Technical Field
[0001] This utility model belongs to the technical field of power extraction devices, specifically relating to a low-current power extraction device for power distribution lines. Background Technology
[0002] Current transformer power extraction technology extracts power from the magnetic field induced by the load current in the conductor. The power isolation transformation mainly relies on the principle of electromagnetic induction, which can perform both voltage transformation and current transformation. At present, all kinds of power transformation are mainly voltage transformation. From high-voltage power generation and transmission to low-voltage transformation inside electrical appliances, their basic structure is derived from voltage transformation mode.
[0003] In existing low-current power extraction devices for distribution networks, a current transmission tube and an electromagnetic inductor are fixedly connected to the outer wall of the protective shell of the extraction device. The current transmission tube and electromagnetic inductor are directly exposed, and debris from the external environment can easily fall onto the current transmission tube and electromagnetic inductor, causing damage and affecting their performance. The charge processor is fixed to the inner wall of the protective shell of the extraction device, making it difficult for operators to maintain or replace it. Utility Model Content
[0004] To address the problems mentioned in the background section, this utility model provides a low-current power extraction device for power distribution lines, featuring both mobile protection and fixed support.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-current power extraction device for a power distribution line, comprising a protective shell, a power extraction mechanism provided on the outer side wall of the protective shell, a protective shell door rotatably connected to one side of the protective shell, a charge processor provided inside the protective shell, a charge generating mechanism provided inside the protective shell and above the charge processor, a solar panel rotatably connected to the top of the protective shell, support components provided at both ends inside the protective shell and below the charge processor, and protective components provided on the side wall of the protective shell.
[0006] Preferably, the protective component includes a protective cover, an L-shaped sliding plate, through holes, a groove, and a fixing member. A groove is provided on the side wall of the protective cover, and an L-shaped sliding plate is slidably connected inside the groove. A fixing member is provided between the L-shaped sliding plate and the protective cover. The protective cover is fixedly connected to the end of the L-shaped sliding plate away from the protective cover. Through holes are provided on both sides of the protective cover.
[0007] Preferably, the fastener includes a perforation, an end plate, a threaded cylinder, and a threaded post. An end plate is fixedly connected to the side wall of the protective shell and below the slide groove. A perforation is provided on the end plate. A threaded post is fixedly connected to the lower part of the L-shaped slide plate. A threaded cylinder is threadedly connected to the outer side wall of the threaded post.
[0008] Preferably, strong magnetic blocks are fixedly connected to the sides of the L-shaped slide and the slide groove that are close to each other.
[0009] Preferably, the support assembly includes a fixing screw, a sliding nut, a sliding cylinder, and an L-shaped support plate. The fixing screw is fixedly connected to both ends inside the protective shell and below the charge processor. The sliding nut is threaded onto the outer wall of the fixing screw. The sliding cylinder is slidably connected to the periphery of the fixing screw and above the sliding nut. The L-shaped support plate is fixedly connected above the sliding cylinder.
[0010] Preferably, the fixed screw is fixedly connected to limit sliders on both sides of the end near the push cylinder, and a limit groove is formed on the inner side wall of the push cylinder at the position corresponding to the limit slider.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model is equipped with a protective component. The threaded cylinder is rotated off the threaded column and then the L-shaped slide plate is moved along the slide groove. The movement of the L-shaped slide plate causes the protective cover to move down, and the power grid wire moves and is engaged inside the through hole. The threaded column on the L-shaped slide plate moves through the through hole on the end plate, and then the threaded cylinder is rotated and screwed onto the threaded column. The threaded column and threaded cylinder can be used to fix the L-shaped slide plate and the end plate, thereby limiting and fixing the protective cover. The protective cover can protect the power taking mechanism, preventing debris from the external environment from falling onto the power taking mechanism, thereby preventing damage to the power taking mechanism and ensuring the normal use effect of the power taking mechanism.
[0012] 2. This utility model is equipped with a support component. The charge processor is placed inside the protective shell and made to fit against the bottom wall of the charge generating mechanism. Then, the push nut is rotated to make it rotate and move along the fixed screw. The rotation and movement of the push nut causes the push cylinder to move upward. The upward movement of the push cylinder causes the L-shaped support plate to move upward. When the L-shaped support plate moves and fits against the bottom wall of the charge processor, the rotation of the push nut is stopped. The L-shaped support plate can be used to support the charge processor, which facilitates the disassembly, assembly and maintenance of the charge processor. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Example 1 Please see Figure 1-4 The present invention provides the following technical solution: a low current power extraction device for a power distribution line, including a protective shell 2, a power extraction mechanism 7 is provided on the outer side wall of the protective shell 2, a protective shell door 4 is rotatably connected to one side of the protective shell 2, a charge processor 6 is provided inside the protective shell 2, a charge generating mechanism 3 is provided inside the protective shell 2 and above the charge processor 6, a solar panel 1 is rotatably connected to the top of the protective shell 2, support components 5 are provided at both ends inside the protective shell 2 and below the charge processor 6, and a protective component 8 is provided on the side wall of the protective shell 2.
[0017] Specifically, the protective component 8 includes a protective cover 81, an L-shaped sliding plate 82, a through hole 84, a groove 85, and a fixing member 86. A groove 85 is provided on the side wall of the protective shell 2. The L-shaped sliding plate 82 is slidably connected inside the groove 85. A fixing member 86 is provided between the L-shaped sliding plate 82 and the protective shell 2. The protective cover 81 is fixedly connected to the end of the L-shaped sliding plate 82 away from the protective shell 2. Through holes 84 are provided on both sides of the protective cover 81. By adopting the above technical solution, the L-shaped slide plate 82 moves along the slide groove 85. The movement of the L-shaped slide plate 82 causes the protective cover 81 to move down, and the power grid wire moves and is connected to the inside of the through hole 84. Then, the L-shaped slide plate 82 is fixed by the fixing part 86. The protective cover 81 can protect the power taking mechanism 7, prevent debris in the external environment from falling onto the power taking mechanism 7, thereby preventing damage to the power taking mechanism 7 and ensuring the normal use effect of the power taking mechanism 7.
[0018] Specifically, the fastener 86 includes a through hole 861, an end plate 862, a threaded cylinder 863, and a threaded post 864. The end plate 862 is fixedly connected to the side wall of the protective shell 2 and located below the slide groove 85. The end plate 862 has a through hole 861. The threaded post 864 is fixedly connected to the lower part of the L-shaped slide plate 82. The threaded cylinder 863 is threadedly connected to the outer side wall of the threaded post 864. By adopting the above technical solution, the threaded cylinder 863 is rotated off the threaded post 864, and then the L-shaped slide plate 82 is moved along the slide groove 85. When the L-shaped slide plate 82 moves to fit the inner bottom wall of the slide groove 85, the threaded post 864 on the L-shaped slide plate 82 moves to pass through the through hole 861 on the end plate 862. Then the threaded cylinder 863 is rotated and screwed onto the threaded post 864. The threaded post 864 and the threaded cylinder 863 can be used to fix the L-shaped slide plate 82 and the end plate 862, thereby limiting and fixing the protective cover 81, ensuring the stability of the protective cover 81, and thus ensuring the protective effect of the protective cover 81.
[0019] Specifically, strong magnetic blocks 83 are fixedly connected to the sides of the L-shaped slide plate 82 and the slide groove 85 that are close to each other. By adopting the above technical solution, when maintenance operations are required on the power extraction mechanism 7, the protective cover 81 is moved upward. The movement of the protective cover 81 causes the L-shaped sliding plate 82 to slide along the slide groove 85. When the strong magnetic block 83 on the L-shaped sliding plate 82 and the strong magnetic block 83 on the inner wall of the slide groove 85 attract and fix each other, the L-shaped sliding plate 82 can be limited and fixed, and thus the protective cover 81 can be limited and fixed, so as to avoid the protective cover 81 affecting the maintenance operations of the power extraction mechanism 7.
[0020] In this embodiment, the threaded cylinder 863 is rotated off the threaded post 864 and then the L-shaped slide plate 82 is moved along the slide groove 85. The movement of the L-shaped slide plate 82 causes the protective cover 81 to move downwards, and the power grid wire is moved and engaged inside the through hole 84. The threaded post 864 on the L-shaped slide plate 82 moves through the through hole 861 on the end plate 862. Then, the threaded cylinder 863 is rotated and screwed onto the threaded post 864. The threaded post 864 and the threaded cylinder 863 can be used to fix the L-shaped slide plate 82 and the end plate 862, thereby limiting and fixing the protective cover 81. The protective cover 81 can be used to protect the power taking mechanism 7 from external environmental factors. Debris falling into the power-collecting mechanism 7 can prevent damage to the power-collecting mechanism 7 and ensure its normal operation. When in use, on sunny days, the user uses the solar panel 1 to absorb solar energy and convert it into electrical energy. On cloudy days, the user uses the power-collecting mechanism 7 to obtain electrical energy from the power grid wire and transfer it into the device to ensure successful power collection. Then, the charge generating mechanism 3 generates positive and negative charges, and the charge processor 6 transfers the two charges into the internal part for processing to generate a small amount of electrical energy to maintain the device's operation. In case of damage to other power collection methods that require external force, the device can generate its own electricity to ensure normal operation. Example 2 The difference between this embodiment and Embodiment 1 is that the support assembly 5 includes a fixing screw 51, a sliding nut 52, a sliding cylinder 53, and an L-shaped support plate 54. Fixing screws 51 are fixedly connected to both ends of the protective shell 2, located below the charge processor 6. Sliding nuts 52 are threaded onto the outer walls of the fixing screws 51. Sliding cylinders 53 are slidably connected to the periphery of the fixing screws 51 and above the sliding nuts 52. An L-shaped support plate 54 is fixedly connected above the sliding cylinder 53. Specifically, the fixing screw 51 is fixedly connected to both sides of the end near the pushing cylinder 53, and a limiting slide groove is formed on the inner side wall of the pushing cylinder 53 at the position corresponding to the limiting slide. By adopting the above technical solution, the moving cylinder 53 moves and drives the limiting slider to move inside the limiting groove. When the limiting slider moves and fits against the side wall of the limiting groove, the limiting slider is blocked and stops moving, thereby preventing the moving cylinder 53 from continuing to move and avoiding the moving cylinder 53 from detaching from the fixing screw 51.
[0021] In this embodiment, the charge processor 6 is placed inside the protective shell 2 and made to fit against the bottom wall of the charge generating mechanism 3. Then, the push nut 52 is rotated to make it rotate and move along the fixing screw 51. The rotation and movement of the push nut 52 causes the push cylinder 53 to move upward, and the upward movement of the push cylinder 53 causes the L-shaped support plate 54 to move upward. After the L-shaped support plate 54 moves and fits against the bottom wall of the charge processor 6, the rotation of the push nut 52 is stopped. The L-shaped support plate 54 can be used to support the charge processor 6, which facilitates the disassembly and maintenance of the charge processor 6.
[0022] The structure and principle of the charge generating mechanism 3, which consists of a fixed track, movable wheels, and friction plates, have been disclosed in Chinese patent application No. 202020293598.9, which discloses a low-current power extraction device for a power distribution line. Its working principle is as follows: a fixed track is provided on the inner surfaces of both sides of the protective shell 2, movable wheels are provided on the outer surface of the fixed track, and friction plates are provided on the outer surface of the movable wheels. After the power extraction mechanism 7 successfully extracts power, the user uses the two friction plates to rub against each other by moving the movable wheels, so that one side carries a positive charge and the other side carries a negative charge. The charge processor 6 transfers the two charges to the inside for processing, generating a small amount of electrical energy.
[0023] The structure and principle of the power extraction mechanism 7, which consists of an electromagnetic inductor and a current transmission tube, in this utility model have been disclosed in a low-current power extraction device for a distribution network line disclosed in Chinese patent application number 202020293598.9. Its working principle is as follows: a current transmission tube is provided on the side of the protective shell 2, and an electromagnetic inductor is provided on the outer surface of the current transmission tube. The electromagnetic inductor is composed of two semi-circular current inductance sensors assembled into a circular current inductance sensor by a hoop. The electromagnetic inductor and the current transmission tube are fixedly connected. The user obtains electrical energy from the power grid conductor using the electromagnetic inductor, and transmits it into the device through the current transmission tube to ensure successful power extraction.
[0024] The working principle and usage process of this utility model are as follows: The threaded cylinder 863 is removed by rotating the threaded post 864. Then, the L-shaped sliding plate 82 moves along the slide groove 85. The movement of the L-shaped sliding plate 82 causes the protective cover 81 to move downwards, and the power grid wire moves and engages with the through hole 84. The threaded post 864 on the L-shaped sliding plate 82 moves through the through hole 861 on the end plate 862. The threaded cylinder 863 is then rotated and screwed onto the threaded post 864. The threaded post 864 and the threaded cylinder 863 can be used to fix the L-shaped sliding plate 82 and the end plate 862, thereby limiting and fixing the protective cover 81. The protective cover 81 can protect the power-generating mechanism 7, preventing debris from falling onto it and thus avoiding damage, ensuring the normal operation of the power-generating mechanism 7. The charge processor 6 is then placed inside the protective shell 2 and placed against the bottom wall of the charge-generating mechanism 3, and then rotated and pushed. Nut 52 rotates and moves along the fixed screw 51. The rotation of nut 52 drives the pusher cylinder 53 to move upward, which in turn drives the L-shaped support plate 54 to move upward. When the L-shaped support plate 54 moves and fits against the bottom wall of the charge processor 6, the rotation of nut 52 stops. The L-shaped support plate 54 can be used to support the charge processor 6, facilitating disassembly and maintenance. In use, on sunny days, the user uses the solar panel 1 to absorb solar energy and convert it into electrical energy. On cloudy days, the user uses the power extraction mechanism 7 to obtain electrical energy from the power grid and transfer it into the device to ensure successful power extraction. The charge generation mechanism 3 then generates positive and negative charges, and the charge processor 6 transfers the two charges into the device for processing to generate a small amount of electrical energy to maintain the device's operation. This prevents damage to the device when other devices require external power extraction. The device can generate its own electricity, ensuring normal operation.
