Description

Technical Field

[0001] The invention relates to the technical field of bridge pier protection, and in particular to a floating steel-clad composite anti-collision device. Background Art

[0002] With the rapid development of marine engineering, port construction, cross-sea bridges and other fields, the performance requirements of anti-collision devices as core safety components for protecting key infrastructure (such as bridge piers, docks, and ships) are increasing. In the pier protection scenario, in order to protect the bridge piers, anti-collision protection rings are generally installed on the outer periphery of the bridge piers. In order to facilitate transportation, the anti-collision protection ring is generally assembled by splicing multiple units, and the two adjacent units are fixedly connected by flanges.

[0003] After searching, the Chinese patent (publication number: CN216973091U) disclosed "a floating anti-collision device for bridge piers, including an anti-collision ring, the anti-collision ring includes at least two unit bodies connected end to end in sequence, the unit body includes a shell with openings at both ends, the shell is made of steel-coated composite material, and a first flange chamber, a closed chamber and a second flange chamber are arranged in the shell from the beginning to the end, and the walls of the first flange chamber and the second flange chamber are provided with an anti-corrosion layer."

[0004] However, in the process of implementing relevant technologies, this type of patent has certain technical defects:

[0005] First, although this type of patent mainly improves the anti-corrosion ability by setting an anti-corrosion layer on the outer layer of the anti-collision ring, in actual use, it mainly responds to low-speed collisions of ships docking (bridge pier maintenance) and violent collisions of ships under high-speed loss of control. This requires the protective ring to have a strong buffering ability. However, this type of protective ring has a single-layer protection design, which leads to serious lack of protection ability;

[0006] Second, since the hull is generally a structure that is wide at the top and narrow at the bottom, the hull will tilt during a high-speed collision, causing the collision area to expand and exceed the protection area of ​​the anti-collision ring. The existing protection area of ​​the anti-collision ring is fixed and cannot be extended, so that the hull can directly contact the bridge pier, thereby causing damage to the bridge pier. In view of this, the present invention proposes a floating steel-clad composite anti-collision device. Summary of the invention

[0020] 2. When the collision ship collides at high speed, the outer sealed steel box will be displaced and release energy due to the excessive impact force, so that the shock absorber 1 applies a vertical thrust greater than the gravity of the inner sealed steel box to the inner sealed steel box, so that the inner sealed steel box moves upward along the pier, which can extend the protection area in the direction corresponding to the collision ship. At the same time, the card block is disengaged from the card slot, and the lateral restriction on the guide plate is released at this time, so that the guide plate moves laterally under the action of the guide plate, so that the slider slides along the guide rod and squeezes the reset spring 1, so that the reset spring 1 generates a reverse elastic force for lateral buffering. At the same time, under the lateral guidance of the guide plate, the driving trajectory of the collision ship deviates from the outer sealed steel box, so as to avoid the driving kinetic energy of the collision ship being completely released to the outer sealed steel box to cause serious damage to the entire anti-collision device.

[0033] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 10 As shown, this embodiment proposes a floating steel-clad composite anti-collision device, including two parallel planar buffer modules 1, both ends of the two planar buffer modules 1 are provided with U-shaped buffer modules 2, the two U-shaped buffer modules 2 and the two planar buffer modules 1 form a ring-shaped structure sleeved on the outside of the pier 3, the planar buffer modules 1 and the U-shaped buffer modules 2 have different shapes, and the planar buffer modules 1 and the U-shaped buffer modules 2 have the same layout structure;

[0035] The planar buffer module 1 includes an outer sealed steel box 11, both ends of which are fixedly connected with connecting plates 12, and the two connecting plates 12 are fixedly connected with the corresponding U-shaped buffer modules 2 by bolts. Shock absorbers 13 are hinged at both ends of the back of the outer sealed steel box 11, and the ends of the two shock absorbers 13 away from the outer sealed steel box 11 are hinged with inner sealed steel boxes 14 arranged in parallel with the outer sealed steel box 11. The inner sealed steel box 14 has the same length as the outer sealed steel box 11, and the inner sealed steel box 14 has the same internal structure as the outer sealed steel box 11. The inner sealed steel box 14 is in conflict with the outer wall of the pier 3, and the inner sealed steel box 14 can move along the outer wall of the pier 3. The front of the outer sealed steel box 11 is provided with a guide mechanism 15 which guides the collision ship to deviate by cooperating with the inner sealed steel box 14 to move upward.

[0036] Through the design of the outer sealed steel box 11, the inner sealed steel box 14 and the shock absorber 13, multi-layer buffering of the collision ship can be achieved, thereby greatly improving the overall buffering capacity, which is sufficient to cope with the buffering of the collision ship at a low speed. In addition, in a high-speed collision of the collision ship, the outer sealed steel box 11 will be displaced and release energy due to the excessive impact force, so that the shock absorber 13 applies a vertical thrust greater than the gravity of the inner sealed steel box 14 to the inner sealed steel box 14, so that the inner sealed steel box 14 moves upward along the pier 3, thereby extending the protection area in the direction corresponding to the collision ship, thereby avoiding the problem of the collision ship tilting to expand the collision area and directly contacting the pier 3 to cause damage to it.

[0037] Furthermore, the outer sealed steel box 11 includes a steel cladding 111, a honeycomb aluminum layer 112 is fixedly connected to the inner side of the steel cladding 111, the inner side of the honeycomb aluminum layer 112 is filled with polyurethane foam 113, and the outer side of the steel cladding 111 is fixedly connected to a galvanized layer 114. The steel cladding 111 has good rigidity, the honeycomb aluminum layer 112 can absorb energy during a collision, and the polyurethane foam 113 can provide sufficient buoyancy to the outer sealed steel box 11, ensuring that the outer sealed steel box 11 floats with changes in the water level and dynamically protects the bridge pier 3.

[0038] Furthermore, the guide mechanism 15 includes a mounting seat 151 fixedly connected to the outside of the outer sealed steel box 11, an inner cavity 152 is provided on the inner side of the mounting seat 151, a guide rod 154 is fixedly connected to the inner side of the inner cavity 152, a slider 153 is slidably connected to the guide rod 154, one end of the slider 153 is fixedly connected to a guide plate 156 arranged parallel to the outer sealed steel box 11, and both ends of the guide rod 154 are sleeved with a return spring 155, and the two return springs 155 are provided. 5 abuts against the inner wall of the inner cavity 152, and the other ends of the two return springs 155 abut against the slider 153. A locking member 158 for limiting the lateral movement of the guide plate 156 is provided at the bottom of the guide plate 156. The locking member 158 includes an L-shaped plate 1581 fixedly connected to the bottom of the guide plate 156, and a slot 1582 is provided at one end of the L-shaped plate 1581. A block 1583 inserted into the inner side of the slot 1582 is fixedly connected to the interior of the inner sealed steel box 14.

[0039] When the collision ship is docked at a low speed, the impact force on the outer sealed steel box 11 is small. At this time, the inner sealed steel box 14 and the outer sealed steel box 11 remain relatively still in the vertical direction, and the clamping block 1583 remains inserted in the clamping groove 1582, so that the guide plate 156 can be restricted from lateral movement, so that the collision ship can be stably docked at a predetermined position;

[0040] When the collision ship collides at high speed, the outer sealed steel box 11 will be displaced and release energy due to the excessive impact force, so that the shock absorber 13 applies a vertical thrust greater than the gravity of the inner sealed steel box 14 to the inner sealed steel box 14, so that the inner sealed steel box 14 moves upward along the pier 3, so that the protection area corresponding to the collision ship can be extended. At the same time, the block 1583 is disengaged from the slot 1582, and the lateral restriction on the guide plate 156 is released at this time, so that the guide plate 156 moves laterally under the action of the guide plate 156, so that the slider 153 slides along the guide rod 154 and squeezes the return spring 155, so that the return spring 155 generates a reverse elastic force for lateral buffering, and at the same time, under the lateral guidance of the guide plate 156, the driving trajectory of the collision ship deviates from the outer sealed steel box 11, so as to avoid the driving kinetic energy of the collision ship being completely released to the outer sealed steel box 11 to cause serious damage to the entire anti-collision device.

[0041] Furthermore, both upper and lower ends of the mounting seat 151 are provided with a slide groove 159 arranged parallel to the inner cavity 152, and both ends of the back side of the guide plate 156 are provided with a plurality of rolling members 157 that are clearance-matched with the slide groove 159. Both upper and lower ends of the mounting seat 151 are provided with a slide groove 159 arranged parallel to the inner cavity 152, and both ends of the back side of the guide plate 156 are provided with a plurality of rolling members 157 that are clearance-matched with the slide groove 159. The rolling member 157 includes a second shock absorber 1571, one end of the second shock absorber 1571 is fixedly connected to the guide plate 156, and the other end of the second shock absorber 1571 is fixedly connected to a connecting seat 1572, and a roller 1573 is rotatably connected to the inner side of the connecting seat 1572, and the roller 1573 can roll along the corresponding slide groove 159.

[0042] Shock absorber 2 1571 provides auxiliary buffering for the outer sealed steel box 11, which can further enhance the overall buffering capacity. The design of roller 1573 and shock absorber 2 1571 can reduce the friction between the guide plate 156 and the mounting seat 151, so that the guide plate 156 can smoothly realize the lateral guiding function.

[0043] Furthermore, elastic members 1584 are provided at both ends of the inner side of the slot 1582, and the elastic member 1584 includes a slide bar 15841 slidably connected to the inner wall of the slot 1582, one end of the slide bar 15841 is fixedly connected to an arc guide block 15844, and the other end of the slide bar 15841 is fixedly connected to a guide block 15843, and a mounting groove 15842 slidably matched with the guide block 15843 is provided on the inner side of the L-shaped plate 1581, and a second return spring 15845 is sleeved on one end of the inner side of the mounting groove 15842, one end of the second return spring 15845 is in contact with the guide block 15843, and the other end of the second return spring 15845 is in contact with the inner wall of the mounting groove 15842, the width of the block 1583 is smaller than the opening width of the slot 1582, and the maximum spacing between the two slots 1582 is the same as the width of the block 1583.

[0044] The design of the second return spring 15845 allows the arc guide block 15844 to maintain elastic contact with the block 1583, so that when the block 1583 is inserted into the slot 1582, the arc guide block 15844 can smoothly guide the block 1583 into the slot 1582 to achieve lateral restriction on the guide plate 156, ensuring that the collision ship will not be offset under the action of the guide plate 156 when docking at a low speed.

[0045] Working principle: When the collision ship is docked at a low speed, the design of the outer sealed steel box 11, the inner sealed steel box 14 and the shock absorber 13 can achieve multi-layer buffering for the collision ship, thereby greatly improving the overall buffering capacity, which is sufficient to cope with the buffering of the collision ship docking at a low speed; at this time, the inner sealed steel box 14 and the outer sealed steel box 11 remain relatively still in the vertical direction, and the card block 1583 remains inserted in the card slot 1582, so that the guide plate 156 can be restricted from lateral movement, so that the collision ship can be stably docked at a predetermined position;

[0046] When the collision ship collides at high speed, the outer sealed steel box 11 will be displaced and release energy due to the excessive impact force, so that the shock absorber 13 applies a vertical thrust greater than the gravity of the inner sealed steel box 14 to the inner sealed steel box 14, so that the inner sealed steel box 14 moves upward along the pier 3, so that the protection area corresponding to the collision ship can be extended, and at the same time, the block 1583 is disengaged from the card slot 1582, and the lateral restriction on the guide plate 156 is released at this time, so that the guide plate 156 moves laterally under the action of the guide plate 156, so that the slider 153 slides along the guide rod 154 and squeezes the return spring 155, so that the return spring 155 generates a reverse elastic force for lateral buffering, and at the same time, under the lateral guidance of the guide plate 156, the driving trajectory of the collision ship deviates from the outer sealed steel box 11, so as to avoid the driving kinetic energy of the collision ship being completely released to the outer sealed steel box 11 to cause serious damage to the entire anti-collision device, and the entire structure can adjust the protection posture according to the collision speed of the collision ship, greatly improving the overall protection capability.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
