Abstract

The invention relates to hydrobiology, in particular, to devices for the maintenance and investigation of aquatic organisms. The purpose of the invention is the possibility of training fish in an artificially created stream of water. The aquarium contains two tanks 1 rigidly interconnected by a pipe 2. On the central part of the pipe 2, a rocker arm 4 is installed, which is mounted on a drive shaft consisting of a direct current electric motor 6 and a gearbox 7. The drive is attached to the plate 8 so that the drive axis is at an angle to the vertical, whereby when the electric motor 6 is turned on, the tanks 1, rotating around the axis of the drive, alternately appear at different heights, which leads to the overflow of water from the upper tank to the lower one. 1 il.

The invention relates to hydrobiology, in particular, to devices for keeping and studying aquatic organisms, mainly fish.

The purpose of the invention is the ability to train fish by creating a flow of water by flowing it from one upstream reservoir to another through a pipe connecting them.

The drawing shows the proposed aquarium.

The aquarium contains two spherical reservoirs 1 made, for example, from glass. The tanks 1 are rigidly interconnected in the lower part of the pipe 2 according to the principle of communicating their vessels. In the central part of the pipe 2, between its projections 3, a beam 4 is installed, supporting the pipe with rubber gaskets. The pipe 2 is fixed on the yoke 4 by means of a clamp. The yoke 4 is mounted on the drive shaft 5, consisting of a DC electric motor 6 and a gearbox 7. The drive is attached to the plate 8, its axis is inclined to the vertical. By rotating the plate 8 around the axis 9 located on the rack 10 and changing the position of the fixing clamp 11 in the holes 12 of the rack 13, the angle of inclination changes arbitrarily. Racks 10 and 13 are rigidly fixed on the base 14.

Aquarium works as follows.

In the initial position, when one of the reservoirs 1 is in the lower position, the angle of inclination of the aquarium is determined depending on the task. By rotating the plate 18 around the axis 19, this position is fixed by the clamp 11 in one of the holes 12 of the rack 13. The tank 1, which is in the lower position, is filled with water and the aquatic organisms or fish being trained are placed into it. Depending on the task, select

The rotational speed of the tanks is ensured, which is provided by the DC motor 6 through the gearbox 7. This imposes a predetermined speed of water in the pipe 2 and the tanks 1.

The direct current electric motor 6 is turned on, which by means of gear 7 is connected to rotational movement of shaft 5. The beam 4 is rigidly connected on one side to shaft 5 of gear 7 and on the other side to pipe 2, begins to rotate the latter and the tanks that are one rigid the system. When this rigid system is rotated through 180 °, the relative position of the tanks 1 changes. At the same time, water with aquatic organisms, due to the location of both reservoirs 1 at different levels relative to one another, flows through pipe 2 from the reservoir in the upper position to the reservoir in the lower position.

After finishing a session of training or examining fish or other animals, the electric motor 6 is disconnected, the clamp is loosened, manually turning the reservoirs 1 5 around the longitudinal axis of the pipe 2, and water is poured from the aquarium.
