when the curtain wall plate fixing device works, the connecting strength between the inner curtain wall plate 1 and the outer curtain wall plate 2 is improved through the connecting plate 3, and carbon dioxide gas is intermittently introduced into and extracted from the fixing rod 43 in hot summer, so that the adjusting rod 44 makes telescopic motion in the fixing rod 43; when the adjusting rod 44 extends towards the direction close to the rubber block 46, the adjusting rod 44 drives the hinge rod 45 to move, and further drives the partition board 4 to move towards the direction close to the inner curtain wall board 1, so that hot air between the inner curtain wall board 1 and the partition board 4 is extruded and discharged from the first air outlet 48; when the adjusting rod 44 contracts, the adjusting rod 44 drives the hinge rod 45 to move, the hinge rod 45 drives the partition plate 4 to move towards the direction close to the outer curtain wall plate 2, so that the volume of the space between the outer curtain wall plate 2 and the partition plate 4 is reduced, the compressed hot air is discharged through the second air outlet 33, meanwhile, the space between the inner curtain wall plate 1 and the partition plate 4 is increased, the air pressure is reduced, and cold air is absorbed from the outside through the air inlet 31; the curtain wall system moves repeatedly, air inlet and air exhaust efficiency is accelerated through sliding of the partition plates 4, air flow between the inner curtain wall plate 1 and the outer curtain wall plate 2 is improved, and therefore the heat dissipation effect of the curtain wall system is effectively improved; meanwhile, the air inlet 31 absorbs air from the outside, and the air enters a smaller space from a larger space at the air inlet 31, so that the air is gathered and concentrated, the flow rate of the air entering between the inner curtain wall plate 1 and the partition plate 4 is improved, and the heat exchange effect is enhanced; moreover, because the air inlet 31 is designed in a funnel shape, air is difficult to enter the end with the larger space from the end with the smaller space, thereby playing a role in preventing backflow; similarly, by configuring the first outlet 48 and the second outlet 33 as funnel-shaped, the discharge rate of the hot air can be increased and the hot air can be prevented from flowing backward;
meanwhile, when the adjusting rod 44 extends towards the direction close to the rubber block 46, the adjusting rod 44 extrudes the rubber block 46 to enable moisture on the absorbent cotton 47 in the rubber block 46 to be extruded and sprayed out, the moisture is sprayed on the partition plate 4 and the inner curtain wall plate 1 to cool the partition plate 4 and the inner curtain wall plate 1, the water is a phase-change material, the moisture sprayed out of the micropores is less, the moisture sprayed on the partition plate 4 and the inner curtain wall plate 1 is quickly absorbed and evaporated, and the cooling effect is further improved; meanwhile, an air conditioner drainage system or a water storage system is used for providing water for the water absorption cotton 47, so that the resource utilization rate can be improved, the energy consumption and the operation cost are reduced, and the economic benefit is improved; in winter, the air inlet duct 32 and the second air outlet 33 are closed to enable air between the inner curtain wall board 1 and the outer curtain wall board 2 to circularly flow to generate a greenhouse effect, so that the heat preservation performance of the curtain wall system is improved, and meanwhile, the partition board 4 is arranged to provide a certain blocking effect for the curtain wall system, so that heat loss is further prevented; in addition, by arranging the smoke sensor and the first control valve 5, when the smoke sensor senses fire smoke, the first control valve 5 is opened to enable carbon dioxide in the air source and the fixing rod 43 to enter between the partition plate 4 and the inner curtain wall plate 1, and the carbon dioxide gas isolates air to play a role in fire prevention and extinguishment, so that the fire spread is prevented, and the safety of a curtain wall system is improved;
meanwhile, when the acting force applied to the outer curtain wall board 2 is large, the outer curtain wall board 2 drives the connecting board 3 to move towards the direction close to the inner curtain wall board 1, one end of the connecting rod extrudes the air bag 12 to enable the air in the air bag 12 to enter the cavity 14 in the supporting board 13, so that the supporting board 13 is driven to expand and arch to be in contact with the outer curtain wall board 2, the supporting board 13 can support the outer curtain wall board 2 due to the fact that the arch structure has certain pressure bearing capacity, the outer curtain wall board 2 is prevented from being sunken and deformed in severe weather such as strong wind, hail and the like, the wind deformation resistance of the outer curtain wall board 2 is enhanced, and the service life of the outer curtain wall board 2 is prolonged; when the acting force on the outer curtain wall board 2 is too large, the connecting plate 3 continuously extrudes the air bag 12 to enable the supporting plate 13 to be in contact with the outer curtain wall board 2, part of air enters the telescopic rod 17, an extension rod of the telescopic rod 17 extends out to drive the partition plate 4 to move towards the direction close to the outer curtain wall board 2, and the acting force on the outer curtain wall board 2 is converted into elastic potential energy of the supporting plate 13 and the elastic piece, so that the supporting effect on the outer curtain wall board 2 is further improved; meanwhile, the rubber pad 18 plays a role in buffering and protecting when the support plate 13 is in contact with the outer curtain wall plate 2, and the outer curtain wall plate 2 is prevented from being directly in contact with the support plate 13 to be damaged by friction, so that the service life of the outer curtain wall plate 2 is prolonged; meanwhile, the water cavity 49 absorbs heat and vaporizes when the temperature is higher, and solidifies and releases heat when the temperature is lower, so that the heat insulation and adjustment performance of the curtain wall system is further improved; the water cavity 49 can improve the fire resistance of the curtain wall system and prevent the fire from spreading when a fire disaster happens, so that the safety performance of the curtain wall system is improved; meanwhile, the water cavity 49 is designed to be S-shaped, so that the quantity of filled water can be reduced, the quality of the partition plate 4 is reduced, the partition plate 4 can slide conveniently, and the normal operation of the device is ensured.
