The upper portion of the mounting slot 22 is in an arc shape with an opening downward, and the limit frame 19 is installed in the mounting slot 22. The upper portion of the limit frame 19 is in an arc shape that matches the upper portion of the mounting slot 22. The left baffle 20 is fixedly installed on the inner side of the left portion of the limit frame 19.

The central axis 21 is rotatably installed in the axial hole 23, and a central axis 21 is fixedly installed on the right end of the central axis 21, which can rotate in the mounting slot 22. A movable swing seat is provided, and a sliding cavity with an opening downward is provided on the lower side of the swing seat. A slider 24 with its lower end located below the swing seat is slidably installed in the sliding cavity. An elastic reset member 25 is provided between the upper side of the slider 24 and the upper inner wall of the sliding cavity.

[0043] Embodiment 6: As an optimization of the above embodiment, as shown in the attached Figures 1 to 8As shown in Figures 11, the swing seat includes a left mounting plate 29 and a right mounting plate 30. The left mounting plate 29 is fixedly mounted on the right end of the central shaft 21 and is mounted on the inner side of the upper part of the mounting groove 22.

A conical left swing plate 31 with a larger upper part and a smaller lower part is fixedly mounted on the lower side of the left mounting plate 29. A slide groove 32 opening to the right is provided on the lower side of the left swing plate 31. A front limit block 33 and a rear limit block 34 are fixedly mounted on the inner side of the lower part of the slide groove 32 at intervals. The slider 24 is slidably mounted between the front limit block 33 and the rear limit block 34, corresponding to the front limit block 33. A front limit plate 35 is fixedly installed on the front side of the slider 24 at the upper position, and a rear limit plate 36 is fixedly installed on the rear side of the slider 24 at the upper position of the rear limit block 34. The upper conductive sheet 28 is fixedly installed on the lower side of the front limit plate 35 and / or the lower side of the rear limit plate 36. The lower conductive sheet 27 is fixedly installed on the upper side of the front limit block 33 and / or the upper side of the rear limit block 34. The elastic reset member 25 is arranged between the upper side of the slider 24 and the inner side of the upper part of the slide groove 32. The right mounting plate 30 is fixedly installed on the right side of the left mounting plate 29, and the left side of the right mounting plate 30 and the inner wall of the slide groove 32 form a sliding cavity.

[0044] According to the requirements, the upper conductive sheet 28 is fixedly installed on the lower side of the front limit plate 35 and the lower side of the rear limit plate 36, and the lower conductive sheet 27 is fixedly installed on the upper side of the front limit block 33 and the upper side of the rear limit block 34, so that the slider 24 can avoid tilting during the up and down movement. During use, the front limit block 33 and the rear limit block 34 can limit the slider 24 to prevent the slider 24 from falling. The left mounting plate 29 and the left swing plate 31 are integrally arranged. The structure in which the left mounting plate 29 and the left swing plate 31 are fixed together is the same as the structure of the right mounting plate 30. The setting of the right mounting plate 30 can form a sliding cavity with the slide groove 32, thereby constraining the slider 24 to prevent the slider 24 from separating from the slide groove 32 after moving to the right. At the same time, the right mounting plate 30 can protect the slider 24 to prevent rain, snow or wind and sand from entering the slide groove 32 and affecting the up and down movement of the slider 24, so that the slide groove of the slider 24 The inner wall of 32 cannot contact with the outer side of the upper part of the transmission line 3, and the elastic reset member 25 makes the inner wall of the slide groove 32 of the slider 24 always against the outer side of the upper part of the transmission line 3. When the inner wall of the wire supporting groove 15 of the support plate 11 is worn to the set value, the slider 24 moves downward under the action of the elastic reset member 25, so that the upper conductive sheet 28 and the lower conductive sheet 27 contact with each other. When the upper conductive sheet 28 and the lower conductive sheet 27 contact with each other, the connection switch is turned on, and the processing module sends a wear signal to the control module through the second wireless transceiver module and the first wireless transceiver module. At this time, the wear amount of the inner wall of the wire supporting groove 15 of the support plate 11 has reached the set value, and maintenance personnel are required to perform maintenance.

[0046] During use, when the left mounting plate 29 and the right mounting plate 30 are swinging, the swing limit block 37 abuts against the front inner wall and the rear inner wall of the swing groove 38, which can play a limiting role to prevent the transmission line 3 and the slide groove 32 from separating from each other after the left mounting plate 29 and the right mounting plate 30 swing too much, resulting in the inability to continue measuring the vibration data of the transmission line 3 and the wear data of the inner wall of the cable support trough 15.

[0047] Embodiment 8: As an optimization of the above embodiment, as shown in the attached Figure 7 , 11 As shown, two guide grooves 39 with downward openings are provided at intervals at the front and rear of the upper inner wall of the slide groove 32, and each guide groove 39 is provided with a guide column 40 whose lower end is fixedly installed with the upper side of the slider 24, and the outer side of the guide column 40 corresponding to the position between the inner side of the guide groove 39 and the upper side of the slider 24 is provided with an elastic reset member 25.

[0048] According to the requirements, the elastic reset member 25 is a known compression spring. During use, by setting the guide column 40 and the guide groove 39, it is possible to prevent the slider 24 from swinging back and forth during the up and down movement, causing the upper conductive sheet 28 and the lower conductive sheet 27 to accidentally contact and transmit a signal to the processing module. Through such a setting, the accuracy of the measurement result of the wear measurement device can be improved.

[0049] Embodiment 9: As an optimization of the above embodiment, as shown in the attached Figures 1 to 13 As shown, the method for using the transmission line wear monitoring device comprises the following steps: Step 1: Install the mounting base 1 and the connecting frame 2 on the power grid tower; Step 2: After placing the transmission line 3 in the wire support groove 15 of the support plate 11, the support plate 11 and the fixing block 4 are installed together through the lower connecting ear plate 13; Step 3, insert the upper part of the transmission line 3 into the limiting groove 10 and the upper clamping groove 26 respectively; Step 4: When the transmission line 3 sways and vibrates, the transmission line 3 drives the slider 24 and the base 16 to rotate, and the vibration sensor detects the number of swings; Step 5: When the upper guide sheet and the lower conductive sheet 27 are in contact with each other and the wear amount of the inner wall of the wire support groove 15 of the support plate 11 reaches a set value, the processing module sends a signal to the control module through the second wireless transceiver module and the first wireless transceiver module, and the staff replaces the support plate 11 according to the received signal; Or / and, when the number of swings reaches a set value, the processing module sends a signal to the control module through the second wireless transceiver module and the first wireless transceiver module, and the staff replaces the pallet 11 according to the received signal.

[0050] First, install the mounting base 1 and the connecting frame 2 on the power grid tower, and install the fixing block 4 under the connecting frame 2 through the upper connecting ear plate 5; then fix the fixing block 4 with the support plate 11 through the lower hinge shaft 14 and the lower connecting ear plate 13, so that the transmission line 3 is supported in the wire supporting groove 15 of the support plate 11, and at the same time, the transmission line 3 is respectively inserted into the limiting groove 10 and the upper clamping groove 26 to ensure that the transmission line 3 will not fall off from the support plate 11 and the fixing block 4. At this time, the fixing plate 12 and the support plate 11 will not deflect and remain stable; then install the vibration sensor on the left side of the fixing block 4 so that The vibration sensor probe is located above and behind the horizontal plate 7. When the transmission line 3 vibrates and swings, it will drive the clamping block 6 to rotate along the central axis 21, thereby ensuring that each swing of the transmission line 3 can be monitored; the wear measurement component is installed on the right side of the fixed block 4. After the slider 24 moves downward under the action of the elastic reset member 25, the transmission line 3 is clamped in the upper clamping groove 26. The elastic reset member 25 presses the upper end of the slider 24 to ensure that the slider 24 and the transmission line 3 will not fall off. When the wire support groove 15 of the support plate 11 is worn, the slider 24 moves downward under the action of the elastic reset member 25.

[0051] In an environment where strong winds, heavy rains, dust, ice and snow can cause the transmission line 3 to sway and vibrate, the transmission line 3 drives the block 6 and the slider 24 to rotate, so that the vibration sensor monitors the number of swings of the transmission line 3 according to the position change of the horizontal plate 7. When the inner wall of the wire support groove 15 of the support plate 11 wears and becomes thinner, the upper conductive sheet 28 and the lower conductive sheet 27 contact each other after the slider 24 moves downward, the connection switch is turned on, and the processing module sends a signal to the control module through the second wireless transceiver module and the first wireless transceiver module. The staff can replace parts in time according to the signals received by the control module.

[0052] During the monitoring process, the number of swings and the amount of wear can be continuously collected. When the number of swings reaches the set value, the processing module also sends a signal to the control module through the second wireless transceiver module and the first wireless transceiver module. The staff can predict the amount of wear at this time based on the signal received by the control module, and can accurately obtain the amount of wear on the inner wall of the support plate 11 wire support groove 15, so as to facilitate timely replacement of parts.

[0053] The above technical features respectively constitute various embodiments of the present invention, which have strong adaptability and implementation effect. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.
