[0055] To more clearly demonstrate the technical solution and its effects provided by this utility model, the following detailed description of the solution provided by the embodiments of this utility model is provided with reference to specific examples.

[0056] Example 1

[0057] like Figures 1 to 3 As shown, this utility model embodiment provides a simulated sinking performance device, mainly comprising:

[0058] Several ship-related simulated modeling components, fan assembly 11, truss assembly 12, suspension rope drive assembly 13, control assembly 14, gauze screen 15, projector assembly 16, and effect lighting assembly 17; among which,

[0059] The simulated ship components are mainly common ship materials, such as several humanoid components, several floating ship simulation components, and several sunken ship simulation components.

[0060] Among them, there are several humanoid components 1, each with a different shape. All clothing and hair of each humanoid component 1 must be processed to simulate the weightlessness effect underwater, which can simulate the effect of a corpse floating underwater.

[0061] Each humanoid component 1 is made of lightweight foam and composite materials, with a lightweight metal frame embedded inside and hanging points set. To maintain stable lifting, there are multiple hanging points, and the traction rope 131 in the suspension rope drive component 13 is used to suspend it below the truss component 12.

[0062] The aforementioned floating ship simulation components mainly include anchor 2, rudder 3, rapid-fire gun 4, searchlight 5, wooden box assembly 7, lifeboat 8, etc. These floating ship simulation components are all made of lightweight foam and composite materials. They are all pre-embedded with lightweight metal frames and have hanging points. They are suspended below the truss assembly 12 by the traction rope 131 in the suspension rope drive assembly 13. This can simulate the effect of the ship's components sinking and floating underwater after damage. The traction rope 131 in the suspension rope drive assembly 13 is used to suspend the components below the truss assembly 12.

[0063] The aforementioned anchor 2, rudder 3, rapid-fire gun 4, searchlight 5, and lifeboat 8 are all made of lightweight foam material, with simulated effects on the surface. They have a light metal frame embedded inside and multiple hanging points to maintain stable lifting and lowering. They are hung and fixed using the corresponding traction rope 131 in the rope drive assembly 13.

[0064] The aforementioned wooden box components 7 are numerous, made of lightweight foam material, with a simulated surface, an internal lightweight metal frame, and multiple hanging points to maintain stable lifting. They are suspended and fixed using the traction rope 131 in the suspension rope drive component 13.

[0065] The aforementioned flag 6 is also a component of the floating ship simulation model. It is made of flag fabric and has a shaping and hanging frame. It is suspended below the truss assembly 12 using the traction rope 131 of the suspension rope drive assembly 13. Preferably, the surface of the flag 6 has a simulated aging effect and can be set into various shapes and patterns of flags as needed, such as dragon flags. To maintain stable lifting and lowering, multiple hanging points are set on the hanging frame.

[0066] The aforementioned simulated components of sunken ships mainly include mast 9 and ship cabin iron plate 10. They are all simulated shapes made of lightweight materials. The mast 9 is fixed at its inclined bottom to the ground below the truss assembly 12. The ship cabin iron plate 10 is suspended below the truss assembly 12 by a towing rope 131, which can better simulate and create the seabed environment of the sunken ship.

[0067] Preferably, the surface of the mast 9 is made to resemble a simulated surface, and multiple hanging points are set on the internal pre-embedded light metal frame to maintain stable lifting and lowering. The bottom is fixed to the ground with expansion bolts.

[0068] The surface of the aforementioned ship cabin iron plate 10 is also simulated, and the internal pre-embedded light metal frame is also equipped with multiple hanging points to maintain stable lifting and lowering.

[0069] The aforementioned fan assembly 11 is screwed onto the truss assembly 12 and vertically aligned with the hanging position of the flag 6 to simulate the effect of the flag 6 fluttering in the water. Preferably, the fan assembly 11 uses a silent fan with adjustable wind speed. Screwed onto the truss assembly 12 and aligned vertically with the flag 6, it can blow air onto the flag 6 to better simulate the effect of the flag floating underwater with the current. It can be understood that as long as the fan assembly 11 can blow air onto the flag 6 to better simulate the effect of the flag floating underwater with the current, the installation position of the fan assembly 11 on the truss assembly 12 is not specifically limited. Installation at the top, bottom, or side, etc., can achieve various performance effects within the scope of this utility model.

[0070] The aforementioned truss assembly 12 is installed on the building's top structure and is used to install and fix all performance props and equipment.

[0071] The aforementioned suspension rope drive assembly 13 is installed at the tail of the truss assembly 12, and the lifting and lowering performance props are suspended using the traction rope 131 in the suspension rope drive assembly 13.

[0072] The aforementioned translucent gauze screen 15 is vertically installed on the ground in front of the truss assembly 12, and must completely cover the width and height range of the truss assembly 12, while also meeting the light transmission requirements of the projector. Preferably, the translucent gauze screen 15 is a transparent, light-transmitting, and projection-type gauze screen, complete without splicing, and its overall installation dimensions should be greater than the installation width and height of the truss assembly 12. The surrounding installation area and some areas of the translucent gauze screen 15 are decorated and concealed.

[0073] The aforementioned projector assembly 16 is installed in the top area directly in front of the gauze screen 15, projecting water ripples, bubbles, and light and shadow onto the translucent gauze screen 15 to achieve a more realistic underwater effect through a combination of virtual and real elements. Preferably, the projector assembly 16 uses a high-quality, high-definition projection device to project onto the translucent gauze screen 15. The projection size, resolution, and other parameters are adjustable, and all high-quality projection devices meet the practical requirements of this invention. It can be understood that the projector assembly can use one or more high-resolution projectors. When multiple projectors are combined, image stitching technology is used to achieve large-screen projection. All devices capable of meeting the projection effect requirements are within the scope of practical application of this invention.

[0074] The aforementioned effect light components 17 are installed on the left and right sides of the truss component 12, and can project light to simulate the light effect in water. Specifically, the effect light components 17 are installed on the left and right sides of the truss component 12 using their own fixing parts, and are used to simulate the light atmosphere effect of the suspended shape below the truss 12 floating in the water. All effect light components are RGB lamps and can realize DMX512 multi-channel control. It can be seen that any lamp that can simulate the dim light effect underwater can be used, including but not limited to LED lamps, PAR lamps, spotlights, water ripple lamps and other lamps with different effects. All devices that meet the lighting effect are within the scope of practical application of this invention.

[0075] The aforementioned control component 14 is installed at the tail of the truss assembly 12 and is used to control the suspension rope drive assembly 13, the projector assembly 16, and the effect light assembly 17, so that the lifting performance props connected to the suspension rope drive assembly 13 can perform synchronously with the projector assembly 16 and the effect light assembly 17. Preferably, the control component 14 integrates PLC controllers, lighting control components, and other related electronic components, and can realize centralized control of the start and stop triggering and performance duration of the fan assembly 11, suspension rope drive assembly 13, projector assembly 16, and effect light assembly 17. It can be controlled by trigger signals or set to manual control.

[0076] The aforementioned truss assembly 12 is a steel structure, installed on the top of the submerged performance device area, and fixed to the building structure by rebar anchoring. It is used to fix the suspension rope drive assembly, control assembly, and effect lighting assembly.

[0077] The aforementioned sling drive assembly 13 is fixed to the truss assembly 12 with screws. The sling drive assembly 13 has multiple built-in traction ropes 131 for suspending various parts of the simulated shipwreck. The power and speed of the sling drive assembly 13 are adjustable, and the installation position of the suspension point is adjustable. The traction ropes 131 are made of high-strength thin rope material.

[0078] It can be seen that, for the sake of performance effects, the humanoid component in the above-mentioned device can also be replaced with a real actor to perform.

[0079] In summary, the simulated sinking performance device of this utility model can be used not only in the field of amusement equipment but also in the field of stage performances. Its structure is compact, and the various components work together seamlessly to achieve a unified and natural performance, projection, and lighting effects. The overall effect is comprehensive, with a strong sense of realism and atmosphere. It can recreate the effect of people and props on the ship sinking and drifting underwater during ground performances, allowing the audience's perspective to enter the seabed along with the sinking of the Zhiyuan ship. In the cold and dark seabed, only a few beams of cool sunlight can be seen, and water ripples and light spots flow. Through the gauze screen, one can see the corpses of people and ship wreckage slowly sinking in the water. The overall scene presents a tragic and somber atmosphere. The overall simulated sinking performance device highly restores the effect of the ship sinking underwater, with a magnificent momentum, a combination of reality and illusion, high scene restoration, good dynamic performance, and a realistic and natural effect.
