Description

Technical Field

[0001] The present invention relates to the technical field of bridge anti-collision detection technology, and in particular to an integrated bridge anti-collision detection device. Background Art

[0002] Bridges, especially those built on rivers, generally need to be equipped with anti-collision devices on the piers to protect the piers and passing ships, so as to reduce the damage caused by ships to the piers.

[0003] Existing anti-collision devices generally use materials or structures with buffering functions and are attached to bridge piers for use. After passing ships collide with the bridge piers, the anti-collision devices buffer the impact force and absorb energy, thereby reducing the impact on the bridge piers and ships. However, when the impact force is large and exceeds the design limit of the anti-collision device, it will still cause certain damage to the bridge piers. Since the anti-collision device is installed in close contact with the bridge piers, the anti-collision device needs to be removed at this time before the bridge piers can be inspected to check the extent of damage to the collision part of the bridge piers. Therefore, it is not convenient for the inspection of the bridge piers and is not convenient and quick to use.

[0004] Therefore, it is necessary to provide an integrated bridge anti-collision detection device to solve the above technical problems. Summary of the Invention

DETAILED DESCRIPTION

[0033] The present invention will be further described below with reference to the accompanying drawings and examples. The embodiments of the present invention include but are not limited to the following examples.

[0034] Example 1:

[0035] like Figure 1-8As shown, the bridge anti-collision detection integrated device provided by the present invention includes: a fixing mechanism, an early warning mechanism, an anti-collision mechanism and a detection mechanism; the fixing mechanism is used to fix the entire device to the bottom of the bridge for use. In this embodiment, the fixing mechanism includes two half-tubes connected into one by bolts, and the two half-tubes are buckled into a whole fixed tube 1, and the fixed tube 1 is sleeved on the bridge pier for use, and the top of the fixed tube 1 is connected to the bottom of the bridge. In this embodiment, bolts are used to connect and fix the fixed tube 1 to the crossbeam at the bottom of the bridge; the early warning mechanism includes a first gear ring 5 rotatably mounted on the fixed tube 1, and a plurality of first support plates 6 are installed on the first gear ring 5. The first support plates 6 face A first camera 2 is installed on the outer side, and the first camera 2 is wirelessly connected to the main control end. When the ship enters the shooting range of the first camera 2, the image recorded by the first camera 2 is transmitted back to the main control end. When the ship is close to the dangerous area of the bridge pier (the area is artificially divided around the bridge pier), the main control end automatically issues an alarm. The staff can observe the driving trajectory of the hull through the image transmitted by the first camera 2, and then determine whether to start the anti-collision system and make the anti-collision mechanism take corresponding action; the anti-collision mechanism includes a second gear ring 7 rotatably mounted on the fixed tube 1. The second gear ring 7 has a similar structure to the first gear ring 5. Both are assembled with two half gear rings. The first gear ring The radius of the ring 5 is smaller than the radius of the second gear ring 7. Two second support plates 11 are symmetrically installed at the bottom of the second gear ring 7. A first electric push rod 24 is installed at the bottom of the second support plate 11. An arc plate 12 is installed at the bottom end of the first electric push rod 24. Two rubber anti-collision plates 3 are installed between the two arc plates 12. The two arc plates 12 and the two anti-collision plates 3 are sleeved around the bridge pier, and the arc plates 12 and the anti-collision plates 3 maintain a sufficient distance from the bridge pier, which is convenient for the detection mechanism to detect the bridge pier. A second drive component is set on the fixed pipe 1. The second drive component is wirelessly connected to the main control end. The main control end controls the start and stop of the second drive component, thereby driving The second gear ring 7 rotates to adjust the direction of the anti-collision plate 3. When the ship approaches the pier, the staff controls the second drive assembly to start, so that the second gear ring 7 rotates, and then the second support plate 11 rotates. As a result, the bottom anti-collision plate 3 rotates to face the direction of the ship. In addition, the first electric push rod 24 is controlled by the main control end to start and adjust the height of the anti-collision plate 3 to better prepare for the upcoming collision. When the ship hits the anti-collision plate 3, the anti-collision plate 3 absorbs energy by deformation, reducing damage to the pier and the ship. After the collision, the anti-collision plate 3 recovers its shape due to its own stress, and then the functional detection mechanism can be used to detect the impact site.The detection mechanism includes a detection bracket 4, on which a detector 25, a second camera 26 and a fill light 27 are installed. In this embodiment, the detection bracket 4 is connected to the first support plate 6 through a second electric push rod 13, and a first drive assembly is installed on the fixed tube 1. The first drive assembly is used to drive the first ring gear 5 to rotate. After the collision occurs, the main control end controls the second electric push rod 13 to start, so that the detection bracket 4 descends, and then the detector 25 and the second camera 26 are extended into the gap between the anti-collision plate 3 and the bridge pier. Then the main control end controls the first drive assembly The component is activated, causing the first ring gear 5 to rotate, causing the detector 25 and second camera 26 to rotate horizontally, facilitating detection of the impact site. While the detector 25 detects the bridge pier, the fill light 27 illuminates the bridge pier to improve visibility. The second camera 26 transmits the captured image of the bridge pier back to the main control terminal, facilitating adjustments to the inspection site, thereby completing the bridge pier inspection. After the inspection is completed, the output end of the second electric push rod 13 shortens and resets, causing the detector 25, second camera 26, and fill light 27 to rise and reset to a relatively safe height.

[0036] By setting up a fixing mechanism, an early warning mechanism, an anti-collision mechanism and a detection mechanism, the anti-collision and detection are integrated into a design, and the anti-collision plate 3 that is not installed close to the bridge pier is used to absorb the energy of the ship's impact, thereby reducing the damage to the bridge pier caused by the impact. After the collision occurs, the damaged part of the bridge pier can be detected without removing the anti-collision mechanism, which is more convenient and quick to use.

[0037] Example 2:

[0038] like Figure 3-4 As shown, in this embodiment, the detection bracket 4 is fixedly connected to one of the curved plates 12. After an impact occurs, the first electric push rod 24 and the second drive assembly drive the curved plate 12 to descend and rotate horizontally, thereby controlling the descent and rotation of the detection bracket 4. This, in turn, drives the detector 25 and the second camera 26 to descend and rotate, thereby inspecting the impact site on the bridge pier. This solution eliminates the first drive assembly and the second electric push rod 13, resulting in lower costs.

[0039] By arranging the bracket to be connected with the corresponding arc-shaped plate 12, the cost can be reduced while the detection machine can be driven to perform detection.

[0040] Example 3:

[0041] like Figure 1-2As shown, the first drive assembly includes a first drive bracket 8 installed on the fixed tube 1, and the first drive bracket 8 is installed with a first drive motor 9. The first drive motor 9 is wirelessly connected to the general control end. In this embodiment, Bluetooth can be used for connection and communication. A first gear 10 is installed on the output shaft of the first drive motor 9, and the first gear 10 is engaged with the first ring gear 5. When in use, the general control end controls the first drive motor 9 to start, thereby rotating the first gear 10 and the first ring gear 5 engaged therewith, so that the first camera 2 and the detection mechanism installed below the first ring gear 5 are rotated horizontally, adjusting the shooting direction of the first camera 2 and the detection direction of the detection mechanism.

[0042] By providing the first driving bracket 8, the first driving motor 9 and the first gear 10, the first ring gear 5 can be conveniently rotated horizontally, thereby adjusting the shooting direction of the first camera 2 and the detection direction of the detection mechanism.

[0043] Example 4:

[0044] like Figure 1-2 As shown, the second drive assembly includes a second drive bracket 14 installed on the fixed pipe 1, and a second drive motor 15 is installed on the second drive bracket 14. The second drive motor 15 is connected to the main control end by Bluetooth wireless. The output shaft of the second drive motor 15 is installed with a second gear 16, and the second gear 16 is engaged with the second ring gear 7. When in use, similar to Example 3, the main control end controls the second drive motor 15 to start, and then drives the second ring gear 7 to rotate through the second gear 16, thereby adjusting the direction of the anti-collision plate 3 below to face the ship.

[0045] By providing the second driving bracket 14 , the second driving motor 15 and the second gear 16 , the second ring gear 7 can be conveniently driven to rotate horizontally.

[0046] Example 5:

[0047] like Figure 5As shown, a slide groove 18 is provided on the curved plate 12, and guide plates 19 adapted to the slide groove 18 are installed at both ends of the anti-collision plate 3. The guide plates 19 are slidably installed in the slide groove 18, and an arc-shaped guide rod 21 is installed between the two guide plates 19 close to each other. A spring 22, two limit plates 20 and a nut are installed on the guide rod 21, wherein the curvature of the guide rod 21 is consistent with the curvature of the slide groove 18, and the guide rod 21 passes through the slide groove 18. Tighten the nuts at both ends of the guide rod 21 so that the limit plates 20 are pressed tightly against the outlets at both ends of the slide groove 18, thereby making the guide The rod 21 is fixed in the chute 18, and the guide rod 21 passes through the guide plate 19. Therefore, when a ship collides with the collision plate 3, the collision plate 3 is squeezed, causing the guide plate 19 at the end of the collision plate 3 to slide in the chute 18 along the bending direction of the chute 18 (guide rod 21), thereby compressing the spring 22. The first stage of energy absorption is carried out through the deformation of the spring 22, and then the collision plate 3 collides with the bridge pier, causing the collision plate 3 to deform and absorb energy in the second stage. After the collision, the spring 22 is reset, and the collision plate 3 moves outward and resets, so that the collision plate 3 is out of contact with the bridge pier.

[0048] By providing the slide groove 18, the guide plate 19, the limit plate 20, the guide rod 21 and the spring 22, a certain energy of the collision can be absorbed, the anti-collision ability of the device is improved, and the anti-collision plate 3 can be easily disassembled and replaced.

[0049] Example 6:

[0050] like Figure 6 As shown, a plurality of suction cups 23 are installed on the top of the fixed tube 1. The suction cups 23 are adsorbed on the bottom of the bridge (such as a beam), thereby fixing the fixed tube 1 on the bridge pier for use. It is worth noting that in this embodiment, the suction cups 23 are connected to the air pump through a pipeline. The air pump can be fixed on the top of the fixed tube 1. The air pump extracts the air in the suction cups 23 to create a negative pressure inside the suction cups 23, and a pressure sensor is installed in the pipeline or the suction cups 23. The pressure sensor and the air pump are both connected to the main control end. When the suction cups 23 leak and the air pressure increases, the pressure sensor transmits the data back to the main control end. The main control end controls the start of the air pump according to the pressure change to continue to extract the air in the suction cups 23 so that the suction cups 23 can be stably adsorbed on the bottom of the bridge.

[0051] By installing the suction cup 23 on the top of the fixing pipe 1, the fixing pipe 1 can be conveniently fixed on the bridge pier for use.

[0052] Example 7:

[0053] like Figure 4As shown, this embodiment is used in conjunction with embodiment 2. In this embodiment, the first gear ring 5 and the second gear ring 7 are connected by a special-shaped plate 17. When in use, the first gear ring 5 and the second gear ring 7 rotate synchronously. Therefore, when the second gear ring 7 rotates, the first gear ring 5 rotates, so that the shooting direction of the first camera 2 below the first gear ring is consistent with the direction of the anti-collision plate 3, which facilitates the anti-collision plate 3 to be aligned with the ship.

[0054] By setting, the special-shaped plate 17 is installed between the first gear ring 5 and the second gear ring 7, so that the first gear ring 5 and the second gear ring 7 can rotate synchronously, making it easier to align the anti-collision plate 3 with the ship.

[0055] Working principle: When in use, the fixed tube 1 is connected and fixed to the crossbeam at the bottom of the bridge. When the ship is close to the dangerous area of the bridge pier, the main control terminal will issue an alarm. The staff can observe the trajectory of the hull through the image transmitted by the first camera 2, and then determine whether to activate the anti-collision system and make the anti-collision mechanism take corresponding actions;

[0056] When the ship approaches the pier, the staff controls the second drive assembly to start, so that the second gear ring 7 rotates, and then the second support plate 11 rotates, so that the bottom anti-collision plate 3 rotates to face the direction of the ship, and the first electric push rod 24 is controlled by the main control end to start, so as to adjust the height of the anti-collision plate 3 to better prepare for the upcoming collision. When the ship hits the anti-collision plate 3, the anti-collision plate 3 absorbs energy by deformation, reducing damage to the pier and the ship. After the collision, the anti-collision plate 3 recovers, and then the functional detection mechanism can be used to detect the impact site;

[0057] After the collision occurs, the main control end controls the second electric push rod 13 to start, so that the detection bracket 4 drops, and then the detector 25 and the second camera 26 are extended into the gap between the anti-collision plate 3 and the bridge pier. Then the main control end controls the first drive component to start, so that the first ring gear 5 rotates, and the detector 25 and the second camera 26 rotate horizontally, so as to facilitate the detection of the collision part. While the detector 25 detects the bridge pier, the fill light 27 illuminates the bridge pier to improve the clarity of the line of sight. The detector 25 transmits the data back to the main control end, and the second camera 26 transmits the captured image of the bridge pier back to the main control end, so that the staff can adjust the detection part and complete the bridge pier detection. After the detection is completed, the output end of the second electric push rod 13 shortens and resets, so that the detector 25, the second camera 26, and the fill light 27 rise and reset, and return to a relatively safe height.
