Description

Technical Field

[0001] The present invention relates to the technical field of electric wire detection, and in particular to an ice-covered state detection device for a power transmission line. Background Art

[0002] Transmission lines are transmission lines for AC or DC power that people need to use in their lives. AC and DC power are transmitted to various areas through transmission lines. In rainy and snowy weather with low temperatures, ice will form on the surface of the wires, greatly increasing the load of the wires. When the load is too large, the wires will break, affecting the normal operation of power transmission. In severe cases, it will also cause major accidents such as short circuits, insulator flashovers, and tower collapses. Therefore, timely detection of the ice thickness of the transmission lines can timely detect the ice thickness and eliminate safety hazards.

[0003] At present, the commonly used methods are to directly observe the icing conditions of transmission lines manually or use drones to take pictures. For example, when inspecting lines in some mountainous areas, personnel are required to patrol the transmission lines along the mountain roads, which is not only labor-intensive but also dangerous. When using drones to take pictures, the thickness of the ice cannot be accurately detected, the detection results have large deviations, and the ice layer cannot be removed in time. When high-altitude cameras are set up near the lines for real-time monitoring, the cameras will be interrupted or damaged in extreme weather, the monitoring accuracy and stability are poor, and they are greatly affected by the environment.

DETAILED DESCRIPTION

[0036] Refer to the following Figures 1 to 13 The embodiments of the present invention are described in detail. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0037] A transmission line icing status detection device, such as Figure 1 , Figure 2 , Figure 6 , Figure 8, as shown, it includes a first walking frame 1 and a second walking frame 2, the first walking frame 1 and the second walking frame 2 are U-shaped structures, and the openings are arranged upwards, and the left and right sides of the bottom ends of the first walking frame 1 and the second walking frame 2 are respectively fixedly installed with stabilizing shafts 3, and the stabilizing shafts 3 provide support. There is a certain distance between the first walking frame 1 and the second walking frame 2, which is convenient for the installation of subsequent components. Disassembly plates 4 are respectively detachably installed on the two top ends of the second walking frame 2, and external rollers 5 are respectively installed between the two disassembly plates 4 and the top end of the first walking frame 1, and the external rollers 5 are always rotatably installed on the two top ends of the first walking frame 1, and a telescopic rod 6 is arranged between the lower ends of the first walking frame 1 and the second walking frame 2, and the telescopic rod 6 is preferably an electric telescopic rod, and a battery and a controller 19 are fixedly installed on the bottom end of the fixed plate 22, and the telescopic rod 6 connects the battery and the controller 19;

[0038] The telescopic rod 6 is arranged near the right side of the first walking frame 1 and the second walking frame 2. A lifting device is arranged at the upper end of the telescopic rod 6. A fixed shell 7 is fixedly installed on the lifting device. A cavity is arranged at the upper end of the fixed shell 7. A driving gear 8 is rotatably installed in the middle of the cavity of the fixed shell 7. Driving racks 9 are slidably installed on the left and right side surfaces of the cavity of the fixed shell 7, respectively. Two driving racks 9 are meshed and connected with the driving gear 8. A closed cover plate 10 is fixedly installed on the top of the fixed shell 7. The closed cover plate 10 is arranged above the driving rack 9 and the driving gear 8. The left and right sides of the closed cover plate 10 are respectively provided with sliding grooves 11, and the sliding grooves 11 are arranged corresponding to the driving racks 9 below. The top ends of the two driving racks 9 are respectively fixed with bent indicator rods 12, and the indicator rods 12 can slide freely back and forth in the corresponding sliding grooves 11. The top end of the closed cover plate 10 is provided with scale lines 13, and the scale lines 13 are arranged between the two indicator rods 12. A searchlight device is arranged above the fixed shell 7, and the outer ends of the two driving racks 9 are respectively fixed with upwardly extending bent rods 14;

[0039] When inspecting the ice-covered surface of the line, the personnel remove the two disassembly plates 4, use the corresponding tools to move the first walking frame 1 and the second walking frame 2 to the vicinity of the wire 61, and then pass the wire 61 through the gap between the second walking frame 2 and the external roller 5, and then place the two external rollers 5 on the top of the wire 61. At this time, the first walking frame 1 and the second walking frame 2 are suspended, and the wire 61 is placed in the groove of the external roller 5. Since the entire device has a certain weight, the center of gravity of the device will always be downward to maintain overall stability. Then, the upper end of the disassembly plate 4 is sleeved on the corresponding external roller 5 shaft, and the lower end of the disassembly plate 4 is installed on the top of the second walking frame 2 below. The controller 19 then starts the telescopic rod 6, which pushes the lifting device and the fixed shell 7 to move upward, and the top ends of the two bending rods 14 first contact the lower circular surface of the ice-covered wire 61. When the telescopic rod 6 continues to move upward, the top ends of the two bending rods 14 will continue to slide upward along the outer side of the ice, thereby opening the two bending rods 14. The two driving racks 9 will rotate with the driving gear 8 during the synchronous outward movement, and the two indicator rods 12 will move synchronously outward along the sliding groove 11. The personnel will stop working after extending the telescopic rod 6 to a certain length according to the ice-covered condition of the wire 61. At this time, the clamping diameter of the ice-covered layer of the wire 61 by the two bending rods 14 is the largest.

[0040] Then the personnel controls the corresponding device to drive the external roller 5 to move along the ice surface. Since the ice-covered surface of the wire 61 is irregular in shape, the trajectory of the bending rod 14 is also wavy. At this time, the two bending rods 14 will walk close to the ice-covered surface. At the same time, the searchlight device irradiates the trajectory of the scale line 13 pointed to by the indicator rod 12, and then feeds back the irradiation situation to the controller 19. The controller 19 calculates the average value of the ice-covered surface, and then transmits the average value to the display on the ground. The personnel can observe the thickness of the ice-covered surface of the test wire 61 through the display, and can also obtain the thickness of the ice layer of other wires 61. The personnel do not need to test the ice thickness of other lines, and can obtain more accurate ice thickness of multiple lines. This not only reduces the work intensity of the personnel, but also improves safety. Compared with manual observation or drone photography, the device has more accurate and convenient detection results, and the device can be removed in time after detection, reducing the risk of damage to the device.

[0041] When the device needs to be removed, the personnel remove the two disassembly plates 4, remove the device from the wires 61, and then clean the device.

[0042] like Figure 2 , Figure 6 , Figure 8As shown, the top ends of the two bending rods 14 are respectively fixedly mounted with contact plates 15, and the top ends of the contact plates 15 are fixedly connected with inclined plates inclined outward. Since the two inclined plates are inclined, the ice surface can smoothly enter between the two contact plates 15. The searchlight device includes a U-shaped frame 16, which is fixedly mounted on the top end of the fixed shell 7, and the closed cover plate 10 is arranged between the openings of the U-shaped frame 16. A horizontal plate 17 in the front-rear direction is fixedly mounted on the top end of the U-shaped frame 16, and a camera is fixedly mounted on the bottom end of the horizontal plate 17. 18, the controller 19 is fixedly mounted on the top of the horizontal plate 17, the camera 18 is connected to the controller 19, the controller 19 is connected to the battery, the two bending rods 14 are respectively fixedly mounted with pointers 20, the pointers 20 are arranged close to the scale line 13, the fixed shell 7 is fixedly provided with a protective cover 21, the U-shaped frame 16, the horizontal plate 17, the camera 18, the controller 19 and the pointer 20 are all arranged inside the protective cover 21, and the protective cover 21 can protect the corresponding components, prevent ice cubes from falling and damaging the components, and improve safety;

[0043] When the telescopic rod 6 continues to move upward, the two inclined plates first contact the ice surface, and the ice surface slides along the inclined surface of the inclined plate to between the two contact plates 15. The two contact plates 15 can clamp the ice surface. When the external roller 5 moves along the direction of the ice surface, the camera 18 illuminates the scale line 13 pointed by the pointer 20 in real time, and feeds back the illumination situation to the controller 19. The controller 19 calculates the average value of the detected ice surface, and then transmits the average value to the display on the ground. The personnel can observe the thickness of the ice surface of the wire 61 through the display, which improves the accuracy of the detection result and allows the personnel to understand the ice condition of the wire 61 in time.

[0044] like Figure 2 , Figure 5 As shown, a fixed plate 22 is fixedly installed between the lower ends of the first walking frame 1 and the second walking frame 2, and the fixed plate 22 is arranged just below the telescopic rod 6. The bottom end of the telescopic rod 6 is fixedly installed on the fixed plate 22. The lifting device includes two lifting plates 23. The two lifting plates 23 are respectively provided with sliding cavities 24. Push plates 25 are installed inside the two sliding cavities 24 so as to slide up and down. Two push springs 26 are respectively fixedly installed on the front and rear top ends of the push plates 25. The other end of the push spring 26 is fixedly installed on the top end of the corresponding sliding cavity 24. The fixed shell 7 is fixedly installed between the top ends of the two lifting plates 23.

[0045] like Figure 5As shown, two movable frames 27 are arranged on the top of the fixed plate 22, and the opening of the movable frame 27 is arranged downward, and an isolation plate 28 is fixedly installed between the tops of the two movable frames 27, and a circular opening is opened on the isolation plate 28, and the telescopic rod 6 is arranged in the circular opening, and the lifting plate 23 is fixedly installed on the front and rear sides of the top of the isolation plate 28, respectively, and compression blocks 29 are fixedly installed on the bottom ends of the two movable frames 27, respectively, and the bottom end of each compression block 29 is fixedly installed on the fixed plate 22, and the compression block 29 has the characteristics of tension and compression.

[0046] like Figure 3 , Figure 8 As shown, the lower ends of the two disassembly plates 4 are connected to the top of the second walking frame 2 by bolts 30, the top of the disassembly plate 4 is sleeved on the rear end rotating shaft of the corresponding external roller 5, and the bolts 30 connect the disassembly plate 4 and the top of the second walking frame 2 together, and the inner ends of the two driving racks 9 are respectively fixedly installed with tension springs 31, and the other ends of the two tension springs 31 are respectively fixedly installed with limiting blocks 32, and the limiting blocks 32 are fixedly installed on the fixed shell 7;

[0047] When the telescopic rod 6 continues to move upward, the two inclined plates first contact the ice surface, and then the ice surface slides along the inclined surface of the inclined plate to between the two contact plates 15. The ice surface on the wire 61 stretches the two contact plates 15, and the two driving racks 9 move synchronously outward, which will drive the driving gear 8 to rotate. The two indicator rods 12 move synchronously outward along the sliding groove 11. Due to the contraction force of the tension spring 31, the two contact plates 15 always clamp the ice surface. When the device moves along the wire 61, the two contact plates 15 are always in close contact with the ice surface, so the tested ice thickness is more accurate.

[0048] like Figure 3 , Figure 4 , Figure 5 , Fig.13As shown, inclined blocks 33 are fixedly installed on both ends of the two lifting plates 23, and a certain angle is formed between the inclined blocks 33 and the lifting plates 23. Internal rollers 34 are rotatably installed between the two inclined blocks 33 on the left and between the two inclined blocks 33 on the right. The two internal rollers 34 are on the same plane and are arranged below the two external rollers 5. The two external rollers 5 are also on the same plane. A groove is arranged in the middle of the internal rollers 34. A first sprocket group 35 is installed between the front sides of the two internal rollers 34. The first sprocket group 35 includes two first sprockets and a first chain. The first sprockets are coaxially fixedly installed on the front end rotating shafts of the two internal rollers 34. The two first sprockets are connected by a first chain, and the first chain is arranged on the rear side of the front bending rod 14. A motor 36 is fixedly installed on the top of the isolation plate 28, and the motor 36 is connected to the controller 19. A second sprocket group 37 is installed between the motor 36 and one of the inner rollers 34. The second sprocket group 37 includes two second sprockets and a second chain. The second sprockets are coaxially fixedly installed on the rotating shaft of the inner roller 34 on the left and the rotating shaft of the motor 36, respectively. The two second sprockets are connected by a second chain. A first gear 38 is coaxially fixedly installed on the inner roller 34 on the right, and a second gear 39 is coaxially fixedly installed on the outer roller 5 on the right.

[0049] When the telescopic rod 6 pushes the push plate 25 to move upward, the two push springs 26 push the lifting plate 23 and move the moving frame 27 and the isolation plate 28 synchronously, and the compression block 29 is stretched until the two contact plates 15 clamp the ice surface. At the same time, the grooves of the two inner rollers 34 contact the outer end ice surface of the wire 61. Due to the rebound thrust of the push spring 26, the inner roller 34 and the outer roller 5 located in the same direction can be in close contact with the outer end surface of the wire 61, and the first gear 38 and the second gear 39 are in meshing state;

[0050] The controller 19 starts the motor 36, the second sprocket set 37 and the first sprocket set 35 rotate synchronously, the first gear 38 meshes with the second gear 39 to rotate, and the inner roller 34 and the outer roller 5 roll along the ice surface, so as to test the ice thickness, monitor the line ice coverage in real time, discover and warn in time, effectively reduce line failures and accidents caused by ice coverage, ensure the safe operation of the power grid, and reduce the frequency of manual inspections; due to the rebound force of the push spring 26, the outer roller 5 and the inner roller 34 are always in contact with the ice surface to avoid slipping during rolling; the setting of the mobile frame 27 can provide a guiding effect for the telescopic rod 6 and the inner roller 34;

[0051] When the device needs to be removed, the controller 19 starts the telescopic rod 6 to retract to a certain extent and then stops, the motor 36 stops working, the two inner rollers 34 gradually move away from the outer roller 5, the first gear 38 and the second gear 39 are no longer in mesh, and the device can be removed.

[0052] like Figure 2 , Figure 7 , Fig. 9 As shown, a guide cross bar 40 is installed in the opening of the first walking frame 1 for sliding up and down, and a guide cross bar 40 is installed in the opening of the second walking frame 2 for sliding up and down, a circular synchronization frame 41 is fixedly installed between the left ends of the two guide cross bars 40, and vertical support plates 42 are fixedly installed on the left and right ends of the top side of the synchronization frame 41, and semicircular frames 43 are fixedly installed on the top ends of the two support plates 42. The outer side surface of the semicircular frame 43 is a cavity structure, and a connecting rod 44 is fixedly installed between the two semicircular frames 43. First vibration rods 45 are slidably installed on the front and rear sides of the upper ends of the two semicircular frames 43, and the first vibration rod 45 can slide freely back and forth on the semicircular frames 43, and second vibration rods 46 are installed on the bottom ends of the two semicircular frames 43 for sliding up and down, respectively. The first vibration rod 45 and the second vibration rod 46 penetrate the interior of the semicircular frames 43 when sliding.

[0053] like Figure 2 , Figure 7 , Fig. 9 As shown, a first linkage rod 47 is fixedly installed between the outer ends of the two first vibration rods 45 on the front side and between the outer ends of the two first vibration rods 45 on the rear side, a second linkage rod 48 is fixedly installed between the bottom ends of the two second vibration rods 46, and a driving link 49 is rotatably installed on the two first linkage rods 47, and the driving link 49 is arranged between the two semicircular frames 43. The lower ends of the two driving links 49 are rotatably installed on the driving square rod 50, and the bottom end of the driving square rod 50 is fixedly installed on the second linkage rod 48. Reset springs 51 are respectively sleeved on the two second vibration rods 46, and the top end of the reset spring 51 is fixedly installed on the inner end of the semicircular frame 43, and the bottom end is fixedly installed on the outer end of the semicircular frame 43. The guide cross bar 40 and the moving frame 27 on the same side are fixedly connected by screws 60.

[0054] When the telescopic rod 6 pushes the push plate 25 to move upward, the two push springs 26 push the lifting plate 23 and bring the two moving frames 27 and the guide cross bar 40 up synchronously until the inner roller 34 and the outer roller 5 are in close contact with the outer end surface of the wire 61;

[0055] At the same time, the wire 61 is just located inside the two semicircular frames 43, and the second linkage rod 48 is quickly pushed upward, and the two second vibration rods 46 hit the ice surface at the lower end of the wire 61, causing cracks or breaks on the ice surface at the lower end, and the reset spring 51 is compressed. At the same time, the driving square rod 50 drives the two first linkage rods 47 away from each other through the two driving connecting rods 49, and the first vibration rod 45 is out of contact with the ice surface;

[0056] The second linkage rod 48 is released. Due to the rebound force of the return spring 51, the second vibration rod 46 quickly slides downward and leaves the ice surface at the lower end. At the same time, the two first vibration rods 45 quickly impact the ice surfaces on the front and rear end surfaces of the wire 61, driving the square rod 50, driving the connecting rod 49, and the first linkage rod 47 to gradually return to the initial state. Since the ice surface at the lower end of the wire 61 has been cracked, the ice surface before and after the wire 61 will fall off quickly and fall to the ground when it is hit. In this way, the thickness of the ice layer is measured while the ice layer is de-iced, which helps to ensure the stability and safety of the power supply, reduce economic losses, and improve the efficiency and safety of power grid maintenance, and ensure the normal electricity demand of residents and enterprises.

[0057] like Figure 7 , Fig. 9 , Fig.10 As shown, a convex rod 52 is fixedly installed on the bottom end of the second linkage rod 48, and a top plate 53 is fixedly installed on the convex rod 52. A plurality of top semicircular blocks 54 are fixedly installed on the bottom end of the top plate 53. Three top semicircular blocks 54 are provided here, and the lower ends of the top semicircular blocks 54 are circular surfaces. A rack rod 55 is slidably installed left and right on the guide cross bar 40 on the front side, and a part of teeth is provided on the top end of the rack rod 55. A pressure spring 56 is fixedly installed on the rear end of the rack rod 55, and the other end of the pressure spring 56 is fixedly installed on the right end of the first walking frame 1. A sector gear 57 is coaxially fixedly installed on the rotating shaft of the motor 36. An L-shaped frame 58 located directly below the top plate 53 is fixedly installed on the front end of the rack rod 55, and a bottom semicircular block 59 is fixedly installed on the rear side of the top end of the L-shaped frame 58. The top end of the bottom semicircular block 59 is a circular surface, and the motor 36 can also select a forward and reverse motor;

[0058] When the motor 36 rotates with the fan-shaped gear 57, the pressure spring 56 is continuously compressed, the fan-shaped gear 57 meshes with the rack rod 55 sliding to the right, the circular surface of the bottom semicircular block 59 contacts the circular surface of the top semicircular block 54, and the bottom semicircular block 59 will quickly push up the top semicircular block 54, the top plate 53 and the protruding rod 52 push the second linkage rod 48 to move upward, the two second vibration rods 46 hit the ice surface at the lower end of the wire 61, causing the ice surface at the lower end to crack or break, the reset spring 51 is compressed, and at the same time the driving square rod 50 drives the two first linkage rods 47 away from each other through the two driving connecting rods 49, and the first vibration rod 45 is out of contact with the ice surface;

[0059] When the bottom semicircular block 59 moves to the cavity between the two top semicircular blocks 54, due to the rebound force of the return spring 51, the second vibration rod 46 quickly slides downward and leaves the lower end ice surface, and at the same time, the two first vibration rods 45 hit the front and rear ice surfaces of the wire 61, and the ice layer on the wire 61 will fall off quickly;

[0060] When the sector gear 57 is disengaged from the teeth of the rack rod 55, due to the rebound force of the pressure spring 56, the rack rod 55 quickly slides to the left, the circular surface of the bottom semicircular block 59 contacts the circular surface of the top semicircular block 54, and the bottom semicircular block 59 quickly pushes the top semicircular block 54 upward, the top plate 53 and the protruding rod 52 push the second linkage rod 48 to move upward, the two second vibration rods 46 hit the ice surface at the lower end of the wire 61, causing cracks or breaks on the ice surface at the lower end, the reset spring 51 is compressed, and at the same time, the driving square rod 50 drives the two first linkage rods 47 away from each other through the two driving connecting rods 49, and the first vibration rod 45 is out of contact with the ice surface;

[0061] When the bottom semicircular block 59 moves to the cavity between the two top semicircular blocks 54, due to the rebound force of the return spring 51, the second vibration rod 46 slides downward quickly to break away from the ice surface at the lower end, and at the same time, the two first vibration rods 45 collide with the ice surfaces on the front and rear end surfaces of the wire 61, driving the square rod 50, the driving connecting rod 49, and the first linkage rod 47 to return to the initial state. Since the ice surface at the lower end of the wire 61 has been cracked, the ice layer on the wire 61 will fall off quickly when the ice surfaces at both ends are hit, which helps to ensure the stability and safety of the power supply, and also realizes the walking and ice layer work of the device. Since the bottom semicircular block 59 continuously moves back and forth up and down against the top semicircular block 54, the deicing efficiency is improved and the dual function is realized.
