Description
Technical field
The utility model relates to rainwater recycle and utilizes technical field, particularly relates to a kind of rainwater flow-discarding device being applicable to continuous several times rainfall.
Background technology
Rain water drainage, also known as rain early-stage split-flow, is mainly used in rainwater-collecting secondary utilization system.When generally referring to the rainwater collected in roofing, hardened ground, lawn and other rainwater-collecting media, because incipient rainwater all can contain impurity, as birds droppings, paper scrap, the assorted pollutant such as dirt, greasy dirt, so incipient part rainwater needs with flow abandoning apparatus, or abandoned stream well does one it and abandons, and then rainwater clean after collecting.If it is bad that rain early-stage split-flow does, allow impurity flow into catch-basin or storage tank, not only can strengthen the working strength of strainer, cause plugged filter, and long-time after, Impurity deposition is at the bottom of pond, bring very large trouble to the cleaning work in later stage, cause whole system to be paralysed.
Existing its basic functional principle of electronic control type rainwater flow-discarding device is: setting abandoned stream flow, is directed into early-stage rainwater in abandoned stream well, when Rainwater Quality reaches recyclable standard, closes to the pipeline of abandoned stream well, rainwater is imported system for reclaiming rainwater.This rainwater flow-discarding device can accurately control abandoned stream flow, but in the middle of on the same day (in 24 hours), if there is repeatedly rainfall, then each rainwater-collecting all needs to carry out abandoned stream process, and in fact after the first rainfall in the inherence of 24 hours, follow-up rainfall water quality can both reach the standard directly recycled, without the need to carrying out abandoned stream process, existing this rainwater flow-discarding device can cause rainwater-collecting thorough, wastes valuable rainwater resource, underaction, meticulous.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of structure simple, when continuous several times rainfall without the need to repeatedly carrying out the rainwater flow-discarding device of abandoned stream.
In order to achieve the above object, the technical solution of the utility model is: a kind of rainwater flow-discarding device being applicable to continuous several times rainfall, comprise water inlet pipe, sewage well, collecting-tank, two motor operated valves, flow meter/rainfall gauge, timer and PLC, described flow meter/rainfall gauge is for calculating the abandoned stream flow through water inlet pipe, described water inlet pipe is communicated with collecting-tank respectively with described sewage well, described two motor operated valves are divided into the entrance of described sewage well and the entrance of collecting-tank, described PLC and described flow meter/rainfall gauge, described two motor operated valves and described timer-signals connect.
Preferably, water-tight device is provided with in the periphery of described PLC, timer and described two motor operated valves.
Compared with prior art, the utility model has the advantage of, the utility model is controlled abandoned stream flow accurately by PLC, flow meter/rainfall gauge, improves the precision of rainwater flow-discarding device; When there is continuous rainfall in 24 hours, controlled by timer, only in first rainfall collection process, carry out abandoned stream, follow-up rainwater is directly collected, can either ensure that the water quality of the rainwater collected meets standard and do not cause waste again, its structure is simple, cost is low and rainwater-collecting mode flexible, and collecting amount is large.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation being applicable to the rainwater flow-discarding device of continuous several times rainfall of the utility model.
In figure: 1 water inlet pipe, 2 sewage well, 3 collecting-tanks, 4 motor operated valves, 5 timers, 6 flow meters/rainfall gauge, 7 PLC.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, structure of the present utility model and principle are described further.
As shown in Figure 1, a kind of rainwater flow-discarding device being applicable to continuous several times rainfall of the present embodiment, comprise water inlet pipe 1, sewage well 2, collecting-tank 3, two motor operated valves 4, flow meter/rainfall gauge 6, timer 5 and PLC 7, described flow meter/rainfall 6 is for calculating the abandoned stream flow through water inlet pipe 1, described water inlet pipe 1 is communicated with collecting-tank 3 respectively with described sewage well 2, described two motor operated valves 4 are divided into the entrance of described sewage well 2 and the entrance of collecting-tank 3, described PLC 7 and described flow meter/rainfall gauge 6, described two motor operated valves 4 and described timer 5 signal connect.The rainwater flow-discarding device of this embodiment is controlled abandoned stream flow accurately by PLC 7, flow meter/rainfall 6, improves the precision of rainwater flow-discarding device; When there is continuous rainfall in 24 hours, being controlled by timer 5, only in first rainfall collection process, carrying out abandoned stream, follow-up rainwater is directly collected, can either ensure that the water quality of the rainwater collected meets standard and do not cause waste again, rainwater-collecting mode is flexible, and collecting amount is large; Its structure is simple, and electron-like components and parts such as such as two motor operated valves 4, flow meter/rainfall gauge 6, timer 5 and PLC 7 all adopt product ripe on the market, makes flow abandoning apparatus have low cost very.
Wherein, water-tight device (not shown) is provided with in the periphery of described PLC 7, timer 5 and described two motor operated valves 4.By arranging water-tight device in key components and parts periphery, the ability that component prevent water logging can be promoted further, guarantee the reliability of rainwater flow-discarding device.
The specific works process of the rainwater flow-discarding device of the present embodiment is: first in PLC 7, preset rain water drainage flow, the motor operated valve 4 of sewage well 2 entrance is in open mode, the motor operated valve 4 of collecting-tank 3 entrance is in closure state, abandoned stream rainwater is first abandoned and is entered sewage well 2, when flow meter/rainfall gauge 6 detects that abandoned stream flow reaches preset value, the Pneumatic gate valve 4 of PLC 7 control of sewage disposal 2 well entrance closes, the Pneumatic gate valve 4 of entrance, domination set pond 3 is opened, and collecting-tank 3 starts to collect clean rainwater; Timer 5 starts timing simultaneously, and in 24 hours, timer 5 makes two electromagnetic valve 4 states not change by PLC 7, follow-up rainfall just no longer carries out abandoned stream, and after 24 hours, timer returns to original state, if rainfall again, then again successively carry out abandoned stream, collection process.
Apply specific embodiment herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.The above is only preferred embodiment of the present utility model, should be understood that, due to the finiteness of literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, under the prerequisite not departing from the utility model principle, some improvement, retouching or change can also be made, also above-mentioned technical characteristic can be combined by rights; These improve retouching, change or combination, or the design of invention and technical scheme are directly applied to other occasion without improving, and all should be considered as protection domain of the present utility model.
