Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to an optical oil detector. [Prior Art] Optical leak detectors are often used to detect oil leaks in facilities such as underground tunnels and Pits. The oil leak detector uses 2 fiber as the oil sensor (fiber sensor), and its principle is to use the physical properties of the fiber. That is, when the oil leaks on the surface of the fiber, the amount of light leakage increases. The transmission loss also has an increasing nature (for example, refer to 曰本专专专公公公59-20092). For example, the oil leak detector can be installed in the drain to detect oil leaking into the water. An optical oil leakage detector having the above characteristics is as shown in Fig. 7 = its main constituent members include: domain sense Qing 2, whose front end is immersed in the water W in the row: P, and the sensor support member 3, Supporting the fiber sensor 2; f, the flange 5, the grid of the sensor support 3 fixed to the drain groove p: / the lightning up converter 6, is disposed at the other end of the fiber sensor 2 to perform $Electric conversion; monitor 7, connected to converter 6. When the oil leaks into the row and the sister is mixed into the water, the fiber sensor 2 will detect the oil leak, and the ten worker converts the pirate 6 and transmits it to the monitor 7 (for example, httP://W__jp/seihln) Llhtml). In the conventional optical oil leakage detector described above, there is still a tortuosity in the lower gas (the refractive index of light in water is different from the refractive index of light in the air), if the water surface of the water boundary in the drainage channel P The change is drastically 318042 5 1300489 days T 'fiber sensing is crying 9 part of the pain, the two points and the fiber sensor 2 contact air volume increase or decrease. The light leakage of the light 2 described above is detected as a malfunction. In the 4^, it is easy to have a leak. The ratio of the light source to the light source is /% in °. From the drain P to the converter, the Wi' white is set to view the scene. However, due to the special special skills such as handling of the light iron terminal equipment, it is difficult to simplify the problem. In addition, since the bacteria adhere to the optical fiber to sense foreign matter, it is easy to smash the molybdenum bismuth, recognize the fine sputum, and absorb the fiber to detect the malfunction of the crying oil detection, or the early deterioration of the light and iron 硎 state 2 . Provided by:::The developer who has the above problems, the purpose of the present invention is to detect the leak _1 =: ^ =, the erection engineering is simple ' and can prevent the oil detector. Optical function of the early deterioration of the fiber sensor [invention] The main components of the crying optical oil detector include: a floating optical fiber of the above-mentioned drifting device; the light person is irradiated to one end of the optical fiber , :=:, the light emitted from the other end of the optical fiber is converted into an electrical signal; when the oil is attached to the optical fiber, the optical oil detector that leaks oil is detected by the change of the light. According to the invention, the optical fiber and the buoyant of the sensor are floating on the water, because

In the optical oil detector of the present invention, the light-emitting element and the light-receiving member 318042 6 1300489 may be housed in the floater. ... The invention does not need to be used as a conventional oil detector, and the fiber optic sensor is disposed outside the drain, etc., that is, the fiber terminal processing requiring special skills can be preset in the process of the full floater. In addition, if you want to use the oil inspection ',, 彳 "" way, the connection line of the sensor is extended to the converter and it must be installed in the range of the optical fiber sensor (about 20 meters) ) Install the converter inside. In the mechanism of the present invention, since the light-emitting element and the light-receiving element are constructed inside the floater, the connecting wire between the floater and each member only needs ordinary electric winding. Therefore there is no longer a limit on the specific setting of the venue. The main constituent members of the optical oil detector of the present invention include: · floating = two optical fibers fixed to the floating device; optical components that emit light into one end of the optical fiber, and convert the light emitted from the other end of the optical fiber into a light receiving element for an electric signal, comprising: a substrate for supplying electric power to the light emitting element and amplifying an output of the light receiving element; and the light emitting element, the light receiving element, and the substrate are housed inside the floating device to cover the Lu light The element, the light receiving element, and the metal frame of the substrate. According to the present invention, since the metal casing covers the light-emitting element, the light-emitting element, and the substrate, and in combination with the explosion-proof layer, an intrinsically safe explosion-proof structure can be constructed. Therefore, there is no particular restriction on the setting place. In the optical oil detector of the present invention, the periphery of the buoyant can be provided as a spherical curved surface, and the optical fiber is disposed on the spherical curved surface. According to the present invention, since the optical fiber can be attached to the floater while maintaining the proper curvature, it is possible to prevent the problem of an increase in the amount of light leakage 318042 7 Ί 300489 caused by excessive bending of the optical fiber. This service is an optical oil detector that can highlight the protrusion of the outside in %. In the optical oil detector in which the upper part of the above-mentioned money is set to prevent the optical fiber from being damaged by touching an external object, the above floating device can be provided in the state of the second and the above tube The opening σ of the part is sealed to be waterproof: the outer shell of the body, and the weight balance of the floater floats on the liquid surface, and the water line is located at a position slightly below the δ邛 of the lid body and the tube portion. /, = Shuming, the junction of the money section of the tube (4) This 'can reduce the possibility of seeping into the interior of the floater. The float is near the top of the floater, that is, most of the float is more;::rr, floating The device is maintained in a stable occlusion state. = type, the system will be set in the floating (four) ^ = = center of gravity at the bottom. Therefore, it is more able to maintain a stable and not inclined mountain. The adjacent side == the bottom of the part, so it becomes a downwardly narrowing of the miscellaneous shape, making it more sorrowful. Therefore, the center of gravity of the floater is similarly achieved as described above for maintaining a stable bite of the floater: in addition, the optical filter of the present invention is additionally provided with a sterilization mechanism = a fungus attached to the optical fiber, etc. Also. π Drilling According to the present invention, since bacteria or foreign matter does not adhere to the optical fiber which is peeled off, it is possible to prevent the detection of the oil leakage operation error or the early deterioration of the fiber sensor. According to the present invention, since the sensor is made of a floating type, the sensor: the water surface: maintains a certain relationship between the positions, even if the liquid level changes rapidly = the leakage side 1 does not increase or decrease accordingly Appropriate and stable detection of leaks / : and 'when placed in equipment such as sinks, no special terminal erection works are required: an optical oil detector can be installed with a simple installation procedure. 'Because of the built-in optical/electrical conversion function in the buoyant, the optical fiber terminal that needs the second= can be processed, all in the floating device process in the factory. Generally, only the optical cable can be set on the site, and the connection mode between the optical cables Early, so the erection of the site was greatly simplified. Gong & Because the floating 11 has a built-in light/electric conversion function, the 42=Γ: function will be limited according to the labor safety guard (4), but the invention is based on the metal. Piece, light-receiving element and substrate, plus explosion-proof layer, = can be = cost-safe explosion-proof structure. Since the invention has the limitation of the work of explosion-proof=field non-fork setting, it can be applied to all the fiber-optic sensors of the fiber-optic sensor that need to detect the oil leakage, and is used in the state of being peeled off, but it is capable of removing and adhering due to m ::: Force does not: on the fiber optic sensor, so the second = two sets, and the life of the fiber optic sensor is longer. & The following 'details' will be described with reference to the drawings to implement the invention.

The optical fiber connector 43A is fixed to the connector 43B on the cover body #18b; and the optical fiber connector 4乜 is fixed. The connector 44B on the cover body. The inside of the cover 18b (inside the floater 17a) is provided with a light-emitting element (LED) 34 connected to the connector 43B, and a light-receiving element (LED) 35 connected to the connection crying. The light-emitting element 34 and the light-receiving element are electrically connected to the substrate 19 by wiring. The optical cable 25 connected to the monitor 7 is also affixed to the cover 18b with ease of attachment/wearing. The action of the aperture 25 is transmitted from the outside to the substrate 19, and the output of the light receiving element 35, which is converted into an electrical signal, is transmitted to the monitor 7. The light-wound clip 56 disposed at the center of the cover 18b is provided with a light-wound clip 56 at the center of the cover 18b, and the light-wound 25 can be fixed to the cover body l8b in an easily disassembled/installed manner, and the light is fixed by the cable clamp 56. The substrate 19 inside the floater 17a is electrically connected. The optical fixture 58 is bolted to the tubular portion 18a of the outer casing 18 and the lid 18b to be fixed to the body 18b. The cable fixture 58 can clamp the light around 25 to see the light, see 25. By means of the cable fixing member 58, the wiring direction of the optical cable 25 can be fixed, and the center of gravity 20 is used to adjust the center of gravity so that the floating device 17a is not tilted due to the weight of the light winding 25 itself. The screw is passed through a porous copper sheet (sterilization mechanism) 38 and inserted into the screw hole 18f, so that the porous copper sheet (sterilization mechanism) 38 is mounted on the guiding portion i8d, and the optical fiber sensation 42 may be adhered to bacteria or foreign matter. The wrong action that causes the optical transmission loss to be large and the normal condition is misjudged as the oil leakage condition. Furthermore, the fiber core itself may be deteriorated in advance due to the intrusion of the attached object. Therefore, the copper 38 is attached to protect the optical fiber sensor 42, and the bacteria are quickly killed by the action of a trace amount of copper, thereby preventing the adhesion of bacteria. Then, the plastic cover 39 is attached to the 锢 ^ ^ 咕 咕 隹 隹 隹 38 38 38 38, and the sterilizing agent can be contained inside. Next, the detailed composition and configuration of the fiber sensor 42 will be described. The fiber optic sensor 42 is such as the 2nd R--- η meat # φ 丨 丨 her 4 brother 2 map does not, in the entire specific detection range ^ WL ^ _ LT ^ ^ (first heart line), the detection range is covered The water is placed up and down, and the optical fiber sensor 42 is exposed to the air, and the direct contact with the floating liquid surface of the foreign body is directly arranged to be extremely wide. Therefore, it can be: = short, the oil component below the water level WL, and the oil leaking to measure a certain thickness contained in the turbid water, and the liquid surface can quickly detect the leak 318042 13 1300489 oil. Further, the water level WL is placed on the upper portion of the floater 17a, i.e., it can maintain the stable and non-tilted state as described below. _ Figure 6 shows a detailed enlarged view of the fiber optic sensor 42. As shown in the figure, fiber optic connectors 43A, 44A are disposed at both ends of the fiber optic sensor 42, and the connector 43B coupled to the connector 43A is attached to the light-emitting element 34; the connector 44B coupled to the connector 44A is attached. It is disposed on the light receiving element 35. The optical fiber sensor 42 can be attached to or removed from the light-emitting element 34 and the light-receiving element 35 by the connector 43 to the connector 44β. Next, a portion of the connector 43 and the connector 44A attached to the end of the optical fiber sensor 42 will be described. The components of the connectors 43A, 44A include: assembly $45, protective tube 46 and female threaded portion 47. The fiber 1 is pulled out from the end of the connector for a specific length, and the cylindrical fitting 45 is inserted into the fiber sensor 42 to make the fiber 10 © 胄. At the end of the skirt fitting 45, a rubber protective tube is coated around the end of the fitting 45 of the longitudinal direction of the optical fiber sensor 42, so that the optical fiber detector 42 is not damaged by bending at the end of the fitting. The female thread portion 47 is attached to the fitting 45$ portion of the opposite side of the protection f 46 (i.e., the end portion of the optical fiber sensor 42). The female screw portion 47 is rotatably movable only in a limited range of the axial direction, and is engaged with the fitting member. The connector 43B of the light-emitting element 34 and the connector 44β of the light-receiving member are represented by a cross section. The front end of the connecting H 43B is provided with a male thread 48, and the front end of the connector 44β is «the male thread 48, 48', and a wide hole 49, 49, α for accommodating the front end of the fitting 45 is provided on the inner side of the connector. To accommodate the fiber, the narrow 318042 14 1300489, 50, 50. The cover body 18b is provided with a hole ceremony ^, the hole 5i 5i, = on the opposite side of the male thread 48, 48, and the above narrow hole 5〇, 5〇, connected for $ for component insertion. Insert the collars 52, 52 into the holes 51, 51. The outer diameter of the collars 52, 52 is the same as the outer diameter of the hole 5151. The outer diameter of the ring 52' is the same as the outer diameter of the light-emitting element 34 and the light-receiving element 35. Then, the light-emitting element 34 and the light-receiving element 35 are inserted into the collar 52 52, and the x-axis 52, 52 is made of synthetic resin. When the electrical insulation is made, it is useful for zero insulation of light, etc. when inserting the light 70 and the fork light 35. The connectors 43A, 44A are bonded to the connectors 43B, 44. B, the fiber core and the wire 1〇 at the front end of the optical fiber sensing 11 42 marked with a point R and a line are inserted into the narrow hole, and the female screw portion 47 and the male screw 48, 48 are screwed together, so that the front end of the fitting 45 is abutted. The wide holes 49, 49 are placed, and the bottom is tightened. Thus, the distance between the front end of the optical fiber 1G in the narrow holes 5G, 5G' and the front end of the light-emitting element material: the optical element 35 is set to an ideal distance. In order to enable the light of the illuminating element φ...34 to be effectively incident on the core 1〇, the pitch χ should not be too large. For example, when the diameter of the light-reducing line 1 〇 is 1. 2 mm, the connector “a, (44A, 44B) is set in the range x is 〇.2 and then 〇4 is within the range. Further, the state in which the floating optical oil detector 17 of the present invention is placed will be described with reference to Figs. 4 and 5 . The front end of the link 60 of the floater 17a is rotatably fixed to the hole 57 of the guide portion 18e (see Fig. 3). The other end of the connecting rod 6 is pivoted by the side wall 63 of the side wall of the draining groove P so that the rotating shaft can be vertically rotated in a direction which is perpendicular to the extending direction of the transverse connecting rod 6 (). In this way, the change of the water level WL (water level (10) to water level wL2) in the water level of the drainage channel P is traced by 318042 15 1300489. Moved to the 60a, 6〇b, 6〇c夂 士 4曰 by Fubei Ma stainless steel, three rods interconnected. Each of the rods is connected 61, and the core-stretchable optical cable 25 is clamped on the connecting rod 6 to guide the extended light 7 from the floating ram 25 to the far-reaching w i7a. The private hunter wall is connected to the monitor. The computer can also be set up to be able to properly connect to the supervisor 1 to collect information. (In the actuating state, the floating optical oil 42 of the present invention is composed of the optical fiber sensor 42 that first enters the effluent and passes through the light receiving light, The output of the light receiving element 35 is amplified by the path provided by the substrate 19, and then transmitted to the monitor 7 via the optical gauge 25. When the detection range of the optical fiber sensor 42 is within the detection range of the optical fiber sensor 42, the light amount of the light receiving element is reduced. The signal on the monitor 7 is lower than a certain amount and is low. Therefore, an alarm signal indicating an abnormality is generated on the monitor 7. Here, when the water level W changes, the floating cry 17a in the floating state is followed by the water level change. Moving, so the water surface and the fiber optic sensor maintain a certain positional relationship. That is, according to the floating optical oil detector 本 of the present embodiment, since the optical fiber sensor 42 is disposed in the floater 17a, the optical fiber sensor 42 and The water surface always maintains a certain positional relationship. Even if the water level changes rapidly, it does not have the 318042 16 1300489 dimming loss, and it can reliably stabilize the oil leakage in the side water. Moreover, it can be installed on equipment such as the existing water tank. When the detector is used, it is not necessary to perform any special operation, and a simple setting step is required. , ', - 纟 Inside the floater na: a light-emitting element 34; a light-receiving element 35 that converts an optical signal into an electrical signal; The substrate 19 is provided with an amplifying circuit for amplifying the signal. Therefore, it is not necessary to set the optical fiber sensor as the outer side of the Jc groove p. That is, the terminal processing of the optical fiber sensor requiring special skills can be all The process of the work is preset in the process of the work, and the installation of the site only needs to set up the wiring of the light and cable 25 for #. Therefore, the m operation is quite simple. In addition, in the past, the fiber sensor was extended to the converter 6 On the laying day I, the converter 6 must be provided within a range (about 20 m) in which the optical fiber sensor can be mounted. However, in the present embodiment, the light receiving element 35 having the function of the converter 6 and the substrate 19 are placed in the floating device J. Inside the 7a, it is no longer subject to the setting field, and even if it is difficult to make the oil leakage point, the _conversion state can be set in the range, and the oil leakage sensor can also be installed. Since the interior of the floating device 17a is provided: Element 34; turning the optical signal The light-receiving element of the electrical signal and the substrate 19 for amplifying the signal of the signal are provided. Therefore, according to the regulations of the Japanese Labor Safety and Health Act, the setting field has certain restrictions, however, since the light-emitting element 34 is used. Further, the optical element 35 and the substrate 19 are housed in the metal casing 23, and a combination of explosion-proof layers is added, and the safety explosion-proof structure can be considered as being safe from the installation site. The figures are shown in Figs. 4 and 5. In the erected state, since the link 6〇17 318042 1300489 limits the lateral movement range of the floater 17a, the floater 17a can be prevented from hitting other machine types or walls. Since the cable 25 is clamped on the link 60, the floater 17a can be prevented. The verticality of the floater 17a is maintained due to the inclination of the imminent liquid level change and the weight of the cable 25 itself.

P ^ "Because the weight balance of the floater 17a is set such that the water level WL is only slightly below the cover 18b' @ this joint portion of the tubular portion and the cover body is always in a liquid state. Therefore, it can be lowered The water seepage into the floater m is pure, and the floating H 17a is maintained in a good (four) waterproof state. And since the water level WL is located at the upper part of the floater 17a, and the center of gravity of the heavy cry falls below, the floater m can be maintained. A stable vertical icy state, that is, when the floater 17a is tilted, (iv) rapidly recovers to a vertical state by buoyancy. = Since the weight of the ballast 2 is fixed at the position of the cylinder (water direction) 'Therefore, the floating device 17a can be set to the vertical posture.

In order to reduce the taper shape, the more the upper portion is maintained, the lower the temperature can be lowered, and the stable vertical posture of the ice trap 17a is also paid as described above. 318042 18 1300489 匕4: It is not limited to the above embodiment. Without departing from the invention Meaning = Γ, can be added, omitted, replaced and other Ai is added to the components. For example, the following modifications can be considered. 3 J Tian redundancy in the above embodiment 'is a plastic single-core fiber, also '=(4) glue fiber is used as the material f of the photodetector 42, and quartz fiber composed of a plurality of core wires is used as the fiber sensor 4. (2) The shape of the floating crucible 17a is not limited to the above embodiment As long as the vertical posture can be maintained, as shown in the above embodiment, since the spherical curved surface is provided, it is easy to erect light with a curvature larger than (four). (3) In the above embodiment, the annular substrate is used. 19 is housed in the outer casing 18 in a horizontal shape. However, in addition to the above-described manner, the substrate 19 may be formed in a rectangular shape and housed in the outer casing 18 in a vertical posture. (4) In the above embodiment, as shown in Fig. 2, the optical fiber is sensed. The detector 42 is arranged around the periphery of the floater in the vertical direction of the drifter 17a, but the arrangement (surrounding mode) of the pair of floaters 17a of the optical fiber sensor 42 is not limited to this mode. (5) Form As shown in Fig. 2, the detection range of the oil is set at one side of the fiber sensor 42 located on the floating device 17a, but the detection range is not limited thereto. It can be in accordance with the floating optical oil detector. The use conditions may be set on both sides or the lower side of the floater 17a. (6) In the above embodiment, the material of the sterilization mechanism is selected from the copper sheet 38, but a silver sheet or a titanium sheet may be used as the sterilization mechanism. (In the above embodiment, the floating optical oil detector 318042 19 1300489 Π uses the link 6G to erect the floating optical oil seal 17, and the floating device can also be used with a soft rope. 17a is associated with the wall use panel 63 so that the floater 17a does not flow. In addition, it is also possible to arbitrarily set the field, and the floating optical oil detector 17 is placed only in a state of floating surface, instead of being fastened to the fixture. (8) The state of use of the floating (four) learning oil detector 17 is not just the liquid level in the drain. For example, it is also conceivable to place the floater i7a on the ground to detect oil leakage. At this time, the detection range is set to the lower side of the floater to detect the oil leakage on the drain floor. That is to say, the floating type optical type is characterized by having a sea surface structure, but its use state is not limited to the state of floating on the water. The present invention is not limited by the above description, but is limited only by the scope of the (4) patent. [Industrial Applicability] The present invention relates to an optical oil detector that detects a change in light leakage & quantity when oil is attached to an optical fiber. The components of the invention include: a buoyant; a solid: two = ^ One, a light-emitting element that causes light to enter the fiber-side end of the optical fiber: 攸, ',,, and the other end of the light is converted into an electrical signal. According to the optical pick-up, mesh, and 丨# m ^ of the present invention, the state of the oil is measured, and the sensor is made of a floating type, and the position of the water surface is maintained at a certain position, even in the impetuous water. There is no need to increase or decrease, and it is possible to accurately detect the equipment such as the water tank. No special amount is required.
