Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of bridge protection devices, and in particular relates to a bridge pier flood and collision prevention device. Background Art
[0002] my country's monsoon climate is significant, and flooding is common in summer. During flood seasons, bridge structures must ensure the passage of rescue vehicles and large transport vehicles carrying specialized equipment. To ensure the safe passage of these specialized vehicles and the normal operation of bridge structures along the route, flood control measures must be implemented on the bridge substructure.
[0003] Existing flood prevention methods typically involve wrapping bridge piers with cushioning material and allowing it to rotate around the piers. The purpose of this rotation is to change the direction of movement of the impacting object. However, this method has the following disadvantages: when the impacting object strikes the surface of the cushioning material perpendicularly, the cushioning material cannot rotate. Although the impact force is buffered and dissipated, a large torque is still transmitted to the bridge pier, which may cause damage to the pier. Summary of the Invention
[0004] In view of this, the purpose of the present invention is to provide a bridge pier flood prevention and anti-collision device to solve the problem that the bridge pier anti-collision device in the prior art does not provide comprehensive anti-collision protection for the bridge pier, resulting in damage to the bridge pier due to impact.
[0005] In order to achieve the above object, the present invention provides the following technical solutions:
[0006] The present invention provides a bridge pier flood prevention and anti-collision device, which is arranged on the bridge pier and includes an annular inner ring, an annular outer ring, a plurality of rollers, and a plurality of arc-shaped spring pieces. The annular inner ring is sleeved on the bridge pier, the annular outer ring is sleeved on the annular inner ring, a plurality of rollers are evenly distributed between the annular inner ring and the annular outer ring, one end of the plurality of arc-shaped spring pieces is evenly distributed on the annular outer ring, and the other end of the plurality of arc-shaped spring pieces covers the end of the adjacent arc-shaped spring piece connected to the annular outer ring, a first buffer spring is provided between adjacent arc-shaped spring pieces, one end of the first buffer spring is fixedly connected to the outer surface of the inner arc-shaped spring piece, and the other end of the first buffer spring is provided on the inner side surface of the outer arc-shaped spring piece.
[0007] The working principle of this technical solution is:
[0008] During the flood season, when one of the arc-shaped spring pieces is hit, the arc-shaped spring piece itself will first deform to consume energy, and then contact the first buffer spring, the first buffer spring will be compressed to consume energy twice, and the first buffer spring will transfer the impact force to the adjacent arc-shaped spring piece, consuming energy three times, and so on. That is, the device has the functions of dispersing energy, consuming energy and changing the direction of energy transfer, thereby improving the energy consumption effect of the impact. At the same time, the first buffer spring can also support the arc-shaped spring piece; the arc-shaped spring piece is set in a covering manner, which can isolate and cover the connection between the arc-shaped spring piece and the bridge pier, that is, it is difficult for the impact object to apply the impact force vertically to the bridge pier, thereby improving the protection effect of the bridge pier.
[0009] Furthermore, an electric telescopic element is provided between the electric hinge and the annular outer ring and is arranged perpendicular to the annular inner ring. A control system electrically connected to the electric telescopic element is provided on the pier, and the electric telescopic element is electrically connected to the control system.
[0010] Furthermore, the electric telescopic element includes a telescopic shell arranged in the middle, and a first connecting column and a second connecting column are respectively provided at both ends of the telescopic shell, which are slidably connected thereto, and one end of the outside of the first connecting column and the second connecting column is fixedly connected to the annular outer ring and the electric hinge respectively, and one end of the first connecting column and the second connecting column arranged inside the telescopic shell is respectively fixed to the two ends of the second buffer spring, and an electric hydraulic element is provided inside the telescopic shell, and the two ends of the electric hydraulic element are respectively fixed on the inner side surfaces of the two ends of the telescopic shell, and the electric hydraulic element is electrically connected to the control system.
[0011] It is not difficult to understand that the initial position of the electric telescopic element is that the second buffer spring is in a naturally extended state. At this time, the stiffness of the second buffer spring is small, that is, the energy consumption effect at small displacement is relatively small. When the electric hydraulic element controls the retraction of the telescopic shell, the second buffer spring is compressed, and the stiffness becomes larger, that is, the energy consumption effect of the second buffer spring is enhanced. That is, the energy consumption effect of the second buffer spring can be adjusted according to actual conditions, and it is suitable for the energy consumption requirements of various bridge piers. At the same time, the setting of the electric telescopic element can adjust the distance between the arc-shaped spring and the bridge pier, which can be applied to rivers of different widths and has strong versatility.
[0012] Furthermore, an electric hinge is provided at the connection point between the arc-shaped spring piece and the second connecting column, the outer shell of the electric hinge is fixed on the second connecting column, the movable end of the electric hinge is fixed on the arc-shaped spring piece, and a pressure probe is provided on the outer surface of the arc-shaped spring piece, and the pressure probe is electrically connected to the control system.
[0013] The device is installed on a bridge pier. The pressure probe senses the pressure of the water flow and transmits data such as the size and direction of the pressure to the control system. The control system controls the rotation of the electric hinge according to the direction and pressure of the water flow, that is, drives the arc-shaped spring pieces to rotate, thereby controlling the spacing between adjacent arc-shaped spring pieces and the contact angle between the arc-shaped spring pieces and the direction of the water flow (during the flood season, when the arc-shaped spring pieces are subjected to a large impact force, the spacing between the arc-shaped spring pieces is small, and multiple adjacent arc-shaped spring pieces will deform and contact, causing multiple arc-shaped spring pieces to deform together and achieve the effect of common energy consumption. During the non-flood season, when the impact force on the arc-shaped spring pieces is small and the spacing is large, the effect of multiple arc-shaped spring pieces rotating under the action of the water flow is good. The rotation is not only for power generation operation, but also for changing the direction of movement of the impacting object. The angle adjustment between the arc-shaped spring pieces and the direction of the water flow can enhance the guiding and force-relieving effect of the arc-shaped spring pieces on the object when the object hits the arc-shaped spring pieces. Of course, the specific angle size can be obtained based on a limited number of experiments. I will not go into too much detail here).
[0014] Furthermore, a power generation mechanism is provided on the annular inner ring and the annular outer ring, and the power generation mechanism includes at least one micro-generator, a battery, a transmission ring, a rotating column and a mounting plate. The transmission ring is fixed to the upper end of the annular outer ring, the mounting plate is provided on the upper end of the annular inner ring, the micro-generator is fixed to the mounting plate, the rotating column is fixed to the rotating end of the micro-generator, the outer side surface of the rotating column is in close contact with the outer side surface of the transmission ring, and the micro-generator is electrically connected to the battery.
[0015] The impact of water flow on the arc-shaped spring piece will drive the outer ring to rotate, which in turn drives the transmission ring to rotate. The friction between the transmission ring and the rotating column drives the rotating column to rotate. The rotation of the rotating column can drive the micro-generator to rotate, thereby enabling power generation, facilitating the use of electrical components in the device, and also providing power for street lights on bridges.
[0016] Furthermore, the arc-shaped spring piece is a spring steel sheet.
[0017] Furthermore, a float fixedly connected to the end of the annular outer ring facing the water surface is provided, and the middle part of the float is slidably connected to the bridge pier. The benefit is that the arrangement of the float facilitates the device to adapt to changes in water level.
[0018] Furthermore, an elastic cloth is provided on one end of the arc-shaped spring piece that is arranged outward, one end of the elastic cloth is fixed on the end of the arc-shaped spring piece, and the other end is fixed on the outer surface of the adjacent arc-shaped spring piece. The benefit of this is that it solves the problem of floating objects entering between adjacent arc-shaped spring pieces and affecting the deformation and energy consumption of the arc-shaped spring pieces.
[0019] The beneficial effects of the present invention are:
[0020] (1) The end covering setting of adjacent arc-shaped spring pieces and the setting mode of one end of the arc-shaped spring piece and the outer ring change and disperse the direction of the impact force of the impact object, that is, the impact force is difficult to be directly transmitted to the bridge pier, thereby improving the protection effect of the bridge pier; (2) The arc-shaped spring piece can be rotated, that is, when the impact object hits, the device will rotate, which can change the movement direction of the impact object, further improving the protection effect of the bridge pier; (3) When the impact object and the arc-shaped spring piece come into contact, the arc-shaped spring will deform, and the deformation of the arc-shaped spring piece will change the movement direction of the impact object, thereby affecting the movement of the impact object. The device can be guided to quickly separate the impacting object from the bridge pier, thereby further improving the protection effect of the bridge pier (the advantage of the end cover setting is that the impacting object cannot directly contact the end where the arc-shaped spring piece is connected to the bridge pier, which avoids the vertical transmission of the impact force to the bridge pier); (4) When the device rotates, it can also generate electricity to meet the power demand of the device; (5) The setting of the electric hinge and the electric telescopic element in the device makes the angle of the arc-shaped spring piece of the device rotatable and the length of the arc-shaped spring piece extended can be controlled, which can be applied to bridge piers with different water flow directions and energy consumption requirements.
[0021] Other advantages, objectives and features of the present invention will be described in the following description and will be apparent to those skilled in the art to some extent, or those skilled in the art can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0032] like Figures 1 to 7 As shown, a bridge pier flood prevention and anti-collision device of the present invention is arranged on the bridge pier 1, including an annular inner ring 2, an annular outer ring 3, a plurality of rollers 4, and a plurality of arc-shaped spring pieces 12. The annular inner ring 2 is sleeved on the bridge pier 1, the annular outer ring 3 is sleeved on the annular inner ring 2, and the plurality of rollers 4 are evenly distributed between the annular inner ring 2 and the annular outer ring 3. One ends of the plurality of arc-shaped spring pieces 12 are evenly distributed on the annular outer ring 3, and the other ends of the plurality of arc-shaped spring pieces 12 cover the ends of the adjacent arc-shaped spring pieces 12 connected to the annular outer ring 3. A first buffer spring 11 is provided between adjacent arc-shaped spring pieces 12, one end of the first buffer spring 11 is fixedly connected to the outer surface of the inner arc-shaped spring piece 12, and the other end of the first buffer spring 11 is provided on the outside of the inner side surface of the outer arc-shaped spring piece 12.
[0033] The working principle of this technical solution is:
[0034] During the flood season, when one of the arc-shaped spring pieces 12 is hit, the arc-shaped spring piece 12 itself will first deform to consume energy, and then contact the first buffer spring 11. The first buffer spring 11 is compressed to consume energy twice. The first buffer spring 11 transfers the impact force to the adjacent arc-shaped spring piece 12, consuming energy three times, and so on. That is, the device has the functions of dispersing energy, consuming energy and changing the direction of energy transfer, thereby improving the energy consumption effect of the impact. At the same time, the first buffer spring 11 can also support the arc-shaped spring piece 12; the arc-shaped spring piece 12 is arranged in a covering manner, which can isolate and cover the connection between the arc-shaped spring piece 12 and the bridge pier 1, that is, it is difficult for the impact object to apply the impact force vertically to the bridge pier 1, thereby improving the protection effect of the bridge pier 1.
[0035] An electric telescopic element 9, disposed perpendicularly to the annular inner ring 2, is disposed between the electric hinge 10 and the annular outer ring 3. The electric telescopic element 9 is electrically connected to the control system 17. Specifically, the electric telescopic element 9 includes a centrally disposed telescopic housing 91. A first connecting post 93 and a second connecting post 92 are slidably connected to the housing 91 at either end. The outer ends of the first and second connecting posts 93 and 92 are fixedly connected to the annular outer ring 3 and the electric hinge 10, respectively. The first and second connecting posts 93 and 92 are disposed within the telescopic housing and are fixed to the ends of a second buffer spring 95. An electric hydraulic element 94 is disposed within the telescopic housing. The ends of the electric hydraulic element 94 are fixed to the inner side surfaces of the housing. The electric hydraulic element 94 is electrically connected to the control system 17 via a wire 18. The control system can be fabricated and configured using components such as a single-chip microcomputer, and the prior art will not be elaborated upon here.
[0036] It is not difficult to understand that the initial position of the electric telescopic element 9 is that the second buffer spring 95 is in a naturally extended state. At this time, the stiffness of the second buffer spring 95 is small, that is, the energy consumption effect at small displacement is relatively small. When the electric hydraulic element 94 controls the retraction of the telescopic shell 91, the second buffer spring 95 is compressed, and the stiffness becomes larger, that is, the energy consumption effect of the second buffer spring 95 is enhanced. That is, the energy consumption effect of the second buffer spring 95 can be adjusted according to actual conditions, and is suitable for the energy consumption requirements of various bridge piers 1. At the same time, the setting of the electric telescopic element 9 can adjust the distance between the arc-shaped spring 12 and the bridge pier 1, which can be applicable to rivers of different widths, and has strong versatility. The electric hydraulic element 94 is preferably an electric hydraulic push rod.
[0037] An electric hinge 10 is provided at the connection between the curved spring piece 12 and the second connecting column 92. The outer shell of the electric hinge 10 is fixed to the second connecting column 92, and the movable end of the electric hinge 10 is fixed to the curved spring piece 12. A pressure probe 13 is provided on the outer surface of the curved spring piece 12. A control system 17 electrically connected to the pressure probe 13 and the electric hinge 10 is provided on the bridge pier 1. The electric hinge 10 can be understood as a component at the connection between the door and the door frame that can automatically open and close. It is a prior art and will not be described in detail here.
[0038] The device is installed on the bridge pier 1. The pressure probe 13 senses the pressure of the water flow and transmits data such as the size and direction of the pressure to the control system 17. The control system 17 controls the rotation of the electric hinge 10 according to the direction and pressure of the water flow, that is, drives the arc-shaped spring pieces 12 to rotate, thereby controlling the spacing between adjacent arc-shaped spring pieces 12 and the contact angle between the arc-shaped spring pieces 12 and the direction of the water flow (during the flood season, when the arc-shaped spring pieces 12 are subjected to a large impact force, the spacing between the arc-shaped spring pieces 12 is small, and the adjacent multiple arc-shaped spring pieces 12 will be deformed and contacted). , so that multiple arc-shaped spring pieces 12 are deformed by force together, achieving the effect of common energy consumption. During the non-flood season, the impact force on the arc-shaped spring pieces 12 is small and the spacing is large, so the multiple arc-shaped spring pieces 12 rotate under the action of the water flow for a better effect. The rotation is not only for power generation operation, but also for changing the direction of movement of the impacting object; the angle adjustment between the arc-shaped spring pieces 12 and the water flow direction can enhance the guiding and force-relieving effect of the arc-shaped spring pieces 12 on the object when the object hits the arc-shaped spring pieces 12. Of course, the specific angle size can be obtained based on a limited number of experiments. I will not go into too much detail here).
[0039] The annular inner ring 2 and the annular outer ring 3 are also provided with a power generation mechanism, which includes at least one micro-generator 7, a battery 16, a transmission ring 6, a rotating column 8 and a mounting plate 5. The transmission ring is fixed to the upper end of the annular outer ring 3, the mounting plate 5 is provided on the upper end of the annular inner ring 2, the micro-generator 7 is fixed to the mounting plate 5, the rotating column 8 is fixed to the rotating end of the micro-generator 7, the outer side of the rotating column 8 is in close contact with the outer side of the transmission ring 6, and the micro-generator 7 is electrically connected to the battery 16.
[0040] The impact of water on the curved spring piece 12 causes the outer ring 3 to rotate, which in turn causes the transmission ring 6 to rotate. The friction between the transmission ring 6 and the rotating column 8 drives the rotating column 8 to rotate. The rotation of the rotating column 8 drives the micro-generator 7 to generate electricity, facilitating the use of the electrical components in the device and also providing power for bridge streetlights. The curved spring piece 12 is made of spring steel because it has excellent elastic energy dissipation properties.
[0041] A float 15 is fixedly connected to the end of the annular outer ring 3 facing the water surface. The middle portion of the float 15 is slidably connected to the bridge pier 1. The arrangement of the float 15 allows the device to adapt to changes in the water level. An elastic cloth 14 is attached to the outward end of the curved spring piece 12. One end of the elastic cloth 14 is fixed to the end of the curved spring piece 12, and the other end is fixed to the outer surface of the adjacent curved spring piece 12. This makes it easier for objects in the water to enter between adjacent curved spring pieces 12, which would otherwise affect the deformation and energy dissipation function of the curved spring piece 12.
[0042] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
