[0045] The preferred embodiments of the present application will be described in detail below with reference to the drawings, which form a part of this application. The drawings and the associated descriptions are provided to illustrate the preferred embodiments of the present application and to explain the principles of the present application, but not to limit the scope of the present application.

[0046] As shown in Figures 1-2 , the present application provides a floating bridge module dedicated transport propulsion device, comprising two oppositely arranged transport propulsion monomers 1 and a transport plate 2 located between the opposite sides of the two transport propulsion monomers 1. The transport propulsion monomer 1 comprises an outer shell 11, a propulsion structure 12, a lifting assembly 13 and a clamping assembly 15. The outer shell 11 is streamlined in shape to reduce resistance during water transport. The propulsion structure 12 is arranged through the outer shell 11 to generate forward power, mainly using water power. The lifting assembly 13 is installed on the outer shell 11, and the transport plate 2 is connected to the lifting end of the lifting assembly 13. The transport plate 2 is used to place the floating bridge module, and the lifting assembly 13 is used to lift and lower the transport plate 2. By lifting and lowering the transport plate 2, the floating bridge module on it can be lifted and lowered. When the transport plate 2 is raised to the top end and lowered to the bottom end, it forms a catamaran shape and a monomer shape with the transport propulsion monomer 1, respectively. The clamping assembly 15 is arranged on the outer shell 11 and used to clamp the floating bridge module in the catamaran shape.

[0047] It can be understood that the monomer shape is referred to Figure 14 , when installing and uninstalling the floating bridge, the monomer shape is adopted, and the transport plate 2 is lowered to the bottom end to form a U-shaped state with the two transport propulsion monomers 1. At this time, the upper surface of the transport plate 2 is not much different from the height of the installation or uninstallation ground, and the stability is good, so that the floating bridge can be installed quickly and stably; the catamaran shape is referred to Figure 15In the floating bridge transportation process, the double body form is adopted, the transportation plate 2 is lifted to the top end, and the inverted U-shaped state is formed with the two transportation propulsion units 1, the floating bridge is lifted from the water, and the advantages of the double body ship are used to reduce the resistance, improve the mobility, increase the wave resistance, and better adapt to the critical battlefield or disaster area. In addition, the position of the clamping assembly 15 corresponds to the position of the floating bridge in the double body form, and the floating bridge module is clamped and fixed in the double body form position.

[0048] In an embodiment, in order to fold and reduce the volume of the device, referring to Figure 3 、 Figure 4 、 Figure 6 and Figure 7 , the transportation plate 2 includes two single plate bodies 21 which are hingedly connected and rotatably folded. Specifically, the two single plate bodies 21 can be folded and attached. A hydraulic mechanism 23 is further provided between the single plate body 21 and the lifting end of the lifting assembly 13. The single plate body 21 is connected to the lifting end of the lifting assembly 13 through the hydraulic mechanism 23. The hydraulic mechanism 23 is used to control the folding of the single plate body 21 and the attachment of the two outer housings 11. Specifically, by extending and contracting the hydraulic mechanism 23, the single plate body 21 is driven to perform a folding movement, and the two outer housings 11 are linked to be attached. A plurality of support frames 1102 are provided between the outer housing 11 and the single plate body 21 for supporting the bottom of the single plate body 21. One end of the support frame 1102 is hingedly connected to the inner bottom wall of the accommodating groove 102, and the other end of the support frame 1102 is limitingly slidably connected to the guide sliding groove 2101 opened on the bottom of the single plate body 21. When the two single plate bodies 21 are unfolded, the single plate body 21 is supported and the stability of the entire structure is maintained.

[0049] The other end of the support frame 1102 is provided with a pulley 1103 on both sides, and a strip-shaped groove is provided on both sides of the guide sliding groove 2101. The strip-shaped groove is used for the pulley 1103 to slide therein, so that the end of the support frame 1102 is limitingly slid.

[0050] Specifically, in order to have the function of folding and turning over, the hydraulic mechanism 23 includes a hydraulic push rod 231 and a rotating sliding block 232. The two ends of the hydraulic push rod 231 are respectively slidably connected to the vertical sliding groove 1101 opened on the outer housing 11 and hingedly connected to the top of the rotating sliding block 232. The rotating sliding block 232 is adjusted by rotating through the extension and contraction of the hydraulic push rod 231. The two ends of the rotating sliding block 232 are respectively hingedly connected to the lifting end of the lifting assembly 13 and the single plate body 21 on the corresponding side. The single plate body 21 is driven to perform a folding and turning over movement by the rotation of the rotating sliding block 232.

[0051] It can be understood that the tail end of the hydraulic push rod 231 is in sliding connection with the vertical sliding groove 1101, and in lifting, it can slide along the groove body for limiting and guiding lifting, and the tail end of the hydraulic push rod 231 has a degree of freedom of rotation when the telescopic adjusting rotary slider 232 is adjusted; when unfolded from the folded state, the hydraulic push rod 231 is extended, pushing the rotary slider 232 to overturn downward, and under the rotating action of the single plate body 21, the linkage support frame 1102 also rotates, the two single plate bodies 21 are unfolded upward, and the two side support frames 1102 relatively rotate, so as to form Figure 4 a position form, and vice versa, when folded, the hydraulic push rod 231 is retracted, turning the rotary slider 232 upward to be vertical, and the two single plate bodies 21 and the support frame 1102 also move to be vertical, so as to achieve the folding effect.

[0052] Further, in order to completely close the outer shell body 11 when folding, the two outer shell bodies 11 on the transportation and propulsion monomer 1 can be spliced, and the splicing surface is recessed inward to accommodate the accommodation groove 102 for accommodating the single plate body 21. Specifically, after the outer shell body 11 is closed, the two single plate bodies 21 folded in half are accommodated inside, and when folded, the single plate body 21 is accommodated in the accommodation groove 102. Among them, the opposite sides of the two outer shell bodies 11 on the transportation and propulsion monomer 1 are the splicable planes 101.

[0053] It can be understood that the boat-shaped device unfolded state is converted into the "submarine"-shaped device folded state, wherein the unfolded state is shown in Figure 1 , and the folded state is shown in Figure 16 Not only can the transportation space be saved during transportation of the device, but also the device can have higher mobility and travel speed to reach the floating bridge installation site after being put into water, and can also hide by diving into water in emergency.

[0054] In an embodiment, in order to have both the stabilizing effect on the floating bridge and the attracting effect on the folded state, referring to Figure 5 , the clamping assembly 15 includes a magnetic panel 151 and a compression spring 152, the magnetic panel 151 is connected with the outer shell body 11 through a plurality of compression springs 152, the magnetic panel 151 is used for generating magnetic force attraction when powered on and breaking off magnetic force attraction when powered off, and in clamping the floating bridge module, the magnetic panel 151 is powered on and mutually attracted with the floating bridge module, so as to clamp the floating bridge module. The compression spring 152 functions to reset the magnetic panel 151 after the magnetic panel 151 is powered off.

[0055] It can be understood that when the two outer shell bodies 11 are spliced, the two magnetic panels 151 are also spliced, and at this time, the two magnetic panels 151 can be mutually attracted, so as to fix the two transportation and propulsion monomers 1 in the folded state.

[0056] It should be noted that the magnetic panel 151 is made of an alloy panel and an energized coil, and the energized coil is installed in the panel to generate a larger magnetic attraction force. The gap of the alloy panel is sealed by water-tight material to ensure that water does not affect the work of the energized coil.

[0057] In one embodiment, in order to make the transportation propulsion device have autonomous power, referring to Figure 11 , the propulsion structure 12 includes a water suction end 121, an impeller pump 122, and a vector variable direction nozzle 123. The two ends of the impeller pump 122 are connected with the water suction end 121 and the vector variable direction nozzle 123 respectively. The water suction end 121 is used for water suction, and the vector variable direction nozzle 123 is used for water injection, forming a propulsion structure that sucks water from one side and sprays from the other side.

[0058] Specifically, the water suction end 121 penetrates the outer shell 11 from one side and extends to the outside away from one end of the impeller pump 122, and the vector variable direction nozzle 123 penetrates the outer shell 11 from the other side and extends to the outside away from one end of the impeller pump 122. Water is sucked from the side and sprayed from the back, thereby generating forward power.

[0059] It can be understood that the impeller pump 122 adopts a shaftless motor to drive the blade to rotate, which reduces the propulsion energy consumption and can better cooperate with the full power strategy; the vector variable direction nozzle 123 realizes multi-directional propulsion by rotating longitudinally and transversely, improves the maneuverability of the device, and enables the device to make convenient turns without rudder, thereby improving the maneuverability of the device.

[0060] In one embodiment, in order to facilitate the installation of the floating bridge module during traction, referring to Figures 8-10 , the single plate body 21 is provided with a longitudinal sliding groove 35, and the single plate body 21 is provided with a roller structure 3. The roller structure 3 is arranged in the longitudinal sliding groove 35, and the roller structure 3 is used for sliding on the top of the transportation plate 2 during the installation of the floating bridge, thereby reducing the frictional resistance.

[0061] It can be understood that the longitudinal sliding groove 35 is provided with a plurality of water permeable holes for water permeation.

[0062] Specifically, the roller structure 3 includes a double pulley 31, a return spring 32, a sliding structure 33 and an electromagnetic elastic stopper 34. The double pulley 31 is arranged at the lifting end of the sliding structure 33 and mainly contacts with the floating bridge module to facilitate the sliding of the floating bridge module thereon. The sliding structure 33 and the electromagnetic elastic stopper 34 are arranged in the longitudinal sliding groove 35. The sliding structure 33 is used to move in the vertical direction. The double pulley 31 is popped out during installation to reduce the friction force, so as to facilitate the traction installation. The double pulley 31 is lowered during transportation to make the floating bridge module adhere to the upper surface of the transportation plate 2, thereby improving the stability. The electromagnetic elastic stopper 34 is used to limit the position of the sliding structure 33 when the double pulley 31 extends out of the longitudinal sliding groove 35. Specifically, the electromagnetic elastic stopper 34 is positioned when the double pulley 31 is lifted. The return spring 32 is connected to the bottom of the sliding structure 33 and is used to provide the power for lifting the double pulley 31 when the double pulley 31 extends out. Specifically, the return spring 32 is used to lift the sliding structure 33 and pop up the double pulley 31 when the double pulley 31 needs to be popped up.

[0063] In order to have a better stress structure, the sliding structure 33 includes two pairs of inclined support rods 331 and six rolling bearings 332. The longitudinal sliding groove 35 is provided with a cross groove body corresponding to the number of the roller structure 3. The cross groove body is composed of a horizontal sliding groove 301 and a vertical sliding groove 302 perpendicular to the horizontal sliding groove 301. One end of the two inclined support rods 331 of one pair of inclined support rods 331 is hinged through a shaft 333 penetrating the two inclined support rods 331. The other end of the two inclined support rods 331 is respectively connected with one rolling bearing 332. The rolling bearing 332 is in sliding connection with the horizontal sliding groove 301. When the two rolling bearings 332 are close to each other, the hinged end of the inclined support rod 331 is convex. Conversely, when the two rolling bearings 332 are away from each other, the hinged end of the inclined support rod 331 is lowered. The two ends of the shaft 333 are respectively connected with the double pulley 31 and one rolling bearing 332. When the shaft 333 is convex, the double pulley 31 is lifted. When the shaft 333 is lowered, the double pulley is lowered, thereby achieving the functions of lifting and lowering. The rolling bearing 332 is in sliding connection with the vertical sliding groove 302. The vertical sliding groove 302 limits the rolling bearing 332 to move up and down along the vertical sliding groove 302. The return spring 32 is connected to the bottom of the shaft 333. When the rolling bearing 332 at the far end of the inclined support rod 331 is not limited, the return spring 32 is popped up to lift the shaft 333. Then, the rolling bearing 332 at the far end of the inclined support rod 331 is limited by the electromagnetic elastic stopper 34, thereby supporting the shaft 333. Conversely, without the limitation of the electromagnetic elastic stopper 34, the double pulley 31 is directly pressed into the longitudinal sliding groove 35 when the floating bridge module is placed.

[0064] It can be understood that the single line movement characteristics of the rolling bearing 332 and the sliding groove regulate the up and down route of the double pulley 31, and the structural design of the double inclined support frame matches the movement of the double pulley 31 with the movement of the rolling bearing 332 and disperses the force borne by the double pulley 31, thereby reducing the stress borne by each part.

[0065] Further, in order to facilitate positioning when the double pulley 31 is lifted, the electromagnetic elastic stopper 34 includes an electromagnet 341, a connecting spring 342, and a blocking slider 343. The two ends of the connecting spring 342 are respectively connected with the electromagnet 341 and the blocking slider 343. The electromagnet 341 is installed in the horizontal sliding groove 301. By electrifying the electromagnet 341, the blocking slider 343 is attracted and withdrawn from the horizontal sliding groove 301, thereby releasing the limiting of the corresponding rolling bearing 332. Conversely, the electromagnet 341 is de-energized, loses the adsorption force on the blocking slider 343, and the connecting spring 342 provides elastic force to push the blocking slider 343 into the horizontal sliding groove 301, thereby limiting.

[0066] In an embodiment, in order to facilitate energy supply, referring to Figure 2 , the transportation propulsion unit 1 further includes an energy supply module 14. The energy supply module 14 is used to supply electric energy to the device. The energy supply module 14 is a plurality of battery packs arranged in the outer shell 11.

[0067] It can be understood that the battery pack adopts thin and high energy density blade batteries. A plurality of blade batteries are attached to the inner wall of the outer shell 11 through regular arrangement. Such a design can reduce the use of space while meeting the power supply requirement and can provide sufficient heat dissipation area for the batteries.

[0068] In an embodiment, in order to have stable lifting function, referring to Figures 12-13 , the lifting assembly 13 includes a protective shell 131, a motor gear set 132 built in the protective shell 131, a screw rod 133 connected to the rotating end of the gear set 132, and a lifting block 134 threadedly connected to the screw rod 133. The protective shell 131 is provided with a guide opening 1311 for the penetration of the lifting block 134 and limiting and guiding the lifting of the lifting block 134. Specifically, the motor gear set 132 is composed of a motor and two vertically distributed bevel gears. The motor drives the two bevel gears to rotate, thereby driving the screw rod 133 to rotate and driving the lifting block 134 to lift along the guide opening 1311. The lifting block 134 is the lifting end of the lifting assembly 13.
