Description

Technical Field

[0001] The invention relates to the technical field of cable surface detection, in particular to a device for detecting surface faults of aerial power grid cables. Background Art

[0002] Aerial cables refer to power transmission cables installed overhead on electric poles, electric towers or other elevated structures. Such cables are usually fixed at high altitudes by brackets or insulators to cross terrain obstacles such as roads, railways, rivers, and oceans to transmit electric energy from power plants or substations to users or other power facilities in different locations. During the long-term use of aerial cables, short circuits, open circuits, and aging of the insulation layer may occur, resulting in power transmission interruptions, voltage fluctuations, current leakage, and power losses.

[0003] Generally, when inspecting the surface of cables at high altitudes, the inspection device is basically placed on the cable surface and then moved. Since there are often strong winds at high altitudes, the existing inspection devices generally have basically no protective measures.

When the device is blown by strong winds, it is easy to be blown away from the inspection area during inspection, resulting in deviations in the inspection, resulting in unstable inspection results and affecting the accuracy of the inspection.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, when strong winds occur during detection, the flat plate on the rotating toothed disc will be blown by the wind, thereby driving the rotating toothed disc and the fixed frame to rotate on the connecting disc. When the rotating toothed disc rotates, it will drive the gear shaft 2 to rotate. When the gear shaft 2 rotates, it will drive the sliding cylinder to move downward on the spring rod through the semicircular groove on the special-shaped plate. When the sliding cylinder moves downward, it will drive the stabilizing mechanism to move downward through the spring rod 2. When the spring rod 2 moves downward, the arc plate 2 will fit the surface of the cable. Then, when the pushing plate drives the spring rod 2 to continue to move downward, the spring rod 2 will squeeze the obtuse plate through the connecting plate. After the arc plate 2 is squeezed, the obtuse plate will rotate with the connection between the obtuse plate and the arc plate 2 as the center. When the obtuse plate rotates, the flexible belt at the bottom will fit the surface of the cable. At the same time, When the spring rod 2 moves downward, the movement of the spring rod 2 will push the piston plate to move downward at the opening of the arc plate 2. When the piston plate moves downward, it will squeeze the gas inside the opening of the arc plate 2. After being squeezed, the gas will enter the interior of the obtuse plate and expand the flexible bag. Since there are multiple arc plates 2, and after the arc plate 2 contacts the surface of the cable, under the movement of the spring rod 2, the arc plate 2 will cover the surface of the cable and squeeze the cable. After the cable is squeezed, the spring ball at the bottom of the arc plate 2 will shrink into the arc plate 2. When multiple arc plates 2 cover the cable, the shaking and displacement of the device in strong winds at high altitudes can be reduced, so that the device can still maintain its relative position on the cable and will not be blown away from the detection area by the wind, thereby ensuring the stability and accuracy of the detection work and avoiding detection deviations caused by wind.

[0019] 2. In the present invention, when the wind blows the rotating gear disc and makes it rotate, the rotating gear disc will rotate on the surface of the gear shaft through the fixed frame. When the fixed frame rotates, the friction force generated between the fixed frame and the gear shaft can drive the gear shaft to rotate. When the gear shaft rotates, it will drive the rotating plate meshing with it to rotate. When the rotating plate rotates, it will drive the hollow frame to rotate through the spring plate. When the hollow frame rotates, it will drive the flexible ball to rotate. In the process of the hollow frame rotating, the hollow frame will squeeze the arc plate. When the hollow frame squeezes the arc plate, the reaction force generated by the arc plate will push the hollow frame to drive the flexible ball to move downward, so that the flexible ball fits the surface of the cable and deforms. Then The flexible ball attached to the cable surface will rotate with the rotating plate through the hollow frame. When the flexible ball rotates with the rotating plate, the flexible ball will rotate on the surface of the cable. At this time, the deformation of the flexible ball will produce an extrusion force on the cable. This extrusion force can make the contact between the flexible ball and the cable surface closer. Then, when the flexible ball rotates, the friction force on the impurities on the cable surface will increase. Then, when the flexible ball rotates, the friction force will drive the impurities to move, thereby removing them from the cable surface, and timely cleaning the dust and impurities on the cable surface to ensure that the detection frame can accurately detect the true condition of the cable surface and reduce the possibility of misjudgment or missed detection due to dust coverage.

[0020] 3. In the present invention, when the rotation of the gear shaft drives the rotating plate to rotate, the rotating rotating plate will drive the hollow cylinder to rotate. When the hollow cylinder rotates, friction will be generated between the outer surface of the semicircular frame and the second rotating plate. Relying on the friction, when the hollow cylinder rotates with the rotating plate, the second rotating plate can be rotated. When the second rotating plate rotates, the diamond plate inside the hollow cylinder will be driven to continuously squeeze the second hollow cylinder. After being squeezed, the second hollow cylinder will move inside the hollow cylinder. When the second hollow cylinder moves, the crank rod will be pushed by the pushing plate to make it rotate. When the crank rod rotates, it will drive the fan at the bottom to rotate. The fan The wind force generated during rotation will enter the hollow frame through the hollow sleeve. At the same time, the movement of the hollow cylinder 2 will squeeze the gas between the hollow cylinder 2 and the hollow cylinder. The gas will also enter the hollow frame after being squeezed. Then, the gas inside the hollow frame will enter the flexible ball and be ejected through the circular holes on the flexible ball when the flexible ball rotates. The ejection of gas will form a certain airflow, which can directly impact the impurities on the surface of the cable and make them separate from the cable surface, which can further help clean the stubborn stains or fine particles on the cable surface and ensure the cleanliness of the cable surface, thereby improving the accuracy and reliability of detection.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When the obtuse angle plate 402 rotates, the bottom flexible belt The second arc plate 404 is fitted on the surface of the cable. At the same time, when the spring rod 306 moves downward, the movement of the second spring rod 306 will push the piston plate 403 to move downward at the opening of the second arc plate 404. When the piston plate 403 moves downward, the gas inside the opening of the second arc plate 404 will be squeezed. After being squeezed, the gas will enter the interior of the obtuse plate 402 and expand the flexible bag. Since there are multiple second arc plates 404, and after the second arc plate 404 contacts the surface of the cable, under the movement of the second spring rod 306, the second arc plate 404 will cover the surface of the cable and squeeze the cable. After the cable is squeezed, the spring ball at the bottom of the second arc plate 404 will shrink into the second arc plate 404. When multiple second arc plates 404 cover the cable, the shaking and displacement of the device in high-altitude strong winds can be reduced, so that the device can still maintain its relative position on the cable and will not be blown away from the detection area by the wind, thereby ensuring the stability and accuracy of the detection work and avoiding detection deviations caused by wind.

[0048] When the wind blows the rotating gear disc 202 and makes it rotate, the rotating rotating gear disc 202 will rotate on the surface of the gear shaft 105 through the fixing frame 203. When the fixing frame 203 rotates, the friction force generated between the fixing frame 203 and the gear shaft 105 can drive the gear shaft 105 to rotate. When the gear shaft 105 rotates, it will drive the rotating plate 501 meshed therewith to rotate. When the rotating plate 501 rotates, it will drive the hollow frame 504 to rotate through the spring plate 503. When the hollow frame 504 rotates, it will drive the flexible ball 505 to rotate. In the process of the rotation of the hollow frame 504, the hollow frame 504 will squeeze the arc plate 106. When the hollow frame 504 squeezes the arc plate 106, the reaction force generated by the arc plate 106 will push the hollow frame 504 to drive the flexible ball 505 to move downward, so that the flexible ball 50 5 is attached to the surface of the cable and deformed, and then the flexible ball 505 attached to the surface of the cable will rotate with the rotating plate 501 through the hollow frame 504. When the flexible ball 505 rotates with the rotating plate 501, the flexible ball 505 will rotate on the surface of the cable. At this time, the deformation of the flexible ball 505 will generate an extrusion force on the cable, and this extrusion force can make the contact between the flexible ball 505 and the cable surface closer. Then, when the flexible ball 505 rotates, the friction force on the impurities on the cable surface will increase. Then, when the flexible ball 505 rotates, the friction force will drive the impurities to move, thereby removing them from the cable surface, and timely cleaning the dust and impurities on the cable surface, ensuring that the detection frame 102 can accurately detect the real condition of the cable surface, and reducing the possibility of misjudgment or missed detection due to dust coverage.

[0049] When the rotation of the gear shaft 105 drives the rotating plate 501 to rotate, the rotating rotating plate 501 will drive the hollow cylinder 601 to rotate. When the hollow cylinder 601 rotates, friction will be generated between the outer surface of the semicircular frame 104 and the rotating plate 2 602. Relying on the friction, when the hollow cylinder 601 rotates along with the rotating plate 501, the rotating plate 2 602 can be rotated. When the rotating plate 2 602 rotates, the diamond plate inside the hollow cylinder 601 will be driven to continuously squeeze the hollow cylinder 2 603. After being squeezed, the hollow cylinder 2 603 will move inside the hollow cylinder 601. When the hollow cylinder 2 603 moves, it will push the crank rod 605 through the pushing plate 604 to make it rotate. When the crank rod 605 rotates, it will drive the bottom The fan rotates, and the wind force generated by the rotation of the fan will enter the hollow frame 504 through the hollow sleeve 606. At the same time, the movement of the hollow cylinder 603 will also squeeze the gas between the hollow cylinder 603 and the hollow cylinder 601. After being squeezed, the gas will also enter the hollow frame 504. Then, the gas inside the hollow frame 504 will enter the flexible ball 505 and be ejected through the circular hole on the flexible ball 505 when the flexible ball 505 rotates. The ejection of gas will form a certain airflow, which can directly impact the impurities on the cable surface and make them separate from the cable surface, which can further help clean the stubborn stains or fine particles on the cable surface, ensure the cleanliness of the cable surface, and thus improve the accuracy and reliability of detection.
