APPARATUS FOR CONTROLLING GAS HEATING AT FLOOR BREEDING OF POULTRY AND AGRICULTURAL ANIMALS Russian patent published in 2003 - IPC

FIELD: agriculture, possibly monitoring of common and local heating at floor breeding of poultry and agricultural animals by means of heaters having radiant and convection heat sources. SUBSTANCE: apparatus includes biocalorimeter connected through unit for controlling on-floor convective air flow in agricultural room with unit for controlling IR-heating of irradiator. Biocalorimeter is in the form of heat bridge being shaped cylinder of highly heat-conducting material. Pickup for measuring heat flux is arranged on upper end portion of heat bridge. In lower portion biocalorimeter has two telescopic tubes joined with heat bridge. Outer tube is rigidly cemented into floor of agricultural room. First thermocouple of heat bridge of temperature controlling unit is connected with first inlet of comparator. Second inlet of first comparator is connected through first actuating mechanism with rheochord of high-power heater placed under first thermocouple in heat bridge. Over first thermocouple second low-power heater is placed and over it under heat flux pickup second thermocouple is arranged. Second thermocouple is differentially connected with first thermocouple. Outlet of differential thermocouple is connected with first inlet of second comparator. Second inlet of second comparator is connected with second setter. Outlet of second comparator is connected through second actuating mechanism with rheochord of low power heater. Heat flux pickup is connected with first inlet of third comparator in unit for controlling convective heat flux. Second inlet of third comparator is connected with third setter; outlet of third comparator through registering device is connected with first inlet of fourth comparator. Second inlet of fourth comparator is connected with third setter. Outlet of third comparator is connected through third actuating mechanism of unit for controlling IR-heating of irradiator with second motor of actuating mechanism for vertically moving IR-burner. EFFECT: optimized enhanced-accuracy control of heating mode in zone of floor breeding of poultry and agricultural animals in agricultural room due to direct measuring and controlling heat flux at level of backs of animals or poultry. 1 dwg
