Description

Technical Field

[0001] The utility model belongs to the technical field of bridge anti-collision interception facilities, and in particular relates to a mobile interception device for out-of-control ships. Background Art

[0002] With the rapid development of my country's transportation industry, inland waterway and sea routes are becoming increasingly mature, and the ships passing through have a tendency to increase in tonnage and speed; on the other hand, there are more and more cross-river and cross-sea bridges. The passage of ships will be affected by objective factors such as weather, water conditions, and the ship's own working conditions. Studies have shown that human factors such as improper operation and misjudgment are the main reasons for ships to lose control and collide with bridges. At present, the existing active collision avoidance technology cannot prevent out-of-control ships from colliding with bridges, and passive collision avoidance technology often uses physical interception devices in the collision avoidance application of non-navigable holes of bridges. The interception length is often very long, and there are problems such as high construction cost and difficult maintenance and restoration.

[0003] The Chinese invention patent with patent publication number CN105544439A and publication date 2023.10.10 discloses a movable ship interception method for a long bridge, including two independently controlled automatic control mobile floating boats, an interception rope or interception net is fixedly arranged between the two automatic control mobile floating boats, and an automatic winding mechanism is installed on each of the automatic control mobile floating boats, and a gravity anchor is connected to the automatic winding mechanism, and the gravity anchor is sunk to the bottom of the water so that the automatic control mobile floating boat can be fixed on the water surface; a monitoring system and an alarm are installed on the long bridge, and the monitoring system monitors the course, speed and position of the ship in real time; if the ship deviates from the channel, the control system controls the automatic winding mechanism to retract the gravity anchor, and controls the automatic control mobile floating boat to move to the required interception position in time according to the monitored course, speed and position of the ship. When the automatic control mobile floating boat moves into place, the control system controls the automatic winding mechanism to lower the gravity anchor to fix the automatic control mobile floating boat to intercept the ship.

[0004] The Chinese invention patent discloses a movable ship interception method for a long bridge, and its general usage and advantages are as follows: the monitoring system monitors the ship's heading, speed and position in real time. When the monitoring system detects that the ship deviates from the waterway, the monitored ship heading, speed and position are sent to the control system, and the control system controls the alarm to sound an alarm. If the ship continues to deviate from the waterway, the control system controls the movable ship interception device to move to the required interception position in time to intercept the ship. The advantage is that it can effectively intercept the ship without installing a large interception device in front of the non-navigable hole of the long bridge, which greatly reduces the cost, and the installation and transportation are very convenient and simple, and the maneuverability is strong.

[0005] However, in actual use, the interception device still has at least the following shortcomings, in other words, which are the technical problems to be solved by the present invention: the interception device does not disclose a specific interception net structure, the ordinary interception net can target a very limited number of ships, and the interception net is easily damaged or the interception fails due to strong impact force.

[0006] Therefore, in summary, there is an urgent need for a durable interception device that can cope with a variety of situations to solve the problems of this type. Utility Model Content

[0029] Embodiment 1

[0030] As attached Figure 1-3 As shown, a mobile device for intercepting an out-of-control ship comprises a mobile platform 1 arranged on the water surface, two floating support units 2 relatively arranged on the mobile platform 1, a first blocking net 3 and a second blocking net 4 arranged between the two floating support units 2 and parallel to each other; the tensioning degree of the second blocking net 4 is greater than that of the first blocking net 3.

[0031] In this embodiment, the general method of using the mobile interception device for out-of-control ships is as follows:

[0032] The mobile platform 1 moves in the restricted navigation zone on both sides of the non-navigable hole of the bridge. An active monitoring and control system is arranged on the bridge, including: monitoring equipment arranged on the bridge for monitoring the heading and speed of the ship, early warning equipment arranged on the bridge, and a central intelligent controller which is connected to the monitoring equipment and the early warning equipment in communication and is used to control the movement of the mobile platform; the monitoring equipment divides the monitoring range into a tracking zone, a warning zone and a restricted navigation zone. The tracking zone mainly identifies information such as the type, speed and position of the ship, the warning zone monitors whether the ship is traveling according to the expected track, and the restricted navigation zone monitors whether the mobile platform 1 intercepts the out-of-control ship; the early warning device is used to send early warning information to the controllable ship that has mistakenly entered the tracking zone, and guides The controllable ship sails towards the navigable area; the central intelligent controller is used to calculate the future track of the out-of-control ship and control the mobile platform 1 to intercept at the designated location; in actual use, when the ship enters the tracking area, the monitoring equipment transmits the identification information to the central intelligent controller, and the early warning device sends an early warning message to the ship that mistakenly enters the tracking area. If the ship that receives the early warning message sails towards the navigable area, the mobile platform 1 does not need to be dispatched. If the ship that receives the early warning message sails towards the warning area according to the expected track, the central intelligent controller controls the mobile platform 1 to carry the interception device to the designated location and release it, so that the interception device can intercept the out-of-control ship. During the interception process, the first blocking net 3 and the second blocking net 4 consume the ship's energy by intercepting the hull.

[0033] It is worth noting that the above-mentioned monitoring equipment, early warning equipment, central intelligent controller, etc. are all known technologies to those skilled in the art, so they will not be described in detail in this embodiment.

[0034] The interception device is arranged on a mobile platform 1, and includes a floating support unit 2 that enables the device to float on the water surface. The first blocking net 3 and the second blocking net 4 are respectively connected to the two floating support units 2 at both ends, wherein the first blocking net 3 is located on the facing surface of the out-of-control ship, and the second blocking net 4 is located parallel to the rear side of the first blocking net 3, wherein the tension of the second blocking net 4 is greater than that of the first blocking net 3 to ensure that the second blocking net 4 provides a stronger interception resistance force. After the first blocking net 3 consumes the impact force of the ship in a relatively gentle way of intercepting the ship, the second blocking net 4 intercepts the ship with a higher tension, thereby avoiding direct confrontation with the ship and causing damage to the blocking net.

[0035] As a preferred embodiment of the present embodiment, the floating support unit 2 includes a fixing frame 21, a first connecting plate 22 arranged on one side of the fixing frame 21 and used to fix the end of the first blocking net 3, a second connecting plate 23 rotatably connected to the other side of the fixing frame 21 and used to fix the end of the second blocking net 4, a trigger structure 24 for driving the second connecting plate 23 to rotate to tension the second blocking net 4, a buoy 25 arranged on the first blocking net 3 and the second blocking net 4, a limiting buoy rod 26 respectively arranged on the first blocking net 3 and the second blocking net 4 and located between two adjacent buoys 25, a telescopic rope 28 arranged on the fixing frame 21 and connected to the mobile platform 1, an anchor 29 arranged at the lower end of the fixing frame 21, and reflective strips are arranged on the buoy 25 and the limiting buoy rod 26.

[0036] In this embodiment, by setting a trigger mechanism 24, the tension of the second net 4 can be adapted according to the actual situation, and there is no need to pre-set the tension of the two nets, which is more flexible when used. By setting the float 25 and the limit float rod 26 on the upper ends of the first net 3 and the second net 4, the device floats on the water surface. Preferably, the float 25 and the limit float rod 26 are rotatably connected to the first net 3 and the second net 4 for easy movement. It is further preferred that the float 25 and the limit float rod 26 are staggered to effectively prevent the nets from being entangled and facilitate deployment; by adjusting the telescopic rope 28 set on the motorized platform 1 to a suitable length, the telescopic rope 28 and the fixed frame 21 are placed in the water, and the net and the fixed frame 21 are floated by the float 25 and the limit float rod 26. The two ends of the fixed frame 21 are respectively connected to the first connecting plate 22 and the second connecting plate 23, wherein the first connecting plate 22 and the fixed frame 21 are connected to the first connecting plate 22 and the fixed frame 21. The second connecting plate 23 is fixedly connected and rotatably connected to the fixing frame 21. The trigger structure 24 is arranged on the second connecting plate 23. When the first blocking net 3 is deformed to a certain limit under the action of the ship, the hull drives the first blocking net 3 to act on the trigger mechanism 24 to drive the rotation of the second connecting plate 23, thereby tensioning the second blocking net 4 to provide a stronger counterforce. The reflective strip is arranged on the buoy 25 and the limiting float rod 26 to facilitate the observation of the deployment of the blocking net. The anchor 29 is arranged at the lower end of the fixing frame 21. It is preferred to use a retractable rope or a winding mechanism to connect the fixing frame 21 and the anchor 29. On the one hand, the position of the entire interception device is fixed. On the other hand, if the energy of the ship is large, the anchor can be driven to consume the energy of the ship by dragging the anchor.

[0037] As a preferred embodiment of the present embodiment, the trigger structure 24 includes a first trigger rod 241 disposed on the second connecting plate 23 , and a first return torsion spring 242 disposed at the connection between the fixing frame 21 and the second connecting plate 23 .

[0038] In this embodiment, the first trigger rod 241 is arranged between the first blocking net 3 and the second blocking net 4, one end of which is connected to the second connecting plate 23 and the other end is facing the direction relative to the other second connecting plate 23. It is preferably arranged perpendicular to the second connecting plate 23, and the angle of the first trigger rod 241 can also be set according to actual conditions. The smaller the angle formed by the first trigger rod 241 and the second connecting plate 23, the smaller the tension of the second blocking net 4 can be driven; the fixing frame 21 is preferably shaft-shaped, and the first reset torsion spring 242 is connected between the fixing frame 21 and the second connecting plate 23. When the ship is successfully intercepted, the first trigger rod 241 loses the external force, and under the action of the first reset torsion spring 242, the second connecting plate 23 is driven to restore to its initial state, thereby avoiding the second blocking net 4 always remaining in a highly tensioned state and reducing its service life.

[0039] As a preference of this embodiment, the first trigger rod 241 is an externally threaded rod, and the trigger structure 24 includes a first extension rod 248 threadedly disposed on the first trigger rod 241 .

[0040] In this embodiment, in order to accommodate out-of-control ships of various sizes, the first trigger rod 241 is set as an externally threaded rod, and the first extension rod 248 is a hollow rod with an internal thread matching the external thread of the first trigger rod 241. The length of the overall structure of the two rods can be adjusted by rotation to accommodate different ships.

[0041] Compared with the prior art, the advantages of this embodiment are: the coordinated design of the double-layer intercepting net makes the intercepting net have different functions. While effectively intercepting out-of-control ships, the structure can also avoid damage to the intercepting net caused by strong impact. Furthermore, a linked trigger mechanism is arranged between the double-layer intercepting nets, so that the tensioning degree of the second layer of intercepting net can be adapted according to actual conditions, and when the first layer of intercepting net is damaged and cannot be replaced in time, the second layer of intercepting net can also play an intercepting role in emergency situations by changing direction.

[0042] Embodiment 2

[0043] As attached Figure 4-5 As shown, the difference between this embodiment and the first embodiment is that another trigger structure 24 is disclosed, which is as follows:

[0044] The trigger structure 24 includes a fixed rod 243 arranged on the fixed frame 21, a second trigger rod 244 rotatably arranged on the fixed rod 243, a second return torsion spring 245 arranged at the connection between the fixed rod 243 and the second trigger rod 244, a fixed pulley 246 arranged on the side of the fixed frame 21 away from the second connecting plate 23, and a connecting rope 247 with one end connected to the second connecting plate 23 and the other end wound around the fixed pulley 246 and connected to the second trigger rod 244.

[0045] In this embodiment, the first connecting plate 22 is fixedly connected to one end of the fixing frame 21, and a fixing rod 243 is arranged in the fixing frame 21. One end of the second trigger rod 244 is arranged in a sleeve shape, which is connected to the fixing rod 243 by rotation, and passes through the slots arranged on the opposite sides of the two fixing frames 21 to be exposed outside the fixing frame 21, so that the second trigger rod 244 can effectively contact the ship; the second reset torsion spring 245 is arranged between the sleeve ends of the fixing rod 243 and the second trigger rod 244 to drive the reset of the second connecting plate 23; a fixed pulley 246 is arranged on one side of the fixing frame 21 close to the first connecting plate 22, and the fixed pulley 246 is connected to the fixing frame 21 through a fixed shaft and is prevented from moving in the vertical direction by a limit block, preferably, the fixed pulley 246 and the second The trigger rod 244 is located at the same height and is more convenient for transmission; one end of the connecting rope 247 is connected to the second trigger rod 244, and the other end passes through the fixed pulley 246 and is connected to the second connecting plate 23 arranged on the side away from the first connecting plate 22. One end of the second connecting plate 23 is fixed to the inside of the fixing frame 21 by a hinge, and the other end passes through the slot on the side of the fixing frame close to the second blocking net 4 and extends outward. In order to optimize the force effect, a pulley can be further provided in the fixing frame 21 on the basis of the fixed pulley 246; the ship pushes the second trigger rod 244 to drive the connecting rope 247 to pull the second connecting plate 23 to rotate to the outside away from the other second connecting plate 23, thereby tensioning the second blocking net 4. When the ship separates from the second trigger rod 244, the second trigger rod 244 automatically returns to its initial state and drives the second connecting plate 23 to return.

[0046] As a preferred embodiment of this embodiment, the second trigger rod 244 is an external thread rod, and the trigger structure 24 includes a second extension rod 249 threadedly arranged on the second trigger rod 244. The second extension rod 249 is a hollow rod with an internal thread matching the external thread of the second trigger rod 244, and the overall length can be adjusted by rotation to adapt to different ships.

[0047] Compared with the prior art, the advantages of this embodiment are: it avoids relying on a simple reset torsion spring to bear the force, and utilizes the transmission structure to ensure that the trigger rod is located in the middle position of the opposite sides of the double-layer blocking net on the one hand, and on the other hand, shares the pressure of the single axis and the torsion spring, thereby extending the service life of the entire device.

[0048] Embodiment 3

[0049] As attached Figure 2 , Attachment Figure 4 As shown, the difference between this embodiment and the first and second embodiments is that a limiting structure is added to prevent the blocking net from being retracted inwards to avoid the blocking net from failing, as follows:

[0050] The floating support unit 2 further includes a limiting plate 27 disposed on the fixing frame 21 and used for limiting the second connecting plate 23 from rotating toward another second connecting plate 23 .

[0051] In this embodiment, to prevent the two second connecting plates 23 from rotating to the opposite side under the influence of external forces, the limit plates 27 are fixedly connected to the fixing frame 21 and are respectively located on the opposite inner sides of the two second connecting plates 23, and the angle can be slightly tilted by 10 degrees as a movable space.

[0052] Compared with the prior art, the advantage of this embodiment is that when the first blocking net fails, the second blocking net is turned around and used temporarily to intercept the ship's front surface. In order to avoid the second blocking net shrinking inwards and causing interception failure, a limit plate is provided to ensure the normal deployment of the second blocking net.

[0053] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
