Description

Technical Field

[0001] The present invention relates to the technical field of power line measurement, and in particular to a power line measurement device and a measurement method. Background Art

[0002] With the development of science and technology, people's demand and dependence on electricity are getting higher and higher. As a major mode of power transportation, the distance parameters of power lines, such as the distance between power lines and the ground, the crossing distance between power lines and other power lines, and the distance between power lines and buildings and trees, have an important impact on people's life safety.

[0003] At present, in the operation and maintenance of overhead power lines and line inspections, the distance parameters of power conductors are measured live. The measurement method is mainly to use an insulated measuring rope, an insulated measuring rod or a theodolite to measure the distance parameters of power conductors. Although the insulated measuring rope and the insulated measuring rod are simple to operate and the technical content is not very high, such an operation method has high labor intensity and it is difficult to achieve effective measurement for cables with high overhead degrees. The method of measuring power conductors by theodolite is difficult to operate due to the wide cable laying area, and the overall data precision is low, so the reference value is relatively limited. To address this problem, the existing design method is to transport a measuring device with a walking function to the cable by an unmanned aerial vehicle, and perform data measurement by walking the measuring device on the cable. For example, the existing public document CN106970389B-Power Line Measuring Device and Power Line Measuring Method discloses a walking power line measuring device, but the measuring device still has the following certain deficiencies in actual use:

[0004] 1. The existing power line measurement device can only detect the distance between the line and the obstacles below, so as to avoid the influence of obstacles below the line on power transmission, but it is not applicable to the distance between adjacent lines and the distance of the concave caused by long-term use of the line. The above detection data has a great impact on the line. The lack of these data reduces the significance of the line measurement results;

[0005] 2. The existing power line measurement device uses the method of walking on the line to measure. When encountering strong winds, this measurement method is very likely to cause the measurement device to shake or even fall, posing a great safety hazard;

[0006] Therefore, it is necessary to improve the prior art to solve the above problems. Summary of the invention

[0007] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0008] In view of the problem that the above-mentioned existing power line measuring device cannot accurately measure the relevant data between adjacent lines in actual use, a power line measuring device is proposed.

[0010] The beneficial effects of the present invention are as follows: when the power line measuring device is in use, after the traveling mechanism is engaged with a cable, the measuring mechanism rotates with the rotating shaft as the axis, and the free end of the measuring mechanism is mounted on the adjacent cable. As the traveling mechanism moves along the cable, the measuring mechanism will also move synchronously. Through the cooperation of the semicircular arc rod and the second spring, the semicircular arc rod is always hooked on the cable. Through the setting of the first ranging sensor, the relative distance between the T-shaped rod and the fixed rod can be detected, and the distance change between adjacent wires can be measured.

[0016] Another beneficial effect of the present invention is that when the power line measuring device is in use and encounters strong winds, the wind wing plate will rotate with the fifth rotating column as the axis according to the blowing force provided by the wind. Under the action of the rotation, the traction rope will provide a pulling force. Under the action of the pulling force, the moving block continues to move upward along the rectangular through groove.

[0046] When the above arrangement is in use, the second rotating column 104a can drive the second toothed disc 104a-1 to rotate through the operation of the motor 104, and the two first toothed discs 102a-1 can be rotated synchronously and in the same direction through the transmission of the chain 103, thereby achieving the synchronous and same-direction rotation of the two first working wheels 102, so as to realize the walking of the entire walking mechanism 100 on the cable.

[0047] Furthermore, a rectangular through-groove 101b for clearance fit of the moving block 302 is provided on the vertical rod of the T-shaped plate 101 in the vertical direction, and a first guide column 101b-1 is slidably sleeved on the moving block 302. The setting of the first guide column 101b-1 serves as a limit guide when the moving block 302 moves, and the two ends of the first guide column 101b-1 are respectively fixedly connected to the upper and lower end surfaces of the rectangular through-groove 101b, and a first spring 101b-2 is slidably sleeved on the first guide column 101b-1 located below the moving block 302.

[0048] When the above arrangement is in use, the first electromagnetic plate 101c is energized to generate magnetism to adsorb the moving block 302, so that a certain distance is maintained between the second work-shaped wheel 301 and the first work-shaped wheel 102, which is convenient for the staff to match the first work-shaped wheel 102 on the cable. After the matching is completed, the first electromagnetic plate 101c is powered off, and under the action of the first spring 101b-2 resetting, the moving block 302 drives the two second work-shaped wheels 301 to move upward and match under the cable, so as to achieve the role of limiting guidance during walking.

[0049] See Fig. 9 and Fig.10 As shown, a T-shaped slot 201c with an open end for slidingly sleeved T-shaped rod 202 is provided on the fixed rod 201, and a second spring 201c-1 is slidably sleeved on the T-shaped rod 202 located inside the T-shaped slot 201c. The second spring 201c-1 can provide a reset force for the position of the T-shaped rod 202.

[0050] When the above arrangement is in use, the semicircular arc rod 202b is hooked on the cables adjacent to the traveling cables and moves synchronously with the movement. When the distance between the cables changes, the T-shaped rod 202 moves accordingly in the T-shaped slot 201c, and the first ranging sensor 201c-2 can detect the changes in the T-shaped rod 202 to collect the distance change data of the two cables.

[0052] In addition, it should be noted that when the drone is mounted, the T-bar 202 can be kept in a stretched state by its own gravity, so there is no need to consider that the measuring mechanism 200 cannot be mounted on adjacent cables due to the length limitation.

By setting the linear change of the depth of the ranging arc groove 203a-1, the second ranging sensor 203d can detect the rotation angle and indirectly measure the height difference between the two cables. Preferably, the second ranging sensor 203d is an infrared ranging sensor.

[0055] Furthermore, a baffle 203c is fixedly provided on the top surface of the T-shaped rod 202 on the side of the fixing sleeve 201a away from the first I-shaped wheel 102, and the baffle 203c can limit the fixing rod 201 to prevent the fixing rod 201 from rotating to the other side away from the cable to be overlapped.

[0059] In actual use, the layout of the electrical components in the control box 400 should make the entire device in a balanced state, and except for the electrical components, other structures should be made of insulating materials, and the surface of the electrical components should also be insulated;

[0060] In addition, in actual use, the control box 400 may also be designed with an insulating rope as described in the existing public document CN106970389B to measure the distance to the obstacle below, and its working principle may refer to the document. Example 2

[0066] When the above arrangement is in use, when strong winds occur, after the wind blows on the wind wing plate 303, it will cause the wind wing plate 303 to drive the rotating rod 303a to rotate in the vertical direction with the fifth rotating column 305a as the axis. At the same time, the traction rope 304c at the other end of the fifth rotating column 305a will provide an upward traction force to the moving block 302, so that the clamping rod 301b can rotate at a certain angle with the fixed column 302b as the axis. During the rotation of the clamping rod 301b, the two second engineering wheels 301 are tightened with each other and staggered with the first engineering wheel 102, so as to tighten the cable and protect the entire device. Example 3

[0067] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7 , which is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but is different in that this embodiment is proposed in order to keep the traction rope 304c always in a tensioned state, thereby ensuring that it can be effectively locked in subsequent windy weather.

[0068] Specifically, a third I-shaped wheel 304 for winding a traction rope 304c is provided at the upper end position on the other side of the rectangular through groove 101b on which the second I-shaped wheel 301 is provided, and the third I-shaped wheel 304 is slidably sleeved on the fourth rotating column 304a, and this arrangement can realize the free rotation of the third I-shaped wheel 304, and both ends of the fourth rotating column 304a are slidably sleeved with the second guide column 304b-1, and this arrangement can realize the movement of the fourth rotating column 304a in the axial direction of the second guide column 304b-1, one end of the second guide column 304b-1 is fixedly connected to the inner end surface of the U-shaped plate 304b, and the open end of the U-shaped plate 304b is fixedly connected to the T-shaped plate 101, and a third spring 304b-2 is slidably sleeved on the second guide column 304b-1 between the fourth rotating column 304a and the T-shaped plate 101, and the arrangement of the third spring 304b-2 can realize the reset of the position of the fourth rotating column 304a;

[0069] The two ends of one side of the moving block 302 are symmetrically fixed with blocking bars 302a. When the first electromagnetic plate 101c is powered off, the upper end of the blocking bar 302a abuts against a side surface of the fourth rotating column 304a close to the T-shaped plate 101 to limit the fourth rotating column 304a.

[0070] When the above arrangement is in use, when the device as a whole is ready to cooperate with the cable, the moving block 302 will move downward, and at this time, the blocking bar 302a will move downward synchronously to contact the limit of the fourth rotating column 304a, and the traction rope 304c will be wound around the third work-shaped wheel 304. As the moving block 302 moves downward, the traction rope 304c will also give the third work-shaped wheel 304 an extrusion force, so that the fourth rotating column 304a can slide on the second guide column 304b-1. The distance of the traction rope 304c released by the change in the position of the third work-shaped wheel 304 can be used to compensate for the distance change when the moving block 302 moves downward;

[0071] When the entire device has been engaged on the cable and encounters strong winds, the blocking bar 302a abuts against one side of the fourth rotating column 304a to limit the third wheel 304, so that the traction rope 304c can be kept in a tensioned state as a whole. When strong winds provide traction to the traction rope 304c, the traction rope 304c can quickly respond to the moving block 302 by traction. Example 4

[0072] Reference Fig. 9 , which is the fourth embodiment of the present invention, is based on any of the above embodiments, except that, in order to facilitate the staff to transport the entire device by drone after measurement, this embodiment is proposed.

[0073] Specifically, a second mounting plate 201b-1 is fixedly disposed on the outer side wall of one end of the fixing rod 201 close to the T-shaped rod 202, and a third mounting plate 202a-1 is fixedly disposed on the outer side wall of one end of the T-shaped rod 202 close to the semicircular arc rod 202b. The second mounting plate 201b-1 and the third mounting plate 202a-1 are aligned on the side close to each other and are respectively fixedly disposed with a second electromagnetic plate 201b and a magnetic plate 202a, and the side close to each other of the second electromagnetic plate 201b and the magnetic plate 202a are arranged in the same manner.

[0074] When the above-mentioned arrangement is in use, after the device completes the measurement of the cable, the staff controls the second electromagnetic plate 201b to be energized. Under the effect of like-charge repulsion, a thrust is generated on the magnetic plate 202a, thereby enabling the third mounting plate 202a-1 to drive the T-shaped rod 202 to move to a position away from the fixed rod 201, so as to achieve the separation between the semi-circular arc rod 202b and the cable, thereby facilitating the cooperation between the drone and the semi-circular arc rod 202b.
