[0014] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0015] A rapid drainage device for a road or bridge deck comprises a drainage bucket 1, a cover plate 2, an interception plate 3 and a water guide 4. The drainage bucket 1 is in a conical bucket shape that transitions from a rectangular shape to a circular shape from the water inlet side to the water outlet side. The lower end of the drainage bucket 1 is fixedly connected to an external drainage pipe. The interception plate 3 is detachably fixed and inserted into the bucket cavity of the drainage bucket 1. The cover plate 2 is detachably covered on the water inlet at the upper end of the drainage bucket 1. The cover plate 2 and the interception plate 3 are both grille plates. The grille bars in the cover plate 2 and the interception plate 3 are all in a single direction. The grille bars of the cover plate 2 and the grille bars of the intercepting plate 3 are perpendicular to each other in the top view, that is, the cover plate 2 and the intercepting plate 3 form a cross grid in the spatial direction, which intercepts impurities while reducing the probability of clogging. The water guide member 4 is detachably fixed in the drainage bucket 1, and the upper end of the water guide member 4 is clamped on the water outlet of the drainage bucket 1, and the lower end of the water guide member 4 is hung in the drain pipe. The water guide member 4 guides the direction of the discharged water flow, reduces the impact on the wall of the drainage pipe, and can reduce the generation of noise.

[0016] Two guide plates 11 are fixedly and vertically arranged in the bucket cavity of the drainage bucket 1. The two guide plates 11 are staggered along the diagonal direction. The end of the guide plate 11 close to the water outlet of the drainage bucket 1 is set to an arc shape and is arranged around the edge of the water outlet. Water flows into the drainage bucket 1 and is guided by the two guide plates 11. A vortex is formed at the water outlet and quickly flows into the drain pipe from the water outlet to be discharged, avoiding the situation where the water flows into the drainage bucket 1 quickly and covers the water outlet, causing the water flow and air pressure to collide and affect the discharge of the water flow.

[0017] The water guide member 4 includes an insertion block 41 and a water guide chain 42. The outer edge of the insertion block 41 is circular and has the same radial size as the water outlet of the drainage bucket 1. The insertion block 41 is interference fit and clamped on the water outlet of the drainage bucket 1. A water hole is opened axially on the insertion block 41. The water guide chain 42 is suspended on the lower end of the insertion block 41. The water guide chain 42 is made of rust-resistant material. After water flows through the water hole on the insertion block 41, it flows down along the water guide chain 42.

[0018] Working Principle: During road construction, the drainage bucket 1 is fixedly cast and installed at the point where drainage is required, and a drainage pipe is connected to the bottom of the drainage bucket 1. The water guide 4 is inserted into the water outlet of the drainage bucket 1, the intercepting plate 3 is inserted into the fixed drainage bucket 1, and the cover plate 2 is installed on the water inlet of the drainage bucket 1. This completes the assembly and installation of the device.

[0019] During drainage, water flows into the drainage bucket 1, and is guided by the guide plate 11 to form a vortex, which is quickly discharged into the drainage pipe from the water outlet. After the water flows through the insertion block 41, it will flow along the water guide chain 42, which can effectively reduce the impact on the drainage pipe wall and reduce the noise. At the same time, the water guide chain 42 guides the water flow, which can maintain unobstructed water flow and air flow paths in the drainage pipe, ensuring smooth discharge of water and improving the drainage rate.

[0020] The interception plate 3 and the grille bars on the cover plate 2 are staggered in space to form a grid to intercept debris. Debris not intercepted by the cover plate 2 will also be intercepted by the interception plate 3. The spatial staggered form prevents flaky impurities such as leaves from blocking the grille holes and affecting the discharge of water. The double-layer grille reduces the probability of blockage.

[0021] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
