Description

Technical Field

[0001] This invention relates to the field of power transmission line inspection technology, and more specifically to a high-voltage power transmission line inspection device. Background Technology

[0002] The electricity generated by power plants is not only used by people in the vicinity, but also needs to be transmitted to distant places to meet more needs. This electricity is transmitted using high-voltage transmission lines. Transmission voltage below 220 kV is called high-voltage transmission, transmission voltage between 330 kV and 765 kV is called ultra-high-voltage transmission, and transmission voltage above 1000 kV is called extra-high-voltage transmission. After the electricity is transmitted to the place of consumption, the voltage must be reduced before it can be used. High-voltage transmission lines are divided into cable transmission lines and overhead transmission lines. Cable transmission lines: cables are buried underground, which does not take up space, but construction and maintenance are inconvenient. They are mostly used in urban areas and cross-river lines. Overhead transmission lines: transmission towers are used to suspend conductors and ground wires in the air, maintaining a certain safe distance between conductors, between conductors and ground wires, between conductors and towers, and between conductors and ground obstacles to complete the transmission task. In order to ensure the smooth completion of the transmission task, high-voltage transmission lines need to be inspected.

[0003] When inspecting high-voltage transmission lines, the testing equipment needs to perform simple cleaning on the line surface to ensure accurate test results. However, traditional cleaning equipment needs to wrap around the entire line if it is to clean all four sides. When changing lines, the cleaning equipment cannot be quickly moved away from the perimeter of the line and used to cooperate with the new line. When cleaning high-voltage transmission lines, since there are main lines and various branch lines, the diameters of the lines are different. Traditional cleaning equipment cannot clean different high-voltage transmission lines, which affects the accuracy of subsequent testing.

[0004] Currently, when inspecting high-voltage transmission lines, only the transmission line itself is inspected, but it is impossible to predict the subsequent operation of the transmission line. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide a high-voltage transmission line inspection device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-voltage transmission line inspection device, comprising a control mechanical platform, a movable wheel fixedly connected to the top of the control mechanical platform, a transmission line wire movably connected inside the movable wheel, a connecting platform fixedly connected to the top of each of the two sides of the control mechanical platform, an opening and closing mechanism fixedly connected to the top of each connecting platform, a cleaning mechanism fixedly connected to the top of each opening and closing mechanism, and an intelligent acquisition terminal fixedly connected to the top of the control mechanical platform, the intelligent acquisition terminal being located between the two cleaning mechanisms;

[0007] An adjusting motor is fixedly connected to one side of the top of the connecting platform. A bidirectional threaded rod is fixedly connected to the side of the adjusting motor. The side of the bidirectional threaded rod has two sets of threaded grooves with opposite directions of rotation. The sides of both sets of threaded grooves are threaded with movable plates. The two movable plates move in opposite directions. A support plate is fixedly connected to the side of the movable plate.

[0008] In a preferred embodiment, wind turbines are fixedly connected to the bottom ends of both sides of the control mechanical platform. The wind turbines are located in the direction of movement of the moving wheels, and there are two wind turbines on each side of the control mechanical platform. All the electricity generated by the wind turbines is used by the control mechanical platform, the opening and closing mechanism, and the cleaning mechanism.

[0009] In a preferred embodiment, a limiting plate is fixedly connected to the side of the movable plate away from the support plate, and a limiting groove adapted to the limiting plate is provided at the top of the connecting platform. A connecting plate is fixedly connected to the side of the support plate away from the movable plate, and a limiting rod is movably connected inside the connecting plate. The bottom end of the limiting rod is fixedly connected to the top of the connecting platform.

[0010] In a preferred embodiment, the cleaning mechanism includes two support plates fixedly connected to two movable plates. Each of the two support plates has a fixed block fixedly connected to its side. Each fixed block has a limiting sleeve fixedly connected to its adjacent side. Each limiting sleeve has a rotating connecting cylinder movably connected inside it. Each rotating connecting cylinder has an external gear plate fixedly connected to its side away from the limiting sleeve. The external gear plate is in contact with the support plates and can move relative to them.

[0011] In a preferred embodiment, an output gear is threadedly connected to the side of the external gear plate, a rotating shaft is fixedly connected to the side of the output gear away from the support plate, a servo motor is fixedly connected to the side of the rotating shaft away from the output gear, and the servo motor is fixedly connected to the support plate through a limiting sleeve.

[0012] In a preferred embodiment, the external gear plate has an arc-shaped groove inside, and a sliding column is movably connected in the arc-shaped groove of the external gear plate. A movable limiting strip is fixedly connected to the side of the sliding column away from the external gear plate. The support plate has a limiting groove inside, which allows the movable limiting strip to move. A first cleaning plate and a second cleaning plate are fixedly connected to the side of the movable limiting strip.

[0013] In a preferred embodiment, there are four movable limiting strips, which are distributed at equal angles on the side of the support plate. A first cleaning plate is fixedly connected to the side of two opposite movable limiting strips, and a second cleaning plate is fixedly connected to the side of the other two opposite movable limiting strips. The side of the first cleaning plate is in contact with the side of the second cleaning plate, and the first cleaning plate is close to the support plate, while the second cleaning plate is close to the external gear plate.

[0014] In a preferred embodiment, the control platform includes a data acquisition unit, an analysis unit, a processing unit, and a reporting unit. The data acquisition unit collects temperature data (WD), current data (DL), and grayscale data (HD) from the surface of the power transmission line wires via an intelligent acquisition terminal. The analysis unit receives the data acquired by the acquisition unit and calculates an evaluation value (P). The formula for calculating the evaluation value (P) is as follows: In the formula, η and θ are both weights, and 0≤η≤1, 0≤θ≤1, η+θ=1, C is the correlation coefficient of the power transmission line wire under temperature data and current data, and the analysis unit sends the calculated evaluation value P to the control unit.

[0015] In a preferred embodiment, the processing unit receives the evaluation value P calculated by the analysis unit and compares it with its internal threshold Y. When the evaluation value P ≥ the threshold Y, the processing unit sends a danger command to the reporting unit. When the evaluation value P < the threshold Y, the processing unit does not send a command to the reporting unit. The reporting unit receives the danger command and reports the location information of the danger command and the data information collected by the acquisition unit to the management personnel.

[0016] In a preferred embodiment, when the intelligent acquisition terminal acquires grayscale data information HD from the surface of the power transmission line wire, the calculation formula for the grayscale data information HD is HD=0.3R+0.58G+0.12B, where R is the red image, G is the green image, and B is the blue image, and R, G, and B are all within the grayscale value range of 0-255.

[0017] The technical effects and advantages of this invention are as follows:

[0018] 1. When the adjusting motor of the present invention starts, it drives the moving plate to rotate. When the moving plate rotates, the moving plates on its two threaded grooves move towards each other or in opposite directions. When the moving plates move towards each other, the support plate inside the cleaning mechanism separates. At this time, the cleaning mechanism can be removed from the side of the power transmission line. When it is used with a new power transmission line, the two moving plates move towards each other, thereby quickly fixing it. This invention can be quickly replaced on different power transmission lines.

[0019] 2. During cleaning, the servo motor starts and drives the output gear to rotate through the rotating shaft. When the output gear rotates, it drives the external gear plate to rotate. When the external gear plate rotates, it causes the sliding column to drive the moving limit bar to move. When the moving limit bar moves, it drives the first cleaning plate and the second cleaning plate to move inward or outward, so as to cooperate with the power transmission line wires of different diameters. The two sets of first cleaning plates and second cleaning plates can ensure that power transmission line wires of different diameters are cleaned.

[0020] 3. This invention collects temperature data (WD), current data (DL), and grayscale data (HD) from the surface of power transmission line wires. The evaluation value P calculated using these three types of data can accurately reflect the condition of the power transmission line wires themselves. When the calculated evaluation value P ≥ the threshold Y, there is a risk of damage to the power transmission line wires. Therefore, this application can make predictions and report them in a timely manner to avoid sudden damage. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The high-voltage transmission line inspection device involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figure 1 and Figure 8 This invention provides a high-voltage transmission line inspection device, including a control mechanical platform 1. A movable wheel 6 is fixedly connected to the top of the control mechanical platform 1, and a transmission line wire 8 is movably connected inside the movable wheel 6. Connecting platforms 2 are fixedly connected to the tops of both sides of the control mechanical platform 1. Opening and closing mechanisms 4 are fixedly connected to the tops of both connecting platforms 2, and cleaning mechanisms 5 are fixedly connected to the tops of both opening and closing mechanisms 4. An intelligent data acquisition terminal 7 is fixedly connected to the top of the control mechanical platform 1, located between the two cleaning mechanisms 5. Wind turbine generators 3 are fixedly connected to the bottoms of both sides of the control mechanical platform 1, located in the direction of movement of the movable wheel 6. There are two wind turbine generators 3 on each side of the control mechanical platform 1. All the electricity generated by the wind turbine generators 3 is used by the control mechanical platform 1, the opening and closing mechanisms 4, and the cleaning mechanisms 5.

[0032] In this embodiment, when the control mechanical platform 1 controls the moving wheel 6 to rotate, the entire device can move above the power transmission line 8. Since the power transmission line 8 is generally located at a high position, where the wind force is stronger, the use of the wind turbine 3 can generate more electricity, which can be used by the control mechanical platform 1, the opening and closing mechanism 4, and the cleaning mechanism 5, thus achieving energy saving and increasing the distance that this application can move and the number of lines that can be inspected.

[0033] Reference Figure 2 , Figure 3as well as Figure 4 An adjusting motor 401 is fixedly connected to one side of the top of the connecting platform 2. A bidirectional threaded rod 402 is fixedly connected to the side of the adjusting motor 401. The side of the bidirectional threaded rod 402 has two sets of threaded grooves with opposite directions of rotation. The sides of the two sets of threaded grooves are threadedly connected to a moving plate 403. The two moving plates 403 move in opposite directions. A support plate 501 is fixedly connected to the side of the moving plate 403. A limit plate 404 is fixedly connected to the side of the moving plate 403 away from the support plate 501. A limit groove adapted to the limit plate 404 is opened at the top of the connecting platform 2. A connecting plate 405 is fixedly connected to the side of the support plate 501 away from the moving plate 403. A limit rod 406 is movably connected inside the connecting plate 405. The bottom end of the limit rod 406 is fixedly connected to the top of the connecting platform 2.

[0034] In this embodiment, when the adjusting motor 401 drives the bidirectional threaded rod 402 to rotate, the side of the bidirectional threaded rod 402 has two sets of threaded grooves with opposite directions of rotation. Therefore, when the bidirectional threaded rod 402 rotates, the moving plates 403 move towards or away from each other. When the moving plates 403 move towards each other, the support plate 501 inside the cleaning mechanism 5 separates. At this time, the cleaning mechanism 5 can be removed from the side of the power transmission line 8. When it is used with a new power transmission line 8, the two moving plates 403 move towards each other, thereby quickly fixing it. This allows the invention to be quickly replaced on different power transmission lines 8. The limiting plate 404 can move in the limiting groove at the top of the connecting platform 2, thereby ensuring the stability of the limiting plate 404 when it moves. The connecting plate 405 also supports the cleaning mechanism 5, thereby ensuring the stability of the entire cleaning mechanism 5 when it is working.

[0035] Reference Figure 5 , Figure 6 , Figure 7 as well as Figure 8The cleaning mechanism 5 includes two support plates 501 fixedly connected to two movable plates 403. Each support plate 501 has a fixed block 502 fixedly connected to its side. Limiting sleeves 503 are fixedly connected to the sides of the fixed blocks 502 that are close to each other. Rotating connecting cylinders 504 are movably connected inside each limiting sleeve 503. An external gear plate 505 is fixedly connected to the side of the rotating connecting cylinder 504 away from the limiting sleeve 503. The external gear plate 505 is in contact with the support plates 501 and can move relative to them. An output gear 508 is threadedly connected to the side of the external gear plate 505. A rotating shaft 507 is fixedly connected to the side of the output gear 508 away from the support plate 501. A servo motor 506 is fixedly connected to the side of the rotating shaft 507 away from the output gear 508. The servo motor 506 is fixedly connected to the support plate 501 through the limiting sleeves 503. The internal... The support plate 501 has an arc-shaped groove, and a sliding column 509 is movably connected in the arc-shaped groove of the external gear plate 505. A movable limiting strip 510 is fixedly connected to the side of the sliding column 509 away from the external gear plate 505. A limiting groove is provided inside the support plate 501 to allow the movable limiting strip 510 to move. A first cleaning plate 511 and a second cleaning plate 512 are fixedly connected to the side of the movable limiting strip 510. There are four movable limiting strips 510, which are distributed at equal angles on the side of the support plate 501. The first cleaning plate 511 is fixedly connected to the side of two opposite movable limiting strips 510, and the second cleaning plate 512 is fixedly connected to the side of the other two opposite movable limiting strips 510. The sides of the first cleaning plate 511 and the second cleaning plate 512 are in contact, with the first cleaning plate 511 closer to the support plate 501 and the second cleaning plate 512 closer to the external gear plate 505.

[0036] In this embodiment, when the output gear 508 rotates, it drives the external gear plate 505 to rotate. When the external gear plate 505 rotates, it drives the sliding column 509 to move. When the sliding column 509 moves, it drives the first cleaning plate 511 and the second cleaning plate 512 to move. At this time, it cooperates with the power transmission line wires 8 of different diameters. The two first cleaning plates 511 are located in front of the cleaning, that is, on the side close to the support plate 501. The part not covered by the junction of the two first cleaning plates 511 can be cleaned by the two second cleaning plates 512, thereby cleaning the entire second cleaning plate 512 thoroughly and completely. The support plate 501 is connected to the limiting sleeve 503 through the fixing block 502, and also connects to the servo motor 50. The 6 provides support, and the interior of the limiting sleeve 503 is a rotatable rotating connecting cylinder 504. The external gear plate 505 can also rotate, allowing the external gear plate 505 of this application to rotate. When the support plate 501 separates, the limiting sleeve 503 is driven to separate through the fixing block 502. The moving wheel 6 can be divided into two parts. The two limiting sleeves 503 are in contact with each other, and the rotating connecting cylinders 504 are also in contact with each other simultaneously. At this time, the external gear plate 505 and the support plate 501 will also be in contact. The cleaning mechanism 5 is in contact as a whole, allowing the external gear plate 505 to rotate normally. The side of the rotating connecting cylinder 504 can enter the limiting groove of the limiting sleeve 503, ensuring the accuracy of the cleaning mechanism 5 after contact.

[0037] Furthermore, the control platform 1 includes a data acquisition unit, an analysis unit, a processing unit, and a reporting unit. The data acquisition unit collects temperature data (WD), current data (DL), and grayscale data (HD) from the surface of the power transmission line wire 8 via the intelligent acquisition terminal 7. The analysis unit receives the data acquired by the acquisition unit and calculates the evaluation value P. The formula for calculating the evaluation value P is as follows: In the formula, η and θ are both weights, and 0≤η≤1, 0≤θ≤1, η+θ=1. C is the correlation coefficient of the power transmission line wire 8 under temperature data and current data. The analysis unit sends the calculated evaluation value P to the control unit. The processing unit receives the evaluation value P calculated by the analysis unit and compares it with its internal threshold Y. When the evaluation value P≥threshold Y, the processing unit sends a danger command to the reporting unit. When the evaluation value P<threshold Y, the processing unit does not send a command to the reporting unit. The reporting unit receives the danger command and reports the location information of the danger command and the data information collected by the acquisition unit to the management personnel. When the intelligent acquisition terminal 7 collects the gray value data information HD of the surface of the power transmission line wire 8, the calculation formula of the gray value data information HD is HD=0.3R+0.58G+0.12B, where R is the red image, G is the green image, and B is the blue image, and R, G, and B are all within the gray value range of 0-255.

[0038] In this embodiment, the application collects temperature data (WD), current data (DL), and grayscale data (HD) from the surface of the power transmission line wire 8. The evaluation value P calculated using these three types of data can accurately reflect the condition of the power transmission line wire 8. For example, when the temperature is high or the current is high, the power transmission line wire 8 is prone to damage. When the current is low, the cable is damaged, and its grayscale value increases. Therefore, when the evaluation value P calculated by this application is greater than or equal to the threshold Y, the power transmission line wire 8 is at risk of damage. Timely reporting is necessary to prevent sudden damage. Thus, this application can make predictions and remind staff to perform maintenance. In addition, it should be noted that collecting temperature data, current data, and grayscale data from the surface of the power transmission line wire 8 through the intelligent acquisition terminal 7 is a conventional technical means in this field, and this application does not limit it in detail.

[0039] The working principle of this invention is as follows: During inspection, the servo motor 506 is started. When the servo motor 506 starts, it drives the output gear 508 to rotate through the rotating shaft 507. When the output gear 508 rotates, it drives the external gear plate 505 to rotate. When the external gear plate 505 rotates, it drives the sliding column 509 to move. When the sliding column 509 moves, it drives the first cleaning plate 511 and the second cleaning plate 512 to move. At this time, it cooperates with the power transmission line wires 8 of different diameters. The two first cleaning plates 511 are located in front of the cleaning. The part that is not covered at the junction of the two first cleaning plates 511 can be cleaned by the two second cleaning plates 512, thereby cleaning the entire second cleaning plate 512 thoroughly and completely.

[0040] When the control platform 1 starts the moving wheel 6, the first cleaning plate 511 and the second cleaning plate 512 clean the power transmission line wire 8. The cleaned power transmission line wire 8 is then inspected to ensure accuracy. When replacing the line, the adjusting motor 401 controls the bidirectional threaded rod 402 to rotate. The rotation of the bidirectional threaded rod 402 causes the two moving plates 403 to move in opposite directions. As the moving plates 403 move, they drive the support plates 501 to move in opposite directions, causing the two support plates 501 to separate. When the support plates 501 separate, they drive the limiting sleeve 503 to separate via the fixing block 502. The limiting sleeve 503, moving back and forth, drives the external gear plate 505 to separate via the rotating connecting cylinder 504. Therefore, the moving... The moving wheel 6 can be divided into two parts. After being separated from the original power transmission line 8, when it is used with the new power transmission line 8, the adjusting motor 401 controls the bidirectional threaded rod 402 to reverse. When the bidirectional threaded rod 402 reverses, the moving plate 403 moves inward synchronously, i.e., moves towards each other. At this time, the two limiting sleeves 503 are in contact with each other, and the rotating connecting cylinders 504 are also in contact synchronously. At this time, the external gear plate 505 and the support plate 501 are also in contact. The entire cleaning mechanism 5 is in contact, so that the external gear plate 505 can rotate normally, and the side of the rotating connecting cylinder 504 can enter the limiting groove of the limiting sleeve 503 to ensure the accuracy of the cleaning mechanism 5 after contact.
