(産業上の利用分野)
本考案は、海底のマンガン団塊、各種の海中質
源等の採取に適用される海中用採取管に関するも
のである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an underwater collection tube that is applied to collecting manganese nodules on the seabed, various underwater sources, etc.

操作装置等が大規模になつている。(Conventional technology) To extract manganese nodules from the deep seabed, a long collection pipe is guided deep into the sea from a mineral collection vessel, and the manganese nodules from the deep seabed are sucked up from the lower end of the collection pipe and transported onto the ship. This is done by retrieving the equipment,
Since the collection tube is long and heavy, the weight has to be increased to ensure the strength of the collection tube and its support.
Operating devices, etc. are becoming larger in scale.

があるなどの問題点がある。(Problems to be solved by the invention) In the conventional underwater sampling tube, as the sampling point becomes deeper under the sea, the sampling tube becomes longer and heavier.
Increasing the thickness of the tube wall (thicker at the top) to ensure the strength of the sampling tube adds additional weight, making the support and operation equipment for the sampling tube significantly larger, and making deep-sea sampling difficult. This causes a decrease in work efficiency, and there are problems such as a limit to the sampling depth.

が増大されている。 The collection tube becomes longer as the sampling point becomes deeper, and the weight of the collection tube itself increases. Since the strength was ensured, the weight of the collection tube was added, making it difficult to support and operate the entire collection tube.However, in the present invention, appropriate lengthwise intervals are added to the outer periphery of the collection tube 2. Hollow donut shape 3 or hollow honeycomb shape 6
Since the buoyancy device is provided, the underwater weight of the sampling tube 2 is significantly reduced by the buoyancy device, the supporting force of the sampling tube is significantly reduced, and the operation is facilitated. The buoyancy devices installed on the outer periphery of the collection tube 2 are appropriately installed in terms of number, installation interval, and buoyancy force depending on the length of the collection tube and the attachment position. is being increased.

化が可能になつている。 The weight of the sampling tube 2 in the sea is significantly reduced by the buoyancy device, so the weight of the sampling tube itself can be reduced, and there is almost no need to increase the thickness of the upper part, resulting in a significant reduction in weight. At the same time, it is possible to increase the depth of the sampling point by reducing the supporting force of the entire sampling tube, making it easier to operate, and reducing the size of the sampling tube.
It has become possible to downsize the entire collection pipe support, operating device, and mineral extraction vessel.
