通风与空调系统中风管系统清洗设备的设计

Design of cleaning equipment of air duct system in heating ventilation and air-conditioning system

利用运动小车上的滚刷扬尘,用吸尘器把灰尘吸出来,是目前国内外风管清洗设备最主要的形式。针对"在有较重积尘的情况下,积尘很难通过长长的风管进入吸尘器"的问题,设计了一种吸尘头,该吸尘头靠抬臂机构预压紧,调整吸尘头与风管之间的距离,并在此基础上设计了一个吸尘头自压紧风管底部的机构,这样机器人在运动时可适应风管不同位置上底部的不平整。即使风管稍有不平或接缝之处,也可以吸尽粉尘。研究结果表明,共用运动平台减轻了维护工作量,降低了清洗设备的制造成本;利用吸尘管形成负压方式,不需在整个风管内形成负压,可以大大降低吸尘电机的功率。

The dust raising by brush on the small car and vacuumed is the mainly of cleaning technology of vent duct at home and abroad.Aiming that the heavier dust is not easily through the long duct,a vacuum head was designed.Through the lifting or dropping the lifting ap-pliance,it could adjust the distance between the air duct and the vacuum head,at the same time there is a self-pressed devices in the vacu-um head to suit for the uneven bottom surface of the different location of the duct.Even if the duct is slightly uneven or has seams,the dust can be exhausted.The results indicate that using the same platform can reduce the maintenance workload and manufacturing costs of cleaning equipment.Using the local negative pressure which provided by vacuum tube,the power of motor can be greatly reduced.
