Description
Technical Field
The utility model belongs to marine life saving equipment field, concretely relates to marine life saving equipment emergency power supply device.
Background
When marine aviation accidents happen suddenly, a plurality of emergency lifesaving devices are started and used for emergency rescue, distress signal sending, lifesaving positioning and the like. However, the superior performance of the highly integrated electronic information system and device is extremely dependent on the onboard power supply, when an accident occurs to the aircraft, especially to a fighter plane, the onboard power supply is likely to be in a paralyzed state, or the power supply cable is damaged and cannot supply power normally, so that the emergency life-saving device cannot be started, and the irretrievable loss is caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a marine life saving equipment emergency power supply device, only charge to energy storage electric capacity when on-machine power supply system is normal, just no longer consume the energy afterwards, so can hardly increase the burden for on-machine power supply system. The capacity of the electrically activated chemical battery can be flexibly selected according to the power consumption and the working time of the emergency life-saving device, and the requirements of different power equipment can be flexibly met.
In order to solve the technical problem, the utility model adopts the technical scheme that: an emergency power supply device of a marine life-saving device comprises an energy storage capacitor, an emergency power supply and a water inlet detection circuit, wherein the energy storage capacitor, the emergency power supply and the water inlet detection circuit are respectively connected with a switch; the emergency power supply and the onboard power supply system are connected with the emergency life-saving device; when the water inlet signal is not detected by the water inlet detection circuit, the switch is switched off; when the water inlet detection circuit detects a water inlet signal, the switch is switched on, and the energy storage capacitor supplies energy to the emergency power supply to activate the emergency power supply.
The emergency power supply is an electrically activated chemical battery BAT.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses only charge to energy storage capacitor when power supply system is normal on the machine, just no longer consume the energy afterwards, so can not increase the burden for power supply system on the machine almost. The capacity of the electrically activated chemical battery can be flexibly selected according to the power consumption and the working time of the emergency life-saving device, and the requirements of different power equipment can be flexibly met.

Fig. 1 is a schematic view of a connection structure according to an embodiment of the present invention.
Detailed Description
To facilitate understanding and application of the present invention by those of ordinary skill in the art, the present invention will be described in further detail with reference to the accompanying drawings and examples, it being understood that the examples described herein are only for the purpose of illustration and explanation and are not intended to limit the present invention.
The technical scheme of the utility model is that: an emergency power supply device of a marine life-saving device comprises an energy storage capacitor, an emergency power supply and a water inlet detection circuit, wherein the energy storage capacitor, the emergency power supply and the water inlet detection circuit are respectively connected with a switch; the emergency power supply and the onboard power supply system are connected with the emergency life-saving device; when the water inlet signal is not detected by the water inlet detection circuit, the switch is switched off; when the water inlet signal is detected by the water inlet detection circuit, the switch is switched on, and the energy storage capacitor supplies energy to the emergency power supply to activate the emergency power supply.
The emergency power supply is an electrically activated chemical battery BAT.
The water inlet detection circuit judges whether the airplane has a fault and falls into water by using the conductivity of the water, and controls the switch to be switched on when a water inlet signal is detected; the switch is used for controlling whether the energy storage capacitor outputs energy to the electrically activated chemical battery or not; the energy storage capacitor stores energy when an onboard power supply system is normal, and when an accident occurs, the energy of the energy storage capacitor is used for exciting the electricity generation activated chemical battery; the electric activation type chemical battery is activated by energy of the energy storage capacitor, and provides an emergency power supply for the emergency life-saving device.
When the airplane normally flies, the power supply system M0 on the airplane supplies power to the emergency lifesaving device M1, and the energy storage capacitor C is fully charged. At the moment, the water inlet signal is not detected by the water inlet detection circuit U, the switch K is in an off state, the energy of the energy storage capacitor C is not released, the whole emergency power supply basically does not consume energy, and the load of an airplane power supply system is not increased.
When the aircraft accidentally falls on the water surface, the water inlet detection circuit U detects a water inlet signal by using the conductivity of water, so that the control switch K is switched on, the energy of the energy storage capacitor C is released to an activator of the electric activation type chemical battery BAT, and the electric activation type chemical battery BAT is activated. At this time, the electrically activated chemical battery BAT can independently supply power to the emergency life saving device M1 regardless of whether the onboard power supply system M0 is normal or not.
In the scheme, the emergency power supply only charges the energy storage capacitor when the onboard power supply system is normal, and then no energy is consumed, so that the burden of the onboard power supply system is hardly increased. The capacity of the electrically activated chemical battery can be flexibly selected according to the power consumption and the working time of the emergency life-saving device, and the requirements of different power equipment can be flexibly met.
It is right only to go up the preferred example of the utility model discloses, and not right the utility model discloses a scope is injectd, the event is not deviating from the utility model relates to an under the prerequisite of spirit, ordinary engineering technical personnel in the field is right the equivalent change or the decoration that structure, characteristic and principle do, all should fall into the utility model discloses in the protection range of the application for a patent.
