DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0030] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the vertical rainwater recycling system provided by the utility model includes:

[0032] A discard overflow module 1, the discard overflow module 1 comprises an initial rainwater discard device 2 and a rainwater gutter 3 arranged on the top of a building, the water inlet of the initial rainwater discard device 2 is communicated with the rainwater gutter 3 through a downpipe 4, the downpipe 4 is connected to a rainwater overflow pipe 5, the rainwater overflow pipe 5 is connected to a rainwater discard pipe 6, when rainwater enters the initial rainwater discard device 2 from the downpipe, since the initial rainwater will carry pollutants such as silt on the roof of the building, the initial rainwater discard device 2 can collect the pollutants and discharge them through other outlets to prevent the pollutants from affecting the water quality of the entire system, when the initial rainwater discard device 2 is full of water, the rainwater will be discharged to the rainwater discard pipe 6 through the rainwater overflow pipe 5 to prevent the rainwater from the downpipe from flowing back to the roof of the building due to the initial rainwater discard device 2 and being unable to be discharged;

[0033] A storage and regulation module 7, wherein the storage and regulation module 7 comprises a rainwater storage tank 8, wherein the inlet of the rainwater storage tank 8 is connected to the outlet of the initial rainwater discarding device 2 through a first water pipe 9. It can be understood that the initial rainwater discarding device 2 can collect and treat pollutants in the early rainwater, so the rainwater discharged from the outlet of the initial rainwater discarding device 2 is initially clean rainwater, and the rainwater storage tank 8 can be used for initial storage;

[0034] The conversion and water treatment module 10 includes a water treatment device 11. The water inlet of the water treatment device 11 is connected to the water outlet of the rainwater storage tank 8 through a second water pipe 12. It can be understood that the rainwater flowing into the water treatment device 11 is initially clean rainwater. After further treatment by the water treatment device 11, the initially clean rainwater is obtained as relatively clean rainwater. The relatively clean rainwater is not water of drinking standard, but can be used for greening water and indoor floor cleaning water.

[0035] The recycling module 13 comprises a clean water storage tank 14, the water inlet of the clean water storage tank 14 is connected with the water outlet of the water treatment device 11 through a third water pipe 15, and a water tank overflow port 16 is provided on the clean water storage tank 14, and the water tank overflow port 16 is connected with the rainwater discard flow pipe 6, and the end of the rainwater discard flow pipe 6 is connected with an outdoor rainwater inspection well. It can be understood that the rainwater treated by the water treatment device 11 can be stored as water for greening and ground cleaning. When the water in the clean water storage tank 14 is full, the rainwater can be discharged to the rainwater discard flow pipe 6 through the water tank overflow port 16, and finally the rainwater discard flow pipe 6 is discharged to the outdoor rainwater inspection well, thereby ensuring that the roof of the building can be drained smoothly.

[0036] For the utility model, the technical solution of the present application sequentially arranges the abandoned flow overflow module 1, the storage and regulation module 7, the conversion and water treatment module 10 and the recycling module 13 on the building from top to bottom, making full use of the water level difference formed by the height difference from the roof to the ground water point, and providing the hydraulic potential energy, without the need for a water pump. Compared with the prior art, the equipment of the present technical solution is all openly installed on the outer wall of a single body or in the overhead space, which is convenient for a large number of later maintenance, and rainwater collection does not pass through ground runoff, and has low requirements for water quality treatment equipment, which effectively reduces the construction and operation costs. The modular design is conducive to the industrial mass production of system products, and is conducive to the widespread promotion of rainwater reuse technology, which can produce actual water-saving and emission reduction environmental benefits. The modules can be flexibly combined according to the actual conditions of the project to meet the different needs of different scenarios, and can be used for peak regulation and emission reduction or collection and recycling, and can be freely converted.

[0037] In one embodiment, if Figure 2and Figure 4 As shown, the initial rainwater discarding device 2 includes an initial rainwater storage tank 17, and the initial rainwater storage tank 17 is provided with a accommodating chamber 18. The water inlet of the initial rainwater discarding device 2 is arranged at the top of the initial rainwater storage tank 17, and the water inlet is provided with a water inlet pipe 19, one end of the water inlet pipe 19 extends to the bottom of the accommodating chamber 18, and the water outlet of the initial rainwater discarding device 2 is located at the upper part of one side of the initial rainwater storage tank 17, and the lower part of the other side of the initial rainwater storage tank 17 is provided with an emptying pipe 20, and the emptying pipe 20 is connected to the rainwater discarding pipe 6.

[0038] It can be understood that when rainwater enters the initial rainwater discharge device 2, the water inlet pipe 19 can slowly flow the rainwater into the bottom of the accommodating chamber 18, so as to avoid the sludge in the rainwater from expanding into the entire accommodating chamber 18 due to the direct impact of rainwater on the bottom of the accommodating chamber 18, causing the rainwater in the accommodating chamber 18 to be relatively turbid, thereby increasing the processing pressure of the water treatment device 11, resulting in unclean rainwater treatment, thereby affecting user use. When the sludge in the rainwater gradually sinks to the bottom of the accommodating chamber 18 driven by the water inlet pipe 19, after the early rainwater is drained, that is, the upper part of the accommodating chamber 18 is rainwater clarified liquid, and the amount of sludge carried by the rainwater is less, the rainwater in the accommodating chamber 18 is filled with rainwater, and finally flows into the water treatment device 11 through the second water pipe 12. The sludge and other pollutants can be discharged to the rainwater discharge pipe 6 through the drain pipe 20.

[0039] Furthermore, it also includes a condensation water pipe 21 connected to the cooling system of the building, and a plurality of condensation interfaces 22 are arranged on the condensation water pipe 21, and the condensation interfaces 22 are respectively connected to the water inlet of the rainwater storage tank 8 and the water inlet of the clean water storage tank 14. The pit cooling system can generate condensation water, such as air conditioning, and the generated condensation is relatively clean and can be directly used for storage in the rainwater storage tank 8 or the clean water storage tank 14.

[0040] Furthermore, if Figure 3 As shown, the second water pipe 12 is connected to the rainwater waste flow pipe 6 through the fourth water pipe 23, and a maintenance conversion valve 24 is provided on the second water pipe 12 and the fourth water pipe 23. When the clean water storage tank 14 needs to be repaired and cleaned, the maintenance conversion valve 24 can be used to change the flow direction of the water flow, temporarily providing a waterless environment for maintenance and cleaning work, facilitating the maintenance work of the staff, and avoiding the continuous inflow of water during the maintenance process to affect the progress of the work.

[0041] Specifically, there are at least two rainwater storage tanks 8. When there are two rainwater storage tanks 8, the two rainwater storage tanks 8 are connected in series on the same floor or are respectively arranged on adjacent floors, and the two rainwater storage tanks 8 are connected through the fourth water pipe 23. The number of rainwater storage tanks 8 and the placement of rainwater storage tanks 8 can be set according to the actual floors of the building.

[0042] Similarly, there are at least two clean water storage tanks 14. There are two clean water storage tanks 14, which are connected in series on the same floor and are respectively arranged on adjacent floors, and the two clean water storage tanks 14 are connected through a fifth water pipe. The number of clean water storage tanks 14 and the placement of clean water storage tanks 14 can be set according to the actual floors of the building.

[0043] Furthermore, the clean water storage tank 14 is provided with a delivery pipe 25 for indoor greening water or floor cleaning, and a faucet 26 is installed at the end of the delivery pipe 25. Rainwater can be received through the faucet 26 for greening water and floor cleaning water.

[0044] Preferably, the clean water storage tank 14 is provided with a municipal water supply port, and the municipal water supply port is connected to a municipal water supply pipe 27. That is, the excess water in the clean water storage tank 14 will flow to the municipal water supply pipe 27, and the municipal water supply pipe 27 can supplement a certain amount of water resources for community water use and save water resources. It should be noted that the municipal water supply pipe 27 here is used for road cleaning water and environmental greening water, and is not a citizen drinking water pipe.

[0045] To sum up, the vertical rainwater recovery system provided by the utility model includes a discarded overflow module, a storage and regulation module, a conversion and water treatment module and a recycling module, which fully utilizes the water level difference formed by the height difference from the roof to the ground water use point to provide hydraulic potential energy. No water pump is required, and the excess rainwater can be passed through the municipal water supply pipe to supplement a certain amount of water resources for community water use. Compared with the prior art, the equipment of this technical solution is openly installed on the outer wall of a single body or the overhead space, which is convenient for a large number of later maintenance, and the rainwater collection does not pass through the ground runoff, and the requirements for water quality treatment equipment are low, which effectively reduces the construction and operation costs, and adopts a modular design, which is conducive to the industrialized mass production of system products and the widespread promotion of rainwater reuse technology.

[0046] The embodiments of the utility model are described above in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the utility model, ordinary technicians in this field can also make many forms without departing from the scope of protection of the utility model and the claims, which all belong to the protection scope of the utility model.
