Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, specifically to a municipal rainwater infiltration device. Background Technology

[0002] Municipal stormwater infiltration systems are an important component of urban drainage systems. By collecting and utilizing rainwater resources, they effectively reduce the pressure on urban drainage systems and also contribute to improving the quality of the urban ecological environment. Infiltration wells are facilities used for rainwater infiltration to replenish groundwater, and they play a role in purifying rainwater and reducing peak flow rates.

[0003] Most existing infiltration devices do not have a structure to collect foreign objects during use. As a result, when the device is used in rainy weather, rainwater will carry small foreign objects such as stones directly into the inside of the sewer pipe, while heavier foreign objects such as stones will gradually accumulate inside the sewer pipe. Over time, this can easily lead to sewer pipe blockage and reduce the applicability of the device.

[0004] Meanwhile, most existing devices do not limit the position of the cover during use, but are held in place by their own weight. This method can easily cause the cover to shake after vehicles run over the device and the road surface for a long time, resulting in abnormal noises when vehicles run over it. Furthermore, the cover may detach from the device under greater force, reducing the safety of the device during use. Utility Model Content

[0021] 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.

[0022] Please see Figure 1-4As shown, a municipal rainwater infiltration device includes a mounting shell 1. A mounting groove 2 is formed on the top of the mounting shell 1. A cover 3 is slidably connected to the inner cavity of the mounting groove 2. The cover 3 is used to block foreign objects, preventing them from easily entering the interior of the mounting shell 1 and causing blockage of the sewer pipe. A seepage groove 4 is formed on the surface of the cover 3, allowing rainwater to enter the interior of the mounting shell 1 while larger foreign objects are blocked by the cover 3. A positioning mechanism 5 is installed on the surface of the cover 3, limiting its position and preventing it from easily shifting when not in use, effectively improving the stability of the cover 3 during use. A [missing information - likely a design feature] is formed at the bottom of the inner cavity of the mounting groove 2. The slot 6 has a slidable retaining ring 7 inside. The thickness of the retaining ring 7 is the same as the depth of the slot 6. The retaining ring 7 works in conjunction with the mounting groove 2, allowing it to embed into the slot 6. This prevents the bottom of the mounting groove 2 from being uneven due to the large size of the retaining ring 7. The retaining ring 7 also supports the inner wall of the mounting groove 2 and the cover 3, making the cover 3 more stable. A connecting plate 8 is fixedly connected to the inner cavity of the retaining ring 7. A connecting rod 9 is fixedly connected to the bottom of one side of the connecting plate 8. The other end of the connecting rod 9 is fixedly connected to a sludge collection shell 10. The sludge collection shell 10 filters rainwater entering the mounting shell 1 again, thereby reducing the amount of rainwater entering the mounting shell 1. The collection shell 10, with its conical cross-sectional shape, is designed to collect pebbles and other particulate matter, further reducing the likelihood of blockages in the sewer. It works in conjunction with the seepage trough 4, allowing rainwater entering from the seepage trough 4 to directly flow into the collection shell 10. The shape of the collection shell 10 guides and collects foreign objects, reducing rainwater residue inside. A filter screen 11 is fixedly connected to the bottom of the inner cavity of the collection shell 10, blocking foreign objects and separating them from rainwater, thus improving the device's applicability. Several drainage holes 12 are located above the inner cavity of the collection shell 10, all positioned within the collection shell 10. The filter screen 11 and the drain hole 12 are arranged in a ring at the center. Under this arrangement, the rainwater can be discharged directly from the drain hole 12 when there is heavy rain. The floating foreign objects can be blocked by the drain hole 12. With the cooperation of the filter screen 11 and the drain hole 12, heavier and lighter foreign objects can be effectively separated, which effectively improves the collection effect of the device. The surface of the connecting plate 8 is provided with a movable groove 13. The movable groove 13 is used in conjunction with the sludge collection shell 10. Under this arrangement, the movable groove 13 allows the staff to remove the sludge collection shell 10 with the help of auxiliary tools. It provides the staff with an effective point of force, making it more convenient for the staff to remove the sludge collection shell 10.

[0023] The positioning mechanism 5 includes a fixing groove 51 formed on the surface of the cover 3. The inner cavity of the fixing groove 51 is connected to a positioning groove 52. A positioning block 53 is fixedly connected to the inner cavity of the mounting groove 2. The surface of the positioning block 53 is slidably connected to the inner walls of the fixing groove 51 and the positioning groove 52. Under this action, when positioning the cover 3, the positioning block 53 can slide into the inside of the fixing groove 51. Then, the cover 3 is rotated to make the positioning block 53 slide into the inside of the positioning groove 52. Under the action of the weight of the cover 3 itself, the positioning block 53 can be completely embedded into the inside of the positioning groove 52, thereby limiting the cover 3 and preventing the cover 3 from easily shifting its position when it does not need to move, thus affecting its stability. It also reduces the shaking of the cover 3. The cross-sectional shape of the fixing groove 51, the positioning groove 52 and the positioning block 53 are all T-shaped structures. Under this action, the force-bearing area between the positioning block 53 and the fixing groove 51 and the positioning groove 52 can be increased, effectively improving the limiting effect of the cover 3.

[0024] Working principle: Firstly, during rain, rainwater flows into the collection tank 10 through the infiltration trough 4. The filter screen 11 filters out foreign objects, and the rainwater then flows into the sewer pipe. During heavy rainfall, rainwater can be discharged through the drain hole 12, which blocks floating foreign objects. This effectively separates various foreign objects, reducing the amount of debris in rainwater and improving the device's applicability. When cleaning the collection tank 10 is required, workers... After the operator pulls the cover 3 and rotates it, the positioning block 53 can be moved out of the positioning groove 52 and slide into the fixing groove 51. Then, the connection between the fixing groove 51 and the positioning block 53 is released, thereby removing the cover 3. Then, with the cooperation of the movable groove 13, the dirt collection shell 10 is removed and cleaned. After cleaning, the dirt collection shell 10 is placed back in its original position, and then the cover 3 is returned to its original position. This fixing method can effectively improve the stability of the cover 3 during use and reduce the situation where the cover 3 slides randomly and affects safety.
