[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] Reference Figure 1-5 This utility model provides a distributed fault monitoring device for transmission lines, which includes: an upper housing 1 and a lower housing 2. A solar panel 3 is provided on the upper housing 1, and a solar panel cleaning component 4 is provided on the lower housing 2. The solar panel cleaning component 4 is provided with a quick-release component 5 and a cleaning panel replacement component 6. The solar panel cleaning assembly 4 includes a housing 45 and a cleaning arc plate 44. The housing 45 is fixedly installed on the outer wall of the lower housing 2. A forward and reverse motor 46 is fixedly installed on the outer wall of one end of the housing 45. The output shaft of the forward and reverse motor 46 passes through a through hole opened at one end of the housing 45. A threaded rod 47 is fixedly installed on the output shaft of the forward and reverse motor 46. The other end of the threaded rod 47 is rotatably installed on the inner wall of the other end of the housing 45. An internal threaded ring 48 is threadedly installed on the outer wall of the threaded rod 47. A drive rod 49 is fixedly installed on both sides of the internal threaded ring 48. A drive plate 42 is fixedly installed on the other end of the drive rod 49. A connecting arc plate 43 is fixedly installed on the top of the drive plate 42. Stroke grooves 41 are opened on both sides of the housing 45. The drive rod 49 is slidably installed on the inner wall of the stroke grooves 41.

[0020] In the distributed fault monitoring device for transmission lines described in this utility model, when the solar panel 3 needs to be cleaned, the forward and reverse motor 46, which is fixedly installed on the outer wall of one end of the housing 45, is started. Its output shaft drives the threaded rod 47 to rotate through the through hole at one end of the housing 45. The other end of the threaded rod 47 is rotatably installed on the inner wall of the other end of the housing 45 to ensure stable rotation. Since the threaded rod 47 has an internal threaded ring 48 threaded on its outer wall, the rotation of the threaded rod 47 is converted into linear movement of the internal threaded ring 48 along the axial direction of the threaded rod 47. At the same time, the drive rods 49 fixed on both sides of the internal threaded ring 48 move synchronously with the internal threaded ring 48, and the drive rods 49 slide in the travel grooves 41 opened on both sides of the housing 45. 41 acts as a guide and limiter for the drive rod 49, ensuring its smooth movement. The drive plate 42 connected to the other end of the drive rod 49 will move accordingly, thereby driving the connecting arc plate 43 fixed on the top of the drive plate 42 and the cleaning arc plate 44 connected to it to move synchronously. Since the forward and reverse motor 46 can achieve forward and reverse rotation, the threaded rod 47 will rotate accordingly in the forward and reverse directions, causing the internal threaded ring 48, drive rod 49 and drive plate 42 and other components to drive the cleaning arc plate 44 to reciprocate on the surface of the solar panel 3, thereby completing the cleaning operation of the solar panel 3. In addition, the quick-release component 5 and the cleaning plate replacement component 6 of the solar panel cleaning component 4 can help to realize the convenient disassembly and replacement of the cleaning components, ensuring the continuous effectiveness of the cleaning function.

[0021] The quick-release assembly 5 includes a plug 51, which is fixedly installed at both ends of the cleaning arc plate 44. Spring compartments 510 are provided on both sides of the plug 51. A second spring 511 is fixedly installed on the inner wall of the spring compartment 510. A pin 52 is fixedly installed on the other end of the second spring 511. The pin 52 is slidably connected to the inner wall of the spring compartment 510. A slot 53 is provided at one end of the connecting arc plate 43. Insertion holes 54 are provided on both sides of the slot 53. A push block 56 is slidably installed on the inner wall of the insertion hole 54. A first spring 57 is fixedly installed on the outer wall of the push block 56. The other end of the first spring 57 is fixedly installed on the inner wall of the insertion hole 54. Button compartments 55 are provided on both sides of one end of the connecting arc plate 43. A pressing block 59 is slidably installed on the inner wall of the button compartment 55. A connecting rod 58 is fixedly installed on the outer wall of the pressing block 59. The connecting rod 58 passes through a through hole in the inner wall of the button compartment 55. The other end of the connecting rod 58 is fixedly installed on the outer wall of the push block 56.

[0022] In the distributed fault monitoring device for transmission lines described in this utility model, when installing the cleaning arc plate 44, the plugs 51 fixed at both ends are aligned with the slots 53 opened at one end of the connecting arc plate 43 and inserted. Under the elastic force of the second spring 511, the pins 52 in the spring chambers 510 on both sides of the plug 51 slide outward along the inner wall of the spring chamber 510. When the plug 51 is fully inserted into the slot 53, the pins 52 just spring into the corresponding insertion holes 54 on both sides of the slot 53. The fixed connection between the cleaning arc plate 44 and the connecting arc plate 43 is achieved by the engagement of the pins 52 and the insertion holes 54. When it is necessary to disassemble the cleaning arc plate 44, the pressing blocks 59 in the button chambers 55 on both sides of one end of the connecting arc plate 43 are pressed. The pressing blocks 59 move along the button... As the inner wall of the key compartment 55 slides, the connecting rod 58 fixed on its outer wall moves synchronously through the through hole in the inner wall of the key compartment 55, thereby driving the push block 56 fixed at the other end of the connecting rod 58 to slide in the socket 54. When the push block 56 moves, it stretches the first spring 57. During the movement, the push block 56 pushes the pin 52 in the socket 54, pressing the pin 52 back into the spring compartment 510 of the plug 51 and compressing the second spring 511. At this time, the engagement between the pin 52 and the socket 54 is released, and the plug 51 can be pulled out from the slot 53, completing the quick disassembly of the cleaning arc plate 44. After releasing the pressing block 59, the elastic force of the first spring 57 will pull the push block 56 back to reset, and the connecting rod 58 will drive the pressing block 59 back to the initial position.

[0023] The cleaning plate replacement assembly 6 includes a base plate 61, with slots 63 at both ends of the base plate 61. A cleaning plate 62 is fixedly installed on one side of the base plate 61, and a second magnetic block 67 is fixedly installed on the other side of the base plate 61. An installation chamber 64 is provided on the outer wall of the cleaning arc plate 44, and a magnetic block groove 65 is provided on the inner wall of the installation chamber 64. A first magnetic block 66 is fixedly installed on the inner wall of the magnetic block groove 65.

[0024] In the distributed fault monitoring device for transmission lines described in this utility model, when installing the cleaning plate 62, the base plate 61 on which the cleaning plate 62 is fixed is aligned with the mounting chamber 64 opened on the outer wall of the cleaning arc plate 44. The second magnetic block 67 on the other side of the base plate 61 will attract the first magnetic block 66 fixed in the magnetic block groove 65 on the inner wall of the mounting chamber 64. Under the action of magnetic force, the base plate 61 is stably attracted in the mounting chamber 64, thereby making the cleaning plate 62 firmly installed on the cleaning arc plate 44 through the base plate 61, and completing the cleaning operation synchronously with the cleaning arc plate 44. When the cleaning plate 62 is installed... 2. When wear or aging occurs, the cleaning plate 62 needs to be replaced. By using the slots 63 at both ends of the base plate 61, the base plate 61 can be removed from the installation chamber 64 by applying force to the slots 63 to overcome the attraction between the first magnet 66 and the second magnet 67. Then, the new base plate 61 with the cleaning plate 62 is re-attached and fixed in the installation chamber 64 in the same way as described above, thus completing the quick replacement of the cleaning plate 62. The whole process does not require complicated tools. The cleaning plate 62 can be easily disassembled and replaced by magnetic attraction and the slots 63.

[0025] Working principle: When the forward and reverse motor 46 is started, its output shaft drives the threaded rod 47 to rotate. An internal threaded ring 48 is threaded onto the outer wall of the threaded rod 47. As the threaded rod 47 rotates, it drives the internal threaded ring 48 to move on its outer wall. Simultaneously, the displacement of the internal threaded ring 48 drives the drive plate 42 to move on both sides of the outer casing 45 via the drive rod 49. The drive rod 49 slides within the stroke groove 41. Simultaneously, the displacement of the drive plate 42 drives the connecting arc plate 43 to move on the outer wall of the lower casing 2. The connecting arc plate 43 simultaneously drives the cleaning arc plate 44 to move on the solar panel 3. The cleaning plate 62 on the cleaning arc plate 44 moves, thus cleaning the solar panel 3. When it is necessary to clean the solar panel assembly 4... During disassembly, simply press the pressing block 59. The pressing block 59, through the connecting rod 58, drives the push block 56 to move within the insertion hole 54. The push block 56 presses the pin 52, causing it to retract into the spring chamber 510. This allows the cleaning arc plate 44 to be pulled upwards, removing the insertion blocks 51 at both ends of the cleaning arc plate 44 from the slots 53. This separates the connecting arc plate 43 from the cleaning arc plate 44. When the cleaning plate 62 needs to be replaced, simply pry the base plate 61 out of the installation chamber 64 through the snap-fit ​​groove 63. At the same time, the second magnetic block 67 at the bottom of the base plate 61 separates from the first magnetic block 66 in the magnetic block groove 65, thus completing the disassembly of the cleaning plate 62. After taking out the new cleaning plate 62, the same process is used to complete the installation of the new cleaning plate 62.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
