Description

Technical Field

[0001] The utility model relates to the technical field of rainwater discharge, in particular to an adjustable split-flow municipal rainwater discharge system. Background Art

[0002] In the early stage of urban infrastructure construction, my country did not separate drainage pipes according to the source of water. Instead, it adopted the form of rainwater and sewage sharing one drainage pipe, that is, a combined drainage system. With the development of the economy and the enhancement of environmental awareness, coupled with the increasing preciousness of water resources, in order to better utilize various water resources, rainwater diversion discharge has begun to be implemented. Adjustable rainwater diversion discharge equipment is used in sponge city scenarios. Rainwater diversion refers to the various treatments of rainwater, including water absorption, water storage, water infiltration, and water purification when it rains. By adjusting the diversion drainage equipment in advance, the stored water can be released and utilized to achieve the free migration of rainwater in the city. The rainwater is discharged into the ground using the discharge equipment, and a part of it slowly infiltrates into the ground to replenish the groundwater source.

[0003] In the prior art, for example, Chinese patent CN218713692U discloses a rainwater diversion discharge device, including a box body, a manhole cover is provided on the box body, a filter screen is provided in the box body, a threaded rod is rotatably installed in the box body, a cleaning plate is threadedly connected to the threaded rod, a cleaning brush is provided at the bottom end of the cleaning plate, the bottom end of the cleaning brush is in contact with the filter screen, one end of the threaded rod passes through the box body and is connected to a first motor, a mounting groove is provided on the side wall of the box body, and a movable shaft passes through the side wall of the box body.

[0004] However, in the prior art, such as the above-mentioned patent, although the cleaning plate is driven to push the debris to both sides and fall into the collection groove, and the cleaning brush cleans the surface of the filter screen at the same time, there are still the following disadvantages. When rainwater flows, it will wash away various debris on the road, such as stones, branches, etc., causing various debris to flow into the diversion discharge device together with the rainwater, and then be filtered through the internal filter screen. Various debris will be stuck in the holes in the filter screen during the filtration. This makes it difficult for the cleaning brush in the above-mentioned patent to completely clean the filter screen. Over time, the filter screen will be blocked, making it impossible to continue filtering rainwater. Utility Model Content
