Description

Technical Field

[0001] This utility model relates to the field of buoyancy cylinder technology, specifically to a buoyancy cylinder for water fireworks. Background Technology

[0002] Water fireworks are a type of fireworks display that uses the interaction of light and shadow between the fireworks and the water to create a unique visual effect. They can be set up directly on the water surface to launch and bloom, or they can use special props to create effects. They are characterized by their distinct features. They not only present a beautiful visual effect of symmetrical fireworks and reflections, adding layers to the picture, but also have greater safety due to the open water area and the ability of the water to cool and extinguish the fire. They also provide a variety of viewing angles, such as from the shore or from boats, allowing the audience to experience their unique charm from different perspectives.

[0003] A search revealed Chinese patent CN201748865U, which discloses a buoyancy cylinder for water-based fireworks. The cylinder includes a fireworks tube body, characterized by a float at the upper end and a counterweight at the lower end. The float is annular and fitted around the outside of the fireworks tube to ensure its balance. This invention utilizes the combination of the float and counterweight attached to the tube body to enable conventionally used cylindrical fireworks tubes to float vertically and stably on water. Its simple structure effectively reduces product size and costs, while also facilitating launch and allowing for easy assembly of multiple units, thus fully achieving the invention's objectives.

[0004] However, the above design still has shortcomings. When placing water fireworks, the lack of effective suspension support mechanisms on both sides of the buoyancy cylinder makes it easy for the water fireworks to tip over during the spraying process, which poses a danger to the personal safety of the surrounding spectators and has low safety.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a buoyancy cylinder for water fireworks to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a buoyancy cylinder for water fireworks, comprising a buoyancy cylinder body, wherein multiple grooves are formed on the outer peripheral wall of the buoyancy cylinder body, multiple adjusting screw holes are uniformly formed on the inner side wall of the grooves, a fixing plate is movably arranged inside the grooves, two fixing holes are formed through the surface of the fixing plate, a fixing hole is threadedly connected to the inner wall of the fixing hole, and one end of the adjusting screw is threaded inside the adjusting screw hole, a connecting rod is fixedly connected to the side of the fixing plate away from the buoyancy cylinder body, and a floating plate is fixedly connected to the bottom of the connecting rod.

[0008] As a further embodiment of this utility model: the number of grooves is four, and the number of adjusting screw holes is not less than seven.

[0009] As a further embodiment of this utility model: a placement base is fixedly connected to the bottom of the buoyancy cylinder body, and a placement groove is opened on the upper surface of the placement base extending into the interior, and the water fireworks body is movably placed inside the placement groove.

[0010] As a further embodiment of this utility model: the upper surface of the buoyancy cylinder body is provided with a plurality of fastening screw holes in a ring array, the number of fastening screw holes being no less than six, and a limit plate is movably provided at the top of the fastening screw holes.

[0011] As a further embodiment of this utility model: a fastening screw is provided through the surface of the limiting plate, and one end of the fastening screw is threaded inside the fastening screw hole.

[0012] As a further embodiment of this utility model: a bottom plate is fixedly connected to the bottom of the buoyancy cylinder body, and the bottom plate is made of fiber-reinforced composite material.

[0013] This utility model has the following beneficial effects:

[0014] (1) Through the structural design of the buoyancy cylinder body, floating plate, connecting rod, fixing plate, fixing hole, adjusting screw, adjusting screw hole and groove, it is possible to facilitate the suspension support of the buoyancy cylinder body, thereby avoiding the overturning of the water fireworks body when it is sprayed, thus better protecting the surrounding spectators and ensuring high safety. At the same time, it is possible to facilitate the adjustment of the position of the floating plate, thereby better meeting the suspension support requirements of different scenarios. This solves the problem in the above design that when the buoyancy cylinder is placed on the water fireworks, the lack of effective suspension support mechanism on both sides makes the water fireworks easy to overturn during the spraying process, thereby endangering the personal safety of the surrounding spectators and resulting in low safety.

[0015] (2) Through the structural design of the water fireworks body, limiting plate, fastening screw, fastening screw hole, placement base and placement groove, the water fireworks body can be placed in the placement groove. After the water fireworks body is placed in the placement groove, the limiting plate can be placed on the upper surface of the water fireworks body, and then the fastening screw can be screwed into the corresponding fastening screw hole to fix the limiting plate. The limiting plate can limit the water fireworks body, thereby improving the stability of the water fireworks body when placed in the placement groove, and thus improving the safety of the water fireworks body when spraying.

The limiting plate 7 can limit the water firework body 6, thereby improving the stability of the water firework body 6 when placed in the placement groove 15, and thus improving the safety of the water firework body 6 when it is sprayed.

[0032] Working Principle: In this application, when the buoyancy cylinder body 1 is placed on the water-based fireworks body 6, the buoyancy cylinder body 1 can be suspended and supported by the cooperation of multiple floating plates 3, thereby preventing the water-based fireworks body 6 from tipping over during spraying. This provides better protection for onlookers and ensures high safety. Furthermore, by adjusting the screw 11 to fit the adjusting screw holes 12 at different positions, the position of the fixing plate 5 within the groove 13 can be adjusted, thereby adjusting the position of the floating plates 3 to better meet the needs of different... In addition to meeting the requirements for suspension support in the same scenario, the water fireworks body 6 can be placed in the placement groove 15. After the water fireworks body 6 is placed in the placement groove 15, the limiting plate 7 can be placed on the upper surface of the water fireworks body 6, and then the fastening screw 8 can be screwed into the corresponding fastening screw hole 9 to fix the limiting plate 7.
