Description

Technical Field

[0001] This invention relates to the field of insulation testing technology, specifically to a small high-voltage porcelain insulation testing device. Background Technology

[0002] High-voltage electrical porcelain is a type of functional ceramic used in power systems of 1 kV and above. It features low dielectric constant and dielectric loss, high insulation resistance and breakdown field strength, as well as excellent mechanical and thermal properties. Due to these properties, it is widely used in the manufacture of insulators, surge arresters, fuses, and other power transmission and transformation equipment, serving both electrical insulation and mechanical support functions.

[0003] In the high-voltage porcelain insulation testing process, a testing architecture is often used where multiple test pieces share a grounding busbar and leakage current is collected centrally. When a single test piece in the group experiences excessive leakage current or insulation breakdown, this method struggles to accurately locate the faulty individual piece, requiring repeated testing of each piece for troubleshooting. Furthermore, manually identified non-conforming pieces must be individually labeled, which, in batch testing conditions with densely packed test pieces, easily leads to mislabeling and omissions, directly impacting testing efficiency and sorting reliability. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a small high-voltage porcelain insulation testing device. It aims to solve the problems of difficulty in accurately locating the faulty single piece when leakage current exceeds the standard or insulation breaks down in a group of test pieces. This requires retesting each piece individually, and manual marking is required after a piece is judged to be unqualified, which is prone to mismarking or omission.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a small high-voltage porcelain insulation testing device, comprising a bottom support plate, two side support plates fixedly installed on the bottom support plate, a feeding mechanism, a waste collection rack and a finished product collection mechanism provided between the two side support plates, a feeding assembly provided above the waste collection rack and the finished product collection mechanism on the two side support plates, a gripping mechanism for gripping high-voltage porcelain on the two side support plates, and a conveying mechanism for conveying the gripping mechanism on the two side support plates;

[0006] Electric push rods are fixedly installed on both side support plates. A high-voltage detection contact is installed at the top of one electric push rod, and a grounding detection contact is installed at the top of the other electric push rod. The high-voltage detection contact and the grounding detection contact are used to contact the two ends of the high-voltage porcelain. The high-voltage detection contact is electrically connected to the high-voltage power supply, and the grounding detection contact is electrically connected to the leakage current sensor.

[0007] By adopting the above technical solution, the present invention triggers the clamping action by the pressure of the high-voltage porcelain itself, without the need to set up separate sensors or electronic control components. Compared with the cylinder or motor drive commonly used in the prior art, it simplifies the control logic, reduces manufacturing costs, and avoids electromagnetic interference from strong electromagnetic fields to the control system.

[0008] Preferably, the feeding mechanism includes two support frames fixedly installed on the bottom support plate, and a conveyor is erected between the two support frames. The conveyor belt on the conveyor is provided with a transverse positioning ridge and a vertical positioning ridge.

[0009] Preferably, the gripping mechanism includes a mounting box, on which two clamping blocks are mounted. The bottoms of the two clamping blocks are connected to a movable block. The movable block is slidably mounted in a strip-shaped slide rail opened on the surface of the mounting box. The bottom of the movable block is connected to a driving block. An adjustment component for adjusting the spacing is provided between the driving blocks.

[0010] Preferably, the conveying mechanism includes multiple synchronous pulleys rotatably mounted on the side support plate. When the multiple synchronous pulleys are on the same side, they are connected by the same synchronous belt. The synchronous pulleys are driven to rotate by a drive motor mounted on the side support plate. A fixing block is fixedly mounted on the top of the mounting box, and a guide rod is fixedly mounted on the side of the fixing block. The guide rod is slidably disposed in a moving channel opened on the side support plate, and a linkage slider for connecting the synchronous belt is installed at the end of the guide rod.

[0011] Preferably, the finished product collection mechanism includes a finished product collection rack fixedly installed on the bottom support plate, and a sliding buffer plate is provided inside the finished product collection rack. An elastic element is installed at the bottom of the buffer plate, and the end of the elastic element is installed on the inner wall of the finished product collection rack.

[0012] Preferably, the adjustment assembly includes an adjustment frame slidably installed in the mounting box, the adjustment frame having an eight-shaped guide groove, a sliding rod slidably installed in the guide groove, the sliding rod being fixed to both sides of the drive block, a T-shaped contact top plate installed on the top of the adjustment frame, the contact top plate vertically penetrating the mounting box and slidingly engaging with the mounting box, and an elastic element two installed at the bottom of the adjustment frame, the bottom end of the elastic element two being installed on the inner wall of the mounting box.

[0013] Preferably, strong magnetic blocks are installed at the bottom of the adjustment frame and on the inner wall of the mounting box. The bottom and sides of the strong magnetic blocks are seamlessly covered with high magnetic permeability material. A wedge block one is fixedly installed at the bottom of the adjustment frame. A support plate and a limiting guide rod are fixedly installed on the inner wall of the mounting box. A shielding plate for blocking the strong magnetic blocks on the inner wall of the mounting box is slidably installed on the support plate and the limiting guide rod. A wedge block two for cooperating with the wedge block one is fixedly installed on the side of the shielding plate. The wedge block two and the shielding plate are an integral structure.

[0014] Preferably, the unloading assembly includes an elliptical push plate rotatably mounted on a side support plate above the waste collection rack, an L-shaped contact plate fixedly mounted on the side of the shielding plate, an elastic element three installed between the contact plate and the support plate, the contact plate slidingly mounted in a strip-shaped opening on the side of the mounting box, the push plate located between the two contact plates, and the push plate being driven to rotate by a drive motor one mounted on the side support plate.

[0015] Preferably, the feeding assembly includes a positioning plate fixedly mounted on a side support plate above the finished product collecting mechanism. The positioning plate is located between two contact plates and has a triangular inclined surface for cooperating with the contact plates.

[0016] Preferably, the clamping block adopts a modular design and is provided with an arc-shaped groove, an elastic compression block is installed on the inner wall of the groove, and an elastic buffer sheet is installed on the contact top plate.

[0017] Working principle:

[0018] After the high-voltage porcelain to be tested is positioned by the horizontal and vertical positioning edges, it is transported to the gripping position by the conveyor. The drive motor drives the synchronous pulley and drives the synchronous belt. The synchronous belt drives the mounting box to move synchronously through the linkage slider, guide rod and fixing block.

[0019] After the mounting box moves to the gripping position, the high-voltage porcelain presses against the top plate and pushes the adjustment frame to move, causing the sliding rod to slide along the guide groove, which in turn causes the drive blocks to move closer to each other and moves the clamping block to complete the gripping operation of the high-voltage porcelain.

[0020] When the clamping blocks approach each other, the adjusting frame drives wedge block one to press against wedge block two, which in turn drives wedge block two to move the baffle away from the strong magnetic block on the inner wall of the mounting box. The two strong magnetic blocks attract each other, thereby closing the magnetic circuit of the strong magnetic block and locking the position of the adjusting frame.

[0021] After the high-voltage porcelain is moved to the detection position, the electric push rods on the two side support plates drive the high-voltage detection contact and the grounding detection contact to contact the two ends of the high-voltage porcelain, thereby forming a detection circuit to detect the insulation performance of the high-voltage porcelain.

[0022] If the high-voltage porcelain insulation fails the test, once it is moved to the top of the waste collection rack, the drive motor drives the push plate to rotate. The push plate, with its own elliptical contour, drives the two contact plates to move away from each other, thereby restoring the shielding plate's shielding of the strong magnetic block on the inner wall of the mounting box. At the same time, the adjusting frame quickly resets under the action of the elastic element, causing the clamping block to release the clamping limit on the high-voltage porcelain, and the high-voltage porcelain then falls into the waste collection rack.

[0023] If the insulation test of the high-voltage porcelain is qualified, after it is moved to the top of the finished product collection rack, the two contact plates and the positioning plate will move away from each other after they abut against each other, thereby restoring the shielding plate's shielding of the strong magnetic block on the inner wall of the installation box. At the same time, the adjusting frame will quickly reset under the action of the elastic element two, causing the clamping block to release the clamping limit on the high-voltage porcelain, and the high-voltage porcelain will then fall into the finished product collection rack.

[0024] This invention provides a small high-voltage porcelain insulation testing device, which has the following beneficial effects:

[0025] 1. This invention, by setting up a feeding mechanism, a gripping mechanism, a conveying mechanism, an electric push rod, detection contacts, a discharging assembly, a waste collection rack, and a finished product collection mechanism, utilizes the feeding mechanism to transport high-voltage electrical porcelain to the gripping position, the gripping mechanism to grip the high-voltage electrical porcelain, the conveying mechanism to move the high-voltage electrical porcelain to the detection position, and the electric push rod to drive the high-voltage detection contact and the grounding detection contact to perform insulation testing. For waste products that fail the test, the push plate in the discharging assembly controls the gripping mechanism to release the clamping limit on the waste product, which then falls into the waste collection rack. For finished products that pass the test, the positioning plate in the discharging assembly controls the gripping mechanism to release the clamping limit on the finished product, which then falls into the finished product collection rack. The entire process operates automatically and continuously, significantly improving the efficiency of the testing operation.

[0026] 2. This invention, by setting up an adjusting frame, sliding rod, driving block, clamping block, wedge block one, wedge block two, baffle plate, and strong magnetic block, utilizes the displacement of the adjusting frame to drive the sliding rod to slide along the guide groove, causing the driving blocks to move closer together and move the clamping block, thus completing the gripping operation of the high-voltage porcelain. When the clamping blocks move closer together, the adjusting frame drives wedge block one to press against wedge block two, causing wedge block two to move the baffle plate away from the strong magnetic block on the inner wall of the mounting box. The two strong magnetic blocks attract each other, realizing the magnetic circuit closure of the strong magnetic blocks and the self-locking position of the adjusting frame. This not only eliminates the interference of external magnetic fields on insulation detection, but also ensures reliable clamping of the high-voltage porcelain throughout the entire transportation process.

[0027] 3. This invention, by setting up a drive motor, a push plate, a contact plate, and a shielding plate, utilizes the movement of the contact plate to drive the movement of the shielding plate. If the insulation of the high-voltage porcelain fails the test, once it moves above the waste collection rack, the drive motor drives the push plate to rotate. The push plate, with its own elliptical contour, drives the two contact plates to move away from each other, thereby restoring the shielding plate's obstruction of the strong magnetic block on the inner wall of the mounting box. At the same time, the adjusting frame quickly resets under the action of the elastic element, causing the clamping block to release its clamping limit on the high-voltage porcelain, which then falls into the waste collection rack. The entire process requires no additional personnel operation, resulting in a high level of automation in waste collection.

[0028] 4. This invention uses a positioning plate, a contact plate, and a shielding plate. The positioning plate changes the movement path of the contact plate. If the high-voltage porcelain insulation test is qualified, after it moves to the top of the finished product collection rack, the two contact plates will move away from each other after they come into contact with the positioning plate, thereby restoring the shielding plate's obstruction of the strong magnetic block on the inner wall of the mounting box. At the same time, the adjusting frame quickly resets under the action of the elastic element two, causing the clamping block to release the clamping limit on the high-voltage porcelain. The high-voltage porcelain then falls into the finished product collection rack. No additional personnel are required to operate the entire process, and the automation level of finished product collection is high.

[0029] 5. By setting up modular clamping blocks, elastic squeezing blocks, and elastic buffer sheets, this invention can not only adapt to high-voltage porcelain of different diameters to achieve reliable clamping, but also use the elastic squeezing blocks and elastic buffer sheets to form insulation isolation for high-voltage porcelain, effectively avoiding the influence of conductive interference and ensuring accurate and reliable test results.

[0049] For details, please refer to the appendix. Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5The conveying mechanism 10 includes multiple synchronous pulleys 1002 rotatably mounted on the side support plate 2.

[0053] For details, please refer to the appendix. Figure 6 and attached Figure 7 The adjustment assembly includes an adjustment frame 906 that is slidably installed in the mounting box 901. The adjustment frame 906 has a figure-eight shaped guide groove. A sliding rod 905 is slidably installed in the guide groove. The sliding rod 905 is fixed to both sides of the drive block 904.

[0054] By setting up an adjustment frame 906, a sliding rod 905, a drive block 904, and a clamping block 902, the displacement of the adjustment frame 906 drives the sliding rod 905 to slide along the guide groove, causing the drive blocks 904 to move closer to each other and drive the clamping block 902 to move, thus completing the gripping operation of the high-voltage porcelain.

[0055] For details, please refer to the appendix. Figure 6 Appendix Figure 8 Appendix Figure 9 and attached Figure 10 Strong magnetic blocks 910 are installed on the bottom of the adjustment frame 906 and the inner wall of the mounting box 901. The bottom and sides of the strong magnetic blocks 910 are seamlessly covered with high magnetic permeability material. A wedge block 909 is fixedly installed on the bottom of the adjustment frame 906. A support plate 911 and a limiting guide rod 912 are fixed on the inner wall of the mounting box 901. A shielding plate 913 for shielding the strong magnetic blocks 910 on the inner wall of the mounting box 901 is slidably installed on the support plate 911 and the limiting guide rod 912. A wedge block 914 for cooperating with the wedge block 909 is fixedly installed on the side of the shielding plate 913. The wedge block 914 and the shielding plate 913 are an integral structure.

[0056] By setting up clamping blocks 902, adjusting frame 906, wedge block one 909, wedge block two 914, baffle plate 913 and strong magnetic block 910, when the clamping blocks 902 approach each other, the adjusting frame 906 drives wedge block one 909 to press against wedge block two 914, driving wedge block two 914 to move the baffle plate 913 away from the strong magnetic block 910 on the inner wall of the mounting box 901. The two strong magnetic blocks 910 attract each other, realizing the magnetic circuit closure of the strong magnetic block 910 and the position self-locking of the adjusting frame 906.

[0057] For details, please refer to the appendix. Figure 1 Appendix Figure 3 and attached Figure 10 The unloading assembly includes an elliptical push plate 7 rotatably mounted on the side support plate 2 above the waste collection rack 4, an L-shaped contact plate 915 fixedly mounted on the side of the shield plate 913, an elastic element 916 installed between the contact plate 915 and the support plate 911, the contact plate 915 slidingly mounted in the strip opening on the side of the mounting box 901, the push plate 7 located between the two contact plates 915, and the push plate 7 is driven to rotate by a drive motor 6 mounted on the side support plate 2;

[0058] By setting up a drive motor 6, a push plate 7, a contact plate 915, and a shielding plate 913, the movement of the contact plate 915 drives the movement of the shielding plate 913. If the insulation of the high-voltage porcelain fails the test, once it moves above the waste collection rack 4, the drive motor 6 drives the push plate 7 to rotate. The push plate 7, with its own elliptical contour, drives the two contact plates 915 to move away from each other, thereby restoring the shielding of the strong magnetic block 910 on the inner wall of the mounting box 901 by the shielding plate 913. At the same time, the adjusting frame 906 quickly resets under the action of the elastic element 908, driving the clamping block 902 to release the clamping limit on the high-voltage porcelain. The high-voltage porcelain then falls into the waste collection rack 4. The entire process requires no additional operation by personnel, and the level of automation in waste collection is high.

[0059] For details, please refer to the appendix. Figure 2 and attached Figure 3 The unloading assembly includes a positioning plate 8 fixedly installed on the side support plate 2 above the finished product collection mechanism 5. The positioning plate 8 is located between two contact plates 915. The positioning plate 8 is provided with a triangular inclined surface for cooperating with the contact plates 915.

[0060] By setting up a positioning plate 8, a contact plate 915, and a shielding plate 913, the positioning plate 8 changes the movement path of the contact plate 915. If the insulation test of the high-voltage porcelain is qualified, after it moves to the top of the finished product collection rack 501, the two contact plates 915 will move away from each other after they come into contact with the positioning plate 8, thereby restoring the shielding of the strong magnetic block 910 on the inner wall of the mounting box 901 by the shielding plate 913. At the same time, the adjusting frame 906 quickly resets under the action of the elastic element 908, driving the clamping block 902 to release the clamping limit on the high-voltage porcelain. The high-voltage porcelain then falls into the finished product collection rack 501. No additional personnel are required to operate the entire process, and the automation level of finished product collection is high.

[0061] For details, please refer to the appendix. Figure 6 and attached Figure 7 The clamping block 902 adopts a modular design and is equipped with an arc-shaped groove. An elastic squeezing block is installed on the inner wall of the groove, and an elastic buffer sheet is installed on the contact top plate 907.

[0062] By setting up modular clamping blocks 902, elastic compression blocks, and elastic buffer sheets, it can not only adapt to high-voltage porcelain of different diameters to achieve reliable clamping, but also use elastic compression blocks and elastic buffer sheets to form insulation isolation for high-voltage porcelain, effectively avoiding the influence of conductive interference and ensuring accurate and reliable test results.

[0063] Working principle:

[0064] After the high-voltage porcelain to be tested is positioned by the horizontal positioning ridge 303 and the vertical positioning ridge 303, it is transported to the gripping position by the conveyor 302. The drive motor 1001 drives the synchronous pulley 1002 and drives the synchronous belt 1003 to drive the synchronous belt. The synchronous belt 1003 drives the mounting box 901 to move synchronously through the linkage slider 1004, the guide rod 1005 and the fixing block 1006.

[0065] After the mounting box 901 moves to the gripping position, the high-voltage porcelain abuts against the top plate 907 and pushes the adjusting frame 906 to move, causing the sliding rod 905 to slide along the guide groove, causing the driving blocks 904 to move closer to each other and drive the clamping block 902 to move, thus completing the gripping operation of the high-voltage porcelain.

[0066] When the clamping blocks 902 approach each other, the adjusting frame 906 drives the first wedge block 909 to press against the second wedge block 914, which in turn drives the second wedge block 914 to move the baffle plate 913 away from the strong magnetic block 910 on the inner wall of the mounting box 901. The two strong magnetic blocks 910 attract each other, thereby closing the magnetic circuit of the strong magnetic block 910 and locking the position of the adjusting frame 906.

[0067] After the high-voltage porcelain is moved to the detection position, the electric push rods 11 on the two side support plates 2 drive the high-voltage detection contact 12 and the grounding detection contact 12 to contact the two ends of the high-voltage porcelain, thereby forming a detection circuit to detect the insulation performance of the high-voltage porcelain.

[0068] If the high-voltage porcelain fails the insulation test, once it is moved above the waste collection rack 4, the drive motor 6 drives the push plate 7 to rotate. The push plate 7 uses its own elliptical contour to drive the two contact plates 915 away from each other, thereby restoring the shielding plate 913 from blocking the strong magnetic block 910 on the inner wall of the mounting box 901. At the same time, the adjusting frame 906 quickly resets under the action of the elastic element 908, driving the clamping block 902 to release the clamping limit on the high-voltage porcelain, and the high-voltage porcelain then falls into the waste collection rack 4.

[0069] If the high-voltage porcelain insulation test is qualified, after it is moved above the finished product collection rack 501, the two contact plates 915 will move away from each other after they abut against the positioning plate 8, thereby restoring the shielding plate 913 from blocking the strong magnetic block 910 on the inner wall of the mounting box 901. At the same time, the adjusting frame 906 will quickly reset under the action of the elastic element 908, driving the clamping block 902 to release the clamping limit on the high-voltage porcelain, and the high-voltage porcelain will then fall into the finished product collection rack 501.

[0070] Although embodiments of the present invention have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
