Description

[Detailed explanation of the invention] (a) Industrial application field This invention relates to a spherical pressure-resistant vessel that is dropped onto the seabed and contains measuring equipment such as a seismometer and magnetometer.

(b) Conventional technology For example, in order to detect magnetic changes on the ocean floor, a magnetometer is housed in a splittable spherical pressure-resistant glass container and dropped onto the ocean floor (for example,
No. 20937).

However, this spherical pressure-resistant glass container is unexpectedly heavy and, together with its spherical shape, is difficult to handle.Moreover, the container that is normally dropped onto the ocean floor is divided into two parts called a hard hat, as shown in Figure 2. They are stored in protective containers 1, 1a, and 1b, so after completing the measurement and recovering them from the seabed, remove this protective container 1a (one half of the hemisphere) and find the spherical containers 2, 2a, and 2b buried inside. It was difficult and dangerous to remove the sample due to the weight of the measuring equipment contained therein. For this reason,
I used to put the protective container on its side and take it out, but there was a risk of damaging the glass container.

(c) Purpose This invention was devised in view of the above-mentioned conventional problems, and the purpose is to provide a spherical pressure-resistant container that is easy to transport and handle.

(d) Configuration The spherical pressure-resistant container of this invention has a structure in which its outer periphery is wrapped with a net. Therefore, the net prevents the hand from slipping and the fingers can be caught on the net, making it easy to transport and handle.

(e) Embodiment Figure 1 shows an embodiment of the spherical pressure vessel of this invention. Figure A shows the state of use in which the protective containers 1, 1a, and 1b are divided into two parts and are dropped onto the seabed, while Figure B shows the spherical pressure-resistant containers 2, 2a, and 2b inside after the measurements have been completed and the containers have been recovered from the seabed. Protective container 1 to take out
The figure shows the state in which a (one half of the hemisphere) has been removed.

The spherical pressure-resistant container 2 is usually made up of two hemispherical containers 2a and 2b joined together, and the joint is sealed with a sealing tape 3 and tightened with a fastening pad 4. The outer periphery of the spherical pressure-resistant container 2 of this invention is wrapped in a net 5 made of woven thin strings. The close contact of the net 5 to the outer periphery of the container is adjusted using a drawstring 6.

Incidentally, it goes without saying that the spherical pressure-resistant container 2 whose outer periphery is wrapped with a net can be fully accommodated in the conventional protective container 1.

(f) Effects The spherical pressure-resistant container of this invention is easy to carry because the net prevents the hand from slipping, and it is also easy to store and take out the container by placing one's fingers on the net. This has the effect of softening the impact on the container.
