Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering, in particular to a guardrail for a flooded bridge. Background Art

[0002] Guardrails for flooded bridges usually refer to guardrails installed on both sides of the bridge or on the edge of the bridge deck to ensure the safety of pedestrians and vehicles and prevent them from accidentally falling from the edge of the bridge. Such guardrails are generally made of materials such as metal, concrete or plastic, have certain strength and stability, and can withstand certain impact and pressure. However, the existing guardrails for flooded bridges still have the following problems in actual use:

[0003] Patent No. "CN202222429080.5" discloses a movable guardrail for a flooded bridge. When the device is in use, the upper inner diameter of the fixing hole is larger than the lower inner diameter of the fixing hole, the outer end outer diameter of the end head is larger than the inner end outer diameter of the end head, the outer end outer diameter of the end head is larger than the lower inner diameter of the fixing hole and smaller than the upper inner diameter of the fixing hole, and the inner end outer diameter of the end head is larger than the lower inner diameter of the fixing hole. During installation, the end head is inserted into the column along the upper part of the fixing hole. When the inner end of the end head moves into the fixing hole, the end head moves downward along the fixing hole by relying on the self-weight of the baffle, so that the inner end of the end head is placed on the lower part of the fixing hole. At this time, since the outer diameter of the outer end of the end head is larger than the lower inner diameter of the fixing hole, the outer end of the end head plays a limiting role to prevent the end head from being separated from the fixing hole. During use, the device cannot timely know the current water flow speed during use, resulting in safety hazards in the actual use of the device, resulting in poor safety of the device. At the same time, the device cannot accurately determine the specific height of the water surface during use, so that pedestrians cannot know the water surface height when they need to cross the bridge, resulting in reduced safety of the device and poor practicality. Utility Model Content

[0004] The utility model aims to solve the above-mentioned problem and proposes a guardrail for a flooded bridge, which improves the problems of poor safety and poor practicality of the existing guardrails for flooded bridges.

[0011] The beneficial effects of the utility model are:

[0012] 1. A flow rate detection mechanism is provided. During use, the water flow impacts the side of the first paddle, thereby driving the rotating rod to rotate. During the rotation of the rotating rod, the second paddle is also driven to rotate. At this time, pedestrians can observe the rotation speed of the second paddle. When the second paddle rotates slowly, it means that the water flow speed is slow at this time, and it is safer to cross the bridge at this time. When the second paddle rotates quickly, the whistle set on the side of the second paddle rotates too fast and makes a sound to remind pedestrians, indicating that the water flow speed is fast at this time, which is very dangerous and not suitable for crossing the bridge;

[0013] 2. A water depth detection mechanism is provided. When the water surface is deep, the buoyancy of the water pushes the float block to slide up on the inside of the slide groove. When the float block pushes the slider to squeeze the telescopic column to extend, the reflective strip is extended during the extension of the telescopic column to warn pedestrians. At this time, the water surface is high and the risk factor of crossing the bridge is high, thereby improving the safety of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] When implementing: Figure 1-7 As shown, a guardrail for a flooded bridge comprises: a bridge body 1, a supporting mechanism 3, a protective mechanism 4, a flow velocity detection mechanism 5, a column 6 and a water depth detection mechanism 7. A bridge deck 2 is arranged at the upper end of the bridge body 1, a supporting mechanism 3 is arranged at the upper end of the bridge deck 2, and columns 6 are symmetrically arranged at the upper end of the bridge deck 2. A protective mechanism 4 is connected between the supporting mechanism 3 and the column 6. The protective mechanism 4 is rotatably connected to the flow velocity detection mechanism 5, and the column 6 is slidably connected to the water depth detection mechanism 7. When the device is in use, firstly, preliminary protection is performed by the supporting mechanism 3 and the protective mechanism 4 during use. At the same time, the flow velocity detection mechanism 5 can be used to check whether the water flow speed is suitable for walking during use, thereby improving the safety of the device. At the same time, the water depth detection mechanism 7 set during use can remind pedestrians of the current height of the flooded bridge being submerged by water during the use of the device, so that pedestrians can observe whether it is suitable to cross the bridge at this time, thereby improving the overall safety of the device.

[0024] The supporting mechanism 3 includes a base 31, a positioning bolt 32, a connecting column 33, a first guide plate 34 and a decorative block 35. The base 31 is symmetrically arranged on the upper end of the bridge deck 2. The base 31 is threadedly connected with the positioning bolt 32. The upper end of the base 31 is connected to the connecting column 33. The first guide plate 34 is arranged on the side of the connecting column 33. The decorative block 35 is arranged on the upper end of the connecting column 33. When the device is in use, the connecting column 33 is positioned by the positioning bolt 32. At the same time, the first guide plate 34 arranged on the side of the connecting column 33 can disperse the impact force of the water flow on the connecting column 33 to both sides of the first guide plate 34, thereby reducing the impact force of the water flow on the connecting column 33 and improving the service life of the device.

[0025] The protection mechanism 4 includes a positioning plate 41, a protection plate 42 and a protection column 43. The positioning plate 41 is connected to the side of the connecting column 33. Two protection plates 42 are symmetrically arranged on the side of the connecting column 33. The protection columns 43 are equidistantly connected to the protection plates 42. The sides of the positioning plate 41 and the protection plate 42 are both connected to the column 6. When the device is in use, it is protected by the transversely connected positioning plate 41 and the protection plate 42, and then protected by the longitudinally connected protection column 43, thereby improving the protection safety of the device.

[0026] The flow rate detection mechanism 5 includes a rotating rod 51, a first paddle 52 and a first filter 53. The bridge deck 2 is rotatably connected to the rotating rod 51, the rotating rod 51 is rotatably connected to the positioning plate 41 and the protective plate 42, the side of the rotating rod 51 is rotatably connected to the first paddle 52, the side of the first paddle 52 is provided with a first filter 53, and the first filter 53 is provided on the upper surface of the bridge deck 2.

[0027] A second guide plate 54 is connected between the column 6 and the first filter screen 53, and a second paddle 55 is arranged at an equal angle on the side of the rotating rod 51, and a second filter screen 56 is arranged on the side of the second paddle 55. The second filter screen 56 is arranged on the upper end of the positioning plate 41. When the device is in use, water hits the side of the first paddle 52 on the inner side of the first filter screen 53 through the second guide plate 54, and the rotating rod 51 is driven to rotate by the first paddle 52. During the rotation of the rotating rod 51, the second paddle 55 is also driven to rotate. Pedestrians can observe the rotation speed of the second paddle 55 before crossing the bridge. When the second paddle 55 rotates slowly, they can cross the bridge. When the second paddle 55 rotates faster, the risk is higher and it is not suitable to cross the bridge.

[0028] The water depth detection mechanism 7 includes a slide groove 71 , a limit plate 72 and a floating block 73 . The slide groove 71 is opened on the side of the column 6 , and the limit plate 72 is symmetrically arranged inside the slide groove 71 . The slide groove 71 is slidably connected to the floating block 73 .

[0029] A housing 74 is connected to the inner side of the slide groove 71 , a slider 75 is slidably connected to the housing 74 , and spring columns 76 are symmetrically arranged on the inner side of the housing 74 .

[0030] A telescopic column 77 is connected to the side of the shell 74, and a reflective strip 78 is connected to the protruding end of the telescopic column 77. When the device is in use, in deep water, the buoyancy pushes the float 73 to slide and rise inside the slide groove 71. When the float 73 pushes the slider 75 to squeeze the internal gas of the shell 74, the telescopic column 77 is pushed out. The extension of the telescopic column 77 also drives the reflective strip 78 to extend, thereby warning pedestrians not to cross the bridge at this time, thereby improving the safety of the device.

[0031] When the utility model is in use, the connection column 33 is first positioned by the positioning bolt 32, and at the same time, the first guide plate 34 arranged on the side of the connection column 33 can disperse the impact force of the water flow on the connection column 33 to both sides of the first guide plate 34, thereby reducing the impact force of the water flow on the connection column 33 and improving the service life of the device. At the same time, during use, the horizontally connected positioning plate 41 and the protective plate 42 are used for protection, and then the longitudinally connected protective column 43 is used for protection, thereby improving the protection safety of the device;

[0032] When water passes through the second guide plate 54 and hits the side of the first paddle 52 inside the first filter screen 53, the first paddle 52 drives the rotating rod 51 to rotate, and the rotating rod 51 drives the second paddle 55 to rotate at the same time during the rotation process. Pedestrians can observe the rotation speed of the second paddle 55 before crossing the bridge. When the second paddle 55 rotates slowly, they can cross the bridge. When the second paddle 55 rotates quickly, it is dangerous and it is not suitable to cross the bridge.

[0033] When the water is deep, the buoyancy pushes the float 73 to slide up inside the slide groove 71. When the float 73 pushes the slider 75 to squeeze the gas inside the shell 74, the telescopic column 77 is pushed out. The extension of the telescopic column 77 also drives the reflective strip 78 to extend, thereby warning pedestrians not to cross the bridge at this time, thereby improving the safety of the device.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
