Abstract

The invention discloses a movable cable tunnel ventilator which comprises a fan, a protecting screen and a screen cover. The movable cable tunnel ventilator is characterized in that the fan comprises an air duct and a fan fixing frame, the air duct is of a flaring type, a noise reducing board is arranged on the inner side of the air duct, the fan fixing frame is fixed on an upper flaring of the air duct, the protecting screen is fixed at the lower end of the air duct, a shock pad is fixed between the fixing frame and the screen cover, and two symmetrically arranged handles provided with antiskid pads are arranged on the screen cover. The movable cable tunnel ventilator integrated with the screen cover, the protecting screen and the fan can be directly placed on a cable wellhead to perform ventilation operation on the interior of the cable wellhead. The movable cable tunnel ventilator is simple in structure and highly practical.

Description

technical field [0001] The invention relates to a ventilator, in particular to a movable cable tunnel ventilator. Background technique [0002] As we all know, due to the long-term humid environment in the cable tunnel, a large amount of harmful gas has accumulated. When the cable needs to be repaired, it must go through a ventilation operation before it can be lowered into the well to ensure the safety of workers. At present, the commonly used cable tunnel ventilation systems are fixed in special ventilation shafts with ventilation fans to perform ventilation operations in the cable shafts. Due to the long-term humid environment, the ventilation system is easily rusted or damaged, resulting in failure to work normally. Therefore be necessary to provide a kind of movable, easy-to-operate ventilator, ventilate and take a breath to the cable tunnel at any time. Contents of the invention [0003] According to the technical problem raised above, a movable cable tunnel ventil...
