Detailed Description

The present invention will be further described with reference to the following examples.

The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple modifications of the method of the present invention based on the concept of the present invention are within the scope of the claimed invention.

Referring to fig. 1-3, the present invention provides a submarine tunnel safety protection device, which includes an outer shell 10, a cavity is formed in the outer shell 10, an inner shell 30 is installed in the outer shell 10, the bottom end of the inner shell extends to the cavity, a filling seat 20 is installed on the lower surface of the inner wall of the outer shell 10, a second film 102 is installed in the cavity, a first solution is filled between the cavity below the second film 102 and the filling seat 20, a first film 305 is installed in the inner shell 30, a second solution capable of generating gas in cooperation with the first solution is filled in the inner shell 30 above the first film 305, a puncturing assembly for puncturing the first film 305 and the second film 102 to mix the first solution and the second solution is installed in the inner shell 30, the puncturing assembly includes a floating ball 302, a first thimble 301 and a second thimble 303, the first thimble 301 and the thimble 303 are respectively installed on the upper surface and the lower surface of the floating ball 302, the thimble 303 passes through a through hole, a limiting component for limiting the first thimble 301 is arranged in the inner shell 30; the first thimble 301 and the second thimble 303 move up and down by utilizing the characteristic that the floating ball 302 moves up and down when vibrated, so that the first thimble 301 and the second thimble 303 can respectively pierce the first film 305 and the second film 102, and the first solution and the second solution can be mixed.

The limiting assembly comprises a limiting ring 306, and the first thimble 301 penetrates through the upper part of the limiting ring 306; the first thimble 301 can be limited by the limiting ring 306, so that the stability of the first thimble 301 during up-and-down movement can be guaranteed.

A spring 307 is arranged on the outer surface of the first thimble 301, and two ends of the spring 307 are respectively fixedly connected with the lower surface of the limiting ring 306 and the upper surface of the floating ball 302; by arranging the spring 307, the reverse acting force generated when the spring 307 is deformed by force acts on the floating ball 302, so that the floating ball 302 is driven to drive the second thimble 303 to move downwards to puncture the second film 102.

An air outlet 101 communicated with the cavity is formed in the left side surface of the shell 10, and an air bag 40 communicated with the air outlet 101 is installed at a position, opposite to the air outlet 101, on the left side surface of the shell 10.
