Through the arrangement mode, rainwater can enter the rainwater inlet device and then is subjected to sufficient diversion and regulation treatment, so that the rainwater is conveyed to corresponding subsequent treatment facilities for classification treatment after the rainwater, the quality of the discharged rainwater is improved, and the influence on the quality of the subsequent receiving water body is reduced.
The invention relates to a diversion and regulation type gully device with a pretreatment function, which has the following specific operation conditions: when the user does not rain, the telescopic gate 19 does not block the second overflow channel between the first regulation chamber 12 and the second regulation chamber 13, the cover plate 17 does not cover the first water filling port 23, and the gravity ball 15 pulls the cover plate 17 through the spring 16 under the action of gravity, so that the return spring 18 is in a torsion state; when raining, rainwater flows to the device from a road and a sidewalk, firstly enters the device through the water permeable well cover 2 at the upper part of the well cavity 1, then enters the water inlet chamber 4 and enters the sedimentation chamber 6 through the grid 5, and at the moment, dregs with larger particle sizes carried in the rainwater are intercepted by the grid 5; then, rainwater enters the sedimentation chamber 6, and as the amount of rainwater entering the chamber increases, the water level of the chamber also increases slowly until the rainwater passes through the inclined plates with the fins, and in the process, vortex is formed when the rainwater passes through the first overflow channels between the inclined plates with the fins, and the vortex enables dregs with smaller particle sizes carried in the rainwater to be gathered and then to be deposited and fall into the sediment hopper 14; while the rainwater treated by the settling chamber 6 overflows into the transition chamber 8 through the overflow channel 22, then enters the second water filling chamber 9 through a third overflow channel on a vertical plate 25 between the transition chamber 8 and the second water filling chamber 9, and the rainwater sequentially fills the telescopic gates 19 through the second water filling ports 24 in the flowing process of the second water filling chamber 9, and water is simultaneously drained from the water draining gaps on the side walls of the telescopic gates 19 in the water filling process, because the water filled into the telescopic gates 19 is far larger than the water draining quantity of the water draining gaps on the side walls of the telescopic gates 19, each telescopic gate 19 is slowly filled, the side walls of the gates gradually descend to the bottoms of the corresponding regulating chambers in the process, and the corresponding regulating chambers are separated into a first regulating chamber 12 and a second regulating chamber 13 which are independent from each other, at this time, the second flow passage between the first regulation chambers 12 and the second regulation chamber 13 is closed, the rainwater flowing through the second regulation chamber 9 is filled into the first regulation chamber 12 except for a very small part of the rainwater still filled into the expansion gates 19 to maintain the drainage amount of the drainage gap thereon, most of the rest of the rainwater is not filled into the expansion gates 19 again, but flows into the first regulation chamber 10 through the third flow passage between the vertical plate 25 between the second regulation chamber 9 and the first regulation chamber 10 and the inner wall of the well chamber 1, in the first regulation chamber 10, the rainwater flows through the first water filling port 23, and fills the first regulation chamber 12 with the rainwater amount filled into the first regulation chamber 12 increasing until the water level reaches the designed water level, the buoyancy of the water received by the gravity ball 15 is equal to the gravity received by the gravity ball, the return spring 18 is reset to form a torsion force to pull the cover plate 17 to reset so as to cover the first water filling port 23, rainwater does not enter the first regulation chamber 12 any more, at this time, the first regulation chamber 12 is filled with the rainwater corresponding to the accumulated rainfall required to be split, then the rainwater enters the second regulation chamber 12, the operation condition of the first regulation chamber 12 is repeatedly carried out in the first regulation chamber 12, when the water level reaches the second water level of the first regulation chamber 12, the rainwater does not enter the second regulation chamber 12 any more, at this time, the second regulation chamber 12 is filled with the rainwater corresponding to the accumulated rainfall required to be split, then the rainwater enters the third regulation chamber 12, at this time, the operation condition of the first regulation chamber 12 is repeatedly carried out in the first regulation chamber 12, when the water level reaches the second water level of the first regulation chamber 12, the rainwater does not enter the first regulation chamber 12, at this time, the rainwater does not enter the first regulation chamber 12, and the rainwater corresponding to the first water level of the overflow pipe 11 is discharged through the first regulation chamber 12, and the rainwater pipeline is not required to be split, at this time, the rainwater flows into the first regulation chamber 12 through the first water pipe 11, and the overflow pipe is not required to be split, and the rainwater flows into the third regulation chamber 12, and the rainwater is discharged through the first regulation chamber 11.
After rain is stopped, rainwater does not enter the rain inlet device of the invention any more, the water drain gap on the side wall of each telescopic gate 19 in the second water filling chamber 9 slowly drains, the elastic side wall contracts, the second flow passage between each first regulating chamber 12 and the corresponding second regulating chamber 13 blocked by each telescopic gate 19 is slowly opened, and the rainwater stored in each first regulating chamber 12 flows into the corresponding second regulating chamber 13 and is finally correspondingly discharged into different municipal drainage pipe network systems at the downstream by the corresponding water outlet pipe 21, so that the rainwater enters different subsequent rainwater treatment facilities for classification treatment.
The device can automatically preprocess, shunt and store rainwater through the process. After rain, the water permeable well cover 2 and the water impermeable well cover 3 can be opened to clean the sediment and intercepted muck in the sediment bucket 14 and the grid 5 respectively.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
