Description

Technical Field

[0001] The utility model relates to the technical field of filter wells, and specifically relates to an inner liner of a filter well with a sewage interception function. Background Art

[0002] Filter wells are used for urban drainage or garden drainage. Their main function is to recycle rainwater and use the collected rainwater to irrigate green plants or discharge it into other water storage devices.

[0003] When a filter well is actually used, it needs to be buried underground, and only its open end faces above the ground for collecting rainwater. Because it is hollow inside, it is prone to deformation under pressure after being buried underground. Therefore, an inner liner needs to be installed inside it to strengthen its overall structural strength. Moreover, during the process of collecting rainwater, the rainwater easily flushes impurities such as leaves and peels on the ground into the filter well, resulting in blockage at the drainage part of the filter well, thus affecting the drainage function of the filter well. Summary of the Utility Model

[0004] Based on the above problems existing in the prior art, the purpose of the embodiments of the present utility model is to provide an inner liner of a filter well with a sewage interception function, which can effectively intercept impurities entering the filter well, preliminarily filter the flowing water transported out of the filter well, strengthen the overall structural strength of the filter well, and avoid deformation of the filter well under the pressure of soil during landfill.

[0005] The technical solution adopted by the present utility model to solve its technical problems is: an inner liner of a filter well with a sewage interception function, including a main body. The main body includes an inner cylinder, a bottom plate, and a plurality of small-hole round nets. A plurality of mesh holes are opened on the inner cylinder. The bottom plate is arranged at one open end of the inner cylinder and covers the open end. The small-hole round nets are fixed on the inner cylinder. A plurality of small round holes are opened on the small-hole round nets, and the diameter of the small round holes on the small-hole round nets is smaller than the diameter of the mesh holes on the inner cylinder.

[0006] Further, the main body includes a plurality of vertical convex platforms, and the plurality of vertical convex platforms are all fixed on the outer side of the inner cylinder, and the plurality of vertical convex platforms are arranged along the circumferential direction of the inner cylinder.

[0007] Further, it includes a top cover. The top cover includes an arc-shaped net cover, and the arc-shaped net cover is arranged at the port of the inner cylinder far from the bottom plate.

[0008] Further, a ring one is fixed at the edge of the end of the inner cylinder far from the bottom plate. The ring one is fixedly connected to all the plurality of vertical convex platforms. A ring two is fixed at the end of the arc-shaped net cover close to the inner cylinder.

[0009] Further, it includes a fastening assembly, the fastening assembly includes a plurality of square bosses, a plurality of bolts and an outer ring. One end of the vertical boss away from the bottom plate is provided with a first threaded hole. A plurality of peripheral bosses are fixed on the outer side of the second ring. The plurality of peripheral bosses are arranged along the circumferential direction of the second ring. The peripheral bosses are provided with second threaded holes, and the first threaded hole and the second threaded hole are arranged correspondingly.

[0010] Further, the top cover includes a fixing plate and a handle. The fixing plate is fixed at the top end of the arc-shaped net cover, and the handle is fixed on the fixing plate.

[0011] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0012] 1. The inner cylinder is placed in the filter well, providing a layer of supporting force to the inner side of the filter well, strengthening the overall structural strength of the filter well. And by adding multiple vertical bosses, the structural strength of the inner cylinder can be further enhanced. When the inner cylinder is placed in the filter well, the vertical bosses are in contact with the inner wall of the filter well, so that when the filter well is buried underground, it is not easy to deform under the soil pressure.

[0013] 2. The mesh holes opened on the inner cylinder will not intercept the flow of rainwater, but will intercept impurities that fall into the inner cylinder and have a volume larger than the mesh holes, so that these impurities will not be discharged into other water storage devices along with the flow of rainwater, and the intercepted impurities will not enter the drainage device of the filter well, avoiding the drainage device from being blocked due to excessive impurities.

[0014] 3. By adding a small-hole round net on the inner cylinder and aligning the small-hole round net with the drainage device of the filter well, finer impurities can be intercepted, avoiding the situation of blockage caused by these impurities entering the drainage device of the filter well.

[0015] 4. The added arc-shaped net cover will not intercept the flow of rainwater, but will intercept large-volume impurities that fall above the arc-shaped net cover, preventing them from falling into the inner cylinder. And the arc-shaped setting of the arc-shaped net cover can make the overall top cover above the inner tank protrude above the ground after the filter well is buried underground, which is easy to observe, avoiding pedestrians on the ground from accidentally stepping on the top cover. And this arc-shaped setting can strengthen the overall structural strength of the top cover, and it is not easy to collapse even if it is stepped on. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Now, the present utility model will be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present utility model in a schematic manner, so it only shows the components related to the present utility model.

[0033] Please refer to Figures 1-5 , the present utility model provides a technical solution: a filter well inner liner with a sewage interception function, including a main body 1, a top cover 2 and a fastening assembly 3.

[0036] A plurality of vertical convex platforms 13 are all fixed on the outer side of the inner cylinder 11, and the plurality of vertical convex platforms 13 are arranged along the circumferential direction of the inner cylinder 11.

[0037] The small-hole circular screen 14 is fixed on the inner cylinder 11. A plurality of small round holes are provided on the small-hole circular screen 14, and the diameter of the small round holes on the small-hole circular screen 14 is smaller than the mesh holes on the inner cylinder 11.

[0038] The first ring 15 is fixed to the edge of the end of the inner cylinder 11 away from the bottom plate 12, and the first ring 15 is fixedly connected to all the vertical bosses 13.

[0039] The top cover 2 includes an arc-shaped mesh cover 21, a second ring 22, a plurality of peripheral bosses 23, a fixing plate 24 and a handle 25.

[0040] The arc-shaped mesh cover 21 is arranged on the port of the inner cylinder 11 away from the bottom plate 12, and the second ring 22 is fixed to one end of the arc-shaped mesh cover 21 close to the inner cylinder 11.

[0041] A plurality of peripheral bosses 23 are fixed to the outside of the second ring 22. The plurality of peripheral bosses 23 are arranged along the circumferential direction of the second ring 22, and threaded holes two 230 are provided on the peripheral bosses 23.

[0042] The fixing plate 24 is fixed to the top end of the arc-shaped mesh cover 21, and the handle 25 is fixed to the fixing plate 24.

Threaded holes one 130 are provided at the ends of the vertical bosses 13 away from the bottom plate 12, and the threaded holes one 130 and the threaded holes two 230 are arranged correspondingly.

[0044] The inner cylinder 11 is placed in a filter well (not shown in the figure), providing a layer of support force for the inner side of the filter well and strengthening the overall structural strength of the filter well. Moreover, by adding a plurality of vertical bosses 13, the structural strength of the inner cylinder 11 can be further enhanced.

Additionally, this arc-shaped design can strengthen the overall structural strength of the top cover 2, making it not easily collapse even when being stepped on.
