With specific embodiment, this utility model is made the most below in conjunction with the accompanying drawings Bright.

As it is shown in figure 1, unpowered Vatch basin of the present utility model, including well body 1, well body 1 the first side wall is provided with confluence of rainwater and sewage water inlet pipe the 2, second sidewall and is provided with and natural water Outlet pipe the 3, the 3rd sidewall bottom of connection offers the abandoned stream mouth 4 connecting abandoned stream pipe 12, abandons Flow tube 12 passes to sewage treatment plant, is provided with ball float cut-off equipment 5, in well body at abandoned stream mouth 4 Being provided with fixed weir 6 at abandoned stream mouth downstream, the close outlet pipe mouth of pipe, fixed weir 6 is arranged over Normality is that the floating box type upstream closed controls weir gate 7, and fixed weir 6 extends upwardly to from shaft bottom Sealing when closed with control weir gate 7 lower end, floating box type upstream and coordinate, fixed weir 6 top is high Height bottom degree not higher than abandoned stream mouth 4.Between fixed weir 6 and outlet pipe 3, shaft bottom is along stream The inclined-plane 11 that direction, road is downward-sloping, inclined-plane 11 lowest part is concordant with at the bottom of outlet pipe 3 pipe. Direction from left to right during water (flow) direction is Fig. 1 in the present embodiment.

As in figure 2 it is shown, ball float cut-off equipment 5 includes being arranged on well body 1 the 3rd sidewall Swivel plate 51, is hinged on by abandoned stream mouth 4 side by hinge 54 in the middle part of described swivel plate 51, One end of described swivel plate 51 is provided with ball float 52, the other end is and opening that abandoned stream mouth 4 coordinates Closing plate 53.Well body 1 the 3rd sidewall above swivel plate 51 is provided with the first gag lever post 55 He Second gag lever post 56, is provided with for being connected between the first gag lever post 55 with the second gag lever post 56 Support bar 57, when open and close plate 53 abandoned stream mouth 4 is fully opened time, described keying plate 53 Contact with the first gag lever post 55, when opening and closing plate 53 and abandoned stream mouth 4 being completely covered, described Open and close plate 53 to contact with the second gag lever post 56.Hinged between swivel plate 51 and well body sidewall Point is in the top by abandoned stream mouth 4 side.First gag lever post 55 and the second gag lever post 56 make rotation Flap 51 is only capable of rotating, accurately to abandoned stream in the range of two gag lever posts limit around hinge The folding condition of mouth 4 is adjusted.

As shown in Fig. 3 and Fig. 6-7, floating box type upstream controls weir gate 7 and includes being located in well body Buoyancy tank room 704 and the rotary shaft 701 be located between well body 1 the 3rd sidewall, the 4th sidewall, Buoyancy tank room 704 by the second sidewall, the 3rd sidewall and two sides respectively with the first side wall, the 4th side The buoyancy tank room sidewall 705 that wall is oppositely arranged enclose connection formed, close on abandoned stream mouth 4 side, Buoyancy tank room sidewall 705 top relative with the first side wall is provided with a breach, and this breach is floating Chamber water inlet 706, closes on the buoyancy tank room that the side of outlet pipe 3 is relative with the 4th sidewall The bore buoyancy tank room apopore 707 less than water inlet 706, buoyancy tank it is provided with bottom sidewall 705 Room apopore 707 is provided with check-valves, and in check-valves makes buoyancy tank room 704, current can only be outside Discharge, it is impossible to enter from buoyancy tank room apopore 707.Rotary shaft 701 is respectively fixed at two ends with It is positioned at the buoyancy tank 702 of buoyancy tank room 704 and both sides of the edge and the 4th sidewall, the 4th sidewall phase To buoyancy tank room sidewall 705, close-fitting gate 703, buoyancy tank 702 and gate 703 It is located on rotary shaft 701 downstream.The water inlet height of water level of buoyancy tank room water inlet 706 is floating Box upstream controls weir gate and opens height of water level, i.e. warning line, when weir gate upper pond level arrives When reaching warning line, current pour into rapidly buoyancy tank room 704, and buoyancy tank 702 floats and drives gate 703 rotate unlatching, when upper pond level is less than warning line, no longer have water to enter buoyancy tank room 704, current are discharged from buoyancy tank room apopore 707, and buoyancy tank 702 sinks to driving gate 703 Rotate and close.Buoyancy tank room water inlet 706 is highly not less than keying plate 53 by complete for abandoned stream mouth 4 Ball float 52 bottom level during all standing, floating box type upstream controls weir gate 7 and is closed Time gate 703 rise and be not less than outlet pipe 3 and rise.The first side wall in the present embodiment, second Sidewall, the 3rd sidewall, the 4th sidewall are respectively in Fig. 3 about well body four sides sidewall up and down.

As shown in Figure 4, on relative with the 4th sidewall buoyancy tank room sidewall the 705, the 4th sidewall Being equipped with sealing plate 8, gate 703 both sides are provided with L-type side sealing strip 9, and side seals The side that a bar 9 wherein arm and gate 703 close on abandoned stream mouth 4 is fitted and connected, another arm to Updrift side bending and end are connected with sealing plate 8, and side sealing strip 9 is fitted in lock Door 703 sides are concordant with gate 703 upper and lower side, and sealing plate 8 covers gate 703 when cutting out Corresponding region.Side sealing strip 9 and sealing plate 8 are elastomeric material, make gate 703 In off position with buoyancy tank room sidewall the 705, the 4th sidewall tight seal of both sides.

The L-type sealed bottom bar 10 coordinated with fixed weir 6 upper end it is provided with bottom gate 703, A L-type sealed bottom bar 10 wherein arm is fitted and connected with gate 703 bottom surface, and another arm is vertical Downwardly extend in gate 703 bottom surface.When gate 703 is closed, sealed bottom The arm that bar 10 is wherein fitted with gate 703 bottom surface seals laminating with fixed weir 6 upper surface, Another arm seals laminating, when fixed weir 6 downstream liquid level is the end of to the side in fixed weir 6 downstream During portion's sealing strip 10, hydraulic pressure is by an arm of sealed bottom bar 10 with fixed weir 6 side-fit Tightly laminating fixed weir 6 side, better tightness.

Operation principle of the present utility model is:

During dry season, it is closed as it is shown in figure 1, floating box type upstream controls weir gate 7, The neighbouring one end opening and closing plate 53 of ball float cut-off equipment 5 gag lever post 55 contacts with swivel plate 51 Time spacing, it is shown in a fully open operation, when the liquid level in Vatch basin well body raises, on ball float 52 The floating plate 51 () that is rotated rotates, ball float cut-off equipment 5 aperture in Fig. 1 counterclockwise The least, now sewage is directly dammed to abandoned stream pipe 12 and is flowed to sewage treatment plant.

When heavy showers occurs, in Vatch basin well, water level rises, as it is shown in figure 5, ball float cuts Stream device 5 opens and closes plate 53 and gradually overlaps with abandoned stream mouth 4 until abandoned stream mouth 4 is closed, and dams The liquid level of well continues to rise.So far floating box type upstream control weir gate 7 is constantly in closed mode, When the water level of well body 2 constantly rises to water inlet water level (the warning water of buoyancy tank room water inlet 706 Position), current pour into rapidly buoyancy tank room 704, and buoyancy tank 702 floats and drives gate 703 rotation to open Opening, as shown in Figure 8, later stage rainwater enters natural water by outlet pipe 3.Fixed weir 6 The inclined-plane 11 in downstream makes the rainwater of whole well body 1 drain noresidue.When rainfall terminates, cut In stream well well body 1, water level is gradually reduced, and ball float cut-off equipment 5 is slowly opened；Buoyancy tank room 704 Interior water slowly flows out from apopore 707, and buoyancy tank 702 drives gate 703 to close after sinking, Floating box type upstream controls weir gate 7 and closes reset, as shown in Figure 9.

When natural water liquid level rise pour in down a chimney to Vatch basin time, downstream peak level not over Rising of outlet pipe 3, owing to floating box type upstream controls top when weir gate 7 is closed Height be not less than the height at outlet pipe 3 top, so can prevent under in off position pouring in down a chimney Generation.
