Technical Field
[0001] This utility model relates to the field of sponge city technology, and in particular to a road drainage device for preventing blockages in sponge cities. Background Technology
[0002] Sponge city is a new generation of urban stormwater management concept. It refers to a city that can be as resilient as a sponge in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called a "water-resilient city". The internationally used term is "low impact development stormwater system construction". When it rains, it absorbs, stores, infiltrates, and purifies water. When needed, it releases and utilizes the stored water, realizing the free migration of rainwater in the city.
[0003] In the process of constructing sponge city roads, drainage devices are particularly important. Currently, drainage devices are generally drainage ditches on both sides of the road. During the drainage process, the water in these ditches may contain some large pieces of garbage. If this garbage enters the drainage device, it can easily cause blockages and affect the normal operation of the drainage work.

[0030] As an optional technical solution of this utility model, the cross-sectional shape of the flow guide shell 12 is an isosceles trapezoid. The flow guide shell 12 is located below the filter screen 3, so that the water filtered by the filter screen 3 can enter the interior of the flow guide shell 12.
[0031] As an optional technical solution of this utility model, the cross-sectional shape of the sealing seat 20 is an isosceles trapezoid, the sealing block 20 corresponds to the position of the drainage shell 13, and the size of the sealing block 20 is larger than the size of the drainage shell 13, so that the sealing block 20 can seal the drainage shell 13.
[0032] As an optional technical solution of this utility model, the baffle 22 is attached to one side of the inside of the drainage ditch 1, the baffle 22 is slidably connected to the drainage ditch 1, and the size of the baffle 22 is larger than the size of the drainage trough 11, so that the baffle 22 can move smoothly and seal the drainage trough 11.
[0033] A road drainage device for preventing blockages in sponge cities works on the following principle:
[0034] When garbage enters the interior of the drainage ditch 1, the filter screen 3 will block and filter the garbage.
