[0002] Cultural relics are relics and remains left by humans in social activities with historical, artistic, and scientific values; in the work of protecting, excavating, and repairing cultural relics, it is often necessary to clean the cultural relics.

[0003] At present, when using the cultural relic cleaning device, a cleaning brush is often used to clean the dust attached to the outer wall of the cultural relic. After long-term use of the cleaning brush, the bristles on its outer wall gradually decrease and need to be replaced. After long-term use of the same handle, the staff may gradually adapt to the shape and weight of the handle and form a fixed usage habit. If a brand-new cleaning brush is replaced, at the beginning of use, the staff may be unfamiliar with its feel, which is likely to cause unstable operation and increase the risk of damaging the cultural relics. Therefore, it is necessary to redesign a cleaning device for cultural relic protection to solve the above problems. Content of the Utility Model

[0021] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Referring to Figures 1-5 , a cultural relic protection and cleaning device includes a cleaning brush sleeve 1 and a cleaning brush handle 2. Two guiding blocks 6 are fixedly connected to the outer wall of the cleaning brush handle 2. Two sliding grooves 5 are formed in the inner wall of the cleaning brush sleeve 1. The positions of the two sliding grooves 5 correspond to the positions of the two guiding blocks 6, and the shapes of the inner and outer walls match. The cleaning brush sleeve 1 is slidably connected to the outer wall of the cleaning brush handle 2, and the outer wall of the guiding block 6 is in close contact with the inner wall of the sliding groove 5. A fixing plate 3 is fixedly connected to the outer wall of the cleaning brush handle 2, and the end of the cleaning brush sleeve 1 abuts against the fixing plate 3. A limiting groove 13 is formed at the upper end of the guiding block 6, and a clamping block 15 is slidably connected in the limiting groove 13. The upper end surface of the clamping block 15 is inclined, and the outer wall of the clamping block 15 is in contact with the end of the cleaning brush sleeve 1. A reset mechanism for driving the clamping block 15 to reset is installed in the limiting groove 13; through the sliding connection between the cleaning brush sleeve 1 and the cleaning brush handle 2 and the cooperation between the guiding block 6 and the sliding groove 5, the replaceability of the cleaning brush sleeve 1 part is realized without replacing the whole, which continues the working habits of the staff for the shape and weight of the cleaning brush handle 2, reduces the risk of unstable operation, and also saves resources and costs.

[0023] The reset mechanism includes a first spring 14 fixedly connected to the inner bottom of the limiting groove 13, and the other end of the first spring 14 is fixedly connected to the clamping block 15. The inner wall of the limiting groove 13 and the outer wall of the clamping block 15 are both arc-shaped, and the outer wall of the clamping block 15 is in close contact with the inner wall of the limiting groove 13; by setting the first spring 14 and the clamping block 15, the cleaning brush sleeve 1 can be stably fixed on the cleaning brush handle 2 to ensure that the device can still work stably after replacement.

[0024] An air groove 7 is formed in the cleaning brush handle 2, and a piston 8 is slidably connected in the air groove 7. A nozzle 12 is installed on the outer wall of the cleaning brush sleeve 1 and is communicated with the inside of the air groove 7. A fixing ring 9 is fixedly connected to the inner wall of the air groove 7. A sliding rod 10 is fixedly connected to the outer wall of the piston 8, and a pulling block 4 is fixedly connected to the end of the sliding rod 10. A plurality of grooves are formed in the outer wall of the pulling block 4, and a plurality of second springs 11 are fixedly connected to the outer wall of the fixing ring 9. The ends of the plurality of second springs 11 are fixedly connected to the outer wall of the pulling block 4; the design of the air groove 7 and the nozzle 12 is added, and air flow blowing can be carried out simultaneously during the cleaning process, and dust and dirt can be removed more effectively during the cleaning process, especially at the uneven parts of the surface of cultural relics, improving the cleaning effect. The design of the second spring 11 enables the pulling block 4 to automatically reset, simplifying the operation.

[0025] In the present utility model, when the device is specifically used: when the cleaning bristles are worn or need to be replaced, the staff can adjust or replace them by sliding the cleaning brush sleeve 1. During the sliding process, the guiding block 6 slides smoothly in the sliding groove 5. One side of the clamping block 15 is inclined. When the cleaning brush sleeve 1 contacts the cleaning brush handle 2, it can be pressed downward until the cleaning brush sleeve 1 slides to the fixed plate 3. Subsequently, the clamping block 15 is reset under the action of the first spring 14 to ensure that the cleaning brush sleeve 1 can be firmly locked and prevent loosening during operation.

[0026] During the cleaning process, the staff can control the airflow in the air groove 7 by operating the pulling block 4. When pulling the pulling block 4, the sliding rod 10 drives the piston 8 to slide in the air groove 7, pushing the airflow to spray out through the nozzle 12. This airflow can effectively assist in removing dust and dirt on the surface of cultural relics, especially in uneven areas.

[0027] After each time the airflow is ejected from the nozzle 12, the pulling block 4 is automatically reset under the action of the second spring 11, and the piston 8 returns to the initial position to ensure the readiness for the next operation. At the same time, the cleaning brush sleeve 1 is stably held on the cleaning brush handle 2 under the cooperation of the guiding block 6 and the clamping block 15.

[0028] This device not only continues the operation habits of the staff, but also improves the cleaning efficiency. Especially in the cleaning of the surface of complex cultural relics, it reduces the risk of damaging cultural relics and realizes the versatility and easy maintenance of the device.

[0029] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present utility model.
