From the passenger's perspective, the average stay time for entering or exiting the station is less than 3 minutes, and the presence or absence of heating equipment has no significant impact. However, it is difficult for security personnel who are on duty in public areas for a long time to maintain a comfortable working environment.

[0003] According to the measured data of an open-air elevated station in Tianjin, the average temperature of the working area of ​​the security personnel at the station during the day is -1.2℃.

The reflector device is fixed to the bottom of the protruding beam plate through a reflector device connecting component, and the quartz tube heating element 2 is fixed to the bottom of the protruding beam plate through a heating device connecting component.

[0032] The heating device connection assembly comprises a first strip hole formed in the protruding beam plate, a metal telescopic rod 7 is arranged in the first strip hole, and the lower end of the metal telescopic rod 7 is connected to the quartz tube heating element 2.

[0035] The first strip holes and the second strip holes are arranged in parallel in the extended beam plate.

[0036] A knob connector 8 is provided at the upper end of the metal telescopic rod 7 , and the metal telescopic rod 7 is fixed by the knob connector 8 .

[0037] The reflector device comprises a PVC shell 6, a heat preservation layer 5 is arranged inside the PVC shell 6, and a high-brightness lattice reflector 4 for reflection is arranged inside the heat preservation layer 5.

[0038] The high-brightness lattice reflector 4 is an arc-shaped panel that reflects the heat radiation of the quartz tube heating element 2 .

[0039] Specifically, the integral bracket 1 also includes a fixing portion fixed to the existing security door, and a diagonal bracing rib is provided between the fixing portion and the extended beam plate, so as to ensure the cantilever strength of the extended beam plate.

[0040] Specifically, the protruding beams in the integral support 1 are two parallel beams.

[0041] Specifically, the insulation layer 5 is a composite magnesium silicate insulation material, and the insulation layer 5 is bonded together with the PVC shell 6 and the high-gloss surface lattice reflector 4 by fire-resistant glue to form a radiation reflector device.

[0042] Specifically, the metal telescopic rod 7 is a vertical telescopic rod, and the position of the metal telescopic rod 7 and the position of the PVC shell 6 can be adjusted in the length direction.

[0043] Specifically, the first strip hole and the second strip hole in the extended beam plate provide adjustment space for the lateral adjustment of the metal telescopic rod 7 .

[0044] Specifically, the knob connector 8 is a clamping nut with a star-shaped fixed knob. When the nut rotates forward, the nut and the knob clamp the cantilever section of the overall bracket 1 to achieve a fixed suspension effect; conversely, when the nut rotates reversely, the nut and the knob loosen, allowing the metal telescopic rod 7 and its connecting parts to move horizontally in the strip hole.

[0050] More specifically, a wireless controller 9 is also provided at the groove wall of the groove plate, and the wireless controller 9 is used for on-off control of the power supply of the quartz tube heating element 2, and for receiving and sending signals.

[0051] Specifically, in the present invention, the first strip hole, the second strip hole, and the metal telescopic bracket 7 are used to realize the relative movement of the reflector device, the quartz tube heating element 2, and the anti-mistouch device 3, thereby adjusting the radiation angle and the heating area.

[0052] More specifically, the positions of the reflector device, the quartz tube heating element 2, and the anti-mistaken touch device 3 can be flexibly distributed through the first strip hole and the second strip hole, and the positions can be flexibly exchanged. Thus, it is possible to adjust which side of the existing security door is heated to meet the heating needs of the area outside the security door.

[0053] Specifically, the integral bracket 1 is made of a high-strength, high-modulus, and light-weight material, and is responsible for bearing the weight and connecting various components, serving as a main body installation support structure.

[0054] Specifically, the quartz tube heating element 2 has a stepless power adjustment function and is linked with the wireless control module 9 to realize user control.
