[0020] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] In order to solve the technical problems that the laying process of floating bridges usually relies on manual operation or large-scale mechanical equipment, has a large self-weight, low transportation and deployment efficiency, and insufficient intelligence and automation, the present invention provides a rigid-flexible combined floating bridge system and a method for erecting the floating bridge system, which can realize the automatic placement and connection of connection units, and at the same time realize the rapid and efficient laying of the floating bridge, significantly improving the deployment efficiency of the floating bridge, reducing the labor cost, and meeting the emergency needs. It solves the problems of low transportation and deployment efficiency, and insufficient intelligence and automation existing in the laying process of existing floating bridges.

[0022] In a first aspect, please refer to Figures 1 to 3 , an embodiment of the present invention provides a rigid-flexible combined floating bridge system, including: a plurality of mobile hulls 1, a plurality of connection units 2, and a plurality of placement devices 3. The plurality of mobile hulls 1 are arranged at intervals in sequence, and a storage area is formed in each mobile hull 1; the plurality of connection units 2 are respectively arranged on the mobile hulls 1, and have a storage state and a laying state. When the connection unit 2 is in the storage state, the plurality of connection units 2 are stacked in the storage area, and when the connection unit 2 is in the laying state, the plurality of connection units 2 are connected in sequence and extend to connect two adjacent mobile hulls 1; the plurality of placement devices 3 are respectively connected to two adjacent mobile hulls 1, and are used to guide the plurality of connection units 2 to be sequentially placed from the storage state to the laying state.

[0023] In this solution, the mobile hull 1 is used as the carrier of the connection unit 2 and the placement device 3. The mobile hull 1 can move flexibly on the water surface, providing a stable platform for the laying of the floating bridge. The connection unit 2 adopts a modular design and can be freely combined according to needs. It has a storage state and a laying state. In the storage state, the connection units 2 are centrally stacked and stored in the storage area of the mobile hull 1, which can reduce the occupied space and is convenient for transportation and storage. The placement device 3 is responsible for automatically placing the connection unit 2 from the storage area of the mobile hull 1 to the laying state, and connecting the connection units 2 in sequence through the guiding part 32 to form a complete floating bridge structure. This enables the floating bridge system to realize the rapid and efficient laying of the floating bridge, improving the erection efficiency and intelligent level of the floating bridge.

[0024] It should be noted that, please refer to Figure 1 and Figure 2, in this embodiment, the mobile hull 1 is the foundation of the floating bridge system. Based on a small waterplane area trimaran, it is modified and designed with built-in rocket anchors for anchoring, and a gantry 11 is fixedly installed at the tail. On both sides of the bottom of the mobile hull 1, power pods 12, that is, pod thrusters, are equipped. Driven by an electric motor, they constitute the main power source of the mobile hull 1, featuring high efficiency, flexible space configuration, low noise, and low vibration. The number of connection units 2 carried on the mobile hull 1 can be adjusted according to the combat environment. Each unit hull can carry up to 26 connection units 2, enabling a laying length of 1 kilometer for every 4 units.

[0025] Among them, the working principle of the power pod 12 is that the electric motor inside drives the propeller to rotate, thereby generating thrust to achieve the propulsion and control of the mobile hull 1. When the electric motor starts, power is transmitted to the propeller through the transmission device, causing the propeller to rotate underwater. The rotation of the propeller pushes the surrounding water molecules backward, thereby generating forward thrust to push the mobile hull 1 forward. By changing the rotation speed and direction of the propeller, the speed adjustment and steering control of the mobile hull 1 can be achieved.

[0026] To facilitate the guidance and control of the position of the mobile hull 1, please refer to Figure 1 , further, adjacent front and rear ships are connected by a mooring connection device 13. The mooring connection device 13 mainly consists of a cable 131 and a winch, which plays a role in improving the navigation stability and assisting in the laying of the floating bridge. Specifically, one end of the cable 131 is connected to the tail mooring point of the front ship, the other end is connected to the head mooring point of the rear ship, and it is wound around the winch. By retracting and releasing the winch, the length of the cable 131 can be controlled. While bearing force, it connects and guides the ship, thereby controlling the movement direction of the entire connected fleet and improving the sea navigation stability. During the construction of the floating bridge, initially, the cables 131 between the ships are not tightened. Subsequently, the mobile hull 1 sails out in a predetermined order. After the floating bridge is constructed, the winch tightens the cable 131, causing the fleet to be arranged in a straight line, thereby enhancing the stability of the floating bridge.

[0027] The connection unit 2 is the foundation of the entire floating bridge system. In this embodiment, it consists of a flexible airbag part and a rigid support part. The flexible airbag part is made of high-strength and corrosion-resistant airbags, having good buoyancy and wave resistance, and being able to maintain the stability of the floating bridge under harsh sea conditions. The rigid support part is made of lightweight and high-strength metal or composite materials, used to provide the necessary rigidity and bearing capacity of the floating bridge to ensure the safe passage of personnel and vehicles. The combination of the flexible airbag part and the rigid support part not only ensures the buoyancy of the floating bridge but also provides sufficient bearing capacity, enabling the floating bridge system to adapt to various complex environmental conditions.

[0028] In one of the embodiments, please refer toFigure 1 , Figure 2 , Figure 4 and Figure 5 , the flexible airbag part is a double - layer floating airbag, namely the extended airbag 21 and the built - in airbag 22. The rigid support part includes the upper panel 23, the middle panel 24 and the bottom panel 25. The extended airbag 21 is arranged outside the built - in airbag 22, and both the extended airbag 21 and the built - in airbag 22 are arranged in two layers. The upper panel 23 is arranged at the top of the top - layer airbag, the middle panel 24 is arranged between the two layers of airbags, and the bottom panel 25 is arranged at the bottom of the bottom - layer airbag. The extended airbag 21 can be stored in the panel when folded and can extend to both sides when inflated. When the airbag as a whole provides buoyancy, the main function of the built - in part is to ensure the longitudinal stiffness of the entire connecting unit 2. The extended part mainly expands the width of the connecting unit 2, reduces the aspect ratio of the length and width of a single - unit bridge body, enhances the balance performance of the unit body and enhances the anti - overturning ability of the bridge section under eccentric load. A flexible anti - puncture cloth 26 is covered outside the extended airbag 21. On the one hand, it ensures the operation safety of the extended airbag 21 in the working state. On the other hand, driven by the contraction and winding of the motor, it cooperates with the air valve opened by the extended airbag 21 to extrude the gas filled in the extended airbag 21 to complete the recovery of the extended airbag 21. At the same time, the design of the double - layer floating airbag enables the inner - layer airbag to ensure the normal operation of the overall airbag when the outer layer is broken, further improving the reliability and safety of the connecting unit 2.

[0029] Please refer to Figures 6 to 8 , in order to realize the delivery of the connecting unit 2, in this embodiment, each of the delivery devices 3 includes: a mounting part 31, a guiding part 32 and a plurality of grasping parts 33. The mounting part 31 is connected to one of the mobile hulls 1; one end of the guiding part 32 is connected to the mounting part 31, and the other end is connected to another adjacent mobile hull 1 to form a guiding path connecting two adjacent mobile hulls 1. The grasping part 33 includes a plurality of grasping members 331. The grasping members 331 are movably arranged on the guiding path of the guiding part 32 for connecting the connecting unit 2, and the grasping members 331 can move along the guiding path to sequentially deliver the connecting unit 2 from the storage area to the laying state. During the delivery process, the delivery device 3 connects the connecting unit 2 through the grasping members 331 and moves along the guiding path formed by the guiding part 32, so that the connecting unit 2 changes from the storage state to the laying state and is sequentially connected to form a floating bridge. The guiding part 32 can ensure the accurate delivery of the connecting unit 2 along the preset path, reduce manual intervention, and reduce the operation difficulty and error rate.

[0030] Further, in some possible embodiments, the guiding portion 32 is arranged obliquely, and the height of the connection end of the guiding portion 32 to the mounting portion 31 is greater than that of the other end. A plurality of the grasping members 331 are slidably connected to the guiding portion 32 and can move downward along the guiding path under the action of gravity to place the connecting unit 2 from the storage state to the laying state, realizing the automatic placement and quick connection of the connecting unit 2. The oblique arrangement of the guiding portion 32 and the gravity action of the grasping members 331 enable the connecting unit 2 to be automatically placed after being connected by the grasping members 331, greatly improving the laying efficiency.

[0031] In some possible embodiments, the mounting portion 31 includes an angle compensation bracket 311 and an angle adjustment member 312. One end of the angle compensation bracket 311 is rotatably connected to the moving hull 1. The guiding portion 32 has a positioning section 3201 which is connected to the angle compensation bracket 311 and extends from one end of the angle compensation bracket 311 to the other end. The angle adjustment member 312 is mounted on the moving hull 1, and its driving end is connected to the angle compensation bracket 311 for driving the angle compensation bracket 311 to rotate relative to the moving hull 1 to adjust the inclination angle of the positioning section 3201, thereby adjusting the placement angle of the connecting unit 2. Specifically, when the connecting unit 2 is in the storage state, the angle adjustment member 312 can be used to drive the angle compensation bracket 311 to rotate to adjust the positioning section 3201 to be horizontal, facilitating the connection of the connecting unit 2 by the grasping members 331 on the positioning section 3201. After the connection of the connecting unit 2 is completed, the angle adjustment member 312 is used again to drive the angle compensation bracket 311 to rotate to adjust the positioning section 3201 to an inclined state, so that the grasping members 331 can automatically place the connecting unit 2 along the guiding path to the laying state. Such a design not only improves the automation degree of the floating bridge laying, but also enables the placement angle of the connecting unit 2 to be adjusted according to actual needs, enhancing the flexibility and adaptability of the floating bridge system.

[0032] Multiple connecting units 2 are respectively placed one by one through the connection of multiple grasping members 331. The connecting units 2 in the storage state are stacked. When the multiple grasping members 331 are placing, they can successively grasp the connecting units 2 from the top or side of the storage area. During the placement process of each grasping member 331, it can independently move along the guiding path of the guiding portion 32 to accurately place the connecting unit 2 at a predetermined position.

[0033] Further, in order to prevent the grasping member 331 from accidentally slipping, in some embodiments, the guiding portion 32 further has a winding section 3202 for accommodating a plurality of grasping members 331 for sequential use when the connecting unit 2 is placed. One end of the winding section 3202 is connected to the positioning section 3201, and the other end is disposed obliquely downward to form a winding path, and several connecting units 2 are connected to the winding path. When several connecting units 2 are in the storage state, several grasping members 331 are all connected to the winding section 3202 and arranged along the winding path to prevent the grasping members 331 from accidentally slipping. The mounting portion 31 further includes a positioning pusher 313 disposed on one side of the angle compensation bracket 311. The positioning pusher 313 is selectively connected to the grasping member 331 for pushing the grasping member 331 to move along the winding section 3202 to the positioning section 3201. During the placement process, the positioning pusher 313 sequentially pushes the grasping members 331 along the winding section 3202 to the positioning section 3201 according to a preset program or a manual instruction, so that the grasping members 331 can slide along the guiding path to place the connecting unit 2.

[0034] Please refer to Figure 6 , Figure 9 and Figure 10, the dispensing device 3 is also equipped with a position adjustment function, which can adjust the position of the gripper 331 according to the actual situation to ensure its accurate connection with the connection unit 2. In some embodiments, two sets of oppositely arranged gripping parts 33 are provided in each storage section, and each set of gripping parts 33 is correspondingly connected to a set of mounting parts 31 and a set of guiding parts 32. The two sets of mounting parts 31, the two sets of guiding parts 32 and the two sets of gripping parts 33 form a set of dispensing devices 3; the dispensing device 3 further includes an X-axis moving member 35 and a Y-axis moving member 36. The X-axis moving member 35 is respectively connected to the two mounting parts 31 and is used to drive the two mounting parts 31 to move relative to each other. The mounting parts 31 can drive the gripping parts 33 to move along the X-axis direction of the gantry 11 to drive the two grippers 331 to grip the connection unit 2. When laying the connection unit 2, the positions of the two gripping parts 33 can be adjusted according to the width of the connection unit 2 so as to fix both sides of the connection unit 2 by using the two grippers 331. The Y-axis moving member 36 is installed on the gantry 11 and is connected to the X-axis moving member 35 and is used to drive the X-axis moving member 35 to drive the two gripping parts 33 to move synchronously along the Y-axis direction of the gantry 11, and the moving direction of the Y-axis moving member 36 is consistent with the laying direction of the connection unit 2. When the connection unit 2 is stored, multiple stacked connection units 2 can be sequentially placed along the Y-axis direction of the gantry 11. The Y-axis moving member 36 can drive the X-axis moving member 35 and the gripping parts 33 to move along the Y-axis direction of the gantry 11, and can accurately control the position of the gripper 331, enabling the angle compensation plate 3111 to move freely on the X-axis and Y-axis so as to grip and fix the connection unit 2.

[0035] Preferably, in this embodiment, the angle compensation frame 311 includes an angle compensation plate 3111, a positioning wheel 3112 and a winding wheel 3113. The angle adjustment member 312 includes a secondary winch 3121 and an adjusting cable 3122. The guiding member includes a guiding cable 321 and a main winch 322. The placing device 3 further includes a telescopic pull rod 34. Specifically, the left end of the angle compensation plate 3111 is rotatably installed at the bottom end of the telescopic pull rod 34. The telescopic pull rod 34 is installed on the X-axis moving member 35, and the position height of the angle compensation plate 3111 can be controlled. The secondary winch 3121 is connected to the right end of the angle compensation plate 3111 through the adjusting cable 3122. Four positioning wheels 3112 are provided and installed on one side of the angle compensation plate 3111 in the horizontal direction. Two winding wheels 3113 are provided and arranged on one side of the angle compensation plate 3111 in the vertical direction. The left end of the guiding cable 321 is connected to the next moving hull 1. The main winch 322 is installed on the angle compensation plate 3111. The right end of the guiding cable 321 is wound around the positioning wheel 3112 and the winding wheel 3113 and then connected to the winding end of the main winch 322. The part of the guiding cable 321 corresponding to the positioning wheel 3112 constitutes a positioning section 3201, and the part between the main winch 322 and the winding wheel 3113 forms a winding section 3202. The main winch 322 is used to wind or release the guiding cable 321. Before the connection unit 2 is placed, a plurality of grasping members 331 are all slidably arranged on the winding section 3202 of the guiding rail. The positioning pusher 313, according to a preset program or a manual command, sequentially pushes the grasping members 331 to move along the winding section 3202 to the positioning section 3201. During the placing process, the secondary winch 3121 drives the angle compensation plate 3111 to rotate relative to the telescopic pull rod 34 through the adjusting cable 322, so as to adjust the inclination angle of the positioning section 3201, enabling the grasping members 331 to slide along the positioning section 3201 and the guiding path to place the connection unit 2 into a laid state.

[0036] Further, please refer to Figures 6 to 8 , in some embodiments, the positioning pusher 313 is a multi-functional robotic arm 3131. The multi-functional robotic arm 3131 has a driving claw that can clamp the grasping member 331. The angle compensation plate 3111 is provided with a long groove 3111a. The multi-functional robotic arm 3131 is installed in the long groove 3111a and can move along the length direction of the long groove 3111a. When it moves, it can move along the length direction of the guiding cable 321. Moreover, the driving claw of the multi-functional robotic arm 3131 can contract. This enables the multi-functional robotic arm 3131 to flexibly clamp the grasping member 331, drive the grasping member 331 to move along the winding section 3202 to the positioning section 3201, and adjust the position of the grasping member 331 when necessary. Among them, the movement and telescopic movement of the multi-functional robotic arm 3131 along the long groove 3111a are both realized by their respective independent driving devices, which belong to the prior art and will not be elaborated here.

[0037] Please refer to Figure 6 、 Figure 9 and Figure 10 Figure 10 In one embodiment, two sets of X-axis moving members 35 are arranged in the gantry 11 to respectively control the positions of two angle compensation plates 3111. The X-axis moving member 35 is a chain lock moving mechanism, which includes a main frame body 351, a sliding frame 352, a chain 353 and a driving motor 354 for driving the chain 353 to move. The main frame body 351 is arranged on the gantry 11 of the mobile hull 1, the sliding frame 352 is installed on the main frame body 351 and is slidably arranged along the length direction of the main frame body 351. A number of hanging points are arranged on the chain 353, and the two angle compensation plates 3111 are respectively hung on the two hanging points through the sliding frame 352. By driving the chain 353 to move through the driving motor 354, the relative positions of the two mounting parts 31 and the grasping part 33 can be flexibly adjusted to adapt to connection units 2 of different widths.

[0038] In one embodiment, the Y-axis moving member 36 includes a number of power wheels 361. The number of power wheels 361 are respectively installed on both sides of the gantry 11 and are arranged along the Y-axis direction of the gantry 11, and are arranged in the top chute of the gantry 11. The power wheels 361 are driven by a motor and can rotate synchronously to drive the X-axis moving member 35 and the grasping part 33 to move along the Y-axis direction of the gantry 11.

[0039] It should be noted that in this solution, the specific forms of components such as the angle adjustment member 312, the positioning push member 313, the guiding part 32, the X-axis moving member 35 and the Y-axis moving member 36 are not limited to this, and other components or structures that can achieve the same or similar functions can be used for replacement. For example, the angle adjustment member 312 can adopt a driving device such as a hydraulic cylinder or a pneumatic cylinder, and the rotation of the angle compensation plate 3111 can be realized by controlling its expansion and contraction. The positioning push member 313 can also adopt a linear driving device such as a cylinder or an electric push rod to push the grasping member 331 to move along the winding section 3202 to the positioning section 3201. The guiding part 32 can adopt a structure such as a rigid rod or a flexible rope, as long as it can meet the placement requirements of the connection unit 2. The X-axis moving member 35 and the Y-axis moving member 36 can also adopt other forms of moving mechanisms, such as a lead screw nut mechanism, a synchronous belt drive mechanism, etc., to realize the precise movement of the grasping part 33 in the X-axis and Y-axis directions.

[0040] Please refer to Figures 6 to 8, in some possible embodiments, the grasping part 33 includes a connector 332 and a screw. The connector 332 is sleeved on the guiding rail and can slide along the guiding path of the guiding rail. The screw is fixed on the connector 332 and can rotate on the connector 332. A thread groove matching the screw is provided on the side part of the panel of the connecting unit 2. The placing device 3 further includes a tightening structure 4. The tightening structure 4 is installed on the installation part 31, and its driving end corresponds to the guiding path for driving the screw to screw into the thread groove. When placing the connecting unit 2, the connector 332 first slides to a predetermined position of the connecting unit 2 through the multi-functional robotic arm 3131. Subsequently, the screw is screwed into the thread groove on the side of the connecting unit 2 under the action of the tightening structure 4, thereby firmly connecting the connecting unit 2 to the grasping part 331.

[0041] For the convenience of positioning and connection, further, a first position 3111b and a second position 3111c are formed on the side of the angle compensation plate 3111. The tightening structure 4 is provided on both the first position 3111b and the second position 3111c. After the angle compensation plate 3111 grasps the connecting unit 2, the connector 332 is sequentially pulled to the first position 3111b and the second position 3111c along the guiding cable 321 by the multi-functional robotic arm 3131 to align with the connection port of the connecting unit 2 and connect the connecting unit 2 and the cable.

[0042] It should be noted that the tightening structure 4 can adopt devices such as an electric wrench or a pneumatic wrench, and drive the screw to screw into the thread groove through its rotational power to achieve the quick connection between the connecting unit 2 and the grasping part 331. Of course, in other possible embodiments, the connector 332 can also connect the connecting unit 2 through other connection methods, such as snap connection, magnetic attraction connection, etc., as long as the placing requirements of the connecting unit 2 can be met.

[0043] Of course, in other possible embodiments, the placing device 3 can also adopt other forms as long as it can place the connecting units 2 between the two moving hulls 1 in sequence. For example, the placing device 3 adopts a screw drive structure, which includes a motor, a guide rod, and a screw connecting adjacent two moving hulls 1. The motor is connected to the screw and can drive the screw to rotate. The guide rod is arranged along the length direction of the screw and is parallel to the screw. The placing device 3 further includes a sliding seat, which is screwed on the screw and slides along the length direction of the guide rod. By driving the motor, the sliding seat can be driven to move along the length direction of the screw. When placing the connecting unit 2, the sliding seats of multiple connecting units 2 can be sequentially connected to the screw, and the motor is used to drive the sliding seat to move along the screw, thereby driving the connecting unit 2 to be placed along a predetermined path.

[0044] Please refer to Figure 2, in some possible embodiments, the rigid-flexible combined floating bridge system further includes a lifting structure 5, which is connected to the moving hull 1 and is used to drive the connection unit 2 to lift or lower relative to the moving hull 1, so as to send the stacked connection units 2 one by one to the grasping position of the grasping part 33.

[0045] Preferably, in this embodiment, the lifting structure 5 adopts a lifting elevator 51, which can lift the connection unit 2 in an orderly manner, so as to convey the connection unit 2 to the grasping part 33 in an orderly manner. The lifting elevator 51 includes an elevator car and a driving device. The elevator car is used to carry the connection unit 2, and the driving device is used to drive the elevator car to lift and lower. When the connection units 2 are stored, a plurality of connection units 2 are stacked in the elevator car. When it is necessary to put the connection unit 2, the driving device is started to drive the elevator car to rise, and the connection unit 2 at the top layer is sent to the grasping position of the grasping part 33. After the grasping part 33 connects and fixes the connection unit 2 through the connector 332 and the screw, the elevator car rises by the height of one connection unit 2 again, and the next connection unit 2 is sent to the grasping position.

[0046] Of course, in other possible embodiments, the lifting structure 5 can also adopt other forms, such as a hydraulic lifting platform, a screw lift, etc., as long as it can realize the lifting or lowering of the connection unit 2.

[0047] Please refer to Figure 7 and Figure 8 , in some possible embodiments, an inflation port communicating with the inside thereof is provided on one side of the airbag of the connection unit 2; correspondingly, an inflation structure 6 is provided on the angle compensation plate 3111, and the inflation structure 6 is installed on the delivery device 3 and is used to inflate the connection unit 2 through the inflation port when the delivery device 3 is connected to the connection unit 2. The inflation function is realized by an air pump 61, the main body of which is placed on the position compensation frame, the air pipe 62 is connected to the angle compensation plate 3111, and the inflation port of the connection unit 2 is connected to the inflation interface 63 of the angle compensation plate 3111 through the multi-functional robotic arm 3131 for inflation.

[0048] Please refer to Figure 3 and Figure 11, in order to achieve a quick and reliable connection between the mobile hull 1 and the shore, in this embodiment, a landing module 7 is also provided. On the basis of the transportation and launching device 3, to meet the requirements of beach landing, the landing module 7 is specially designed as a landing floating trestle. The landing floating trestle is composed of a landing airbag 71, a deck 72, and a rotating shaft 73. Multiple decks 72 are sequentially connected through the rotating shaft 73, and the landing airbag 71 is fixed at the bottom of the splint. When the ship approaches the shore, the airbag quickly inflates and unfolds, and the decks 72 unfold sequentially through the rotating shaft 73. These inflatable high-strength airbags ensure the stability of passage while being quickly laid, enabling personnel and armaments to pass through quickly, stably, and in a short time.

[0049] During the mission execution, the lead ship rushes towards the shore first and activates its rocket anchor for anchoring operations to ensure that the trapdoor at the stern can float on the water surface, while greatly enhancing the stability of the entire system. Immediately afterwards, the landing floating trestle will automatically pop out to provide a stable passage for the landing force. This design not only ensures the stability of the landing operation but also significantly improves the shore-attack ability of the landing gantry 11 trimaran, enabling it to complete the landing mission more effectively.

[0050] In addition, in order to further improve the stability and safety of the pontoon bridge system and meet the requirements of intelligent monitoring of the pontoon bridge, in this embodiment, an intelligent monitoring and guarantee system is also designed, which is used to achieve full protection during the laying of the pontoon bridge. This system consists of two major parts: a network security and signal guarantee system, and a pontoon bridge operation environment monitoring and anti-aircraft system for drones.

[0051] The network security and signal guarantee system is divided into a communication guarantee module and a network security module. The communication guarantee module and the network security module interact with each other in practical applications and are used to guarantee the network security and communication stability of the pontoon bridge during pontoon bridge operations.

[0052] The communication guarantee module can be further divided into two main modules: ship-shore communication and inter-ship communication. Ship-shore communication involves the transmission process of command data between the command center and the pontoon bridge ship group. Specifically, it can be divided into two parts: first, the data output of the command center, and second, the data transmission through relay nodes. One or more relay nodes may be set to ensure the continuity of communication. Inter-ship communication refers to the communication process between ships within the pontoon bridge ship group.

[0053] For the detailed data output process of the ship-shore communication module command center, please refer to Figure 12, the command center outputs data to the relay node or the floating bridge ship group. Among them, the intelligent selection of communication links is based on the real-time operation situation. According to the communication characteristics and communication quality detection results of different communication links, a suitable link is selected for data transmission. The communication links include super Wi-Fi communication, 4G / 5G network communication, VSAT satellite communication, and frequency-hopping shortwave communication. Under normal operating conditions, the priority of the ship-shore communication link is super Wi-Fi communication > 4G / 5G network communication > VSAT satellite communication > frequency-hopping shortwave communication. Frequency-hopping shortwave communication is only used for emergency communication after system network security problems occur. The communication quality detection system aims to monitor the communication quality of each link in real time, so that when the main link fails or the quality deteriorates, it can switch to the backup link to ensure the continuous and reliable data transmission. It detects the signal strength, signal-to-noise ratio, packet loss rate, and delay in real time for communication quality analysis.

[0054] The data transmission process of the relay node of the ship-shore communication module is shown in detail in Figure 13 , the data transmission of the relay node in the second part of ship-shore communication is not an essential process in the ship-shore communication process. Only when the distance between the command center and the floating bridge ship group is too far, there is signal occlusion, signal interference, or affected by the nearby network deployment, is it necessary to set up a relay node to transmit data. In this part, if the identity verification fails, it will enter the network security module.

[0055] Please refer to Figure 14 , which is the flowchart of the ship-to-ship communication module. Under normal operating conditions of ship-to-ship communication, the signals are stable and each ship is connected through MESH self-organizing network. Audio and video conferences and group commands can be carried out among the ships. Among them, the intelligent selection of communication link system and the communication quality detection system still play a role. In special cases, the ship group can intelligently select to communicate through ultra-shortwave communication. At the same time, collect various parameters of the ship group, such as airbag pressure, hull deflection, draft and load, and feedback the data to the command center.

[0056] Please refer to Figure 15 , which is the flowchart of the network security module. The network security module is used to ensure that the military communication can quickly give feedback and response when facing external attacks, and ensure the communication security and the smooth completion of combat tasks. It has the functions of identity verification, alarm, blocking, repeated monitoring, ensuring emergency communication, and troubleshooting and repairing problems, and monitors the network security of the floating bridge ship group in real time and comprehensively, and plays a role in each communication module.

[0057] Please refer to Figure 16, which is a flowchart of the monitoring of the pontoon bridge operation environment and the air defense system against drones. Drones are widely used in modern military warfare, and monitoring and attacking drones are crucial for ensuring the safety of pontoon bridges. This system combines an air defense radar with a wind speed and direction sensor to accurately monitor and predict the attack on drones. Specifically, in the initial monitoring stage, the wind speed and direction sensor measures the environmental wind speed and direction information, and the air defense radar scans and monitors the airspace where the pontoon bridge is erected. Subsequently, it enters the drone detection stage. It is judged whether the radar detects a drone. If "no", the process ends. If "yes", it enters the next step. The azimuth and speed of the drone are calculated through the radar, and it is judged whether the drone enters the effective strike range. If "no", it is recalculated. If "yes", an attack is carried out, and the strike result is evaluated in combination with the radar information feedback. Subsequently, it is judged whether the target is hit.

[0058] In the second aspect, the embodiment of the present invention provides a method for erecting a pontoon bridge system, which includes the rigid-flexible combined pontoon bridge system described in any one of the above embodiments. The erection method of this bridge system specifically includes three stages: ship group driving, separation and throwing, and collision connection. The steps are as follows: S1. Ship group driving: Multiple mobile hulls 1 are in a connected state and carry the connection unit 2 to sail to a predetermined position; S2. Separation and throwing: Adjust the speeds of each mobile hull 1 to achieve differential driving, and at the same time use the throwing device 3 to gradually throw the connection unit 2; S3. Collision connection: Adjust the inter-ship positions of each mobile hull 1 to squeeze the connection unit 2 thrown between two mobile hulls 1, so that the connection units 2 are collision-connected.

[0059] Specifically, please refer to Figure 17 , ship group driving refers to the process in which the pontoon bridge ship group sails to the target position in a connected state by the mooring connection device 13 and carries the connection unit 2. The separation and throwing stage is the process of adjusting the speeds of each ship and performing differential driving after the ship group drives, and throwing the connection unit 2 while advancing. It should be noted that in this stage, the distance traveled by the front ship in the same time will be about two lengths of the connection unit 2 more than that of the rear ship, that is, the relative distance between the front and rear ships increases in an arithmetic progression until all the connection units 2 to be thrown on the front ship are thrown, and at this time the relative distance between the front ship and the rear ship begins to remain unchanged, except for special sea conditions. In this stage, the landing module 7 also completes the shore landing. At this time, the mooring connection device 13 pays out the cable, the landing module 7 sails to the shore, and the landing floating trestle pops out. In the collision connection stage, after the landing module 7 completes the landing behavior, the ship group adjusts the inter-ship positions, squeezes the connection unit 2, and the connection units 2 are collision-connected. After completion, each trimaran lowers the rocket anchor, the barge is anchored, and the mooring connection device 13 connecting each ship is winched to adjust the pontoon bridge shape.

[0060] Please refer to Figure 18, the engineering process of the delivery device 3 can be divided into four stages: adjusting the position of the angle compensation frame 311, lifting the elevator 51 upward, the angle compensation plate 3111 acting on the connection unit 2 (connecting the steel cable to inflate and expand to adjust the angle), and the connection unit 2 sliding down. When the angle compensation frame 311 adjusts the position, the position compensation slide rail works. According to the position of the connection unit 2 on the lifting elevator 51, the angle compensation plate 3111 moves on the x and y axes to align with the connection unit 2. During the stage of lifting the elevator 51, it is the stage where the telescopic rod of the angle compensation plate 3111 cooperates with the lifting elevator 51. The position where the angle compensation plate 3111 contacts the connection unit 2 is preset, and the two move towards this position simultaneously, so that the angle compensation plate 3111 contacts the connection unit 2. Note that in this stage, the main function of the movement of the telescopic rod is to finely adjust the contact position between the connection unit 2 and the angle compensation plate 3111, and the main movement process is completed by the lifting elevator 51. The action of the angle compensation plate 3111 refers to the process in which after the angle compensation plate 3111 contacts the connection unit 2, under the action of the angle compensation plate 3111, the assembly connector 332 connects the connection unit 2 and the steel cable, the connection unit 2 inflates and expands, adjusts the angle, and quickly slides down.

[0061] The present invention combines the flexibility of the mobile hull 1 and the modular design of the connection unit 2 by setting a plurality of mobile hulls 1, a plurality of connection units 2, and a plurality of delivery devices 3. The mobile hull 1 carries the connection unit 2, and the delivery device 3 automatically and orderly delivers the connection unit 2 from the storage state to the laying state, realizing the automatic delivery and connection of the connection unit 2, and at the same time realizing the rapid and efficient laying of the floating bridge, significantly improving the deployment efficiency of the floating bridge, reducing the labor cost, and meeting the emergency needs. It solves the problems of low transportation and deployment efficiency, and insufficient intelligence and automation in the existing floating bridge laying process.

[0062] In addition, by adopting the combination method of multiple mobile hulls 1 and connection units 2, the system can flexibly set the unit laying length, greatly improving the degree of freedom of assembly. At the same time, through the innovative rigid-flexible combination and lightweight design, it ensures that while maintaining the overall stability of the system, it can also effectively absorb and disperse the impact of external loads such as waves and water flows on the floating bridge structure. It realizes the efficient, stable and flexible application of the floating bridge, providing a reliable water passage solution for the military, rescue and engineering fields.
