Description

Technical Field

[0001] This invention relates to the field of power distribution network technology, specifically to an intelligent detection device, system, and method for power distribution network safety hazards. Background Technology

[0002] Utility model patent CN222599535U discloses a high-altitude inspection device for power equipment, including a protective frame and an inspection mechanism. The inspection mechanism is housed inside the protective frame, and a locking assist mechanism is provided at one end of the protective frame. This high-altitude inspection device for power equipment, through the arrangement of a handle, integrated ring, mounting slot, camera, lighting, signal transmitter, and battery, allows the device to illuminate the surface of the cable as it moves along the cable. When the cable enters the protective frame through the locking assist mechanism, the battery drives the lighting on the integrated ring to illuminate the cable surface. Simultaneously, multiple cameras capture images of the illuminated cable surface. The captured information is transmitted to the operator's mobile phone via the signal transmitter, enabling the operator to promptly understand the cable damage condition, thereby improving inspection efficiency and facilitating the inspection work.

[0003] However, the above-mentioned patented technologies have the following drawbacks: The protective frame is a non-openable structure, making it difficult to install on certain fixed cables; that is, the protective frame cannot be inserted into the cable from one end. The testing equipment can only test cables, but cannot repair damaged parts of the cables. It requires additional repair tools and operations, which reduces the efficiency of testing and maintenance, and also reduces the safety of testing and repair. Summary of the Invention

The repair assembly includes a repair frame, which is slidably connected to the second housing. The repair frame is connected to the second housing via a spring.

[0005] Optionally, the lifting assembly includes a cylinder and a lifting base, the cylinder being fixedly connected to the repair frame, the lifting base being slidably connected to the repair frame, and the piston rod of the cylinder being fixedly connected to the lifting base. The clamping assembly is provided in two parts, including a wedge plate, a rough plate and a push wheel assembly. The wedge plate and the rough plate are slidably connected to the repair frame. The wedge plate is connected to the repair frame by a second spring, and the rough plate is connected to the wedge plate by a third spring. The push wheel assembly is rotatably connected to the lifting base frame.

[0006] Optionally, the tape bonding assembly is provided in two parts, including a tape output assembly, a pressing assembly, and a cutting assembly.

[0007] Optionally, the tape output assembly includes two unidirectional tape feeding assemblies; The unidirectional tape feeding assembly includes a tape roll core, plastic wheels, a rack, a magnet frame, and a permanent magnet. There are two plastic wheels. The tape roll core and the two plastic wheels are rotatably connected to the repair frame. Insulating tape is wound on the tape roll core. The two plastic wheels clamp the insulating tape. A gear is fixed to one of the plastic wheels. The rack is slidably connected to the lifting base. A permanent magnet and a permanent magnet are fixed to the rack. The magnet frame is fixed to the repair frame, and the permanent magnet is fixed to the magnet frame.

[0008] Optionally, the clamping assembly includes a clamping frame, a first wedge, a pressure cylinder assembly, and a second wedge. The clamping frame is slidably connected to the repair frame and is connected to the repair frame via a fourth spring. The first wedge and the pressure cylinder assembly are both slidably connected to the clamping frame.

The second wedge is fixedly connected to the repair frame.

[0009] Optionally, the shearing assembly includes two blades and two ball-bearing push rod assemblies. The two blades are rotatably connected to the repair frame via a rotating shaft. A wedge block is fixed to the blade. The blade is connected to the repair frame via a spring. The ball-bearing push rod assemblies are fixed to the lifting base.

[0010] Optionally, a processing module is provided inside the housing.

[0011] Optionally, a wireless module is provided inside the housing.

[0012] A smart detection system for safety hazards in power distribution networks includes a control terminal that is wirelessly connected to each other and the smart detection device for safety hazards in power distribution networks.

[0013] A method for intelligent detection of safety hazards in power distribution networks, comprising the following steps, utilizes an intelligent detection system for power distribution network safety hazards to detect cables in the power distribution network: Step 1: Open housing 1 and housing 2 by rotating them relative to each other. After aligning with the cable, rotate housing 1 and housing 2 relative to each other to close and interlock housing 1 and housing 2. The electric drive wheel and pressure wheel assembly clamp the cable. Step 2: Use the control terminal to control the intelligent detection device for power distribution network safety hazards, so that the intelligent detection device for power distribution network safety hazards moves on the cable; Step 3: Use a probe to detect defects in the cable; Step 4: When a defect is found in the cable, repair the defect using the repair kit.

[0014] The present invention has the following beneficial effects: To address the problem that existing testing equipment is difficult to install onto already installed fixed cables, this application provides a housing that can be rotated and opened relative to each other, allowing the device to be quickly fitted onto cables at different locations and locked in place, thus improving the ease of installation and applicability of the equipment.

[0015] To address the problem that existing technologies can only detect cables but cannot repair damaged areas, this application introduces a repair component. After detecting the defect location, a cylinder drives a lifting base to move, bringing the repair mechanism closer to the defect area. The cable is then secured by a clamping component, making the repair process more stable. Simultaneously, the detection and repair mechanisms can operate independently, allowing repairs to be completed without stopping detection, thus improving detection and maintenance efficiency.

[0016] This application improves the reliability of the repair process by setting up a tape output component, using a lifting base to drive the rack and gear to automatically output the insulating tape, and controlling the engagement and disengagement of the tape conveying mechanism through a magnetic structure to prevent the insulating tape from shifting back.

[0017] To address the issue of poor adhesion between insulating tape and cable, this application incorporates a pressing component. This component moves along the outer wall of the cable and presses the insulating tape, ensuring that the insulating tape fully adheres to the cable surface, reducing gaps, and improving the sealing performance of the repair.

[0018] To address the cumbersome manual tape cutting process, this application introduces a cutting component that automatically cuts the insulating tape after repair and utilizes an elastic structure to achieve resetting, thereby improving the automation level of the device.

[0019] In summary, this application achieves automated repair of cable defects after detection through an integrated design of detection, positioning, clamping, adhesive application, and cutting, thereby reducing manual maintenance costs, improving the efficiency of cable detection and maintenance in power distribution networks, and enhancing operational safety.

[0030] A preferred tape bonding assembly configuration includes two tape bonding assemblies, each comprising a tape output assembly, a pressing assembly, and a cutting assembly.

[0031] A preferred tape output assembly includes two unidirectional tape feeding assemblies; The unidirectional tape feeding assembly includes a tape core 20, plastic wheels 21, a rack 23, a magnet frame 26, and a permanent magnet 27. There are two plastic wheels 21. The tape core 20 and the two plastic wheels 21 are rotatably connected to the repair frame 6. Insulating tape 201 is wound on the tape core 20. The two plastic wheels 21 clamp the insulating tape 201. A gear 22 is fixedly connected to one of the plastic wheels 21. The rack 23 is slidably connected to the lifting base 8.

The magnet frame 26 is fixedly connected to the repair frame 6, and the permanent magnet 27 is fixedly connected to the magnet frame 26.

[0032] A preferred clamping assembly is provided, comprising a clamping frame 11, a first wedge 12, a pressure cylinder assembly 14, and a second wedge 15. The clamping frame 11 is slidably connected to the repair frame 6 and is connected to the repair frame 6 via a fourth spring 111.

The second wedge 15 is fixedly connected to the repair frame 6.

[0033] In a preferred configuration, the shearing assembly includes two blades 18 and two ball-bearing push rod assemblies 10. The two blades 18 are rotatably connected to the repair frame 6 via a rotating shaft. A wedge block 19 is fixed to the blade 18. The blades 18 are connected to the repair frame 6 via a spring 181. The ball-bearing push rod assemblies 10 are fixed to the lifting base 8.

[0034] In addition, a processing module is provided inside the second housing 2. A wireless module is also provided inside the second housing 2.

[0035] like Figure 1 As shown, an intelligent detection system for safety hazards in power distribution networks includes a control terminal that is wirelessly connected to each other and the intelligent detection device for safety hazards in power distribution networks.

[0036] like Figure 2As shown, an intelligent detection method for safety hazards in a power distribution network utilizes the aforementioned intelligent detection system for power distribution network safety hazards to detect cables 13 in the power distribution network, including the following steps: Step 1: Open the housing 1 and housing 2 by rotating them relative to each other. After aligning with the cable 13, rotate the housing 1 and housing 2 relative to each other to close and interlock the housing 1 and housing 2. The electric drive wheel 3 and the pressure wheel assembly 4 clamp the cable 13. Step 2: Use the control terminal to control the intelligent detection device for power distribution network safety hazards, so that the intelligent detection device for power distribution network safety hazards moves on cable 13; Step 3: Use probe 5 to inspect cable 13 for defects; Step 4: When a defect is found in cable 13, repair the defect in cable 13 using the repair kit.

[0037] Working principle: Open the housing 1 and housing 2 by rotating them relative to each other. After aligning with the cable 13 to be tested, rotate the housing 1 and housing 2 relative to each other to close the housing 1 and housing 2 and interlock the housing 1 and housing 2. At this time, the electric drive wheel 3 is located above the cable 13 and the pressure wheel assembly 4 is located below the cable 13. The electric drive wheel 3 and the pressure wheel assembly 4 clamp the cable 13.

[0038] The control terminal and the wireless module of the intelligent detection device transmit signals wirelessly, thereby enabling the control terminal to remotely control the operation of various electrical components of the intelligent detection device.

[0039] The electric drive wheel 3 is controlled to rotate, and in conjunction with the clamping and limiting of the pressure roller assembly 4, the intelligent detection device moves on the cable 13, and the probe head 5 detects damage to the outer surface of the cable 13.

[0040] When the probe 5 detects a defect on the outer surface of the cable 13 (an image recognition module or manual identification can be used), the piston rod of the control cylinder 7 extends (automatic control or remote manual control can be achieved using a processing module). The electric drive wheel 3 continues to rotate, and the cylinder 7 controls the lifting base 8 to gradually move upward along the repair frame 6. The push wheel assembly 9 pushes the inclined surface of the wedge plate 16, thereby causing the wedge plate 16 to overcome the elastic force of the second spring 161 and drive the rough plate 17 to move towards the cable 13. After the rough plate 17 and the cable 13 come into contact, the third spring 171 is compressed, thereby causing the two rough plates 17 to clamp the cable 13. After the push wheel assembly 9 moves along the side wall of the wedge plate 16, the wedge plate 16 stops approaching the cable 13.

[0041] As the rough plate 17 clamps the cable 13, the repair frame 6 remains in its current position, while housing 1 and housing 2 continue to move to inspect the cable 13 using the probe head 5, and spring 8 61 is stretched.

[0042] Then, rack 23 moves upward to mesh with gear 22. Gear 22 drives one of the plastic wheels 21 to rotate. Plastic wheel 21 drives the insulating tape 201 to be released from the tape roll core 20, driving the other plastic wheel 21 to rotate. Since the insulating tape 201 has a certain thickness, the insulating tape 201 will not bend excessively. Rack 23 continues to move upward to disengage from gear 22. The insulating tape 201 stops being released. At this time, permanent magnet 1 24 moves to the side of permanent magnet 3 27. Permanent magnet 3 27 magnetically attracts permanent magnet 1 24, causing rack 23 to slide on the lifting base 8 and thus disengage from gear 22.

[0043] The lifting base 8 continues to move upward, pushing the pressing frame 11 to overcome the elastic force of spring 4 111. After wedge strip 1 12 and wedge strip 2 15 come into contact, wedge strip 2 15 pushes wedge strip 1 12 to overcome the elastic force of spring 5 121, causing the pressing cylinder assembly 14 to move towards the cable 13. The pressing cylinder assembly 14 comes into contact with the insulating tape 201, and the two pressing cylinder assemblies 14 press the two insulating tapes 201 together. The lifting base 8 continues to push the pressing frame 11 and the pressing cylinder assembly 14 upward. The two pressing cylinder assemblies 14 move upward along the outer wall shape of the cable 13. The two pressing cylinder assemblies 14 keep pressing the two insulating tapes 201 together, so that the two insulating tapes 201 can repair and stick to the cable 13, reduce the gap between the insulating tape 201 and the cable 13, and improve the repair quality.

[0044] Then the lifting base 8 continues to move upward, driving all the ball-bearing push rod assemblies 10 to move upward. In a shearing mechanism, two ball-bearing push rod assemblies 10 push two wedge blocks 19 respectively, so that the two blades 18 overcome the elastic force of the spring 181 and rotate around the rotating shaft, so that the two blades 18 cut an insulating tape 201.

[0045] Then, the piston rod of the control cylinder 7 shortens, and the blade 18 reverses and resets under the elastic force of spring 7 181. The two pressure cylinder assemblies 14 reset under the elastic force of spring 6 141 and spring 5 121, releasing their contact with the insulating tape 201. The rack 23 moves down and does not mesh with the gear 22, and the plastic wheel 21 does not rotate, preventing the insulating tape 201 on the tape roll core 20 from being stored inside the tape roll core 20. Then, the push wheel assembly 9 disengages from its contact with the wedge plate 16. The wedge plate 16 and the rough plate 17 reverse their movement under the elastic force of spring 2 161 and spring 3 171, releasing the two rough plates 17 from clamping the cable 13. The repair frame 6 reverses and resets under the elastic force of spring 8 61. This achieves the technical effect of repair and inspection not interfering with each other. The electric drive wheel 3 does not need to stop working, that is, the housing 1 and housing 2 do not need to stop for repair, improving the efficiency of inspection and repair.

[0046] When permanent magnet 25 moves down to the side of permanent magnet 3 27, the magnetic repulsion of permanent magnet 3 27 repels permanent magnet 25, thereby causing rack 23 to move along lifting base 8. Rack 23 and gear 22 mesh to facilitate subsequent repair work.

[0047] Beneficial effects of this invention: In addressing the problem that existing testing equipment typically employs an integrated protective frame structure, which prevents it from being opened and installed onto already installed fixed cables 13, thus limiting equipment installation, this application proposes a design with mutually rotatable housing 1 and housing 2. Housing 1 and housing 2 can be rotated open relative to each other, allowing the cable 13 to be placed between them. The housings then rotate to close and interlock, enabling the device to be quickly installed onto fixed cables 13 in different locations, thus improving the ease of installation and applicability of the testing device.

[0048] Existing technologies can only inspect the surface of cable 13 and cannot repair detected damage, still requiring manual maintenance and resulting in low maintenance efficiency. This application addresses this issue by installing a repair component on housing 2, enabling the repair component to move to the defect location of cable 13 based on the inspection results for automatic repair.

[0049] The cylinder 7 controls the movement of the lifting base 8, bringing the repair mechanism closer to the defect location. Simultaneously, the rough plate 17 clamps the cable 13, keeping the repair frame 6 in a fixed position. Meanwhile, housing 1 and housing 2 can continue to move under the drive of the electric drive wheel 3, allowing the inspection and repair mechanisms to operate independently. Therefore, the device can complete the repair without stopping its movement, improving the continuity of cable 13 inspection and overall maintenance efficiency.

[0050] This application employs a tape output assembly. A lifting base 8 moves a rack 23, causing it to mesh with a gear 22 and drive the plastic wheel 21 to rotate. This automatically outputs the insulating tape 201 wound on the tape roll 20, achieving automatic supply of the insulating tape 201. Simultaneously, the magnetic force between permanent magnet 3 27 and permanent magnets 1 24 and 2 25 automatically disengages or engages the rack 23 with the gear 22, preventing the insulating tape 201 from shifting backward.

[0051] To prevent the insulating tape 201 from not adhering tightly to the cable 13, which could easily create gaps and affect the protective effect, this application uses a pressing assembly consisting of a pressing frame 11, a first wedge strip 12, a pressing cylinder assembly 14, and a second wedge strip 15. When the lifting base 8 continues to move, it pushes the pressing frame 11 to move, causing the second wedge strip 15 to push the first wedge strip 12, which in turn drives the pressing cylinder assembly 14 to move towards the cable 13. This allows the two pressing cylinder assemblies 14 to press the two output insulating tapes 201 together and move along the shape of the outer wall of the cable 13, thereby ensuring that the insulating tape 201 fully adheres to the surface of the cable 13, reducing the gap between them and improving the repair sealing performance and reliability.

[0052] To address the problem of cumbersome manual repair processes requiring additional tape cutting, this application proposes a shearing assembly consisting of blades 18, a ball-bearing push rod assembly 10, a wedge block 19, and a spring 181. After repair, the lifting base 8 moves the ball-bearing push rod assembly 10, causing it to push the wedge block 19, which in turn drives the two blades 18 to rotate around a pivot, thus automatically cutting the insulating tape 201. Simultaneously, the spring 181 automatically resets the blades 18, ensuring continuous subsequent inspection and repair work and improving the automation level of the device.

[0053] In summary, this application achieves rapid installation through housing 1 and housing 2, detects cable 13 defects through probe 5, and achieves automatic repair after detection through a repair mechanism composed of repair frame 6, cylinder 7, lifting base 8, clamping assembly and tape application assembly. This links the detection, positioning, clamping, tape application and cutting processes, improves the automation level of power distribution network cable 13 detection and maintenance, reduces manual maintenance costs, improves work efficiency and work safety.
