[0035] Working principle of the invention: The working principle of this structure is based on the premise that the buoyancy of the rising water in the floating structure 3-1 is greater than the downward force of the downward spring 331-2, and at the same time the thrust of the closing spring clip 14-4 is greater than the damping force of the sealing rubber pad 14-7.

[0036] Under normal conditions, due to the pulling effect of the pull cord 3-4, the closed spring clip 14-4 is in a compressed state. At the same time, the pull cord 3-4 restricts the closed window panel 14-6 from rotating around the rotating shaft 14-1. The pull cord 3-4 is wound and fixed on the outside of the pull cord winding roller 33-2. When the pull cord winding roller 33-2 can rotate, the pull cord 3-4 can be released from the outside of the pull cord winding roller 33-2. The water level floating structure 3-1, the linkage rod structure 3-2, and the trigger structure 3-3 in the trigger structure remain at their lowest positions. At the same time, the pressing spring 331-2 is at its maximum pressing stroke. The toothed rod 331-1 at one end of the anti-rotation rod 33-1 engages with the inner side of the inner toothed ring 331-5.

[0037] When the water level rises, the buoyancy provided by the water pushes the foam float 31-1 upward. Simultaneously, the float support rod 31-2, balance linkage rod 32-1, fixing ring 32-2, upward push rod 32-3, and rod end push plate 32-4, all fixed to it, move upward, pushing the anti-rotation rod 33-1 to rotate around the connecting shaft protrusion 331-3. As it rotates, the toothed rod 331-1 at one end of the anti-rotation rod 33-1 gradually disengages from the meshing contact with the inner toothed ring 331-5. When the inner toothed ring 331-5 is no longer restricted in its rotation, the pull rope winding roller 33-2, which is integrated with it, begins to rotate. At the same time, the winding mechanism is set to... The pull rope 3-4 on the outside of roller 33-2 will be released from the outside of the pull rope wrapped around roller 33-2. The main function of pull rope 3-4 is to compress the sealing spring clip 14-4 and restrict the rotation of the sealing window plate 14-2. The height restriction of pull rope 3-4 is released downward. Under the action of sealing spring clip 14-4, the sealing window plate 14-2, window edge sealing plate 14-6, and edge sealing pad 14-7 rotate around the rotating shaft 14-1. Thus, the window edge sealing plate 14-6 and edge sealing pad 14-7 are inserted into the heat dissipation window 4, thereby sealing the heat dissipation window 4 and isolating the internal environment from the external environment.

[0038] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
