Description

Technical Field

[0001] The utility model relates to a maintenance device for building concrete exterior walls, in particular to a maintenance device for building concrete exterior walls, belonging to the technical field of concrete exterior wall maintenance. Background Technique

[0002] In construction projects, to ensure the quality and service life of concrete exterior walls, a maintenance device is used to sprinkle water on the concrete exterior walls. By sprinkling water, the concrete exterior walls can be kept under suitable humidity and temperature conditions, thereby promoting the hydration reaction of cement, ensuring the hardening and strength of the concrete, and the sprinkling maintenance can effectively delay the shrinkage speed of the concrete, reduce the accumulation of internal stress, and thus significantly reduce the generation of cracks.

[0003] A concrete maintenance device for building construction disclosed in the Chinese Patent Application Publication Specification CN220848868U atomizes water and sprays it onto the concrete surface, enabling fine water mist particles to better penetrate the concrete surface and providing a more uniform coverage, thereby improving the maintenance effect and reducing the concrete temperature, which helps prevent premature temperature differences in the concrete and slows down the impact of temperature changes on the concrete.

[0004] However, during the implementation of the technical solution of the above patent, the sprinkling range cannot be adjusted according to the width of the concrete exterior wall. When the existing maintenance device sprinkles water on the concrete exterior wall, the sprinkler nozzles on the maintenance device are usually fixed, resulting in a fixed and relatively small sprinkling range. Therefore, the position of the maintenance device needs to be moved multiple times to ensure that the entire exterior wall is sprinkled with water, and this frequent movement of the device is rather cumbersome. Content of the Utility Model

[0005] The purpose of the utility model is to provide a maintenance device for building concrete exterior walls to solve the above problems, enabling the sprinkling range of the maintenance device to be adjusted according to the width of the concrete exterior wall.

[0006] The utility model is realized through the following technical solutions: A maintenance device for building concrete exterior walls includes a water storage tank, and a spraying mechanism is arranged above the water storage tank. The spraying mechanism includes an air cylinder, a fan is installed on the inner wall of the air cylinder, an annular hollow pipe is fixedly connected to the outer surface of the air cylinder, and a plurality of atomizing nozzles are fixedly connected to the inner wall of the annular hollow pipe;

[0007] An adjustment mechanism is provided above the water storage tank. The adjustment mechanism includes an adjustment frame and a fixed frame fixedly connected to the upper surface of the water storage tank. A threaded rod is rotatably connected to the inner wall of the fixed frame. An internally threaded slider is threadedly connected to the outer surface of the threaded rod. The internally threaded slider is slidably connected to the inner wall of the fixed frame. A first rotating rod is rotatably connected to the upper surface of the internally threaded slider. A connecting plate is fixedly connected to the top end of the first rotating rod. A second rotating rod is rotatably connected to the upper surface of the connecting plate;

[0008] A anti - detachment slider is fixedly connected to the top end of the second rotating rod. The anti - detachment slider is slidably connected to the inner wall of the adjustment frame. A U - shaped frame is fixedly connected to the upper surface of the adjustment frame. Two rotating shafts are rotatably connected to the inner wall of the U - shaped frame. One end of each of the two rotating shafts close to the air duct is fixedly connected to the outer surface of the air duct.

[0009] Preferably, the spraying mechanism further includes a water pump fixedly connected to the outer surface of the water storage tank. The input end of the water pump is fixedly connected to the outer surface of the water storage tank. The output end of the water pump is fixedly connected to a connecting hose. One end of the connecting hose away from the water pump is fixedly connected to the outer surface of the annular hollow pipe. By operating the water pump, the water in the water storage tank is pumped out and conveyed to the annular hollow pipe through the connecting hose.

[0010] Preferably, a rotating column is fixedly connected to the bottom surface of the adjustment frame. The bottom end of the rotating column is rotatably connected to the upper surface of the water storage tank. The rotating column plays a supporting role for the rotation of the adjustment frame.

[0011] Furthermore, a motor is fixedly connected to the upper surface of the internally threaded slider. A driving gear is fixedly connected to the output shaft end of the motor. A driven gear is fixedly connected to the outer surface of the first rotating rod. The driving gear meshes with the driven gear.

[0012] Specifically, an electric push rod is hinged to the upper surface of the adjustment frame. The top end of the electric push rod is hinged to the bottom surface of the air duct. The telescoping of the electric push rod can drive the air duct to tilt at different angles, so as to sprinkle water and maintain different heights of the exterior wall.

[0013] Preferably, the adjustment mechanism further includes an arc - shaped guiding frame fixedly connected to the upper surface of the water storage tank. An arc - shaped sliding frame is slidably connected to the outer surface of the arc - shaped guiding frame. The arc - shaped sliding frame is fixedly connected to the bottom surface of the adjustment frame. The arc - shaped sliding frame and the arc - shaped guiding frame play an auxiliary supporting role for the rotation of the adjustment frame.

[0014] The present utility model provides a device for maintaining a building concrete exterior wall, and the beneficial effects thereof are as follows:

[0015] 1. The building concrete exterior wall maintenance device can adjust the watering range of the air duct according to the width of the concrete exterior wall through the setting of a water tank, a spraying mechanism and an adjusting mechanism.

Finally, a mist of water is sprayed out by an atomizing nozzle. At the same time, the fan is controlled to operate. The fan blows air in the direction of the atomizing nozzle, so that the mist of water is sprayed onto the concrete exterior wall, so that the concrete exterior wall maintains suitable humidity and temperature conditions. In addition, watering maintenance can effectively slow down the shrinkage rate of concrete. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Please refer to Figure 1 , Figure 3 and Figure 4 An adjusting mechanism 3 is arranged above the water tank 1, and the adjusting mechanism 3 includes an adjusting frame 38 and a fixing frame 31 fixedly connected to the upper surface of the water tank 1, and a threaded rod 32 is rotatably connected to the inner wall of the fixing frame 31, and a round handle is arranged on the threaded rod 32 for the convenience of the operator to rotate.

[0029] The outer surface of the threaded rod 32 is threadedly connected to an internally threaded slider 33, and the internally threaded slider 33 is slidably connected to the inner wall of the fixed frame 31. The upper surface of the internally threaded slider 33 is rotatably connected to a first rotating rod 34. The top of the first rotating rod 34 is fixedly connected to a connecting plate 35, and the upper surface of the connecting plate 35 is rotatably connected to a second rotating rod 36. When the first rotating rod 34 rotates, it will drive the second rotating rod 36 to revolve through the connecting plate 35.

[0030] The top end of the second rotating rod 36 is fixedly connected with an anti-slip slider 37, and the anti-slip slider 37 is slidably connected to the inner wall of the adjusting frame 38. Under the sliding action of the adjusting frame 38 and the anti-slip slider 37, the second rotating rod 36 will drive the adjusting frame 38 to swing when it revolves. The upper surface of the adjusting frame 38 is fixedly connected with a U-shaped frame 39, and the inner wall of the U-shaped frame 39 is rotatably connected to two rotating shafts 310. The ends of the two rotating shafts 310 close to the wind tube 21 are fixedly connected to the outer surface of the wind tube 21, and the U-shaped frame 39 and the rotating shaft 310 play a supporting role in the tilting of the wind tube 21.

[0031] The bottom surface of the adjusting frame 38 is fixedly connected with a rotating column 311, and the bottom end of the rotating column 311 is rotatably connected to the upper surface of the water storage tank 1. The rotating column 311 plays a supporting role for the rotation of the adjusting frame 38.

When the motor 312 operates, it can drive the first rotating rod 34 to rotate through the driving gear 313 and the driven gear 314.

[0033] The upper surface of the adjusting frame 38 is hinged with an electric push rod 315. The top end of the electric push rod 315 is hinged to the bottom surface of the air duct 21.

[0035] Working principle: When the water pump 26 and the fan 22 are operating, atomized water will be sprayed onto the concrete outer wall for maintenance. At the same time, the motor 312 is controlled to operate, driving the first rotating rod 34 to rotate through the driving gear 313 and the driven gear 314, and causing the second rotating rod 36 to revolve. Under the sliding action of the anti-disengagement slider 37 and the adjusting frame 38, the adjusting frame 38 swings reciprocally, so that the blowing area of the air duct 21 becomes fan-shaped, and thus the spraying area on the outer wall is larger;

[0036] By rotating the circular handle on the threaded rod 32, the internally threaded slider 33 moves horizontally, driving the first rotating rod 34 and the anti-disengagement slider 37 to move horizontally. When the internally threaded slider 33 moves away from the rotating column 311, the fan shape of the swing of the adjusting frame 38 becomes smaller, reducing the spraying range. When the internally threaded slider 33 approaches the rotating column 311, the fan shape of the swing of the adjusting frame 38 becomes larger, increasing the spraying range. This device can adjust the spraying range of the air duct 21 according to the width of the concrete outer wall, increasing the spraying range and adjusting the spraying range according to the width of the outer wall, avoiding waste of water resources.
