DETAILED DESCRIPTION

[0021] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments or drawings are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] A wooden heat-insulating fireproof door, such as Figure 1 As shown, it includes a door frame 1 and a door panel 2, the door panel 2 is hingedly installed in the door frame 1, a handle 3 is installed on the door panel 2, the door panel 2 is composed of an external wooden shell 4 and an internal support frame 5, a first partition 6 and a second partition 7 distributed front and back are installed in the support frame 5 respectively, two partition plates 8 are arranged on the first partition 6, the partition plates 8 divide the space between the first partition 6 and the second partition 7 into three insulation chambers, the left and right insulation chambers are filled with liquid insulation material and are installed with a spiral shaft 10, the middle insulation chamber is filled with liquid water, a third partition 31 located in front of the first partition 6 is installed in the support frame 5, and the space between the third partition 31 and the first partition 6 is filled with solid insulation material;

[0023] A bracket 11 is installed on the top of the support frame 5. The top ends of the first partition 6, the second partition 7 and the third partition 31 are all against the bottom end of the bracket 11. A through hole 12 connected to the middle insulation cavity is provided at the bottom of the bracket 11. A steam transmission mechanism 13 is installed in the bracket 11. The upper end of the screw shaft 10 extends into the bracket 11 and is dynamically connected to the steam transmission mechanism 13.

[0024] In the early stages of a fire, some fire doors are far away from the burning area and mainly serve to block smoke. The smoke has heat and is distributed in the upper half of the passage. Therefore, the upper part of the fire door is in direct contact with the smoke, and the temperature rises rapidly. A temperature difference occurs between the upper and lower areas of the fire door. If the temperature difference is large, the door panel 1 will be deformed. In this case, due to the high temperature, the liquid water in the middle insulation cavity will vaporize to produce high-pressure steam. With the cooperation of the steam transmission mechanism 13, the spiral shafts 10 in the left and right insulation cavities are driven to stir the liquid insulation material upward, thereby reducing the temperature difference between the upper and lower areas of the door panel 1, and thereby slowing down the heating rate of the upper area of ​​the door panel 1.

[0025] like Figure 1 As shown, the steam transmission mechanism 13 includes a wind wheel 20 installed in the bracket 11 and located above the through hole 12, and a cover body 21 covered on the outside of the wind wheel 20. The wind wheel 20 is installed in the bracket 11 in a rotatable manner. The wind wheel 20 is connected to a driving shaft 22, and the upper end of the driving shaft 22 extends to the outside of the cover body 21 and is installed with a driving bevel gear 23. A transmission shaft 24 is rotatably connected in the bracket 11, and the transmission shaft 24 is installed with a first bevel gear 25 meshing with the driving bevel gear 23. A driven bevel gear 26 is installed on the upper end of the spiral shaft 10, and second bevel gears 27 meshing with adjacent driven bevel gears 26 are installed at both ends of the transmission shaft 24.

[0026] The high-pressure steam generated by the vaporization of liquid water in the middle heat-insulating cavity drives the wind wheel 20 to rotate, and drives the spiral shaft 10 to rotate under the transmission of the bevel gear set, thereby achieving the function of stirring the liquid heat-insulating material.

[0027] like Figure 1As shown, a through pipe 28 is installed on the support frame 5, and the lower end of the through pipe 28 is connected to the cover body 21. A groove 29 and a cover plate 30 installed in the groove 29 are provided at the top of the wooden shell 4. The upper end of the through pipe 28 extends into the groove 29 at the top of the wooden shell 4 and is located at the lower side of the cover plate 30. The cover plate 30 is installed in the groove 29 in a rotating connection manner. Under normal circumstances, the cover plate 30 closes the upper end opening of the through pipe 28 to prevent the liquid water in the middle insulation cavity from being lost due to natural evaporation. It can also be replenished by pouring liquid water into the through pipe 28. If high-pressure steam is discharged from the upper end of the through pipe 28, it can push the cover plate 30 to flip upward, so that the upper end opening of the through pipe 28 is in an open state, so that the high-pressure steam can be discharged from the door panel 2. In addition, the groove 29 is located at the upper end surface of the top of the wooden shell 4, which is relatively hidden and does not affect the appearance of the door panel 2.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
