Abstract

FIELD: fishing.

SUBSTANCE: fish cage includes a mesh bag and transverse rigid hoops. At least one hoop is made in the form of a convex closed polygon having equal sides, consisting of tubes of different diameters, interconnected by a telescopic method. The end of the tube of the smallest diameter of one side is pivotally fixed at the beginning of the tube of the largest diameter of the adjacent side, forming corners.

EFFECT: invention provides changing the size of the hoop, which changes the size of the transition between sections of the cage, separating large and small fish.

Description

The fish tank is presented in the invention, which can be attributed to the technical solutions used for fishing and storing fish.

Caught fish is stored in a cage in the form of a bag made of netting. For better safety of the fish, the tank has transverse rigid hoops dividing the inner space of the bag into sections. Caught fish tend to be of different sizes, so hoops of different diameters are often used in cages, which affects the size of the transition between sections of the cage to separate large and small fish.

The objective of the invention is to provide the possibility of both reducing and increasing the geometric dimensions of the fish tank hoop.

The document [1] discloses a technical solution that provides for changing the size of the cage inlet with the help of a special spring rod. A description of the cage is given in [2], which has different sizes of individual parts. Document [3] provides a description of the cage, where there are sections for keeping fish, separated by passages of different sizes. The patent [4] provides for the use of a special cap for the neck of the cage, which changes the design of a typical cage. Document [5] discloses the construction of a cone-shaped cage. The design of the cage is given in [6], the neck of which is closed by tightening a special loop. A description of the fish trap is given in [7], where the diameter and geometric dimensions of the sections where the fish swims are changed. The patent [8] discloses the design of the trawl, which can change its design.

In the present invention, the fish tank (Fig. 1) has a bag (1) made of net fabric and transverse rigid hoops that form the inner space of the bag in the form of separate sections where live fish is placed. Hoops form transitions between separate sections for live fish. At least one hoop (2) is made in the form of a convex closed polygon having equal sides. Each side consists of tubes of different diameters (3) interconnected telescopically. In this case, the end of the tube of the smallest diameter (4) of one side is fixed at the beginning of the tube of the largest diameter (5) of the adjacent side, forming corners. Fastening in the corners between the tubes is hinged (6). The mesh fabric is fixed on each side with the help of threads.

The hoop is made of stainless steel. It is allowed to use plastics, composite materials for the manufacture of the hoop.

The size of the transition between sections is changed taking into account the dimensions and the number of fish caught, which will be placed in the sections. So, for small fish, the tubes are shifted one into the other, and the size of the hoop is reduced, which means that the size of the transition between sections of the cage is reduced. If the fish is large and it is required to increase the size of the transition, then the tubes are moved apart.

The technical result is achieved due to the fact that the hoop of the fish tank is made in the form of a convex closed polygon having equal sides, and each side consists of tubes of different diameters, interconnected by a telescopic method, which can be moved, which provides both a decrease and an increase the geometric dimensions of the fish tank hoop.

The invention is aimed at improving the usability of the fish tank. Industrial implementation is possible on the basis of well-known materials and technologies, as well as components.
