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...

Examples

Embodiment 1

[0022] Embodiment 1: as figure 1 , 2 , as shown in 3,

[0023] The rainfall runoff collector includes a funnel body 2 and a collection bucket 6. The funnel body 2 has a funnel upper edge 1 that fits with the rainwater outlet; the collection bucket 6 has a collection bucket upper edge 5 that fits with the funnel lower edge 3 on the funnel body 2, and the collection bucket handle 4 is convenient for the lifting of the collection bucket 6 and lay down. The surface rainfall runoff is collected through the funnel body 2, and the collection bucket 6 is used for blocking, collecting and channeling the runoff. The runoff collection funnel body 2 is in the form of a cone with a large upper part and a smaller lower part. The purpose is to collect surface runoff, and its material is a PVC board. Collecting funnel body 2 has a funnel upper edge 1, and its width is greater than 1cm, and purpose is to make it lean against on the frame around rainwater outlet. Before the runoff is coll...

Embodiment 2

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