Description

Technical Field

[0001] This utility model belongs to the field of cultural relic protection technology, specifically relating to a portable desalination device for metal cultural relics. Background Technology

[0002] Metal artifacts, especially unearthed bronze and iron artifacts, carry rich historical, artistic, and technological information, making them treasures of Chinese and even world cultural heritage. However, after long periods of burial, these precious metal artifacts are often extremely fragile. Corrosion is the primary threat to the integrity of metal artifacts, with corrosion caused by soluble salts such as chloride ions being particularly severe and widespread. These salts form an electrolyte environment inside the artifact, repeatedly dissolving and crystallizing under suitable temperature and humidity conditions, accelerating the electrochemical corrosion of the metal matrix, leading to "bronze disease" or active corrosion in iron artifacts, causing irreversible damage. Therefore, effective desalination treatment of metal artifacts to remove harmful soluble salts is a crucial prerequisite and core step for stabilizing their condition, delaying deterioration, and carrying out subsequent protection and restoration, as well as the foundation for long-term preservation.

[0003] Existing desalination techniques for metallic artifacts mainly involve placing the artifacts in a container (such as a plastic storage box), adding a desalination solution, and taking samples at irregular intervals to monitor the pH and chloride ion content of the desalination solution to assess the degree of desalination.

[0004] However, existing desalination technologies for metal artifacts have significant limitations: First, the parameter monitoring methods are limited, relying on manual sampling and having one-sided indicators, making it difficult to obtain multi-dimensional data on different depths of the desalination solution in real time; second, the desalination solution needs to be changed frequently, and the artifacts need to be moved frequently, which poses safety hazards to the artifacts during the movement, especially for fragile artifacts with severe corrosion; third, the internal space dimensions of some desalination containers are fixed, making them unsuitable for artifacts of different sizes and volumes, resulting in poor adaptability.

The bottom of the mobile frame 1 is fixedly equipped with casters 2 via spring shock absorbers. A desalination assembly 3 is installed on the top of the mobile frame 1. The desalination assembly 3 includes a desalination chamber 301, a cover 302, a partition groove 303, a partition plate 304, a threaded groove 305, several connecting rods 306, a clamp 307, an air inlet 309, and a sensor probe 3010. The desalination chamber 301, cover 302, and partition plate 304... The plate 304 is made of plexiglass, allowing staff to easily observe the internal desalination process. The desalination chamber 301 is placed on top of the mobile frame 1. Several support legs are fixedly connected to the bottom of the desalination chamber 301. The cover 302 is located on the top of the desalination chamber 301. The partition grooves 303 are arranged in a cross shape on the inner wall of the desalination chamber 301. The partition grooves 303 are equipped with sealing strips that fit the partition plate 304, which can play a sealing role. The partition plate 304 is sealed. The partition plates 304 are multiple and interlocked, with each other sealed and interlocked. Threaded grooves 305 are respectively opened on the inner wall of the desalination chamber 301 and the side surface of the partition plates 304. Several connecting rods 306 are threadedly connected to the inside of the threaded grooves 305. Both the clamps 307 and the waterproof camera 308 can be threadedly connected to the other end of the connecting rods 306. The air inlet 309 is opened above the threaded grooves 305 and located on the inner wall of the desalination chamber 301. The air inlet 309 is equipped with a sealing ring to provide a seal. The sensor probe 3010 is detachably installed inside the clamps 307. The threaded grooves 305 on the inner wall of the desalination chamber 301 and the side surface of the partition plates 304 are all distributed vertically and parallelly. The clamps 307 can interlock with each other. With the interlocking of the clamps, the operator can install sensors for parameters such as pH, chloride ion, conductivity, nitrate ion, and dissolved oxygen individually or simultaneously as needed to achieve synchronous monitoring and recording of different parameters.

[0024] The mobile frame 1 provides a supporting foundation for the entire device, and its casters 2 allow for flexible movement, facilitating transitions between different work environments. The desalination chamber 301 serves as the core space for desalination processing, and its cover 302 provides sealing protection against external interference. Cross-shaped partition grooves 303 and snap-fit ​​partition plates 304 divide the interior of the desalination chamber 301 into multiple independent areas, enabling simultaneous processing of multiple metal artifacts or accommodating metal artifacts of varying sizes, thus improving work efficiency. The threaded groove 305 provides an installation position for the connecting rod 306, allowing for the connection of the connecting rod 306... The threaded connection allows for flexible installation of the clamp 307 and the waterproof camera 308. The clamp 307 can firmly fix monitoring sensors of different specifications and types, such as pH sensors, conductivity sensors, dissolved oxygen sensors, chloride ion sensors, and nitrate sensors, ensuring stable sensor installation and facilitating disassembly and replacement. At the same time, sensor probes 3010 with different parameters can be selected according to work requirements. The waterproof camera 308 can observe and record the desalination of cultural relics in real time. The air inlet 309 is connected to the nitrogen cylinder 7, which can create an inert environment, reduce the oxidation of metallic cultural relics during the desalination process, and improve the desalination effect.

[0025] The desalination component 3 of this invention, through the cross-shaped partition grooves 303 and the snap-fit ​​partition plates 304 within the desalination chamber 301, allows for flexible adjustment of the internal space dimensions to accommodate metal artifacts of different sizes and volumes, significantly improving the adaptability of the device. Furthermore, the connecting rod 306 installed via the threaded groove 305 can flexibly fix the clamp 307 and the waterproof camera 308. The monitoring sensor probe 3010 inside the clamp 307 can acquire multi-dimensional data at different depths of the solution in real time, while the waterproof camera 308 can simultaneously record the state of the artifact, eliminating the reliance on manual sampling and enriching the means of parameter monitoring.

The threaded connection between the sleeve rod 3061 and the threaded groove 305, and the threaded connection between the telescopic rod 3062 and the sleeve rod 3061, allows for flexible adjustment of the length of the connecting rod 306 to accommodate clamping or observation needs at different distances.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, a handle 5 is fixedly connected to the top of the cover 302, which facilitates the operator to open or close the cover 302 and simplifies the operation process. An exhaust hole 4 is provided behind the handle 5 and on the inner wall of the cover 302. The exhaust hole 4 is connected to the interior of the desalination chamber 301. The exhaust hole 4 is equipped with a matching sealing plug, which can allow the air inside the desalination chamber 301 to be discharged when nitrogen is filled. The sealing plug helps the desalination chamber 301 to achieve a nitrogen-filled sealed environment, reduce the concentration of dissolved oxygen in the desalination solution, slow down the rate of pH change and corrosion in the desalination solution, and improve the desalination effect.

[0028] A placement rack 6 is fixedly connected to the top of the mobile frame 1 to secure the nitrogen cylinder 7 and prevent it from tipping over. The nitrogen cylinder 7 is detachably installed inside the placement rack 6 via a chain. A pressure reducing valve and a gas supply pipe are fixedly connected to the top of the nitrogen cylinder 7 in sequence. The two ends of the gas supply pipe are connected to the air inlet 309 and the nitrogen cylinder 7 via the pressure reducing valve, respectively. Nitrogen gas can be introduced into the desalination solution in the desalination chamber 301 to create an inert environment, reduce the dissolved oxygen concentration in the desalination solution, slow down the rate of pH change and corrosion in the desalination solution, and improve the desalination effect. A push rod 8 is fixedly connected to the top of the mobile frame 1. The push rod 8 facilitates the operator to push the device to move. A control panel 9 is fixedly installed at the front end of the push rod 8 by bolts. The control panel 9 can centrally set and control various parameters. Sensor operators can disassemble the control panel 9 by removing bolts, enabling centralized control of various functions of the device and achieving integrated operation, thus improving the ease of use and intelligence of the device. A drain pipe 10 is fixedly connected to the bottom of the mobile frame 1. A control valve is fixedly installed inside the drain pipe 10, and the drain pipe 10 is connected to the desalination tank 301, which can centrally discharge sewage and facilitate wastewater collection by operators. A cable routing hole 11 is opened on the inner wall of the desalination tank 301, and a sealing gasket is installed inside the cable routing hole 11. The cable routing hole 11 is used to discharge the wiring harness of the sensor probe 3010, and the sealing gasket seals the cable routing hole 11. A toolbox 12 is fixedly installed on the top of the mobile frame 1, which can hold tools for personnel to use.

[0029] The working principle and usage process of this utility model are as follows: The staff first pushes the mobile frame 1 with the push rod 8, and uses the universal wheels 2 with spring shock absorbers at the bottom of the frame to move the device to the work area.

[0030] Then, grasp handle 5 to open the box cover 302. According to the size and quantity of the metal artifacts to be processed, the appropriate partition plate 304 is snapped into the cross-shaped partition groove 303 inside the desalination box 301. The sealing strip inside the partition groove 303 ensures a seal, separating an independent processing area. Next, the metal artifacts are placed in the corresponding area, and then the connecting rod 306 is installed through the threaded groove 305 on the inner wall of the desalination box 301 and the side surface of the partition plate 304. The sleeve rod 3061 is threadedly connected to the threaded groove 305. The length can be adjusted by adjusting the spiral rotation of the telescopic rod 3062 inside the sleeve rod 3061. Then, according to the requirements, the pH, chloride ion, conductivity, nitrate ion, dissolved oxygen and other parameter sensors can be installed individually or simultaneously at the end of the connecting rod 306 through the clamp 307 to realize the synchronous monitoring and recording of different parameters. The sensor harness is led out through the cable hole 11 and sealed by the sealing gasket. At the same time, the waterproof camera 308 is snapped into the mounting block 3064 and the clamping block 3065 and the shooting angle is adjusted.

[0031] Afterwards, close the lid 302, open the pressure reducing valve of the nitrogen cylinder 7 secured by a chain on the placement rack 6, and allow nitrogen to enter the desalination chamber 301 through the air inlet 309 via the gas supply pipe, creating an inert environment. During the process, air is discharged through the exhaust port 4, and after the air is discharged, the exhaust port 4 is sealed with a sealing plug. The staff can centrally control the process by disassembling the control panel 9 on the push rod 8 with bolts, and obtain real-time sensor data and the status of the cultural relics captured by the waterproof camera 308 without manual sampling. After desalination, wastewater is discharged and collected through the drain pipe 10, and the cultural relics are taken out by opening the lid 302. If it is necessary to replace the sensor or camera, the relevant parts can be removed by disassembling the connecting rod 306 with threads. The toolbox 12 provides the necessary tools. The whole process is flexible and adaptable to different cultural relics, reducing the risk of moving cultural relics and improving efficiency and safety.
