Example 1

[0024] Please see Figures 1-6 This utility model discloses a modular integrated control cabinet, including a cabinet body 1 and a cabinet door 2 connected to the cabinet body 1, and also including a power module assembly 3, a control module assembly 4, a signal module assembly 5, a module expansion assembly 6, an isolation assembly 7, and a cable tray assembly 8, wherein:

[0025] The cabinet 1 includes a support frame 11. The outer layer of the support frame 11 is fixed with a galvanized steel plate 12 and an aluminum alloy steel plate 13 by bolts. Specifically, the outer aluminum alloy steel plate 13 has the characteristics of being lightweight and high-strength, and the inner galvanized steel plate 12 has electromagnetic shielding performance.

[0026] Please refer to the appendix. Figure 3 The isolation assembly 7 includes an isolation cover 71, which is fixed to the isolation base plate 72 by screws. The isolation base plate 72 is fitted into the support frame 11 and slides in fit. The isolation cover 71 has a cable inlet hole 711 on one side and a cable clamp 73 on the other side. Specifically, the detachable isolation base plate 72 is easy to install, maintain and expand.

[0027] Please refer to the appendix. Figure 5The cable tray assembly 8 includes a cable tray base plate 81. The inner walls of the cabinet 1 are welded to both ends of the cable tray base plate 81. A cable tray cover 82 is fixed to the top of the cable tray base plate 81 by screws. Three sets of symmetrically arranged cable clips 83 are provided on the cable tray base plate 81. The two sides of the cable clips 83 are connected to the cable tray base plate 81 by springs 84. Specifically, by pulling the cable clips 83 to both sides and compressing the springs 84, the cables are placed between the cable clips 83. By releasing the cable clips 83, the cables can be classified and fixed in a standardized manner.

[0028] The cable tray cover 82 has three inlet holes 821 at one end, and the cable tray base plate 81 has three outlet holes 811 arranged at equal intervals. The inlet hole 711 is fitted with a sealing ring 74, and the isolation base plate 72 has an outlet hole 75.

[0029] In this embodiment, high-voltage cables, low-voltage cables, and control cables can be inserted into the three inlet holes 821 of the cable tray cover 82 and exited through the outlet holes 811. The cable clips 83 on the cable tray base plate 81 are used to limit the different cables, realize classified binding, standardize cable management, and greatly improve the efficiency of subsequent cable fault diagnosis. Example 2

[0030] Based on the above embodiment 1, please refer to the appendix. Figure 2 , Figure 4 as well as Figure 6 The cable clamp 73 includes a clamp 731 arranged symmetrically on the upper and lower sides. The clamp 731 is welded to a torsion spring 732. The torsion spring 732 is nested on the outside of the connecting post 733. The connecting post 733 is welded with an isolation cover 71.

[0031] The cable clamp 83 is provided with several clamping slots 831. The three sets of cable clamps 83 and the three cable outlet holes 811 are arranged correspondingly and set on the same horizontal line. Specifically, the three sets of cable clamps 83 cooperate with the cable outlet holes 811 on their respective horizontal lines to avoid cable crossing and confusion, and facilitate later maintenance.

[0032] Cabinet door 2 is connected to cabinet body 1 via hinge 21. Cabinet door 2 is provided with several louvers 22, and several start buttons 23 are provided between the louvers 22. Specifically, the louvers 22 can improve heat dissipation inside and facilitate observation of abnormal conditions inside the cabinet.

[0033] The power module assembly 3 includes a switching power supply 31 and a UPS power supply 32. Both the switching power supply 31 and the UPS power supply 32 are fixed to the isolation base plate 72 with screws. The control module assembly 4 includes a PLC controller 41 and several relays 42. Specifically, the relays 42 adopt integrated relay modules to reduce the number of wiring and improve reliability.

[0034] The PLC controller 41 has a latch 43 at its bottom, which connects to the guide rail 44. The guide rail 44 is fixed to the isolation base plate 72 by screws. The signal module assembly 5 includes an isolator 51 and a transmitter 52. The module expansion assembly 6 includes several expansion slots 61. Specifically, pulling the latch 43 can detach the PLC controller 41 from the guide rail 44, which can facilitate the adjustment of the position of the PLC controller 41 to adapt to the installation of different models of PLCs. Various functional expansion modules can be inserted into the expansion slots 61 as needed.

[0035] In this embodiment, when fixing the cable extending from the isolation cover 71 and the isolation base plate 72, pressing one end of the clamp 731 causes the clamp 731 to rotate around the connecting column 733 and drive the torsion spring 732 to stretch and store elastic potential energy, thereby allowing the cable to be placed between the clamps 731. When one end of the clamp 731 is released, the torsion spring 732 rebounds, thus achieving the limitation and stable support of the cable.

[0036] The working principle and usage process of this utility model are as follows: When installing cables, high-voltage cables, low-voltage cables and control cables are respectively inserted into the three inlet holes 821 of the cable tray cover 82 and exited from the outlet holes 811. The cable clips 83 on the cable tray base plate 81 are used to limit the different cables, realize classified binding, standardize cable management, and greatly improve the efficiency of subsequent cable fault diagnosis.

[0037] The cable extending from the outlet hole 811 passes through the inlet hole 75 on one side of the isolation cover 71 and is electrically connected to the electrical components inside the isolation cover 71 for power and data exchange. Then, the cable extending from the internal electrical components passes through the outlet hole 75 on the isolation base plate 72 and is re-classified and bound through the cable tray assembly 8 below. The cable clamp 73 can centrally fix the incoming and outgoing cables, and together with the sealing ring 74, ensures the stability and sealing of the cables.

[0038] The power module component 3 outputs a stable DC voltage to power other modules. The signal module component processes the collected field signals and transmits them to the control module component 4 via cable. The control module component 4 analyzes and processes the signals according to a preset program, and outputs control signals to the signal module. The signal module then drives the actuator to control the field equipment.
