[0026] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0027] like Figure 1-5 As shown, an online monitoring PLC control cabinet according to an embodiment of the present invention includes a cabinet body 1 and a dustproof box 2. The dustproof box 2 is fixedly installed on the upper surface of the cabinet body 1. The dustproof box 2 enables air intake and dust prevention to prevent dust from affecting the operation of components. The dustproof box 2 is provided with a snap-fit ​​assembly 3. The snap-fit ​​assembly 3 includes multiple first telescopic rods 301 installed inside the dustproof box 2. Each first telescopic rod 301 has a first spring 302 sleeved on its outer wall. The spring elasticity is used to make the snap-fit ​​block 303 and the snap-fit ​​groove 304 tightly snap-fit ​​together, and at the same time facilitate the disassembly of the dustproof plate 305. The telescopic ends of the multiple first telescopic rods 301 are fixedly connected to the snap-fit ​​block 303. The dustproof box 2 has a snap-fit ​​groove 304. The snap-fit ​​block 303 and the snap-fit ​​groove 304 are snap-fitted together with the dustproof plate 305.

[0028] The cabinet 1 is equipped with a heat dissipation component 4 to cool the interior of the cabinet 1 and ensure the normal operation of electrical components. The heat dissipation component 4 includes a support frame 401 fixedly installed inside the cabinet 1, which provides installation support for two motors 402 and ensures the stable operation of the motors 402. Two motors 402 are installed inside the support frame 401. The output end of each motor 402 passes through the support frame 401 and is connected to multiple fan blades 403. The heat dissipation component 4 is located below the dustproof box 2. The dustproof box 2 has an air inlet 11, which works with the dustproof plate 305 to achieve clean air intake. The outer wall of the cabinet 1 has two sets of heat dissipation vents 12 to exhaust the hot air inside the cabinet and form a complete heat dissipation air duct.

[0029] The cabinet 1 has two sets of fixing blocks 5 and two baffles 9 fixedly installed inside. Each set of fixing blocks 5 has a second telescopic rod 6 fixedly installed on its outer wall. Each set of second telescopic rods 6 has a second spring 7 sleeved on its outer wall, which pushes the pressure plate 8 toward the baffle 9 to ensure that the wire harness is clamped and fixed, and at the same time facilitates the removal and placement of the wire harness. Each set of second telescopic rods 6 has two pressure plates 8 fixedly installed at its telescopic end. The baffle 9 is adapted to the pressure plate 8 to achieve the clamping and fixing of the wire harness. Each pressure plate 8 has a through groove 10 on its outer wall.

[0030] The cabinet 1 has two sets of slots 13 inside, which are adapted to bolts 15 to provide a channel for adjusting the installation position of the back plate 14. The cabinet 1 has multiple back plates 14 inside, and each back plate 14 has two bolts 15 threaded inside. The bolts 15 are adapted to the slots 13. The cabinet 1 is equipped with a temperature monitoring module 16, which adopts the Omron CP1W-TS003 model, to monitor the temperature inside the cabinet in real time and provide signal support for temperature control. It is suitable for the industrial use of PLC control cabinets and can realize multi-point temperature acquisition and stable signal transmission. The cabinet 1 has two cable inlets 17 inside. The bottom of the cabinet 1 is equipped with four support legs 20. The front of the cabinet 1 is hinged with a cabinet door 18. The front of the cabinet door 18 is equipped with an observation window 19 and a controller 21. The observation window 19 allows the staff to observe the operating status of the components inside the cabinet in real time.

[0031] The working principle of this invention is as follows:

[0032] During operation, external air first enters through the air inlet 11 of the dustproof box 2, and is filtered by the dustproof plate 305 to achieve dust prevention. When cleaning or replacing the dustproof plate 305, the first telescopic rod 301 and the first spring 302 in the snap-fit ​​assembly 3 drive the snap-fit ​​block 303 to extend or retract, so that the snap-fit ​​block 303 is disengaged from or engaged with the snap-fit ​​slot 304 of the dustproof box 2, thereby quickly completing disassembly and maintenance. The filtered clean air flows downward, passes through the heat dissipation assembly 4, and is driven by the output end of the motor 402 to rotate the fan blade 403 to form a directional airflow. After passing through the component area, the airflow is discharged through the heat dissipation vent 12 of the cabinet 1. The wiring harness is installed inside the cabinet. Between the pressure plate 8 and the baffle 9, the fixing block 5 of the cabinet 1 supports the second telescopic rod 6. The second spring 7 on its outer wall pushes the pressure plate 8 and the baffle 9 to press and fix the wire harness. The back plate 14 is used to install electrical components. It is connected to the slot 13 of the cabinet 1 by bolts 15 and can be adjusted in installation position. The internal temperature monitoring module 16 transmits the temperature signal to the controller 21 of the cabinet door 18, which controls the start, stop and speed of the motor 402 to achieve intelligent temperature control. The cable is introduced through the inlet 17. The support leg 20 supports the cabinet 1 and prevents moisture. The staff can observe the operating status through the observation window 19. The whole system achieves stable integrated operation.
