Example two:
the present embodiment provides a flexible telescopic open anti-cold leakage device, which is different from the first embodiment in that:
in the embodiment shown in fig. 7 to 8, the horizontal roller blinds are respectively connected to the guide plates, the roller fans 6 are respectively installed on the two oppositely arranged guide plates, and the roller fans 6 blow air towards the opening area in an opposite direction to form opposite air flows.
Wherein, two deflectors are fixed respectively on the second curtain pole of two horizontal roll curtain subassemblies, when second curtain pole was pulled, the wheel of deflector lower extreme rolled in horizontal track, a plurality of cylinder fans of close row installation on the deflector, the cylinder fan on both sides is blowing about, the air current that blows out from the tangential air outlet, the cylinder fan axial for producing the air curtain is longer, the air outlet is narrower, the air current that blows out forms one air curtain, with keep apart inside and outside cold and hot space, further prevent air conditioning and reveal.
Example three:
the present embodiment provides a flexible telescopic open anti-cold leakage device, which is different from the second embodiment in that:
in the embodiment shown in fig. 9, the guide plate is provided with a boss, a photoelectric switch 61 is mounted on the boss, and the photoelectric switch 61 is arranged at two ends of the drum fan. In order to further save energy and ensure that only the fan positioned in the opening is started and the fan positioned outside the opening is not started, a photoelectric switch is arranged at the two ends of each roller fan on the guide plate and faces one side of the vertical roller shutter. The transmitting end and the receiving end of the photoelectric switch are integrated in the same module, and whether the photoelectric switch is shielded or not is sensed by detecting reflected light. Because the horizontal roller shutter assembly is far away from the vertical roller shutter assembly, the photoelectric switch is directly mounted on the guide plate and cannot be detected, and a boss is arranged at the mounting position of the guide plate, so that the photoelectric switch is close to one side of the vertical roller shutter assembly.
When one of the photoelectric switches at the two ends of a certain roller fan is shielded, the roller fan is started; when both the photoelectric switches are shielded, the drum fan is turned off. The air blowing device can ensure that air is blown only at the interface of the opening area, and air is not blown in the closed area. The top and the bottom do not need to install photoelectric switches, and the roller fans at the two positions only need to be controlled by one photoelectric switch.
Other specific structures and implementation processes can be referred to in the first embodiment.
Example four:
the present embodiment provides a flexible telescopic open anti-cold leakage device, which is different from the first embodiment in that:
in this embodiment perpendicular roll up curtain subassembly need not to set up first putting the curtain motor and first receipts curtain motor, and perpendicular roll up curtain subassembly need not to set up the second and puts curtain motor and second receipts curtain motor, uses torsional spring connection between first rolling axle and the railway carriage or compartment body respectively, and is corresponding, also uses torsional spring connection between second rolling axle and the railway carriage or compartment body respectively. Meanwhile, the guide plate is provided with a groove, when the horizontal roller shutter is released, the groove on the guide plate is directly pulled by hands, and the horizontal roller shutter is released; when the curtain is collected, the direction plate is pushed back, and the horizontal roller shutter is rolled up by the second rolling shaft under the action of the pretightening force of the torsion spring.

Because the horizontal roller shutter is arranged at the outer side of the vertical roller shutter, the vertical roller shutter can be pulled open only by pulling open the horizontal roller shutter. When the curtain is closed, the vertical roller shutters need to be folded first, and then the horizontal roller shutters need to be folded.
In this embodiment, the pretightning force of torsional spring is no longer than the frictional force between horizontal track and the deflector all the time, and the deflector can stop in any position on the horizontal track, can push and pull the deflector according to actual demand. Likewise, the pre-tension of the torsion spring does not exceed the friction between the vertical guide rail and the first curtain rod.
As shown in fig. 10, the flexible retractable anti-cold-leakage device of this embodiment can be applied to a refrigerator car with a vertically arranged door, and can also be applied to an incubator 7 with a horizontally arranged door, and the incubator has a small size and does not need to be provided with a drum fan.
