[0031] The present application will be further described in detail below with reference to specific embodiments, but the implementation of the present application is not limited thereto.

[0032] As shown in Figure 1 and Figure 2 The present application provides a reversible popular science guide device, comprising two upright columns 10, two cross beams 20, a support keel 30, a fixed panel 40, a rotating shaft 50 and a plurality of rotating display pieces 60.

[0033] The two cross beams 20 are parallel to each other and located between the two upright columns 10, and the two ends of the cross beam 20 are fixedly connected with the two upright columns 10. One cross beam 20 is located at the top of the upright column 10, and the other cross beam 20 is located at the middle of the upright column 10.

[0034] The support joist 30 is located between the two cross beams 20, and the support joist 30 comprises a rectangular frame 31 and at least two reinforcing ribs 32. The reinforcing ribs 32 are fixedly connected with the rectangular frame 31, and the reinforcing ribs 32 are arranged in a cross manner. The rectangular frame 31 of the support joist 30 is fixedly connected with the two cross beams 20 and the column 10, and the rectangular frame 31 is fixedly connected with the fixed panel 40.

[0035] The rectangular frame 31 of the support joist 30 is fixedly connected with the cross beam 20 through a plurality of angle steel connectors 70 and bolts 80, the rectangular frame 31 of the support joist 30 is fixedly connected with the column 10 through a plurality of angle steel connectors 70 and bolts 80, and the rectangular frame 31 of the support joist 30 is fixedly connected with the edge of the fixed panel 40 through a plurality of angle steel connectors 70 and bolts 80.

[0036] The two ends of the rotating shaft 50 are fixedly connected with the two cross beams 20 respectively, and the rotating shaft 50 is located at one side of the fixed panel 40. The rotating display piece 60 is rotationally connected with the rotating shaft 50. The rotating display piece 60 is a multi-prism structure, and has a plurality of display surfaces. The rotating shaft 50 penetrates through two bottom surfaces of the rotating display piece 60. A plurality of rotating display pieces 60 are arranged in sequence and spaced apart along the axial direction of the rotating shaft 50.

[0037] Preferably, the rectangular frame 31 of the support joist 30 is composed of four square steels, the number of the reinforcing ribs 32 of the support joist 30 is two square steels, the two ends of one reinforcing rib 32 are fixedly connected with two long edges of the rectangular frame 31 respectively, the two ends of the other reinforcing rib 32 are fixedly connected with two short edges of the rectangular frame 31 respectively, and the two reinforcing ribs 32 form a cross structure.

[0038] Preferably, as shown in the drawings, the rotating display piece 60 is a hollow box structure, which is light in weight and easy for the user to manually rotate. Figure 3

[0039] In this embodiment, the multi-surface display can be realized through the rotating display piece 60, and the capacity of information display is increased. Each surface can be used as an independent display area to display different contents. When the user wants to view different popular science contents, the user only needs to manually rotate the rotating display piece 60 to the required angle for viewing. The rotating display piece 60 cooperates with the fixed panel 40 to display information, and a multi-dimensional and multi-functional information display effect is realized. This not only meets the needs of the public for rich popular science contents, but also greatly enhances the interactivity in the popular science process, and improves the user experience. Meanwhile, the support joist 30 can provide stable support and fixation for the fixed panel 40, so that the fixed panel 40 can withstand various external forces in an outdoor environment without being easily deformed, and the connection between the fixed panel 40 and the column 10 is more firm and reliable, which can effectively resist the influence of wind load, vibration and other external forces.

[0040] ​Further, the column 10 and the crossbeam 20 are made of a new type of bamboo-wood fiber composite material, which has excellent performance indicators. Its bending strength ≥ 35 MPa, which means that it can withstand a large external force without bending deformation. For example, in the event of strong winds, ordinary columns 10 may be significantly bent, or even broken, while the new type of bamboo-wood fiber composite material column 10, with its high bending strength, can still maintain a stable upright state. At the same time, its water absorption rate < 0.5%, this feature makes the column 10 in the humid outdoor environment, can effectively avoid the problem of decay, swelling and other problems caused by water absorption. Like in areas with more rain, traditional wooden columns 10 are prone to rot due to long-term water absorption, affecting the normal use of the guide device, while the new type of bamboo-wood fiber composite material column 10 is less likely to occur in such cases.

[0041] Preferably, the cross-sectional size of the column 10 is 150*150mm, and the height is 2m. Such size design not only ensures the stability of the column 10, but also ensures the visual effect of the guide board as a whole and the convenience of information display. In actual installation, the column 10 is directly embedded in the ground, with a depth ≥ 1200mm. This embedding method can firmly fix the column 10 on the ground, providing stable support for the entire guide board.

[0042] The crossbeam 20 is connected with the column 10 through a 4mm thick L40 angle steel connector 70 and a bolt 80. Moreover, the new type of bamboo-wood fiber composite material does not need to be surface treated for corrosion prevention, because the bamboo fiber and epoxy resin inside it form a special structure during the compounding process, which makes it have a natural corrosion resistance. In addition, the material's ultraviolet resistance and weather resistance is more than 10 years, even if exposed to sunlight for a long time, it can still maintain good performance after experiencing wind and rain, severe cold and heat, and other harsh weather conditions, greatly reducing the later maintenance cost.

[0043] Preferably, the rotating display 60 is made of a 2mm thick galvanized steel plate, with a specification of 200*200*200mm cubic shape. The cubic shape can realize multi-face display, greatly increasing the capacity of information display. Each face can be used as an independent display area to display different popular science content.

[0044] The surface is sprayed with anti-ultraviolet outdoor special ink. The ultraviolet radiation in outdoor environment is strong. Ordinary ink is easy to fade and discolor under long-term irradiation of ultraviolet light, resulting in unclear display content. The anti-ultraviolet outdoor special ink has excellent light resistance and can effectively resist the erosion of ultraviolet light, ensuring that the science popularization patterns and texts sprayed on the rotating display piece 60 are always clear and bright. The content can cover a variety of park science popularization themes, such as plant atlas, which can show the morphological characteristics and growth habits of various plants in the park in detail; ecological chain analysis can help visitors understand the relationship between various organisms in the park ecosystem; environmental protection knowledge can spread environmental protection concepts and practical environmental protection methods to the public and improve the public's environmental protection awareness.

[0045] Preferably, the fixed panel 40 is also made of 2mm thick galvanized steel plate. Its main function is to display some relatively fixed information, such as park map, to facilitate visitors to quickly understand the overall layout of the park and the location of each scenic spot; matters needing attention, reminding visitors of the rules and safety matters needing attention in the tour process.

[0046] A 3mm thick 50*30mm square steel support joist 30 is installed on the back of the fixed panel 40, and the square steel support joist 306 is firmly connected with the fixed panel 40. This connection mode ensures that the support joist 30 can provide stable support for the fixed panel 40, so that it can withstand various external forces in outdoor environment without deformation. At the same time, the fixed panel 40 is connected with the support joist 30 through the 4mm thick L40 angle steel connecting piece 70 and the bolt 80, and the support joist 30 is connected with the column 10 and the beam 20 through the L40 angle steel connecting piece 70 and the bolt 80, further enhancing the stability of the whole structure. The L40 angle steel connecting piece 70 can make the connection between the fixed panel 40 and the column 10 more firm and reliable, and can effectively resist the influence of external forces such as wind load and vibration.

[0047] Preferably, the rotating shaft 50 adopts 316 stainless steel shaft with a diameter of φ20mm. The 316 stainless steel material has excellent corrosion resistance and high strength, which can maintain good performance for a long time in humid and corrosive outdoor environment and is not easy to rust. The rotating shaft 50 penetrates the center of the rotating display piece 60, which is the key to ensure the smooth rotation of the rotating display piece 60. The connection part between the rotating shaft 50 and the rotating display piece 60 is finely processed and treated to ensure the flexibility and stability of rotation. For example, there is no jamming and shaking during rotation, so that visitors can easily manually rotate the display piece 60 to switch the display content.

[0048] The working principle of the flipable science popularization guide device is simple and easy to understand and convenient to operate. When the tourists want to view different popular science content, they only need to manually rotate the rotating display piece 60 and rotate it to the target angle according to their own needs. The rotating display piece 60 is clamped into the positioning recess by the pre-set positioning protrusion, thereby being fixed in position and preventing it from being flipped at will. In this way, the tourists can read the popular science information displayed on the current panel at ease. Continue to rotate the rotating display piece 60, and the positioning protrusion slides out of the positioning recess to continue to rotate. The positioning protrusion and the positioning recess are respectively arranged on the rotating shaft 50 and the rotating display piece 60. The fixed panel 40 always displays fixed information, such as a park map and precautions, etc. These information provides the tourists with basic tour guidance and safety tips, and the tourists can obtain these important information at any time regardless of the state of the rotating display piece 60.

[0049] For the administrator, it is also very convenient to update the content of the guide board. When the popular science content needs to be updated, the administrator can choose to replace the entire panel or use the respraying surface. The replacement time of a single panel is less than 10 minutes, which greatly improves the efficiency of information updating. Moreover, the fixed panel 40 also supports a magnetic covering film, and the administrator does not need to disassemble the panel. He only needs to directly adsorb the magnetic covering film with new content on the panel to complete the quick update of the content, further saving time and labor cost.

[0050] In the embodiment, the ingenious combination of the rotating display piece 60 and the fixed panel 40 realizes the perfect complement of dynamic and static information. The rich and varied popular science content on the rotating display piece 60, such as dynamic display of the growth cycle of plants and simulation of biological interaction in the ecological chain, can attract the attention of tourists and stimulate their curiosity and desire to explore. The static information such as the park map and precautions on the fixed panel 40 provides stable and readily available basic service information for tourists. This dynamic and static combination of display mode makes the guide board meet the diverse needs of different tourists at different stages of the tour, greatly improving the effect of information display and the quality of popular science.

[0051] In order to prolong the service life, the traditional wooden column 10 or metal column 10 needs to be regularly treated for corrosion, such as painting and applying anticorrosive agent, etc. This not only needs to consume a lot of manpower, material resources and time, but also may cause certain pollution to the environment. The column 10 and the cross beam 20 of the bamboo-wood fiber composite material, by virtue of their own material properties, do not need any corrosion treatment and can maintain good performance in outdoor environment for more than 10 years of ultraviolet resistance and weather resistance, greatly reducing the maintenance cost and frequency.

[0052] At the same time, the galvanized layer of the galvanized steel panel has a service life of 15 years and excellent corrosion resistance. During long-term outdoor use, the galvanized layer can effectively protect the steel panel from oxidation and corrosion, ensuring that the panel always maintains good appearance and function. This zero-maintenance feature allows the guide board to be used for a long time without frequent maintenance and replacement of parts, reducing operating costs and improving efficiency.

[0053] The multi-faceted rotating display 60 design greatly stimulates children's exploration interest, especially suitable for park parent-child science popularization scenes. During the parent-child tour, children can rotate the display 60 by hand and explore the science popularization content on different surfaces. This interactive experience allows children to actively learn scientific knowledge while playing. For example, when displaying animal science popularization content, children can understand the different living habits and eating habits of animals by rotating the display 60, increasing the interest and participation of learning. Moreover, parents and children can interact and communicate around the content on the rotating display 60, improving the parent-child relationship and the effectiveness of science popularization education.

[0054] The bamboo-wood fiber composite material has natural texture and unique texture, which can perfectly coordinate with the natural environment. In outdoor scenes such as parks and natural education bases, the bamboo-wood texture of the device will not look conspicuous, but can blend into the surrounding natural landscape, enhancing the overall landscape beauty of the park. For example, in a forest-themed park, the bamboo-wood material of the guide device resonates with the surrounding trees, creating a harmonious and unified natural atmosphere. This ecological integration design concept not only makes the guide board a tool for conveying science popularization knowledge, but also a part of the landscape, providing a more enjoyable tour experience for tourists.

[0055] The fixed panel 40 supports the design of the magnetic covering film, making content updating extremely convenient. When updating science popularization information, administrators do not need to use complex tools to disassemble the panel, but only need to directly attract the magnetic covering film with new content to the panel to complete the content update. This method not only saves a lot of time and labor cost, but also ensures timely updating of information, so that the guide board always displays the latest and most accurate science popularization content. For example, when the park holds special activities or needs to promote new science popularization knowledge, administrators can quickly replace the magnetic covering film to enable tourists to obtain relevant information in the first time. Moreover, the replacement process of the magnetic covering film is simple and easy to understand, even non-professionals can easily operate, improving the efficiency and flexibility of information updating.

[0056] The installation method of the utility model is:

[0057] Column 10 installation: When installing the column 10 in the park scene, it is necessary to strictly follow the specifications. First, choose a suitable position next to the park trail and dig a hole with a depth of ≥1200mm. This depth is set to ensure that the column 10 can be firmly fixed to the ground and resist various external forces. After digging, carefully place the column 10 into the pit, adjust the verticality and position of the column 10 to ensure it is upright and coordinated with the surrounding environment. Then, fill the pit with concrete or other suitable filling materials to tightly combine the column 10 with the ground. During the filling process, pay attention to vibration compaction to ensure that the filling material can fully wrap the column 10 and improve the stability of the column 10. After filling, let the concrete naturally cure for a period of time, and then perform subsequent installation work after it reaches a certain strength. During the curing period, pay attention to protecting the column 10 to avoid being damaged by external forces.

[0058] Panel assembly:

[0059] Rotary display 60: A 2mm thick galvanized steel plate is processed into a 200*200*200mm cubic rotary display 60. This processing process requires precise measurement and cutting technology to ensure the size accuracy and shape of the panel. After processing, the rotary display 60 is installed on the support through a φ20mm stainless steel rotating shaft 50. During installation, ensure that the rotating shaft 50 is firmly and reliably connected to the rotary display 60, and the rotation is smooth. A suitable amount of lubricating oil can be applied at the connection between the rotating shaft 50 and the rotary display 60 to reduce friction resistance and improve the flexibility of rotation.

[0060] The four sides of the rotary display 60 respectively introduce popular science content through illustrations and texts. When designing the illustrations and texts, the reading habits and cognitive level of tourists should be fully considered, and simple and clear words and vivid images should be combined. For example, when introducing plant popular science content, high-definition pictures of plants can be provided, with information such as plant name, characteristics, and growth environment marked, so that tourists can understand at a glance. When spraying popular science content on the surface of the rotary display 60, high-quality anti-ultraviolet outdoor special ink should be used to ensure that the pattern is clear and the color is bright. During the spraying process, the thickness and uniformity of the ink should be strictly controlled to avoid color difference and blurring.
