[0002] Floating bridges can be used for pedestrians, roads, and railways. Their structure is not complicated and they are easy to erect and dismantle, but the maintenance cost is high. They can be used for emergency rescue or as temporary transportation facilities in normal times. In order to increase their maneuverability, they are often made of light metal and self-propelled.

[0003] In the prior art, there is a telescopic floating bridge disclosed in Chinese patent number CN104005330B. The bridge comprises a support frame and a bridge deck. The support frame comprises two rows of side frames, each of which is connected to a telescopic drive device for the side frames. The two side frames are connected as a whole by a transverse rod. Each row of side frames is a linkage telescopic structure formed by a plurality of hinged X-shaped components hinged in sequence. Each component is connected to a foldable connecting rod. The bridge deck is hinged on the transverse rod. The bridge deck is hinged at the head and tail to form an integral whole. The support frame is a telescopic structure that can be unfolded when in use and retracted when not in use, making it convenient to transport. The support frame can be telescopic, so it does not need to be erected on site. It can be erected at ordinary times and directly transported to the site for unfolding and use.

The water body 28 pulls the first slide bar 27 and pulls the airbag 23, so that negative pressure is generated inside the airbag 23. At this time, outside air enters through the air inlet 67.

The inner surface of the sealing door 60 is fixedly connected to a second tension spring 62, and one end of the second tension spring 62 is fixedly connected to a pull rod 61. Both ends of the pull rod 61 are fixedly connected to the inner wall of the gas distribution pipe 20. The gas enters the drying component 21 above through the gas distribution pipe 20, and then the gas pushes open the sealing door 60 and blows out the gas to dry the drainage groove 31 inside the bridge body 1.

[0036] Example 2: Please refer to Figure 5 - Figure 9 The present invention provides a technical solution: on the basis of embodiment 1, air outlets 68 are provided at both ends of the air distribution pipe 20, and a sealing ring 66 is fixedly connected to the inner wall of the air distribution pipe 20, and a second sliding rod 64 is slidably connected to the inner surface of the sealing ring 66, and the top of the second sliding rod 64 is fixedly connected to a second spring 65, and the bottom end of the second spring 65 is fixedly connected to the upper surface of the sealing ring 66, and the lower surface of the second sliding rod 64 is fixedly connected to a sealing plate 63, and an air inlet 67 is provided on the inner surface of the air distribution pipe 20. The above functions solve the problem that the surface of the bridge body 1 cannot dry quickly after rain in traditional equipment, affecting the driving safety of vehicles on the bridge deck, and cannot generate electricity through buoyancy to produce clean energy.

[0037] The guardrail device 2 includes a pull rope 40, both ends of which are fixedly connected to the outer surface of the hatch 11, the outer surface of the pull rope 40 is slidably connected to a railing 41, the outer surface of the railing 41 is fixedly connected to the outer surface of the bridge body 1, the outer surface of the railing 41 is fixedly connected to a rotating rod 43, the outer surface of the rotating rod 43 is fixedly connected to a pull rod 42, the outer surface of the rotating rod 43 is fixedly connected to a rope hook 44, the outer surface of the rope hook 44 is in contact with the outer surface of the pull rope 40. The above functions solve the problem that when traditional equipment encounters people in need of rescue, a third party cannot easily and quickly pull the pull rope 40 to pop out the lifebuoy 52.

[0038] The cleaning device 3 includes a screw rod 30, the outer surface of which is threadedly connected to an inner screw block 33, the outer surface of the inner screw block 33 is slidably connected to the outer surface of the bridge body 1, a plurality of drainage grooves 31 are provided inside the bridge body 1, and a cleaning component 32 is provided inside the bridge body 1. The motor fixedly connected to one end of the screw rod 30 is started, and the rotation of the motor drives the screw rod 30 to rotate, and the screw rod 30 drives the inner screw block 33.

[0039] The cleaning assembly 32 includes a shaft 34, the outer surface of which is rotatably connected to a plurality of plow-shaped scrapers 35, the outer surface of which is slidably connected to the inner surface of the bridge body 1, and the outer surface of the shaft 34 is slidably connected to the inner surface of the bridge body 1. The above functions solve the problem that traditional equipment cannot clean the dirt inside the drainage trough 31.

[0040] The outer surfaces of both ends of the shaft 34 are fixedly connected to the outer surface of the inner screw block 33. The screw rod 30 drives the inner screw block 33, and the inner screw block 33 drives the shaft 34 to move toward the two ends of the bridge body 1. The shaft 34 drives the plow-shaped scraper 35, and the plow-shaped scraper 35 slides inside the drainage groove 35 to discharge the internal dirt.

[0041] Working principle:

[0042] During use, when the car travels to the upper surface of a single bridge body 1, the gravity of the car causes the bridge body 1 to sink as a whole. At this time, the water body 28 drives the first slide bar 27 to float upward under the action of water resistance. The first slide bar 27 first causes the generator coil 26 to slide upward inside the magnetic shell 25 to cut the magnetic flux lines, and charge the battery inside the battery shell 12. Later, in the process of floating up, the first slide bar 27 pushes the airbag 23, and then the airbag 23 compresses the air inside and enters the four air distribution pipes 20, and the first spring 24 is compressed to prepare for the subsequent reset of the airbag 23. The gas enters the drying component 21 above through the air distribution pipe 20, and then the gas pushes open the sealing door 60, blows out the gas, and is used to dry the drainage groove 31 inside the bridge body 1, and the second tension spring 62 pulls the sealing door 60 by elastic potential energy after the gas is discharged, sealing the air outlet 68 when the car passes through the single bridge body 1;

[0043] When the bridge body 1 floats up, the resistance of the water body 28 in the water and the buoyancy of the bridge body 1 floating up cooperate with each other, and the water body 28 pulls the first slide bar 27 and the airbag 23, so that negative pressure is generated inside the airbag 23. At this time, the outside air enters through the air inlet 67, pushes open the sealing plate 63, and the gas flows into the airbag 23. In the process of pushing open the sealing plate 63, the sealing plate 63 pulls the second slide bar 64 downward. At this time, the second slide bar 64 deforms the second spring 65 to prepare for the subsequent reset of the sealing plate 63. The above functions solve the problem that the surface of the bridge body 1 may not dry quickly after rain in traditional equipment, affecting the driving safety of vehicles on the bridge deck, and it is impossible to generate electricity through buoyancy to produce clean energy.

[0044] During use, when the car is driving, it may lose control. When the vehicle hits one side of the bridge body 1 and falls into the water, the vehicle pulls the railing 41 and the pull rope 40 inside the railing 41. The pull rope 40 slides inside the railing 41 to pull the hatch 11 at the hit end, and the hatch 11 rotates upward to open. At the same time, when the hatch 11 rotates, the first tension spring 51 connected to the inside of the hatch 11 is pulled, and the first tension spring 51 pulls the push plate 53 to move toward the hatch 11. Then the push plate 53 will push the lifebuoy 52 out of the inside of the bridge body 1 and float on the water. The above functions solve the problem that traditional equipment cannot eject the lifebuoy 52 for the people in the car to ensure the safety of others' lives when the vehicle accidentally falls into the water.

[0045] During use, when someone falls into the water and needs to be rescued during driving, the lever 42 can be manually rotated upwards, and the lever 42 rotates inside the rotating rod 43, and drives the rope hook 44 to rotate and move downward. At the same time, the rope hook 44 will drive the pull rope 40 to pull out the railing 41, making it convenient for the rescuer to take out the pull rope 40. The above function solves the problem of traditional equipment that a third party cannot easily and quickly pull the pull rope 40 to pop out the lifebuoy 52 when someone needs to be rescued.

[0046] When in use, start the motor fixedly connected to one end of the screw rod 30. The rotation of the motor drives the screw rod 30 to rotate. The screw rod 30 drives the inner screw block 33. The inner screw block 33 drives the shaft rod 34 to move toward the two ends of the bridge body 1. The shaft rod 34 drives the plow-shaped scraper 35. The plow-shaped scraper 35 slides inside the drainage trough 31 to discharge the internal dirt. The above functions solve the problem that traditional equipment cannot clean the dirt inside the drainage trough 31.

[0047] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative work should fall within the scope of protection of the present invention.
