Description

Technical Field

[0001] This invention relates to the field of power distribution line fault technology, specifically to an isolation mechanism for power distribution line faults. Background Technology

[0002] Distribution network line fault isolation is a new type of hierarchical fault isolation technology for distribution networks. It takes the distribution network as the protected object and achieves layer-by-layer protection against faults by setting up multiple layers of fault isolation walls. The core objective is to ensure the safe and economical operation of the distribution network.

[0003] Currently, fault isolation in power distribution networks mainly relies on layered protection and rapid response technologies to precisely isolate faulty sections when a fault occurs, preventing the impact of the fault from spreading. Existing isolation mechanisms primarily use circuit breakers or knife switches to disconnect power to the lines. However, these mechanisms can only disconnect power to a single faulty line and cannot adaptively extinguish fires that start from a fault. Existing methods for extinguishing fires after power outages mainly use fire blankets or conventional fire extinguishing media, but these methods cannot provide targeted fire isolation and passivation of sharp surfaces on faulty and burning lines.

[0004] In view of this, an isolation mechanism for power distribution network line faults was designed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an isolation mechanism for power distribution network line faults, which can be quickly deployed and used at different line fault points, thereby controlling the fire in a short period of time.

[0006] To achieve the above objectives, the present invention provides an isolation mechanism for power distribution network line faults, including an overhead fault cable, an adaptive clamping mechanism clamped outside the fault cable, an isolation and fire extinguishing mechanism installed outside the adaptive clamping mechanism, a power supply mechanism installed on the isolation and fire extinguishing mechanism, and a medium conveying mechanism installed between the isolation and fire extinguishing mechanism and the power supply mechanism.

[0007] The adaptive clamping mechanism includes a first tray and a third tray; two second trays are inserted into the first tray, and insert rods are movably installed on the outside of the two second trays; a fourth tray is arranged directly above the third tray, and two clamps are fixedly installed on the fourth tray; two sets of outer shells are arranged on the outside of the third tray, and an electromagnet is installed in each set of outer shells. A coil is arranged on the electromagnet, and a permanent magnet is fixedly installed in the clamps.

[0008] Preferably, the first pallet is provided with a clamp, and an end rod is inserted into the clamp, with an auxiliary traction rope connected to the end rod.

[0009] Preferably, the adaptive clamping mechanism further includes two pressure rollers, with two symmetrically distributed limiting discs fixedly installed at both ends of the pressure rollers, and two symmetrically distributed first bearings installed on the rod segments at both ends of the pressure rollers; the outer side of the pressure rollers is provided with evenly distributed teeth.

[0010] Preferably, the fire isolation extinguishing mechanism includes a bottom cover fixedly installed on the outside of the first support plate and the third support plate, a folding cover installed on the outside of the insertion rod and the fourth support plate, and two symmetrically distributed drainage pads and two solid pads installed in the front port and the end port of the bottom cover and the folding cover; the inner wall of the drainage pad has multiple evenly distributed slots.

[0011] Preferably, a sprayer is fixedly installed in the middle of the bottom cover, a ring gasket is fixedly installed on the inner wall of the bottom cover, and a second bearing is installed in the ring gasket and the groove of the inner wall of the bottom cover. A horizontally placed first linkage component is installed in the second bearing. A driving component and a second linkage component are movably installed in the bottom cover. Multiple pressure relief slots are evenly distributed in the arc-shaped shell at the bottom of the bottom cover.

[0012] Preferably, the first linkage includes a shaft and two deflecting gears, the driving member includes a shaft and a wide gear, the second linkage includes a vertical shaft, a gear and a deflecting gear, and the deflecting gear in the second linkage meshes with one deflecting gear in the first linkage, while the other deflecting gear in the first linkage meshes with the wide gear in the driving member.

[0013] Preferably, the energy supply mechanism includes an energy storage module fixed to the bottom cover by a nut, a housing fixedly installed inside the energy storage module, a motor fixedly installed inside the housing, a drive gear installed on the motor, and the drive gear meshing with the gear inside the second linkage component.

[0014] Preferably, the energy storage module has wiring holes on both sides, and a horizontally placed sleeve is installed outside the wiring holes. A photovoltaic module is movably installed at the outer end of the sleeve, and a shield is installed outside the photovoltaic module.

[0015] Preferably, the medium conveying mechanism includes a transfer tube installed in the threaded port at the bottom of the sprayer, an outer cylinder at the bottom end of the transfer tube, and a cap installed at the end of the outer cylinder. Two positioning members are fixedly installed in the inner cavity of the outer cylinder, and a horizontal shaft is movably installed in the two positioning members. An impeller is installed on the outside of the horizontal shaft, and an input pipe is installed in the bottom pipe section of the outer cylinder. One end of the horizontal shaft is installed on the shaft inside the motor.

[0016] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0017] 1. The isolation mechanism for power distribution line faults provided by the present invention can be clamped on the line via magnetic clamping. When there is a fire on the line, the isolation mechanism can be quickly deployed and used along the faulty line at different erection heights by adaptive travel or manual traction. This facilitates efficient loading, unloading and use on the faulty and burning line, thereby controlling the fire on the line in a short time and preventing the fire from spreading.

[0018] 2. It enables rapid fire suppression in the combustion zone and reduces the additional costs and losses required for fire suppression of power lines, thereby achieving effective energy saving.

[0019] 3. While the isolation mechanism extinguishes the fire section by section on the de-energized line, the sharp protrusions formed on the surface of the line due to the fire will be quickly blunted and smoothed before they are fully cured. This ensures the safe recovery of the faulty line by subsequent workers and effectively avoids the risk of safety hazards to workers caused by the sharp protrusions on the surface of the faulty line after it has been cured.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an isolation mechanism for power distribution network line faults.

[0039] Combination Figures 1 to 10As shown, the present invention provides an isolation mechanism for power distribution line faults, including an overhead fault cable 100, an adaptive clamping mechanism 200 clamped outside the fault cable 100, an isolation and extinguishing mechanism 300 installed outside the adaptive clamping mechanism 200, a power supply mechanism 400 installed on the isolation and extinguishing mechanism 300, and a media conveying mechanism 500 installed between the isolation and extinguishing mechanism 300 and the power supply mechanism 400. The adaptive clamping mechanism 200 uses magnetic attraction to facilitate the loading and unloading of the fault cable 100, which enhances the stability of the device as it travels along the fault cable 100. The isolation and extinguishing mechanism 300, in conjunction with the media conveying mechanism 500, inputs extinguishing media to quickly extinguish the fire on the fault cable 100. The power supply mechanism 400 provides continuous power for the device's movement and media input. The media conveying mechanism 500 is used to transfer multiple types of extinguishing media.

[0040] The adaptive clamping mechanism 200 includes a first support plate 210, a third support plate 220, and two pressure rollers 230;

[0041] Two second trays 2102 are inserted into the first tray 210. Insert rods 2101 are movably installed on the outside of the two second trays 2102. A fourth tray 2201 is set directly above the third tray 220, and two clamps 2202 are fixedly installed on the fourth tray 2201. Two sets of outer shells 270 are set on the outside of the third tray 220. An electromagnet 2701 is installed inside each set of outer shells 270. A coil 2702 is set on the electromagnet 2701. A permanent magnet 2703 is fixedly installed inside the clamps 2202.

[0042] The first pallet 210 is provided with a clamp 250, and an end rod is inserted into the clamp 250. An auxiliary traction rope 260 is connected to the end rod. The exposed section of the auxiliary traction rope 260 is easy to pull manually, so that the device can move along the faulty cable 100.

[0043] Two symmetrically distributed limiting wheel discs 2301 are fixedly installed at both ends of the pressure wheel 230, and two symmetrically distributed first bearings 240 are installed on the rod segments at both ends of the pressure wheel 230.

[0044] The outer side of the pressure roller 230 is provided with evenly distributed teeth in the middle.

[0045] The fire isolation extinguishing mechanism 300 includes a bottom cover 310 fixedly installed outside the first support plate 210 and the third support plate 220, a folding cover 320 installed outside the insertion rod 2101 and the fourth support plate 2201, and two symmetrically distributed drainage pads 340 and two solid pads 350 installed inside the front port and the end port of the bottom cover 310 and the folding cover 320.

[0046] The inner wall of the drainage pad 340 has multiple evenly distributed slots.

[0047] Preferably, two first bearings 240 are respectively installed in the holes inside the first support plate 210 and the third support plate 220, and two other first bearings 240 are respectively installed in the holes inside the insert rod 2101 and the fourth support plate 2201. The clamp 250 is fixedly installed on the first support plate 210 by bolts, and the two sets of housings 270 are fixedly installed on the back of the third support plate 220 by multiple bolts. The two coils 2702 pass through the connectors outside the two housings 270 and are connected to the power supply mechanism 400 by wires.

[0048] Among them, the inner side of the limiting wheel 2301 has a concave structure. The two adjacent limiting wheels 2301 can enhance the stability protection on both sides of the faulty cable 100, while ensuring the stability of the isolation mechanism when it travels outside the faulty cable 100.

[0049] In addition, the bottom cover 310 is fixedly installed on the first support plate 210 and the third support plate 220 by multiple bolts, while the front end of the folding cover 320 is fixedly installed on the insert rod 2101 and the fourth support plate 2201 by multiple bolts. When the folding cover 320 flips over, its pressure side contacts the bottom cover 310 and continues to be pressured, which can achieve rapid folding.

[0050] When the two drainage pads 340 are closed, they can pre-extinguish the fire extinguishing medium that has passed through the inner cavity of the bottom cover 310 and the folding cover 320 towards the front end of the faulty cable 100. After the fire is extinguished, the line segment of the faulty cable 100 passes through the inner cavity of the bottom cover 310 and the folding cover 320 and is circumferentially squeezed by the two solid pads 350, and the sharp protrusions on the surface of the faulty cable 100 can be quickly passivated.

[0051] Combination Figure 7 and Figure 8 As shown, based on the above embodiment, a sprayer 330 is fixedly installed in the middle of the bottom cover 310, a ring gasket 3101 is fixedly installed on the inner wall of the bottom cover 310, and a second bearing 360 is installed in the ring gasket 3101 and the groove of the inner wall of the bottom cover 310. A horizontally placed first linkage member 3601 is installed in the second bearing 360.

[0052] A driving component 370 and a second linkage component 380 are movably installed inside the base cover 310;

[0053] Multiple pressure relief slots are evenly distributed inside the arc-shaped shell at the bottom of the base cover 310;

[0054] The first linkage 3601 consists of a shaft and two deflecting gears, the driving member 370 consists of a shaft and a wide gear, and the second linkage 380 consists of a vertical shaft, a gear and a deflecting gear. The deflecting gear in the second linkage 380 meshes with one of the deflecting gears in the first linkage 3601, while the other deflecting gear in the first linkage 3601 meshes with the wide gear in the driving member 370.

[0055] Preferably, the pressure relief slot inside the bottom cover 310 can effectively guide and empty the excess extinguishing medium accumulated in the inner cavity of the bottom cover 310. At the same time, some of the overflowing extinguishing medium can also provide heat insulation and flame retardant protection for the bottom-mounted power supply mechanism 400 and the medium conveying mechanism 500.

[0056] Among them, the inner wall of the bottom cover 310 is provided with two cylindrical protrusions, and the inner shaft of the drive component 370 is inserted into the two cylindrical protrusions;

[0057] When the second linkage 380 is driven, the first linkage 3601, held by the second bearing 360, will assist the drive 370 in rotating. Finally, the set of pressure rollers 230 and the two limit rollers 2301 at the bottom can be effectively assisted, which makes it easy for the adaptive clamping mechanism 200 to move smoothly and effectively along the faulty cable 100, and further realizes the adaptive fire extinguishing treatment of different segments of the faulty cable 100 by the isolation mechanism.

[0058] Combination Figure 6 and Figure 9 As shown, based on the above embodiment, the power supply mechanism 400 includes an energy storage module 410 fixed to the bottom cover 310 by a nut, a housing 420 fixedly installed inside the energy storage module 410, a motor 460 fixedly installed inside the housing 420, a drive gear 470 installed on the motor 460, and the drive gear 470 meshes with the gear inside the second linkage 380.

[0059] The energy storage module 410 has wiring holes on both sides, and a horizontally placed sleeve 430 is installed outside the wiring holes. A photovoltaic module 440 is movably installed at the outer end of the sleeve 430, and a shield 450 is installed outside the photovoltaic module 440.

[0060] Preferably, the bottom of the cover 310 is provided with four threaded sections, and the top of the energy storage module 410 is provided with two pads. The two pads on the top of the energy storage module 410 are fixedly installed on the threaded sections by nuts. The wire on one side of the energy storage module 410 is adapted to connect with the wire outside the coil 2702, so as to facilitate real-time power supply to the two coils 2702.

[0061] Furthermore, the control panel inside the energy storage module 410 is controlled in real time by the client via wireless communication. In the initial state, the two photovoltaic modules 440 are distributed parallel to the fault cable 100, and the inner wall of the inner pipe section of the photovoltaic module 440 is provided with damping plates to facilitate the stability of the two photovoltaic modules 440 after the tilt angle of the two sleeves 430 is adjusted.

[0062] Combination Figure 2 and Figure 10 As shown, in the above embodiment, the medium conveying mechanism 500 includes a transfer pipe 5101 installed in the threaded port at the bottom of the sprayer 330. The bottom end of the transfer pipe 5101 is provided with an outer cylinder 510, and a cap 5102 is installed at the end of the outer cylinder 510. Two positioning members 530 are fixedly installed in the inner cavity of the outer cylinder 510. A horizontal shaft 540 is movably installed in the two positioning members 530. An impeller 550 is installed on the outside of the horizontal shaft 540, and an input pipe 520 is installed in the bottom pipe section of the outer cylinder 510.

[0063] One end of the horizontal shaft 540 is mounted on the shaft inside the motor 460.

[0064] Preferably, the inner wall of the outer cylinder 510 has a smooth coating structure, which helps to reduce the risk of fire extinguishing medium adhering or clumping. When the motor 460 is controlled and started by the client, the horizontal shaft 540 will drive the impeller 550 to rotate at high speed. The external storage tank connected through the input pipe 520 can continuously transfer the fire extinguishing medium into the inner cavity of the isolation fire extinguishing mechanism 300. The fire extinguishing medium sprayed outward by the isolation fire extinguishing mechanism 300 can effectively extinguish the burning section of the faulty cable 100. After the fire is extinguished, the section enters the isolation fire extinguishing mechanism 300 to store the fire extinguishing medium, which can be further cooled and solidified. Finally, the sharp protrusions on the surface of the faulty cable 100 that have not been completely cooled can be quickly passivated and smoothed by the two solid pads 350, which facilitates the safety of the subsequent recovery of the faulty cable 100 and reduces the risk to workers during the recovery of the faulty cable 100.

[0065] The working principle and usage process of this invention: In order to facilitate firefighting operations when outdoor cables are damaged by sudden failures, the user can use a pole-like tool or a flying device to lift or hoist the device to one side of the faulty cable 100.

[0066] Until the first tray 210 and the third tray 220 are located on both sides of the bottom of the faulty cable 100, when the plug 2101, the fourth tray 2201 and the folding cover 320 are flipped outward with the two second trays 2102 as the axis, the closed folding cover 320 and the bottom cover 310 can quickly clamp the faulty cable 100, and the closed two drainage pads 340 and two solid pads 350 can adapt and clamp the faulty cable 100.

[0067] In order to facilitate the control of the effectiveness and stability of the device's movement outside the faulty cable 100, the auxiliary traction rope 260 can be used to connect the rod section inside the clamp 250 until the exposed section of the auxiliary traction rope 260 is held and pulled by the worker.

[0068] Meanwhile, depending on the different heights at which the faulty cable 100 is installed, the bottom section of the outer cylinder 510 can be connected to the external tank for storing extinguishing medium through the input pipe 520 until the tank for storing extinguishing medium is fixed to the outer cylinder 510. The exposed end of the input pipe 520 can also be connected to the liquid injection equipment to extinguish the faulty cable 100 that has lost power and is burning, according to actual needs.

[0069] The operator can control the start and stop of the motor 460 through the client. In harsh environments such as high temperature, the two symmetrically distributed photovoltaic modules 440 can provide power to the energy storage module 410 at all times. When the motor 460 starts and runs, it will drive the drive gear 470 to rotate. The inner shaft of the motor 460 will drive the horizontal shaft 540 and the impeller 550 to rotate at high speed, which will facilitate the high-pressure input of the fire extinguishing medium from the transfer pipe 5101 and the sprinkler 330 to the inner cavity of the closed bottom cover 310 and the folding cover 320. The fire extinguishing medium will eventually be sprayed in the direction of travel of the device from the grooves on the inner wall of the two drainage pads 340. The two solid pads 350 can round off the sharp protrusions on the surface of the faulty cable 100 after cooling, reducing the safety hazards caused by the subsequent manual handling of the faulty cable 100.

[0070] After the drive gear 470 engages with the second linkage 380, the second linkage 380 will continuously assist the rotation of the first linkage 3601 and the drive member 370. The set of pressure rollers 230 and the two limit rollers 2301 assisted by the drive member 370 can rotate at a constant speed along the lower surface of the fault cable 100. In conjunction with the two sets of pressure rollers 230 and the limit rollers 2301, the fault cable 100 is clamped on both sides, thereby enabling the device to adaptively move laterally on the overhead fault cable 100.
