Description of drawings

Fig. 1 is a structural representation of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the present invention is explained further details, following explanation only is exemplary, does not limit protection scope of the present invention.

With reference to accompanying drawing 1; A kind of rainwater flow-discarding device comprises the little water tank of a closed container 19, three branch fluids that are provided with up and down, 9, early-stage rainwater stream abandoning pipe 13, a later stage rainwater collecting pipe 14 and a floating ball lever mechanism, and each divides fluid upper side to be equipped with three tap holes 3; Be connected with the leader 1 of water inlet on the topmost portion fluid 2; One of them tap hole 3 place connects first flexible pipe, 4, the first flexible pipes, 4 other ends and connects intermediate section fluid 7, and tap hole 3 places connect second flexible pipe 5 in the intermediate section fluid 7; Second flexible pipe, 5 other ends connect the last fluid 8 that divides, and divide a tap hole 3 of fluid 8 to link to each other with little water tank 9 through body 6 at last; There is ball float 12 little water tank 9 inside, and the bottom is provided with the abandoned stream hole that has control valve 17; Early-stage rainwater stream abandoning pipe 13 upper ends are uncovered, and open-mouth is provided with first lid 15; Later stage rainwater collecting pipe 14 upper ends are uncovered, and open-mouth is provided with second lid 16; Floating ball lever mechanism comprises first lever 20 and second lever 21, and wherein first lever, 20 1 ends are connected with and are arranged on ball float 12, and the other end connects first lid, 15, the first balance pivots 10 and is positioned at closed container 19 inner bottom parts; Second lever, 21 1 ends link to each other away from ball float 12 1 ends with first lever, and the other end connects second lid, 16, the second balance pivots, 11 closed container 19 inner bottom parts; Leader 1 is provided with the container top, divides fluid to be provided with in the container 19, and early-stage rainwater stream abandoning pipe 13, later stage rainwater collecting pipe 14 and little water tank 9 are arranged on container 19 inner bottom parts are set.

Leader 1 and branch fluid are on the same axis and through axis body 18 and connect as one.

Dividing fluid in the practice is cylinder, divides fluid and tap hole 3 quantity can be arranged to as required a lot.

Consider cost and application life, little water tank 9 materials are polyvinyl chloride.

Operating principle of the present invention is following: dividing fluid is the core component of whole device, and m shunting cylinder can be arranged.When the rainwater of leader 1 flows to topmost portion fluid 2 through water inlet, on topmost portion fluid 2, have n tap hole 3, along with raising of water level, the water surface is steady gradually, becomes overflow situation gradually, by tap hole 3 overflows.One of them tap hole 3 flows to intermediate section fluid 7 through first flexible pipe 4, similarly afterwards.The spillway discharge that finally flows to little water tank 9 through body 6 is the 1/n of total abandoned stream amount ^m

Little water tank 9 is controlling organization.Total abandoned stream amount is certain, m, and if n is certain, and the dischargeable capacity of then little water tank 9 is also certain.After water in the little water tank is full; Ball float 12 is closed first lid 15 through the effect of first lever 20; Through second lever 21 second lid 16 is opened accordingly simultaneously, when rainwater is stopped the abandoned stream discharging, can be flowed to later stage rainwater collecting pipe 14; Make follow-up clean rainwater effectively stored utilization, thus the purpose of phase rainwater shunting before and after reaching.After precipitation finishes, can the water of abandoning in the little water tank 9 be passed through valve 17 manual emptyings, precipitation then has same process next time.

As for little water tank 4 effective Determination of The Water level; Note: ball float 12 is because the buoyancy of water effect; Up lifting gradually; Make first lid 15 just in time close early-stage rainwater stream abandoning pipe 13 downwards through first lever 20, second lid 16 is upwards opened, so just can confirm the final states water level of little water tank 4 through second lever 21.But effectively water level should guarantee after abandoned stream is accomplished a little more than the final states water level, when rainwater is stopped the abandoned stream discharging, can flow to later stage rainwater collecting pipe 14.

Only be preferred implementation of the present invention below, should be pointed out that under the prerequisite that does not break away from know-why of the present invention, can make some improvement, these improvement should belong to protection scope of the present invention for those skilled in the art.
