RU154509U1 - OBSERVATIONAL WELL HEAD WITH STATIC LEVEL BELOW THE EARTH SURFACE - Google Patents

Abstract

The head of the observation well with a static level below the surface of the earth for fresh groundwater deposits, containing a flange plug with a hole; vertical steel pipe with external thread, steel cover with internal thread, characterized in that the head is equipped with a steel container for storing the control tag, while the container for the control tag is attached to the lid with a threaded connection and equipped with a rubber cone cap, the lid with an internal thread is provided rubber o-ring mounted in the groove of the steel pipe with external thread.

Description

The utility model relates to equipment installed on observation wells of fresh underground water fields and production wells that are being mothballed for sealing wells and conducting operational observations.

Known head observing wells with a variable static level [1, Utility Model Patent No. 139322, head observing wells with a variable static level]. The design of the head is shown in figure 1. The head contains; flange plug with hole 1; vertical steel pipe with external thread 2; steel cover with internal thread 3; steel branch 4; ball valve 5; adapter for sampling water and connecting a pressure gauge 6; tight connection of the pipe 2 with the cover 3 is carried out using a threaded connection 7 and a gasket 8.

This heading has the following disadvantages:

- the inability to attach a control tag;

- the inconvenience of placing the gasket.

Closest to the proposed device is the head of the well [2, p. 21, 3.12. fig. 3]. The design of the head is shown in figure 2. The head contains: head-cover 9: hanging control tag 10, lock head 11; branch pipe 12.

This heading has the following disadvantages:

- lack of tightness of the cap;

- the complexity of the manufacture and operation of the lock cap;

- unreliability of fastening of a control tag.

The technical result of the proposed head is to simplify the design of the head; decrease in its value; ensuring tightness of the well; increase the reliability of storage of the control tag.

The technical result is achieved by the fact that the proposed head of the observation well with a static level below the earth's surface for fresh groundwater deposits, containing a flange plug with a hole; a vertical steel pipe with an external thread, a steel cover with an internal thread, is equipped with a steel container for storing the control tag, while the container for the control tag is attached to the cover with a threaded connection and equipped with a rubber cone plug, the cover with a female thread is equipped with a rubber sealing ring installed in the groove of the steel pipe with external thread.

A general view of the design of the proposed head is shown in figure 3. It contains: a flange plug with a hole 1; vertical steel pipe with external thread 2: steel cover with internal thread 3. Figure 4 shows a steel container for storing the control tag 13, while the container for the control tag is attached to the cover using a threaded connection 14, the tightness of the container for the control tag is ensured by a rubber cone stopper 15, the cap with internal thread is sealed with a rubber sealing ring 16 installed in the groove of the steel pipe with external thread 2.

The operation of the head is as follows:

A steel cap with an internal thread 3 is unscrewed from a vertical steel pipe with an external thread 2, a hydrogeological device is put into the well that measures the operational parameters (static level, temperature, etc.) of groundwater in the well. At the end of the measurements, the rubber cone plug 15 and the control tag (sheet of paper) on which the results and date of measurements are recorded are removed from the steel container for storing the control tag 13. After recording the measurement results, the control tag is inserted into the steel container 13 and closed with a rubber cone plug 15. A steel cap with an internal thread 3 is screwed onto a vertical steel pipe with an external thread 2 until the rubber sealing ring 16 is installed in the groove of the steel pipe with an external thread 2.

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

- ensuring well tightness;

- simplification of the design of the head;

- reducing the cost of manufacturing the head;

- improving the reliability of storage control tags.

The proposed device is advisable to use for observation and mothballed production wells with a static level below the ground surface of fresh groundwater deposits located in unprotected areas.
