Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
In figure, 1- bracket, 2- funnel, 3- filter cloth, 4- L-type pipe motor-driven valve, 5-L type pipe, 6- water storage box, 7- link-type is floating Ball liquid-level switch, 8- liquid level sensor, 9- hand-operated valve, 10- downpipe, 11- sampling bottle, 12- waterproof electronic scale, 13- water storage box Motor-driven valve.
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.
