Embodiment Construction

[0025] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] Such as Figures 1 to 4 As shown, an automatic urban rainfall runoff sampler is composed of a box body 27 , a water collection structure, a sampling room 1 and an instrument control room 20 .

[0027] Described casing 27 is cuboid, and its size can be placed in the rectangular sewer well of roadside in most cities. The upper part of the box body is an openable box cover 28, which is fixed to the lower part of the box body by buckles 25 for placing and taking out the sampling cup 8. The four jiaos of case cover have hook 29, and sampler can be hung on the grid well cover of sewer well.

[0028] The water collection structure includes a detachable water collection funnel 2 arranged outside the box body and its automatic opening / closing device; There is a water inlet, which is connected with a water diversion pipe 5 and enters the sampl...

Abstract

The invention relates to an automatic urban rainfall runoff sampler characterized by comprising a tank body, a catchment structure, a sampling chamber and an instrument control room, wherein the tank body is cuboid; an openable upper cover constitutes the upper part of the tank body and is fixed with the lower part of the tank body via fasteners; hooks are arranged at four corners of the upper cover of the tank body; the catchment structure comprises a detachable catchment hopper arranged outside the tank body and an automatic opening/closing device thereof; the sampling chamber consists of a water guiding pipe, a water inlet pipe, a rotating shaft, a sampling base, a sampling ring and a water discharging pipe; the instrument control room is located on the right side of the tank body and separated from the sampling chamber; a rainwater sensor, a stepping motor and a storage battery are placed inside the instrument control room; and the instrument control room is further provided with an openable door, so as to facilitate the device maintenance and repair. The automatic urban rainfall runoff sampler of the invention has the characteristics of high automation level, compact structure, small size, high portability and convenient management. Therefore, the invention is applicable to the collection of rainfall runoff in the urban wayside sewers and other places for the collection of rainfall runoff or water flow.

Description

【Technical field】 [0001] The invention relates to an automatic urban rainfall runoff sampler, in particular to an automatic sampler for collecting urban road surface rainfall runoff in different periods for urban non-point source pollution analysis. The sampler can be applied to environmental monitoring and hydrometeorological departments to collect rainfall runoff. 【Background technique】 [0002] According to the different characteristics of pollution sources, water pollution can be divided into point source pollution and non-point source pollution. Urban non-point source pollution refers to the pollution of receiving water bodies caused by urban rainfall runoff leaching and scouring the atmosphere and various pollutants on catchment surfaces. Among them, rainfall is the driving factor for the formation of urban non-point source pollution, and the runoff formed by rainfall is the carrier of the migration of non-point source pollutants. Therefore, urban non-point source pol...
