Description
Technical Field
The utility model belongs to the technical field of the structure protection, concretely relates to many core pipe anticollision capsule.
Background
In recent years, with the increasing number of ships sailing on rivers and the increasing tonnage, the accident that the ship impacts the pier happens occasionally. The collision of the ship and the bridge often causes the disastrous consequences of the damage of the ship and the bridge structure, the leakage of goods, the environmental pollution, the casualties and the like. Therefore, on a bridge pier, safety measures or protection devices are often provided to ensure the stability and safety of the structure under the impact of the ship.
At present, common pier protection devices can be divided into two major types, namely direct structures and indirect structures. Wherein, direct structure means that protector direct structure is on the pier of being protected, and after hitting the percussion, the impact passes through protector direct action on the pier of being protected. And the indirect structure means that the protective device is not directly connected with the protected bridge, and the impact force does not directly act on the protected bridge. Although both types of protection devices can achieve structural protection to some extent, they have certain drawbacks.
For example, in the case of an indirectly structured protector, the impact force generated when the protector is set and then collided can be absorbed by the protector, and the protector does not act on a bridge pier to be protected, thereby having a strong protective effect on the bridge pier. However, the indirectly constructed guard device is often spaced apart from the pier to be protected, so that it occupies a river or a water area, and the amount of maintenance work is often large. In contrast, the directly constructed protector is generally directly constructed on a pier to be protected, and is mainly classified into three types, i.e., an elastic deformation type, a crush (plastic) deformation type, and a displacement type. After the elastic deformation type protection device is impacted, elastic recovery can be achieved, maintenance work is small, but only small impact with small energy can be applied, and once the impact exceeds the elastic deformation range, the bridge pier is directly impacted, and major accidents are caused. Although the crush deformation type protection device and the displacement type protection device can absorb huge impact energy through plastic deformation and displacement of the device, the maintenance and repair workload of the device after each impact is large, and the application cost of the protection device is high.
In view of the above, the applicant proposed the prior patent application CN201910731622.4, in which a hydraulic anti-collision capsule is specifically disclosed, and by utilizing the corresponding arrangement of each component in the anti-collision capsule and the combined operation of each component when being impacted, the impact protection of the bridge pier is effectively realized, and the service life of the bridge pier structure is prolonged.

referring to fig. 1, the multi-core tube anti-collision capsule in the preferred embodiment of the present invention includes a "capsule-shaped" casing 1, a cavity structure is formed inside the casing 1, and a "strip-shaped" core tube 2 is filled in the casing, so that when the anti-collision capsule is impacted, the impact force can be absorbed and released through elastic deformation of the casing 1 and the core tube 2.
In particular, in the preferred embodiment, the housing 1 is preferably of a "three-section" design, comprising a first housing 101 at the top, a second housing 102 in the middle and a third housing 103 at the bottom, wherein in actual operation, the first housing 101 is arranged to protrude from the water surface and the third housing 103 is partially or completely immersed in the water. Meanwhile, the first shell 101 in the preferred embodiment is hemispherical, and the second shell 102 is cylindrical with two open ends, i.e. the top of the second shell 102 is sealed by the first shell 101; accordingly, the third shell 103 has a special-shaped structure or a frustum-shaped structure due to the bottom closing-in.
It can be understood that, in actual arrangement, the first casing 101, the second casing 102 and the third casing 103 are integrally formed, so as to ensure the integrity and the sealing performance of the casings. Meanwhile, the housing 1 in the preferred embodiment has a multi-layer structure in the thickness direction, and includes a rubber layer, a ply layer, and a leakage-proof layer, which are sequentially arranged from the outside to the inside. Compared with a capsule body prepared from a single rubber layer, the strength of the shell 1 can be fully enhanced through the arrangement of the cord fabric layer, and the sealing performance inside and outside the shell 1 can be effectively improved through the arrangement of the anti-leakage layer. Preferably, an openable and closable exhaust nozzle 104 is provided on the top of the first casing 101, the exhaust nozzle 104 can be closed from the outside of the casing 1, and when opened, communication between the inside and outside spaces of the casing 1 is realized for water drainage and air exhaust.
As shown in fig. 1, the casing 1 in the preferred embodiment encloses a plurality of core tubes 2 (the core tube 2 on the left in fig. 1 is not shown) made of a rubber material, the axes of the core tubes 2 being parallel to each other and preferably to the axis of the casing 1, as shown in fig. 1, i.e., when the casing 1 is vertically arranged, the core tubes 2 are vertically arranged, respectively. Meanwhile, the inner cavity of the shell 1 in the preferred embodiment is fully extruded by a plurality of core tubes 2 which are arranged closely in sequence, thereby ensuring that the shell 1 is tightly supported in a capsule form. Secondly, the core tube 2 in the preferred embodiment is a circular tube structure with two closed ends, a tubular cavity for containing gas is formed inside the core tube, two ends of the core tube can be further preferably arranged to be hemispherical, and an inflating nozzle (not shown in the figure) is arranged at the end part of the core tube, so that the inflation and deflation process in the inner cavity of the core tube 2 is realized.
It is understood that the length, outer diameter, etc. of the core tube 2 in the preferred embodiment can be adjusted accordingly according to the size of the housing 1. In a preferred embodiment, the ratio of the outer diameter of the core tube 2 to the inner diameter of the casing 1 (based on the inner diameter of the second casing 102) is in the range of 0.1 to 0.2, for example in the preferred embodiment as shown in FIG. 2, the outer diameter of the core tube 2 is equal to 1/8 of the inner diameter of the casing 1. In addition, the core tubes 2 of the preferred embodiment are fitted to each other only in a snug manner and are not connected to each other.
In actual installation, the length of the core tube 2 is smaller than that of the shell 1, and the inside of the shell 1 contains water liquid with a certain liquid level, so that each core tube 2 floats on the liquid level inside the shell 1.
Further, in the preferred embodiment, a central plug 3 is provided corresponding to the third housing 103 for tightening and closing the bottom opening of the housing 1. Specifically, the central plug 3 in the preferred embodiment is made of rubber, and has an "i" shaped longitudinal cross section, and includes a first plate 301 and a second plate 302 parallel to each other, and a neck 303 having an outer diameter smaller than that of the two plates is coaxially disposed between the two plates. Furthermore, the central plug 3 can extend into the opening end of the third housing 103 through the first plate 301 and the neck 303, and the inner wall of the opening of the third housing 103 can be tightly closed to the outer periphery of the neck 303, and the end of the third housing 103 abuts against the end face of the second plate 302 facing the first plate 301, as shown in fig. 2.
Accordingly, a closing-in assembly 4 is provided at the outer periphery of the end of the third shell 103 for securely tightening the third shell 103 at the outer periphery of the neck 303. In a preferred embodiment, the cuff assembly 4 is a double wire throat band, which may be provided in a plurality at axial intervals to ensure that the third shell 103 can be tightly tightened around the outer circumference of the neck 303, thereby achieving a seal at the bottom of the shell 1.
Further, a pressure regulating valve 5 and a one-way valve 6 are arranged in the central plug 3 in the preferred embodiment, and the two valve bodies are respectively communicated with two axial sides of the central plug 3, namely, the inner side and the outer side of the shell 1. Meanwhile, the one-way valve 6 is arranged in a manner that water liquid outside the housing 1 can be sucked into the housing 1 through the one-way valve 6, and the water liquid inside the housing 1 cannot be discharged through the one-way valve 6. Accordingly, the pressure regulating valve 5 functions to control the maximum pressure in the inner cavity of the housing 1, and when the pressure inside the housing 1 reaches the maximum pressure, the pressure regulating valve 5 is opened, so that the water in the housing 1 can be discharged from the pressure regulating valve 5.
In actual installation, the multicore anti-collision capsules are preferably arranged on the periphery of the protected object in a single or multiple combination mode, for example, a plurality of anti-collision capsules are arranged on the periphery of a pier in a surrounding mode. When the anti-collision capsule is arranged, the shell 1 of each anti-collision capsule is filled with the core pipe 2 filled with air according to the use requirement, and a certain amount of water liquid is sucked into the shell 1 after the bottom of the shell 1 is tightened, so that each core pipe 2 can float on the liquid level in the shell 1 respectively, and the bottom of each anti-collision capsule floats on the water surface with the top after being immersed into the water for a certain depth.
When the anti-collision capsule is impacted and deformed (the shell 1 is deformed and each core tube 2 is extruded and deformed), the pressure in the shell 1 rises and exceeds the maximum pressure of the pressure regulating valve 5, so that water liquid in the shell 1 is sprayed out from the central plug 3 at the bottom of the shell 1 through the pressure regulating valve 5, the impact force borne by the capsule is released, and the internal pressure of the capsule is reduced. The impact force transmitted to the bridge pier by the capsule is usually the product of the internal pressure of the capsule and the contact area of the capsule and the bridge pier, the impact force transmitted to the bridge pier during collision can be correspondingly reduced by reducing the internal pressure of the capsule, namely, the maximum impact force transmitted to the bridge pier by the capsule is limited by the arrangement of the pressure regulating valve 5.
After the impact is removed, each core tube 2 gradually recovers the original shape under the action of compressed gas in the tube, so that the shell 1 is supported, and the appearance of the shell 1 is recovered. Meanwhile, in the process of restoring the shape of the shell 1, since the shell 1 can be regarded as being switched from the 'collapsed' state to the 'expanded' state, so that a pressure difference exists between the inside and the outside of the shell 1, namely the pressure outside the shell 1 is greater than the pressure inside the shell 1, at this time, the check valve 6 on the central plug 3 starts to suck the water liquid outside the shell 1 into the shell 1 until the interior of the shell 1 is restored to the initial state.
Obviously, above-mentioned anticollision capsule can realize manifold cycles after setting up and use, and each anticollision capsule possesses the characteristic of automatic recovery, has fully avoided the frequent maintenance of anticollision capsule, has maintained. According to practical application, the anti-collision capsule in the preferred embodiment only needs to periodically check whether the gas in each core tube 2 is sufficient or not and perform a corresponding inflation process, so that the overhaul and maintenance processes of the anti-collision device are greatly simplified.
The utility model provides a many core pipe anticollision capsule, a structure is simple, the setting is simple and convenient with the maintenance, can effectively realize the striking protection of pier isotructure, fully absorb and release the impact force that the striking produced, and can the effective control striking in-process anticollision capsule transmit the effort for the pier, ensure that the striking impact force is no longer than the bearing capacity by the protected object, and simultaneously, after the striking is removed, the anticollision capsule can realize recovering fast under the effect of core pipe, make the anticollision capsule can recover the state before the striking fast, effectively simplify the maintenance process of anticollision capsule, better application prospect and spreading value have.
It will be understood by those skilled in the art that the foregoing is merely a preferred embodiment of the present invention, and is not intended to limit the invention to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
