Description

Technical Field

[0001] This application relates to the field of water supply and drainage technology, and more specifically, to a highly durable roadbed drainage system. Background Technology

[0002] Water supply and drainage, as urban water supply systems, drainage systems (municipal water supply and drainage), and building water supply and drainage, contribute to environmental protection through municipal development policies and energy conservation and emission reduction, and further promote the rapid development of the construction industry.

[0003] The prior art publication (announcement) document with the number CN220224816U provides a road construction subgrade drainage structure. In this related technology, a scraper is set up. When a lot of impurities accumulate on the upper part of the filter cover, the motor is turned on to drive the rotating shaft to rotate. The rotating shaft drives the rotating plate to rotate, and the rotating plate drives the scraper at the lower end to rotate, thereby scraping away the impurities on the upper part of the filter cover. By setting up the scraper, the upper part of the filter cover can be cleaned, avoiding the blockage caused by a lot of impurities adhering to the upper part of the filter cover, which affects the drainage speed of the filter cover.

[0004] Although the existing technical solutions described above can achieve the relevant beneficial effects through the existing technical structure, they still have the following defects: Although the motor can drive the scraper to ensure that the filter cover is in a good filtration environment, the motor needs to be electrically driven, and the drain pipe needs to be in contact with the water. If the motor's power line experiences a short circuit or leakage, it can easily cause an accident.

[0005] In view of this, we propose a high-durability roadbed drainage system. Utility Model Content

[0006] To address the problems mentioned in the background art, this application provides a highly durable highway subgrade drainage system.

[0007] The high-durability highway subgrade drainage system provided in this application adopts the following technical solution:

[0008] A high-durability highway subgrade drainage system includes:

[0009] Drainage pipe;

[0010] The filter plate is inserted and installed in the middle of the drain cylinder;

[0011] The residue filter cartridge is slidably connected between the separator filter plate and the drain cylinder;

[0012] The drainage well cover is hinged and installed at one end of the drainage cylinder.

[0013] The filter screen is hinged to one side of the drainage well cover and can abut against and limit the movement of the partition filter plate.

[0014] By adopting the above technical solution, the filter screen plate and the partition filter plate are brought into contact to form a slope, thereby filtering the sewage discharged through the drainage well cover. The sewage falls into the residue filter cartridge for solid-liquid separation and discharge, improving the drainage effect of the drainage cartridge structure. In addition, the water dripping from the residue filter cartridge can pass through the bottom of the partition filter plate for convergence, further improving the performance of the residue filter cartridge.

[0015] As an optional solution to the technical solution of this application, a column is fixedly connected to the middle of the residue filter cylinder, a support column is slidably connected inside the column, the support column and the column are elastically limited by a spring, and a roller handle that can roll and rub against the filter screen is fixedly connected to one end of the support column.

[0016] By adopting the above technical solution, the filter screen plate is elastically supported by the elastically connected support column, which provides elastic support for the hinged filter screen plate, making it convenient for solid-liquid separation. The filter screen plate shakes when impacted by discharged sewage, maintaining its filtration effect. The roller handle fixedly installed at one end of the support column can stretch the support column and the column cylinder to slide and extend, making it convenient to extract and clean the residue filter cartridge.

[0017] As an optional solution to the technical solution of this application, two screw sleeves are fixedly connected to the outside of the column, and a reinforcing rod is threadedly connected to the inside of the screw sleeve. The other end of the reinforcing rod is inserted into the residue filter cartridge, and a roller is rotatably connected to one side of the reinforcing rod.

[0018] By adopting the above technical solution, the reinforcement rod with added rollers can not only improve the smoothness of the placement of the residue filter cartridge between the separator filter plate and the drainage cylinder, but also improve the stability of the column installation.

[0019] As an optional solution to the technical solution in this application, a reinforcing frame that can support and limit the drainage cylinder is fixedly connected to one side of the drainage well cover, and a rubber ring is fixedly connected to the outside of the reinforcing frame.

[0020] By adopting the above technical solution, the supporting strength of the drainage well cover can be improved by using the reinforcing frame, and it can maintain a stable fit with the drainage cylinder under the action of the rubber ring, thus ensuring the stability of the drainage well cover closure.

[0021] As an optional solution to the technical solution in this application, the filter plate has multiple water guide grooves on its surface.

[0022] By adopting the above technical solution, the water guide channel can improve the solid-liquid separation effect of the filter screen plate and avoid the accumulation of debris on the surface of the filter screen plate, which would affect water filtration.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This application utilizes the contact between the filter screen plate and the partition filter plate to form a slope, thereby filtering the sewage discharged through the drainage well cover and allowing it to fall into the residue filter cartridge for solid-liquid separation and discharge. This improves the drainage effect of the drainage cartridge structure, and the water dripping from the residue filter cartridge can pass through the bottom of the partition filter plate for confluence, further improving the performance of the residue filter cartridge.

[0025] 2. This application utilizes a support column with elastic connection to provide elastic support for the filter screen plate, which is installed in a hinged manner. This facilitates the use of the filter screen plate for solid-liquid separation. The filter screen plate is shaken by the impact of discharged sewage, maintaining its filtration effect. The roller handle fixedly installed at one end of the support column can stretch the support column and the column cylinder to slide and extend, which facilitates the convenient operation of extracting and cleaning the residue filter cartridge.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] Reference Figure 1-3 The present application describes a high-durability highway subgrade drainage system, comprising:

[0032] Drainage cylinder 1;

[0033] The separator filter plate 2 is inserted and installed in the middle of the drain cylinder 1;

[0034] The residue filter cartridge 3 is slidably connected between the partition filter plate 2 and the drain cylinder 1;

[0035] Drainage well cover 4 is hinged to one end of drainage cylinder 1;

[0036] The filter screen 5 is hinged to one side of the drainage well cover 4 and can abut against and limit the position of the partition filter plate 2.

[0037] This highly durable roadbed drainage system utilizes a filter screen plate 5 to abut against a partition filter plate 2, forming a slope to filter sewage discharged through the drainage well cover 4. The sewage then falls into the residue filter cartridge 3 for solid-liquid separation and discharge, improving the drainage effect of the drainage cartridge 1. Furthermore, the water drained from the residue filter cartridge 3 can pass through the bottom of the partition filter plate 2 for confluence, further enhancing the performance of the residue filter cartridge 3.

[0038] Reference Figure 2 and Figure 1 In the high-durability highway subgrade drainage system described in this application embodiment, a column cylinder 31 is fixedly connected to the middle of the residue filter cartridge 3. A support column 32 is slidably connected inside the column cylinder 31. The support column 32 and the column cylinder 31 are elastically limited by a spring. One end of the support column 32 is fixedly connected to a roller handle 33 that can roll and rub against the filter screen plate 5. Two screw sleeves 34 are fixedly connected to the outside of the column cylinder 31. A reinforcing rod 35 is threadedly connected inside the screw sleeve 34. The other end of the reinforcing rod 35 is inserted into the residue filter cartridge 3. A roller is rotatably connected to one side of the reinforcing rod 35.

[0039] This highly durable roadbed drainage system utilizes the elastically connected support column 32 to elastically abut against the filter screen plate 5, providing elastic support for the hinged filter screen plate 5. This facilitates solid-liquid separation of the filter screen plate 5. It shakes under the impact of discharged sewage, maintaining its filtration effect. The roller handle 33 fixedly installed at one end of the support column 32 can extend the support column 32 and the column cylinder 31, facilitating convenient operation for the extraction and cleaning of the residue filter cartridge 3. The reinforcing rod 35 with added rollers not only improves the smoothness of placing the residue filter cartridge 3 between the separator filter plate 2 and the drainage cylinder 1, but also enhances the stability of the column cylinder 31 installation.

[0040] Reference Figure 3 and Figure 1 In the high-durability roadbed drainage system described in this application embodiment, a reinforcing frame 41 is fixedly connected to one side of the drainage well cover 4, which can support and limit the drainage cylinder 1, and a rubber ring is fixedly connected to the outside of the reinforcing frame 41.

[0041] This highly durable roadbed drainage system utilizes a reinforcing frame 41 to enhance the support strength of the drainage well cover 4 and maintains a stable fit with the drainage cylinder 1 under the action of the rubber ring, ensuring the stability of the drainage well cover 4 when closed.

[0042] Reference Figure 3 and Figure 1In the high-durability highway subgrade drainage system described in this application embodiment, the filter screen plate 5 has multiple water guide grooves on its surface.

[0043] This highly durable roadbed drainage system can improve the solid-liquid separation effect of the filter screen 5 by using a water guide channel, and avoid the accumulation of debris on the surface of the filter screen 5, which would affect water filtration.

[0044] Working principle: When rainwater flows down the drainage well cover 4 into the drainage cylinder 1 during rainy weather, the rainwater mixture undergoes solid-liquid separation by passing through the filter screen 5, which is placed at an angle and is elastically abutted by the roller handle 33.

[0045] At this time, the filtered water falls into the bottom of the drain cylinder 1 and is discharged through the drain pipe. The debris intercepted on the surface of the filter screen 5 falls into the residue filter cylinder 3 for filtration due to its inclined structure and the impact of falling rainwater. The drained water is collected and discharged through the bottom opening of the separator filter plate 2.
