Description

Изобретение относитс к устройствам дл автоматического отбора проб воды на .заданных глубинах в процессе непрерывного зондировани и может быть применено при изучении вертикальных гицрологических разрезов.The invention relates to devices for the automatic sampling of water at predetermined depths in the process of continuous sounding and can be applied in the study of vertical hyzrological incisions.

Известно устройство дл автоматического отбора проб воды на заданных глубинах , содержащее надводный блок управлени , состо ишй из блока формировани управл кнцих сигналов, блока цифровой индикации глубины погружени и элемента св зи, погружаемый герметичный котейнер с элементом св зи, блоком приема управл ющих сигналов и датчиков давлени , прюбоотборники и механизмы закрывани их крышек ij .A device for automatically sampling water at predetermined depths is known, comprising a surface control unit consisting of a control signal generation unit, a digital depth indication digital indication unit and a communication element, a submersible sealed container with a communication element, a control signal receiving unit and sensors pressures, vacuum collectors and mechanisms for closing their covers ij.

Недостатком известного устройства вл етс невысока надежность в случае дискретного измерени глубины, а при зондировании с переменной скоростью и частотой опроса могут возникнуть ложные срабатыва ш или пропуски глубины срабатывани пробоотборников.A disadvantage of the known device is low reliability in the case of discrete depth measurement, and when probing with a variable speed and a sampling frequency, false triggers or omissions of the sampling depth can occur.

Цель изобретени - повысить надежность работы устроГгства.The purpose of the invention is to improve the reliability of the operation of the device.

Это достигаетс тем, что в надводный блок управлени введены блок вьгбора зоны и блок исходных данных, выхоа которого соединен с первым входом блока выбора зоны, второй вход которого соеаинен с выходом блока цифровой индикации глубины погружени , а выход блока выбора зоны соединен с входом блока формировани управл ющего сигнала.This is achieved by introducing a zone selection block and initial data block into the surface control unit, the output of which is connected to the first input of the zone selection unit, the second input of which is connected to the output of the digital display unit of the immersion depth, and the output of the zone selection unit control signal.

Claims

The device consists of a surface control unit 1 with a source data unit 2, a zone selection unit 3, a digital indication unit of the immersion depth 4, a control signal generation unit 5 and a communication element 6, a submersible sealed container 7 with a pressure sensor 8, a communication element 9 , by the control signal receiving unit 10, the sampler 11 and the mechanism for closing the sampler lids 12. The device works as follows. The information received from pressure sensor 8 via communication elements 6 and 9 is recorded in digital block 4 of display 4 and compared to zone select block 3. In this block, the received code is compared with predetermined initial sampling response levels, and the comparison error depends on the level Signals received from block 2 of the original data. According to the results of the comparison, the zone selection unit 3 outputs a single permitting signal to the control signal shaping unit 5 and at the same time prohibits the re-enabling signals until the sealed container is moved to the depth equal to the next decryption zone. The width of the zone for generating a control signal must be, on the one hand, minimal, in order to ensure that the sampling probe can work close to the required depth, and at the same time the zone must be wide enough so that under the conditions of waves at a given container immersion speed 7 and the sampling frequency of sensor 8 was provided with measuring at least one depth value in the zone. From the forming unit 5, the control signal is fed through the communication elements 6 and 9 to the receiving unit 1O of the control signal of the sealed container 7 and through the mechanism 12 for closing the pilot lights 11 to trigger the next sampler. The pressure sensor 8 with a given polling frequency continues to provide depth information to the digital display unit 4, and when the container 7 is moved to the next zone, the next sampler is triggered. The invention A device for automatic water sampling at predetermined depths, comprising a surface control unit consisting of a control signal generation unit, a digital display unit of the immersion depth and a communication element, a submersible sealed container with a communication element, a control signal unit and a pressure sensor, samplers and mechanisms for closing their covers, characterized in that, in order to increase the reliability of the device, a zone selection unit and an initial unit are inserted into the surface control unit This data output is connected to the first input of the zone selection unit, the second input of which is connected to the output of the digital display unit of the immersion depth, and the output (the zone selection unit is connected to the input of the control signal generating unit.
