Description

Technical Field

[0001] This utility model relates to the field of municipal drainage facilities technology, specifically to a prefabricated combined rainwater inlet. Background Technology

[0002] In urban construction, storm drains, as a key component of municipal road drainage systems, bear the important responsibility of collecting rainwater from the road surface and transporting it to the main storm drain. Common storm drains are mainly divided into two types: horizontal grates and vertical grates. Horizontal grates have grates set horizontally, flush with the road surface, offering the advantage of a large drainage area and high water collection efficiency. However, in actual use, they are easily clogged by fallen leaves and other debris, leading to poor drainage. Vertical grates, on the other hand, are arranged along the roadside curb, perpendicular to the road surface. Although their drainage area is relatively smaller and their water collection efficiency is lower, making them prone to water accumulation during heavy rain, they are less susceptible to clogging by debris.

[0003] To improve the above situation, some prefabricated rainwater inlets have emerged, with some prefabricated combined rainwater inlets using precast concrete structures to replace on-site masonry. For example, Chinese patent document CN115341635A discloses a prefabricated combined rainwater inlet. In this inlet, the rainwater inlet chamber uses precast concrete instead of masonry, resulting in higher structural strength and effectively preventing subsidence. It also employs a combined rainwater grate, retaining the high water collection efficiency of flat grate inlets while allowing drainage through the vertical grate even when the flat grate is covered and blocked by fallen leaves and other debris, thus improving drainage safety.

[0004] However, the prefabricated combined rainwater inlets mentioned above still have the following limitations in actual construction and use: First, during construction, the relative installation positions of the vertical grates and the horizontal grates lack auxiliary positioning benchmarks. The complex on-site construction environment and lack of effective auxiliary positioning methods make it difficult to guarantee assembly quality, easily leading to problems such as loose connections and excessive gaps between components, which in turn affects the overall performance and service life of the rainwater inlets. Second, during use, the vertical grates in existing prefabricated combined rainwater inlets are usually placed above the horizontal grates, occupying part of the rainwater inlet's projected area on the horizontal plane. That is, the water flowing through the vertical grates also enters the box through the opening at the top of the rainwater inlet, affecting the overall water flow performance. Furthermore, the water flowing through the vertical grates enters the box in a straight drop, making it difficult to coordinate with the hanging basket installed in the box, thus affecting the filtration effect of the rainwater inlet. Summary of the Invention

[0005] Based on the above problems, the purpose of this utility model is to provide a rainwater inlet structure to reduce the difficulty of on-site installation of assembled rainwater inlets, improve assembly quality, and improve the overall water flow performance and filtration effect of rainwater inlets.

[0006] To achieve the above objectives, this utility model proposes a prefabricated combined rainwater inlet, including a box body, a vertical grate assembly, a flat grate assembly, and a load-bearing connection unit;

[0007] The top of the box is provided with a first water inlet, and the edge of the first water inlet is provided with a support for installing the flat grate assembly. The side wall of the box is provided with a second water inlet, which is located at the lower edge of the support.

[0008] The flat grate assembly is installed on the support platform, and the vertical grate assembly is arranged on one side of the second water inlet on the tank body;

[0009] The load-bearing connection unit is located at the bottom of the grate assembly. The load-bearing connection unit includes a support plate, which is inclined on one side of the second inlet to form a flow guide slope. A protrusion is provided on the top of the support plate. The load-bearing connection unit is configured to support the bottom of the grate assembly using the support plate and limit the installation position of the grate assembly using the protrusion. The flow guide slope guides the water flowing through the grate assembly to the second inlet and into the tank.

[0010] Preferably, the grate assembly includes a first grate and a fixing frame, with the fixing frame mounted on the support platform and the first grate embedded within the fixing frame.

[0011] Preferably, the grate assembly includes a second grate and a support. The second grate is mounted on the support, and the bottom of the support is provided with a groove. The support is configured to install the second grate vertically to the first grate, and the sidewalls of the groove are used to press against the edge of the fixing frame.

[0012] Preferably, the bottom of the support is provided with a slot that matches the protrusion.

[0013] Preferably, the load-bearing connection unit also includes a side plate, which is installed at the end of the support plate.

[0014] Preferably, a water outlet is provided on the side wall of the tank, and the water outlet is close to the bottom of the tank.

[0015] Preferably, the second grille is mounted on the support by fasteners.

[0016] Preferably, the inner wall of the housing is provided with a raised edge for installing the filter basket.

[0017] Compared with existing technologies, the prefabricated combined rainwater inlet provided by this utility model has the following substantial features and advancements: This prefabricated combined rainwater inlet, by setting up a load-bearing connection unit, utilizes the protrusion on the top of the support plate in the load-bearing connection unit to limit the installation position of the grate assembly, providing a clear positioning benchmark for the relative installation of the grate assembly and the flat grate assembly. This solves the problem of lacking auxiliary positioning methods in existing rainwater inlet construction, making assembly more precise, ensuring tight connections between components, reducing installation difficulty, improving assembly quality, and thus enhancing the overall performance of the rainwater inlet and extending its service life. In terms of functionality, the grate assembly is located on the side of the second inlet on the side wall of the tank, without occupying the horizontal projection area of ​​the top of the rainwater inlet, avoiding any impact on the overall water flow performance. Simultaneously, the guide slope of the load-bearing connection unit can guide the water flowing through the grate assembly to the second inlet and into the tank, making the water flow path into the tank more reasonable and easier to coordinate with the hanging basket installed in the tank, effectively improving the filtration effect of the rainwater inlet.

[0024] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] In view of the defects of existing prefabricated combined rainwater inlets in the construction and use process, this utility model proposes a prefabricated combined rainwater inlet, which aims to reduce the difficulty of on-site installation of prefabricated combined rainwater inlets, improve assembly quality, and improve the overall water flow performance and filtration effect of rainwater inlets.

[0026] This utility model proposes a prefabricated combined rainwater inlet. The protrusion on the top of the support plate in the load-bearing connection unit limits the installation position of the grate assembly, providing a clear positioning benchmark for the relative installation of the grate and flat grate assemblies. This solves the problem of lacking auxiliary positioning methods in existing rainwater inlet construction, reduces installation difficulty, improves assembly quality, and thus enhances the overall performance and extends the service life of the rainwater inlet. Simultaneously, by placing the grate assembly on the side wall of the housing near the second inlet, it does not occupy the horizontal projection area of ​​the top of the rainwater inlet, avoiding any impact on the overall water flow performance. Furthermore, the guide slope of the load-bearing connection unit guides the water flowing through the grate assembly to the second inlet and into the housing, making the water flow path into the housing more rational and easier to coordinate with the hanging basket installed in the housing, effectively improving the filtration effect of the rainwater inlet.

[0027] like Figure 1 As shown, a prefabricated combined rainwater inlet includes a housing 1, a vertical grate assembly 2, a horizontal grate assembly 3, and a load-bearing connection unit 4. Figure 2 As shown, a first water inlet 11 is provided on the top of the housing 1. A support 12 for installing the flat grate assembly 3 is provided along the edge of the first water inlet 11. A second water inlet 13 is provided on the side wall of the housing 1. The second water inlet 13 is located at the lower edge of the support 12. The flat grate assembly 3 is installed on the support 12. The vertical grate assembly 2 is arranged on one side of the second water inlet 13 on the housing 1.

[0028] like Figure 3 and Figure 4 As shown, the load-bearing connection unit 4 is arranged at the bottom of the grate assembly 2. The load-bearing connection unit 4 includes a support plate 41. The support plate 41 is arranged at an angle on one side of the second inlet 13, forming a flow guide slope 44. A protrusion 42 is provided on the top of the support plate 41. The load-bearing connection unit 4 is configured to support the bottom of the grate assembly 2 using the support plate 41, and to limit the installation position of the grate assembly 2 using the protrusion 42. The flow guide slope 44 guides the water flowing through the grate assembly 2 to the second inlet 13, and from the second inlet 13 enters the tank 1.

[0029] like Figure 2As shown, the grate assembly 3 includes a first grate 31 and a fixing frame 32. The fixing frame 32 is mounted on the support platform 12. The first grate 31 is embedded in the fixing frame 32. This makes the disassembly and installation of the first grate 31 more convenient. If the first grate 31 is damaged or blocked in the future, it can be quickly replaced and cleaned, effectively reducing maintenance costs and difficulties. At the same time, the fixing frame 32, mounted on the support platform 12, provides stable support for the first grate 31, enhancing the overall structural strength of the grate assembly 3, enabling it to better withstand external forces such as vehicle crushing and pedestrian trampling, ensuring the safety of the rainwater inlet.

[0030] For example, the first grid is embedded in the fixed frame 32, one end of the first grid is hinged to the fixed frame 32, and the first grid can rotate around the hinge axis to open from the side.

[0031] like Figure 2 As shown, the grate assembly 2 includes a second grate 21 and a support 22. The second grate 21 is mounted on the support 22. A groove 23 is provided at the bottom of the support 22. The support 22 is configured to mount the second grate 21 vertically to the first grate 31, and the sidewall of the groove 23 presses against the edge of the fixing frame 32.

[0032] The support 22 uses the sidewall of the groove 23 to press against the edge of the fixed frame 32, which can be tightly connected with the flat grate assembly 3 to form a stable overall structure, enhancing the ability of the rainwater inlet to resist external impact and deformation. Even under harsh conditions such as repeated vehicle running over it or heavy rain, it can maintain the relative position stability of each component, reducing the risk of component loosening or falling off.

[0033] Furthermore, the method of pressing the groove 23 against the edge of the fixed frame 32 effectively fills the gap between the vertical grate component 2 and the flat grate component 3, reducing the possibility of rainwater leakage to the outside of the structure, preventing problems such as foundation settlement and road damage caused by rainwater leakage, and improving the durability of the rainwater inlet and the surrounding environment.

[0034] For example, such as Figure 3 As shown, the second grille 21 is mounted on the support 22 using fasteners. This fastener connection method facilitates quick disassembly of the second grille 21. When debris accumulates on the grille surface or internal damage occurs, workers can easily loosen the fasteners, remove the grille for cleaning or replacement, significantly improving maintenance efficiency and reducing labor costs.

[0035] like Figure 4As shown, the bottom of the support 22 is provided with a slot that matches the protrusion 42. Thus, the tight fit between the slot and the protrusion 42 provides a clear and stable positioning reference for the installation of the grate assembly 2, which can quickly and accurately determine the installation position of the grate assembly 2, greatly reducing the time spent on repeated adjustments during construction and improving installation efficiency; at the same time, it avoids problems such as loose component connections caused by installation deviations, thus ensuring assembly quality from the source.

[0036] In addition, the slot and the protrusion 42 fit together, which effectively restricts the horizontal displacement of the grate assembly 2, enhances the connection strength between the grate assembly 2 and the load-bearing connection unit 4, and enables the entire rainwater inlet structure to remain stable when subjected to external forces such as vehicle loads and water flow impacts, reducing the risk of component loosening and falling off, and extending the service life of the rainwater inlet.

[0037] like Figure 2 As shown, the load-bearing connection unit 4 also includes a side plate 43. The side plate 43 is installed at the end of the support plate 41. Thus, on the one hand, the side plate 43 and the support plate 41 form a stable three-dimensional support structure, which significantly enhances the overall rigidity of the load-bearing connection unit 4, effectively disperses the load transmitted by the grate assembly 2, and reduces the risk of deformation of the support plate 41; on the other hand, the side plate 43 can also effectively constrain the water flow path, and work in conjunction with the guide slope 44 to prevent water from overflowing or splashing, and guide the rainwater flowing through the grate assembly 2 to enter the housing 1 more smoothly from the second inlet 13.

[0038] like Figure 5 As shown, a water outlet 14 is provided on the side wall of the tank 1, and the water outlet 14 is close to the bottom of the tank 1. The water outlet 14 is used to connect to the drainage pipe. Multiple water outlet 14 positions are reserved on the side wall of the tank 1 to facilitate the selection of appropriate reserved openings for drilling as needed during on-site construction.

[0039] like Figure 5 As shown, the inner wall of the housing 1 is provided with a raised edge 15 for installing the filter basket. The raised edge 15 provides a stable and clear installation position for the filter basket. Construction personnel do not need complicated measurement and adjustment. They can simply place the basket on the raised edge 15 to complete the initial installation, which greatly simplifies the installation process and improves construction efficiency. At the same time, the raised edge 15 can assist in positioning to ensure that the position of the basket is accurate after installation and avoid the filtration effect being affected by installation deviation.

[0040] When using the assembled combined rainwater inlet proposed in this embodiment of the utility model, each component adopts a modular design, such as the vertical grate component 2, the flat grate component 3, and the load-bearing connection unit 4, which are independently formed, small in size, easy to disassemble and stack, and can also be placed in the box 1, which can effectively save transportation space.

[0041] This utility model is not limited to the specific technical solutions described in the above embodiments. Besides the above embodiments, this utility model may have other implementation methods. For those skilled in the art, 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.
