DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application are described clearly and completely below. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work also belong to the scope of protection of the present application.

[0035] Reference Figures 1 to 5 As shown in the drawings, the cable breakage monitoring device provided by the present application comprises a loading base plate 1 mounted on a carrier, two groups of pulling assemblies are arranged on the loading base plate 1, the two groups of pulling assemblies limit a support 2 on the loading base plate 1, a driving mechanism 7 is arranged on the support 2 and the loading base plate 1, and a clamping assembly 5 is fixedly arranged on the top of the support 2. The driving mechanism 7 is used to drive the clamping assembly 5 and, after the clamping assembly 5 completes cable clamping and fixing, to drive the pulling assemblies to release the limiting connection between the support 2 and the loading base plate 1.

[0036] When installing, the loading base plate 1 is installed at a specified position of the carrier to ensure that the connection between the loading base plate 1 and the carrier is firm. Then the support 2 is placed on the loading base plate 1 and is limited and fixed by the two groups of pulling assemblies to ensure that it remains stable during flight transportation and installation.

[0037] The starting carrier flies to the cable hanging point, after reaching the specified position, the carrier adjusts the posture of the clamping assembly 5, so that the clamping assembly 5 is aligned with the cable, and finally the cable falls into the inside of the clamping assembly 5. After the cable falls into the inside of the clamping assembly 5, the driving mechanism 7 is started, so that the clamping assembly 5 firmly clamps the cable. In the process of clamping the cable, the driving mechanism 7 synchronously drives the pulling assembly. When the clamping assembly 5 completes the clamping action on the cable, the pulling assembly releases the limiting connection between the support 2 and the loading base plate 1, so that the support 2 is separated from the loading base plate 1 and is hung on the cable only by the clamping assembly 5. At this time, the carrier is disconnected with the monitoring device, and the self-loading of the device is realized. The whole process is coordinated and controlled by the driving mechanism 7, so as to ensure the timing and reliability of the clamping and releasing actions, thereby ensuring the stable loading and efficient deployment of the cable fracture monitoring device.

[0038] It should be noted that the carrier in the present scheme is preferably a drone, which has high-precision positioning and stable hovering capability.

[0039] The driving mechanism 7 includes a driving assembly and a linkage assembly, the driving assembly is installed on the loading base plate 1 and is used to drive the linkage assembly, and the linkage assembly is arranged in the support 2 and is connected with the driving assembly.

[0040] In the present embodiment, after the driving assembly is started, the linkage assembly responds and transmits power to the clamping assembly and the pulling assembly. The driving assembly controls the output timing accurately, first drives the linkage assembly to complete the clamping action on the cable, ensures that the clamping force reaches the preset value and remains stable. At the same time, power is transmitted to the pulling assembly synchronously during the clamping action, and the linkage assembly releases the limiting between the support 2 and the loading base plate 1 at the moment when the clamping assembly 5 completes the clamping, so that the support 2 is completely separated from the loading base plate 1.

[0041] Optionally, the linkage assembly includes a U-shaped chamber 4 fixedly arranged in the support 2, a lead screw 71 is rotatably arranged in the U-shaped chamber 4, a transmission nut 72 is screw-connected in the lead screw 71, first connecting rods 73 are symmetrically arranged on both sides of the transmission nut 72, one end of a second connecting rod 74 is rotatably arranged on the first connecting rod 73 through a first shaft seat, and the other end of the second connecting rod 74 is rotatably connected with the clamping assembly 5.

[0042] The first connecting rod 73 is provided with a third connecting rod 77 at an end away from the transmission nut 72, and the third connecting rod 77 is connected with the pulling assembly.

[0043] In this embodiment, the rotation of the lead screw 71 drives the transmission nut 72 to move linearly. During the linear movement, the transmission nut 72 drives the first connecting rod 73 to push the second connecting rod 74 to rotate around the first shaft seat, thereby driving the clamping assembly 5 to realize clamping action. At the same time, the movement of the first connecting rod 73 drives the third connecting rod 77 to displace, and the power is transmitted to the pulling assembly, so that the pulling assembly is triggered to move synchronously at the moment when the clamping is completed, and the limiting connection between the support 2 and the loading base plate 1 is released. The whole process realizes precise timing control through mechanical linkage, ensures that the clamping is released after the clamping is stable, effectively avoids the device from falling off due to misoperation, and improves the mounting reliability and safety.

[0044] Optionally, the pulling assembly comprises a sliding rod 78 fixedly arranged at one end of the support 2, a sliding block 75 slidably sleeved on the sliding rod 78, and one end of a limiting pull rope 76 hookingly arranged on the sliding block 75, and the other end of the limiting pull rope 76 is fixedly arranged on the loading base plate 1.

[0045] The third connecting rod 77 is connected with the sliding block 75.

[0046] In this embodiment, the third connecting rod 77 moves synchronously with the first connecting rod 73, pushes the sliding block 75 to slide along the sliding rod 78, and the sliding block 75 pushes the limiting pull rope 76 hookingly arranged on the sliding rod 78 to gradually move during the sliding process. At the moment when the clamping assembly completes the clamping action, the sliding block 75 moves to the release position of the limiting pull rope, that is, the buckle of the limiting pull rope 76 is separated from the limiting end of the sliding rod 78, so that the limiting pull rope 76 is completely separated, thereby releasing the fixed constraint between the support 2 and the loading base plate 1. At this time, the support 2 is only connected with the cable through the clamping assembly 5 under the action of the clamping force, and the suspension state is realized.

[0047] The whole release process is strictly synchronized with the clamping action, so that the mechanical limiting is released only after the clamping is stable, and the risk of equipment falling caused by premature loosening is avoided. Through the linkage structure design, the sequence and automatic control of the mounting process are realized, and the safety and operation convenience of the device installation are greatly improved.

[0048] It should be noted that in actual application, the length of the sliding rod 78 and the pre-tensioning stroke of the limiting pull rope 76 need to be accurately matched according to the closing clamping stroke of the clamping assembly 5, so as to ensure that the displacement of the sliding block 75 is synchronized with the action stroke of the clamping assembly 5.

[0049] When the support 2 is installed on the loading base plate 1, the operator only needs to hook one end of the limiting pull rope 76 to the sliding rod 78 to complete the temporary fixing of the support 2 and the loading base plate 1.

[0050] Optionally, the clamping assembly 5 comprises two groups of L-shaped seats 51 fixedly arranged at the top of the support 2, the L-shaped seats 51 are provided with limiting sliding grooves 52 in the vertical side of the support 2, the sliding plate 53 is slidingly arranged in the limiting sliding grooves 52, the sliding plate 53 is rotatably connected with the second connecting rod 74 through the second shaft seat close to one side of the U-shaped chamber 4;

[0051] The other side of the sliding plate 53 is fixedly provided with a first clamping table 54, and the L-shaped seat 51 is fixedly provided with a second clamping table 55 opposite to the first clamping table 54.

[0052] In this embodiment, the rotation of the first connecting rod 73 drives the second connecting rod 74 to push the sliding plate 53 to slide upward along the limiting sliding groove 52, and then drives the first clamping table 54 to move upward synchronously, so that the distance between the first clamping table 54 and the second clamping table 55 gradually decreases, until the two clamping tables are opposite to each other and clamp the outer wall of the cable. During the process, the clamping surfaces of the first clamping table 54 and the second clamping table 55 are provided with anti-skid tooth patterns, which effectively enhance the friction and prevent the cable from slipping off.

[0053] Optionally, the first guide plate 6 is fixedly arranged on the support 2 opposite to the first clamping table 54, and the second guide plate 56 is fixedly arranged on the two groups of L-shaped seats 51 opposite to the second clamping table 55. The first guide plate 6 and the second guide plate 56 are symmetrically arranged and located on the two sides of the cable entering direction respectively, for guiding the cable to accurately enter the clamping area of the first clamping table 54 and the second clamping table 55.

[0054] Optionally, the linkage assembly further comprises a ratchet assembly 712 arranged on the support 2 close to the driving assembly, the output shaft of the ratchet assembly 712 is connected with the lead screw 71, and the second gear 710 is arranged on the input shaft.

[0055] In this embodiment, through the one-way transmission characteristic of the ratchet assembly 712, it is ensured that the lead screw 71 can normally transmit power when it rotates in the positive direction under the action of the driving assembly, and it is automatically locked in the reverse direction, so as to prevent the clamping from loosening due to external disturbance. The second gear 710 is engaged with the output gear of the driving source, so as to realize efficient transmission of torque. The introduction of the ratchet assembly 712 further improves the reliability and safety of the clamping process, especially effectively maintains the stability of the clamping force in the vibration environment, avoids the cable from loosening and falling off, and ensures the continuous and safe operation of the equipment.

[0056] Optionally, the driving assembly includes a motor 711 fixedly arranged on the loading base plate 1, and the output end of the motor 711 is provided with a first gear 79. After the bracket 2 is installed on the loading base plate 1, it is necessary to confirm that the first gear 79 is correctly engaged with the second gear 710 of the ratchet assembly 712, so as to ensure stable and reliable power transmission. After the motor 711 is started, the first gear 79 drives the second gear 710 to rotate, which is transmitted to the lead screw 71 through the ratchet assembly 712, so as to realize automatic control of the clamping action.

[0057] Conversely, when the bracket 2 is separated from the loading base plate 1, the second gear 710 is disengaged from the first gear 79, the power transmission is interrupted, the lead screw 71 is locked by the ratchet assembly 712 to keep the current position, and the clamping state is ensured not to be released due to disassembly, thereby improving the safety and operation convenience of the device during maintenance or replacement. The structure design realizes self-locking of the clamping state, and even in the case of power failure or disassembly, the reliable clamping of the cable can be maintained.

[0058] Optionally, a positioning groove 9 is fixedly arranged on the loading base plate 1 corresponding to the leg portion of the bracket 2. The bracket 2 is first positioned and matched with the loading base plate 1 through the positioning groove 9, and then the limiting pull rope 76 on the loading base plate 1 is hooked on the sliding rod 78, so as to complete the quick locking and limiting of the bracket 2.

[0059] Optionally, the bracket 2 is provided with a triangular assembly 3 on both sides. By arranging the triangular assembly 3, the structural stability of the bracket 2 is enhanced, the stress is effectively dispersed, and deformation or damage caused by local stress concentration is avoided. The triangular assembly 3, the bracket 2 and the loading base plate 1 form a stable mechanical support system, which can maintain the rigidity and reliability of the overall structure under the condition of equipment operation or external vibration environment.
