[0027] like Figure 1 to Figure 7 As shown, a highway flood bridge with self-sensing and self-adaptive functions of the present invention comprises a bridge deck 2, a plurality of bridge piers 1 are arranged below the bridge deck 2, installation foundations are arranged on the outer sides of both ends of the bridge deck 2, the installation foundations include a road surface installation foundation 3 and a lifting foundation 4, it should be noted that the installation foundation is connected to the road surface on both sides of the river bank so that it is fixed to the road surface, the lifting foundation 4 is symmetrically arranged on both sides of the road surface installation foundation 3 facing one end of the bridge deck 2, a hanger 5 is arranged on the lifting installation foundation, one end of the hanger 5 is fixed on the lifting foundation 4, a lifting device 6 is arranged above the other end of the hanger 5, the lifting device 6 is fixed on the end of the hanger 5, and a lifting ear 10 is arranged on the outer side of the end of the bridge deck 2, and a lifting rope 8 of the lifting device 6 is connected to the lifting ear 10 A column 9 is also provided on the lifting ear 10, one end of the column 9 is fixed to the upper end of the hanger 5, and the other end of the column 9 is plugged and fixed in the riverbed. The lifting ear 10 is slidably connected to the column 9, and a water level monitoring sensor 11 is provided on the column 9. The water level monitoring sensor 11 is used to monitor the height of the water in the river channel. When the water level monitoring sensor 11 detects that the water depth in the river channel exceeds a preset threshold, the water level monitoring sensor 11 transmits a lifting signal to the lifting device 6, and the lifting device 6 receives the lifting signal and lifts the bridge deck 2 upward. When the water level monitoring sensor 11 detects that the water depth in the river is lower than the preset threshold, the water level monitoring sensor 11 sends a descending signal to the lifting device 6, and the lifting device 6 receives the lifting signal and slowly lowers the bridge deck 2 downward.

[0028] The working principle of the above technical solution is:

[0029] When the water level monitoring sensor 11 detects that the water depth in the river is about to submerge the bridge deck 2, the water level monitoring sensor 11 controls the lifting device 6 to work, and the lifting device 6 lifts the bridge deck 2 upward to prevent the bridge deck 2 from being submerged and impacted by water. When the water level monitoring sensor 11 detects that the water level has dropped to a normal depth, the lifting device 6 resets the bridge deck 2. This setting method can adaptively adjust the height of the bridge deck 2 according to the water depth, avoid the bridge deck 2 from being submerged and impacted by water, and improve the protection effect of the bridge deck 2. It should be noted that the lifting equipment is a prior art. In this specific embodiment, a winch is used, and the lifting rope 8 is wound around the winding wheel 7. It can also be set with reference to the lifting method of the elevator, and no further elaboration is made here. The water level monitoring sensor 11 can be a magnetic float sensor or a pressure diaphragm sensor, and no further elaboration is made here. At the same time, the setting of the column 9 can enhance the stability of the bridge deck 2 after it is lifted.

[0030] In one feasible manner, an infrared recognition sensor 12 is provided at the upper end of the hanger 5. The infrared recognition sensor 12 is used to detect whether there are pedestrians on the bridge deck 2. When there are no pedestrians on the bridge deck 2 and the lifting device 6 receives a lifting signal, the lifting device 6 will lift the bridge deck 2. The infrared recognition sensor 12 can detect whether there are pedestrians on the bridge deck 2 to avoid the problem that there are still pedestrians on the bridge deck 2 when the bridge deck 2 is lifted, which may cause danger to the pedestrians.

[0031] In one feasible manner, multiple thresholds are preset in the water level monitoring sensor 11, each threshold corresponds to a different monitored water depth, and the water level monitoring sensor 11 sends different lifting signals to the lifting device 6 according to the different thresholds, and each lifting signal controls the lifting device 6 to lift the bridge deck 2 to different heights.

[0032] For example, the height of the bridge deck 2 is set to 3m. When the water depth is 2.7m, the bridge deck 2 is raised by 30cm. When the water depth is 3m, the bridge deck 2 is raised to 3.6m, and so on. The advantage of this is that while keeping the height between the bridge deck 2 and the water surface within a safe range, it can also avoid raising the bridge deck 2 too high at one time, resulting in the problem of excessive wind force.

[0033] In one practicable manner, a mounting groove 14 is provided in the middle of one end of the pavement mounting base 3 facing the bridge deck 2, and the mounting groove 14 is arranged through one end of the bridge deck 2, and a slide groove 15 is symmetrically provided on the upper part of the mounting groove 14, and a slide rod 16 is provided in the slide groove 15, and both ends of the slide rod 16 are slidably connected in the slide groove 15. It is not difficult to understand that the end of the slide rod 16 can only slide and cannot deflect in the slide groove 15. The specific implementation method can be achieved by the roller being located in the card groove. No more details are given here. A rotating plate 18 is provided on the slide rod 16, and one end of the rotating plate 18 is provided A through hole 19 is sleeved on the slide bar 16. A support block 17 is provided on the bottom surface of the end of the mounting groove 14 facing the bridge deck 2. The support block 17 and the slide bar 16 support the rotating plate 18 in the normal state to ensure the flatness of the rotating plate 18 and the road surface. When the rotating plate 18 is placed on the support block 17, the rotating plate 18 is flush with the upper surface of the road surface mounting base 3. The end of the rotating plate 18 facing the bridge deck 2 is connected to the upper surface of the end of the bridge deck 2. When the bridge deck 2 is lifted upward, the bridge deck 2 drives the rotating plate 18 to rotate and drives the slide bar 16 to move in the slide groove 15.

[0034] The working principle of the above technical solution is:

[0035] When the bridge deck 2 is lifted upward, the bridge deck 2 applies an upward force to the end of the rotating plate 18, and the rotating plate 18 will rotate and tilt. When the bridge deck 2 continues to be lifted upward, the bridge deck 2 will pull the sliding rod 16 to move closer to the bridge deck 2 in the sliding groove 15. It is not difficult to understand that the rotating plate 18 is in an inclined state at this time, and one end of the rotating plate 18 is supported by the sliding rod 16, and the other end is connected to the bridge deck 2. Therefore, the rotating plate 18 connects the road surface and the bridge deck 2 at this time. The rotating plate 18 can be understood as an inclined lap plate. At this time, pedestrians can walk onto the bridge deck 2 through the rotating plate 18, and walk from the bridge deck 2 to the road surface through the rotating plate 18, which ensures the safety of pedestrians passing through the bridge deck 2 during flooding and improves the passability of the flooded bridge. It is not difficult to understand that if pedestrians pass through the flood bridge in flood weather, the water flow can easily push pedestrians into the river, causing danger. If the flood bridge is lifted, although the safety of the bridge deck 2 is guaranteed, pedestrians cannot pass normally, causing great inconvenience to pedestrians. Therefore, the setting method in this technical solution ensures the passability of the flood bridge after it is lifted. Of course, the premise of passing is that the height difference between the water surface and the road surface is at a distance that pedestrians can pass safely.

[0036] In one practicable manner, fixed blocks 30 are symmetrically provided at the upper surface edges of the ends of the rotating plate 18 and the upper surface edges of the ends of the bridge deck 2, and connecting rods 13 are provided on the rotating plate 18 and the two fixing blocks 30 arranged opposite to each other on the bridge deck 2, and the two ends of the connecting rod 13 are respectively rotatably connected to the upper ends of the two fixing blocks 30. This method of connecting the rotating plate 18 and the bridge deck 2 can drive the rotating plate 18 to tilt when the bridge deck 2 is lifted, and of course, it can also be directly connected by steel cables.

[0037] In one feasible manner, an installation cavity 20 is provided on the road surface installation base 3 above the end of the installation groove 14 away from the bridge deck 2. The installation cavity 20 is flush with and connected to the slide groove 15. A slide plate 21 is provided in the installation cavity 20. A plurality of first connecting seats 29 are provided on the end of the slide plate 21 facing the installation groove 14. One end of the first connecting seat 29 is fixed on the slide plate 21. A rotating shaft 22 is provided on the other end of the first connecting seat 29. A plurality of second connecting seats 24 are provided on the end of the rotating plate 18 away from the bridge deck 2. One end of the second connecting seat 24 is fixed on the rotating plate 18. The other end of the second connecting seat 24 is rotatably connected to the rotating shaft 22.

[0038] The working principle of the above technical solution is:

[0039] When the slide bar 16 moves toward the bridge deck 2, the end of the rotating plate 18 is also driven to move toward the bridge deck 2, that is, the rotating plate 18 will pull the slide plate 21 to move, that is, the slide plate 21 extends outward to fill and block the gap after the end of the rotating plate 18 moves, so as to prevent pedestrians from falling into the installation groove 14 and causing unnecessary danger. At the same time, the slide plate 21 and the end of the rotating plate 18 are rotatably connected, that is, they will not interfere with the rotation of the rotating plate 18. It is not difficult to understand that the end of the rotating plate 18 can be chamfered or a gap is reserved between the end of the slide plate 21 to avoid blocking interference when the rotating plate 18 rotates. The method of avoiding interference is a well-known technology well known to those skilled in the art, and will not be described in detail here.

[0040] In one practicable manner, a plurality of first springs 23 are provided on the other end of the skateboard 21, one end of the first spring 23 is fixed on the end of the skateboard 21, and the other end of the first spring 23 is fixed on the side wall of the mounting cavity 20 away from the bridge deck 2. The first springs 23 are arranged so that when the skateboard 21 moves outward, the first springs 23 will be pulled by the rope, and when the bridge deck 2 descends, the first springs 23 are reset to drive the skateboard 21 and the slide rod 16 to move, thereby achieving the purpose of auxiliary reset.

[0041] In one feasible manner, a plurality of slidingly arranged telescopic plates 28 are provided on the rotating plate 18, and a metal bottom plate 26 is provided on one end of the telescopic plate 28 facing the mounting groove 14, and the metal bottom plate 26 is fixed on the end of the telescopic plate 28, and a plurality of second springs 27 are provided between the telescopic plate 28 and the rotating plate 18, and one end of the second spring 27 is fixed on the rotating plate 18, and the other end of the second spring 27 is fixed on the metal bottom plate 26. An electromagnet 25 is provided in the mounting groove 14, and the electromagnet 25 is used to control the adsorption state of the metal bottom plate 26. When the bridge deck 2 is on the pier 1, the electromagnet 25 adsorbs the metal bottom plate 26. At this time, the upper end of the telescopic plate 28 is arranged flush with the rotating plate 18. When the bridge deck 2 is lifted, the electromagnet 25 is separated from the adsorption of the metal bottom plate 26. The working state of the electromagnet 25 can be controlled by sending a control signal through the water level monitoring sensor 11. It is not difficult to understand that the electromagnet 25 should be waterproof.

[0042] The working principle of the above technical solution is:

[0043] When the bridge deck 2 and the rotating plate 18 are in normal state, the electromagnet 25 works to adsorb the metal bottom plate 26 onto the electromagnet 25. At this time, the second spring 27 is in a rope-pulling state, that is, the other end of the telescopic plate 28 is flush with the rotating plate 18, which will not affect the passability of pedestrians. When the bridge deck 2 is lifted, the electromagnet 25 is powered off, that is, the second spring 27 is reset, and the other end of the telescopic plate 28 is pushed out onto the surface of the rotating plate 18, that is, the telescopic plate 28 protrudes from the rotating plate 18. That is, when the rotating plate 18 is tilted, the protruding telescopic plate 28 can serve as a step, allowing pedestrians to walk on the rotating plate 18 more easily, which can achieve the purpose of anti-slip and is safer to use.

[0044] It should be noted that, in the present technical solution, the principle of how to control the operation of the lifting device 6 and the electromagnet 25 through the water level monitoring sensor 11 is an existing technology, and its electrical connection method is also an existing technology, which will not be elaborated on here. At the same time, in the present technical solution, when the setting length of the rotating plate 18 is relatively long, its inclination after rotation is small, which can also meet the traffic conditions of vehicles.

[0045] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
