The connecting rod 41 is symmetrically arranged, and both ends are fixedly connected to the upper end between the symmetrical vertical plates 2. The other two ends of the connecting rod 41 are fixedly connected with a mounting plate 42. The mounting plate 42 is provided with a plurality of linearly distributed placement grooves. The blocks 47 are fixedly arranged at the rear end of the placement groove. The push rods 45 are movable and pass through the middle of the block 47. There are two laser displacement ranging sensors 48 that are symmetrically arranged at the upper end of the side wall of the mounting plate 42 corresponding to the push rod 45; the rod body of the connecting rod 41 is also provided with a limiting mechanism 5 and a de-icing component 6 that cooperate with each other.

[0028] The thickness detection mechanism 4 also includes a top ball 43, a connecting block 44, a return spring 46 and a scale 49. The return spring 46 is sleeved on the outer wall of the push rod 45, and the two ends of the return spring 46 are fixedly connected to the connecting block 44 and the clamping block 47 respectively. One end of the push rod 45 is fixedly connected to one end face of the connecting block 44, and the other end face of the connecting block 44 is fixedly connected to the top ball 43. The scale 49 is provided on the upper end of one side wall of the mounting plate 42, and the push rod 45 can be pushed to the laser displacement ranging sensor 48 as the return spring 46 is compressed. Below; by setting the ice thickness of the conductor line, the top ball 43 is squeezed, and the squeezing of the top ball 43 drives the connecting block 44 to move into the placement groove opened on the mounting plate 42, thereby driving the push rod 45 to move on the block 47, and then the end of the push rod 45 will continue to move and extend to the bottom of the laser displacement ranging sensor 48, and the laser displacement ranging sensor 48 is turned on to measure the distance length of the push rod 45 extending to the laser displacement ranging sensor 48, thereby measuring the ice thickness of the conductor line. The operation is relatively simple and practical.

[0029] The conveying mechanism 3 also includes a conveying motor 31, a first pulley 32, a first belt 33 and a second belt 37. The conveying motor 31 is fixedly arranged at the top position of the base 1 on one side of one of the vertical plates 2.

The first belt 33 is rotatably connected to the two first pulleys 32, and the second belt 37 is rotatably connected to the symmetrical second pulley 36.

[0030] The limiting mechanism 5 includes a mounting frame 51, a stepper motor 52 and a screw 53. The mounting frame 51 is fixedly connected to one side of the top of the connecting rod 41. The stepper motor 52 is fixedly arranged in the middle position of the top of the mounting frame 51. The output shaft of the stepper motor 52 movably passes through the mounting frame 51 and is coaxially connected to the end of the screw 53. The other end of the screw 53 is rotatably connected to the bottom of the mounting frame 51.

[0031] Furthermore, the limiting mechanism 5 also includes a movable block 54, a guide rod 55 and a limiting block 56, the movable block 54 is threadedly arranged on the outer wall of the screw 53, the guide rod 55 is symmetrically arranged at the bottom of the movable block 54, and the other end of the guide rod 55 is movable through the bottom of the installation frame 51 and connected to the limiting block 56, and the de-icing component 6 is located below the limiting block (56); by setting the output shaft of the stepping motor 52 to drive the screw 53 to rotate, the rotation of the screw 53 drives the movable block 54 to move downward, thereby driving the symmetrical guide rod 55 to move downward, and then driving the limiting block 56 to move downward, pressing the upper end of the wire line to the working area of the de-icing component 6 below to prevent its sliding displacement from having an adverse effect on subsequent de-icing, and ensuring that the de-icing work can be fully performed.

[0032] The de-icing assembly 6 includes a connecting plate 61, a second rotating shaft 62, a third pulley 63, a third belt 64 and a de-icing thorn cylinder 65. The connecting plates 61 are symmetrically fixed on both sides of the connecting rod 41 below the mounting frame 51. The second rotating shaft 62 is arranged between the symmetrical connecting plates 61 and movably passes through the connecting plates 61. The third pulley 63 is fixedly connected to the end of the second rotating shaft 62. The third belt 64 is rotatably connected to the third pulley 63 and one of the second pulleys 36. The de-icing thorn cylinder 65 is fixedly connected to the outer wall of the second rotating shaft 62 and is located between the symmetrical connecting plates 61. By setting the second pulley 36 to drive the third belt 64 to rotate, the third pulley 63 is driven to rotate, and then the de-icing thorn cylinder 65 on the second rotating shaft 62 is driven to rotate, so as to rotate and de-ice the wire line, thereby avoiding trouble in subsequent use and causing line damage and failure.

[0033] The working principle of this utility model is roughly as follows:

[0034] When in use, the staff first places the wire line to be inspected onto the conveying roller 35, then starts the conveying motor 31 output shaft to drive the first pulley 32 to rotate, thereby driving the first belt 33 to rotate, and the rotation of the first belt 33 drives the other first pulley 32 to rotate, thereby driving the conveying roller 35 to rotate, and conveying the wire to the other conveying roller 35. When the wire line passes through the mounting plate 42 on the connecting rod 41, the wire line will produce ice layers of varying thicknesses after being covered with ice, thereby squeezing the top ball 43. The squeezing of the top ball 43 drives the connecting block 44 to move into the placement groove opened on the mounting plate 42, thereby driving the pushing rod 45 to move on the card block 47, and then the end of the pushing rod 45 will continue to move and extend to the bottom of the laser displacement ranging sensor 48. The laser displacement ranging sensor 48 is turned on to measure the distance length from the pushing rod 45 to the laser displacement ranging sensor 48, thereby measuring the ice thickness of the wire line. The operation is relatively simple and practical.

[0035] Secondly, after the measurement is completed, the output shaft of the stepper motor 52 is started to drive the screw 53 to rotate. The rotation of the screw 53 drives the movable block 54 to move downward, thereby driving the symmetrical guide rod 55 to move downward, and then driving the limit block 56 to move downward, pressing the upper end of the wire line, and cooperating with the de-icing component 6, under the continuous driving and transportation of the conveying motor 31, the second pulley 36 drives the third belt 64 to rotate, thereby driving the third pulley 63 to rotate, and then driving the de-icing thorn barrel 65 on the second rotating shaft 62 to rotate, rotating and de-icing the wire line, avoiding troubles in subsequent use and causing line damage and failure.

[0036] As a supplement, the overall tendency of the present invention is to use a physical structure with fewer electric drive components, and to achieve the target function with reasonable linkage and structural layout. Except for the necessary driven wheel group which needs to be connected and driven by the driving stepper motor, the execution of other linkages is realized through transmission parts. Therefore, the reason why the overall structure functions is also due to the structural design itself. On the basis of satisfying the connection relationship of the present invention, for the necessary control structure and power supply structure for controlling the action of the present invention, technical personnel in this field can refer to basic electrical knowledge and combine the material conditions of the actual working environment to carry out adaptive selection and installation, so as to meet the action process and technical indicators described above of the present invention.

[0037] The laser displacement ranging sensor 48 is a type of sensor used in many occasions, and its working mechanism and control relationship are also well known to technical personnel in this field. For example, in the environment with an ambient temperature of -10℃-+40℃, Yiwei Optics' ET-S400N has a detection range of ±20 cm, which can adapt to relatively less harsh environments. With good moisture-proof protection, it can cope with ice that is not particularly thick. If the occasion is more extreme, it is sufficient to choose a sensor product with a larger measurement parameter range in accordance with industry practices.

[0038] Since the present invention is applied to the process of breaking ice in a simulated scenario, when the line is actually broken, it is necessary to adapt the ice-breaking structure to the movement of the line, such as adding reasonable counterweights or improving the stability of the connection of the equipment, adding a line movement structure, etc. For such necessary structures, those skilled in the art can refer to the operation methods of other existing equipment such as line patrol robots for setting.

Other structures can refer to common designs. In the absence of conflicts, the same embodiment and different embodiments of the present invention can be combined with each other.
