Description

Technical Field

[0001] This utility model relates to the technical field of bridge protection devices, and in particular to a bridge anti-collision device based on bridge safety performance. Background Technology

[0002] Bridges generally consist of a superstructure, substructure, bearings, and ancillary structures. The superstructure, also known as the bridge span structure, is the main structure that crosses obstacles. The substructure includes abutments, piers, and foundations. Bearings are force transmission devices installed at the support points between the bridge span structure and the piers or abutments. Ancillary structures refer to abutment approach slabs, tapered slopes, revetments, and diversion works, etc.

[0003] Bridge piers are typically located on the riverbed, and bridges have designated routes for ships to pass through. Generally, buffers such as tires are suspended from the bridge piers to correct ships that deviate from their designated routes. However, this system has drawbacks. Changes in water level can create height differences between the ship and the bridge, posing a risk when a ship collides with the bridge. Additionally, variations in the point of impact result in different impact forces, making buffering difficult. Furthermore, when a ship deviates from its designated course, the protective devices cannot prevent or correct its course. Utility Model Content

[0004] The purpose of this invention is to provide a bridge anti-collision device based on bridge safety performance, which has the advantages of mitigating impact force and preventing and correcting navigation deviation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bridge anti-collision device based on bridge safety performance, comprising:

[0006] The circular fixing part is fixed to the bridge and used to install the overall structure;

[0007] The sliding part is disposed on the circular fixed part and is pulled and slid by the recycling device fixedly connected to the circular fixed part;

[0008] The anti-collision mechanism has two parts, which are disposed on one side of the sliding part. When the two anti-collision mechanisms are combined, the upper closing plate is combined, and when the two anti-collision mechanisms are separated, the upper two closing plates are separated.

[0009] A lifting device is installed on the bridge, and a circular fixed part is installed on the lifting device. The lifting device is used to move the entire circular fixed part upward or downward.

[0010] In practical application, the proposed solution allows for the raising or lowering of the overall anti-collision device based on the flood season water level. This ensures that when a vessel veers and collides with the bridge, the anti-collision device is positioned precisely within the collision zone. The advantage of the overall raising design is that it effectively mitigates the impact force during a collision, better protecting the bridge's safety. The circular fixed section, designed to encircle the bridge, can be raised and lowered by the lifting device. The sliding section acts as an indirect force-receiving part after impact. After the impact, the sliding section slides along the circular fixed section to alleviate the impact force, causing the force point to shift and deflect the direct impact force outward. The anti-collision mechanism is the direct impact point. After the impact point is blocked on the two closed plates, the entire anti-collision mechanism first moves radially. When a lateral impact occurs, the arc-shaped anti-collapse plates on both sides rotate during the shift.

[0011] Furthermore, the lifting device includes a limiting slide tube, the drive motor of the limiting slide tube is fixed to the bridge via a mounting base, the output end of the drive motor is fixedly connected to a lead screw, the lead screw is fixed to the bridge via a bearing seat, and a ball bearing sleeve is fitted on the lead screw.

[0012] During the lifting process, the drive motor can be activated when the water level changes. Specifically, when the water level rises or falls, the water level sensor detects the change and controls the drive motor to rotate. This allows the lead screws on the two drive motors to rotate and move the ball bearing sleeves up or down, thus enabling the entire device to move in the vertical direction. This ensures that the circular fixed part and the anti-collision mechanism are lifted as a whole to prevent collisions.

[0013] Furthermore, the circular fixing part includes a circular slide rail arranged vertically, one side of which is fixedly connected to the recycling device, and a guide flipping block is provided on the inner side of the circular slide rail. The guide flipping block is used to limit the sliding part and flip it outward.

[0014] The circular slide rail includes a track and an annular damper. A coil assembly is housed within the annular damper and connected to an external power line. The track effectively controls the trajectory of the sliding plate, and the coil assembly generates magnetic attraction under the influence of an external current. Consequently, the magnetic attraction increases as the sliding plate travels a longer distance, allowing for control over the sliding plate's movement range. Ideally, a return spring can be installed between the sliding plate and the circular slide rail to bring the two sliding plates closer together, aiding in resetting.

[0015] Furthermore, the recycling device is equipped with a winch assembly, which is fixedly connected to the inner side of the sliding part by a pull rope.

[0016] When an impact occurs, the pressure sensor on the anti-collision mechanism receives the pressure data and transmits it to the control terminal. The control terminal then enables the winch assembly inside the recovery device to rotate, allowing the pull rope to be retrieved. During the retrieval of the pull rope, one end of the pull rope is fixedly connected to the side of the sliding plate away from the recovery device. When pulled, as the sliding plate moves to both sides, it can be flipped outwards in conjunction with the guide flipping block, thereby causing the ship to deviate outwards after the impact and correct its navigation. It should be noted that the pressure sensor is located on the outer wall of the arc-shaped anti-collision plate away from the closing plate.

[0017] Furthermore, the sliding part includes a sliding plate, and a hydraulic damping support is provided on one side of the sliding plate in the height direction. A piston rod is provided inside the hydraulic damping support. The piston rod is fixedly connected to the inner wall of the anti-collision mechanism. A limit baffle is provided between the upper and lower hydraulic damping supports. There is a gap between one end of the limit baffle and the anti-collision mechanism, and the length of the limit baffle is greater than the length of the limit baffle.

[0018] The sliding mechanism is designed so that when the impact force directly hits the two closed plates, the arc-shaped anti-crush plate will cause the piston rod to move into the hydraulic damping support. In this way, the piston rod can buffer the impact under the pressure of hydraulic pressure. This can alleviate the impact, and under the action of the limit baffle, the limit baffle can prevent the displacement of the reinforcing rib, thereby increasing the impact force.

[0019] Furthermore, the anti-collision mechanism includes a reinforcing rib, the reinforcing rib being integrally formed with an arc-shaped anti-crush plate, the two arc-shaped anti-crush plates being brought together, and the upper and lower sides of one side of the two arc-shaped anti-crush plates being fixedly connected with a closing plate, and a pressure relief plate being hinged to the outer side of the arc-shaped anti-crush plate, the pressure relief plate being fixedly connected to the outer surface of the sliding plate through an elastic reset assembly.

[0020] The anti-collision mechanism features an arc-shaped anti-collision plate. After a ship impacts, the direct force generated by the impact can be dispersed, creating a component force. This allows the ship to be deflected by the arc-shaped anti-collision plate, thus better guiding the ship away from the anti-collision mechanism and causing it to drift into the river channel. This effectively avoids further impact and, at the same time, corrects the ship's navigation path.

[0021] Furthermore, the elastic reset assembly includes a plate that is elastically rotatably connected to the inner side of the arc-shaped anti-crack plate. An arc-shaped slide rail is provided on the inner side of the plate, and a compression spring is provided in the arc-shaped slide rail. One end of the elastic hinge rod of the elastic reset assembly moves within the arc-shaped slide rail.

[0022] Because ships may collide with the edge of the arc-shaped anti-collision plate, a pressure relief plate is elastically provided on the outer side of the arc-shaped anti-collision plate. When the pressure relief plate is under pressure, the plate on the pressure relief plate rotates, which can eliminate part of the buffer. At the same time, the elastic reset component is compressed by pressure and deformed under the action of the spring. At this time, it can prevent the deflected ship from hitting the bridge, and thus effectively prevent direct impact and prevent ships with collision risk from hitting the bridge.

[0023] The technical effects and advantages of this utility model are as follows:

[0024] 1. The overall anti-collision device can be raised or lowered according to the water level during the flood season. This ensures that when a ship veers off course and collides with the bridge, the anti-collision device is located within the collision area. The advantage of using an overall lifting design is that it can effectively mitigate the impact force when a collision occurs, better protecting the safety of the bridge. The circular fixed part is designed to encircle the bridge and can be raised and lowered by the lifting device. The sliding part acts as an indirect force-receiving part after the impact. After the impact, the sliding part slides on the circular fixed part to mitigate the impact force, causing the force point to shift and the direct impact force to the outside. The anti-collision mechanism is the direct impact point. After the impact point is blocked on the two closed plates, the entire anti-collision mechanism first moves radially. When there is a lateral impact, the arc-shaped anti-collapse plates on both sides will rotate during the shift.

[0025] 2. During the lifting process, the drive motor can be started when the water level changes. Specifically, when the water level rises or falls, the water level sensor detects the change and controls the drive motor to rotate. In this way, the lead screws on the two drive motors can rotate and move the ball bearing sleeve up or down, so that the whole device can move in the vertical direction. This ensures that the circular fixed part and the anti-collision mechanism are lifted as a whole to prevent collisions.

[0026] 3. When an impact occurs, the pressure sensor on the anti-collision mechanism receives the pressure data and transmits it to the control terminal. The control terminal then enables the winch assembly inside the recovery device to rotate, allowing the pull rope to be retrieved. When retrieving the pull rope, one end of the pull rope is fixedly connected to the side of the sliding plate away from the recovery device. When pulled, as the sliding plate moves to both sides, it can be flipped outwards in conjunction with the guide flipping block, thereby causing the ship to deviate outwards after the impact and correct its navigation.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 4 The bridge collision avoidance device shown includes:

[0034] The circular fixing part is fixed to the bridge and used to install the overall structure;

[0035] The sliding part is set on the circular fixed part and is pulled and slid by the recycling device 3 fixedly connected to the circular fixed part. The sliding part includes a sliding plate 6, and a hydraulic damping support 7 is set on one side of the sliding plate 6 in the height direction. A piston rod 71 is set inside the hydraulic damping support 7. The piston rod 71 is fixedly connected to the inner wall of the anti-collision mechanism. A limit baffle 8 is set between the upper and lower hydraulic damping supports 7. There is a gap between one end of the limit baffle 8 and the anti-collision mechanism, and the length of the limit baffle 8 is greater than the length of the limit baffle 8.

[0036] The sliding part is designed so that when the impact force directly hits the two closed plates 10, the arc-shaped anti-crush plate 9 will cause the piston rod 71 to move into the hydraulic damping support 7. In this way, the piston rod 71 can buffer the impact under the action of pressure, which is hydraulic pressure. This can alleviate the impact. At the same time, under the action of the limiting baffle 8, the limiting baffle 8 can prevent the stiffener 11 from displacing, thereby increasing the impact force.

[0037] The anti-collision mechanism has two parts, which are located on one side of the sliding part. When the two anti-collision mechanisms are combined, the upper closing plate 10 is combined. When the two anti-collision mechanisms are separated, the upper two closing plates 10 are separated. The anti-collision mechanism includes a reinforcing rib 11, and the reinforcing rib 11 is integrally formed with an arc-shaped anti-crush plate 9. The two arc-shaped anti-crush plates 9 are close together, and the upper and lower sides of one side of the two arc-shaped anti-crush plates 9 are fixedly connected with closing plates 10. A pressure relief plate 91 is hinged to the outer side of the arc-shaped anti-crush plate 9. The pressure relief plate 91 is fixedly connected to the outer surface of the sliding plate 6 through an elastic reset component 13. A bottom support 1 is provided at the bottom of the arc-shaped anti-crush plate 9.

[0038] The anti-collision mechanism is designed with an arc-shaped anti-collision plate 9. After a ship collision, the direct force generated by the impact can be dispersed, resulting in a component force. This allows the ship to be deflected by the arc-shaped anti-collision plate 9, thus better deflecting the ship into the river channel after it hits the anti-collision mechanism. This effectively avoids further impact and at the same time corrects the ship's navigation path.

[0039] A lifting device is installed on the bridge. A circular fixed part is installed on the lifting device. The lifting device is used to move the entire circular fixed part up or down. The lifting device includes a limiting slide tube 5. The drive motor 51 of the limiting slide tube 5 is fixed on the bridge by a mounting base. The output end of the drive motor 51 is fixedly connected to a lead screw 52. The lead screw 52 is fixed on the bridge by a bearing seat. A ball sleeve is fitted on the lead screw 52.

[0040] During the lifting process, the drive motor 51 can be started when the water level changes. Specifically, when the water level rises or falls, the water level sensor detects the change and controls the drive motor 51 to rotate. In this way, the lead screw 52 on the two drive motors 51 can rotate and move the ball sleeve up or down, so that the whole device can move in the vertical direction. This ensures that the circular fixed part and the anti-collision mechanism are lifted as a whole to prevent collisions.

[0041] In practical use, the proposed solution allows for the raising or lowering of the overall anti-collision device based on the flood season water level. This ensures that when a ship veers off course and collides with the bridge, the anti-collision device is positioned precisely within the collision zone. The advantage of the overall raising design is that it effectively mitigates the impact force during a collision, better protecting the bridge's safety. The circular fixed part, designed to encircle the bridge, can be raised and lowered by the lifting device. The sliding part acts as an indirect force-receiving part after impact. After the impact, the sliding part slides along the circular fixed part to mitigate the impact force, causing the force point to shift and the direct impact force to the outward. The anti-collision mechanism is the direct impact point. After the impact point is on the two closed plates 10, the entire anti-collision mechanism first moves radially. When a lateral impact occurs, the arc-shaped anti-collapse plates 9 on both sides will rotate during the shift.

[0042] The circular fixed part includes a circular slide rail 2 arranged vertically. A recycling device 3 is fixedly connected to one side of the circular slide rail 2. A guide flipping block 12 is provided on the inner side of the circular slide rail 2. The guide flipping block 12 is used to limit the sliding part and make it flip outward.

[0043] The circular slide rail 2 includes a track 21 and an annular damper 22. A coil assembly is installed inside the annular damper 22 and is connected to an external wire. The track 21 effectively controls the trajectory of the sliding plate 6, and the coil assembly generates a magnetic attraction force under the action of an external current. As the sliding plate 6 moves a longer distance, the magnetic attraction force becomes stronger, thereby controlling the range of movement of the sliding plate 6. Optimally, a return spring can also be installed between the sliding plate 6 and the circular slide rail 2 to bring the two sliding plates 6 closer together and aid in resetting.

[0044] The recovery device 3 is equipped with a winch assembly, which is fixedly connected to the inside of the sliding part by a pull rope 4.

[0045] When an impact occurs, the pressure sensor on the anti-collision mechanism receives the pressure data and transmits it to the control terminal. The control terminal causes the winch assembly in the recovery device 3 to rotate, which enables the pull rope 4 to be retrieved. When retrieving the pull rope 4, one end of the pull rope 4 is fixedly connected to the side of the sliding plate 6 away from the recovery device 3. When pulled, when the sliding plate 6 moves to both sides, it can be flipped outward with the help of the guide flipping block 12, thereby causing the ship to deviate outward after the impact and correct its navigation. It should be noted that the pressure sensor is set on the outer wall of the arc-shaped anti-collision plate 9 away from the closing plate 10.

[0046] The elastic reset assembly 13 includes a plate that is elastically rotatably connected to the inner side of the arc-shaped anti-crack plate 9. An arc-shaped slide rail is provided on the inner side of the plate, and a compression spring is provided in the arc-shaped slide rail. One end of the elastic hinge rod of the elastic reset assembly 13 moves in the arc-shaped slide rail.

[0047] In the above embodiment, since a ship may collide with the edge of the arc-shaped anti-collision plate 9, a pressure relief plate 91 is elastically provided on the outer side of the arc-shaped anti-collision plate 9. When the pressure relief plate 91 is under pressure, the plate on the pressure relief plate 91 rotates, which can eliminate part of the buffer. At the same time, the elastic reset component 13 is compressed by pressure and deformed under the action of the spring. At this time, it can prevent the deflected ship from colliding with the bridge, thereby effectively preventing direct collision and preventing ships with collision risk from colliding with the bridge.
