The implementation of the invention

In Fig.1 shows a drainage device, indicated by the General position 2.

The device 2 is installed on a horizontal or slightly sloping roof of the building and is designed to remove rainwater that accumulates on this roof when its amount exceeds the first level N1.

The device 2 includes a drain pipe 6, a reservoir tank 8 and a drainage device 10.

The drainpipe 6 is made vertically around the vertical axis XX and its upper end defines a circular drain 12 with a diameter D1.

In the future, the expressions “axial”, “radial” and “circumferential” will be used relative to the axis XX.

The collector tank 8 contains a drain funnel 14. A drain 12 is made in the center of the bottom of the funnel 14. The neck 16 is connected to the upper edge of the funnel 14. The neck 16 is made at level N1 and forms an annular space with an inner diameter D2 and an outer diameter D3.

Three threaded rods 18 protrude from the surface of the neck 16 from the side opposite to the pipe 6.

The pipe 6 and the reservoir tank 8 are bodies of revolution around the axis XX.

The drainage device 10 is designed to direct water into the drain 12 without the formation of air bubbles and to trap debris such as leaves.

The drainage device 10 includes a round flat cover 20. It is located perpendicular to the axis XX at level N2. The diameter of the cover 20 is identical to the outer diameter D3 of the neck 16. The cover 20 is spaced from the neck 16 by a distance d. The distance d is a filtration gap of, for example, 15 mm. Thus, the detention of objects whose smallest size exceeds d. The edges of the cover 20 and the neck 16 define between themselves a drain channel 21, made in the circumferential direction around the axis XX.

As shown in FIG. 2, the cover 20 comprises a central zone 22 opposite the gutter 12 and a peripheral zone 24 covering the central zone 22. The central zone 22 is formed by a solid wall and has a diameter equal to the diameter D2.

The peripheral zone 24 contains three spill holes 26, as well as three mounting holes 28 (figure 3).

горловины 16. Контур каждого отверстия 26, обозначенный позицией 30, состоит из двух концевых радиальных участков 32, 34 и двух окружных участков - наружного 36 и внутреннего 38.The spill holes 26 are completely opposite the neck 16, have an elongated shape and are made along the periphery of the cover 20. In the axial form, each hole has a cross section in the form of a round ring. Each hole has a constant width and has an arcuate shape centered on the x-axis. The holes 26 are evenly distributed around the axis XX, and each hole is located in one angular range α of 90 °. Preferably, the spillways are located in a general angular range in the range of 240 ° to 300 °. The width L1 of the hole 26, measured radially, is less than the radial width

the neck 16. The contour of each hole 26, indicated by 30, consists of two end radial sections 32, 34 and two circumferential sections - outer 36 and inner 38.

The guide drainage protrusions 40 are made starting from the side of the lid 20 facing the tank 8. They extend to the neck 16 (FIG. 1), passing through the drain channel 21. As shown in FIG. 3, each hole 26 is equipped with two such protrusions 40. Each protrusion 40 contains a radial branch 44 made along the corresponding end radial section 32, 34, as well as a circular branch 48 made along part of the section of the inner circumferential contour 38. The circular branch 48 is adjacent to the radial branch 44. The length of these two branches 44, 48 along creatures identical, with each projection 40 axially has a general L-shape.

The drainage device 10 further comprises filtering means configured to filter the fluid passing through the openings 26. As shown in FIGS. 2 and 4, these filtering means comprise a plurality of radial ribs 50 formed on the lid 20 and protruding axially from the opposite side Baku 8.

The ribs 50 are made over the spillways 26 at a distance d, measured at their radially outer ends. Thus, this distance d is equal to the filtration gap. Preferably, the radial width L2 of the ribs 50 is from 1.5 to 2.5 of the radial width L1 of the spillway 26. In this case, the radial width L2 is essentially equal to the double width L1.

The axial height H of each rib is 1.5-4 times greater than the axial height d of the protrusions 40. The upper axial end of the ribs 50 determines the level of N3.

Each rib 50 is equipped with a cell 52, open in the axial direction towards the spillway and made through in the circumferential direction.

The ribs 50 of each hole 26 contain lateral ribs 50A located on the peripheral end of each hole 26. The height of the cell 52A of each of these ribs 50A is equal to d, that is, equal to the filtration gap.

The height of the cells 52A of these side ribs is less than the height of the cells 52 of the ribs 50 located between the side ribs 50A.

The implementation of the cells 52, 52A can reduce the amount of material required for the manufacture of drainage device 10.

The side ribs 52A of two adjacent holes 26 are at a mutual distance greater than the filter gap d. Thus, the drainage device forms a radial channel 54 for the passage of fluid that does not contain filtering means. When the liquid level is between levels N2 and N3, unfiltered liquid can flow into the central zone 22 and is filtered radially by the inner part of the ribs 50.

In addition, the device 2 contains three nuts 60, screwed on the rods 18 and pressing the drainage device to the neck 16.

The drainage device 10 is performed by molding in the form of a single part.

The drainage device is as follows:

Perform a monoblock drainage device 10.

A collector tank 8 is welded to the upper end of the drainpipe 6.

After that, a drainage device 10 is installed on the neck 16 and fixed on it with the help of nuts 60.

Thus, it can be noted that the installation of system 2 is not difficult and does not require much time.

The drainage system operates as follows.

Ribs 50 form a large filtration space.

When the water level is above the neck 16 and under the cover 20, that is, between the level N1 and the level N2, water flows in a laminar flow between the neck 16 and the cover 20 and is removed through the drain 12. In this operating mode, the drain holes 26 and ribs 50 are not included contact with water.

When the water level is above the lid 20, but below the upper end of the ribs 50, that is, between the levels N2 and N3, the first part E1 of the water flows radially between the neck 16 and the lid 20. The second part E2 flows radially into the interior through the slots between the ribs 50. The third part of the EZ flows radially inward through the channels 54, then in the radial direction outward through the gaps between the ribs 50.

After passing through the cracks between the ribs 50, the water flows axially through the drainage holes 26, and then is discharged in the radial direction towards the axis X-X (arrow E).

If the water level exceeds the level E3, the side of each rib 50 located opposite to the cover 20 also participates in the filtering.

Radial bends 44 of the protrusions 40 prevent the formation of turbulence, while the circumferential bends 48 contribute to an even distribution of water pressure on the cover 20. As a result, water flows through the laminar flow between the cover 20 and the neck 16, without sucking air into the pipe 6. Thus, the device 2 operates in the so-called siphon mode.

The manufacture and assembly of the device 2 in accordance with the present invention is not difficult due to the implementation of the drainage device 10 in one piece. In addition, the device 2 allows you to provide high throughput at a given pipe diameter due to the laminar fluid flow and a large filtering area.

In addition, the design of ribs 50 facilitates cleaning of the device. In addition, the drainage device 10 in accordance with the present invention allows the use of pipes of different diameters while maintaining good spillway efficiency.
