In a typical embodiment of the present invention, as shown in fig. 1, a rainwater recycling device for road gullies comprises a gully 11, a rainwater recycling pipe 1 and an initial rainwater drainage pipe 2 are arranged at the inner side of the gully 11, the rainwater recycling pipe 1 is higher than the initial rainwater drainage pipe 2, the rainwater recycling pipe 1 is perpendicular to the gully 11, the inner diameter of the rainwater recycling pipe 1 is larger than the inner diameter of the initial rainwater drainage pipe 2, an upper layer rainwater grate 8 is arranged at the inner side of a gully 12 at the gully of the gully 11 through a well ring 10, the upper layer rainwater grate 1 has the same structure as the existing common rainwater grate and is not described again, a lower layer filtering net 3 is arranged below the upper layer rainwater grate 9, the lower layer filtering net 3 is preferably a lower layer steel filtering net, the lower layer filtering net 3 is U-shaped, the hole of the upper layer rainwater grate 8 is larger than the hole of the lower layer filtering net 3, and the upper layer rainwater grate 8 is connected with the lower layer filtering net 3 through a cross beam, the vertical setting of lintel 9, for erecting the roof beam, not only made things convenient for the clearance to lower floor's filter screen 3, but also can open rainwater well's superstructure (upper rainwater grate and lower floor's filter screen) fast when the desilting, the reason that sets up lower floor's filter screen 3 is because the initial stage rainwater has more impurity, its lateral part mainly through upper rainwater grate 8 flows into rainwater well 11, less impurity passes upper rainwater grate 8 and gets into rainwater well 11, consequently, set up the lower floor's filter screen of U type, an initial stage rainwater for further getting into from the lateral part filters.
Or in another embodiment, the lower surface of the lower layer filter screen is provided with a convex part for matching with a support piece arranged in the rainwater well, the support piece is a rectangular frame arranged on the side wall of the rainwater well, and the rectangular frame is provided with a clamping groove matched with the convex part, so that the lower layer filter screen is stably supported.
In this embodiment, the preferred 5mm of hole size of lower floor's filter screen, not only can effectively filter impurity like this, can guarantee the velocity of flow of initial stage rainwater moreover.
The device also comprises a rainwater recycling pipe 1 arranged on the rainwater well and an initial rainwater abandoning pipe 2 lower than the rainwater recycling pipe 1, wherein the bottom of the initial rainwater abandoning pipe 2 is higher than the bottom of the rainwater well 11, which is convenient for arranging a sliding plate 7 and depositing sundries such as silt in the rainwater well 11 for periodic treatment, so that the sundries such as the silt can not enter the initial rainwater abandoning pipe 2, thereby reducing the pollution to water body, the rainwater well 11 is vertically provided with sliding ways 6 at two sides of the initial rainwater abandoning pipe 2, the sliding ways 6 are U-shaped sliding ways, the openings of the sliding ways at two sides of the initial rainwater abandoning pipe 2 are oppositely arranged, the sliding plate 7 can slide through the sliding ways 6, the sliding plate 7 is provided with a sliding plate opening, when the opening 13 of the sliding plate is overlapped with the opening of the initial rainwater abandoning pipe 2, the rainwater flows out through the initial rainwater abandoning pipe 2, when the, as shown in fig. 4 and 5, the initial rainwater drain pipe 2 is blocked by the slide plate 7, and rainwater does not flow out from the initial rainwater drain pipe.
The reason why the sliding plate 7 can move up and down along the slideway 6 is that the floating balls 4 are arranged at the top of the sliding plate 7, the two floating balls 4 are arranged symmetrically left and right relative to the sliding plate, the rainwater rises gradually in the rainwater well 11 along with the increase of the rainwater, the floating balls 4 rise along with the rise of the rainwater surface, thereby driving the sliding plate 7 to move relative to the slideway 6, realizing that the opening of the sliding plate is higher than the initial rainwater discharge pipe 2 step by step, wherein, a limit column 5 is arranged on the side wall of the catch basin 11 between the rainwater recovery pipe 1 and the initial rainwater abandon pipe 2, be used for carrying on spacingly to slide 7 in the top, the distance that 2 sockets of flow tube were abandoned to spacing post 5 and initial stage rainwater apart from the distance of 7 tops of slide 13 bottoms of slide, spacing post 5 abandons the height of 2 sockets of flow tube apart from less than or equal to slide 7 with the initial stage rainwater, not only carries on spacingly to the slide, guarantees moreover that slide 7 abandons the orificial sheltering from of flow tube to the initial stage rainwater.
It should be noted that the floating ball 4 is a plastic ball with a set volume, the floating balls on both sides have the same mass and volume, the floating ball 4 is connected with the sliding plate 7 through a fixed rope, and the sliding plate is provided with a small hole connected with the fixed rope, so that the replacement of the floating ball can be realized; the limiting column 5 can be a fixing bolt or other cylindrical structural members, and one or more limiting columns 5 can be arranged.
The method for recovering rainwater at the road rainwater inlet comprises the following steps:
the initial rainwater enters the rainwater well through the upper layer rainwater grate and is secondarily filtered through the lower layer filter screen;
the initial rainwater is gradually accumulated in the rainwater well, at the moment, the opening of the sliding plate is communicated with the initial rainwater discarding pipe, and as shown in figures 2 and 3, the initial rainwater is discharged out of the rainwater well through the initial rainwater discarding pipe, so that the initial rainwater discarding is realized;
along with the gradual accumulation of rainwater in a rainwater well, the water surface height gradually rises, the lower sliding plate is driven by the lifting part to move upwards relative to the slide way, and the opening of the sliding plate is staggered with the initial rainwater discarding pipe until the opening of the sliding plate is higher than the pipe orifice of the initial rainwater discarding pipe;
the rainwater rises gradually, impurities carried by the rainwater in the middle period are precipitated gradually in the process, and the rainwater is recovered through the rainwater recovery pipe when the height of the rainwater reaches the height of the rainwater recovery pipe gradually;
along with the gradual reduction of rainwater, the rainwater can't retrieve through the rainwater recovery pipe again, because of there is the space between slide and the initial stage rainwater abandon a tub, the rainwater is gradually abandoned a tub outflow through the initial stage rainwater, and the rainwater surface of water progressively reduces, and the floater moves down corresponding drive slide and moves down, abandons a tub intercommunication with the initial stage rainwater until slide trompil, and the rainwater is abandoned a tub outflow from the initial stage rainwater gradually like this.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
