Description

Technical Field

[0001] This utility model relates to the field of switchgear monitoring technology, and more specifically to an adjustable monitoring mechanism suitable for switchgear. Background Technology

[0002] Switchgear, as the core equipment in power transmission and distribution systems, undertakes important functions such as power distribution, circuit protection, equipment control and condition monitoring. It is widely used in substations, industrial plants, commercial buildings and other fields. Real-time monitoring of switchgear has become a key link in ensuring power grid stability and preventing equipment failures.

[0003] A search revealed Chinese patent CN214154682U, which discloses a monitoring device for an intelligent switch cabinet. This device rotates a handle, causing a rotating rod to rotate, which in turn rotates a second bevel gear. The second bevel gear then drives a first bevel gear to rotate, causing a threaded rod to rotate simultaneously. As the threaded rod rotates, a sleeve block moves a connecting block downwards on the outer surface of the threaded rod, thus moving the monitoring unit downwards as well. However, the monitoring unit can only move up and down via the threaded rod to monitor the inside of the cabinet; it cannot rotate, leaving the inner edges of the cabinet unmonitored, creating blind spots and posing a potential safety hazard. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable monitoring mechanism suitable for switch cabinets to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an adjustable monitoring mechanism suitable for switch cabinets, including a cabinet body, side plates on both sides of the cabinet body, and square openings on both side plates. A fixed box is fixedly connected to one side of each side plate, outside the square opening, to cover the square opening and communicate with the interior of the cabinet body. A linear motor module is fixedly connected to one inner wall of the fixed box. A connecting frame is fixedly connected to one side of the moving part of the linear motor module. A rotating shaft is rotatably connected to one outer wall of the connecting frame via a bearing. A connecting block is fixedly connected to one end of the rotating shaft. An L-shaped plate is fixedly connected to the outer circumference of the connecting block. A notch is opened at one end of the L-shaped plate. A rotating plate is rotatably connected between the two inner walls of the notch. A monitoring camera is fixedly connected to one end of the rotating plate. A drive motor for rotating the rotating shaft along the axial direction is fixedly connected to one inner wall of the connecting frame.

[0006] As a further embodiment of this utility model, the L-shaped plate has a sliding opening, and an I-shaped slider is slidably connected inside the sliding opening. A square telescopic rod is fixedly connected to one side of the I-shaped slider, and a U-shaped frame is fixedly connected to one side of the rotating plate. Two symmetrical fixing plates are fixedly connected to the outer wall of one side of the U-shaped frame. A connecting rod is rotatably connected between the fixing plates through a bearing, and one end of the square telescopic rod is fixed to the outer circumference of the connecting rod.

[0007] As a further embodiment of this utility model, a miniature electric push rod is fixedly connected to one side of the inner wall of the slide opening, the output end of the miniature electric push rod is fixed to one side of the I-shaped slider, and a fixing frame for fixing the miniature electric push rod is fixedly connected between the two inner walls of the slide opening.

[0008] As a further embodiment of this utility model, two symmetrical electromagnetic pin locks are fixedly connected to one inner wall of the connecting frame, and multiple equally spaced insertion holes are opened on both sides of the fixing box, with the cylindrical locking tongue of the electromagnetic pin lock inserted into one of the insertion holes.

[0009] As a further embodiment of this utility model, the outer circumference of the rotating plate and the notched rotating contact surface has a first mating surface with an involute thread shape, and the inner circumference of the notched and the rotating plate rotating contact surface has a second mating surface that meshes with the first mating surface. The space between the second mating surface and the first mating surface is filled with a viscoelastic damping medium.

[0010] As a further embodiment of this utility model, the connecting frame is always inside the fixed box, and the monitoring camera extends slightly out of the square opening and into the cabinet.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model features a rotating plate and an L-shaped plate with a rotatable design for mounting a monitoring camera, allowing for multi-angle monitoring of the cabinet's interior. It can monitor not only the central area of ​​the cabinet but also areas near the edges, providing comprehensive monitoring without blind spots.

[0013] 2. This utility model uses a miniature electric push rod to change the angle between the rotating plate and one side of the L-shaped plate during its extension and retraction. When the angle increases, it monitors the middle position inside the cabinet, and when the angle decreases, it monitors the position near the edge inside the cabinet, effectively increasing the monitoring range.

[0014] 3. This utility model uses an electromagnetic pin lock and a socket in combination.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Reference Figures 1-4This utility model provides an adjustable monitoring mechanism suitable for switch cabinets, including a cabinet body 1. Side plates 2 are provided on both sides of the cabinet body 1, and square openings 3 are provided on each side plate 2. A fixing box 4, which covers the square openings 3 and communicates with the interior of the cabinet body 1, is bolted to one side of each side plate 2, outside the square openings 3. A linear motor module 5 is bolted to the inner wall of one side of the fixing box 4. A connecting frame 6 is bolted to the moving side of the linear motor module 5. A rotating shaft is rotatably connected to the outer wall of one side of the connecting frame 6 via a bearing. 7. One end of the rotating shaft 7 is fixedly connected to a connecting block 8 by bolts. An L-shaped plate 9 is fixedly connected to the outer circumference of the connecting block 8 by bolts. One end of the L-shaped plate 9 has a notch 10. A rotating plate 11 is rotatably connected between the inner walls of the two sides of the notch 10. The outer circumference of the rotating contact surface between the rotating plate 11 and the notch 10 has a first mating surface with an involute thread. The inner circumference of the rotating contact surface between the notch 10 and the rotating plate 11 has a second mating surface that meshes with the first mating surface. The space between the second mating surface and the first mating surface is filled with a viscoelastic damping medium. One end of the rotating plate 11 is fixedly connected to a monitoring camera 12 by bolts. A drive motor 13, which causes the rotating shaft 7 to rotate axially, is fixedly connected to the inner wall of one side of the connecting frame 6 by bolts. The connecting frame 6 is always inside the fixed box 4. The monitoring camera 12 extends slightly out of the square opening 3 into the cabinet 1. In use, the linear motor module 5 first drives the connecting frame 6 to move up and down in the fixed box 4, thereby monitoring the inside of the cabinet 1 in real time. When it is necessary to check the inner edge of the cabinet 1, the drive motor 13 is started, which in turn drives the L-shaped plate 9 to rotate through the rotating shaft 7 and the connecting block 8 at its end. During the rotation of the L-shaped plate 9, the rotating plate 11 on it rotates synchronously, thereby changing the monitoring angle of the monitoring camera 12 at its end. By making the rotating plate 11 and the L-shaped plate 9 with the monitoring camera 12 rotatable, the inside of the cabinet 1 can be monitored from multiple angles. It can monitor not only the middle position inside the cabinet 1, but also the position near the edge inside the cabinet 1, so that the inside of the cabinet 1 can be monitored without blind spots.

[0022] In this invention, an L-shaped plate 9 has a sliding opening 16, within which an I-shaped slider 17 is slidably connected. A square telescopic rod 18 is bolted to one side of the I-shaped slider 17. A U-shaped frame 19 is bolted to one side of the rotating plate 11. Two symmetrical fixing plates 20 are bolted to the outer wall of one side of the U-shaped frame 19. A connecting rod 21 is rotatably connected between the fixing plates 20 via a bearing. One end of the square telescopic rod 18 is fixed to the outer circumference of the connecting rod 21. When it is necessary to change the angle between the rotating plate 11 and one side of the L-shaped plate 9 to further change the monitoring angle of the surveillance camera 12, the miniature electric push rod 22 is activated to retract or extend. During the extension and retraction of the miniature electric push rod 22, the connected I-shaped slider 17 slides along the sliding opening 16. During the sliding of the I-shaped slider 17, it... The square telescopic rod 18 on it moves. Since the square telescopic rod 18 is rotatably connected to the two fixed plates 20, the rotating plate 11 and the notch 10 are also rotating. When the mini electric push rod 22 extends, the angle between the rotating plate 11 and the L-shaped plate 9 increases. At the same time, the square telescopic rod 18 extends, and the monitoring camera 12 monitors the middle position inside the cabinet 1. When the mini electric push rod 22 retracts, the angle between the rotating plate 11 and the L-shaped plate 9 decreases. At the same time, the square telescopic rod 18 retracts, and the monitoring camera 12 monitors the edge position inside the cabinet 1. By using the mini electric push rod 22, the angle between the rotating plate 11 and the L-shaped plate 9 on one side is changed during its extension and retraction. When the angle increases, the middle position inside the cabinet 1 is monitored. When the angle decreases, the position near the edge inside the cabinet 1 is monitored, effectively increasing the monitoring range.

[0023] In this utility model, a miniature electric push rod 22 is fixedly connected to one side of the inner wall of the slide 16 by bolts. The output end of the miniature electric push rod 22 is fixed to one side of the I-shaped slider 17. A fixing frame 23 for fixing the miniature electric push rod 22 is fixedly connected between the two inner walls of the slide 16 by bolts.

[0024] In this invention, two symmetrical electromagnetic locks 14 are fixedly connected to the inner wall of one side of the connecting frame 6 by bolts. Multiple equally spaced insertion holes 15 are opened on both sides of the fixing box 4. The cylindrical locking tongue of the electromagnetic lock 14 is inserted into one of the insertion holes 15. Before the linear motor module 5 is started to drive the connecting frame 6 to move, the electromagnetic lock 14 is first started to retract the locking tongue, so that it is disengaged from the insertion hole 15. After the connecting frame 6 has moved, the electromagnetic lock 14 is restarted to extend the locking tongue, so that it is re-inserted into one of the insertion holes 15. By using the electromagnetic lock 14 and the insertion hole 15 in cooperation, after the connecting frame 6 has moved, the locking tongue of the electromagnetic lock 14 is extended into the insertion hole 15, so that the connecting frame 6 and the fixing box 4 can be kept locked, preventing the connecting frame 6 from sliding on its own.

[0025] The use of this utility model involves the following steps:

[0026] S1: In use, the linear motor module 5 first drives the connecting frame 6 on it to move up and down in the fixed box 4, thereby monitoring the inside of the cabinet 1 in real time. When it is necessary to check the inner edge of the cabinet 1, the drive motor 13 is started, which in turn drives the L-shaped plate 9 to rotate through the rotating shaft 7 and the connecting block 8 at its end. During the rotation of the L-shaped plate 9, the rotating plate 11 on it rotates synchronously, thereby changing the monitoring angle of the monitoring camera 12 at its end.

[0027] S2: When it is necessary to change the angle between the rotating plate 11 and the L-shaped plate 9 to further change the monitoring angle of the monitoring camera 12, the mini electric push rod 22 is activated to retract or extend. During the extension and retraction of the mini electric push rod 22, the I-shaped slider 17 connected to it will slide along the sliding opening 16. During the sliding of the I-shaped slider 17, the square telescopic rod 18 on it will move. Since the square telescopic rod 18 is rotatably connected to the two fixed plates 20, the rotating plate 11 and the notch 10 are also in a rotating state. When the mini electric push rod 22 extends, the angle between the rotating plate 11 and the L-shaped plate 9 will increase. At the same time, the square telescopic rod 18 extends, and the monitoring camera 12 monitors the middle position inside the cabinet 1. When the mini electric push rod 22 retracts, the angle between the rotating plate 11 and the L-shaped plate 9 will decrease. At the same time, the square telescopic rod 18 retracts, and the monitoring camera 12 monitors the edge position inside the cabinet 1.

[0028] S3: Before starting the linear motor module 5 to move the connecting frame 6, first start the electromagnetic pin lock 14 to retract the locking tongue so that it is no longer in contact with the socket 15. After the connecting frame 6 has moved, restart the electromagnetic pin lock 14 to extend the locking tongue so that it is reinserted into one of the sockets 15.

[0029] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
