Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Please refer to the attached Figure 1 -Attached Figure 4 A building exterior wall panel maintenance device includes a maintenance bin 1, one side of the maintenance bin 1 is connected to a bin door via a hinge, a PLC controller is fixed to the top surface of the maintenance bin 1, a maintenance component is arranged inside the maintenance bin 1, and the maintenance component includes two support plates 2 fixed inside the maintenance bin 1, a screw rod 201 is rotatably connected between the two support plates 2, an outer wall of the screw rod 201 is threadedly connected to a movable bar 202, a plurality of air ducts 203 are arranged on the front side of the movable bar 202, the air duct 203 is an L-shaped structure, a heating pipe 204 and a cross-flow fan 205 are respectively arranged inside the air duct 203, a plurality of exhaust pipes 206 are inserted on the front side of the movable bar 202, and a plurality of exhaust holes are opened on the bottom surface of the exhaust pipe 206.

[0022] In the embodiment, a first motor is fixed to one side of the support plate 2 close to the right side of the curing bin 1, and the output shaft of the first motor passes through one side of the support plate 2 and is fixed to one end of the screw rod 201, a driving shaft of the cross flow fan 205 is rotatably connected to the front side of the movable bar 202 and extends to the rear side of the movable bar 202, a first gear is fixed to the driving shaft end of the cross flow fan 205, a second motor is fixed to the top surface of the movable bar 202, a second gear is fixed to the output shaft of the second motor, several first gears are meshed with the second gear through a toothed belt, one end of the heating tube 204 is fixed to the front side of the movable bar 202, a fog maker 207 is fixed to the top surface of the curing bin 1, a delivery pipe 208 is connected to the mist outlet of the fog maker 207, the delivery pipe 208 passes through and extends to the interior of the curing bin 1, several of them pass through the front side of the movable bar 202 and are connected and fixed to the outer wall of the delivery pipe 208, and several placement racks 209 are arranged inside the curing bin 1, and the placement racks 209 Fixed to the front side of the support plate 2, several placement racks 209 are respectively located below several air ducts 203. By placing the exterior wall panels that need to be cured inside the curing bin 1 and then blowing the hot air flow onto the exterior wall panels through the cross-flow fan 205 and the heating tube 204, the drying of the concrete of the exterior wall panels is accelerated. At the same time, a fog maker 207 is used to transport water vapor to the exterior wall panels through the delivery pipe 208 and the exhaust pipe 206 to prevent the concrete of the exterior wall panels from lacking sufficient adhesion and causing flaky or powdery shedding on the surface. The air duct 203 is driven to move above the exterior wall panels by the laterally movable movable strip 202, thereby driving the air duct 203 and the exhaust pipe 206 to move laterally on the exterior wall panels, so that the hot air flow and water vapor can be evenly blown on the surface of the exterior wall panels, thereby increasing the curing effect on the exterior wall panels. The PLC controller is electrically connected to the first motor, the second motor, the heating tube 204, the fog maker 207 and the temperature and humidity sensor 4, respectively.

[0023] In the embodiment, ventilation holes 3 are opened on both sides of the curing bin 1, and an air filter 301 is fixed inside the ventilation hole 3. The air filter 301 can prevent external dust from entering the curing bin 1 during curing, thereby increasing the curing effect on the exterior wall panels.

[0024] In the embodiment, a temperature and humidity sensor 4 is fixed inside the curing chamber 1. Through the setting and use of the temperature and humidity sensor 4, the temperature and humidity conditions inside the curing chamber 1 can be monitored in real time, and the power of the heating tube 204 and the cross-flow fan 205 can be adjusted to ensure the best curing effect.

[0025] In the embodiment, a limiting rod 5 is fixed between the two support plates 2, and the movable bar 202 is slidably arranged with the outer wall of the limiting rod 5. Through the setting and use of the limiting rod 5, a limiting effect can be played on the movable bar 202, making the movable bar 202 more stable during movement.

[0026] In an embodiment, the exhaust pipe 206 is located directly below the bottom opening of the air duct 203. By arranging the exhaust pipe 206 to be located directly below the bottom opening of the air duct 203, when the cross-flow fan 205 blows, the water vapor discharged from the exhaust pipe 206 can be driven to quickly rush to the surface of the exterior wall panel, thereby increasing the maintenance effect.

[0027] Working principle: when in use, the exterior wall panels that need to be cured are placed on the placement rack 209. It is worth noting that the exterior wall panels have just been processed and the concrete on them has not dried yet. Therefore, the exterior wall panels are actually placed on the placement rack 209 together with the mold. The bottom surface of the exterior wall panels does not need to be cured inside the mold. Then the door of the curing chamber 1 is closed, and the first motor is started again to drive the screw rod 201 to rotate. Under the action of the movable bar 202 being connected to the outer wall thread of the screw rod 201, the movable bar 202 drives the air duct 203, the heating pipe 204 and the cross-flow fan 205 to move horizontally above the exterior wall panel. At this time, the second motor is started, and under the action of the meshing of several first gears with the second gear through the toothed belt, the second motor drives all the cross-flow fans 205 to rotate, thereby blowing air to the surface of the exterior wall panel. In this process, the heating pipe 204 and the fog maker 207 are started, and the heating pipe 204 and the cross-flow fan 20 5 is used to heat the air flow blown out, so that the air flow blowing toward the surface of the exterior wall panel is hot air, and the fog maker 207 generates water vapor and transports the water vapor to the exterior wall panel through the delivery pipe 208 and the exhaust pipe 206, so as to maintain the exterior wall panel. The air filter 301 can prevent external dust from entering the interior of the maintenance chamber 1 during maintenance, which can increase the maintenance effect of the exterior wall panel. Through the setting and use of the temperature and humidity sensor 4, the temperature and humidity conditions inside the maintenance chamber 1 can be monitored in real time, and the power of the heating pipe 204 and the cross-flow fan 205 can be adjusted to ensure the best maintenance effect. Through the setting and use of the limit rod 5, the movable bar 202 can be limited, so that the movable bar 202 is more stable during movement. By setting the exhaust pipe 206 directly below the bottom opening of the air duct 203, when the cross-flow fan 205 blows, the water vapor discharged from the exhaust pipe 206 can be driven to quickly rush to the surface of the exterior wall panel, thereby increasing the maintenance effect.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
