Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, in particular to a house vertical pipe diversion and transformation drainage system. Background Art

[0002] Most of the house risers in old residential communities in China are combined sewer pipes, which are manifested in two forms: 1. Domestic sewage or washing wastewater is mixed into the rainwater risers. The rainwater risers mixed with sewage are directly connected to the municipal rainwater pipe network. Sewage is directly discharged into the river through the rainwater pipe network system, causing water pollution; 2. Rainwater is mixed into the sewage risers. The sewage risers mixed with rainwater are directly connected to the municipal sewage pipe network, causing the sewage concentration entering the sewage treatment plant to be low, affecting the sewage treatment of the sewage treatment plant, and also increasing the treatment capacity of the sewage treatment plant.

[0003] Currently, there are two main solutions for the diversion transformation of the above-mentioned risers: 1. Seal the top of the existing riser to prevent rainwater from the roof from entering. After sealing, the existing riser is connected to the municipal sewage network as a sewage pipe, and then a new rainwater riser is connected to the municipal rainwater network to drain rainwater from the roof, thereby realizing rainwater diversion; 2. Set a riser separator at the bottom of the existing riser, connect one outlet of the riser separator to the municipal rainwater network, and the other outlet to the municipal sewage network. On sunny days, the outlet of the riser separator to the municipal rainwater network is closed and the outlet to the municipal sewage network is opened, and the sewage in the riser is diverted to the municipal sewage network; when it rains, the outlet of the riser separator to the municipal rainwater network is opened and the outlet to the municipal sewage network is closed, and the rainwater in the riser is discharged to the municipal rainwater network. However, although the first modification scheme mentioned above achieves absolute separation of sewage and rainwater, for combined sewers in some occasions, modification is more difficult and costly due to the high floors of buildings. The second modification scheme requires the installation of a riser separator at the bottom of each riser. If the number of risers is large, many riser separators will be required, so the modification cost is also relatively high. Utility Model Content

[0004] In view of this, the present invention proposes a house vertical pipe diversion and reconstruction drainage system to solve the technical problems of high construction cost and difficult construction in the existing vertical pipe diversion and reconstruction scheme.

[0005] In order to achieve the above technical purpose, the present invention adopts the following technical solutions:

[0006] A house vertical pipe diversion and modification drainage system includes a vertical pipe, an outdoor sewage pipe and an outdoor rainwater pipe. The vertical pipe is arranged along the height direction of the house. It is characterized in that it also includes a diversion device, which has a water inlet, a first water outlet, a second water outlet and a regulating component. The water inlet is connected to the pipeline before the outdoor rainwater pipe is connected to the municipal rainwater network or the pipeline before the outdoor sewage pipe is connected to the municipal sewage network. The regulating component is used to control the connection or closing of the water inlet and the first water outlet and to control the connection or closing of the water inlet and the second water outlet to achieve the diversion of rainwater and sewage.

[0007] In some embodiments, the water inlet is connected to the outdoor rainwater pipe upstream, the first water outlet is connected to the outdoor rainwater pipe downstream, the second water outlet is connected to the outdoor sewage pipe, and the riser is connected to the outdoor rainwater pipe and disconnected from the outdoor sewage pipe.

[0008] In some embodiments, the number of the diversion device is one, the number of the risers is multiple, and the multiple risers are all connected to the outdoor rainwater pipe and disconnected from the outdoor sewage pipe.

[0009] In some embodiments, the water inlet is connected to the outdoor sewage pipe upstream, the first water outlet is connected to the outdoor sewage pipe downstream, the second water outlet is connected to the outdoor rainwater pipe, and the riser is connected to the outdoor sewage pipe and disconnected from the outdoor rainwater pipe.

[0010] In some embodiments, the number of the diversion device is one, the number of the risers is multiple, and the multiple risers are all connected to the outdoor sewage pipe and cut off from the outdoor rainwater pipe.

[0011] In some embodiments, the diversion device is a flexible diversion well, and the regulating component is a flexible shut-off member.

[0012] In some embodiments, the diversion device is a trough-type diversion well, and the regulating component is a trough-type intercepting member.

[0013] In some embodiments, the diversion device is a weir-type diversion well, and the regulating component is a weir-type shut-off member.

[0014] In some embodiments, a rainwater collecting device is further included, and the rainwater collecting device is arranged on the top of the vertical pipe.

[0015] In some embodiments, a slag net is provided at the rainwater outlet of the rainwater collection device.

[0016] Compared with the prior art, the beneficial effects of the present invention mainly include:

[0017] The utility model provides a house riser diversion and reconstruction drainage system, which does not require new rainwater risers and a riser separator at the bottom of each riser. Instead, it is only necessary to install a diversion device on the pipeline before the outdoor rainwater pipe is connected to the municipal rainwater network or before the outdoor sewage pipe is connected to the municipal sewage network, so as to solve the rainwater and sewage diversion problems of all risers.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] There are two main solutions for the diversion transformation of house risers: the first solution is as follows: Figure 1 As shown in the figure, the top of the vertical pipe 1 is blocked to prevent rainwater from the roof from entering. The blocked vertical pipe 1 is only connected to the outdoor sewage pipe 2 as a sewage pipe, and then discharged into the municipal sewage network. The rainwater flows into the outdoor rainwater pipe 3 through the newly built rainwater vertical pipe 6 and is then discharged into the municipal rainwater network, thus realizing the separation of rainwater and sewage. Figure 2 As shown, a standpipe separator 5 is installed at the bottom of each standpipe 1. One outlet of the standpipe separator 5 is connected to the outdoor sewage pipe 2, and the other outlet is connected to the outdoor rainwater pipe 3, thereby achieving rainwater and sewage separation. However, both of the above-mentioned existing modification solutions have the problems of high cost and difficult construction, and therefore urgently need improvement.

[0026] In order to solve the technical problems existing in the above-mentioned existing diversion and modification schemes, the present invention proposes a house vertical pipe diversion and modification drainage system, which includes, in addition to a vertical pipe 1, an outdoor sewage pipe 2 and an outdoor rainwater pipe 3, a diversion device 4. The vertical pipe 1 is arranged along the height direction of the house, and the outdoor sewage pipe 2 and the outdoor rainwater pipe 3 are used to receive the mixed water flow discharged from the vertical pipe 1. The diversion device 4 has a water inlet, a first water outlet, a second water outlet and a regulating component. The water inlet is connected to the pipeline before the outdoor rainwater pipe 3 is connected to the municipal rainwater network or the pipeline before the outdoor sewage pipe 2 is connected to the municipal sewage network. The regulating component is used to control the connection or closing of the water inlet and the first water outlet and to control the connection or closing of the water inlet and the second water outlet to achieve rainwater and sewage diversion.

[0027] By adopting the diversion and reconstruction scheme for the house riser provided by the present invention, it is only necessary to set a diversion device 4 before the outdoor sewage pipe 2 is connected to the municipal sewage pipe network or before the outdoor rainwater pipe 3 is connected to the municipal rainwater pipe network, so that the mixed rainwater and sewage water discharged from all the risers 1 to the outdoor sewage pipe 2 or the outdoor rainwater pipe 3 can be diverted, and the diverted rainwater enters the municipal rainwater pipe network and the diverted sewage enters the municipal sewage pipe network, thereby realizing the diversion of rainwater and sewage. Therefore, compared with the two existing reconstruction schemes, the reconstruction scheme of the present invention does not require the construction of a new rainwater riser 6, nor does it require the installation of a riser separator 5 at the bottom of each riser 1, and has the advantages of low cost and easy construction; it can also solve the problem of sewage pipes in the vicinity of the house being mixed and connected to the rainwater pipe, solve the problem of non-point source pollution in old residential areas, and achieve better diversion effect.

[0028] In actual use, since the riser 1 of the existing residential housing is usually connected to the outdoor sewage pipe 2, a specific embodiment of the present utility model is as follows Figure 3 As shown, the diversion device 4 is arranged on the pipeline before the outdoor rainwater pipe 3 is connected to the municipal rainwater pipe network.

[0029] In this embodiment, the water inlet is connected to the outdoor rainwater pipe 3 upstream, the first water outlet is connected to the outdoor rainwater pipe 3 downstream, and the second water outlet is connected to the outdoor sewage pipe 2. At this time, the riser 1 is connected to the outdoor rainwater pipe 3 and cut off from the outdoor sewage pipe 2.

[0030] In this embodiment, there is only one diversion device 4, and the number of risers 1 can be one or more. All of the risers 1 are connected to the outdoor rainwater pipe 3 and disconnected from the outdoor sewage pipe 2. That is, in this embodiment, it is necessary to first cut off the bottom of all the risers 1 originally connected to the outdoor sewage pipe 2 and reconnect them to the nearby outdoor rainwater pipe 3; then, a diversion device 4 is installed on the pipeline before the outdoor rainwater pipe 3 is connected to the municipal rainwater network. The mixed rainwater and sewage water in all the risers 1 will converge into the outdoor rainwater pipe 3, and then the diversion of the diversion device 4 will send the rainwater to the downstream outdoor rainwater pipe 3, and then flow into the municipal rainwater network, while the sewage will be sent to the outdoor sewage pipe 2, and then flow into the municipal sewage network, thus achieving rainwater and sewage diversion.

[0031] If the rainwater and sewage are separated in a newly built house, the diversion device 4 can also be set in the pipeline connecting the outdoor sewage pipe 2 to the municipal sewage network. Figure 4 As shown, the diversion device 4 has a water inlet, a first water outlet and a second water outlet. The water inlet is connected to the outdoor sewage pipe 2 upstream, the first water outlet is connected to the outdoor sewage pipe 2 downstream, and the second water outlet is connected to the outdoor rainwater pipe 3. The riser 1 is connected to the outdoor sewage pipe 2 and cut off from the outdoor rainwater pipe 3.

[0032] In this embodiment, there is only one diverter device 4, and the number of standpipes 1 can be one or more. All of the standpipes 1 are connected to the outdoor sewage pipe 2 and disconnected from the outdoor rainwater pipe 3. That is, in this embodiment, the mixed rainwater and sewage flows in all standpipes 1 first converge into the outdoor sewage pipe 2, where they are then diverted by the diverter device 4, sending the sewage downstream to the outdoor sewage pipe 2 and then to the municipal sewage network, while the rainwater is sent to the outdoor rainwater pipe 3 and then to the municipal rainwater network, thus achieving rainwater and sewage diversion.

[0033] In the two aforementioned embodiments, the diverter device 4 can be any one of a flexible diverter well, a trough-type diverter well, and a weir-type diverter well; the control assembly can be any one of a flexible intercepting member, a trough-type intercepting member, and a weir-type intercepting member. That is, the control assembly is disposed within the well and connected to the well's water inlet, first water outlet, and second water outlet. It is understood that the flexible diverter, trough-type diverter, and weir-type diverter are patented technologies filed by the applicant of the present utility model prior to the present invention and are now fully disclosed. The structure and operating principles of these components are common knowledge in the art and will not be further elaborated upon here. For details, please refer to the “A diversion device with a flexible shut-off member” disclosed in the authorization announcement number CN215483389U and the pneumatic riser diverter with application number 202421302866.3, the “A diversion well with a semicircular groove horizontal grid interception device” disclosed in the authorization announcement number CN207633500U, and the “A diversion well constant flow system and method with a fixed weir” disclosed in the authorization announcement number CN107675783B.

[0034] The above two embodiments further include a rainwater collecting device, which is arranged on the top of the vertical pipe 1, and a slag net is also provided at the rainwater outlet of the rainwater collecting device.

[0035] In summary, the house vertical pipe diversion and renovation drainage system provided by the utility model only needs to set a diversion device 4 on the pipeline before the outdoor rainwater pipe 3 is connected to the municipal rainwater network or on the pipeline before the outdoor sewage pipe 2 is connected to the municipal sewage network to achieve rainwater and sewage diversion. Compared with the existing renovation plan, it has the advantages of low cost and low construction difficulty; and solves the problem of outdoor community sewage pipes being mistakenly connected to community rainwater pipes.

[0036] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
