Description

Technical Field

[0001] This utility model relates to the field of rainwater inlet technology, specifically to an assembled rectangular plastic rainwater inlet. Background Technology

[0002] Stormwater drainage wells, essential building structures in modern cities, are typically installed on both sides of roads, their slope designed to guide rainwater to the drainage inlet and then into the sewer system. These inlets usually have cast iron end caps with holes to prevent large debris from entering and clogging the well, thus avoiding road flooding and traffic disruption. However, in daily life, besides larger debris, objects like leaves and pebbles often fall into the stormwater drainage wells due to water flow, eventually causing sewer blockages. Therefore, a prefabricated rectangular plastic stormwater inlet is needed.

[0003] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. After long-term use, a large amount of debris will accumulate in the intercepting basket of the rainwater inlet. The existing rainwater inlet cannot collect the debris in the intercepting basket in a unified manner, which makes it easy for the debris in the intercepting basket to clog the filter holes of the intercepting basket, thereby affecting the subsequent filtration effect of the intercepting basket on the debris in the rainwater; 2. When installing the existing rainwater inlet intercepting basket, it is mostly fixed by bolts. Bolt fixing requires the use of various auxiliary tools for installation, which is cumbersome, time-consuming and labor-intensive, thus greatly reducing the convenience of the intercepting basket during installation. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated rectangular plastic rainwater inlet to solve the problems mentioned in the background art, namely, that existing rainwater inlets cannot collect debris from the intercepting basket in a unified manner, causing the debris in the intercepting basket to easily clog the filter holes, thus affecting the subsequent filtration effect of the intercepting basket on debris in rainwater, and that existing rainwater inlets and intercepting baskets require various auxiliary tools for installation, thus greatly reducing the convenience of installation. To achieve the above objectives, this utility model provides the following technical solution: a prefabricated rectangular plastic rainwater inlet, including a shell assembly and a mounting plate, wherein an intercepting basket is provided at the bottom end of the mounting plate, a collection box is provided at the middle of the bottom end of the intercepting basket, a check plate is provided inside the collection box, two spring clips are provided on both sides of the mounting plate, a through groove is opened at the middle of the top end of the mounting plate, and two slots are opened on the two inner walls of the shell assembly.

[0005] More preferably, the outer casing assembly includes a rainwater inlet, with a water outlet at the bottom end of the rainwater inlet and an installation groove at the top end of the rainwater inlet.

[0006] More preferably, the internal dimensions of the mounting groove are consistent with the external dimensions of the mounting plate.

[0007] More preferably, the collection box has several through holes on its exterior and bottom.

[0008] More preferably, the bottom of the intercepting basket is designed as an inclined structure.

[0009] More preferably, the check plate is configured as an inverted conical structure.

[0010] More preferably, the spring block and the slot are configured with a snap-fit ​​structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this invention, the combination of the collection box, check plate, and through hole enables the assembled rectangular plastic rainwater inlet to collect and store debris in the intercepting basket during use. This solves the problem of long-term accumulation of debris in the intercepting basket causing blockage of the filter holes, thereby significantly improving the subsequent filtration effect of the intercepting basket on debris in rainwater.

[0013] In this utility model, the combination of spring clips, slots, and mounting plates enables the prefabricated rectangular plastic rainwater inlet to quickly install the intercepting basket during use, greatly improving the convenience of the intercepting basket during installation and significantly reducing the labor intensity of workers when installing the intercepting basket, thus meeting the requirements of prefabricated rectangular plastic rainwater inlets.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: an assembled rectangular plastic rainwater inlet, including a shell assembly 1 and a mounting plate 2. The bottom end of the mounting plate 2 is provided with a sewage interception basket 3, the bottom center of the sewage interception basket 3 is provided with a collection box 4, the inside of the collection box 4 is provided with a check plate 5, two spring clips 6 are respectively provided on both sides of the mounting plate 2, a through groove 7 is opened in the center of the top of the mounting plate 2, and two slots 8 are respectively opened on the two inner walls of the shell assembly 1.

[0021] In this embodiment, as Figure 1 As shown, the outer casing assembly 1 includes a rainwater inlet 101, a water outlet 102 is provided at the bottom of the rainwater inlet 101, and an installation groove 103 is provided at the top of the rainwater inlet 101.

[0022] In this embodiment, as Figure 4 As shown, the internal dimensions of the mounting groove 103 are consistent with the external dimensions of the mounting plate 2; this prevents the sewage basket 3 from shifting or becoming misaligned during use, thereby increasing the stability of the sewage basket 3 during use.

[0023] In this embodiment, as Figure 2 As shown, the collection box 4 has several through holes on its exterior and bottom, which enables the unified collection and storage of debris in the intercepting basket 3. This solves the problem of the filter holes of the intercepting basket 3 being blocked due to the accumulation of a large amount of debris in the intercepting basket 3 over a long period of time, thereby greatly improving the subsequent filtration effect of the intercepting basket 3 on debris in rainwater.

[0024] In this embodiment, as Figure 2 As shown, the bottom of the intercepting basket 3 is designed as an inclined structure. The inclined intercepting basket 3 can smoothly slide the debris into the collection box 4 by its own weight, thereby avoiding the accumulation of debris over a long period of time and causing blockage of the intercepting basket 3.

[0025] In this embodiment, as Figure 2 As shown, the check plate 5 is designed as an inverted cone-shaped structure. The check plate 5 can prevent debris flowing into the collection box 4 from flowing back into the intercepting basket 3, thereby increasing the applicability of the rainwater inlet 101 during use.

[0026] In this embodiment, as Figure 3 As shown, the spring clip 6 and the slot 8 are designed with a snap-fit ​​structure; this enables the rapid installation of the intercepting basket 3, greatly improving the convenience of the intercepting basket 3 during installation, thereby significantly reducing the labor intensity of the workers when installing the intercepting basket 3, and thus meeting the requirements of the prefabricated rectangular plastic rainwater inlet 101.

[0027] The method of use and advantages of this utility model: When using this assembled rectangular plastic rainwater inlet, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, firstly, the rainwater inlet 101 is fixedly installed in the designated position. Then, the intercepting basket 3 is inserted into the mounting groove 103 through the mounting plate 2. When the inner wall of the mounting groove 103 contacts the spring clip 6, the spring clip 6 moves towards the mounting plate 2 under pressure. When the spring clip 6 moves to the slot 8, the spring clip 6 uses its own elastic structure to engage with the inside of the slot 8, so that the spring clip 6 and the slot 8 form an engaging structure, realizing the rapid installation of the intercepting basket 3, greatly improving the convenience of the intercepting basket 3 during installation, and thus greatly reducing the labor intensity of the workers when installing the intercepting basket 3. When debris in the rainwater falls into the intercepting basket 3 through the channel 7, the intercepting basket... The waste basket 3 can filter debris in rainwater. The filtered rainwater will be discharged from the outlet 102 through the waste basket 3. The debris mixed in the rainwater will smoothly slide into the collection box 4 through the inclined waste basket 3. The collection box 4 can collect and store the debris in the waste basket 3 in a unified manner, which solves the problem of the waste basket 3 accumulating a large amount of debris over a long period of time and causing blockage of the filter holes of the waste basket 3. This greatly improves the subsequent filtration effect of the waste basket 3 on the debris in the rainwater. The check plate 5 can prevent the debris flowing into the collection box 4 from flowing back into the waste basket 3, thus meeting the requirements of the assembled rectangular plastic rainwater inlet 101.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
