Description

Technical Field

[0001] This invention relates to the field of diagnostic device technology, and in particular to a fault diagnosis device and method for multi-branch new energy grid-connected lines. Background Technology

[0002] When multi-branch new energy grid-connected lines are put into use, in order to ensure the safe and stable transmission of the medium, it is necessary to regularly inspect and diagnose the lines to facilitate the timely elimination of faults. Fault diagnosis devices are required for fault diagnosis and detection of the lines.

[0003] For example, patent application number CN202011048534.3 discloses a fault diagnosis device for power transmission lines between professional poles and towers, including a protective box, a first support rod, an ammeter body, a handle, a clamping device, a slot, a connecting line, a grip, and a telescopic rod. This fault diagnosis device, through the arrangement of the first support rod, ammeter body, clamping device, telescopic rod, clamping block, arc plate, concave wheel, and second support rod, allows power maintenance personnel to adjust the height of the clamping block using the telescopic rod. Then, the concave wheel is engaged above the power transmission line, and the first and second support rods are pulled downwards, causing the arc plate to contact the line. Current can then flow through the connecting line to the ammeter body, thereby diagnosing whether there is a fault in the line between the first and second support rods. This facilitates quick and convenient troubleshooting and diagnosis of various parts of the line by power maintenance personnel.

[0004] Existing line fault diagnosis devices, such as those mentioned above, are typically used by hand, moving the detection structure along the line to perform the detection and diagnosis. However, due to the numerous branches and high height of new energy grid-connected lines, manual handheld detection is not suitable for fault diagnosis of these lines. Furthermore, if the line is icy due to weather conditions or has other impurities on its surface, the aforementioned line fault diagnosis device may make a misjudgment, causing unnecessary trouble for the subsequent use of the new energy grid-connected line. Summary of the Invention

[0009] Furthermore, a gear E is provided at the top of the driven shaft; the gear E meshes with and is connected to the gear D; a gear F is provided at the bottom of the driven shaft; a cleaning ring is provided at the bottom of the sliding block; the cleaning ring has a circular ring structure; a cleaning rotating ring is provided inside the cleaning ring; the cleaning rotating ring has a circular ring structure; a toothed ring B is provided on the outer circumference of the cleaning rotating ring; the toothed ring B meshes with and is connected to the gear F; a push rod is provided at the center of the outer side of the sliding block; the push rod has a rectangular structure.

[0010] Furthermore, one end of spring A is embedded in the outer side of the sliding block; the other end of spring A is embedded in the inner outer side of the sliding groove; a crushing component is provided on the outer side of the mounting plate; a force-bearing groove is formed on the outer side of the crushing component; the force-bearing groove has a trapezoidal structure; a crushing plate is provided at the bottom of the crushing component; a baffle is provided at the top of the crushing component; the baffle has a rectangular structure; one end of spring B is embedded in the bottom of the baffle; the other end of spring B is embedded in the top of the mounting plate.

[0011] Furthermore, this includes the following steps:

[0012] 1. The motor drives the drive shaft and bevel gear A to rotate, so that bevel gear A, in the action of meshing with bevel gear C, drives the front shaft and synchronous pulley A to rotate;

[0013] 2. Synchronous pulley A drives synchronous pulley B and the connecting shaft located on the front left side to rotate under the action of the synchronous belt, so that the connecting shaft drives the connecting shaft located on the front right side to rotate under the left and right sides of gear C.

[0014] Third, through the action of the synchronous pulley C and the synchronous belt, the two connecting shafts at these two points drive the two connecting shafts on the rear to rotate, so that the four connecting shafts drive the moving shaft and the moving wheel to rotate, and the moving wheel drives the device to move along the line;

[0015] IV. During the rotation of the drive shaft, it will drive the detection ring and detection probe to rotate under the meshing action of gear A and gear ring A, so that the detection probe can detect the new energy grid-connected line by rotating and diagnose whether there is a fault in the grid-connected line.

[0016] Beneficial effects

[0017] I. This invention uses a motor to drive a drive shaft and bevel gear A to rotate. Bevel gear A, meshing with bevel gear C, drives the front axle and synchronous pulley A to rotate. This, in turn, drives synchronous pulley B and the connecting shaft located on the left front side under the action of a synchronous belt. This connecting shaft, driven by gear C, drives the connecting shaft located on the right front side to rotate. These two connecting shafts, under the action of synchronous pulley C and the synchronous belt, drive the two connecting shafts on the rear side to rotate. These four connecting shafts drive the moving shaft and moving wheels to rotate. The moving wheels then move the device along the line. Simultaneously, during the rotation of the drive shaft, gear A and gear ring A mesh, drive the detection ring and detection probe to rotate. The detection probe, through rotation, detects the new energy grid-connected line and diagnoses whether there are faults in the grid-connected line. This allows the diagnostic device to move autonomously along the new energy grid-connected line for diagnosis. The device is equipped with a separate power drive unit, which can be installed on each branch line. It does not require manual handheld diagnostic testing and is not affected by multiple branches or high heights of the line, making it suitable for diagnosing faults in multi-branch new energy grid-connected lines.

[0018] II. In this invention, when the detection ring drives the detection probe to rotate and perform fault detection on the line, the detection ring will drive the transmission shaft and bevel gear B to rotate under the action of meshing gear A and gear B. Bevel gear B, in turn, drives the vertical shaft and gear D to rotate under the action of meshing with bevel gear D. Gear D, being an elliptical gear, drives gear E to rotate while providing force to move the sliding block outward along the slide groove. This causes the cleaning ring to move back and forth along the new energy grid-connected line, allowing the cleaning ring and the cleaning rotating ring to cooperate in removing impurities or ice layers on the line. This prevents the presence of impurities or ice layers on the line from affecting the detection probe's diagnosis of line faults and prevents misjudgment.

[0019] Third, during the sliding of the sliding block along the groove, gear E will also drive the driven shaft and gear F to rotate under the action of meshing with gear D. Gear F will drive the cleaning ring to rotate under the action of meshing with gear ring B. The cleaning ring can remove ice or impurities on the line more fully and quickly through the rotation and the back and forth movement of the cleaning ring.

[0020] Fourth, when the sliding block moves back and forth along the slide groove, the sliding block will drive the push rod to push the inclined surface of the force groove, so that the force groove is affected by the inclined surface being pushed and the crushed parts and crushing plate will descend, so that the crushing plate can make up-and-down reciprocating contact with the line, so that the crushing plate can knock and break the ice layer on the line, which is beneficial to the subsequent cleaning of the ice layer by the cleaning ring.

Detailed Implementation

[0034] To make the objectives, solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present invention.

[0035] Example: Please refer to Figures 1 to 8 As shown:

[0036] This invention provides a fault diagnosis device and method for multi-branch renewable energy grid-connected lines, comprising: a main body 1, with movable shafts 101 arranged on the left and right sides of the main body 1; movable wheels 102 arranged on the outer circumference of the movable shafts 101; a motor 103 arranged on the rear bottom side of the main body 1; a drive shaft 104 arranged at the center of the bottom of the main body 1; the drive shaft 104 has a cylindrical structure; a bevel gear A105 is arranged at the front end of the drive shaft 104; a gear A106 is arranged at the center of the drive shaft 104; a detection ring 107 is arranged inside the main body 1; the circumference of the detection ring 107... A gear ring A108 is provided on the outer wall; the gear ring A108 meshes with and is connected to the gear A106; a detection probe 109 is provided on the inner circumference of the detection ring 107; a drive shaft 1010 is provided on the top of the main body 1; the drive shaft 1010 has a cylindrical structure; bevel gears B1011 are provided at both ends of the drive shaft 1010; a gear B1012 is provided at the center of the drive shaft 1010; the gear B1012 meshes with and is connected to the gear ring A108; a front axle 1013 is provided at the bottom front side of the main body 1; mounting plates 2 are provided on the front and rear sides of the top of the main body 1.

[0037] The front axle 1013 has a bevel gear C 1014 at its top, which meshes with bevel gear A 105. A synchronous pulley A 1015 is located at the bottom of the front axle 1013. A connecting shaft 1016 is located at the bottom of the main body 1. The connecting shaft 1016 is cylindrical and its top end connects to the bottom end of the moving shaft 101. A synchronous pulley B 1017 is located on the connecting shaft 1016 at the front left end. The synchronous pulley B 1017 is connected to the synchronous pulley A 1015 via a synchronous belt. A synchronous pulley C 1018 is located on the outer circumference of the connecting shaft 1016. Adjacent synchronous pulleys C 1018 are connected by a synchronous belt. Gears C 1019 are located at the bottom ends of the two connecting shafts 1016 at the front. The two gears C 1019 mesh with each other.

[0038] Motor 103 drives drive shaft 104 and bevel gear A 105 to rotate. Bevel gear A 105, meshing with bevel gear C 1014, drives front shaft 1013 and synchronous pulley A 1015 to rotate. This, in turn, drives synchronous pulley B 1017 and connecting shaft 1016 located on the front left side to rotate under the action of synchronous belt. This, in turn, drives connecting shaft 1016 located on the front right side to rotate under the left and right influence of gear C 1019. These two connecting shafts 1016 then rotate around synchronous pulley C 1017. Under the action of the timing belt and the 18, the two connecting shafts 1016 on the rear side are driven to rotate, which in turn drives the moving shaft 101 and the moving wheel 102 to rotate. The moving wheel 102 drives the device to move along the line. At the same time, during the rotation of the drive shaft 104, the detection ring 107 and the detection probe 109 will rotate under the action of the meshing of the gear A106 and the gear ring A108. The detection probe 109 will then detect the new energy grid connection line by rotating and diagnose whether there is a fault in the grid connection line.

[0039] The mounting plate 2 has a vertical shaft 201 on its top inner side, which is cylindrical. A bevel gear D202 is mounted on the top of the vertical shaft 201 and meshes with a bevel gear B1011. A gear D203, an elliptical gear, is mounted on the outer circumference of the vertical shaft 201. A sliding groove 204, rectangular in shape, is opened on the outer top of the mounting plate 2. A sliding block 205 is located inside the sliding groove 204. A driven shaft 206, cylindrical in shape, is located inside the sliding block 205 and meshes with gear D203. A gear F208 is located at the bottom of the driven shaft 206. A cleaning ring 209, an annular structure, is located at the bottom of the sliding block 205.

[0040] When the detection ring 107 drives the detection probe 109 to rotate and perform fault detection on the circuit, the detection ring 107, under the action of the meshing of the gear ring A108 and the gear B1012, drives the drive shaft 1010 and the bevel gear B1011 to rotate. The bevel gear B1011, under the action of meshing with the bevel gear D202, drives the vertical shaft 201 and the gear D203 to rotate. The gear D203, utilizing its elliptical gear characteristics, drives the gear E207 to rotate while simultaneously providing force to move the sliding block 205 outward along the slide groove 204, causing the cleaning ring 209 to move along the new energy... The grid-connected line moves back and forth, causing the cleaning ring 209 and the cleaning rotating ring 2010 to slide and remove impurities or ice on the line. At the same time, as the sliding block 205 slides along the sliding groove 204, the gear E207 will also drive the driven shaft 206 and the gear F208 to rotate under the action of meshing with the gear D203. The gear F208 will drive the cleaning rotating ring 2010 to rotate under the action of meshing with the gear ring B2011. The cleaning rotating ring 2010 improves the efficiency and quality of removing impurities or ice by rotating and cooperating with the back and forth movement of the cleaning ring 209.

[0041] In another embodiment, a roller can be provided on the surface where the sliding block 205 contacts the groove 204. The roller can reduce the friction between the sliding block 205 and the groove 204, making the sliding block 205 move more smoothly.

[0042] The cleaning ring 209 includes a cleaning rotating ring 2010 inside; the cleaning rotating ring 2010 has a circular structure; a toothed ring B2011 is provided on the outer circumference of the cleaning rotating ring 2010; the toothed ring B2011 meshes with and is connected to the gear F208; a push rod 2012 is provided at the center of the outer side of the sliding block 205; the push rod 2012 has a rectangular structure; one end of a spring A2013 is embedded in the outer side of the sliding block 205; the other end of the spring A2013 is embedded in the sliding block 205. The inner and outer sides of the groove 204; the outer side of the mounting plate 2 is provided with a crushing component 2014; the outer side of the crushing component 2014 is provided with a force-bearing groove 2015; the force-bearing groove 2015 is a trapezoidal structure; the bottom of the crushing component 2014 is provided with a crushing plate 2016; the top of the crushing component 2014 is provided with a baffle 2017; the baffle 2017 is a rectangular structure; one end of the spring B2018 is embedded in the bottom of the baffle 2017; the other end of the spring B2018 is embedded in the top of the mounting plate 2;

[0043] When the sliding block 205 moves back and forth along the slide groove 204, the sliding block 205 will drive the push rod 2012 to push the inclined surface of the force groove 2015, so that the force groove 2015 is pushed by the inclined surface, causing the crushing part 2014 and the crushing plate 2016 to descend, so that the crushing plate 2016 can make up-down reciprocating contact with the line, so that the crushing plate 2016 can knock and break the ice layer on the line, making it easier to remove the ice layer.

[0044] This includes the following steps:

[0045] 1. The drive shaft 104 and bevel gear A 105 are rotated by the motor 103, so that the bevel gear A 105 drives the front shaft 1013 and the synchronous pulley A 1015 to rotate under the action of meshing with the bevel gear C 1014.

[0046] Second, under the action of the timing belt, the timing pulley A1015 drives the timing pulley B1017 and the connecting shaft 1016 located at the front left end to rotate, so that the connecting shaft 1016 drives the connecting shaft 1016 located at the front right end to rotate under the left and right of the gear C1019.

[0047] Third, through the action of the synchronous pulley C1018 and the synchronous belt, the two connecting shafts 1016 at these two locations drive the two connecting shafts 1016 on the rear side to rotate, so that the four connecting shafts 1016 drive the moving shaft 101 and the moving pulley 102 to rotate, so that the moving pulley 102 drives the device to move along the line;

[0048] Fourth, during the rotation of the drive shaft 104, it will drive the detection ring 107 and the detection probe 109 to rotate under the action of the meshing of the gear A106 and the gear ring A108, so that the detection probe 109 can detect the new energy grid connection line by rotating and diagnose whether there is a fault in the grid connection line.

[0049] The specific usage and function of this embodiment are as follows: In use, the motor 103 first drives the drive shaft 104 and bevel gear A 105 to rotate. Bevel gear A 105, meshing with bevel gear C 1014, drives the front shaft 1013 and synchronous pulley A 1015 to rotate. This, in turn, drives synchronous pulley B 1017 and the connecting shaft 1016 located on the front left side to rotate under the action of the synchronous belt. This causes the connecting shaft 1016 located on the front right side to rotate under the left and right downward movement of gear C 1019. This causes the two connecting shafts to... Under the action of the synchronous pulley C1018 and the synchronous belt, 1016 drives the two connecting shafts 1016 on the rear side to rotate, which in turn drives the moving shaft 101 and the moving wheel 102 to rotate. The moving wheel 102 then drives the device to move along the line. At the same time, during the rotation of the drive shaft 104, the meshing of the gear A106 and the gear ring A108 will drive the detection ring 107 and the detection probe 109 to rotate, so that the detection probe 109 can detect the new energy grid connection line by rotating and diagnose whether there is a fault in the grid connection line.

[0050] When the detection ring 107 drives the detection probe 109 to rotate and perform fault detection on the line, the detection ring 107, under the action of the meshing of the gear ring A108 and gear B1012, drives the drive shaft 1010 and bevel gear B1011 to rotate. Bevel gear B1011, in turn, meshes with bevel gear D202, driving the vertical shaft 201 and gear D203 to rotate. Gear D203, being an elliptical gear, drives gear E207 to rotate, simultaneously providing force to move the sliding block 205 outward along the groove 204. This causes the cleaning ring 209 to reciprocate along the new energy grid-connected line, allowing the cleaning ring 209 and the cleaning rotating ring 2010 to slide and remove impurities or ice from the line, facilitating fault diagnosis by the detection probe 109. Simultaneously, the sliding block 205 moves along the groove 204... 4. During the sliding process, gear E207 will also drive the driven shaft 206 and gear F208 to rotate under the action of meshing with gear D203. Gear F208 will drive the cleaning ring 2010 to rotate under the action of meshing with gear ring B2011. The cleaning ring 2010 will improve the efficiency and quality of removing impurities or ice by rotating and moving back and forth with the cleaning ring 209. Moreover, when the sliding block 205 moves back and forth along the slide groove 204, the sliding block 205 will drive the push rod 2012 to push the inclined surface of the force groove 2015. The force groove 2015 will be driven by the inclined surface to move the crushing part 2014 and the crushing plate 2016 down. The crushing plate 2016 will make reciprocating contact with the line, and the crushing plate 2016 will break the ice on the line by knocking it, which will facilitate the removal of the ice.
