Description

Technical Field

[0001] This utility model belongs to the field of urban flood control equipment technology, and in particular relates to a debris interception device for rainwater wells used in urban flood control. Background Technology

[0002] Conventional storm drains primarily rely on internal filtration channels to intercept debris, providing some filtering and clogging protection during light rainfall. However, during heavy rains, large amounts of debris, such as fallen leaves and branches from greenbelts, are washed away and flow into the storm drains. Because conventional storm drain covers are horizontally positioned, debris easily and quickly covers the drain opening, severely impacting stormwater drainage. Furthermore, municipal personnel are limited, and with numerous storm drains requiring inspection, it's impossible to maintain long-term monitoring and timely manual drainage after cleaning, placing significant pressure on urban flood control. To address these issues, this application provides a debris interception device for storm drains used in urban flood control. Utility Model Content

[0003] The purpose of this utility model is to provide a debris interception device for urban flood control rainwater wells. Through a multi-stage interception structure and a convenient snap-fit ​​design, it solves the problems of existing rainwater wells being easily clogged by debris during heavy rain, inconvenient installation and maintenance, and drainage safety hazards.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a debris interception device for rainwater wells used in urban flood control, comprising a conical interception cover and four snap-fit ​​positioning devices; the conical interception cover comprises a cone-shaped cover with openings at the top and bottom, and a cone shape that is smaller at the top and larger at the bottom; the outer wall of the cone cover has a plurality of filter holes; a first rectangular frame is fixed to the upper end of the cone cover; a second rectangular frame is fixed to the lower end of the first rectangular frame; a pair of L-shaped plates are symmetrically fixed between opposite inner walls of the first rectangular frame; the horizontal plate of the L-shaped plate has a row of U-shaped slots that cooperate with the snap-fit ​​positioning devices.

[0006] As a preferred technical solution of this utility model, the outer wall of the conical cover is fixed with a number of first intercepting rods arranged along its slope.

[0007] As a preferred embodiment of this utility model, the snap-fit ​​positioning device includes a cylindrical rod that mates with the U-shaped groove, a spring sleeved on the cylindrical rod, and a positioning seat that snaps into the L-shaped plate; a handle is provided at the upper end of the cylindrical rod; a locking plate is fixed at the lower end of the cylindrical rod; a limiting ring plate is fixed to the outer wall of the cylindrical rod; and the spring is placed between the limiting ring plate and the positioning seat.

[0008] As a preferred embodiment of this utility model, the positioning bracket includes a circular annular washer slidably mounted on the cylindrical rod and a U-shaped buckle plate fastened to the L-shaped plate upright; one end of the U-shaped buckle plate is fixed to the circular annular washer.

Detailed Implementation

[0027] 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 scope of protection of the present utility model. Specific Implementation Example 1:

[0029] Please see Figure 1-2 and Figure 7 As shown, this utility model is a debris interception device for urban flood control rainwater wells. The device features an ingenious overall design, aiming to efficiently solve the problem of debris interception in urban rainwater wells during flood control. It mainly includes a conical interception cover 1 and four snap-fit ​​positioning devices 2. The conical interception cover 1 is one of the core interception components of this device, comprising a conical cover 11 with openings at the top and bottom, and a shape that is smaller at the top and larger at the bottom. This conical structure design has unique advantages, enabling the water flow to converge and increasing the contact area with debris when rainwater flows in. The outer wall of the conical cover 11 has several filter holes 12, which are evenly distributed and can initially filter small debris in the rainwater, allowing rainwater to pass smoothly while blocking debris. A first rectangular frame 13 is fixed to the upper end of the conical cover 11, providing a stable support structure for the upper part of the entire conical interception cover 1. A second rectangular frame 14 is fixed to the lower end of the first rectangular frame 13, and the two together enhance the overall strength of the conical interception cover 1. A pair of L-shaped plates 15 are symmetrically fixed between opposite inner walls of the first rectangular frame 13. A row of U-shaped slots 16 are provided on the horizontal portion of each L-shaped plate 15 to mate with the snap-fit ​​locator 2. These U-shaped slots 16 are designed for precise engagement with the snap-fit ​​locator 2, enabling rapid installation and fixation of the device.

[0030] The conical cover 11 has several first intercepting rods 17 fixed on its outer wall along its slope. These first intercepting rods 17 are evenly arranged along the slope of the conical cover 11. During heavy rain, they can effectively intercept larger debris such as branches and large fallen leaves that are washed in by the rainwater, preventing them from directly impacting the filter holes 12 or entering the rainwater well and causing blockage.

[0031] The snap-fit ​​locator 2 is a key component for device installation. It includes a cylindrical rod 21 that mates with the U-shaped slot 16, a spring 22 fitted onto the cylindrical rod 21, and a positioning bracket 26 that snaps into the L-shaped plate 15. A handle 23 is provided at the upper end of the cylindrical rod 21 for easy gripping and operation. A locking plate 24 is fixed at the lower end of the cylindrical rod 21. During installation, after the locking plate 24 passes through the gap in the manhole cover, the operator grips the handle 23 and rotates the cylindrical rod 21 to position the locking plate 24 under the manhole cover, thus limiting and securing it.

[0032] A limiting ring plate 25 is fixed to the outer wall of the cylindrical rod 21. A spring 22 is placed between the limiting ring plate 25 and the positioning bracket 26. The presence of the spring 22 enables the snap-fit ​​positioning device 2 to have a quick installation and positioning function. During installation, selecting the appropriate position of the U-shaped groove 16 on the L-shaped plate 15 can better adapt to rainwater well openings of different sizes, while ensuring the stability of the installation.

[0033] The positioning bracket 26 includes an annular washer 261 slidably mounted on the cylindrical rod 21 and a U-shaped buckle plate 262 fastened to the upright plate of the L-shaped plate 15. One end of the U-shaped buckle plate 262 is fixed to the annular washer 261. This structural design allows the positioning bracket 26 to be tightly engaged with the L-shaped plate 15, further enhancing the stability of the device installation.

[0034] Please see Figure 3-6 As shown, to adapt to drainage and filtration in waterlogged sections, an annular interception fence 3 is fixed to the upper end of the conical interception cover 1. The interception fence 3 intercepts high-level debris, further improving the effective height range of debris interception. The interception fence 3 includes multiple third rectangular frames 31. A ring of vertically arranged second interception rods 32 is fixed to the outer wall of the multiple third rectangular frames 31, and the lower ends of the second interception rods 32 are fixed to the second rectangular frames 14.

[0035] To make the location of the drainage well more visible, a reflective strip is affixed to the outer wall of the upper part of the barrier fence 3. During heavy rain or at night, the reflective strip reflects light, alerting pedestrians and vehicles to the location of the drainage well and preventing accidents.

[0036] A specific application of this embodiment is as follows: At the installation site of a storm drain on an urban road, the operator first moves the storm drain debris interception device for urban flood control to above the storm drain opening, aligning the opening of the conical interception cover 1 with the storm drain opening. Then, the operator holds the handle 23 of the snap-fit ​​locator 2 and inserts the cylindrical rod 21 into the U-shaped groove 16 on the horizontal part of the L-shaped plate 15. The U-shaped buckle 262 of the positioning bracket 26 is then fastened onto the vertical plate of the L-shaped plate 15. By pressing down the handle 23, the clamping plate 24 is driven through the gap of the storm drain cover. After holding the handle 23 and rotating it at a right angle, the clamping plate 24 is placed under the cover. After releasing the handle 23, the spring 22 extends. The remaining three snap-fit ​​locators 2 are installed in the same way. The four snap-fit ​​locators 2 and the conical interception cover 1 are stably and quickly positioned and installed on the storm drain cover, ensuring that the device is stably installed on the storm drain.

[0037] In daily use, when rainfall is light, rainwater smoothly enters the storm drain through the filter holes 12 on the outer wall of the conical cover 11 and the gaps in the intercepting fence 3, effectively trapping debris outside the device. During heavy rain, a large amount of debris flows into the storm drain with the rainwater. The first intercepting rod 17 on the outer wall of the conical cover 11 and the second intercepting rod 32 on the intercepting fence 3 work together to intercept debris in multiple stages, preventing it from quickly covering the drain opening and ensuring smooth drainage. Simultaneously, the reflective stickers on the intercepting fence 3 provide clear warnings to pedestrians and vehicles during heavy rain or at night, improving road safety. When cleaning or maintenance is required, the operator simply needs to press down on the handle 23 and rotate it in the opposite direction at a right angle to pull the locking locator 2 out of the storm drain cover, thus easily and quickly removing the device from the storm drain.
