Description

Technical Field

[0001] This invention application relates to the field of equipment testing technology, specifically to a surround imaging testing device for power transmission and transformation equipment. Background Technology

[0002] In power system operation and maintenance, visual inspection, defect identification, and condition monitoring of transmission and transformation equipment are crucial for ensuring the safe and stable operation of the power grid. Currently, the inspection of various outdoor transmission and transformation equipment, such as insulators, circuit breakers, and instrument transformers, mostly relies on close-range manual observation, handheld equipment photography, or traditional track-mounted imaging devices for surround data collection.

[0003] The patent with announcement number CN221351258U discloses an X-ray digital imaging inspection fixture for power transmission and transformation equipment. Its working principle is as follows: through the cooperation of the arc-shaped bracket and the arc-shaped arm, the X-ray equipment and the imaging plate are driven by the meshing of the drive gear and the arc-shaped rack to move along the arc-shaped track, so as to realize the circumferential inspection of the equipment under test. The orientation and height of the device can be adjusted by the telescopic arm, the support arm and the support frame.

[0004] Although the above solution achieves surround imaging detection and multi-angle position adjustment of power transmission and transformation equipment, it still has the following problems: the overall structure is an open arc shape, which cannot form a 360-degree fully encircling closed track; the arc arm is not effectively supported at the gap of the arc support, and it is prone to jumping and deviating during operation, resulting in insufficient imaging accuracy and operational stability. Summary of the Invention

[0005] To address the aforementioned issues, a surround imaging detection device for power transmission and transformation equipment is provided. By employing a layered structure that combines notch opening and closing, segmented splicing, and track closure, and by using snap-fit ​​concentric constraints to ensure the coaxiality of the toothed ring and the track, the device significantly improves the stability and detection accuracy of the surround imaging motion.

[0006] To address the problems of existing technologies, this invention provides a surround imaging detection device for power transmission and transformation equipment, comprising an imaging unit, a fixed support ring with a notch, a closed toothed ring unit, a closed track unit, and a drive unit. The toothed ring unit includes a main toothed ring with a notch, a movable supplementary tooth segment, and a connecting assembly for connecting the main toothed ring and the supplementary tooth segment. The supplementary tooth segment can be spliced ​​with the main toothed ring to form a complete toothed ring. The imaging unit is mounted on the main toothed ring. The closed track unit includes multiple limiting tracks that can rotate around the center of the fixed support ring. These limiting tracks rotate to fill the notch in the fixed support ring to form a continuous track and engage with the supplementary tooth segment to ensure that the supplementary tooth segment is concentric with the main toothed ring. The drive unit meshes with the complete toothed ring and drives the imaging unit to perform a surround motion along the continuous track.

[0007] Preferably, there are two toothed segments. The two toothed segments are initially located on both sides of the notch of the fixed support ring. After the fixed support ring is fitted, the two toothed segments move to the notch of the main toothed ring to complete the splicing.

[0008] Preferably, there are two limiting rails, which rotate in opposite directions to close the notch of the fixed support ring.

[0009] Preferably, the limiting track is provided with an annular protrusion, and the main tooth ring and the supplementary tooth section are both provided with a groove that matches the annular protrusion.

[0010] Preferably, the closed toothed ring unit further includes two transfer components, both of which are slidably disposed on the fixed support ring, and the transfer components are used to transfer the toothed section.

[0011] Preferably, the transfer assembly includes a sliding seat, a linear actuator, and a first magnetic block; the sliding seat is slidably disposed on the fixed support ring around the center of the fixed support ring; the linear actuator is used to drive the tooth-filling segment to move; and the first magnetic block is used to attract the tooth-filling segment.

[0012] Preferably, the closed toothed ring unit further includes a docking assembly for fixing the two transfer assemblies together.

[0013] Preferably, the closed toothed ring unit further includes two locking components, which are used to lock the position of the sliding seat.

[0014] Preferably, a driving component is provided between the two limiting tracks, the driving component being used to drive the two limiting tracks to rotate in opposite directions.

[0015] Preferably, the drive unit includes a drive gear and a second rotary driver; the drive gear meshes with a complete ring gear; the second rotary driver is used to provide power for the rotation of the drive gear.

[0016] The advantages of this invention application compared to the prior art are: 1. This invention comprises a fixed support ring, a toothed ring unit, a closed track unit, and a drive unit. The fixed support ring and the main toothed ring are engaged through an open notch, enabling the device to be mounted on installed power transmission and transformation equipment without disassembly. The supplementary tooth segment and the main toothed ring are mated together to form a complete toothed ring, providing a continuous meshing basis for transmission. The limiting track engages with the fixed support ring and the supplementary tooth segment, and the closed notch forms a continuous track, ensuring the overall concentricity of the toothed ring. The drive unit engages with the complete toothed ring and the continuous track, driving the imaging unit to complete stable circumferential detection. Each component engages in reverse order to achieve rapid reset. The invention employs a layered structure with open and closed notches, segmented splicing, and closed track, and ensures the coaxiality of the toothed ring and track through snap-fit ​​concentricity constraints, thereby significantly improving the stability and detection accuracy of the circumferential imaging motion.

[0017] 2. This invention application sets up two tooth-filling segments, which cooperate with the fixed support ring and the main tooth ring. Initially, the notch is kept open to achieve lateral fitting of the device. After fitting and positioning, it moves synchronously along the guide path and docks with the main tooth ring. With the cooperation of the connecting components, the main tooth ring is completed into a complete closed tooth ring, providing a stable meshing basis for drive transmission. The use of two short tooth-filling segments for segmented tooth filling results in a shorter travel distance, more stable positioning, and higher splicing accuracy compared to a single long tooth-filling segment.

[0018] 3. This invention application sets two limiting tracks, which cooperate with the inner track groove of the fixed support ring. Initially, they avoid the gap to ensure the device can be smoothly installed. After being installed in place, they rotate synchronously in opposite directions around the center of the fixed support ring and connect and close at the gap, forming a continuous and complete ring track. This provides stable support and guidance for the imaging unit. The overall cooperation makes the track closing stroke shorter, the action faster, the docking more stable, and the force more symmetrical, significantly improving the track closing accuracy and the stability of the device operation.

[0030] To further understand the features, technical means, and specific objectives and functions achieved by this invention application, the invention application will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1 to 10The diagram shows a surround imaging detection device for power transmission and transformation equipment, comprising an imaging unit 1, a fixed support ring 2 with a notch, a closed toothed ring unit 3, a closed track unit 4, and a drive unit 5. The closed toothed ring unit 3 includes a main toothed ring 31 with a notch, a movable supplementary tooth segment 32, and a connecting assembly 33 for connecting the main toothed ring 31 and the supplementary tooth segment 32. The supplementary tooth segment 32 can be spliced ​​with the main toothed ring 31 to form a complete toothed ring. The imaging unit 1 is mounted on the main toothed ring 31. The closed track unit 4 includes multiple limiting tracks 41 that can rotate around the center of the fixed support ring 2. The multiple limiting tracks 41 fill the notch of the fixed support ring 2 by rotation to form a continuous track and engage with the supplementary tooth segment 32 to ensure that the supplementary tooth segment 32 is concentric with the main toothed ring 31. The drive unit 5 meshes with the complete toothed ring and drives the imaging unit 1 to perform surround motion along the continuous track.

[0032] In the initial state, both the fixed support ring 2 and the main gear ring 31 have open notches, allowing the device to be directly fitted onto the outside of the installed power transmission and transformation equipment from the side without disassembling the equipment. After being fitted in place, the tooth-filling segment 32 moves along a preset path to the notch position of the main gear ring 31 and, under the action of the connecting component 33, docks with the main gear ring 31 to form a continuous and complete gear ring. Subsequently, multiple limiting tracks 41 rotate synchronously around the center of the fixed support ring 2, gradually filling the notch of the fixed support ring 2 to form a continuous closed track; the limiting tracks 41 also engage with the tooth-filling segment 32, constraining the radial position of the tooth-filling segment 32 and ensuring that it remains concentric with the main gear ring 31; finally, the drive unit 5 meshes with the complete gear ring, driving the imaging unit 1 mounted on the main gear ring 31 to move stably around the continuous track, completing the 360-degree imaging detection of the power transmission and transformation equipment. After the detection is completed, the components are reset in reverse order, and the device can be quickly removed from the equipment. It adopts a layered structure that combines notch opening and closing, segmented splicing and track closure, and ensures the coaxiality of the toothed ring and the track through snap-fit ​​concentric constraints, thereby significantly improving the stability of the surround imaging motion and the detection accuracy.

[0033] Reference Figure 2 , Figure 3 and Figure 4 As shown: There are two toothed segments 32. The two toothed segments 32 are initially located on both sides of the notch of the fixed support ring 2. After the fixed support ring 2 is fitted, the two toothed segments 32 move to the notch of the main toothed ring 31 to complete the splicing.

[0034] Initially, the two tooth-filling segments 32 are positioned on the left and right sides of the notch in the fixed support ring 2, keeping both the fixed support ring 2 and the main toothed ring 31 open. This facilitates the device being fitted laterally onto the outside of the power transmission and transformation equipment to be tested. After the fixed support ring 2 is fitted and positioned, the two tooth-filling segments 32 move synchronously along the guide path of the fixed support ring 2 towards the notch in the main toothed ring 31. They eventually mate with both ends of the main toothed ring 31 and connect under the action of the connecting component 33, together completing the main toothed ring 31 into a continuous, closed, complete toothed ring, providing a stable meshing foundation for subsequent drive transmission. Compared to a single long tooth-filling segment 32, using two short tooth-filling segments 32 for segmented tooth filling results in a shorter travel distance, more stable positioning, and higher splicing accuracy.

[0035] Reference Figure 2 , Figure 3 and Figure 4 As shown: There are two limiting rails 41, and the two limiting rails 41 rotate in opposite directions to close the notch of the fixed support ring 2.

[0036] Two limiting tracks 41 are respectively assembled in the inner track grooves of the fixed support ring 2, initially avoiding the notch of the fixed support ring 2, allowing the device to be smoothly fitted onto the equipment to be tested. After being fitted into place, the two limiting tracks 41 rotate synchronously in opposite directions around the center of the fixed support ring 2, and mate with each other at the notch of the fixed support ring 2, completely closing the notch and forming a continuous and complete circular track, providing continuous support and guidance for the imaging unit 1. The synchronous rotation and closure of the dual limiting tracks 41 in opposite directions results in a shorter closing stroke, faster action, smoother track docking, and more symmetrical overall force distribution, effectively improving the track closure accuracy and operational stability.

[0037] Reference Figure 4 As shown: The limiting track 41 is provided with an annular protrusion 411, and the main tooth ring 31 and the supplementary tooth section 32 are both provided with a slot 311 that matches the annular protrusion 411.

[0038] An annular protrusion 411 is integrally formed on the outer circumferential surface of the limiting track 41. The inner circumferential surfaces of the main gear ring 31 and the supplementary gear segment 32 are both machined with annular grooves 311 that match the shape of the annular protrusion 411. When the limiting track 41 rotates around the center of the fixed support ring 2 and closes the notch, the annular protrusion 411 on the limiting track 41 simultaneously engages with the corresponding grooves 311 of the main gear ring 31 and the supplementary gear segment 32, forming a radial limiting fit. This constrains the radial position of the main gear ring 31 and the supplementary gear segment 32, preventing radial movement and eccentricity. Through the engagement of the annular protrusion 411 and the grooves 311, the concentricity of the gear ring and the limiting track 41 is reliably ensured, significantly reducing transmission runout and improving the positioning accuracy and motion stability of the surround imaging.

[0039] Reference Figure 2 and Figure 5 As shown: The closed toothed ring unit 3 also includes two transfer components 34, both of which are slidably disposed on the fixed support ring 2. The transfer components 34 are used to transfer the toothed section 32.

[0040] Both transfer components 34 are slidably mounted on the fixed support ring 2, each corresponding to a toothed segment 32. After the fixed support ring 2 is fitted onto the power transmission and transformation equipment to be tested, the two transfer components 34 slide synchronously along the guide path of the fixed support ring 2, smoothly transferring the toothed segment 32 to the preset docking position of the notch in the main toothed ring 31, providing stable support and precise guidance for the reliable splicing of the toothed segment 32 and the main toothed ring 31. By using the transfer components 34 to independently support and transfer the toothed segment 32, the consistency of the splicing position and posture of the toothed ring is effectively ensured, significantly improving the accuracy and stability of repeated assembly of the device.

[0041] Reference Figure 5 and Figure 6 As shown: The transfer assembly 34 includes a sliding seat 341, a linear actuator 342, and a first magnetic block 343; the sliding seat 341 is slidably disposed on the fixed support ring 2 around the center of the fixed support ring 2; the linear actuator 342 is used to drive the tooth-filling segment 32 to move; the first magnetic block 343 is used to attract the tooth-filling segment 32.

[0042] The sliding seat 341 is slidably mounted on the fixed support ring 2 with the center of the ring as its center. The linear actuator 342 and the first magnetic block 343 are both mounted on the sliding seat 341. The first magnetic block 343 is an electromagnet, and its attraction is controlled by energizing it. Initially, the first magnetic block 343 is energized to attract the tooth section 32, stably placing it within the sliding seat 341. After the sliding seat 341 slides along the fixed support ring 2 to the notch position, the linear actuator 342 extends, pushing the tooth section 32 towards the main tooth ring 31 via the first magnetic block 343 to complete the connection. After the tooth section 32 and the main tooth ring 31 are connected, the first magnetic block 343 is de-energized and demagnetized, the linear actuator 342 retracts, and the first magnetic block 343 separates from the tooth section 32. The magnetic attraction combined with the linear drive achieves reliable clamping and precise pushing of the tooth section 32, improving the automation level and assembly stability of the tooth ring splicing.

[0043] Reference Figure 2 and Figure 7 As shown: The closed toothed ring unit 3 further includes a docking component 35, which is used to fix the two transfer components 34.

[0044] Specifically, the docking assembly 35 includes two docking plates 351, which are respectively disposed at opposite ends of the two sliding seats 341. Each docking plate 351 is provided with a second magnetic block 352, and the two second magnetic blocks 352 attract each other. One docking plate 351 is provided with a positioning rod 353, and the other docking plate 351 has a corresponding insertion hole. When the two sliding seats 341 abut against each other, the positioning rod 353 is inserted into the insertion hole to prevent misalignment, and the two second magnetic blocks 352 attract each other, so that the abutting ends of the two sliding seats 341 are connected.

[0045] When the two transfer components 34 move to the notch of the main gear ring 31 and approach each other, the docking plates 351, respectively located at the opposite ends of the two sliding seats 341, abut against each other. A positioning rod 353 on one docking plate 351 inserts into the corresponding hole on the other docking plate 351, achieving mechanical positioning to prevent misalignment. Simultaneously, the second magnetic blocks 352 on the two docking plates 351 attract each other, firmly connecting the abutting ends of the two transfer components 34, forming an integral positioning structure. This provides positioning assurance for the precise docking of the tooth section 32 and the main gear ring 31. The positioning rod 353 and the magnetic attraction work together for dual positioning, ensuring that the transfer components 34 dock without misalignment or offset, improving the accuracy of the splicing position, and ensuring the continuity and integrity of the gear ring.

[0046] Reference Figure 2 and Figure 8 As shown: The closed toothed ring unit 3 also includes two locking components 36, which are used to lock the position of the sliding seat 341.

[0047] Specifically, the locking assembly 36 includes a connecting plate 361 and a locking bolt 362. The connecting plate 361 has a threaded hole, and the locking bolt 362 is threadedly connected to the threaded hole. When the sliding seat 341 moves to the preset position, the locking bolt 362 is rotated to connect with the fixed support ring 2, thereby locking the position of the sliding seat 341.

[0048] In the initial state, the locking bolt 362 is tightened and fixedly connected to the fixed support ring 2, locking the sliding seat 341 to the open side of the fixed support ring 2 to prevent accidental slippage. After the fixed support ring 2 is fitted onto the device to be tested, the locking bolt 362 is loosened to release the lock, and the sliding seat 341 can slide normally along the fixed support ring 2. After the two sliding seats 341 move to the notch and abut against each other, the locking bolt 362 is tightened again to fix the locking bolt 362 to the fixed support ring 2, locking the position of the sliding seat 341 and preventing the sliding seat 341 from shaking or displacing when driving the tooth section 32. The locking assembly 36 locks the position of the sliding seat 341, effectively preventing slippage and misalignment, and improving the overall rigidity and operational stability of the tooth ring splicing and transmission process.

[0049] Reference Figure 2 and Figure 9 As shown: A drive assembly 42 is provided between the two limiting rails 41, and the drive assembly 42 is used to drive the two limiting rails 41 to rotate in opposite directions.

[0050] Specifically, the drive assembly 42 includes two drive bars 421, a drive wheel 422, and a first rotary driver 423. The two drive bars 421 are respectively connected to two limit rails 41 and are arranged parallel to each other. The drive wheel 422 is located between the two drive bars 421 and is connected to the two drive bars 421 in a transmission manner. The first rotary driver 423 provides the power for the drive wheel 422 to rotate.

[0051] After the toothed section 32 and the main toothed ring 31 are spliced ​​together, the drive assembly 42 starts working. The first rotary driver 423 in the drive assembly 42 starts and drives the drive wheel 422 to rotate. The drive wheel 422 simultaneously drives the two transmission bars 421 to move in opposite directions in a straight line, thereby driving the two limiting rails 41 to rotate synchronously in opposite directions around the center of the fixed support ring 2, quickly completing the track closure and docking. The single drive wheel 422 synchronously drives the two transmission bars 421 to achieve opposite rotation, concentrating power and synchronizing actions, effectively improving the track closure efficiency.

[0052] Reference Figure 2 and Figure 10 As shown: The drive unit 5 includes a drive gear 51 and a second rotary driver 52; the drive gear 51 meshes with a complete gear ring; the second rotary driver 52 is used to provide power for the rotation of the drive gear 51.

[0053] When the supplementary tooth segment 32 and the main toothed ring 31 are spliced ​​together to form a complete toothed ring, and the two limiting tracks 41 close to form a continuous circular track, the second rotary driver 52 is activated, driving the drive gear 51 to rotate. The drive gear 51 maintains meshing transmission with the complete toothed ring, thereby driving the imaging unit 1 to make a stable circular motion along the closed track, completing the 360-degree imaging detection of the power transmission and transformation equipment. The use of gear meshing transmission ensures stable and reliable power transmission, effectively guaranteeing the uniform and smooth movement of the imaging unit 1, and improving the clarity and continuity of the detected image.

[0054] The above embodiments only illustrate one or more implementation methods of this invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these all fall within the protection scope of this invention.
