Embodiment
Shown in Figure 1, automatic sampling system for storm runoff in small watershed of the present invention is a weir on the small watershed of setting area, and inspection well, weir plate and aqueduct be set in the end, the correspondence position setting of aqueduct below is drawn water, is shunted and gather three part bodies and forms, the mechanism of wherein drawing water is made of the ball-cock assembly 15 and the travel switch 20 that are provided with in water pump 17 that is provided with in weir and the inspection well 23, water pump stops pumping in both cases, and 1, decline of water table to the ball-cock assembly pull bar 16 in the weir can not contact with travel switch 20; 2, collecting mechanism is finished a collection period, and promptly the branch water management is spiraled and circled.
Diversion mechanism shown in Fig. 1,2,3,4,5 is driven the flow-dividing control dish and is regularly rotated by motor 11, travel switch 7, timing relay J, and the flow-dividing control dish rotates and promptly finishes a collection period week, is stopped by torsion bar switch 13 control motors 11 again.
Branch water management dish is by motor 11, gear 9,8 and constitute with gear turntable 12, disk 22, distributive pipe 6 and the travel switch 7 of gear 8 coaxial settings, torsion bar switch 13, gear turntable 12 revolutions move a tooth, the contact of shake-up travel switch once, travel switch 7 disconnects, motor suspends, set time out by timing relay J simultaneously, gear turntable rotated a tooth again when motor turned round once more, running and so forth, distributive pipe 6 can be annotated the water sample of people's unit interval continuously in each bypass channel 5 of water diversion disk 14.
