[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Example 1, referring to Figures 1-4 An operating cabinet includes: an operating cabinet body 1 (material: stainless steel 304; thickness 1.5mm), an installation opening on the top of the operating cabinet body 1, and a cooling fan 2 (air volume ≥200CFM; noise ≤35dB) fixedly installed in the installation opening. When the cooling fan 2 is activated, it can draw air from the operating cabinet body 1 to dissipate heat inside the operating cabinet body 1. Air inlet mechanisms 4 are provided on both sides of the operating cabinet body 1.
[0025] The air intake mechanism 4 includes an air duct 5 (material: aluminum alloy 6063; wall thickness 2mm). The air duct 5 slides through one side of the control cabinet body 1 (the contact surface is equipped with a silicone sealing ring, hardness 50±5Shore A). One end of the air duct 5 is fixedly connected to a back plate 6 (material: galvanized steel plate). A limit frame 10 (material: ABS engineering plastic) is fixedly connected to the circumference of the air duct 5. Multiple air inlets 8 (hole diameter φ5mm; spacing 10mm) are opened around the air duct 5. The air inlets 8 are located between the back plate 6 and the limit frame 10. Moving the air duct 5 can change the position of the air inlets 8, thereby preventing dust falling from the filter 16 when replacing the filter 16 from being sucked into the control cabinet body 1, and improving the cleanliness of the control cabinet body 1 when replacing the filter 16.
[0026] A positioning frame 14 (material: stainless steel 304) is fixedly connected between the inner walls of both sides of the air duct 5. A filter screen 16 (material: activated carbon composite filter material; filtration efficiency ≥95% PM2.5; thickness 10mm) is provided on one side of the positioning frame 14. The filter screen 16 is used to filter dust and impurities in the air.
[0027] This application can be used in the field of electrical equipment control cabinets, or in other fields applicable to this application.
[0028] Example 2, Reference Figures 1-4 Based on Example 1, an improved PLC-based electrical equipment automation control cabinet is proposed and applied to the field of electrical equipment control cabinets.
[0029] In this utility model, a guide frame 13 (material: ABS engineering plastic) is fixedly connected to the end of the air duct 5 away from the back plate 6. A limiting frame 17 for limiting the filter screen 16 is inserted into the guide frame 13. The limiting frame 17 is used to limit the filter screen 16.
[0030] In particular, two anti-disassembly plates 9 are fixedly connected to one side of the outer wall of the control cabinet body 1. One of the anti-disassembly plates 9 is located on one side of the limit frame 17 and is used to limit the limit frame 17. The anti-disassembly plate 9 blocks the limit frame 17 to prevent the filter screen 16 from being replaced before the air duct 5 is pulled out, thus avoiding improper operation.
[0031] It should be noted that two symmetrically arranged insert plates 7 (material: galvanized steel plate) are fixedly connected to one side of the back plate 6. Each insert plate 7 has two slots 12 on its surface. The two insert plates 7 pass through the two anti-dismantling plates 9 respectively. Each side of the two anti-dismantling plates 9 has a through slide 21. T-shaped locking blocks 19 are slidably connected in the slide 21. Springs 20 are fixedly connected between the locking blocks 19 and the slide 21. An n-shaped handle 18 is fixedly connected between the two locking blocks 19. The handle 18 slides through the top of the two anti-dismantling plates 9. The locking blocks 19 are used to fix the air duct 5. Pulling the handle 18 will cause the crossbar 19 to move upward, thereby allowing the air duct 5 to be pulled out.
[0032] In this utility model, a top cover 3 is fixedly connected to the top of the control cabinet body 1, and the cooling fan 2 is located inside the top cover 3. The top cover 3 serves to protect the cooling fan 2.
[0033] In particular, a pull plate 15 is fixedly connected to one side of the guide frame 13, which facilitates the pulling out of the air duct 5.
[0034] However, as is well known to those skilled in the art, the working principles and wiring methods of the control cabinet body 1 and the cooling fan 2 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
