FI100846B - Cash dump for storage and breeding of fish - Google Patents

Abstract

The invention concerns a caisson for keeping and rearing fish. The caisson is made of a net and is supported by a float 5 advantageously of spherical shape on which there is an upper frame 4, advantageously circular, whose inner part is open, and the cover net 1A is secured to the upper frame 4 and the frame 2 and provides a free space for the fish between the cover net 1A and the water surface and the frame 2 which is lighter than water is pressed upwards and possibly floats, and the frame 3 which is heavier than water is pressed downwards and holds the side net 1B between the frames 2 and 3 taut. In the normal position, the float 5 shuts off the opening of the frame 4. On introducing or removing fish or feed, the caisson is lifted by gripping round the frame 4 and the float 5, by means of its weight, remains on the water surface and leaves the opening in the frame 4 free, through which it is possible to remove or introduce fish or feed. When the caisson, secured via a line 7 to the float 5, is lifted back, the opening of the frame 4 is closed by the float 5 and the caisson again becomes a closed structure. <IMAGE>

POSITION FOR STORAGE AND BREEDING OF FISH

The present invention relates to a cash sump ie. a fish sump suitable for storage and breeding of fish.

The sumps that are nowadays used in private farming are not suitable for breeding fish because the taste of the fish's meat after a long period of time in the sump changes to the worse and gets a bad taste. The sumps are usually made by the fisherman himself and the material is usually wood, metal nets that form an enclosure or container and if the sump is made of a net, the worms are so small that the fishermen cannot accommodate. These sumps are normally intended for short-term storage as long-term storage causes the fish meat to taste. One reason for the off-flavor in the fish meat is considered to be that the sump is too close to the bottom, where from the bottom sludge, debris and other contaminants enter the fish organism. It is of great importance in view of the well-being of the fish, especially in fish of the salmon genus, that the fish can stay at the water surface and take so-called. air bath, ie can jump at a free water surface.

Also a number of liquid cash pumps are known.

Swedish patent specification 458088 discloses a fish breeding device which resembles the present invention with an upper floating frame and a lower heavier frame and with a free space above the water surface. However, it does not have a solution with a float that pours up the roof grid. and which simultaneously closes the opening in the upper frame through which fish can be removed and inserted and thus differ from the present invention.

1 In Finnish patent application 872172, a device for cultivating fish * 'is described where the whole device is supported by pontoons in a polygonal form.

Inside the device itself are one or more catfishes where the fishermen are located.

···; The free space above the water surface is provided by a stand, supported on the pontoons, which tapers up and on which a rotated surface is placed. and thus differs from the present invention. The system is complicated.

• · · • · · · · ·. Norwegian patent 166751 describes a floating fish breeding device which has a bottom that tapers down the net and a nettle in the bottom part of the bottom of the device and the main task of the net strainer is to collect dead bodies. fish from the bottom of the device and it can then be lifted using one or more draw lines.

In U.S. Pat. No. 4,615,301, a floating fish breeding device is described with a heavier lower frame and a floating upper frame, which consists of several elastic tube or hose parts joined at their ends, corners, with coupling devices and corners in turn joined with tensioned wires. outside the device.

U.S. Patent 5477813 and Norwegian Patent No. 173481 disclose a fish breeding and storage facility. It is anchored to the bottom and the structure itself is provided with floats around its periphery which is below the water surface and which has the task of keeping the sump structure stretched out. In the center is a floating center portion provided with a dome structure and joined by a conically shaped network to the peripheral part of the sump located below the water surface. This construction, in particular, is rather complicated and expensive on a smaller scale. Also, picking up fish is difficult.

Finnish pattern application 302/80 and 556/80 (variant) show a floating rectangular net pool where the upper rectangular frame floats. The free space above the water surface is provided by some metal cups which prevent the net from lying on the surface. The figure does not show how the fox is inserted or removed.

•, ·. In Norwegian patent specification 132711, a liquid sump for breeding fish is described and constructed as an umbrella or ekrama in a wheel and the * ekrams in the middle are connected to each other and are located above the water surface and «♦ · '****' at their outer ends. floats are placed outside the sump itself which causes the whole: device to flow. The design with the many floats and the ekrams is complicated.

British patent specification 1516483 describes a device for growing fish. A net bag that takes the form of several rings or frames * then hangs in a rope or the like. It does not float and if you want to get an airspace space for the fishermen, the suspension must be adjusted according to the water level.

• · · • · 1 • · · • · 3 100846

British Patent Specification 1515253 also discloses a similar hanging fish sump made of nets as in the above related British patent specification.

British Patent Specification 0202730 describes an elongated fish sump of nets with a number of rings. Closing and opening is done so that the two last rings are brought close together and rotated in relation to each other, whereby the network is interconnected and one can then read the two rings in that position in each other.

The Norwegian patent specification 162693 discloses a suspension principle for liquid flexible containers e.g. for fish farming. A floating ring runs on the outer side of the container itself and in this, ropes are attached to the bottom of the vessel. Also the container itself has floats along the periphery. This construction can reportedly perform well in road walls, storms etc. Since the container is open, it just cannot be applied in smaller formats because the fish can jump over the edge or the birds can take the fish.

Finnish patent application 3012/65 describes a fish breeding device consisting of a frame of metal pipes. The device is poured fluid by means of floats which are threaded onto the home pillars and which are adjustable. The metal pipes are relatively expensive and can easily rust. Here, the free space above the water surface is provided in a different way than in the present invention.

In all of the above-referenced patents, the opening and closing of the device is a problem. The object of the present invention is to; . ·. remedy the aforementioned shortcomings and inconveniences. This can be achieved by] [· the cassump being made of nets and provided with an upper frame which may be • floating and a lower frame as weight and a float that pours up the roof net so that the fish, regardless of the water level, always has the same free air space and can stay at the water surface and take so-called if needed "Air bath". At the top is a small '*: · * frame where the net is attached. The inner part of the frame is open and this opening is in • * · v; normal position blocked by the float, but if the box is lifted, you can put fish or feed through the opening in the frame or remove fish from the sump.

The features of the present invention emerge from the claims.

An embodiment of this invention is shown in Figs. 1, 2, 3 and 4. Fig. 1 shows the invention seen from the side and Fig. 2 shows the top view. Fig. 3 shows an opening in the roof grid in the closed state and Fig. 4 the same in the opened state.

♦ • · 4 100846

The invention consists of a mesh (1) with roof (1A), sides (1B) and bottom (1C) and this is fixed in three frames (2), (3) and (4). The frame (2) has a specific weight that is lower than the water and is therefore affected by an upright force or float, while the frame (3) has a specific weight that is higher than the water and acts as a weight and ensures that the side net (1B) is stretched . The roof net (1A) is attached to a frame (4) advantageously circular and leaves the inner part, the opening, of the frame (4) without mesh and has a diameter slightly smaller than the float (5) which is advantageously spherical. The length of the roof net, ie the distance between frame (2) and (4) is so adapted that it is tensioned and the lifting force of the float (5), the design of the roof net (1A) and the weight of the sump is so chosen that the roof net is also stretched and the frame (4). ) presses the float (5) into the water so that the float closes to the opening in the frame (4). In the fastening means (6) of the float (5), a line (7) or the like is attached, the other end of which can be fixed to land or to a bridge. Another line (8) is attached at one end to the bottom mesh (1C) or lower frame (3) and carried up through the roof mesh (1A) or top frame (4) and at its other end is attached to any suitable part such as .ex. The inlet (7), the float (5) or the top frame (4) and

The line (8) hangs between its attachment points and in connection with the withdrawal of fish or the regulation of the cassava volume, the line (8) can be easily grasped. In normal mode, the net (1A), (1B) and (1C), as well as the float (5) which closes to the opening (4) form a closed space that prevents the fish from escaping. If necessary, the device can be anchored in the bottom by means of a rope (9) and anchor device (10). The float (5) presses through the frame (4) up the roof net (1 A) above the water surface so that it is poured stretched and allows the fishermen to stay at the surface and do so.

»· ♦ | I · · VJ.m When removing, emptying and filling the cassette or feed, grasp the frame (4) and lift the casket with the float (5) remaining on the water surface leaving the opening in the frame (4) open. When removing fish, you can * * ···: lift up the bottom net (1C) and / or lower frame (3) by pulling in line (8) • # · v: where the cassump's volume decreases and the catching of fish is facilitated .

If the fish are fed with the fishing trip, it is important to have an easily accessible opening, j * \. by which you can bring the fishing trip into the cassava. Otherwise, e.g. if you try to drop them through the roof net (1 A), they can get stuck there and start to rot and spread unpleasant odors around or invite birds to eat them and these can with their feces spread diseases among the fish. By: ··· 'this opening you can then take out fish, bring fish or food there. As one lifts the cassump back into the lake by lifting in Iinan (7), the float (5) tiles into the opening in the frame (4) and closes this opening. By shortening the line (8), the cash pump volume can be adjusted if necessary.

The roof grid (1A) can be divided into a suitable number of parts e.g. in two (1A1) and (1A2) shown in ftg 3 and 4 and the frame (4) in two parts (4A) and (4B) and the rods (11A), (11B), (12A) and (12B) as at one end has a loosely articulated structure around the upper frame (2) and the rods (11A) and (11B) as well as (12A) and (12B) are interconnected at the frame (2) and in their at the other end they are joined to the frame halves (4A) and (4B). One of the grid networks half (1A1) is bounded by and fixed in the parts (2), (11A), (4A) and (12A), the other grid network half (1A2) is bounded by and fixed in the parts (2), (11B) , (4B) and (12B). A suitable reading device (13) e.g. a reading hook that is held in place by e.g. a quartz circular bar (14) which is conveniently attached to e.g. part (11B) and / or (4B) and which sees to it that the roof network parts (1A1) and (1A2) are joined together and that the parts (11A), (11B) and (12A), (12B) along their entire length lie close together that the fish cannot come out between them. At the opening of the cassump, it is lifted, whereby the opening of the frame (4) becomes free and the reading device (13) is opened, after which the frame halves (4A) and (4B) are gripped and pulled sideways and a longitudinal opening in the roof net (1A) rises and the fish can be charged e.g. with raise or by hand. At the end of the roof grid (1A), the roof halves (1A1) and (1A2) are pressed together so that the reading device (13) can be closed.

The above solution is only one example of an embodiment of. invention. The present invention can be carried out in a variety of ways and from a variety of materials. The upper frame can have a much lower specific weight than water and such volume that it carries the cassava and therefore floats. The upper frame (2) may also have a higher specific weight than water and constitute a spacer made of e.g. metal tree where the float (5) takes care that the sump M * flows. Frames (2) and (4) may be joined to a structure that • * · V: enlarges the space between the roof grid (1A) and the water surface, e.g. a suitable number of bars supporting the roof net (1A) to achieve a desired shape e.g.

j \. a dome or the like. Furthermore, the lower frame (3) can be replaced with the sink: '·': e.g. a weighted tree reminiscent of the tine that is common at the lower *, ·. part in fishing nets. The upper frame (2) ensures that the desired device of the device; / form is retained, saving costs. The frames (2) and / or (3) may have circular, rectangular or any other suitable shape and may advantageously be made of tubes e.g. plastic pipes or the like, especially if it is required that the frame must be of less specific weight than the water. An feeding apparatus advantageously a pendulum feeding device for fish can be coupled to the float (5) or the feeding apparatus can, if necessary, be designed as a float and replace the float (5). The frame (4) is adapted to have a similar shape to the float (5) or the feeding apparatus in cross section. The nets (1A), (1B) and (1C) can all be one or more nets that are joined together and if the roof net (1A) is a ski It net, this is advantageously provided with as large meshes as possible so as not to feed fish. thrown to the fish from above etc get stuck there and start to rot and spread unpleasant odors around or invite birds to end up eating them and with their stools they can create diseases among the fish. The frame (4) can advantageously be made of an elastic material and formed into a ring which can be opened and closed or its diameter can be adjusted if necessary and so that its length in the straightened position is considerably longer than the circumference of the finished frame (4) ie the ends pass each other and these are provided with a reading device such that an annular frame (4) is formed and the net is cut, if necessary, between the frames (2) and (3) in the position where the frame (2) is open but the ends of the roof net (1A) like each other and the roof grid (1A) closes when the frame (4) closes and when the frame (4) is opened, the opening becomes considerably larger than the opening in the closed frame (4) and if the roof grid (1A) has been snooped around the frame (4) it also opens up that if necessary you can enter the box with a lever or close the inside of the box to carry out undercovers etc.
