Description

Technical Field

[0001] This utility model relates to the field of protection technology, and in particular to a simple, self-recovering underwater bridge pier anti-collision device. Background Technology

[0002] The booming development of water transport has made the risk of collisions between ships and bridge piers increasingly prominent. Once a ship collision occurs, it can not only cause tragedies involving the destruction of the vessel and loss of life, but also trigger structural damage to the bridge, leading to a series of chain reactions such as traffic disruptions and energy supply disruptions, posing a serious threat to socio-economic development and public safety. Therefore, installing effective anti-ship collision facilities on bridges is particularly urgent and necessary.

[0003] Various types of collision avoidance facilities have been developed both domestically and internationally, such as fixed abutments, independent collision avoidance piles, composite material casings, and floating fender systems. However, existing collision avoidance facilities still face several prominent challenges in their practical application. For example, traditional facilities (such as reinforced concrete structures) often suffer from heavy weight, complex installation processes, and long construction periods, requiring the use of large-scale waterborne equipment, resulting in high costs and significant disruption to normal navigation. Furthermore, some facilities are too large and require custom molding, making them difficult to install on existing old bridge piers or in special waterways with rapid currents and complex geology. This approach aims to significantly lower the implementation threshold for collision avoidance projects, providing an economical and efficient technical means to broadly improve the collision safety level of both in-service and newly built bridges. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a simple, self-recovering underwater bridge pier anti-collision device that is simple in structure, easy to install, and self-recovering. This device solves the problem that traditional anti-collision measures are either irreparable or have very high repair costs when damaged.

[0005] This utility model is accomplished by the following technical solution: a simple assembly self-recovering underwater bridge pier anti-collision device, comprising multiple anti-collision units, adjacent anti-collision units being detachably connected by at least one set of connecting parts, the anti-collision unit comprising a fluffy body layer, an energy-absorbing and resetting mechanism and a tail rubber ball, the fluffy body layer having a supporting connecting member inside, the front end of the energy-absorbing and resetting mechanism being fixed on the supporting connecting member, and multiple tail rubber balls being fixed at the end of the energy-absorbing and resetting mechanism.

[0006] Furthermore, the energy-absorbing and resetting mechanism includes a diagonal brace and a spring. The front ends of the diagonal brace and the spring pass through the bottom of the fluffy body layer and are fixedly connected to the support connecting member. The ends of the diagonal brace and the spring are provided with rubber balls.

[0007] Furthermore, the end of the fluffy body layer away from the energy-absorbing and resetting mechanism is made of honeycomb rubber material.

[0008] Furthermore, the connecting component includes a male end and a female end, which are symmetrically connected on both sides of the anti-collision unit, and the ends of the male end and the female end are fixedly connected to the supporting connecting member.

[0009] Furthermore, the connecting component is a pin-plug structure.

[0010] Furthermore, both the diagonal brace and the bottom of the spring are fixed with pads, which are wrapped inside the rubber ball.

[0011] Furthermore, the diagonal braces are arranged in a crisscross pattern.

[0012] Furthermore, the supporting connecting member is a steel plate.

[0013] The beneficial effects of this utility model are: 1. The anti-collision device consists of multiple anti-collision units, which are detachably connected by connecting parts. The number of anti-collision units can be selected according to the shape of the bridge pier, and they can be installed to fit the bridge pier through connecting parts. It is easy to install and can be applied to various new or existing bridge pier shapes.

[0014] 2. The anti-collision unit has a hollow structure, allowing water to pass through freely and minimizing the influence of ocean currents.

[0015] 3. The anti-collision unit is a separable structure. The anti-collision unit components can be prefabricated in the factory and then assembled, reducing on-site construction procedures. Damaged components can be replaced in a timely manner, resulting in low cost.

[0016] 4. The anti-collision unit consists of a fluffy body layer, an energy-absorbing and resetting mechanism, and a rubber ball. The three layers absorb force and dissipate energy, greatly increasing the energy dissipation effect.

Detailed Implementation

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] Reference Figures 1-3 This invention provides a simple, self-recovering underwater bridge pier anti-collision device, comprising multiple anti-collision units 1. Adjacent anti-collision units 1 are detachably rotatably connected by at least one set of connecting components 2 (preferably two sets). Each anti-collision unit 1 includes a porous layer 3, an energy-absorbing and resetting mechanism 4, and a tail rubber ball 5. The porous layer 3 has a supporting connecting member 6 inside. The front end of the energy-absorbing and resetting mechanism 4 passes through the bottom of the porous layer 3 and is fixed to the supporting connecting member 6. Multiple tail rubber balls 5 are fixed to the end of the energy-absorbing and resetting mechanism. The porous layer 3 is made of an elastic material, and the end of the porous layer away from the energy-absorbing and resetting mechanism is made of honeycomb-shaped rubber material 31. The honeycomb shape 31 can dissipate energy and increase the buoyancy of the anti-collision device. This device uses a porous layer 3, an energy-absorbing and resetting mechanism 4, and tail rubber balls 5, with three layers for force dissipation, greatly increasing the energy dissipation effect. Furthermore, the number of anti-collision units 1 is selected according to the shape of the bridge pier 7, and the anti-collision units are installed through connecting components, making installation extremely convenient. Furthermore, the anti-collision unit components are small in size and can be assembled into various shapes, making them suitable for various new or existing bridge piers and abutments, thus having a wide range of applications. The anti-collision device adopts a detachable structure, allowing the anti-collision unit components to be prefabricated in the factory and then assembled on-site, reducing on-site construction procedures. At the same time, when a single anti-collision unit component is damaged, only the damaged component needs to be replaced, without replacing the entire device, facilitating timely replacement, resulting in a long service life and low cost.

[0022] Furthermore, the energy-absorbing and resetting mechanism 4 includes a diagonal brace 41 and a spring 42, which are preferably made of corrosion-resistant material. The front ends of both the diagonal brace 41 and the spring 42 pass through the bottom of the bulky layer and are fixedly connected to the internal support connecting member 6. The ends of both the diagonal brace 41 and the spring 42 are provided with tail rubber balls 5. The diagonal brace 41 is preferably arranged diagonally and crosswise, and the spring 42 is preferably placed in the middle position. The support connecting member 6 is preferably a steel plate, which is wrapped inside the bulky layer 3. On the one hand, it ensures good rigidity during deformation, preventing damage from impact and increasing the rigidity of the bulky layer; on the other hand, it connects the spring and the diagonal brace. A pad 43 (preferably a steel pad) is fixed to the bottom of both the diagonal brace 41 and the spring 42. The support connecting member 6, the diagonal brace 41, and the pad 43 are welded to form a rigid whole. The pad 43 is wrapped inside the rubber ball 5 at the tail. The rubber ball 5 can prevent the spring and the diagonal brace from directly contacting the pier, increase the mobility of the spring and the diagonal brace, protect the pier, and at the same time play a role in energy dissipation.

[0023] The connecting component 2 preferably has a pin-fit structure or a rotatable snap-fit ​​structure. The connecting component includes a male end 21 and a female end 22, symmetrically connected on both sides of the anti-collision unit. The ends of the male end 21 and female end 22 pass through the loose body layer and are fixedly connected to the supporting connecting component 6. When installing the anti-collision device, the male end 21 and female end 22 of adjacent anti-collision units are connected together, forming a rotatable connection. This rotatable structure absorbs some of the water flow impact, reducing the impact of ocean currents. The rotatable connection also facilitates assembly into various shapes, suitable for various new or existing bridge pier shapes. The connecting component 2 creates a gap between adjacent anti-collision units, and the energy-absorbing and resetting mechanism 4 also has a hollow structure, making the anti-collision device a hollow structure that allows water to pass freely, reducing the impact of ocean currents.

[0024] The water immersion depth of this device is determined based on the buoyancy ratio. This is achieved by adjusting the volume of the bulkhead, the volume of the rubber ball, and the weight of the steel plate and diagonal braces. The dimensions of the steel plate are also determined by the water immersion depth and the stiffness of the bulkhead. This allows the device to float directly in the water without the need for support or anchoring devices, offering significant advantages for the protection of deep-water bridge piers and making it widely applicable.

[0025] Collision protection principle: Multiple collision protection units 1 are spliced ​​together by connecting parts 2 and wrap around the outer edge of the bridge pier. When a ship hits the collision protection device, the hull first contacts the honeycomb front end of the loose body layer 3, and the loose body layer 3 dissipates energy through deformation. At the same time, the spring 42 is compressed, and the contraction of the spring 42 drives the movement of the diagonal brace 41, which can provide a reaction force to block the impact of the hull on the bridge pier and protect the bridge pier. The tail end of the energy absorption and reset mechanism 4 is wrapped with a rubber ball 5 to avoid direct contact between the energy absorption and reset mechanism and the bridge pier. When the ship hits, the movement of the spring and the diagonal brace can be achieved by the deformation and movement of the rubber ball 5, and the deformation of the rubber ball also provides energy dissipation. After the ship leaves, the loose body layer 3 (elastic body) automatically recovers, and the spring 42 restores the device to its original state.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
