Description
Technical Field
The invention belongs to the technical field of structural protection, and particularly relates to a multi-core-tube anti-collision capsule.
Background
In recent years, as the number of vessels sailing on rivers increases, the tonnage increases, and the occurrence of the event that the vessels strike piers occurs. Bridge collision often causes catastrophic consequences such as bridge structural damage, cargo leakage, environmental pollution, casualties, and the like. Therefore, safety measures or protection devices are often arranged on bridge piers to ensure the stability and safety of the structure under the impact of the ship.
At present, common bridge pier protection devices can be divided into two main types, namely direct construction and indirect construction. The direct construction means that the protection device is directly constructed on the protected pier, and after the collision occurs, the collision force directly acts on the protected pier through the protection device. The indirect construction means that the protection device is not directly connected with the protected bridge, and the impact force does not directly act on the protected bridge. For both types of protection devices, although protection of the structure can be achieved to some extent, certain drawbacks exist respectively.
For example, for the indirectly constructed guard, the impact force generated when the guard is bumped after being arranged can be absorbed by the guard, and the guard does not act on the protected pier, so that the guard has a strong guard effect on the pier. However, the indirectly constructed protecting device is often separated from the protected bridge pier by a certain distance, so that the protecting device needs to occupy a river channel or a water area, and the maintenance engineering amount is often large. In contrast, the protection devices which are directly constructed are generally directly constructed on the bridge pier to be protected, and are mainly classified into three types of elastic deformation type, crushing (plastic) deformation type and displacement type. After the elastic deformation type protective device is impacted, although elastic recovery can be achieved, and maintenance work is small, the elastic deformation type protective device can only be suitable for impact with small energy, and once the impact exceeds the elastic deformation range, the bridge pier can be directly impacted, so that serious accidents are caused. While crush deformation type protection devices and deflection type protection devices can absorb huge impact energy through plastic deformation and deflection of the devices, the maintenance and repair workload of the devices after each impact is large, and the application cost of the protection devices is high.
In view of the above, the applicant proposes a prior patent application CN201910731622.4, which specifically discloses a hydraulic anti-collision capsule, and by using the corresponding arrangement of each component in the anti-collision capsule and the combined operation of each component when impacted, the impact protection of the bridge pier is effectively realized, and the service life of the bridge pier structure is prolonged. However, the anti-collision capsule is complex in structure, and complex in assembly, maintenance and overhaul, so that the application and popularization of the anti-collision capsule are affected to a certain extent, and the bridge pier cannot be reliably protected.

Examples:
Referring to fig. 1, the multi-core tube anti-collision capsule in the preferred embodiment of the present invention includes a capsule-shaped housing 1, wherein a cavity structure is formed inside the housing 1, and a strip-shaped core tube 2 is filled in the housing, so that when the anti-collision capsule is impacted, absorption and release of impact force can be achieved through elastic deformation of the housing 1 and the core tube 2.
Specifically, in the preferred embodiment, the housing 1 is preferably of a "three-stage" design, comprising a first housing 101 at the top, a second housing 102 at the middle, and a third housing 103 at the bottom, the first housing 101 being disposed to protrude from the water surface during actual operation, the third housing 103 being partially or fully immersed in water. Meanwhile, the first shell 101 in the preferred embodiment is hemispherical, the second shell 102 is cylindrical with two open ends, namely, the top of the second shell 102 is sealed by the first shell 101, and correspondingly, the third shell 103 is in a special-shaped structure or a frustum-shaped structure as a whole due to bottom closing.
It can be appreciated that, in actual arrangement, the first housing 101, the second housing 102, and the third housing 103 are integrally formed, so as to ensure the integrity and tightness of the housings. Meanwhile, the case 1 in the preferred embodiment is a multi-layered structure in the thickness direction, which includes a rubber layer, a ply layer and a leakage preventing layer, which are sequentially disposed from the outside to the inside. Compared with the capsule body prepared by a single rubber layer, the strength of the shell 1 can be fully enhanced through the arrangement of the ply, and the tightness inside and outside the shell 1 can be effectively improved through the arrangement of the leakage-proof layer. Preferably, an openable and closable air discharge nozzle 104 is provided at the top of the first housing 101, the air discharge nozzle 104 being closable from outside the housing 1 and allowing communication between the inside and outside of the housing 1 when opened for water discharge and air discharge.
As shown in fig. 1, the housing 1 in the preferred embodiment has enclosed therein a plurality of core tubes 2 made of rubber material (core tubes 2 on the left side in fig. 1 are not shown), the axes of the respective core tubes 2 being parallel to each other and preferably parallel to the axis of the housing 1, as shown in fig. 1, i.e., when the housing 1 is disposed vertically, the respective core tubes 2 are disposed vertically, respectively. Meanwhile, in the preferred embodiment, the inner cavity of the shell 1 is squeezed by a plurality of core tubes 2 which are sequentially and closely arranged, so that the shell 1 is ensured to be 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 circular tube structure, the two ends can be further preferably arranged in a hemispherical shape, and an air charging nozzle (not shown in the figure) is arranged at the end part, so that the air charging and discharging process in the inner cavity of the core tube 2 is realized.
It will be appreciated that in the preferred embodiment parameters such as the length, outer diameter etc. of the core tube 2 may be adjusted correspondingly 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 housing 1 (based on the inner diameter of the second housing 102) is in the range of 0.1 to 0.2, for example in the preferred embodiment shown in fig. 2, the outer diameter of the core tube 2 is equal to 1/8 of the inner diameter of the housing 1. In addition, the core tubes 2 in the preferred embodiment are merely fitted in close contact with each other and are not connected to each other.
When in actual setting, the length of the core tube 2 is smaller than the length of the shell 1, and the inside of the shell 1 contains water with a certain liquid level, so that each core tube 2 floats on the liquid level inside the shell 1 respectively.
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 center 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 the outer diameters of the two plates is coaxially provided between the two plates. The central plug 3 may further extend into the opening end of the third housing 103 through the first plate 301 and the neck 303 thereof, so that the inner wall of the opening of the third housing 103 may be tightly attached 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 housing 103 for securely tightening the third housing 103 around the outer periphery of the neck 303. In the preferred embodiment, the closing-in assembly 4 is a double wire hose clamp, which may be provided in a plurality of axially spaced apart positions, to ensure that the third housing 103 can be sealingly tightened around the periphery of the neck 303, thereby effecting a seal at the bottom of the housing 1.
Further, in the preferred embodiment, a pressure regulating valve 5 and a one-way valve 6 are arranged in the central plug 3, and the two valve bodies are respectively communicated with the two axial sides of the central plug 3, namely, the two axial sides of the shell 1. Meanwhile, the one-way valve 6 is arranged in such a way that the water outside the housing 1 can be sucked into the housing 1 through the one-way valve 6, and the water in the housing 1 cannot be discharged through the one-way valve 6. Accordingly, the pressure regulating valve 5 functions to control the pressure maximum value of the inner cavity of the housing 1, and when the pressure inside the housing 1 reaches the pressure maximum value, the pressure regulating valve 5 is opened so that the water liquid inside the housing 1 can be discharged from the pressure regulating valve 5.
In practical arrangement, it is preferable to arrange the above-mentioned multicore crashproof capsule in a single or a plurality of combinations at the periphery of the object to be protected, for example, a plurality of crashproof capsules arranged in a surrounding manner at the periphery of the bridge pier. When the anti-collision capsule is arranged, the shell 1 of each anti-collision capsule is filled with the filled core tube 2 according to the use requirement, a certain amount of water is sucked into the shell 1 after the bottom of the shell 1 is tightly tied, so that each core tube 2 can float on the liquid surface in the shell 1 respectively, and the bottom of each anti-collision capsule floats on the water surface at the top after being immersed in water for a certain depth.
When the anti-collision capsule is impacted to deform (the shell 1 deforms and each core tube 2 extrudes to deform), the pressure in the shell 1 rises to exceed the pressure maximum value of the pressure regulating valve 5, so that water in the shell 1 is sprayed out of the center plug 3 at the bottom of the shell 1 through the pressure regulating valve 5, the impact force born 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 often the product of the internal pressure of the capsule and the contact area of the capsule and the bridge pier, and the impact force transmitted to the bridge pier during impact 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 returns to its original shape under the action of compressed gas in the tube, so that the shell 1 is supported and the shape of the shell 1 is restored. Meanwhile, in the process of recovering the shape of the shell 1, since the shell 1 can be regarded as being switched from the 'collapsed' state to the 'expanded' state, a pressure difference exists between the inside and the outside of the shell 1, that is, the pressure outside the shell 1 is greater than the pressure inside the shell 1, at this time, the one-way valve 6 on the center plug 3 starts to suck the water outside the shell 1 into the shell 1 until the inside of the shell 1 is recovered to the initial state.
Obviously, the anti-collision capsule can be recycled for a plurality of times after being arranged, and each anti-collision capsule has the characteristic of automatic recovery, so that frequent overhauling and maintenance of the anti-collision capsule are fully avoided. According to the practical application, it is found that for the anti-collision capsule in the preferred embodiment, only the condition that whether the gas in each core tube 2 is sufficient is checked regularly and the corresponding inflation process is performed is needed, which greatly simplifies the overhauling and maintenance process of the anti-collision device.
The multi-core pipe anti-collision capsule is simple in structure, convenient to set and maintain, capable of effectively realizing collision protection of structures such as piers and the like, fully absorbing and releasing impact force generated by collision, capable of effectively controlling acting force transmitted to the piers by the anti-collision capsule in the collision process, and ensuring that the impact force does not exceed the bearing capacity of a protected object.
It will be readily appreciated by those skilled in the art that the foregoing description is merely a preferred embodiment of the invention and is not intended to limit the invention, but any modifications, equivalents, improvements or alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
