Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, justIn being well understood to the present invention, but they do not form restriction to the present invention.

As shown in Figure 1 and Figure 2, the present invention includes well body 1, described well body 1 is interior arrange heavyChamber, shallow lake 4, the separate chamber in buoyancy tank chamber 5 and 6 three of float chambers, described precipitation Room 4Connect water inlet pipe 2, described buoyancy tank chamber 5, the common outlet pipe 3 that connects in float chamber 6, described floatingBall chamber 6 connects abandoned stream pipe 9, and described abandoned stream pipe 9 mouths of pipe are respectively lower than water inlet pipe 2, water outletManage 3 mouths of pipe, between described mud chamber 4 and buoyancy tank chamber 5, have the first overfall 10, described inBetween mud chamber 4 and float chamber 6, have the second overfall 11, described the first overfall 10Area be less than the area of the second overfall 11, described the first overfall 10, the second overflowMouth 11, all higher than abandoned stream pipe 9 mouths of pipe, is provided with buoyancy tank 8 in described buoyancy tank chamber 5, described ball floatIn chamber 6, be provided with and be communicated to the abandoned stream passage 16 of abandoned stream pipe 9 and logical abandoned stream 16 road junctions can be coveredThe ball float 7 of lid, the weight of described buoyancy tank 8 is greater than the weight of ball float 7, described buoyancy tank 8 withBetween ball float 7, connect by transmission device.

In technique scheme, interior of the orthogonal vertical layout that arranges of described well body 1One barricade 14 and the second barricade 15, surround between described the first barricade 14 and well body 1 inwallMud chamber 4, a part for described the first barricade 14, the second barricade 15 and well body 1 inwallBetween surround buoyancy tank chamber 5, another part of described the first barricade 14, the second barricade 15 withBetween well body 1 inwall, surround float chamber 6. Described the first overfall 10 is opened at the first barricadeIn a part of 14, described the second overfall 11 is opened on another part of the first barricade 14.

In technique scheme, described the second overfall 11 bottoms have sewage overflow in dry seasonMouthfuls 17, described dry season, sewage overflow mouth 17 was offered lower than the second overfall 11. When fine dayDry flow sewage enters accurate abandoned stream well by water inlet pipe 2, after mud chamber's 4 precipitations, passes throughDry flow sewage overfall 17 enters float chamber 6, then discharges by abandoned stream pipe 9. Due to drought streamSewage overflow mouth 17 height are lower than the second overfall 11 and the first overfall 10, dry flow sewageCan not enter buoyancy tank chamber 5, can avoid buoyancy tank chamber 5 spilled water holes 12 to stop up.

In technique scheme, described jockey comprises connection cord, described connection cord one endFixing with buoyancy tank 8, the other end is fixing with ball float 7 through assembly pulley 13.

In technique scheme, between described buoyancy tank chamber 5 and float chamber 6, bottom has sluicingHole 12, the aperture of described spilled water hole 12 is less than the area of outlet pipe 3 and abandoned stream pipe 9 mouths of pipe.

In technique scheme, described buoyancy tank chamber 5 inner bottom parts are provided with buoyancy tank limited block 18.

Rainwater of the present invention enters accurate abandoned stream well by water inlet pipe 2, after mud chamber's 4 precipitations,Enter respectively buoyancy tank chamber 5 and float chamber 6 by the first overfall 10, the first overfall 11.Buoyancy tank 8 is connected by assembly pulley 13 with ball float 7. Because the weight of buoyancy tank 5 is greater than ball floatWeight, under original state, buoyancy tank 8 is in extreme lower position, and ball float 7 is in extreme higher position(being opening), if begin to rain, just rain can be by abandoned stream pipe 9 abandoned streams. Work as rainWhen amount increases gradually, the water level in buoyancy tank chamber 5 raises gradually, and reach and stop abandoned stream water level,Now buoyancy tank 8 is issued to extreme higher position in buoyancy, and (ball float 7 reaches extreme lower positionClosed condition). Because ball float 7 is blocked abandoned stream passage 16, now rainwater can be in float chamber 6Interior gathering, in the time that the interior water level in float chamber 6 is increased to outlet pipe 4 place, rainwater is from outlet pipe 4Discharge, now rainwater has become comparatively clean, has reached pretreated effect. This installs needsWant periodic maintenance, the mud in cleaning mud chamber. Wherein, the first overfall 10, first overflowsThe openings of sizes ratio of head piece 11 and stop abandoned stream water level, can be according to the first rain of different situationsThe volume settings of amount.

It is known that the content that this description is not described in detail belongs to professional and technical personnel in the fieldPrior art.
