the surface of the display screen 13 is strongly impacted due to the large external wind force, and the strong air flow which is in contact with the surface of the display screen 13 flows along the curved surface and flows out through the ventilation groove 143 on the fixing frame 14 because the surface of the display screen 13 is a curved surface, so that the impact on the surface of the display screen 13 is reduced; because the display body 11 is rotatably connected with the mounting rod 141, and the mounting rod 141 is eccentrically arranged, when strong wind impacts the surface of the display screen 13, the pressure applied to the parts of the surface of the display screen 13 positioned at the two sides of the mounting rod 141 is different, so that the display body 11 rotates around the mounting rod 141, the elastic rope 142 connected to the display body 11 is deformed in a tensile manner, and the impact applied to the display body 11 is relieved along with the rotation of the display body 11; after the display machine body 11 rotates, the side wall of the display machine body 11 is separated from the side wall of the fixed frame 14, and the gap between the side wall of the display machine body 11 and the side wall of the fixed frame 14 is increased, so that strong airflow flowing along the curved surface of the display screen 13 further flows out through the gap between the side wall of the display machine body 11 and the side wall of the fixed frame 14, the impact on the surface of the display screen 13 is reduced, the damage caused by overlarge impact on the display screen 13 is avoided, the phenomenon that the whole indicator 1 is overturned due to the overlarge impact on the surface of the display machine body 11 is also avoided, and the guiding effect of the indicator 1 on refuge people is influenced;

therefore, by arranging the water tank 22 on the fixing seat 2, when the fixing seat 2 needs to be fixed, water is injected into the water tank 22 through the water inlet pipe 222, and when the injected water is filled in the water tank 22, the weight of the water tank 22 is increased, so that the weight of the fixing seat 2 is increased, the stability of the sign 1 is enhanced, the sign 1 is further prevented from being overturned under the action of strong wind, and the sign 1 can normally play a role; when the sign 1 needs to be transferred, the water outlet pipe 223 is opened, so that water in the water tank 22 flows out rapidly, the weight of the fixed seat 2 is reduced greatly, and the working strength of carrying the sign 1 by rescuers is reduced; when the surface of the display screen 13 of the indicating plate 1 is subjected to strong impact under the blowing action of strong wind, the indicating plate 1 is pressed to drive the fixing rod 15 to swing, so that the end part of the fixing rod 15 positioned in the water tank 22 drives the first plate 151 to swing and extrude the water in the water tank 22, and meanwhile, the spring connected with the first plate 151 is pressed to deform, at the moment, the kinetic energy generated by the indicating plate 1 under the impact action of the strong wind is converted into the elastic potential energy of the spring connected with the first plate 151 and the kinetic energy and the internal energy of the water in the water tank 22, so that the impact action on the indicating plate 1 is relieved, and the indicating plate 1 is prevented from being damaged due to overlarge impact action; when the wind power is reduced, because the first plate 151 is made of EVA (ethylene vinyl acetate), the first plate 151 is low in density and is subjected to high buoyancy in water, and the first plate 151 is subjected to the deformation recovery effect of the connected springs, so that the first plate 151 quickly drives the fixing rod 15 to reset, and the indication board 1 is enabled to reset smoothly; the situation of water supply and power failure in a disaster area can occur, water is difficult to be supplemented into the water tank 22 in time, time is urgent under the disaster relief situation, rescue workers need to put into disaster relief work quickly after installing the ground nails 213, and rainwater or river water is not collected to fill the water tank 22; therefore, in the case of emergency, after the rescue workers determine that the rainwater is large and can continue for a period of time, the water receiver 23 is mounted on the water inlet pipe 222, and then the rescue workers can be quickly put into disaster relief work; at this time, the falling rainwater flows into the water inlet pipe 222 along the water receiver 23 and flows into the water tank 22 after contacting with the inner surface of the end part with the larger section of the water receiver 23, the interior of the water tank 22 is quickly filled with the rainwater in continuous rainwater weather, and the interior of the water tank 22 is automatically filled through the action of the water receiver 23, so that the time and the energy of rescue workers are saved; the end part of the water inlet pipe 222 is flush with the inner surface of the side wall of the water tank 22, so that the condition that the indicator 1 collides with the end part of the water inlet pipe 222 when the indicator 1 is pressed to drive the first plate 151 to rotate is avoided; the larger end part of the section of the water receiver 23 is positioned above the box cover 221, and according to the principle of a communicating device, the water receiver 23 can continuously inject rainwater into the water tank 22 until the water tank 22 is full of rainwater; excessive water in the water tank 22 can flow out through the first groove 224, so that excessive water pressure in the water tank 22 is avoided; when the sign 1 is impacted by stronger wind force to drive the first plate 151 to swing, the water pressure inside the water tank 22 is increased due to pressure, so that part of water inside the water tank 22 flows into the second groove 145 through the first pipe 147, the second plate 146 in the second groove 145 is pressed to move, and the elastic rope 142 connected with the second plate 146 further moves towards the direction close to the display body 11; therefore, when the display body 11 swings under the impact of strong wind, the elastic rope 142 is pulled to extend out of the elastic rubber block 144 for increasing the swing range of the display body 11, and the gap between the side wall of the display body 11 and the side wall of the fixed frame 14 is further increased, so that the airflow impacting the display screen 13 further flows out from the gap between the side wall of the display body 11 and the side wall of the fixed frame 14, and the impact on the display body 11 is reduced; when the wind power is reduced, the water pressure in the water tank 22 is recovered, the water in the second groove 145 returns to the inside of the water tank 22 through the first pipe 147 under the extrusion of the second reset plate 146, and the elastic rope 142 is quickly reset under the driving of the second plate 146, so that the sidewall of the connected display machine body 11 is further ensured to swing under the pulling force and overcome the obstruction of the elastic rubber block 144 to be successfully reset.
