Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage pipeline technology, and in particular to a drainage pipeline for urban planning. Background Technology
[0002] Municipal drainage pipes refer to rainwater and sewage pipes under municipal roads, commonly known as sewer pipes. In engineering, they are usually called municipal drainage pipes and are an important support for the development of urban infrastructure.
[0003] The high proportion of paved surfaces in cities reduces rainwater infiltration capacity. Therefore, drainage pipes are needed to quickly collect and transport rainwater to rivers or treatment facilities to prevent road flooding, traffic paralysis, building foundation damage, and even casualties caused by short-term heavy rainfall. However, traditional urban drainage pipes lack diversion designs, creating eddies at intersections that exacerbate local siltation, increasing siltation resistance, reducing water flow velocity, and further leading to a vicious cycle of siltation. Ultimately, this results in complete pipe blockage, and the long-term retention of silt leads to anaerobic fermentation, releasing toxic gases such as hydrogen sulfide and methane, corroding pipe wall materials, and shortening pipe lifespan.

[0024] To make the above-mentioned objectives, features and advantages 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.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0027] Example 1:
[0028] Reference Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides an urban planning drainage pipe, including a drainage pipe body 1, and a diversion component 2 is provided on the inner wall of the drainage pipe body 1.
[0029] The main drainage pipe 1 serves as the primary drainage channel, carrying and transporting urban rainwater and sewage.
[0030] The diversion assembly 2 includes a spiral guide plate 201 fixedly connected to the inner wall of the drain pipe body 1. A guide cylinder 202 is fixedly connected to the inner wall of the spiral guide plate 201. A diversion cover 203 is fixedly connected to the top of the guide cylinder 202. A filter cover 204 is fixedly connected to the outer side of the guide cylinder 202. The outer side of the filter cover 204 is fixedly connected to the inside of the drain pipe body 1. A mud guide box 205 is fixedly connected to the bottom of the filter cover 204.
[0031] The spiral guide plate 201 guides the water flow to generate a spiral motion, enhancing its self-cleaning ability. Moreover, the spiral structure creates a rotating flow field within the pipe, using the generated vortex to suspend sediment and reduce blockage in the main channel. The guide cylinder 202, as the core structure of the diversion component 2, connects the spiral guide plate 201 and the filter cover 204, evenly discharging the water flow into the interior of the drain pipe body 1, thus improving filtration efficiency. The diversion cover 203, through its umbrella-shaped design, diverts the water flow, increasing the contact area between the diverted water flow and the filter cover 204, making it easier to intercept impurities. This interception of impurities in the water prevents blockage of the drain pipe body 1. The impact force brought by the water flow guided by the spiral guide plate 201 carries the intercepted impurities into the opening 3 and into the mud guide box 205. The mud guide box 205 is used to guide the sediment intercepted by the filter cover 204 into the mud collection box 16.
[0032] The inner wall of the filter cover 204 has an opening 3, and the position of the opening 3 corresponds to the position of the mud guide box 205.
[0033] The opening 3 allows the silt filtered by the filter cover 204 to flow into the mud guide box 205, and the shape of the opening 3 is consistent with the size of the mud guide box 205.
[0034] Example 2:
[0035] This is the second embodiment of the present invention, which is based on the previous embodiment.
[0036] Specifically, the inner wall of the filter cover 204 has an opening 3, and the position of the opening 3 corresponds to the position of the mud guide box 205.
[0037] The opening 3 allows the silt filtered by the filter cover 204 to flow into the mud guide box 205, and the shape of the opening 3 is consistent with the size of the mud guide box 205.
[0038] Specifically, the inner wall of the drain pipe body 1 is connected to the first branch pipe 4 and the second branch pipe 5 respectively, and the first branch pipe 4 and the second branch pipe 5 are distributed in a cross shape.
[0039] The first diversion pipe 4 and the second diversion pipe 5 are arranged in a cross shape to achieve multi-directional drainage and improve drainage capacity.
[0040] Specifically, a first connecting flange 6 is fixedly connected to the outer side of both the first diversion pipe 4 and the second diversion pipe 5, and a first sealing gasket 7 is fixedly connected to the outer side of the first connecting flange 6.
[0041] The first connecting flange 6 and the first sealing gasket 7 ensure the sealing of the connection between the first branch pipe 4 and the second branch pipe 5 to prevent leakage.
[0042] Specifically, an expansion pipe 8 is connected to the outer side of the drain pipe body 1, and a guide groove 9 is provided on the inner wall of the expansion pipe 8.
[0043] The expansion pipe 8 extends the coverage of the drainage pipe body 1 and optimizes the water flow path. The guide channel 9 reduces water flow resistance and improves drainage efficiency through its streamlined design.
[0044] Specifically, a pipe cover 10 is fixedly connected to the inner wall of the drain pipe body 1, and the inner wall of the pipe cover 10 is provided with several grid holes.
[0045] The pipe cover 10 intercepts larger impurities, and the diameter of the grid holes in the pipe cover 10 is 10-20mm.
[0046] Example 3:
[0047] This is the third embodiment of the present invention, which is based on the first two embodiments.
[0048] Specifically, a pressure cylinder 11 is fixedly connected to the top of the drain pipe body 1. The pressure cylinder 11 has an annular pressure plate structure and presses on the top of the connection between the pipe cover 10 and the drain pipe body 1.
[0049] The pressure cylinder 11 presses the pipe cap 10 with an annular structure, and works with the second connecting flange 12 and the second sealing gasket 13 to ensure a stable connection.
[0050] Specifically, a second connecting flange 12 is fixedly connected to the top of the pressure cylinder 11, and a second sealing gasket 13 is fixedly connected to the outside of the second connecting flange 12.
[0051] The second connecting flange 12 is used to connect the drain pipe body 1 to the external pipe. The second sealing gasket 13 cooperates with the second connecting flange 12 to ensure sealing and prevent leakage.
[0052] Specifically, a mud-blocking plate 14 is fixedly connected to the bottom of the mud guide box 205. The inner wall of the mud-blocking plate 14 is provided with filter holes 15, and the outer side of the mud-blocking plate 14 is fixedly connected to the inner wall of the drain pipe body 1.
[0053] The mud baffle 14 and filter holes 15 perform secondary filtration of mud and sand to prevent impurities from entering the drain pipe body 1 and further trap fine particles. They are fixedly connected to the inner wall of the drain pipe body 1 to prevent mud and sand introduced into the mud collection box 16 from leaking into the drain pipe body 1. It should be noted that, according to industry standards, the diameter of the filter holes 15 and the filter cover 204 of the municipal drain pipe body 1 should be 2-5mm. This technology is common knowledge to those in the field and will not be elaborated on here.
[0054] Specifically, the inner wall of the drain pipe body 1 is connected to a mud collection box 16, and the outer side of the mud collection box 16 is fixedly connected to a cover 17 by bolts.
[0055] The mud collection box 16 collects and facilitates the cleaning of settled mud and sand. The cover 17 is fixed with bolts and is opened regularly for maintenance to ensure the long-term operation of the drain pipe body 1.
[0056] In use, the first diversion pipe 4 and the second diversion pipe 5 are connected to the corresponding positions of the drain pipe body 1 through the first connecting flange 6 and the second connecting flange 12. When drainage is required, the water flow is slowed down when it passes through the pipe cover 10. Then, after the diversion and preliminary filtration by the diversion cover 203, the diverted water flow is guided to the filter cover 204 for filtration through the spiral guide plate 201. The water flow is impacted by the guide plate 201 and the mud and sand are suspended. Then, it is guided into the mud guide box 205 through the opening 3 of the filter cover 204. The filtered mud and sand will follow the water flow through the mud guide box 205 and be guided into the mud collection box 16. The excess water flow with the mud and sand will be guided back to the drain pipe body 1 through the filter hole 15 of the mud baffle plate 14 and discharged through the expansion pipe 8 or by the first diversion pipe 4 and the second diversion pipe 5.
[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
