[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0028] Example 1, referring to Figure 1 - Figure 2 The first embodiment of the present invention provides a sealed redundant cavity type PLC monitoring and control cabinet. This device includes: a control cabinet 1; a cable management unit 2 fixedly installed on the control cabinet 1 for guiding and laying out signal cables; and an installation unit 3 fixedly installed on the cable management unit 2, the installation unit 3 being fixedly connected to the control cabinet 1 for adjusting the layout and cabling of signal cables.
[0029] The cable routing unit 2 further includes a cable routing assembly 21 slidably mounted on the control cabinet 1 for guiding the signal cable; a fixing assembly 22 fixedly mounted on the cable routing assembly 21 for clamping and fixing the signal cable guided by the cable routing assembly 21; and a guide assembly 23 fixedly mounted on the fixing assembly 22 for uniformly sorting and guiding the fixed cable.
[0030] Furthermore, the installation unit 3 includes an installation component 31 fixedly installed on the control cabinet 1. The installation component 31 is fixedly connected to the cable assembly 21 and slidably connected to the guide component 23, and works with the cable assembly 21 and the guide component 23 to divide and guide the multi-strand signal cables.
[0031] During use, the signal cables to be connected are first guided and wound around the cable tray 21. The cable tray 21 forces a multi-channel, multi-zone wiring method for the signal cables, allowing for the classification, labeling, and installation of multiple different signal cables, making the arrangement of various types of signal cables clear and easy to understand. Simultaneously, utilizing the multi-channel differentiation function of the cable tray 21, when a problem occurs in a particular signal cable, accurate detection and alarm can be performed directly, facilitating precise identification of the signal cable requiring repair during maintenance. Furthermore, the cable tray 21 can also isolate multiple signal cables, preventing signal interference between cables. Interference is prevented, and a single cable failure also prevents other cables from being affected. With the cooperation of the fixing component 22, the signal cable can only move to one end during installation, ensuring the neatness of the installation and reinforcing the cable to prevent displacement. Through the cooperation of the guide component 23 and the mounting component 31, the signal cable can be freely laid out in the PLC monitoring and control cabinet, realizing multi-directional wiring. This solves the problems of messy wiring, centralized bundling, cumbersome maintenance, low efficiency, difficulty in rewiring, high difficulty in maintenance and testing, poor heat dissipation and short service life of traditional PLC control cabinets, and improves the stability, safety and convenience of the control cabinet operation.
[0032] Example 2, refer to Figure 1 - Figure 6 This is the second embodiment of the present invention, which differs from the first embodiment in that: the cable assembly 21 includes a connecting guide plate 211 slidably mounted on the control cabinet 1 for uniformly guiding the signal cables; a control component 212 fixedly mounted on the connecting guide plate 211; connecting plates 213 fixedly mounted on both sides of the control component 212; and a network cable detector 214 fixedly mounted on the connecting plate 213. The control component 212, together with the connecting plate 213 and the network cable detector 214, detects the signal cables passing through inside. If a problem occurs in the signal cable, the network cable detector 214 will issue an alarm, thereby accurately locating the problem location.
[0033] Compared to Embodiment 1, the connecting guide plate 211 is further provided with a guide groove 215 inside for guiding and conveying the cable; an isolation plate 216 is fixedly installed inside the guide groove 215, and the isolation plate 216 is fixedly connected to the connecting guide plate 211 for separating multi-strand signal cables.
[0034] Furthermore, a sealing aluminum sleeve 217 is fixedly installed inside the guide groove 215, and the sealing aluminum sleeve 217 is fixedly connected to the isolation plate 216 and the connecting guide plate 211. It is used to cooperate with the isolation plate 216 to divide the multi-strand signal cables into sections. At the same time, the sealing aluminum sleeve 217 can prevent signal interference between the multi-strand cables.
[0035] Furthermore, the fixing assembly 22 includes a connector 221 fixedly mounted on the connecting guide plate 211 for connecting the rotating member 222; the rotating member 222 fixedly mounted on the connector 221 for rotating in conjunction with the rotating column 224; and the rotating column 224 rotatably mounted on the rotating member 222, and the rotating column 224 is rotatably connected to the connector 221, and rotates in conjunction with the fixing plate 225 to clamp and fix the signal cable.
[0036] Furthermore, a fixing plate 225 is fixedly installed on the rotating column 224 to clamp and fix the cable, so that the cable can only enter and exit in one direction; a coil spring 223 is fixedly installed on the inner wall of the rotating part 222, and the coil spring 223 is fixedly connected to the rotating column 224, which works with the rotating column 224 to provide a reverse force to the fixing plate 225.
[0037] Furthermore, the guide assembly 23 includes a U-shaped clamping plate 231 fixedly mounted on the connecting guide plate 211 for guiding and fixing the other end of the cable; a return spring 232 fixedly mounted on the inner wall of the U-shaped clamping plate 231; and a pressing plate 233 fixedly mounted on the other end of the return spring 232, wherein the pressing plate 233 is slidably connected to the U-shaped clamping plate 231, and the return spring 232 cooperates with the pressing plate 233 to uniformly clamp and limit the signal cable inside the U-shaped clamping plate 231 to ensure that the cable can be transported in a uniform direction.
[0038] During use, multiple signal cables are first inserted sequentially into the guide grooves 215 from the side of the connecting guide plate 211. Guided by the guide grooves 215, one end of the signal cable passes through the middle of the fixing plate 225. The multiple guide grooves 215 inside the connecting guide plate 211 can guide the multiple signal cables in sections. Simultaneously, with the cooperation of the isolation plate 216, two signal cables can pass through a single guide groove 215. Furthermore, under the sealing and isolation effect of the sealing aluminum sleeve 217, no signal interference will occur between the multiple cables. In addition, the connecting guide plate 211 has identical guide grooves 215 at both ends, allowing for simultaneous synchronous guidance of output and input cables between multiple connecting guide plates 211 according to the wiring requirements, achieving synchronous wiring of output and input cables and improving the practicality of the wiring.
[0039] The fixing plate 225 is clamped inward by the coil spring 223 inside the rotating column 224 and rotating component 222, so that the fixing plates 225 at both ends can clamp and limit the cable passing through inside, ensuring that the cable can only move in the direction of the fixing plate 225; if it moves in the opposite direction of the fixing plate 225, the fixing plate 225 will directly engage with the outer wall of the cable, and the further it moves, the tighter the engagement. This makes it easy to repair and replace the cable by simply pulling it out from the front, improving the convenience of repair. At the same time, with the cooperation of the network cable detector 214, the cables passing through inside can be detected. If a cable fails, the network cable detector 214 will immediately detect the abnormality. The signal is synchronously transmitted to the connecting plate 213 and the control unit 212, and then an alarm is triggered, enabling maintenance personnel to accurately locate the fault point for repair, thereby improving the repair speed and efficiency. When guiding the cable, the U-shaped clamp 231 uniformly limits the other end of the cable. Through the cooperation of the reset spring 232 and the squeezing plate 233, the cable passing through the U-shaped clamp 231 is clamped to ensure that the cable can be uniformly transported downwards, realizing flexible multi-directional wiring in the control cabinet 1. This solves the problems of messy wiring, centralized bundling, cumbersome maintenance, low efficiency, difficulty in rewiring, high difficulty in maintenance and testing, poor heat dissipation and short service life of traditional PLC control cabinets.
[0040] The remaining structure is the same as that in Example 1.
[0041] Example 3, referring to Figure 1 - Figure 8 This is the third embodiment of the present invention, which differs from the second embodiment in that: the mounting assembly 31 includes an L-shaped fixing member 311 fixedly mounted on the connecting guide plate 211 for connecting the rotating clamp 314; a rotating clamp 314 rotatably mounted inside the L-shaped fixing member 311 for engaging and fixing with the support mounting rod 315; and a support mounting rod 315 fixedly mounted on the control cabinet 1, which is slidably connected to the rotating clamp 314 for cooperating with the cable assembly 21 to achieve fixation and connection.
[0042] Compared to Embodiment 2, this embodiment further includes: an L-shaped fastener 311 with a rotating groove 312 inside to accommodate the rotating retraction action of the rotating clip 314; a spring sheet 313 is slidably installed in the rotating groove 312, with its other end fixedly connected to the rotating clip 314; at the same time, the rotating clip 314 is slidably connected to the rotating groove 312 to realize the rotating return function of the rotating clip 314.
[0043] Furthermore, a limiting member 316 is fixedly installed on the connecting guide plate 211. The limiting member 316 is slidably connected to the support mounting rod 315 and is used to cooperate with the rotating clamp 314 to complete the locking and fixing.
[0044] During use: When the installation position of the connecting guide plate 211 needs to be adjusted, first, press the connecting guide plate 211 into the control cabinet 1, so that the limiting member 316 slides out of the front support mounting rod 315. At the same time, the rotating clip 314 inside the L-shaped fixing member 311 also disengages from the rear support mounting rod 315, simultaneously releasing the fixed state between the rotating clip 314 and the support mounting rod 315. Then, slide the connecting guide plate 211 along the outer wall of the support mounting rod 315 to adjust its installation position, thereby optimizing the wiring layout of the signal cable, realizing various combination wiring, and improving practicality. After the adjustment is completed, pull the connecting guide plate 211 forward so that the limiting member 316 and the rotating clip 314 slide back into the support mounting rod 315 to complete the fixation. At this time, under the positioning cooperation of the spring plate 313, the rotating clip 314 rotates and moves in the rotating groove 312, stably engaging in the support mounting rod 315, completing the fixed installation of the connecting guide plate 211, effectively improving the operational stability, safety, and maintenance convenience of the control cabinet.
[0045] The remaining structure is the same as that in Example 2.
