Description

The utility model relates to the field of industrial and recreational fishing and solves the following problem of concentration of a certain variety of aquatic organisms using selective acoustic waves for their further catch in a given area of the reservoir.

A similar analogue is known which is close to the device by the sign of action: acoustic impact (low frequency propagation in water) on aquatic organisms. The official name of the analog is Fishmagnet-2 (patent No. 78405). The useful model Fishmagnet-2 belongs to the field of amateur and sport fishing and serves to concentrate fish in the zone of action of gear and fishing gear. The electronic bait for fish contains a sealed enclosure with elements of an electrical circuit and fasteners, a device for supplying sound and light signals, as well as a vibration attracting signal, a device for creating an electric attracting pulse signal to attract fish and a power source.

The disadvantages of the analogue object are: high cost, low work efficiency, non-selectivity of action, lack of a system for moving through a reservoir.

The closest adopted for the prototype of the utility model is the electronic acoustic bait "Simulator of fish sounds" (patent No. 2182765), intended for use in industrial fishing as a device for the concentration of fish in the range of fishing gear, including in a cloudy or completely opaque water, and containing a sealed cylindrical housing (box) with a power supply and an electronic circuit connected electrically via a cable with a sonar transducer in the form of a piezoceramic head Application of spherical shape with positive buoyancy.

However, this object cannot be used, since its disadvantage is its low efficiency when used in conditions of noise interference, for example, caused by the flow of water, waves, etc., which muffle the artificial sound signal generated by the acoustic bait, as well as the inconvenience of operation due to the cable connection of the sonar transducer with the housing of the device.

The essence of the utility model is as follows: using a sound signal of selective action, fish of a certain variety and age composition are attracted. This is based on the fact that fish up to six months of age are deaf or do not distinguish signals, so the device would not attract small fish, which is unprofitable for fishing and would violate Russian legislation in the field of fish protection. Since fry and fish that have not reached the age and weight that are profitable for fishing will not lure, this ensures the preservation of the species composition of fish, which will further increase the efficiency of the fishing process. The disadvantages of the prototype are eliminated due to the fact that the device does not have external wires, it is able to move as a result of remote control, which will simplify its operation and, ultimately, increase the efficiency of the fishing process.

It is proposed to use an audio frequency generator as a basis, which generates electrical signals corresponding to either the range of sound perception by hydrobionts of a certain variety and age, or a bio signal that controls the behavior of hydrobionts. The generator is connected to a sound frequency emitter made on the basis of a metal membrane. Due to the tight box, the generator is protected from water penetration.

The proposed device allows you to fish for pre-defined fish species, thereby preserving the species composition of other species that are not commercial in this case. The main differences of our device from other analogues:

1) the ability to choose the type of fish for fishing, i.e. selectivity;

2) accounting for noise of natural and artificial origin;

3) the ability to move through a reservoir as a result of remote control.

To ensure the buoyancy of the electronic part of the concentrator on water, a “float” is used. The hub uses an autonomous power source located inside a sealed enclosure.

The proposed device operates as follows: (Fig. 1) the concentrator is installed on the surface of the reservoir using a “float” (3) and under the action of the control unit (1), an electric motor with a screw (5) and a steering mechanism consisting of a vertical metal plate (8 ) connected to an electric motor (4) moves to a predetermined area of the reservoir. When the control unit (1) is turned on, the sound frequency generator (2) and electric motors (4), (5) are started to move the concentrator along the surface of the reservoir. The generator signal is supplied to the emitter (7), mounted on a removable rod (6), consisting of a metal membrane oscillating under the influence of a magnetic field, which converts the electrical signal into an acoustic signal to attract hydrobionts.

Thus, the proposed device allows high-performance selective fishing of aquatic organisms and is convenient in operation. During fishing, the device concentrates the specified types of hydrobionts in certain areas of the water area, as a result of which the “Law on Fish Protection” and the license for fishing are not violated.
