Description

Technical Field

[0001] This utility model relates to the field of river-crossing bridge technology, and in particular to a blocking block for reducing the impact of water backing up on river-crossing bridge piers. Background Technology

[0002] Bridges generally refer to structures built over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. To adapt to the modern, rapidly developing transportation industry, bridges have also been extended to refer to buildings that cross mountain streams, unfavorable geological conditions, or meet other transportation needs to make travel more convenient. Bridges are subject to the impact of river and sea water over a long period of time. When rivers rise, the speed of the water flow increases, which intensifies the impact on the bridge, causing the bridge supports to be subjected to greater negative pressure and load, making the overall support of the bridge unstable.

[0003] Most existing river-crossing bridges have curved water-facing blocks around their sides, using their slopes to buffer the impact of the river water.

[0004] An existing patent (publication number: CN209703278U) discloses a blocking block to reduce the impact of water on bridges crossing rivers. The blocking block, consisting of a blocking block, a water-facing surface, a flexible filling layer, and buffer bars, is installed around the outer perimeter of the bridge. When river water flows over the bridge, it flows towards the water-facing surface, whose arc shape buffers the impact of the water. Furthermore, when the water-facing surface is subjected to the impact of the water, its inner wall presses tightly against the flexible filling layer, causing the impact to be deflected. The buffer bars, located between the flexible filling layers, provide stress buffering, further reducing the impact force of the river water. Therefore, the impact force of the river water will not directly affect the bridge, protecting the bridge's support structure and improving the safety of the bridge deck.

[0005] Existing patents offer solutions to the above problems, but their protective effects are inadequate. In actual use, due to the lack of a diversion structure, the impact load of the water flow cannot be quickly reduced, causing the bridge piers to continuously bear strong impacts, shortening their service life, affecting the overall safety and stability of the bridge operation, and reducing the practicality of the device.

[0006] To address this, a blocking block is proposed to reduce the impact of water backflow on bridge piers across rivers. Utility Model Content

[0007] The purpose of this invention is to provide a blocking block that reduces the impact of water backflow on bridge piers in river crossings. This invention addresses the problem that existing bridges have poor protection effects and, in actual use, lack diversion structures, cannot quickly weaken the impact load of water flow, causing the bridge piers to continuously bear strong impacts, shortening their service life, affecting the overall safety and stability of bridge operation, and reducing the practicality of the device.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a blocking block for reducing the impact of water backlog on bridge piers in river crossings, comprising a bridge pier body, a beam body fixedly connected to the bottom of the bridge pier body, a buffer assembly fixedly connected to the surface of the beam body, and a diversion assembly fixedly connected to the top of the buffer assembly, the diversion assembly comprising a fixed pipe, a fixed ring fixedly connected to the top and bottom of the fixed pipe, and the fixed pipe being sleeved on the surface of the beam body, a plurality of connecting rods fixedly connected between opposite sides of the two fixed rings, a plurality of rotating blades rotatably connected to the surface of the connecting rods, and the connecting rods being distributed in a ring between the two fixed rings.

[0009] Preferably, the buffer assembly includes an annular base, an arc-shaped blocking block is fixedly connected to the top of the annular base, and the annular base is fixedly connected to the surface of the beam. The arc-shaped blocking block has a fixing hole inside, and a buffer rubber is fixedly connected inside the fixing hole. Annular plates are fixedly connected to the top and bottom of the buffer rubber, and several reinforcing rods are fixedly connected between the two annular plates.

[0010] Preferably, the buffer rubber has a fixing groove inside, and the annular plate and the reinforcing rod are located inside the fixing groove.

[0011] Preferably, the outer surface of the arc-shaped blocking block is coated with a corrosion-resistant coating.

[0012] Preferably, the top and bottom of the rotating blade are both fixedly connected with annular stripping blades.

[0013] Preferably, the rotating blade is made of stainless steel, and the surface of the rotating blade is coated with an anti-corrosion coating.

[0014] Preferably, a reinforcing base is fixedly connected to the side of the beam away from the main body of the pier, and several fixing rods are fixed to the top of the reinforcing base. The side of the fixing rods away from the reinforcing base is fixedly connected to the annular base, and the fixing rods are distributed in a ring on the top of the reinforcing base.

[0015] Preferably, the top of the reinforcing base is provided with an installation groove for use with the beam, and the surface of the beam is in contact with the inner wall of the installation groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By setting up a buffer component, this application can increase the contact area of ​​the water flow and disperse the local impact force through the arc-shaped blocking block. Combined with the elastic deformation of the buffer rubber to absorb the impact kinetic energy of the water flow, and with the help of the rigid protective component composed of the annular plate and the reinforcing rod, it can effectively block the transmission of impact, greatly reduce the direct force of the water flow on the main body of the bridge pier, and improve the stability of the device.

[0018] 2. By setting up a diversion component, this application can receive water flow through annularly distributed rotating blades. The water flow thrust drives the rotating blades to rotate, diverting the concentrated water flow that vertically impacts the main body of the bridge pier to the surrounding areas laterally. This reduces the pressure of the water flow's frontal impact and breaks up local eddies through the generated turbulence, preventing the accumulation of impact energy. At the same time, the annular stripping blades clear aquatic plants and floating debris to prevent channel blockage, breaking the conditions for water accumulation and energy retention at the source, thus improving the practicality of the device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] A blocking block for reducing the impact of water backlog on bridge piers in river crossings includes a pier body 1, a beam 2 fixedly connected to the bottom of the pier body 1, a buffer assembly 3 fixedly connected to the surface of the beam 2, and a diversion assembly 4 fixedly connected to the top of the buffer assembly 3. The diversion assembly 4 includes a fixed pipe 401, with fixed rings 402 fixedly connected to both the top and bottom of the fixed pipe 401. The fixed pipe 401 is sleeved on the surface of the beam 2. Several connecting rods 403 are fixedly connected between opposite sides of the two fixed rings 402. Several rotating blades 404 are rotatably connected to the surface of the connecting rods 403, and the connecting rods 403 are distributed in a ring between the two fixed rings 402.

[0028] In this embodiment: the combined use of the arc-shaped blocking block 302 and the buffer rubber 304 not only increases the water flow contact area to disperse local impact force, but also utilizes the elasticity of the buffer rubber 304 to buffer and disperse the impact of the water flow. At the same time, the rigid protective structure formed by the annular plate 305 and the reinforcing rod 306 can effectively block the impact of the water flow and limit excessive deformation of the rubber, ensuring the stability of the buffer structure and significantly reducing the direct force of the water flow on the pier body 1, thus improving the stability and reliability of the buffer component 3. Then, through the combined use of the connecting rod 403 and the rotating blade 404, the rotating blade 404 can rotate smoothly on the surface of the connecting rod 403. When the water flow pushes the rotating blade 404 to rotate, it can divert the concentrated water flow that vertically impacts the pier body 1 to the surrounding areas laterally. No additional power is required; automatic diversion can be achieved solely by the water flow. This reduces the pressure of the water flow's frontal impact and breaks the formation of local eddies through the continuous turbulence generated by the rotation, preventing the continuous accumulation of impact energy and ensuring the long-term safe and normal use of the bridge. This also improves the ease of use of the diversion component 4.

[0029] Specifically, such as Figure 4 As shown, the buffer assembly 3 includes an annular base 301, an arc-shaped blocking block 302 is fixedly connected to the top of the annular base 301, and the annular base 301 is fixedly connected to the surface of the beam 2. The arc-shaped blocking block 302 has a fixing hole 303 inside, and a buffer rubber 304 is fixedly connected inside the fixing hole 303. The top and bottom of the buffer rubber 304 are fixedly connected to annular plates 305, and several reinforcing rods 306 are fixedly connected between the two annular plates 305.

[0030] Specifically, such as Figure 5 As shown, the buffer rubber 304 has a fixing groove 5 inside, and the annular plate 305 and the reinforcing rod 306 are located inside the fixing groove 5.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the outer surface of the arc-shaped blocking block 302 is coated with a corrosion-resistant coating.

[0032] In this embodiment: the fixing groove 5 provides a stable installation space for the annular plate 305 and the reinforcing rod 306, allowing the buffer rubber 304 to be tightly connected to it, forming a composite structure. The buffer rubber 304 can absorb the impact of the water flow, while the reinforcing rod 306 can block the impact and limit excessive deformation of the rubber, ensuring the stability of the structure. At the same time, the corrosion-resistant coating on the outer surface of the arc-shaped blocking block 302 can effectively isolate the erosion of river water and silt, reduce the wear and corrosion of the arc-shaped blocking block 302 caused by water flow, extend its service life, ensure the stable operation of the buffer assembly 3, and improve the stability and reliability of the buffer assembly 3.

[0033] Specifically, such as Figure 2 , Figure 4 As shown, the top and bottom of the rotating blade 404 are fixedly connected with annular stripping blades 6.

[0034] Specifically, such as Figure 4 As shown, the rotating blade 404 is made of stainless steel, and the surface of the rotating blade 404 is coated with an anti-corrosion coating.

[0035] In this embodiment: by using the rotating blade 404 in conjunction with the annular stripper 6, the rotating blade 404 is driven to rotate by the water flow, which in turn drives the annular stripper 6 to rotate. This can cut and scrape away aquatic plants and floating debris in the river channel, preventing debris from entangled or blocking the diversion channel and ensuring the continuous and smooth operation of the diversion component 4. At the same time, the rotating blade 404 is made of stainless steel and coated with anti-corrosion paint, which can effectively resist the impact of river water to ensure structural stability, as well as resist corrosion and rust in the humid environment of the river channel, significantly extending the service life of the rotating blade 404 and improving the ease of use of the diversion component 4.

[0036] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a reinforcing base 7 is fixedly connected to the side of the beam 2 away from the pier body 1, and several fixing rods 8 are fixed to the top of the reinforcing base 7. The side of the fixing rods 8 away from the reinforcing base 7 is fixedly connected to the annular base 301, and the fixing rods 8 are distributed in a ring on the top of the reinforcing base 7.

[0037] Specifically, such as Figure 3 As shown, the top of the reinforcing base 7 is provided with an installation groove 9 for use with the beam 2, and the surface of the beam 2 is in contact with the inner wall of the installation groove 9.

[0038] In this embodiment: the beam 2 and the mounting groove 9 work together to make the beam 2 and the reinforcing base 7 tightly connected, which can effectively block external impacts and ensure the stable operation of the equipment. At the same time, with the help of the ring-shaped fixed rods 8, the water flow impact force borne by the buffer component 3 can be evenly distributed to the reinforcing base 7 to form a multi-directional force support structure, avoiding connection loosening or structural deformation caused by local stress concentration, further enhancing the connection strength of the device and improving the stability of the device.

[0039] Working principle: When protecting the bridge pier, as the river water flows towards the main body 1 of the pier, it first contacts the annularly distributed rotating blades 404. The thrust of the water flow drives the rotating blades 404 to rotate smoothly around the connecting rod 403, which can divert the concentrated water flow that originally impacts the main body 1 of the pier laterally. No additional power is required; the diversion is achieved automatically by relying solely on the water flow. This reduces the pressure of the water flow's frontal impact and breaks up the formation of local eddies through the continuous turbulence generated by the rotation, preventing the continuous accumulation of impact energy and ensuring the long-term safe and normal use of the bridge. When the rotating blades 404 rotate, they simultaneously drive the annular stripping blades 6 at their top and bottom to rotate synchronously, which can cut and scrape away aquatic plants and floating debris in the river in real time, preventing blockage of the diversion channel. The impact force of the water flow has been greatly weakened and then acts on the arc-shaped blocking block 302. Its arc-shaped surface can increase the contact area of ​​the water flow and further disperse the local impact force. The impact of the water flow causes the buffer rubber 304 to deform, which can absorb the remaining impact kinetic energy. With the help of the rigid protective structure formed by the annular plate 305 and the reinforcing rod 306, the impact of the water flow can be effectively blocked and the excessive deformation of the rubber can be limited, ensuring the stability of the buffer structure and greatly reducing the direct force of the water flow on the main body of the pier 1. In this process, the ring-shaped fixed rods 8 can evenly distribute the impact force borne by the buffer component 3 to the reinforcing base 7, forming a multi-directional force support, preventing the buffer structure from loosening or deforming, and thus greatly reducing the impact of the backwater impact on the main body of the pier 1.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
