[0037] The outer frame 1 and the inner frame 2 are both made of metal materials to ensure the structural strength and then stably install the LED transparent display screen 3, the inner frame 2 can be fixedly installed in the outer frame 1 by the bolt fixing mode to effectively fix the transparent display screen, and the inner side of the outer frame 1 can also be installed on the preset frame of the glass curtain wall by the bolt fixing mode to effectively apply the LED transparent display screen 3 as the glass curtain wall.

[0038] The lifting grooves 11 arranged on the left and right sides of the outer frame 1 can ensure that the sliding support 41 stably lifts in the vertical direction, and when the sliding support 41 and the rolling brush 42 and the spray pipe group assembled thereon run to the top or bottom of the stroke, they can be stably stored and hidden in the corresponding lifting groove 11 to ensure that the content displayed by the LED transparent display screen 3 can be normally projected to the outside of the glass curtain wall.

[0039] The driving motor 46 can drive the lifting mechanism and the rotating mechanism to synchronously operate, the rolling brush 42 can be stably rotated by the rotating mechanism during the process that the lifting mechanism drives the sliding support 41 and the rolling brush 42 and the spray pipe group installed thereon to synchronously operate, and the spray pipe group sprays cleaning liquid to the contact position of the rolling brush 42 and the LED transparent display screen 3, so that the outer surface of the LED transparent display screen 3 can be effectively cleaned.

[0040] The cleaning liquid can be clean water or a mixture of clean water and detergent, and the sewage generated by cleaning can fall into the storage tank 12 arranged at the bottom of the outer frame 1 under the action of gravity, so that the sewage discharge hole 13 communicating with the storage tank 12 is arranged at the bottom of the outer frame 1 to ensure the normal discharge of sewage.

[0041] In order to ensure that the sliding support 41 can stably lift in the vertical direction in the lifting groove 11, the following technical solutions are provided.

[0042] The inner sides of the two groups of lifting grooves 11 are fixedly connected with the guide sliding rails 14 arranged in the vertical direction, and the two ends of the sliding support 41 are fixedly connected with the guide sliding seats 411 slidingly inserted with the guide sliding rails 14.

[0043] The guide sliding rails 14 and the guide sliding seats 411 are visually blocked and hidden by the lifting grooves 11 to ensure the appearance, and the cooperation of the guide sliding rails 14 and the guide sliding seats 411 can ensure that the sliding support 41 stably lifts in the vertical direction.

[0044] To ensure that the lifting mechanism can be stably assembled in the outer frame 1, and drive the sliding support 41 to stably lift along the vertical direction, the following technical solutions are provided.

[0045] The lifting mechanism includes two groups and is arranged in two groups of lifting grooves 11, and includes a driving synchronous wheel 431, a driven synchronous wheel 432, and a synchronous belt 433 wound on the driving synchronous wheel 431 and the driven synchronous wheel 432 and arranged in tension. The driving synchronous wheel 431 and the driven synchronous wheel 432 are arranged at the upper and lower ends of the outer frame 1, respectively, and the synchronous belt 433 is arranged in the lifting groove 11 and fixedly connected with the end of the sliding support 41.

[0046] When the combination of the driving synchronous wheel 431, the driven synchronous wheel 432 and the synchronous belt 433 is driven to operate by the driving motor 46, the synchronous belt 433 can drive the sliding support 41 to synchronously lift along the vertical direction. By adjusting the forward and reverse rotation posture of the driving motor 46, the lifting or lowering movement of the sliding support 41 can be controlled. The lifting groove 11 and the storage groove 12 can also block the lifting mechanism to ensure the aesthetic appearance.

[0047] The sliding support 41, the synchronous belt 433 and the guide slide 411 are fixedly combined by bolts, which facilitates disassembly and maintenance.

[0048] To ensure that the driving motor 46 can be stably installed in the outer frame 1 and achieve power connection with the lifting mechanism, the following technical solutions are provided.

[0049] The driving synchronous wheels 431 in the two groups of lifting mechanisms are coaxially fixed by the driving shaft 5. The driving motor 46 is fixedly installed at the top end of the outer frame 1. The driving shaft 5 is fixedly connected with a worm gear 51. The output shaft of the driving motor 46 is fixedly connected with a worm 461 matched with the worm gear 51.

[0050] The driving motor 46 is fixedly installed at the top of the outer frame 1, which can avoid the sewage flowing downward under the action of gravity from eroding, and ensure that the driving motor 46 can stably operate.

[0051] When the driving motor 46 operates, the combination of the worm 461 and the worm gear 51 can drive the driving shaft 5 to stably operate, and then drive the lifting mechanism to operate to adjust the lifting operation of the sliding support 41. The combination of the worm 461 and the worm gear 51 has the characteristics of speed reduction and torque increase, which ensures that there is enough power to drive the sliding support 41 and the components assembled thereon to stably lift. The combination of the worm 461 and the worm gear 51 also has the characteristics of one-way self-locking, that is, the power can only be transmitted from the worm 461 to the worm gear 51 in one direction. When the driving motor 46 is in a stopped state, the worm 461 and the driving shaft 5, the driving synchronous wheel 431 are in a locked state, which avoids invalid displacement of the sliding support 41.

[0052] The driving shaft 5, the worm 461, the worm wheel 51 and the driving motor 46 are visually blocked by the top storage groove 12, so as to hide them and ensure the overall aesthetics of the equipment.

[0053] In order to ensure that the rotating mechanism can be stably assembled in the outer frame 1 and combined with the rolling brush 42 and the driving motor 46, the following technical solutions are provided.

[0054] The rotating mechanism comprises a spline shaft 441, a driving bevel gear A 442 and a transmission bevel gear A 443. The spline shaft 441 is rotatably installed in one of the lifting grooves 11 and arranged in the vertical direction. The driving bevel gear A 442 is rotatably installed on the sliding support 41 and slidably connected with the spline shaft 441. The transmission bevel gear A 443 is fixedly connected to the end of the rolling brush 42 and engaged with the driving bevel gear A 442.

[0055] The top end of the spline shaft 441 is fixedly connected with a transmission bevel gear B 444, and the driving shaft 5 is fixedly connected with a driving bevel gear B 52 engaged with the transmission bevel gear B 444.

[0056] The rotating mechanism is also hidden in the corresponding lifting groove 11. When the driving motor 46 drives the driving shaft 5 to rotate, the spline shaft 441 can be driven to rotate stably through the combination of the driving bevel gear B 52 and the transmission bevel gear B 444.

[0057] During the vertical lifting movement of the rolling brush 42, the driving bevel gear A 442 and the transmission bevel gear A 443 driven by the sliding support 41, the spline shaft 441 can always transmit power to the driving bevel gear A 442, and then drive the rolling brush 42 to rotate stably through the transmission bevel gear A 443.

[0058] In order to ensure that the spray pipe group can effectively spray water on the contact position of the rolling brush 42 and the LED transparent display screen 3, the following technical solutions are provided.

[0059] The spray pipe group comprises a water supply pipe 451 and nozzles 452 uniformly assembled on the water supply pipe 451. The water supply pipe 451 is fixedly installed on the sliding support 41 and arranged on both sides of the rolling brush 42. The nozzles 452 are arranged towards the contact position of the rolling brush 42 and the LED transparent display screen 3. The water supply pipe 451 is connected with a water supply interface 453 arranged in the lifting groove 11.

[0060] A water receiving hose connected with the water supply interface 453 is arranged in the lifting groove 11. During the lifting movement of the spray pipe group driven by the sliding support 41, the water receiving hose can always supply water to the water supply pipe 451 through the water supply interface 453.

[0061] The water supply interfaces 453 and the rotating mechanisms are arranged in two groups of lifting grooves 11 on both sides of the outer frame 1, so that the water receiving hoses can be stably arranged in the corresponding lifting grooves 11, and spatial motion interference between the water receiving hoses and the rotating mechanisms is avoided.

[0062] It is apparent for a person skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced in the present application.
