[0050] A bearing part 5 for placing the ring main unit to be detected is arranged outside the test body 1 in a matched mode, a butt joint assembly 6 is arranged between the bearing part 5 and the test body 1, and the bearing part 5 and the test body 1 are detachably installed through the butt joint assembly 6, wherein the detachable installation design between the bearing part 5 and the test body 1 can facilitate quick replacement of the bearing part 5.

[0051] It should be noted that the cable inlet sealing performance of the ring main unit can be tested and the air leakage point position can be accurately positioned by cooperation of the cable inlet detection assembly and the sealing assembly 411, and the test part 4 can be stored and packaged in the non-use state.

[0052] Specifically, as shown in the drawings, Figures 4-5 The test part 4 comprises a bracket 41, a vertical plate 42 is fixedly arranged at the middle part of the bottom of the bracket 41, and one gas cylinder 1 is fixedly arranged at the left and right sides of the vertical plate 42, one end of the other gas cylinder 1 is fixedly connected with the inner wall of the receiving bin 2, a sliding groove can be formed in the inner side of the receiving bin 2, and limiting blocks are slidably connected in the corresponding sliding grooves and arranged at the left and right sides of the bracket 41, so as to limit the extension amount of the bracket 41, the cable inlet detection assembly is arranged at the other end of the other gas cylinder 1, a blocking strip 43 and a supporting plate 44 are fixedly arranged at the top of the bracket 41, and a swing assembly is arranged between the blocking strip 43 and the supporting plate 44, wherein the blocking strip 43 is used for limiting the swing angle of the swing assembly, and the supporting plate 44 is used for supporting the swing assembly;

[0053] The swing assembly comprises two ear seats 45 fixedly arranged at the top of the bracket 41 and close to the blocking strip 43, a gear one 46 driven to rotate by a servo motor is rotatably arranged between the two ear seats 45, a swing plate 47 is arranged at the outer side of the ear seat 45, a gear two 48 engaged with the gear one 46 is fixedly arranged at the bottom end of the swing plate 47, the sealing assembly 411 is arranged at one side of the swing plate 47, and a gas cylinder 2 for driving the sealing assembly 411 to extend and retract is fixedly arranged at the side, away from the sealing assembly 411, of the swing plate 47.

[0054] The yaw assembly also includes an arc rod 49 fixed between the stop bar 43 and the bracket 41 and a through hole 410 on the yaw plate 47 corresponding to the arc rod 49. The arc rod 49 is movably inserted into the corresponding through hole 410 to limit the yaw trajectory of the yaw plate 47 and ensure that the gear 1 46 and the gear 2 48 are always in a meshed state.

[0055] It should be noted that during the test of the sealing performance of the incoming cable of the ring main unit, the ring main unit to be tested is placed on the support part 5, and the cylinder one connected to the storage compartment 2 is activated. The extension of the cylinder one is used to push the bracket 41 carrying the swing component out of the storage compartment 2. When the bracket 41 is pushed out until the swing component is completely exposed in the storage compartment 2, the pushing out of the bracket 41 is stopped. At the same time, the servo motor is activated to drive the gear one 46 to rotate. The meshing between the gear one 46 and the gear two 48 is used to drive the swing plate 47 to swing upward along the arc rod 49 along with the gear two 48 until the side of the swing plate 47 where the sealing component 411 is installed is in contact with the stop strip 43. At this time, the swing plate 47 changes from the initial state of overlapping the upper end of the support plate 44 to... Figure 4 In the vertical position shown, the sealing assembly 411 is then pushed by starting cylinder two to seal the inlet of the ring main unit.

[0056] Specifically, such as Figures 4-6 As shown, the sealing assembly 411 includes a recess 4111 formed on the surface of the swing plate 47. Inside the recess 4111, there is a base plate 4112 fixedly connected to the telescopic end of the cylinder 2. A panel 4114 is provided on one side of the base plate 4112. An annular airbag 4113 is fixedly provided between the base plate 4112 and the panel 4114. The dimensions of the base plate 4112 (referring to length and width, the same below) are larger than the dimensions of the inner opening of the inlet chamber of the ring main unit to be tested, while the dimensions of the panel 4114 are slightly smaller than the dimensions of the inner opening of the inlet chamber of the ring main unit to be tested. In this way, the inflated annular airbag 4113 and the base plate 4112 pressed against the inlet chamber of the ring main unit to be tested can be used to double seal the inlet chamber opening of the ring main unit to be tested, so as to prevent the gas filled into the inlet chamber from leaking from here.

[0057] The sealing assembly 411 also includes an air pump 4115 fixed on the surface of the swing plate 47. The air pump 4115 has a main air pipe 4116 that passes through the bottom plate 4112 and the front panel 4114 in sequence. A secondary air pipe 4117 is provided between the main air pipe 4116 and the annular airbag 4113. Solenoid valves are installed on both the main air pipe 4116 and the secondary air pipe 4117 to control the inflation status of the annular airbag 4113 and the incoming line chamber of the ring network cabinet to be tested.

[0058] It should be noted that, in the process of plugging the inlet chamber of the ring main unit to be detected, the gas pump 4115 is started to fill gas into the inlet chamber after the sealing assembly 411 is pushed by the cylinder two to plug the inlet chamber of the ring main unit, during which the electromagnetic valves on the main gas pipe 4116 and the auxiliary gas pipe 4117 are in the open state. When the annular air bag 4113 is filled with gas to plug the inlet chamber, the electromagnetic valve on the auxiliary gas pipe 4117 is closed to keep the annular air bag 4113 in a constant inflated state, and the gas continues to be filled into the plugged inlet chamber. Then, the inlet detection assembly is used to detect the sealing of the cable inlet area from the outside of the ring main unit.

[0059] Specifically, as shown in Figures 7-9 and Figure 15 , the inlet detection assembly includes a mounting seat 412 fixed at the extension end of the corresponding cylinder one, a lifting groove and a driving groove are formed on the outer side of the mounting seat 412, and a through groove 414 is formed between the lifting groove and the driving groove. A lifting frame 413 is slidably installed in the lifting groove, a straight rack 415 is fixedly arranged on the side of the lifting frame 413 facing the driving groove, a gear three 416 driven by a servo motor is arranged in the driving groove, the gear three 416 is engaged with the straight rack 415, and a linkage one 417 is arranged in the lifting frame 413. Among them, the lifting groove is arranged in a cross-shaped structure, and a guide bar is arranged on the side of the lifting frame 413 away from the straight rack 415, so as to form a cross-shaped lifting seat matched with the cross-shaped lifting groove by using the guide bar, the straight rack 415 and the lifting frame 413. The meshing area of the gear three 416 and the straight rack 415 is engaged with the straight rack 415 through the through groove 414, so as to ensure stable lifting of the lifting frame 413.

[0060] Specifically, the linkage one 417 includes three rotating shafts rotatably installed in the lifting frame 413 and a sealing plate one fixed on the outer side of the lifting frame 413. A horizontal worm is rotatably installed between the sealing plate one and the inner wall of the lifting frame 413. A bevel gear one is fixedly sleeved on the outer side of the horizontal worm. A bevel gear two engaged with the bevel gear one is fixedly sleeved on the outer side of the centrally arranged rotating shaft. The centrally arranged rotating shaft is driven to rotate by a driving motor installed on the inner side of the lifting frame 413. The rotating shafts at both ends are fixedly sleeved with a worm gear one engaged with the horizontal worm.

[0061] The incoming line detection assembly further comprises two straight bars 418 fixedly sleeved outside the rotating shafts at the two ends, and each end of the two straight bars 418 is fixedly provided with an arc block 419, so that the relative rotation of the cross worm can be controlled to control the relative rotation of the worm gears outside the rotating shafts at the two ends, thereby controlling the closing and opening movements of the arc blocks 419 at the ends of the two straight bars 418, and the inside of each arc block 419 is provided with an arc in a T-shaped structure, and the inside of each arc in a T-shaped structure is slidably connected with an arc strip 420.

[0062] The outside of each arc block 419 is provided with a slot 421 in communication with the corresponding arc in a T-shaped structure, and the inside of each slot 421 is rotatably provided with a gear four 423 engaged with the corresponding tooth groove 422 through a rotating rod, one of the gear fours 423 is driven to rotate by a servo motor installed outside the corresponding arc block 419, and the other gear four 423 is provided with a detent 424 between the inner wall of the corresponding slot 421 and the gear four 423, wherein the detent 424 comprises a straight rod fixed to the inner wall of the corresponding slot 421 and a positioning cylinder movably sleeved outside the bottom end of the straight rod, and further comprises an inner concave spherical groove provided on the surface of the corresponding gear four 423, a straight spring fixedly connecting the positioning cylinder and the inner wall of the corresponding slot 421 is sleeved outside the straight rod, the bottom end of the positioning cylinder is also provided as a spherical surface matched with the inner concave spherical groove, and the spherical surface of the positioning cylinder is larger than the spherical surface of the inner concave spherical groove (i.e. only part of the positioning cylinder is embedded in the inner concave spherical groove), so that the detent 424 does not affect the rotation of the corresponding gear four 423.

[0063] The inside of one of the arc strips 420 is fixedly provided with an L-shaped seat 425, the top end of the L-shaped seat 425 is rotatably provided with a swing seat 426 driven to rotate by a servo motor, and the swing seat 426 is provided with a nozzle 427 at one end, wherein the liquid inlet end of the nozzle 427 is connected with an external soap tank through a liquid supply pipe, and the soap in the soap tank is supplied by a pump.

[0064] Further, an infrared range finder is arranged outside the rotating shaft corresponding to the centrally arranged rotating shaft of the lifting frame 413, which is used to detect the distance between the lifting frame 413 and the cable at the bottom end of the ring main unit to be detected, so as to ensure that the circle surrounded by the two arc strips 420 after closing is concentrically arranged with the cable, in addition, an image sensor is arranged at the end of the swing seat 426, which is used to detect the position of the area of the cable inlet of the ring main unit, so that the soap can be accurately applied to the area.

[0065] It should be noted that in the process of detecting the sealing performance of the cable inlet of the ring main unit, after the inlet of the cable chamber of the ring main unit is closed by the sealing assembly 411 driven by the second air cylinder, the mounting seat 412 is pushed towards the cable by the corresponding first air cylinder, and the advancing amount of the mounting seat 412 is controlled according to the feedback signal of the infrared range finder. After the mounting seat 412 is stopped, the corresponding servo motor is controlled to drive the centrally arranged shaft to rotate, the bevel gear one is driven to rotate by the rotating horizontal worm, so as to drive the arc blocks 419 at the ends of the two straight bars 418 to close, and when the two arc blocks 419 are completely closed, the corresponding gear four 423 is driven to rotate by the corresponding servo motor, and then the corresponding arc bar 420 is driven to move along the arc of the T-shaped structure, and the other arc bar 420 is synchronously moved under the pushing of the arc bar 420.

[0066] During the passive movement of the other arc bar 420, as the arc bar 420 moves passively, the spherical end of the positioning cylinder is pushed out of the concave spherical groove on it, and after the passive movement of the arc bar 420 is completed, the spherical end of the positioning cylinder is inserted into the concave spherical groove again. During the movement of the arc bar 420 along the arc of the T-shaped structure, the L-shaped seat 425 installed on the inner side of the arc bar 420 moves synchronously, and during this process, the swing seat 426 swings under the driving of the corresponding servo motor, so that the nozzle 427 is directed to the area to be detected. It should be further noted that during the process of spraying the soap solution to the specified area by the nozzle 427, the gear three 416 is driven to rotate by the corresponding servo motor to drive the lifting frame 413 to move along the lifting groove of the cross-shaped structure, so as to adjust the distance between the nozzle 427 and the area sprayed with the soap solution. After the spraying of the soap solution is completed, the arc bar 420 is moved to determine whether the sealing is good and the location of the sealing leak point according to the feedback signal of the image sensor.

[0067] The above detection of the sealing performance of the cable inlet of the ring main unit is to detect whether the soap film at the cable inlet of the ring main unit produces bubbles by the image sensor, and the location of the sealing leak point can also be determined according to the location of the bubbles.
