In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0029] It can be understood that as a building heritage, the load-bearing characteristics of the main structure of the wooden corridor bridge have distinct features. Therefore, it is not appropriate to improve the flood resistance of the bridge body 11 by adding components, and only the flood discharge aspect can be considered. Therefore, studying a flood discharge method for the wooden corridor bridge is of extremely important practical significance for protecting precious wooden corridor bridge cultural relics, continuing historical and cultural memories, and reducing flood losses.

[0030] Please refer to Figures 1 to 4 According to the embodiment of the present invention, the wooden corridor bridge with a flood discharge function includes a corridor bridge body 1, a first baffle 2, a driving component, and a control system. The corridor bridge body 1 forms a bridge opening, and a fixed baffle 13 is provided above the bridge opening. The fixed baffle 13 is provided with a first flood discharge opening 131; the first baffle 2 is rotatably connected to the fixed baffle 13, and the first baffle 2 is adapted to open or close the first flood discharge opening 131; the driving component is arranged on the corridor bridge body 1 or the fixed baffle 13, and the driving component is connected to the first baffle 2 to drive the first baffle 2 to rotate to open or close the first flood discharge opening 131; the control system is arranged on the corridor bridge body 1 and is electrically connected to the driving component to control the rotation of the first baffle 2.

[0031] For the wooden corridor bridge with a flood discharge function according to the embodiment of the present invention, by opening the first flood discharge opening 131 in the area of the fixed baffle 13 without the load-bearing structure 14, the flood discharge capacity of the wooden corridor bridge is improved. In this way, the modification of the load-bearing structure 14 of the wooden corridor bridge is avoided, the load-bearing mechanism of the wooden corridor bridge is retained, and only a part of the fixed baffle 13 is modified, which conforms to the principle of minimum intervention. By controlling the driving component through the control system to drive the first baffle 2 to open the first flood discharge opening 131, the water passing area under the bridge can be increased to a large extent, and the flood impact on the corridor bridge body 1 can be reduced. When flood discharge is not required, the first baffle 2 closes the first flood discharge opening 131, improving a certain structural strength and maintaining the traditional appearance of the corridor bridge. The structure of the present invention is ingenious, has strong environmental adaptability, can work stably in the complex water area environment under the bridge, and has strong reliability.

[0032] It is understandable that the first baffle 2 can be rotated by a hinge structure or a rotating shaft structure, and the driving component is a power device for realizing the rotation function of the first baffle 2. Its structure can be a motor and gear structure, or a driving structure such as a cylinder or an oil cylinder, which is not limited here, as long as it can drive the first baffle 2 to rotate relative to the fixed baffle 13. It should be noted that the driving component should have a waterproof function to adapt to working in an underwater environment.

[0033] like Figure 2 and Figure 3 As shown, in one embodiment, the corridor bridge body 1 includes a bridge body 11 and a corridor house 12. A load-bearing structure 14 is set up in the middle of the bridge body 11 to form a bridge hole. The corridor house 12 is located above the bridge body 11 to achieve the function of rain protection. The load-bearing structure 14 is mainly woven from a number of round timbers, such as three-section seedlings, five-section seedlings, bridge deck seedlings, scissors braces, frog legs, etc. The load-bearing structure 14 is a prior art and will not be described here. Fixed baffles 13 are installed on both sides of the load-bearing structure 14 to form the lower wooden arch bridge system of the wooden corridor bridge. Optionally, according to the density of the round timbers behind the fixed baffles 13, the fixed baffles 13 are divided into Class A areas and Class B areas and installed separately. Among them, the distribution of round timbers behind the Class A area is relatively dense, so the baffles in the Class A area are installed on the load-bearing structure 14 using fixed constraints, while there are no round timbers behind the baffles in the Class B area, so a first flood discharge outlet 131 is opened, and a metal loose-leaf is used to connect the first baffle 2. In this way, after the first baffle plate 2 rotates relative to the fixed baffle plate 13, a larger bridge hole space can be exposed, thereby increasing the water flow area of ​​the wooden corridor bridge.

[0034] like Figure 3 As shown, according to one embodiment of the present invention, the control system includes a water level sensor, which is arranged on the corridor bridge body 1 and is used to monitor the water level. In this embodiment, the control system integrates a water level sensor, a Hall sensor and an operation panel, wherein the water level sensor is used to monitor the water level, and the control system can also control the folding and resetting of the first baffle 2 according to the water level data monitored by the water level sensor. For example, when the water level reaches the position of the first baffle 2, the first baffle 2 is controlled to open the first flood discharge port 131, and when the water level drops below the first baffle 2, the first baffle 2 is controlled to close the first flood discharge port 131. The operation panel of the control system supports manual and automatic mode switching, that is, the control system can manually control the first baffle 2 to open or close, and can also automatically open or close the first baffle 2 by monitoring the water level change, thereby improving intelligence. Optionally, the control system can be installed in the corridor house 12, and the corridor house 12 can play a certain protective role to reduce the risk of damage to the control system.

[0035] Please refer to Figure 3 and Figure 4According to one embodiment of the present invention, the first baffle 2 is rotated from the fixed baffle 13 toward the direction of the corridor bridge body 1 to open the first flood discharge port 131. It can be understood that the first baffle 2 is turned toward the inner side of the corridor bridge body 1, that is, it is turned along the flow direction of the flood. In this way, the protection of the first baffle 2 can also prevent floating objects in the flood from accumulating inside the corridor bridge body 1, further ensuring the smooth flood discharge of the wooden corridor bridge.

[0036] According to one embodiment of the present invention, the rotation angle of the first baffle 2 relative to the fixed baffle 13 is 0° to 90°. That is, when the first baffle 2 is rotated 90°, the first baffle 2 is perpendicular to the fixed baffle 13, thereby increasing the water flow area of ​​the bridge hole, and the folded first baffle 2 can form a flood diversion barrier to prevent the accumulation of flood floating objects here.

[0037] Please refer to Figure 2 and Figure 5 According to one embodiment of the present invention, the corridor bridge body 1 is provided with a load-bearing structure 14, and the load-bearing structure 14 includes a plurality of load-bearing rods 141, and the plurality of load-bearing rods 141 are arranged at intervals along the width direction of the corridor bridge body 1. A plurality of card slots 21 are provided on one side of the first baffle plate 2. When the first baffle plate 2 is rotated to open the first flood discharge outlet 131, each card slot 21 is connected to a load-bearing rod 141.

[0038] It can be understood that the first baffle 2 is provided with a plurality of slots 21 on the side away from the flood flow direction. After the first baffle 2 is rotated 90°, the plurality of slots 21 form a sawtooth structure to be locked on the load-bearing rod 141, thereby ensuring the discharge of flood water and improving the overall lateral force resistance of the wooden bridge. In other words, after the first baffle 2 is rotated, it can be supported on the load-bearing structure 14, ensuring its own stability, reducing the risk of being washed away by flood water, and improving the overall structural strength of the wooden bridge.

[0039] According to one embodiment of the present invention, the driving assembly includes a driving unit and a transmission mechanism, the transmission mechanism includes a slide rail 31 and a telescopic rod 32, the slide rail 31 is arranged on the first baffle 2, one end of the telescopic rod 32 is hinged with a slider 321, the slider 321 is slidably connected to the slide rail 31, the telescopic rod 32 is connected to the driving unit, and the driving unit drives the telescopic rod 32 to extend and retract, so that the slider 321 slides along the slide rail 31, thereby driving the first baffle 2 to rotate relative to the fixed baffle 13.

[0040] In this embodiment, the drive unit is located in the gallery 12 and is composed of a small hydraulic cylinder or electric push rod to provide power for the rotation of the first baffle 2. Exemplarily, the drive unit is connected to the telescopic rod 32 through a hydraulic oil pipe 33 to drive the telescopic rod 32 to extend and retract. When the telescopic rod 32 is extended and retracted, the slider 321 moves accordingly on the slide rail 31, and the telescopic rod 32 pushes the first baffle 2 to rotate relative to the fixed baffle 13. The drive unit is preferably a low-power hydraulic pump station (rated pressure 6-10MPa, flow rate 5-8L / min), and the pump station host is connected to the telescopic rod 32 through a pre-buried hydraulic oil pipe 33.

[0041] According to one embodiment of the present invention, a sleeper is provided at the bottom of the bridge body 1 located at the bridge hole, and the bridge body 1 is provided with a three-section seedling structure 15, one end of the three-section seedling structure 15 is supported on the sleeper, one end of the telescopic rod 32 away from the slider 321 is supported on the sleeper, and a bayonet is provided at one end of the telescopic rod 32 away from the slider 321, and one end of the three-section seedling structure 15 is at least partially accommodated and confined in the bayonet.

[0042] It should be noted that one end of the three-section seedling structure 15 is supported on the sleeper, and its ability to resist lateral forces is relatively weak, that is, the three-section seedling structure 15 is easy to move or deform along the length direction of the sleeper. For this reason, the bottom of the telescopic rod 32 is supported on the sleeper, and a bayonet is provided to clamp one end of the three-section seedling structure 15, that is, one end of the three-section seedling structure 15 is connected to the sleeper and is limited in the bayonet of the telescopic rod 32, so as to limit the lateral displacement of the three-section seedling structure 15 and improve the stability of the bridge body 11. It should be noted that Figure 5 The structure shown is only a schematic representation and does not represent the actual size.

[0043] According to an embodiment of the present invention, a Hall sensor is provided at one end of the telescopic rod 32 adjacent to the slider 321 for detecting the rotation angle of the first baffle 2 , thereby ensuring that the first baffle 2 is rotated into place.

[0044] For example, the operation panel is embedded in the inner side of the bridge railing, 1.2m above the bridge deck, and has functional modules such as displaying real-time water level, baffle angle and fault code, as well as physical knobs with three gears of lock / expand / retract. The water level sensor uses an ultrasonic water level meter (range 0-5m, accuracy ±1cm) installed on the water-facing surface of the wooden bridge, 2.5m above the normal water level. The state detection of the first baffle 2 uses a Hall sensor embedded in the drive assembly, and the rotation angle of the first baffle 2 is marked by a magnet (0°→90° division).

[0045] Operation sequence during flood season: Step 1: The water level sensor detects that the water level has reached the warning line (e.g. 2.5m), and sends a level 1 alarm to the operation panel; Step 2: After confirmation by the administrator, unlock the mechanical lock through the operation panel (the electromagnetic lock is powered off and released); Step 3: Select the automatic mode, start the driving unit, and the first baffle 2 flips 90° inward towards the inner side of the bridge body 11 within 12 seconds; Step 4: After the first baffle 2 is fully deployed, the control system automatically switches to the monitoring state, and collects water level and angle data of the first baffle 2 every 30 seconds; Step 5: After the water level drops to the safety line, the panel prompts "retract", and reverse operation is performed to reset the first baffle 2 and relock it.

[0046] As Figure 3 shown, according to an embodiment of the present invention, the fixed baffle 13 is provided with two first flood discharge openings 131, and the two first flood discharge openings 131 are symmetrically arranged about the central axis of the fixed baffle 13. Each flood discharge opening is provided with a first baffle 2 and a driving component. It can be understood that the two first flood discharge openings 131 are symmetrically arranged, and when discharging flood, the two ends of the corridor bridge body 1 are evenly stressed, improving the structural stability.

[0047] According to an embodiment of the present invention, the fixed baffle 13 is provided with a second flood discharge opening 132. The second flood discharge opening 132 is spaced from the first flood discharge opening 131 in the height direction. The wooden corridor bridge with flood discharge function includes a second baffle 6. The second baffle 6 is rotatably connected to the fixed baffle 13. The second baffle 6 is adapted to open or close the second flood discharge opening 132. The driving component is connected to the second baffle 6 to drive the second baffle 6 to rotate to open or close the second flood discharge opening 132.

[0048] It can be understood that as the water level rises, the first baffle 2 and the second baffle 6 can be gradually opened to gradually improve the flood discharge capacity. It should be noted that the first baffle 2 can be arranged above the second baffle 6, or the second baffle 6 can be arranged above the first baffle 2, which is not limited herein. The structure at the second baffle 6 is the same as or similar to the structure at the first baffle 2, and will not be described in detail herein. The difference lies in the different shapes set at different positions of the bridge body 11. For example, the first flood discharge opening 131 and the first baffle 2 are rectangular, and the second flood discharge opening 132 and the second baffle 6 are triangular to adapt to the arch bridge shape.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered by the scope of the claims of the present invention.
