[0002] The three-view drawing of water conservancy project facilities is characterized by complex structure and many details, and it is not easy for observers to obtain information about the water conservancy facilities intuitively. In order to display the structure and characteristics of the water conservancy model more quickly and intuitively, a three-dimensional model display form is used to show the project's external dimensions and other information.

It is inevitable that the equipment will be bumped during transportation back and forth and when not on display, causing the display model to fall, which can easily cause impact and loss. In addition, the existing display equipment has a fixed structure. If viewers want to fully observe the appearance of the model, they need to walk along the display equipment, which is very inconvenient. Utility Model Content

Both ends of the eccentric rod 24 are hinged with shift blocks 25, and the shift blocks 25 are respectively slidably connected to the swing rod 21 and the limit folding rod 23. One of the pair of shift blocks 25 is located at the upper part of the eccentric rod 24, and the other is located at the lower part of the eccentric rod 24. The output end of the second motor 22 is not connected to the center of the eccentric rod 24. The protrusion ring 2 is annular and has a plurality of protrusions on the lower part, and grooves are formed between the protrusions. The output end of the second motor 22 passes through the limit folding rod 23.

[0029] In the specific implementation process, Figure 3 and Figure 4As shown, when the water conservancy model is displayed, the second motor 22 is started, and the eccentric rod 24 of the second motor 22 performs an oscillating motion under the action of the eccentric shaft, and the eccentric rod 24 drives the shift block 25 to perform an oscillating motion, and the shift block 25 drives the swing rod 21 to swing, and the shift block 25 is inserted into the groove of the protrusion ring 2 through the swinging, so that the shift block 25 drives the protrusion ring 2 to rotate intermittently through the groove on the protrusion ring 2, and the protrusion ring 2 drives the water conservancy module on the placement plate 115 to rotate intermittently and slowly, so that the water conservancy model can be displayed in an all-round three-dimensional manner, and through the coordinated use of the protrusion ring 2, the swing rod 21, the second motor 22, the limit folding rod 23, the eccentric rod 24 and the shift block 25, when the model is displayed, it can be made to rotate intermittently, and the viewers only need to stay in one place to slowly observe the overall appearance of the model.

[0030] Specifically, the working principle and operation method of the utility model are as follows:

[0031] Step 1, put the hydraulic model on the placement plate 115, cover it with a transparent protective cover 116, start the first motor 11 at the end of the display, the first motor 11 drives the first gear 12 to rotate, the first gear 12 drives the round cross bar 13 to rotate through the second gear 14, the round cross bar 13 drives the worm 15 to rotate, the worm 15 drives the threaded rod 16 to rotate through the worm gear 17, the threaded rod 16 drives the hydraulic model and the transparent protective cover 116 on the placement plate 115 to descend through the lifting plate 18, so that the transparent protective cover 116 descends into the protection box 1 for protection, pushes the vertical plate 114, and the vertical plate 114 drives the cover plate 112 to move out of the slide slot 111, when the cover plate 112 meets in the middle, the magnet 113 attracts each other with opposite poles, and the top of the protection box 1 covers the hydraulic model for protection, and when displaying, pull the vertical plate 114 to both sides, lift the placement plate 115, and then it can be displayed again;

[0032] Step 2: When the hydraulic model is displayed, the second motor 22 is started. The eccentric rod 24 of the second motor 22 performs an oscillating motion under the action of the eccentric shaft. The eccentric rod 24 drives the shift block 25 to perform an oscillating motion. The shift block 25 drives the swing rod 21 to swing. The shift block 25 is inserted into the groove of the protrusion ring 2 through the swing. The shift block 25 drives the protrusion ring 2 to rotate intermittently through the groove on the protrusion ring 2. The protrusion ring 2 drives the hydraulic module on the placement plate 115 to rotate intermittently and slowly, so that the hydraulic model can be displayed in an all-round three-dimensional manner.
