Description
Technical field
The utility model is related to a kind of underlying surface rainfall runoff automatic sampling apparatus, belongs to data water conservancy and environmental area.
Background technology
In recent years, Roof Runoff Pollution Study is at home and abroad attracted wide attention.On the one hand, in the city that heavy rain triggers
Flood is increasingly frequent, on the other hand, and the city surface source pollution using urban storm runoff as carrier has turned into the master that urban water-body pollutes
One of originate.In order to study the Runoff characteristic of different periods in the different underlying surface runoff process such as roofing, it is necessary to automatic
The device of underlying surface runoff water sample is gathered at times.At present sampler on the market can only substantially gather larger flow current or
Larger volume water body water sample, it is difficult to obtain the Part I water sample of the runoff in small areas rainfall-runoff process.Therefore it is urgent
Exploitation one kind is needed to complete to sample automatically at times, and cost is low, safeguard less, the high sampling apparatus of applicability.
Utility model content
For the above mentioned problem of prior art, the utility model provides a kind of automatic data collection roofing, road surface, grass at times
The automatic sampling apparatus of the underlying surface runoff water sample such as ground, forest land.
To achieve the above object, the utility model includes following technical scheme：
A kind of underlying surface rainfall runoff automatic sampling apparatus, it includes outer barrel 1, interior cup 2, floating-ball level switch 3, sluicing electricity
Dynamic valve 4, controller 7, water pump 8 and sampling bottle 9；
The top of outer barrel 1 has upper interface 101, and bottom has lower interface 102；
Interior cup 2 is fixed on inside outer barrel 1, the lower section of interface 101 in outer barrel 1；Floating-ball level switch 3 is set on the interior wall of cup of cup 2,
Interior cup is connected by sampling pipe 5 with water pump 8, and interior cup bottom sets sluicing motor-driven valve 4；
The water inlet connection sampling pipe 5 of water pump 8, delivery port connection sampling bottle 9；
Floating-ball level switch 3, sluicing motor-driven valve 4 and water pump 8 are connected by wire with controller 7 respectively.
Underlying surface rainfall runoff automatic sampling apparatus as described above, it is preferable that the described height of outer barrel 1 is 50~
80cm, internal diameter is 25~40cm；The described height of interior cup 2 is 20~30cm, and internal diameter is 10~20cm.
The beneficial effects of the utility model are：Device sluicing motor-driven valve when not raining is closed mode, during rainfall
Runoff enters sampling apparatus, and water sample is gathered into sampling bottle according to setting program, and opening sluices after completing once to sample
Rainwater in motor-driven valve emptying in cup, is then again switched off valve to treat to sample next time in the time of setting.The device is solved
Common sampler can only gather larger flow current or larger volume water body water sample, can not gather large change flow weep
The difficult point of water sample, when the water quality that can ensure the water sample of extraction substantially by the setting of motor-driven valve and floating-ball level switch is setting
Between the water quality that needs.And cost is few, safeguards less, be easily portable, and can preferably serve to the different underlying surface runoff water such as roofing
The scientific research of matter, so as to more fully recognize the polluting property of precipitation runoff.
Brief description of the drawings
Fig. 1 is a kind of preferred embodiment underlying surface rainfall runoff automatic sampling apparatus structural representation of the utility model.
Fig. 2 is a kind of preferred embodiment underlying surface rainfall runoff automatic sampling apparatus top view of the utility model.
Embodiment
Embodiment 1
As shown in Fig. 1~Fig. 2, in a kind of preferred embodiment of the present utility model, the underlying surface rainfall runoff is automatic
Sampling apparatus includes outer barrel 1, interior cup 2, floating-ball level switch 3, sluicing motor-driven valve 4, controller 7, water pump 8 and sampling bottle 9.
The top of outer barrel 1 has upper interface 101, and bottom has lower interface 102.The diameter and rainwater down pipe of upper interface and lower interface
Diametric fit, can be to access rainwater down pipe.The height of outer barrel 1 is 50~80cm, and internal diameter is 25~40cm.
Interior cup 2 is fixed on inside outer barrel 1, collects the rainwater flowed down for receiving the interface 101 from outer barrel.Interior cup is a height of
20cm, volume is 3760ml, and material is stainless steel.Floating-ball level switch 3 is set on the interior side wall of cup 2.Interior cup bottom, which is set, to sluice
Motor-driven valve 4.Interior cup is connected by sampling pipe 5 with water pump 8.The delivery port connection sampling bottle 9 of water pump 8.
Floating-ball level switch 3, sluicing motor-driven valve 4 and water pump 8 are connected by wire with controller 7 respectively.
The process of device collection rainwater is as follows：Rainfall is imported in the interior cup 2 in automatic water sample collection terminal by rainwater down pipe,
Now sluicing motor-driven valve 4 is closed, when water level reaches the position of ball float, when being set to water in the present embodiment and reaching 1500ml,
Floating-ball level switch 3 is signaled to sampling apparatus console controller 7, and main frame is opened water pump 8 according to default program and sampled, adopts
Sluicing motor-driven valve 4 is opened after the completion of sample, and the signal that valve 4 is opened is sent to sampling apparatus host computer control by call wire 6
Device 7 is recorded, and the rainwater in interior cup is discharged, and the collection water sample of valve 4 is again switched off until next setting moment arrives.
According to the speed of roof area and charge for remittance speed, reach that the time of ball float position differs.The present embodiment is according to room
Top area is calculated, it is ensured that the roof runoff that the rainfall that rainfall intensity is more than 3mm/5min is produced can reach float-level in 5min
Put, sampling apparatus is adopted the Part I water sample of runoff in rainfall-runoff process.When rainfall intensity is very big, more than 1500ml
Current can overflow the interior flow ipe from outer barrel of cup 2 and flow away, it is ensured that water sampling end is not sent out under larger rain fall
It is raw to hinder current phenomenon.
Embodiment of above is merely to illustrate the utility model, and is not limitation of the utility model, relevant technology neck
The those of ordinary skill in domain, in the case where not departing from spirit and scope of the present utility model, can also make a variety of changes and
Modification, therefore all equivalent technical schemes fall within category of the present utility model, scope of patent protection of the present utility model should
It is defined by the claims.
