Description

Technical Field

[0001] This invention relates to the field of bridge engineering technology, and in particular to an ice-breaking device for the main piers of extra-large bridges. Background Technology

[0002] In cold regions, when rivers freeze over in winter, the flowing ice can exert tremendous impact on bridge piers, causing concrete spalling, exposed rebar, and even structural damage. In severe cases, this can affect the bridge's load-bearing capacity and lifespan, posing safety hazards. Therefore, ice protection and de-icing of bridge piers is one of the core issues in the construction and operation of bridge projects in cold regions. Currently, the industry mainly mitigates this problem by enhancing the piers' own impact resistance or installing external ice-breaking devices. Enhancing the piers' own impact resistance primarily involves thickening the concrete protective layer, adding impact-resistant rebar, or using high-strength composite materials for pier construction. While these methods can improve the piers' resistance to ice impact to some extent, they significantly increase construction costs and difficulty, and cannot fundamentally mitigate the impact of ice. Long-term structural damage will still occur, resulting in high maintenance costs. However, the current method of setting up external icebreaking devices still has many shortcomings. Existing external icebreaking devices are mainly divided into two categories: rigid icebreakers and flexible buffer icebreakers. Rigid icebreakers are mostly straight plate-shaped or simple conical structures fixedly installed on the water-facing side of the bridge pier. They rely on their own rigidity to directly resist the impact of ice and break the ice. However, such icebreakers have a simple structure and limited ice-breaking surface. When faced with large-area, thick ice impacts, the ice-breaking efficiency is extremely low. Moreover, the impact force of the ice layer is directly transmitted to the connection between the icebreaker and the bridge pier, causing problems such as weld cracking, structural deformation, and even detachment of the icebreaker. The resistance to repeated impacts is extremely poor, and it cannot adapt to the working conditions of repeated impacts from ice layers in winter. Flexible buffer icebreakers mostly use rubber pads and other buffer components in conjunction with simple ice-breaking structures. Although they can buffer some of the impact force of the ice layer, the coordination between the buffer structure and the ice-breaking structure is poor, and the buffer stroke is limited. When faced with instantaneous high-intensity ice impacts, the buffering effect is not good, and a large amount of impact force is still transmitted to the main pier. At the same time, some devices are cumbersome to install, cannot be retrieved, and lack guiding and anti-slip structures, making them prone to loosening. To address the aforementioned issues, this application proposes an ice-breaking device for the main piers of extra-large bridges. Summary of the Invention

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an ice-breaking device for the main piers of extra-large bridges, which solves the problems of poor resistance to repeated impacts, low efficiency, and insufficient adaptability to complex ice conditions that are common in existing ice-breaking structures.

[0004] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: an ice-breaking device for the main pier of a super-large bridge, comprising two semi-circular fixing plates symmetrically distributed, a base fixedly connected to the bottom of each semi-circular fixing plate, an ice-breaking cone assembly mounted on the base, the ice-breaking cone assembly comprising a main cone and an auxiliary cone, the side surface of the main cone being a cone with a slope of 30°, the side surface of the auxiliary cone being a cone with a slope of 45°, the tail end of the auxiliary cone being fixedly connected to the main cone, and the auxiliary cones being arranged in a ring array around the main cone; A buffer assembly is provided between the base and the main cone. The buffer assembly includes a sleeve, a sliding column, and a spring. The lower surface of the sleeve is fixedly connected to the base. The sleeve is fitted onto the lower end of the sliding column, and the lower end of the sliding column is slidably connected to the sleeve. The upper end of the sliding column is fixedly connected to the auxiliary cone. The spring is fitted onto the outside of the sleeve and the sliding column. The lower end of the spring is fixedly connected to the base, and the upper end of the spring is fixedly connected to the main cone.

[0005] By adopting the above technical solution, the device is sleeved and fixed on the outside of the pier. The ice-breaking cone assembly is located on the water-facing side. When the ice block hits the cone surface of the main cone, the cone surface decomposes it into radial force. The auxiliary cone further breaks the edge ice layer. The synergistic effect of the main cone and the auxiliary cone can cover a larger ice-breaking area, effectively extend the structural life and improve the ice-breaking efficiency.

[0006] Preferably, the inner wall of the semi-circular fixing plate is provided with an anti-slip composite plate, which is composed of multiple layers of rubber and metal composite plate.

[0007] By adopting the above technical solution and setting an anti-slip composite plate, not only can the anti-slip performance of the semi-circular fixing plate be improved after it is engaged, thus preventing the device from loosening and falling, but the impact resistance can also be improved.

[0008] Preferably, a guide mechanism is provided between the semi-circular fixing plate and the main cone. The guide mechanism includes a guide rod and a sliding sleeve. The upper end of the guide rod is fixedly connected to the anti-slip composite plate, the lower end of the guide rod is fixedly connected to the base, the sliding sleeve is sleeved on the side surface of the guide rod, and the tail end of the sliding sleeve is fixedly connected to the main cone.

[0009] By adopting the above technical solution and setting a guiding mechanism, when the main cone is hit by an ice block, the cone surface decomposes it into a radial component force, causing the main cone to slide downward along the direction of the guide rod, and then, in conjunction with the buffer assembly, buffering the impact of the floating ice.

[0010] Preferably, bolts are inserted at both ends of the semi-circular fixing plate, and the ends of the bolts are threaded with nuts. The number of bolts is four and they are distributed in a rectangular array.

[0011] By adopting the above technical solution and setting bolts and nuts, during installation, you only need to clip the two semi-circular fixing plates on the outside of the pier, insert the bolts and tighten the nuts to fix the device at the specified height of the pier. The operation is simple and convenient, and the dismantling is also simple, making the device recyclable.

[0012] Preferably, the main cone is provided with a support, and a striking component is installed in a circular array on the support. The striking component includes a driving mechanism and a reciprocating mechanism.

[0013] By adopting the above technical solution and setting up a striking component, the flowing water energy is used to drive the reciprocating mechanism to operate, thereby striking the ice blocks that have not been broken by the main cone and auxiliary cone again, breaking the ice blocks, further reducing the impact force of the ice blocks on the pier, and at the same time, the water energy is used to make it strike continuously, which greatly improves the ice breaking efficiency and reduces energy consumption.

[0014] Preferably, the driving mechanism includes a water wheel, a rotating rod, a first bevel gear, a second bevel gear, and a turntable. The lower end of the rotating rod is fixedly connected to the water wheel, the upper end of the rotating rod is fixedly connected to the first bevel gear, the rotating rod passes through the interior of the main cone, the side surface of the first bevel gear meshes with the second bevel gear, and the end of the second bevel gear is fixedly connected to the turntable.

[0015] By adopting the above technical solution and setting up a drive mechanism, when the oncoming water flow impacts the water wheel, it drives the water wheel to rotate. The water wheel drives the rotating rod, the rotating rod drives the first bevel gear, the first bevel gear drives the second bevel gear, and the second bevel gear drives the turntable to rotate.

[0016] Preferably, the turntable is fixedly connected with four pressure rods arranged in a circular array.

[0017] By adopting the above technical solution and setting a pressure rod, when the turntable rotates, the pressure rod repeatedly presses the tail end of the L-shaped reciprocating rod, thereby providing kinetic energy to the reciprocating mechanism and breaking the ice.

[0018] Preferably, the reciprocating mechanism includes an L-shaped reciprocating rod, a cone, and a tension spring. The upper end of the bracket is hinged to the L-shaped reciprocating rod, the lower end of the L-shaped reciprocating rod is fixedly connected to the cone, the upper end of the tension spring is connected to the L-shaped reciprocating rod, and the lower end of the tension spring is connected to the main cone.

[0019] By adopting the above technical solution and setting up a reciprocating mechanism, when the pressure rod repeatedly squeezes the tail end of the L-shaped reciprocating rod, the L-shaped reciprocating rod swings repeatedly around the hinge between the bracket and the L-shaped reciprocating rod under the action of the tension spring, thereby causing the cone to repeatedly strike the ice block.

[0020] (III) Beneficial Effects In summary, this application includes at least one of the following beneficial technical effects: 1. The ice-breaking device for the main pier of the super-large bridge achieves the dual effects of efficient ice breaking and multi-level impact force buffering through the coordinated operation of the ice-breaking cone assembly and the buffer assembly. This solves the problems of low ice-breaking efficiency and poor resistance to repeated impacts in existing ice-breaking devices. The ice-breaking cone assembly adopts a combination structure of a main cone and a ring array of auxiliary cones. The 30° conical surface of the main cone can decompose the impact force of the ice layer into a radial component, while the 45° conical surface of the auxiliary cones further breaks the edge ice layer. The combination of the two greatly expands the ice-breaking coverage area. Compared with the traditional single rigid ice-breaking body, it can efficiently deal with large areas and thick ice. The layer impact significantly improves ice-breaking efficiency. The buffer component, through the linkage of sleeve, sliding column and spring, can guide the main cone to slide smoothly along the direction of force. The elastic deformation of the spring absorbs the instantaneous impact force of the ice layer, avoiding the impact force from being directly transmitted to the connection between the device and the bridge pier. This effectively prevents the weld of the ice-breaking body from cracking, deforming or falling off. At the same time, in conjunction with the guiding and limiting function of the guiding mechanism, it ensures that the buffer stroke is stable and controllable, greatly improving the device's resistance to repeated impacts. It is suitable for the complex working conditions of repeated ice layer impacts in winter, reduces the damage of ice layer impacts to the main pier, and extends the service life of the bridge.

[0021] 2. The ice-breaking device for the main pier of the super-large bridge achieves the dual benefits of adaptive ice breaking under complex ice conditions and energy saving through the coordinated linkage of the driving mechanism and reciprocating mechanism of the striking component. It overcomes the limitations of existing ice-breaking devices, such as insufficient handling of incompletely broken ice layers and high additional energy consumption. The striking component adopts a water-driven design, eliminating the need for an external power source. The flowing water energy drives the water wheel in the driving mechanism to rotate, which in turn drives the rotating rod and bevel gear transmission, causing the turntable to rotate smoothly. The annular array of pressure rods on the turntable repeatedly presses the tail end of the L-shaped reciprocating rod as the turntable rotates. With the reset action of the tension spring, the L-shaped reciprocating rod is driven. The rod continuously oscillates around the hinge point, thereby driving the cone spikes to continuously strike residual ice blocks or stubborn ice layers that have not been completely broken by the main cone and auxiliary cones. This effectively weakens the remaining impact force of the ice layer, prevents the residual ice layer from continuously hitting the main pier and causing damage, and achieves adaptive breaking of ice layers of different thicknesses and intensities. This enhances the device's adaptability to complex ice conditions. At the same time, it relies on natural water flow to achieve continuous ice-breaking operations, significantly reducing the energy consumption cost during the operation and maintenance of the device. Moreover, its compact structural design, in coordination with the ice-breaking cone components, further improves the overall ice-breaking effect and enhances the device's protection of the main pier of the super-large bridge.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This application will be described in further detail.

[0025] Example: Ice-breaking device for the main pier of a super-large bridge, refer to Figure 1 The system includes two semi-circular fixing plates 1, symmetrically distributed, with a base 2 fixedly connected to the bottom of each plate 1. An ice-breaking cone assembly is mounted on the base 2, comprising a main cone 3 and an auxiliary cone 4. The side surface of the main cone 3 is a 30° slope, and the side surface of the auxiliary cone 4 is a 45° slope. The tail end of the auxiliary cone 4 is fixedly connected to the main cone 3. The auxiliary cones 4 are arranged in a circular array around the main cone 3. A buffer assembly is provided between the base 2 and the main cone 3, comprising a sleeve 5, a sliding column 6, and a spring 7. The lower surface of the sleeve 5 is fixed to the base 2. The connection is as follows: sleeve 5 is fitted onto the lower end of sliding column 6, and the lower end of sliding column 6 is slidably connected to sleeve 5. The upper end of sliding column 6 is fixedly connected to auxiliary cone 4. Spring 7 is fitted onto the outside of sleeve 5 and sliding column 6. The lower end of spring 7 is fixedly connected to base 2, and the upper end of spring 7 is fixedly connected to main cone 3. By fitting and fixing this device onto the outside of the pier, the ice-breaking cone assembly is located on the water-facing side. When ice blocks hit the cone surface of main cone 3, the cone surface decomposes it into radial force. The auxiliary cone further breaks the edge ice layer. The synergistic effect of main cone 3 and auxiliary cone 4 can cover a larger ice-breaking area, effectively extend the structural life, and improve ice-breaking efficiency.

[0026] Reference Figure 3 and Figure 4The inner wall of the semi-circular fixing plate 1 is provided with an anti-slip composite plate 8, which is composed of multiple layers of rubber and metal composite plates. By setting the anti-slip composite plate 8, not only can the anti-slip performance of the semi-circular fixing plate 1 be improved after it is engaged, thus preventing the device from loosening and falling, but it can also improve the impact resistance. A guide mechanism is set between the semi-circular fixing plate 1 and the main cone 3. The guide mechanism includes a guide rod 9 and a sliding sleeve 10. The upper end of the guide rod 9 is fixedly connected to the anti-slip composite plate 8, and the lower end of the guide rod 9 is fixedly connected to the base 2. The sliding sleeve 10 is sleeved on the side surface of the guide rod 9, and the tail end of the sliding sleeve 10 is fixedly connected to the main cone 3. By setting the guide mechanism, when the main cone 3 is hit by an ice block, the cone surface decomposes it into a radial component force, causing the main cone 3 to slide downward along the direction of the guide rod 9, thereby cooperating with the buffer assembly to achieve buffering of the impact of the floating ice.

[0027] Reference Figure 1 and Figure 3 Bolts 11 are threaded through both ends of the semi-circular fixing plate 1. The ends of the bolts 11 are threaded with nuts 12. There are four bolts 11 distributed in a rectangular array. By setting the bolts 11 and nuts 12, during installation, you only need to clip the two semi-circular fixing plates 1 onto the outside of the pier, insert the bolts 11 and tighten the nuts 12 to fix the device at the specified height of the pier. The operation is simple and convenient, and the disassembly is also simple, making the device recyclable.

[0028] Reference Figure 4 , Figure 5 and Figure 7A support 13 is provided on the main cone 3. A striking component is installed in a ring array on the support 13. The striking component includes a drive mechanism and a reciprocating mechanism. By setting the striking component, the driving mechanism is driven by the flowing water to drive the reciprocating mechanism, thereby striking the ice blocks that have not been broken by the main cone 3 and the auxiliary cone 4 again, breaking the ice blocks, further reducing the impact force of the ice blocks on the pier. At the same time, the water energy is used to make it strike continuously, which greatly improves the ice breaking efficiency and reduces energy consumption. The drive mechanism includes a water wheel 14, a rotating rod 15, a first bevel gear 16, a second bevel gear 17 and a turntable 18. The lower end of the rotating rod 15 is fixedly connected to the water wheel 14, and the upper end of the rotating rod 15 is fixedly connected to the first bevel gear 16. The rotating rod 15 passes through the interior of the main cone 3. The side surface of the first bevel gear 16 meshes with the second bevel gear 17, and the end of the second bevel gear 17 is fixedly connected to the turntable 18. By setting up a drive mechanism, when the oncoming water flow impacts the waterwheel 14, it drives the waterwheel 14 to rotate. The waterwheel 14 drives the rotating rod 15, which in turn drives the first bevel gear 16. The first bevel gear 16 drives the second bevel gear 17, which in turn drives the turntable 18 to rotate. Four pressure rods 19 are fixedly connected to the turntable 18 and are arranged in a circular array. By setting up the pressure rods 19, when the turntable 18 rotates, the pressure rods 19 repeatedly press the tail end of the L-shaped reciprocating rod 20, thereby providing kinetic energy to the reciprocating mechanism and causing it to break the ice. The reciprocating mechanism includes an L-shaped reciprocating rod 20, a cone 21, and a tension spring 22. The upper end of the bracket 13 is hinged to the L-shaped reciprocating rod 20, and the lower end of the L-shaped reciprocating rod 20 is fixedly connected to the cone 21. The upper end of the tension spring 22 is connected to the L-shaped reciprocating rod 20, and the lower end of the tension spring 22 is connected to the main cone 3. By setting the reciprocating mechanism, when the pressure rod 19 repeatedly presses the tail end of the L-shaped reciprocating rod 20, the L-shaped reciprocating rod 20 swings repeatedly around the hinge between the bracket 13 and the L-shaped reciprocating rod 20 under the action of the tension spring 22, thereby causing the cone 21 to repeatedly strike the ice block.

[0029] The implementation principle of this invention is as follows: When fixing the device, two symmetrically distributed semi-circular fixing plates 1 are used to mount the device to the designated height of the main pier. Four bolts 11 arranged in a rectangular array pass through both ends of the semi-circular fixing plates 1 and are tightened with nuts 12 to achieve quick assembly, disassembly, and reuse of the device. The anti-slip composite plate 8 on the inner wall of the semi-circular fixing plate 1 is composed of multiple layers of rubber and metal composite plates, which can prevent the device from loosening and falling under the impact of ice and water flow, and enhance the overall impact resistance. The bottom of the semi-circular fixing plate 1 is fixedly connected to the base 2, and the ice-breaking cone assembly is installed on the base 2. The assembly includes a main cone 3 and auxiliary cones 4 arranged in a ring around it. The side surface of the main cone 3 is a cone with a slope of 30°. The auxiliary cone 4 has a 45° slope cone surface on its side surface and its tail end is fixed to the main cone 3. When working, the ice-breaking cone assembly is aligned with the water-facing surface. When the ice block hits the 30° cone surface of the main cone 3, the cone surface decomposes the impact force into a radial component force, causing the ice block to initially break and slide along the cone surface. The auxiliary cone 4 further breaks the edge ice layer and expands the ice-breaking area. At the same time, the bracket 13 on the main cone 3 is equipped with a ring array of striking components. In its driving mechanism, the water flow impacts the water wheel 14, which drives the rotating rod 15 to rotate. The rotating rod 15 passes through the main cone 3, and the first bevel gear 16 at the upper end meshes with and drives the second bevel gear 17, which in turn drives the turntable 18 to rotate. The four ring array of pressure rods 19 on the turntable 18 repeatedly press the tail end of the L-shaped reciprocating rod 20.

[0030] In the reciprocating mechanism of the striking component, the upper end of the L-shaped reciprocating rod 20 is hinged to the bracket 13, and the lower end is fixed with the cone 21. It is also connected to the main cone 3 through the tension spring 22. Under the pressure of the pressure rod 19 and the restoring force of the tension spring 22, the L-shaped reciprocating rod 20 swings repeatedly around the hinge, driving the cone 21 to continuously strike the unbroken residual ice, further weakening the impact force. Moreover, it is driven by water power and does not require additional energy consumption. The impact force generated by the ice layer is resolved by the buffer component and the guide mechanism. The buffer component includes a sleeve 5, a sliding column 6 and a spring 7. The lower surface of the sleeve 5 is fixed to the base 2, and it is sleeved on the lower end of the sliding column 6 and the two are slidably connected. The upper end of the sliding column 6 is fixed to the auxiliary cone 4. The spring 7 is sleeved on the outside of the sleeve 5 and the sliding column 6, and its two ends are connected to the base 2 and the main cone 3 respectively. The guide mechanism includes a guide rod 9 and a sliding sleeve 10. The upper and lower ends of the guide rod 9 are respectively connected to the anti-slip composite plate. The base 2 and the sliding sleeve 10 are fitted onto the guide rod 9 and the tail end is fixed to the main cone 3. When the main cone 3 is impacted, it slides down along the guide rod 9 under the limit of the guide mechanism, driving the sliding column 6 to slide down in the sleeve 5 and compress the spring 7. The elastic deformation of the spring 7 absorbs the instantaneous impact force, preventing the impact force from being transmitted to the connection between the device and the main pier, thus preventing damage to the device. At the same time, the guide mechanism ensures the stability of the buffer stroke, achieving effective buffering against the impact of floating ice, protecting the main pier from ice damage in all directions, and extending the service life of the bridge. The ice-breaking device for the main pier of this super bridge achieves all-round ice-breaking protection for the main pier through the coordinated linkage of the fixed structure, the ice-breaking structure and the buffer structure. Its working process first completes the device fixation, then breaks the ice layer through two-stage ice breaking, and at the same time, it works with the buffer guide mechanism to dissipate the impact force. All structures and digital symbols are precisely matched to ensure the stable and efficient operation of the device.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
