Detailed Description

The present utility model will be further described in detail with reference to the accompanying drawings, for the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, and the described embodiments should not be construed as limiting the present utility model, and all other embodiments obtained by those skilled in the art without making any inventive effort are within the scope of the present utility model.

In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is to be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with one another without conflict.

In the following description, the terms "first", "second", "third" and the like are merely used to distinguish similar objects and do not represent a particular ordering of the objects, it being understood that the "first", "second", "third" may be interchanged with a particular order or sequence, as permitted, to enable embodiments of the utility model described herein to be practiced otherwise than as illustrated or described herein.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein is for the purpose of describing embodiments of the utility model only and is not intended to be limiting of the utility model.

For a better understanding of the embodiments of the present disclosure, the following description of the manner in which oil is detected in the related art will be made with reference to some exemplary embodiments:

in one embodiment, the oil product may be detected by an acoustic pressure method, but the acoustic pressure method has low reliability accuracy and a small detectable range. In one embodiment, the oil product point location detection can be performed by a photoelectric receiving method, but the oil product cannot be detected in a continuous space range in the point location detection process. In one embodiment, the oil product can be detected by a camera monitoring method, but the method needs manual duty and has high detection cost. In one embodiment, the oil leakage detection line can be contacted with the polymer to form a conductive loop by using the swelling extrusion after the polymer contacts oil to detect whether oil leakage exists or not, and the method has the advantages that the detection space can be continuous, and the disadvantage that the reaction rate is very slow and generally needs more than half an hour; and the wire rod is scrapped after the swelling wire is swelled, so that the cost is high and the wire rod can only be used once.

As shown in fig. 1 and 2, the embodiment of the present disclosure provides an oil leakage detection line 1, the oil leakage detection line 1 including a first wire 11; the first wire 11 includes:

an oil-permeable insulating sheath 111;

a first conductive layer 112 disposed inside the insulating sheath 111; the first conductive layer 112 comprises a lipophilic conductive material; the resistance value of the first conductive layer 112 is different in a state where the conductive material is not in contact with oil and in a state where the conductive material is in contact with oil.

In one embodiment, the oil leakage detection line 1 may be provided within a predetermined range of the oil reservoir 2, and the oil leakage detection line 1 is used to detect whether or not oil leakage occurs in the oil reservoir 2. In one embodiment, the oil leakage detection line 1 may be in contact with the oil reservoir 2. Alternatively, the oil leakage detection line 1 may not be in contact with the oil reservoir 2. In one embodiment, the oil reservoir 2 may be an oil tank, or the oil reservoir 2 may also be a pipe for conveying oil. Here, the specific type of the oil reservoir 2 may not be limited. The specific type of oil may not be limiting in embodiments of the present disclosure, and the oil may be gasoline, for example, or the oil may be diesel.

In one embodiment, the first conductive layer 112 includes a predetermined proportion of conductive material therein. Illustratively, the first conductive layer 112 may include 20% to 40% conductive material therein.

In one embodiment, the first conductive layer 112 comprises a lipophilic conductive material, and the first conductive layer 112 further comprises at least one of simethicone, titanium dioxide, silica gel, a cross-linking agent, and white carbon particles.

Illustratively, the first conductive layer 112 may comprise a lipophilic conductive material and an oil-swellable silicone material.

Illustratively, the first conductive layer 112 may be obtained by simultaneously filling a conductive material in a proportion of 20% -40% in silicone rubber, adding a small amount of simethicone to control the structure of the first conductive layer 112 and to play a lubricating role in forming the oil leakage detection line 1, adding white carbon black particles to reinforce the ductility of the first conductive layer 112, adding titanium pigment to increase the corrosion resistance of the first conductive layer 112, and adding a cross-linking agent.

In one embodiment, the insulating sheath 111 is made of a non-conductive material. The insulating sheath 111 may be made of plastic, rubber, silicone, or nylon, for example.

Here, since the insulating sheath 111 is made of a non-conductive material, in a scene where the oil leakage detection line 1 needs to be placed in a conductive loop to determine whether the oil leakage detection line 1 is in contact with oil by detecting a change in the resistance value of the first conductive layer 112, on the one hand, it is possible to reduce a situation where a possible short circuit inside the oil leakage detection line 1 generates spark ignition oil by utilizing the non-conductive property of the insulating sheath 111. In this way, the safety of the oil leakage detection environment can be ensured. On the other hand, the non-conductive property of the insulating sheath 111 can be utilized, so that the detection result of the resistance change of the first conductive layer 112 is not affected by the shunt generated when the conductive object such as a human body touches the oil leakage detection line 1. Thus, the accuracy of oil leakage detection can be ensured.

In one embodiment, the specific shape of the insulating sheath 111 may not be limited, only by ensuring that the first conductive layer 112 is disposed inside the insulating sheath 111. Illustratively, the insulating sheath 111 may be cylindrical, and the first conductive layer 112 may be provided inside the cylindrical insulating sheath 111. Alternatively, the insulating sheath 111 may be plate-shaped, and the first conductive layer 112 may be stacked inside the insulating sheath 111.

In one embodiment, the shape of the first conductive layer 112 is the same as the shape of the insulating sheath 111. Illustratively, the insulating sheath 111 has a hollow cylindrical structure, and the first conductive layer 112 may also have a hollow cylindrical structure.

In one embodiment, the oil-permeable insulating sheath 111 may be made of a predetermined material, and the molecular interval of the predetermined material may be greater than the molecular diameter of the oil. Here, the insulating sheath 111 does not need to be provided with a hole through which oil is supplied. In this way, the first conductive layer 112 can be isolated from the external environment by the insulating sheath 111, so that damage (e.g., acid rain corrosion) of the conductive layer caused by external environmental factors can be reduced. In this way, the service life of the oil leakage detection line 1 can be increased.

In the process that the oil passes through the insulating sheath 111 and contacts the first conductive layer 112, the lipophilic conductive material in the first conductive layer 112 easily adsorbs the oil, so that the oil covers the surface of the conductive material.

In one embodiment, the resistance of the first conductive layer 112 is an initial resistance in a state where the conductive material is not in contact with oil, or the resistance of the first conductive layer 112 is changed to be within a predetermined resistance interval in a state where the conductive material is in contact with oil. The resistance value in the preset resistance value interval is far greater than the initial resistance value. In a state where the conductive material is in contact with the oil, the oil may cover the surface of the conductive material, and at this time, since the oil is not capable of conducting electricity, the conductive performance of the conductive material covered with the oil is lowered, and the resistance of the first conductive layer 112 including the conductive material is increased.

In one embodiment, the amount of oil penetrating any portion of the first conductive layer 112 is greater than a predetermined amount of oil, and the electrical resistance of the first conductive layer 112 is greater than a predetermined electrical resistance. Note that, in the case where the resistance of the first conductive layer 112 is larger than a predetermined resistance, the first conductive layer 112 is in an approximately insulating state.

In one embodiment, a side of the first conductive layer 112 opposite to the insulating sheath 111 is provided with a predetermined number of recesses.

In one embodiment, the inner wall of the recess is inclined at a predetermined angle. In one embodiment, the predetermined angle may be any angle between 90 ° and 180 °.

Here, since a recess is provided in the first conductive layer 112 and the inner wall of the recess is inclined at a predetermined angle, oil may be gathered into the recess along the inclined inner wall when the oil permeates into the first conductive layer 112. At this time, the conductive material located in the predetermined range of the concave portion can be sufficiently contacted with the oil, and its conductive performance is greatly affected by the oil. In this way, it is possible to reduce the case where the change in the conductivity of the conductive material is small due to the excessive dispersion of the oil permeated into the first conductive layer 112, so that the change in the resistance value of the first conductive layer 112 in the state of being in contact with the oil is more remarkable.

In one embodiment, the predetermined number may be determined according to an expanded area of the first conductive layer 112. Illustratively, the expanded area of the first conductive layer 112 may be positively correlated with the predetermined number.

In one embodiment, the recesses are spaced apart a predetermined distance from the first conductive layer 112. In one embodiment, the separation distance may be less than a distance threshold. For example, the distance threshold may be 1cm and the separation distance may be less than 1cm.

In the embodiment of the disclosure, the oil leakage detection line 1 includes a first wire 11; the first wire 11 includes: an oil-permeable insulating sheath 111; a first conductive layer 112 disposed inside the insulating sheath 111; the first conductive layer 112 comprises a lipophilic conductive material; the resistance value of the first conductive layer 112 is different in a state where the conductive material is not in contact with oil and in a state where the conductive material is in contact with oil. Here, since the first wire 11 includes the oil-permeable insulating sheath 111 and the first conductive layer 112 provided inside the insulating sheath 111, the first conductive layer 112 contains a lipophilic conductive material, and the resistance value of the first conductive layer 112 is different in a state where the conductive material is not in contact with oil and in a state where the conductive material is in contact with oil, it is determined whether the oil leakage detection line 1 is in contact with oil and takes a relevant measure by using a change in the resistance value of the first conductive layer 112 when the conductive material is in physical contact with oil while the first conductive layer 112 can be safely protected by the insulating sheath 111. Compared with the mode that the continuity of the detection range, the recycling property of the detection object for detecting the oil product and the detection speed cannot be considered simultaneously in the related art, the embodiment of the disclosure can utilize the resistance change of the conductive material to rapidly detect the oil product in the continuous wiring space corresponding to the oil leakage detection line 1 while the insulating sheath 111 can be utilized to perform safety protection on the first conductive layer 112. And, after the oil product of the first conductive layer 112 volatilizes or is wiped dry, the first conductive layer 112 can be continuously used for detecting the oil product. In this way, in the process of detecting the oil product, the oil product can be detected by recycling the oil leakage detection line 1 comprising the first conductive layer 112, so that the detection cost is reduced; the safety protection of the first conductive layer 112 can be enhanced; the oil product can be rapidly detected in a continuous detection range, so that the requirements of high protection, low cost, high efficiency and a detection mode of the continuous detection range can be met.

In one embodiment, referring to fig. 1 and 2 again, the oil leakage detection line 1 further includes:

a second wire 12 for supporting the first wire 11; the second wire 12 includes:

an insulating layer 121;

the second conductive layer 122, the insulating layer 121 is disposed between the first conductive layer 112 and the second conductive layer 122, the first conductive layer 112 and the second conductive layer are disposed in parallel, and adjacent ends of the first conductive layer 112 and the second conductive layer 122 are connected.

In one embodiment, the oil leakage detection line 1 includes: a first wire 11 and a second wire 12 for supporting the first wire 11; the first wire 11 includes: an insulating sheath 111 capable of oil penetration and a first conductive layer 112 provided inside the insulating sheath 111; the first conductive layer 112 comprises a lipophilic conductive material; the resistance value of the first conductive layer 112 is different in a state where the conductive material is not in contact with oil and in a state where the conductive material is in contact with oil; the second wire 12 includes: the insulating layer 121 and the second conductive layer 122, the insulating layer 121 is disposed between the first conductive layer 112 and the second conductive layer 122, the first conductive layer 112 and the second conductive layer are disposed in parallel, and adjacent ends of the first conductive layer 112 and the second conductive layer 122 are connected.

Here, since the second wire 12 is used to support the first wire 11, and the second wire 12 includes the second conductive layer 122, the second conductive layer 122 is connected to an end adjacent to the first conductive layer 112, and thus, in a case where an end of the second conductive layer 122, which is not connected to the first conductive layer 112, and an end of the first conductive layer 112, which is not connected to the second conductive layer 122, are connected to the same power source, the second conductive layer 122 can be used to form a conductive loop with the first conductive layer 112. At this time, the second conductive line 12 including the second conductive layer 122 can serve as both a support for supporting the conductive silica gel line and a conductive conductor for forming a conductive loop, and in a practical application scenario, it is not necessary to provide a support skeleton for the oil leakage detection line 1 and a conductive conductor for forming a conductive loop with the first conductive line 11, respectively. In this way, the production cost can be reduced, and the volume of the oil leakage detection line 1 can be reduced, so that the oil leakage detection line 1 can be suitable for application scenes with small oil detection space.

In one embodiment, the specific shapes of the first and second wires 11 and 12 may not be limited, and only the second wire 12 needs to be ensured to be in contact with the first wire 11 to support the first wire 11.

Illustratively, the first wire 11 and the second wire 12 may each be cylindrical, in which case the second wire 12 is disposed inside the first wire 11 to support the first wire 11. Alternatively, both the first and second wires 11 and 12 may be plate-shaped, and at this time, the second wire 12 may be stacked under the first wire 11 to support the first wire 11. When the second conductive wire 12 is disposed inside the first conductive wire 11, the insulating sheath 111, the first conductive layer 112, the insulating layer 121, and the second conductive layer 122 may be sequentially disposed from the outermost layer to the center layer of the oil leakage detection line 1. When the second wire 12 is stacked under the first wire 11, the uppermost layer to the lowermost layer of the oil leakage detection line 1 may be the insulating sheath 111, the first conductive layer 112, the insulating layer 121, and the second conductive layer 122 in this order.

In one embodiment, the insulating layer 121 is made of a non-conductive material. Illustratively, the non-conductive material may include at least one of plastic, rubber, silicone, and nylon. In one embodiment, the insulating layer 121 may be made of a material that is non-conductive and impermeable to oil.

In one embodiment, the second conductive layer 122 is made of a metallic material. For example, the second conductive layer 122 may be a copper wire made of copper. Illustratively, the metallic material may include at least one of tungsten, zinc, nickel, iron, platinum, tin, lead, copper, and silver.

In one embodiment, the insulating layer 121 is a coating layer disposed on the second conductive layer 122.

In one embodiment, the insulating sheath 111 is a coating layer disposed on a side of the first conductive layer 112 facing away from the second conductive layer 122.

In one embodiment, the oil leakage detection line 1 includes: a first wire 11 and a second wire 12 for supporting the first wire 11; the first wire 11 includes: an oil-permeable insulating sheath 111 and a first conductive layer 112 provided inside the insulating sheath 111. The first conductive layer 112 comprises a lipophilic conductive material; the resistance value of the first conductive layer 112 is different in a state where the conductive material is not in contact with oil and in a state where the conductive material is in contact with oil; the second wire 12 includes: the insulating layer 121 and the second conductive layer 122, the insulating layer 121 is disposed between the first conductive layer 112 and the second conductive layer 122, the first conductive layer 112 and the second conductive layer are disposed in parallel, and adjacent ends of the first conductive layer 112 and the second conductive layer 122 are connected. The insulating sheath 111 is a coating layer arranged on the side of the first conductive layer 112 facing away from the second conductive layer 122.

Here, since the insulating sheath 111 is permeable to oil, the insulating sheath 111 is a coating layer provided on the first conductive layer 112, and thus the thickness of the insulating sheath 111 is small, and in the case where oil is in contact with the insulating sheath 111, the oil can rapidly permeate through the insulating sheath 111 and penetrate into the first conductive layer 112. Since the resistance value of the first conductive layer 112 is different between the state where the conductive material is not in contact with oil and the state where the conductive material is in contact with oil, and the oil can quickly penetrate through the insulating sheath 111 and penetrate into the first conductive layer 112 when the oil leakage detection line 1 encounters oil, the speed of resistance change of the first conductive layer 112 when the oil encounters oil is high.

In one embodiment, the thickness of the insulating sheath 111 is less than a predetermined thickness. For example, the predetermined thickness may be 3mm, and the thickness of the insulating sheath 111 may be 2mm.

In one embodiment, the insulating sheath 111 comprises an oil-swellable silicone material.

Here, since the insulating sheath 111 includes the silicone material that swells when it encounters oil for the first time, the swelling and extrusion of the silicone material can enable the oil that contacts the silicone material to contact the first conductive layer 112 quickly, thereby triggering the resistance change of the first conductive layer 112. At this time, the speed of the change in the resistance value of the first conductive layer 112 may be increased, and in a scenario where it is necessary to determine whether the oil leakage detection line 1 is in contact with oil using the change in the resistance value of the first conductive layer 112, the detection speed may be increased.

In one embodiment, the conductive material comprises carbon black particles. Here, the conductive material may also be conductive particles.

In one embodiment, the first supply terminal is configured to provide a positive voltage and the second supply terminal is configured to provide a negative voltage. In some application scenarios, the first power supply terminal may be understood as a power supply (VCC, volt Current Condenser) terminal, and the second power supply terminal may be understood as a Ground (GND) terminal.

In one embodiment, the electrical parameter may be a current passing in the conductive loop and the detection module 4 may be configured to determine that the first conductive layer 112 is in contact with oil if the current is less than a current threshold. The current threshold may be determined from a value of current in the conductive loop when the first conductive layer 112 is not in contact with oil. In one embodiment, the detection module 4 may include an ammeter disposed between the first power supply terminal and the first terminal; alternatively, the ammeter is arranged between the second power supply end and the second end; the ammeter is used for detecting the current passing through the conductive loop.
