Description

Technical Field

[0001] The present invention relates to the technical field of bridge pier anti-collision, and particularly relates to a self-floating bridge pier anti-collision system and method. Background Art

[0002] As an important transportation infrastructure, the safety of bridges is directly related to the smoothness of transportation and the safety of people's lives and property. As a key load-bearing structure for supporting the bridge structure, bridge piers are often at risk of being hit by waterborne vehicles such as ships due to operational errors or adverse weather conditions. Therefore, the research and application of bridge pier anti-collision devices have received extensive attention.

[0003] Most traditional bridge anti-collision measures rely on static obstacles such as anti-collision piers and anti-collision walls, or use energy-absorbing materials to absorb impact energy. Moreover, these traditional methods usually have problems such as complex installation and high maintenance costs. The existing bridge pier anti-collision devices have developed rapidly, from traditional static anti-collision structures to complex systems with dynamic adjustment, gradually improving the anti-collision ability and application scope of bridge piers, such as self-floating steel-clad composite anti-collision devices, bridge active ship collision prevention warning systems, intelligent response systems, integrated warning and anti-collision systems, etc.

[0004] However, the existing bridge pier anti-collision devices only protect the bridge piles unidirectionally, and have a poor protection effect on passing ships, which is likely to cause damage to the hull and pose a certain safety hazard, that is, the existing bridge pier protection devices cannot achieve two-way protection. Summary of the Invention

[0006] To achieve the above purpose, the present invention adopts the following technical solutions: A self-floating bridge pier anti-collision system includes a pair of fixed cylinders that are vertically arranged on a pair of bridge piles, and further includes: a fixed belt in a ring structure, on which a plurality of through slots are opened, and a plurality of anti-collision barrels that can float on the water surface are detachably arranged on the outer wall of the fixed belt, and both ends of the fixed belt are sleeved on the pair of fixed cylinders; a fixed frame fixedly arranged between the pair of fixed cylinders, on which a telescopic cylinder is rotatably arranged, and tensioning plates are slidably arranged at both ends of the telescopic cylinder, the tensioning plates respectively abut against the inner wall of the fixed belt, and a deflector is fixedly arranged on both sides of the telescopic cylinder. During impact, the deflector pushes the water flow towards the impact direction.

[0007] Preferably, to facilitate the installation of the telescopic cylinder, there are two groups of the fixed frames, which are respectively fixedly arranged at the top and bottom of the pair of fixed cylinders, and the telescopic cylinder is rotatably arranged between the two groups of fixed frames, and the top and bottom of the telescopic cylinder respectively abut against the inner walls of the two groups of fixed frames.

[0008] In order to ensure that the telescopic cylinder can rotate reliably on the fixed frame and reduce the possibility of falling off, further, rotating shafts are fixedly arranged at both the top and bottom of the telescopic cylinder, rotating holes corresponding to the rotating shafts are formed on the fixed frame, and the rotating shafts are rotatably arranged in the rotating holes.

[0009] In order to enable the telescopic cylinder to maintain a state where its two side surfaces are perpendicular to the central plane of a pair of fixed cylinders, facilitating the tensioning of the fixed belt, further, a limiting shaft is fixedly arranged at the top of the rotating shaft, a clamping groove is formed in the limiting shaft along the diameter direction, a torsion spring is sleeved on the limiting shaft, clamping portions are fixedly arranged at both ends of the torsion spring, and limiting grooves are formed in the inner wall of the rotating hole, and the clamping portions are respectively clamped and connected with the clamping groove and the limiting groove.

[0010] Preferably, a piston cavity is formed in the telescopic cylinder, piston plates are slidably arranged at both ends of the piston cavity, connecting plates are fixedly arranged on the piston plates, and one ends of the connecting plates extending out of the piston cavity are respectively fixedly connected with corresponding tensioning plates.

[0011] Further, a spring is arranged in the piston cavity, two ends of the spring respectively abut against opposite surfaces of the two piston plates, and a transmission medium is filled between the two piston plates.

[0012] Preferably, the anti-collision barrel includes an inner core and an outer shell, the inner core is honeycomb-shaped, and a collapse groove is formed in the outer shell.

[0013] Preferably, the anti-collision barrel has a rounded triangular prism structure.

[0014] Preferably, a rotating groove is formed in the outer wall of the fixed cylinder, the fixed belt is sleeved in the rotating groove, a plurality of guiding grooves distributed along the axis are formed in the inner wall of the fixed cylinder, guide rails are fixedly arranged on the bridge pier, and the guiding grooves are respectively slidably connected with the corresponding guide rails.

[0015] A self-floating bridge pier anti-collision method further includes the following steps: Step 1: At least one floating device having sufficient buoyancy to support itself and arranged around the bridge pier; Step 2: An energy absorption structure is rotatably arranged outside the floating device for absorbing and dispersing the energy generated by impact; Step 3: An elastic structure is arranged between the floating devices.

[0016] Compared with the prior art, the present invention provides a self-floating bridge pier anti-collision system and method, having the following beneficial effects: 1. The self-floating bridge pile anti-collision system is configured by arranging a pair of fixed cylinders to move up and down on the bridge pile, sleeving a fixed belt on the fixed cylinders, and fixedly installing anti-collision barrels that can float on the water surface on the outer wall of the fixed belt. On the one hand, it can automatically adjust the positions of the anti-collision barrels and the fixed sleeves on the bridge pile as the water level changes. On the other hand, when being impacted, the anti-collision barrels and the elastic fixed belt can absorb a certain amount of impact energy, and the fixed belt drives the anti-collision barrels to slide a certain distance. This not only can guide the ship to deviate from the bridge pile, reduce the direct impact force, and protect both the ship and the bridge pile, but also effectively disperses and absorbs the energy, improving the usage effect. 2. The self-floating bridge pile anti-collision system is configured by fixedly installing a fixed frame between the fixed cylinders, rotatably arranging a telescopic cylinder on the fixed frame, slidably arranging tensioning plates for tensioning the fixed belt at both ends of the telescopic cylinder, and fixedly installing deflector plates on both sides of the telescopic cylinder. On the one hand, it can tension the fixed belt to a certain extent and effectively absorb the impact energy. On the other hand, during impact, the telescopic cylinder rotates a certain angle away from the impact point. At this time, the deflector plates can push the water flow towards the impact direction or block the water flow impact generated from the impact point of the fixed belt. Since the deflector plates swing towards the impact point driven by the telescopic cylinder, the water flow generated by the swing collides with the water flow generated by the impact, which can further disperse the energy generated by the impact. 3. The self-floating bridge pile anti-collision system is configured by fixedly installing a limiting shaft on the rotating shaft, sleeving a torsion spring on the limiting shaft, and engaging both ends of the torsion spring with a clamping groove and a limiting groove respectively. When the ship impacts the fixed belt on both sides of the tensioning plate, the telescopic cylinder deflects, and then under the action of the torsion spring, after the ship withdraws, it can drive the telescopic cylinder to return to its position, maintaining a state where its two side surfaces are perpendicular to the central plane of the pair of fixed cylinders, facilitating the tensioning of the fixed belt and improving the usage effect.

[0017] Parts not involved in this device are the same as or can be implemented using the prior art. In the present invention, a fixed belt is sleeved on the fixed cylinder, and anti-collision barrels that can float on the water surface are fixedly installed on the outer wall of the fixed belt. When being impacted, the anti-collision barrels and the elastic fixed belt can absorb a certain amount of impact energy, and the fixed belt drives the anti-collision barrels to slide a certain distance. This not only can guide the ship to deviate from the bridge pile, reduce the direct impact force, and protect both the ship and the bridge pile, but also effectively disperses and absorbs the energy, improving the usage effect.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0021] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0022] Embodiment: Refer to Figures 1 - 6, A self-floating bridge pier anti-collision system, including a pair of fixed cylinders 1 that are vertically arranged on a pair of bridge piers. That is to say, a pair of bridge piers jointly support a bridge pier, and the bridge piers are in the shape of a rotating body cylinder. The pair of fixed cylinders 1 can slide up and down along the axial direction of the bridge piers. Moreover, the closed figure formed by the tangents of the outer walls of the pair of bridge piers is approximately runway-shaped. It also includes: A fixing belt 2 in a ring structure, made of elastic material, such as rubber or nylon or polyurethane. Here, we preferably choose nylon / polyester fabric-reinforced rubber, that is, by sandwiching nylon or polyester fabric between rubber layers, the tear resistance and durability of the product can be significantly improved. It can not only provide the necessary softness to adapt to objects of different shapes, but also ensure sufficient rigidity to prevent excessive deformation. When being impacted, due to its certain elasticity and energy absorption characteristics, it can effectively absorb and disperse the impact energy, improve the anti-collision effect of the bridge pier and the protection ability for ships. A plurality of through slots 201 are opened on the fixing belt 2. The number of through slots 201 is two to two hundred, preferably one hundred. The through slots 201 are arranged in multiple layers and are equally spaced along the axial direction of the fixing belt 2. And a plurality of anti-collision barrels 301 that can float on the water surface are detachably arranged on the outer wall of the fixing belt 2. It can adjust the position of the fixed cylinder 1 on the bridge pier along with the rise and fall of the water level, so that the anti-collision barrels 301 always maintain the best anti-collision posture, which is applicable to different water areas and seasonal conditions, without the need for frequent manual adjustment or maintenance, greatly reducing the operation cost. We preferably choose that one-third of the anti-collision barrel 301 is above the water and two-thirds is below the water, which not only ensures sufficient buoyancy but also provides a good visual marking function. The number of anti-collision barrels 301 is two to fifty, preferably twenty-eight. The anti-collision barrel 301 is in the shape of a rounded triangular prism, and the triangle formed by the cross-section of the triangular prism is an equilateral triangle. Here, a fixing plate 3 is fixedly arranged on the side of the anti-collision barrel 301, and the fixing plate 3 is detachably connected to the outer wall of the fixing belt 2. The fixing plate 3 can be fixed on the fixing belt 2 by bolts or straps or clamps, etc. Here we preferably choose bolts, which can not only fix the anti-collision barrel 301 on the fixing belt 2, but also is convenient for installation and disassembly, facilitating the replacement of the anti-collision barrel 301, and can increase or decrease the anti-collision barrels 301 according to needs to improve the use effect. The two ends of the fixing belt 2 are sleeved on a pair of fixed cylinders 1. That is to say, the fixing belt 2 can slide between the pair of fixed cylinders 1. When a ship hits the anti-collision barrel 301, at this time, the anti-collision barrel 301 can push the fixing belt 2 to slide a certain distance around the outer wall of the fixed cylinder 1. The anti-collision barrel 301 and the elastic fixing belt 2 can absorb a certain amount of impact energy. The fixing belt 2 drives the anti-collision barrel 301 to slide a certain distance, which can guide the ship to deviate from the bridge pier, reduce the direct impact force, and can protect both the ship and the bridge pier, realizing the effective dispersion and absorption of energy and improving the use effect;A fixing frame 101 is fixedly arranged between a pair of fixing cylinders 1. A telescopic cylinder 4 is rotatably arranged on the fixing frame 101. Tensioning plates 5 are slidably arranged at both ends of the telescopic cylinder 4. The outer wall of the tensioning plate 5 is of an arc structure. The tensioning plates 5 are respectively abutted against the inner wall of the fixing belt 2. When in use, by slidably arranging the tensioning plates 5 on the telescopic cylinder 4, the fixing belt 2 can be tensioned to a certain extent. At this time, the fixing belt 2 presents an approximate rounded rhombus structure, which can effectively absorb impact energy. Moreover, dial plates 402 are fixedly arranged on both sides of the telescopic cylinder 4. When the ship impacts the fixing belt 2 on both sides of the tensioning plate 5, the water flow can flow towards the direction of the dial plate 402 under the push of the through groove 201 and the fixing belt 2. Then, due to the impact, the tensioning plate 5 on the impacted side slides into the telescopic cylinder 4, and the tension on the fixing belt 2 on the other side will increase, keeping the fixing belt 2 in a certain tensioned state. At this time, the impact energy can be effectively absorbed. Then the telescopic cylinder 4 rotates a certain angle away from the impact point. At this time, the dial plate 402 can push the water flow towards the impact direction or block the water flow impact generated from the impact point of the fixing belt 2. Since the dial plate 402 swings towards the impact point under the drive of the telescopic cylinder 4, the water flow generated by the swing collides with the water flow generated by the impact, which can further disperse the energy generated by the impact.

[0023] When in use, a pair of fixing cylinders 1 are arranged to move up and down on the bridge pier, and a fixing belt 2 is sleeved on the fixing cylinder 1. Moreover, an anti-collision barrel 301 that can float on the water surface is fixedly arranged on the outer wall of the fixing belt 2. On the one hand, it can automatically adjust the positions of the anti-collision barrel 301 and the fixing sleeve 1 on the bridge pier as the water level changes. On the other hand, when being impacted, the anti-collision barrel 301 and the elastic fixing belt 2 can absorb a certain amount of impact energy. The fixing belt 2 drives the anti-collision barrel 301 to slide a certain distance, which can not only guide the ship to deviate from the bridge pier, reduce the direct impact force, protect both the ship and the bridge pier, but also effectively disperse and absorb the energy, improving the use effect. By fixedly arranging a fixing frame 101 between the fixing cylinders 1, rotatably arranging a telescopic cylinder 4 on the fixing frame 101, slidably arranging tensioning plates 5 for tensioning the fixing belt 2 at both ends of the telescopic cylinder 4, and fixedly arranging dial plates 402 on both sides of the telescopic cylinder 4, on the one hand, the fixing belt 2 can be tensioned to a certain extent, effectively absorbing the impact energy. On the other hand, when being impacted, the telescopic cylinder 4 rotates a certain angle away from the impact point. At this time, the dial plate 402 can push the water flow towards the impact direction or block the water flow impact generated from the impact point of the fixing belt 2. Since the dial plate 402 swings towards the impact point under the drive of the telescopic cylinder 4, the water flow generated by the swing collides with the water flow generated by the impact, which can further disperse the energy generated by the impact.

[0024] Refer to Figures 1 - 4, here, we preferably set two groups of fixing frames 101, which are respectively fixedly arranged at the top and bottom of a pair of fixed cylinders 1, and rotatably arrange the telescopic cylinder 4 between the two groups of fixing frames 101. At this time, the top and bottom of the telescopic cylinder 4 respectively abut against the inner walls of the two groups of fixing frames 101. When in use, by setting two groups of fixing frames 101, not only can the connection strength between a pair of fixed cylinders 1 be ensured, but also the telescopic cylinder 4 can be limited, improving the use effect.

[0025] Refer to Figure 5 , rotating shafts 403 are fixedly arranged at both the top and bottom of the telescopic cylinder 4. Rotating holes corresponding to the rotating shafts 403 are opened on the fixing frame 101, and the rotating shafts 403 are rotatably arranged in the rotating holes. When in use, by fixedly arranging the rotating shafts 403 at both the top and bottom of the telescopic cylinder 4 and rotatably connecting the rotating shafts 403 with the two groups of fixing frames 101 respectively, it can ensure the reliable rotation of the telescopic cylinder 4 and reduce the possibility of falling off from the fixing frame 101, improving the use effect.

[0026] Refer to Figure 5 , a limiting shaft 404 is fixedly arranged at the top of the rotating shaft 403. The limiting shaft 404 coincides with the axis of the rotating shaft 403. A clamping groove is opened on the limiting shaft 404 along its diameter direction. A torsion spring 6 is sleeved on the limiting shaft 404. The diameter of the circle formed by the torsion spring 6 is larger than the diameter of the limiting shaft 404. Clamping portions 601 are fixedly arranged at both ends of the torsion spring 6, and limiting grooves are opened on the inner wall of the rotating hole. The clamping portions 601 are respectively clamped and connected with the clamping groove and the limiting groove. That is to say, torsion springs 6 are arranged at both the top and bottom of the telescopic cylinder 4. At this time, the installation directions of the torsion springs 6 are the same, which can keep the telescopic cylinder 4 in a state where its two side surfaces are perpendicular to the central plane of a pair of fixed cylinders 1. When in use, by fixedly arranging the limiting shaft 404 on the rotating shaft 403, sleeving the torsion spring 6 on the limiting shaft 404, and clamping the two ends of the torsion spring 6 with the clamping groove and the limiting groove respectively, when a ship impacts the fixing belts 2 on both sides of the tensioning plate 5, the telescopic cylinder 4 deflects, and then under the action of the torsion spring 6, after the ship evacuates, it can drive the telescopic cylinder 4 to return to its original position and keep in a state where its two side surfaces are perpendicular to the central plane of a pair of fixed cylinders 1, facilitating the tensioning of the fixing belt 2 and improving the use effect.

[0027] Refer to Figure 4 , a piston cavity 401 is opened in the telescopic cylinder 4. Piston plates 502 are slidably arranged at both ends of the piston cavity 401. Connecting plates 501 are fixedly arranged on the piston plates 502, and one end of the connecting plate 501 extending out of the piston cavity 401 is respectively fixedly connected with the corresponding tensioning plate 5. When in use, by opening the piston cavity 401 in the telescopic cylinder 4, sliding the piston plates 502 in the piston cavity 401, and fixedly connecting the tensioning plate 5 with the piston plate 502 through the connecting plate 501, it can ensure the reliable sliding of the tensioning plate 5 and improve the use effect.

[0028] Refer to Figure 4 , a spring is arranged in the piston cavity 401, and the two ends of the spring are respectively abutted against the opposite surfaces of the two groups of piston plates 502. A transmission medium is filled between the two groups of piston plates 502. The transmission medium can be a gas or a liquid with a certain pressure. Here, we preferably choose hydraulic oil. Moreover, a gasket is fixedly arranged on the piston plate 502, which can improve the sealing effect between the piston plate 502 and the inner wall of the piston cavity 401. During use, by arranging a spring in the piston cavity 401 and filling the piston cavity 401 between the two groups of piston plates 502 with hydraulic oil having a certain pressure, under the action of the spring and the hydraulic oil, not only can the fixing belt 2 be kept in a tensioned state, but also because the compressibility of the hydraulic oil is relatively low and almost incompressible, so when one side of the tensioning plate 5 is impacted, the impact force can be transmitted to the tensioning plate 5 on the other side through the hydraulic oil, causing the tensioning plate 5 on the other side to extend and lift the fixing belt 2, facilitating the fixing belt 2 to absorb and disperse the impact energy and improving the use effect.

[0029] Refer to Figure 6 , the anti-collision barrel 301 includes an inner core and an outer shell. The inner core is honeycomb-shaped, and a collapse groove 302 is opened in the outer shell. The material of the outer shell is preferably plastic, and the material of the anti-collision barrel 301 is preferably high-density polyethylene material. During use, by arranging the outer shell with the collapse groove 302 and the honeycomb-shaped inner core in the anti-collision barrel 301, the energy generated by the impact can be better absorbed, the damage to the bridge pier and the ship can be reduced, and the use effect can be improved.

[0030] Refer to Figures 1 - 4 , a rotation groove 102 is opened on the outer wall of the fixed cylinder 1, and the fixing belt 2 is sleeved in the rotation groove 102. The rotation groove 102 can limit and guide the fixing belt 2 to ensure that the fixing belt 2 slides between a pair of fixed cylinders 1. Moreover, a plurality of guiding grooves 103 distributed along the axis are opened on the inner wall of the fixed cylinder 1. There are two to ten groups of guiding grooves 103. Here, we preferably choose four groups, and the four groups are evenly distributed in a circle. Moreover, a guide rail is fixedly arranged on the bridge pier, and there are also four groups of guide rails. The material of the guide rail is preferably stainless steel. The guiding grooves 103 are respectively slidably connected with the corresponding guide rails. On the one hand, it can ensure that the fixed cylinder 1 rises and falls reliably on the bridge pier under the buoyancy of the anti-collision barrel 301 along with the change of the water level. On the other hand, it can prevent the fixed cylinder 1 from directly rising and falling on the bridge pier, increasing the wear of the bridge pier. Furthermore, a rotating roller is rotatably arranged on the inner wall of the guiding groove 103, and the rotating roller is abutted against both sides of the guide rail to further reduce the friction force and improve the lifting effect. During use, by opening the rotation groove 102 on the outer wall of the fixed cylinder 1, the fixing belt 2 can be guided and limited, facilitating the sliding of the fixing belt 2 between a pair of fixed cylinders. During the impact, the fixing belt 2 drives the anti-collision barrel 301 to slide, which can disperse the impact and improve the use effect.

[0031] A self-floating bridge pile anti-collision method further includes the following steps: Step 1: At least one floating device, which has sufficient buoyancy to support itself and is arranged around the bridge pile. Here, we set the floating device as a fixed cylinder 1 that can move up and down along the bridge pile. A fixed belt 2 is rotatably arranged on the fixed cylinder 1, and an anti-collision barrel 301 that can float on the water surface is fixedly arranged on the outer side of the fixed belt 2. It can follow the change of the water level and adjust the positions of the fixed cylinder 1, the fixed belt 2, and the anti-collision barrel 301 on the bridge pile under the buoyancy of the anti-collision barrel 301. Here, two-thirds of the anti-collision barrel 301 is located below the water surface and one-third is above the water surface. Further, warning patterns are fixedly arranged on the outer wall of the anti-collision barrel 301. Step 2: An energy absorption structure is rotatably arranged outside the floating device to absorb and disperse the energy generated by the impact. Here, the main body of the energy absorption structure is the anti-collision barrel 301, which consists of a shell with a crush groove 302 and a honeycomb-shaped inner core, and can absorb the energy generated by the impact. The anti-collision barrel 301 is fixed on the fixed belt 2, and the fixed belt 2 is rotatably connected to the fixed cylinder 1. When being impacted, the anti-collision barrel 301 and the fixed belt 2 can rotate to a certain extent, effectively dispersing and absorbing the energy, further guiding the ship to deviate from the bridge pier and reducing the direct impact force. Step 3: An elastic structure is arranged between the floating devices. The elastic structure is a telescopic cylinder 4. Through a tensioning plate 5 on the telescopic cylinder 4, the fixed belt 2 can be tensioned, enabling the fixed belt 2 to have the effect of absorbing the impact energy.

[0032] As mentioned above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
