Description

Technical Field

[0001] The utility model relates to the technical field of inspection wells, in particular to a plastic inspection well with the function of collecting sediment in rainwater. Background Art

[0002] Inspection wells are set up for the maintenance of urban underground infrastructure such as power supply, water supply, drainage, sewage, communications, cable TV, gas pipes, and street light lines. They are easy to install and are generally located at pipeline intersections, bends, places where pipe diameters or slopes change, and at certain intervals on straight pipe sections to facilitate regular inspection of ancillary structures.

[0003] When it rains, water on the road often carries a lot of mud and sand and flows into the inspection well through the holes in the manhole cover. A large amount of mud and sand will cause the inspection well to accumulate in the pipe and cause pipe blockage. For this reason, we propose an inspection well with a device for collecting mud and sand in rainwater.

[0004] The existing patent (publication number: CN205224238U) discloses a rainwater inspection well, including a well seat, a transverse pipe, a sludge chamber and a collecting bucket, wherein the well seat is a vertical and bottomless barrel-shaped structure, there are at least two transverse pipes and they are horizontally arranged on the side wall of the well seat, the sludge chamber is a barrel-shaped structure connected to the lower end of the well seat, the collecting bucket is arranged in the sludge chamber and the outer diameter of the collecting bucket is slightly smaller than the inner diameter of the sludge chamber, and a lifting lug is arranged on the upper end of the collecting bucket. The utility model collects the deposited silt through the collecting bucket, and when the silt needs to be removed, the collecting bucket only needs to be lifted and taken out through the lifting lug to clean the silt in the collecting bucket, which makes the cleaning work very convenient, saves manpower, greatly improves the cleaning efficiency, and also makes the cleaning effect better. In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. The existing inspection wells are unable to filter and collect the silt in the rainwater after it enters the well body, causing the silt in the rainwater to enter the well body, thereby causing blockage of the well body; 2. After the inspection well has been used for a long time, the silt in the rainwater will cause a certain blockage to the filtering mechanism of the inspection well. The traditional inspection wells are unable to effectively deal with the silt on the surface of the filtering mechanism and need to be cleaned manually regularly, which greatly reduces the practicality of the inspection well itself. Utility Model Content

To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plastic inspection well with the function of collecting sediment in rainwater, comprising an outer shell assembly and a filter box, two first filter screens are embedded in the inner bottom end of the filter box, collecting grooves are arranged at the bottom ends of both sides of the filter box, and second filter screens are embedded in the inner bottom ends of the two collecting grooves, an annular positioning block is arranged at the outer top end of the filter box, a plurality of first through holes are opened inside the annular positioning block, a mounting plate is arranged between the two inner walls of the outer shell assembly, an annular fixing seat is arranged at the top end of the mounting plate, a sedimentation box is arranged inside the annular fixing seat, and a plurality of second through holes are opened inside the mounting plate.

[0022] In this embodiment, Figure 1 As shown, the housing assembly 1 includes a well seat 101, a well body 102 is arranged at the top of the well seat 101, an annular groove 103 is opened at the top of the well body 102, a plurality of positioning rods 104 are arranged at the inner bottom end of the annular groove 103, a cover plate 105 is arranged at the top of the well body 102, and a plurality of water inlet holes 106 are opened inside the cover plate 105.

[0023] In this embodiment, Figure 4 As shown, the inner dimensions of the annular fixing seat 9 are consistent with the outer dimensions of the bottom end of the sedimentation box 10, thereby fixing and limiting the sedimentation box 10 to avoid displacement of the sedimentation box 10 during use, thereby greatly improving the stability of the sedimentation box 10 during use.

[0024] In this embodiment, Figure 3 As shown, the two first filter screens 3 are configured as inclined structures; by utilizing the inclined first filter screens 3, larger impurities and silt on the surface of the first filter screens 3 can slide smoothly into the interior of the collecting tank 4 by utilizing their own gravity, thereby greatly improving the cleaning efficiency of the silt on the surface of the first filter screens 3.

[0025] In this embodiment, Figure 1 As shown, the collecting trough 4 and the second filter screen 5 are symmetrical about the central axis of the well body 102, thereby filtering the sediment mixed in the rainwater and solving the problem that the sediment in the rainwater enters the well body 102 and causes blockage in the plastic inspection well.

[0026] In this embodiment, Figure 1 As shown, a plurality of diversion holes are respectively provided on both sides of the sedimentation box 10, so as to discharge the rainwater inside the sedimentation box 10 and perform secondary filtration on the sediment in the rainwater.

[0028] The use method and advantages of the utility model: When the plastic inspection well with the function of collecting sediment in rainwater is used, the working process is as follows:

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, firstly, the well body 102 is preset in the specified position through the well seat 101, and then the sedimentation box 10 is placed inside the annular fixing seat 9, and then the filter box 2 is placed inside the well body 102. At this time, the first through hole 7 on the annular positioning block 6 outside the filter box 2 is plugged into the outside of the positioning rod 104, and then the filter box 2 is fixed by a nut, so as to fix the position of the filter box 2, greatly increasing the stability of the filter box 2 during use, and then the cover plate 105 is covered, wherein rainwater enters the interior of the filter box 2 through the water inlet hole 106 on the surface of the cover plate 105, and the first filter screen 3 filters the larger sediment in the rainwater. By using the inclined first filter screen 3, the larger impurities and sediment on the surface of the first filter screen 3 can be smoothly slid into the inside of the collecting tank 4 by their own gravity, which greatly improves the cleaning efficiency of the sediment on the surface of the first filter screen 3 and avoids When the silt blocks the first filter screen 3, the silt that enters the collection trough 4 is secondary filtered for the rainwater in the silt under the filter box 2 of the second filter screen 5, thereby effectively filtering and collecting the silt in the rainwater that enters the well body 102. The sedimentation box 10 can settle the silt in the rainwater, effectively preventing a large amount of silt from entering the well body 102 and affecting the flow of rainwater in the well body 102. When the rainwater reaches a certain height inside the sedimentation box 10, the rainwater will be discharged to the inside of the sedimentation box 10 through the diversion hole, and finally the rainwater after double filtration will enter the inside of the well seat 101 through the second through hole 11, thereby filtering the silt mixed in the rainwater, solving the problem of silt in the rainwater entering the well body 102 and causing blockage in the plastic inspection well, thereby meeting the demand for plastic inspection wells with the function of collecting silt in rainwater.
