Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cultural relic protection, and in particular to a cultural relic protection and restoration turntable and an operation method thereof. BACKGROUND

[0002] As a carrier of historical culture, the protection and restoration of cultural relics is of great importance. In the process of cultural relic restoration, cleaning the dust, dirt and other pollutants on the surface of the cultural relics is a fundamental and critical step. Traditional manual cleaning methods are inefficient, lack precision, and can easily cause secondary damage to the cultural relics. Therefore, it is an industry demand to improve the cleaning effect with the help of automated equipment. The cultural relic protection and restoration turntable, as a special device, can realize efficient and accurate cleaning of cultural relics through mechanical rotation and cooperation of auxiliary cleaning components. Its core principle is to drive the cultural relics to rotate through the rotation of the turntable, combined with components such as brushes and dust collectors, to complete the removal of pollutants in dynamic or static state, while reducing manual intervention and reducing operation risks.

[0003] However, the existing cultural relic protection and restoration turntable has the following shortcomings in actual application.

[0004] On the one hand, the operation convenience is insufficient: the start-stop control of traditional turntables relies on complex manual adjustment mechanisms, and frequent switching of power connection states is required, and independent control of rotation and dust collection functions cannot be achieved. For example, when the rotation of the turntable needs to be paused for fine cleaning, the power system often needs to be completely shut down, resulting in the simultaneous stop of the dust collection function, affecting the cleaning efficiency.

[0005] On the other hand, the function is single: the existing equipment usually only has a single "rotation + dust collection" mode, and cannot flexibly adjust the working state according to the material of the cultural relics, the degree of pollution, etc. For example, for fragile or special-textured cultural relics, high-speed rotation may cause damage, and traditional turntables lack low-speed or static cleaning modes; for the surface attachments of cultural relics that need to be preserved, the existing equipment cannot accurately control the start-stop of the dust collection function, and key substances may be accidentally sucked.

[0018] An operation method of the cultural relic protection and restoration turntable according to the cultural relic protection and restoration turntable in the claims comprises the following steps: when the cultural relics to be cleaned are placed on the turntable, three operation modes are mainly divided:

Detailed Implementation

[0037] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Reference Figures 1-10 Example 1: A turntable for the protection and restoration of cultural relics includes a workbench 1. A reducer 2 is installed at the bottom of the workbench 1, and the output shaft of the reducer 2 is fixedly connected to a main shaft 3 via a coupling. A large gear 4 is fixedly installed on the top of the outer wall of the main shaft 3, and a small gear 5 meshes on the outer wall of the large gear 4. A sleeve 6 is fixedly installed on the inner wall of the small gear 5. A dust collection component 7 is installed on the outer wall of the sleeve 6, and a powder suction pipe 9 is rotatably connected to the bottom outer wall of the sleeve 6 via a bearing. A powder suction hopper 10 is installed on the outer wall of one end of the powder suction pipe 9, and a brush 11 is fixedly connected to the top outer wall of the powder suction hopper 10 via screws.

[0039] In this embodiment, the reducer 2 installed at the bottom of the workbench 1 is the core power source, rigidly connected to the main shaft 3 via a coupling to ensure stable power transmission. The large gear 4 and small gear 5 at the top of the main shaft 3 form a gear pair, and the transmission ratio can be designed according to actual needs. The sleeve 6 on the inner wall of the small gear 5 is fixed by a key connection and rotates synchronously with the small gear 5. In the dust collection assembly 7 on the outer wall of the sleeve 6, the impeller 71 is evenly distributed circumferentially. When rotating, it forms an airflow in the housing 73, which draws dust into the dust collection pipe 9 through the powder inlet 72. The combination of the dust collection hopper 10 and the brush 11 allows the dust to be directly drawn into the dust collection hopper 10 when the brush 11 cleans the surface of the artifact, avoiding secondary stirring.

[0040] Through innovative mechanical structure design, independent control of the rotation of turntable 16 and dust collection function is achieved, forming three switchable working modes. In mode S1, reducer 2 drives main shaft 3 to rotate turntable 16, while large gear 4 and small gear 5 mesh to drive impeller 71 to rotate, forming negative pressure in dust collection hopper 10, realizing "rotation cleaning + synchronous dust collection", which is suitable for cleaning cultural relics with large area and high dust pollution. In mode S2, turntable start-stop switching component 20 separates clutch disc 13 from drive sleeve 12, stops the rotation of turntable 16, but retains the dust collection function, which can perform static fine cleaning of local details of cultural relics, avoiding damage to fragile parts caused by rotation.

[0041] In embodiment 2, a drive sleeve 12 is welded to the top outer wall of the main shaft 3, and a clutch disc 13 is slidably connected to the inner wall of the drive sleeve 12. A traction column 14 is welded to the top outer wall of the clutch disc 13, and a column 15 is slidably connected to the top outer wall of the traction column 14. A turntable 16 is welded to the top outer wall of the column 15, and the turntable 16 is embedded in the inner wall of the worktable 1. A chuck 17 is welded to the outer wall of the traction column 14, and a sealing disc 18 is rotatably connected to the outer wall of the chuck 17. A connecting rod 19 is welded to one side of the outer wall of the sealing disc 18, and a turntable start / stop switching component 20 is provided on the outer wall of one end of the connecting rod 19.

[0042] The drive sleeve 12 has equidistantly distributed rotary cutting grooves 23 on its inner periphery, and a positioning groove 24 is provided on one side of the rotary cutting grooves 23 on the inner wall of the drive sleeve 12. The clutch disc 13 has equidistantly distributed positioning blocks 25 welded around its outer periphery, and the positioning blocks 25 are slidably connected to the inner wall of the positioning groove 24. The traction column 14 has symmetrically distributed limiting blocks 26 welded on its outer wall, and a limiting groove is provided on the bottom outer wall of the column 15. The limiting blocks 26 are slidably connected to the inner wall of the limiting groove.

[0043] In this embodiment, the drive sleeve 12 is welded to the top of the spindle 3, and the rotary cutting groove 23 on the inner wall and the positioning groove 24 form a "rotation-positioning" composite track to ensure that the clutch disc 13 moves smoothly downward into the drive sleeve 12. When the positioning block 25 of the clutch disc 13 is embedded in the positioning groove 24, it can rotate synchronously with the drive sleeve 12.

[0044] When the clutch disc 13 is pushed upward by the turntable start-stop switching component 20, the positioning block 25 disengages upward, achieving power separation. The traction column 14 and the column 15 are connected by the limit block 26 and the limit groove to ensure that the turntable 16 rotates horizontally. The sealing disc 18 and the chuck 17 are rotated, allowing the connecting rod 19 to not obstruct the rotation of the chuck 17.

[0045] In embodiment 3, the dust collection assembly 7 includes an impeller 71, a powder inlet 72, and a housing 73. The impellers 71, which are evenly distributed, are welded to the peripheral outer wall of the sleeve 6. The powder inlet 72 is opened on the peripheral outer wall of the sleeve 6 and is located between two impellers 71. The housing 73 is disposed outside the impellers 71.

[0046] In this embodiment, the dust inlet 72 is located in the negative pressure area between adjacent impellers 71 to ensure effective dust intake. The dust enters the air filter 30 through the dust discharge pipe 29. The air filter 30 intercepts dust and particles through multiple layers of filter media (such as HEPA filter and activated carbon) to achieve solid-gas separation. The ball valve 27 of the dust suction hopper 10 controls the flow of fluid or adjusts the flow rate by rotating the valve core (ball). It can be opened and closed by rotating 90 degrees. The air inlet pipe 28 is connected to the inside of the dust suction hopper 10. When the ball valve 27 is closed, the air inlet pipe 28 automatically connects to the outside air to maintain the system air pressure balance.

[0047] The impeller 71 of the vacuuming assembly 7 is synchronously driven by the main shaft 3, eliminating the need for an independent power source and reducing energy loss. The meshing transmission between the large gear 4 and the small gear 5 not only achieves speed conversion but also drives the powder suction tube 9 and the brush 11 to move synchronously through the sleeve 6, ensuring consistency between cleaning and vacuuming.

[0048] In embodiment four, the turntable start / stop switching assembly 20 includes a vertical slide frame 201, a lower wedge block 202, a connecting frame 203, a spring 204, a horizontal slide frame 205, and an upper wedge block 206. The vertical slide frame 201 is welded to one outer wall of the worktable 1, and the lower wedge block 202 is slidably connected to the inner wall of the vertical slide frame 201. The end of the connecting rod 19 furthest from the sealing disc 18 is welded to the bottom outer surface of the lower wedge block 202. On the wall, the connecting frame 203 is welded to one side of the outer wall of the vertical sliding frame 201. The spring 204 is fixedly connected between the lower wedge block 202 and the connecting frame 203, and the spring 204 is located outside one end of the connecting rod 19. The horizontal sliding frame 205 is welded to the top outer wall of the connecting frame 203. The upper wedge block 206 is slidably connected to the inner wall of the horizontal sliding frame 205, and the upper wedge block 206 is tightly attached to the top outer wall of the lower wedge block 202.

[0049] The vertical slide frame 201 and the horizontal slide frame 205 of the turntable start / stop switching assembly 20 form a bidirectional guide rail. When the upper wedge block 206 is pushed to move along the horizontal slide frame 205 to the side of the lower wedge block 202, the wedge-shaped inclined surface forces the lower wedge block 202 to move upward, the spring 204 returns to its initial state, and the clutch disc 13 disengages from the drive sleeve 12. This structure utilizes the mechanical self-locking principle to ensure stable switching and avoid mode changes caused by accidental touches.

[0050] In this embodiment, the wedge block linkage structure of the upper wedge block 206 and the lower wedge block 202 of the turntable start-stop switching component 20, in conjunction with the spring 204, enables rapid switching of the power connection. When the upper wedge block 206 is pushed to move the lower wedge block 202 upward, the positioning block 25 of the clutch disc 13 disengages from the positioning groove 24 of the drive sleeve 12, ensuring that the turntable 16 completely stops rotating and avoiding rotational damage caused by misoperation. At the same time, mode S3 controls the opening and closing of the powder suction hopper 10 through the ball valve 27. When it is necessary to retain the material on the surface of the cultural relic, the ball valve 27 is rotated to seal the powder suction hopper 10 and the air intake pipe 28 is used to maintain airflow balance and prevent accidental suction. This dual protection mechanism of "mechanical clutch + airflow control" improves the safety and accuracy of equipment operation.

[0051] The bottom outer wall of the workbench 1 is fixedly connected to the box 21 by screws, and a strip groove 22 is opened on one side of the outer wall of the box 21. The connecting rod 19 is inserted through the inner wall of the strip groove 22. The top outer wall of the sleeve 6 is rotatably connected to an L-shaped support rod, and the L-shaped support rod is welded to the top inner wall of the box 21. The housing 73 is fixedly connected to the inner wall of the box 21 by screws.

[0052] A ball valve 27 is installed on the outer wall of the powder suction hopper 10 near the end of the powder suction pipe 9, and an air inlet pipe 28 is installed on the outer wall of one side of the ball valve 27. A dust discharge pipe 29 is fixedly connected to one side of the outer wall of the housing 73 through a flange, and an air filter 30 is installed on the outer wall of one end of the dust discharge pipe 29.

[0053] A PLC controller 8 is placed on the top outer wall of the workbench 1, and the PLC controller 8 is connected to the reducer 2 via a signal line.

[0054] Working principle:

[0055] When placing artifacts to be cleaned on the turntable 16, there are three main operating modes:

[0056] S1: The first operating mode is that the brush 11 cleans the rotating cultural relic while the dust suction hopper 10 sucks away the dust on the surface of the cultural relic. Specifically, the lower wedge block 202 is located at the bottom of the upper wedge block 206, and the spring 204 is in a compressed state. At this time, the clutch disc 13 is located in the drive sleeve 12, and the main shaft 3 is rotated through the reducer 2. Since the traction column 14 is embedded in the bottom of the column 15, the reducer 2 can control the turntable 16 to rotate together. At the same time, the large gear 4 and the small gear 5 mesh to control the impeller 71 to rotate, forming a negative pressure in the dust suction hopper 10, so that when the brush 11 cleans the cultural relic, the dust suction hopper 10 can suck away the dust.

[0057] In this mode, the power is fully engaged, suitable for regular cleaning. The rotation speed of the turntable 16 is adjusted by the reducer 2, and the suction power is determined by the speed of the impeller 71.

[0058] S2: The second operating mode is that the brush 11 cleans the stopped rotating cultural relic while the dust suction hopper 10 sucks away the dust on the surface of the cultural relic. Specifically, the upper wedge block 206 is pushed and the lower wedge block 202 moves upward, so that the upper wedge block 206 moves to the side of the lower wedge block 202. At this time, the spring 204 is in the natural state, the clutch disc 13 is separated from the drive sleeve 12, and the reducer 2 cannot drive the turntable 16 to rotate. Therefore, the cultural relic stops rotating. However, at this time, the large gear 4 and the small gear 5 continue to mesh to control the impeller 71 to rotate, so that when the brush 11 cleans the cultural relic, the dust suction hopper 10 can continue to suck away the dust.

[0059] In this mode, the power of turntable 16 is disconnected while vacuuming is retained, which is suitable for static and delicate operations, such as wiping the surface of cultural relics with cotton swabs in conjunction with vacuuming.

[0060] S3: The third operating mode is to rotate the artifact, but the dust suction hopper 10 stops sucking up the dust on the surface of the artifact. Specifically, the operation method for rotating the artifact can be referred to as S1. As for the dust suction hopper 10 stopping sucking up the dust on the surface of the artifact, the operation method is to rotate the handle on the ball valve 27 ninety degrees so that the valve body inside the ball valve 27 seals the dust suction hopper 10. At the same time, while sealing the dust suction hopper 10, the air inlet pipe 28 will automatically be in a ventilation state. The air inlet pipe 28 generates negative pressure to draw in air and keep the airflow unobstructed. At this time, when the brush 11 cleans the artifact, it can prevent the material on the surface of the artifact from being sucked into the dust suction hopper 10.

[0061] In this mode, turntable 16 is kept rotating, but vacuuming is turned off, which is suitable for scenarios where sensitive substances are prevented from being sucked up.

[0062] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
