Embodiment 1

[0023] This embodiment is a monitoring system for the relationship between runoff and rainfall on the underlying surface, such as figure 1 mentioned. This embodiment includes: a runoff monitoring unit 1 and a rainfall monitoring unit 2. The runoff monitoring unit is provided with a water-insulating fence 102 surrounding a part of the surface 101 of the underlying surface to be measured. The water-insulating fence and the The water-stopping material 103 is used to seal between the underlaying surfaces, and the runoff collecting device 104 is provided on one side of the fence, and the runoff collecting device is connected with the runoff flow meter 105; the rainfall monitoring unit is provided with The sump 201 that is completely consistent with the horizontal projected area of ​​the water-insulating fence, the sump is provided with a rain collector 202, and the rain collector is connected to the rain gauge 203, and the production flow meter and the rain gauge The water meter ...

Embodiment 2

[0034] This embodiment is an improvement of the first embodiment, and is a refinement of the first embodiment on the production flow collection device. The runoff collection device described in this embodiment is installed on the funnel on one side of the water-insulating fence.

[0035] The funnel described in this embodiment is a sideways funnel, forming a water collector 1041 from the flared mouth to the narrowed mouth, and entering the water guide pipe 1042, and the water guide pipe sends water into the water measuring device, such as figure 2 shown.

Embodiment 3

[0037] This embodiment is an improvement of the above embodiment, and is a refinement of the above embodiment about the rain collector. The rain collector described in the present embodiment is sump 2021 and water pump 2022, as image 3 shown.

[0038] In this embodiment, a sump pit is set in the sump, so that the rainwater in the sump is concentrated in the flow path of the sump, and then the rainwater in the sump is pumped out by a water pump, and transported to the rainfall meter. The water collection effect of the sump is very critical, which determines whether the water pump can work normally. It must be able to collect the rainwater in the sump as much as possible. Generally, it can be in the shape of a funnel with a closed bottom. The bottom of the funnel is flat, and the suction pipe inlet of the water pump is set. .

[0039] The water pump can be equipped with a water level sensor to detect the amount of water in the puddle to realize the function of automatically t...

Abstract

The invention relates to a monitoring system and method for a relation of runoff and rainfall of an underlying surface. The monitoring system comprises a runoff monitoring unit and a rainfall monitoring unit, wherein the runoff monitoring unit is provided with a water insulation fence enclosing a partial surface of the to-be-monitored underlying surface; a gap between the water insulation fence and the to-be-monitored underlying surface is sealed by a sealing material; a runoff collection device is arranged on one side of the water insulation fence, and connected with a runoff water measurement meter; the rainfall monitoring unit is provided with a water collection tank which is identical to a horizontal projected area of the water insulation fence; the water collection tank is provided with a rainfall collector; the rainfall collector is connected with a rainfall water measurement meter; the runoff water measurement meter and the rainfall water measurement meter are connected with a data processing device by a data acquisition device. According to the system and the method, the rainfall capacity and the runoff capacity are measured by a prototype experiment; prototype determination by calculating rainfall and runoff coefficients of the underlying surface is realized; a corresponding relation of the runoff capacity and the rainfall capacity is realized by synchronously monitoring the rainfall capacity; a corresponding relation of the rainfall and runoff capacity and a runoff area is fully considered.

Description

technical field [0001] The invention relates to a monitoring system and method for the relationship between runoff and rainfall on an underlying surface, is a hydrological monitoring system and a method, and is suitable for monitoring the rainfall and runoff on an underlying surface in the field of water circulation. Background technique [0002] Rainfall runoff is a key link in the hydrological cycle process, and it is also the core task of river basin and urban runoff and flood forecasting. Especially in urban areas, the underlying surface is very complex, mainly hardened ground or hardened roof, and the original infiltration monitoring equipment cannot be applied. In recent years, under the dual effects of urbanization and climate change, urban flood disasters have occurred frequently. In order to alleviate urban waterlogging disasters, my country has started the construction of sponge city pilot cities nationwide since 2015. The annual total flow control rate is a rigid...
