Abstract
The invention relates to an automatic cap-rotating type fresh rain flow discarding device which is used for automatically controlling the discharging of the fresh rain by rainfall in the rainwater collecting process. Long-term lack of rainfall can lead the rainwater to eluviate a great amount of atmospheric pollutants, in addition, runoff rinses the dust and soluble and insoluble sundries of an open-air rain-bearing face, and the rainwater of the part is called as the fresh rain. The degree of contamination of the fresh rain is higher, therefore, timely treatment is needed to be carried out in the rainwater collecting process. The device measures and calculates the fresh rainfall by a flow dividing tank and changes device balance by utilizing gravity, therefore, only clean rainwater is collected and other fresh rain is automatically discharged. Therefore, not only a plurality of shortcomings of the traditional devices are made up, but also the aim of discharging the fresh rain is achieved.
Description
Technical field
The invention belongs to automatic initial rainwater discharge device.Be applicable in the process of rainwater catchment system.
Background technology
Along with the gradually attention of people to rainwater catchment system, the rainwater collecting amount also increases thereupon.Owing to do not have a rainfall for a long time, rainwater drip washing a lot of atmosphere pollutions, and runoff has tangible initial stage souring, the dust and the soluble and insoluble foreign material that are subjected to the rain face have in the open been washed, this part rainwater is called as rain just, and its pollution threat can not be out in the cold again, should be discharged.Because pollutant only concentrates in the several millimeters rainfall at initial stage, therefore, control early-stage rainwater (promptly first rain) becomes a requisite behave of rainwater utilization system.In the face of this situation, the initial rainwater discharge device has just arisen at the historic moment.
Traditional initial rainwater discharge equipment has a variety of, but all has not enough place.
1, construction space is bigger.A lot of equipment are that all first rain is collected, and the first rain that will collect carries out rainwater and collects as power set after rain collection is just finished.For the bigger place of area, the flow of first rain is very considerable, and it is all collected needs very big space, also needs great amount of manpower and material resources.
2, need electric power or other power.Some initial rainwater discharge devices are to utilize electronic grout flow meter or other similar devices to detect the flow of rainwater, calculate rainfall just according to planimeter, and with its discharging.Owing to used electric power or other power-equipments, very trouble just seems in the place that lacks power resources.
3, complex manufacturing technology.
Summary of the invention
The present invention has overcome the deficiency of traditional initial rainwater discharge device, not only saves space, simple for production but also need not power, also collects rain just unlike other equipment, but directly with its discharging, can protect the ecological environment of this area so to a certain extent.Its signal is shown in figure one.Below the structure of apparatus of the present invention is done detailed description.
What fixed axis was selected for use is that long 6～10 cm diameters are 3～8 millimeters smooth stainless steel shaft.The fixed axis on the pipe top baffle plate that is used for fixing, overturns.The fixed axis of pipe side is in order to keep the position of inactive state lower baffle plate.The installation of fixed axis then is to use two-layer wide about 8～10 centimetres semicanal body and function adhesive specially to fix.Baffle plate is that 3～4 millimeters plastic plate constitutes by thickness, and size is decided by the header bore.Be shaped as circular upper part and square lower part, outstanding longer 6～8 centimetres, wide 4～6 centimetres rectangle plate body in the top is used for fixing weight and dust-collecting bucket.Splitter box is to use the ABS resin plate, utilizes plastic adhesive tape and adhesive specially to be made.Its length is identical with baffle plate, width and highly be 2～3 centimetres.Bottom land is provided with several holes, and its quantity and size are that the amount by first rain decides.One of them hole is connected with intake pipe (diameter of intake pipe is by the size decision of hole), and first rain is introduced dust-collecting bucket by the hole that bores in advance on the good dust-collecting bucket bung.Other holes then directly discharge first rain.The capacity of dust-collecting bucket is determined that by first rainfall its capacity is as far as possible little in principle, is upgraded to good with 2～10.Weight of heavy only needs to get final product than the maximum weight of dust-collecting bucket is smaller.
Apparatus of the present invention are mounted in the dirty pipe bent position of rainwater in principle, bend pipe is done certain inclination can achieve the goal, shown in figure two.When rain flows out by header originally, because the existence of baffle plate, rainwater will flow into splitter box by baffle plate, flow into dust-collecting bucket through intake pipe again.When the weight of dust-collecting bucket greater than weight the time, baffle plate will be along the fixed axis rotation on pipe top, thereby opens the mouth of pipe, makes rainwater enter body, has so just reached the purpose of the first rain of discharging.
Through practice, apparatus of the present invention can well be finished the discharging task of rain just, and the cost cost is very cheap.

Claims (3)
1, a kind of initial rainwater discharge equipment is made up of fixed axis, baffle plate, splitter box, weight, intake pipe, dust-collecting bucket, header etc.
It is characterized in that: this novel initial rainwater discharge equipment is to rely on to change the purpose that the self gravitation balance need not exterior power and reaches the first rain of discharging.Wherein splitter box can science practicably plays the effect of shunting.
2, initial rainwater discharge equipment according to claim 1, it is characterized in that having splitter box, dust-collecting bucket and header, its splitter box can change the wherein size and the number of spillway hole according to the different regions annual precipitation and the different science in rainfall season, and science plays the purpose and the requirement of shunting.
3, initial rainwater discharge equipment according to claim 1 is characterized in that the small and exquisite practicality of dust-collecting bucket, effectively plays according to changing the requirement that own wt is outwarded winding baffle plate.
