Abstract
The utility model discloses an initial rainwater draining device, which comprises a rainwater collecting well and a rainwater collecting pipe. The initial rainwater draining device is characterized in that a rainwater draining well is arranged on the outside of the rainwater collecting well, a distribution tank is arranged on a partition wall between the rainwater draining well and the rainwater collecting well, the distribution tank is an 'F'-shaped open water tank, a draining port is arranged at one end of the distribution tank, a stroke plate is arranged on the draining port and movably connected with the draining port by the aid of a hinge, and a floating body is arranged on the stroke plate and fixedly connected with the stroke plate by the aid of a transmission rod. Compared with the prior art, the initial rainwater draining device has the advantages of simple structure, low operating cost, convenience in equipment maintenance, low equipment manufacturing cost, realization of automatic draining of initial rainwater and further improvement of rainwater recycling efficiency.
Description
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.
