- the selective blocking assembly of the second tube 34 will be described here. This blocking assembly is also present on all tubes 32 to 37 and will not be described for the other tubes.
- a locking rod 1 14 deployable radially relative to the second tube 34, an actuating hook 1 16, intended to cooperate with the third tube 32, a yoke 1 18 connecting, and a push rod 120, connecting the connecting yoke 1 18 to the locking rod 1 14.

- the yoke 1 18 carries the hook 1 16. It links the hook 1 16 to the push rod 120. It is rotatably mounted on the upper end of the second tube 34.
- the yoke 1 18 and the rod 120 follow the movement of the hook 1 16. They rise when the hook 1 16 moves to its upper position and descend when the hook 1 16 moves to its lower position.
- the connecting rod 120 pushes the rod 1 14 radially outwards and blocks the rod 1 14 in the retaining groove 41 of the first tube 36.
- the line 26 of the sampling assembly 18 occupies its retracted storage configuration, being totally received in the well 22 of the shell 20.
- the tubes 30 to 36 are received concentrically in the upper tube 38.
- the upper ends of the tubes 30 to 38 are arranged in the vicinity of each other.
- the locking system 29 is deactivated, each hook 1 16 of a given tube 32 to 37 being pushed into its upper position by the flange 42 of a tube 30 to 36 located below the given tube 32 to 37.
- the length of line 26 along the AA 'axis is minimal.
- Each upper abutment 43A of a tube 32 to 38 is supported on the upper flange 43B of a tube 30 to 37 located inside the tube 32 to 38.
- At least the lower tube 30 is held vertically in the structure 14 by means of a locking system (not shown) which prevents the deployment of the tubes 30 to 37.
- the shuttle 60 When water must be withdrawn, the shuttle 60 is lowered into the lower tube 30, with its stops 76 in the retracted position as shown in FIG. 6. During this descent, the support member 80 rests on the wall cylindrical 72 of the insertion member 64. The inner finger 84 occupies its upper position above the outer finger 92, as shown in Figure 7.
- the lower tube 30 is released from the structure 14 and then rests under the effect of its weight on the shuttle 60, by pressing the lower flange 66 of the sleeve 46 on the stops 76. It thus takes up the weight of the assembly tubes 32 to 37.
- the hoist 62 is then maneuvered to gradually lower the lower tube 30, together with the tubes 32 to 37 relative to the upper tube 38.
- the liner 46 then descends along the sleeve 48 causing the vertical translation of the lugs 52 in the through passages 50, and the corresponding lowering of the connecting rod 1 12, as can be seen in FIG.
- the blocking projection 1 10 then extends radially in the retaining groove 41 of the tube 32.
- the insertion member 64 of the shuttle 60 continues to descend relative to the support member 80, which abuts on the sleeve 46.
- the shuttle 60 is then raised using the hoist 62.
- the water sampling can then be performed, as shown in Figure 5.
- Line 26 then has a maximum length along axis A-A 'under structure 14.
- the insertion member 64 enters the insertion passage 54 and the support member 80 abuts against the upper edge of the sleeve 46.
- the shuttle 60 is raised.
- the radial stops 76 being deployed radially, they rest under the lower collar 66, which has the effect of raising the sleeve 46 relative to the sleeve 48.
- Pulling up the sleeve 46 by the insertion member 64 causes its rise relative to the sleeve 48, and the retraction of the locking projections 1 10.
- the lower tube 30 then rises in the tube 32 located just above, without any of the other tubes 32 to 37 goes back, thanks the deployment of the locking rods 1 14 engaged in the corresponding retaining grooves 41.
- the upper end of the tube 32 approaches the upper end of the tube 34, it pushes up the hook 1 16, releasing the locking rod 1 14 of the tube 34 in the tube 36, as visible on the figure 13.
- the tube 34 can then go up together with the tube 32 relative to the tube 36.
- the rise of the other tubes 36, 37 is performed in a similar manner.
- the sampling assembly 18 is therefore particularly simple to handle, since it deploys telescopically and retracts very easily, without the need to perform complex assembly operations tubes.
- the sampling assembly 18 thus allows a safer operation, especially in case of evacuation of the structure 14, but nevertheless very fast to put back into production.
- the selective cooperation mechanism 65 between the shuttle 60 and the lower tube 30 provides a very effective coupling of the shuttle 60, while being perfectly reversible. This increases the reliability of use.
- the operating device 28 comprising a shuttle 60 releasable from each line 26, it is possible to successively deploy each line 26 using the same shuttle 60. This limits the size on the structure 14, since a single device maneuver 28 can be used for several lines 26.
- the line 26 is adapted to be deployed in a partial deployment configuration between the retracted configuration and the deployed configuration.
- the holding mechanism is adapted to retain in the shell 20 an intermediate tube 32 to 37 between the lower tube 30 and the upper tube 38. All the tubes located in the intermediate tube are able to deploy jointly with the lower tube 30, while all the tubes receiving the intermediate tube remain retained in the shell 20.
- the holding mechanism comprises a lower tube retaining cable 30 of fixed length, preventing the deployment of all the tubes of the line 26, once the shuttle 60 removed from the lower tube 30.
- the retaining cable is put in place before the deployment of the line 26.
- a dispensing line of a water treatment product is lowered into the line 26 to open into the strainer 44 of the lower tube 30.
- the treatment product is for example a corrosion inhibitor and / or a microorganism development inhibitor, comprising for example a hydrochlorate.
- the shuttle 60 is adapted to engage reversibly and selectively on each water withdrawal line 26 and to free itself from each water withdrawal line 26, both in the retracted configuration and in the retracted configuration. in the expanded water sampling configuration.
- the shuttle 60 is thus adapted to engage reversibly with a lower tube 30 of the water withdrawal line 26 in the retracted configuration, via the mechanism 65, to allow a first descent of the shuttle 60 and from the lower tube 30 to the water sampling configuration.
- the shuttle 60 is then able to free itself from the water sampling line 26 to be raised to the surface, the water sampling line 26 remaining in its water sampling configuration.
- the shuttle 60 is adapted to reverberably engage the lower tube 30 of the water withdrawal line 26 again in the configuration of water withdrawal, through the mechanism 65, to allow a rise of the shuttle 60 and the lower tube 30 to the retracted configuration.
- the fluid treatment unit 16 is a unit for converting thermal energy of the seas ("Ocean Thermal Energy Conversion" or "OTEC").
- OTEC Ocean Thermal Energy Conversion
- the water pumped into the water sampling line 26 is intended to cool a working fluid in an energy conversion cycle, this fluid being directly from the water pumped on the surface and / or an intermediate fluid heated by water pumped on the surface.
