Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, is convenient to be well understood to the utility model, but they do not form restriction to the utility model.
As shown in Fig. 1-Fig. 4, the utility model comprises eddy flow constant current body 7, and eddy flow constant current body 7 comprises the swirl component 7.1 and water diversion part 7.2 that are interconnected; Swirl component 7.1 is the closed circular column construction that two circular block faces 7.11 and a cylinder 7.12 surround; Water diversion part 7.2 is tubulose, tangent with swirl component 7.1 bottom the cylinder 7.12 that water diversion part 7.2 is connected to swirl component 7.1; Water diversion part 7.2 bottom has water inlet 7.21, and one of them circular block face 7.11 of swirl component 7.1 centrally has delivery port 7.13; One of them circular block face 7.11 of swirl component 7.1 is provided with fastening devices, and fastening devices is provided with lifting appliance.
Shown in composition graphs 5-Fig. 9, eddy flow constant current body 7 is fixed on outlet conduit 3 place in manhole 9 by fastening devices, delivery port 7.13 is communicated with outlet conduit 3.Fastening devices comprises operation panel 5 and installing plate 4, operation panel 5 is fixed on one of them circular block face 7.11 of swirl component 7.1, operation panel 5 comprises operation panel body 5.1, and operation panel body 5.1 center has the first through hole 5.2, and operation panel body 5.1 left and right sides is wedge structure 5.3; Installing plate 4 is fixed on manhole 9 inwall, installing plate 4 comprises installing plate body 4.1, installing plate body 4.1 center has the second through hole 4.2, installing plate body 4.1 left and right sides is provided with the dovetail groove 4.3 inserted for wedge structure 5.3, as shown in Figure 6, Figure 7, the wide bottom, notch top of dovetail groove 4.3 is narrow, is provided with sealing ring 8 and seals between installing plate 4 and operation panel 5.
Lifting appliance is the action bars 6 being fixedly connected on operation panel 5 top by the retainer ring 5.4 at operation panel 5 top, and action bars 6 upper end is stretched out outside manhole 9.
In the utility model, the water inlet 7.21 of eddy flow constant current body 7, lower than delivery port 7.13, can tackle greasy dirt, floating thing, preventing pollution and blocking pipe.
The utility model is applicable to outlet conduit 3 and is arranged on higher than place bottom manhole 9 collecting-tank 2, namely a segment distance h is had bottom outlet conduit 3 distance set pond 2, make eddy flow constant current body 7 when mounted, eddy flow constant current body 7 delivery port 7.13 is aimed at outlet conduit 3, in collecting-tank 2, installing space is left to eddy flow constant current body 7 bottom, during installation, on the ground the operation panel 5 of eddy flow constant current body 7 is inserted by action bars 6 in the dovetail groove 4.3 of the installing plate 4 of manhole 9.
Utility model works principle: the utility model eddy flow constant-current device relies on spontaneous eddy current effect to control flow, without the need to moving component.When not having flow, eddy flow constant-current device can serve as water reservoir and overflow downstream line to prevent smell.Because manhole 9 inlet duct 1 is lower than outlet conduit 3, eddy flow constant-current device can tackle greasy dirt that rainfall runoff or flood carry and floating thing enters downstream line.When there is the low rainfall to moderate strength, current can directly by eddy flow constant-current device, and increased by the flow of eddy flow constant-current device, flow velocity also increases.When there is heavy showers or flood, can be increased to by the flow velocity of eddy flow constant-current device makes current produce eddy current in specially designed arc eddy flow constant current body 7, this eddy current can make air concentrate at the orifice center place of outlet and form a cavity, the effective cross section that this cavity actually reduces aperture runner is amassed, be equivalent to reduce orifice diameter, thus reduce rate of discharge.After rainfall stops, water level decreasing, flow velocity reduces until eddy current effect disappears, and eddy flow constant-current device recovers normal.Therefore, when flow is excessive, eddy flow constant-current device volitional check immediately can flow into the flow of downstream line, allows rainwater to be temporarily stored in underground water well or pond, earth's surface, to guarantee that rainwater can enter drainage system lentamente, ensure the normally work such as drainage pipe, Wastewater Treatment Plant.
The content that this manual is not described in detail belongs to the known prior art of professional and technical personnel in the field.
