Technical field
The present invention relates to waterworks or technical field of water purification, and in particular to a kind of collection measurement of rainfall runoff flow
Device.
Background technique
Rainwater is the water resource that a kind of water is considerable, low-cost, and it is slow for carrying out river channel ecology moisturizing using rainfall runoff
One of China's city river water shortage effective way is solved, but initial rainwater runoff carries a large amount of pollutants and is discharged into river by city planting ductwork
Road can cause river pollution, constitute a threat to water environment safety.
With the development of Urban Water Environment rectification engineering, early-stage rainwater stream abandoning device is by the serious portion of initial rainwater runoff pollution
Divide rainwater-collecting and send to sewage treatment plant and handled, reduce the water pollution risk of storage rainwater, and screens initial stage rain
The determination of water abandoned stream ratio needs to analyze the Regular of Water Quality Variation and feature of the rainfall runoff of different land use type, and mesh
Sample mode used in preceding is directly collected at municipal rain perforaled strainer grid using traditional sampling bottle, not only causes to miss
It is poor big, and be difficult to be collected into enough rainwater, it is even more impossible to carry out calculating rainfall runoff flow.
Summary of the invention
The object of the present invention is to provide a kind of collection measuring devices of rainfall runoff flow, are suitable for different municipal rainwater grids
Rainfall runoff acquisition and its flow measurement at grid realize that temporally ratio is acquired and calculates stream for rainfall runoff sampling
Amount.

Specific embodiment
The present invention will be described in detail With reference to embodiment.
The present invention relates to a kind of collection measuring devices of rainfall runoff flow, water storage box 6 including funnel 2 and below,
2 outlet at bottom of funnel accesses 6 top entry of water storage box, laterally connects L-type pipe 5 on path.2 outlet at bottom of funnel, water storage box 6 push up
Portion's entrance is connected with 5 entrance of L-type pipe by threeway.6 entrance of water storage box is provided with water storage box motor-driven valve 13, the setting of 5 entrance of L-type pipe
There is L-type pipe motor-driven valve 4.Vertical link-type floating-ball level switch 7 is provided in water storage box 6, link-type floating-ball level switch 7 connects
Connect and control water storage box motor-driven valve 13 and L-type pipe motor-driven valve 4.
Identical position is arranged two with the straight-bar bottom and top of link-type floating-ball level switch 7 height in water storage box 6
Liquid level sensor 8, two liquid level sensors 8 are respectively connected with sound or signal lamp prompt equipment.
Sampling bottle 11 is accessed by downpipe 10 in 6 bottom of water storage box, is provided with hand-operated valve 9, sampling bottle 11 on downpipe 10
It is placed on waterproof electronic scale 12.The rainwater that downpipe 10 will be collected under 9 full-gear of hand-operated valve in the short time in water storage box 6
Quickly export.
Filter cloth 3 is provided on funnel 2, so that the sundries such as rainfall runoff sand grains, rubbish are separated with rainwater.
The upper and lower frame of bracket 1 is welded by telescopic rod, changes the frame of bracket by stretching or compressing pull rod
Size.Bracket 1 is the outer rim of the device, and funnel 2 is mounted on the upper side frame of bracket 1, and waterproof electronic scale 12 is mounted on bracket 1
Lower frame, successively installs L-type pipe 5 and water storage box 6 under funnel 2, and sampling bottle 11 is placed on waterproof electronic scale 12.
Funnel 2 is made of folding waterproof cloth, changes funnel openings size by folding or being unfolded waterproof cloth, under
End is fixed by rigid plastics ring and is connected with L-type pipe 5, water storage box 6.
Size of the invention and the actual size of municipal rain perforaled strainer grid match, and open municipal rain perforaled strainer grid,
Bracket 1 is mounted at municipal rain perforaled strainer bayonet, each component is sequentially arranged on bracket.When device starts water receiving,
Close hand-operated valve 9, the floating ball of 6 inner link formula floating-ball level switch 7 of reservoir gradually rises up to L-type pipe during top by bottom end
Motor-driven valve 4 is closed, and water storage box motor-driven valve 13 is opened, and when floating ball reaches the top, L-type pipe motor-driven valve 4 is opened, water storage box motor-driven valve
13 close, and extra rainwater enters L-type pipe 5 and is discharged into catch-basin.The hand-operated valve 9 is opened, is collected in water storage box 6 with sampling bottle 11
Rainwater, when the floating ball of link-type floating-ball level switch 7 is down to connecting rod bottom, L-type pipe motor-driven valve 4 is closed, and water storage box is electronic
Valve 13 is opened.According to the prompt messages of liquid level sensor 8, the time of timer and the volume or waterproof of water storage box 6 are utilized
The gross mass of the weighed sample of electronic scale can precisely calculate the flow of rainfall runoff each time.
Liquid level sensor 8 in water storage box 6 is respectively in the identical height in straight-bar bottom and top of link-type floating-ball level switch 7
Degree setting liquid level sensor 8, bottom can connection signal lamp, top can connect music tip, record in time when signal lamp lights
The time started is sampled, the timely record end time when music tip signal sounds records waterproof after signal lamp is turned off the light in time
Data that electronic scale is shown simultaneously remove water sampling.
It is acquired according to time scale, if do not collect full water storage box 6 within the defined time, opens hand-operated valve in time
9 carry out the rainwater of packing water storage box and record weight, utilize recorded weight that the flow of sampling is roughly calculated.
Sampling is acquired according to time scale, if collect full water storage box 6 within the defined time,
New technical method is collected the invention proposes a kind of rainfall runoff, that is, changes the size of bracket and funnel to adapt to difference
The rain perforaled strainer of size, the rainfall runoff for completing different zones collect target;The new principle of rainfall runoff flow measuring is proposed,
Volume and the time of rainwater-collecting are recorded by floating-ball level switch and liquid level sensor, and then calculate run-off.
