Description

The head for self-flowing wells of groundwater deposits belongs to the field of technical equipment necessary to ensure continuous hydrogeological monitoring of deposits using submersible autonomous sensors and recorders under various climatic conditions in unguarded territories.

Known head of the well [1, Utility Model Patent No. 133189, Head of the observation self-flowing well], including a valve 1; stopper 2; conical narrowing device 3; steel branch 4; vertical pipe 5; ball valve 6; adapter for sampling water and connecting a pressure gauge 7. The design of the head is shown in figure 1.

This heading has the following disadvantages:

- the inability to conduct continuous measurements of hydrogeological characteristics under various climatic conditions in unprotected areas;

- insufficient shockproof strength.

Closest to the proposed device is the head [2, Utility Model Patent No. 164052, Head of the observation self-flowing well], which contains a flange plug 10, a protective steel casing with a flange 9, a fastener 8 connected to immersion autonomous sensors and recorders, a flexible flange the plug 10 is combined with the seal 12, while the fastener 8 is connected to the cable 11 by means of which submersible autonomous sensors and recorders are suspended, a protective steel casing 9 and a flexible flange closure tab 10 connected to the flange of the well casing using a common bolted connection 13.

The design of the head is shown in figure 2.

This heading has the following disadvantages:

- it cannot be used at low temperatures on production and observation self-flowing wells equipped with gate valves;

- there is also no possibility of using it for continuous measurements of specific production rate of wells.

The technical result of the utility model is the automation of hydrogeological monitoring on self-flowing wells equipped with gate valves under various climatic conditions in unprotected territories, increasing the strength of the head and increasing the accuracy of the monitoring results.

The technical result is achieved by the fact that a head of a self-flowing well for groundwater deposits is proposed, comprising: a valve with a stopper, on which a conical constriction device is installed, connected to the valve using a bolt connection, and a steel tap, to which a ball valve with adapter for sampling water and connecting a manometer, a fastener connected to submersible autonomous sensors and recorders, characterized in that the fastener It is formed as a hairpin T-shaped, secured via a welded joint to the inner surface of the conical orifice, provided with a threaded connection for attaching the submersible autonomous sensors and registrars.

The utility model is illustrated by the drawings shown in figures 3 and 4. In FIG. 3 shows a drawing of a General view of the head. The tip contains: a valve 1, with a stopper 2, on which a conical constriction device 3 is installed, with a steel outlet 4, to which a ball valve 6 is connected via bolt connection, with an adapter 7 for sampling water and connecting a pressure gauge. In FIG. 4 shows a sectional view of a conical constricting device 3 with a tap portion 4. A fastener 8 made in the form of a L-shaped stud is connected to the inner surface of the conical constricting device 3 by means of a welded joint 15, which is a significant difference. The use of L-shaped studs simplifies the manufacture of the fastener 8 and ensures the reliability of its fastening to the inner surface of the conical constricting device. The fastener is provided with a threaded connection 14 for hard mounting of sensors and recorders, which is a significant difference. The use of a threaded connection 14 allows you to rigidly fix the sensors and recorders in the desired position (the vertical axis of the sensor coincides with the vertical axis of the conical constricting device), which improves the accuracy of the measurement results of the hydrogeological characteristics of groundwater.

The proposed utility model is illustrated by drawings:

FIG. 1 - Analog. General view of the head of an observing self-flowing well, utility model patent No. 133189;

FIG. 2 - Prototype. General view (sectional view) of the head of an observational self-flowing well, utility model patent No. 164052;

FIG. 3 - Utility model. General form.

FIG. 4 - Utility model. A section along the axis AA.

The utility model is as follows:

The valve 1 installed at the wellhead is closed and the head is dismantled. An autonomous sensor-recorder is programmed for the necessary mode of measuring the hydrogeological characteristics of groundwater. Then, the autonomous sensor-recorder is installed on the fastener 8, made in the form of a L-shaped pin, attached by means of a welded joint 15 to the inner surface of the conical constricting device 3 and rigidly fixed by means of a threaded connection 14. After that, the head equipped with the sensor-recorder is fixed to the valve 1 with a flange bolted connection 13, the valve 1 opens to ensure the required water flow.

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

- reducing the cost of conducting hydrogeological monitoring;

- ensuring continuous hydrogeological monitoring using submersible autonomous sensors and recorders on self-flowing wells equipped with valves, under various climatic conditions in unguarded territories;

- improving the accuracy of monitoring results;

- improving the reliability of the tip.

The proposed device is advisable to use when conducting continuous hydrogeological monitoring using self-contained immersion sensors and recorders in self-flowing production and observation wells equipped with valves, under various climatic conditions in unguarded territories.
