With the continuous expansion of the scale of power grids and the continuous advancement of technology, the requirements for transmission line fault diagnosis technology are becoming higher and higher. As an important part of the power grid monitoring system, the accuracy and timeliness of distributed fault monitoring devices are of great significance for quickly locating faults, shortening power outages, and improving power supply reliability.

[0003] Distributed fault monitoring devices can quickly collect and transmit fault information by deploying multiple monitoring points at key nodes of the transmission line.

[0004] Problems with existing technologies: The current distributed fault monitoring devices mainly rely on photovoltaic panels as the only source of charging and power supply. This single power supply mode will cause the equipment to not operate normally in an environment with insufficient light, such as cloudy days, thus significantly weakening its use efficiency. In addition, photovoltaic panels are also susceptible to the impact of birds staying: on the one hand, the shading of birds will reduce the effective light received by the photovoltaic panels and reduce the photoelectric conversion efficiency; on the other hand, the long-term stay of birds may also leave pollutants such as feces, which are not only difficult to clean, but also have a long-term negative impact on the performance of photovoltaic panels, further reducing the overall operation effect of the equipment.

[0026] According to the above structure, when a bird falls on the photovoltaic panel 6, the photovoltaic panel 6 sinks due to the increase in weight, and pushes the square plug 5 downward, and then drives the first gear 13 to rotate through the first toothed plate 14, and the first gear 13 drives the first shaft 12 to rotate, and the first shaft 12 drives the second shaft 20 to rotate through the bevel gear set 18, and the second shaft 20 drives the driving rod 21 to rotate above the photovoltaic panel 6, so as to drive away the bird falling on the photovoltaic panel 6, and at the same time, the rotation of the first shaft 12 drives the second gear 15 to rotate, and the second gear 15 and the arc-shaped toothed plate 16 is engaged, driving the arc-shaped mounting plate 9 to rotate to one side, and the arc-shaped mounting plate 9 drives the photovoltaic panel 6 to rotate to one side through the first guide rod 10, so that the bird cannot stand steadily on the photovoltaic panel 6, and it is not easy to stay on the photovoltaic panel 6, so as to avoid affecting the power generation effect of the photovoltaic panel 6; the first spring 11 is set, and when the bird flies away from the photovoltaic panel 6, the photovoltaic panel 6 is reset through the elastic force of the first spring 11; the setting of the arc-shaped slide groove 7 and the square plug rod 5 makes the photovoltaic panel 6 rotate smoothly to one side during the downward movement process, thereby improving the stability of the movement of the photovoltaic panel 6.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a wind power generation assembly is arranged below the lower box body 1, and the wind power generation assembly includes a mounting cylinder 35, and a tail wing plate 36 for automatically tracking the wind direction is arranged on the outer wall of the end of the mounting cylinder 35, and a generator 37 is arranged inside the other end of the mounting cylinder 35, and the output shaft of the generator 37 is provided with a first wind blade 42 for rotating to one side according to the wind force and gathering to reduce wind resistance; The output shaft of the generator 37 is fixed with a mounting head 39, and a plurality of fixing ears 40 are fixed on the outer surface of the mounting head 39 along the circumferential direction. A third mounting block 41 is rotatably mounted between the outer walls of the two fixing ears 40, and a first fan blade 42 is fixed to the outer wall of the third mounting block 41. A second connecting rod 43 is hinged on one side of the first fan blade 42, and a second guide rod 44 is rotatably mounted on the other end of the second connecting rod 43. A rotating ring 45 is sleeved on the outer wall of the mounting cylinder 35, and a bearing 49 is arranged at the rotating connection between the rotating ring 45 and the mounting cylinder 35. A plug hole 47 connected to the second guide rod 44 for damping sliding is opened on one side of the rotating ring 45, and a third spring 48 connected to one end of the second guide rod 44 is fixed on the inner side of the plug hole 47. A plurality of second fan blades 46 for reducing the rotation resistance of the first fan blade 42 are arranged on the outer wall of the rotating ring 45 along the circumferential direction. The size of the first fan blade 42 is three times the size of the second fan blade 46. A conical cover 38 for protecting the generator 37 is arranged at the end of the mounting cylinder 35. Rain shielding strips 23 for blocking rainwater are arranged on both sides of the lower box body 1 . The rain shielding strips 23 prevent rainwater from falling onto the mounting tube 35 along the curved surface of the lower box body 1 , and prevent rainwater from penetrating into the generator 37 in the mounting tube 35 .

[0028] According to the above structure, the cooperation between the generator 37 and the first fan blade 42 can utilize external wind power to generate electricity and charge the battery 50; when the wind force is relatively strong, the external wind blows the first fan blade 42 to rotate on one side, so that multiple first fan blades 42 rotate and gather toward one side, reducing the windward area of ​​the first fan blade 42, thereby reducing wind resistance. In the case of strong winds, the first fan blade 42 can be effectively protected, and its service life and stability of use can be improved. The first fan blade 42 drives the second guide rod 44 to slide in the plug hole 47 through the second connecting rod 43, and the third spring 48 can also effectively buffer the first fan blade 42, further protecting the first fan blade 42. When the wind force is relatively small, the elastic force of the third spring 48 pushes the second guide rod 44 to slide in the plug hole 47. 44 is reset, thereby resetting and unfolding the plurality of first fan blades 42, so that the first fan blades 42 can continue to be used and generate electricity; the rotating ring 45 is rotatably connected to the mounting tube 35 through the bearing 49, which can effectively reduce the friction of its rotation, so that the first fan blade 42 is relatively smooth, and the second fan blade 46 is set, and the wind energy drives the second fan blade 46 to rotate, and drives the rotating ring 45 to rotate, so as to avoid affecting the normal rotation of the first fan blade 42, further improving the smoothness of the rotation of the first fan blade 42, and also improving the effect of wind power generation; the tail wing plate 36 is set, such as the tail wing of the weather vane in the prior art, which can automatically rotate the mounting tube 35 according to the wind direction, and make the first fan blade 42 always face the direction of the wind, so that the wind energy blows the first fan blade 42 to rotate.

[0029] like Figure 1 and Figure 7As shown, a buffer mechanism for multi-directional shock absorption of the wind power generation component is provided at the bottom of the lower box body 1, through two mutually docking annular arc rubbers 29 provided between the second mounting block 25 and the first mounting block 24, and the arc rubber 29 absorbs and disperses impacts and vibrations from multiple directions; the buffer mechanism includes a first mounting block 24 fixed to the bottom of the lower box body 1, a second mounting block 25 is provided below the first mounting block 24, and ball grooves 26 are provided on the opposite surfaces of the second mounting block 25 and the first mounting block 24, and a ball block 27 is provided inside the ball groove 26, a first connecting rod 28 is fixed between the two ball blocks 27, and the second mounting block 25 is provided on the opposite surfaces of the first mounting block 24. A connecting shaft 34 that is bolted to the mounting tube 35 is rotatably mounted at the bottom of the block 25; two circular arc rubbers 29 that are butt-jointed to each other are arranged between the second mounting block 25 and the first mounting block 24. The arc rubber 29 is made of EPDM rubber, has good elasticity and wear resistance, and can deform and absorb energy when subjected to external force. An arc groove 30 is arranged inside the arc rubber 29, and an arc plate 31 is fixed to the inner top and inner bottom of the arc groove 30. A plurality of second springs 32 are arranged between the outer walls of the two arc plates 31, and connecting ears 33 extending to the outside of the arc rubber 29 are fixed at both ends of the arc plate 31.

[0030] According to the above structure, when the wind power generation component is impacted by strong wind and vibrates, the arc rubber 29 is deformed to absorb and disperse the impact energy, and the arc plate 31 and the second spring 32 further enhance the shock absorption effect through their elasticity and support. The arc plate 31 is provided to provide a stable support structure for the arc rubber 29, while allowing it to deform when subjected to external force. A plurality of second springs 32 are arranged between the arc plates 31 to provide additional elastic support for the buffer mechanism. The design of the ball groove 26 and the ball block 27 allows a certain relative movement ability between the first mounting block 24 and the second mounting block 25, so that the arc rubber 29 can absorb and disperse the impact and vibration in multiple directions to a certain extent, reduce the influence of vibration on the lower box body 1, and thus improve the accuracy of the equipment in monitoring the transmission line.

[0031] The working principle of the present invention is as follows: the photovoltaic panel 6 can convert sunlight into electrical energy to charge the battery 50; when a bird falls on the photovoltaic panel 6, the photovoltaic panel 6 moves downward, pushing the square plug 5 to move downward, and then the first gear 13 is driven to rotate through the first toothed plate 14, the first gear 13 drives the first rotating shaft 12 to rotate, the first rotating shaft 12 drives the second rotating shaft 20 to rotate through the bevel gear set 18, and the second rotating shaft 20 drives the driving rod 21 to rotate above the photovoltaic panel 6, so as to drive away the bird falling on the photovoltaic panel 6, and at the same time, the rotation of the first rotating shaft 12 drives the second gear 15 to rotate, the second gear 15 is meshed with the arc-shaped toothed plate 16, and drives the arc-shaped mounting plate 9 to rotate to one side, and the arc-shaped mounting plate 9 drives the photovoltaic panel 6 to rotate to one side through the first guide rod 10, so that the bird cannot stand steadily on the photovoltaic panel 6, and it is not easy to stay on the photovoltaic panel 6, so as to avoid affecting the power generation effect of the photovoltaic panel 6; Providing the tail wing plate 36 can ensure that the first wind blade 42 is always aligned with the wind direction, thereby effectively utilizing the external wind force to drive the first wind blade 42 to rotate. The first wind blade 42 and the generator 37 work together to realize the conversion of wind energy into electrical energy and provide charging support for the battery 50. When encountering strong winds, the first wind blade 42 will automatically adjust with the wind direction and gather to the leeward side, effectively reducing the windward area and reducing wind resistance. This design not only enhances the wind resistance of the first wind blade 42, but also significantly improves its service life and stability. At the same time, the first fan blade 42 drives the second guide rod 44 to slide in the plug-in hole 47 with damping through the second connecting rod 43. Combined with the buffering effect of the third spring 48, additional protection is provided for the first fan blade 42. When the wind weakens, the elastic force of the third spring 48 prompts the second guide rod 44 to reset, driving the first fan blade 42 to re-expand, ensuring continuous power generation. In addition, the rotating ring 45 is flexibly rotatably connected to the mounting cylinder 35 through the bearing 49, which effectively reduces the friction during the rotation process, making the rotation of the first fan blade 42 smoother. The additional second fan blade 46 rotates independently under the action of wind force and drives the rotating ring 45 to rotate. This design avoids mutual interference with the first fan blade 42, further improving the rotation efficiency of the first fan blade 42 and the overall effect of wind power generation.

[0032] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
