Description

Technical Field

[0001] The present invention relates to the technical field of ONUs, in particular to an expandable ONU switching device with a cleaning mechanism. Background Art

[0002] In modern communication network architectures, optical network units (ONUs) play a crucial role. They are the core device that connects user terminals to the backbone network. ONUs are classified into active optical network units (AOUs) and passive optical network units (POUs). They are feature-rich and can provide multiple services, including data, IPTV, and voice, truly achieving "Triple-Play" applications. They are widely used in surveillance, residential areas, government and enterprise offices, factories, basic education, hotels, and healthcare, among other fields. However, existing ONU switching devices typically operate continuously for extended periods of time, and during this process, dust and impurities easily accumulate on the outside of the device. Over time, this dust and impurities can gradually penetrate the device, damaging key components such as the ONU motherboard. Dust accumulation can also lead to poor heat dissipation of electronic components on the motherboard, affecting normal equipment operation and reducing efficiency. Current manual cleaning methods have significant drawbacks, often requiring the entire outer casing to be removed. This process is cumbersome and inconvenient, consuming significant manpower and resources. Furthermore, with the rapid development of communications technology and the ever-increasing demand for network services from users, the scalability of existing ONU switching devices has become increasingly prominent.

The two groups of horizontal brush cylinders and vertical brush cylinders provided with the dust sweeping piece can clean the sides of the ONU switch body on a large scale to avoid dust accumulation that may cause poor heat dissipation of electronic components on the mainboard.

[0023] Working principle: When cleaning, the ONU switch body 1 is pushed into the cleaning box 2, and the heat dissipation position of the ONU switch body is pushed into the docking groove 2212 opened on the front baffle 2211. Then, the servo motor 2221 can be powered on to start the rear drive shaft 2222 inside the cleaning box 2 to rotate. The rotation of the rear drive shaft 2222 can drive the front drive shaft 2226 at the front end to rotate through the transmission belt 2225. The front drive shaft 2226 and the rear drive shaft 2222 rotate synchronously to drive the installed first fan 2223 and the second fan 2227 to rotate, so as to dissipate heat for the ONU switch body 1. When the front drive shaft 2226 rotates, the second belt group 235 can drive the bottom side screw rod 232 to rotate in the sleeves 231 on both sides. The rotation of the screw rod 232 can drive the wire drum 233 to move to the left. When the wire drum 233 moves, the fixed pushing block 234 can push the cleaning box 251 to move. The dust cleaning box 251 slides in the guide rail 21 through the sliders 253 fixed on both sides. When the dust cleaning box 251 slides, the two groups of dust sweeping parts 252 inside the dust sweeping parts 252 are in operation. The two groups of horizontal brush cylinders 2524 and the two groups of vertical brush cylinders 2526 in the dust sweeping parts 252 roll and clean the sides of the ONU switch body 1. When the two groups of horizontal brush cylinders 2524 and the two groups of vertical brush cylinders 2526 roll and clean the sides of the ONU switch body 1, the dust cleaned in the center can be mixed in the center of the dust cleaning box 251. As the cleaning member 25 moves, the rotation of the transmission belt 2225 can engage the fixed gear 2410 in the center to rotate. The rotation of the fixed gear 2410 can drive the rotating rod 249 to rotate. The rotation of the rotating rod 249 can drive the rotating shaft 246 inside the fixed box 244 to rotate through the sprocket set 248. The rotating shaft 246 rotates in the side blocks 245 on both sides. The rotation of the rotating shaft 246 can drive the third fan 247 fixed in the center to rotate. The rotation of the third fan 247 can blow air to the right. The blowing of the third fan 247 can be transported through the connecting hose 243 and the upper air pipe 242, and the dust floating in the cleaning box 251 is adsorbed and extracted through the connected square connecting box 241. When cleaning is completed, you only need to pull the ONU switch body 1 outward to a certain position without affecting the heat dissipation of the ONU switch body 1 itself. The operation ends here.
