Description

The technical solution relates to the technique of marine research through buoy stations and can be used for complex observations of the hydrological parameters and the dynamics of the aquatic environment, as well as for chemical, biological and environmental control and monitoring of water areas covered with ice.

The specifics of setting buoy stations in ice-covered water areas are considered in well-known technical solutions [2, 3, 5, 6]. The design of buoy stations that can be used in ice conditions as subsurface modules is described in [1, 4, 7–9].

However, the limited functionality due to the specific purpose and use of a number of known devices [2, 3, 5, 6] prevents their adequate use for monitoring ice-covered water areas. So, in [6] the possibility of using buoy stations in Arctic ice conditions was only declared, in [5] an Arctic buoy was considered for communication with submarines. The general description of the principle of monitoring ice-covered water areas was given in [3], but the functionality of the equipment [3] is limited mainly by measuring temperature, salinity and pressure. The device [2] is intended mainly for monitoring the surface parameters of the atmosphere over ice, and the subsurface module is not disclosed, therefore, its industrial applicability for effective integrated monitoring is difficult.

When modifying the known devices [1, 4, 7-9], they can be used in water areas covered with ice.

The design of the well-known autonomous buoy bottom bottom station according to patent RU 2344962 C1, January 27, 2009 [1] seems to be the most rational of the known technical solutions and adopted as a prototype.

The buoy [1] for monitoring water areas contains a subsurface and may contain surface modules, and the subsurface module includes a sealed container-case with upper and lower covers, in which a block of electronic modules for measuring and recording equipment, a control unit, an information transmitting and receiving unit, and a block are installed power supply, as well as a block of water parameter meters connected to the block of electronic modules of the measuring and recording equipment, including conductivity and temperature sensors Electrochemical detector of the ion-selective sensors and a pulse detector radiation analysis, housing means coupled to the buoy line and is provided cargo germorazemom.

However, the functionality of the known device [1] is limited, although it can be expanded both in terms of expanding the composition and rational modification of structures, as well as increasing the categories of destination and use.

The essence of the proposed technical solution is to create a buoy for monitoring ice-covered water areas, which has the versatility of a buoy station, which can be used both as an autonomous bottom station (ADS) and a cable bottom station (DSC), as well as when interacting with underwater vehicles ( PA).

The main technical result is an increase in the information content of monitoring parameter measurements while expanding the functionality and arsenal of devices for monitoring water areas through the use of a buoy both in an autonomous version and in a cable connection with surface buoyancy and / or underwater cable. The advantage of the proposed buoy is also the ability to interact with PA and / or cable bottom structures via a radio modem.

The technical result is achieved as follows.

The designations in the drawing are given below.

The buoy for monitoring ice-covered water areas contains subsurface and surface modules 1 and 2, and the subsurface module includes a sealed container-case 3 with upper and lower covers 4 and 5, in which a block of electronic modules for measuring and recording equipment, a control unit, and a block are installed information transmitting and receiving unit and power supply unit, as well as unit 6 of water parameter meters connected to the block of electronic modules of measuring and recording equipment, including conductivity sensors and eratury electrochemical detector of the ion-selective sensors 7 and 8 of the radiation detector pulse analysis. The housing by means of a buirp 9 is connected to the load 10 and is equipped with a pressure seal 11.

A distinctive feature of the buoy is that a platform 12 is mounted on the housing of the subsurface buoy module with a block of water parameter meters installed on it, a current meter 13, the inputs and outputs of which are connected to the inputs and outputs of the block of electronic modules of the measuring equipment. The surface module of the buoy includes a float 15 frozen into the ice cover 14, on which a transceiver block 17 with a radio antenna 18 and satellite communication antenna 19 is fixed to the posts 16. The upper cover of the housing of the subsurface module of the buoy is attached by a cable 20 to the float of the surface module, and the transceiver unit of the surface module is connected via cable 21 to the block of electronic modules of the measuring and recording equipment of the subsurface module of the buoy.

In specific cases of the buoy implementation, a module of the CTD brand (Conductivity, Temperature, Depth) can be used as a block of water parameter meters, including conductivity, temperature and depth sensors.

As a flow velocity meter, a module of the AQUADOPP 3000M model from NORTEK can be used.

As a radio communication antenna, a satellite antenna of the IRIDIUM brand can be used.

The buoy is also characterized in that the container body is provided with upper and lower barriers 22 and 23, mounted respectively on the upper and lower covers of the body.

In addition, the buoy is characterized in that the antenna of the transceiver of the radio modem is additionally installed on the platform, the input-output of which is connected to the input-output of the block of electronic modules of the measuring and recording equipment.

The work of a universal buoy for monitoring water areas covered with ice is as follows.

The buoy consisting of subsurface and surface modules 1 and 2, in the container case 3 of surface module 1 of which there is a block of electronic modules for measuring and recording equipment, a control unit, an information transmitting and receiving unit and a power supply unit (not shown in the drawing), is installed in a predetermined water area. After setting the buoy, measurements of the parameters of the aquatic environment begin: block 6 (which is used as a module of the CTD brand [10]) measures electrical conductivity, temperature and depth, electrochemical monitoring of the aquatic environment is carried out by means of ion-selective sensors 7, and a pulse detector 8 performs radiation analysis. To measure the flow velocity, module 13 of the AQUADOPP model [11] is used. Block 6, sensors 7, detector 8 and module 13 are rationally placed on the platform 12, mounted on the housing 3.

Measurement data are recorded and stored in the block of electronic modules located in the housing 3. The operation of the equipment of the buoy located in the housing-container 3 is controlled by software and computing units, the structure and operation of which are known and are given, for example, in RU 28778 U1, 04/10/2003 , RU 2229146 C1, 05.20.2004, [9].

In the working position, the subsurface module 1 is attached to the load 10 by means of a buirp 9. A float 15 of the surface module 2 is attached to the top cover 4 via a cable 20, on which the transceiver unit 17 is mounted on the posts 16. After setting in a given area, the float 15 is frozen into ice cover 14. The measured parameters of the aquatic environment through the cable 21 are transmitted from the subsurface module 1 to the transceiver unit 17 of the surface module 2 and then through the antennas 18 and 19 - in the air. As the antenna 19, an Iridium + GPS satellite communication antenna can be used [12]. The connector 11 provides cable communication between the subsurface and surface modules 1 and 2.

On the platform 12, an antenna of a radio-modem transceiver (not shown) can be additionally installed, the input-output of which is connected to the input-output of a block of electronic modules of measuring and recording equipment.

The antenna of the radio modem (the structure and operation of which is known, see, for example, [13]) allows receiving commands and transmitting data over the air (up to 5–10 m) without raising the buoy to the surface, for example, exchanging commands and data with an autonomous uninhabited PA (AUV).

To protect against mechanical damage, the container body 3 with the equipment placed on it can be equipped with upper and lower fences 22 and 23, mounted respectively on the upper 4 and lower 5 covers of the housing 3.

Thus, the proposed technical solution expands the arsenal of devices for this purpose by creating a buoy for monitoring ice-covered water areas, which has the versatility of a buoy station, which can be used both as an ADS and a DSC, as well as when interacting with PA underwater vehicles. At the same time, a technical result is achieved - increasing the information content of measurements while expanding the arsenal of devices for this purpose - which is in a causal relationship with the aggregate of essential features of the device.
