Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a device that accommodates fish and shellfish inside the device to prevent the fish and shellfish from escaping, and also allows the main body of the device to be contracted so that it can be submerged under seawater or conveniently moved. This invention relates to a device for breeding fish and shellfish.

Fish and shellfish harvesting is fluid due to its locality and locality, and it is not possible to constantly provide a fixed amount to the market. Therefore, market prices become unstable, and along with this -
・There is a situation where the demand for vines is decreasing. For this reason, instead of harvesting fish and shellfish as a natural source of g, fisheries are becoming popular, in which breeding is managed and harvested in a planned manner. Aquaculture equipment for managing the mating and rearing of fish and shellfish has been provided in a variety of types and with a variety of structures, but are they sufficient to withstand changes in the culture environment such as ocean pollution and waves? (
There were no devices that could respond to this problem, and development in this area was expected.

The greenhouse diagram shows conventional fish and shellfish farming equipment.
The tank body 1 is formed of a net made of synthetic resin or the like, and the frame 2 is placed on the tank body l at appropriate intervals to maintain the shape of the tank body 1. In this conventional device, a weight 3 is attached to a tank body 1, and the tank body 1 is supported by a float 4 via a rope or the like, and when the support to the float 4 is relaxed, the tank body The structure is such that the tank body 1 can be made to float by sinking the tank body 1 and tightening the support to the float 4. Further, a rope or the like is tied to the lowermost part of the edge frame 2, and by pulling up this rope, the tank body 1 can be contracted.

The float 4 is moored to an anchor 5 on the seabed to prevent it from being washed away.

The configuration of this conventional device can avoid oil pollution near the sea surface, occurrence of red tide, waves, etc. by preventing the tank body l from sinking, and in the case of high temperatures such as a typhoon, The tank body 1 can be contracted and towed, for example, into a breakwater where it is less affected, and has the ability to respond to changes in the aquaculture environment to some extent.

However, in this conventional device, the tank body l is made of synthetic resin.
Because it is made of a net, it is not possible to attach or secure the edge frame 2 (if it is removed, it will not be able to retain its shape, and even if the edge frame 2 can be removed, there is a risk that the tank body 1 will be deformed by ocean currents, etc.). , Weight: If the weight 3 cannot be lifted, it will shrink when the tank body 1 is lowered and will not be able to maintain its shape.

In addition, when JHIIJ's body L is contracted into a snake ILJ shape, small fish may get caught in this snake ++Jrs++, or the mesh on the bellows part may polymerize, causing high water resistance and hindering towing. there were.

In view of the above-mentioned problems with the conventional device, the present invention has a simple structure, easy operations for sinking, contraction, and movement of the tank body, and has excellent functions, and can effectively respond to changes in the aquaculture environment. The purpose of this invention is to provide a fish and shellfish aquaculture device.

The object of the present invention is to consist of a - F section tank body and an upper tank body which can be freely inserted into this lower tank body and whose two parts are supported by a float, both of which are free from seawater etc. F
This is achieved by providing a fish and shellfish aquaculture device characterized in that detachment prevention members for both tank bodies are provided at the upper part of the tank body and at the lower part of the -1 part tank body.

Embodiments of the present invention shown in the drawings will be described in detail below.

The present invention consists of a lower tank body 11 and an upper tank body 12, and both the tank bodies 11 and 12 are made of resin-coated metal wire in a mesh shape so that seawater or fresh water can freely flow in and out and have a certain regularity. is formed. The reason why we use resin liquid FN gold bending wire is that mere metal wire is outdated! (1) This is because it is easy to propagate, so it is easy to form a desired shape, and it is easy to form by adding regularity to the shape. A specific example of this resin-coated metal wire is a vinyl-coated electric wire.
It can be produced extremely cheaply. The certain regularity given to both tank bodies 11.12 means that it will not be deformed by water resistance at least when towing ocean currents, small waves A'J, or both tank bodies 11.12; It doesn't matter if it has the property of being destroyed if strong oppression is applied to it.

The two-part tank body 12 is formed so that it can be inserted into the lower tank body 11, and can be inserted into the outside of the lower tank body 11 as shown in FIG. 2, and conversely, as shown in FIG. of body 11.

Any structure that fits inside may be used.

Further, the number of two-part tank body 12 is not limited to one, but may be plural as shown in FIG. 4.

However, when shrinking the tank, it is desirable that the tank forming the intermediate portion be formed into a cylindrical shape. The top wall of this partial tank body 12 may be left open, but it is preferable to close it with a piece that can be opened and closed with a chunk or the like to prevent the fish from flying away. . Further, as shown in FIG. 5, it is convenient for feeding etc. to provide an auxiliary roller that can open and close only a portion of the top wall.

This upper tank body 12 is supported by a float 4, and appropriate supporting means such as lobes are used. However, when this support means sinks both tank bodies il and +2, which will be described later,
Must be extensible. The float 4 has both tank bodies 1
1.12 has the buoyancy to float near the sea surface,
It is also possible to use waste products such as drums for l/X. Note that this float 4 is moored to an anchor 5 on the seabed.

Separation prevention members 7 for both the tank bodies 11 and 12 are provided at the -1 part of the F-section tank body 11 and at the lower part of the second-section tank body 12. This secondary anti-separation member 7 may be secured with a simple protruding piece, or may be secured with a cylindrical kite 7a as shown in FIG.
The engaging rod 7b is fitted into the axial direction of the kite 7a, and the through groove 7C cut out in the axial direction of the kite 7a is made into an A+'l'+ structure in which the engaging rod 7b can slide. Turn the engaging rod 7b to (
° If the 1X tank body 11 is shot, both the tank bodies If, which will be described later.
, 12 has the advantage of smooth contraction.

The present invention is generally used in the configuration shown by the solid line in FIG. Fish and shellfish are accommodated and raised in both tank bodies 11 and 12. When feeding, the upper tank body 12 is assisted [16
This is done by opening the In this state, both tanks 11.1
2. Since seawater etc. can freely flow in and out, leftovers from feeding and excrement from fish and shellfish flow out to the outside, and the inside is always kept clean. In addition, its shape is maintained and will not be deformed by the force of the Wij flow or small waves.

116 (= 1) In the event of near oil pollution, red tide, or rather large waves, relaxing the supports on the float 4 will allow both tank bodies 11 and 12 to be Both tank bodies 11.+2 sink due to their own weight, and the above-mentioned contamination can be avoided. (See the broken line in Figure 2) When this tank body sinks, both tank bodies 11.12 have a certain fixed shape. Therefore, even if there is no weight 3 like the conventional device, its shape will not change and it will not affect the activities of seafood.In addition, it can be used when harvesting seafood or to avoid high waves such as typhoons. When the lower tank body 11 is to be moved for storage, the lower tank body 11 is pulled up and both tank bodies 11 and 12 are polymerized and contracted.
If both tanks 11 and 12 are small, a pole with a hook attached to the tip may be used, but if they are large, a winding rope 8 is attached to the lower tank II. By hoisting it up using a hoisting machine 9 mounted on the float 4, the bottom tank body 12 can be easily accommodated in the upper tank body. In such a contracted state of both tank bodies 11 and 12, small fish will not be caught between them unlike in the conventional device described above.
Even when the mesh is polymerized, it does not become bellows-like and the flow of 116 water etc. is not obstructed much, and since it is housed in a small size, water resistance does not become large and it can be easily towed. Furthermore, the removal of seafood is extremely easy since there is a ridge at the bottom.

As described above, according to the present invention, the structure is extremely simple, and the tank body can be easily operated for sinking, shrinking, and moving, and its functions are also excellent, and the effect is that it can effectively respond to changes in the aquaculture environment. There is.
