The top of the box body 10 is provided with an opening 11 communicating with its internal cavity. A projection assembly 20 is installed on the top of the box body 10. The projection assembly 20 includes a projection cover 21. The projection cover 21 is sleeved above the opening 11. The top of the box body 10 is provided with a discharge port 13 located outside the projection cover 21. The side wall of the box body 10 is plugged with a loading frame 30 slidably connected to the loading frame 30. The side wall of the loading frame 30 is provided with a side plate 31 locked with the box body 10; a vertically arranged conveyor belt 33 is fixed in the loading frame 30 through a pillar 32 A mounting frame 40 mounted on the pillar 32 is provided on the side of the conveyor belt 33 close to the side plate 31, a slide plate 50 is slidably connected to the top of the mounting frame 40, a pull rod 52 is fixed to the side wall of the end of the slide plate 50 away from the drying box 51, and the end of the pull rod 52 away from the slide plate 50 passes through the side plate 31, a drying box 51 located below the projection cover 21 is embedded on the top of the slide plate 50, and the drying box 51 is filled with desiccant, a chute 53 located on one side of the heating plate 54 is provided on the top of the mounting frame 40, and a terminal adapted to the heating plate 54 is slidably connected in the chute 53, and the terminal and the heating plate The slide plate 50 is provided with a heating plate 54 embedded in the top of the mounting frame 40 at the bottom of the other end of the slide plate 50. The heating plate 54 is located directly below the discharge port 13. The inner wall of the opening 11 close to the discharge port 13 is provided with a feed port 12 located below the projection cover 21. The distance between the feed port 12 and the discharge port 13 is the same as the distance between the bottom of the end of the slide plate 50 away from the drying box 51 and the heating plate 54. There are four pillars 32. The tops and bottoms of the two pillars 32 located in the same vertical plane are both provided with rotating rollers. The four rotating rollers are connected by a conveyor belt 33. The conveyor belt 33 is in a U-shaped structure, a driving motor 41 is installed on the mounting frame 40, and the output end of the driving motor 41 is connected to a rotating rod 43 for driving the rotating roller to rotate through a belt 42. A distribution box 44 is installed on the mounting frame 40. The projection assembly 20 also includes an imaging device located on the top of the projection cover 21. A control panel is installed on the side wall of the side panel 31. The control panel and the projection assembly 20 are electrically connected through a metal bellows with a spiral connecting line inside. The loading frame 30, the box body 10, and the side walls of the side panel 31 are all provided with fasteners for fixing the metal bellows.

[0033] Working principle: The projection assembly 20 forms an image in the projection cover 21, and plays pre-made videos and text introductions for tourists to watch and learn. The slide plate 50 is provided with a drying box 51 at one end which is located directly below the feed port 12. The desiccant in the drying box 51 dehumidifies the projection cover 21. The desiccant is preferably anhydrous copper sulfate. When the desiccant absorbs water, it changes from white to blue. The pull rod 52 is pulled, and the slide plate 50 slides on the top of the installation frame 40. The drying box 51 moves to directly above the heating plate 54. The terminal and the heating plate 54 form a closed loop to remove the hydrated water of the anhydrous copper sulfate. In this process, the slide plate 50 abuts against the bottom of the discharge port 13, and the side plate 31 is locked with the box body 10 to ensure the airtightness between the box body 10 and the projection cover 21.

[0034] It should be noted here that the pull rod 52 can also be a common device such as an electric push rod. The public documents of application numbers CN2015208155123 and CN202110130784X have explained the working principle of the projection assembly 20, which will not be repeated here.

[0035] Embodiment 2:

[0036] Reference Figure 1-5 A three-dimensional projection display device for a hall is the same as the first embodiment. The difference between this embodiment and the first embodiment is that a plurality of partitions 34 are installed on the side walls of the conveyor belt 33, and the plurality of partitions 34 divide the top of the conveyor belt 33 into a plurality of display spaces. Display components installed in the display space are fixed on the top of the conveyor belt 33. The display space on the conveyor belt 33 is an empty space, and the partitions 34 on both sides of the empty space are located below the opening 11.

[0037] Working principle: Since the imaging accuracy of existing stereoscopic projection devices is not high, the display component can be a specific form or a characteristic appearance of a marine organism. The color and other features can be projected on the display component through the projection device, which can more vividly visualize the distinguishing features of the marine organism, which is convenient for display and learning. The partitions 34 on both sides of the vacant space are arranged below the opening 11, which is convenient for removing the object frame 30, the support 32 and the conveyor belt 33 from the box 10, and is convenient for device maintenance and replacement of internal display components. When the display component on the display space is located at the opening 11, the partition 34 is also located in the opening 11. When the display component falls off, it is blocked to prevent damage to other display components.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
