In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.

Example one

Referring to fig. 1-3, a self-protection warning type safety barrier for plateau areas comprises a barrier body 1, two warning plates 2 are embedded in the side wall of the barrier body 1, a semi-hollow cylinder 3 matched with the two warning plates 2 is fixedly connected to the side wall of the barrier body 1, a strip-shaped cavity 4 is formed in the barrier body 1, two arc-shaped cavities 5 are symmetrically formed in the side wall of the semi-hollow cylinder 3, permanent magnets 7 are hermetically and slidably connected to the inner walls of the two arc-shaped cavities 5, the inner wall of the strip-shaped cavity 4 is fixedly connected with the inner walls of the two arc-shaped cavities 5 through a connecting pipe 6, it is noted that through holes are formed in the inner walls of the arc-shaped cavities 5 away from the connecting pipe 6, be used for balancing the pressure intensity change in the arc chamber 5 when permanent-magnet 7 slides, frame mouth 11 has been seted up at the top in the bar chamber 4, and frame mouth 11 inner wall fixedly connected with convex lens 12, install on half hollow cylinder 3 and carry out the attraction mechanism that attracts mutually permanent-magnet 7 under the high temperature.

The attraction mechanism is including inlaying the permanent magnetism post 8 of establishing at half hollow cylinder 3 inner walls, and permanent magnetism post 8 is repulsive with permanent magnetism 7, and 8 lateral walls covers of permanent magnetism post are equipped with excitation coil 9, and the bottom inlays in bar chamber 4 and is equipped with thermoelectric generation board 10, and thermoelectric generation board 10 is connected with excitation coil 9 coupling.

Be equipped with nitrogen dioxide and nitrogen tetroxide gas mixture in bar chamber 4, further, can take place reversible reaction between nitrogen dioxide and the nitrogen tetroxide, the reaction formula is: n is a radical of₂O₄＝2NO₂(reversible), the nitrogen dioxide is reddish brown, the dinitrogen tetroxide is colorless, and when the temperature in the mixed gas rises, the reaction equilibrium of the mixed gas proceeds towards the generation of the nitrogen dioxide, the content of the nitrogen dioxide in the mixed gas increases, and the color of the mixed gas becomes dark.

It should be noted that the repulsive force between the permanent magnet post 8 and the permanent magnet 7 is much larger than the pressure of the mixed gas in the bar-shaped cavity 4 to the permanent magnet 7.

The magnetic field direction of the excitation coil 9 is opposite to that of the permanent magnet column 8, and the magnetic field of the excitation coil 9 is far larger than that of the permanent magnet column 8, so that after the excitation coil 9 is electrified, the magnetic field direction of the permanent magnet column 8 can be changed, and the permanent magnet blocks 7 can be attracted.
