Heat insulation device for indoor tall and large space area

The invention discloses an indoor tall and large space area heat insulation device which comprises a rectangular frame formed by connecting cross beams and longitudinal beams, supporting devices are arranged below the four corners of the rectangular frame, and a plurality of light-transmitting heat insulation plates are arranged below the two cross beams at intervals in the direction parallel to the length direction of the cross beams. Supporting rods extending in the vertical direction are arranged at the two ends of the light-transmitting heat insulation plate respectively, sliding seats are fixedly connected to the upper ends of the supporting rods, the supporting rods are slidably connected to the cross beams on the sides where the supporting rods are located through the sliding seats, every two adjacent sliding seats are connected together through a traction rope, and sliding seat driving devices used for driving the sliding seats to slide are installed on the cross beams. The lower end of the supporting
