Description

Technical Field

[0001] This utility model relates to the field of port defense, and in particular to a port defense system. Background Technology

[0002] Intercepting and providing early warning of intruding objects or organisms into a port is a crucial measure for ensuring port security. To achieve this, existing port access channels require port defense systems. The core technology involves suspending a fiber optic defense network in the port's access channels when no vessels are passing through. This network intercepts and provides early warning of intruding objects or organisms. After the fiber optic defense network is removed, the port access channels are reopened to allow vessels to pass. However, existing fiber optic defense systems do not consider how to balance the fixed height of the fiber optic defense network with its adaptability to changes in water level. Specifically, due to the influence of tides, the water level in the port's access channels is constantly changing. If the height of the fiber optic defense network, suspended in the port's access channels, cannot be adjusted, both rising and falling water levels will place a significant burden on the main cable, traction winch, channel walls, and network components used to pull the network. Specifically, the greater the water level drop, the greater the tension or burden on the main cable and traction winch. If the height of the fiber optic defense network is not fixed, it will constantly change with the water level, causing the main cable to slack. This could lead to collisions between the network's pontoons and channel walls in large waves, resulting in safety hazards. Furthermore, the swaying of the network will cause significant wear on the steel cables. Therefore, how to balance a fixed fiber optic defense network height with its adaptive height to changes in water level is the technical problem that the inventors of this invention are committed to solving. Utility Model Content

[0003] One objective of this invention is to provide a port defense system in which, when the water level in the port's entrance and exit channels does not change significantly, the height of the fiber optic defense network remains constant; and when the water level in the port's entrance and exit channels changes significantly, the height of the fiber optic defense network adapts to the water level changes. In this way, the port defense system can have a smaller workload, which is beneficial to ensuring the stability and reliability of the port defense system.

[0004] One objective of this invention is to provide a port defense system, wherein the environmental monitoring device of the port defense system constantly monitors changes in the water surface to provide data support for the port defense system to adjust the height of the fiber optic defense network.

Secondly, the term "a" should be understood as "at least one" or "one or more," that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple. The term "a" should not be construed as a limitation on the quantity.

[0035] Refer to the accompanying drawings of the specification of this utility model. Figures 1 to 10D A preferred embodiment of the present invention will be disclosed and described in the following description, wherein the port defense system includes a main cable 10, a fiber optic defense network 20, two horizontal traction winches 30, two bank base guide wheels 40, two environmental monitoring devices 50, a plurality of flexible connecting ropes 60, a plurality of buoy devices 70, and two height adjustment devices 80.

[0036] Specifically, the two height adjustment devices 80 are respectively installed on opposite sides of the port access channel 1000. A shore-based guide wheel 40, a horizontal traction winch 30, and an environmental monitoring device 50 are respectively installed on the outer side of each of the two height adjustment devices 80. One end of the main cable 10 is operably connected to the horizontal traction winch 30 after sequentially passing over a pulley assembly 81 of one of the height adjustment devices 80 and a shore-based guide wheel 40. The other end of the main cable 10 passes sequentially over the pulley assembly 81 of the other height adjustment device 80. The pontoon device 70 is operably connected to another horizontal traction winch 30 after another shore-based guide wheel 40. Each of the pontoon devices 70 is spaced apart from each other on the top of the fiber optic defense network 20. Adjacent pontoon devices 70 are connected by the flexible connecting rope 60. One of the pontoon devices 70 at one end remains in a fixed position relative to a height adjustment device 80. The pontoon device 70 at the other end is fixedly connected to the main cable 10. The remaining pontoon devices 70 are slidably connected to the main cable 10.

[0037] In the attached Figure 1In this typical example of the port defense system shown, concrete foundations are constructed on opposite sides of the port access channel 1000. For ease of illustration, one of the two concrete foundations is defined as the left foundation, and the other as the right foundation. A horizontal traction winch 30 is located at the top of the left foundation, a shore-based guide wheel 40 and an environmental monitoring device 50 are located at the top and inner corner of the left foundation, and a height adjustment device 80 is located adjacent to the left foundation. Another horizontal traction winch 30 is located at the top of the right foundation, another shore-based guide wheel 40 and another environmental monitoring device 50 are located at the top and inner corner of the right foundation, and another height adjustment device 80 is located adjacent to the right foundation. The main cable 10 crosses the port access channel 1000 in the middle. The left end of the main cable 10 is operably connected to the horizontal traction winch 30 on the left after being changed in direction by the pulley assembly 81 of the height adjustment device 80 on the left and the shore-based guide wheel 40 on the left. The right end of the main cable 10 is operably connected to the horizontal traction winch 30 on the right after being changed in direction by the pulley assembly 81 of the height adjustment device 80 on the right and the shore-based guide wheel 40 on the right. One of the float devices 70 located at the left end remains in a constant position relative to the height adjustment device 80. For example, the float device 70 at the left end can be directly locked to the height adjustment device 80, or the float device 70 at the left end can be connected to the height adjustment device 80 via the flexible connecting rope 60, thereby keeping the position of the float device 70 at the left end relative to the height adjustment device 80 constant (it should be noted that, in this invention, the constant position of the float device 70 at the left end relative to the height adjustment device 80 means that the change between the two is very small and can be ignored). One of the float devices 70 located at the right end is fixedly connected to the main cable 10.

[0038] During the process of the horizontal traction winch 30 on the left taking in the cable and the horizontal traction winch 30 on the right releasing the cable, when one of the float devices 70 on the right moves to the position of the second float device 70 from the right to the left, it will pull the float device 70 to move synchronously to the left. In this way, all the float devices 70 can be pulled to the left. During this process, these float devices 70 pull the fiber optic defense net 20 to the left. When all the float devices 70 have moved to the position of the left base, for example, when all the float devices 70 have moved to the receiving slot of the left base, the fiber optic defense net 20 is completely retracted. As the horizontal traction winches 30 on the left and the horizontal traction winches 30 on the right release the cable, the middle of the main cable 10 sinks, opening the port access channel 10000 to allow ships to pass.

[0039] Correspondingly, during the process of the horizontal traction winch 30 on the right side retracting the cable and the horizontal traction winch 30 on the left side releasing the cable, when one of the float devices 70 on the right moves to the point where the flexible connecting rope 60 connecting the first float device 70 on the right and the second float device 70 from right to left is taut, it will pull the float device 70 to move synchronously to the right. In this way, all the float devices 70 can be pulled to the right. During this process, these float devices 70 pull the fiber optic defense network 20 to unfold to the right. When one of the float devices 70 on the right moves to the position adjacent to the height adjustment device 80 on the right, the fiber optic defense network 20 is fully unfolded. Based on the buoyancy provided by these float devices 70, the fiber optic defense network 20 is suspended in the port's access channel 1000 to prevent ships from passing. At this time, in the event of object or biological intrusion, the fiber optic defense network 20 can provide interception and early warning functions.

[0040] Understandably, the two height adjustment devices 80 determine the height of the main cable 10, the float devices 70, and the fiber optic defense network 20. Therefore, the port defense system can adjust the height of the main cable 10, the float devices 70, and the fiber optic defense network 20 through the two height adjustment devices 80.

[0041] In the port defense system of this utility model, since both the left and right bases are equipped with the environmental monitoring device 50, the environment of the port's access channel 1000 can be monitored. For example, the horizontal height change of the port's access channel 1000 can be monitored, or the wind force of the port's access channel 1000 can also be monitored. That is to say, the environmental monitoring device 50 can be an anemometer, a wave height meter, a camera, or a combination of anemometer, wave height meter, and camera. For example, in a specific example of this utility model, the left base is equipped with two wave height meters, two cameras, and two anemometers, and the right base is also equipped with two wave height meters, two cameras, and two anemometers. When the environmental monitoring device 50 is implemented as an anemometer, the wind speed of the port's access channel 1000 can be acquired. Based on the data provided by the anemometer, the port defense system can decide whether to retract the fiber optic defense network 20. For example, if the wind speed in the port's access channel 1000 is too high and lasts for too long, posing a risk of damage to the fiber optic defense network 20, the port defense system can retract the fiber optic defense network 20. When the environmental monitoring device 50 is implemented as a wave height meter, the water level in the port's access channel 1000 can be monitored. Based on the data provided by the wave height meter, the port defense system can control the state of the height adjustment device 80 to decide whether to adjust the height of the main cable 10, the buoy devices 70, and the fiber optic defense network 20. For example, when the wave height meter detects that the water level change in the port's access channel 1000 exceeds a warning value, the port defense system controls the height adjustment device 80 to adjust the height of the main cable 10, the buoy devices 70, and the fiber optic defense network 20. When the environmental monitoring device 50 is implemented as a camera, the environmental monitoring device 50 can collect water surface information to assist in the identification of water surface intrusion behavior and reduce the false alarm rate.

[0042] Continue to refer to the appendix Figure 1 The port defense system further includes at least one traffic light 90, which is disposed adjacent to the environmental monitoring device 50. For example, the traffic light 90 may be disposed on the right-side base, thus placing the traffic light 90 and the environmental monitoring device 50 on the right side adjacent to each other. The traffic light 90 may be a three-color traffic light, which provides an indication signal for passage or prohibition of passage through the port's access channel 1000. Optionally, in some embodiments of the port defense system of this utility model, the traffic light 90 may be disposed on both the left-side base and the right-side base.

[0043] Continue to refer to the appendix Figure 1The port defense system also includes a series of bottom-mounted counterweights 100, which are set at the bottom of the fiber optic defense network 20 to ensure that the fiber optic defense network 20 sinks to the seabed to achieve a sealed barrier.

[0044] Continue to refer to the appendix Figure 1 The port defense system further includes a control device 110, which includes a PLC controller. The two horizontal traction winches 30, the two environmental monitoring devices 50, the two height adjustment devices 80, and the traffic lights 90 are all connected to the control device 110. The control device 110 communicates with the two horizontal traction winches 30, the two environmental monitoring devices 50, the two height adjustment devices 80, and the traffic lights 90 to receive signals from the two horizontal traction winches 30, the two environmental monitoring devices 50, the two height adjustment devices 80, and the traffic lights 90, and to control the status of the two horizontal traction winches 30, at least one of the environmental monitoring devices 50, the two height adjustment devices 80, and the traffic lights 90.

[0045] Continue to refer to the appendix Figures 2 to 10D The height adjustment device 80 further includes a float assembly 82, a locking assembly 83, and a column 84.

[0046] Specifically, the locking assembly 83 includes a hydraulic mechanism 831 and two locking pins 832. The hydraulic mechanism 831 has a telescopic arm 8311 on each of its opposite sides. Each locking pin 832 has a driven end 8321 and a locking end 8322 on each side. The driven end 8321 of the locking pin 832 is drivably disposed on the telescopic arm 8311 of the hydraulic mechanism 831. When the telescopic arm 8311 of the hydraulic mechanism 831 extends or retracts, the telescopic arm 8311 of the hydraulic mechanism 831 drives the locking pins 832 to extend or retract synchronously.

[0047] The hydraulic mechanism 831 is mounted on top of the float assembly 82, and the pulley assembly 81 is mounted on top of the hydraulic mechanism 831. Thus, the pulley assembly 81, the locking assembly 83, and the float assembly 82 are integrated into a single unit. Specifically, the bottom of the float assembly 82 has at least one top stud 821, and the hydraulic mechanism 831 has at least one mechanism through hole 8313. Each top stud 821 of the float assembly 82 passes through each mechanism through hole 8313 of the hydraulic mechanism 831 and is then screwed with a nut to mount the hydraulic mechanism 831 to the top of the float assembly 82. Preferably, the pulley assembly 81 has a pulley seat through hole 811, and each of the top studs 821 of the float assembly 82 is screwed with a nut after passing through each of the mechanism through holes 8313 of the hydraulic mechanism 831 and each of the pulley seat through holes 811 of the pulley assembly 81 in sequence, so as to install the hydraulic mechanism 831 on the top of the float assembly 82 and to install the pulley assembly 81 on the hydraulic mechanism 831.

[0048] The column 84 has a columnar space 841, a side opening 842, and two rows of locking holes 843. Both the columnar space 841 and the side opening 842 extend along the height direction of the column 84, and the side opening 842 connects to the columnar space 841. The two rows of locking holes 843 are distributed at intervals along the height direction of the column 84 on opposite sides of the column 84, and each locking hole 843 connects to the columnar space 841. The float assembly 82 is buoyantly disposed within the columnar space 841 of the column 84; that is, the entire assembly consisting of the pulley assembly 81, the locking assembly 83, and the float assembly 82 can float vertically within the columnar space 841 of the column 84.

[0049] The locking pin 832 of the locking assembly 83 is configured to allow the locking end 8322 of the locking pin 832 to insert into and disengage from the locking hole 843 of the column 84. When the locking end 8322 of the locking pin 832 of the locking assembly 83 is inserted into the locking hole 843 of the column 84, even if the water level change in the port access channel 1000 exceeds the warning value, the whole consisting of the pulley assembly 81, the locking assembly 83, and the float assembly 82 will not float up and down within the column space 841 of the column 84. When the locking end 8322 of the locking post 832 of the locking assembly 83 disengages from the locking hole 843 of the column 84, based on the buoyancy provided by the float assembly 82, the whole consisting of the pulley assembly 81, the locking assembly 83 and the float assembly 82 can float up and down within the column space 841 of the column 84, so that the height of the fiber optic defense network 20 can be adaptively adjusted according to changes in the water surface.

[0050] The hydraulic mechanism 831 is controllably connected to the control device 110, which controls the extension and retraction of the telescopic arm 8311 of the hydraulic mechanism 831. When the control device 110 controls the telescopic arm 8311 of the hydraulic mechanism 831 to retract, the telescopic arm 8311 drives the locking pin 832 to retract, causing the locking end 8322 of the locking pin 832 to disengage from the locking hole 843 of the column 84. When the control device 110 controls the telescopic arm 8311 of the hydraulic mechanism 831 to extend, the telescopic arm 8311 pushes the locking pin 832 to extend, causing the locking end 8322 of the locking pin 832 to insert into the locking hole 843 of the column 84.

[0051] During the process of the telescopic arm 8311 of the hydraulic mechanism 831 pushing the locking pin 832 outward, in order to avoid the locking end 8322 of the locking pin 832 colliding with the column 84, in this specific example of the port defense system of this utility model, refer to the appendix. Figure 4 , Figures 9 to 10DThe locking assembly 83 includes two sensors 833. The sensors 833 are disposed at the locking end 8322 of the locking post 832 and connected to the control device 110. The control device 110 controls the operating state of the hydraulic mechanism 831 based on data fed back from the sensors 833. Specifically, when the data fed back from the sensors 833 indicates that the locking end 8322 of the locking post 832 corresponds horizontally to the locking hole 843 of the column 84, the control device 110 controls the telescopic arm 8311 of the hydraulic mechanism 831 to extend outward, thereby pushing the locking end 8322 of the locking post 832 to extend and insert into the locking hole 843 of the column 84. The sensors 833 may be distance sensors.

[0052] Continue to refer to the appendix Figure 4 To protect the sensor 833, when the control device 110 controls the telescopic arm 8311 of the hydraulic mechanism 831 to push the locking post 832 outward, the sensor 833 is prevented from being collided with. The locking post 832 has a receiving cavity 8324, an end detection port 8325, and a side wire hole 8326. The end detection port 8325 and the side wire hole 8326 are respectively connected to the receiving cavity 8324. The sensor 833 is received in the receiving cavity 8324 of the locking post 832, and the detection surface of the sensor 833 faces the end detection port 8325 of the locking post 832. The wire 8331 for connecting the sensor 833 extends from the receiving cavity 8324 to the outside through the side wire hole 8326 of the locking post 832. With the above structure, when the control device 110 controls the telescopic arm 8311 of the hydraulic mechanism 831 to push the locking post 832 outward, even if the locking end 8322 of the locking post 832 is not aligned with the locking hole 843 of the column 84, the sensor 833 will not be collided with the column 84, thereby improving the reliability of the port defense system.

[0053] Reference Attachment Figures 2 to 4 , Figures 9 to 10DThe locking assembly 83 includes two connecting mechanisms 834. The connecting mechanisms 834 are connected to the telescopic arm 8311 of the hydraulic mechanism 831. The driven end 8321 of the locking pin 832 is connected to the connecting mechanisms 834. The driving end 8321 of the locking pin 832 is positioned on the telescopic arm 8311 of the hydraulic mechanism 831 by the connecting mechanisms 834. Preferably, the connecting mechanism 834 is rotatably mounted on the telescopic arm 8311 of the hydraulic mechanism 831. In this way, after the locking end 8322 of the locking pin 832 is inserted into the locking hole 843 of the column 84, when the water level changes (rising or falling), and the locking end 8322 of the locking pin 832 is subjected to lateral force (lateral refers to the direction perpendicular to the extension direction of the locking pin 832), the connecting mechanism 834 can prevent the telescopic arm 8311 of the hydraulic mechanism 831 from being subjected to lateral force, thereby protecting the hydraulic mechanism 831.
