Description

Technical Field

[0001] The present invention belongs to the technical field of insulation detection, and particularly relates to an insulation detection device for a ring main unit cabinet body. Background Art

[0002] The working principle of this insulation detection device is mainly based on the measurement of insulation resistance or insulation loss current. By applying a specific voltage (DC or AC) to the device or circuit under test, and then measuring the current to calculate the insulation resistance or insulation loss current;

[0003] However, when the ring main unit cabinet body is transported to the detection position, the cabinet door or panel of the ring main unit is conveyed to the designated position by means of transmission to facilitate batch and rapid detection. Then, during the conveying process or the detection process, the detector will also contact the cabinet door or panel, which results in poor stability of the cabinet door or panel during insulation detection, and the center of gravity position will change. This is because the center of the detection part has its parameters adjusted in advance, which will lead to errors in the computer information transmission at the place where errors finally occur, affecting subsequent rework and maintenance work;

[0020] As a preferred technical solution of an insulation detection device for a ring main unit cabinet body, the moving structure includes motion mechanisms for the X, Y, and Z axes.

[0021] Advantages of the present invention:

[0022] 1. When the insulation detection device of the ring main unit cabinet body gradually approaches the side plate by relying on the limit table, the hollow rubber cylinder will gradually fit onto the side plate of the ring main unit cabinet. The hollow rubber cylinder will move deeper into the first guiding channel. The cooperation of the elastic member and the hollow rubber cylinder can further limit the side plate. At this moment, the rubber T rod can act on the inner hollow cylinder due to the movement of the hollow rubber cylinder. Under the action of the middle-section corrugated pipe and relying on the drawing characteristics, the hollow rubber cylinder can be vacuumized. At this moment, when the hollow rubber cylinder acts on the side plate of the ring main unit cabinet, it can rely on the dual actions of the limit pad and the hollow rubber cylinder to ensure the stability of the side plate of the ring main unit cabinet during insulation detection;

[0023] 2. When the insulation detection device of the ring main unit cabinet body is transported to the detection table position by being picked up by the side plate, the outer tooth column will rub against the linkage bar. Under the meshing action, the outer tooth column rotates, and the second convex column moves synchronously. Under the action of the inclined surfaces of the second convex column and the first convex column, the high surface position of the second convex column can lift the first convex column. When it moves 180 degrees, at this time, the high surface of the second convex column corresponds to the high surface of the first convex column. At this time, the top of the first convex column is inside the inner hollow cylinder, and the position of the rubber T-bar will be limited. When the detector touches and detects the side plate, the elastic member will not play a role due to vibration, thereby improving the stability effect and detection accuracy during the insulation detection of the ring main unit cabinet body;

[0024] 3. When the insulation detection device of the ring main unit cabinet body relies on the limit platform moving to the position of the side plate of the ring main unit, it drives a pair of limit platforms to move towards the edge of the side plate of the ring main unit. The limit pad will first fit with the edge of the side plate of the ring main unit. When there is a deviation in the coordinates of the side plate of the ring main unit, the motor drives the lead screw to change the position of the transverse moving seat, and the limit pad adjusts its position at this time to adjust the balance point position of the side plate of the ring main unit to ensure the accuracy during the insulation detection of the ring main unit cabinet body.

[0035] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings of the specification.

[0036] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate or selectively exclusive of other embodiments.

[0038] Furthermore, the present invention is described in detail with reference to the schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross-sectional views showing the device structures will be enlarged locally not in accordance with the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0039] Embodiment, refer to Figure 1, An insulation detection device for a ring main unit cabinet body, including a guiding rail 10, a detection table 11, a moving structure 12 and a detector 13; the detection table 11 is placed below the guiding rail 10, the moving structure 12 is movably arranged on the detection table 11, the moving structure 12 includes motion mechanisms for the X, Y and Z axes, the detector 13 is arranged on the moving structure 12, and a bearing frame 14 is installed at the corner position of the guiding rail 10;

[0040] Through the above content, the following can be achieved: when the limiting table 36 is in the initial position, it picks up the side plate of the ring main unit, and the guiding rail 10 transports the side plate of the ring main unit to the position of the detection table 11. On the detection table 11, the moving structure 12 enables the detector 13 to move in different directions, so as to facilitate the detector 13 to detect each local position of the side plate of the ring main unit;

[0041] Refer to Figure 2 and 3 , There is an outer cover 31 that moves telescopically on the guiding rail 10. A bearing table 32 and a movable column 33 are fixedly connected in the middle of the outer cover 31. A linkage arm one 34 is hinged at the corner position of the bearing table 32. A linkage arm two 35 is hinged outside the movable column 33. A limiting table 36 is hinged at the part where the linkage arm one 34 and the linkage arm two 35 both face the cabinet side plate; a hydraulic part one 37 is installed above the outer cover 31. A linkage table 38 is installed at the movable part of the hydraulic part one 37. The linkage table 38 is directionally arranged along the inner edge of the outer cover 31. A linkage arm three 39 is hinged at the edge position of the linkage table 38. The linkage arm three 39 and the linkage arm two 35 are in a hinged relationship.

[0042] Through the above content, the following can be achieved: relying on the hydraulic part one 37, the position of the linkage table 38 can be changed. Relying on the cooperation of the linkage arm three 39, the linkage arm two 35 can be linked at this moment, and with the assistance of the linkage arm one 34, the position of the limiting table 36 can be linked and changed at this time;

[0043] Refer to Figure 4 and 6, an adjustment module 51 and a stabilization module 40 are arranged in the limit platform 36. The adjustment module 51 includes a second guiding channel 52, a receiving seat 53, a transverse movement seat 54, a limit pad 55 and a second hydraulic component 56. The second guiding channel 52 is reserved at the inner edge of the limit platform 36. The receiving seat 53 telescopically moves in the second guiding channel 52. The transverse movement seat 54 telescopically moves in the receiving seat 53. The limit pad 55 abuts against the part of the transverse movement seat 54 facing the cabinet side plate, and the limit pad 55 has a flexible feature. The second hydraulic component 56 is arranged at the middle position of the limit platform 36. The movable part of the second hydraulic component 56 abuts against the receiving seat 53. A lead screw 57 is hinged in the receiving seat 53. A circular channel is milled on the transverse movement seat 54, and threads are milled on the inner edge of the circular channel. The lead screw 57 is threadedly connected to the transverse movement seat 54 through the threads. A motor 58 is abutted at the edge part of the receiving seat 53. The movable part of the motor 58 abuts against the lead screw 57. A sensor can be arranged on the back of the carrier platform 32 to provide a basis for the operation of the motor 58;

[0044] Through the above, it can be realized that when the limit platform 36 moves to the position of the side plate of the ring main unit cabinet, a pair of limit platforms 36 are driven to move towards the edge part of the side plate of the ring main unit cabinet. The limit pad 55 will first fit against the edge part of the side plate of the ring main unit cabinet. With the flexible feature of the limit pad 55 itself, it can avoid causing dents on the edge part of the side plate of the ring main unit cabinet. Depending on the sensor, the coordinates of the side plate of the ring main unit cabinet can be obtained at this time. At this time, the motor 58 can drive the lead screw 57 to change the position of the transverse movement seat 54. The limit pad 55 adjusts its position at this moment to adjust the balance point position of the side plate of the ring main unit cabinet to ensure the accuracy during the insulation detection of the ring main unit cabinet body, and drive the second hydraulic component 56 to work. And during this process, the limit platform 36 continues to move;

[0045] Refer to Figure 4 , the stabilization module 40 includes a first guiding channel 41, a hollow rubber cylinder 42, an elastic component 43 and an inner hollow cylinder 45. The first guiding channel 41 is milled on the inner edge of the limit platform 36. The first guiding channel 41 is distributed on the upper and lower sides of the second guiding channel 52. The hollow rubber cylinder 42 telescopically moves in the first guiding channel 41. One side of the hollow rubber cylinder 42 facing the side plate is made of a flexible material. The elastic component 43 is arranged at the part of the hollow rubber cylinder 42 in the first guiding channel 41. The other part of the elastic component 43 abuts against the inner edge of the first guiding channel 41. The inner hollow cylinder 45 is abutted at the opposite parts of a pair of limit platforms 36. A rubber T-bar 44 telescopically moves in the inner hollow cylinder 45. The other part of the rubber T-bar 44 abuts into the first guiding channel 41 to abut against the hollow rubber cylinder 42. A middle-section corrugated pipe 46 is connected between the part of the inner hollow cylinder 45 facing the limit platform 36 and the hollow rubber cylinder 42;

[0046] Through the above, the following can be achieved: as the limiting platform 36 gradually approaches the side plate of the ring main unit, the hollow rubber cylinder 42 will gradually fit onto the side plate of the ring main unit. The hollow rubber cylinder 42 will move towards the deep part of the guiding channel one 41. At this time, the elastic member 43 will deform under the load and can limit the side plate of the ring main unit by relying on the hollow rubber cylinder 42. The rubber T-bar 44 can act on the inner hollow cylinder 45 due to the movement of the hollow rubber cylinder 42. Under the action of the middle-section corrugated pipe 46 and relying on the pulling and drawing characteristics, the hollow rubber cylinder 42 can be vacuumized. When the hollow rubber cylinder 42 acts on the side plate of the ring main unit at this time, the stability of the side plate of the ring main unit during insulation detection can be ensured by the dual action of the limiting pad 55 and the hollow rubber cylinder 42.

[0047] Referring to Figure 1 , 4 and 5, a square frame 20 is installed along the inner edge of the carrier 14 near the detection table 11. A directional column 21 is arranged in the square frame 20. A docking channel 23 is milled on the inner hollow cylinder 45. An outer cylinder 22 is arranged at the outer position of the inner hollow cylinder 45 near the docking channel 23. A first convex column 24 telescopically moves in a directional manner in the outer cylinder 22. Among them, when the first convex column 24 is not affected by the second convex column 26, it can reset by relying on its own gravity. The lower inner edge of the outer cylinder 22 is hinged with a second convex column 26. The opposite surfaces of the first convex column 24 and the second convex column 26 are each composed of a high part, a low part, and an inclined surface. A linkage bar 25 is arranged on the surface of the directional column 21 facing the outer cylinder 22. Tooth patterns are intermittently arranged on the linkage bar 25. The lower part of the outer cylinder 22 is hinged with an external tooth column 27. The external tooth column 27 is docked with the second convex column 26. The external tooth column 27 is meshed and connected with the toothed part of the linkage bar 25;

[0048] The following can be achieved: after the side plate is picked up by tweezers, the position of the rubber T-bar 44 is at the deepest part of the inner hollow cylinder 45. At the same time, the lower surface of the second convex column 26 corresponds to the upper surface of the first convex column 24, the upper surface of the second convex column 26 corresponds to the lower surface of the first convex column 24, and the inclined surface of the second convex column 26 corresponds to the inclined surface of the first convex column 24. When the side plate of the ring main unit is transported to the detection table 11 for detection after being picked up by tweezers, the part of the external tooth column 27 will rub against the linkage bar 25. Under the action of meshing, the external tooth column 27 rotates. At this time, the second convex column 26 spirals. Under the action of the inclined surfaces of the second convex column 26 and the first convex column 24, the upper surface position of the second convex column 26 can lift the first convex column 24. When it moves 180 degrees, at this time, the upper surface of the second convex column 26 corresponds to the upper surface of the first convex column 24. At this time, the top of the first convex column 24 is inside the inner hollow cylinder 45. At this time, the position of the rubber T-bar 44 will be limited. When the detector 13 touches and detects the side plate, at this time, the elastic member 43 will not play a role due to jitter, thereby improving the stability effect and detection accuracy during the insulation detection of the ring main unit cabinet body; the single-segment tooth pattern on the linkage bar 25 can make the second convex column 26 rotate one circle to facilitate the synchronous rotation of multiple second convex columns 26. When reaching the accurate position of the detection table 11, the external tooth column 27 is at the middle position of the single-segment tooth pattern to ensure that the first convex column 24 can be lifted.

[0049] It should be understood that in the development process of any actual implementation, in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those ordinary technical personnel who benefit from this disclosure, without excessive experimentation, the development efforts will be a routine task of design, manufacturing, and production.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
