FIELD: diving outfit. ^ SUBSTANCE: proposed tug-boat has hull with power supply unit mounted inside it; output of power source is connected to first input of power supply switchboard. Outputs of switches of engine and propulsion complex and lighting fixture are connected respectively to third and fourth inputs of power supply switchboard; negative output of power supply source is connected to second input of power supply switchboard and to first and second outputs of power supply switchboard through lighting fixture and engine and propulsion complex. Besides that, tug-boat is provided with matching device, adjustable reference voltage source, memory element, comparators, adders and integrator. Positive output of power supply source is connected to first outputs of matching device, adjustable reference voltage source and memory element whose second outputs are connected with center tap of power supply source; negative output of power supply source is connected to third inputs. First output of matching device is connected with first inputs of first comparator and with second inputs of first and second adders. Second inputs of first and second comparators are connected with respective outputs of adjustable reference voltage source. Output of first adder is connected with first input of third comparator and output of second adder is connected with first input of fourth comparator. Comparator outputs are connected with inputs of third adder whose output is connected via integrator with second input of memory element; memory element output is connected with inputs of switch of engine and propulsion complex and lighting fixture. ^ EFFECT: possibility of obtaining complete service life of power supply source. ^ 1 dwg |
