Description

The utility model relates to the field of technical means necessary to provide remote control of groundwater parameters under various climatic conditions.

A set of devices is known [1, Solinst 9500 Levelsender], including: base 1, cover 2, fastener 3 holding the transmitting telemetry station 4, while the sensors-recorders 6 are connected to the transmitting station with direct reading cables 5. The design of the set of devices is shown in figure 1 .

This set of devices has the following disadvantages:

- Casing diameters for observation wells in the Russian Federation may not match the inner diameter of the head base;

- The use of plastics as a structural material for well heads operated in the northern regions will lead to a decrease in structural strength.

- The base of the set of devices is not adapted for the use of an acoustic level gauge.

Also known head [2, patent for utility model No. 164052, Head observation self-flowing well], containing: flange plug 8, a protective steel casing with a flange 7, fastener 3 connected to submersible autonomous sensors - recorders 6, flexible flange plug combined with seal 11, while the fastener connected to the autonomous submersible sensors and recorders, the protective casing and the flexible flange plug are connected to the well casing flange using a common bolted connection 9. The design of the head is shown in figure 2.

This heading has the following drawback:

- cannot be used in wells with a static level below the ground surface.

Closest to the proposed device is the head [3, Patent for utility model No. 200932, Emergency self-flowing well head], including a protective steel casing with a flange 7, a flexible flange plug 8, a bolted connection 9, a sealant 11, combined with a flexible flange plug, and also equipped with a steel flat flange 12, elongated nuts 13 attached to the steel flat flange by means of a welded joint 16, lock bolts 14 screwed into the elongated nuts, while the lock bolts are sunk into chamfers 15 located on the outer surface of the emergency self-flowing well casing. The design of the head is shown in figure 3.

This heading has the following drawback:

- cannot be used in wells with a static level below the ground surface.

The technical result of the utility model is to provide remote control of groundwater parameters under various climatic conditions.

The technical result is achieved by the fact that the head of the observation well for groundwater intakes is proposed, containing: a steel flat flange 12, elongated nuts 13, welded joints of elongated nuts 16, locking bolts 14, a sealant 11, a bolted connection 9, a steel flange plug with technological holes 17 bolted 9 to a steel flat flange 12, the heat-insulating casing 18 is attached to the steel parts by means of a locking connection of the heat-insulating casing 20, the protective cover 19 is located over the heat-insulating casing and attached to the casing with a waterproof adhesive tape.

The design of the proposed head is shown in figure 4. The design and attachment points of the locking joint of the heat-insulating casing are shown in figure 5.

The installation of the head is as follows:

A steel flat flange 12 with elongated nuts 13 attached to it is installed on the casing pipe of the observation well, which is not equipped with a connecting flange, using a welded joint 16. The steel flat flange is fixed on the edge of the well casing pipe with locking bolts 14 screwed into the elongated nuts 13 until it stops.

The steel flange plug with technological holes 17 is attached to the steel flat flange 12 using a bolted connection 9. The tightness between the steel flat flange 12 and the steel flange plug with technological holes 17 is provided by the seal 11. The plan view of the steel flange plug with technological holes 17 is shown in the figure 6.

Various autonomous measuring devices (acoustic level gauges, submersible sensors and recorders equipped with telemetric transmitting stations) can be installed in the central technological hole of the steel flange plug 17. The side technological hole is designed to control the accuracy of measuring the level of groundwater by autonomous measuring devices.

The heat-insulating casing 18 is attached to the lower and upper parts of the head with the help of locking connections 20. To prevent exposure to ultraviolet radiation, a protective cover 19 is located and attached to the casing with a waterproof adhesive tape over the heat-insulating casing.

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

- reducing the complexity of manufacturing;

- improvement of operating conditions;

- ensuring the reliability of remote control of groundwater parameters under various climatic conditions;

- the use of various measuring instruments (electric level gauges, acoustic level gauges, submersible sensors and recorders equipped with telemetric transmitting stations).
