Description

Technical Field

[0001] This invention relates to the field of leakage current detection technology, specifically to a fiber optic cable leakage current detection device. Background Technology

[0002] With the rapid development of communication technology, optical cables are being used more and more widely in communication networks. However, due to the special structure of optical cables, leakage faults will seriously affect the normal operation of communication networks. Therefore, it is crucial to quickly and accurately detect leakage faults in optical cables to ensure the stable operation of communication networks. A device that can automatically detect leakage faults in optical cables has important practical value and social significance.

[0003] Existing fiber optic cable leakage detection technologies have several significant shortcomings and drawbacks. First, traditional detection equipment is typically designed for a single function, lacking flexibility and adaptability to different environments. This can cause significant inconvenience in outdoor or complex terrain settings. Second, existing detection equipment rarely considers the physical burden on operators during operation. Prolonged detection work often requires bending over or reaching high, which not only increases physical exertion but may also lead to worker fatigue and occupational injuries. Furthermore, once a leakage or damage point is detected, existing repair tools usually require manual operation, which is not only inefficient but also cannot guarantee the repair effect. In severe cases, delayed repair may even exacerbate the damage. Finally, the protection and storage of conventional detection equipment when not in use is also a major problem. Traditional equipment often lacks effective protective measures and is easily damaged during storage and transportation, reducing the equipment's lifespan and reliability. Summary of the Invention

[0004] This invention proposes an optical cable leakage current detection device, which solves the problems of limited detection methods and poor protection effects in related technologies.

[0012] As a preferred embodiment of the present invention, an emergency protection structure is fixedly installed on the detection box. The emergency protection structure includes a detector, which is installed inside the detection box. A telescopic groove is opened inside the detection box. A protective plate is slidably connected inside the telescopic groove. A pull block is fixedly installed on the top of the protective plate. A fixing groove is opened inside the protective plate. A plurality of compression springs distributed at equal intervals in a linear array are connected between one side of the protective plate and the side wall of the telescopic groove.

[0013] As a preferred embodiment of the present invention, the inside of the detection box is slidably fitted with two symmetrically arranged support rods, and the top of each of the two support rods is fixedly provided with two symmetrically arranged force-bearing rods. The inside of the detection box is provided with four rectangularly arranged circular holes.

[0014] In a preferred embodiment of the present invention, the force-bearing rod is slidably connected inside the circular hole, and the bottom of both support rods is connected to the inner wall of the detection box by a lifting spring. An inclined pressure rod is fixedly provided on one side of each of the two support rods, and an inclined push block is slidably provided on the inclined surface of the inclined pressure rod.

Both the first and second cleaning racks are meshed with the cleaning gear.

[0016] The working principle and beneficial effects of this invention are as follows:

[0017] 1. This invention utilizes a deformation detection component and other structural features. By pulling a trigger rod, the invention achieves three detection modes. First, pulling the trigger rod upwards drives two unfolding gears and a deformation connecting rod to rotate via a transmission rack and trigger rack, simultaneously causing four electric adjusting rods to rotate 90°, thus achieving the first detection mode. Continuing to pull the trigger rod further deforms it upwards, driving the cooperating gear and ejection gear to rotate. At this point, the waist support plate is pushed out of the detection chamber. The operator then places the retractable shoulder strap on their shoulder and holds the waist support plate against their waist, thus achieving the second detection mode. In the first state, mainly used for outdoor field testing, the testing personnel need to carry the testing equipment with them because the roads are uneven. After finding the leakage location, continue to pull the trigger rod upward. At this time, the pull rod moves upward under the action of the trigger rod, and at the same time, it drives the two top blocks to retract through the inclined pull block. At this time, the automatic repair device is released from the limit of the testing box. The testing personnel can remove the repair device and repair the leakage part of the cable. This is the third state, the repair state. Through the detection deformation component, the testing equipment can adapt to different testing scenarios and improve its practicality. It can not only detect the leakage location, but also repair the leakage location.

[0018] 2. This invention, through its emergency protection structure and other structural features, ensures that during the testing process, if the equipment falls from a height or rolls due to impact, when the testing box rolls to face down, any one of the four force-bearing rods will be squeezed and pushed upon contact with the ground, causing the fixed support rod to move. At this time, the inclined push block is pushed by the inclined pressure block, lifting the fixed block stuck in the telescopic groove upwards. The protective plate is then quickly pushed back to its original position by several lifting springs. The protective plate is made of shock-absorbing material, providing excellent protection and effectively preventing the testing instrument from being damaged during a fall. The emergency protection structure achieves automatic protection.

[0019] 3. This invention, through its active cleaning device and other structural design, ensures that when the transmission rack moves upward, it simultaneously drives the first cleaning rack upward. The second cleaning rack and the fixing ring move downward under the drive of the cleaning gear. Because the cleaning brush is slidably connected inside the spiral groove, it rotates along the spiral groove as it moves downward. Furthermore, since the detection head is located in the middle of the cleaning brush, and the cleaning part of the cleaning brush contacts the detection head, the detection head is cleaned simultaneously when the cleaning brush rotates. Moreover, the detection head is automatically cleaned before each use and after each test, thereby improving the accuracy of the detection head and reducing the workload of the operator.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] like Figures 1-5 As shown, this embodiment proposes a fiber optic cable leakage current detection device, including a detection housing 4. A deformation detection component 1 is fixedly installed inside the detection housing 4. The deformation detection component 1 includes a trigger rod 111 and an automatic repair device 124. The trigger rod 111 is slidably mounted inside the detection housing 4. Three equally spaced slots 117 are formed inside the trigger rod 111. A positioning rod 128 is slidably mounted inside the detection housing 4. A push-out spring 115 is sleeved on the outside of the positioning rod 128. Both ends of the push-out spring 115 are fixedly connected to the inner wall of the detection housing 4 and the positioning rod 128, respectively. The inside of the detection box 4 is provided with a storage slot. Inside the storage slot, two symmetrically arranged deformation connecting rods 104 are rotatably installed. Two symmetrically arranged return torsion springs 102 are connected between the deformation connecting rods 104 and the storage slot. Two symmetrically arranged electric adjusting rods 101 are fixedly sleeved on the outer circumference of the two deformation connecting rods 104. The electric adjusting rods 101 are divided into a fixed part and a telescopic part. The fixed part is fixedly set on the deformation connecting rod 104, and the telescopic part is rotatably installed with a universal wheel 103. The outer circumference of the two deformation connecting rods 104 is fixedly sleeved with a one-way bearing.

[0039] like Figures 2-5As shown, a fixed rod 112 is slidably mounted inside the detection box 4. A transmission rack 105 and a trigger rack 106 are fixedly connected to the left and right ends of the fixed rod 112, respectively. The top of the trigger rack 106 is fixedly connected to the bottom of the trigger rod 111. The transmission rack 105 is meshed with one of the unfolding gears 116, and the trigger rack 106 is meshed with the other unfolding gear 116. A transmission rod 118 is rotatably mounted inside the detection box 4. A cooperating gear 113 and an ejector gear 110 are fixedly sleeved on the outer circumference of the transmission rod 118, respectively. An ejector rack 109 is slidably mounted inside the detection box 4 and meshes with the ejector gear 110. A waist support plate 108 is slidably mounted inside the detection box 4. One end of the ejector rack 109 is fixedly connected to one side of the waist support plate 108. A retractable shoulder strap 123 is provided on the detection box 4.

[0040] like Figures 2-6 As shown, the trigger rod 111 has a straight groove inside, and a pull rod 119 is slidably connected inside the straight groove. A card plate 125 is fixedly installed on the detection box 4. The automatic repair device 124 has a pre-positioning groove inside. The pre-positioning groove and the card plate 125 have the same shape and size. A disassembly block 107 is fixedly installed on the detection box 4.

[0041] like Figures 3-6 As shown, a diagonal pull block 121 is slidably assembled inside the disassembly block 107. The top of the diagonal pull block 121 is fixedly connected to the bottom of the pull rod 119. A part of the pull rod 119 passes through the disassembly block 107. Inclined moving grooves are provided on the inclined surfaces at both ends of the diagonal pull block 121. Diagonal sliding rods 122 are slidably connected inside the moving grooves. A top block 120 is fixedly connected to one end of each of the two diagonal sliding rods 122. The top block 120 is slidably assembled inside the disassembly block 107. A second spring 127 is connected to the inner wall of the top block 120 and the disassembly block 107. A first spring 126 is connected between the inner walls of the diagonal pull block 121 and the top block 120.

[0042] In this embodiment, during the leakage current detection process, because the optical cable is arranged in different locations, the detection process needs to be carried out not only indoors but also outdoors and even in the field. Therefore, by setting the detection deformation component 1, the detection equipment can adapt to different detection environments. First, the detection device has a box structure. When there is no detection need, the box does not take up space and is convenient for storage and transportation. The detection head 301 is retracted and placed inside the protective shell 308. When detection is needed, the detection head 301 needs to be pulled out of the protective shell 308. If the detection is carried out indoors or on a flat road surface, the top of the detection box 4 can be adjusted. When the trigger rod 111 is pulled upward, it moves upward and simultaneously drives the trigger rack 106 and the transmission rack 105 to move upward together. The two unfolding gears 116 simultaneously drive the two deformation connecting rods 104 to rotate. At this time, the return torsion spring 102 connected to the deformation connecting rod 104 twists and deforms, accumulating energy. When the slot 117 on the trigger rod 111 moves to the side of the positioning rod 128, the positioning rod 128 will be ejected into the slot 117 under the action of the ejection spring 115. It should be noted that three slots are arranged in a straight line at equal intervals inside the trigger rod 111. 117, corresponding to three detection modes, one end of the positioning rod 128 is inclined and the inclined surface is set downward, so when the trigger rod 111 moves upward, the positioning rod 128 will not affect the movement of the trigger rod 111, and at the same time will limit the trigger rod 111, so that the trigger rod 111 will not slide downward actively. At this time, the four electric adjusting rods 101 are driven to rotate 90° through the two deformation connecting rods 104, and the four universal wheels 103 simultaneously contact the ground to achieve the support effect. In addition, the height of the electric adjusting rod 101 can be electrically adjusted. The model of the electric adjusting rod 101 is B(32)TL. The electric adjustment rod 101 is equipped with a motor and a transmission mechanism. When the height needs to be adjusted, the detector 211 sends a signal to the motor. When the motor receives the signal, it will rotate and transmit the rotation to the telescopic part through the transmission mechanism, thereby changing its length. It can be adjusted according to the operator's height and the actual detection environment. After the height is adjusted, the detection box 4 can be pushed to move while detection is being performed, which improves the operator's detection comfort and detection efficiency. This is the first detection mode of the detection equipment, which allows the operator to avoid bending over or reaching too high, reducing physical burden and improving detection comfort.

[0043] Furthermore, if the leakage current detection device is moved outdoors, or if the field road surface is uneven and the detection device cannot be moved by the universal wheel 103, the trigger rod 111 is pulled upwards again. At this time, the trigger rack 106 and the transmission rack 105 will both separate from the unfolding gear 116. At this time, the reset torsion springs 102 connected to both ends of the two deformation connecting rods 104 release the stored energy, causing the deformation connecting rods 104 to rotate and reset. The four electric adjusting rods 101 are retracted into the storage slot. During the upward movement, the transmission rack 105 meshes with the cooperating gear 113, driving the cooperating gear 113 and the transmission rod 105. 18 and ejector gear 110 rotate simultaneously. Ejector rack 109 pushes waist support plate 108 under the action of ejector gear 110. Ejector rack 109 pushes waist support plate 108 to extend, providing support for the operator. At this time, positioning rod 128 is located inside the second pull groove. Then, the inspector pulls out the retractable shoulder strap 123 and hangs it on the shoulder, and puts waist support plate 108 against the waist to improve support and comfort. At this time, the inspection equipment is in the second inspection mode, which is mainly suitable for rugged ground and outdoor inspection, improving the mobility and adaptability of the equipment, and ensuring effective inspection under different terrain conditions.

[0044] Furthermore, after the detection head 301 detects the location of the optical cable leakage, the operator confirms the specific leakage point and cleans it. Then, the cause of the leakage is checked. If it is only minor external damage such as a broken rubber protective sleeve on the optical cable, the trigger rod 111 is pulled upwards. At this time, the bottom of the pull rod 119 is in contact with the bottom wall of the straight groove, so pulling the trigger rod 111 upwards will simultaneously move the pull rod 119. The pull rod 119 then moves the inclined pull block 121 upwards. Because inclined sliding grooves are provided on both sides of the inclined pull block 121, when the inclined pull block 121 moves upwards... When the device is in motion, the inclined sliding rods 122, which are slidably installed inside the two inclined grooves, will also retract and move simultaneously, and drive the top block 120 to move together. After the top block 120 separates from the positioning groove of the automatic repair device 124, the automatic repair device 124 is no longer limited by the disassembly block 107. The operator can directly remove the automatic repair device 124 and repair the leakage point through the automatic repair device 124. This is the third form of the detection device, the leakage point repair form, which not only improves the inspection efficiency, but also reduces the further damage to the optical cable or safety risks that may be caused by delay.

[0045] In addition, after the optical cable repair is completed, the positioning slot-aligning clamping plate 125 on one side of the automatic repair device 124 is first inserted. At the same time, the disassembly block 107 is also inserted into the insertion slot on the automatic repair device 124. The two top blocks 120 are ejected into the top slot under the action of the second spring 127 to achieve the limiting effect. The clamping plate 125 is used for pre-positioning, and the two top blocks 120 are used for limiting, ensuring a stable connection between the detection box 4 and the automatic repair device 124. Then, the positioning rod 128 is pulled outward, and then the trigger rod 111 is pushed down. During this process, the deformation gear meshes with the cooperating gear 113 again and drives it to rotate in the opposite direction. The waist support plate 108 retracts back into the detection box 4. When the trigger rack 106 and the transmission gear When the strip 105 is engaged, the two unfolding gears 116 will also rotate simultaneously. However, the two unfolding gears 116 are connected to the deformation connecting rod 104 through a one-way bearing. Therefore, when the two unfolding gears 116 rotate in opposite directions, they will not drive the deformation connecting rod 104 to rotate. At this time, the detection equipment returns to its initial state, which is convenient for transportation and storage. It also effectively protects the core components of the detection equipment, avoids damage caused by the external environment, and extends the service life of the equipment. Through the above-mentioned deformation components, the leakage current detection equipment achieves a high degree of functional integration and environmental adaptability, providing a flexible and efficient solution to meet the needs of on-site testing personnel in different environments, reducing testing time, reducing the labor intensity of operators, and improving the accuracy of detection and repair.

[0046] It should be noted that the automatic repair equipment 124 consists of a heating device and an injection device. The main equipment is filled with molten optical cable repair adhesive. During repair, the optical cable clamps 114 are first opened and clamped to hold the optical cable body. The optical cable clamps 114 are rotated and mounted on the automatic repair equipment 124. The automatic repair equipment 124 is then started to inject the optical cable repair adhesive onto the surface of the damaged part of the optical cable. The drying device inside the automatic repair equipment 124 is then started to dry the optical cable repair adhesive. At this point, the repair is complete. It should be noted that this repair equipment can only repair damaged parts of the plastic outer shell of the optical cable. In cases of more serious damage, repair must be performed by professional repair personnel.

[0047] Example 2

[0048] like Figures 7-10As shown, based on the same concept as in Embodiment 1 above, this embodiment also proposes that an emergency protection structure 2 is fixedly installed on the detection box 4. The emergency protection structure 2 includes a detector 211, which is installed inside the detection box 4. A telescopic groove is provided inside the detection box 4, and a protective plate 203 is slidably connected inside the telescopic groove. A pull block is fixedly installed on the top of the protective plate 203, and a fixing groove 209 is provided inside the protective plate 203. Several compression springs 204 distributed at equal intervals in a linear array are connected between one side of the protective plate 203 and the side wall of the telescopic groove.

[0049] like Figure 9 As shown, the inside of the detection box 4 is fitted with two symmetrically arranged support rods 201. The top of each support rod 201 is fixed with two symmetrically arranged force-bearing rods 202. The inside of the detection box 4 is provided with four rectangular circular holes arranged in a row.

[0050] like Figures 7-10 As shown, the force-bearing rod 202 is slidably connected inside the circular hole. The bottoms of the two support rods 201 are connected to the inner wall of the detection box 4 by a lifting spring 205. An inclined pressure rod 206 is fixedly installed on one side of each of the two support rods 201. An inclined push block 207 is slidably installed on the inclined surface of the inclined pressure rod 206. Both ends of the inclined push block 207 are inclined. A fixing block 210 is slidably installed inside the detection box 4. A slider 208 is fixedly installed on the top of the fixing block 210. The fixing block 210 and the fixing groove 209 have the same shape and size.

[0051] In this embodiment, before the testing equipment performs the test, the protective plate 203 needs to be pushed to one side to expose the detector 211 underneath. The testing personnel need to adjust the detector 211 to test the optical cable. At the same time, the fixing block 210 needs to be inserted into the fixing groove 209 to achieve the automatic positioning effect of the protective plate 203. At this time, several compression springs 204 connected to one side of the protective plate 203 are squeezed and undergo elastic deformation. During the testing process, if the testing box 4 falls and the detector 211 faces downward, as long as one of the four force rods 202 contacts the ground, the force rod 202 will receive the impact force and be pushed and retracted into the testing box 4. At the same time, it will drive the support rod 201 fixedly connected to it to move together. The support rod 201 drives the inclined pressure rod 206 to move downward. 06. The inclined surface of the inclined push block 207 is used to push the inclined push block 207 to move towards the side closer to the fixed block 210. The inclined push block 207 is slidably set inside the detection box 4, and the side of the inclined push block 207 close to the fixed block 210 is also inclined. The bottom of the slider 208 is in contact with the inclined surface of the inclined push block 207. Therefore, when the inclined push block 207 moves, its inclined surface pushes the slider 208 and the fixed block 210 to move upward. After the fixed block 210 separates from the fixed groove 209, the protective plate 203 is quickly reset under the push of several compression springs 204. Since the protective plate 203 is made of shock-absorbing and energy-absorbing material, it can effectively protect the detector 211 after it is reset, avoiding damage to the equipment when it falls or rolls. It also prevents the detector from falling from the air or rolling due to collisions during the detection process and breaking the detector 211, thus achieving the effect of active protection.

[0052] Example 3

[0053] like Figures 11-12 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that an active cleaning device 3 is fixedly installed on the detection box 4. The active cleaning device 3 includes a detection head 301 and a protective shell 308. The detection head 301 is installed inside the protective shell 308. A spiral groove 307 is opened inside the protective shell 308. A cleaning brush 309 is slidably connected inside the spiral groove 307. A fixing ring 305 is rotatably installed on the cleaning brush 309. A second cleaning rack 304 is fixedly connected to the top of the fixing ring 305. A straight connecting rod 302 is fixedly connected to the transmission rack 105. A first cleaning rack 303 is fixedly installed on the straight connecting rod 302. A cleaning gear 306 is rotatably installed inside the detection box 4. The first cleaning rack 303 and the second cleaning rack 304 are both meshed with the cleaning gear 306.

[0054] In this embodiment, each time the detection device drives the electric adjusting rod 101 to rotate and support via the transmission rack 105, it simultaneously drives the first cleaning rack 303 to move upward via the straight connecting rod 302. The first cleaning rack 303 then drives the second cleaning rack 304 and the fixing ring 305 to move downward via the cleaning gear 306. The cleaning brush 309 installed at the bottom of the fixing ring 305 also rotates and moves downward accordingly. Because a part of the cleaning brush 309 is slidably connected in the spiral groove 307 opened inside the protective housing 308, during the downward movement of the cleaning brush 309, it rotates and slides downward along the spiral groove 307. The cleaning part of the cleaning brush 309 contacts the detection head 301 installed inside the protective housing 308. Therefore, when the cleaning brush 309 rotates downward, it simultaneously removes dust from the surface of the detection head 301, thus detecting... The head 301 is telescopic. During testing, the head 301 needs to be pulled outwards, and after testing, the head 301 retracts into the protective housing 308. Then, the trigger rod 111 resets. During this process, the first cleaning rack 303 contacts the cleaning gear 306 again, causing the cleaning gear 306 to reverse. During the rotation and reset of the cleaning brush 309, the head 301 is cleaned again. It should be noted that the spiral groove 307 and the second cleaning rack 304 are staggered. During the downward movement of the second cleaning rack 304, there is no movement interference between it and the spiral groove 307. Through the above structure, the function of automatically cleaning the head 301 before and after testing is realized, which improves the testing effect and cleaning efficiency, reduces the workload of manual cleaning, and improves efficiency while reducing labor costs.

[0055] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
