In this way, when the spring 222 is stretched and the plate body 21 is moved, the water discharge pipe 3214 and the air suction branch pipe 232 can be stretched normally and water flows normally, without damaging the water discharge pipe 3214 and the air suction branch pipe 232.

As shown in fig. 3 and 4, a spraying assembly 4 is further disposed on the plate body 21, the spraying assembly 4 includes a submersible pump 41, a spraying pipe 42 and an atomizing nozzle 43, the submersible pump 41 is installed in the water receiving tank 211, one end of the spraying pipe 42 is communicated with an outlet end of the submersible pump 41, the other end of the spraying pipe 42 passes through a tank wall of the water receiving tank 211 and then vertically extends downwards, the atomizing nozzle 43 is installed at one end of the spraying pipe 42 far away from the submersible pump 41, and the atomizing nozzle 43 faces towards an inner bottom wall side of the tunnel 1; the submersible pump 41 is also electrically connected with the controller 312, and the spraying amount of the atomizing nozzle 43 is smaller than the water filling amount of the water receiving tank 211. In this embodiment, one end of the spraying pipe 42 far away from the submersible pump 41 is communicated with a plurality of water spraying branch pipes, the plurality of water spraying branch pipes are uniformly distributed on the plate body 21 close to the plate surface on the inner bottom wall side of the tunnel 1, and the atomizing nozzles 43 are arranged on each water spraying branch pipe along the length direction of the water spraying branch pipes, so that the spraying range during spraying can be increased after the arrangement.

When the smoke sensor 311 senses dense smoke, the smoke sensor 311 transmits a dense smoke signal to the controller 312, the controller 312 directly controls the submersible pump 41 to start after receiving dense smoke information, water in the water receiving tank 211 is directly pumped into the spray pipe 42 and then is sprayed out from the atomizing nozzle 43, and the water is sprayed out in a form of fog water, so that the diffusion of the dense smoke in the tunnel 1 can be temporarily relieved; and the vehicle sometimes also has the naked light when taking place dense smoke, and the water smoke that sprays out can prevent the naked light to spread fast more effectively. Because the spraying amount of the atomizing spray head 43 is less than the water filling amount of the water receiving tank 211, the weight of the plate body 21 can be continuously increased in a spraying state, so that the plate body can normally move downwards; after water in the water storage tank 3212 all lets in the water receiving tank 211, only the atomizer 43 sprays water this moment, constantly emits the water in the water receiving tank 211, and the weight of the plate body 21 is lightening gradually at this moment, so the plate body 21 can be pulled back by the spring 222 vertically upwards gradually under the elastic force of the spring 222, thereby achieving the effect of automatically moving the plate body 21 vertically upwards.

As shown in fig. 2 and 4, a rainwater pipe 5 is also installed on the water storage tank 3212, a water through hole 12 penetrating the road surface is further formed in the top wall of the tunnel 1, the rainwater pipe 5 is placed in the water through hole 12, and one end of the rainwater pipe 5 close to the inside of the tunnel 1 is communicated with the water storage tank 3212; the road surface of tunnel 1 upper end is sunken to be set up, and the mouth of pipe of downspout 5 is located the sunken least significant end in road surface of tunnel 1 upper end. It should be noted that the road surface depression referred to in this application is not a conventional deep depression, but a groove with a slight slope, and the vehicle may feel a slight bump when running on the road surface, so that the vehicle can run slowly.

In rainy days, rainwater drops on the road surface above the tunnel 1, and the rainwater is collected in the depression of the road surface and then directly flows into the rainwater pipe 5; then flows into the water storage tank 3212, thereby achieving the effect of conveniently replenishing water in the water storage tank 3212 in rainy days.

As shown in fig. 2 and 5, an impurity filtering member 6 is disposed at an end of the rain pipe 5 far from the water storage tank 3212, the impurity filtering member 6 includes a cage-shaped filter net 61 and activated carbon 62, the cage-shaped filter net 61 is installed in the rain pipe 5, and the activated carbon 62 is placed in the cage-shaped filter net 61. Cage type filter screen 61 can dismantle the setting in downspout 5, installs in downspout 5 through ordinary bolted connection promptly, after impurity particle is piled up in the surperficial mesh of cage type filter screen 61, can tear down the clearance with cage type filter screen 61 to the inside active carbon 62 of cage type filter screen 61 also can be changed.

When rainwater flows on the road surface of the tunnel 1, particle impurities on the road surface are likely to be brought in, the cage-shaped filter screen 61 can partially block the impurity particles on the road surface, and then the activated carbon 62 in the cage-shaped filter screen 61 can purify the rainwater to a certain extent, so that the rainwater flowing into the water storage tank 3212 is relatively clean; thereby reach the partial particle impurity of filtration rainwater and purify the rainwater comparatively convenient effect.

The implementation principle of the main line frame structure under the road in the embodiment of the application is as follows: when a vehicle runs into the tunnel 1 and a traffic accident occurs to generate a large amount of dense smoke, the induction driving device 3 closest to the dense smoke can induce the dense smoke emitted by the running vehicle, and at the moment, the induction driving device 3 can drive the adsorption device 2 to vertically and downwardly approach, so that the emitted dense smoke is timely adsorbed, and the dense smoke is prevented from being diffused in the tunnel 1 to a certain extent; and the spraying piece can spray the open fire which can be generated in time, so that the open fire is prevented from further spreading.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
