[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1-4 As shown in this embodiment, a surface cleaning device for ancient buildings includes a handle 1, a hollow rod 2, and an extension rod 3. The hollow rod 2 is fixedly connected to one end of the handle 1. One end of the extension rod 3 is located inside the hollow rod 2. A screw 5 is fixedly connected to the surface of the end of the extension rod 3 located inside the hollow rod 2. A groove 4 is provided on the surface of the hollow rod 2. The screw 5 is located inside the groove 4. A locking cap 6 is threaded to the outer side of the screw 5. An external thread is provided on the surface of the end of the extension rod 3 away from the hollow rod 2. An adjusting seat 7 is threaded to the outer side of this end. Depending on the cleaning height, the locking cap 6 can be loosened first, and the extension rod 3 can be extended from inside the hollow rod 2. After reaching the required height, the locking cap 6 can be tightened along the screw 5 to lock the current extension length of the extension rod 3.

[0022] The top of the adjusting seat 7 is provided with an adjusting groove 10. A connecting shaft 11 is rotatably connected inside the adjusting groove 10. Both ends of the connecting shaft 11 are fixedly connected with limit rings 12. The adjusting groove 10 is provided with a limit groove 13 that matches the limit ring 12. With the cooperation of the limit ring 12 and the limit groove 13, the connecting shaft 11 can be limited to the adjusting groove 10 without affecting the rotation of the connecting shaft 11.

[0023] A first micro motor 14 is fixedly connected inside the limiting groove 13. The output end of the first micro motor 14 is connected to one end of the connecting shaft 11. A connecting rod 15 is fixedly connected to the outside of the connecting shaft 11. When the first micro motor 14 is started, it will drive the connecting shaft 11 to rotate in the adjusting groove 10. The connecting rod 15 connects to the housing 8 to adjust the angle of the housing 8, thereby adjusting the orientation of the brush roller 9.

[0024] One end of the connecting rod 15 is fixedly connected to the housing 8, the inner side of one end of the housing 8 is rotatably connected to the brush roller 9, and the outer side of one end of the brush roller 9 is fixedly connected to the first transmission wheel 16.

[0025] The housing 8 houses a second micro motor 17. The output end of the second micro motor 17 is fixedly connected to a second transmission wheel 18. A transmission belt 19 is sleeved between the first transmission wheel 16 and the second transmission wheel 18. When the second micro motor 17 is started, it will drive the second transmission wheel 18 to rotate. Under the transmission of the transmission belt 19, the first transmission wheel 16 will rotate, thereby enabling the brush roller 9 to clean the surface of the ancient building.

[0026] Several control buttons are fixedly connected to the outer side of the top of the grip 1. Two of the control buttons are used to control the first micro motor 14 to rotate in the forward and reverse directions and adjust the angle of the housing 8. The other control button controls the second micro motor 17 to rotate the brush roller 9. The first micro motor 14 and the second micro motor 17 are both model 35BYJ412-B. The outer side of the grip 1 is equipped with an anti-slip sleeve to prevent the device from falling due to unstable grip when the user holds the grip 1.

[0027] This utility model provides a surface cleaning device for ancient buildings, the specific working principle of which is as follows:

[0028] First, loosen the locking cap 6 to adjust the height of the ancient building surface to be cleaned. Then, extend the extension rod 3 and hollow rod 2 into the hollow rod. Once the desired height is reached, tighten the locking cap 6 along the screw 5 to lock the current extension length of the extension rod 3. Then, start the second micro motor 17 to drive the second transmission wheel 18 to rotate. Under the transmission belt 19, the first transmission wheel 16 will rotate as well, so that the brush roller 9 cleans the surface of the ancient building. If it is necessary to change the cleaning angle of the brush roller 9 during cleaning, start the first micro motor 14 to drive the connecting shaft 11 to rotate in the adjustment groove 10. The connecting rod 15 connects to the housing 8 to adjust the angle of the housing 8, thereby adjusting the orientation of the brush roller 9.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
