The invention has the beneficial effects that:

1. the installation frame that can reciprocate through the setting for can freely adjust the height of installation frame in the use, the high reduction back of installation frame, the bill-board that conveniently will treat to use is installed and is demonstrateed in the outside of installation frame. Simultaneously, the top plate and the bottom plate which can move up and down are arranged, the installation of the advertisement curtain is simple and rapid, and the subsequent advertisement curtain can be freely replaced. Reduce the height of installation frame, can avoid the staff to take place danger in the eminence when changing the installation bill-board, security when improving the construction.

2. Clean the mechanism through the setting for the bottom of work cleaning pad and the top contact of installation frame, wind-force blows the aerofoil and rotates at the top of girder, and cleaning pad can clean the top of installation frame, can clear up the rainwater and the snow at installation frame top, avoids rainwater and snow to cause the harm at the top to the installation frame, can not be to the weight increase of using the installation frame.

3. Through setting up the brush board for the aerofoil rotates the in-process cleaning pad and can promote the poker rod, drives the brush board and cleans along with second slider round trip movement to the outside of bill-board and scrapes. The brush board can be quick clear up the adnexed rainwater of bill-board outside and snow in sleet weather for the bill-board can be clear outside show all the time, plays good bandwagon effect. The phenomenon that rainwater and snow cover ice on the advertising board in cold weather is avoided, the wind power is utilized to drive the wind plate to rotate, energy consumption can be reduced, and continuous cleaning treatment can be carried out in work. Clear away the in-process of sleet, the brush board can also clear up the dust and other impurity of the outside accumulation of bill-board for the bill-board show is more clear, and the effect of show is better. In the environment that weather is fine, usable third telescopic link drives the aerofoil rebound for the bottom and the installation frame of cleaning pad break away from, the poker rod does not contact with cleaning pad, and the brush board can stop not using, reduces the loss of electric power, reduces the wearing and tearing of cleaning pad simultaneously.

4. The water storage cavity is arranged in the wind plate, so that rainwater or snow melting water can be stored in the water storage cavity in the wind plate in rainy and snowy weather. When the bill-board on the installation frame need be washd, the ponding of retaining intracavity portion can be sprayed on the bill-board, and the aerofoil drives the brush board and removes under the wind-force effect simultaneously, and the brush board can be in the in-process of water spray with the bill-board sanitization. Make the bill-board outside can obtain quick clearance by dust and impurity contamination after, and need not the staff and climb to the eminence clearance, it is safe high-efficient more. When the bill-board conflagration breaks out, the ponding of retaining intracavity portion can spray and put out a fire, can be quick put out a fire, avoids stretching of intensity of a fire, reduces the loss.

5. When in use, the telescopic end of the first telescopic rod can be used for extending downwards to drive the bottom plate to move downwards, so that the advertisement curtain is unfolded. The advertisement curtain can be printed with needed advertisements, and can be matched with the advertisement board above the advertisement curtain for use, thereby improving the effect of propaganda and increasing the advertisement space. When meetting strong wind weather or other bad weather, can drive roof rebound with first telescopic link, until the bottom butt of bottom plate and installation frame. Accomodate the advertisement curtain in the inside of installation frame, reduce the resistance of advertisement curtain, and then improve the stability of whole device, avoid the advertisement curtain to damage. When strong wind weather or other bad weather, can reduce the height of bill-board with the installation frame along girder lapse, reduce the risk of empting, improve the security performance of bill-board in use. The bottom plate and the top plate can prolong the height of the installation frame at the bottom of the installation frame, so that the center of gravity of the installation frame is reduced, and the stability of the advertising board is improved. Simultaneously, the counterweight can be arranged at the bottom of the mounting frame, so that the mounting frame is not easy to shake in work.

In rainy and snowy weather, the water storage cavity 11 inside the wind plate 10 can store rainwater or water melted by snow. When the advertising board on the installation frame 9 needs to be cleaned, the electromagnetic valve 19 is controlled to be opened by a worker, accumulated water in the water storage cavity 11 can be sprayed on the advertising board, meanwhile, the wind plate 10 drives the brush plate 7 to move under the action of wind power, and the brush plate 7 can clean the advertising board in the water spraying process. Make the bill-board outside can obtain quick clearance by dust and impurity contamination after, and need not the staff and climb to the eminence clearance, it is safe high-efficient more. When the bill-board breaks out a fire, the ponding of the water storage cavity 11 inside can spray and put out a fire, can be quick put out a fire, avoid stretching of the intensity of a fire, reduce the loss.

When in use, the telescopic end of the first telescopic rod 4 can be used for extending downwards to drive the bottom plate 6 to move downwards, so that the advertisement curtain 15 is unfolded. The advertisement curtain 15 can be printed with needed advertisements and matched with the advertisement board above, which can improve the effect of propaganda and increase the advertisement space. When meeting strong wind weather or other bad weather, can drive roof 27 rebound with first telescopic link 4, until bottom plate 6 and the bottom butt of installation frame 9. Accomodate advertisement curtain 15 in the inside of installation frame 9, reduce advertisement curtain 15's resistance, and then improve the stability of whole device, avoid advertisement curtain 15 to damage. In windy weather or other bad weather, can be with installation frame 9 along girder 1 downstream, reduce the height of bill-board, reduce the risk of empting, improve the security performance of bill-board in use.

The bottom plate 6 and the top plate 27 can extend the height of the mounting frame 9 at the bottom of the mounting frame 9, so that the center of gravity of the mounting frame 9 is lowered, and the stability of the billboard is improved. Meanwhile, the bottom of the mounting frame 9 can be used for balancing, so that the mounting frame 9 is not easy to shake in work.

The preferred embodiments of the invention disclosed above are intended to be illustrative only. The preferred embodiments are not intended to be exhaustive or to limit the invention to the precise embodiments disclosed. Obviously, many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and the practical application, to thereby enable others skilled in the art to best utilize the invention.
