Description

Technical Field

[0001] This invention belongs to the field of barrier net technology, specifically relating to a barrier net for intercepting ships. Background Technology

[0002] Barrier nets are devices commonly used in ports, waterways, and other areas to intercept and delay the navigation of target vessels. Traditional barrier nets are mostly deployed in a fixed manner or simply thrown, which makes it difficult to maintain an ideal vertical interception posture in water flow, resulting in poor interception effect and low deployment efficiency. They also have problems such as insufficient deployment flexibility, difficulty in quickly connecting to adjust the interception length, and insufficient adaptability in multi-tasking scenarios. Therefore, we propose a barrier net for intercepting vessels. Summary of the Invention

[0003] In order to overcome the above-mentioned technical problems, the purpose of this invention is to provide a barrier net for intercepting ships, so as to solve the problems mentioned in the background art. Traditional barrier nets mostly adopt fixed deployment or simple throwing methods, which make it difficult to maintain an ideal vertical interception posture in water flow, resulting in poor interception effect and low deployment efficiency. At the same time, they also have problems such as insufficient deployment flexibility, difficulty in quick connection to adjust the interception length, and insufficient adaptability in multi-task scenarios.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a barrier net for intercepting ships, comprising a first barrier rope and a second barrier rope, wherein multiple sets of connecting ropes are fixedly connected between the first barrier rope and the second barrier rope, a counterweight is fixedly connected to the bottom surface of the first connecting rope, multiple sets of floats are provided on the surface of the first barrier rope, a connecting structure is provided on the left side of the first barrier rope, the connecting structure includes two sets of fixing blocks, a connecting rope is fixedly connected between the two sets of fixing blocks, a magnet is fixedly connected to one side of the fixing block, a hand-tightening knob is rotatably connected inside the fixing block, a connecting structure is provided on the right side of the first barrier rope, the connecting structure includes two sets of fixing blocks, a connecting rope is fixedly connected between the two sets of fixing blocks, a magnet is fixedly connected to one side of the fixing block, a hand-tightening knob is rotatably connected inside the fixing block, a rotating plate is rotatably connected to the surface of the hand-tightening knob, and a groove is formed on the surface of the rotating plate.

[0005] Preferably, both the first and second barrier ropes are made of composite materials, and two sets of floats are symmetrically arranged at the top of each first barrier rope, with the floats fixedly connected to the surface of the first barrier rope.

[0006] Preferably, multiple sets of connecting ropes are equidistantly arranged between the first and second blocking ropes, two sets of counterweights are symmetrically arranged on the surface of the first connecting rope, and multiple sets of floats are symmetrically arranged on both sides of the top of the first blocking rope and the first connecting rope.

[0007] Preferably, the first connecting rope, the second connecting rope, and the third connecting rope are provided with steel wires inside.

[0008] Preferably, both the first and second hand-tightening knobs are provided with threads on their surfaces, the length of which is half the length of the first and second hand-tightening knobs. The rotating plate is provided with a circular groove on its surface, and the rotating plate is rotatably connected to the surface of the second hand-tightening knob through the circular groove.

[0009] Preferably, the slide groove is disposed on the surface of the rotating plate away from the circular groove, the cross-sectional width of the slide groove is greater than the width of the hand-tightening knob, and the rotating plate is slidably connected to the outside of the hand-tightening knob through the slide groove.

[0010] Preferably, the first magnet and the second magnet cooperate with each other.

[0011] Compared with the prior art, the beneficial effects of the present invention are: 1. This type of intercepting net for vessels is equipped with connecting ropes, counterweights, and floats. By symmetrically fixing multiple sets of floats to the upper edge of the first intercepting rope and symmetrically fixing multiple sets of counterweights to the bottom of the lower edge of the first connecting rope, after the net is placed in the water, the uniform buoyancy provided by the floats and the uniform sinking force provided by the counterweights counteract each other, allowing the entire net to autonomously adjust and stably maintain a state in which all connecting ropes, including connecting ropes one, two, and three, are nearly perpendicular to the water surface. This increases the contact area and the possibility of entanglement with the propellers of target vessels approaching laterally. Compared with traditional intercepting nets that may tilt or float unsteadily, this invention significantly improves the reliability and effectiveness of interception. At the same time, the way the floats and counterweights are fixed is firm, ensuring reliability for long-term use in dynamic water environments.

[0012] 2. This type of ship-intercepting barrier net features two connecting structures: Connecting Structure 1 and Connecting Structure 2. The cooperation of Connecting Structure 1 and Connecting Structure 2 enables rapid splicing between two sections of the barrier net. Through the strong attraction of Magnet 1 and Magnet 2, operators can easily guide the joint ends of the two net sections to the accurate position and achieve initial adhesion, eliminating the tedious manual alignment steps. This is particularly suitable for operation on swaying ship decks or at night, and other adverse conditions. After initial adhesion, the rotating plate of this net section is rotated, causing its groove to engage with the screw of the hand-tightening knob 1 of the net section to be connected. Then, they are connected separately... Tighten both hand-tightening knobs one and two. During the tightening process, hand-tightening knob two pushes the rotating plate, causing the inner wall of the slide groove to press tightly against the side of the screw of hand-tightening knob one. At the same time, tightening hand-tightening knob one also strengthens its fixation within its own fixing block one, thus forming a solid rigid connection point between the two sections of the net. This magnetic-assisted positioning combined with mechanical screw locking method is not only fast and easy to operate, but also has high connection strength. It can effectively transmit the tensile force generated during interception, realizing flexible and rapid expansion of the length of the barrier net, improving deployment efficiency and tactical adaptability.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1-5 One embodiment provided by the present invention: A ship-intercepting barrier net includes a first barrier rope 1 and a second barrier rope 2. Multiple sets of connecting ropes 3 are fixedly connected between the first barrier rope 1 and the second barrier rope 2. A counterweight 4 is fixedly connected to the bottom surface of each connecting rope 3. Multiple sets of floats 5 are provided on the surface of the first barrier rope 1. A connecting structure 6 is provided on the left side of the first barrier rope 1. The connecting structure 6 includes two sets of fixing blocks 61, with a second connecting rope 62 fixedly connected between the two sets of fixing blocks 61. A magnet 63 is fixedly connected to one side of each fixing block 61. A hand-tightening knob 64 is rotatably connected inside each fixing block 61. A connecting structure 7 is provided on the right side of the first barrier rope 1. The connecting structure 7 includes two sets of fixing blocks 71, with a third connecting rope 72 fixedly connected between the two sets of fixing blocks 71. A magnet 73 is fixedly connected to one side of the fixing block 71. A hand-tightening knob 74 is rotatably connected inside the fixing block 71. A rotating plate 75 is rotatably connected to the surface of the hand-tightening knob 74. A groove 76 is provided on the surface of the rotating plate 75. A connecting rope 3, a counterweight 4, and floats 5 are installed. By symmetrically fixing multiple sets of floats 5 to the upper edge of the blocking rope 1, and symmetrically fixing multiple sets of counterweights 4 to the bottom of the lower edge of the connecting rope 3, after the net is placed in the water, the uniform upward buoyancy provided by the floats 5 and the uniform downward buoyancy provided by the counterweights 4 counteract each other, allowing the entire net to adjust itself and maintain a stable state in which all the connecting ropes, including connecting rope 3, connecting rope 2 62, and connecting rope 3 72, are nearly perpendicular to the water surface, increasing the... Compared to traditional barrier nets that may tilt or float, this invention significantly improves the reliability and effectiveness of interception by reducing the contact area and entanglement possibility with the propellers of horizontally approaching target vessels. Simultaneously, the secure fixing method of the float 5 and the counterweight 4 ensures long-term reliability in dynamic water environments. Connecting structure 6 and connecting structure 7 are provided; their cooperation enables rapid splicing between two sections of the barrier net. Through the strong attraction of magnets 63 and 73, operators can easily guide the joint ends of the two net sections to the accurate position and achieve initial adhesion, eliminating tedious manual alignment steps. This is particularly suitable for operation in harsh conditions such as swaying vessel decks or at night. Then, rotate the rotating plate 75 of this net segment so that its slide groove 76 engages with the screw of the hand-tightening knob 64 of the net segment to be connected. Then, tighten the hand-tightening knob 64 and the hand-tightening knob 74 respectively. During the tightening process, the hand-tightening knob 74 pushes the rotating plate 75 so that the inner wall of the slide groove 76 is tightly pressed against the side of the screw of the hand-tightening knob 64. At the same time, the tightening of the hand-tightening knob 64 also strengthens its fixation within its own fixing block 61, thus forming a solid rigid connection point between the two net segments. This magnetic suction-assisted positioning and mechanical screw locking method is not only fast and easy to operate, but also has high connection strength. It can effectively transmit the tensile force generated during interception, realize the flexible and rapid expansion of the length of the barrier net, and improve deployment efficiency and tactical adaptability.

[0017] Furthermore, both barrier rope 1 and barrier rope 2 are made of composite materials, possessing excellent tensile strength and environmental resistance, ensuring the net can work effectively for a long time in harsh marine environments. Each set of connecting ropes 3 has two sets of floats 5 symmetrically arranged at the top. The floats 5 are fixedly connected to the surface of barrier rope 1, providing not only backup buoyancy and enhancing reliability, but more importantly, by applying force symmetrically from both sides, helping to maintain the flatness of the net surface at the connection point and preventing local overturning or twisting. The connection between the floats 5 and barrier rope 1 adopts a high-strength, water-resistant fixing process, such as locking with metal clamps with internal anti-slip teeth, or using high-polymer materials for direct injection molding to form an irreversible and firm bond, ensuring that the floats 5 will not accidentally detach.

[0018] Furthermore, multiple sets of connecting ropes 3 are equidistantly arranged between barrier ropes 1 and 2. The grid structure facilitates smooth water flow, reduces water resistance, and prevents large deformation of the net due to uneven stress. It also more effectively covers and wraps around the propeller. Two sets of counterweights 4 are symmetrically arranged on the surface of the connecting ropes 3 to ensure that the torque generated by the floats 5 above is basically balanced, so that a single connecting rope 3 can remain vertical in the water. The vertical state of all connecting ropes 3 combined ensures that the entire net is perpendicular to the water surface. Multiple sets of floats 5 are symmetrically arranged on both sides of the top of the barrier ropes 1 and connecting ropes 3. Through this distributed layout, buoyancy is evenly applied to the upper edge of the net. It works in conjunction with the gravity of the distributed counterweights 4 to form a dynamic and stable attitude control system. Even under water impact or local stress, the net can quickly restore its vertical attitude through self-adjustment and maintain the best interception effect. The counterweights 4 include, but are not limited to, lead sinkers.

[0019] Furthermore, connecting rope 3, connecting rope 62, and connecting rope 72 are internally equipped with steel wires. This allows the ropes to retain the softness, easy winding (facilitating propeller winding), and corrosion resistance of the fiber material, while the inner steel wires greatly enhance the overall tensile strength, cut resistance, and dimensional stability (low elongation). When subjected to enormous tensile force, the inner steel wires bear the main load first, effectively preventing the net from being pulled apart or excessively elongated, which could lead to mesh deformation and interception failure. This improves the reliability and durability of the barrier net under extreme conditions.

[0020] Furthermore, both the first and second hand-tightening knobs 64 and 74 are threaded, with the thread length being half the length of each knob. This sufficient thread length ensures the strength and self-locking of the connection. The smooth section of the screw without threads allows the sliding groove 76 of the rotating plate 75 to smoothly fit into the initial alignment, avoiding thread interference. The rotating plate 75 has a circular groove 1 on its surface, which is rotatably connected to the surface of the second hand-tightening knob 74. This allows the rotating plate 75 to rotate freely during docking operations, enabling the sliding groove 76 to easily align with and fit into the other segment of the hand-tightening knob 64, making the operation flexible and convenient.

[0021] Furthermore, the slide groove 76 is located on the surface of the rotating plate 75 away from the circular groove. The cross-sectional width of the slide groove 76 is greater than the width of the hand-tightening knob 64. The rotating plate 75 is slidably connected to the outside of the hand-tightening knob 64 through the slide groove 76. During the connection operation, after the magnet is initially positioned by adsorption, the rotating plate 75 is rotated so that the opening of the slide groove 76 is aligned and fitted into the screw of the hand-tightening knob 64 extending from the adjacent mesh segment. At this time, the inner wall of the slide groove 76 and the outer wall of the screw of the hand-tightening knob 64 form contact. This sliding fitting process completes the initial mechanical coupling and alignment of the connection mechanism between the two mesh segments, laying the foundation for the final locking in the next step.

[0022] Furthermore, magnet 63 and magnet 73 work together to generate sufficient adsorption force, enabling the two sets of connecting structures to quickly pre-position and remain in close contact during the initial docking stage. This facilitates subsequent mechanical locking. When connecting two sections of the barrier net, the operator only needs to bring the end of the net section with connecting structure 7 roughly towards the end of the other net section with connecting structure 6. Under the action of the magnetic force, magnet 73 will automatically find and adhere to magnet 63, thereby quickly pulling the end faces of the two connecting structures together and aligning them. This process requires almost no manual precision alignment, greatly simplifying the operation. This advantage is particularly evident in scenarios with insufficient light, turbulent water surfaces, or when gloves are required. Magnetic adsorption achieves initial fixation, allowing subsequent mechanical locking operations to be performed in a relatively stable state.

[0023] Working principle: In actual use, coast guard vessels typically launch single or multiple connected sections of the barrier net rapidly into the target waters using a specialized launching device. After the net enters the water, multiple sets of buoys 5 symmetrically arranged on the barrier rope 1 generate upward buoyancy, causing the barrier rope 1 to float near the water surface. Meanwhile, the counterweights 4 symmetrically arranged at the bottom of each connecting rope 3 generate downward gravity, pulling the barrier rope 2 downwards towards the bottom. Under the combined action of these two opposing and evenly distributed forces, the entire net rapidly unfolds and self-adjusts, making all longitudinal connecting ropes 1 3, 2 6 2, and 3 7 2 approximately vertical. The net, positioned on the water's surface, forms a large-area vertical flexible barrier underwater. When a target vessel attempts to cross this area, its propeller easily cuts into and gets caught in this vertical net. The net's flexibility allows it to effectively entangle the propeller blades, and the immense resistance causes the propeller to quickly lose propulsion efficiency, or even cause the engine to overload and shut down, thus effectively intercepting and hindering the target vessel. When the interception area is wide and the length of a single section of the barrier net is insufficient, the quick connection function of this invention can be used for expansion. The connection process is efficient and reliable: First, connect the connecting structure 7 on the right side of one section of the barrier net to the left side of another section of the barrier net. When the connecting structures 6 and 73 are brought close together, they will automatically attract and align under the strong magnetic attraction of magnets 73 and 63, completing the initial positioning and fixing. Then, the operator uses their hand (or a simple tool) to loosen the hand-tight knob 74 of the current mesh segment (with connecting structure 7) and the hand-tight knob 64 of the mesh segment to be connected (with connecting structure 6), causing the screws to slightly retract, providing space for the rotation and sliding of the rotating plate 75. Next, the rotating plate 75 on the connecting structure 7 is rotated, causing the groove 76 on its surface to rotate until it aligns with and fits the screw of the hand-tight knob 64 of the mesh segment to be connected. Finally, the screws are respectively... Tighten both the first hand-tightening knob 64 and the second hand-tightening knob 74. When the second hand-tightening knob 74 is tightened, its forward movement pushes the rotating plate 75, causing the side wall of the slide groove 76 to press tightly against the side of the screw of the first hand-tightening knob 64. At the same time, tightening the first hand-tightening knob 64 also makes its screw more firmly fixed in its own fixing block 61. Through the process of magnetic initial positioning, slide groove 76 engagement, and spiral pressing, the ends of the two sections of the barrier net are firmly mechanically locked together. The connection strength is sufficient to withstand the huge tensile force generated during the interception operation. Repeating this process, multiple sections of the barrier net can be quickly connected to the required length, greatly improving the flexibility of deployment and the efficiency of operation.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
