Description

Technical Field

[0001] This utility model relates to the field of rainwater drainage technology, specifically to a sewage interception and diversion pipe. Background Technology

[0002] Drainage pipes, also known as water diversion pipes, are used to discharge sewage or transport clean water. Existing drainage pipes are single-function; a common drainage pipe is simply a hollow plastic tube. Several drainage pipes are then connected together using pipe joints to form a pipeline transportation system for transporting water and discharging rainwater.

[0003] In existing urban drainage networks, rainwater is typically discharged directly into the stormwater pipe network through drainage ditches. Drainage ditch devices use covers to intercept some foreign objects, preventing excessively large objects from being discharged into the stormwater pipe network with the rainwater, causing blockages and water accumulation, and affecting rainwater discharge.

[0004] Furthermore, drainage systems are often inadequate in greenbelts and landscaped areas, allowing rainwater to slowly seep into the ground. This inability to drain water promptly leads to waterlogging. Especially during hot weather combined with showers, rainwater evaporates before it can penetrate the ground, causing water shortages for vegetation and potentially hindering groundwater replenishment.

[0005] To channel rainwater into the underground soil, the current practice is to lay drainage pipes in green belts and landscaped areas to form a rainwater drainage network, thereby promptly draining rainwater into the underground soil. However, because green belts and landscaped areas have a lot of fallen leaves and debris, the drainage pipes are easily blocked, affecting rainwater drainage and infiltration. Utility Model Content

[0006] The technical problem solved by this utility model is to provide a sewage interception and diversion pipe with interception and filtration functions, replaceable filter element device, and easy maintenance.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A sewage interception and diversion pipe includes a diversion pipe and a filter element device inserted inside the diversion pipe;

[0009] The guide pipe includes a guide pipe shell, and the filter element is inserted into the inside of the guide pipe shell and supported and fixed on the top of the guide pipe shell for guiding and filtering rainwater and intercepting foreign objects.

[0010] The filter element device includes a filter element housing and several layers of filter components regularly arranged inside the filter element housing.

[0011] Furthermore, the filter element device also includes a filter element top cover and a filter element bottom cover fixed to the top and bottom of the filter element housing, respectively. The filter element top cover is regularly provided with several water inlet holes to facilitate the inflow of rainwater, and the filter element bottom cover is regularly provided with several water outlet holes to facilitate the outflow of rainwater.

[0012] Preferably, the filter element bottom cover and the filter element outer shell are fixed by threaded connection or by fasteners.

[0013] Furthermore, the bottom cover of the filter element is made of metal mesh and is locked and fixed to the bottom end of the filter element housing by steel wire or clamps.

[0014] Furthermore, the outer edge of the filter element top cover is regularly provided with a top cover ring edge, the outer diameter of which is larger than the outer diameter of the guide tube shell; the filter element top cover is supported at the top of the guide tube shell by the top cover ring edge.

[0015] Furthermore, the plurality of filter components include a first filter layer, a second filter layer, and a third filter layer, which together form a three-layer filter network.

[0016] Preferably, the first filter layer comprises several pebbles or glass pumice for intercepting and filtering foreign objects; the second filter layer uses biological filler for rainwater filtration; and the third filter layer uses ecological porous fiber cotton or active fiber cotton for further filtration of rainwater.

[0017] Furthermore, a bottom cover for the guide tube is regularly provided at the bottom end of the outer shell of the guide tube, and a number of drainage holes are regularly provided on the bottom cover of the guide tube.

[0018] Preferably, both the outer shell of the guide tube and the outer shell of the filter element are hollow round tubes.

[0019] The beneficial effects of this utility model are:

[0020] This utility model's intercepting and diverting pipe effectively intercepts and filters rainwater by inserting a filter cartridge inside the pipe. The filtered rainwater is then channeled through the pipe into a water storage material, where it is partially absorbed by the roots of vegetation and partially replenishes groundwater. Excess rainwater is discharged through the underground pipe network.

[0021] Meanwhile, by filtering rainwater through the filter cartridge, harmful substances in the rainwater are absorbed and filtered out, reducing damage to vegetation and avoiding impact on the ecological environment. It also prevents harmful substances from seeping into the ground and affecting groundwater quality. The filter cartridge in this invention can be easily removed from the guide pipe for quick replacement. Alternatively, after removing the filter cartridge from the guide pipe, it facilitates the replacement and cleaning of the various filter components inside the cartridge, thereby significantly reducing operating costs.

[0032] To make the above-mentioned contents, objectives, and beneficial effects of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0033] It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] like Figure 1-4 As shown, this utility model provides a wastewater interception and diversion pipe, including a diversion pipe 1 and a filter element device 2 inserted and disposed inside the diversion pipe 1. The diversion pipe 1 includes a diversion pipe outer shell 11, which is a hollow circular tube. The filter element device 2 includes a filter element outer shell 21, a filter element top cover 22, a filter element bottom cover 23, and several layers of filter components regularly arranged inside the filter element outer shell 21. The filter element outer shell 21 is also a hollow circular tube. The filter element top cover 22 and the filter element bottom cover 23 are regularly arranged at the top and bottom ends of the filter element outer shell 21, respectively, encapsulating the several layers of filter components inside the filter element outer shell 21. The filter element device 2 is inserted and disposed inside the diversion pipe outer shell 11 and supported and fixed to the top of the diversion pipe outer shell 11, for guiding rainwater, filtering, and intercepting foreign objects.

[0035] Furthermore, such as Figure 4 As shown, the filter element top cover 22 covers the top of the filter element housing 21. At the center of the filter element top cover 22, within the hollow portion of the filter element housing 21, several water inlet holes 2201 or water inlet grilles are regularly arranged. These water inlet holes 2201 initially intercept rainwater, preventing larger debris such as leaves and tree trunks from flowing into the filter element housing 21 along with the rainwater. Rainwater flows into the interior of the filter element housing 21 through the water inlet holes 2201, and after further interception and filtration by several layers of filter components, flows out of the filter element device 2 from the filter element bottom cover 23. The rainwater filtered by the filter element device 2 flows into the guide pipe housing 11, and is then discharged into the ground through the guide pipe housing 11.

[0036] Furthermore, such as Figure 3 and Figure 4 As shown, in one embodiment, the plurality of filter components include a first filter layer 24, a second filter layer 25 and a third filter layer 26, which together form a three-layer filter network.

[0037] Preferably, in one embodiment, the first filter layer 24 is composed of several pebbles or glass pumice for intercepting and filtering foreign objects. The second filter layer 25 uses biological filler for filtering rainwater. The third filter layer 26 uses ecological porous fiber cotton or active fiber cotton for further filtering rainwater and adsorbing and filtering harmful substances in the rainwater.

[0038] This invention uses a three-layer filtration network inside the filter element device 2 to filter rainwater before it flows into the guide pipe 1 and is discharged. A portion of the filtered rainwater can be directly absorbed by the roots of vegetation, while another portion effectively replenishes groundwater. Furthermore, harmful substances in the filtered rainwater are absorbed, reducing damage to vegetation and the ecological environment, and preventing harmful substances from seeping into the ground and affecting groundwater quality. Simultaneously, the filter element device can be quickly removed and replaced, or its internal filtration layers can be cleaned and replaced, significantly reducing operating costs.

[0039] Furthermore, such as Figure 3 As shown, the first filter layer 24, the second filter layer 25 and the third filter layer 26 are installed inside the filter element housing 21. The bottom of the filter element housing 21 is covered by the filter element bottom cover 23, and the filter element bottom cover 23 supports the filter elements inside the filter element housing 21.

[0040] To facilitate the removal and replacement of multiple filter layers, preferably, the filter element bottom cover 23 is fixed to the filter element housing 21 by a threaded connection, thereby facilitating the installation and removal of the filter element bottom cover 23. Alternatively, in another embodiment, the filter element bottom cover 23 can be locked and fixed to the bottom end of the filter element housing 21 using screws or other fasteners. The specific material of the filter element bottom cover 23 is not limited; PVC or other plastic materials are preferred, but corrosion-resistant metal materials can also be used.

[0041] Alternatively, in another embodiment, the filter element bottom cover 23 can also be made of metal mesh and locked to the bottom of the filter element housing 21 by steel wire or clamps.

[0042] Furthermore, such as Figure 4 As shown, the outer edge of the filter element top cover 22 is regularly provided with a top cover ring edge 2202, and the outer diameter of the top cover ring edge 2202 is larger than the outer diameter of the guide tube shell 11. The filter element top cover 22 can support the filter element device 2 at the top of the guide tube 1 through the top cover ring edge 2202, which facilitates the removal and installation of the filter element device 2, thereby facilitating the replacement or cleaning of the several filter layers inside the filter element device 2.

[0043] Furthermore, the filter element top cover 22 is fixed to the top of the filter element housing 21. The filter element top cover 22 and the filter element housing 21 can be fixed by threaded connection, fastener locking, adhesive bonding, or thermosetting process.

[0044] like Figure 5The diagram illustrates an application of the sewage interception and diversion pipe of this invention. Several sewage interception and diversion pipes are vertically arranged and inserted into the soil 3 of green belts and landscaped areas. These pipes are then connected via pipe joints 4 and hollow circular pipes 5 to form a rainwater filtration and discharge network (underground pipe network). Rainwater is intercepted and filtered by the filter elements 2 within the interception and diversion pipes before flowing into the underground pipe network and being discharged into the underground soil. Part of the rainwater is absorbed by the roots of vegetation, while the remaining portion infiltrates into the groundwater, replenishing the city's groundwater. Alternatively, it can be discharged into the city's pipe network through the underground pipe network.

[0045] like Figure 6 The diagram shows another application of the sewage interception and diversion pipe of this utility model. A layer of porous, high-pressure-resistant water-retaining material 6 is laid in the underground soil, and then the sewage interception and diversion pipe of this application is installed in / on top of the water-retaining material 6. The sewage interception and diversion pipe of this application can quickly drain rainwater, preventing water accumulation. Simultaneously, after being filtered by the sewage interception and diversion pipe, the rainwater flows directly into the porous water-retaining material 6, where it is stored. Part of the water is directly absorbed by the roots of vegetation, and another part effectively replenishes groundwater. The water-retaining material 6 can be made of ecological porous fiber cotton. In practical use, a layer of coarse sand can be laid at the bottom of the ecological porous fiber cotton to effectively prevent fine soil particles from entering the ecological porous fiber cotton and affecting its water-retaining efficiency.

[0046] Furthermore, such as Figure 3 As shown, in one embodiment, a guide tube bottom cover 12 is regularly provided at the bottom end of the guide tube housing 11. The guide tube bottom cover 12 is threadedly engaged with the bottom end of the guide tube housing 11 and locked in place. The provision of the guide tube bottom cover 12 can prevent the filter element bottom cover 23 and several filter layers at the bottom end of the filter element device 2 from falling into the underground pipe network, and can also prevent the filter element device 2 from falling into the underground pipe network due to damage.

[0047] Furthermore, the bottom cover 12 of the guide pipe is regularly provided with several drainage holes 1201.

[0048] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
