Description
Technical field
The invention belongs to avionic device technical fields, and in particular to a kind of water induction sensor.
Background technique
Water induction sensor is installed aboard, when aircraft at sea has an accident, water induction sensor by after seawater immersion,
Its resistance value in the seawater declines to a great extent relative to the resistance value in air, may determine that water induction according to the variation of its resistance
Whether sensor intakes, and it is marine to judge whether aircraft sinks to this.
When aircraft gradually starts installation for marine accident both at home and abroad at present the throwing of flight data recording put logger or
Floating on water surface logger.Such flight data recorder requires to automatically disengage with aircraft after aircraft enters water, and water induction passes
Sensor after determining that aircraft enters water, can put separating mechanism to the throwing of flight data recorder for determining whether aircraft enters water
It provides to throw and puts separation signal.
Summary of the invention
Goal of the invention:
The object of the present invention is to provide a kind of water induction sensors to determine whether aircraft sinks when for the accident of aircraft sea
Enter marine, and provides throwing for the flight data recorder on aircraft and put separation signal.
Technical solution:
A kind of water induction sensor, which is characterized in that including outer core, inner core, partition, positive plate, negative plate, wherein outer
Core and inner core are tubular conductive structure, and outer core inner is equipped with protrusion connecting column, and inner core reversely buckles into the connecting column of outer core, and leads to
Partition is crossed to be dielectrically separated from the holding of outer core;Outer core contacts conducting with negative plate, and inner core contacts conducting with positive plate, positive/negative plate it
Between be isolated by barrier insulation, and positive/negative plate has part outstanding outside outside core, is provided with inlet opening on outer core.
The sensor further includes outer cover, and outer cover is tubular structure, and the outside for being placed in outer core is fixed by outer cover screw,
It which is provided with outer cover inlet opening.
Several inlet openings are also equipped on the inner core.
Positive plate and negative plate are the cyclic structure with long handle, and long handle stretches out outside outer core, and annular plate can be inserted in outer core
The annular plate of connecting column, positive plate is contacted by plate face with inner core, and the annular plate of negative plate is connect by annular distance inner face with outer core
Column contact.

Specific embodiment
One of specific embodiments of the present invention are see Figure of description, including outer core, inner core, partition, positive plate, cathode
Plate, wherein outer core and inner core are tubular conductive structure, and outer core inner is equipped with protrusion connecting column, and inner core reversely buckles into outer core
Connecting column, and be dielectrically separated from by partition and the holding of outer core;Outer core contacts conducting with negative plate, and inner core is contacted with positive plate and led
It is logical, it is isolated between positive/negative plate by barrier insulation, and positive/negative plate has part outstanding outside outside core, is provided on outer core
Inlet opening, wherein outer core 2 is connect by mounting hole 12 with external equipment.Lower clapboard 3, inner core 4, positive plate 5, negative plate 6 and on
Partition 10 passes through the connecting column 13 of outer core 2, is fixed on outer core 2 by self-locking nut 9.Inner core 4 and outer core 2 pass through lower clapboard 3
Separate and contacted with positive plate 5, positive plate 5 is isolated with negative plate 6 by upper spacer 10, and negative plate 6 is contacted with outer core 2.Blanking cover 7
It is connect with blanking cover screw 8 with the blanking cover threaded hole 14 of outer core 2.Outer cover 1 passes through the outer cover threaded hole 16 of outer cover screw 11 and outer core 2
Connection.The outer cover inlet opening 19 of outer cover 1, the lateral inflow hole 15 of outer core 2, inner core 4 inner core inlet opening 19 between arranged in dislocation,
To prevent metallic foreign body from entering inside water induction device.
When water induction sensor is not immersed in the water, mutually isolated between outer core 2 and inner core 4, resistance value is very big, works as water
After inductive pick-up is immersed in the water, outer core 2 is full of water with inner core 4.Water keeps resistance value between outer core 2 and inner core 4 rapid as conductor
So decline, the negative plate 6 contact with outer core 2 and the positive plate 5 contacted with inner core 4 are the output of this resistance variations, as entering water
Signal is sent to external equipment.It is an advantage of the invention that its is compact-sized, enter that water trigger theory is simple, and signal output is reliable.
