Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a people's air defense basement mobile power station ventilation system, including restraining dust bag 1, restraining dust bag 1 and just having the flexibility for tubular structure, restraining the vertical setting of dust bag 1. Be provided with ventilation pipe 2 on ventilation system's of basement air-out pipeline 5, ventilation pipe 2 and air-out pipeline 5 intercommunication, the upper end and the ventilation pipe 2 sealing connection of dust suppression bag 1, the lower extreme that presses down dust bag 1 can contact with ground. The user is through stopping the mobile power station at the dust suppression bag 1 lower extreme and start, will restrain 1 covers of dust bag and establish on the mobile power station, and the most harmful gas that can make the mobile power station during operation discharge seals in pressing down dust bag 1 and gets into the underground chamber of discharging in the air-out pipeline 5 through ventilation pipe 2, plays the function that reduces the underground chamber and discharge harmful gas by the mobile power station. It is provided with updraft ventilator 11 to restrain 1 upper end of dirt bag, and updraft ventilator 11 can take out the gas that is located updraft ventilator 11 below to updraft ventilator 11 top, through set up updraft ventilator 11 on pressing down dirt bag 1, makes updraft ventilator 11 can extract the gas that presses down in the dirt bag 1 and discharge to air-out pipeline 5 through ventilation pipe 2, plays the effect of accelerating the efficiency of airing exhaust.

Referring to fig. 1 and 2, a plurality of folding devices 3 for folding the dust suppression bag 1 are arranged on the dust suppression bag 1, and each folding device 3 comprises a sliding roller 31, two sliders one 32 and a power device 34 for driving the sliders one 32 to move. Two opposite sides of the dust suppression bag 1 are respectively provided with a mounting plate 35, and the mounting plate 35 is arranged on the basement wall 6. The mounting plate 35 is disposed below the ventilation pipe 2. The folding devices 3 are sequentially arranged on the mounting plate 35 at intervals in the vertical direction. The sliding roller 31 is horizontally arranged, two ends of the sliding roller 31 are respectively connected with a first sliding block 32, the mounting plate 35 is provided with a plurality of first sliding grooves 33, and the first sliding blocks 32 are slidably connected in the first sliding grooves 33. The length direction of the first sliding chute 33 is the horizontal direction, and the first sliding block 32 can slide along the length direction of the first sliding chute 33, so that the first sliding chute 33 can drive the sliding roller 31 to slide back and forth along the horizontal direction. The power device 34 is arranged on the first slide block 32, and a user can control the power device 34 to enable the power device 34 to drive the first slide block 32 and the slide roller 31 to slide. When restraining dust bag 1 and being in the natural state of drooping, all sliding roller 31 all are in restraining dust bag 1 outside, and two adjacent sliding roller 31 homogeneous phases are relative to restraining dust bag 1 not unilateral setting this moment in the vertical direction. When the mobile power station is used and the dust suppression bag 1 needs to be folded, a user can horizontally move the first sliding block 32 and the sliding rollers 31 by starting the power device 34, and at the moment, all the sliding rollers 31 move towards the direction close to the dust suppression bag 1 and are in contact with the dust suppression bag 1. The sliding rollers 31 continue to move, so that the dust suppression bag 1 deforms due to the jacking of the sliding rollers 31, and along with the increase of the moving distance of the sliding rollers 31, the dust suppression bag 1 can be folded into a folding shape by the sliding rollers 31, so that the lower bottom end of the dust suppression bag 1 moves towards the direction far away from the ground, the effect of retracting the dust suppression bag 1 is achieved, and the mobile power station is convenient for users to transport.
