Description

Early-stage rainwater stream abandoning device

Technical field

The utility model relates to plumbing equipment and rainwater reuse technical field, specifically a kind of early-stage rainwater stream abandoning device of rainwater reuse.

Background technology

In order to save the water source, make full use of the natural resources, people usually adopt rainwater after treatment as various uses such as greening irrigation, fountain moisturizing, structure water scenery, flushing lavatory, laundry carwash, fire-fighting usefulness and groundwater recharges.Because rainwater its own particularity, be that initial rainfall has tangible souring, all kinds of suspensions, pollutant often all concentrate in the rainfall of the first issue millimeter of rainfall, for the better utilization rainwater, alleviate the operating load of rainwater treatment process, generally early-stage rainwater being carried out abandoned stream need not.

At present, generally adopt preferential flow to abandon method abandoned stream well to the abandoned stream of early-stage rainwater, this abandoned stream well is brick or concrete structure, is respectively equipped with rainwater water inlet pipe and outlet pipe in the structure, is provided with the space of a constant volume below water inlet.When rainfall, early-stage rainwater preferentially flows in the headspace of below and carries out abandoned stream, increase along with amount of precipitation, below abandoned stream well moisture storage capacity also increases thereupon, when the water level liquid level arrives the position of drainage tank delivery port, enter the rainwater collecting pit through the rainwater behind the abandoned stream in advance with outlet pipe, thereby realize the purpose of early-stage rainwater stream abandoning.

Though existing rain water drainage technology can realize the purpose of early-stage rainwater stream abandoning, but exist many irrational one sides, because abandoned stream well water inlet pipe and water outlet pipe is in same horizontal level, when the amount of precipitation of rainwater increases suddenly, the drop effect of early-stage rainwater can form very large action of turbulent flow to abandoned stream well inner storing water, be blended into once more in the clear water layer after will the pollutants such as suspension at the bottom of the pond stirring, this just makes the purpose that can't realize abundant abandoned stream in the face of big rainfall the time.If avoid the volume that above-mentioned influence factor just must enlarge the abandoned stream well, reduce the influence of drop turbulent flow as much as possible, but the expansion of abandoned stream well volume makes the initial Split-flow amount also increase in the lump, thereby cause the minimizing of available amount of rainfall, greatly reduce the efficient of rainwater reuse.

The utility model content

The purpose of this utility model is a kind of early-stage rainwater stream abandoning device that designs at the deficiencies in the prior art, it adopts distributing trough that early-stage rainwater is flowed into the rain water drainage well through the abandoned stream mouth, the later stage rainwater enters rainwater by the distributing trough overflow and collects well, realize the automatic flow abandoning of early-stage rainwater, further improve the efficient that rainwater reuse utilizes.

The concrete technical scheme that realizes the utility model purpose is: a kind of early-stage rainwater is abandoned and is stayed device, comprise rainwater collection well, rainwater collecting pipe, be characterized in that rainwater is provided with the rain water drainage well outside collecting well, be provided with distributing trough on the partition wall of rain water drainage well and rainwater collection well, distributing trough is for being the uncovered tank of " cutter " shape, and the one end is provided with the abandoned stream mouth, the abandoned stream mouth is provided with lays one's hand on plate, lay one's hand on plate and the abandoned stream mouth is flexibly connected by hinge, lay one's hand on plate and be provided with buoyancy aid, buoyancy aid by drive link with lay one's hand on plate and fixedly connected.

Described drive link is provided with crash bar, and crash bar is connected with the drive link vertical fixing.

Described abandoned stream mouth is provided with the leak proof seal bar.

The utility model has simple in structure compared with prior art, and the device operating cost is low, and plant maintenance is convenient, and equipment manufacturing cost is low, realizes the automatic flow abandoning of early-stage rainwater, further improves the advantage of the efficient of rainwater reuse utilization.

Fig. 3 ~ Fig. 4 is for implementing illustration.

The specific embodiment

Consult accompanying drawing 1, the utility model comprises rainwater collection well 1, rainwater collecting pipe 11, at the arranged outside rain water drainage well 2 of rainwater collection well 1, on the partition wall 3 of rain water drainage well 2 and rainwater collection well 1 distributing trough 4 is set.

Consult accompanying drawing 2; distributing trough 4 is for being the uncovered tank of " cutter " shape; the one end is provided with abandoned stream mouth 5; abandoned stream mouth 5 is provided with lays one's hand on plate 6; laying one's hand on plate 6 is flexibly connected by hinge 10 with abandoned stream mouth 5; lay one's hand on plate 6 and be provided with buoyancy aid 8; buoyancy aid 8 is the cylinder plastic body of filled with foaming material, buoyancy aid 8 by drive link 7 with lay one's hand on plate 6 and fixedly connected, drive link 7 is provided with crash bar 9; crash bar 9 is connected with drive link 7 vertical fixing; crash bar 9 prevents that the buoyancy aid 8 and the pool wall of rain water drainage well 2 from bumping against, and plays the effect of protection buoyancy aid 8, lays one's hand on plate 6 and can freely be rotated by hinge 10 with abandoned stream mouth 5; make and lay one's hand on plate 6 and open or close, abandoned stream mouth 5 is provided with the leak proof seal bar and makes that to lay one's hand on plate 6 airtight with it.

Consult accompanying drawing 3, the utility model is to install like this and use: distributing trough 4 is installed in rainwater collects on the partition wall 3 of well 1 and rain water drainage well 2, fixed support 12 on the partition wall 3, distributing trough 4 is mounted on the support 12, the uncovered tank of distributing trough 4 is arranged on the rainwater of rainwater collecting pipe 11 belows and collects in the well 1, and the abandoned stream mouth 5 of distributing trough 4 one ends is towards rain water drainage well 2.Early-stage rainwater is flowed in the uncovered tank of distributing trough 4 by rainwater collecting pipe 11; flow into rain water drainage well 2 through abandoned stream mouth 5; this moment is because abandoned stream well 2 is the low water stage state; lay one's hand on plate 6 and be in sagging opening; at this moment crash bar 9 can effectively be protected contacting of buoyancy aid 8 and the borehole wall, prolongs the application life of buoyancy aid 8.

Consult accompanying drawing 4, liquid level in abandoned stream well 2 constantly raises along with the inflow of early-stage rainwater, buoyancy aid 8 also floats gradually with water level, buoyancy aid 8 will be laid one's hand on plate 6 rotations with the water level come-up and be closed abandoned stream mouth 5 gradually, after the early-stage rainwater in the abandoned stream well 2 reaches high water level, lay one's hand on plate 6 abandoned stream mouth 5 is closed automatically, because the effect of buoyancy aid 8 and inside water pressure and the leakproof seal bar on the abandoned stream mouth 5 make and lay one's hand on plate 6 and close from movable sealing with abandoned stream mouth 5.So far, early-stage rainwater stream abandoning is finished, the later stage preferably rainwater collect in the well 1 by the uncovered tank overflow of distributing trough 4 to rainwater, realize the automatic flow abandoning of early-stage rainwater, further improve the efficient that rainwater reuse utilizes.

More than just the utility model being further described, is not in order to the restriction this patent, and all is that the utility model equivalence is implemented, and all should be contained within the claim scope of this patent.
