In order to realize the installation of the rotating shaft 702, the upper end of the water tank 6 is provided with a front mounting plate 701 and a rear mounting plate 701, the rotating shaft 702 penetrates through the mounting plates 701, and the rotating shaft 702 can rotate around the mounting plates 701; the one-way gear 703 is composed of an outer ring gear and an internal one-way clutch; the inner ring of the one-way clutch is connected with the rotating shaft 702 through a flat key; the clockwise rotation of the one-way gear 703 can drive the rotating shaft 702 to rotate together.

In order to provide sufficient oxygen and facilitate breathing, a breathing bag 14 is arranged on the hose 12, and the box body 8 is filled with oxygen-enriched gas; the float valve 10 is in a manually closed state.

In order to limit the lowest position of the flat plate 3, a limit nut 15 is fixed on each support rod 2.

In order to realize the water inlet and outlet of the water tank 6, the bottom of the water tank 6 is provided with a water inlet hole 16 and an overflow hole 17, and the diameter of the overflow hole 17 is smaller than that of the water inlet hole 16; the water inlet hole 16 is provided with a one-way water inlet valve.

In order to prevent the hoses 12 from scattering, a baffle 18 is arranged at the front side of the placing groove 11.

First, the function of the case 8 of the present invention will be explained: the box body 8 provides buoyancy for lifting the flat plate 3 when encountering flood; on the other hand, air or oxygen-enriched air inside the box 8 can be used for breathing in case of emergency. The shape of the box 8 should conform to the arc of the tunnel and be as large as possible in size. If the cost of the gas in the box body 8 is limited, the gas can be directly used as air, and the air is kept fresh through the air exchange pipes 9 on the two sides of the box body 8; if the oxygen-enriched gas is used under the condition that the condition allows, emergency rescue can be better provided.

Under the conventional state, namely under the condition that no water flows into the tunnel, the flat plate 3 is at the lowest position, the lowest position is limited by the limiting nut 15, the stability of the flat plate 3 is kept, the daily maintenance operation is convenient, and a conventional refuge and escape platform is provided; meanwhile, along with the operation of the subway, the air in the tunnel flows, so that the air in the box body 8 can be slowly ventilated through the ventilation pipe 9.

When encountering a flood, the water flow rushes into the tunnel and gradually raises the water level in the tunnel, see fig. 5; at the moment, firstly, the float valves 10 on the air exchange pipes 9 at two sides of the box body 8 are closed, so that water does not enter the box body 8, and an air storage chamber is formed; if oxygen-enriched gas is used, the float valve 10 is in a manually closed state and is not affected thereby. Then the box body 8 will rise under the action of buoyancy, and drive the flat plate 3, the sleeve 4, the water tank 6 and the like to rise together.

In the initial state, that is, when there is no water in the water tank 6, the vertical rod 706 does not block the shift lever 704 on the rotating shaft 702; the one-way gear 703 is freely rotatable, i.e., the plate 3 is freely raised or lowered. When water is met, the water can enter the water tank 6; meanwhile, the one-way gear 703 can rotate counterclockwise along with the rising of the flat plate 3; because a part of the water tank 6 is below the water level, the floating block 705 in the water tank 6 receives the action of buoyancy, the vertical rod 706 on the floating block 705 moves upwards and blocks the shifting rod 704, and after the shifting rod 704 is blocked, the one-way gear 703 can only rotate anticlockwise, so that the rising of the whole flat plate 3 is not influenced. At this time, once an external force is applied to the flat plate 3, the lowering of the flat plate 3 causes the one-way gear 703 to rotate clockwise, but the rotating shaft 702 cannot rotate along the pointer, so that the flat plate 3 cannot be lowered, and the bearing of the flat plate 3 is realized.

Because the flat plate 3 is positioned above the water surface under the action of the box body 8, people in distress can break away from the water surface after climbing the flat plate 3, thereby preventing temperature loss and being capable of escaping along the flat plate 3 quickly.

Meanwhile, if breathing is difficult, the hose 12 can be pulled out, the mask 13 is buckled on the face, and the breathing bag 14 is pressed, so that oxygen-enriched gas or fresh air in the box body 8 can be absorbed, emergency breathing assistance is provided, and the waiting rescue time is prolonged.

In conclusion, if water flows backward into the subway, the flat plate 3 can automatically rise and keep above the water surface, so that the flat plate 3 is clearly visible, and people can leave the water surface to quickly escape; after a person stands on the flat plate 3, the flat plate 3 can be automatically locked and does not descend. Because a plurality of dull and stereotyped 3 are independent each other, remaining dull and stereotyped 3 still can reciprocate along with the water level, and the dull and stereotyped 3 in the front is higher than the surface of water all the time when guaranteeing to flee from.

When the water level is lowered, the water level in the water tank 6 is lowered slowly because the overflow holes 17 of the water tank 6 are smaller, namely, the water in the water tank 6 is lowered after the water level in the tunnel is lowered to a certain degree; after the water in the water tank 6 descends, the floating block 705 descends, and the vertical rod 706 above the floating block 705 descends and is not blocked by the deflector rod 704; at this time, the rotating shaft 702 and the one-way gear 703 can rotate along the pointer, see fig. 4; the flat plate 3 will automatically reset downwards under the action of self-weight. The water flow in the water tank 6 is slowly reduced, so that the effect of delaying reduction is provided, and the water tank is more reliable and stable. And simultaneously, the influence of water surface fluctuation on the state of the flat plate 3 can be prevented.

When the water has completely dissipated, eventually, the entire device will return to its original state.

In conclusion, the plate 3 of the device can automatically rise without descending when water exists. When no water exists, the device automatically descends, is simple and reliable, is convenient to maintain, can provide simple breathing assistance, and prolongs the waiting rescue time.
