Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road drainage, in particular to an environmentally friendly road drainage mechanism. Background Art
[0002] Urban roads are roads that connect various areas of the city and are used for transportation and pedestrians within the city. They are convenient for residents' lives, work, cultural and entertainment activities, and are connected to roads outside the city to carry external traffic. In order to enable rainwater to be quickly discharged from the road surface when it rains, drainage pipes are usually installed on the road. In order to filter large floating objects such as leaves, filter covers are usually installed above the drainage pipes to avoid clogging of the drainage pipes by floating objects. However, rainwater on the ground will carry a large amount of mud and sand before flowing into the drainage pipes. In order to ensure the normal operation of the drainage system, the filter holes on the filter covers are usually large and cannot filter the mud and sand in the rainwater. If rainwater carries mud and sand into the drainage pipes for a long time, it will accumulate in the drainage pipes, causing clogging of the drainage pipes and affecting road drainage.

An overflow filter screen is arranged on the top of the overflow tube 10, and the connecting hole, the height of the connecting hole is lower than the upper edge of the sand settling ring weir 5. A sand discharge hole is opened at the bottom of the side wall of the sedimentation tube 4, and a sand discharge mechanism is connected to the outer side of the sand discharge hole, and the sand discharge mechanism includes a discharge Sand ring 6, lifting motor 7, lifting screw 8 and sand discharge bucket 9, the sand discharge ring 6 is slidingly matched with the outer wall of the deposition tube 4, the cover is set on the outside of the sand discharge hole, the lifting motor 7 is fixed on the outer wall of the deposition tube 4, the lifting screw 8 is connected to the sand discharge ring 6 and the lifting motor 7, the sand discharge ring 6 is provided with a lifting nut, the lifting screw 8 is threadedly matched with the lifting nut, the sand discharge bucket 9 is covered on the outside of the deposition tube 4, and the sand discharge bucket 9 includes an integrally formed cover portion 91, a sliding portion 92 and a water seepage portion 93, the cover portion 91 is fixed on the inner wall of the drainage tube body 1, the upper edge of the cover portion 91 is arranged higher than the sand discharge hole, the sliding portion 92 is arranged in an inclined arc shape, a plurality of water seepage holes are arranged on the water seepage portion 93, the water seepage portion 93 is sleeved on the outside of the drainage pipe 2, a water seepage cavity is formed between the water seepage portion 93 and the drainage pipe 2, a plurality of reflux holes are opened on the side wall of the drainage pipe 2 corresponding to the position of the water seepage cavity, and the water seepage holes and the reflux holes are connected with the water seepage cavity.
[0024] Furthermore, the cross section of the sand settling ring weir 5 can also be set to be a corrugated ring.
[0025] Working principle: rainwater carrying silt and floating objects passes through the water inlet hole to filter out large floating objects such as leaves and garbage, and enters the spiral waterway 3 with silt and small floating objects. The spiral waterway 3 can reduce the flow rate of rainwater, so that the initial flow rate of rainwater entering the sedimentation chamber is reduced, so as to increase the sedimentation effect of silt. The rainwater will slowly rise in the sedimentation chamber until the liquid level is higher than the sand settling ring weir 5. The rainwater above the sand settling ring weir 5 will overflow from the sand settling ring weir 5 to the outside of the drainage pipe 2 until the rainwater liquid level is higher than the height of the drainage pipe 2. As the liquid level rises, the rainwater overflows into the drainage pipe 2 for discharge. The rainwater liquid level is higher than the height of the drainage pipe 2, that is, higher than the height of the connecting hole, so that small floating objects can only float on the outside of the overflow tube 10, and the rainwater enters the drainage pipe 2 from the connecting tube hole. At the same time, the cross-section of the sand ring weir 5 can also be set to a sawtooth ring, which increases the overflow area, can reduce the flow rate of the overflow rainwater, reduce disturbance, and further increase the sedimentation effect of silt.
[0026] When a certain amount of silt is deposited, the sand discharge ring 6 is lifted by the lifting motor 7 to connect the sand discharge hole with the sand discharge bucket 9, and the deposited silt is impacted into the sand discharge bucket 9 by the water flow, and the rainwater and silt slide from the sliding part 92 of the sand discharge bucket 9 to the bottom, and under the action of the water seepage part 93, the rainwater and silt are further separated, and the rainwater is returned to the drainage pipe 2, completing the separation of silt and rainwater.
