Description

Technical Field

[0001] This utility model relates to the field of municipal road technology, and more specifically, to a drainage structure for road design. Background Technology

[0002] Drainage structures for road design are an important component of road engineering. Their main function is to remove surface water and groundwater that may stagnate within the roadbed area, preventing these waters from flowing into the roadbed and thus ensuring road stability and driving safety.

[0003] Patent CN217536561 U discloses a drainage structure for municipal roads. The rain grate prevents large solid debris from entering the frame. When small solid debris enters the frame through the rain grate, it is flushed by rainwater or by its own weight, converging along the inclined surface of the perforated plate into a waste collection box. The separated rainwater then flows downwards through the frame into the underground drainage pipes. Workers lift the waste collection box from its hidden slot using a handle, removing it from the frame under magnetic attraction and emptying the debris. However, in this municipal road drainage structure, the debris in the waste collection box can easily corrode the corresponding magnets, weakening or demagnetizing them, potentially making it difficult to lift the waste collection box. Furthermore, although the perforated plate is inclined, some debris that cannot be flushed into the waste collection box by rainwater may still remain, affecting the drainage effect.

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0047] like Figures 1-3 As shown, this embodiment provides a drainage structure for road design, including a cover plate 1, a water filter assembly 2 arranged below the cover plate 1, and a scraper assembly 3 arranged above the water filter assembly 2; collection assemblies 4 are also arranged on both sides of the water filter assembly 2 for collecting impurities scraped off by the scraper assembly 3.

[0048] In this embodiment, as Figure 3 and Figure 4 As shown, the cover plate 1 is provided with several drainage holes 11; the cover plate is also provided with several sliding grooves, referred to as the first sliding groove 12, the second sliding groove 13 and the third sliding groove 14. Rainwater flows downward through the cover plate 1, and the cover plate 1 can intercept most of the larger impurities.

[0049] In this embodiment, as Figures 5-6 As shown, the water filtration assembly is supported by two upright plates 5 at both ends. Specifically, the water filtration assembly 2 includes a first filter plate 21 and a second filter plate 22 arranged at an angle, with the first filter plate 21 and the second filter plate 22 arranged symmetrically; a filter trough 23 is arranged between the first filter plate 21 and the second filter plate 22; the first filter plate 21, the second filter plate 22 and the filter trough 23 are respectively provided with a number of filter holes 24 for filtering impurities that enter the cover plate in the water.

[0050] Furthermore, the water filter tank 23 is an upward-facing tank, and the bottom and sides of the water filter tank 23 are respectively provided with water filter holes 24, which facilitates the effective filtration of impurities in rainwater.

[0051] In this embodiment, as Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the scraper assembly 3 includes a first scraper 31 located above the first filter plate 21, a second scraper 32 located above the second filter plate 22, and a third scraper 33 located above the filter tank 23. The first scraper 31 abuts against the top of the first filter plate 21, the second scraper 32 abuts against the top of the second filter plate 22, and the third scraper 33 abuts against the top of the filter tank 23.

[0052] More specifically, the lower end face of the first scraper 31 is also provided with a first upper protrusion 311 and a first lower protrusion 312. Correspondingly, the first filter plate 21 is also provided with a first upper limit groove 211 and a first lower limit groove 212. The first upper protrusion 311 slides in the first upper limit groove 211, and the first lower protrusion 312 slides in the first lower limit groove 212 to limit the first scraper 31.

[0053] The lower end face of the second scraper 32 is also provided with a second upper protrusion 321 and a second lower protrusion 322. Correspondingly, the second filter plate 22 is also provided with a second upper limit groove 221 and a second lower limit groove 222. The second upper protrusion 321 slides in the second upper limit groove 221 and the second lower protrusion 322 slides in the second lower limit groove 222 to limit the second scraper 32.

[0054] The third scraper 33 is in the shape of a door, which is adapted to the inner contour of the water filter tank 23.

[0055] More specifically, in order to prevent impurities from moving in the opposite direction of the scraper's movement during the scraping process, buffer ridges are provided on each scraper. That is, the upper end face of the first scraper 31 is provided with a first buffer ridge 313, the upper end face of the second scraper 32 is provided with a second buffer ridge 323, and the upper end face of the third scraper 33 is provided with a third buffer ridge 331, which are used to block impurities.

[0056] To facilitate the scraping operation of the scraper assembly 3, a movable handle is provided above each scraper. Specifically, the slide groove of the cover plate 1 includes a first slide groove 12, a second slide groove 13, and a third slide groove 14, located above the first scraper 31, the second scraper 32, and the third scraper 33, respectively. A first movable handle 6 is connected to the middle of the first scraper 31, extending out of the first slide groove 12 and moving along it. A second movable handle 7 is connected to the middle of the second scraper 32, extending out of the second slide groove 13 and moving along it. A third movable handle 8 is connected to the middle of the third scraper 33, extending out of the third slide groove 14 and moving along it. By moving the corresponding handle above the cover plate 1, impurities on the corresponding first filter plate 21, second filter plate 22, or filter tank 23 can be scraped away, preventing the filter holes 24 from being covered by impurities and effectively ensuring the drainage effect of the filter assembly.

[0057] In this embodiment, as Figure 3 , Figure 9 and Figure 10As shown, the collection assembly 4 includes a collection tank 41 and a cover 42. The cover 42 is provided with perforations 421 for the lifting member 9 to extend into and pull up the cover 42. Specifically, one side of the collection tank 41 is adapted to the upper end face of the water filter assembly 2, so that impurities can be scraped into the collection tank by the scraper assembly.

[0058] The cover 42 covers the collection tank 41. The cover 42 is lifted by the lifting member 9. After the cover 42 is lifted, the impurities collected in the collection tank 41 are cleaned. Specifically, as shown... Figure 11 As shown, the lifting component 9 is I-shaped and includes a handle 91, a connecting rod 92, and a support rod 93 fixedly connected to it. After the support rod 93 extends into the through hole 421 of the cover 42, the lifting component 9 is rotated 90°. At this time, the support rod 93 is perpendicular to the through hole 421. Pulling the lifting component 9 will lift the cover 42. In this embodiment, the cover 42 is provided with two through holes 421, which facilitates a more stable lifting of the cover 42. In the lifting component 9, the end of the support rod 93 is also provided with a limiting block 94. Correspondingly, the lower end face of the cover 42 is provided with a groove 422. The limiting block 94 is embedded in the groove 422, which can temporarily fix the lifting component 9, thereby ensuring that the cover can be lifted stably. Using the lifting component 9 to lift the cover can not only avoid demagnetization and other phenomena in magnetic attraction, but also allow the cover 42 to be lifted smoothly for cleaning the collection tank 41. Furthermore, the separate design of the collection trough 41 and the cover 42 facilitates lifting and makes cleaning easier. In this embodiment, the I-shaped design of the lifting component 9 and the cooperation between the limiting block 94 and the groove 422 ensure greater stability of the cover 42 during lifting, avoiding cleaning difficulties caused by magnet failure. In daily use, the lifting component 9 of the drainage structure for road design provided in this embodiment is stored separately.

[0059] The drainage structure for road design provided in this embodiment filters rainwater sequentially through rainwater interception and preliminary filtration, followed by secondary filtration by the filter assembly 2. Impurities remaining on the filter assembly 2 are scraped into the collection assembly 4 by the scraper assembly 3. Lifting the cover 42 allows for the cleaning of impurities in the collection trough 41, thereby achieving efficient drainage and impurity interception and ensuring the continuity of the drainage structure. Its working principle is as follows:

[0060] First, rainwater flows into the drainage structure through the drainage holes 11 on the cover plate 1. The cover plate 1 intercepts most of the larger impurities, preventing them from entering the drainage system. The rainwater then passes through the water filtration assembly 2, specifically the first filter plate 21, the second filter plate 22, and the filter holes 24 on the filter tank 23, further filtering out small particulate impurities. The rainwater filtered by the water filtration assembly 2 continues to flow downwards into the connected drainage pipe, such as... Figure 1As shown. Impurities remaining on the upper surface of the water filter assembly 2 are scraped off by the scraper assembly 3 and collected in the collection assemblies 4 on both sides. The first scraper 31, the second scraper 32, and the third scraper 33 in the scraper assembly 3 move along the slide under the drive of the corresponding moving handle, and can scrape off impurities on the corresponding water filter plate and water filter tank 23. The scraped impurities are collected by the collection assembly 4. The cover 42 is lifted by the lifting member 9 to clean the impurities in the collection tank 41, ensuring the continuous effectiveness of the drainage structure.

[0061] In existing technologies, waste collection boxes are lifted using magnets, but impurities can easily corrode the magnets, weakening or demagnetizing them and affecting the smooth lifting of the waste collection box. This embodiment employs a mechanical connection between the lifting component 9 and the cover 42, secured by a limiting block 94 and a groove 422, avoiding magnet corrosion and improving structural reliability and service life. This embodiment also utilizes the active scraping design of the scraper assembly 3 to effectively clean impurities from the filter plates and filter tanks 23, preventing the filter holes 24 from becoming clogged and thus improving drainage efficiency.

[0062] In existing technologies, impurity removal relies on rainwater rinsing or the weight of the impurities themselves, resulting in limited cleaning effectiveness. This embodiment, through the cooperation of a scraper assembly and a collection assembly, achieves active cleaning and centralized collection of impurities, making the cleaning process more efficient and easier to operate.

[0063] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
