Abstract
Description
Technical Field
[0001] This utility model relates to the field of curtain wall technology, and in particular to a curtain wall for explaining cultural study tour routes. Background Technology
[0002] In cultural study tours, interpretive screens are crucial tools for conveying knowledge and showcasing culture. Currently, most interpretive screens used in cultural study tours are traditional static displays, presenting content solely through simple text and images. This fails to capture the attention of participants and fully satisfy their needs for exploration and knowledge. Furthermore, these screens are exposed to the outdoors for extended periods, suffering from wind, sun, and rain, resulting in significant dust accumulation. The lack of convenient and effective cleaning mechanisms leads to unclear displays and hinders information delivery. In addition, existing screens have limited functionality and cannot be integrated with modern technology to provide diverse experiences for study tours, such as interactive explanations or virtual scene displays. This significantly limits the teaching effectiveness and enjoyment of cultural study tours, necessitating innovation and improvement to adapt to the increasingly diverse needs of study tours.
[0003] For example, Chinese utility model patent (CN220731130U) discloses a cultural tourism route interpretation curtain wall, which solves the following problems: Traditional cultural tourism route interpretation curtain walls are generally installed outdoors, mostly on both sides of sidewalks. A lot of dust is generated during the process of people coming and going. The dust covering the surface of the cultural tourism route interpretation curtain wall will affect the tourists' viewing experience. Moreover, the existing cultural tourism route interpretation curtain walls are mostly cleaned by a limited number of cleaning personnel. It is impossible to quickly clean the relevant cultural tourism route interpretation curtain wall according to the actual interpretation needs, resulting in poor practicality of the existing cultural tourism route interpretation curtain walls.
[0004] The device includes a curtain wall box, inside which are cleaning components for dust removal and curtain wall components for display and explanation. The cleaning components include a transparent panel fixedly connected to the inside of the curtain wall box. Sliding boxes are fixedly connected to the inner top and bottom walls of the curtain wall box. Positioning rods are fixedly connected between the left and right inner walls of the sliding boxes. Sliding blocks are slidably connected to the outer sides of the positioning rods. Pullers are fixedly installed on opposite sides of the two sliding blocks. Metal rods are fixedly connected to both sides of the top sliding block. This cultural tourism route explanation curtain wall is easy for non-staff to clean and does not soil hands during cleaning, thus greatly improving its practicality.
[0005] When using the above technology, the following technical problems were found in the existing technology: the cleaning component of the current device only relies on the pressure of the soft brush to clean, which has limited effect on stubborn stains, and the distance between the device display panel and the first cleaning disc cannot be adjusted. The pressure of the first cleaning disc on the display panel may not be uniform, and stains cannot be effectively removed. Therefore, we designed a cultural study tour route explanation curtain wall to provide another technical solution to the above technical problems. Utility Model Content

[0017] This utility model provides a cultural study tour route explanation curtain wall. The device improves working efficiency through the design of a moving mechanism, an adjusting mechanism, and a rotating mechanism. The stains on the glass surface of the curtain wall are often unevenly distributed, and traditional one-way wiping is prone to missing some areas. When rotating in both directions, the outer diameter of the wiping point rotates clockwise and the inner diameter rotates counterclockwise, which can make the wiping range cover the entire glass surface and avoid cleaning dead corners. For example, the edges and center areas of the glass can be thoroughly wiped, ensuring that stains in every corner of the glass are removed. Moreover, the friction force generated by the rotation in different directions is different, which can act on the stains from multiple angles. For stubborn stains, one-way wiping may be difficult to remove, but two-way rotation can more effectively decompose and remove stains by changing the direction of friction, thus improving the cleaning effect.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0027] As described in the background art, the cleaning components of the current device rely solely on the pressure of a soft brush for cleaning, which has limited effectiveness against stubborn stains. Furthermore, the distance between the device display panel 4 and the first cleaning disc 27 cannot be adjusted, and the pressure of the first cleaning disc 27 on the display panel 4 may not be uniform, thus failing to effectively remove stains.
[0028] To solve this technical problem, this utility model provides a cultural study tour route explanation curtain wall.
[0029] For details, please refer to Figures 1-6 A cultural study tour route explanation curtain wall specifically includes: a base 1, a first fixing block 2, bolts 3 and a display panel 4. Multiple first fixing blocks 2 are fixed around the base 1, and bolts 3 are slidably connected to the inner side of the multiple first fixing blocks 2. A display panel 4 is fixed on the top of the base 1, and a cleaning structure is provided on one side of the display panel 4.
[0030] This utility model provides a cultural study tour route explanation curtain wall. The device improves working efficiency through the design of a moving mechanism, an adjusting mechanism, and a rotating mechanism. The stains on the glass surface of the curtain wall are often unevenly distributed, and traditional one-way wiping is prone to missing some areas. When rotating in both directions, the outer diameter of the wiping point rotates clockwise and the inner diameter rotates counterclockwise, which can make the wiping range cover the entire glass surface and avoid cleaning dead corners. For example, the edges and center areas of the glass can be thoroughly wiped, ensuring that stains in every corner of the glass are removed. Moreover, the friction force generated by the rotation in different directions is different, which can act on the stains from multiple angles. For stubborn stains, one-way wiping may be difficult to remove, but two-way rotation can more effectively decompose and remove stains by changing the direction of friction, thus improving the cleaning effect.

[0037] The adjustment mechanism includes a second fixed block 14, a third motor 15, a push cam 16, a slide rod 17, a spring 18, and a recess 19. One end of the moving block 13 is fixed to the second fixed block 14, and one end of the second fixed block 14 is fixed to the third motor 15. The output end of the third motor 15 is fixed to the push cam 16. One end of the moving block 13 is slidably connected to the slide rod 17. Springs 18 are sleeved and connected to the outer sides of both slide rods 17. A recess 19 is fixed to one side of both slide rods 17. One side of both springs 18 is fixed to the recess 19, and the other side of both springs 18 is fixed to the moving block 13, so that the adjustment mechanism can adjust the distance between the display plate 4 and the first cleaning plate 27.
[0038] The rotating mechanism includes a fourth motor 20, a first bevel gear 21, a second bevel gear 22, a third bevel gear 23, a rotating column 24, a rotating sleeve 25, a connecting rod 26, a first cleaning disc 27, and a second cleaning disc 28. The fourth motor 20 is fixed to one side of the recess 19, and the first bevel gear 21 is fixed to the output end of the fourth motor 20. The rotating column 24 is rotatably connected to the inner side of one end of the recess 19, and the rotating sleeve 25 is rotatably connected to the inner side of the other end of the recess 19. The rotating sleeve 25 and the rotating column 24 are rotatably connected. Four connecting rods 26 are evenly fixed to the outer side of the rotating sleeve 25. A first cleaning disc 27 is fixed to one side of the four connecting rods 26, and a second cleaning disc 28 is fixed to one side of the rotating column 24.

[0039] A battery is installed on the inside of the base 1, and the first motor 7, the second motor 11, the third motor 15, and the fourth motor 20 are all electrically connected to the battery.
[0040] Adding a self-lubricating material, such as a polytetrafluoroethylene coating, to the contact area between the first slider 6 and the first screw 8 reduces friction, making the sliding smoother and reducing the frequency of maintenance.
[0041] The display panel 4 is equipped with a track to further restrict the movement trajectory of the first T-block 5 and the second T-block 9, thereby improving the stability and accuracy of cleaning.
[0042] The first motor 7, the second motor 11, the third motor 15, and the fourth motor 20 all have the ability to self-lock when power is off, so that the stroke of the device can be locked and controlled.
[0043] This utility model provides a cultural study tour route explanation curtain wall. The device improves working efficiency through the design of a moving mechanism, an adjusting mechanism, and a rotating mechanism. The stains on the glass surface of the curtain wall are often unevenly distributed, and traditional one-way wiping is prone to missing some areas. When rotating in both directions, the outer diameter of the wiping point rotates clockwise and the inner diameter rotates counterclockwise, which can make the wiping range cover the entire glass surface and avoid cleaning dead corners. For example, the edges and center areas of the glass can be thoroughly wiped, ensuring that stains in every corner of the glass are removed. Moreover, the friction force generated by the rotation in different directions is different, which can act on the stains from multiple angles. For stubborn stains, one-way wiping may be difficult to remove, but two-way rotation can more effectively decompose and remove stains by changing the direction of friction, thus improving the cleaning effect.
[0044] The usage process of the cultural study tour route explanation curtain wall provided by this utility model is as follows: When the curtain wall needs to be cleaned, the user energizes the fourth motor 20 to rotate. The rotation of the fourth motor 20 drives the first bevel gear 21 to rotate. Since the first bevel gear 21 is meshed with the second bevel gear 22 and the third bevel gear 23 on one side, the rotation of the first bevel gear 21 drives the second bevel gear 22 and the third bevel gear 23 to rotate in the opposite direction. The rotation of the second bevel gear 22 and the third bevel gear 23 drives the rotating column 24 and the rotating sleeve 25 to rotate in the opposite direction, thereby driving the first cleaning disc 27 and the second cleaning disc 28 to rotate in the opposite direction. At this time, the user energizes the first motor 7 to rotate. The output end of the first motor 7 drives the first screw 8 to rotate. Since the outer side of the first screw 8 is threaded with a moving block 13, the rotation of the first screw 8 drives the moving block 13 to move left and right, so that the first cleaning disc 27 and the second cleaning disc 28 can rotate to clean the curtain wall, completing the cleaning in the left and right directions. Then, the user powers on the second motor 11, which drives the second screw 12 to rotate. Since the outer side of the second screw 12 is also threadedly connected to the moving block 13, the rotation of the second screw 12 causes the moving block 13 to rise and fall. This allows the rotation of the second motor 11 to adjust the cleaning height of the first cleaning disc 27 and the second cleaning disc 28, thus enabling comprehensive cleaning of the curtain wall. If a specific area of the curtain wall needs cleaning, the user powers on the third motor 15, which drives the push cam 16 to rotate. One side of the push cam 16 pushes the slide bar 17 to slide inside the moving block 13, adjusting the distance between the concave block 19 and the moving block 13. This adjusts the distance between the first cleaning disc 27 and the display panel 4, thereby adjusting the wiping force of the first cleaning disc 27 and the second cleaning disc 28 on the curtain wall. Through a series of designs, this utility model effectively overcomes the shortcomings of traditional curtain wall cleaning methods. In practical applications, this cleaning brush significantly improves the adaptability of the cleaning brush to different screen conditions, ensuring the screen always maintains a clear and clean display, greatly enhancing the visitor's visual experience. Simultaneously, it reduces the risk of screen wear caused by improper cleaning, decreasing maintenance frequency and costs, and improving the stability and durability of the interpretive wall. This type of interpretive wall for cultural study tours provides a superior display platform for cultural study activities, powerfully promoting the high-quality development of the cultural study tourism industry, and possesses extremely high practical value and broad market application prospects.
