Description

Technical Field

[0001] The present invention mainly relates to the technical field of power grid fault indication, and particularly relates to a fault indicator and a fault detection method thereof. Background Art

[0002] A distribution line fault indicator is a fault information indicating device used to detect and indicate whether the fault loop of the user's power line flows through here. Its working principle is that when a fault occurs in the power line, due to the sudden change of electrical parameters in the line, changes in the magnetic field and electric field are generated around the power line. The control circuit inside the power line fault indicator monitors these changes, automatically judges whether the fault loop flows through here, and then outputs an alarm signal to drive the display part to work, and alarms and flashes a red indicator light, so as to achieve the purpose of indicating the fault of the fault line;

[0003] However, the lamp tubes of the current fault indicators are exposed for a long time, which easily reduces the service life of the lamp tubes, thereby increasing the use cost, making it difficult to detect in time after the lamp tubes are damaged, and making it difficult to play an indicating role. Therefore, the present invention provides a fault indicator and a fault detection method thereof to solve the above problems. Summary of the Invention

[0008] Further, the fixing mechanism includes a fixing block connected to the top of the protective cover, a buffer assembly connected to the groove body at the top of the fixing block, and a pressing block slidably connected to the top of the fixing block.

[0009] Further, the buffer assembly includes second telescopic members connected to both sides of the top groove of the fixed block, second springs sleeved on the second telescopic members, and buffer blocks connected to the tops of the second telescopic members. The buffer blocks and the pressing blocks are both provided with arc-shaped grooves, and the groove bodies of the arc-shaped grooves are provided with a plurality of rubber protrusions.

[0010] Further, the limiting mechanism includes sleeves connected to both sides of the fixed block, limiting rods slidably connected to the inner walls of the sleeves, and third springs sleeved on one side of the limiting rods. The two limiting rods are connected by a pull plate.

[0011] Further, one side of the bottom of the pressing block is fixed with an insertion plate, the insertion plate is slidably connected to a slot provided in the fixed block, and limiting grooves are provided on both sides of the insertion plate. The groove bodies of the limiting grooves cooperate with the limiting rods.

[0013] One side of the top of the limiting rod is provided with a second bevel edge, and the second bevel edge cooperates with the first bevel edge.

[0014] Further, a solar panel is connected to the top of the pressing block. The solar panel is electrically connected to a storage battery, and the storage battery is located inside the pressing block.

[0015] Further, a plurality of rollers are rotatably connected to one side of the arc-shaped plate;

[0016] A plurality of square holes are provided at the bottom of the protective cover, and the hole bodies of the square holes cooperate with the arc-shaped plate.

[0017] Further, a limiting chute is provided on one side of the inner wall of the protective cover;

[0018] A limiting plate is fixed to one side of the moving block, and the limiting plate is slidably connected to the groove body of the limiting chute.

[0019] According to the above technical solution of a fault indicator, a fault detection method for a fault indicator will also be provided, including the following steps:

[0020] S1. Detect whether an induced magnetic field is generated through the induction disk. If it is generated, the induction disk will rotate, thereby causing the threaded rod to rotate;

[0021] S2. Rotate the threaded rod to raise and lower the moving block, so that the contact piece contacts the C-shaped contact piece, and then current passes through the indicator light to make the indicator light emit light. At the same time, drive the indicator light to rotate through the threaded rod, and make the indicator light pop out of the protective cover through the first spring.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] In the present invention, by pressing the lower pressing block, the insertion plate squeezes the limiting rod, so that the limiting rod contracts. During the descending process of the lower pressing block, the elastic force of the third spring causes the limiting rod to enter the limiting groove, thereby restricting the position of the lower pressing block. Thus, the lower pressing block and the buffer block fix the cable. When a momentary current is generated due to a power outage or short circuit in the cable, an induced magnetic field will be generated, which will push the induction disk to rotate, drive the threaded rod to rotate, drive the moving block and the contact piece to move up and down, and then make the contact piece contact the C-shaped contact piece to achieve conduction, allowing the current to enter the indicator light, so that the indicator light emits light. At the same time, the threaded rod drives the indicator light to rotate. When the arc-shaped plate rotates to the square hole, the elastic force of the first spring causes the indicator light to pop out of the outside of the protective cover, facilitating the observation of the indicator light. This device can not only clamp the cable, stably fix the device on the cable, facilitate the installation and disassembly of the device, but also protect the indicator light, prevent the reduction of the service life of the indicator light caused by the indicator light being outside the protective cover, and can automatically pop out the indicator light according to the fault.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0035] Embodiment, please refer to the attached Figures 1-5 , A fault indicator, comprising a protective cover 10, a fixing mechanism 20 is connected to the top of the protective cover 10, a limiting mechanism 30 is connected to one side of the top of the fixing mechanism 20, a storage battery 70 is connected to the top of the fixing mechanism 20, a C-shaped contact 40 is connected to the bottom of the fixing mechanism 20, and the C-shaped contact 40 is connected to the storage battery 70 through an electric wire;

[0036] The bottom of the fixing mechanism 20 is connected to a detection and indication device 50. The detection and indication device 50 includes a threaded rod 51 rotatably connected to the bottom of the fixing mechanism 20, an induction disk 52 connected to the top of the threaded rod 51, a moving block 53 penetrating and connected to the top of the threaded rod 51, and a contact piece 54 connected to one side of the moving block 53. The contact piece 54 cooperates with the C-shaped contact 40;

[0037] A plurality of sides of the bottom of the threaded rod 51 are connected to a first telescopic member 55. A first spring 56 is sleeved on the outer wall of the first telescopic member 55. One side of the first telescopic member 55 is connected to an indicator light 57. One side of the indicator light 57 is connected to an arc-shaped plate 58.

[0038] It should be noted that in this embodiment, the contact piece 54 is connected to the indicator light 57 through an electric wire. When the cable is powered off or a short-circuit instantaneous current occurs, an induced magnetic field will be generated, thereby driving the induction disk 52 to rotate. The implementation principle of this process is the existing electromagnetic induction principle. The induction disk 52 drives the threaded rod 51 to rotate, thereby driving the moving block 53 and the contact piece 54 to move up and down, and further enabling the contact piece 54 to contact the C-shaped contact piece 40 to achieve conduction, allowing current to enter the indicator light 57 and making the indicator light 57 emit light. The threaded rod 51 drives the indicator light 57 to rotate, so that the indicator light 57 pops out of the outside of the protective cover 10 through the elastic force of the first spring 56, facilitating the observation of the indicator light 57;

[0039] Furthermore, a rotating handle is fixed at the bottom of the threaded rod 51, which is convenient for the staff to manually rotate the threaded rod 51 to reset the contact piece 54.

[0040] For the embodiment, please refer to the attached Figure 2 , the fixing mechanism 20 includes a fixing block 21 connected to the top of the protective cover 10, a buffer assembly 23 connected to the groove body at the top of the fixing block 21, and a pressing block 22 slidably connected to the top of the fixing block 21.

[0042] For the embodiment, please refer to the attached Figures 2-3 , the buffer assembly 23 includes second telescopic members 231 connected to both sides of the groove body at the top of the fixing block 21, second springs 232 sleeved on the second telescopic members 231, and a buffer block 233 connected to the top of the second telescopic members 231. The buffer block 233 and the pressing block 22 are both provided with arc-shaped grooves, and a plurality of rubber convex bodies are provided on the groove body of the arc-shaped groove.

[0043] It should be noted that in this embodiment, the elastic force of the second spring 232 enables the buffer block 233 to have a buffer space and can reset the buffer block 233, thereby facilitating the ejection of the buffer block 233 and enabling the pressing block 22 to rise, so as to disengage from the limiting mechanism 30, avoiding the need for manual movement of the pressing block 22 to disengage it from the limiting mechanism 30. The rubber convex bodies facilitate increasing the friction between the cable and the buffer block 233 and the pressing block 22.

[0044] For the embodiment, please refer to the attached Figure 4 , the limiting mechanism 30 includes sleeves 31 connected to both sides of the fixing block 21, limiting rods 33 slidably connected to the inner walls of the sleeves 31, and third springs 32 sleeved on one side of the limiting rods 33. The two limiting rods 33 are connected by a pull plate.

[0045] It should be noted that in this embodiment, the elastic force of the third spring 32 is used to reset the limit rod 33, thereby restricting the position of the pressing block 22. The pulling plate facilitates the staff to pull the limit rod 33, so that the limit of the pressing block 22 by the limit rod 33 is cancelled, facilitating the removal of the device.

[0046] For the embodiment, please refer to the attached Figure 2 , one side of the bottom of the pressing block 22 is fixed with an insertion plate 221. The insertion plate 221 is slidably connected to a slot provided in the fixed block 21. Limiting grooves 2212 are provided on both sides of the insertion plate 221, and the groove bodies of the limiting grooves 2212 cooperate with the limit rod 33.

[0047] It should be noted that in this embodiment, the cooperation between the limiting groove 2212 and the limit rod 33 facilitates restricting the position of the insertion plate 221, thereby restricting the position of the pressing block 22 and realizing the fixation of the device.

[0048] For the embodiment, please refer to the attached Figure 4 , one side of the bottom of the insertion plate 221 is provided with a first bevel edge 2211;

[0049] One side of the top of the limit rod 33 is provided with a second bevel edge 331, and the second bevel edge 331 cooperates with the first bevel edge 2211.

[0050] It should be noted that in this embodiment, the cooperation between the second bevel edge 331 and the first bevel edge 2211 facilitates the insertion plate 221 to press the limit rod 33, so that the limit rod 33 contracts.

[0051] For the embodiment, please refer to the attached Figure 2 , the top of the pressing block 22 is connected to a solar panel 60. The solar panel 60 is electrically connected to a storage battery 70, and the storage battery 70 is located inside the pressing block 22.

[0052] It should be noted that in this embodiment, the solar panel 60 facilitates absorbing solar energy and converting it into electrical energy for storage in the storage battery 70, and can provide energy for the indicator light 57.

[0053] For the embodiment, please refer to the attached Figure 3 and Figure 5 , a plurality of rollers 581 are rotatably connected to one side of the arc-shaped plate 58;

[0054] A plurality of square holes 11 are provided at the bottom of the protective cover 10, and the hole bodies of the square holes 11 cooperate with the arc-shaped plate 58.

[0055] It should be noted that in this embodiment, the square hole 11 facilitates the passage of the arc-shaped plate 58 through the protective cover 10, enabling the indicator light 57 to move to the outside of the protective cover 10. The roller 581 reduces the friction between the arc-shaped plate 58 and the protective cover 10, facilitating the movement of the arc-shaped plate 58.

[0056] For the embodiment, please refer to the attached Figure 3 , on one side of the inner wall of the protective cover 10, there is a limit sliding groove 12;

[0057] On one side of the moving block 53, a limit plate 531 is fixed, and the limit plate 531 is slidably connected to the groove body of the limit sliding groove 12.

[0058] It should be noted that in this embodiment, the cooperation between the limit sliding groove 12 and the limit plate 531 restricts the rotation of the moving block 53, preventing the moving block 53 from rotating with the threaded rod 51.

[0059] For the embodiment, please refer to the attached Figure 6 , according to the technical solution of a fault indicator above, a fault detection method for the fault indicator will also be provided, including the following steps:

[0060] S1. Detect whether an induced magnetic field is generated through the induction disk 52. If it is generated, the induction disk 52 will rotate, thereby causing the threaded rod 51 to rotate;

[0061] S2. Rotate the threaded rod 51 to lift and lower the moving block 53, so that the contact piece 54 contacts the C-shaped contact piece 40, and then current passes through the indicator light 57 to make the indicator light 57 emit light. At the same time, drive the indicator light 57 to rotate through the threaded rod 51, so that the indicator light 57 pops out of the protective cover 10 through the first spring 56.

[0062] The specific operation method of the present invention is as follows: By pressing the lower pressing block 22, the insertion plate 221 squeezes the limit rod 33, so that the limit rod 33 contracts. During the descent of the lower pressing block 22, the limit rod 33 enters the limit groove 2212 through the elastic force of the third spring 32, thereby restricting the position of the lower pressing block 22, and thus fixing the cable by the lower pressing block 22 and the buffer block 233;

[0063] When a momentary current is generated due to power failure or short circuit of the cable, an induced magnetic field will be generated, thereby pushing the induction disk 52 to rotate, driving the threaded rod 51 to rotate, driving the moving block 53 and the contact piece 54 to lift and lower, and then making the contact piece 54 contact the C-shaped contact piece 40 to achieve conduction, enabling current to enter the indicator light 57, so that the indicator light 57 emits light. At the same time, drive the indicator light 57 to rotate through the threaded rod 51. When the arc-shaped plate 58 rotates to the square hole 11, the indicator light 57 pops out of the outside of the protective cover 10 through the elastic force of the first spring 56, facilitating the observation of the indicator light 57.

[0064] The present invention has been described by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned methods. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
