When raining, the rainwater with larger initial pollution degree flows into the lower side space from the through hole, and is transmitted to a sewage treatment plant along with sewage through the sewage outlet pipe of the split-flow connector. Along with the rainwater accumulation in the lower side space, the pontoon assembly positioned in the lower side space floats upwards and seals the through hole. Then, the space on the upper side of the rainwater is accumulated and floats upwards, and the floating ball drives the rotary valve plate to open the rainwater transmission pipe. Thereby realizing the diversion of rain and sewage. When the rainwater transmission pipe is blocked, the liquid level in the upper side space continuously rises, the floating ball continuously floats and drives the jacking block to slide, the jacking block contacts the starting key switch, the starting key switch drives the water pump to operate, the water pump accelerates the drainage of water in the lower side space, the liquid level in the lower side space descends, the pontoon assembly descends along with the descending and opens the through hole, and rainwater accumulated in the upper side space flows into the lower side space from the through hole and is drained along with the sewage in the lower side space.

The top wall of the water receiving box 3 is provided with a water receiving opening 31 below the rainwater inlet 111, the water receiving opening 31 being adapted to receive rainwater from the rainwater inlet 111. It will be appreciated that rainwater flows into the rainwater chamber 11 through the rainwater inlet 111 and then flows into the water receiving box 3 through the water receiving opening 31.

The water receiving box 3 is internally provided with a vertical plate 32, the vertical plate 32 extends in the front-rear direction, the front end and the rear end of the vertical plate 32 are respectively connected with the front side wall and the rear side wall of the water receiving box 3, a first flow channel 35 is formed between the vertical plate 32 and the water receiving box 3, the peripheral wall of the water receiving box 3 is provided with a water outlet 36 adjacent to the vertical plate 32, and a second flow channel 37 is formed between the vertical plate 32 and the water outlet 36.

The bottom end of the filter plate 6 is provided with a first baffle 62 located in the first flow channel 35 and a second baffle 63 located in the second flow channel 37, and the water receiving box 3 has a first position and a second position when slid in the rain chamber 11.

In the first position, the water receiving box 3 is adjacent to the rainwater inlet 111, the first baffle 62 closes the first flow passage 35, the second baffle 63 opens the second flow passage 37, and rainwater of the water receiving box 3 flows into a space defined by the filter plate 6, the first baffle 62 and the water receiving box 3. Then, the rainwater passes through the filter sheet 6 and is filtered by the filter sheet 6, and the filtered rainwater flows into the rainwater chamber 11 through the second flow passage 37 and the water outlet 36, and is discharged outside through the first drain pipe 112. At the same time, sewage can also flow into the sewage chamber 12 from the water inlet pipe 121 and then be discharged through the second water outlet pipe 122. Thereby realizing the diversion of rain and sewage.

When the filter plate 6 is blocked, dirt and rainwater are accumulated in a space formed by surrounding the filter plate 6, the first baffle plate 62 and the water receiving box 3, along with continuous inflow of rainwater in the space, the rainwater drives the water receiving box 3 to move downwards under the action of gravity, the water receiving box 3 drives the first sliding block 33 to move downwards, and when the first sliding block 33 slides to the limit position, the water receiving box 3 is positioned at the second position. In the second position, the water receiving box 3 is adjacent to the partition 5, the first baffle 62 opens the first flow passage 35, and the second baffle 63 closes the second flow passage 37. The rainwater in the space formed by the filter plate 6, the first baffle plate 62 and the water receiving box 3 is flushed out by the first flow channel 35 and is pressed on the blocking plate 2, so that the blocking plate 2 is forced to open the water through hole 51 under the action of water pressure, at the moment, the water through hole 51 is communicated with the first flow channel 35, and the rainwater is flushed into the sewage cavity 12 by the water through hole 51 and is discharged along with the sewage. Thereby realizing the absorption of rainwater. In addition, when rainwater in a space formed by the enclosing of the filter plate 6, the first baffle plate 62 and the water receiving box 3 is flushed out, dirt on the surface of the filter plate 6 is flushed out, and therefore, the blockage of the filter plate 6 is reduced. In addition, at this time, since the second flow passage 37 is closed, rainwater will accumulate between the second flow passage 37 and the filter plate 6, and then the rainwater is reversely flushed into the space formed by the above-mentioned filter plate 6, the first baffle 62 and the water receiving box 3 through the filter plate 6, thereby realizing back flushing of the filter plate 6 and further reducing blocking of the filter plate 6.

Subsequently, the water volume in the space surrounded by the filter plate 6, the first baffle 62, and the water receiving case 3 is suddenly reduced, and thus the water pressure acting on the water receiving case 3 is reduced, and the water receiving case 3 is raised and returned by the first spring 113. When the water receiving box 3 is reset to the first position, the first baffle 62 re-closes the first flow passage 35, and the rainwater is filtered again by the filter plate 6 and discharged outside through the first drain pipe 112. At the same time, the water pressure acting on the closure plate 2 is reduced, and the closure plate 2 is restored and reseats the water through-hole 51 by the action of the second spring 521.

From the above, the filter plate 6 filters rainwater, thereby avoiding dirt from blocking the first drain pipe 112 and realizing the smoothness of the first drain pipe 112. In addition, the filter plate 6 has the effect of self-cleaning, so that the blocking duration of the filter plate 6 is shorter, the duration of rainwater and sewage converging is shorter, and when the filter plate 6 finishes self-cleaning, rainwater and sewage continue to split, thereby avoiding a great amount of rainwater from rushing into a sewage treatment plant and reducing the burden of the sewage treatment plant.

Whereby during this period the space defined by the enclosing of the filter plate 6, the first baffle 62 and the water receiving box 3 is gradually reduced, and the rainwater in this space flows into the space between the first baffle 62 and the third baffle 7 through the first flow channel 35, whereby a temporary storage of rainwater is achieved, and the unfiltered rainwater is prevented from flowing back out of the water receiving box 3 and falling into the rainwater chamber 11, thereby contaminating the rainwater chamber 11 and the first drain pipe 112.

In addition, when rainwater flows into the space between the first baffle 62 and the third baffle 7, the first baffle 62 can be washed, and dirt on the first baffle 62 is reduced.

When the water receiving box 3 is in the second position, the third baffle 7 is turned downwards under the pressure of rainwater, the third baffle 7 pushes the blocking plate 2 to move downwards, and the blocking plate 2 opens the water through hole 51, so that the water through hole 51 is communicated with the first runner 35.

Specifically, the intelligent rain and sewage diverter valve further comprises guide plates 8 which are equal to the number of the cranks 4 and correspond to each other one by one, wherein the guide plates 8 are fixedly arranged on the corresponding cranks 4, specifically, two rotating rods 41 of the cranks 4 are fixedly connected with the corresponding guide plates 8. The two baffles 8 are symmetrical to each other in the first direction.

When the water box is in the first position, the included angle between the two cranks 4 is larger, so that the two guide plates 8 are separated, when the water receiving box 3 is in the second position, the included angle between the two cranks 4 is smaller, so that the two guide plates 8 are propped against and lapped, at the moment, the two guide plates 8 are arranged in a splayed shape, the two guide plates 8 realize the diversion and the diversion of rainwater, the diverted rainwater flows to the two second flow channels 37 respectively, the design is convenient for the rapid aggregation of the rainwater in the second flow channels 37, and the back flushing of the filter plate 6 is realized.

Specifically, the water receiving box 3 is provided with two top plates 9 located at the water receiving port 31, the two top plates 9 are symmetrical to each other in the left-right direction, one top plate 9 is located at the left side of the two filter plates 6 and fixedly connected with the left side wall of the water receiving box 3, and the other top plate 9 is located at the right side of the two filter plates 6 and fixedly connected with the right side wall of the water receiving box 3. The opposite plate surfaces of the two filter plates 6 are set as inner surfaces, and the opposite surfaces of the two filter plates 6 are set as outer surfaces.

In the first position of the water collection cassette 3, the top plate 9 is in contact with the outer surface of the adjacent filter plate 6, in other words, the left top plate 9 is in contact with the outer surface of the left filter plate 6, and the right top plate 9 is in contact with the outer surface of the right filter plate 6. The top plate 9 and the filter plate 6 block the communication between the second flow channel 37 and the water receiving opening 31, and when the water receiving box 3 receives rainwater, the rainwater can only fall into the filter cavity 351 through the water receiving opening 31, so that the rainwater is prevented from directly flowing into the rainwater cavity 11 through the second flow channel 37, and the pollution of the rainwater cavity 11 is avoided.

When the water receiving box 3 is in the second position, the top plate 9 is separated from the adjacent filter plates 6, so that the top plate 9 and the filter plates 6 are communicated with the second flow channel 37 and the water receiving port 31, rainwater can flow into the second flow channel 37 in a closed state, rapid accumulation of the rainwater is realized, and back flushing of the filter plates 6 is further realized.

Specifically, the top surface of the closure plate 2 is provided with four inclined planes 21 which are distributed at intervals in the circumferential direction, the side edges of adjacent inclined planes 21 are connected, the tops of the four inclined planes 21 are connected and form an apex, the top surface of the closure plate 2 is provided with two convex strips 22 which extend in the left-right direction, the convex strips 22 are spaced in the front-back direction, and the apex is positioned between the two convex strips 22.

When the water receiving box 3 is located at the second position, the third baffle 7 is pressed by the rainwater in the first flow channel 35 and turns downwards under the pressure of the rainwater, and meanwhile, the third baffle 7 abuts against the raised strips 22 and pushes the raised strips 22 to move downwards, and the raised strips 22 drive the blocking plate 2 to move downwards and open the water through hole 51.

The protruding strips 22 are used for abutting against the third baffle 7, so that the rotation of the third baffle 7 can act on the closure plate 2, in other words, the protruding strips 22 can make the third baffle 7 drive the closure plate 2 to move downwards. The plurality of inclined surfaces 21 serve to divert and guide rainwater and dirt, so that the rainwater and dirt of the first flow passage 35 can be quickly and orderly dropped into the sewage chamber 12.

When the filter plate 6 is blocked, rainwater in the filter cavity 351 of the water receiving box 3 is continuously accumulated, the water pressure acting on the water receiving box 3 is gradually increased, the water receiving box 3 gradually moves downwards under the action of the water pressure, and the second baffle 63 is driven by the filter plate 6 to slowly seal the second flow channel 37. When the water receiving box 3 is located at any position between the first position and the second position, the filter plate 6 drives the second baffle 63 to rotate by a proper angle, the second flow channel 37 opens a proper gap, and unfiltered rainwater easily flows into the rainwater cavity 11 from the second flow channel 37, so that the rainwater cavity 11 is polluted. In order to weaken this phenomenon, the present invention also provides embodiment 2, protecting the rain chamber 11.

As shown in fig. 7 and 8, in embodiment 2, on the basis of embodiment 1, the outer peripheral surface of the water receiving box 3 is provided with a clamping groove 39, the peripheral wall of the rainwater cavity 11 is provided with a clamping post 116, one end of the clamping post 116, which is away from the peripheral wall of the rainwater cavity 11, is hemispherical and is matched in the clamping groove 39, the outer peripheral surface of the water receiving box 3 is provided with an arc-shaped groove 391 extending vertically, the bottom end of the arc-shaped groove 391 is communicated with the clamping groove 39, and the arc-shaped groove 391 is matched with one end of the clamping post 116, which is away from the peripheral wall of the rainwater cavity 11. It will be appreciated that the arcuate slot 391 has a cross-sectional shape that is arcuate and that is sized to conform to the end of the clip 116 that faces away from the perimeter wall of the rainwater chamber 11, thereby achieving a matching effect of the arcuate slot 391 and the end of the clip 116 that faces away from the perimeter wall of the rainwater chamber 11.

When the filter plate 6 is clogged, rainwater in the filter cavity 351 of the water receiving case 3 is continuously accumulated, and the water pressure acting on the water receiving case 3 is gradually increased, however, at this time, the water receiving case 3 is locked by the locking posts 116 due to the engagement of the locking grooves 39 and the locking posts 116. When the water pressure is large enough and breaks through the limit value of the clamping column 116 to the water box 3, the water box 3 moves downwards and drives the clamping groove 39 and the clamping column 116 to be separated, and the clamping column 116 slides into the arc-shaped groove 391 and slides in the arc-shaped groove 391.

The clip 116 is designed to provide an initial limit for the downward movement of the water receiving box 3, so as to prevent the water receiving box 3 from moving downward when the water pressure is low, and further to enable the second flow channel 37 to be in an open state. When the catching groove 39 and the catching post 116 are disengaged, the water receiving box 3 is quickly slid from the first position to the second position by the water pressure acting on the water receiving box 3 because the water pressure is sufficiently large, thereby reducing the amount of rainwater passing through the second flow path 37 and thus reducing the pollution of the rainwater chamber 11.

Wherein, the two clamping grooves 39 are spaced in the left-right direction, the number of the arc grooves 391 and the number of the clamping grooves 39 are equal and correspond to each other one by one, the arc grooves 391 are communicated with the corresponding clamping grooves 39, the number of the clamping columns 116 and the number of the clamping grooves 39 are equal and correspond to each other one by one, and the clamping columns 116 are matched in the corresponding clamping grooves 39. This design increases the reliability of the post 116 and slot 39 in use.

It should be noted that, the bottom surface of the arc-shaped slot 391 is provided with a hemispherical groove 3911, the diameter of the groove 3911 is smaller than the diameter of one end of the clamping post 116, which is away from the peripheral wall of the rainwater cavity 11, when the water receiving box 3 is in the second position, the clamping post 116 slides to the position of the groove 3911 and is clamped in the groove 3911, and at this time, the groove 3911 realizes a small amount of limiting on the clamping post 116, so that the stability of the water receiving box 3 is increased.

It can be appreciated that the material of the clamping post 116 is rubber with proper hardness and elasticity, so that the clamping post 116 and the clamping groove 39 are conveniently separated, and the clamping post 116 and the groove 3911 are conveniently clamped.

The first drain pipe 112 is provided with a first flowmeter and a first electrically operated flow regulator.
