APPARATUS FOR REGULATING TEMPERATURE IN BEEHIVE Russian patent published in 1999 - IPC

FIELD: apiculture, in particular, equipment used in individual and collective apiaries. SUBSTANCE: apparatus has outer temperature sensor, outer temperature setter, three comparison circuits, beehive internal temperature sensor, controllable temperature setter, photo-detector, light emitter, pulse amplifier-former, initial mounting unit, two AND gates, trigger, temperature setter control unit, microphone, microphone amplifier, two band filters, power commutation element, heater and power source connection terminals. Such construction allows heating temperature required for given period of development of bee family to be optimized and necessity for presence of bee keeper at apiary to be eliminated, since bees themselves "set" required heating temperature depending on bee family development extent. EFFECT: increased efficiency and provision for precise setting of temperature in beehive. 1 dwg
