[0002] External wall spraying during construction usually refers to the water spraying operation on the surface of the building's external wall. External wall spraying can also clean the dirt and dust on the surface of the building's external wall. At the same time, external wall spraying during construction is also a maintenance method for newly built or repaired external walls of concrete structures. This method helps the cement to fully hydrate, improves the strength and durability of the concrete, and at the same time reduces the generation of cracks and prevents the negative impacts caused by early drying.

By using a lifting mechanism and starting the third motor, the lifting plate can reciprocally lift on the outside of the square column.

[0004] Although the above technical solution can, by using a sliding mechanism and starting the second motor, adjust the spraying height of the sprayer while spraying, and can spray to the lowest and highest parts of the external wall, and by using a lifting mechanism and starting the third motor, the lifting plate can reciprocally lift on the outside of the square column, and at the same time, by using a swinging mechanism and starting the first motor, the sprayer above the rotating disc can reciprocally swing. The swinging mechanism and the lifting mechanism cooperate with each other to spray an external wall from top to bottom. However, when using the above spraying device to spray the external wall, due to the large area of the external wall in building construction, although the device can lift with one spray head, the spraying area at one time is limited, so it is easy to have the situation of low spraying efficiency, which affects the work efficiency of the staff. Therefore, those skilled in the art provide an external wall spraying device for building construction to solve the problems raised in the above background technique. Content of the Utility Model

Detailed Description of the Embodiments

[0022] In order to make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] Please refer to Figures 1 to 4 , the present utility model provides an external wall spraying device for building construction, which includes a bottom plate 1.

A water pump 11 is fixedly connected to the upper surface of the water storage tank 2. The input end of the power of the water pump 11 penetrates through the water storage tank 2 and extends to the inside of the water storage tank 2. The output end of the power of the water pump 11 is fixedly communicated with a diversion hose 14. One end of the diversion hose 14 away from the water pump 11 is fixedly communicated with a sealed rotary joint 16. The right end of the sealed rotary joint 16 is fixedly communicated with a connecting pipe 17. The right end of the connecting pipe 17 is fixedly communicated with a three-way spray pipe 19. The outer surface of the connecting pipe 17 is rotatably connected with a fixed frame 18. The bottom surface of the fixed frame 18 is fixedly connected with a lifting plate 4. The outer surface of the lifting plate 4 is slidably connected with the inner wall of the support frame 3. A rotary motor 20 is fixedly connected to the inner wall of the fixed frame 18. Two gears 21 are arranged inside the fixed frame 18. The outer surfaces of the two gears 21 are jointly meshed with a toothed synchronous belt 22. The inner wall of one of the gears 21 is fixedly connected with the outer surface of the connecting pipe 17. The inner wall of the other gear 21 is fixedly connected with the outer surface of the power output end of the rotary motor 20.

[0024] By setting the three-way spray pipe 19, when the water flow comes out of the rotating three-way spray pipe 19, it not only has a forward speed, but also has radial and tangential speed components due to rotation. This rotational movement causes the water flow to form a spiral path in the air, increasing the contact area between the water flow and the air, thereby expanding the spraying area.

[0025] Furthermore, a handrail 5 is fixedly connected to the upper surface of the bottom plate 1, and four universal wheels 6 are fixedly connected to the bottom surface of the bottom plate 1. By setting the handrail 5 and the universal wheels 6, it is convenient for the staff to push the device for movement, thus facilitating the staff to use it.

[0026] Furthermore, reinforcing blocks 8 are fixedly connected to the front and back surfaces of the support frame 3, and the bottom surface of each reinforcing block 8 is fixedly connected to the upper surface of the bottom plate 1. By setting the reinforcing blocks 8, the connection effect between the support frame 3 and the bottom plate 1 can be further improved, making their connection more stable.

[0027] Furthermore, a water injection pipe 9 is fixedly communicated with the upper surface of the water storage tank 2, and a plug 10 is slidably connected to the inner wall of the water injection pipe 9. By setting the water injection pipe 9 and the plug 10, it is convenient for the staff to inject water into the water storage tank 2 through the water injection pipe 9, thus facilitating the staff to carry out the spraying work.

[0028] Further, a protective cover 7 is fixedly connected to the outer surface of the water pump 11, and the bottom surface of the protective cover 7 is fixedly connected to the upper surface of the water storage tank 2. By providing the protective cover 7, it can provide a certain protective effect for the water pump 11, and at the same time further improve the firmness effect.

[0029] Further, a fixing block 15 is fixedly connected to the outer surface of the diversion hose 14, and the bottom surface of the fixing block 15 is fixedly connected to the upper surface of the lifting plate 4. By providing the fixing block 15, it can increase the stability at the connection end of the diversion hose 14 and the sealing rotary joint 16, enabling it to be used stably.

[0030] Further, a threaded rod 13 is threadedly connected to the inner wall of the lifting plate 4, and the bottom end of the threaded rod 13 is rotatably connected to the inner wall of the support frame 3. By providing the threaded rod 13, it can facilitate driving the lifting plate 4 to rise and fall, thereby helping the staff to quickly complete the spraying work on the outer wall.

[0031] Further, a forward and reverse motor 12 is fixedly connected to the top end of the threaded rod 13, and the upper surface of the forward and reverse motor 12 is fixedly connected to the inner top wall of the support frame 3. By providing the forward and reverse motor 12, it can provide the power required for lifting, thereby quickly driving the lifting plate 4 to rise and fall for spraying work.

[0032] Working principle: When in use, first the staff connects the power supplies of the water pump 11, the rotary motor 20, and the forward and reverse motor 12 to make them in a stable powered state. Then the staff injects an appropriate amount of water into the water storage tank 2 through the water injection pipe 9 for subsequent spraying work. Then the staff pushes the device to the outer wall through the handrail 5, and then turns on the water pump 11 and the rotary motor 20. After the water pump 11 is turned on, it can generate suction, and the water pump 11 can extract the water inside the water storage tank 2. Then the water flow can be transmitted through the diversion hose 14, and the transmitted water will enter the connecting pipe 17 through the sealing rotary joint 16. Finally, the water flow will be introduced into the three-way nozzle 19 through the connecting pipe 17 and sprayed out. At the same time, after the rotary motor 20 is turned on, it can generate power to rotate. The rotary motor 20 rotates to drive the gear 21 on its surface to rotate. When one gear 21 rotates, it can drive the toothed synchronous belt 22 and the other gear 21 to rotate, thereby driving the connecting pipe 17 and the three-way nozzle 19 to rotate quickly. The rotation of the three-way nozzle 19 can increase the speed of the water flow spraying out, and at the same time further expand the water coverage area, thereby improving the spraying efficiency of the device. Finally, turn on the forward and reverse motor 12, and the forward and reverse motor 12 can drive the threaded rod 13 to rotate, thereby driving the lifting plate 4 and the spraying device on the lifting plate 4 to rise and fall, so as to assist the staff to quickly complete the spraying work on the outer wall.
