[0002] With the rapid development of industrial automation, natural gas power stations, as important nodes in energy supply, are receiving increasing attention for their operational efficiency and safety. As the core of the power station control system, the rationality of the PLC (Programmable Logic Controller) cabinet wiring directly affects the stability and reliability of the entire system. In natural gas power stations, the PLC cabinets used require reasonable wiring to support the work in that area.
[0003] For example, the utility model application with application number CN202421349856.5 discloses a wiring optimization device for a PLC cabinet in a natural gas station, including a cabinet and several terminals. An installation frame is fixedly connected to the bottom of the cabinet, and several terminals are fixedly installed in the installation frame. A wiring hole corresponding to the number of terminals is opened on the top side of the installation frame, and a distinguishing component is provided on the top side of the installation frame.
[0004] However, the above-mentioned device only sets up a wiring optimization device at the bottom of the cabinet. The cables still need to be routed and properly wired inside the cabinet. Existing technology usually uses hollow junction boxes to store redundant cables in the junction boxes between components. However, due to the large number of cables, the cables are prone to getting tangled during maintenance and cable replacement, which increases maintenance time and workload.
[0005] Therefore, those skilled in the art have improved upon the existing technology and proposed a natural gas PLC cabinet. Utility Model Content

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0008] A natural gas PLC cabinet includes a cabinet body, within which multiple sets of wiring box assemblies for storing wire harnesses are installed. Each wiring box assembly includes a box body and a cover plate. The box body is fixedly installed within the cabinet body cavity by screws, and the cover plate is snap-fitted to the box body, with the cover plate located at the front of the box body. Multiple sets of wire winding posts are provided within the box body cavity for layering and organizing cables, arranged symmetrically in a stepped manner. A wire clamping and layering unit is fixedly installed on the inner side wall of the box body cavity by screws, used to clamp cables and arrange them in layers. The wire clamping and layering unit includes a mounting base, an upper clamping plate, and a lower clamping plate.
[0009] According to the natural gas PLC cabinet, the winding post is fixedly installed on the inner side wall of the box cavity, and mounting holes are equally spaced at the middle position of the inner side wall of the box cavity.
[0010] According to the natural gas PLC cabinet, both the upper and lower clamping plates have protrusions at the ends near the mounting base, and the front end of the mounting base has a movable groove. The protrusions of the upper and lower clamping plates are movably engaged in the corresponding movable grooves.
[0011] According to the natural gas PLC cabinet, a first arc block is fixedly installed at the end of the upper clamping plate near the lower clamping plate, and a second arc block is fixedly installed at the end of the lower clamping plate near the upper clamping plate. The first arc block and the second arc block are staggered.
[0012] According to the natural gas PLC cabinet, a limit rod is fixedly installed at the end of the upper clamping plate away from the mounting base, and a cylindrical tube is fixedly installed at the end of the lower clamping plate away from the mounting base. The limit rod movably passes through the cylindrical tube and the lower clamping plate.
[0013] According to the natural gas PLC cabinet, a threaded hole is provided at the middle position of the front end of the mounting base, and the screw fixes the mounting base to the inner wall of the box through the threaded hole.
[0014] According to the natural gas PLC cabinet, guide rods are fixedly installed in the movable slots of the mounting base.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] Please see Figure 1-6 As shown, this utility model is a natural gas PLC cabinet, including a cabinet body 10. Multiple sets of wiring box assemblies for storing wire harnesses are installed inside the cabinet body 10 cavity. Each wiring box assembly includes a box body 11 and a cover plate 12. The box body 11 is fixedly installed inside the cabinet body 10 cavity by screws, and the cover plate 12 is snap-fitted to the box body 11, with the cover plate 12 located in front of the box body 11. Multiple sets of winding posts 14 are provided inside the box body 11 cavity for layering and sorting cables. These winding posts 14 are arranged symmetrically in a stepped manner. A wire clamping and layering unit 15 is fixedly installed on the inner side wall of the box body 11 cavity by screws, used to clamp cables and arrange them in layers. The wire clamping and layering unit 15 includes a mounting base 16, an upper clamping plate 17, and a lower clamping plate 18.
[0026] Specifically, by installing a wiring box assembly inside the cabinet 10 cavity, the cables connecting the components are stored inside the box 11 cavity, making the layout inside the cabinet 10 cavity look neat and convenient for later maintenance. However, due to the large number of cables, the cables are prone to tangling during maintenance and cable replacement, causing maintenance difficulties and increasing maintenance time and workload. This application fixes this problem by fixing multiple sets of wire-winding posts 14 inside the box 11 cavity. The multiple sets of wire-winding posts 14 are symmetrically distributed in a stepped shape. The cables are wound around the outer wall of the wire-winding posts 14 below the corresponding components, thereby achieving a neat and layered arrangement of messy cables, which is convenient for cable replacement and later installation. By setting a wire-clamping layering unit 15 on one side of the wire-winding post 14, the corresponding cables can be clamped, further arranging the cables in layers. On the other hand, the cables are limited to prevent the cable ends from falling off during installation and maintenance.
[0027] Among them, such as Figure 1-2 As shown, the winding post 14 is fixedly installed on the inner side wall of the cavity of the box 11, and mounting holes 13 are equally spaced at the middle position of the inner side wall of the cavity of the box 11.
[0028] Specifically, the wire winding post 14 is fixedly installed on the inner side wall of the box 11 cavity, and the excess wire is wound on the outer wall of the lower wire winding post 14. The box 11 is installed in the cabinet 10 cavity by setting the mounting holes 13 at equal intervals in the middle position of the inner side wall of the box 11 cavity.
[0029] Among them, such as Figure 3-4 As shown, both the upper clamping plate 17 and the lower clamping plate 18 have protrusions at their ends near the mounting base 16. The front end of the mounting base 16 has a movable groove, and the protrusions of the upper clamping plate 17 and the lower clamping plate 18 are movably engaged in the corresponding movable grooves. A first arc block 19 is fixedly installed at the end of the upper clamping plate 17 near the lower clamping plate 18, and a second arc block 21 is fixedly installed at the end of the lower clamping plate 18 near the upper clamping plate 17. The first arc block 19 and the second arc block 21 are staggered.
[0030] Specifically, by setting the front end of the mounting base 16 to have a movable groove, the protruding ends of the upper clamping plate 17 and the lower clamping plate 18 are movably engaged in the corresponding movable groove, which plays a role in limiting and guiding the movement of the upper clamping plate 17 and the lower clamping plate 18. By setting the end of the upper clamping plate 17 near the lower clamping plate 18 to be fixedly installed with a first arc block 19, and the end of the lower clamping plate 18 near the upper clamping plate 17 to be fixedly installed with a second arc block 21, the first arc block 19 and the second arc block 21 are staggered. The upper clamping plate 17 and the lower clamping plate 18 are close to each other, clamping the cable between the upper clamping plate 17 and the lower clamping plate 18. The first arc block 19 and the second arc block 21 have a larger contact area with the cable, resulting in a better clamping effect.
[0031] Among them, such as Figure 5-6As shown, a limiting rod 20 is fixedly installed at the end of the upper clamping plate 17 away from the mounting base 16, and a cylindrical tube 22 is fixedly installed at the end of the lower clamping plate 18 away from the mounting base 16. The limiting rod 20 movably passes through the cylindrical tube 22 and the lower clamping plate 18. A threaded hole 23 is provided at the middle position of the front end of the mounting base 16, and a screw is used to fix the mounting base 16 to the inner wall of the box 11 through the threaded hole 23. Guide rods 24 are fixedly installed in the movable grooves of the mounting base 16. The guide rods 24 movably pass through the protrusions at the corresponding ends of the upper clamping plate 17 and the lower clamping plate 18. Compression springs 25 are sleeved on the outer wall of the guide rods 24, and the two sets of compression springs 25 are respectively located at the ends of the guide rods 24 away from the upper clamping plate 17 and the lower clamping plate 18.
[0032] Specifically, a limiting rod 20 is fixedly installed at the end of the upper clamping plate 17 away from the mounting base 16, and a cylindrical tube 22 is fixedly installed at the end of the lower clamping plate 18 away from the mounting base 16. The limiting rod 20 moves through the cylindrical tube 22 and the lower clamping plate 18, allowing the upper clamping plate 17 and the lower clamping plate 18 to move vertically. The limiting rod 20 and the cylindrical tube 22 are engaged, further improving structural stability. A threaded hole 23 is opened at the middle position of the front end of the mounting base 16, and a screw is used to fix the mounting base 16 to the inner wall of the box body 11 through the threaded hole 23. A guide rod 24 moves through the protrusions at the corresponding ends of the upper clamping plate 17 and the lower clamping plate 18. A compression spring 25 is set to reset the upper clamping plate 17 and the lower clamping plate 18, bringing them closer together.
[0033] The specific working principle of this utility model of a natural gas PLC cabinet is as follows: A winding post 14 is fixedly installed on the inner side wall of the housing 11. Excess wires are wound around the outer wall of the winding post 14. Mounting holes 13 are evenly spaced at the middle of the inner side wall of the housing 11 to facilitate installation of the housing 11 into the cabinet 10. A movable groove is provided at the front end of the mounting base 16, and the protruding ends of the upper clamping plate 17 and the lower clamping plate 18 are movably engaged in the corresponding movable groove, limiting the movement of the upper clamping plate 17 and the lower clamping plate 18. The cable is clamped between the upper clamping plate 17 and the lower clamping plate 18 by means of a first arc block 19 fixedly installed at one end of the upper clamping plate 17 and a second arc block 21 fixedly installed at one end of the lower clamping plate 18. The first arc block 19 and the second arc block 21 are staggered. The upper clamping plate 17 and the lower clamping plate 18 are close to each other to clamp the cable. A guide rod 24 is provided to move through the protrusions at one end of the upper clamping plate 17 and the lower clamping plate 18. A compression spring 25 is provided to reset the upper clamping plate 17 and the lower clamping plate 18.
