[0039] The water vapor of the impermeable roof slope layer can be guided and discharged through the inside of the stainless steel pipe 1 and the gap between the two stainless steel pipes 1. After the installation of the front end mounting frame 4, the tail end mounting frame 5 and the plurality of stainless steel pipes 1 is completed, the rotating motor 13 can be started to drive the plurality of rotating shafts 9 to rotate by the transmission of the central synchronous gear 14, the synchronous track 15 and the plurality of lateral synchronous gears 11, so that the plurality of exhaust impellers 10 on the rotating shafts 9 can rotate synchronously and quickly.

[0048] S4, stainless steel pipe 1 is fixedly laid on the roof slope layer.

[0049] The working principle of the present invention is as follows:

[0050] 1. When in use, the water vapor of the anti-seepage roof slope layer can be guided and discharged through the inside of the stainless steel pipe 1 and the gap between the two stainless steel pipes 1. After the installation of the head end mounting frame 4, the tail end mounting frame 5 and the several stainless steel pipes 1 is completed, the rotary motor 13 can be controlled to start, and the transmission effect of the central synchronous gear 14, the synchronous crawler 15 and the several lateral synchronous gears 11 can be used to drive the several rotating shafts 9 to rotate, so that the exhaust impellers 10 on the several rotating shafts 9 can rotate synchronously and rapidly.

When the screw thread 21 is tightened and the screw thread 22 is tightened, the screw thread 22 is tightened, and the screw thread 22 is tightened. When the screw thread 21 is tightened and the screw thread 22 is tightened, the screw thread 22 is tightened, and the screw thread 22 is tightened.

[0052] 3. When the negative pressure exhaust device for the anti-seepage roof slope layer is disassembled for maintenance, that is, during the disassembly operation of the head end mounting frame 4, the tail end mounting frame 5 and the plurality of stainless steel pipes 1, the bidirectional lead screw 26 can be driven to rotate by rotating the disassembly knob 30, so that the two guide blocks 27 can move toward each other, and at the same time, the transmission action of the transmission rod 28 is used to drive the lifting top plate 29 to move upward, so as to simultaneously push the plurality of disassembly paddles 24 upward, so that the plurality of plug-in shafts 19 can synchronously release the locking limit of the plurality of arc-shaped fixing plates 21, thereby realizing the synchronous disassembly operation of the plurality of stainless steel pipes 1, which is beneficial to improving the convenience of disassembly and use and the efficiency of maintenance operation of the negative pressure exhaust device for the anti-seepage roof slope layer.
