Detailed Implementation
[0018] The present invention will now be described in more detail with reference to the embodiments.
[0019] like Figs. 1 to 3 As shown, the multi-level fault isolation structure of the switch in this embodiment includes a switch body 1, and a plurality of partition cavities 3 are provided inside the switch body 1. Any two adjacent partition cavities 3 are separated by a partition 2.
[0020] Specifically, each partition cavity 3 is equipped with a main module box 5 and a backup module box 6. The main module box 5 is equipped with a main working module and a monitoring module for monitoring the working status of the main working module. The monitoring module is connected to a host computer. The backup module box 6 is equipped with a backup working module. The partition cavity 3 is also equipped with a switching mechanism 4 for switching the work of the backup working module when the main working module fails.
[0021] The main working modules in this embodiment include, but are not limited to, a power module, a control module, an interface module, a switching module, and a security module.
[0022] The backup working modules in this embodiment include, but are not limited to, a backup power module corresponding to the power module, a backup control module corresponding to the control module, a backup interface module corresponding to the interface module, a backup switching module corresponding to the switching module, and a backup security module corresponding to the security module.
[0023] The monitoring module includes temperature, voltage, and current sensors, which are mainly used to monitor whether the main working module is abnormal. If an abnormality occurs, the host computer controls the switching mechanism 4 to switch to the corresponding backup working module. That is, through the multi-level redundancy structure, when the main working module is abnormal, it can switch to the corresponding backup working module in time, without affecting the operation of the switch, and significantly improving the reliability of the switch.
[0024] Furthermore, the switching mechanism 4 includes a pair of support frames 11 spaced apart in the partition cavity 3. A movable rod 8 is slidably installed between the two support frames 11. Both ends of the movable rod 8 slide through the two support frames 11 and are fixedly connected to protective covers 10. One protective cover 10 is placed on the upper end of the spare module box 6, and the main module box 5 is placed on the side of the other protective cover 10 away from the fixed frame 9. When the main module box 5 is working normally, the protective cover 10 is placed on the upper end of the spare module box 6, which can protect the components inside the spare module box 6 from dust, etc., while the main module box 5 is not covered by the protective cover 10, thus meeting the heat dissipation requirements.
[0025] A reciprocating motion mechanism for driving the moving rod 8 to move when the main working module fails is also installed between the two support frames 11. A pressing rod 17 is vertically fixed to the moving rod 8. A switching button 16 is provided on the inner wall of the partition 2 to cooperate with the moving pressing rod 17 and to switch the work of the backup working module.
[0026] Specifically, the reciprocating motion mechanism includes a rotating rod 12, an inclined plate 13, a moving frame 14, and a connecting rod 15. Two moving frames 14 are provided and fixedly sleeved on the moving rod 8 at intervals. The connecting rod 15 is installed between the two moving frames 14 and is arranged parallel to each other below the moving rod 8. The rotating rod 12 is rotatably installed between the two fixed frames 9 and is arranged parallel to each other below the connecting rod 15. The inclined plate 13 is arranged obliquely and is fixedly sleeved with the rotating rod 12. The top of the inclined plate 13 is rotatably sleeved with the connecting rod 15. A drive motor (not shown in the figure) for driving the rotating rod 12 to rotate is also installed on the fixed frame 9. The drive motor is connected to the upper electromechanical unit.
[0027] When the main working module malfunctions, the host computer receives a fault signal from the monitoring module and controls the start of the drive motor. The start of the drive motor drives the rotating rod 12 to rotate, which in turn drives the inclined plate 13 to rotate. Since the inclined plate 13 is set at an angle relative to the rotating rod 12, the edge of the inclined plate 13 will move laterally when the inclined plate 13 moves. Therefore, the inclined plate 13 can drive the moving rod 8 to move laterally. When the moving rod 8 moves laterally, one of the protective covers 10 gradually covers the main module box 5, while the other protective cover 10 gradually moves away from the spare module box 6.
[0028] At the same time, when the moving rod 8 moves laterally, it will drive the pressing rod 17 to move horizontally. During the movement of the pressing rod 17, the free end of the pressing rod 17 will press and press the switching button 16 set on the partition 2. The switching button 16 will put the standby working module into use. During the process of the standby working module being put into use, the protective cover 10 will slowly open to meet the heat dissipation requirements of the standby working module. At the same time, the main working module is covered by the protective cover 10, waiting for maintenance personnel to perform maintenance. When the maintenance personnel open the switch body 1, they can see the covered main working module at a glance, which can improve maintenance efficiency.
[0029] Furthermore, a support frame 11 is vertically fixed to the bottom of the fixed frame 9. The support frame 11 has an inverted T-shaped structure, which can improve the stability of the fixed frame 9.
[0030] Furthermore, both the main module box 5 and the spare module box 6 are provided with a slot 7 at the top, and the bottom of the protective cover 10 is provided with a flexible sealing ring that matches the slot 7, which can improve the dustproof effect of the main module box 5 and the spare module box 6.
[0031] The working principle of this utility model is as follows: When the main working module malfunctions, the host computer receives a fault signal from the monitoring module and controls the start of the drive motor. The start of the drive motor drives the rotating rod 12 to rotate, and the rotation of the rotating rod 12 will drive the inclined plate 13 to rotate. Since the inclined plate 13 is set at an angle relative to the rotating rod 12, when the inclined plate 13 moves, the edge of the inclined plate 13 will move laterally. Therefore, the inclined plate 13 can drive the moving rod 8 to move laterally. When the moving rod 8 moves laterally, one of the protective covers 10 gradually covers the main module box 5, while the other protective cover 10 gradually moves away from the spare module box 6.
[0032] At the same time, when the moving rod 8 moves laterally, it will drive the pressing rod 17 to move horizontally. During the movement of the pressing rod 17, the free end of the pressing rod 17 will press and press the switching button 16 set on the partition 2. The switching button 16 will put the standby working module into use. During the process of the standby working module being put into use, the protective cover 10 will slowly open to meet the heat dissipation requirements of the standby working module. At the same time, the main working module is covered by the protective cover 10, waiting for maintenance personnel to perform maintenance. When the maintenance personnel open the switch body 1, they can see the covered main working module at a glance, which can improve maintenance efficiency.
