Description

Technical Field

[0001] This invention belongs to the field of disconnector switch testing, specifically a disconnector switch output shaft rotation angle measurement system for online monitoring. Background Technology

[0002] A disconnecting switch is a component used in industrial equipment to connect and disconnect circuits. In existing technology, a disconnecting switch consists of components such as a pin, bearing, and spring. The rotation of the pin connects or disconnects the circuit, while the elasticity of the spring enables the pin to rotate and reset. In existing technology, online measurement of the disconnecting switch's rotation angle is particularly important, as the results directly determine the accuracy of the disconnecting switch in practical applications. In practice, disconnecting switch rotation angle measurement involves measuring the spring inside the disconnecting switch and calculating the rotation angle based on the measured data. Therefore, the measurement of the disconnecting switch's rotation angle is primarily achieved by measuring the spring, and the measurement results are transmitted in real time to a display screen for display, thus completing the measurement.

[0003] In the prior art, there are many measuring devices and methods for springs in disconnect switches. Among them, CN110082051B discloses an automatic spring detection device, including a detection table. Two vertically arranged support plates are fixedly connected to the upper end of the detection table. The two support plates are respectively located on both sides of the upper end of the detection table, and two vertically arranged movable plates are provided between the two support plates. T-shaped grooves are formed at opposite ends of the two movable plates. A set of T-shaped sliders is slidably connected inside each of the two T-shaped grooves. L-shaped rods are fixedly connected to the two ends of each set of two T-shaped sliders outside the T-shaped groove. The vertical ends of the two L-shaped rods are arranged oppositely. A vertically arranged bidirectional threaded rod is provided inside the T-shaped groove. Although the above patent… The automatic spring detection device is simple to operate and can protect the user from spring breakage and injury during detection. However, during the detection process, the bidirectional threaded rods at both ends cannot accurately control the distance the L-shaped rods move while being twisted. As a result, the corresponding L-shaped rods on the two bidirectional threaded rods are not on the same horizontal plane, leading to deviations in the spring force gauge's results and further causing errors in the spring diagnosis. Therefore, it is essential to design a disconnect switch output shaft rotation angle measurement system that can fix the spring to improve the detection results. Summary of the Invention

[0004] The purpose of this invention is to provide a system for measuring the rotation angle of the output shaft of a disconnecting switch for online monitoring, which solves the problems mentioned in the background art by setting up limiting and moving parts.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a disconnector output shaft rotation angle measurement system for online monitoring, comprising a diagnostic box, wherein multiple limiting components are installed inside the diagnostic box, and multiple moving components are installed inside the diagnostic box, the multiple moving components being distributed around the diagnostic box, a fixed plate being fixedly connected to the center of the internal cavity of the diagnostic box, and a mounting plate being fixedly connected to the fixed plate, the multiple moving components being slidably connected to the diagnostic box through corresponding mounting slots, the multiple limiting components being distributed on corresponding mounting plates and moving components, multiple second rotating rods being nested inside the mounting plate, each limiting component comprising a base plate and a mounting ring, a limiting opening being formed on the side of the mounting ring, a second limiting block being fixedly connected to the side of the mounting ring near the second rotating rod, and the end of the second limiting block away from the mounting ring being fixedly connected to the second rotating rod.

[0006] As a further aspect of the present invention: a drive motor is fixedly connected to the bottom of the diagnostic box, and a first rotating rod is fixedly connected to the output end of the drive motor. The end of the first rotating rod away from the drive motor is rotatably connected to the bottom end of the mounting plate. Multiple second rotating rods are nested inside the mounting plate. A first cylindrical gear is fixedly sleeved at the end of the second rotating rod located at the bottom end of the mounting plate, and a second cylindrical gear is fixedly sleeved at the end of the first rotating rod near the mounting plate. The second cylindrical gear meshes with the multiple first cylindrical gears.

[0007] As a further embodiment of the present invention: the end of the second rotating rod away from the first cylindrical gear passes through the base plate and is rotatably connected to the base plate; a second limiting block is fixedly connected to the side of the mounting ring near the second rotating rod; and the end of the second limiting block away from the mounting ring is fixedly connected to the second rotating rod.

[0008] As a further embodiment of the present invention: the second limiting block is an axisymmetric shape, and the second limiting block has grooves on both sides along the axis of symmetry.

[0009] As a further embodiment of the present invention, it also includes a support frame, which is placed on the ground. The bottom end of the diagnostic box is fixedly connected to the top end of the support frame. A sliding plate is installed on the diagnostic box, and the sliding plate is slidably connected to the diagnostic box through a limiting groove. An installation frame is fixedly connected to the upper left side of the support frame, and a display screen is installed inside the installation frame.

[0010] As a further embodiment of the present invention: a cylinder is installed inside the moving part, and a spring force gauge is fixedly connected to the end of the cylinder away from the pulling block. Both the cylinder and the spring force gauge are connected to the display screen. The base plate on the limiting member located inside the moving part is fixedly connected to one side of the spring force gauge. A first limiting block is installed inside the diagnostic box, and the limiting member fixedly connected to the spring force gauge is slidably connected to the first limiting block through a second rotating rod.

[0011] As a further embodiment of the present invention: a first latching block and a second latching block are fixedly connected to the moving part, and the position of the second latching block is closer to the diagnostic box than the position of the first latching block.

[0012] As a further embodiment of the present invention: all of the aforementioned limiting members are located on the same horizontal plane.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In the angle measurement system of the present invention, by setting a limiting component, the cylinder drives the movement of the limiting component, thereby realizing the stretching operation of the spring during the spring detection process. At the same time, the cylinder controls multiple limiting components to move synchronously, and the positions of the moving components are reasonably allocated inside the diagnostic box. Thus, while saving space, the diagnostic device can diagnose multiple springs simultaneously, thereby improving the efficiency of the diagnostic device in diagnosing springs to a certain extent. When the limiting component limits the spring, the drive motor drives the four limiting components on the mounting plate to rotate synchronously, thereby limiting the spring by the limiting component and effectively preventing the spring from dislodging from the limiting component, which facilitates the diagnostic operation of the diagnostic device on the spring. Meanwhile, a second limiting block is set inside the limiting component, and the second limiting block is symmetrically arranged about the horizontal axis of the limiting component. Grooves are set on both sides of the second limiting component, and the grooves are used to further limit the spring, solving the problem that the spring is prone to shaking in the annular mounting ring.

[0014] 2. The limiting component on the moving part slides on the first limiting component block, and the first limiting block limits the limiting component. This ensures that during the spring stretching process, the spring stretching path and the two corresponding limiting components are on the same horizontal plane. This improves the stretching process of the limiting component and reduces the error generated during the spring force gauge measurement. Furthermore, by ensuring the spring stretching process is on the same horizontal plane as the two limiting components, it facilitates the measurement of the spring stretching distance. This allows for the correlation between the spring's movement distance and the cylinder's movement distance, making it easier to determine the spring's movement distance and reducing errors in the spring distance determination process. This further improves the accuracy of the diagnostic device in diagnosing the spring.

[0015] 3. By setting up the diagnostic box, a sliding plate is installed inside the diagnostic box, and the sliding plate is slidably connected to the diagnostic box through a limiting groove. The limiting groove is used to achieve stability during the sliding process of the sliding plate. During the spring diagnosis process, moving the sliding plate closes the diagnostic box, thereby preventing the spring from popping out of the diagnostic box due to the elastic force generated by the spring itself during the stretching process. Due to the uncertainty of the direction of the spring elastic force, it is difficult to find the spring for testing, which reduces the diagnostic efficiency of the spring diagnosis process, and also has the disadvantage of causing injury to the testing personnel when the spring flies out.

[0016] 4. By setting a first locking block and a second locking block on the side of the moving part, the moving part is limited on the diagnostic box. At the same time, the setting of the first locking block and the second locking block can limit the moving part when the diagnostic device diagnoses the spring. Thus, during the process of the cylinder driving the spring to move, the distance of the spring movement can be observed by the extension and retraction of the cylinder, and the data on the spring force gauge can be observed. The pre-diagnosis of the spring can be achieved by using the cylinder and the spring force gauge, which solves the drawback of the existing technology where the observation data of the internal data of the diagnostic box is biased due to visual deviation.

[0028] 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.

When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element.

[0030] Please see Figures 1-10In this embodiment of the invention, a system for measuring the output shaft rotation angle of an isolating switch for online monitoring includes a diagnostic box 10 and a support frame 11. The support frame 11 is placed on the ground, and the bottom end of the diagnostic box 10 is fixedly connected to the top end of the support frame 11. A sliding plate 12 is installed on the diagnostic box 10, and the sliding plate 12 is slidably connected to the diagnostic box 10 through a limiting groove 121. The limiting groove 121 is used to achieve stability of the sliding plate 12 during the sliding process. During the spring diagnosis process, moving the sliding plate 12 closes the diagnostic box 10, thereby preventing the spring from popping out of the diagnostic box due to the elastic force generated by the spring itself during the stretching process. Due to the uncertainty of the direction of the spring's elastic force, it is difficult to find the detection spring. To address the drawbacks of reduced diagnostic efficiency during spring testing and the risk of injury to testing personnel during spring bounce, the support frame 11 has a mounting frame 20 fixedly connected to its upper left side. A display screen 21 is installed inside the mounting frame 20. The support frame 11 supports the display screen 21 and the diagnostic box 10, ensuring the stability of the diagnostic device during spring testing. A fixing plate 13 is fixedly connected to the center of the diagnostic box 10, and a mounting plate 131 is fixedly connected to the fixing plate 13, nested within the fixing plate 13. A drive motor 14 is fixedly connected to the bottom of the diagnostic box 10, and a first rotating rod 141 is fixedly connected to the output end of the drive motor 14. The motor 14 provides driving force to the first rotating rod 141, thereby driving the first rotating rod 141 to rotate using the drive motor 14. The end of the first rotating rod 141 away from the drive motor 14 is rotatably connected to the bottom end of the mounting plate 131. Multiple second rotating rods 401 are nested inside the mounting plate 131. A first cylindrical gear 15 is fixedly sleeved at the end of the second rotating rod 401 located at the bottom end of the mounting plate 131. A second cylindrical gear 16 is fixedly sleeved at the end of the first rotating rod 141 near the mounting plate 131. The second cylindrical gear 16 meshes with the multiple first cylindrical gears 15. Multiple limiting members 40 and multiple moving parts 30 are installed inside the diagnostic box 10. Multiple movable parts 30 are distributed around the diagnostic box 10. Each movable part 30 is slidably connected to the diagnostic box 10 through a corresponding mounting slot. Multiple limiting parts 40 are distributed on the corresponding mounting plate 131 and movable parts 30. All limiting parts 40 are located on the same horizontal plane. By setting the limiting parts 40, the cylinder 31 drives the limiting parts 40 to move, thereby realizing the stretching operation of the spring during the spring testing process. At the same time, the cylinder 31 controls the synchronous movement of multiple limiting parts 40, and the positions of the movable parts 30 are reasonably allocated inside the diagnostic box. Thus, while saving space, the diagnostic device can diagnose multiple springs at the same time, thereby improving the efficiency of the diagnostic device in diagnosing springs to a certain extent.

[0031] The limiting member 40 includes a base plate 41 and a mounting ring 42. A limiting opening is provided on the side of the mounting ring 42. The end of the second rotating rod 401 away from the first cylindrical gear 15 passes through the base plate 41 and is rotatably connected to it. A second limiting block 421 is fixedly connected to the side of the mounting ring 42 near the second rotating rod 401. The end of the second limiting block 421 away from the mounting ring 42 is fixedly connected to the second rotating rod 401. When the limiting member 40 is used to limit the spring, the drive motor 14 drives the four limiting members 40 on the mounting plate 131 to rotate synchronously. The specific steps to achieve the limiting of the spring by the limiting member 40 are to effectively prevent the spring from disengaging from the limiting member 40, so as to facilitate the diagnostic operation of the spring by the diagnostic device. The second limiting block 421 is an axisymmetric figure. The second limiting block 421 has grooves on both sides along the axis of symmetry. At the same time, the second limiting block 421 is set inside the limiting member 40, and the second limiting block 421 is symmetrical about the horizontal axis of the limiting member 40. The second limiting block 421 has grooves on both sides. The grooves are used to further limit the spring and solve the problem that the spring is prone to shaking in the annular mounting ring 42.

[0032] The movable component 30 is fixedly connected to a pull block 301 at its end located outside the diagnostic box 10. A cylinder 31 is installed inside the movable component 30. The spring stretching process is achieved by using limiting components 40, ensuring that the two limiting components 40 are on the same horizontal plane. This facilitates the measurement of the spring stretching distance and correlates the spring's movement distance with the cylinder 31's movement distance, thus simplifying the determination of the spring's movement distance and reducing errors in the spring distance determination process. This further improves the accuracy of the diagnostic device in diagnosing the spring. A spring force gauge is fixedly connected to the end of the cylinder 31 furthest from the pull block 301. 32. Both the cylinder 31 and the spring balance 32 are connected to the display screen 21. The base plate 41 on the limiting member 40 located inside the moving part 30 is fixedly connected to one side of the spring balance 32. It should be noted that the mounting ring 42 does not contact the spring balance 32. A first limiting block 17 is installed inside the diagnostic box 10. The limiting member 40, which is fixedly connected to the spring balance 32, is slidably connected to the first limiting block 17 through the second rotating rod 401. The limiting member 40 on the moving part 30 is controlled to slide within the first limiting block 17, and the first limiting block 17 is used to limit the limiting member 40, thereby... During the spring stretching process achieved by the limiting member 40, the spring stretching path is kept on the same horizontal plane as the two corresponding limiting members 40. The spring is stretched by the lifting limiting member 40. The spring force gauge 32 measures the spring, reducing the error generated during the measurement process. A first locking block 302 and a second locking block 303 are fixedly connected to the moving member 30. The position of the second locking block 303 is closer to the diagnostic box 10 than the position of the first locking block 302. By setting the first locking block 302 and the second locking block 303 on the side of the moving member 30, the moving member 30 is positioned within the diagnostic box 10. The limiting position on the test chamber 10, along with the first locking block 302 and the second locking block 303, allows the second locking block 303 to limit the moving part 30 during the diagnostic device's diagnosis of the spring. This enables the observation of the spring's movement distance through the extension and retraction of the cylinder 31 as the cylinder 31 drives the spring, and also allows the observation of the data on the spring force gauge 32. By using the cylinder 31 and the spring force gauge 32, the pre-diagnosis of the spring can be achieved, solving the problem in the prior art where visual bias leads to data deviation when observing the data inside the diagnostic chamber 10.

[0033] The working principle of this invention is: First, when diagnosing a spring using a diagnostic device, pull the slide plate 12 to open the upper end of the diagnostic box 10. Place the spring to be diagnosed inside the diagnostic box 10 for diagnosis. During the diagnosis process, the slide plate 12 is positioned inside the diagnostic box 10 and is slidably connected to the diagnostic box 10 via a limiting groove 121. The limiting groove 121 ensures stability during the sliding process of the slide plate 12. During the spring diagnosis, moving the slide plate 12 closes the diagnostic box 10, thus preventing the spring from popping out of the diagnostic box due to its own elastic force during stretching. The uncertainty of the direction of the spring's elastic force makes it difficult to locate the spring, reducing the difficulty of testing. To improve diagnostic efficiency during spring testing and mitigate the risk of injury to testing personnel during spring bounce, a limiting element 40 on the mounting plate 131 and the limiting element 40 on the moving part 30 are used to limit the spring under test. Before the limiting element 40 clamps the spring, the pulling block 301 on the side of the diagnostic box 10 is pulled to control the sliding of the moving part 30 inside the diagnostic box 10. When the second locking block 303 on the moving part 30 engages with the diagnostic box 10, the pulling of the moving part 30 is stopped. By setting the first locking block 302 and the second locking block 303 on the side of the moving part 30, the moving part 30 is limited on the diagnostic box 10. At the same time, the setting of the first locking block 302 and the second locking block 303 can enable the diagnostic device to test the spring. During diagnosis, the second locking block 303 is used to limit the movement of the moving part 30. This allows for observation of the spring's movement distance via the extension and retraction of the cylinder 31, and also enables observation of the data on the spring force gauge 32. This method utilizes the cylinder 31 and spring force gauge 32 to achieve pre-diagnosis of the spring, solving the problem of visual bias leading to data inaccuracies when observing data inside the diagnostic box 10 in existing technologies. It should be noted that initially, when the second locking block 303 on the moving part 30 is engaged with the diagnostic box 10, the cylinder 31 is in an extended state, and the limiting member 40 on the moving part 30 is located inside the diagnostic box 10. At this time, the limiting member on the moving part 30... The limiting member 40, corresponding to the position on the mounting plate 131, limits the spring to be tested. First, one end of the spring is hooked onto the mounting ring 42 through the limiting port on the moving member 30. The installed spring contacts the groove on the side of the second limiting block 421 inside the limiting member 40. The second limiting block 421 is designed to facilitate the installation of the spring onto the mounting ring 42 from either side. The second limiting block 421 is set inside the limiting member 40 and is symmetrical about the horizontal axis of the limiting member 40. Grooves are provided on both sides of the second limiting block 421 to further limit the spring and solve the problem of the spring easily wobbling inside the annular mounting ring 42. Similarly,Multiple springs to be diagnosed are installed onto the corresponding limiting members 40 on the moving part 30. After the multiple springs to be diagnosed are installed, the other side of the spring to be diagnosed is sleeved onto the limiting member 40 on the mounting plate 131. It should be noted that, in the initial state, the limiting openings of the limiting members 40 on the moving part 30 and the corresponding limiting members 40 on the mounting plate 131 both face one end of the inner wall of the diagnostic box 10. At this time, the spring sleeved on the mounting plate 131 is initially limited by the arc-shaped inner wall of the mounting ring 42.

[0034] After multiple springs are installed in their corresponding positions, the drive motor 14 is started. Since the output end of the drive motor 14 is fixedly connected to the first rotating rod 141, the drive motor 14 can provide driving force to the first rotating rod 141. The first rotating rod 141 begins to rotate under the action of the drive motor 14. Since the second cylindrical gear 16 is fixedly sleeved on the first rotating rod 141, the rotation of the first rotating rod 141 can further drive the second cylindrical gear 16 to rotate. Since the second cylindrical gear 16 is meshed with multiple first cylindrical gears 15, the rotation of the second cylindrical gear 16 can drive multiple first cylindrical gears 15 to rotate. The cylindrical gear 15 rotates synchronously. Since the first cylindrical gear 15 is fixedly sleeved on the second rotating rod 401, and the first cylindrical gear 15 is rotatably connected to the mounting plate 131 via the corresponding second rotating rod 401, and the end of the second rotating rod 401 passing through the base plate 41 is fixedly connected to the mounting ring 42, the rotation of the second rotating rod 401 can further drive the mounting ring 42 to rotate. The drive motor 14 controls the second rotating rod 401 to rotate half a turn, thereby causing the mounting ring 42 to rotate half a turn under the action of the second rotating rod 401. Because multiple second rotating rods 401 rotate synchronously with the first rotating rod 141... As the second rotating rod 401 rotates, the multiple mounting rings 42 rotate half a turn. Since, initially, the limiting members 40 on the moving part 30 and the corresponding limiting openings on the mounting plate 131 both face one end of the inner wall of the diagnostic box 10, after the mounting rings 42 on the mounting plate 131 rotate half a turn, the limiting openings of the mounting rings 42 on the moving part 30 and the mounting rings 42 on the mounting plate 131 face different directions. During the spring tensioning process controlled by the cylinder 31, this provides a force in the opposite direction to the spring, thereby achieving spring tension while preventing the spring from contacting the internal limiting members of the diagnostic device. To address the drawbacks of the detachment of springs, the drive motor 14 drives the four limiting members 40 on the mounting plate 131 to rotate synchronously, thereby limiting the springs by the limiting members 40. This facilitates the diagnostic operation of the diagnostic device on the springs. At the same time, the drive motor 14 synchronously controls the limiting of multiple springs, thereby improving the working efficiency in the spring testing process. Furthermore, the cylinder 31 can control the synchronous movement of multiple limiting members 40. The positions of the moving parts 30 are reasonably allocated inside the diagnostic box, thereby enabling the diagnostic device to diagnose multiple springs simultaneously while saving space. To a certain extent, this improves the efficiency of the diagnostic device in diagnosing springs.

[0035] After the moving part 30 and the corresponding limiting parts 40 on the mounting plate 131 limit the spring, the cylinder 31 is controlled to retract. During the retraction of the cylinder 31, the limiting parts 40 on the moving part 30 slide inside the first limiting block 17. The length of the spring extension is determined based on the retraction distance of the cylinder 31. Simultaneously, the spring force gauge 32 detects the spring's elasticity during the extension process. The retraction distance of the cylinder 31 and the data from the spring force gauge 32 are synchronously transmitted to the display screen 21, completing the spring diagnostic operation. During the extension and retraction of the cylinder 31, the limiting parts 40 on the moving part 30 slide within the first limiting block 17, using the first limiting block 17 to limit the limiting parts 40. This ensures that during the spring extension process, the path of the spring extension is kept on the same horizontal plane as the two corresponding limiting parts 40, allowing the limiting parts 40 to extend the spring. In the process, the spring balance 32 measures the spring, reducing the error generated during the measurement process. After the diagnosis is completed, the cylinder 31 is controlled again to drive the limiting piece 40 on the moving part 30 to slide towards the inside of the diagnostic box 10, controlling the spring from a taut state to a relaxed state. When the spring returns to its initial state, the drive motor 14 is controlled to rotate in the opposite direction, so that the limiting port on the mounting ring 42 on the mounting plate 131 is again facing the inner wall of the diagnostic box 10, making it easier to remove the spring from the mounting ring 42 on the mounting plate 131. The other end of the spring is removed from the limiting piece 40 on the moving part 30, completing the spring diagnosis operation. Then, the slide plate 12 is controlled to slide in the limiting groove 121 on the diagnostic box 10, taking the diagnosed spring out of the diagnostic box 10. The moving part 30 is pushed into the inside of the diagnostic box 10, completing the protection of the cylinder 31 and the spring balance 32.

After the multiple springs to be diagnosed are installed, attach the other side of the springs to be diagnosed onto the limiting parts (40) on the mounting plate (131). It should be noted that in the initial state, the limiting openings of the limiting parts (40) on the moving parts (30) and the corresponding limiting parts (40) on the mounting plate (131) are both facing one end of the inner wall of the diagnostic box (10). At this time, the springs attached to the mounting plate (131) are initially limited by the arc-shaped inner wall of the mounting ring (42). The second rotating rod (401) is controlled to rotate half a turn by the drive motor (14), so that the mounting ring (42) rotates half a turn under the action of the second rotating rod (401). Since multiple second rotating rods (401) rotate synchronously with the first rotating rod (141), multiple mounting rings (42) rotate half a turn under the action of the second rotating rod (401). Since in the initial state, the limiting holes of the limiting member (40) on the moving part (30) and the corresponding limiting member (40) on the mounting plate (131) are facing one end of the inner sidewall of the diagnostic box (10), after the mounting ring (42) on the mounting plate (131) rotates half a turn, the limiting holes of the mounting ring (42) on the moving part (30) and the mounting ring (42) on the mounting plate (131) face different directions.
