[0064] Specifically, Fig.11As shown, the control devices 20 of the automatic switches 3 are electrically connected in series in sequence through the first line 26 according to the arrangement order of the corresponding water reservoirs 9.

[0065] When there is no water, except for the automatic switch 3 of the first water reservoir 9, the automatic switches 3 of all other water inlet branches 1001 are in a closed state; after the water is filled, wait for the first water reservoir 9 to complete the water storage, and then close the first automatic switch 3; after the first automatic switch 3 is closed, its control device 20 transmits a second electrical signal to the control device 20 of the second automatic switch 3 through the first line 26, and turns on the second automatic switch 3; then wait for the second water reservoir 9 to complete the water storage, and then close the second automatic switch 3; after the second automatic switch 3 is closed, its control device 20 transmits a second electrical signal to the control device 20 of the third automatic switch 3, and turns on the third automatic switch 3; then wait for the third water reservoir 9 to complete the water storage...

[0069] In other embodiments, the housing 21 may also be arranged in other directions, as long as its axis is perpendicular to the axis of the water inlet branch 1001, that is, as long as the free end of the telescopic rod can move radially along the water pipeline.

[0070] In this embodiment, the housing 21 is a hollow rectangular parallelepiped structure, the switch body is a baffle 18, and the baffle 18 is a hollow rectangular structure; the height and width of the baffle 18 are greater than the diameter of the water inlet branch 1001, and the thickness of the baffle 18 is adapted to the disconnection distance of the water inlet branch 1001, so that the baffle 18 can completely separate the disconnection distance. Specifically, the baffle 18 includes two first side plates, two second side plates and a bottom plate, the first side plate is vertically arranged with the second side plate, the outer surface of the first side plate is greater than the cross section of the water inlet branch 1001, and the distance between the two first side plates is adapted to the disconnection distance of the water inlet branch 1001; the second side plate is adapted to the inner side wall of the housing 21; correspondingly, the free end of the telescopic rod extends into the hollow rectangular structure of the baffle 18 and is fixedly connected to the bottom plate.

[0075] Furthermore, the main body of the water reservoir 9 includes an upper cover 5 and a water reservoir, the water reservoir is a cavity with an opening at one end, an inlet connected to the water inlet branch 1001 is provided on the water reservoir, and the upper cover 5 is adapted to the open end of the water reservoir; the water level detector 8 is installed on the lower surface of the upper cover 5; a water intake port 7 is provided at the center of the upper cover 5, and a sealing cover 6 is provided on the water intake port 7, and the water intake port 7 is a round hole. The water intake port 7 is used to extract water samples from the water reservoir 9.

[0076] Furthermore, the upper cover 5 is a sealing layer, and the water storage body and the upper cover 5 are both made of breathable and impermeable materials, which can prevent the stored water from leaking and reduce the chance of water corruption, and can perfectly store and collect rainwater. The breathable and impermeable material is concrete made of breathable and impermeable sand, and can also be other materials.

[0077] Furthermore, the water level detector 8 includes a first wire 22 and a second wire 23 which are arranged at intervals. When the water level detector 8 is not in contact with the water surface 24 in the water reservoir 9, the first wire 22 and the second wire 23 form a disconnected circuit; after the water level detector 8 is in contact with the water surface 24 in the water reservoir 9, the first wire 22 and the second wire 23 form a passage through the water surface 24, and the passage transmits the first electrical signal to the corresponding automatic switch 3.

[0078] Furthermore, the water storage tank 9 system also includes a sediment separator 10 and a sewage pipe 11.

[0079] The sediment separator 10 is installed on the water inlet branch 1001 and is located between the automatic switch 3 and the water reservoir 9. It is used to separate rainwater in the water inlet branch 1001 into clean water and sewage. The inlet of the sediment separator 10 corresponds to the automatic switch 3, and the outlet corresponds to the water reservoir 9.

[0080] The sewage pipe 11 is communicated with the sewage outlet of the sediment separator 10 .

[0081] Furthermore, the sediment separator 10 includes: an outer shell 101, a partition 13 and an annular filter screen 14. The outer shell 101 is a hollow cylindrical structure. The partition 13 is used to separate the outer shell 101 into an upper cavity and a lower cavity, and a through hole is provided at the center of the partition 13; the inlet of the sediment separator 10 is connected with the upper cavity. The annular filter screen 14 is fixed in the lower cavity, and a clean water cavity is formed between the outer periphery of the annular filter screen 14 and the inner wall of the outer shell 101; the outlet of the sediment separator 10 is connected with the clean water cavity; the upper part of the inner cavity of the annular filter screen 14 is connected with the through hole, and the lower part is connected with the sewage outlet.

[0082] Specifically, the inlet of the sediment separator 10 is arranged at the upper part of the side wall of the shell 101 ; the outlet is located at the lower part of the side wall of the shell 101 ; and the sewage outlet is located at the center of the bottom of the shell 101 .

[0083] Furthermore, a first sleeve 141 is fixedly provided at the upper end of the annular filter screen 14, and an annular first embedded section 17 is fixedly provided at the lower end; the first sleeve is installed on the partition 13 through the overlapping section 12, the overlapping section 12 includes an upward turning edge 121 and an annular second embedded section 122, the upward turning edge 121 is located above the partition 13, and the second embedded section 122 is inserted into the first sleeve 141 through the through hole; an annular fixed base 15 is fixedly provided on the annular bottom plate 16 of the outer shell 101, the first embedded section 17 is inserted into the fixed base 15, and the fixed base 15 is connected to the sewage outlet.

[0084] The sediment separator 10 is in a sealed state as a whole, which will not cause sewage to leak into the water storage tank 9, thereby reducing pollution.

[0085] In this embodiment, the overlapping section 12, the first casing 141, the annular filter screen 14, the first embedded section 17, and the fixed base 15 constitute a filtering device of the sediment separator 10. The filtering device has the advantages of good sealing effect and convenient insertion. Specifically, the filtering device is inserted into the through hole of the annular partition 13, and the overlapping section 12 is tightly connected to the partition 13 to form a sealed whole, so that rainwater can only enter the lower part through the central circular hole of the overlapping section 12, and the first embedded section 17 is connected to the fixed base 15 to form a fixed whole, and the sewage pipe is connected to the annular bottom plate 16 as a whole. The fixed base 15 is hollow inside, and sewage can enter the sewage pipe 11 through the fixed base 15; rainwater enters the upper cavity of the shell 21 through the inlet of the sediment separator 10. Since the water flow has a certain flow rate, it is easy to form a vortex when the water flow hits the inner wall of the shell 21. The water flow and the inner wall of the shell 21 generate centrifugal force. Under the blocking effect of the annular filter screen 14, the water mixed with sediment flows downward; the clear water flows through the annular filter screen 14 under the action of centrifugal force and flows into the clean water cavity.

[0086] In other embodiments, the filtering device is an annular filter screen 14 , the upper end of the annular filter screen 14 is fixedly connected to the partition plate 13 , and the lower end of the annular filter screen 14 is fixedly connected to the annular bottom plate 16 .

[0087] The present invention can store rainwater from different times in different water storage tanks 9 in chronological order, isolate the pollution in the rainwater in time sequence, and avoid the spread of pollution between the water storage tanks 9 and the cross-contamination of rainwater in different time periods. In addition, the sediment separator 10 of the present invention can separate large impurities such as mud and dirt from rainwater, and improve the cleanliness of the water entering the water storage tank 9; and the sediment separator 10 achieves the effect of rainwater separation with the simplest possible structure without providing additional power, and has strong practicality.

[0088] The use principle and use process of the present invention are:

[0089] The process of storing rainwater in the reservoir 9 is that the rainwater is transported to the reservoir 9 through the water inlet pipe 1, the automatic switch 3 is in the on state, and the ordinary switch 4 is in the off state; the rainwater flows through the sediment separator 10, and is separated into relatively clear water and sewage containing sediment by centrifugal action. The sewage is discharged into the urban sewage system through the sewage pipe 11, and the clean water enters the reservoir 9 through the water inlet branch 1001 connecting the sediment separator 10 and the reservoir 9; the automatic switch 3 is connected to the water level detector 8, and the water level detector 8 is essentially a disconnected passage. After the first guide and second wires 23 of the water level detector 8 come into contact with the water surface 24, the circuit is connected, and the passage transmits a first electrical signal to the control device 20 corresponding to the automatic switch 3, starts the driving device 19, and lowers the baffle 18 to disconnect the corresponding water inlet branch 1001.

[0090] When the water level in the first water storage tank 9 reaches the position of the water level detector 8, the circuit is connected, the automatic switch 3 is started, the connection between the water inlet pipe 1 and the first water storage tank 9 is closed, the sealing cover 6 is placed on the water inlet 7 of the upper cover body 5, the sealing cover 6 is completely closed, the water inlet 7 is sealed, the upper cover body 5 becomes a whole, and together with the automatic switch 3 and the common switch 4, the water storage tank 9 is completely sealed. Rainwater can enter the remaining water storage tanks 9.

[0091] To inspect the rainwater stored in the water reservoir 9, it is necessary to open the sealing cover 6, extract water samples from the water reservoir 9 through the water intake 7, and then analyze the extracted water samples to confirm the degree of contamination of the water reservoir 9.

[0092] The water reservoir 9 stores rainwater. After analysis confirms that the water quality stored in the water reservoir 9 is within an acceptable pollution level and can be discharged, the ordinary switch 4 is turned on to discharge the unpolluted rainwater into the urban drainage system or natural water body through the outlet pipe 2.

[0093] In summary, the present invention isolates and stores rainwater, thereby blocking the spread of pollution in rainwater to the greatest extent possible, reducing the pollution of water stored in sponge cities, realizing the functions of rainwater storage, filtration, purification, etc., and ensuring the cleanliness of urban water bodies.

[0094] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0095] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
