HYDROPONIC INSTALLATION Russian patent published in 2019 - IPC A01G31/02 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, in particular to hydroponic cultivation of plants. Installation contains control unit (1), cultural solution level sensor (2), ozonizer (3) with an air duct and a heat supply installation communicated with cultivation vessel (4), pump (5), discharge (6) and supply (7) pipes. Installation also has tanks for preparing nutrient solution (8) and for monitoring its condition (9), tank (10) for reserve nutrient solution and electroactivator (14). Heat supply installation of the nutrient solution is made in the form of a pair of Peltier elements for heating (11) and cooling (12), which are equipped with radiators (13). Peltier elements (11 and 12) are installed under tank (8), which has valves (17) for communication with electroactivator (14) and cultivation vessel (4) and pump (5) for communication with electroactivator (14) and tank (9). Vessel (4) is set at an angle of 4–9° to the horizon in a vertical plane. Tank (9) has additional pump (16) connected to cultivation vessel (4), temperature sensor (18), pH sensor (19), nutrient solution level sensor (2), pipeline (7). Pipeline (7) is connected to ozonizer (3) and to tank (10), equipped with emergency pump (15). Control unit (1) is electrically connected to Peltier elements (11) and (12), valve (17) supplying the nutrient solution to tank (8) from cultivation vessel (4), valve (17) supplying the nutrient solution to electroactivator (14), level sensors of nutrient solution (2), temperature (18) and pH (19), pumps and ozonizer (3).

EFFECT: increase in the efficiency of growing plants by the hydroponic method.
