Description
Technical Field
[0001] The invention relates to the technical field of overhead cable equipment inspection, in particular to an overhead high-voltage cable live inspection device based on infrared thermal imaging. Background Art
[0002] In the power industry, the inspection of overhead high-voltage cables and their supporting structures (such as crossarms and hardware) is an important part of ensuring the safe operation of the power grid. However, the traditional inspection method has many shortcomings, which are specifically manifested in the following aspects:
[0003] First, traditional inspection methods are highly dependent on manual labor, especially for the inspection of high-altitude equipment, such as the crossarms and hardware that directly support high-voltage cables, which often require inspectors to climb poles or use aerial work vehicles to perform high-altitude operations. This operation method is not only labor-intensive, but also requires high physical strength and skills of inspectors, and there are also high safety risks, such as falling from heights and electric shock.
[0004] Secondly, traditional inspection methods usually need to be carried out in a power outage state to ensure the safety of inspectors. However, power outage operations not only affect the normal power consumption of users, but may also have an adverse impact on the stable operation of the power grid, such as causing voltage fluctuations, load transfer and other problems. At the same time, power outage operations require the arrangement of special power outage plans and coordination with users, dispatching departments and other parties, which increases the workload and complexity.
[0005] Furthermore, the traditional inspection method is inefficient. Inspectors need to check each device one by one, record its status, and record any damage or abnormality found in the cables and their supporting equipment. This process is time-consuming and prone to missed inspections or misjudgments. In addition, the inspection results need to be manually compiled into a report, and then notified to the maintenance personnel for follow-up processing. The entire process is cumbersome and time-consuming.
[0006] Finally, for the damaged parts found, the traditional way is often to transmit information through paper records or verbal notifications. This method is not only prone to errors, but may also cause maintenance delays due to untimely information transmission. Especially for the damage of key components, the delay time will greatly increase the maintenance cost and cable operation risk.
[0007] In summary, the traditional overhead cable inspection method has problems such as high consumption of manpower and material resources, low efficiency, high safety risks, cumbersome processes and poor information transmission. To this end, we propose an overhead high-voltage cable live inspection device based on infrared thermal imaging. Summary of the invention

DETAILED DESCRIPTION
[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0040] Embodiment 1:
[0041] See also Figure 1-9 The present invention provides a technical solution: an overhead high-voltage cable live inspection device based on infrared thermal imaging, comprising a control terminal 1 and a clamping frame 10, a mechanical arm 2 is fixed on the control terminal 1, the mechanical arm 2 is a prior art, the clamping frame 10 is composed of two semicircular frames 11, one end of the semicircular frame 11 on one side is equipped with a hinge 12, the hinge 12 is connected to one end of the other semicircular frame 11, and the hinge 12 connects the two semicircular frames 11, and also includes:
[0042] A high-definition camera 20 is installed on the robot arm 2 and is electrically connected to the control terminal 1. An exposure component is provided inside the high-definition camera 20, and a photosensitive component 21 is installed on the top. A text recognition system, a color difference comparison system, an infrared thermal imaging system, and a photo map line break and missing recognition system are provided inside the control terminal 1, and are connected to the internal power system;
[0043] According to the light intensity received by the photosensitive component 21 at different positions, the exposure of the high-definition camera 20 is adjusted accordingly to avoid unclear photography due to excessive light intensity. The text recognition system recognizes and enters the labels on the poles to facilitate the positioning of subsequent maintenance. The color difference comparison system can identify the rusting of iron crossarms and the deglazing of porcelain insulators. The photo map line breakage and missing recognition system can detect cracks on the poles, deformation of iron crossarms and flashover of porcelain insulators. When an abnormality is found, the abnormal part is sent to the internal power system to facilitate maintenance personnel to make timely judgments and carry out repairs. After the skin of the high-voltage cable is damaged, the current generated around the high-voltage cable will affect the supporting part of the cable (crossarms and hardware), causing its temperature to rise. The thermal imaging system can detect it in time and send a signal to the maintenance personnel to remind them. After the maintenance personnel confirm that it is correct, the device can be operated, effectively avoiding the leakage current from affecting the inspection of the device or even damaging the device.
[0044] There are two fixing seats 30, which are fixed to the other end of the semicircular frame 11 respectively. The fixing seats 30 are provided with screw holes 31, and screw rods 32 are installed through the screw holes 31;

When the pulley 43 rotates, the linkage mechanism 6 drives the control terminal 1 to move around the pole, and uses the synchronous clamping mechanism 5 to control the pulleys 43 to move closer to or farther from each other;
[0050] A disconnecting mechanism 7, which is mounted on the semicircular frame 11 and connected to the synchronous clamping mechanism 5 and the linkage mechanism 6. After the linkage mechanism 6 controls the synchronous clamping mechanism 5 to clamp the electric pole through the pulley 43, the disconnecting mechanism 7 disconnects the linkage mechanism 6 from the synchronous clamping mechanism 5;
[0051] The reset mechanism 8 is installed on the semicircular frame 11.
[0052] The synchronous clamping mechanism 5 includes a slide rail 51 provided on the semicircular frame 11, an annular plate 52 is installed in the slide rail 51, a thread 53 is provided at the bottom end of the annular plate 52, and a screw groove 54 corresponding to the thread 53 is provided on the rod 41. The annular plate 52 is divided into two halves, which are respectively arranged in the semicircular frame 11.
[0053] The slide groove 40 restricts the rod 41 to move only inside it, and the annular plate 52 is rotated. As the thread 53 on the annular plate 52 presses the screw groove 54 on the rod 41, the rod 41 simultaneously approaches or moves away from the center of the device.
[0054] The linkage mechanism 6 includes a support frame 61 installed on one of the support frames 42, a support 62 is installed on the support frame 61, a shaft 63 is installed through the support 62, a bevel gear 64 is installed at one end of the shaft 63, a bevel gear 65 is installed on the driving shaft of the motor 44, and the bevel gear 64 and the bevel gear 65 are meshed with each other, a support 66 is installed on the support 66, a shaft 67 is installed through the support 66, a bevel gear 68 is installed at the other end of the shaft 63, a bevel gear 4 69 is installed at one end of the shaft 67, and the bevel gear 3 68 and the bevel gear 4 69 are meshed with each other, and a slide rail 2 610 is provided on the semicircular frame 11, and an annular cover 611 is installed on the slide rail 2 610, and the annular cover 611 is slidably sleeved on the inner wall and the slide of the semicircular frame 11. The annular plate 611 is provided with a groove 612 on one side, and a ring rack 613 is arranged in the groove 612. A bevel gear 614 is installed at the other end of the shaft 67. The bevel gear 614 and the ring rack 613 are meshed with each other. A Z-shaped cross-section ring 615 is installed on the annular plate 52. The Z-shaped cross-section ring 615 is divided into two parts in half and respectively arranged in the semicircular frame 11. A wedge block 616 is installed on each of the Z-shaped cross-section rings 615. A support 3 617 is installed on the annular cover 611. The support 3 617 is fixed to the control terminal 1. A wedge block 2 618 is installed on the side wall of the support 3 617. The moving trajectories of the wedge block 1 616 and the wedge block 2 618 coincide. Figure 2 As shown, wedge block 1 616 and wedge block 2 618 are of the same shape and are inverted relative to each other, with their inclined surfaces being complementary.
[0055] Turn on the motor 44, and the motor 44 drives the bevel gear 2 65 to rotate. The bevel gear 2 65 drives the bevel gear 614 to rotate through the cooperation of the bevel gear 1 64, the shaft 1 63, the bevel gear 3 68, the bevel gear 4 69 and the shaft 2 67. Under the restriction of the slide rail 2 610, the bevel gear 614 drives the annular cover 611 to rotate through the annular rack 613. During the rotation of the annular cover 611, the wedge block 2 618 on the support 3 617 is driven to move synchronously. During the movement of the wedge block 2 618, its inclined surface fits with the inclined surface of the wedge block 1 616. At this time, the wedge block 2 618 is blocked by the wedge block 1 616. As the wedge block 2 618 continues to move, it drives the wedge block 1 616 to move synchronously, and then through the movement of the wedge block 1 616 on the Z-section ring 615, the annular plate 1 52 connected to the Z-section ring 615 is driven to rotate. At this time, the pulley 43 gradually approaches to clamp the electric pole.
[0056] The disconnection mechanism 7 includes an elastic member 70 installed between the Z-shaped cross-section ring 615 and the annular plate 152, an L-shaped cross-section ring 71 is fixed on the semicircular frame 11, an annular groove 72 is opened on the Z-shaped cross-section ring 615, an annular gasket 73 is arranged in the annular groove 72, an annular clamping plate 74 is installed in the annular groove 72, the inner wall of the annular clamping plate 74 is fixed to the annular gasket 73, and the outer wall is provided with a rod 2 75, the rod 2 75 has a plurality of rods, and the top end is rounded, the rounded corners can reduce the friction between the rod 2 75 and the L-shaped cross-section ring 71, and the operation is smoother;
[0057] When the pulley 43 tightly clamps the electric pole, the wedge block 1 616 on the Z-section ring 615 generates great resistance to the wedge block 2 618. As the wedge block 2 618 continues to move, the wedge block 2 618 squeezes the wedge block 1 616, and the wedge block 1 616 squeezes the elastic member 70 through the Z-section ring 615. During the downward movement of the Z-section ring 615, the annular clamping plate 74 coincides with the bottom of the L-section ring 71, and the annular gasket 73 returns to its original state, driving the annular clamping plate 74 to be clamped into the L-section ring 71, thereby limiting the Z-section ring 615. At this time, the wedge block 1 616 and the wedge block 2 618 are misaligned. When the wedge block 2 618 rotates to the other side of the semicircular frame 11, the same applies. , and the Z-section ring 615 on the other side is limited. At this time, the driving shaft of the motor 44 drives the pulley 43 to rotate, and only drives the annular cover 611 to rotate. The rotation of the annular cover 611 drives the high-definition camera 20 to rotate around the electric pole through the support three 617, so that the device rises along the electric pole while collecting information about the electric pole through the high-definition camera 20. When approaching the iron crossarm, under the action of the mechanical arm 2, the position of the high-definition camera 20 is changed. This can be achieved through the existing distance sensor, increasing the range of shooting, and slowing down the rotation speed of the driving shaft of the motor 44, so as to detect the iron crossarm and the porcelain insulator part. This part of the operation can be achieved by simply programming the control terminal 1, which is a prior art.
[0058] The elastic member 70 is a rubber sheet 701 , one side of the rubber sheet 701 is fixed to the Z-shaped cross-section ring 615 , and the other side is fixed to the annular plate 52 .
[0059] The rubber sheet 701 achieves the purpose of device operation while having low use cost.
[0060] The reset mechanism 8 includes two pressing plates 81 respectively installed on the L-shaped cross-section ring 71 , and an arc plate 82 is installed on each of the pressing plates 81 . The inner walls of the arc plates 82 are smoothed, and there is a gap between the two arc plates 82 .
[0061] After the inspection of the target is completed, it is only necessary to push the pressing plates 81 on both sides toward the center of the device. The pressing plates 81 simultaneously drive the arc plates 82 to move. There is a certain gap between the two arc plates 82 to ensure that they will not be limited by each other when moving toward the center. The rod 2 75 re-extrudes the annular gasket 73 through the annular clamping plate 74 until the rod 2 75 is separated from the L-shaped cross-section ring 71. At this time, the compressed elastic member 70 returns to its original state, driving the annular clamping plate 74 to return to its original position. Then, with the reverse rotation of the driving shaft of the motor 44, under the action of the linkage mechanism 6 and the synchronous clamping mechanism 5, the pulley 43 gradually moves away from the pole, and the device can be easily removed at this time.
[0062] The working principle of the present invention is as follows: when inspecting the target, the staff clamps the electric pole through the two-part semicircular frame 11, and then uses the screw 32 to connect the two fixing seats 30 to complete the sleeve connection of the device to the electric pole, and turns on the motor 44, the motor 44 drives the bevel gear 2 65 to rotate, and the bevel gear 2 65 drives the bevel gear 614 to rotate through the cooperation of the bevel gear 1 64, the shaft 1 63, the bevel gear 3 68, the bevel gear 4 69 and the shaft 2 67. Under the restriction of the slide rail 2 610, the bevel gear 614 drives the annular cover 611 to rotate through the annular rack 613. The annular cover 611 rotates, and the wedge block 2 618 on the support 3 617 is driven to move synchronously during the rotation process. During the movement of the wedge block 2 618, its inclined surface is in contact with the inclined surface of the wedge block 1 616. At this time, the wedge block 2 618 is blocked by the wedge block 1 616. As the wedge block 2 618 continues to move, the wedge block 1 616 is driven to move synchronously, and then the wedge block 1 616 on the Z-shaped cross-section ring 615 moves, driving the annular plate 1 52 connected to the Z-shaped cross-section ring 615 to rotate. At this time, the pulley 43 gradually approaches to clamp the electric pole;
[0063] When the pulley 43 tightly clamps the electric pole, the wedge block 1 616 on the Z-section ring 615 generates great resistance to the wedge block 2 618. As the wedge block 2 618 continues to move, the wedge block 2 618 squeezes the wedge block 1 616, and the wedge block 1 616 squeezes the elastic member 70 through the Z-section ring 615. In the default state, the rod 2 75 is squeezed by the annular gasket 73, but due to the obstruction of the L-section ring 71 to the rod 2 75, the annular gasket 73 is in a compressed state, and the Z-section ring 615 is in a compressed state. During the downward movement of the ring 615, the annular clamping plate 74 and the vacant portion of the L-shaped cross-section ring 71 are located at the same horizontal plane, the second rod 75 loses the squeezing force of the L-shaped cross-section ring 71, and the annular gasket 73 returns to its original state, driving the annular clamping plate 74 to be clamped into the L-shaped cross-section ring 71. At this time, a part of the annular clamping plate 74 is located at the vacant portion of the L-shaped cross-section ring 71, and a part is located in the Z-shaped cross-section ring 615, thereby limiting the Z-shaped cross-section ring 615. At this time, the wedge block 1 616 and the wedge block 2 618 are misaligned, and the wedge block 2 618 rotates When it reaches the semicircular frame 11 on the other side, similarly, the Z-shaped cross-section ring 615 on the other side is limited. At this time, the motor 44 driving shaft drives the pulley 43 to rotate, and only drives the annular cover 611 to rotate. The rotation of the annular cover 611 drives the high-definition camera 20 to rotate around the electric pole through the support three 617, so that the device rises along the electric pole while collecting information about the electric pole through the high-definition camera 20. When it is close to the iron cross arm, under the action of the mechanical arm 2, the position of the high-definition camera 20 is changed. This operation can be achieved through the existing distance sensor to increase the shooting range and slow down the rotation speed of the motor 44 driving shaft to detect the iron cross arm and the porcelain insulator part. This part of the operation can be achieved by simply programming the control terminal 1. It is a prior art. After the iron cross arm and the porcelain insulator are detected, the distance between the high-definition camera 20 and the cable is closer than the ground. The mechanical arm 2 can control the high-definition camera 20 to shoot the cable, and the infrared thermal imaging system can be combined to perform more accurate detection of the cable part.
[0064] After all targets have been checked, the motor 44 rotates in the opposite direction, driving the device to descend and approach the ground again, and stops when it descends to the same height as the inspector's arm. At this time, it is only necessary to push the pressing plates 81 on both sides toward the center of the device. Under the squeezing of the arc plate 82, the rod 2 75 re-squeezes the annular gasket 73 through the annular clamping plate 74 until the rod 2 75 is separated from the L-shaped cross-section ring 71. At this time, the compressed elastic member 70 returns to its original state, driving the annular clamping plate 74 to return to its original position. Subsequently, as the driving shaft of the motor 44 rotates in the opposite direction, under the action of the linkage mechanism 6 and the synchronous clamping mechanism 5, the pulley 43 gradually moves away from the pole, and the device can be easily removed at this time.

[0067] The elastic member 70 includes a spring 7001 installed between the Z-shaped cross-section ring 615 and the annular plate 52. A telescopic rod 7002 is installed through the axis of the spring 7001. One end of the telescopic rod 7002 is fixed to the Z-shaped cross-section ring 615, and the other end is fixed to one side of the annular plate 52.
[0068] The coordinated use of the telescopic rod 7002 and the spring 7001 has the same effect as the rubber sheet 701 and is more stable.
[0069] The photosensitive component 21 on the high-definition camera 20 is flip-up.
[0070] During the inspection of a single target, the position of the light irradiating the utility pole and its mounting components changes very little. If the photosensitive component 21 is exposed for a long time, its service life will be greatly shortened. The photosensitive component 21 adjusts the exposure of the high-definition camera 20 according to the light intensity received at different positions. The flip-type photosensitive component 21 only needs to flip over and stop working after the high-definition camera 20 rotates around the utility pole once. Then the exposure component can be automatically adjusted according to the position of the previous rotation. This part of the operation can be achieved through simple programming, which is a prior art, thereby extending the service life of the device.
[0071] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0072] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
