Description

Technical Field

[0001] The present invention relates to a patrol inspection, and in particular to an intelligent patrol inspection system for power transmission lines, which is applied in the technical field of power transmission line patrol inspection. Background Art

[0002] Transmission line inspection is an important part of ensuring the stable operation of the power system and timely discovering potential faults. Traditional inspection methods mainly rely on manual inspections, but with the advancement of technology, automated technologies such as drone inspections and robot inspections have gradually emerged, greatly improving inspection efficiency. Inspectors can choose appropriate inspection methods based on factors such as on-site conditions.

[0003] The invention patent with publication number CN102136162B discloses a power transmission line inspection system. The system integrates advanced GPS and handheld computer technology, adopts component GIS technology and introduces embedded GIS ideas to realize power transmission line inspection. The system positioning is relatively accurate and the defect data collection is complete. In addition to being used for power system line inspection such as power transmission and distribution, it can also be widely used in the management of outdoor entities related to inspection such as telecommunications, coal gas and natural gas, effectively reducing operating costs and improving economic benefits.

[0004] The invention patent with publication number CN106300139B discloses a transmission line inspection device and a transmission line inspection system. The transmission line inspection device in the invention can be applied to transmission line monitoring in various environments, and the transmission line inspection system can perform comprehensive inspections, greatly improving the working efficiency of the entire transmission line.

[0005] Transmission line inspections are generally carried out regularly, but when encountering some severe weather, such as heavy snow, excessive snow accumulation may cause damage to the conductors. Therefore, after heavy snow, even if the scheduled inspection cycle has not arrived, the inspectors may conduct special inspections on the transmission lines. However, in the existing technology, the inspectors can only roughly judge whether inspections are needed based on the snowfall announced by the meteorological department (or the snowfall obtained through other means). This may not only lead to unnecessary inspections, resulting in a waste of manpower and resources, but may also lead to missed inspections (that is, inspections that should be carried out are not carried out), which may easily lead to failure to timely discover abnormalities in the transmission lines, and thus easily affect the stable operation of the power system. Therefore, we propose an intelligent inspection system for transmission lines. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is: in heavy snow weather, inspection personnel can only roughly judge whether it is necessary to inspect the transmission lines based on the amount of snowfall, which may not only lead to unnecessary inspections and waste of manpower and resources, but also may lead to missed inspections.

[0007] In order to solve the above problems, the present invention provides an intelligent inspection system for power transmission lines, including an inspection control center and multiple inspection and judgment assistance mechanisms. The inspection control center includes a threshold setting module, an inspection start control module, and an inspection reminder module; The detection and judgment assistance mechanism includes a supporting base fixedly connected to the pole tower in the transmission line, the supporting base is provided with a detection assembly and a detection and judgment terminal, the detection assembly includes a sealing cylinder fixedly installed on the supporting base, a piston plate is provided in the sealing cylinder and is slidably and sealably connected thereto, a pair of elastic suspension ropes are fixedly connected between the piston plate and the top inner wall of the sealing cylinder, a connecting slide rod is fixedly connected to the top of the piston plate, the connecting slide rod passes through the top outer wall of the sealing cylinder and is slidably and sealably connected thereto, an accumulation detection rod body is fixedly connected to the top of the connecting slide rod, the diameter of the accumulation detection rod body is the same as the diameter of the conductor in the transmission line, and the accumulation detection rod body and the conductor are at the same height, and a distance sensor is fixedly installed on the bottom inner wall of the sealing cylinder; The inspection and control terminal is provided with an inspection and control module and an analysis and judgment module. The threshold setting module is connected to the analysis and judgment module by signal, the inspection start control module is connected to the inspection and control module by signal, the inspection and control module is connected to the distance sensor by signal, the distance sensor is connected to the analysis and judgment module by signal, and the analysis and judgment module is connected to the patrol reminder module by signal.

[0008] In the above-mentioned intelligent inspection system for transmission lines, the detection and judgment assistance mechanism can, under the control of the inspection and control center, truly and reliably detect the amount of snow accumulation and determine whether the amount of snow accumulation is within the bearing range of the conductor, thereby providing a more real and reliable basis for determining whether it is necessary to inspect the transmission lines.

[0009] As a further improvement of the present application, a distance threshold is reasonably set through the threshold setting module to determine whether the amount of snow accumulation has exceeded the bearing range of the wire. In snowy weather, the detection control module sends a detection instruction to the detection and accumulation control module. After receiving the detection instruction, the detection and accumulation control module will start the distance sensor to enable the distance sensor to detect the distance between it and the piston plate, and the distance data detected by the distance sensor will be transmitted to the analysis and judgment module, so that the analysis and judgment module can determine whether the amount of snow accumulation has exceeded the bearing range of the wire by comparing the distance data and the distance threshold. When the judgment result of the analysis and judgment module is that the amount of snow accumulation has exceeded the bearing range of the wire, the analysis and judgment module will send an instruction to the patrol reminder module to enable the patrol reminder module to emit an alarm sound representing danger. When the judgment result of the analysis and judgment module is that the amount of snow accumulation has not exceeded the bearing range of the wire, the analysis and judgment module will send an instruction to the patrol reminder module to enable the patrol reminder module to emit a prompt sound representing safety.

[0010] As a further improvement of the present application, the patrol inspection and control center also includes a visualization display module, and a patrol assistance positioning module is also provided in the inspection and control terminal. Both the analysis and judgment module and the patrol assistance positioning module are signal-connected to the visualization module, and the analysis and judgment module is signal-connected to the patrol assistance positioning module, which can improve the reliability and practicality of the system.

[0011] As a further improvement of the present application, the snow accumulation detection rod body is composed of a supporting inner rod and a matching wire outer sleeve fixedly mounted on the supporting inner rod. The material of the matching wire outer sleeve is the same as the material of the outermost layer of the conductor, so that the snow accumulation conditions on the snow accumulation detection rod body can more realistically and accurately reflect the snow accumulation conditions on the conductor.

[0012] As a further improvement of the present application, a fixed plate electric push rod is fixedly installed on the inner wall of the bottom end of the sealing cylinder, and the inspection and control module is connected with the signal of the fixed plate electric push rod, so that the elastic suspension rope can maintain good elasticity without affecting the detection, thereby ensuring the accuracy of the detection.

[0013] As a further improvement of the present application, a C-shaped air duct is provided on the outer wall of the sealing cylinder, and the two ends of the air duct are respectively located on the upper and lower sides of the piston plate, and both ends of the air duct are connected to the interior of the sealing cylinder to prevent the air in the sealing cylinder from hindering the up and down movement of the piston plate, thereby facilitating the detection.

[0014] As another improvement of the present application, the number of accumulation inspection components is two, one of which is equipped with a snow removal auxiliary inspection component, which includes a support vertical plate fixedly mounted on a support base, on which an electric push rod for removing snow is fixedly mounted, and the snow removal auxiliary inspection component also includes a snow removal sleeve matching the accumulation inspection rod body, and a linkage rod is fixedly connected between the snow removal sleeve and the output end of the electric push rod for removing snow.

[0015] As another improvement supplement to the present application, the snow removal sleeve is located directly in front of the corresponding accumulation detection rod body, and the snow removal sleeve is composed of an external connecting sleeve and an annular snow removal brush fixedly installed on the inner wall of the external connecting sleeve. The external connecting sleeve and the annular snow removal brush are both arranged in a circular ring shape with a notch at the bottom, and the notch matches the connecting slide rod. The accumulation detection and control module is connected to the signal of the expulsion electric push rod, so that the amount of snow can be further detected while effectively eliminating the interference of environmental factors.

[0016] To summarize, the present application, through the joint setting of the inspection and control center and the inspection and accumulation auxiliary judgment mechanism, enables the inspection and accumulation auxiliary judgment mechanism to truly and reliably detect the amount of snow under the control of the inspection and control center, and judge whether the amount of snow is within the bearing range of the conductor, thereby providing a more real and reliable basis for judging whether it is necessary to inspect the transmission line, thereby not only avoiding the waste of manpower and resources due to unnecessary inspections to a large extent, but also avoiding the occurrence of missed inspections to a large extent; and through the setting of two inspection and accumulation components and snow removal auxiliary inspection components, the amount of snow can be further detected while effectively eliminating the interference of environmental factors, so that it can more accurately and reliably detect whether the amount of snow has exceeded the bearing range of the conductor, greatly improving the reliability of the system.

[0019] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0020] The first implementation method: Figure 1-Figure 6 An intelligent inspection system for power transmission lines is shown, including an inspection control center and multiple inspection and judgment assistance mechanisms. The inspection control center includes a threshold setting module, an inspection start control module, and an inspection reminder module; The detection and judgment assistance mechanism includes a support base 101 fixedly connected to a pole tower in a power transmission line, and an detection and judgment component 002 and an detection and judgment terminal 003 are arranged on the support base 101. The detection and judgment component 002 includes a sealing cylinder 201 fixedly installed on the support base 101, and a piston plate 202 is arranged in the sealing cylinder 201 and is slidably and sealedly connected thereto, and a pair of elastic suspension ropes 203 are fixedly connected between the piston plate 202 and the top inner wall of the sealing cylinder 201, and a connecting slide rod 204 is fixedly connected to the top of the piston plate 202, and the connecting slide rod 204 passes through the top outer wall of the sealing cylinder 201 and is slidably and sealedly connected thereto, and an accumulation detection rod body 205 is fixedly connected to the top of the connecting slide rod 204, and the diameter of the accumulation detection rod body 205 is the same as the diameter of the wire in the power transmission line, and the accumulation detection rod body 205 and the wire are at the same height, and a distance sensor 206 is fixedly installed on the bottom inner wall of the sealing cylinder 201; The inspection and control terminal 003 is provided with an inspection and control module and an analysis and judgment module. The threshold setting module is signal-connected to the analysis and judgment module, the inspection start control module is signal-connected to the inspection and control module, the inspection and control module is signal-connected to the distance sensor 206, the distance sensor 206 is signal-connected to the analysis and judgment module, and the analysis and judgment module is signal-connected to the patrol reminder module.

[0021] When arranging the detection and judgment aid mechanism, relevant technical personnel can reasonably plan the layout points of the detection and judgment aid mechanism according to factors such as the distribution of the transmission line, and then install multiple detection and judgment aid mechanisms at multiple layout points respectively. When installing the detection and judgment aid mechanism, a suitable method can be selected according to the situation, and the support base 101 can be fixedly connected to the pole tower, or the support base 101 can be directly fixedly installed at a suitable position on the pole tower, so that the accumulation detection rod body 205 is located next to the conductor and the accumulation detection rod body 205 and the conductor are at the same height, so that the accumulation detection rod body 205 and the conductor are in the same environment. When snow accumulates on the conductor due to snowfall, snow will also accumulate on the accumulation detection rod body 205 at the same time. Therefore, the amount of snow on the conductor can be detected by detecting the amount of snow on the accumulation detection rod body 205, so as to determine whether the amount of snow has exceeded the bearing range of the conductor, thereby providing a real and reliable basis for determining whether it is necessary to inspect the transmission line; The relevant technicians can set a distance threshold through the threshold setting module according to the situation to judge whether the amount of snow accumulation has exceeded the bearing range of the wire. In snowy weather, the relevant technicians can issue a detection instruction to the detection and accumulation control module through the detection control module. After receiving the detection instruction, the detection and accumulation control module will start the distance sensor 206 to make the distance sensor 206 detect the distance between it and the piston plate 202, and the distance data detected by the distance sensor 206 will be transmitted to the analysis and judgment module, so that the analysis and judgment module can judge whether the amount of snow accumulation is within the bearing range of the wire by comparing the distance data and the distance threshold. Since the snow accumulation will increase the weight of the detection rod 205, the piston plate 202 will be 02 moves downward, the more snow accumulates, the greater the distance the piston plate 202 moves downward, and the smaller the distance between the distance sensor 206 and the piston plate 202. When the distance between the distance sensor 206 and the piston plate 202 is less than the distance threshold, it means that the amount of snow is too much and has exceeded the bearing range of the wire. It is necessary to inspect the transmission line to further accurately check whether the wire is damaged due to excessive snow accumulation. On the contrary, if the distance between the distance sensor 206 and the piston plate 202 is always greater than the distance threshold, it means that the amount of snow has not exceeded the bearing range of the wire. Therefore, the analysis and judgment module can judge whether the amount of snow has exceeded the bearing range of the wire by comparing the distance data and the distance threshold. When the judgment result of the accumulation analysis module is that the amount of snow has exceeded the bearing range of the conductor (that is, when the judgment result is yes), the accumulation analysis module will send an instruction to the inspection reminder module, so that the inspection reminder module will emit an alarm sound representing danger. When the judgment result of the accumulation analysis module is that the amount of snow has not exceeded the bearing range of the conductor (that is, when the judgment result is no), the accumulation analysis module will send an instruction to the inspection reminder module, so that the inspection reminder module will emit a prompt sound representing safety, so that the inspection reminder module can feed back the detection and judgment results to relevant technical personnel, thereby providing more real and reliable basis for technical personnel in this field to judge whether it is necessary to inspect the transmission line; Therefore, through the joint establishment of the inspection and control center and the inspection and accumulation auxiliary judgment agency, the inspection and accumulation auxiliary judgment agency can, under the control of the inspection and control center, truly and reliably detect the amount of snow accumulation and judge whether the amount of snow accumulation is within the bearing range of the conductor, thereby providing a more real and reliable basis for judging whether it is necessary to inspect the transmission line, thereby not only avoiding the waste of manpower and resources due to unnecessary inspections to a large extent, but also avoiding the occurrence of missed inspections to a large extent.

[0022] The inspection and control center also includes a visualization display module. The inspection and control terminal 003 is also provided with a patrol assistance positioning module. The accumulation analysis and judgment module and the patrol assistance positioning module are both connected to the visualization module signal. The accumulation analysis and judgment module is connected to the patrol assistance positioning module signal. The visualization display module has a visualization display function. The patrol assistance positioning module is used to obtain location information. When detecting snow accumulation, the accumulation analysis and judgment module will also transmit the distance data detected by the distance sensor 206 to the visualization display module, so that the visualization display module can display the distance data to the relevant technical personnel. The relevant technical personnel can review the distance data, thereby improving the reliability of the system. The patrol assistance positioning module will send the location information to the visualization display module, so that the visualization display module can display the location information to the relevant technical personnel, so that the relevant technical personnel can easily locate the transmission line that needs to be inspected, which can be beneficial to the deployment and planning of the inspection work and improve the practicality of the system.

[0023] See also Figure 5 The snow accumulation detection rod body 205 is composed of a supporting inner rod 2051 and a matching wire jacket 2052 fixedly mounted on the supporting inner rod 2051. The material of the matching wire jacket 2052 is the same as the material of the outermost layer of the conductor, so that the snow accumulation condition on the snow accumulation detection rod body 205 can more truly and accurately reflect the snow accumulation condition on the conductor.

[0024] See also Figure 5 , a fixed plate electric push rod 208 is fixedly installed on the inner wall of the bottom end of the sealing cylinder 201, and the inspection and control module is connected with the fixed plate electric push rod 208 signal. The relevant technical personnel can issue a standby command to the inspection and control module through the inspection control module. After receiving the command, the inspection and control module will control the fixed plate electric push rod 208 to extend, so that the output end of the fixed plate electric push rod 208 is against the bottom end of the piston plate 202 and pushes the piston plate 202 upward for a certain distance, so that the elastic suspension rope 203 can be in a relaxed state at ordinary times, so that the elastic suspension rope 203 can maintain good elasticity, and when the inspection and control module receives the detection command, before starting the distance sensor 206, the inspection and control module will first control the fixed plate electric push rod 208 to retract and reset, so that the piston plate 202 is reset, thereby not affecting the detection. Therefore, through the setting of the fixed plate electric push rod 208, the elastic suspension rope 203 can maintain good elasticity without affecting the detection, thereby ensuring the accuracy of the detection.

[0025] See also Figure 5 A C-shaped air guide tube 207 is provided on the outer wall of the sealing cylinder 201, and the two ends of the air guide tube 207 are respectively located on the upper and lower sides of the piston plate 202, and both ends of the air guide tube 207 are connected with the interior of the sealing cylinder 201 to prevent the air in the sealing cylinder 201 from hindering the upward and downward movement of the piston plate 202, thereby facilitating the detection.

[0026] The second implementation method: Figure 1 , Figure 4-Figure 5 , Figure 7-Figure 8 An intelligent inspection system for power transmission lines is shown. Different from the first embodiment, there are two inspection components 002, one of which is equipped with a snow removal inspection auxiliary component. The snow removal inspection auxiliary component includes a support vertical plate 102 fixedly mounted on a support base 101, and a removal electric push rod 103 is fixedly mounted on the support vertical plate 102. The snow removal inspection auxiliary component also includes a snow removal sleeve 004 matching the inspection rod body 205. A linkage rod 104 is fixedly connected between the output end of the snow removal sleeve 004 and the removal electric push rod 103. The snow removal sleeve 004 is located directly in front of the corresponding inspection rod body 205. The snow removal sleeve 004 consists of an external connecting sleeve 401 and an annular snow removal brush 402 fixedly mounted on the inner wall of the external connecting sleeve 401. The external connecting sleeve 401 and the annular snow removal brush 402 are both arranged in a circular ring shape with a notch at the bottom, and the notch matches the connecting slide rod 204. The inspection and control module is connected to the removal electric push rod 103 by signal.

[0027] Relevant technicians can reasonably set a distance difference threshold through the threshold setting module to further determine whether the amount of snow accumulation has exceeded the tolerance range of the wire. For the sake of description, the inspection component 002 that is not equipped with a snow removal auxiliary inspection component is recorded as A, and the inspection component 002 equipped with a snow removal auxiliary inspection component is recorded as B. After receiving the detection instruction, the inspection and accumulation control module will control A to perform snow accumulation detection alone. After the detection is completed and the detection and judgment results are fed back to the relevant technicians through the inspection reminder module, the relevant technicians can determine whether further detection is needed according to the actual situation (when judging, mainly consider whether environmental factors will affect the detection. For example, wind may affect the detection. If the wind speed is high during the detection, further detection is usually required, such as wind speed. Environmental factor information can be obtained through the meteorological department or other channels), if necessary, the relevant technical personnel can issue an inspection instruction to the inspection and accumulation execution module through the inspection start control module. After receiving the inspection instruction, the inspection and accumulation execution module will control the removal electric push rod 103 to pull the snow removal cover 004 back and forth, so that the snow removal cover 004 clears the snow on the accumulation inspection rod 205 in B, and then start the distance sensor 206 in B (before starting the distance sensor 206 in B, the analysis and judgment module will first control the fixed plate electric push rod 208 in B to retract and reset, so that the piston plate 202 in B is reset), so that the analysis and judgment module further judges whether the amount of snow has exceeded the tolerance range of the wire by analyzing the distance data detected by the two distance sensors 206 according to the distance difference threshold; The distance data detected by the distance sensor 206 in A is recorded as a, and the distance data detected by the distance sensor 206 in B is recorded as b. The analysis and judgment module will first calculate the difference between b and a, and then compare the difference between b and a with the distance difference threshold. Since A and B are in the same environment, environmental factors will have the same impact on A and B, and the snow on the accumulation detection stick 205 in B has been cleared, while the snow on the accumulation detection stick 205 in A remains the same. Therefore, by calculating the difference between b and a, the amount of snow can be detected more accurately without the interference of environmental factors. The more snow is accumulated, the greater the difference between b and a. If the difference between b and a is greater than the distance difference threshold, it means that the amount of snow is too much and has exceeded the tolerance range of the wire. If the difference between b and a is less than the distance difference threshold, it means that the amount of snow has not exceeded the tolerance range of the wire. Therefore, the analysis The accumulation judging module can further judge whether the amount of snow accumulation has exceeded the bearing range of the conductor by analyzing the distance data detected by the two distance sensors 206 according to the distance difference threshold. When the judgment result of the accumulation judging module is that the amount of snow accumulation has exceeded the bearing range of the conductor, the accumulation judging module will send a command to the inspection and reminder module to make the inspection and reminder module emit an alarm sound representing danger. When the judgment result of the accumulation judging module is that the amount of snow accumulation has not exceeded the bearing range of the conductor, the accumulation judging module will send a command to the inspection and reminder module to make the inspection and reminder module emit a prompt sound representing safety. Therefore, through the setting of the two accumulation detection components 002 and the snow removal auxiliary detection component, the amount of snow accumulation can be further detected while effectively eliminating the interference of environmental factors, so that it can more accurately and reliably detect whether the amount of snow accumulation has exceeded the bearing range of the conductor, thereby greatly improving the reliability of the system.

[0028] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
