Therefore, during the production process of the distribution cabinet, an insulating layer needs to be coated on its inner and outer surfaces, and in order to ensure the stability of the insulation performance of the distribution cabinet, after production, an insulation performance detection operation needs to be carried out on the distribution cabinet.

[0003] In the prior art, when detecting the insulation performance of a distribution cabinet, a fixed-point current or voltage data monitoring method is usually used to detect the insulation performance of the distribution cabinet. The probes used for detecting insulation are difficult to fully cover the distribution cabinet. Even if monitoring probes are set at multiple points, it only expands the detection surface and is difficult to completely cover the surface of the distribution cabinet, resulting in incomplete and detailed detection results of the insulation performance of the distribution cabinet. And after the detection is completed, the staff can only judge whether there is a leakage situation in the distribution cabinet, and cannot accurately locate the position of the insulation layer hole. When repairing, it is usually only possible to re-spray the entire surface of the distribution cabinet with an insulating layer, which not only consumes a large amount of human and time costs, but also causes waste of insulating paint.

Specific implementation mode

[0022] In the embodiment, in conjunction with the accompanying drawings of the specification, the technical solution of this application will be clearly and completely described. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of this application.

[0023] Embodiment 1: The present invention provides a power distribution cabinet insulation performance detection device. Please refer to Figures 1 - 14, including a main unit 1, a connector and a contact member are connected to the main unit 1. A buzzer range of a digital multimeter is installed inside the main unit 1. The connector includes a cylinder shell 2, and a magnet 201 arranged in a surrounding manner is fixed at the bottom edge position of the cylinder shell 2. A first carrier 202 is installed inside the cylinder shell 2, and a second carrier 204 is installed inside the first carrier 202. A round rod 3 is fixed inside the second carrier 204, and the round rod 3 movably penetrates through the first carrier 202 and extends into the cylinder shell 2. A probe 301 is inserted at the bottom end of the round rod 3. The contact member includes a grip rod 9, and a contact ball 901 is fixed at one end of the grip rod 9. Uniformly distributed metal soft hairs 902 are fixed on the outer surface of the contact ball 901. The positive electrode of the digital multimeter is connected to the probe 301, and the negative electrode of the digital multimeter is connected to the metal soft hairs 902.

[0024] During the use of the device, the staff adheres the connector to the surface of the iron distribution cabinet through the magnetic adsorption of the magnet 201 to the iron distribution cabinet. In this state, the probe 301 installed at the bottom end of the round rod 3 penetrates through the insulating layer coated on the surface of the distribution cabinet and is directly attached to the distribution cabinet. Then, the staff holds the grip rod 9 and adheres the metal soft hairs 902 uniformly fixed on the outer surface of the contact ball 901 to the surface of the distribution cabinet. In this state, the positive electrode led out by the digital multimeter inside the main unit 1 delivers current to the probe 301, and the current is transmitted to the distribution cabinet through the probe 301. The staff holds the grip rod 9 and manipulates the metal soft hairs 902 fixed on the outer surface of the contact ball 901 to gradually sweep across the surface of the distribution cabinet. If there are holes in the insulating layer coated on the surface of the distribution cabinet, the existence of the holes will cause the metal soft hairs 902 to directly contact the iron layer inside the distribution cabinet, which makes the current flowing to the distribution cabinet return to the negative electrode of the digital multimeter inside the main unit 1 through the metal soft hairs 902, forming a current path, thereby triggering a buzzer alarm. If the insulating layer coated on the surface of the distribution cabinet is complete and comprehensive, the metal soft hairs 902 cannot directly contact the distribution cabinet through the insulating layer, and no path will be formed between the positive and negative electrodes of the digital multimeter inside the main unit 1, so no buzzer alarm will be issued. The above structural settings can effectively improve the convenience and efficiency of the staff in detecting the insulation performance of the distribution cabinet, and can quickly and accurately locate the parts with insulation holes, which to a certain extent improves the convenience of the staff in repairing the hole positions after detection.

[0025] Please refer to Figures 3 - 6 and Figure 13, the first carrier 202 is rotatably installed in the cylindrical shell 2. A grinding component and a painting component are installed in the second carrier 204. Both the grinding component and the painting component penetrate through the first carrier 202 and extend into the cylindrical shell 2. The round rod 3, the grinding component, and the painting component are evenly distributed around the rotation center of the first carrier 202. The grinding component includes a first prism rod 4 rotatably connected to the second carrier 204. The first prism rod 4 movably penetrates through the first carrier 202 and extends into the cylindrical shell 2. A first spline rod 401 is inserted at the bottom end of the first prism rod 4, and a grinding head 402 is fixed at the bottom end of the first spline rod 401. The painting component includes a second prism rod 5 rotatably connected to the second carrier 204. The second prism rod 5 movably penetrates through the first carrier 202 and extends into the cylindrical shell 2. A second spline rod 501 is inserted at the bottom end of the second prism rod 5, and a painting head 502 is fixed at the bottom end of the second spline rod 501. A driving component for driving the rotation of the first prism rod 4 and the second prism rod 5 is installed in the cylindrical shell 2. The driving component includes a first servo motor 6 fixedly installed in the cylindrical shell 2. Second gear rings 602 rotatably installed in the first carrier 202 are slidably sleeved on the outer sides of the first prism rod 4 and the second prism rod 5. The internal dimension of the second gear ring 602 is adapted to the outer dimensions of the first prism rod 4 and the second prism rod 5. A second gear ring 602 rotates coaxially in the first carrier 202. A second gear 603 meshing between the first gear 601 and the second gear ring 602 rotates in the first carrier 202.

[0026] During the use of the device, before using the probe 301 to make contact with the power distribution cabinet, to ensure the stability of the contact between the probe 301 and the iron layer in the power distribution cabinet, the insulating layer coated on the surface of the power distribution cabinet at the position where the contact will be made will be removed first by the grinding component. When performing the above operation, the first spline rod 401 is in close contact with the insulating layer on the surface of the power distribution cabinet. Then, the first servo motor 6 in the driving component is powered on and started, driving the second gear ring 602 to rotate. By means of the meshing of the second gear 603 with the second gear ring 602 and the first gear 601, rotational power is provided for the first gear 601. The rotational power of the first gear 601 is transmitted to the first prism rod 4, driving the grinding head 402 to rotate. Through the high-speed rotation of the grinding head 402, the insulating layer at the corresponding position is polished clean. Then, the device controls the rotation of the first carrier 202, so that the probe 301 is transferred to the position of the grinding head 402. The probe 301 penetrates through the polished insulating layer and makes direct contact with the iron layer on the power distribution cabinet.

[0027] After the device finishes detecting the insulation performance of the power distribution cabinet, the device will reapply the insulation layer on the position of the power distribution cabinet surface where the insulation layer was previously removed through the painting component. When performing the above operations, the device will control the rotation of the first carrier 202, so that the painting head 502 in the painting component is transferred to the position of the probe 301. Then, the painting head 502 is closely attached to the position of the power distribution cabinet surface where the insulation layer was removed. After the first servo motor 6 in the driving component is powered on and started, it will drive the second gear ring 602 to rotate. By means of the meshing of the second gear 603 with the second gear ring 602 and the first gear 601, the rotational power is transmitted to the first gear 601, and then the second prism rod 5 is driven to rotate. Insulating paint will be conveyed into the painting head 502. Through the rotation of the painting head 502, the insulating paint is evenly applied to the position where the insulation layer was previously removed. The outer dimension of the painting head 502 is larger than the outer dimension of the grinding head 402, which can ensure the stability during the reapplication of the insulation layer.

[0028] Please refer to Figures 3 - 6 and Figure 13 , the second carrier 204 is slidably inserted into the first carrier 202. A plurality of screw rods 7 are vertically fixed in the second carrier 204 and are distributed in a surrounding manner. And a screw sleeve 701 rotatably installed in the first carrier 202 is threadedly connected to the outer side of the screw rod 7. A fourth gear 702 is fixed to the outer side of the screw sleeve 701. A third gear ring 703 having the same size as the second gear ring 602 is commonly sleeved and meshed on the outer sides of the plurality of fourth gears 702. The probe 301 is slidably inserted into the bottom end of the round rod 3. A first spring 302 elastically supported between the round rod 3 and the probe 301 is movably sleeved on the outer side of the upper end of the probe 301. The first spline rod 401 is slidably inserted into the bottom end of the first prism rod 4. A second spring 403 elastically supported between the first prism rod 4 and the grinding head 402 is movably sleeved on the outer side of the first spline rod 401. The second spline rod 501 is slidably inserted into the bottom end of the second prism rod 5. A third spring 503 elastically supported between the second prism rod 5 and the painting head 502 is movably sleeved on the outer side of the second spline rod 501. In the non-loaded state, the bottom of the painting head 502 is below the bottom of the grinding head 402, and the bottom of the grinding head 402 is below the bottom of the probe 301.

[0029] During the use of the device, by sliding and inserting the second carrier 204 into the first carrier 202, and cooperating with the threaded connection between the screw rod 7 and the screw sleeve 701, the second carrier 204 can be driven to flexibly lift relative to the first carrier 202. When driving the screw sleeve 701 to rotate, the third gear ring 703 is driven to rotate by the first servo motor 6. By means of the engagement between the inner side of the third gear ring 703 and the fourth gear 702, the rotational power is transmitted to the screw sleeve 701. During the rotation of the screw sleeve 701, due to the threaded connection between the screw sleeve 701 and the screw rod 7, the screw sleeve 701 and the screw rod 7 are driven to move relative to each other, thereby realizing the lifting control between the second carrier 204 and the first carrier 202.

[0030] When the probe 301, the grinding head 402, and the painting head 502 are in the state of not being stressed at the bottom, the painting head 502 is at the bottom of the grinding head 402, and the grinding head 402 is at the bottom of the probe 301. With the elastic support of the first spring 302, the second spring 403, and the third spring 503 for the probe 301, the grinding head 402, and the painting head 502 respectively, this enables the device to flexibly control the contact state between the probe 301, the grinding head 402, and the painting head 502 and the surface of the distribution cabinet by controlling the lifting of the second carrier 204 according to actual needs. During use, when the bottom of the painting head 502 contacts the surface of the distribution cabinet, the grinding head 402 and the probe 301 do not contact the distribution cabinet. In this state, when the first servo motor 6 drives the second gear ring 602 to rotate, the first prism rod 4 and the second prism rod 5 will be driven simultaneously, but the grinding head 402 will not perform grinding operation on the surface of the distribution cabinet. When the bottom of the grinding head 402 contacts the surface of the distribution cabinet, the painting head 502 also contacts the surface of the distribution cabinet, and the probe 301 does not contact the surface of the distribution cabinet. In this state, when the first servo motor 6 drives the second gear ring 602 to rotate, the first prism rod 4 and the second prism rod 5 are driven to rotate simultaneously. During the high-speed rotation of the grinding head 402, it grinds the surface of the distribution cabinet, and when the painting head 502 rotates while adhering to the surface of the distribution cabinet, it will not damage the insulating layer on the surface of the distribution cabinet. When the probe 301 contacts the surface of the distribution cabinet, the grinding head 402 and the painting head 502 also contact the surface of the distribution cabinet. In this state, the grinding head 402 and the painting head 502 will not be driven to rotate, so they will not damage the insulating layer on the surface of the distribution cabinet.

[0031] During the use of the device, the outer dimension of the first spline rod 401 is adapted to the inner dimension of the first rib rod 4, and the outer dimension of the second spline rod 501 is adapted to the inner dimension of the second rib rod 5. This enables the sliding of the first spline rod 401 relative to the first rib rod 4 not to affect the rotation of the grinding head 402 driven by the first rib rod 4. Similarly, the sliding of the second spline rod 501 relative to the second rib rod 5 does not affect the rotation of the painting head 502 driven by the second rib rod 5. Through the sliding insertion of the probe 301 and the round rod 3, the sliding insertion of the first spline rod 401 and the first rib rod 4, the sliding insertion of the second spline rod 501 and the second rib rod 5, and the elastic support of the first spring 302, the second spring 403, and the third spring 503, combined with the lifting adjustment of the second carrier 204, the tightness when the probe 301, the grinding head 402, and the painting head 502 are in contact with the surface of the power distribution cabinet can be effectively improved, which is beneficial to ensuring the stability of the probe 301, the grinding assembly, and the painting assembly during the operation of the device.

[0032] Please refer to Figure 3 、 Figure 4 、 Figure 7 and Figure 13 As shown in, a first toothed ring 203 of the same size as the second toothed ring 602 is fixed on the first carrier 202. A spline shaft 604 is fixed on the drive shaft of the first servo motor 6, and a spline cylinder 605 is slidably sleeved on the outer side of the spline shaft 604. A third gear 606 meshing with the second toothed ring 602 is fixed on the spline cylinder 605. An electric push rod 607 parallel to the spline shaft 604 is fixed inside the cylinder shell 2, and a connecting plate 608 is fixed on the telescopic end of the electric push rod 607. The connecting plate 608 is rotatably connected to the spline cylinder 605.

[0033] During the use of the device, the electric push rod 607 is started. Through the movement of its telescopic end and with the connection of the connecting plate 608, the spline cylinder 605 and the third gear 606 fixed on its outer side can be driven to move, adjusting the meshing states of the third gear 606 with the first toothed ring 203, the second toothed ring 602, and the third toothed ring 703. After the first servo motor 6 is powered on and started, it will drive the spline shaft 604 fixedly connected to its drive shaft to rotate. The spline shaft 604 drives the spline cylinder 605 to rotate synchronously, and then drives the third gear 606 to rotate. The outer dimension of the spline shaft 604 is adapted to the inner dimension of the spline cylinder 605, and the sliding of the spline cylinder 605 along the spline shaft 604 will not interfere with the transmission of its rotational power. When it is necessary to control the rotation of the grinding head 402 and the painting head 502, the third gear 606 is adjusted to mesh with the second toothed ring 602, transmitting the rotational power to the second toothed ring 602. When it is necessary to control the rotation of the first carrier 202, the third gear 606 is adjusted to mesh with the first toothed ring 203, transmitting the rotational power to the first toothed ring 203. When it is necessary to control the lifting of the second carrier 204, the third gear 606 is adjusted to mesh with the third toothed ring 703, transmitting the rotational power to the third toothed ring 703. The above structural settings enable the power drive within the connector to be achieved only by relying on a single first servo motor 6, and the minimum number of first servo motors 6 can be set within the limited space inside the cylinder shell 2. This can not only effectively improve the structural rationality of the connector, but also help reduce the usage amount of the first servo motor 6, which is beneficial to reducing the manufacturing cost of the device.

A first adapter cylinder 404 that is rotationally connected to the outside of the first prism rod 4 is fixed inside the second carrier 204, and a first adapter pipe 405 is fixedly connected to the outside of the first adapter cylinder 404. A second adapter cylinder 504 that is rotationally connected to the outside of the second prism rod 5 is fixed inside the second carrier 204, and a second adapter pipe 505 is fixedly connected to the outside of the second adapter cylinder 504. A dust extraction device and an insulating paint supply pump are installed in the main machine 1. The first adapter pipe 405 penetrates to the center position of the top of the second carrier 204, and the second adapter pipe 505 penetrates into the first adapter pipe 405. A disc 8 is arranged above the second carrier 204, and a first adapter box 801 rotationally connected to the first adapter pipe 405 and a second adapter box 802 rotationally connected to the second adapter pipe 505 are fixed on the disc 8. A metal ring piece 803 coaxially arranged with the second carrier 204 is fixed on the disc 8, and the metal ring piece 803 is in sliding contact with the top end of the round rod 3.

[0035] During the use of the device, the dust extraction device in the main unit 1 is connected to the first adapter box 801 through a hose. When the grinding head 402 is used to grind and remove the insulation layer on the surface of the power distribution cabinet, the air pump in the main unit 1 is powered on and started, and the grinding head 402 is dusted by air suction. The dust and debris generated by the grinding head 402 enters the first adapter tube 404 through the first spline rod 401 and the channel opened in the first edge rod 4, and then enters the first adapter box 801 through the connection of the first adapter tube 405, and finally enters the dust extraction device. The grinding head 402 and the distribution cabinet are removed by active dust extraction. The dust and debris generated at the grinding position of the electric cabinet surface can effectively ensure the stability of the high-speed rotation of the grinding head 402 to remove the insulation layer on the surface of the distribution cabinet, and ensure the clean and stable operation of the equipment. The insulating paint supply pump in the main unit 1 is connected to the second adapter box 802 through a hose. When the insulating layer is applied to the surface of the distribution cabinet, the insulating paint is transported into the second adapter box 802 through the insulating paint supply pump, and then enters the second adapter tube 504 through the second adapter tube 505, and finally passes through the channel opened in the second edge rod 5 and the second spline rod 501, and is sprayed on the surface of the distribution cabinet from the brush head 502.

[0036] In the device, through the sliding connection between the metal ring piece 803 and the top of the round rod 3, when the first supporting platform 202 drives the probe 301 to rotate and adjust the position, it will not affect the power connection in the positive direction of the digital multimeter. Through the rotational connection between the first edge rod 4 and the first adapter tube 404, and the rotational connection between the first adapter tube 405 and the first adapter box 801, the air flow delivery can be prevented from being affected by the rotation of the first supporting platform 202 and the first edge rod 4. Similarly, through the rotational connection between the second edge rod 5 and the second adapter tube 504, and the rotational connection between the second adapter tube 505 and the second adapter box 802, the supply of insulating coating will not be affected by the rotation of the first supporting platform 202 and the second edge rod 5. Under the cooperation with each other, the operating stability of the device during actual use is effectively guaranteed.

[0037] See also Figure 8 and Figure 10 A turntable 903 is rotatably sleeved on one end of the grip 9 close to the contact ball 901, and a nozzle 904 is fixed at the edge of the turntable 903. A second servo motor 905 for driving the turntable 903 to rotate is fixed on the grip 9. During the use of the device, when the staff operates the device to detect the location of the insulation layer leakage, the staff can operate the device to drive the second servo motor 905 to power on and start, drive the turntable 903 to drive the nozzle 904 to rotate around the metal soft hair 902 evenly distributed on the outside of the contact ball 901, and during the rotation of the nozzle 904, the marking paint is sprayed to circle the leakage position. By marking the leakage position of the insulation layer during the detection process, it is convenient to uniformly repair it after the detection is completed, which improves the convenience of the staff to repair the insulation layer leakage after the detection to a certain extent.

[0038] The above is only the best implementation mode adopted by this application in combination with the current actual requirements, but the protection scope of this application is not limited thereto.
