Description
Technical field
The utility model relates to rainwater-collecting isolation technics, especially relates to a kind of primary rainwater closure well.
Background technology
Existing drainage system against rain is all that the inspection shaft arranged by ground is flowed in drainage pipe, then enters in receiving water body.Along with increasing of urban atmospheric pollution and ground pollution, rainwater washing away to air and ground before flowing into inspection shaft, water pollution is very serious; Especially early-stage rainwater, its impurity and pollutant are very many, just directly drain in receiving water body, then cause serious pollution by water body if not treated.By early-stage rainwater and intermediary and later stages rainwater separately, and to carry out collecting process to early-stage rainwater be very necessary therefore.
Summary of the invention
The utility model object be to provide a kind of structure simple, easy for installation, without the need to manually operated primary rainwater closure well.
For achieving the above object, the utility model can take following technical proposals:
Primary rainwater closure well described in the utility model, comprise pond body, described pond body diapire is provided with overflow weir, pond body is divided into rainwater-collecting district and overflow area two parts by described overflow weir, the pond body sidewall being positioned at described rainwater-collecting district is communicated with former water water inlet pipe and primary rainwater closure pipe respectively, the diameter of described former water water inlet pipe is greater than the diameter of described primary rainwater closure pipe, the pond body sidewall being positioned at described overflow area is communicated with gutter, the height of described overflow weir is higher than described gutter, former water water inlet pipe and primary rainwater closure pipe, the float-ball type guillotine mechanism for blocking water is provided with in the described rainwater-collecting district at described primary rainwater closure water inlet tube mouth place.
Described float-ball type guillotine mechanism comprises symmetry and is installed in the U-shaped draw-in groove of primary rainwater closure water inlet tube mouth both sides on the body sidewall of described pond and is close to described primary rainwater closure water inlet tube mouth and slides the flashboard be arranged in described U-shaped draw-in groove, described flashboard height is more than or equal to the diameter of described primary rainwater closure pipe, and the upper end of described U-shaped draw-in groove is higher than described primary rainwater closure pipe; Be installed with floating drum in the upper end of described U-shaped draw-in groove, be movably set with ball float in it, be provided with guide chain vertically downward bottom described ball float, described guide chain is connected with described flashboard mutually through the diapire of described floating drum.
The utility model advantage be structure simple, easy for installation, without the need to Artificial Control.The law of buoyancy ball float passing through to be arranged in floating drum is utilized to drive flashboard to complete closure or openness action to primary rainwater closure pipe; At the rainfall initial stage, ball float is not by buoyancy, and primary rainwater closure pipe is in opening, the rainfall intermediary and later stages, ball float buoyancy increases gradually, drives flashboard to move upward, closed primary rainwater closure pipe, automatically, effectively achieves being separated of early-stage rainwater and intermediary and later stages rainwater; Simple and fast is installed, with low cost, stable and reliable operation, the course of work is without the need to by external force, and without the need to Artificial Control, and effective being entered by early-stage rainwater is sent to Wastewater Treatment Plant in primary rainwater closure pipe and is processed, reduce rainwater to the pollution of water body, improve water ecological environment.

Fig. 2 is that the A-A of rainfall initial stage flashboard Fig. 1 when being in non-raised configuration is to sectional view.
Fig. 3 is that the A-A of rainfall middle and later periods flashboard Fig. 1 when being in raised configuration is to sectional view.
Detailed description of the invention
As Fig. 1, 2, shown in 3, primary rainwater closure well described in the utility model, comprise pond body, pond body diapire is provided with overflow weir 1, pond body is divided into rainwater-collecting district 2 and overflow area 3 two parts by overflow weir 1, the pond body sidewall being positioned at rainwater-collecting district 2 is communicated with former water water inlet pipe 4 and primary rainwater closure pipe 5 respectively, the diameter of former water water inlet pipe 4 is greater than the diameter of described primary rainwater closure pipe 5, the pond body sidewall being positioned at overflow area 3 is communicated with gutter 6, the height of overflow weir 1 is higher than gutter 6, the height of primary rainwater closure pipe 5 and former water water inlet pipe 4, the float-ball type guillotine mechanism 7 for blocking water is provided with in the rainwater-collecting district 2 of rainwater intercepting sewer 5 water inlet in the early stage, float-ball type guillotine mechanism 7 comprises symmetry and is installed in the U-shaped draw-in groove 7.1 of primary rainwater closure pipe 5 water inlet both sides on the body sidewall of pond and is close to primary rainwater closure pipe 5 water inlet and slides the flashboard 7.2 be arranged in U-shaped draw-in groove 7.1, flashboard 7.2 is highly more than or equal to the diameter of primary rainwater closure pipe 5, the upper end of U-shaped draw-in groove 7.1 is higher than the height of primary rainwater closure pipe 5, be installed with floating drum 7.3 in the upper end of U-shaped draw-in groove 7.1, be movably set with ball float 7.4 in it, be provided with guide chain 7.5 vertically downward bottom ball float 7.4, guide chain 7.5 is connected with flashboard 7.2 mutually through the diapire of floating drum 7.3.
Operating principle of the present utility model is as follows:
Utilize law of buoyancy, the rainfall initial stage as shown in Figure 2, early-stage rainwater flows in rainwater-collecting district 2 from former water water inlet pipe 4, now in rainwater-collecting district 2, liquid level is lower, ball float 7.4 in floating drum 7.3 is not by buoyancy, and flashboard 7.2 is positioned at below primary rainwater closure pipe 5 under gravity, and primary rainwater closure pipe 5 water inlet is in opening, the menarche of early-stage rainwater, rainwater intercepting sewer 5 water inlet flows out, and is sent to Wastewater Treatment Plant and processes, diameter due to former water water inlet pipe 4 is greater than the diameter of described primary rainwater closure pipe 5, inflow in rainwater-collecting district 2 is greater than water yield, water surface liquid level raises gradually, when in rainfall, during the later stage as shown in Figure 3, liquid level is elevated to floating drum 7.3 inner float ball 7.4 position, ball float 7.4 is subject to buoyancy to floating, drive flashboard 7.2 along U-shaped draw-in groove 7.1 upward sliding by guide chain 7.5, the water inlet of closed primary rainwater closure pipe 5, now only to intake in rainwater-collecting district 2 not draining, when liquid level reaches on overflow weir 1 along place, rainwater will flow into overflow area 3 from overflow weir 1, at the gutter 6 by being arranged on the body sidewall of pond, overflow area 3, in inciting somebody to action, later stage rainwater is discharged, directly enter in receiving water body, complete early-stage rainwater with in, the separating treatment of later stage rainwater, reach and reduce early-stage rainwater to water pollution, improve the object of water ecological environment.
