Description

Technical Field

[0001] The invention relates to the field of liquid leakage detection, and in particular to a liquid leakage detection line. Background Art

[0002] In today's era of rapid industrial development, liquids play a vital role in the storage, transportation and processing of various fields. Whether it is the transportation of various hazardous chemicals in the chemical industry, the storage and transportation of crude oil and refined oil in the petroleum industry, or the canning and transportation of products in the food and beverage industry, the integrity of liquid containers and pipeline systems is directly related to the smooth progress of production, the guarantee of product quality, and the safety of the environment and personnel.

[0003] Traditional leakage detection devices have many limitations, such as low detection accuracy, slow response speed, and limited scope of application. For example, some methods based on manual inspection, although simple and direct, are limited by manpower, time, and the experience level of the inspectors, and it is difficult to achieve real-time and comprehensive monitoring of large-scale equipment. Inspectors may not be able to detect leakage in hidden parts in time, or may not be able to detect it until a long time after the leakage occurs. During this period, the leakage may have caused serious consequences, such as environmental pollution caused by the leakage of chemical raw materials, fire and explosion hazards, and product contamination in the food industry leading to food safety problems. In addition, some detection equipment based on a single physical principle, such as devices that rely solely on pressure monitoring, has greatly reduced detection accuracy when facing complex pipeline systems and liquids of different media. Because pressure changes may be interfered by many factors, such as normal fluctuations of fluids in pipelines, the impact of temperature changes on pressure, etc., it is easy to make misjudgments. Moreover, these traditional detection methods can often only detect specific types of containers or pipelines, and have poor versatility. Once the material, shape, or working environment of the equipment changes, it may be necessary to readjust or replace the detection equipment, which undoubtedly increases the detection cost and time cost of the enterprise.

[0032] Reference Figure 1 To Attachment Figure 3 As shown, a liquid leakage detection line according to an embodiment of the present invention is schematically shown.

[0033] Figure 1 : is a schematic diagram of the overall structure of the liquid leakage detection line 1 according to the first preferred embodiment of the present invention. In this embodiment, the liquid leakage detection line 1 includes a support component 10, at least one conductive component 20 and a braided component 30. In this embodiment, the conductive component 20 includes a first conductive unit 21 and a second conductive unit 22. The first conductive unit 21 and the second conductive unit 22 are arranged outside the support component 10, and the braided component 30 is covered on the outside of the first conductive unit 21 and the second conductive unit 22. In other words, the first conductive unit 21 and the second conductive unit 22 are wrapped by the braided component 30, and the first conductive unit 21 and the second conductive unit 22 are spaced apart from each other by the braided component 30 and the support component 10.

[0034] Preferably, in this embodiment, the first conductive unit 21 and the second conductive unit 22 are twisted on the outside of the supporting component 10, that is, the outside of the first conductive unit 21 and the second conductive unit 22 are covered with the woven component 30 and twisted on the surface of the supporting component 10, which is beneficial to increase the contact area between the woven component 30 and a liquid to achieve all-round detection.

[0035] The first conductive unit 21 and the second conductive unit 22 are suitable for being electrically connected through the liquid, so as to detect the presence of the liquid according to the change of the conductive state between the first conductive unit 21 and the second conductive unit 22. The liquid can be water or a liquid containing water and a water-soluble organic solvent, such as water; an acidic solution such as hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid, acetic acid; an alkaline aqueous solution such as ammonia water and sodium hydroxide; an organic solvent such as methanol, ethanol, propanol, etc. That is to say, it is defined that there is a conductive state and a non-conductive state between the first conductive unit 21 and the second conductive unit 22. When the environment where the leakage detection line 1 is located has a leakage, the braided component 30 contacts the liquid and absorbs the liquid, so that the first conductive unit 21 and the second conductive unit 22 are electrically connected through the liquid to achieve the conductive state; when the environment where the leakage detection line 1 is located has no leakage, there is no liquid between the first conductive unit 21 and the second conductive unit 22, so the first conductive unit 21 and the second conductive unit 22 are in a non-conductive state.

[0036] Specifically, the braided assembly 30 includes a first braided unit 31 and a second braided unit 32, wherein the first braided unit 31 is covered on the outside of the first conductive unit 21, and the second braided unit 32 is covered on the outside of the second conductive unit 22. The first conductive unit 21 and the second conductive unit 22 are respectively wrapped by the first braided unit 31 and the second braided unit 32, and the first conductive unit 21 and the second conductive unit 22 are spaced apart from each other by the first braided unit 31, the second braided unit 32 and the supporting assembly 10.

[0037] The support assembly 10 includes two support frames 11 , two built-in cores 12 and at least two installation areas 13 . The built-in cores 12 are arranged in the support frames 11 , which can further improve the support strength of the support frames 11 and ensure the durability of the liquid leakage detection line 1 .

[0038] It is worth mentioning that, in this embodiment, the two support frames 11 are twisted together to form the installation area 13 on the surface, and the first conductive unit 21 and the second conductive unit 22 are twisted in the installation area 13 and separated by the support frames 11 .

[0039] In this embodiment, the material of the support frame 11 is one of XLPE, PVDF, FEP, ETFE, PFA, PP, PE or low smoke halogen-free, which has good corrosion resistance, chemical stability and mechanical properties, so that the leakage detection line 1 can adapt to different working environments. The material of the built-in core 12 is one of aramid fiber, carbon fiber fiber, steel wire, copper clad steel, and ultra-high molecular weight polyethylene fiber.

[0040] In the present embodiment, preferably, the first conductive unit 21 and the second conductive unit 22 are both formed by twisting 19 tinned copper wires with a diameter of 0.10 mm. When leakage triggers electrical signal conduction, multiple tinned copper thin wires can enhance the bending resistance of the first conductive unit 21 and the second conductive unit 22, thereby more stably transmitting the leakage detection signal, ensuring the timeliness and accuracy of the leakage detection line 1. It should be understood by those skilled in the art that in other possible implementations, the material of the first conductive unit 21 and the second conductive unit 22 can also be implemented as one of tinned copper, tinned copper alloy, nickel-plated copper or nickel-plated copper alloy. Therefore, the material, quantity and diameter of the first conductive unit 21 and the second conductive unit 22 can be changed according to actual needs, which is not a limitation of the present invention.

[0041] In this embodiment, the material of the first weaving unit 31 and the second weaving unit 32 is a wear-resistant and water-permeable material such as basalt silk, PPS silk, aramid silk, carbon fiber silk, ultra-high molecular weight polyethylene fiber, PET silk, polyester yarn or nylon silk. For example, a plurality of wear-resistant and water-permeable materials such as basalt silk, PPS silk, aramid silk, carbon fiber silk, ultra-high molecular weight polyethylene fiber, PET silk, polyester yarn or nylon silk are woven by a weaving machine to form the first weaving unit 31 and the second weaving unit 32. When leakage occurs, its fiber structure can quickly allow liquid to penetrate, thereby improving the detection accuracy of the leakage detection line 1. Preferably, in the embodiment of the present application, the mesh count of the first weaving unit 31 and the second weaving unit 32 is 11±1 mesh.

[0042] In addition, the material of the first weaving unit 31 and the second weaving unit 32 can also be covered with semiconductors without being woven by the weaving machine. For example, the material of the first weaving unit 31 and the second weaving unit 32 is one of semi-conductive PE, semi-conductive TPE, semi-conductive PVC, semi-conductive TPU or semi-conductive FEP. The materials of the first braided unit 31 and the second braided unit 32 can be selected according to different detection environments to meet the detection requirements. In one embodiment, for example, it is necessary to detect liquid leakage in the environment of the chemical industry. Here, if there is a slight leak in the pipeline or storage tank, the corrosive liquid may seep out quickly, which will not only damage the equipment, but also easily cause serious safety accidents and environmental pollution problems. At this time, the first braided unit 31 and the second braided unit 32 are made of basalt silk. Basalt silk has excellent corrosion resistance due to its special mineral composition and stable chemical structure. Even if it is immersed in concentrated sulfuric acid, concentrated hydrochloric acid or high-concentration sodium hydroxide solution for a long time, it can still maintain the stability of its physical properties, and the fiber structure will not be easily eroded or disintegrated. Moreover, the water absorption of basalt silk itself can keenly capture the clues of liquid leakage. Once the liquid seeps out, it will be quickly absorbed by its fibers, so that the first conductive unit 21 and the second conductive unit 22 are electrically connected through the liquid to achieve the conductive state. In another possible implementation, for example, it is necessary to detect liquid leakage in an electronic chip manufacturing workshop, where the cleanliness and safety requirements of the environment are almost harsh. Any tiny impurities, particles or liquid leakage may cause the chip to short-circuit and be scrapped, resulting in huge economic losses. In view of this, the highly absorbent polyester yarn improved by a special process has a surface covered with fine microporous structures. When extremely small ultrapure water or chemical reagents leak in the chip production equipment, the polyester yarn can quickly absorb the leaked liquid by virtue of its super strong capillary action, thereby making the first conductive unit 21 and the second conductive unit 22 electrically connected through the liquid to achieve the conductive state and efficiently conduct the detection signal. At the same time, the polyester yarn is soft in texture and fine in fiber. It will not generate static electricity during the adsorption of the leaked liquid, effectively avoiding the potential risk of damaging the chip due to electrostatic discharge. In another possible implementation, for example, it is necessary to detect liquid leakage in a high-temperature boiler room. The aramid yarn material has high temperature resistance and can better adapt to the high temperature environment to ensure the detection accuracy of the leakage detection line 1. Based on this, according to different detection environments, there are multiple options for the manufacturing materials of the first weaving unit 31 and the second weaving unit 32, which improves the high adaptability and practicality of the liquid leakage detection line 1.

[0043] In addition, the leakage detection line 1 can be flexibly arranged according to different objects to be detected and fixed in different ways, which is conducive to the flexible installation and arrangement of the leakage detection line 1, meets the detection needs of different places, and improves the applicability of the leakage detection line 1.

[0044] In another possible implementation of this embodiment, the leakage detection line 1 further includes an outer covering component 40, which is covered on the outside of the support component 10 and wraps the support component 10, the conductive component 20 and the braided component 30. The material of the outer covering component 40 is one of basalt silk, PPS silk, aramid silk, ultra-high molecular weight polyethylene fiber, PET silk, polyester yarn or nylon silk.

[0045] The following is an exemplary description of the manufacturing method of the liquid leakage detection line 1: Twisting to form a first conductive unit and a second conductive unit; Disposing a first braided unit and a second braided unit outside the first conductive unit and the second conductive unit in a manner of covering the first conductive unit and the second conductive unit; Extruding a support frame and disposing an internal core inside the support frame; and The first conductive unit and the second conductive unit wrapped with the first braiding unit and the second braiding unit are twisted and wrapped on the supporting frame.

[0046] Preferably, the material of the braided component 30 is one of basalt wire, PPS wire, aramid wire, carbon fiber wire, ultra-high molecular weight polyethylene fiber, PET wire, polyester yarn, nylon wire, semi-conductive PE, semi-conductive TPE, semi-conductive PVC, semi-conductive TPU or semi-conductive FEP, the material of the supporting skeleton 11 is one of PVDF, FEP, ETFE, PFA, PP, PE or low-smoke halogen-free, the material of the built-in core 12 is one of steel wire, aramid, ultra-high molecular weight polyethylene fiber or carbon fiber, and the material of the first conductor unit 21 and the second conductor unit 22 is one of tinned copper, tinned copper alloy, nickel-plated copper or nickel-plated copper alloy.

[0047] After the step of twisting the first conductive unit and the second conductive unit wrapped with the first weaving unit and the second weaving unit in the support frame, the step also includes: weaving an outer covering component on the outside of the support component in a manner of wrapping the support component, the first conductive unit, the second conductive unit, the first weaving unit and the second weaving unit inside.

[0048] As attached Figures 4 to 5 A liquid leakage detection line 1A provided by a second preferred embodiment of the present invention is explained. Figure 3 1 is a cross-sectional view of the liquid leakage detection line 1A according to the second embodiment of the present invention. The liquid leakage detection line 1A in this embodiment is a modified embodiment of the first embodiment.

[0049] Compared with the first embodiment described above, in this embodiment, the liquid leakage detection line 1A includes a supporting component 10A, a conductive component 20A and an outer layer covering component 40A, the conductive component 20A includes a first conductive unit 21A and a second conductive unit 22A, the first conductive unit 21A and the second conductive unit 22A are arranged on the supporting component 10A, and the outer layer covering component 40A is covered on the outside of the first conductive unit 21A and the second conductive unit 22A. In other words, the first conductive unit 21A and the second conductive unit 22A are wrapped by the outer layer covering component 40A, and the first conductive unit 21A and the second conductive unit 22A are spaced apart from each other by the supporting component 10A.

[0050] In this embodiment, the support assembly 10A includes two support frames 11A, two built-in cores 12A and multiple installation areas 13A, wherein the built-in core 12A includes a first core unit 121A and a second core unit 122A, and the two support frames 11A are fixed vertically to each other, so that four installation areas 13A are formed around the support frame 11A, and the first conductive unit 21A, the second conductive unit 22A, the first core unit 121A and the second core unit 122A are installed in the installation areas 13A at intervals. The first core unit 121A and the second core unit 122A are used to improve the support strength of the support assembly 10A.

[0051] In this embodiment, the first conductive unit 21A, the second conductive unit 22A, the first core unit 121A, and the second core unit 122A are placed directly in the installation area 13A.

[0052] Specifically, the two skeleton components 11A are fixed vertically to each other, so that four installation areas 13A are formed around the skeleton component 11A, which are defined as an upper left corner area, an upper right corner area, a lower left corner area and a lower right corner area, wherein the first conductive unit 21A and the second conductive unit 22A are respectively installed in the upper right corner area and the lower left corner area, and the first core unit 121A and the second core unit 122A are respectively installed in the upper left corner area and the lower right corner area. In other possible implementations, the first conductive unit 21A and the second conductive unit 22A are respectively installed in the upper left corner area and the lower right corner area, and the first core unit 121A and the second core unit 122A are respectively installed in the upper right corner area and the lower left corner area. Those skilled in the art should understand that the installation positions of the first conductive unit 21A, the second conductive unit 22A, the first core unit 121A and the second core unit 122A are not limitations of the present invention, and it is only necessary to ensure that the first conductive unit 21A and the second conductive unit 22A are spaced apart from each other.

[0053] It is worth mentioning that in other possible implementations, the number of the support skeletons 11A can also be changed. For example, the number of the support skeletons 11A can also be set to three or five, that is, the support skeleton 11A is set to a Y-shaped triangular deformation or a pentagon, which is not a limitation of the present invention.

[0054] It is worth mentioning that, in other possible implementations, the first core unit 121A and the second core unit 122A may also be replaced by the conductive component 20A, that is, the number of the conductive components 20A is increased, for example, the conductive components 20A are vertically placed in the upper left corner area, the upper right corner area, the lower left corner area and the lower right corner area of ​​the installation area 13A, but this is not a limitation of the present invention.

[0055] In particular, in this embodiment, the outer layer covering component 40A is covered on the outside of the supporting skeleton 11A and wraps the skeleton component 11A, the first conductive unit 21A, the second conductive unit 22A, the first core unit 121A and the second core unit 122A. When the environment where the leakage detection line 1A is located leaks, the outer layer covering component 40A contacts the liquid and absorbs or penetrates the liquid, so that the first conductive unit 21A and the second conductive unit 22A are electrically connected through the liquid to achieve the conductive state.

[0056] The material of the skeleton component 11A is PVDF, FEP, ETFE, PFA, PP, PE or low smoke halogen free, which has good corrosion resistance, chemical stability and mechanical properties, so that the leakage detection line 1A can adapt to different working environments and provide sufficient support strength. In addition, the thickness of the skeleton component 11A can be selected from 0.2mm to 1mm, preferably 0.2mm to 0.5mm.

[0057] The material of the first core unit 121A and the second core unit 122A can be selected from one of aramid fiber, carbon fiber fiber, steel wire, copper clad steel, and ultra-high molecular weight polyethylene fiber. At the same time, in order to better ensure the fire resistance and chemical corrosion resistance, an insulating protective layer can be added outside the optional material. The optional material of the insulating protective layer is PVDF, FEP, ETFE, PFA, PP, PE, XLPE or one of low-smoke halogen-free, so that the first core unit 121A and the second core unit 122A can further improve the supporting strength and tensile strength of the support assembly 10A.

[0058] Similarly, the first conductive unit 21A and the second conductive unit 22A are both formed by twisting 19 tinned copper wires with a diameter of 0.10 mm. The material of the first conductive unit 21A and the second conductive unit 22A can also be one of tinned copper, tinned copper alloy, nickel-plated copper or nickel-plated copper alloy.

[0059] The material of the outer layer covering component 40A is one of the wear-resistant and water-permeable materials such as basalt silk, PPS silk, aramid silk, ultra-high molecular weight polyethylene fiber, PET silk, polyester yarn or nylon silk, and a plurality of wear-resistant and water-permeable materials such as basalt silk, PPS silk, aramid silk, ultra-high molecular weight polyethylene fiber, PET silk, polyester yarn or nylon silk are woven by a weaving machine to form the outer layer covering component 40A. When leakage occurs, its fiber structure can absorb and contain part of the liquid, and this absorption effect can quickly sense the presence of the liquid, thereby improving the detection accuracy of the leakage detection line 1A.

[0060] In another possible implementation of this embodiment, the liquid leakage detection line 1A further includes a braided component 30A, the braided component 30A includes a first braided unit 31A and a second braided unit 32A, the first braided unit 31A and the second braided unit 32A are respectively covered on the outside of the first conductive unit 21A and the second conductive unit 22A. The material of the first braided unit 31 and the second braided unit 32 is a wear-resistant and water-permeable material such as basalt silk, PPS silk, aramid silk, carbon fiber silk, ultra-high molecular weight polyethylene fiber, PET silk, polyester yarn or nylon silk, and the mesh number of the first braided unit 31 and the second braided unit 32 is 11±1 mesh.

[0061] The following is an exemplary description of a method for manufacturing the liquid leakage detection line 1A: Twisting to form a first conductive unit and a second conductive unit; Extruding two mutually perpendicular support frames, wherein a plurality of mounting areas are formed around the support frames; Place a first core unit, a second core unit, the first conductive unit and the second conductive unit in the installation area according to their positions; and An outer covering component is woven on the outer side of the supporting component in a manner of wrapping the supporting component, the first conductive unit, the second conductive unit, the first core unit and the second core unit inside.

[0062] In one possible implementation, after the step of twisting to form a first conductive unit and a second conductive unit, the method further includes: weaving a first weaving unit and a second weaving unit outside the first conductive unit and the second conductive unit in a manner of covering the first conductive unit and the second conductive unit.

[0063] In summary, the leakage detection line 2 can quickly and accurately trigger the leakage detection signal, and the supporting component 10A, the conductive component 20A and the outer covering component 40A of the leakage detection line 1A have a variety of material options, which can be selected according to different detection environments to meet detection needs.
