Description

Technical Field

[0001] This invention relates to the field of digital dissemination devices, and in particular to a digital dissemination device and method for cultural heritage information. Background Technology

[0002] Intangible cultural heritage is a precious legacy left to us by our ancestors. It has a strong cultural function of shaping people through ritual and music. Most of it is an expression of our ancestors' reverence and attitudes towards joy and sorrow, life and death, marriage, ancestors, nature, and heaven and earth, which arose from their labor and daily life. It is a living culture that satisfies people's natural, social, and spiritual needs. Its practicality is based on people-centeredness. However, in reality, with the development of society, the culture and content contained in intangible cultural heritage are gradually being valued. Through various platforms for display, intangible cultural heritage is being disseminated so that more people can learn about this information.

[0003] For example, a digital dissemination device for cultural heritage information, patent number "CN213960552U", relates to the field of information dissemination technology. It includes a frame, with signal disks fixedly installed on both sides of the upper surface of the frame. A front-facing display screen is fixedly installed on one side of the front surface of the frame, and a front plate is fixedly installed on the other side of the front surface. Several external sleeves are fixedly installed near the upper end of one side of the frame, and several cable sockets are opened inside the external sleeves on one side of the frame. The cable management mechanism includes a side-mounted sliding groove located at the edge of one side of the frame. This device not only effectively clamps external cables, achieving a better organizational effect and preventing excessive cable tangling, but also effectively prevents external dust from entering the frame and shortening the lifespan of internal circuit components.

[0004] However, in the current technology, when information is digitally displayed, it is usually full of technological sense, and all information is displayed through the screen. But if information about a certain culture is displayed, it is usually necessary to place pictures of works of the corresponding culture on the side, along with text descriptions and even some functional descriptions. When people receive cultural information, they can only watch it through the screen, so the experience and interest are not very high. Moreover, there is a certain difference between the pictures and the real objects, which reduces people's visual experience and sense of value. Summary of the Invention

[0005] The purpose of this invention is to address the problem in existing technologies where, when displaying information about a culture, it is usually necessary to place images of works related to that culture alongside textual descriptions and even some functional introductions. When people receive cultural information, they can only view it through a screen, which does not provide a high level of experience or interest. Furthermore, the images differ from the actual objects, which diminishes people's visual experience and appreciation of the value.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a digital dissemination device for cultural heritage information, comprising a base, a display screen, a top seat, and a support column. The base and the top seat are both circular in structure. The upper and lower ends of the support column are respectively located at the center of the top seat and the base. The display screen is fitted onto the outer wall of the support column. The base contains a power supply mechanism and a controller. The display screen is electrically connected to the controller and is powered by the power supply mechanism. A glass cover is provided between the outer ring of the base and the top seat. A rotating ring is provided above the base. A display rack for displaying exhibits is provided above the rotating ring. A cleaning mechanism for cleaning the glass cover is provided on the top seat above the inner side of the glass cover. A cleaning and protection mechanism is provided on the display rack. A storage and retrieval door for storing exhibits is opened on one side of the glass cover.

[0007] In a preferred embodiment, the display rack is provided with multiple racks and is equidistantly arranged above the rotating ring. The display rack includes an upper plate, a lower plate, and a connecting frame. The lower plate is connected to the upper plate at its upper center position via the connecting frame. The connecting frame is used to place exhibits. The connecting frame facilitates the placement of exhibits on the connecting frame for display.

[0008] In a preferred embodiment, the cleaning and protection mechanism includes a protective cover and a dehumidifier body. The dehumidifier body is located within the top seat. The protective cover is rotatably positioned at the edge between the upper and lower plates. The protective cover includes an outer half-cover and an inner half-cover. The inner arc surface of the outer half-cover slides against the outer side of the inner half-cover. The upper end of the inner half-cover has a connecting arc. The upper end of the connecting arc is rotatably connected to the lower part of the upper plate. A first gear meshes between the connecting arc and the outer half-cover. The upper end of the first gear is rotatably connected to the upper plate. The first gear is connected via a first... Driven by a motor, the outer and inner half-covers form a complete circle. When the protective cover is closed, the first motor drives the first gear to rotate, which in turn drives the connecting arc and the outer half-cover, which mesh with the first gear, to rotate synchronously in opposite directions. When each half-cover rotates a quarter circle, the end faces of the inner and outer half-covers fit together, effectively preventing water stains from entering and protecting the exhibits. Conversely, when they rotate outwards, they unfold for display. The included dehumidifier facilitates dehumidification of the interior of the device after cleaning, preventing damage to the exhibits caused by prolonged exposure to a humid environment.

[0009] In a preferred embodiment, a humidity sensor is provided below the top base, and a microcontroller is provided in the controller of the base. The humidity sensor is electrically connected to the dehumidifier body through the microcontroller. The humidity sensor can monitor the humidity inside the device in real time. When the humidity sensor detects that the humidity reaches a certain value, it transmits the monitoring signal to the microcontroller and converts it into an electrical signal, which is then transmitted to the dehumidifier body. The dehumidifier body then performs dehumidification operation inside the device.

[0010] In a preferred embodiment, the connecting frame is composed of two C-shaped frames joined vertically. The two C-shaped frames are arranged horizontally and on the same plane. Each C-shaped frame is equipped with a positioning clip, and a positioning block is located above the lower end of each C-shaped frame. A placement tray is vertically engaged on the positioning block. The C-shaped frames facilitate the placement of more three-dimensional exhibits, such as porcelain vases and bronzes. When placing these items, the center of the placement tray is engaged with the positioning block, ensuring the placement tray is in a stable horizontal position. The exhibit can then be placed on the placement tray. When displaying exhibits such as calligraphy, paintings, and embroidery, the exhibits can be held and positioned vertically by the positioning clips on the C-shaped frames. In this case, the two C-shaped frames are located on both sides and are on the same plane, preventing any abrupt changes that could damage the exhibits.

[0011] In a preferred embodiment, the cleaning mechanism includes a cylinder and a cleaning brush. The cleaning brush has a ring-shaped structure, and its outer wall is slidably in contact with the inner wall of the glass cover. The upper end of the cleaning brush is connected to the top seat via the cylinder. Multiple cylinders are provided and are arranged at equal intervals. By driving the cylinders, the cleaning brush can be moved up and down, thereby achieving up-and-down friction cleaning of the inner wall of the glass cover.

[0012] In a preferred embodiment, a water storage tank is provided on the base directly below the cleaning brush. The inner wall of the water storage tank is coated with a hydrophobic coating. The depth of the water storage tank is twice the height of the cleaning brush. An inlet and an outlet are respectively provided on the base on one side below the water storage tank. During cleaning, cleaning water can be introduced through the inlet, which in turn drives the cylinder to move the cleaning brush downward, so that the cleaning brush is inserted into the water storage tank. After the cleaning brush sucks water, the cylinder retracts, causing the cleaning brush to move up and down reciprocally, thereby cleaning the glass cover.

[0013] In a preferred embodiment, a water-squeezing ring is provided on the upper part of the outer side of the water storage tank. The water-squeezing ring has an obtuse triangular cross-section. When the cleaning brush is full of water and passes through the water-squeezing ring, the water-squeezing ring squeezes the cleaning brush and squeezes out the excess water. This prevents excessive water from dripping everywhere when cleaning the glass cover, which could cause water to get into the internal circuitry of the device and cause short circuits.

[0014] In a preferred embodiment, an assembly groove is provided at the lower edge of the top seat, and an end ring is rotatably engaged in the assembly groove. A second gear is provided between the side wall of the end ring and the assembly groove. The second gear meshes with one side of the end ring. The second gear is driven by a second motor. The second gear rotates due to the drive of the second motor, which in turn drives the end ring to rotate. The rotation of the end ring can drive the cylinder and cleaning brush below to rotate, which can realize the rotation cleaning operation of the cleaning brush when the cleaning brush is in the water storage tank.

[0015] This invention also provides a method for digitally disseminating cultural heritage information, comprising the following steps:

[0016] S1. Open the access door and manually rotate the rotating ring to move the display rack on the rotating ring to the access door position, and place the exhibit on the display rack;

[0017] S2. When placing three-dimensional exhibits, place the center of the placement tray onto the positioning block. At this time, the placement tray is in a stable state. Place the exhibit on the placement tray. When displaying exhibits such as calligraphy, paintings, and embroidery, the exhibits can be clamped and positioned by using the positioning clips on the C-shaped frame.

[0018] S3. Connect the display screen to the power supply and play different cultural introductions at the corresponding positions on the display screen. Rotate the rotating ring to move the different display racks on the rotating ring in front of the corresponding cultural introductions played on the display screen so that people can view them.

[0019] S4. Before cleaning, close the protective cover to protect the display rack inside;

[0020] S5. Water is introduced into the water tank through the inlet until it is one-third full. The extension cylinder moves the cleaning brush down into the water tank and completely submerges it in the water. The cylinder retracts and moves the cleaning brush up to clean the inner wall of the glass cover.

[0021] S6. After cleaning, open the water outlet to completely drain the water in the water tank, move the cleaning brush upward, and retract the cleaning brush into the assembly slot.

[0022] S7. When the humidity inside the device is too high during cleaning, the dehumidifier body is triggered and operates to dehumidify the inside of the device. The drain end of the dehumidifier body is connected to the outside of the device through a pipe.

[0023] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0024] This invention utilizes a display screen for cultural introductions and displays, as well as animated demonstrations. A display shelf is placed alongside the screen, holding exhibits that correspond to the information presented on the screen. Viewers can compare the exhibits to the actual objects, enhancing the immersive experience. By feeling the true size, texture, color, and details of the objects, viewers can closely observe and appreciate the culture, increasing their sense of connection and presence. Furthermore, viewers can more intuitively understand the historical origins, craftsmanship, and cultural background of the cultural heritage, thus gaining a deeper understanding and appreciation of its unique value, facilitating careful observation and experience.

[0025] This invention achieves a clean inner wall of the glass cover by driving the cleaning mechanism to clean the inside of the glass cover.

[0026] Before cleaning, the present invention can protect the display rack and the exhibits on it by driving the cleaning and protection mechanism to prevent water from splashing onto the exhibits and causing pollution.

[0027] This invention utilizes a C-shaped frame to facilitate the placement of more three-dimensional exhibits, such as porcelain vases and bronze artifacts. When placing these items, the center of the placement tray is engaged with the positioning block, ensuring the tray is in a stable, horizontal position. The exhibit can then be placed on the tray. For exhibits such as calligraphy, paintings, and embroidery, the exhibit can be positioned vertically using the positioning clips on the C-shaped frame. With the two C-shaped frames located on either side and forming a single plane, the exhibits will not be obtrusive or damaged, thus enhancing its practicality. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figure 1-10This invention provides a technical solution: a digital dissemination device for cultural heritage information, comprising a base 1, a display screen 2, a top seat 3, and a support column 4. Both the base 1 and the top seat 3 are circular. The upper and lower ends of the support column 4 are respectively located at the center of the top seat 3 and the base 1. The display screen 2 is fitted onto the outer wall of the support column 4. A power supply mechanism and a controller are located inside the base 1, and the display screen 2 is electrically connected to the controller. The display screen 2 is powered by the power supply mechanism. A glass cover 5 is provided between the outer rings of the base 1 and the top seat 3. A rotating ring 6 is located above the base 1, and a display rack 7 for displaying exhibits is located above the rotating ring 6. A cleaning mechanism for cleaning the glass cover 5 is located on the top seat 3 above the inner side of the glass cover 5. A cleaning and protection mechanism is located on the display rack 7. A storage door 8 for storing exhibits is located on one side of the glass cover 5. When digitally displaying information, cultural introductions and displays, or animation demonstrations, can be performed through the display screen 2. The display rack 7 is placed on one side of the cultural introduction display screen 2, and the display screen is placed on the display rack 7. The exhibits on display screen 2 are consistent with the actual objects. By comparing the content on display screen 2 with the real objects, people can have a more realistic experience. By feeling the real size, texture, color and details of the objects, people can observe and appreciate the culture up close, increasing the sense of intimacy and immersion in the exhibition. Moreover, the audience can more intuitively feel the historical origin, production process and cultural background of the cultural heritage, thereby gaining a deeper understanding and appreciation of the unique value of the cultural heritage. It is convenient for people to observe and appreciate carefully. During the long-term operation of this dissemination equipment, dust may accumulate on the inner wall of the glass cover 5 due to static electricity or other reasons. The outer wall of the glass cover 5 can be wiped manually by staff. If the inside is not wiped clean in time, it will affect people's viewing experience. The cleaning mechanism can be driven to clean the inside of the glass cover 5, so as to achieve a clean inner wall. Before cleaning, the cleaning protection mechanism can be driven to protect the display rack 7 and the exhibits on the display rack 7 to prevent water stains from splashing onto the exhibits and causing pollution.

[0042] like Figure 1-10 As shown, the display rack 7 has multiple racks that are equidistantly arranged above the rotating ring 6. The display rack 7 includes an upper plate 911, a lower plate 912, and a connecting frame 913. The lower plate 912 is connected to the upper plate 911 at the upper center position through the connecting frame 913. The connecting frame 913 is used to place exhibits. The connecting frame 913 facilitates the placement of exhibits for display.

[0043] like Figure 1-10As shown, the cleaning and protection mechanism includes a protective cover 101 and a dehumidifier body 102. The dehumidifier body 102 is located inside the top seat 3. The protective cover 101 is rotatably positioned at the edge between the upper plate 911 and the lower plate 912. The protective cover 101 includes an outer half cover 1011 and an inner half cover 1012. The inner arc surface of the outer half cover 1011 slides against the outer side of the inner half cover 1012. The upper end of the inner half cover 1012 is provided with a connecting arc 1013. The upper end of the connecting arc 1013 is rotatably connected to the lower part of the upper plate 911. A first gear 1014 meshes between the connecting arc 1013 and the outer half cover 1011. The upper end of the first gear 1014 is rotatably connected to the upper plate 911. The first gear 1014 is connected to the first motor 101. The outer half-cover 1011 and the inner half-cover 1012 can form a complete circle. When the protective cover 101 is closed, the first motor 1015 drives the first gear 1014 to rotate, which in turn drives the connecting arc 1013 and the outer half-cover 1011, which mesh with the first gear 1014, to rotate synchronously in opposite directions. When each rotates a quarter circle, the end faces of the inner half-cover 1012 and the outer half-cover 1011 fit together, which can effectively prevent water stains from entering and achieve the effect of protecting the exhibits. Conversely, it unfolds for display. The dehumidifier body 102 is provided to facilitate dehumidification of the inside of the device after cleaning, so as to avoid damage to the exhibits caused by prolonged exposure to a humid environment.

[0044] like Figure 1-10 As shown, a humidity sensor 11 is installed below the top base 3, and a microcontroller is installed in the controller of the base 1. The humidity sensor 11 is electrically connected to the dehumidifier body 102 through the microcontroller. The humidity sensor 11 can monitor the humidity in the device in real time. When the humidity sensor 11 detects that the humidity reaches a certain value, it transmits the monitoring signal to the microcontroller and converts it into an electrical signal, which is then transmitted to the dehumidifier body 102. The dehumidifier body 102 then performs dehumidification operation on the inside of the device.

[0045] like Figure 1-10 As shown, the connecting frame 913 is composed of two C-shaped frames 12 spliced ​​together vertically. The two C-shaped frames 12 are arranged horizontally and on the same plane. The C-shaped frames 12 are equipped with positioning clips 13, and the lower end of the C-shaped frames 12 is equipped with positioning blocks 14. The positioning blocks 14 are vertically engaged with placement trays 15. The C-shaped frames 12 facilitate the placement of more three-dimensional exhibits, such as porcelain vases and bronzes. When placing these, the center of the placement tray 15 is engaged with the positioning blocks 14. At this time, the placement tray 15 is in a stable horizontal state, and the exhibits can be placed on the placement tray 15. When displaying exhibits such as calligraphy, paintings, and embroidery, the exhibits can be clamped and positioned vertically by the positioning clips 13 on the C-shaped frames 12. At this time, the two C-shaped frames 12 are located on both sides and are on the same plane, so there will be no abruptness that could damage the exhibits.

[0046] like Figure 1-10As shown, the cleaning mechanism includes a cylinder 161 and a cleaning brush 162. The cleaning brush 162 has a ring structure, and its outer wall is slidably in contact with the inner wall of the glass cover 5. The upper end of the cleaning brush 162 is connected to the top seat 3 via the cylinder 161. Multiple cylinders 161 are provided and are arranged at equal intervals. By driving the cylinders 161, the cleaning brush 162 can be moved up and down, thereby achieving up-and-down friction cleaning of the inner wall of the glass cover 5.

[0047] like Figure 1-10 As shown, a water storage tank 171 is provided on the base 1 directly below the cleaning brush 162. The inner wall of the water storage tank 171 is coated with a hydrophobic coating. The depth of the water storage tank 171 is twice the height of the cleaning brush 162. A water inlet 172 and a water outlet 173 are respectively provided on the base 1 on one side below the water storage tank 171. When cleaning, cleaning water can be introduced through the water inlet 172, which will drive the cylinder 161 to move the cleaning brush 162 downward, so that the cleaning brush 162 is inserted into the water storage tank 171. After the cleaning brush 162 sucks water, the cylinder 161 retracts and drives the cleaning brush 162 to move up and down reciprocally, thereby cleaning the glass cover 5.

[0048] like Figure 1-10 As shown, a water-squeezing ring 174 is provided on the upper part of the outer side of the water storage tank 171. The water-squeezing ring 174 has an obtuse triangular cross-section. When the cleaning brush 162 is full of water and passes through the water-squeezing ring 174, the water-squeezing ring 174 squeezes the cleaning brush 162 to squeeze out excess water. This prevents excessive water from dripping everywhere when cleaning the glass cover 5, which could cause water to get into the internal circuit of the device and cause short circuits.

[0049] like Figure 1-10 As shown, an assembly groove 181 is provided at the lower edge of the top seat 3. An end ring 182 is rotatably engaged in the assembly groove 181. A second gear 183 is provided between the side wall of the end ring 182 and the assembly groove 181. The second gear 183 is meshed with one side of the end ring 182. The second gear 183 is driven by a second motor 184. The second motor 184 drives the second gear 183 to rotate, which in turn drives the end ring 182 to rotate. The rotation of the end ring 182 can drive the cylinder 161 and the cleaning brush 162 below to rotate, so that the cleaning brush 162 can be rotated and cleaned when it is located in the water storage tank 171.

[0050] Working principle:

[0051] S1. Open the access door 8 and manually rotate the rotating ring 6 to move the display rack 7 on the rotating ring 6 to the position of the access door 8, and place the exhibit on the display rack 7;

[0052] S2. When placing three-dimensional exhibits, the center of the placement tray 15 is locked onto the positioning block 14. At this time, the placement tray 15 is in a stable state, and the exhibits are placed on the placement tray 15. When displaying exhibits such as calligraphy, paintings and embroidery, the exhibits can be clamped and positioned by using the positioning clips 13 on the C-shaped frame 12.

[0053] S3. Connect the display screen 2 to the power supply, and play different cultural introductions at the corresponding positions on the display screen 2. Rotate the rotating ring 6 to rotate the different display racks 7 on the rotating ring 6 to the front of the corresponding cultural introductions played on the display screen 2, so that people can watch them.

[0054] S4. Before cleaning, close the protective cover 101 to protect the display rack 7 inside;

[0055] S5. Water is introduced into the water storage tank 171 through the water inlet 172. When the water is one-third full, the extension cylinder 161 drives the cleaning brush 162 to move down into the water storage tank 171 and completely submerge it in the water. The cylinder 161 retracts, driving the cleaning brush 162 to move up and clean the inner wall of the glass cover 5.

[0056] S6. After cleaning is completed, open the water outlet 173 to completely drain the water in the water storage tank 171, and move the cleaning brush 162 upward, causing the cleaning brush 162 to retract into the assembly tank 181.

[0057] S7. When the humidity inside the device is too high during cleaning, the dehumidifier body 102 is triggered. The dehumidifier body 102 operates to dehumidify the inside of the device. The drain end of the dehumidifier body 102 is connected to the outside of the device through a pipe.

[0058] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
