Description

Technical Field

[0001] This invention relates to the field of cleaning equipment, and more particularly to a device for cleaning the surface of cultural relics. Background Technology

[0002] Cultural relics, as carriers of history, are mostly buried underground and require excavation and processing by professional archaeologists. However, because most relics are directly buried in the soil in harsh environments, their surfaces are usually covered with a large amount of mud, oil stains, rust, and so on after excavation. Therefore, they need to be cleaned using specialized equipment after excavation. Although there are now automated cleaning equipment such as ultrasonic cleaning and laser cleaning, most relics are still relatively fragile and require manual cleaning by professionals using brush-like tools.

[0003] The relevant technology can be found in Chinese Patent No. CN218905314U, which discloses a cultural relic cleaning table. The table includes a tabletop, a dust collection box fixedly connected to the bottom of the tabletop, an exhaust port on one side of the dust collection box, an air intake on the other side, an internal cavity, a filter plate fixedly installed on the inner wall of the dust collection box, an exhaust fan fixedly installed on the inner wall of the dust collection box, a suction hose fixedly connected to one end of the air intake, a handheld vacuum cleaner inserted into one end of the suction hose, a suction port on one end of the handheld vacuum cleaner, a suction head inserted into the inner wall of the suction port, and an internal cavity within the handheld vacuum cleaner. This device can store tools, provides quick and easy dust collection, and is convenient for cleaning most of the tricky locations of cultural relics. It eliminates the need to move the relics back and forth during the cleaning process.

[0004] Regarding the aforementioned techniques, when restorers clean the exterior of cultural relics, they typically place the relics on a workbench for cleaning. When cleaning different parts of the relics, the angle of placement needs to be adjusted. For some relics with complex shapes or fragments, it is difficult to maintain stability during placement. In such cases, restorers need to support and position the relics. Some relics are easily affected by temperature; if positioned by hand, it can easily damage them. Therefore, restorers also use tools such as tweezers and clamps to hold the relics and minimize contact with them. Prolonged work puts a significant strain on the restorers' hands, making the cleaning process quite inconvenient. Summary of the Invention

[0005] To improve the convenience of the cultural relic cleaning process, this application provides a surface cleaning device for cultural relics.

[0006] This application provides a device for cleaning the surface of cultural relics, which adopts the following technical solution: A surface cleaning device for cultural relics includes a workbench with a base for placing cultural relics at its upper end. A cleaning component for cleaning the cultural relics is located on one side of the base. The device also includes a placement ring located at the upper end of the base. A support platform has a support arm for supporting the placement ring. The placement ring has two sets of alternately arranged positioning tubes along its circumference. Each set of positioning tubes has at least two tubes. The positioning tubes are slidably connected to the placement ring along its diameter. The placement ring has a driving component that synchronously moves the same set of positioning tubes. The positioning tubes have threaded holes extending laterally. The perforations are arranged along the diameter of the storage ring, and the positioning tube is provided with an abutment rod that is threadedly engaged with the threaded hole; the first rotating wheel is located at the upper end of the support arm and is rotatably connected to the support arm in the transverse direction. The first rotating wheel has a through-hole in the transverse direction, and a second rotating wheel is arranged in the through-hole. The second rotating wheel is rotatably connected to the first rotating wheel in the vertical direction. A support column is fixed on the outer edge of the storage ring. The support column is arranged along the diameter of the second rotating wheel, and the support column passes through the second rotating wheel and is rotatably connected to the second rotating wheel around its own axis; the locking member is located between the support arm and the support column and is used to lock the relative movement between the support column and the support arm.

[0007] By adopting the above technical solution, when cleaning large cultural relics, the relics are directly placed on the placement base, and then the restoration personnel operate the cleaning device to carry out the cleaning work. For some small cultural relics, the relics are placed inside the placement ring of the slot. In the initial state, all positioning tubes are located close to the axis of the support tube. Under the guidance of the threaded hole, the operator rotates the abutment rod, so that all abutment rods cooperate to clamp and position the cultural relic. Each group of abutment rods moves independently, thus making it suitable for cultural relics of different shapes. The driving component is used to move all positioning tubes in the same group, which facilitates the loosening of the clamp on the cultural relic. Moreover, the two groups of positioning tubes work separately, improving the applicability to irregularly shaped cultural relics. The workbench supports the placement ring and the artifact via a support arm, which in turn supports the first rotating wheel, which in turn supports the second rotating wheel inside the opening. This allows the support column to move in both horizontal and vertical directions, and it can also rotate around its own axis, giving it multiple degrees of freedom. When the angle of the artifact needs to be adjusted, the operator can simply move the support column. After adjustment, the support column is locked in place by a locking mechanism, eliminating the need for the operator to hold the artifact while cleaning. This also facilitates easy adjustment of the artifact's placement angle, improving the convenience of cleaning artifacts.

[0008] Optionally, the driving component is provided in two sets, with each set corresponding to a different set of positioning tubes. The driving component includes a moving gear and a driven gear ring. The driven gear ring is sleeved on the outside of the storage ring and is rotatably connected to the storage ring on the same axis. The moving gear is rotatably connected to the storage ring and meshes with the driven gear ring. Several actuating pins are uniformly fixed on the end face of the driven gear ring along the axial direction. Each actuating pin corresponds to a positioning tube. A guide groove is provided on the side of the positioning tube facing the corresponding actuating pin. The guide groove is inclined along the circumference of the storage ring in a direction away from the axis of the storage ring. The actuating pin is located in the corresponding guide groove and fits against the inner wall of the guide groove.

[0009] By adopting the above technical solution, when the moving gear is rotated, it drives the corresponding driven gear ring to rotate under the support of the placement ring. When the driven gear ring rotates, it moves through the corresponding actuating post, which cooperates with the guide groove to drive the corresponding positioning tube to move. When cleaning the side of the cultural relic, the positioning tube and the abutment rod can be moved away from the cultural relic by the corresponding driving component, which makes it easier to clean the area blocked by the abutment rod. The two sets of positioning tubes work alternately, thus ensuring the clamping effect on the cultural relic when cleaning any area blocked by the abutment rod.

[0010] Optionally, the moving gear is slidably connected to a polygonal prism along the axial direction. The polygonal prism is coaxially arranged with the moving gear, and a positioning post is coaxially fixed at the lower end of the polygonal prism. The outer circle of the positioning post is provided with several limiting grooves along the axial direction. A positioning ring is fixedly connected to a positioning ring corresponding to the positioning post. The positioning ring is sleeved on the outside of the positioning post. A limiting block corresponding to the limiting groove is fixedly connected to the inner wall of the positioning ring. When the limiting block is located in the corresponding limiting groove, it fits against the inner wall of the limiting groove. An elastic element is provided between the polygonal prism and the moving gear. The pair of elastic elements applies a thrust close to the driven gear ring to the positioning post.

[0011] By adopting the above technical solution, in the initial state, the positioning post is located inside the positioning ring under the action of the elastic element. At this time, the limiting block and the limiting groove cooperate to position the positioning post and the polygonal prism. When it is necessary to rotate the moving gear, the polygonal prism is pushed along the axial direction, causing the positioning post to move out of the positioning ring. After contacting and positioning the positioning post, the moving gear can be driven to rotate through the polygonal prism. The moving gear can be locked, which helps to reduce the probability of the moving gear and the driven gear ring wobbling and improves the clamping effect on the cultural relic.

[0012] Optionally, a hollow tube is fixed circumferentially at the upper end of the storage ring. Several air holes are opened on the side of the hollow tube near the axis of the storage ring. An air box is provided on one side of the workbench. The air box is hollow and has an opening at one end that communicates with the outside. An air fan is provided at the opening. A flexible hose is connected to the end of the air box away from the opening. The flexible hose communicates with the hollow tube. A filter screen is provided inside the air box and is located between the flexible hose and the opening.

[0013] By adopting the above technical solution, when the fan is working, the gas in the air box flows, which in turn drives the airflow in the hollow tube through the hose, causing the airflow to blow towards the cultural relic. The airflow assists in cleaning the cultural relic, thereby improving the cleaning effect. At the same time, the filter screen helps to reduce the entry of external debris into the hose, reducing the probability of the cultural relic being affected during the cleaning process.

[0014] Optionally, the locking component includes a fixed tube, a straight plate, and an elastic element two. The fixed tube is sleeved on the outside of the support column and is slidably connected to the support column along the axial direction of the support column. The elastic element two is located between the fixed tube and the support column and is used to push the fixed tube closer to the second rotating wheel. Several insert plates are fixedly provided circumferentially on the side of the fixed tube close to the second rotating wheel. The second rotating wheel has several slots corresponding to the insert plates. The straight plate is rotatably connected to the first rotating wheel vertically, and the rotation axis of the straight plate is coaxial with the rotation axis of the second rotating wheel. A positioning block is slidably connected to the straight plate along its length. The positioning block is sleeved on the outside of the fixed tube and is rotatably connected to the fixed tube. A locking block is fixedly connected to the side of the positioning block close to the first rotating wheel. The first rotating wheel has several slots that match the locking block. The slots are distributed in an arc shape with the rotation axis of the second rotating wheel as the center.

[0015] By adopting the above technical solution, in the initial state, the fixing tube is close to the second rotating wheel under the action of the elastic element 2, so that the insert plate is inserted into the slot. At this time, the rotation of the support column around its own axis is restricted. When the fixing tube moves, it drives the positioning block to move, so that the positioning block drives the card block to be inserted into any card slot, thereby restricting the vertical rotation of the fixing column. When cleaning cultural relics, there is no need to support the support column, which is conducive to improving the convenience of cleaning.

[0016] Optionally, a sealing cover is hinged to one side of the workbench. When the sealing cover is fastened to the workbench, the storage seat and storage ring are all located inside the sealing cover. The support arm is foldable. The sealing cover is provided with an observation window. A transverse plate is slidably connected to the outer side of the sealing cover along its width direction. The transverse plate passes through the sealing cover and extends to the inner side of the sealing cover. A conveying pipe is connected to the transverse plate in a vertical rotation. A nozzle is fixedly installed at one end of the conveying pipe located inside the sealing cover. A water storage tank is fixedly installed at the lower end of the workbench. The water storage tank is connected to a water pipe. The water pipe is connected to the end of the conveying pipe away from the nozzle. A wastewater tank is provided at the lower end of the workbench. A drain hole is opened on the upper surface of the workbench, which is directly opposite the wastewater tank.

[0017] By adopting the above technical solution, when cleaning cultural relics is required, the support arm can be folded so that the placement ring avoids the sealing cover. The cultural relic can be positioned using the placement ring, or it can be placed directly on the placement base, as long as the cultural relic is positioned above the base. When the sealing cover is closed, the nozzle is directly opposite the location of the cultural relic. Under the action of the water pipe and delivery pipe, water in the water tank is sprayed out from the nozzle to clean the cultural relic. The cleaned water flows into the wastewater tank through the drain hole. During the cleaning process, the horizontal plate supports the delivery pipe, and the restorers can adjust the position and angle of the nozzle through the delivery pipe, thereby improving the convenience of cleaning.

[0018] Optionally, the side of the storage seat away from the sealing cover is vertically hinged to the workbench, and the side of the storage seat near the sealing cover is provided with a lifting component. The lifting component is used to drive the storage seat to rotate around the hinge. The side of the storage seat away from the sealing cover is provided with a baffle. The upper end of the baffle is hinged to the storage seat, and a filter groove is opened on the upper end surface of the baffle. The baffle has several drainage holes communicating with the filter groove along the vertical direction.

[0019] By adopting the above technical solution, the lifting component drives the placement seat to rotate, thereby tilting the placement seat to facilitate the discharge of wastewater above the placement seat. When the placement seat rotates, it pushes the baffle to move, and the wastewater flowing along the placement seat enters the filter tank and is discharged after being filtered through the drain hole. The baffle helps to prevent small pieces of cultural relics from sliding directly off the placement seat.

[0020] Optionally, a support member is provided between the sealing cover and the support platform. The support member is used to position the flip angle of the sealing cover. A movable frame is provided on the side of the sealing cover near the placement seat. The lower end of the movable frame is hinged to the sealing cover vertically. The sealing cover is fixedly provided with a mounting block for supporting the movable frame. When the maximum end face of the movable frame contacts the upper end face of the mounting block, the movable frame and the sealing cover are in a vertical state. A translation plate is slidably connected to the movable frame in the horizontal direction. A barrier net is provided inside the movable frame. One side of the barrier net is fixedly connected to the movable frame, and the other side is fixedly connected to the translation plate.

[0021] By adopting the above technical solution, after the sealing cover is flipped to a vertical position, it is positioned by the support component. In the initial state, the sliding plate is located on one side of the movable frame, and the barrier net is in the stored state. When the artifact is clamped by the placement ring, the movable frame is flipped so that it fits with the mounting block. At this time, the movable frame is located below the placement ring. The sliding plate is moved horizontally, thereby causing the barrier net to unfold and be positioned below the placement ring. The barrier net is beneficial for protecting the artifact and improves the safety of the artifact during the cleaning process.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When cleaning larger artifacts, place them directly on the mounting base, and then the restorers operate the cleaning device to perform the cleaning work. For smaller artifacts, place them inside the mounting ring of the slot. Initially, all positioning tubes are located close to the axis of the support tube. Guided by the threaded holes, the operator rotates the abutment rods, causing all abutment rods to work together to clamp and position the artifact. Each set of abutment rods moves independently, making it suitable for artifacts of different shapes. The driving component moves all positioning tubes in the same set, facilitating the loosening of the clamp on the artifact. The two sets of positioning tubes operate independently, improving the applicability to irregularly shaped artifacts. The workbench supports the placement ring and the artifact via a support arm, which in turn supports the first rotating wheel, which in turn supports the second rotating wheel inside the opening. This allows the support column to move in both horizontal and vertical directions, and it can also rotate around its own axis, giving it multiple degrees of freedom. When the angle of the artifact needs to be adjusted, the operator can simply move the support column. After adjustment, the support column is locked by a locking device, eliminating the need for the operator to hold the artifact for cleaning. This also facilitates adjusting the placement angle of the artifact at any time, improving the convenience of cleaning artifacts. 2. When the driving gear rotates, it drives the corresponding driven gear ring to rotate under the support of the placement ring. The rotation of the driven gear ring moves the corresponding actuating pin, which engages with the guide groove to move the corresponding positioning tube. When cleaning the side of the artifact, the corresponding driving component can move the positioning tube and the abutment rod away from the artifact, thus facilitating cleaning of the area obstructed by the abutment rod. The two sets of positioning tubes work alternately, ensuring effective clamping of the artifact when cleaning any area obstructed by the abutment rod. Attached Figure Description

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.

[0031] This application discloses a device for cleaning the surface of cultural relics.

[0032] Example: Reference Figure 1 and Figure 2 A surface cleaning device for cultural relics includes a workbench 1 and multiple support legs below the workbench 1. One side of the workbench 1 along its length is designated as the repair side, and cultural relic restorers work on the repair side of the workbench 1. Side plates are fixed to all sides of the upper end of the workbench 1 except for the repair side, which helps to prevent objects on the workbench 1 from rolling off.

[0033] Reference Figure 1 and Figure 2 A sealing cover 13 is vertically hinged to the side of the workbench 1 furthest from the repair side. In the initial state, the sealing cover 13 is upside down on the upper part of the workbench 1, thus covering the workbench 1. A support member 17 is provided between the workbench 1 and the sealing cover 13. The support member 17 is a positioning bolt, which passes through the sealing cover 13 and is threadedly connected to the sealing cover 13. The workbench 1 has multiple positioning holes evenly arranged in an arc shape around the hinge axis of the sealing cover 13. When the positioning bolt is inserted into any of the positioning holes, the sealing cover 13 is positioned.

[0034] Reference Figure 1 and Figure 2 The upper end of the workbench 1 is also provided with a support arm 12, which includes a first movable plate 121, a second movable plate 122, and a mounting plate 123. The first movable plate 121 is vertically hinged to the workbench 1. The second movable plate 122 is located at the upper end of the first movable plate 121 and is also hinged to the first movable plate 121. The mounting plate 123 is located at the upper end of the second movable plate 122 and is vertically hinged to the second movable plate 122. Locking nuts are provided between the first movable plate 121 and the workbench 1, between the first movable plate 121 and the second movable plate 122, and between the mounting plate 123 and the second movable plate 122. When the locking nuts are tightened, the locking nuts push the two adjacent parts to fit together, thereby achieving locking and positioning. The support arm 12 is adjustable, making it convenient for repair personnel to store the support arm 12 or adjust its state.

[0035] Reference Figure 2 and Figure 3 The upper end of the support arm 12 is provided with a storage ring 3, and a support column 33 is fixedly provided on the outer edge of the storage ring 3. The upper end of the mounting plate 123 is rotatably connected to a first rotating wheel 4 along the horizontal direction. The upper end of the first rotating wheel 4 has a horizontally opened opening, and a second rotating wheel 41 is provided in the opening. The second rotating wheel 41 is rotatably connected to the first rotating wheel 4 along the vertical direction. The support arm 12 supports the first rotating wheel 4 and the second rotating wheel 41. When the support arm 12 moves, it drives the first rotating wheel 4 and the second rotating wheel 41 to move. The support column 33 passes through the second rotating wheel 41 along the diameter direction of the second rotating wheel 41, and the support column 33 is rotatably connected to the second rotating wheel 41 around its own axis.

[0036] Reference Figure 2 and Figure 3 When the repair personnel move the support column 33, the support column 33 drives the storage ring 3 to move. The first rotating wheel 4 and the second rotating wheel 41 cooperate with the support column 33, allowing the storage ring 3 to rotate at multiple angles, which helps to improve the flexibility of the storage ring 3. The storage ring 3 is provided with two sets of positioning tubes 31 along the circumference. The two sets of positioning tubes 31 are alternately arranged, and both positioning tubes 31 pass through the storage ring 3 along the diameter direction of the storage ring 3 and are slidably connected to the storage ring 3.

[0037] Reference Figure 2 and Figure 3The positioning tube 31 has a threaded hole 311 along the diameter of the storage ring 3, and the positioning tube 31 is provided with an abutment rod 312 adapted to the threaded hole 311. The abutment rod 312 passes through the threaded hole 311 and is threadedly engaged with the threaded hole 311. The storage ring 3 is also provided with a driving component, which has two sets, one set of driving components corresponding to one set of positioning tubes 31. The driving component includes a moving gear 321 and a driven gear ring 322. The driven gear ring 322 is sleeved on the outside of the storage ring 3 and rotates coaxially with the storage ring 3. The two driven gear rings 322 in the two sets of driving components are parallel to each other, and multiple evenly arranged actuating rods are fixed on the side of the two driven gear rings 322 that are close to each other. The actuating rods on the two driven gear rings 322 are staggered in the vertical direction.

[0038] Reference Figure 3 and Figure 4 The positioning tube 31 and the corresponding toothed ring 322 have guide grooves 313 on their opposite sides. The guide grooves 313 are spirally arranged along the circumference of the storage ring 3 in a direction away from the axis of the storage ring 3. The actuating post 323 is located in the corresponding guide groove 313 and is slidably connected to the positioning tube 31 along the length of the guide groove 313. Under the limiting action of the storage ring 3, when the toothed ring 322 rotates, the actuating post 323 drives the corresponding positioning tube 31 to move, so that the positioning tube 31 drives the corresponding abutment rod 312 to move closer to or away from the axis of the storage ring 3.

[0039] Reference Figure 3 and Figure 4 The moving gear 321 is rotatably connected to the storage ring 3 and meshes with the driven gear ring 322 in the corresponding driving component. When the moving gear 321 rotates, it drives the corresponding driven gear ring 322 to rotate. When the driven gear ring 322 rotates, it drives the corresponding positioning tube 31 to move. During this process, all positioning tubes 31 in the other group are in a stationary state. The moving gear 321 is coaxially provided with a polygonal prism 34. The polygonal prism 34 passes through the moving gear 321 and is slidably connected to the moving gear 321. When the polygonal prism 34 rotates around its own axis, it drives the polygonal prism 34 to rotate.

[0040] Reference Figure 3 and Figure 5 A positioning post 341 is coaxially fixed at the lower end of the polygonal prism 34, and a support plate corresponding to the positioning post 341 is fixed at the lower end of the storage ring 3. The positioning post 341 passes through the support plate and extends to the lower end of the support plate. A plurality of evenly distributed limiting grooves 342 are opened circumferentially at the end of the positioning post 341 located below the support plate. A positioning ring 35 adapted to the positioning post 341 is fixedly connected to the support plate. The positioning ring 35 is sleeved on the outside of the positioning post 341 and is coaxial with the positioning post 341. A plurality of limiting blocks 351 adapted to the limiting grooves 342 are fixedly connected to the inner wall of the positioning ring 35. When the limiting blocks 351 are inserted into the limiting grooves 342, the rotation tendency of the positioning post 341 around its own axis is restricted.

[0041] Reference Figure 3 and Figure 5 An elastic element 343 is provided between the positioning post 341 and the placement ring 3. The elastic element 343 is a spring, which is sleeved on the outside of the positioning post 341, with one end of the spring abutting against the support plate and the other end abutting against the positioning post 341. The elastic element 343 applies a pushing force to the positioning post 341. In the natural state of the elastic element 343, the end of the positioning post 341 with the limiting groove 342 is located inside the positioning ring 35. It should be noted that the diameter of the end of the positioning post 341 with the limiting groove 342 is larger than the average diameter of the positioning post 341.

[0042] Reference Figure 3 When cleaning smaller artifacts, the artifact is placed inside the storage ring 3. At this time, all positioning tubes 31 are located close to the axis of the storage ring 3, and none of the positioning tubes 31 are in contact with the artifact. The restorer rotates the abutment rod 312, causing it to approach the artifact through the threaded hole 311. An abutment block, made of a flexible material such as rubber or silicone, is fixed to one end of the abutment rod 312 near the axis of the storage ring 3. The abutment block moves with the movement of the abutment rod 312, bringing it into contact with the artifact's surface. At this point, all the abutment rods 312 work together to clamp and position the artifact. Each abutment rod 312 moves independently, making it suitable for clamping artifacts of different shapes.

[0043] Reference Figure 1 and Figure 3 The upper end of the workbench 1 is equipped with a cleaning component 11. The cleaning component 11 can be an electric brush or other commonly used tools in this technical field, and is not limited here. The workbench 1 is equipped with a storage box for placing the cleaning component 11. When cleaning and restoring cultural relics, the restorer holds the support column 33 with one hand and uses the cleaning component 11 with the other hand to clean the cultural relic. During the cleaning process, the restorer moves the support column 33 to move the storage ring 3, thereby adjusting the posture of the cultural relic and cleaning different end faces of the cultural relic, while avoiding direct contact between the restorer and the cultural relic during the cleaning process.

[0044] Reference Figure 3 During the cleaning process, if it is necessary to clean the area where the artifact is in contact with the contact block, the restorer rotates the corresponding moving gear 321, causing the corresponding toothed ring 322 to move the positioning tube 31 away from the artifact. As the positioning tube 31 moves, it separates the contact block from the artifact via the abutment rod 312, thus clearing the area obstructed by the contact block. At this time, the other set of positioning tubes 31 remains stationary. After cleaning is completed, the moving gear 321 is rotated in the opposite direction, causing all the contact blocks to reset. The above operation is repeated, and then another driving component moves the second set of positioning tubes 31, which facilitates cleaning the artifact from various angles while it is clamped.

[0045] Reference Figure 1and Figure 3 A hollow tube 61 is fixed to the upper end of the storage ring 3, and the hollow tube 61 is coaxial with the storage ring 3. An air box 62 is installed on one side of the workbench 1. The air box 62 is hollow and contains a filter screen. An opening is provided on one side of the air box 62, and an air fan 621 is installed in the opening. When the air fan 621 rotates in the forward direction, it drives the airflow in the air box 62 to flow outward. When the air fan 621 rotates in the reverse direction, it drives the outside airflow to flow into the air box 62. An electric control button for controlling the rotation of the air fan 621 is provided on one side of the air box 62. A flexible hose 622 is connected to the upper end of the air box 62, and the end of the flexible hose 622 away from the air box 62 is connected to the hollow tube 61.

[0046] Reference Figure 1 and Figure 3 Multiple air holes 611 are evenly distributed on one side of the hollow tube 61 near the axis of the placement ring 3. When the air fan 621 rotates forward, it discharges the gas from the air box 62 during the cleaning process, creating a negative pressure in the hose 622. This negative pressure is transmitted to the hollow tube 61, where it absorbs the dust generated during cleaning through the air holes 611 and filters it through a filter screen. When the air fan 621 rotates in reverse, the hollow tube 61 blows gas through the air holes 611 onto the artifact, thus working in conjunction with the cleaning component 11 to clean the artifact, improving the convenience of cleaning.

[0047] Reference Figure 2 and Figure 6 A locking element is provided between the support column 33 and the support arm 12. The locking element includes a fixing tube 51, a straight plate 52 and an elastic element 53. The fixing tube 51 is sleeved on the outside of the support column 33 and is located on the side of the second rotating wheel 41 away from the storage ring 3. The fixing tube 51 is slidably connected to the support column 33 along its own axis, and the cross-section of the inner hole of the fixing tube 51 is polygonal. The support column 33 is provided with a sliding part that matches the inner hole of the fixing tube 51. Thus, when the support column 33 rotates around its own axis, it drives the fixing tube 51 to rotate.

[0048] Reference Figure 2 and Figure 6 The second elastic element 53 is a spring. One end of the spring is fixedly connected to the support column 33, and the other end is fixedly connected to the fixed column. In its natural state, the second elastic element 53 drives the fixed tube 51 to approach the second rotating wheel 41. On the side of the fixed tube 51 near the second rotating wheel 41, multiple insert plates 511 are fixedly connected axially. The second rotating wheel 41 has slots 411 corresponding to the insert plates 511. When the insert plates 511 are inserted into the slots 411, the rotation of the support column 33 around its own axis is locked.

[0049] Reference Figure 2 and Figure 6The straight plate 52 is rotatably connected to the first rotating wheel 4 in a vertical direction, and the rotation axis of the straight plate 52 is coaxial with the rotation axis of the second rotating wheel 41 around the first rotating wheel 4. A positioning block 521 is slidably connected to the side of the straight plate 52 away from its own rotation axis along its length direction. The positioning block 521 is sleeved on the outside of the fixed tube 51 and rotatably connected to the fixed tube 51. When the fixed tube 51 slides along its own axis, it drives the positioning block 521 to move along the length direction of the straight plate 52.

[0050] Reference Figure 2 and Figure 6 An arc-shaped plate 42 is fixedly connected to the side of the first rotating wheel 4 near the fixed tube 51. The arc-shaped plate 42 is coaxial with the rotation axis of the second rotating wheel 41, and multiple slots 421 are evenly provided on the outer edge of the arc-shaped plate 42. A positioning block 521 is fixedly connected to a locking block 522 corresponding to the slot 421. When the locking block 522 is located in the slot 421, the rotation of the first rotating wheel 4 around its own axis is locked, thereby restricting the vertical rotation of the support column 33. The locking device also includes a locking bolt 54, which passes through the mounting plate 123 and abuts against the first rotating wheel 4. When the restorer tightens the locking bolt 54, the locking bolt 54 locks the horizontal rotation of the first rotating wheel 4. When there is no need to adjust the angle of the artifact, the restorer can lock the movement of the support column 33 through the locking device. At this time, there is no need to support the support column 33, which improves the convenience of cleaning.

[0051] Reference Figure 1 A movable frame 18 is provided inside the sealing cover 13. A mounting block 134 is fixed on the side of the sealing cover 13 near the worktable 1. The movable frame 18 is located at the upper end of the mounting block 134 and is hinged vertically to the mounting block 134. When clamping and positioning the artifact using the placement ring 3, the sealing cover 13 is rotated to an angle perpendicular to the worktable 1, and the sealing cover 13 is supported and positioned by the support member 17. At this time, the movable frame 18 is flipped vertically so that it abuts against the mounting block 134, and the movable frame 18 and the sealing cover 13 are in a vertical state.

[0052] Reference Figure 1 and Figure 2 A sliding plate 181 is slidably connected to the movable frame 18 along its horizontal direction. A barrier net 182 is provided between the sliding plate 181 and the movable frame 18. In the initial state, the sliding plate 181 is located away from the support arm 12, and the barrier net 182 is in a retracted state. Before cleaning the artifact, the sliding plate 181 is moved towards the support arm 12, causing the sliding plate 181 to unfold the barrier net 182. At this time, the barrier net 182 is located below the storage ring 3, which helps to reduce the probability of the artifact accidentally falling off and causing damage.

[0053] Reference Figure 1 and Figure 2The upper end of the workbench 1 is also provided with a storage seat 2, which is located on the workbench 1 near the repair side. The side of the storage seat 2 away from the sealing cover 13 is vertically hinged to the workbench 1, and the side of the storage seat 2 near the sealing cover 13 is provided with a lifting component 21. The lifting component 21 includes a lead screw 212, a moving block 211, and a hinge rod 213. The moving block 211 is slidably connected to the workbench 1 in the direction of the sealing cover 13 pointing towards the repair side. The lead screw 212 is rotatably connected to the workbench 1 and is set in the sliding direction of the moving block 211. The lead screw 212 passes through the moving block 211 and is threadedly connected to the moving block 211. When the repair personnel rotate the lead screw 212, the lead screw 212 drives the moving block 211 to move.

[0054] Reference Figure 1 and Figure 2 The hinge rod 213 is located at the upper end of the moving block 211 and is hinged vertically to the moving block 211. The side of the hinge rod 213 away from the moving block 211 is also hinged vertically to the storage seat 2. When the moving block 211 moves, the hinge rod 213 causes the storage seat 2 to rotate, thereby adjusting the angle between the storage seat 2 and the worktable 1. When cleaning large artifacts, the artifacts are placed directly on the storage seat 2, which has circumferentially arranged sides to prevent the artifacts from rolling off.

[0055] Reference Figure 1 and Figure 2 A transverse plate 131 is slidably connected along the width direction to the side of the sealing cover 13 away from the support arm 12, and the support arm 12 has a clearance groove through which the transverse plate 131 passes and through the sealing cover 13. A conveying pipe 132 is vertically arranged on the transverse plate 131, and the conveying pipe 132 is slidably connected to the transverse plate 131 along its own axis, and is also rotatably connected to the transverse plate 131 around its own axis. When the transverse plate 131 moves, it drives the conveying pipe 132 to move. A nozzle 133 is fixedly installed at one end of the conveying pipe 132 inside the sealing cover 13, and the nozzle 133 moves when the conveying pipe 132 moves.

[0056] Reference Figure 1 and Figure 2 A water tank 14 is installed on the outside of the workbench 1. The water tank 14 is used to store purified water for cleaning cultural relics. A water pipe 141 connects the water tank 14 and the delivery pipe 132. A water pump is installed inside the water tank 14. When the water pump is working, purified water is input from the water pipe 141 and the delivery pipe 132 to the nozzle 133 and sprayed out from the nozzle 133. When it is necessary to rinse the cultural relics on the shelf 2, the restorer retracts the support arm 12 and the shelf ring 3 and closes the sealing cover 13. In the initial state, the nozzle 133 is directly opposite the shelf 2. The restorer can operate the nozzle 133 to rinse and clean different parts of the cultural relics by moving the transverse plate 131 and the delivery pipe 132.

[0057] Reference Figure 1 and Figure 2 The workbench 1 has a wastewater tank 15 at its lower end, and the workbench 1 has a vertically opening with a drain hole 16 that communicates with the wastewater tank 15. Water sprayed from the nozzle 133 slides down the base 2 and falls into the wastewater tank 15 through the drain hole 16. The sealing cover 13 has an observation window, which facilitates the restoration personnel to observe the condition of the cultural relics during the rinsing process.

[0058] Reference Figure 1 and Figure 2 A baffle 22 is provided on the side of the storage base 2 away from the sealing cover 13. A connecting plate is provided between the baffle 22 and the storage base 2, with one side of the connecting plate abutting against the baffle 22 and the other end abutting against the storage base 2. The baffle 22 is slidably connected to the worktable 1 along the length of the lead screw 212. When the storage base 2 rotates, the baffle 22 is moved by the connecting plate. A filter groove 221 is provided on the upper surface of the baffle 22, and a guide plate is fixedly connected to the side of the storage base 2 near the baffle 22. The guide plate is used to guide the wastewater on the storage base 2 to flow towards the baffle 22. The baffle 22 has multiple drainage holes 222 that communicate with the filter groove 221 along its vertical direction. When the wastewater on the storage base 2 flows into the filter groove 221, the baffle 22 performs secondary filtration of the wastewater through the drainage holes 222, thereby reducing the probability of cultural relic fragments being directly discharged with the wastewater.

[0059] The working principle of the artifact surface cleaning device in this application embodiment is as follows: the workbench 1 supports the placement ring 3 through the support arm 12. The placement ring 3 clamps and positions the artifact through the positioning tube 31 and the abutment rod 312. During the cleaning process, the restorer holds and moves the support column 33, causing the support column 33 to rotate under the support of the first rotating wheel 4 and the second rotating wheel 41, which facilitates the adjustment of the artifact's state at any time. When there is no need to adjust the position of the artifact, the degree of freedom of the support column 33 can be locked through the cooperation of the fixing tube 51, the positioning block 521 and the abutment bolt in the locking component, which helps to improve the convenience of cleaning artifacts.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
