Background technology

Along with the sustainable development of global economy, society continues to rise to the demand of freshwater resources, and rainwater is as a kind of freshwater resources of preciousness, and it is collected to utilize and becomes very necessary.In city particularly in all kinds of impermeabilities region (roofing, street, sidewalk etc.) of large size city, the occupied space of roofing is large, Runoff is better compared with other overland flow water quality, rainwater is convenient to collection and treatment, therefore Roof Runoff one of potential available water resource especially.But at the rainfall initial stage, rain water on roof carries a large amount of impurity, therefore need abandoned stream to fall a certain amount of roofing early-stage rainwater.

In prior art, most of flow abandoning apparatus can not be realized the automatic flow abandoning of early-stage rainwater, is to adopt valve control for the emptying of early-stage rainwater, needs manual operation, and its process is loaded down with trivial details; Some utilize electrical control to realize the device of early rainwater automatic flow abandoning, although realized automatic flow abandoning, have greatly reduced manpower work, the electronic equipments that adopt more, and technical sophistication, reliability and poor durability, fragile, be difficult for Maintenance and Repair.

Utility model content

The utility model is for avoiding the existing weak point of above-mentioned prior art, a kind of waterpower self-control type early-stage rainwater stream abandoning device is provided, can not realizes automatic flow abandoning and utilize electrical control to realize the problem that the device of early rainwater automatic flow abandoning is fragile, be difficult for Maintenance and Repair to solve existing flow abandoning apparatus.

The utility model is that technical solution problem adopts following technical scheme:

The design feature of the utility model waterpower self-control type early-stage rainwater stream abandoning device is: water tank is set, has and point be in the left and right sides, separate collecting chamber and abandoned stream chamber in described water tank; On the top board of described water tank, be fixedly installed intake chamber, the delivery port of described intake chamber stretches in water tank, in described water tank, the guiding gutter that is undertaken on the water outlet of intake chamber is the bottom that is hinged on intake chamber at middle part by pin, described guiding gutter can be rotated taking pin as rotating shaft in perpendicular, one end of described guiding gutter is the abandoned stream end that stretches to abandoned stream chamber one side, the other end is the collecting terminal that stretches to collecting chamber one side, abandoned stream end at described guiding gutter is fixedly connected with ball float by rigidity hanging stick, and by the valve rod of the hinged abandoned stream valve of push-and-pull rod; Connect downward one section of retaining elbow at the collecting terminal of described guiding gutter, at the end of described retaining elbow ostium excurrens.

The design feature of the utility model waterpower self-control type early-stage rainwater stream abandoning device is also: described water tank is to be separated to form as collecting chamber and abandoned stream chamber by vertical median septum.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, the utility model utilizes lever principle and hydraulic principle to realize the object of early rainwater automatic flow abandoning, has saved the engineering cost of rainwater utilization, is conducive to rainwater catchment system.

2, the utility model does not need to use any electronic equipment and realizes automatic flow abandoning object, simple in structure, energy-conserving and environment-protective, easy to maintenance.

3, the utility model overall structure is stable, meets most of civil engineering installation requirements, and above and below ground is installed and all can.

Number in the figure: 1 intake chamber, 2 guiding gutters, 3 ball floats, 4 push-and-pull rods, 5 rigidity hanging sticks, 6 abandoned stream valves, 7 pins, 8 valve rods, 9 collecting chambers, 10 abandoned stream chambers, 11 water tanks, 12 vertical median septums, 13 retaining elbows.

Detailed description of the invention

In the present embodiment, the form of structure of waterpower self-control type early-stage rainwater stream abandoning device is: in water tank 11, have and point be in the left and right sides, separate collecting chamber 9 and abandoned stream chamber 10, on the top board of water tank 11, be fixedly installed intake chamber 1, the delivery port of intake chamber 1 stretches in water tank 11, in water tank 11, the guiding gutter 2 that is undertaken on the water outlet of intake chamber 1 is the bottom formation lever constructions that are hinged on intake chamber 1 at middle part by pin 7, guiding gutter 2 can be rotated taking pin 7 as rotating shaft in perpendicular, one end of guiding gutter 2 is the abandoned stream end that stretches to abandoned stream chamber 10 1 sides, the other end is the collecting terminal that stretches to collecting chamber 9 one sides, abandoned stream end at guiding gutter 2 is fixedly connected with ball float 3 by rigidity hanging stick 5, and by the valve rod 8 of the hinged abandoned stream valve 6 of push-and-pull rod 4, connect downward one section of retaining elbow 13 at the collecting terminal of guiding gutter 2, at the end of retaining elbow 13 ostium excurrens.

In concrete enforcement, water tank 11 is to be separated to form as collecting chamber 9 and abandoned stream chamber 10 by vertical median septum 12, and intake chamber 1 is to be undertaken in rainwater down pipe, and the draining of collecting chamber is to rainwater-collecting, abandoned stream valve 6 is abandoned stream discharge while unlatching, the volume of abandoned stream chamber 10 is determined according to the abandoned stream amount of roofing early-stage rainwater.

In rainfall stage not, in abandoned stream chamber 10, there is no rainwater, abandoned stream valve 6 cuts out, and guiding gutter 2 is to tilt under the Action of Gravity Field of ball float 3 and abandoned stream end is state as shown in Figure 1 lower than collecting terminal.

At the rainfall initial stage, early-stage rainwater enters abandoned stream chamber 10 by guiding gutter 2, and abandoned stream chamber 10 water levels rise, and ball float 3 rises thereupon, and drives the upwards lifting of abandoned stream end of guiding gutter 2, state as shown in Figure 2;

In the time that guiding gutter 2 is horizontal level, rainwater flows along guiding gutter 2 simultaneously in retaining elbow 13, and forms retaining at retaining elbow 3, state as shown in Figure 3 because inflow is greater than water yield;

Along with the increase of retaining in retaining elbow 3, the weight of retaining makes guiding gutter 2 transmit state as shown in Figure 4 as arm bar, and now, under the effect of push-and-pull rod 4, abandoned stream valve 6 is unlocked, and early-stage rainwater discharge is carried out by abandoned stream valve 6 in abandoned stream chamber 10; Meanwhile, remain on state as shown in Figure 4 because the weight of retaining in retaining elbow 13 makes guiding gutter 2, rainwater flows to collecting chamber 9 by guiding gutter 2, and is discharged and collected by collecting chamber.

After rain stops, the retaining in retaining elbow 13 is immediately by draining aperture round, and guiding gutter 2, ball float 3 and abandoned stream valve 6 recover state as shown in Figure 1, wait for next rainwater-collecting.
