Description

The head for an emergency self-flowing well of groundwater deposits belongs to the field of technical means necessary to prevent outflows from emergency self-flowing wells that are not equipped with a connecting flange.

Known head of the well [1, Patent for utility model No. 159851, Head for an emergency observation self-flowing well], including a flange plug with an opening 1, a vertical steel pipe with an external thread 2, a steel cap with an internal thread 3, a steel outlet 4, a ball valve 5 , an adapter for water sampling and connection of a pressure gauge 6, a rubber seal 7, a removable sleeve housing 8, a gland seal 9, a pressure sleeve 10, tightening bolts 11, a bolt connection 12. The head design is shown in figure 1.

This head has the following disadvantages:

- significant metal consumption;

- high labor intensity of manufacturing.

The closest to the proposed device is the head [2, Patent for utility model No. 164052, Head of the observation self-flowing well], including: a protective steel casing with a flange 13, a flexible flange plug 14, a bolted connection 12, a fastener 15 connected to submersible autonomous sensors and recorders, a cable for attaching a submersible autonomous sensor or recorder 16, a seal 7. The design of the head is shown in figure 2.

This head has the following disadvantage:

- There is no possibility of using it in wells not equipped with a flange connection.

The technical result of the utility model is a decrease in metal consumption, a decrease in the labor intensity of manufacturing.

The technical result is achieved by the fact that a head for an emergency self-flowing well of groundwater deposits is proposed containing: a protective steel casing with a flange 13, a flexible flange plug 14, a bolted connection 12, a seal 7 combined with a flexible flange plug 14, a steel flat flange 17, elongated nuts 18 attached to a steel flat flange 17 by means of a welded joint 21, locking bolts 19 are screwed into elongated nuts 18, while the locking bolts 19 are recessed into the chamfers 20 located on the outer surface of the casing 22 of the emergency self-flowing well.

The utility model is illustrated by the drawings shown in figures 3 and 4. Figure 3 shows a drawing of the design of the proposed head (general view). Figure 4 shows a design drawing of a steel flat flange (assembly drawing).

The head is mounted as follows:

On the casing 22 of an emergency self-flowing well, not equipped with a connecting flange, a steel flat flange 17 is inserted with elongated nuts 18 attached to it using a welded joint 21. A steel flat flange 17 is fixed 5 mm below the edge of the casing 22 of an emergency self-flowing well with locking bolts 19 screwed into the elongated nuts 18 to the stop. Further, the locking bolts 19 are loosened, leaving an impression on the casing 22. At the places of the impressions, using a cordless drill or an angle grinder, chamfers are made 20.

The steel flat flange 17 is again fixed with locking bolts 19 at the edge of the casing 22, while the locking bolts screwed into the elongated nuts 18 are recessed to the stop in the chamfers 20.

Protective steel casing 13, flexible flange plug 14 are installed on a steel flat flange 17, fixed on the edge of the casing 22 of an emergency self-flowing well, bolted connection 12 is inserted from below through the holes of the steel flat flange 17 and compresses the protective steel casing 13, flexible flange plug 14 until terminated pouring water from an emergency self-flowing well, while the flexible flange plug 14 simultaneously serves as a seal 7.

When an ice plug forms in the casing 22 of an emergency self-flowing well, a flexible flange plug 14, made of sheet rubber 10 mm thick, sags into the cavity of a protective steel casing 13 under ice pressure, reducing the pressure on the walls of the surface part of the casing 22 of an emergency self-flowing well and restores the original shape when ice melts.

An assembly drawing of a steel flat flange 17 is shown in figure 4.

The use of the proposed head provides, in comparison with the currently used head, the following advantages:

- reduction of metal consumption ≈ by 50%;

- Reducing the labor intensity of manufacturing ≈ 80%.

The proposed device is advisable to use when eliminating spills from emergency self-flowing wells not equipped with a connecting flange.
