Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for cultivating marine life, particularly pelagic life, and in particular fish, with which it is attached.

This type of aquaculture device is covered by French Patent Application No. 77-1! ;220
Known by No.

According to this French patent application, the inflatable enclosures are arranged in layers from above to below the buoy shaft.

This device has the following disadvantages.

That is, this device requires a buoy shaft of considerable height and can only be installed in waters of sufficient depth. Furthermore, when aquaculture equipment is installed in a sea area where tidal currents are common, the spacing between the equipment must be set sufficiently large so that the equipment can be rotated so that the enclosure is on the downstream side in the direction of the tidal current. No.

SUMMARY OF THE INVENTION An object of the present invention is to provide an aquaculture device that is configured to be well adapted to the conditions of a sea area with insufficient depth or a sea area with changing tidal currents.

This object, according to the present invention, is an apparatus for cultivating floating buoy-bearing organisms, especially fish, in which the enclosures are arranged in substantially the same plane and distributed around the buoy axis; This is achieved by an aquaculture device characterized in that the buoy shaft is connected to the buoy shaft by arms and a reservoir conduit for circulating water is arranged in the arms.

Due to the coplanarity of the enclosure, the draft of the aquaculture device is considerably reduced. Furthermore, by distributing the enclosures around the buoy axis, the aquaculture device is approximately symmetrical about the buoy axis and does not change direction due to the current flow.

According to a preferred embodiment of the invention, the enclosure has a circular planar shape and is connected to the connecting arm approximately in the middle.

In that case, the water supply to the enclosure takes place tangentially to the outer circumference.

The shape of the enclosure is preferably a torus, with water flowing out from the center.

Preferred embodiments of the invention shown in the drawings will now be described in more detail.

The aquaculture device shown in Fig. 11 has a buoy shaft l (buoy shaft), on the top of which can be installed a technology and accommodation unit 2, and in the center of the buoy shaft is a buoy shaft for marine life. Reservoirs 8 can be provided for feed, drinking water, fuel, buoyancy parast, etc. There is a weight 4 at the bottom of the buoy shaft 1.
is not installed.

According to the embodiment shown, the buoy has three aquaculture enclosures 5, which may be of the type described below with respect to FIG. The shafts are arranged at equal intervals around the shaft, and are connected to the shaft by a connecting arm 6.
Ru.

The buoy shaft 1 may of course be connected to a mooring device.

The expandable aquaculture enclosure 5 shown in FIG.
Made from a synthetic material that is water resistant and capable of withstanding the marine environment and mechanical forces generated by pressure, ocean currents and swells.

The enclosure 5 is generally torus-shaped and is connected to the buoy shaft l by a connecting arm 6, as described above. The connecting arm 6 is connected to the central part of the enclosure 5.

The connecting arm has two conduits for circulating water, namely an inflow pipe 7 and an outflow pipe 8, which are coaxial in the tip region where they are joined with the enclosure 5, and which are connected to the inflow pipe 7 and the outflow pipe 8, respectively. are arranged around the outflow pipe 8.

The inflow pipe 7 opens into an annular distribution chamber 9 formed in the lower part of the enclosure 5 around the central hole. The two feed pipes 10 extend from the distribution chamber 9 toward the periphery of the enclosure 5 and open into the interior of the enclosure 5 with a nozzle 1l. The water supply to the enclosure 5 by the nozzle 11 is preferably carried out by the enclosure 5.
is carried out tangentially to.

The center of the enclosure 5 is closed by a cylindrical lattice body l2 whose through-hole width can be adjusted. The grid body 12 can be, for example, in the form of a directional shutter.

The cylindrical lattice body l2 receives the outflow pipe 8 at its lower part and is provided with a flap valve 18 at its upper part.

Additionally, a locking device is arranged between the connecting arm 6 and the enclosure 5, and a dart valve 15 is arranged in the outflow pipe 8 near the connection with the cylindrical grid body l2. Ru.

During normal operation, water, to which feed has been added as necessary, is supplied from the buoy shaft l through the inlet pipe 7.

In that case, the grid body 12 is adjusted so that its through holes are insufficiently large to allow the fish to pass through, and the dart valve 15
The Hamura valve 18 is closed to prevent water from returning towards the buoy axis l, and the Hamura valve 18 is opened to drain the used water.

When it is desired to collect fish, the holes in the grid body 12 are enlarged, the Hamura valve 18 is closed, and the gate valve 15 is opened. Owing to the water flow created by the negative pressure established in the outflow pipe 8, the fish pass through the grate 12 and then through the outflow pipe 8 towards the buoy shaft 1, where they are collected.

The present invention is not limited to the specific embodiments described above, but may be configured in various ways within the scope of the present invention.
