[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0037] Embodiment 1

[0038] See also Figure 1-Figure 14 The present invention provides an intelligent online monitoring device for a switch cabinet, comprising a movable plate 1 which is slidably matched with a frame located in the switch cabinet body and has an inner cavity therein, a monitoring sensor 2 is slidably matched on the movable plate 1, a chain 3 is rotatably connected inside the movable plate 1, a rotating shaft 4 is connected to the chain 3, a movable plate 5 is slidably matched on the rotating shaft 4, a limiter is provided inside the movable plate 1, the limiter is used for the chain 3 to continuously rotate, and drives the movable plate 5 and the monitoring sensor 2 to reciprocate horizontally, and rolling wheels 6 are rotatably connected at both ends of the movable plate 1;

[0039] It also includes: a rotating plate 7 located at one end of the chain 3, a self-rotating rod 8 is fixedly connected to the middle of the rotating plate 7, a pressing frame 9 is pressed on the self-rotating rod 8, and a rotating member is provided at the end of the movable plate 1. The rotating member is used to rotate the rotating plate 7 when the rotating shaft 4 passes through the end of the chain 3 and the moving plate 5 acts on the pressing frame 9, thereby acting on the two rolling wheels 6 to move the movable plate 1 along the frame gap of the switch cabinet;

[0040] In the present application, the monitoring sensor 2 is first moved from one end (for example, the left end) to the other end (the right end) by means of a horizontally movable monitoring sensor 2 (the vertical height of the movable plate 1 remains unchanged), thereby completing the monitoring of the electrical components at the same horizontal position one by one;

[0041] Then the monitoring sensor 2 is slid toward the left end. In the initial process of sliding from the right end to the left end, the rotating shaft 4 acts on the rotating plate 7 to make the self-rotating rod 8 rotate to adjust the angle, thereby realizing the upward or downward movement adjustment of the movable plate 1 to enter another horizontal position;

[0042] When the preliminary process of sliding from the right end to the left end is completed, in the subsequent process of the monitoring sensor 2 sliding from the right end to the left end, the monitoring sensor 2 that adjusts the vertical height moves horizontally to monitor another electrical component at a horizontal position;

[0043] This method helps to ensure the comprehensiveness of monitoring and is easy to operate and has strong adaptability.

[0044] In the present application, the space occupation is reduced by switching the position of the movable plate 1, and when monitoring is not needed, the movable plate 1 is stored at the top or bottom of the switch cabinet.

[0045] The limiting member includes a slider 10 rotatably connected to the rotating shaft 4, a sliding groove 11 slidably matched with the slider 10 is provided on the moving plate 5, and a stabilizing member for keeping the moving plate 5 sliding horizontally is also provided on the moving plate 5;

[0046] The stabilizing member includes a connecting plate 12 and a control rod 13 connected and fixed to the movable plate 5. Two movable grooves 14 are provided through the movable plate 1. The two movable grooves 14 are respectively slidably matched with the connecting plate 12 and the control rod 13. The connecting plate 12 is connected to the monitoring sensor 2.

[0047] By manually sliding the control rod 13 along the moving groove 14 (reciprocatingly, sliding from one end of the moving groove 14 to the other end, and then sliding from the other end back to one end, and so on), the moving plate 5 is moved, so that the monitoring sensor 2 is moved horizontally, and the horizontal direction of the position of the monitoring sensor 2 is adjusted, so that the monitoring sensor 2 monitors the discharge and other electrical test data of multiple electrical components of the switch cabinet one by one;

[0048] On the other hand, the chain 3 is rotated, the shaft 4 and the slider 10 make a circular motion (the trajectory of the circular motion is consistent with the shape of the chain 3), so that the movable plate 5 can only make a horizontal reciprocating motion in the movable plate 1, and the slider 10 makes an up-and-down reciprocating motion in the sliding groove 11;

[0049] The reciprocating moving plate 5 acts on the pressing frame 9 to open the pressing frame 9, and then the rotating shaft 4 acts on the rotating plate 7 to rotate the gap between the rotating rod 8, the rotating plate 7 and the rolling wheel 6, thereby realizing the vertical adjustment of the position of the monitoring sensor 2.

[0050] The two movable grooves 14 are inclined, and the connecting plate 12 and the control rod 13 are inclined. The movable grooves 14, the connecting plate 12 and the control rod 13 are inclined to prevent dust from falling in. The length of the movable groove 14 is greater than the distance between the outer ends of the two wheels, that is, greater than the distance between the two ends of the chain 3, to ensure that the chain 3 rotates multiple times.

[0051] The rotating member includes a first connecting plate 15 connected and fixed to the inner cavity wall of the movable plate 1, and an elastic member is provided on the first connecting plate 15 to press against the pressing frame 9. The rotating rod 8 rotates in the movable plate 1, and the cross-section of the rotating rod 8 is rectangular. A plurality of embedded grooves 16 that slide with the rotating shaft 4 are provided on the rotating plate 7. The end of the rotating rod 8 is connected and fixed to the central axis of the rolling wheel 6. Sliding members are provided at both ends of the movable plate 1 to cooperate with the two rolling rolling wheels 6 to enable the movable plate 1 to move smoothly.

[0052] When the moving plate 5 and the rotating shaft 4 gradually move to the end of the chain 3, the moving plate 5 first presses against the pressing frame 9, so that the pressing frame 9 is away from the self-rotating rod 8, thereby releasing the restriction on the self-rotating rod 8;

[0053] Then the rotating shaft 4 enters one of the embedding grooves 16. During the continuous operation of the chain 3, the rotating shaft 4 moves in the embedding groove 16, so that the rotating plate 7, the self-rotating rod 8 and the rolling wheel 6 rotate 1 / 4 of a circle. During this process, the pressing frame 9 is always away from the self-rotating rod 8.

[0054] Finally, the rotating shaft 4 is separated from the embedding groove 16, and the pressing frame 9 presses and contacts the rotating rod 8 again, and the rotating rod 8 after the angle adjustment is pressed and fixed.

[0055] In the present application, when the monitoring sensor 2 moves from one side to the other and then performs a reverse reset (i.e., the monitoring of multiple horizontally distributed electrical components at the same vertical height is completed, and the electrical components at the lower or upper position need to be firmly monitored), the rolling wheel 6 rotates 1 / 4 circle and cooperates with the sliding part to move the monitoring sensor 2 up or down a certain distance and maintain this position to ensure the comprehensiveness of the monitoring.

[0056] The elastic member includes two symmetrically distributed telescopic rods 17 (to ensure the stable movement of the pressing frame 9), a compression spring 18 is provided between the two telescopic rods 17, and both ends of the compression spring 18 and the telescopic rod 17 are respectively connected to the first connecting plate 15 and the pressing frame 9;

[0057] The movable plate 5 that performs reciprocating motion (relative to the chain 3 and the movable plate 1, it only performs reciprocating motion in the horizontal direction) presses against the pressing frame 9, causing the pressing frame 9 to move away from the rotating rod 8, compressing the compression spring 18, and then the rotating shaft 4 enters the embedding groove 16 to complete the rotation adjustment of the rotating rod 8. Finally, when the rotating shaft 4 is away from the embedding groove 16 and the movable plate 5 is away from the pressing frame 9, under the action of the compression spring 18, the pressing frame 9 ensures the position of the adjusted rotating rod 8. In this way, the gap of the rolling wheel 6 can rotate smoothly at a certain angle, thereby completing the smooth upward or downward movement of the gap of the movable plate 1, so that the gap can smoothly adjust the position of the monitoring sensor 2 to ensure the comprehensiveness and stability of the monitoring.

[0058] The pressing frame 9 is assembled by a U-shaped plate and two L-shaped plates. In this structure, when the pressing frame 9 is away from the rotating rod 8, the position of the rotating rod 8 corresponds to the position of the two L-shaped plates, so that the rotation of the rotating rod 8 will not be affected by the pressing frame 9. When the rotation position of the rotating rod 8 is adjusted, the rotating rod 8 is automatically pressed and fixed by the U-shaped plate.

[0059] The sliding member includes a U-shaped limit plate 19 connected and fixed to the frame of the switch cabinet, a matching plate 20 that is rollingly matched with the rolling wheel 6 is fixedly connected inside the U-shaped limit plate 19, and a rotating plate 21 that is rotatably connected between the edges of the two rolling wheels 6 is obliquely distributed. When one of the rolling wheels 6 rotates 1 / 4 of a circle in the gap under the action of the self-rotating rod 8, the other rolling wheel 6 is rotated at the same time under the action of the rotating plate 21, and the two rolling wheels 6 rotate in opposite clockwise directions, so that the two rolling wheels 6 (a part of the rolling wheels 6 passes through the movable plate 1 and matches with the matching wheel) move upward or downward on the matching plate 20 at the same time, so that the movable plate 1 moves upward or downward smoothly along the U-shaped limit plate 19, thereby adjusting the monitoring position;

[0060] And the movable plate 1 moves upward or downward, depending on the moving direction of the chain 3;

[0061] The rolling wheel 6 and the matching wheel are preferably gears and toothed plates to make the meshing motion more stable.

[0062] A second connecting plate 22 fixedly connected to the movable plate 1 is provided between the rotating wheels of the two chains 3 and the rotating plate 21. The second connecting plate 22 is rotatably connected to the central axis of the rotating wheels of the chains 3. The setting of the second connecting plate 22 ensures the smooth operation of the chains 3 and will not conflict with the positions of the rotating plate 21 and the rolling wheel 6, resulting in motion interference.

[0063] Embodiment 2

[0064] See also Fig.15 In the second embodiment, a motor 23 is fixedly connected inside the movable plate 1, and the output shaft of the motor 23 is fixedly connected to the central axis of one of the rolling wheels 6 (the rolling wheel 6 at a position away from the rotating plate 7). This method adds automatic adjustment of the position of the monitoring sensor 2, and combined with the manual adjustment control lever 13, the adjustment mode can be automatically switched, thereby increasing applicability.
