Problems solved by technology

However, the area of ​​the rainwater outlet is small, it is difficult to install with advanced collection and monitoring equipment, and there are problems such as difficult management
However, it is not accurate to collect directly from the road surface, so it is very important for the research and development of on-site runoff collectors
[0003] The patented technology for rainfall and runof

Example Embodiment

[0022] Example 1: Such as figure 1 , 2 , 3 shows,

[0023] Rainfall runoff collector, including funnel body 2 and collecting bucket 6. The funnel body 2 has a funnel upper edge 1 that is attached to the rainwater outlet; the collection bucket 6 has a collection bucket upper edge 5 that is attached to the funnel lower edge 3 on the funnel body 2, and the collection bucket lever 4 is convenient for the lifting and lay down. The funnel body 2 collects surface rainfall runoff, and the collection bucket 6 is used to block, collect and divert the runoff. The runoff collecting funnel body 2 has a shape of a vertebral body with a large upper portion and a smaller lower portion, which aims to collect surface runoff, and its material is a PVC board. The collecting funnel body 2 has a funnel upper edge 1, and its width is greater than 1 cm, and the purpose is to make it lean on the frame around the gully. Before the runoff is collected, apply glass glue to the gap between the rainwater ...

Example Embodiment

[0024] Embodiment 2: A pressure sensor is installed at the bottom of the runoff collecting barrel 6 to measure continuous flow changes.

Abstract

The invention belongs to the technical field of environment friendliness and in particular relates to a rainfall runoff collector. The rainfall runoff collector comprises a funnel body 2 and a collection barrel 6, wherein the funnel body 2 has an upper edge 1 which is fit to a rainwater outlet; the collection barrel 6 has an upper edge 5 which is fit to a lower edge 3 of the funnel body 2; and the collection barrel 6 is conveniently lifted and put down by virtue of a lifting rod 4. The surface rainfall runoff is collected by virtue of the funnel body 2, and the collection barrel 6 is used for blocking and dredging the runoff. Compared with the conventional device, the rainfall runoff collector disclosed by the invention can simultaneously collect the runoff and measure the instantaneous flow of the runoff and has the advantages of convenience, simplicity, rapidness and the like.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a rainfall runoff collector. Background technique [0002] At present, most of the large and medium-sized cities in China are hardened to form an impermeable underlying surface. When it rains, the runoff formed on the surface cannot be infiltrated underground, and most of it is discharged by pipelines. However, the design standards of rainwater drainage pipes in our country are relatively low, and extreme weather phenomena have occurred frequently in recent years. Therefore, many urban waterlogging problems have emerged. For this reason, the study of rainfall runoff on the underlying surface is of great significance for solving the problem of urban waterlogging. At the same time, the erosion of pollutants on the underlying surface by rainfall runoff has also become an important non-point source pollution of rivers. Therefore, the study of rainfall r...
