DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] For example, see Figures 1 to 10 As shown, the present invention discloses an insulation test device for a low-voltage intelligent power distribution cabinet, comprising a rotating mechanism 1, the rotating mechanism 1 comprising a box body 11, a hydraulic telescopic rod 12 is installed on the top surface of the box body 11, a sprinkler head 13 and a wire inlet groove 15 are arranged at the bottom of the box body 11, a plurality of sprinkler heads 13 are evenly distributed on the bottom surface of the box body 11, and the wire inlet groove 15 is located at one end of the bottom surface of the box body 11; A mechanism to be tested 3 is arranged below the box body 11. The mechanism to be tested 3 includes a cabinet 31 arranged below the box body 11. A power harness 32 is installed above one side of the cabinet 31, and a ground wire 33 is installed below the other side of the cabinet 31. The other end of the box body 11 is equipped with a detection mechanism 4, which includes a side plate 41 whose top side is installed on the output end of the hydraulic telescopic rod 12, a main rod 42 is installed on the upper end of the side of the side plate 41, a sub-rod 44 is installed on the top surface of the main rod 42, a conductive rod 46 is installed inside the sub-rod 44, a touch plate 47 is installed at the end of the conductive rod 46, and a connecting tube 491 is installed on the bottom side of the side plate 41; A wire clamping mechanism 5 is installed inside the box body 11 . The wire clamping mechanism 5 includes a conductive block 51 installed inside one end of the box body 11 .

[0020] The rotating mechanism 1 also includes a rotating groove 14 arranged at the center of the bottom surface of the box body 11, and a turntable 16 is rotatably connected in the rotating groove 14. A ratchet gear 17 and a gear ring 18 are installed on the top surface of the turntable 16. The gear ring 18 is rotatably connected to the turntable 16, and the ratchet gear 17 is located inside the gear ring 18. Two limit blocks 19 and two first torsion springs 191 are symmetrically arranged inside the gear ring 18. The limit blocks 19 are elastically connected to the inside of the gear ring 18 through the first torsion spring 191, and two reinforcement blocks 192 are symmetrically fixed to the bottom surface of the turntable 16.

[0021] A clamping mechanism 2 is installed at the bottom end of the reinforcement block 192, and the clamping mechanism 2 includes a shell 21 fixed to the bottom end of the reinforcement block 192, a motor 22 is installed on the top surface of the shell 21, a clamping gear 23 is arranged inside the shell 21, and the clamping gear 23 is installed at the output end of the motor 22. Two extension arms 24 are staggered and slidably connected in the shell 21, and the clamping gear 23 is meshed with the two extension arms 24 at the same time, and a clamping claw 25 is fixed to the outer end of each extension arm 24.

[0022] The detection mechanism 4 also includes a first rack 43 installed on the side of the side plate 41, a second rack 45 is installed on the side of the auxiliary rod 44, and a first spring 48 and a push block 49 are installed inside the end of the main rod 42. The push block 49 is elastically connected to the inside of the main rod 42 through the first spring 48.

[0023] In the initial state, the extension arm 24 slides out of the shell 21 to the maximum extent, so that the distance between the two clamps 25 is maximized, and then the cabinet 31 is transported to the clamp 25, and then the motor 22 is started. The motor 22 drives the extension arm 24 to slide inside the shell 21 through the clamping gear 23. The extension arm 24 drives the clamps 25 at their respective ends to approach each other, thereby holding the cabinet 31 tightly and making the cabinet 31 suspended in the air; the operator inserts the power harness 32 from the wire inlet slot 15 into the box body 11, so that the power harness 32 contacts the conductive block 51. Then start the hydraulic telescopic rod 12, the hydraulic telescopic rod 12 (the hydraulic telescopic rod 12 is a multi-stage telescopic rod) drives the detection mechanism 4 to move, the main rod 42 and the auxiliary rod 44 on the upper side of the side panel 41 are inserted into the box body 11, and finally the touch plate 47 at the end of the auxiliary rod 44 contacts the top surface of the conductive block 51. At the same time, the connecting tube 491 on the bottom side of the side panel 41 is connected to the ground wire 33 on the side of the cabinet 31, and the conductive block 51 is contacted by the touch plate 47, and the conductive rod 46 inside the auxiliary rod 44 connects the power harness 32 and the ground wire 33 to the detection device line to form a loop. The side panel 41 is built with relevant detection equipment for the insulation test and leakage detection of the distribution cabinet. After the line is connected, the insulation test equipment and leakage detection equipment inside the side panel 41 detect whether the insulation and leakage of the cabinet 31 are qualified.

[0024] After the insulation test and leakage test of the cabinet 31 are qualified, the external water source sprays water through the sprinkler head 13 at the bottom of the box body 11 to wet the cabinet 31. Then the leakage detection equipment inside the side panel 41 detects whether the cabinet 31 has leakage in a humid environment to further judge the quality of the cabinet 31.

[0025] By combining the leakage detection of the cabinet 31 in dry and wet environments, as well as the insulation test and other detection links together and conducting them in an orderly manner, the detection operation steps can be greatly reduced, the workload of operators can be reduced, and the detection efficiency can be improved. At the same time, reducing the operation steps can also reduce operational errors and errors, thereby improving the accuracy of the detection.

[0026] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 10 The wire clamping mechanism 5 also includes a wire clamping block 52 and a second spring 53 installed inside the box body 11 , and the wire clamping block 52 is elastically connected to the inside of the box body 11 through the second spring 53 .

[0027] A release mechanism 6 is provided inside the box body 11, and the release mechanism 6 includes a rotating shaft 61 and a lever 62 installed inside one end of the box body 11, a second torsion spring 63 is installed inside the lever 62, and the lever 62 is rotatably connected to the rotating shaft 61 through the second torsion spring 63, a blocking block 64 is fixed to one end of the lever 62, a sliding rod 65 and a third spring 66 are installed inside the box body 11 at the other end of the lever 62, the sliding rod 65 is elastically connected to the inside of the box body 11 through the third spring 66, and the other end of the lever 62 abuts against the end of the sliding rod 65, and a baffle 67 is installed in the box body 11 at the other end of the lever 62.

[0028] In order to improve the connection stability between the power harness 32 and the conductive block 51, a wire clamping block 52 and a second spring 53 are provided inside the box body 11. In a natural state, the elastic force of the second spring 53 acts on the wire clamping block 52, so that the wire clamping block 52 contacts the conductive block 51. When the power harness 32 is inserted into the box body 11 from the wire entry slot 15, the wire clamping block 52 pushes the power harness 32 close to the conductive block 51 under the elastic force of the second spring 53, and the wire clamping block 52 cooperates with the conductive block 51 to clamp the power harness 32, so that the electrical connection between the power harness 32 and the conductive block 51 is more stable, thereby improving safety. Moreover, the sides of the conductive block 51 and the wire clamping block 52 that contact the power harness 32 are both concave arc surfaces, which can increase the contact area with the power harness 32 and further improve the stability of the line connection.

[0029] During the process of inserting the main rod 42 into the box body 11, the push block 49 protruding from the side of the end of the main rod 42 will collide with the blocking block 64 at one end of the lever 62 during the movement. Since the inclined surface of the push block 49 contacts the blocking block 64 during this process, and there is a baffle 67 at the other end of the lever 62 to block the rotating shaft 61, the push block 49 is pushed into the main rod 42 by the blocking block 64 and compresses the first spring 48. After the push block 49 passes over the blocking block 64, the push block 49 pops out from the main rod 42 again under the elastic force of the first spring 48.

[0030] Since the cabinet 31 is wetted by water during the leakage detection process, it is necessary to remove the water stains on the surface of the cabinet 31 as much as possible after the detection is completed. Therefore, the cabinet 31 is driven to rotate by releasing the connection between the detection mechanism 4 and the power harness 32 and the ground wire 33 after the detection is completed, so as to preliminarily remove the water stains on the surface of the cabinet 31. The specific process is as follows: the hydraulic telescopic rod 12 is started, driving the side plate 41 away from the box body 11, and the side plate 41 drives the main rod 42 and the auxiliary rod 44 to slide out from the inside of the box body 11, and at the same time the connecting tube 491 is separated from the ground wire 33. During the sliding of the main rod 42 toward the outside of the box body 11, the touch plate 47 at the end of the auxiliary rod 44 separates from the conductive block 51, disconnecting the entire circuit; secondly, during the movement in this direction, the push block 49 protruding from the side of the end of the main rod 42 abuts against the blocking block 64, and exerts a force on the blocking block 64 to drive the lever 62 to swing, causing the lever 62 to swing around the rotating shaft 61. While the lever 62 stores force in the second torsion spring 63, its other end pushes the slide bar 65 to slide, and the slide bar 65 compresses the third spring 66 and squeezes the wire clamping block 52, causing the wire clamping block 52 to slide away from the conductive block 51 and compress the second spring 53. The wire clamping block 52 releases the wire harness 32, and the wire harness 32 disengages from the wire inlet slot 15 (the wire harness 32 is flexible). When the push block 49 passes over the blocking block 64, the lever 62 is reset under the elastic force of the second torsion spring 63, the slide bar 65 is reset under the elastic force of the third spring 66, and the clamping block 52 is again in contact with the conductive block 51 under the elastic force of the second spring 53. Then the main rod 42 drives the first rack 43 on its side to mesh with the gear ring 18, and the first rack 43 drives the gear ring 18 to rotate counterclockwise (as shown in the attached figure). Figure 3 As shown in the figure, the limit block 19 in the toothed ring 18 contacts the ratchet gear 17 through the first torsion spring 191. At this time, the rotation of the toothed ring 18 can drive the ratchet gear 17 to rotate through the limit block 19 (during the sliding process of the main rod 42 into the box body 11, the first rack 43 also drives the toothed ring 18 to rotate, but in this process, the toothed ring 18 rotates clockwise, and the limit block 19 will not contact the ratchet gear 17, so it will not drive the ratchet gear 17 to rotate, and the toothed ring 18 will rotate idly). The ratchet gear 17 drives the turntable 16 to rotate inside the rotating groove 14. The turntable 16 mobilizes the shell 21 to rotate through the reinforcement block 192, and the shell 21 drives the cabinet 31 to rotate using the clamp 25. Disconnecting the connection between the power harness 32 and the conductive block 51, and disconnecting the connection between the connecting cylinder 491 and the ground wire 33, is not only to disconnect the line and eliminate safety hazards, but also to avoid pulling the power harness 32 and the ground wire 33 during the rotation of the cabinet 31, so as to allow the tested mechanism 3 to rotate better.

[0031] Example 3: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 10A drying mechanism 7 is installed on both sides of the box body 11, and the drying mechanism 7 includes connecting arms 71 symmetrically fixed on both sides of the box body 11, and a cylinder 72 is installed at the end of the connecting arm 71. A shaft rod 73 is rotatably connected in the cylinder 72, and a plurality of blowing nozzles 74 are equidistantly installed on the shaft rod 73, and the plurality of blowing nozzles 74 protrude from the bottom surface of the cylinder 72, and each blowing nozzle 74 is connected to a hot air pipe 75.

[0032] The drying mechanism 7 also includes a long rod 76 slidably connected to the connecting arm 71 and the inside of the box body 11, a fourth spring 77 is installed inside the connecting arm 71, the long rod 76 is elastically connected to the connecting arm 71 through the fourth spring 77, a triangular plate 78 is installed in the cylinder 72, one end of the long rod 76 is installed on the side of the triangular plate 78, and a plurality of lifting rods 79 and a fifth spring 791 are equidistantly installed inside the cylinder 72, the lifting rod 79 is elastically connected to the inside of the cylinder 72 through the fifth spring 791, two bosses 792 are symmetrically fixed on both sides of the bottom end of each lifting rod 79, and an adjustment frame 793 is installed on the top surface of each blowing nozzle 74, and the two bosses 792 on each lifting rod 79 are slidably connected to the corresponding adjustment frame 793.

[0033] During the rotation of the cabinet 31, hot air enters each blowing nozzle 74 through the hot air pipe 75, and is then sprayed toward the surface of the cabinet 31 from the blowing nozzle 74 to evaporate the remaining water stains on the surface of the cabinet 31 and dry the water stains on the surface of the cabinet 31. The rotation of the cabinet 31 can reduce the dead corners covered by hot air, allowing as much hot air as possible to cover the surface of the cabinet 31, thereby accelerating the evaporation of water stains and improving the drying efficiency. When the main rod 42 slides out of the box body 11, it will also drive the second racks 45 on both sides of the auxiliary rod 44 to contact the long rod 76 at intervals. Each time it contacts the long rod 76, the long rod 76 slides into the connecting arm 71, compressing the fourth spring 77 and pushing the triangular plate 78 to slide into the cylinder 72. The triangular plate 78 squeezes the lifting rod 79, causing the lifting rod 79 to drop. The lifting rod 79 compresses the fifth spring 791 and presses down the blowing nozzle 74 through the connection between the protruding column 792 and the adjusting frame 793. The blowing nozzle 74 swings in the cylinder 72 with the shaft 73 as the rotating axis, so that the blowing direction of the blowing nozzle 74 changes, thereby increasing the coverage of the hot air and further improving the drying effect. When the lifting rod 79 presses down the blowing nozzle 74, the protruding column 792 slides in the adjusting frame 793.

[0034] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
