Roll-up flood barrier

Abstract

This invention discloses a rollable flood barrier, comprising at least five vertical panels and corresponding base and support plates. The vertical panels are inverted trapezoids, and the base plates are rectangular. The shorter parallel sides of the vertical panels are fixedly connected to the longer sides of the base plates, and the panel surfaces are perpendicular to each other, forming an "L" shape. The base plates are hinged together in a track-like pattern, with the hinge axis perpendicular to the vertical panels. The shorter sides of the base plates decrease in length, and adjacent vertical panels are staggered. The vertical panels and corresponding base plates can be rolled into regular polygons. Support plates connect the base and vertical panels, enhancing the stability of the vertical panels. This invention is used for sealing gaps at the intersection of roads and flood control dikes, offering advantages such as good adaptability, small footprint, simple operation, and rapid response.

Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering and relates to a flood barrier, particularly a retractable flood barrier. Background Technology

[0002] In flood control dikes or flood walls, gaps are often left at the intersections of roads and dikes due to traffic needs. Entrances to underground parking garages also present flood control gaps. These gaps are normally left open but need to be sealed during floods. Sealing methods typically involve floodgates or flood barriers. Flood barriers are currently available in detachable and movable types. Detachable flood barriers are more effective but are more expensive, slower to install, and inconvenient to store materials, failing to meet the requirements for rapid response during floods. Movable flood barriers cannot accommodate vehicle traffic.

[0003] Existing patented technologies, such as patent technology with application number CN201610342714 (publication date 2016.10.12), patent technology with application number CN201520422959 (publication date 2015.11.11), and patent technology with application number CN2019204223416 (application date 2019.3.31), all use flip-up flood barriers. However, because the load-bearing capacity of the flood barriers is insufficient, they are not suitable for use in places with vehicle traffic requirements. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a rollable flood barrier that can conveniently solve the problem of sealing flood control gaps with traffic requirements, and overcomes the disadvantage of existing patented technologies that cannot accommodate vehicle traffic.

[0005] This invention is achieved through the following technical solution: The roll-up flood barrier includes at least five vertical panels and corresponding base plates. The vertical panels are inverted trapezoids, and the base plates are rectangular. The shorter parallel sides of the vertical panels are fixedly connected to the longer sides of the base plates, and the panel surfaces are perpendicular to each other, forming an "L" shape. The base plates are hinged together in a track-like manner, with the hinge axis perpendicular to the vertical panels. The vertical panels and corresponding base plates can be rolled into regular polygons.

[0006] The short side length of the base plate decreases progressively, and the positions of adjacent upright plates are staggered.

[0007] The upright plate is equipped with vertical water-stop strips and fan-shaped water-stop plates, and the upright plate is provided with clamping bolt holes and support bolt holes.

[0008] The base plate is equipped with a pair of support plates, which are hinged to the base plate by a pin assembly. They can rotate from 0° to 90°, and the two support plates rotate in opposite directions. When the support plate is at 0°, it is in contact with the base plate. When the support plate is at 90°, it is perpendicular to both the base plate and the upright plate, and is fixed to the upright plate by bolts.

[0009] The clamping bolt holes are located on both sides of the water-stop strip, one side being a circular hole and the other side being an arc-shaped hole centered on the hinge axis.

[0010] The materials used for the uprights, base plate, and support plate are steel, aluminum alloy, or plastic.

[0011] The uprights, base plate, and support plate are manufactured and assembled in the factory, rolled into pentagons, and transported to the side of the breach in the flood control wall. When a flood comes, the flood control plate is unfolded in a line to seal the breach.

[0012] In summary, compared with the prior art, the beneficial effects of the present invention are: the flood barrier can be placed outdoors on-site without the need for a supporting material storage room; the installation does not require guide rails or special bottom sills; it can adapt to changes in ground slope; the flood barrier can be easily unfolded and retracted by manpower; and it is simple and quick to use.

[0015] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1-6 As shown, a specific embodiment of a roll-up flood barrier is provided, comprising five vertical plates 1 and corresponding base plates 2, which can be rolled into a regular pentagon. The vertical plates 1 and support plates 3 are made of 4mm thick steel plates, while the base plates 2 are made of 6mm thick steel plates. The vertical plates 1 are trapezoidal with interior angles of 108° and 72°, a base width of 1.5m, a top width of 2.28m, and a height of 1.2m, i.e., a water-blocking height of 1.2m. The base plates 2 are rectangular, with a length of 1.5m and a width of 0.9m-1.0m. The vertical plates 1 and base plates 2 are welded perpendicularly, and the base plates are hinged together by hinges 21.

[0017] Furthermore, the upright plate 1 is equipped with a fan-shaped water-stop rubber plate 12 and a water-stop rubber strip 11 at the position above the hinge 21. The two adjacent upright plates can be clamped together with bolts through the clamping bolt holes 13 to achieve the water-stopping effect.

[0018] Furthermore, one end of the support plate 3 is hinged to the base plate 2 via the pin assembly 22, and the other end is bent up at 90°. The bent part has screw holes that correspond to the support bolt holes 14 of the upright plate 1. When the support plate 3 rotates to fit against the base plate 2, the bent part does not obstruct the rotation of the adjacent upright plates. The pin assembly 22 connecting the support plate 3 is fixed to the base plate 2 by bolts and welding.

[0019] The working process in this embodiment is as follows: The roll-up flood barrier is manufactured in the factory and rolled into a regular pentagonal shape. It weighs 750kg in total. It is transported to the side of the gap in the flood wall and placed next to it. It occupies 1.0m×1.5m and has a height of 2.34m. It does not affect vehicle passage at the gap, does not damage the road surface, and has minimal impact on surrounding facilities.

[0020] When the flood level rises to the gap, a foam pad with the same width as the base plate 2 is laid on the ground at the gap. Then, the flood barrier is unfolded one by one along the foam pad. After that, the support plate 3 is erected and fixed to the upright plate 1 to enhance stability. The water-stop strip 11 and the fan-shaped water-stop plate 12 are clamped with bolts through the clamping bolt holes 13 of the adjacent upright plates to connect the 5 upright plates and the base plate into a whole. The first and last upright plates are connected to the flood control walls on both sides of the gap to seal the gap.

[0021] Because the clamping bolt hole 13 has an arc shape, it can adapt to slight changes in the clamping angle of the base plate 2, so that the flood barrier can adapt to changes in the cross slope of the road after it is unfolded.

[0022] In this embodiment, the flood barrier can seal a 5.5m wide flood control breach after being deployed. Because the deployment of the flood barrier is a rotational action, it can be easily accomplished manually.

[0023] When blocking water, the flood control plate maintains its stability by its own weight and the water pressure on the bottom plate 2.

[0024] After the flood, the bolts on the upright plate 1 and the support plate 3 are removed, the support plate is rotated to fit snugly against the base plate 2, and then the upright plate and the base plate are rolled up piece by piece into a regular pentagon and placed next to the notch for future use. Because the entire rolling action is a rotational action, it can be easily completed manually.

[0025] The above embodiments are specific embodiments of the present invention and are not intended to limit the present invention. Without departing from the concept of the present invention, any obvious extensions and substitutions, such as using more than 6 upright plates 1 to form a regular polygon with more than 6 sides, and using a fixed type for the support plate 3, are all within the protection scope of the present invention.
