Description

Technical Field

[0001] The present invention relates to the technical field of line survey, and in particular to an ice shelf for surveying a transmission line. Background Art

[0002] my country is one of the countries with the most severe icing on power transmission lines, especially in southern China, where high altitudes, micro-topography, and micro-climates make icing disasters frequent, posing a significant challenge to the safe operation of power grids. Icing increases conductor weight and sag, potentially leading to line breakage, tower collapse, flashover, and galloping. Therefore, ice observation is crucial for preventing transmission line accidents caused by icing.

[0003] Currently, ice observation is conducted using an ice observation stand. This stand uses two towers with steel beams to connect the two ends of a wire, simulating actual wires. Artificial ice observation is currently the most accurate method, but during icing season, ice observation stands can be slippery and icy, and most of the locations where they are set up are on mountainside, making manual climbing of these stands risky.

[0004] In addition, the existing technology has the following disadvantages: when setting up an ice observation rack on a mountain with a slope, the inclination of the simulated wire will be set with reference to the slope of the mountain. Due to the weathering effect on the mountain, particles such as sand and dust will collide and erode the rock surface, causing the rock to gradually break, decompose, and become loose, resulting in collapse, landslides and other phenomena, which will cause the slope to change, and then the inclination of the simulated wire set according to the slope of the mountain will be different from the slope, thereby affecting the ice detection results.

[0005] In addition, after the ice detection within a unit time is completed, the ice on the simulated wire needs to be cleared. The risk factor of manual removal is too high, which affects the efficiency of ice detection within the next unit time.

[0006] In addition, the detection of ice coverage on the wires is generally done by setting tension sensors at both ends of the wires, measuring the weight of ice on the wires per unit length, and then converting the ice coverage. The wind on the mountain will cause the wires to pull on the tension sensors, thereby damaging the tension sensors or causing inaccurate data measured by the tension sensors, which will affect the accuracy of the ice detection data.

[0007] Therefore, it is necessary to solve the above problems through a transmission line survey and ice shelf observation. Summary of the Invention

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] In order to solve the problem that the inclination of the simulated wire 5 set according to the mountain slope is different from the slope due to natural changes in the mountain slope, the problem that the risk factor of manually removing ice on the wire is too high, and the problem that wind force causes the wire to pull the tension sensor 4, resulting in inaccurate or damaged data measured by the tension sensor 4, the following embodiments are proposed.

[0031] The present invention provides Figures 1 to 5The transmission line survey and ice observation rack shown in the figure includes a fixed support rod 1, a lifting component 2 is provided on the top of the fixed support rod 1, a connecting block 3 is provided on the top of the lifting component 2, a tension sensor 4 is provided on one side of the connecting block 3, and a guide rod 7 is provided on the other side. The measuring end of the tension sensor 4 is provided with a simulation wire 5, and the two ends of the simulation wire 5 are clamped at the measuring end of the tension sensor 4. According to the actual installation situation of the line, there will be a certain sagging arc when the simulation wire 5 is set. Therefore, when the inclination of the simulation wire 5 needs to be adjusted, the two lifting components 2 adjust the height of the two ends of the simulation wire 5 while keeping the spacing unchanged, and the simulation wire 5 will basically not be affected. A gravity component 6 is slidably provided on the guide rod 7. A monitoring platform 9 is fixedly provided on the top of the lifting component 2, and a camera 10 is provided in the monitoring platform 9. A laser rangefinder is provided on the bottom surface of the monitoring platform 9, and the laser rangefinder can measure its distance from the ground. Thereby determining whether the inclination of the current simulated conductor 5 is consistent with the slope of the mountain; it also includes a remote control center, which is connected to the lifting assembly 2, the tension sensor 4, the camera 10 and the laser rangefinder through electrical signals; the picture taken by the camera 10 is transmitted to the remote control center in real time, and the data measured by the tension sensor 4 is transmitted to the remote control center for recording through electrical signals. The staff can know the icing situation of the wires in the same environment from the data. One end of the guide rod 7 is set as a circular ring and is rotatably connected to any connecting block 3, and the other end is set as an elongated elliptical ring and is rotatably connected to another connecting block 3. The other connecting block 3 can slide in the elongated elliptical ring. The setting of the circular ring and the elongated elliptical ring makes it convenient for the simulated conductor 5 to adjust its inclination as the slope of the mountain changes, and the guide rod 7 can still play a normal guiding role; the bottom end of the fixed support rod 1 is installed on the embedded platform 12, and the embedded platform 12 is set on the mountain of the line to be surveyed.

[0032] By setting up the gravity component 6, the pulling force of the simulated wire 5 on the tension sensor 4 under the action of wind is reduced, thereby avoiding inaccurate or damaged measurement data of the tension sensor 4, and avoiding affecting the accuracy of the ice detection data; the gravity component 6 can also cooperate with the lifting component 2 to remove the ice on the simulated wire 5 after the current ice measurement is completed, avoiding manual removal, ensuring the safety of workers, and speeding up the efficiency of the next ice detection; by setting up the lifting component 2, in conjunction with the laser rangefinder, the inclination of the simulated wire 5 is adjusted, so that the inclination of the simulated wire 5 changes with the slope of the mountain, thereby ensuring the accuracy of the ice detection results.

[0033] like Figure 4As shown, the gravity assembly 6 includes a supporting cross bar 603, one end of the supporting cross bar 603 is provided with a counterweight plate 601, and a counterweight block 602 is movably installed on the side of the counterweight plate 601. The counterweight block 602 can be replaced with metal blocks of different weights as needed, and the bottom end of the counterweight plate 601 is connected to a traction ring 605; a slider 604 is provided at the end of the supporting cross bar 603 away from the counterweight plate 601, and the guide rod 7 is passed through the slider 604. The slider 604 slides back and forth along the guide rod 7, and the end of the simulated wire 5 is slidably installed in the traction ring 605. An ice breaker 606 is provided on the same side of the traction ring 605 and the slider 604. The ice breaker 606 on the traction ring 605 is used to remove ice on the guide rod 7, and the ice breaker 606 on the slider 604 is used to remove ice on the surface of the simulated wire 5.

[0034] During use, during the ice measurement phase, the weight of the counterweight 602 can effectively stabilize the swing of the simulated wire 5, slow down the swing of the simulated wire 5 under the blowing of wind, and slow down the influence of the swing of the simulated wire 5 on the tension sensor 4, thereby ensuring the accuracy of the measurement results.

[0035] During the de-icing stage, the control center starts the interception motor 801 located at a high position based on the image captured by the camera 10. The interception motor 801 drives the interception plate 803 to rotate to a horizontal state, canceling the temporary fixation of the gravity component 6. Due to its own large gravity, the gravity component 6 will move along the guide rod 7 and the simulated wire 5 to the lower end. During the movement, the ice breaker 606 cleans the ice on the surface of the guide rod 7 and the simulated wire 5, thereby completing the removal of the ice, avoiding manual removal, and ensuring the safety of workers.

[0036] like Figure 5 As shown, the lifting assembly 2 includes a lifting column 201, which is inserted into the fixed support rod 1. A gearing portion 202 is provided at the bottom of the lifting column 201, and the gearing portion 202 is meshed and connected with a driving gear 203; a protective box 11 is provided on the outside of the top of the fixed support rod 1, and the protective box 11 is sleeved on the outside of the lifting column 201. A lifting motor 204 is installed on the inner bottom of the protective box 11, and the output shaft of the lifting motor 204 is fixedly connected to the driving gear 203.

[0037] During use, the staff installs the fixed support rod 1 on the embedded platform 12 in sequence, and the remote control center starts the lifting motor 204 to rotate forward. The lifting motor 204 drives the lifting column 201 to rise through the driving gear 203 until the data detected by the laser detector reaches the distance required for installation, that is, the height of the simulated wire 5 rises to the height required to measure the ice coverage, and the rotation of the lifting motor 204 is stopped.

[0038] Under normal circumstances, in the initial stage of installation, when the slope of the mountain has not changed, the measurement data of the two laser rangefinders are basically consistent. When the measurement data of the two laser rangefinders differ, the data is transmitted to the remote control center. After receiving the data, the remote control center determines whether the data is increased or decreased compared with the initial data. If the data increases, it means that the soil layer on the surface of the mountain has been lost, resulting in an increase in the laser distance measurement and the data from the ground. At this time, the remote control center controls the lifting motor 204 to reverse, and drives the lifting column 201 to lower through the drive gear 203 until the measurement data of the laser rangefinder changes to the initial data, and stops the rotation of the lifting motor 204; if the data decreases, it means that the soil layer on the surface of the mountain has accumulated, resulting in a decrease in the laser distance measurement and the data from the ground. At this time, the remote control center controls the lifting motor 204 to rotate forward, and drives the lifting column 201 to rise through the drive gear 203 until the measurement data of the laser rangefinder changes to the initial data, and stops the rotation of the lifting motor 204.

[0039] By setting up a laser rangefinder, the distance data from the ground is regularly measured and transmitted to the remote control center. After receiving the data, the remote control center compares it with the initial data to determine whether the current mountain slope has changed. If so, the lifting component 2 is used to promptly adjust the inclination of the simulated wire 5 to keep it consistent with the mountain slope, thereby ensuring accurate ice detection results.

[0040] During the de-icing phase, the de-icing effect is monitored by camera 10, and the de-icing process is transmitted to the remote control center through camera 10 for staff to view. Since there is a downward arc in the middle of the simulated wire 5, the ice at this arc position is relatively solid and thick compared to the ice at the two ends. When the camera 10 detects that the gravity component 6 cannot complete the de-icing by its own gravity, the lifting component 2 can cooperate with the gravity component 6 to de-icing. Specifically: the lifting motor 204 in the lifting component 2 in the high position is controlled to reverse, thereby driving the lifting column 201 to lower through the drive gear 203; at the same time, the lifting motor 204 in the lifting component 2 in the low position is controlled to rotate forward, thereby driving the lifting column 201 to rise through the drive gear 203, so that the gravity component 6 can return to its initial position.

[0041] When the camera 10 captures that the gravity assembly 6 returns to its initial position along the guide rod 7, the remote control center stops the rotation of the lifting motor 204 and rotates both in the opposite direction relative to the current rotation direction, controls the two lifting motors 204 to rotate rapidly in the opposite direction, and drives the two lifting columns 201 to return to their initial positions rapidly, so that the gravity assembly 6 quickly rushes to the position where the ice is hard along the guide rod 7, and the ice breaker 606 impacts and breaks the ice. The position of the gravity assembly 6 can be adjusted by repeatedly lifting and lowering the two lifting columns 201, so that the gravity assembly 6 can generate a larger impact force to break the ice until all the ice on the surface of the simulated conductor 5 is broken.

[0042] Once all the ice on the surface of simulated conductor 5 has been broken, the remote control center raises and lowers the two lifting columns 201 to return gravity assembly 6 to its initial position. The interception motor 801 is then activated, driving interception plate 803 to a vertical position, thus restoring the temporary fixation of gravity assembly 6. The lifting motor 204 then controls the lifting columns 201 back to their initial position, returning simulated conductor 5 to an inclined position consistent with the mountain slope, ready for the next ice measurement.

[0043] By setting up a camera 10, the de-icing situation of the gravity component 6 is filmed and transmitted to the remote control center. When the remote control center detects that the gravity component 6 is blocked from breaking ice, the two lifting columns 201 are controlled to rise and fall repeatedly and quickly, driving the gravity component 6 back to the initial position, and then quickly impacting the solid ice position, so that the gravity component 6 can successfully break the ice, avoiding manual removal, ensuring the safety of the staff, and speeding up the ice detection efficiency in the next unit time.

[0044] like Figure 4 As shown, an interception component 8 is provided on the bottom surface of the monitoring platform 9, and the interception component 8 includes an interception motor 801. The interception motor 801 is installed on the bottom surface of the monitoring platform 9 through a mounting bracket 802, and the output shaft of the interception motor 801 is fixedly connected to an interception plate 803; the end of the interception plate 803 away from the interception motor 801 is set as a semicircular part, and the inner diameter of the semicircular part is consistent with the diameter of the supporting cross bar 603.

[0045] When in use, in the intercepting state, the intercepting plate 803 is in a vertical state, and the inner diameter of the semicircular part of the intercepting plate 803 fits against the outside of the supporting cross bar 603 to intercept the supporting cross bar 603; in the non-intercepting state, the intercepting plate 803 is in a horizontal state, and the intercepting plate 803 cancels the interception of the supporting cross bar 603.

[0046] The working principle of the present invention is as follows: First, the fixed ice observation rack is installed, and the staff installs the fixed support rod 1 on the embedded platform 12 in sequence. The remote control center starts the lifting motor 204 to rotate forward, and the lifting motor 204 drives the lifting column 201 to rise through the driving gear 203 until the data detected by the laser detector reaches the distance required for installation, that is, the height of the simulated wire 5 is raised to the height required to measure the ice coverage, and the rotation of the lifting motor 204 is stopped.

[0047] Secondly, the icing condition of the wires is observed. The images captured by the camera 10 are transmitted to the remote control center in real time. The tension sensor 4 detects the weight change of the simulated wire 5 in real time. The measured data is transmitted to the remote control center via electrical signals for recording. The staff can learn from the data the icing condition of the wires per unit time under the same environment.

[0048] Then, the slope change is detected and the inclination of the wire is adjusted in time. The remote control center starts the laser rangefinder at a fixed time. When the measurement data of the two laser rangefinders differ, the data is transmitted to the remote control center. After receiving the data, the remote control center determines whether the data is increased or decreased compared with the initial data. If the data increases, it means that the soil layer on the surface of the mountain has been lost, resulting in an increase in the laser distance measurement and the data from the ground. At this time, the remote control center controls the lifting motor 204 to reverse and drive the lifting column 201 to lower through the drive gear 203 until the measurement data of the laser rangefinder changes to the initial data, and stops the rotation of the lifting motor 204; if the data decreases, it means that the soil layer on the surface of the mountain has accumulated, resulting in a decrease in the laser distance measurement and the data from the ground. At this time, the remote control center controls the lifting motor 204 to rotate forward and drives the lifting column 201 to rise through the drive gear 203 until the measurement data of the laser rangefinder changes to the initial data, and stops the rotation of the lifting motor 204.

[0049] Then, the ice detection is completed and de-icing is carried out. The control center starts the interception motor 801 located at a high position based on the image captured by the camera 10. The interception motor 801 drives the interception plate 803 to rotate to a horizontal state, canceling the temporary fixation of the gravity component 6. Due to its own large gravity, the gravity component 6 will move along the guide rod 7 and the simulated wire 5 to the lower end. During the movement, the ice-breaking knife 606 cleans the ice on the surface of the guide rod 7 and the simulated wire 5, thereby completing the removal of the ice.

[0050] Then, if de-icing becomes difficult, the de-icing effort is increased. During the de-icing phase, the de-icing effect is monitored through the camera 10, and the de-icing process is transmitted to the remote control center through the camera 10 for the staff to view. When the camera 10 detects that the gravity assembly 6 is unable to complete de-icing by its own gravity, the lifting assembly 2 can cooperate with the gravity assembly 6 to de-icing. Specifically, the lifting motor 204 in the lifting assembly 2 in the high position is controlled to reverse, thereby driving the lifting column 201 to lower through the drive gear 203; at the same time, the lifting motor 204 in the lifting assembly 2 in the low position is controlled to rotate forward, thereby driving the lifting column 201 to rise through the drive gear 203, so that the gravity assembly 6 can return to its initial position. When the camera 10 captures that the gravity assembly 6 returns to its initial position along the guide rod 7, the remote control center stops the rotation of the lifting motor 204 and rotates both in the opposite direction relative to the current rotation direction, controls the two lifting motors 204 to rotate rapidly in the opposite direction, and drives the two lifting columns 201 to return to their initial positions rapidly, so that the gravity assembly 6 quickly rushes to the position where the ice is hard along the guide rod 7, and the ice breaker 606 impacts and breaks the ice. The position of the gravity assembly 6 can be adjusted by repeatedly lifting and lowering the two lifting columns 201, so that the gravity assembly 6 can generate a larger impact force to break the ice until all the ice on the surface of the simulated conductor 5 is broken.

[0051] Finally, the inclination of the simulated wire 5 is restored. Once all the ice covering the surface of the simulated wire 5 has been broken, the remote control center raises and lowers the two lifting columns 201 to return the gravity assembly 6 to its initial position. The interception motor 801 is then activated, driving the interception plate 803 to a vertical position, thus restoring the temporary fixation of the gravity assembly 6. The remote control center then controls the lifting columns 201 via the lifting motor 204 to return them to their initial positions, restoring the simulated wire 5 to its inclination consistent with the mountain slope. The system is then ready for the next ice measurement.

[0052] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
