Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of rainwater treatment technology, and more specifically, to a rainwater grate for municipal engineering. Background Technology

[0002] In municipal engineering, drainage systems are crucial infrastructure, and storm drains, as an important component of the drainage system, play a key role in collecting and discharging rainwater.

[0003] With the acceleration of urbanization, the area of ​​paved roads in cities is constantly increasing, such as asphalt roads. These roads generate a large amount of surface runoff during rainy weather. If rainwater cannot be drained in a timely and effective manner, it will lead to water accumulation on the road, affecting traffic safety and even causing urban flooding. This will seriously affect the normal operation of the city and the lives of residents. At the same time, long-term soaking in rainwater may also damage the road structure and shorten the service life of the road. For example, asphalt surface layers are prone to delamination under long-term soaking in rainwater, affecting the load-bearing capacity of the road.

[0004] Traditional storm drain grates have some limitations. For example, some storm drain grates have small opening ratios, making them prone to clogging and resulting in insufficient drainage. Under extreme weather conditions such as heavy rain, their water collection effect is poor, and a large amount of rainwater overflows, causing road flooding. Some storm drain grates also have unreasonable structural designs, such as poor side drainage or inappropriate spacing of the drainage ribs, which are easily blocked by fallen leaves and other debris, not only affecting drainage efficiency but also potentially causing sewer blockage. In addition, some storm drain grates experience more severe overflow phenomena when facing steep slopes or large gradients, such as urban underpasses, where a large amount of surface runoff overflows the storm drain grates during heavy rain, putting great pressure on urban drainage.

[0005] To address these issues, it is necessary to continuously improve the design and structure of storm drain grates, enhancing their drainage efficiency, anti-clogging capabilities, and adaptability to different working conditions. This will better meet the drainage needs of municipal engineering projects and ensure the safe and stable operation of cities. Therefore, developing a high-efficiency, stable, and easy-to-maintain storm drain grate for municipal engineering projects is of significant practical importance. Utility Model Content

[0006] To overcome the aforementioned deficiencies, the embodiments of this disclosure provide a storm drain grate for municipal engineering, which solves some limitations of traditional storm drain grates in the prior art.

Under extreme weather conditions such as heavy rain, their water collection effect is poor, and a large amount of rainwater overflows, causing road flooding. Some storm drain grates also have unreasonable structural designs, such as poor side drainage or inappropriate spacing of the drainage ribs, making them easy to be blocked by fallen leaves and other debris, which not only affects drainage efficiency but may also cause sewer blockage. In addition, some storm drain grates experience more severe overflow phenomena when facing steep slopes or large gradients, such as urban underpass tunnels, where a large amount of surface runoff overflows the storm drain grates during heavy rain, putting great pressure on urban drainage.

[0034] like Figures 1-4 As shown, a storm drain grate for municipal engineering according to this disclosure includes:

[0035] A pre-embedded frame 1 is provided with a collection port 2 at its upper end;

[0036] Lift the interception component 3, which is installed on the pre-embedded frame 1;

[0037] The pre-embedded component 4 is defined and is set inside the pre-embedded frame 1;

[0038] The lifting and intercepting component 3 includes a plug-in cavity 3-1, which is located on the inner wall of the pre-embedded frame 1. A lifting frame 3-2 is inserted into the plug-in cavity 3-1. A filter mesh 3-3 is provided on the side wall of the lifting frame 3-2. A limiting piece 3-4 is provided on the upper end face of the lifting frame 3-2. The limiting piece 3-4 is attached to the upper end face of the pre-embedded frame 1. A limiting strip 3-5 is provided on the inner bottom of the pre-embedded frame 1. A positioning frame 3-6 is provided inside the limiting strip 3-5. A rain grate 3-7 is provided on the positioning frame 3-6.

[0039] The pre-embedded component 4 includes an extension frame 4-1, which is located on the lower end face of the pre-embedded frame 1. The side wall of the extension frame 4-1 is provided with a pre-embedded strip 4-2. The inner side wall of the pre-embedded frame 1 is provided with a positioning slide 4-3. The outer side wall of the lifting frame 3-2 is provided with a positioning groove 4-4. The positioning slide 4-3 and the positioning groove 4-4 are slidably fitted together.

[0040] In some examples, it forms the basic support structure of the entire rain grate. The collection port 2 at its upper end collects rainwater, allowing it to enter the grate. The insertion cavity 3-1 is located on the inner wall of the embedded frame 1, providing space for the lifting frame 3-2 to be inserted, thus positioning and guiding it. The lifting frame 3-2 is inserted into the insertion cavity 3-1. The filter mesh 3-3 on its side wall filters debris from the rainwater, preventing larger solid waste from entering the drainage system. The limiting piece 3-4 on the upper surface is connected to the embedded frame. The upper surface of frame 1 is fitted to prevent the lifting frame 3-2 from sinking or shaking excessively, and to play a limiting role. The limiting strip 3-5 is set at the bottom inner side of the embedded frame 1 to fix the positioning frame 3-6, providing support and limiting for the positioning frame 3-6. The positioning frame 3-6 is located inside the limiting strip 3-5 and is used to install the rain grate 3-7, which plays a role in positioning and fixing the rain grate 3-7. The rain grate 3-7 is a component that is in direct contact with rainwater, further intercepting debris in the rainwater, while allowing rainwater to flow into the drainage system through its gaps.

[0041] The extension frame 4-1 is set on the lower end face of the pre-embedded frame 1, which increases the burial depth of the rain grate in the ground and improves the overall stability. Multiple pre-embedded strips 4-2 are evenly distributed on the outer side wall of the extension frame 4-1 to better fix the rain grate below the ground and prevent it from moving or loosening during use. The positioning slide strip 4-3 and the positioning slide groove 4-4 are respectively set on the inner side wall of the pre-embedded frame 1 and the outer side wall of the lifting frame 3-2. The two are slidably embedded, so that the lifting frame 3-2 can move up and down smoothly in the pre-embedded frame 1, and at the same time play a guiding and limiting role to ensure the accurate position of the lifting frame 3-2.

[0042] like Figures 1-4 As shown, in this embodiment, a stepped groove 3-8 is provided on the inner side of the positioning frame 3-6, and the rain grate 3-7 is embedded in the interior of the stepped groove 3-8. A clearance groove 3-9 is provided inside the stepped groove 3-8, and the clearance groove 3-9 is located on opposite sides of the rain grate 3-7.

[0043] In some examples, the stepped groove 3-8 is located inside the positioning frame 3-6 for embedding the rain grate 3-7, providing an installation position for the rain grate 3-7, and enhancing the sealing effect by cooperating with the rain grate 3-7 to prevent rainwater from leaking out of the gap.

[0044] For example, such as Figure 2 As shown, there are several embedded strips 4-2, and multiple embedded strips 4-2 are evenly distributed on the outer side wall of the extension frame 4-1. The lower end face of the embedded strip 4-2 is provided with an auxiliary embedded arc surface.

[0045] In some examples, the auxiliary pre-embedded curved surface facilitates the guidance of the pre-embedded strip 4-2 into the ground during the installation process, reducing resistance.

[0046] For example, such as Figure 4 As shown, the rain grate 3-7 has lifting grooves 5 on its opposite side walls. The lifting grooves 5 and the clearance grooves 3-9 are positioned corresponding to each other. The lower end face edge of the rain grate 3-7 is provided with a fitting ring 6, which is sealed and fitted with the stepped groove 3-8.

[0047] In some examples, the clearance groove 3-9 is set inside the stepped groove 3-8, located on opposite sides of the rain grate 3-7, corresponding to the lifting groove 5 on the side walls of the rain grate 3-7. This allows workers to easily remove the rain grate 3-7 from the stepped groove 3-8 by lifting the groove 5 for cleaning or replacement. The fitting ring 6 is located at the lower edge of the rain grate 3-7 and is sealed to the stepped groove 3-8, further preventing rainwater leakage from the connection between the rain grate 3-7 and the stepped groove 3-8 and improving the sealing performance.

[0048] For example, such as Figure 2 As shown, a collection cover 7 is provided on the inner side wall of the pre-embedded frame 1, and a rain collection port 8 is provided on the lower end face of the collection cover 7.

[0049] In some examples, the collection cover 7 is set on the inner side wall of the pre-embedded frame 1, and the collection port 2 on its lower end face is used to collect rainwater after it has been filtered by the rainwater grate 3-7 and the filter mesh 3-3, and guide the rainwater to the drainage system.

[0050] For example, such as Figure 2 As shown, the filter mesh consists of 3-3 vertically arranged strip-shaped holes at equal intervals.

[0051] In some examples, the filter mesh 3-3 consists of vertically spaced strip-shaped holes arranged at equal intervals. This design can effectively intercept debris while ensuring sufficient surface area for rainwater to pass through.

[0052] For example, such as Figure 2 As shown, the depth of the insertion cavity 3-1 matches the height of the lifting frame 3-2, and the shape of the insertion cavity 3-1 matches that of the lifting frame 3-2.

[0053] In some examples, the insertion cavity 3-1 and the lifting frame 3-2 are matched in depth and shape to ensure that the lifting frame 3-2 can be tightly inserted into the insertion cavity 3-1, which not only ensures the stability of the lifting frame 3-2, but also facilitates its disassembly and maintenance when needed.

[0054] In use, the collection port 2 at the upper end of the pre-embedded frame 1 is directly exposed to the ground. When rainwater falls, the collection port 2 acts as an inlet to guide the rainwater into the rain grate. The shape and position design of the collection port 2 ensures that rainwater can flow smoothly and avoid water accumulation. The filter mesh 3-3 (vertical strip holes arranged at equal intervals) on the side wall of the lifting frame 3-2 first filters the rainwater: larger debris (such as leaves, plastic bags, etc.) is intercepted on the outside of the lifting frame 3-2 to prevent it from entering the drainage system. After passing through the filter mesh 3-3, the rainwater flows downward into the rain grate in the positioning frame 3-6. 3-7, the gaps in the rain grate 3-7 further intercept smaller debris while allowing rainwater to pass through. The lifting frame 3-2 can move up and down within the embedded frame 1 through the sliding engagement of the positioning slide 4-3 and the positioning slide 4-4 (if the height needs to be adjusted due to ground settlement or maintenance). The limiting piece 3-4 at the upper end of the lifting frame 3-2 fits against the upper surface of the embedded frame 1 to prevent the lifting frame 3-2 from sinking excessively. The limiting strip 3-5 at the bottom inner side of the embedded frame 1 fixes the position of the positioning frame 3-6 to ensure the height stability of the rain grate 3-7 and avoid a decrease in filtration effect due to shaking.

[0055] The extension frame 4-1 and the embedded strip 4-2 extend deep into the ground. The auxiliary embedded arc surfaces on the outer sides of multiple embedded strips 4-2 facilitate reducing resistance during installation. After installation, they are fixed by soil compression, enhancing the overall structure's pull-out resistance and stability, and preventing the rain grate from shifting during long-term use. The positioning slide strip 4-3 on the inner side of the embedded frame 1 cooperates with the positioning slide groove 4-4 of the lifting frame 3-2, ensuring smooth sliding of the lifting frame 3-2 while limiting its lateral displacement, ensuring accurate positioning of the filter components. The fitting ring 6 on the lower end face of the rain grate 3-7 seals against the stepped groove 3-8 of the positioning frame 3-6, preventing rainwater from leaking through the gap between the rain grate 3-7 and the positioning frame 3-6, ensuring that all rainwater flows into the drainage system through the filter mesh 3-3 and the rain grate 3-7. The shape and depth of frame 3-2 match those of insertion cavity 3-1, reducing gaps and further preventing debris or rainwater from leaking from the side. The lifting slots 5 on both sides of rain grate 3-7 correspond to the clearance slots 3-9 in stepped groove 3-8. Workers can easily lift rain grate 3-7 by inserting tools into the slots to clean up the intercepted debris. Lifting frame 3-2 can be removed as a whole from insertion cavity 3-1 for deep cleaning of filter mesh 3-3, or the height of lifting frame 3-2 can be adjusted when needed (such as lifting the grate after laying new asphalt on the ground). The collection cover 7 on the inner wall of the pre-embedded frame 1 guides the rainwater filtered by rain grate 3-7 to the rainwater collection port 8 at its lower end, ensuring that rainwater flows quickly into the drainage pipe below and avoids stagnation inside the grate.

[0056] The rainwater path is as follows: ground rainwater → pre-embedded frame 1 collection port 2 → lifting frame 3-2 filter mesh 3-3 (preliminary filtration) → positioning frame 3-6 rainwater grate 3-7 (secondary filtration) → collection cover 7 rainwater collection port 8 → drainage pipe. The components work together to achieve a continuous process of "collection-filtration-guidance" while ensuring the stability and maintainability of the system.

[0057] This rain grate achieves efficient debris interception and smooth drainage through "double-layer filtration of the lifting interception component 3 + stable fixing of the pre-embedded component 4 + sealing and maintainable design". It is also suitable for scenarios such as ground subsidence and maintenance needs in municipal engineering, combining practicality and durability.
