Technical Field
[0001] The utility model relates to the technical field of bridge drainage, in particular to a bridge drainage structure. Background Art
[0002] Bridges generally refer to structures built across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology, or meet other transportation needs to make passage more convenient; after the construction of the bridge is completed, in order to quickly drain the bridge deck and avoid water seepage inside the bridge, which affects the safety and durability of the bridge, it is necessary to construct a drainage structure on the bridge during the construction process to quickly drain the water layer on the bridge deck.
[0003] Please refer to a bridge drainage structure with announcement number CN112012100B. In the patent, it is proposed that "the traditional method adopts more than one drainage hole to be opened on both sides of the bridge deck road, but this method is difficult to achieve rapid drainage, the drainage efficiency is low, and the drainage hole is very easy to be blocked by fallen leaves or other dust, thereby losing the drainage function". The above embodiment drives the impeller to rotate through the flow of rainwater during drainage, and the impeller drives the second rotating shaft to rotate through the first belt. The second rotating shaft drives the piston to move through the crankshaft, and the piston generates gas to be ejected from the nozzle to blow away the fallen leaves or dust around the protective plate;

When the flow rate in the drain pipe is small, the rotation of the impeller cannot drive the piston to operate. If blockage occurs at this time, a good cleaning effect cannot be guaranteed. This application proposes another technical solution to solve this technical problem. Utility Model Content

[0027] In this embodiment, a second slit 301 is provided at the bottom of the fixing ring 3, a cover plate 2 which fits the fixing ring 3 is detachably connected to the top of the bridge body 1, a first slit 201 corresponding to the position of the second slit 301 is provided at the bottom of the cover plate 2, a cleaning component for cleaning the first slit 201 and the second slit 301 is provided on the inner side of the fixing ring 3, a flow sensor 502 is fixedly connected to the inside of the drain pipe 5, the flow sensor 502 is used to monitor the flow in the drain pipe 5, so that the cleaning component can operate automatically when the flow is reduced due to blockage.
[0028] Among them, the cleaning component includes a driving member 8 fixedly connected inside the water tank 6, the output end of the driving member 8 is fixedly connected to a rotating arm 9, the internal sliding connection of the rotating arm 9 is connected to a telescopic rod 11, the end of the telescopic rod 11 away from the rotating axis of the rotating arm 9 is fixedly connected to a push plate 10, and the end of the telescopic rod 11 away from the push plate 10 is fixedly connected to an extrusion spring 12, so that the push plate 10 can be extended outward under the push of the extrusion spring 12 without obstruction, so as to sweep across the first slit 201 and the second slit 301 for dredging.

[0035] The working principle of the above embodiment is:
[0036] In the bridge drainage structure, when the user is using it, the accumulated water on the bridge deck can flow to the water tank 101 through the first slit 201 and the second slit 301. The rainwater entering the water tank 101 can enter the water tank 6 through the water inlet 601 after passing through the filter plate 7, and flow to the drain pipe 5 to achieve drainage. In this process, the flow sensor 502 can monitor the flow in the drain pipe 5. When the flow sensor 502 can sense that the flow is reduced, it means that the first slit 201 and the second slit 301 are blocked by debris such as fallen leaves. At this time, the driving member 8 can be operated to make the rotating arm 9 drive the push plate 10 to rotate, so as to facilitate In cooperation with the pushing effect of the extrusion spring 12 on the telescopic rod 11, the push plate 10 extends outward, so that the push plate 10 sweeps back and forth in the first slit 201 and the second slit 301, pushing outward the fallen leaves and other debris that cause the blockage, thereby achieving the effect of dredging and maintaining the drainage effect; in addition, the filter plate 7 set can also intercept fine debris such as mud and sand carried by rainwater, and use the collection frame 14 to collect fine debris such as mud and sand, so as to facilitate opening the cover 2 for cleaning after the weather is clear, thereby effectively avoiding the situation where the drainage effect is weakened due to excessive deposited debris.
