Preferably, the floating ball 21, the linkage assembly 22 and the valve plate 23 are all made of stainless steel, the floating ball 21 is phi 50, and the valve plate 23 is phi 130.
In the initial state, the floating ball 21 is positioned at the bottom of the rainwater chamber 11, the through hole 102 is closed by the valve plate 23, at this time, the rainwater chamber 11 is not communicated with the sewage chamber 12, after the runoff rainwater enters the rainwater chamber 11, the liquid level in the rainwater chamber 11 rises, the floating ball 21 floats upwards along with the rising of the liquid level, the floating ball 21 is connected with the linkage assembly 22, the linkage assembly 22 is driven to rotate after the rising of the floating ball 21, the valve plate 23 is driven by the linkage assembly 22 to rotate, the valve plate 23 is gradually far away from the through hole 102 and gradually closes the sewage outlet 105, the valve plate 23 is far away from the through hole 102 on the partition 101 and closes the sewage outlet 105, the rainwater chamber 11 is communicated with the sewage chamber 12, and the rainwater in the rainwater chamber 11 can enter the sewage chamber 12 through the through hole 102 on the partition 101 and is discharged through the rainwater outlet 106 on the sewage chamber 12.
The working process of the rain sewage diversion device provided by the invention is as follows:
When no rainfall occurs, the floating ball 21 is positioned at the bottom of the rainwater chamber 11, the valve plate 23 is maintained in a state of closing the through hole 102 on the partition plate 101 under the gravity action of the floating ball 21, the sewage outlet 105 is in an open state, and sewage which is introduced into the sewage chamber 12 from the converging pipeline interface 104 is directly discharged into a sewage pipeline from the sewage outlet 105.
During the early period of rainfall, the initial rainwater enters the rainwater chamber 11 through the rainwater inlet 103 on the rainwater chamber 11, the liquid level in the rainwater chamber 11 gradually rises to drive the floating ball 21 to float upwards, the valve plate 23 at the through hole 102 on the partition plate 101 is in a slightly opened state, part of the initial rainwater enters the sewage chamber 12 from the through hole 102 on the partition plate 101, the liquid level in the sewage chamber 12 is lower than the rainwater outlet 106 due to smaller rainfall entering the sewage chamber 12, and the initial rainwater entering the sewage chamber 12 and the mixed rainwater and sewage discharged into the sewage chamber 12 from the confluence pipeline interface 104 are discharged from the sewage outlet 105. In the early stage of rainfall, the mixed rain water discharged from the confluent pipe joint 104 into the sewage chamber 12 is mixed water of initial rain water and sewage, and the concentration of initial rain water pollutants for flushing surface source pollution is high, so that the mixed rain water also needs to be discharged from the sewage outlet 105 to a sewage plant for treatment.
When the rainfall is larger and larger, the floating ball 21 continues to float upwards, the through hole 102 on the baffle 101 is completely opened, the valve plate 23 closes the sewage outlet 105, a large amount of middle-late rainwater in the rainwater chamber 11 enters the sewage chamber 12, the liquid level in the sewage chamber 12 continues to rise, when the liquid level exceeds the height of the rainwater outlet 106, a large amount of middle-late rainwater is discharged from the rainwater outlet 106, at the moment, although the converging pipeline interface 104 is filled with mixed rainwater and sewage, the sewage amount in the rainwater and sewage is smaller than the large amount of rainwater entering the sewage chamber 12, and can be ignored.
In the late period of rainfall, the rainfall is smaller and smaller, the liquid level in the rainwater chamber 11 is gradually reduced, the valve plate 23 is gradually far away from the sewage outlet 105, the through hole 102 on the partition plate 101 is gradually closed, and sewage entering the sewage chamber 12 is discharged from the sewage outlet 105.
Because of the high concentration of initial rainwater contaminants in flushing the non-point source of contamination, initial rainwater is not recommended to be directly discharged from the rainwater outlet 106 to a rainwater pipe network or other water storage device or the like, but is required to be discharged into a sewage treatment facility together with sewage for sewage treatment. The middle and late stage rain water contaminant concentration is low and can be discharged through the rain water outlet 106.
According to the rainwater and sewage diversion device, the initial rainwater and sewage are discharged from the sewage outlet 105 for purification treatment, the rainwater with low concentration of pollutants in the middle and later stages is directly discharged into a rainwater pipe network or is connected into other water storage devices for recycling water resources, so that the diversion of the rainwater and the sewage is realized, the diversion of the initial rainwater and the middle and later stage rainwater is realized, the sewage treatment pressure is reduced, and the recycling rate of the water resources is improved.

The diameter of the first wheel 221 is larger than the diameter of the second wheel 222. The synchronous rotation angle ratio of the first linkage shaft 224 to the second linkage shaft 225 is 1:3. In the initial state, the included angle between the first linkage shaft 224 and the partition 101 is 30 degrees, and when the floating ball 21 floats upwards to drive the first linkage shaft 224 to rotate by 30 degrees, the second linkage shaft 225 rotates by 90 degrees, so that the valve plate 23 just rotates from the vertical state to the horizontal state to close the sewage outlet 105. When the floating ball 21 continues to float upward, the first linkage shaft 224 is not rotated any more by the limit action of the partition 101, and the valve plate 23 is kept in a state of closing the sewage outlet 105.

By arranging the water baffle 121 in the sewage chamber 12, rainwater can be discharged from the rainwater outlet 106 when the rainfall reaches a certain amount, so that the diversion of the initial rainwater and the middle-late rainwater can be controlled more accurately, and after the water baffle 121 is arranged, the rainwater outlet 106 can be arranged at the lower part of the side wall of the second chamber 123, so that the rainwater in the second chamber 123 can be completely discharged.
In one embodiment, as shown in fig. 1 and 2, the rainwater inlet 103 is opened at the top of the rainwater chamber 11, and a grid plate 107 is provided at the rainwater inlet 103. The top of box 10 is equipped with well lid 108, and well lid 108 and box 10 are supporting to be used, and the trompil is seted up to the position that well lid 108 corresponds rainwater room 11 and is formed rainwater import 103, supplies runoff rainwater to get into rainwater room 11, and the grid plate 107 that rainwater import 103 department set up can preliminary interception pollutant before the runoff rainwater gets into rainwater room 11. Preferably, the manhole cover 108 is made of composite resin, the thickness of the grid plate 107 is 30mm, and the center distance between adjacent grids is 25mm.
Optionally, the side wall of the rainwater chamber 11 is further provided with a standby rainwater interface 109, and the standby rainwater interface 109 is used for connecting a rainwater pipe, so that the rainwater can not directly enter the rainwater chamber 11 from the rainwater inlet 103. Preferably, the back-up rain water interface 109 is sized phi 110.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
