Description

An underwater sample dry-wet conversion and transfer device

technical field

The invention relates to the technical field of underwater sample transfer, in particular to a device for dry-wet conversion and transfer of underwater samples, specifically for transferring the underwater samples obtained by the underwater sampler to the manned cabin of the submersible for real-time analysis The underwater sample dry-wet conversion and transfer device.

Background technique

At present, all kinds of underwater samples obtained by underwater manned submersibles or unmanned submersibles must be brought back to the surface ship by the submersible before they can be analyzed and tested. That is, after the submersible takes samples, it must float to the surface of the water to take out the underwater samples. After the sample is tested and tested, if it is necessary to re-sample the sample at the same location, the submersible needs to carry the sampling equipment again to carry out the dive operation again, dive to the original sampling location for re-sampling, and then float to the surface Send the sample taken to the surface ship. In this process, the submersible’s ascent and dive process takes up a large part of the operating time. As the water depth increases, the submersible’s ascent and descent time also increases greatly. The efficiency of the entire sampling operation is greatly reduced. Therefore, test and testing equipment are installed in the manned cabin of the manned submersible, and the underwater samples obtained by the underwater submersible are directly sent into the manned cabin through the dry-wet conversion and transfer device for analysis, testing and testing. The real-time adjustment of the underwater sampling operation by the test analysis results can effectively reduce the time spent on the submersible's floating and diving, and greatly improve the efficiency of the sampling operation.

detailed description

The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

As shown in Figures 1 and 2, the dry-wet conversion and transfer device for underwater samples of this embodiment includes a manned cabin 11, and a dry-wet conversion and transfer device 12 is installed at one end of the manned cabin 11, and a dry-wet conversion and transfer device 12 is installed. The structure of the device 12 is as follows: including a conversion cabin cylinder body 1, a conversion cabin hatch cover 2 is respectively installed at both ends of the conversion cabin cylinder body 1, a slide rail 5 is installed on the inner wall of the conversion cabin cylinder body 1, and a sample is placed on the slide rail 5. Rack 6, the sampling tube 4 is placed on the sample rack 6; a vent valve 3 is installed on the conversion cabin hatch cover 2 at one end, and an air release valve 9 is installed on the conversion cabin hatch cover 2 located at the other end. A pressure gauge 8 is installed on the top of the cabin cylinder body 1, the top of the conversion cabin cylinder body 1 is connected to the air pump 7 in the manned cabin 11, and the bottom of the conversion cabin cylinder body 1 is connected to the water pump 10 in the manned cabin 11.

The cylinder body 1 of the conversion cabin adopts a split structure.

The process of dry-wet conversion and transfer of samples is as follows:

The ROV uses the sampling cylinder 4 to carry out underwater sampling, and then sails to the vicinity of the sample dry-wet conversion and transfer device 12. The conversion cabin is filled with normal pressure water in advance. The vent valve 3 is opened to change the environment in the conversion cabin from a wet atmospheric pressure environment to an underwater environment, and then the hatch cover on the side of the underwater environment is opened, and the ROV uses a manipulator to pull the sample rack 6 out of the conversion cabin cylinder 1 , and then put the sampler with the underwater sample on the sample rack 6. After the sample is placed, the ROV uses the manipulator to push the sample rack 6 back into the conversion cabin cylinder 1. The underwater environment side The hatch is closed, and at this moment, the conversion cabin is an underwater environment. Start the water pump 10 in the manned cabin 11, pump the water in the conversion cabin to the underwater environment, open the air pump 7 in the manned cabin 11 at the same time, fill the conversion cabin with air, and use the pressure gauge 8 to convert The pressure in the cabin is monitored, and when the water in the conversion cabin is all drained, the water pump 10 and the air pump 7 are closed, and the pressure in the conversion cabin is regulated by the air release valve 9 to make it become normal pressure. The conversion cabin completes the conversion from the underwater wet pressure environment to the dry normal pressure environment. After the dry-wet conversion of the conversion cabin is completed, the hatch cover on one side of the manned cabin 11 is opened, and the personnel in the cabin pull the sample rack 6 out of the conversion cabin cylinder 1, and pull the sampling cylinder 4 out of the sample rack. 6, the real-time monitoring and analysis of the samples in the sampler are carried out in the cabin.

The underwater sample dry-wet conversion and transfer device designed by the present invention is compact in structure and easy to operate, and is suitable for sending the underwater sample taken by ROV under a certain water depth into the manned cabin 11 of the manned submersible for analysis and testing in time, which is helpful Adjust the sampling operation in real time after the test analysis of the sample, or operate the ROV to perform fixed-point repeated sampling, which saves the time spent on the surface of the submersible and the submersible that is usually used at this stage to send the sample back to the surface ship for analysis and testing. , improving work efficiency.
