referring to Figure 4 - Figure 7 , the adjusting part 10 includes an adjusting wheel 16 fixed at the top of the adjusting rod 8, the adjusting wheel 16 is fixed with a butt column 17, the butt column 17 is fixed with a connecting rod 18, the V-shaped plate 11 is fixed with a guide rod 19, the guide rod 19 is slidably sleeved with a sleeve 20, the bottom of the sleeve 20 is fixed with a linkage column 21 rotatably connected with the connecting rod 18, and the outer side of the sleeve 20 and the outer side of the flow dividing plate 5 are fixed with a butt piece 22. It should be noted that when the adjusting rod 8 rotates due to the rotation of the rotating impeller 15, the adjusting wheel 16 will rotate, causing the butt column 17 to move in a circular motion along the adjusting rod 8, causing the connecting rod 18 to swing, causing the linkage column 21 to drive the sleeve 20 to move along the outer side of the guide rod 19, and under the action of the butt piece 22, the flow dividing plate 5 swings.
[0023] Further, referring to Figure 5 - Figure 7 , the butt piece 22 includes a driving plate 23 fixed on the outer side of the sleeve 20 and a buckling plate 24 fixed on the outer side of the flow dividing plate 5, the inner side of the buckling plate 24 abuts against the outer side of the driving plate 23, and it should be noted that when the sleeve 20 moves along the guide rod 19, the driving plate 23 will move synchronously, the driving plate 23 first pushes the buckling plate 24 outward to make the flow dividing plate 5 swing outward, and then after the sleeve 20 resets along the guide rod 19, the water flow will impact the flow dividing plate 5 to make the flow dividing plate 5 reset, and the operation is rotated in turn, so as to realize the cyclic swinging operation of the flow dividing plate 5, which can effectively avoid the vortex formed on both sides of the anti-impact plate 2.
[0024] In the scheme, a plurality of shunt openings 25 are formed on the shunt plate 5. The shunt openings 25 are designed to allow water flow, reducing the resistance when adjusting the shunt plate 5. The shunt plate 5 is made of fiber-reinforced composite material, which has the hardness of rigid material and lighter weight, making it more convenient to adjust and swing.
[0025] In addition, referring to Figure 5 Figure 7 The buckle plate 24 is located at the middle outer end of the shunt plate 5, so that when the belt plate 23 moves, the buckle plate 24 moves, making the swing of the shunt plate 5 more stable.
[0026] In the operation of the bridge pier column impact resistance, the impact resistance plate 2 is assembled first. The personnel puts two impact resistance plates 2 outside the two blocking columns 1, and uses the bolts 3 to limit the two impact resistance plates 2. When the water flow impacts in two directions of the two impact resistance plates 2, the blocking column 1 can have good limiting effect, ensuring the overall strength of the impact resistance plate 2, and being detachably installed, making it more convenient for subsequent replacement and maintenance. When the water flow impacts, the water flow will first impact the impact resistance plate 2 to protect the bridge pier column. At the same time, the water flow will drive the rotating impeller 15 to rotate. Under the rotation of the adjusting rod 8, the adjusting wheel 16, the butt joint column 17, the connecting rod 18 and the sleeve pipe 20 slide along the guide rod 19 to do the sliding crank action, and under the action of the butt joint 22, the shunt plate 5 swings correspondingly, which can effectively eliminate the vortex generated on both sides of the impact resistance plate 2, avoid the vortex lifting the silt at the bottom of the bridge pier column, and avoid the phenomenon of local bed surface being hollowed out, improving the stability of the bridge pier column.
[0027] Embodiment two: please refer to Figure 4 The embodiment further illustrates embodiment one, and the difference lies in that the structure of the blocking column 1 is optimized to limit the impact resistance plate 2 from above.
[0028] Specifically, the blocking column 1 is provided with an installation hole 27, and a limiting rod 28 is inserted into the installation hole 27 to limit the height of the V-shaped plate 11. In the scheme, after the impact resistance plate 2 is installed, in order to avoid the phenomenon of floating caused by the impact of the water flow, the limiting rod 28 is inserted into the blocking column 1 to limit the impact resistance plate 2. At the same time, when the impact resistance plate 2 is disassembled and replaced, only the limiting rod 28 needs to be removed, so that the two butt-jointed impact resistance plates 2 can be easily disassembled.
