Description

Technical Field

[0001] This utility model relates to the field of cultural relic protection, specifically to a self-circulating spray control device for waterlogged cultural relics. Background Technology

[0002] Traditional methods for preserving waterlogged artifacts typically involve direct immersion in a container to carry out each stage of the preservation process. However, most waterlogged organic artifacts are poorly preserved after excavation, exhibiting problems such as crumbling, cracking, and fragmentation. While traditional immersion methods can maintain the water saturation, they easily lead to further cracking and breakage, especially in woven artifacts. The key woven structures are highly susceptible to separation after prolonged immersion, causing irreversible damage. Furthermore, existing equipment is inadequate for preserving these fragile artifacts.

[0003] Specifically, existing spraying devices are unidirectional water sprayers, lacking a water circulation design, resulting in significant waste of soaking solutions and reagents. Humidification equipment is mostly timed or temperature-controlled, unable to respond to environmental changes in real time, easily leading to large humidity fluctuations that damage fragile cultural relics. Spraying devices from other industries lack compatibility with the vulnerable and precious characteristics of cultural relics, and cannot set differentiated humidity thresholds for different stages of conservation, potentially leading to uneven spray coverage, with some areas being overly wet or dry, causing secondary damage to the cultural relics.

[0004] Therefore, improvements to the existing spraying system are necessary.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this utility model, and therefore may contain information that does not constitute prior art known to those skilled in the art.

All other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features described in this specification can be combined with each other.

[0052] The self-circulating spray control device for waterlogged cultural relics of this utility model achieves spray circulation control for waterlogged cultural relics by setting up a spray area, a filtration circulation system and an intelligent control system inside the cabinet.

[0053] The following, combined with Figures 1 to 5 To illustrate the self-circulating spray control device for waterlogged cultural relics according to Embodiments 1 and 2 of this utility model.

[0054] Example 1

[0055] The following, combined with Figures 1 to 4 This invention describes a self-circulating spray control device 10 for waterlogged cultural relics according to Embodiment 1 of the present invention. Wherein, Figure 1 This is an external three-dimensional schematic diagram of the self-circulating spray control device 10 for waterlogged cultural relics in Embodiment 1. Figure 2 The cover 300 of the self-circulating spray control device 10 for waterlogged cultural relics according to Embodiment 1 of the present invention is shown. Figure 3 The diagram shows the structure of the intelligent control system 200 of the self-circulating spray control device 10 for waterlogged cultural relics according to Embodiment 1 of the present invention. Figure 4 This is an internal schematic diagram of a self-circulating spray control device 10 for waterlogged cultural relics according to Embodiment 1 of the present invention.

[0056] like Figure 1 As shown, in Embodiment 1 of this utility model, the top of the cabinet 100 of the self-circulating spray control device 10 for waterlogged cultural relics is provided with a cover 300, and a touch screen of the human-machine interface (HMI) of the intelligent control system 200 is installed on one side of the cabinet 100 to enable the user to control the self-circulating spray control device 10 for waterlogged cultural relics. An observation window 110 is provided on one side of the human-machine interface.

[0057] In this embodiment, the observation window 110 is connected to the cabinet wall of the cabinet 100 by a sealing strip. The light transmittance of the observation window 110 is preferably above 90% to facilitate real-time monitoring of the artifact preservation work inside the cabinet. Furthermore, to increase the observation range, the area of ​​the observation window 110 is preferably as large as possible. In this embodiment, the area of ​​the observation window 110 is set to allow observation of the spray area 120 and the soaking area 130 mentioned later. However, this invention is not limited to this; the position and size of the observation window 110 can be appropriately set as needed.

[0058] The specific structure of the cover 300 in this embodiment is shown in... Figure 2 .like Figure 2 As shown, the cover 300 can slide horizontally relative to the cabinet wall of the cabinet 100. Preferably, sealing strips are installed on the sides 310, 320, and 330 of the cover 300 that contact the cabinet wall of the cabinet 100 when closed. In this way, when the cover 300 is closed, a sealed space is formed at the top of the cabinet 100 to isolate external dust and inhibit the evaporation of liquid inside the cabinet 100. In addition, although not shown, a handle can be provided on the upper surface of the cover 300 for user operation.

[0059] Furthermore, the structural block diagram of the intelligent control system 200 in this embodiment is as follows: Figure 3 As shown, the intelligent control system 200 includes a user instruction receiving module 210 for receiving user instructions, a sensor signal receiving module 220 electrically connected to the sensor system described later and for receiving sensor signals, a control module 230 electrically connected to each mechanism and for controlling the operation of each mechanism, and an alarm module 240 for providing alarm prompts to the user. The alarm module 240 can issue an alarm prompt when a fault is detected or the received sensor signal exceeds a limit. The alarm prompt can be in the form of an audible and visual alarm combined with screen flashing, fault code display (in this embodiment, the alarm module 240 supports 20 types of fault self-diagnosis), etc., but this invention is not limited to these methods. In this embodiment, the user instruction receiving module 210 is integrated into... Figure 1 The touchscreen human-machine interface shown supports manual / automatic mode switching and has three preset processing programs for waterlogged cultural relics: moisturizing mode, desalination mode, and filling and consolidation mode. With this setup, users can easily and quickly operate the self-circulating spray control device 10 for waterlogged cultural relics, achieving automated control.

[0060] The following reference Figure 4 The internal structure of the self-circulating spray control device 10 for waterlogged cultural relics in Example 1 will be described in detail. It should be noted that, for ease of illustration, Figure 4 The intelligent control system 200 and some well-known structures (such as the water outlet at the bottom of the cabinet, the water inlet on the side wall of the cabinet, and necessary pumps) are omitted.

[0061] like Figure 4 As shown, the cabinet 100 of the waterlogged cultural relic self-circulating spray control device 10 includes a spray area 120 and an immersion area 130 located below the spray area 120. In this embodiment, a filtration and circulation area 140 for installing a liquid supply device 141, a filtration and circulation system 142, a heating system 143, and an intelligent control system 200 is also provided on one side of the spray area 120 and the immersion area 130. The filtration and circulation area 140 is separated from the spray area 120 and the immersion area 130 by a partition, but the bottom of the partition between the immersion area 130 and the filtration and circulation area 140 is open, allowing the immersion area 130 to communicate with the filtration and circulation area 140. This design prevents the supply device 141, the intelligent control system 200, and other mechanisms located inside the cabinet 100 from being corroded by the spray liquid in the spray area. However, this invention is not limited to this; a dedicated filtration and circulation area 140 may not be provided, and the various devices or systems may be placed in appropriate locations as needed. It should be noted that in this utility model, the filter circulation pipeline includes a spray pipe 122 and a pipeline between the liquid supply device 141 and the filter circulation system 142.

[0062] like Figure 4 As shown, a nozzle array 121 is provided at the top of the spraying area 120. The nozzle array 121 is connected to the outlet of the liquid supply device 141 through a spray pipe 122 to spray the surface of the artifact in a directional or comprehensive manner. The nozzle array 121 includes adjustable-angle rotating nozzles, the spray coverage radius of which is preferably adjustable within the range of 0.5-1 meter. This design allows for more comprehensive spraying of the artifact. Furthermore, the rotating nozzle of this invention includes a replaceable and detachable nano-atomizing nozzle (also called the first nozzle) and a water jet nozzle (also called the second nozzle). The nano-atomizing nozzle preferably has an atomization particle size of 10-100 micrometers, used during the moisturizing stage of artifact treatment to avoid direct impact of water droplets on the artifact surface. The water jet nozzle preferably has a spray pressure of 0.1-0.35 MPa, suitable for use during the reinforcement and protection stage of the artifact.

[0063] In this embodiment, a perforated shelf 123 for placing the artifacts to be treated is provided below the nozzle array 121. The spray liquid drips from the perforated shelf 123 onto the soaking area 130 below. The soaking area 130 may be provided with a container made of polytetrafluoroethylene to hold the soaking liquid.

[0064] In addition, such as Figure 4As shown, a filtration circulation system 142 is disposed within a filtration circulation area 140. The inlet of the filtration circulation system 142 is connected to the soaking area 130, and the outlet of the filtration circulation system 142 is connected to the inlet of the liquid supply device 141. In this embodiment, the filtration circulation system 142 is a physical filter with a filtration accuracy of 50 μm, but the present invention is not limited to this, and other filters can be used as needed. Thus, the filtration circulation system 142 filters the soaking liquid in the soaking area 130 and supplies it to the liquid supply device 141. The liquid supply device 141 transports the filtered soaking liquid to the nozzle array 121 as spray liquid for spraying treatment. The spray liquid after spraying treatment drips through the perforated plate 123 into the soaking area 130 below, becoming soaking liquid again, and is then filtered by the filtration circulation system 142, and so on.

[0065] In this embodiment, the heating system 143 includes an immersion heating module and a heating tube integrated into the bottom of the cabinet 100, the heating power of which is continuously adjustable within the range of 50-500W. However, as Figure 4 As shown, the heating system 143 is preferably located at the bottom of the filtration circulation area 140, thus avoiding the risk of damage to the artifacts due to excessively high local temperatures caused by its location in the soaking area 130.

[0066] In addition, the sensor system of the self-circulating spray control device 10 for waterlogged cultural relics in this embodiment may include a temperature and humidity sensor 151 disposed in the spraying area 120, a temperature sensor 152 disposed in the soaking area 130, a pressure sensor 153 disposed at the nozzle inlet of the nozzle array 121 for detecting the spray liquid pressure, and a liquid flow sensor 154, a pH sensor 155, and a conductivity sensor 156 disposed in the filter circulation pipeline for detecting the spray liquid flow rate. Specifically, the temperature sensor 151 can be an RS485 type temperature and humidity sensor with a humidity accuracy of ±2% RH and a temperature accuracy of ±0.5℃; the temperature sensor 152 can be a K-type thermocouple with a temperature measurement range of 0-80℃; the pressure sensor 153 can be a piezoresistive pressure sensor with a range of 0-1MPa and an accuracy of ±0.5% FS; and the liquid flow sensor 154 can be an electromagnetic flowmeter with a range of 0.1-10m³. 3 / h, with an accuracy of ±0.5%; pH sensor 155, i.e., pH meter, has a range of 0-14 pH and an accuracy of ±0.1 pH; conductivity sensor 156, also i.e., pH meter, has a range of 0-2000 μS / cm and an accuracy of ±1% FS. By setting up a sensor system connected to the intelligent control system 200's sensor signal receiving module 220, the liquid condition within the device can be monitored in real time to dynamically adjust the spray parameters. For example, when the sensor signal receiving module 220 receives a signal indicating that the humidity is below the set lower limit, the control module 230 increases the spray intensity; when the humidity is above the set upper limit, the spraying operation is paused and the alarm module 240 issues an alarm to the user, thereby achieving efficient utilization of the reagents while ensuring the safety of the cultural relics.

[0067] It should be noted that the location, number, and type of each sensor in the sensor system are not limited to this and can be adjusted as needed.

[0068] Thus, the waterlogged cultural relic self-circulating spray control device 10 of this embodiment integrates spraying, soaking, circulating filtration, solution heating and intelligent control functions, and is particularly suitable for cultural relic restoration operations at archaeological excavation sites and laboratories.

[0069] Example 2

[0070] The following combination Figure 5 To illustrate the self-circulating spray control device 10' for waterlogged cultural relics according to Embodiment 2 of this utility model. Figure 5 This is an internal schematic diagram of the self-circulating spray control device 10' for waterlogged cultural relics in Embodiment 2.

[0071] like Figure 5 As shown, the difference between the self-circulating spray control device 10' for waterlogged cultural relics in Embodiment 2 and the self-circulating spray control device 10' for waterlogged cultural relics in Embodiment 1 is that the self-circulating spray control device 10' for waterlogged cultural relics has longitudinal slide rails (not shown) symmetrically arranged on the side wall of the spray area. The perforated shelves 123, 123' are detachably installed in the cabinet 100 through snap-fit ​​parts set at the edge and matching the slide rails. The lower surface of the upper perforated shelf 123 is fixed with a nozzle array 121 by a magnetic base. In this way, the number and spacing of the perforated shelves can be flexibly adjusted according to the size, shape and quantity of the cultural relics.

[0072] It should be noted that in this embodiment, the number and spacing of the perforated layers are adjusted by using a slide rail and a snap-fit ​​structure. However, this utility model is not limited to this. For example, a structure with longitudinal serrations can be used, and the perforated layers can be directly placed between the serrations.

[0073] In this embodiment, a perforated shelf 123 is only provided in the spray area 120, but the present invention is not limited to this. More than one perforated shelf 123 can also be provided in the soaking area 130 as needed. In this embodiment, there are two perforated shelves in the spray area 120, but the present invention is not limited to this. When there are two or more perforated shelves in the spray area 120, except for the bottommost perforated shelf in the spray area 120, the lower surface of each perforated shelf in the spray area 120 can be fixed with a nozzle array via a magnetic base. This can greatly improve the processing efficiency.

[0074] The following describes the application of the self-circulating spray control device 10' for waterlogged cultural relics in Example 2 for the protection of waterlogged cultural relics.

[0075] Experimental Example 1: Moisturizing and Protecting Waterlogged Woven Artifacts

[0076] Lay the woven, waterlogged artifacts flat on the perforated shelves 123 and 123', and adjust the spacing between the perforated shelves 123 and 123' to 15cm.

[0077] Automatic water inlet for adding pure water;

[0078] Install nano-level atomizing nozzles with atomized particle size of 10-100 micrometers to prevent water droplets from directly impacting the surface of cultural relics. Activate the nano-atomizing spray for cyclic spraying.

[0079] Experimental Example 2: Reinforcement and Protection of Water-Saturated Wooden Cultural Relics

[0080] Add pure water through the automatic water inlet; add the appropriate proportion of reagent as needed (30% PEG4000 is used in this embodiment), and the control module 230 causes the heating system 143 to heat the soaking solution to 24°C until the reagent is completely dissolved.

[0081] The waterlogged wooden artifacts were classified, with the more fragile ones laid flat on the perforated shelves 123 and 123', with the shelf spacing adjusted to 15cm; the better-preserved ones were placed in the lower soaking area 130.

[0082] Install water spray nozzles with a spray pressure of 0.1-0.35 MPa; when the sensor signal receiving module 220 receives the sensor signal detected by the sensor system and determines that the local humidity is below 63%, the control module 230 automatically increases the spray frequency to prevent the bamboo slips from drying out and cracking.

[0083] Therefore, the self-circulating spray control device for waterlogged cultural relics of this utility model is suitable for the restoration of various waterlogged and fragile cultural relics.

[0084] In summary, according to the technical solution of this utility model, the following technical effects can be achieved:

[0085] (1) The water-saturated cultural relic self-circulating spray control device of this utility model avoids serious waste of reagent resources through water circulation design, and saves resources and is environmentally friendly.
