Detailed implementation manners

[0021] The following further Figures 1-3 describes the present application in detail with reference to the

[0022] An embodiment of the present application discloses a multi-functional intelligent exhibition hall for a construction site. As Figure 1 shown, it includes a display platform 1, on which there are a sand table model 11, several information display films 2 and a switching structure. The information film is made of flexible transparent material, and different types of information are marked on different information display films 2; the sand table model 11 is located in the sunken space in the middle of the display platform 1, and the sand table model 11 is a small three-dimensional model that restores the actual terrain of the construction site. The switching structure is used to selectively cover the information display film 2 on the surface of the sand table model 11. After the information display film 2 covers the sand table model 11, the corresponding specific information thereon can be displayed in the three-dimensional form of the sand table model 11.

[0023] As Figure 1 and 2As shown, the switching mechanism 3 includes a storage roller 34 and a moving frame 31. The moving frame 31 moves relative to the display stand 1 in the vertical direction. The number of storage rollers 34 is the same as the number of information display films 2. The storage rollers 34 are rotatably arranged on the moving frame 31 in the horizontal direction. A single information display film 2 is wound around one storage roller 34, and the arrangement direction of the multiple storage rollers 34 is the vertical direction. One side edge of the information display film 2 is connected to the moving frame 31, and the other side edge is fixedly connected to the side wall of the storage roller 34. The axis of the storage roller 34 is also in the horizontal direction. During the rolling of the storage roller 34, it accordingly stores or unwinds the information display film 2 connected thereto. The unwound information display film 2 is horizontally spread above the sand table model 11. An electric slider 33 is slidably arranged on the moving frame 31. The sliding direction of the electric slider 33 is the horizontal direction and is perpendicular to the axis of the storage roller 34. The storage roller 34 is rotatably connected to the electric slider 33; a matching gear 341 is coaxially and fixedly connected to the storage roller 34, and a matching rack 311 is fixedly connected to the moving frame 31 along the sliding direction of the electric slider 33. The matching gear 341 and the matching rack 311 are meshed with each other. When the electric slider 33 moves in the horizontal direction, under the action of the serrated meshing, the matching gear 341 and the storage roller 34 rotate synchronously to realize the winding or unwinding of the information display film 2.

[0024] As Figure 2 and 3 shown, in this embodiment, the cross-sectional circumference of the storage roller 34 is the same as the pitch circle circumference of the matching gear 341, that is, the length of the information display film 2 tightly wound around the surface of the storage roller 34 and released as the storage roller 34 rolls is basically equal to the distance the storage roller 34 rolls; and when the information display film 2 is wound around the storage roller 34 for multiple turns, the length of the information display film 2 released when the storage roller 34 rotates one week is greater than the distance the storage roller 34 moves. Therefore, a self-adjusting rod 32 is slidably arranged on the moving frame 31. The length direction of the self-adjusting rod 32 is parallel to the axis of the storage roller 34, and the sliding direction is parallel to the sliding direction of the electric slider 33. One side edge of the information display film 2 away from the storage roller 34 is fixedly connected to the self-adjusting rod 32. A flexible cord 321 made of silica gel is connected between the self-adjusting rod 32 and the moving frame 31. The telescopic direction of the flexible cord 321 is parallel to the moving direction of the self-adjusting rod 32. During the process of the storage roller 34 rolling to wind and unwind the information display film 2, due to the difference between the winding and unwinding length of the information display film 2 and the distance the storage roller 34 rolls, the self-adjusting rod 32 is forced to move, and the flexible cord 321 always makes the self-adjusting rod 32 have a tensioning force on the information display film 2, and this tensioning force is small enough not to cause serious wrinkles to the information display film 2 due to excessive tension.

[0025] As Figures 1-3As shown in the figure, a cylinder (not shown in the figure) for driving the movable frame 31 to move up and down is provided inside the display stand 1. After the information display film 2 is unfolded, the lifting frame moves downward so that the information display film 2 fits the sand table model 11. The marked information on the information display film 2 corresponds to the surface of the sand table model 11. In order to improve the relative position accuracy between the two, a plurality of positioning iron sheets 22 are fixedly connected to the information display film 2, and a plurality of positioning magnetic blocks 12 are fixedly connected to the sand table model 11. The positioning magnetic blocks 12 are mainly arranged at the edges, bump positions, and concave positions on the sand table model 11, etc. When the information display film 2 fits on the surface of the sand table model 11, the positioning iron sheets 22 should fit and adsorb with the positioning magnetic blocks 12 one by one. A negative pressure air pump (not shown in the figure) is provided inside the display stand 1. An adsorption hole 111 is opened on the sand table model 11. The orifice of the adsorption hole 111 is located on the side of the sand table model 11 facing the information display film 2. The adsorption hole 111 is communicated with the negative pressure air pump. After the positioning magnetic block 12 and the positioning iron sheet 22 are mutually attached, the negative pressure air pump is started. Under the action of negative pressure, the information display film 2 and the surface of the sand table model 11 have a higher degree of fitting. The positioning magnetic block 12 is an electromagnet, that is, the adsorption effect of the positioning magnetic block 12 on the positioning iron sheet 22 needs to be energized to start. When the movable frame 31 has not descended to the end position, the positioning magnetic block 12 is not energized temporarily to reduce the magnetic force influence of the positioning magnetic block 12 on the non-corresponding positioning iron sheet 22. When the information display film 2 has descended in place, the operator can adjust the deviation of the information display film 2 according to the situation, and then energize the positioning magnetic block 12, and the two can be mutually adsorbed and fixed. Subsequently, the negative pressure air pump is started, and the fixing relationship between the two is further strengthened.

[0026] As Figures 1-3As shown in the figure, in order to improve the stability of the edge part of the information display film 2 when it is under negative pressure and the airtightness between it and the sand table model 11, a sealing rubber strip 21 is fixedly connected to the edge of the information display film 2. A compaction fixture 4 is provided on the display table 1. After the information display film 2 covers the surface of the sand table model 11, the sealing rubber strip 21 forms a rectangular encirclement around the sand table model 11. The compaction fixture 4 is used to press the sealing rubber strip 21. The compaction fixture 4 includes a flipping block 41 and a driving assembly 42. The flipping block 41 is movably connected to the display table 1, and the driving assembly 42 is used to control the movement of the flipping block 41. A single edge of the sand table model 11 corresponds to a flipping block 41. For a single flipping block 41, its corresponding driving assembly 42 includes two driving rods 421 and a driving source. One end of the driving rod 421 is hinged to the display table 1, and the other end is hinged to the flipping block 41. The length directions of the two driving rods 421 are parallel and their lengths are equal. Based on the display table 1, the two driving rods 421 and the flipping block 41 form a parallelogram linkage mechanism. The swinging of the driving rod 421 can make the flipping block 41 move closer to or away from the sand table model 11, and the movement trajectory is an arc. When the information display film 2 covers the sand table model 11, the flipping block 41 is moved closer to the sand table model 11, and the flipping block 41 can abut against the edge of the information display film 2. The opposite sides of the sealing rubber strip 21 respectively abut against the flipping block 41 and the sand table model 11, so as to form a sealed space between the information display film 2 and the sand table model 11. During operation, the pressing action of the flipping block 41 should be before the negative pressure air pump is turned on. The driving source is used to control the rotation of one of the two driving rods 421. In this embodiment, the driving source is a motor (not shown in the figure), and the output shaft of the motor is coaxially fixedly connected to the rotation shaft of one of the driving rods 421 and the display table 1.

[0027] The implementation principle of a multi-functional intelligent exhibition hall for construction sites in an embodiment of the present application is as follows: During the use of this application, the quantity and types of the information display film 2 are determined according to actual display requirements, and the switching process of the information display film 2 should be carried out strictly in accordance with the operation sequence. It should be noted that: First, since the information display film 2 vertically covers the sand table model 11, the edge of the sand table model 11 is flat but has a three-dimensional structure with different heights in the middle. Accordingly, the surface area within the unit width in the middle of the information display film 2 is larger than that of the edge part, so as to improve the fitting property between the two. Second, the coverage of the information display film 2 can better adapt to the relatively gentle undulating terrain on the sand table model 11, but for the obvious protrusions such as building modules with sharp corners, the fitting situation is poor. Therefore, through holes for the protruding modules to pass through can be opened at the corresponding positions of the information display film 2 to improve the adaptability of the information display film 2. Third, the positioning iron sheet 22 and the positioning magnetic attraction block 12 are arranged to enable the information display film 2 and the sand table model 11 to have a relatively stable and easily adjustable state before the negative pressure air pump is started. Therefore, the adsorption force does not need to be very large, and the positioning iron sheet 22 should be small and thin, and at the same time, its own influence on information display is also reduced.

[0028] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
