The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
This embodiment describes a leakage detection device, which uses the leakage of low conductivity or insulating liquid to dissolve soluble salt to detect the leakage of low conductivity or insulating liquid.
As shown in fig. 1 and 2, the detection device comprises a water absorption isolation layer 1, a waterproof isolation layer 2, a soluble salt layer 4, a detection conductor 5, a connecting circuit 6, a power supply module 7 and a signal output module 8.
The water absorption isolation layer 1 and the waterproof isolation layer 2 are respectively of an annular cylindrical structure, and the water absorption isolation layer 1 is wrapped outside the soluble salt layer 4 through the waterproof isolation layer 2.
The water absorption isolation layer 1 is made of water absorption materials and used for absorbing water vapor in air to prevent the water vapor from entering the detection device, and meanwhile, leakage liquid is not influenced to enter the detection device.
The waterproof isolating layer 2 is arranged between the water-absorbing isolating layer 1 and the soluble salt layer 4, and the waterproof isolating layer 2 has a certain thickness and is made of a waterproof material. When the water absorption isolation layer 1 is wet due to water vapor absorption, the water absorption isolation layer 1 can be prevented from being in direct contact with the soluble salt layer 4 through the waterproof isolation layer 2. Through holes 3 are uniformly distributed on the waterproof isolation layer 2 and are arranged at intervals, and the diameters of the through holes 3 are smaller than the diameters of salt particles in the soluble salt layer 4, so that the waterproof isolation layer 2 can prevent salts from scattering when the soluble salt layer 4 is stabilized. And the through holes 3 can prevent water vapor in the air from entering the soluble salt layer 4 at the same time of preventing the water-proof isolation layer 2 from entering the soluble salt layer 4, and can ensure that the leakage liquid passing through the water-absorbing isolation layer 1 enters the soluble salt layer 4.
A soluble salt layer 4 is disposed within the water resistant barrier layer 2, the soluble salt layer 4 being comprised of salts that are soluble in the low conductivity or insulating liquid being tested. When the leaked liquid passes through the water absorption isolation layer 1 and the waterproof isolation layer 2 and enters the soluble salt layer 4, the salt of the soluble salt layer 4 is dissolved in the leaked liquid, and the conductivity of the leaked liquid is improved.
The detection conductor 5, the connecting circuit 6, the power module 7 and the signal output module 8 form a detection circuit. The detection conductor 5 consists of two conductors which are placed in parallel and are not communicated under normal state, and the detection conductor 5 is placed in the soluble salt layer 4. When the leakage enters the soluble salt layer 4 and dissolves a certain amount of salt, the leakage is communicated with the two conductors of the detection conductor 5. One side joints of two conductors of the detection conductor 5 are respectively connected with the connecting circuit 6, and the power supply module 7 and the signal output module 8 are connected in series into the connecting circuit 6 through connecting wires and form a series-connection detection circuit with the detection conductor 5. After the two conductors of the detection conductor 5 are communicated, the power supply module 7 supplies power to the whole detection circuit, and the signal output module 8 outputs a signal to the outside after being electrified, so that the liquid leakage condition is shown.
In the embodiment, the detection conductor 5 is directly arranged in the soluble salt of the soluble salt layer 4, so that the detection circuit can be quickly communicated when liquid leakage occurs, an alarm is given, and the damage of the liquid leakage to the electronic equipment is avoided.
In the present embodiment, the detection conductor 5 may be two conductors having any shape and not in contact with each other. The signal output module 8 can be an LED lamp, a display screen, a loudspeaker and other alarm devices.
When the detection device of the embodiment is used for detecting leakage, the part where the water absorption isolation layer 1 is located is placed at a leakage flowing or dropping position.
When the weeping gets into waterproof isolation layer 2 through isolation layer 1 that absorbs water to enter into soluble salt layer 4 by thru hole 3, the weeping dissolves the partly soluble salt in the soluble salt layer 4, the conductivity improves, switch-on two unconnected conductors of detection conductor 5 in the soluble salt layer 4, detection conductor 5, power module 7, signal output module 8 are communicated through connecting circuit 6, power module 7 is the power supply of signal output module 8, signal output module 8 sends detection signal after the circular telegram, carry out the weeping warning.
When the two conductors of the detection conductor 5 are not in contact with each other, the detection circuit keeps an off state, and the signal output module 8 does not act, which indicates that no liquid leakage occurs.
Simultaneously, when the air is moist, the isolation layer 1 that absorbs water absorbs the steam in the air, prevents that steam from passing through thru hole 3 and getting into soluble salt layer 4, and because of absorbing the moist isolation layer 1 that absorbs water of steam avoid with soluble salt layer 4 direct contact through waterproof isolation layer 2, further prevent steam and get into soluble salt layer 4, reducible detection device appears the condition of false alarm because of weing.
While the principles of the invention have been described in detail in connection with the preferred embodiments thereof, it will be understood by those skilled in the art that the above-described embodiments are merely illustrative of exemplary implementations of the invention and are not limiting of the scope of the invention. The details in the embodiments do not constitute the limitations of the scope of the present invention, and any obvious changes such as equivalent transformation, simple replacement, etc. based on the technical solution of the present invention all fall within the protection scope of the present invention without departing from the spirit and scope of the present invention.
