For those of ordinary skill in the art, the specific meanings of the terms in the present utility model can be understood according to specific situations.

[0035] See Figures 1-7, this embodiment discloses a wall maintenance spraying device for construction projects, which includes a base 10, a water pumping component 20, a spraying component 30, a protection component 40 and a cleaning component 50. A water tank is provided on the base 10; the input end of the water pumping component 20 is connected to the output end of the water tank; the spraying component 30 is connected to the output end of the water pumping component 20, and the spraying component 30 is used to spray water onto the wall of the construction project; the protection component 40 includes a protection frame 41 and an observation window 42. The protection frame 41 is fixed to the base 10 and forms a protection cavity for accommodating construction workers. The observation window 42 is provided on the protection frame 41 and is used for construction workers to observe the situation outside the protection cavity when using the spraying component 30; the cleaning component 50 is provided outside the observation window 42 and is used to clean the observation window 42.

[0036] In the wall maintenance spraying device for construction projects of this solution, the water pumping component 20 pumps the water in the water tank 60 to the spraying component 30, and the spraying component 30 sprays it onto the wall. The construction workers are fully inside the protection frame 41, and there will be no splashing water stains. At the same time, the cleaning component 50 cleans the observation window 42 to ensure that the construction workers have a clear line of sight when spraying the wall. The spraying device of this solution has a simple structure, provides great convenience for the spraying operation of construction workers, and is suitable for wide application in the construction process.

[0037] See Figures 3-4 , the cleaning component 50 includes a moving plate 51, a cleaning pad 52 and a telescopic component. The protection frame 41 is provided with a sliding groove 411. The moving plate 51 is provided with a slider 511 that is slidably connected to the sliding groove 411. The cleaning pad 52 is arranged in the installation groove of the moving plate 51. The movable end of the telescopic component is connected to the moving plate 51 and is used to drive the cleaning pad 52 to clean the observation window 42.

[0038] In this embodiment, the sliding grooves 411 are opened on both sides of the edge of the observation window 42 in the first direction. The length of the cleaning pad 52 is the same as the width of the observation window 42 in the second direction and is attached to the outer surface of the observation window 42. The telescopic component drives the cleaning pad 52 to clean the observation window 42 along the first direction.

[0039] In this embodiment, the telescopic component includes a telescopic rod 53 and a connecting plate 54. The telescopic rod 53 is fixed to the edge of the observation window 42 in the second direction. The connecting plate 54 is respectively connected to the movable end of the telescopic rod 53 and the moving plate 51. The telescopic rod 53 is an electric telescopic rod 53 and is electrically connected to the controller 43 in the protection frame 41 to realize the cleaning of the observation window 42.

[0040] The protective frame 41 in the protection component 40 is installed on the top of the base 10 for use. When the staff uses the spraying device, they enter the interior of the protective frame 41 to control the spraying device. The staff observes the outside through the observation window 42 inside the protective frame 41, and turns on the water pump 21 through the controller 43. The through port 44 provides space for the control handle 36 to extend into the interior of the protective frame 41, enabling the staff to control the spraying angle and direction through the control handle 36 inside the protective frame 41. Through the installation of the protective frame 41, when spraying liquid on the wall, the liquid will not splash onto the staff, playing a protective role for the staff. The mounting plate provides a position for the installation of the electric telescopic rod 53. After being powered on, the electric telescopic rod 53 converts electrical energy into kinetic energy, thereby driving the cleaning component 50 connected to the telescopic end to move. The sliding groove 411 provides space for the sliding installation of the slider 511.

[0041] When the cleaning component 50 is in use, the connecting plate 54 is connected to the electric telescopic rod 53, so that the electric telescopic rod 53 can drive the moving plate 51 to move through the connecting plate 54. By installing the slider 511 in the sliding groove 411, the moving plate 51 can move stably, ensuring that the cleaning pad 52 installed through the installation groove on the back can stably fit the observation window 42, realizing the cleaning of the water stains on the surface of the observation window 42, and preventing the water stains from polluting the observation window 42 when the staff operates inside the protective frame 41, making it inconvenient for the staff to observe the outside.

[0042] The water stains after the cleaning component 50 cleans will flow into the interior of the liquid storage shell 55. The liquid storage shell 55 is used to collect the cleaned water stains, preventing the water stains after cleaning from flowing to other positions of the device and causing pollution. The water stains collected by the liquid storage shell 55 are discharged to the outside of the device through the discharge pipe 551. By installing the moving wheels 11, the device is more convenient to move. The water tank 60 provides a storage space for the water used for wall maintenance. When needed, the water pump 21 pumps out the water inside through the water suction pipe 22 and transports it to the installation pipe 34 through the transmission pipe 23.

[0043] See Figure 5 The water pumping component 20 includes a water pump 21, a water suction pipe 22, and a transmission pipe 23. One end of the water suction pipe 22 extends into the water tank 60, the other end of the water suction pipe 22 is connected to the water pump 21, one end of the transmission pipe 23 is connected to the water pump 21, and the other end of the transmission pipe 23 is connected to the spraying component 30.

[0044] See Figures 6-7, the spraying assembly 30 includes a support rod 31, a first rotating member, a second rotating member, a control handle 36, and a spraying nozzle. The support rod 31 is fixed to the base 10 and is disposed within the protective frame 41. The first rotating member is connected to the support rod 31, and the second rotating member is connected to the rotatable end of the first rotating member. Both the control handle 36 and the spraying nozzle are disposed on the second rotating member. The protective frame 41 is provided with a through opening 44 facilitating the extension of the spraying nozzle, and the spraying nozzle is connected to the output end of the water pumping assembly 20.

[0045] In this embodiment, the rotation direction of the first rotating member is perpendicular to the rotation direction of the second rotating member. The first rotating member is used to drive the spraying nozzle to rotate in the horizontal plane, and the second rotating member is used to drive the spraying nozzle to rotate in the vertical plane.

[0046] In this embodiment, the first rotating part includes a rotating rod 32 and a mounting bracket 33. One end of the rotating rod 32 is rotatably connected to the support rod 31, and the other end of the rotating rod 32 is fixedly connected to the mounting bracket 33.

[0047] In this embodiment, the second rotating part includes a mounting tube 34 and a rotating shaft 35. The rotating shaft 35 is disposed at both ends of the mounting tube 34, and the rotating shaft 35 is rotatably connected to the mounting bracket 33. The spraying nozzle extends out of the mounting tube 34, and the mounting tube 34 is provided with a connection port 341 for connecting to the water pumping assembly 20.

[0048] The mounting tube 34 is connected to the transmission tube 23 through the connection port 341, so that water can enter the mounting tube 34 and finally be sprayed onto the wall through the spraying nozzle mounted on the mounting tube 34. Under the installation of the rotating shaft 35, the control handle 36 can rotate the mounting tube 34, thereby changing the spraying angle of the spraying nozzle. The mounting tube 34 is installed inside the mounting bracket 33. Since the bottom of the mounting bracket 33 is connected to the support rod 31 through the rotating rod 32, the rotating rod 32 can rotate at the top of the support rod 31. The control handle 36 rotates the rotating rod 32, thereby changing the spraying direction of the spraying nozzle, and further making the device more flexible to use.

[0049] In this embodiment, the cleaning assembly 50 further includes a liquid storage shell 55. The telescopic member is disposed at the upper edge of the observation window 42, and the liquid storage shell 55 is disposed at the lower edge of the observation window 42. The liquid storage shell 55 is provided with a discharge pipe 551 for discharging sewage.

[0050] The usage method of the wall maintenance spraying device for construction engineering is as follows:

[0051] Step 1: First, the staff pushes the spraying device to the wall that needs to be sprayed and maintained. The installation of the moving wheels 11 makes it more convenient to move the spraying device. The operating staff enters the inside of the protective frame 41 to operate the spraying device and turns on the spraying device through the controller 43 for use;

[0052] Step 2: The staff observes through the observation window 42, enabling the staff to observe and spray and maintain the wall inside the protective frame 41. The staff adjusts the spraying position through the control handle 36. The rotating rod 32 is movably installed at the top of the support rod 31. Thus, through the rotation of the rotating rod 32, the spraying device can rotate left and right for spraying. At the same time, the installation pipe 34 for installing the spraying nozzle is connected through the rotating shaft 35, so that the installation pipe 34 can rotate, enabling the spraying nozzle to rotate up and down for adjustment;

[0053] Step 3: When spraying the wall, splashing will occur, and the splashed water stains will float onto the observation window 42, which will affect the use of the observation window 42. At this time, the electric telescopic rod 53 drives the cleaning component 50 at the output end to reciprocate on the front of the observation window 42. The cleaning pad 52 in the cleaning component 50 is used to clean the observation window 42. The water stains cleaned on the observation window 42 will flow down into the liquid storage shell 55 and then be discharged to the outside through the discharge pipe 551.

[0054] The working principle of the present utility model is as follows: First, the device is pushed to the wall to be sprayed through the rotation of the moving wheels 11. The staff operating the device enters the inside of the protective frame 41, and the water pump 21 is turned on by using the controller 43. The water pump 21 transmits the water stored in the water tank 60, and finally sprays it onto the wall through the spraying nozzle. The staff observes the outside through the observation window 42 inside the protective frame 41. The staff holds the control handle 36 to adjust the spraying direction and angle of the spraying nozzle. The water stains splashed onto the observation window 42 during spraying are cleaned by the cleaning component 50 to prevent the observation window 42 from being contaminated and affecting the staff's observation.

[0055] The above embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model should be subject to the appended claims.
