Description

[Detailed description of the invention] (Field of industrial application) This invention is a system in which a water sampling container is fixed to a wire capable of transmitting signals using electromagnetic induction and suspended from a ship, and water is collected in accordance with commands from the ship. This relates to a water sampling device that can be commanded on board.

(Prior art) A water sampling container with both ends open has a lid connected to both ends by elastic cords, and both ropes attached to the lid are connected to the water sampling container. A water sampling device in which water is sampled by closing both ends of the water sampling container with the lid by releasing the connection is known, for example, from Japanese Utility Model Publication No. 154/1983.

In the conventional example described above, the trigger mechanism for opening and closing the lid body is mechanically operated, and the trigger mechanism is operated using a messenger that causes the water sampling container to fall along a wire that suspends it. However, even when a water sampling command is issued, it takes time for the messenger to fall down the wire and reach the trigger mechanism, making it particularly unsuitable for water sampling at depths of several thousand meters.

Furthermore, in the conventional technology, when a plurality of water sampling containers are attached to one wire, when the measuring jar of the water sampling container closest to the winch operates, the next measuring jar falls to the lower water sampling container, and so on. Since the structure is such that water is sampled one after another in this manner, if the Messenger does not operate correctly, it will not be possible to sample water in the next water sample container.

It is also known to operate the trigger mechanism electrically, in which a signal cord is used together with a wire that suspends the water sampling container, and the signal cord operates the trigger mechanism. For this reason,
When attaching multiple water sampling containers to the wire, you need as many signal cords as the number of water sampling containers.
Furthermore, when using a cable with a built-in signal cord, it could only be attached to the tip of the cable.

For this reason, there was a problem that water sampling could not be performed by integrating with a measurement sensor installed in the middle of the cable, and furthermore, there was a problem that failures due to water leakage were likely to occur when commands using signal codes in conventional technology were used. .

On the other hand, in the past, many water sampling devices
Since it is often used for CTD and STD salinity tests, it is installed at the bottom of the water sampling container.
CTD etc. are installed in parallel. Therefore, there is a problem in that the combined mounting height is high and the height of the davit is limited when loading or recovering from a ship at sea, resulting in poor operability.

(Problem to be solved by the invention) The problem to be solved by the invention is to solve the problems of the prior art by changing the signal transmission method from the usual electrical connection to the electromagnetic induction method. By using a coated conductor (coating wire), it is possible to attach multiple water sampling containers to arbitrary locations on the wire, and therefore, to provide an onboard command type water sampling device that allows attachment of other measurement sensors. The purpose is to

(Means for solving the problem) The means for solving the problem in this invention are as follows:
