Description
Technical field
The utility model is related to a kind of rain water drainage collection devices, and variable flow initial rainwater is abandoned more particularly, to one kind
Flow abandoning apparatus.
Background technology
Early-stage rainwater stream abandoning device is mainly used in Rainwater collection system.When initial rainwater refers to rainfall initial stage
Rainwater.During collecting rainwater in the collection such as roof, ground, slope surface rain face, at rainfall initial stage, due to rainwash and molten
Solution so that it is higher that initial rainwater contains polluters, the pollution levels such as birds droppings, leaf, the dust retained on collection rain face.
If initial rainwater enters rain collecting pool, the water quality of rainwater collected in rain collecting pool can be influenced, is threatened using rainwater as drinking water
The safe drinking water of the water-deficient area resident in source.It is found by investigation, the poor initial rainwater water of Rainwater Quality continues with arid
There is close relationship in time, when it is long-term there is no rainfall when, i.e., when arid duration is longer, the pollutant of rainwater carrying compared with
It is more so that the water of initial rainwater is larger, collects the water quality safety of rainwater for guarantee at this time and should then increase corresponding abandoned stream amount；And
When rainfall frequency higher period, i.e., when the arid duration is shorter, the pollutant that rainwater carries is less so that the water of initial rainwater
Amount is smaller, should reduce corresponding abandoned stream amount at this time to reduce the waste of rainwater resource.
Existing early-stage rainwater stream abandoning device can not regulate and control rain water drainage according to the water quality of rainfall, the frequency of rainfall mostly
Amount, so in rainfall frequency high rainy season, Rainwater Quality is preferable, but due to can not be according to the water quality of rainfall, the frequency tune of rainfall
Control rain water drainage amount so that abandoned stream amount is larger, causes the waste situation of rainwater resource.Also there is part early-stage rainwater stream abandoning device
Using variable flow early-stage rainwater stream abandoning device is abandoned, although it can adjust abandoned stream according to the water quality of rainfall and the frequency of rainfall
Amount, but existing variable flow early-stage rainwater stream abandoning device is abandoned in order to realize mesh that abandoned stream amount is adjusted according to rainfall frequency
, all controlled using electrified, including equipment such as water quality sensor, water quality testing meter and servomotors, but these equipment
Cost is high, it is expensive to safeguard, very heavy financial burden is caused to the resident of water deficient regions, it is affected and promotes the use of；Further, since water
The equipment such as matter sensor, water quality testing meter and servomotor are required to electric energy to drive, and early-stage rainwater stream abandoning device is often sudden and violent
Outdoor is exposed at, long-term being exposed to the sun, which drenches with rain, to be easy to cause the failure of early-stage rainwater stream abandoning device or even leaky occurs, and is affected
Its adaptability used, reliability and security.
Utility model content
The purpose of this utility model is just to provide one kind and abandons variable flow early-stage rainwater stream abandoning device, existing to solve
It abandons present in variable flow early-stage rainwater stream abandoning device due to the use of water quality sensor, water quality testing meter and servomotor
Etc. the problem of it is with of high cost, bad adaptability, poor poor reliability and security caused by equipment.
What the purpose of this utility model was realized in：
One kind abandons variable flow early-stage rainwater stream abandoning device, including rainwater collection collector, abandoned stream amount control device and abandoned stream
