Description

[0002] To ensure the safe operation of power equipment, it is necessary to inspect and maintain its status. By assessing the safety and economic reliability of power equipment during operation, the economic benefits of power companies can be continuously improved. Regular inspections of high-voltage transmission lines are even more important, as they are responsible for supplying power over a large area.

[0003] In this regard, China has authorized a patent, authorization announcement number: CN115542197B, which proposes a power line detection method. Through the linked clamping mechanism and detection component, the high-definition video acquisition equipment performs circular motion while the device moves along the length of the line, so as to detect the line in all directions and at all angles, ensuring the accuracy of the detection results.

[0045] See also Figure 1 In an embodiment of the present invention, a power line detection method includes the following steps:

[0046] Step 1: Evaluate the safety level of the power line based on the dance map and severe climate distribution map of the area where the line is located, and formulate a power line inspection plan based on the safety level evaluation results;

[0047] Step 2: Conduct on-site field survey and develop on-site testing procedures;

[0048] Step 3: According to the inspection process, the maintenance personnel carry the inspection equipment to the height of the power line, and then mount the inspection equipment on the power line;

[0049] Step 4: Start the detection equipment so that it can move along the power line and take pictures of the power line;

[0050] Step 5: Integrate and evaluate the video footage captured by the detection equipment to determine whether the power lines need to be replaced or repaired.

[0051] See also Figure 2 、 Figure 5, wherein the detection equipment includes: a counterweight base 1, a clamping mechanism and a recording mechanism, so that in the process of rotating the handwheel 25, the cam 11 can cooperate with the cylindrical spring 8 to drive the slider 5 and the abutment wheel 6 to move away from or close to the groove wheel 3, thereby achieving the clamping or release of the power line, reducing the difficulty of mounting the equipment on the power line, and improving the safety of high-altitude operations for maintenance personnel. At the same time, under the action of two sets of two-way transmission components, the two wide-angle cameras 24 can cooperate to take a more comprehensive picture of the line to avoid missing shots. At the same time, the two connecting covers 21 move more smoothly, avoiding jamming and stuck phenomena, and improving the stability of equipment operation.

[0052] Specifically, the clamping mechanism is provided on the counterweight base 1, and the clamping mechanism includes a mounting assembly and an operating assembly. The mounting assembly can suspend the counterweight base 1 on the line, and the operating assembly cooperates with the mounting assembly to separate the power line from the counterweight base 1.

[0053] The mounting assembly includes a vertical plate 2 symmetrically arranged on the counterweight base 1, and a sheave 3 is rotatably mounted on one end of the vertical plate 2 away from the counterweight base 1;

[0054] The mounting assembly also includes two energy storage structures symmetrically arranged on the counterweight base 1, and an abutment wheel 6 is rotatably installed on one end of the energy storage structure away from the counterweight base 1, and the abutment wheel 6 is adapted to the groove wheel 3. The energy storage structure includes two side plates 4 fixedly mounted on the counterweight base 1, and the side plates 4 are provided with a slide groove 401 along the length direction thereof. A slider 5 is slidably installed in the slide groove 401, and the slider 5 is rotatably connected to the abutment wheel 6;

[0055] The slider 5 is slidably connected to the vertical shaft 7 provided in the chute 401. The vertical shaft 7 is sleeved with a cylindrical spring 8. One end of the cylindrical spring 8 is connected to the slider 5, and the other end is connected to the side wall of the chute 401.

[0056] The operating assembly includes a follower frame 9 fixedly connected to the slider 5, a rectangular through slot is formed in the middle of the follower frame 9, and a lower pressing plate 10 is provided at the bottom of the rectangular through slot;

[0057] The operating assembly further includes a hand wheel 25 rotatably mounted on the counterweight base 1 . A cam 11 is fixed to the rotating shaft of the hand wheel 25 . The cam 11 is in sliding contact with the lower pressing plate 10 .

[0058] In the initial state, the abutment wheel 6 will maintain a rolling abutment state with the groove wheel 3 under the action of the elastic force of the column spring 8. At this time, the lower pressure plate 10 is in a state of abutment with the short axis of the cam 11. When the device needs to be mounted on the power line, it is necessary to manually turn the handwheel 25 to rotate the handwheel 25. During the rotation of the handwheel 25, the handwheel 25 will drive the cam 11 to rotate, and the position where the cam 11 abuts against the lower pressure plate 10 will change from the short axis of the cam 11 to the long axis of the cam 11. In this process, the lower pressure plate 10 will move toward It moves toward the counterweight base 1, and at the same time, the follower frame 9 will separate the abutment wheel 6 from the groove wheel 3 by driving the slider 5 toward the counterweight base 1, and further compress the cylindrical spring 8. At this time, the power line to be detected can be placed between the groove wheel 3 and the abutment wheel 6, so that when the cam 11 is reversed or continues to rotate, the cylindrical spring 8 can push the abutment wheel 6 upward again by releasing the elastic potential energy until the abutment wheel 6 abuts against the power line, so that the power line is clamped between the groove wheel 3 and the abutment wheel 6, and the device is mounted on the power line.

[0059] Through the above-mentioned arrangement, during the rotation of the handwheel 25, the cam 11 can cooperate with the cylindrical spring 8 to drive the slider 5 and the abutment wheel 6 to move away from or close to the groove wheel 3, thereby clamping or releasing the power line, reducing the difficulty of mounting the equipment on the power line, and improving the safety of high-altitude operations for maintenance personnel performing high-altitude operations.

[0060] Among them, the setting of the counterweight base 1 can make the center of gravity of the equipment as low as possible, so that the equipment is more stable when mounted on the power line and has better wind resistance.

[0061] See also Figures 2 to 4 、 Figures 6 to 8 The recording mechanism is mounted on the counterweight base 1 and connected to the clamping mechanism. The recording mechanism includes a power assembly and two sets of bidirectional transmission assemblies. The power assembly can drive the bidirectional transmission assembly and the mounting assembly to move. The two sets of bidirectional transmission assemblies are connected by a linkage rod 26, and the two sets of bidirectional transmission assemblies are diagonally arranged.

[0062] The power assembly includes a driving device 12 fixedly mounted on the counterweight base 1, and the output of the driving device 12 is connected to one of the sheaves 3 through a transmission belt 13;

[0063] The power assembly also includes a turntable 14 coaxially fixedly connected to the output shaft of the driving device 12 and a lifting plate 16 provided on the counterweight base 1. The lifting plate 16 and the turntable 14 are connected by a chimeric structure. The chimeric structure includes a retardation block 15 rotatably mounted at an eccentric position of the turntable 14 and a retardation groove 1601 provided along the length direction of the lifting plate 16. When the turntable 14 rotates, the retardation block 15 can move along the length direction of the retardation groove 1601.

[0064] The lifting plate 16 is connected to the bidirectional transmission assembly via a telescopic plate;

[0065] The telescopic plate includes a fixed sleeve 17 fixedly mounted on the counterweight base 1. The interior of the fixed sleeve 17 is a hollow structure, and a lifting rod 18 is slidably installed in the fixed sleeve 17. One end of the lifting rod 18 passes through the fixed sleeve 17 and is connected to the lifting plate 16, and the other end is connected to the bidirectional transmission assembly;

[0066] The bidirectional transmission assembly includes two guide members 23 provided on the counterweight base 1. The guide members 23 are provided with a straight groove 2301 and a circular groove 2302 along their length, and the straight groove 2301 and the circular groove 2302 form a guide groove.

[0067] The bidirectional transmission assembly further includes a connecting cover 21 disposed between the two guide members 23, a wide-angle camera 24 being disposed in the connecting cover 21, and two pulleys 22 being rotatably mounted on each end of the connecting cover 21, the two pulleys 22 being capable of rolling in the guide groove;

[0068] A cross bar 20 is rotatably mounted on the connection cover 21 , and the cross bar 20 is slidably connected to a connection sleeve 19 fixed to an end of the lifting rod 18 away from the lifting plate 16 .

[0069] After the device is mounted on the power line, the drive device 12 is controlled to work. At this time, the output shaft of the drive device 12 will drive one of the sheaves 3 to rotate through the transmission belt 13, so that when the sheave 3 rotates, the device can move along the power line. At the same time, when the drive device 12 is working, the output shaft of the drive device 12 will drive the turntable 14 to rotate, so that the delay block 15 set at the eccentric position of the turntable 14 performs a circular motion, and the delay block 15 is slidably set in the delay groove 1601, so that when the delay block 15 performs a circular motion, the lifting plate 16 can reciprocate along the length direction of the fixed sleeve 17, thereby driving the connecting sleeve 19 on one set of the two-way transmission components to move. At the same time, since the two sets of two-way transmission components are connected by the linkage rod 26, the two connecting sleeves 19 will move synchronously;

[0070] Furthermore, in the initial state, the connecting covers 21 on the two groups of two-way transmission components are at the lowest point of the stroke. At this time, the connecting covers 21 on one group of two-way transmission components are in the arc groove body 2302, and the connecting covers 21 on the other group of two-way transmission components are in the straight groove body 2301. When the connecting sleeve 19 moves upward, the connecting cover 21 in the arc groove body 2302 will move from the arc groove body 2302 to the straight groove body 2301, and the connecting cover 21 in the straight groove body 2301 will move from the straight groove body 2301 to the arc groove body 2302. The two groups of connecting covers 21 work together to drive the two groups of wide-angle cameras 24 to move, and take a more comprehensive picture of the line.

[0071] Through the above-mentioned setting, under the action of two sets of two-way transmission components, the two wide-angle cameras 24 can cooperate with each other to take a more comprehensive picture of the line, avoiding the phenomenon of missing pictures. At the same time, the two connecting covers 21 move more smoothly, avoiding the phenomenon of jamming and freezing, and improving the stability of equipment operation.
