Description

Technical Field

[0001] This invention belongs to the field of bridge pier protection technology, and particularly relates to an O-type cell sandwich structure protection device with stress relief function. Background Technology

[0002] With the rapid development of modern water transportation, the number, size and speed of navigable ships are constantly increasing. Accidents of ships veering off course and colliding with the piers of bridges across rivers and seas occur frequently. As a key load-bearing component of a bridge, if the piers are subjected to a violent impact, it will not only cause serious damage to the bridge structure or even lead to the collapse of the bridge, but also bring huge losses of life and property and adverse social impacts. Therefore, anti-collision devices are usually used for protection.

[0003] Existing buffer structures, when subjected to ship impacts, often only experience localized and severe deformation at the directly impacted area. Due to the lack of effective linkage and tension mechanisms between the internal buffer units, the enormous stress at the moment of impact cannot be channeled and dispersed to the surrounding non-contact areas, which can easily lead to localized stress concentration and material tearing or damage. The overall impact resistance of the structure is greatly reduced. Furthermore, traditional solid buffer pads become harder as they are compressed during impacts, resulting in an increase in material stiffness at the end of the impact, which can damage the bridge piers. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the stiffness of traditional solid cushioning pads increases at the end of the impact, and to propose an O-type cell sandwich structure protective device with stress-dissipating function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an O-type cell sandwich structure protection device with stress-dissipating function, comprising a bridge pier, wherein an installation sleeve is installed on the outer wall of the bridge pier, and the outer wall of the installation sleeve is provided with toothed grooves, and further comprising:

[0006] A buffer assembly, comprising a buffer ring sleeved on the outside of the mounting sleeve, wherein multiple buffer rings are evenly arranged to reduce the impact force when subjected to a collision. The protective component includes rollers disposed outside the buffer ring, and multiple rollers are arranged circumferentially. The floating assembly includes fixed teeth disposed on the outside of the mounting sleeve, and the fixed teeth mesh with tooth grooves to limit the upper and lower positions of the buffer ring through the meshing between the fixed teeth and tooth grooves.

[0007] As a further description of the above technical solution: The buffer assembly further includes: connecting strips, which are disposed between the buffer rings, and multiple connecting strips are provided to increase the connection between the buffer rings; The skin is fitted onto the outer wall of the buffer ring.

[0008] As a further description of the above technical solution: The buffer assembly further includes an elastic ring, which is mounted on one side of the skin and located inside the circumference of the buffer ring. A connecting plate is installed inside the circumference of the buffer ring, and multiple connecting plates are arranged around the circumference. One side of the connecting plate is provided with a groove corresponding to the buffer ring.

[0009] As a further description of the above technical solution: The buffer assembly further includes: a mounting base, which is installed on the outer wall of the elastic ring and corresponds to the connecting plate, and multiple mounting bases are arranged circumferentially; A slider is installed on one side of the connecting plate, and multiple sliders are evenly arranged. A sliding groove is formed on the surface of the mounting base, and the slide bar is slidably connected to the sliding groove. The sliding range of the slide bar is controlled by the sliding groove.

[0010] As a further description of the above technical solution: The floating assembly further includes: a mounting ring, which is sleeved on the outer wall of the mounting sleeve, and the outer wall of the mounting ring is in contact with the elastic ring, and the fixing teeth are slidably connected to the mounting ring through the internal through hole of the mounting ring; The connecting groove is formed inside the mounting ring, and multiple connecting grooves are arranged circumferentially.

[0011] As a further description of the above technical solution: The floating component further includes: a flap, which is slidably disposed in a groove on the outer wall of the mounting ring, and multiple flaps are arranged circumferentially, with one end of the flap corresponding to a fixed tooth. The fixed tooth is limited by the flap pressing against it. The connecting column is installed at both the upper and lower ends of the flap plate and is slidably disposed inside the connecting groove.

[0012] As a further description of the above technical solution: The floating assembly further includes: a top rod, which is slidably disposed in the insertion hole inside the mounting ring, and one end of the top rod abuts against the flap, and multiple top rods are evenly arranged; A first spring is installed at the other end of the top rod, and the other end of the first spring is fixedly connected to the mounting ring. The top rod is pushed by the first spring to provide elastic support for the flap.

[0013] As a further description of the above technical solution: The protective assembly further includes: a mounting plate, which is installed on the upper and lower sides of the skin, and the inner side of the mounting plate is fixedly connected to the mounting ring; The support rod is slidably installed in a groove inside the mounting plate, and the rollers are rotatably connected to the support rod through the internal through hole of the support rod, and multiple rollers are arranged circumferentially on the support rod.

[0014] As a further description of the above technical solution: The protective component also includes: a slot, which is formed on both sides of the support rod; The retaining strip is installed on the inner wall of the groove in the mounting plate and is slidably connected to the groove. The connection between the retaining strip and the groove is used to limit the position of the support rod.

[0015] As a further description of the above technical solution: The protective assembly further includes: a fixing rod, which is slidably disposed in the through hole inside the support rod, and one end of the fixing rod is fixedly connected to the mounting plate; The second spring is installed at the other end of the fixed rod and is located inside the support rod, and is fixedly connected to the support rod.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, by setting up a buffer component, a buffer ring can be used to protect the outside of the bridge pier when it is being protected. Since the buffer ring has an O-shaped cross-section, it can deform when it is impacted to buffer the impact. Furthermore, the buffer ring around the impact area can be stretched by the connecting strip to deform it, thereby further ensuring the safety of the bridge pier. When the buffer ring is impacted, it can drive the connecting plate to rotate, thereby changing the direction of the impact force and reducing the impact force.

[0017] 2. In this invention, by setting up a floating component, the buffer ring can float up and down during the protection process to ensure that it is on the water surface. When the buffer ring is impacted, the contraction of the buffer ring can squeeze the flap, which in turn squeezes the fixed teeth, thereby making the fixed teeth and the tooth groove tightly meshed. This prevents the buffer ring from moving up and down after being impacted, thus ensuring that it can effectively protect the bridge pier and further guarantee the safety of the bridge pier.

[0018] 3. In this invention, by setting up protective components, when ships or other objects collide with the buffer ring, rollers can be used to isolate the buffer ring from the ship. At the same time, since the rollers can rotate, the rotation of the rollers can be used to guide the ship to change its direction of impact, thereby preventing the ship from colliding directly with the bridge pier and protecting the bridge pier. Furthermore, the ship's turning can reduce the impact force on the buffer ring, thus further protecting the bridge pier. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-9 The present invention provides a technical solution: an O-type cell sandwich structure protection device with stress-dissipating function, including a bridge pier 1, an installation sleeve 2 installed on the outer wall of the bridge pier 1, and a toothed groove 3 formed on the outer wall of the installation sleeve 2, and further including: The buffer assembly 6 includes a buffer ring 602 sleeved on the outside of the mounting sleeve 2, and multiple buffer rings 602 are evenly arranged to reduce the impact force when subjected to a collision. The protective component 5 includes rollers 502 disposed on the outside of the buffer ring 602, and multiple rollers 502 are arranged circumferentially. The floating component 4 includes a fixing tooth 401 disposed on the outside of the mounting sleeve 2, and the fixing tooth 401 meshes with the tooth groove 3. The meshing between the fixing tooth 401 and the tooth groove 3 is used to limit the upper and lower positions of the buffer ring 602. like Figure 3 , Figure 4 As shown, the buffer assembly 6 also includes: a connecting strip 603 and a skin 601; Connecting strips 603 are disposed between buffer rings 602, and multiple connecting strips 603 are provided. The connecting strips 603 are used to increase the connection between buffer rings 602. Skin 601 is sleeved on the outer wall of buffer ring 602. The buffer assembly 6 also includes: an elastic ring 606 and a connecting plate 604; The elastic ring 606 is installed on one side of the skin 601 and is located inside the circumference of the buffer ring 602. The connecting plate 604 is installed inside the circumference of the buffer ring 602 and multiple connecting plates 604 are arranged around the circumference. A groove corresponding to the buffer ring 602 is provided on one side of the connecting plate 604. The buffer assembly 6 also includes: a mounting base 605, a slide bar 607, and a slide groove 608; Mounting base 605 is installed on the outer wall of elastic ring 606, and mounting base 605 corresponds to connecting plate 604. Multiple mounting bases 605 are arranged circumferentially. Slide bars 607 are installed on one side of connecting plate 604, and multiple slide bars 607 are evenly arranged. Slide groove 608 is formed on the surface of mounting base 605, and slide bars 607 are slidably connected to slide groove 608. The sliding range of slide bars 607 is controlled by slide groove 608.

[0031] Specifically: During the process of protecting the pier 1 through the buffer ring 602, when ships or other objects approach the pier 1, they will first come into contact with the buffer ring 602 inside the skin 601, causing the buffer ring 602 to deform after being impacted. This deformation releases the stress during the impact, thereby reducing the impact force and protecting the pier 1. Furthermore, during the deformation of the buffer ring 602 at the impact site, the connecting strip 603 can be used to pull the surrounding buffer rings 602, so that the surrounding buffer rings 602 deform accordingly, thereby further reducing the impact force. Also, since the connecting strip 603 itself is also made of elastic material, it can prevent the buffer rings 602 from being directly pulled together, thus avoiding damage to the buffer rings 602. Furthermore, when the buffer ring 602 is deformed by impact, the buffer ring 602 can drive the connecting plate 604 to move, and cause the slide bar 607 to slide inside the slide groove 608, so as to change the direction of the impact force by rotating the buffer ring 602, so as to further ensure the safety of the pier 1.

[0032] like Figure 8 , Figure 9 As shown, the floating assembly 4 also includes: a mounting ring 402 and a connecting groove 407; The mounting ring 402 is sleeved on the outer wall of the mounting sleeve 2, and the outer wall of the mounting ring 402 fits against the elastic ring 606. The fixing tooth 401 is slidably connected to the mounting ring 402 through the internal through hole of the mounting ring 402. The connecting groove 407 is opened inside the mounting ring 402, and multiple connecting grooves 407 are arranged circumferentially. The floating component 4 also includes: a flap 406 and a connecting column 405; The flap 406 is slidably disposed in the groove on the outer wall of the mounting ring 402, and multiple flaps 406 are arranged circumferentially. One end of the flap 406 corresponds to the fixing tooth 401. The fixing tooth 401 is limited by the pressing of the flap 406 against the fixing tooth 401. The connecting post 405 is installed at the upper and lower ends of the flap 406, and the connecting post 405 is slidably disposed inside the connecting groove 407. The floating assembly 4 also includes: a push rod 404 and a first spring 403; The push rod 404 is slidably disposed in the insertion hole inside the mounting ring 402, and one end of the push rod 404 abuts against the flap 406. Multiple push rods 404 are evenly arranged. The first spring 403 is installed at the other end of the push rod 404, and the other end of the first spring 403 is fixedly connected to the mounting ring 402. The push rod 404 is pushed by the first spring 403 to provide elastic support for the flap 406.

[0033] Specifically: During the process of the buffer ring 602 protecting the pier 1, since the buffer ring 602 itself can float on the water surface, the buffer ring 602 can float up and down under the influence of the waves, and drive the installation ring 402 to float up and down, so as to ensure that the buffer ring 602 is always on the water surface. Furthermore, during the up-and-down floating process of the mounting ring 402, although the fixed tooth 401 meshes with the tooth groove 3, the flap 406 does not squeeze the fixed tooth 401 under the action of the first spring 403 and the push rod 404. Also, since the tooth sides of both the fixed tooth 401 and the tooth groove 3 are inclined, the fixed tooth 401 can move into the mounting ring 402 under the squeezing of the tooth groove 3 during the up-and-down floating process of the mounting ring 402, so as to ensure that the mounting ring 402 can float up and down. Furthermore, when the buffer ring 602 is impacted, the buffer ring 602 is squeezed inward, which in turn drives the elastic ring 606 to squeeze inward, so that the flap 406 moves inward to squeeze the fixed tooth 401, thereby making the fixed tooth 401 tightly engaged with the tooth groove 3. Under the action of the flap 406, the fixed tooth 401 is prevented from retracting, thus preventing the buffer ring 602 from floating up and down when impacted and failing to provide effective protection. Furthermore, after the vessel or other objects separate from the buffer ring 602, the first spring 403 can cause the flap 406 to separate from the fixed tooth 401 again, so that the flap 406 no longer squeezes the fixed tooth 401, thereby allowing the fixed tooth 401 to retract back into the mounting ring 402, thus ensuring that the mounting ring 402 can float up and down again.

[0034] like Figures 5-7 As shown, the protective assembly 5 also includes: a mounting plate 504 and a support rod 501; Mounting plate 504 is installed on the upper and lower sides of skin 601, and the inner side of mounting plate 504 is fixedly connected to mounting ring 402. Support rod 501 is slidably installed in the groove inside mounting plate 504, and roller 502 is rotatably connected to support rod 501 through the internal through hole of support rod 501. Multiple support rods 501 are arranged circumferentially. Protective component 5 also includes: a card slot 503 and a card strip 507; The slots 503 are formed on both sides of the support rod 501, and the clips 507 are installed on the inner wall of the groove of the mounting plate 504. The clips 507 are slidably connected to the slots 503. The connection between the clips 507 and the slots 503 is used to limit the position of the support rod 501. The protective component 5 also includes: a fixing rod 505 and a second spring 506; The fixing rod 505 is slidably disposed in the through hole inside the support rod 501, and one end of the fixing rod 505 is fixedly connected to the mounting plate 504. The second spring 506 is installed at the other end of the fixing rod 505, and the second spring 506 is located inside the support rod 501 and is fixedly connected to the support rod 501.

[0035] Specifically: When the buffer ring 602 is impacted, since the roller 502 is located on the outer wall of the buffer ring 602, it will come into contact with the roller 502 during the impact process, and the rotation of the roller 502 will change the direction of the ship, thereby changing the impact direction and reducing the impact force on the buffer ring 602. Furthermore, when the roller 502 is compressed, it can slide and compress the second spring 506, thereby reducing the impact force. Under the action of the locking strip 507 and the locking groove 503, the support rod 501 can be limited to ensure the smooth movement of the roller 502.

[0036] Working principle: When the waves rise and fall daily, the buoyancy of the buffer ring 602 causes the mounting ring 402 to float up and down along the mounting sleeve 2 outside the pier 1. At this time, since the first spring 403 supports the flap 406 through the top rod 404, the fixing tooth 401 is not squeezed and can freely retract in the inclined tooth groove 3 to adapt to the water level change. Furthermore, when encountering a ship collision, the outermost protective component 5 takes effect first. The roller 502 changes the direction of the ship by rotating to deflect the impact force, and is squeezed to drive the support rod 501 to slide smoothly inward along the locking strip 507 and the locking groove 503, using the compression of the second spring 506 to initially absorb the impact. Furthermore, as the impact force is transmitted inward, the buffer ring 602 at the impact location inside the skin 601 deforms, and the elastic connecting strip 603 pulls the surrounding buffer rings 602 to produce coordinated deformation, thereby dispersing and releasing stress over a large area. At the same time, the deformation of the buffer ring 602 causes the slide strip 607 on the connecting plate 604 to slide in the slide groove 608 of the mounting base 605, and the rotation further mitigates the impact direction. Furthermore, at the moment when the buffer ring 602 is pressed inward by the impact, the elastic ring 606 will push the flap 406 of the floating component 4, causing the flap 406 to abut against the fixing tooth 401, forcing the fixing tooth 401 to tightly mesh with the tooth groove 3 on the mounting sleeve 2, so as to prevent the device from floating up and down when it is impacted, thus causing the protection to fail. Furthermore, after the impact ends and the vessel departs, the first spring 403 pushes open the flap 406 again, releasing the restriction on the fixed tooth 401. The fixed tooth 401 regains its retraction ability, and the entire protective device automatically unlocks and returns to its normal up-and-down floating state.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
