[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0034] For example 1, please refer to Figures 1 to 10 As shown, the present invention discloses an insulation test device for a low-voltage intelligent distribution cabinet, comprising a rotating mechanism 1, the rotating mechanism 1 comprising a box body 11, a hydraulic telescopic rod 12 being installed on the top surface of the box body 11, a sprinkler head 13 and a wire inlet trough 15 being provided at the bottom of the box body 11, a plurality of sprinkler heads 13 being evenly distributed on the bottom surface of the box body 11, and the wire inlet trough 15 being located at one end of the bottom surface of the box body 11;

[0035] The tested mechanism 3 is provided below the box body 11. The tested mechanism 3 includes a cabinet 31 provided 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.

[0036] 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 mounted on the output end of the hydraulic telescopic rod 12. A main rod 42 is mounted on the upper end of the side of the side plate 41, and a secondary rod 44 is mounted on the top surface of the main rod 42. A conductive rod 46 is mounted inside the secondary rod 44, and a touch plate 47 is mounted on the end of the conductive rod 46. A connecting tube 491 is mounted on the side of the bottom end of the side plate 41;

[0037] 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 .

[0038] The rotating mechanism 1 also includes a rotating groove 14 provided 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 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 block 19 is 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.

[0039] 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, and a clamping gear 23 is provided inside the shell 21. The clamping gear 23 is installed at the output end of the motor 22, and two arms 24 are connected in an alternating sliding manner in the shell 21, and the clamping gear 23 is engaged with the two arms 24 at the same time, and a clamping claw 25 is fixed to the outer end of each arm 24.

[0040] 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.

[0041] 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 live wire harness 32 from the wire inlet groove 15 into the box body 11, so that the live wire harness 32 contacts the conductive block 51. Next, the hydraulic telescopic rod 12 is activated. The hydraulic telescopic rod 12 (hydraulic telescopic rod 12 is a multi-stage telescopic rod) drives the detection mechanism 4 to move. The main rod 42 and auxiliary rod 44 on the upper side of the side panel 41 are inserted into the interior of the box body 11, and finally the contact 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. Through the contact plate 47 with the conductive block 51 and the conductive rod 46 inside the auxiliary rod 44, the power harness 32 and the ground wire 33 are connected to the detection device circuit, forming a circuit. The side panel 41 is equipped with relevant testing equipment for insulation testing and leakage detection of the distribution cabinet. After the circuit is connected, the insulation testing equipment and leakage detection equipment inside the side panel 41 test whether the insulation and leakage of the cabinet 31 are qualified.

[0042] After the cabinet 31 passes the insulation test and leakage test, an external water source sprays water through the sprinkler nozzle 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.

[0043] 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 shortened, the workload of the operator 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.

[0044] 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 further includes a wire clamping block 52 and a second spring 53 installed inside the box body 11 . The wire clamping block 52 is elastically connected to the inside of the box body 11 through the second spring 53 .

[0045] A release mechanism 6 is provided inside the box body 11. 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. A baffle 67 is installed in the box body 11 at the other end of the lever 62.

[0046] In order to improve the connection stability between the wire 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 the 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 wire harness 32 is inserted into the box body 11 from the wire inlet groove 15, the wire clamping block 52 pushes the wire 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 wire harness 32, so that the electrical connection between the wire 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 wire harness 32 are both concave arc surfaces, which can increase the contact area with the wire harness 32 and further improve the stability of the line connection.

[0047] 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 clash with the block 64 at one end of the lever 62 during the movement. Since the inclined surface of the push block 49 clashes with the 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 block 64 and compresses the first spring 48. After the push block 49 passes over the block 64, under the elastic force of the first spring 48, the push block 49 pops out from the main rod 42 again.

[0048] Since the cabinet body 31 is wetted by water during the leakage detection process, it is necessary to remove the water stains on the surface of the cabinet body 31 as much as possible after the detection is completed. Therefore, after the detection is completed, the connection between the detection mechanism 4 and the power harness 32 and the ground wire 33 is released to drive the cabinet body 31 to rotate, thereby preliminarily removing the water stains on the surface of the cabinet body 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 contacts the block 64, and exerts a force on the 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 engage 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 gear ring 18 contacts the ratchet gear 17 through the first torsion spring 191. At this time, the rotation of the gear ring 18 can drive the ratchet gear 17 to rotate through the limit block 19 (during the sliding of the main rod 42 into the box body 11, the first rack 43 also drives the gear ring 18 to rotate, but in this process the gear ring 18 rotates clockwise, and the limit block 19 does not contact the ratchet gear 17, so it does not drive the ratchet gear 17 to rotate, and the gear ring 18 rotates 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 clamping claw 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 prevent the power harness 32 and the ground wire 33 from being pulled during the rotation of the cabinet 31, so that the mechanism 3 to be tested can rotate better.

[0049] 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. The drying mechanism 7 includes connecting arms 71 symmetrically fixed on both sides of the box body 11. A cylinder 72 is installed at the end of the connecting arm 71. A shaft 73 is rotatably connected inside the cylinder 72. A number of blowing nozzles 74 are equidistantly installed on the shaft 73, and the several blowing nozzles 74 protrude from the bottom surface of the cylinder 72. Each blowing nozzle 74 is connected to a hot air pipe 75.

[0050] 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. A number 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 protrusions 792 are symmetrically fixed on both sides of the bottom end of each lifting rod 79. An adjustment frame 793 is installed on the top surface of each blowing nozzle 74. The two protrusions 792 on each lifting rod 79 are slidably connected to the corresponding adjustment frame 793.

[0051] During the rotation of the cabinet 31, hot air enters each blowing nozzle 74 through the hot air pipe 75, and is then sprayed from the blowing nozzle 74 toward the surface of the cabinet 31, evaporating the remaining water stains on the surface of the cabinet 31 and drying the water stains on the surface of the cabinet 31. The rotation of the cabinet 31 can reduce the dead corners covered by the hot air, allowing as much hot air as possible to cover the surface of the cabinet 31, accelerating the evaporation of water stains, and improving the drying efficiency. As the main rod 42 slides out of the box body 11, it also drives the second racks 45 on both sides of the auxiliary rod 44 to intermittently contact the long rod 76. Each time it contacts the long rod 76, the long rod 76 slides toward the inside of the connecting arm 71, compressing the fourth spring 77 and pushing the triangular plate 78 to slide toward the inside of 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 adjustment frame 793. The blowing nozzle 74 swings in the cylinder 72 with the shaft 73 as the rotation axis, causing the blowing direction of the blowing nozzle 74 to change, thereby increasing the range of hot air coverage and further improving the drying effect. As the lifting rod 79 presses down the blowing nozzle 74, the protruding column 792 slides in the adjustment frame 793.

[0052] 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 based on the above description. It is impossible to list all the implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
