Ultrasonic wave absorbed layer 211 can be the silica gel piece for being fitted in the inwall of water storage container 21, or be coated in the inwall of water storage container 21
Absorber coatings, the absorption process of ultrasonic wave known to those skilled in the art, the disclosure to its concrete form not
It is limited.
Influent hopper in present embodiment can include the first funnel 12 and the second funnel 13 of mounted on top, the first leakage
Bucket 12 is fixed on above-mentioned cylindrical shell 11, and gap can be left between the first funnel 12 and the second funnel 13, and rainwater is first
First pass through the first funnel 12 and pass through the second funnel 13 again.Wherein, the hopper walls of the first funnel 12 and the second funnel 13 can be distinguished
With vertical section and tilting section.Specifically, as shown in figure 1, the top of the first funnel 12 is fixed on shell 11, the first funnel 12
Vertical hopper walls are arranged at intervals with shell 11 so that the vertical hopper walls of the second funnel 13 are inserted into the first funnel 12
With the gap between shell 11.Due to the first funnel 12 and shell 11 form as one can be as udometric top cover, this
Sample, when rainwater is fallen can completely into the second funnel 13, without flow into the second funnel 13 with the gap of shell 11,
Cause the grade parts damages of control system 70, also make it that measurement effect is more accurate.
The top of shell 11 can be provided with cover plate 16, and rainfall gauge can cover cover plate 16 in shell under non-working condition
11 tops, to prevent impurity from entering, when needing to use rainfall gauge, cover plate 16 is removed, easy to operate.
Further, filter is provided with the first funnel 12, to avoid impurity from entering rainfall gauge.Filter can be with
Including following screen clothes 14, filter 15 etc..Specifically, inwall of being fitted in the first funnel 12 is generally horizontally provided with screen cloth
14, so as to avoid the impurity such as leaf from blocking water inlet pipe 24, and then influence to insert at measurement accuracy, the sharp-crested of the first funnel 12
Enter to have filter 15, it is to avoid impurity enters in water inlet pipe 24, filter 15 can be the screen pack of hollow cylindrical, the He of screen cloth 14
Filter 15 can be used cooperatively, and realize secondary filtration, and measurement data is relatively reliable.
In addition, influent hopper is divided into double-layer structure can facilitate udometric dismounting, be conducive to overhaul of the equipments, specifically
