Description

Technical Field

[0001] This invention relates to the field of ultraviolet sterilization and protection technology for cultural relics, and in particular to a device and method for protecting calligraphy and painting cultural relics with sterilization and disinfection functions. Background Technology

[0002] As precious carriers of thousands of years of Chinese civilization, calligraphy and painting artifacts are mostly made of fragile organic materials such as natural paper and silk, supplemented by sensitive components such as ink, mineral pigments, or plant dyes. They face multiple challenges in the long-term preservation process. On the one hand, the surface of the artifacts and the gaps between the fibers are extremely prone to the growth of microorganisms such as mold and bacteria. These microorganisms use the material of the artifacts as a nutrient source, which can cause problems such as mold and insect infestation, leading to the degradation of paper fibers, pigment loss, and staining of the painting, seriously damaging the integrity of the artifacts. On the other hand, pollutants such as oxygen, moisture, and dust in the air can accelerate the oxidation and aging of calligraphy and painting artifacts, causing paper to yellow and become brittle, and silk to lose strength. At the same time, the adhesion of pollutants can also affect the visual presentation of the artifacts and subsequent restoration work.

[0003] Traditional methods of sterilizing and disinfecting calligraphy and paintings often employ ultraviolet (UV) irradiation. However, UV light struggles to penetrate the contact area between the artwork and its support, creating sterilization blind spots that prevent the complete removal of microorganisms. Furthermore, under static irradiation, the tightly packed layers of paper in calligraphy and paintings hinder UV light penetration, further impacting sterilization effectiveness. Traditional methods of eliminating blind spots by flipping or moving the artwork can easily cause physical damage such as wrinkles and paint loss. Conventional UV sterilization environments lack effective protective measures, and UV irradiation may trigger oxidation reactions in the artwork's materials, accelerating its aging. Additionally, if the storage environment after sterilization cannot isolate oxygen and moisture, the artwork still faces the risk of secondary contamination and aging. Existing protective devices struggle to balance thorough sterilization, operational safety, and long-term preservation stability, failing to meet the refined needs of professional artifact preservation. Therefore, this paper proposes a calligraphy and painting artifact preservation device and method with sterilization and disinfection functions. Summary of the Invention

[0004] To overcome the problems existing in related technologies, this invention provides a protective device and method for calligraphy and painting cultural relics with sterilization and disinfection functions. Through the innovative design of alternating support by fixed support rods and movable support parts, there is no need to move or flip the cultural relics. Furthermore, by simply driving the movable support parts to lift them with gas pressure, the bottom area of ​​the calligraphy and painting that was originally covered can be fully exposed to ultraviolet light, thus solving the drawback of blind spots in the support surface in traditional ultraviolet sterilization.

[0005] To achieve the above objectives, the present invention provides a device for the preservation of calligraphy and painting cultural relics with sterilization and disinfection functions, including a sterilization and protection cabinet.

[0010] Preferably, the top of the sterilization protection cabinet is connected to an exhaust pipe, a second valve is installed on the exhaust pipe, and the partition is provided with a through hole for nitrogen gas flow.

[0011] Preferably, it also includes a blowing assembly, which includes a first air supply component and a swing component connected together. The first air supply component has a corresponding air supply section. During the ultraviolet sterilization process, nitrogen gas is introduced through the first air supply component and, in conjunction with the swing component, drives the air supply section to swing, so that the side of the calligraphy and painting document shakes and is lifted up.

[0012] Preferably, the first air supply component includes: Connected air supply branch pipe and air supply main pipe, wherein the air supply branch pipe has two opposing air guide ends; Two air outlet pipes are symmetrically hinged to both ends of the upper end face of the partition, and multiple air outlet nozzles are installed on the air outlet pipes; Two connecting hoses are respectively connected to the air guide ends of the corresponding air outlet pipe and air supply branch pipe.

[0014] This invention also provides a method for protecting calligraphy and painting cultural relics with sterilization and disinfection functions, which uses the above-mentioned device for protecting calligraphy and painting cultural relics with sterilization and disinfection functions and includes the following steps: S1. When sterilizing and disinfecting calligraphy and painting cultural relics, first open the cabinet door of the sterilization and protection cabinet, then place the calligraphy and painting cultural relics to be sterilized and disinfected on the calligraphy and painting cultural relic holder, first use multiple fixed support rods to support them, and then close the cabinet door.

After the air is exhausted, close the second valve on the exhaust pipe and the third valve on the first vent pipe. S3. Start the ultraviolet sterilization lamp to irradiate and sterilize the calligraphy and painting artifacts. After the set time, air or nitrogen is introduced through the second air supply component. The gas pressure pushes the piston upward, causing the push rod to drive the support block to rise, thereby lifting the calligraphy and painting artifacts a certain distance to adjust the bottom area that was blocked, and then perform ultraviolet sterilization treatment. S4. Simultaneously, nitrogen is introduced through the first air supply component, the flow rate of nitrogen sprayed from the air outlet is adjusted, and in conjunction with the movement of the swing component, the calligraphy and painting artifacts are gently blown from the side to help unfold the stacked parts and improve the uniformity and effect of ultraviolet sterilization.

[0015] To achieve the above objectives, the present invention provides...

[0016] The technical solution provided by this invention may include the following beneficial effects: 1. In this invention, the innovative design of alternating support by fixed support rods and movable support components allows for the exposure of the covered area by vertically adjusting the support surface at the bottom of the calligraphy and painting artifacts. This eliminates the need to move or flip the artifacts, minimizing the risk of friction, wrinkling, and paint loss of the calligraphy and painting paper. Furthermore, by simply using gas pressure to drive the movable support component to lift, the bottom area of ​​the calligraphy and painting that was originally covered can be fully exposed to ultraviolet light, solving the drawback of blind spots in the support surface during traditional ultraviolet sterilization.

[0017] 2. The present invention is equipped with a nitrogen blowing component, which, in conjunction with the swinging component, drives the air outlet pipe to swing at multiple angles, so as to blow the calligraphy and painting from the side with a gentle airflow, causing the multi-layered stacked paper to shake slightly and lift up, effectively separating the gaps between the layers, eliminating the blind spots of ultraviolet sterilization to a greater extent, and improving the uniformity and thoroughness of sterilization and disinfection.

[0018] 3. No complex manual intervention is required. The automatic alternating support and swing blowing are achieved through valve control, electric telescopic rod drive and other structures. The operation process is scientific and rigorous. In addition, the nitrogen flow rate and lifting height can be adjusted according to the material of the calligraphy and painting (such as Xuan paper, silk), which can meet the protection needs of calligraphy and painting cultural relics of different eras and materials. It is suitable for various scenarios such as museums, archives and private collections.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this invention. Preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings. Although preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the invention more thorough and complete, and to fully convey the scope of the invention to those skilled in the art.

[0024] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] Example 1: See Figures 1-7As shown, this invention proposes a protective device for calligraphy and painting artifacts with sterilization and disinfection functions, including a sterilization and protection cabinet 1. An exhaust pipe 2 is connected to the top of the sterilization and protection cabinet 1, and a second valve is installed on the exhaust pipe 2. A cabinet door is located on the front side of the sterilization and protection cabinet 1, and a ring of high-elasticity silicone rubber sealing gasket is embedded at the edge where the door contacts the cabinet body, achieving a seal when closed. A single piece of high-strength tempered glass with a thickness of 4mm-8mm is embedded in the center of the cabinet door. The glass surface is professionally treated with an anti-ultraviolet coating using multi-layer nanocomposite technology, resulting in a high UV blocking rate and preventing UV transmission, while also allowing staff to observe the work without... With the cabinet door open, the condition of the cultural relics can be observed. The interior of the sterilization and protection cabinet 1 is divided into an upper and lower sterilization and disinfection chamber 101 and a storage chamber 102 by a partition 104. Multiple ultraviolet germicidal lamps 3 are installed in the sterilization and disinfection chamber 101, fixed by multi-angle brackets, facing different directions inside the cabinet. Furthermore, to avoid damage to the calligraphy and painting relics from ultraviolet light, UVC short-wave ultraviolet lamps can be used, with their wavelength range strictly controlled between 200-280nm. Ultraviolet light in this band mainly acts on the DNA of microorganisms, achieving sterilization by destroying their structure, and will not degrade the fibers and pigments of the calligraphy and painting paper. For enhanced safety, the sterilization and disinfection chamber 101 can be equipped with a reflector made of high-purity aluminum mirror material, which has a high reflectivity and can effectively improve the utilization rate of ultraviolet rays and reduce energy loss. The storage chamber 102 is equipped with a protective drawer 103, the top of which has a passage pipe. The lower end of the side wall of the sterilization and protection cabinet 1 is connected to a first vent pipe 4 that allows nitrogen gas to enter the protective drawer 103. A third valve is installed on the first vent pipe 4, and a dust filter is also installed inside the first vent pipe 4. In addition, it includes a calligraphy and painting artifact support 6, located on the partition 104. The calligraphy and painting artifact support 6 includes a base part 61 and a second air supply component 62. The base part 61 includes... The system consists of multiple rows of fixed support rods 611 and multiple rows of movable support pieces 612. Each row of fixed support rods 611 and movable support pieces 612 has a certain density. Through the cooperation of multiple rows in the horizontal and vertical directions, a dense support matrix is ​​formed, which can stably support the calligraphy and painting artifacts without causing significant deformation when they are placed. The fixed support rods 611 and movable support pieces 612 are alternately arranged along the row direction. The second air supply component 62 is connected to the movable support piece 612. In the initial state, the supporting surface of the movable support piece 612 is lower than the upper end surface of the fixed support rod 611. Air is supplied to the movable support piece 612 through the second air supply component 62, which drives the supporting surface to rise, so that the calligraphy and painting artifacts are alternately supported by the movable support piece 612 and the fixed support rod 611.

[0026] The partition 104 is provided with a through hole for the flow of nitrogen (or other inert gas), specifically located near the edge of the partition 104.

[0027] See Figure 3 and Figure 5As shown, the upper end face of the partition 104 is provided with a groove 105, and the fixed support rod 611 and the movable support 612 are both provided in the groove 105.

[0028] See Figures 4-7 As shown, the movable support 612 is a component with elastic reset function. The movable support 612 specifically includes a hollow cylinder 6121 and a reset spring 6125. The hollow cylinder 6121 is axially hollow and is made of high-strength alloy material. The bottom end of the hollow cylinder 6121 is fixed to the bottom of the groove 105. A piston 6123 is slidably provided inside the hollow cylinder 6121. The outer circumferential surface of the piston 6123 is tightly fitted with the inner wall of the hollow cylinder 6121 to ensure that the piston 6123 has good sealing performance and can move smoothly without jamming when sliding inside the cylinder. A push rod 6124 is connected to the top of the piston 6123. A support block 6122 is fixed to the top of the push rod 6124. The reset spring 6125 is connected between the lower end face of the piston 6123 and the bottom of the groove 105. In the natural state of the reset spring 6125, the upper end face of the support block 6122 is lower than the upper end face of the fixed support rod 611.

[0029] See Figure 5 As shown, the second air supply component 62 includes a slot 622 formed inside the partition 104 and located below the groove 105. A guide hole 623 is provided at the bottom end of the groove 105 and directly opposite the hollow cylinder 6121. The diameter of the guide hole 623 is smaller than the inner diameter of the return spring 6125, so that the bottom end of the return spring 6125 can have a fixed position. A second air pipe 621 is connected to the slot 622, and a first valve 624 is installed on the second air pipe 621.

[0030] As described above, during the sterilization and disinfection of calligraphy and painting artifacts, first open the door of the sterilization and protection cabinet 1, place the calligraphy and painting artifacts to be sterilized and disinfected on the calligraphy and painting artifact support 6, and support them using multiple fixed support rods 611. Then close the cabinet door, open the second valve on the exhaust pipe 2, and introduce nitrogen gas into the sterilization and protection cabinet 1 through the first vent pipe 4 to replace and expel the air inside the cabinet. After the air is expelled, close the second valve on the exhaust pipe 2 and the third valve on the first vent pipe 4. Then, turn on the ultraviolet sterilization lamp 3 to irradiate and sterilize the calligraphy and painting artifacts. After a set time, introduce nitrogen gas (or air, since the gas will not enter the interior of the sterilization and protection cabinet 1) through the second vent pipe 621. After the gas enters the empty slot 622, it enters each hollow cylinder 6121 through the air guide hole 623. The gas pressure pushes the piston 6123 upward, causing the push rod 6124 to drive the support block 6122 upward, thereby lifting the calligraphy and painting artifacts upward a certain distance (usually). (A few millimeters to two centimeters) This avoids physical damage caused by friction and movement of the cultural relics, and allows the originally covered bottom area to be fully exposed to ultraviolet light. Then, the ultraviolet germicidal lamp 3 is turned on again for supplementary disinfection to ensure that all areas of the cultural relics achieve a thorough disinfection effect. In addition, the inert gas environment can effectively reduce the oxidation reaction that may be caused by ultraviolet radiation, and reduce the damage to the ink and paper fibers. After sterilization in the inert gas environment, the staff can put the sterilized cultural relics into the protective drawer 103 in the storage room 102 for storage. After the cultural relics are placed in and the cabinet door is closed, in order to extend the preservation life of the cultural relics, the storage room 102 also needs to be replaced with inert gas: nitrogen gas is introduced into the storage room 102 again through the first vent pipe 4 to replace the air in the storage room 102, reduce the oxygen content in the protective drawer 103, and inhibit the occurrence of problems such as oxidation and mold of cultural relics from the source, providing a long-term stable preservation environment for cultural relics.

[0031] The nitrogen supply can be stopped by the second vent pipe 621 and the valve on it can be opened. Under the reset action of the reset spring 6125, the support block 6122 can be moved down automatically.

[0032] Furthermore, the core advantages of this sterilization, disinfection, and preservation system lie in its ability to expose obscured areas by vertically adjusting the support surface at the bottom of the calligraphy and painting artifacts. Combined with ultraviolet disinfection in an inert gas environment, this system not only solves the problem of blind spots in the placement of calligraphy and painting artifacts in traditional ultraviolet disinfection but also minimizes secondary damage to the artifacts during the disinfection process. It avoids the risks of wrinkles and paint loss that may occur with conventional turning or lateral movement during disinfection. Moreover, it eliminates the need to open cabinet doors to turn the artifacts over, thus improving the efficiency of ultraviolet disinfection. Its operation process is scientific and rigorous, adaptable to calligraphy and painting artifacts of different eras and materials, and suitable for large-scale artifact preservation work in professional institutions such as museums and archives. At the same time, it can also meet the refined preservation needs of private collectors for precious calligraphy and paintings, providing a reliable guarantee for the long-term preservation of calligraphy and painting artifacts.

[0033] Example 2: See Figures 1-3 as well as Figures 8-9 As shown, the calligraphy and painting cultural relic protection device with sterilization and disinfection function also includes a blowing component 5. Its function is to solve the problem that ultraviolet rays cannot penetrate the tightly bonded layers of calligraphy and painting cultural relics by controlling nitrogen blowing and guiding dynamic airflow. Specifically, the blowing component 5 includes a first air supply component 51 and a swing component 52 connected together. The first air supply component 51 has a corresponding air supply part. During the ultraviolet sterilization process, nitrogen gas is introduced through the first air supply component 51 and the swing component 52 drives the air supply part to swing, creating gaps between the papers and providing a channel for ultraviolet rays to penetrate. This can effectively avoid the blind spots of sterilization caused by shadows in traditional static sterilization.

[0034] Among them, see Figures 8-9 As shown, the first air supply component 51 includes an air supply branch pipe 511, an air supply main pipe 512, and two air outlet pipes 513. The air supply branch pipe 511 and the air supply main pipe 512 are connected, and the air supply branch pipe 511 has two opposite air guide ends. A flow regulating valve is provided at the air guide end to precisely control the airflow output on one side. The two air outlet pipes 513 are symmetrically hinged to both ends of the upper end face of the partition plate 104. Multiple air outlet nozzles 514 are installed on the air outlet pipes 513. The air outlet nozzles 514 adopt a micro-aperture design (aperture of about 0.6-1.5mm), which can convert nitrogen into a fine airflow to avoid damage to fragile calligraphy and paintings caused by excessive airflow. In order to adapt to the swing requirements of the air outlet pipes 513, each air outlet pipe 513 is connected to the corresponding air guide end of the air supply branch pipe 511 with an aging-resistant connecting hose 515. The hose has good flexibility and can meet the multi-angle swing requirements of the air outlet pipe 513 without affecting the airflow transmission.

[0035] See Figures 8-9 As shown, the swinging component 52 includes a gear 522 and an electric telescopic rod 521. The gear 522 is fixed to the end of the hinge shaft of the air outlet pipe 513. The electric telescopic rod 521 adopts a micro stepping drive structure and is vertically fixed on the upper end face of the partition 104. Its telescopic accuracy can reach 0.1mm, which can realize small-amplitude fine telescopic movements. The electric telescopic rod 521 is vertically installed on the upper end face of the partition 104. A rack 523 is meshed on the gear 522. A protrusion 524 is connected between the top end of the rack 523 and the top end of the electric telescopic rod 521.

[0036] As described above, after the sterilization and disinfection process of calligraphy and painting artifacts is initiated, the controller (not shown) simultaneously activates the electric telescopic rod 521 to activate the blowing component 5. External nitrogen gas, after being depressurized and stabilized, enters the air supply branch pipe 511 through the main air supply pipe 512. After being regulated by the flow valves at both ends of the branch pipe, it is delivered to the air outlet pipe 513 through the connecting hoses 515 on both sides. Finally, it is sprayed onto the sides of the calligraphy and painting artifacts in the form of a gentle airflow from multiple air outlets 514. The operator can precisely adjust the nitrogen flow rate through the valves according to the material of the calligraphy and painting (such as Xuan paper, silk, etc.) to always maintain the airflow pressure within the safe range of 0.01-0.05MPa. This ensures that the paper can be effectively shaken while completely avoiding displacement or damage to the calligraphy and painting artifacts due to excessive wind force. At the same time, the controller controls the electric telescopic rod according to the preset program. The rod 521 performs periodic telescopic movements. When the electric telescopic rod 521 extends, it drives the rack 523 to move upward through the convex strip 524. The rack 523 drives the meshing gear 522 to rotate clockwise, which in turn drives the air outlet pipe 513 to swing upward around the hinge axis. When the electric telescopic rod 521 retracts, the rack 523 moves downward, the gear 522 rotates counterclockwise, and the air outlet pipe 513 swings downward synchronously. By setting the extension stroke of the electric telescopic rod 521 (usually controlled within 20-50mm), the swing angle of the air outlet pipe 513 can be limited to within ±15°, so that the nitrogen airflow can cover different areas on the side of the calligraphy and painting, further expanding the gap formation range between paper layers, ensuring that ultraviolet rays can act evenly on the fine parts of multi-layer calligraphy and painting, and improving the overall sterilization and disinfection effect.

[0037] This invention also proposes a method for protecting calligraphy and painting cultural relics with sterilization and disinfection functions, which uses the above-mentioned device for protecting calligraphy and painting cultural relics with sterilization and disinfection functions and includes the following steps: S1. When sterilizing and disinfecting calligraphy and painting cultural relics, first open the cabinet door of the sterilization and protection cabinet 1, then place the calligraphy and painting cultural relics to be sterilized and disinfected stably on the calligraphy and painting cultural relic support 6, first use multiple fixed support rods 611 to support them, and then close the cabinet door. S2. Open the second valve on the exhaust pipe 2 and introduce nitrogen into the sterilization protection cabinet 1 through the first vent pipe 4 to replace and exhaust the air in the cabinet. After the air is exhausted, close the second valve on the exhaust pipe 2 and the third valve on the first vent pipe 4. S3. Start the ultraviolet sterilization lamp 3 to irradiate and sterilize the calligraphy and painting artifacts. After a set time, air or nitrogen is introduced through the second air supply component 62. The gas pressure pushes the piston 6123 upward, causing the push rod 6124 to drive the support block 6122 to rise, thereby lifting the calligraphy and painting artifacts upward a distance to adjust the bottom area that is blocked, and then perform ultraviolet sterilization treatment. S4. At the same time, nitrogen gas is introduced through the first air supply component 51, the flow rate of nitrogen gas sprayed from the air outlet 514 is adjusted, and in conjunction with the movement of the swing component 52, the calligraphy and painting artifacts are gently blown from the side to help unfold the stacked parts and improve the uniformity and effect of ultraviolet sterilization.
