In addition, there are known technical solutions that are close to those described above, but having additional significant features. For example, utility model patent No. 150047, published January 27, 2015, E03F 5/14 - a device for accommodating a filter cartridge having an overflow pipe, or utility model patent No. 151186, published March 27, 2015, E03F 5/14 - collapsible device for placing a filter cartridge.

The disadvantage of all of the above technical solutions is the high complexity of the exact location of the support ring relative to the wall reinforced concrete rings in contact with it.

The solution described in the patent for utility model No. 155863 is the closest in combination of essential features to the claimed utility model and is taken as a prototype.

Utility Model Essence

The objective of the claimed utility model is to offer a simple and convenient design of a device for accommodating a filter cartridge, which will allow to maintain an even location of the support ring relative to the wall reinforced concrete rings of the well during its arrangement.

The technical result of the utility model is to ensure sufficient accuracy of the location of the support ring relative to the adjacent reinforced concrete wall rings.

Hereinafter, the guaranteed provision of sufficient accuracy of the location of the support ring relative to the reinforced concrete wall rings in contact with it implies the possibility of installing the support ring on the reinforced concrete wall ring (and vice versa) with a guaranteed minimum displacement of the outer edge of the support ring relative to a predetermined position of the outer edge of the reinforced concrete wall rings.

This parameter is very important, since, on the one hand, the exact location of the support ring on the reinforced concrete wall ring in contact with it makes it possible to further position the filter cartridge on the support ring (if the ring is strongly shifted to the side, it will be extremely difficult to install a filter cartridge on it or impossible) and prevents water from seeping through the inventive device (support ring) from top to bottom (if the ring is strongly shifted to the side, then the untreated drain from above will be to get into the cleaned bottom without cleaning, which will negate the effect of using treatment facilities consisting of a filter cartridge and a support ring), and on the other hand simplifies the work of workers (and therefore increases their labor productivity) when installing a well and a support ring in it ( you don’t have to spend a lot of time manually aligning the support ring relative to the reinforced concrete wall ring in contact with it).

In the claimed utility model, the technical result is achieved in that the device for placing the filter cartridge inside the sewer well is made in the form of a ring with an opening for the location of the filter cartridge in it, has protrusions on the flat surface of the ring, located in such a way that at the points corresponding to their edges, located at an extreme distance from the center of the ring, you can draw a circle.

Brief Description of the Drawings

The utility model is illustrated by drawings, where:

 in FIG. 1 is a general view of the inventive device with a filter cartridge disposed in it in a sewer well;

 in FIG. 2 - appearance of the inventive device for placing a filter cartridge;

 in FIG. 3 is a diagram of the mutual arrangement of protrusions and wall reinforced concrete rings;

in FIG. 4 is a graph of the relationship between the main geometric characteristics of the protrusions from each other.

The proposed drawings illustrate the preferred embodiment of the utility model and therefore cannot be considered as limiting the content of the utility model, which does not include other embodiments.

Utility Model Implementation

In FIG. 1-4 are marked: 1 - reinforced concrete well; 2 - the claimed device (support ring); 3 - protrusions; 4 - filter cartridge; H - removal of the point corresponding to the edge of the protrusion from the center of the claimed device; A1, B1, B1, G1, D1 - special points of the edge of one protrusion; A2, B2, B2, G2, D2 - special points of the edge of another protrusion; α is the angle connecting the value of H and the position of the singular points; C1 and C2 - reinforced concrete wall rings of the well.

Standard reinforced concrete wall rings of wells according to GOST 8020-90, used in Russia, have a round shape, that is, they have a circle in cross section of the inner (C2) and outer (C1) cylindrical surfaces.

In FIG. 3 shows the inventive device (support ring) and two protrusions on it.

To ensure the possibility of installing the wall ring C1 (as indicated earlier, having a circular annular cross-section) on the claimed device with the achievement of a technical result, the protrusion limited by points A1, B1, B1, G1, D1 should not interfere with its installation at point D1, which (as shown in Fig. 4) has a minimum distance from the center of the claimed device.

To ensure the possibility of installing the wall ring C2 (as indicated earlier, having a circular annular cross section) on the claimed device with the achievement of a technical result, the protrusion limited by points A1, B1, B1, G1, D1 should not interfere with its installation at points B1 and B1, which (as shown in Fig. 4) have a maximum distance from the center of the claimed device.

For the second ledge bounded by points A2, B2, B2, G2, D2, and any other subsequent ledge, the situation is similar.

According to "Kuznetsov SA Large explanatory dictionary of the Russian language. Reference edition. - St. Petersburg: Norint, 2000. - 1536 p." the minimum (Nmin in Fig. 4) and maximum (Nmax in Fig. 4) of the possible values, that is, associated with the extremum of a certain function, are called extreme, therefore, to enable installation and ensure guaranteed accuracy of the location of the wall reinforced concrete rings C1 and C2 on the support the ring 2, the protrusions 3 on it should be positioned in such a way as to enable the circle to be drawn at points corresponding to the edges of the protrusions located at an extreme distance from the center of the ring.

Particular features in the form of the shape of the protrusions do not affect the achievement of the technical result, since protrusions of any shape, if a circle can be drawn at points corresponding to their edges located at an extreme distance from the center of the ring will ensure the achievement of the technical result, since, as can be seen from FIG. 3 and 4, a protrusion of any shape will have at least one point on its edge with a minimum (Nmin in Fig. 4) and at least one point on its edge with a maximum (Nmax in Fig. 4) distance from the center of the claimed device.

Features of particular forms in the form of the number of protrusions do not affect the achievement of the technical result, since any number of protrusions will ensure the achievement of the technical result if a circle can be drawn at the points corresponding to their edges located at an extreme distance from the center of the ring.

Features of particular forms in the form of the number of rows (circles) of protrusions do not affect the achievement of a technical result, since any number of rows of protrusions, if a circle can be drawn at points corresponding to their edges located at an extreme distance from the center of the ring, will ensure the achievement of a technical result. The presence of several rows of protrusions will provide the ability to use the inventive device (support ring) with reinforced concrete wall rings of different sizes, which expands the scope of the inventive support ring when achieving a technical result in each individual case, and also further increases the accuracy of the location of the support ring relative to the wall contacting it reinforced concrete rings, in the case of limiting them from the outside and from the inside at the same time (Fig. 1).

Features of particular forms regarding the choice of the flat side of the location of the protrusions do not affect the achievement of the technical result, which is achieved in each of the following cases, since:

- if the protrusions are located on the upper flat surface of the inventive support ring, they will ensure the achievement of a technical result relative to the wall reinforced concrete ring mounted on top of the inventive ring, if the protrusions are located on the lower flat surface of the inventive support ring, they will ensure the achievement of a technical result with respect to the wall reinforced concrete rings on which the claimed device is installed (support ring) (it should be noted that when turning the inventive device protrusions for placing the filter cartridge 180 degrees in space, the protrusions are on its upper or lower side, which also confirms the independence of the achievement of the technical result with respect to this variation of particular forms of execution of the device for placing the filter cartridge);

- if the protrusions are located simultaneously on the upper and lower planes of the surface of the claimed support ring, then they will ensure the achievement of a technical result both with respect to the wall reinforced concrete ring located above the claimed support ring, and under it.
