Description

Technical Field

[0001] This invention belongs to the field of power transmission line maintenance technology, specifically an intelligent power transmission line maintenance device. Background Technology

[0002] Currently, my country's overhead power transmission lines are erected at high outdoor locations. Coupled with the exposure to wind and rain, these lines are prone to problems and require maintenance workers to carry out repairs. However, the existing method involves workers manually crawling to the repair location to perform the repairs. This method is extremely physically demanding for the workers, and the prone posture makes their movements inflexible, resulting in low efficiency and safety risks.

[0003] Patent CN116722480B discloses an intelligent maintenance device for power transmission lines, relating to the field of power transmission line maintenance technology. It includes a base with support rods fixedly connected to both sides. A conversion element is slidably mounted on the support rods for crossing different power transmission lines. A traveling element is mounted on the conversion element for movement on the power transmission line. A driving element is mounted on the base as a driving source for crossing movement. An inspection and repair element is mounted on the top of the base for detecting and repairing surface defects on the power transmission line. The inspection and repair element includes two mating rings, with toothed rings rotatably mounted on each ring. One toothed ring has a camera detection device mounted on it, and the other toothed ring has a repair element mounted on it. This invention can cross different cables, travel on different cables, and perform inspection and repair operations, reducing the number of manual installations and effectively improving inspection and repair efficiency. However, during cleaning, it can only inspect and repair one cable at a time, resulting in slow repair efficiency. Furthermore, when cleaning impurities on the cable using only a scraper ring, the strong auxiliary force of the impurities can easily damage the cable's surface insulation during the scraping process.

[0004] Meanwhile, during the maintenance process, in addition to the fixed debris attached to the cable surface, there may also be bird droppings and other corrosive substances attached, which may affect the safety of the cable. Furthermore, the maintenance process also requires repairing the damaged parts of the cable, which makes the maintenance process time-consuming and affects the overall maintenance efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems. This invention provides an intelligent maintenance device for power transmission lines, which has the advantage of quickly determining the working status of power transmission cables.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent maintenance device for transmission lines, comprising a bearing assembly, four adjusting rods respectively connected to the outer periphery of the bearing assembly, a maintenance assembly connected to the end of the adjusting rod away from the bearing assembly, and an elastic rod connected to one end face of the bearing assembly, a driving assembly connected to the end of the elastic rod away from the bearing assembly, the driving assembly being at the same horizontal position as the bearing assembly; The bearing assembly includes a placement block, a sliding cavity is formed through the placement block, a rotating ring is connected inside the sliding cavity, a plurality of abutment blocks are connected inside the rotating ring, and the side of the placement block away from the abutment blocks is connected to four elastic rods respectively. The maintenance assembly includes a connecting ring, on which a plurality of telescopic rods are connected. An identification part is connected to one end of each telescopic rod away from the connecting ring. The identification part includes an arc-shaped plate. An electromagnetic cavity is formed on the side of the arc-shaped plate away from the telescopic rods. A detection spring is connected inside the electromagnetic cavity. A moving block is connected to one end of the detection spring away from the arc-shaped plate, and the moving block is slidably connected to the arc-shaped plate.

[0007] Preferably, the bearing component further includes a telescopic block, one end of which is connected to the abutment block, a return spring is connected to the end of the telescopic block away from the abutment block, the end of the return spring away from the telescopic block is connected to the rotating ring, and the telescopic block is slidably connected to the rotating ring.

[0008] Preferably, the maintenance component further includes a through hole, and the identification parts are all located inside the through hole, and the diameter of the through hole is larger than the diameter of the power transmission cable.

[0009] Preferably, the drive assembly includes two protective plates, with a working cavity formed at one end of the two protective plates that are close to each other. A drive wheel is rotatably disposed in the working cavity, and the drive wheel and the sliding cavity are connected to the same cable.

[0010] Preferably, the elastic rod vibrates elastically according to the working state of the drive wheel on the cable.

[0011] Preferably, the placement block consists of two assembly blocks, and each assembly block is connected to two maintenance components.

[0012] Preferably, a rotating shaft is connected to the connecting ring, allowing a portion of the connecting ring to rotate around the rotating shaft and open the through hole.

[0013] Preferably, a thermal sensor is connected inside the moving block.

[0014] Preferably, a control center is connected within the bearing component.

[0015] Preferably, the movable block is made of a rubbery material, and the end of the arc-shaped plate away from the connecting ring is provided with a cleaning layer.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the cooperation of the set drive component, load-bearing component and maintenance component, the maintenance of power transmission cables can be realized. At the same time, during the driving process, the drive component can cooperate with the elastic rod and load-bearing component to clean impurities from the target cable. When the maintenance component is used to maintain the cable, it can identify the cable that needs to be treated according to the change of the detection spring. When the detection spring extends and the temperature detected by the thermal sensor rises, the moving block can be used to repair the damaged position to ensure the safety of the cable during use.

[0017] 2. The position of the contact block can be effectively adjusted by the reset spring and telescopic block. The telescopic block actively adjusts the position of the contact block, making the inspection device suitable for the inspection of power transmission cables of different specifications. When the contact block detects an abnormal protrusion, the position of the contact block can be adjusted by the reset spring. The size of the foreign object can be judged by the height of the reset spring. At the same time, the elastic force of the reset spring can be used to increase the pressure between the contact block and the abnormal protrusion, which facilitates the cleaning of the contact block.

[0018] 3. By using the arc-shaped plate and electromagnetic cavity, it is possible to ensure that when the moving block detects an abnormal object, the electromagnetic cavity can store and hide the moving block, allowing the arc-shaped plate to come into contact with the target impurity. On the one hand, this avoids excessive wear of the moving block's adhesive material, and on the other hand, it ensures efficient cleaning of impurities by allowing the arc-shaped plate to fully contact the impurity.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1-7 As shown, an intelligent maintenance device for power transmission lines includes a carrier component 1 for moving and mounting the entire device. Since a high-voltage transmission cable consists of five cables, three of which transmit electrical energy and the remaining two are auxiliary cables, four adjusting rods 2 are connected to the outer periphery of the carrier component 1. The length of each adjusting rod 2 is adjustable to adjust the position of a maintenance component 3. The end of each adjusting rod 2 away from the carrier component 1 is connected to the maintenance component 3. Because the number of maintenance components 3 is the same as the number of adjusting rods 2, the maintenance of the high-voltage transmission cable is achieved through the cooperation between the carrier component 1 and the four maintenance components 3. Two elastic rods 4 are connected to one end face of the carrier component 1. Utilizing the elasticity of the elastic rods 4, when the drive component 5 moves onto the cable, it can... The spacing between the drive components 5 can be actively adjusted to ensure that the drive components 5 can move on the cable. The end of the elastic rod 4 away from the bearing component 1 is connected to the drive component 5. Under the driving action of the drive component 5, the maintenance device can be moved. At the same time, during the movement of the drive component 5, the surface condition of the cable where the drive component 5 is located can be judged according to the movement of the drive component 5 on the cable. That is, when there is a protrusion on the cable, the drive component 5 can drive the elastic rod 4 to bend. At the same time, the elastic rod 4 can transmit the bending status to the control center, thereby cleaning the abnormal area. The drive component 5 and the bearing component 1 are at the same horizontal position, and thus the drive component 5 and the bearing component 1 are both on the same cable, ensuring that the cable can be maintained while the maintenance device is moving.

[0022] The supporting component 1 includes a placement block 101, which is also made of insulating material. A sliding cavity 103 is formed through the placement block 101, through which the cable can pass. The cable can pass through the driving component 5 and the sliding cavity 103 respectively. A rotating ring 102 is connected in the sliding cavity 103. The rotating ring 102 can rotate relative to the placement block 101, thereby driving the abutment block 104 to rotate. Several abutment blocks 104 are connected to the inner side of the rotating ring 102. The outer end of the cable in the target area is inspected and cleaned by the abutment blocks 104. The side of the placement block 101 away from the abutment blocks 104 is connected to four elastic rods 4 respectively. That is, during the driving process of the driving component 5 or during the movement of the abutment blocks 104 on the cable, the outer end of the cable is judged according to the working process of the driving component 5 and the working state of the abutment blocks 104, so as to clean the abnormal position of the cable.

[0023] To facilitate the identification and inspection of transmission lines, the maintenance component 3 includes a connecting ring 301. The connecting ring 301 can wrap around the cable, ensuring accurate cable detection. For safety during use, the connecting ring 301 is made of insulating material. Several telescopic rods 304 are connected to the inner ring of the connecting ring 301. These telescopic rods 304 can adjust the position of the identification unit 303, thereby adjusting the pressure between the identification unit 303 and the cable body, ensuring the accuracy of the identification unit 303's detection. The end of the telescopic rod 304 furthest from the connecting ring 301 is connected to the identification unit 303. The movement of the identification unit 303 on the cable is used to determine the condition of the transmission line surface, and the determined data can be uploaded to the control center. The identification unit 303 includes an arc-shaped plate 3031, which ensures that the identification unit 303 makes complete and uniform contact with the cable, preventing abnormal stress. An electromagnetic cavity is provided on the side of the arc-shaped plate 3031 away from the telescopic rod 304. A detection spring 3032 is connected inside the electromagnetic cavity, and the magnetic changes of the electromagnetic cavity can actively adjust the extension and contraction of the detection spring 3032. A moving block 3033 is connected to the end of the detection spring 3032 away from the arc-shaped plate 3031, and the moving block 3033 is slidably connected to the arc-shaped plate 3031. During normal use, the electromagnetic cavity is in an unenergized state, thereby ensuring that the detection spring 3032 is in a normal working state. When the moving block 3033 comes into contact with the cable, it can compress the detection spring 3032. During the detection of the cable by the moving block 3033, if there are abnormal protrusions on the cable, it will also cause the pressure value between the moving block 3033 and the cable to change, thereby changing the compression degree of the detection spring 3032, thus completing the identification and detection of the cable status.

[0024] Furthermore, in the event of cable identification anomalies, the electromagnetic changes in the electromagnetic cavity can control the elastic changes of the detection spring 3032, thereby causing the moving block 3033 to hide inside the arc plate 3031, ensuring that the arc plate 3031 will not cause wear to the surface of the moving block 3033 when cleaning the cable surface.

[0025] To facilitate adjustment of the pressure between the contact block 104 and the cable, and to facilitate cleaning of the cable surface by the contact block 104, the bearing assembly 1 further includes a telescopic block 105. One end of the telescopic block 105 is connected to the contact block 104. The distance between the contact block 104 and the rotating ring 102 is adjusted by the telescopic block 105, thereby ensuring stable working efficiency of the contact block 104. A return spring 106 is connected to the end of the telescopic block 105 away from the contact block 104. The return spring 106 can control the contact depth between the contact block 104 and the cable, so that when there are objects that are difficult to clean on the cable, it can... The movement depth of the contact block 104 is controlled by the extension and retraction of the return spring 106 to complete the cleaning of foreign objects on the cable. The end of the return spring 106 away from the telescopic block 105 is connected to the rotating ring 102, and the telescopic block 105 is slidably connected to the rotating ring 102. When the telescopic block 105 adjusts the position of the contact block 104, the return spring 106 will not be compressed. When the telescopic block 105 maintains its length, after the contact block 104 comes into contact with the cable, the contact block 104 and the telescopic block 105 can slide relative to the rotating ring 102 when the return spring 106 undergoes an elastic change.

[0026] To facilitate the effective detection of cable status by the maintenance component 3, the maintenance component 3 specifically includes a through hole 302, and the identification parts 303 are all located inside the through hole 302. The diameter of the through hole 302 is larger than the diameter of the power transmission cable, so that the cable can pass through the through hole 302 without affecting the use of the cable itself. The cable is wrapped by the connecting ring 301 to avoid damage to the maintenance device during the maintenance process.

[0027] To ensure that the maintenance device can move on the power transmission cable, the drive assembly 5 specifically includes two protective plates 501, which support the power source and working components. The two protective plates 501 have a working cavity 502 at their close ends, which constrains the cable. A drive wheel 503 is rotatably installed inside the working cavity 502. The drive wheel 503 contacts the cable surface. The drive wheel 503 and the sliding cavity 103 are connected to the same cable. The rotation of the drive wheel 503 drives the device to move. It should be noted that the drive wheel 503 can fully contact the cable surface, and the drive wheel 503 will not damage the cable sheath when it rotates on the cable surface.

[0028] Specifically, to ensure that the bearing assembly 1 is not interfered with by impurities on the cable during movement, the elastic rod 4 will elastically fluctuate according to the working state of the drive wheel 503 on the cable. When the drive wheel 503 rolls over the impurities, the impurities will cause the drive wheel 503 to fluctuate, thereby causing the elastic rod 4 to elastically deform. At the same time, the elastic rod 4 will upload its own deformation to the control center to identify the size of the impurities on the cable, so as to facilitate the adjustment of the bearing assembly 1 to clean the target area.

[0029] Specifically, to facilitate a quick connection between the carrier component 1 and the cable, the placement block 101 is composed of two assembly blocks, which are detachably connected. This allows the placement block 101 to be divided into two assembly blocks when needed, and then the two assembly blocks can be moved to the target area and reassembled. It should be noted that, to facilitate the connection of the two assembly blocks, each of the two assembly blocks has a snap-fit ​​buckle at one end opposite to the other, and each assembly block is connected to two maintenance components 3. In this solution, the two assembly blocks are composed of two identical components, which ensures the stability of the carrier component 1 during use and facilitates a quick connection between the carrier component 1 and the cable.

[0030] Specifically, in order to facilitate the connection between the maintenance component 3 and the cable, the connecting ring 301 is configured as a two-part structure. The connecting ring 301 is connected to a rotating shaft, so that a part of the connecting ring 301 can rotate around the rotating shaft to open the through hole 302. The part connected to the adjusting rod 2 is in a stationary state, while the side opposite to the adjusting rod 2 can rotate around the rotating shaft, thereby controlling the opening and closing of the through hole 302. This facilitates the quick constraint of the target cable and improves the ease of use of the device.

[0031] Specifically, during prolonged use, the outer rubber of cables can easily become damaged due to weathering or external factors. This can cause changes in the cable's resistance during power transmission, leading to abnormal temperature increases in certain areas of the transmission cable. A thermistor is installed within the moving block 3033. During device movement, the sliding contact between the moving block 3033 and the cable allows the thermistor to detect the cable's temperature and promptly upload data on any abnormal temperatures, enabling the maintenance device to repair the target area.

[0032] Specifically, a control center is connected inside the bearing component 1. The control center can receive the usage data of the electronic components in the maintenance device and control the electronic components of the device according to the usage data.

[0033] Specifically, to ensure that the identification unit 303 can move on the cable during the cable inspection process and can clean impurities when the identification unit 303 detects them, the moving block 3033 is made of a rubber material. When the rubber material comes into contact with the cable surface, it can allow the moving block 3033 to slide on the cable surface when driven by the drive component 5. The end of the arc plate 3031 away from the connecting ring 301 is provided with a cleaning layer, which is made of abrasive material. After the moving block 3033 detects impurities, the detection spring 3032 is contracted by the electromagnetic cavity, which drives the moving block 3033 to move closer to the arc plate 3031, so that the cleaning layer on the arc plate 3031 can contact the cable. The movement of the device realizes the cleaning of impurities on the cable.

[0034] Meanwhile, when the thermal sensor detects an abnormal cable temperature, it means that the rubber on the cable is damaged. At this time, the moving block 3033 can be used to contact the gap, and the abnormal temperature and the movement of the moving block 3033 can melt the rubber material, so that the rubber material can perform preliminary repair on the damaged area and reduce the risk caused by exposure.

[0035] When the cable is not being inspected, the through hole 302 is closed, the placement block 101 is spliced, the adjusting rod 2 is shortened, and the inspection device is not moved onto the power transmission line.

[0036] When the power transmission cable needs to be inspected, the connecting ring 301 is rotated to open the through hole 302, and the two assembly blocks are separated from each other. At the same time, the rotating ring 102 is also separated from the placement block 101, and then the two assembly blocks are moved to the cable that needs to be inspected, so that the cable is opposite to the sliding cavity 103. At the same time, the two assembly blocks are moved to the side closer to each other and spliced ​​to form the placement block 101, with the cable located inside the sliding cavity 103. During this process, the drive wheel 503 and the sliding cavity 103 synchronously restrict the target cable. At the same time, the position of the inspection component 3 is adjusted according to the position of other cables. That is, the length of the adjusting rod 2 is adjusted according to the position of the cable so that the cable can be moved into the through hole 302, thereby realizing the rapid installation of the inspection device on the cable.

[0037] For ease of description, only one of the maintenance components 3 and the supporting component 1 will be described here. After the maintenance device has completed the constraint of the cable, the device is adjusted according to the distance between the different cables and the moving block 3033 and the contact block 104. That is, the length of the telescopic rod 304 is adjusted by the control center to move the position of the identification part 303 so that the identification part 303 can be close to the cable, ensuring that the identification part 303 can effectively identify the working condition of the cable surface. It should be noted that when the identification part 303 is close to the cable, it only means that the moving block 3033 and the cable have a relative force. The return spring 106 is in a semi-compressed state, and the cleaning layer is not in contact with the cable. Then, the position of the contact block 104 is adjusted by the telescopic block 105, so that the contact block 104 is in contact with the cable surface, but there is no interaction force between them. This ensures that the contact block 104 can move on the cable surface without damaging the rubber on the cable surface. It also facilitates the detection accuracy of the device when abnormal conditions occur on the cable surface, and ensures that the control center can send maintenance instructions in a timely manner according to the detection situation. After the adjustment of the contact block 104 and the identification unit 303 is completed, wait for the drive component 5 to drive the maintenance device to carry out the maintenance of the cable.

[0038] Furthermore, during the adjustment process, the distance between the cable and each contact block 104 is the same, the deformation of the return spring 106 is the same, and the pressure of the identification part 303 on the cable is the same, which facilitates the control center to identify and detect the data.

[0039] After the support assembly 1 and the inspection assembly 3 have completed the spacing adjustment with the cable, the control center controls the drive assembly 5 to start working, that is, controls the drive wheel 503 to start rotating, causing relative movement between the drive wheel 503 and the cable, thereby driving the support assembly 1 and the inspection assembly 3 to move along the cable, thus beginning the identification of the cable surface condition. At the same time, when the drive wheel 503 moves relative to the cable, abnormal depressions or protrusions on the cable surface may affect the movement path of the drive wheel 503. Furthermore, due to the elastic rod 4, during the movement of the drive wheel 503, any abnormal depressions or protrusions may occur. When the cable undulates, the drive wheel 503 can move the protective plate 501, which in turn causes the elastic rod 4 to undergo elastic deformation. At the same time, the elastic deformation of the elastic rod 4 is transmitted to the control center. The control center analyzes the deformation direction and magnitude of the elastic rod 4 to determine the abnormality of the cable. That is, when one elastic rod 4 moves away from the other elastic rod 4, it means that there is an abnormal protrusion at the point where the drive wheel 503 moves. When both elastic rods 4 move away from each other at the same time, and no other components used by the connecting cable appear on the movement path, it means that there is an abnormal protrusion at the location.

[0040] When the elastic rod 4 transmits the abnormal status to the control center, the control center adjusts the drive wheel 503 to continue driving, causing the placement block 101 to be in the abnormal position. As the placement block 101 moves to the abnormal protrusion position, the protrusion drives the contact block 104 to move closer to the placement block 101. Simultaneously, this compresses the return spring 106. The position and height of the protrusion can be re-identified based on the compression of the return spring 106, and the pressure between the contact block 104 and the cable is adjusted by the degree of compression of the return spring 106, thereby increasing the speed at which the contact block 104 removes foreign objects. Finally, the control center controls the rotation of the rotating ring 102, causing the contact block 104 to rotate, thus achieving the desired effect on the cable. The abnormal protrusions on the cable are cleaned. During the cleaning process, different rotation modes are selected according to the changes in the elastic rods 4. When only one side of the elastic rods 4 deforms, and after confirmation by the return spring 106, the control center controls the rotating ring 102 to reciprocate only at the protrusion position. This avoids the contact block 104 from contacting the cable and rotating under the action of the return spring 106, which could damage the rubber on the surface of the cable. Thus, by utilizing the cooperation between the rotating ring 102 and the contact block 104, foreign objects are cleaned only in the target area. When both elastic rods 4 deform, and the return spring 106 deforms, the rotating ring 102 is controlled to rotate, thereby improving the cleaning efficiency of foreign objects.

[0041] When the drive component 5 encounters foreign objects during the drive process, and the carrier component 1 does not detect any foreign objects on other parts of the cable during the movement, the carrier component 1 only ensures the stability of the maintenance component 3 during the movement.

[0042] As the inspection component 3 moves along with the carrier component 1, it identifies and detects the cable status within the through hole 302. When the inspection component 3 moves along the cable, if the cable is in a normal state, the moving block 3033 and the detection spring 3032 remain unchanged. However, if the detection spring 3032 experiences abnormal compression during the movement of the moving block 3033, it indicates that there is a protrusion in the area traversed by the inspection component 3. The detection spring 3032 then transmits the compression data to the control center. The control center then energizes the electromagnetic cavity, causing the detection spring 3032 to actively compress, positioning the moving block 3033 within the electromagnetic cavity to prevent contact with impurities on the cable. Simultaneously, the length of the telescopic rod 304 is adjusted according to the compression of the detection spring 3032, bringing the arc plate 3031 closer to the cable. The cleaning layer removes impurities from the cable and makes contact with them. Then, the control center regulates the drive component 5 to drive the arc plate 3031 to move back and forth, thereby removing impurities from the cable. When the moving block 3033 moves, the detection spring 3032 extends, and the thermal sensor detects a high-temperature area during the movement, indicating that the cable is damaged. At this time, the drive component 5 is not driven, so that the moving block 3033 is heated in the abnormal temperature area, causing the surface of the moving block 3033 to soften. Then, the drive component 5 moves back and forth, driving the moving block 3033 to move back and forth. The adhesive material of the moving block 3033 is used to repair the damaged area, ensuring the safety of the cable during power transmission and reducing power loss during power transmission.

[0043] To ensure that the surface of the moving block 3033 melts to effectively repair the damaged area, if necessary, a metal strip that can be electromagnetically heated can be provided on the side of the moving block 3033 away from the connecting ring 301. Then, the electromagnetic cavity can heat the metal strip without controlling the detection spring 3032, thereby cooperating with the area with abnormal temperature to soften the surface of the moving block 3033 and improve the repair efficiency of the cable.

[0044] By cooperating with the drive component 5, the bearing component 1, and the maintenance component 3, the power transmission cable can be maintained. During the operation of the drive component 5, the drive component 5 can work with the elastic rod 4 and the bearing component 1 to clean impurities from the target cable. When the maintenance component 3 is used to maintain the cable, it can identify the cable that needs to be treated based on the changes in the detection spring 3032. When the detection spring 3032 extends and the temperature detected by the thermal sensor rises, the moving block 3033 can be used to repair the damaged area to ensure the safety of the cable during use.
