Description

A kind of tipping bucket type early-stage rainwater stream abandoning device

Technical field

The utility model belongs to the technical field of rainwater treatment, and in particular to one kind realizes rainwater catchment system, to rainwater The early-stage rainwater stream abandoning device shunted.

Background technology

China is the serious country of shortage of water resources, a water pollution, and the collection and utilization of rainwater are inevitable choices.By Influenceed in by factors such as air, underlying surfaces, the different phase of rainfall duration, rainfall water quality has very big difference, Initial Runoff rain Contain a large amount of pollutants in water, intermediary and later stages rainwater pollution degree is low.To collect the preferable rainwater of water quality, processing rainwater is reduced Difficulty and expense, and pollution of the early-stage rainwater to water body is reduced, early-stage rainwater is typically directly discharged into sewage conduct, is sent into dirty Water factory is handled, and middle and later periods rainwater is collected into utilization.

Existing early-stage rainwater stream abandoning device is divided into " automatic flow abandoning " and " mechanical abandoned stream " by power source；According to abandoned stream principle The polytypes such as positive displacement, half-volume type, Swirling separated, turnover plate type, suitching type, flow-type, rainfall formula can be divided into again.These Early-stage rainwater stream abandoning device respectively has deficiency：The automatic flow abandoning apparatus such as Swirling separated, turnover plate type, suitching type and flow-type machinery are abandoned Stream device can not collect later stage rainwater, and rainwater-collecting efficiency is low；Positive displacement and half-volume type rainwater flow-discarding device floor space be big, Need manual emission drainage tank；Rainfall formula and the cost of flow-type machinery flow abandoning apparatus height, management service are costly, it is also necessary to disappear Consuming electric power.

Utility model content

The problem of existing for prior art, technical problem to be solved in the utility model are just to provide a kind of tipping bucket type Early-stage rainwater stream abandoning device, it effectively can separate early-stage rainwater and middle and later periods rainwater, and simple in construction, low cost, without automatically controlled Part, occupation of land are small, without manual operation.

Technical problem to be solved in the utility model realized by such technical scheme, it include casing, Water inlet pipe, abandoned stream pipe, rain pipe and tipping bucket, water inlet pipe are located at box top, box house of the tipping bucket below water inlet pipe, turned over Struggle against as the triangle bucket of opening upwards；Bottom half side wall rain water pipe, the opposite side wall relative with rain pipe are abandoned Flow tube；Wall box base where rain pipe is equipped with rotating shaft, and the both ends of rotating shaft are provided with clockwork, and tipping bucket bottom seamed edge is consolidated It is scheduled in rotating shaft, abandoned stream water hole is provided with the tipping bucket wall in face of abandoned stream pipe；Filled in the tipping bucket wall upper outside close to rain pipe There is magnet, the different in nature magnet mutually attracted with tipping bucket wall magnet is housed on the wall box where rain pipe.

By adopting the above-described technical solution, having the technical effect that of being obtained of the utility model：Using early-stage rainwater weight, Rotating shaft wind up device restoring force and magnet magnetic force realize exclude early-stage rainwater and collect the middle and later periods rainwater two states from By switching, no electric control gear, reliability is high, takes up an area small, simple in construction, rainwater-collecting rate height；And small volume, it is mountable to rainwater Charge for remittance main or rain perforaled strainer bottom.

Brief description of the drawings

Brief description of the drawings of the present utility model is as follows：

Fig. 1 is structural representation of the utility model under tipping bucket upright state；

Fig. 2 is structural representation of the utility model under tipping bucket rollover states；

Fig. 3 is tipping bucket structural representation of the present utility model.

In figure：1. the clockwork spring of 7. rotating shaft of water inlet pipe 2. abandoned stream pipe, 3. rain pipe, 4. casing, 5. tipping bucket, 6. magnet 8. fills Put 9. abandoned stream water holes.

Embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples：

As shown in Figure 1, Figure 2 and Figure 3, the utility model includes casing 4, water inlet pipe 1, abandoned stream pipe 2, rain pipe 3 and turned over Bucket 5, water inlet pipe 1 are located at the top surface of casing 4, and for tipping bucket 5 inside the casing 4 of the lower section of water inlet pipe 1, tipping bucket 5 is the three of opening upwards Angular bucket；The bottom side wall rain water pipe 3 of casing 4, the opposite side wall relative with rain pipe 3 has abandoned stream pipe 2；Rain pipe 3 The wall box base at place is equipped with rotating shaft 7, and the both ends of rotating shaft 7 are provided with clockwork 8, and the bottom seamed edge of tipping bucket 5, which is fixed on, to be turned On axle 7, abandoned stream water hole 9 is provided with the tipping bucket wall in face of abandoned stream pipe 2；It is equipped with the tipping bucket wall upper outside close to rain pipe 3 Magnet 6, the different in nature magnet attracted with the phase of tipping bucket wall magnet 6 is housed on the wall box where rain pipe 3.

Quantity, size, the position root locality amount of rainfall concrete condition in the abandoned stream water hole 9 determine that abandoned stream water hole 9 can make just Phase rainwater flows out a part before tipping bucket maximum volume is reached, from abandoned stream water hole.

The course of work of the present utility model is：As shown in figure 1, before rainfall starts, tipping bucket 5 is protected under the magneticaction of magnet 6 Hold upright state, rainfall initial stage, Rainfall runoff is smaller, and rainwater is flowed into tipping bucket 5 from water inlet pipe 1, then from the abandoned stream on tipping bucket 5 Water hole 9 flows into abandoned stream pipe 2；Become big with rainfall, when the rainfall for entering tipping bucket 5 is more than the rainfall of outflow out of abandoned stream water hole 9, turn over Bucket 5 in water level be gradually increasing, the center of gravity of tipping bucket 5 gradually moves to left, when rainfall reaches 5 maximum volume of tipping bucket in tipping bucket 5, rainwater weight and The deadweight of tipping bucket 5 is more than the magnetic force of magnet 6,7 upset around the shaft of tipping bucket 5.

As shown in Fig. 2 equivalent to rain pipe 3 is opened after the upset of tipping bucket 5, abandoned stream pipe 2, while the both ends clockwork spring of rotating shaft 7 are closed Clockwork spring is tightened in device 8.Now, the early-stage rainwater in tipping bucket 5 all flows into abandoned stream pipe 2, and rainwater is added to the impulse force of tipping bucket 5 and turned over The deadweight of bucket 5 is more than clockwork spring restoring force, prevents tipping bucket 5 from recovering upright state.Because clockwork spring restoring force is conducted oneself with dignity slightly larger than tipping bucket 5, So when rainfall is reduced to rainwater and is less than clockwork spring restoring force plus the deadweight of tipping bucket 5 to the impulse force of tipping bucket 5, i.e., rainfall runoff is almost During stopping, clockwork spring restoring force drives the rotation of tipping bucket 5 to return to certain angle, recovers the original position of tipping bucket 5 by the attraction of magnet 6.
