Description

Technical Field

[0001] This utility model relates to the field of foamed float technology, and in particular to a biodegradable and environmentally friendly EVA foamed float. Background Technology

[0002] Because its density is less than that of water, it can provide stable buoyancy on the water surface and can be used to support various aquatic facilities or objects. For example, in aquaculture, it supports aquaculture cages so that they can float on the water surface, providing a suitable growth space for aquatic organisms such as fish; in aquatic photovoltaic power generation projects, it supports photovoltaic panels so that they can float stably on the water surface to generate solar energy.

[0003] However, in the existing technology, if there is a lack of special connectors or the existing connectors are not compatible with the floats during the use of foamed floats, it will lead to connection difficulties. If the foamed floats cannot be connected together smoothly, it will not only complicate the construction process, but also increase the workload and difficulty of the construction personnel, thereby prolonging the construction time. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that if it is difficult to connect the foamed floats together, it will complicate the construction process and increase the workload and difficulty of the construction workers. Therefore, a biodegradable and environmentally friendly EVA foamed float is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a biodegradable and environmentally friendly EVA foamed float, comprising a sphere, a first outer ring fitted at the top of the sphere, and a second outer ring fitted at the bottom of the sphere, with fixing plates fixedly connected to both ends of the first outer ring and both ends of the sphere, threaded rods penetrating the surfaces of the two fixing plates, and nuts threadedly connected to the outer surfaces of both ends of the threaded rods, a counterweight fixedly connected to the center of the bottom of the second outer ring, and a hanging ring fixedly connected to the center of the top of the first outer ring.

[0006] Preferably, a polyurethane elastic layer is provided on the outer surface of the sphere.

[0007] Preferably, the inner side of the polyurethane elastic layer is filled with a low-density polyethylene foam layer.

[0008] Preferably, a glass fiber reinforcement layer is compositely connected to the inner side of the low-density polyethylene foam layer.

[0009] Preferably, a butyl rubber layer is compositely bonded to the inner side of the glass fiber reinforced layer.

[0010] Preferably, an EVA and nano-calcium carbonate composite layer is provided on the inner side of the butyl rubber layer.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, a firm connection between the first outer ring and the second outer ring is achieved through a threaded rod and a nut, ensuring that the overall structure remains stable and reliable under stress. The counterweight effectively adjusts the center of gravity of the ball, keeping the hanging ring facing upwards on the water surface, which facilitates quick connection and operation. The overall design combines waterproof, corrosion-resistant and wave-resistant performance, improving the adaptability and safety of the device in complex aquatic environments. At the same time, it is easy to operate and facilitates the execution of positioning, traction and other functions in practical applications.

[0013] 2. In this utility model, the polyurethane elastic layer provides excellent wear-resistant and tear-resistant protection, the low-density polyethylene foam layer effectively absorbs impact and ensures buoyancy, the glass fiber reinforcement layer enhances structural rigidity and compressive strength, the butyl rubber layer ensures good airtightness and watertightness to avoid buoyancy loss, and the EVA and nano-calcium carbonate composite layer further improves hardness, wear resistance and flame retardancy.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1: As Figure 1 As shown, this utility model provides a biodegradable and environmentally friendly EVA foamed float, including a sphere 5, a first outer ring 2 fitted at the top of the sphere 5, and a second outer ring 7 fitted at the bottom of the sphere 5. Fixing plates 3 are fixedly connected to both ends of the first outer ring 2 and both ends of the sphere 5. Threaded rods 4 penetrate the surfaces of the two fixing plates 3. Nuts 8 are threadedly connected to the outer surfaces of both ends of the threaded rods 4. A counterweight block 6 is fixedly connected to the center of the bottom of the second outer ring 7, and a hanging ring 1 is fixedly connected to the center of the top of the first outer ring 2.

[0021] The specific setup and function of this embodiment are described below. When connecting the first outer ring 2 and the second outer ring 7, the two fixing plates 3, respectively located at their ends, are first joined together to ensure a tight fit between their mating surfaces, thus providing a foundation for the subsequent mechanical connection. Subsequently, the threaded rod 4 is passed through the through holes on the two fixing plates 3 in sequence to achieve a mechanical through-connection between the fixing plates 3. After the threaded rod 4 is inserted, nuts 8 are tightened at both ends to ensure that the entire connection structure is subjected to uniform force, effectively preventing loosening or misalignment at the connection point due to external forces, thereby ensuring a firm and stable connection between the first outer ring 2 and the second outer ring 7.

[0022] Furthermore, to enhance the stability and functionality of the sphere 5 on the water surface, a counterweight 6 is installed at the bottom of the second outer ring 7. This counterweight 6 has a moderate mass and can adjust the center of gravity of the sphere 5 without affecting its overall buoyancy, ensuring that the hanging ring 1 always faces upwards when the sphere 5 is floating. The advantage of this structural design is that it ensures that the hanging ring 1 is always in an easily accessible position during use, allowing ropes to be easily threaded through it, thus reliably connecting the sphere 5 to other devices or for positioning, traction, and other operations. The overall structure not only possesses excellent waterproof and corrosion-resistant properties but also demonstrates strong stability against wind and waves and ease of operation in practical applications.

[0023] Example 2: Figure 2 and Figure 3 As shown, a polyurethane elastic layer 51 is disposed on the outer surface of the sphere 5. A low-density polyethylene foam layer 52 is filled inside the polyurethane elastic layer 51. A glass fiber reinforcement layer 53 is compositely connected inside the low-density polyethylene foam layer 52. A butyl rubber layer 54 is compositely connected inside the glass fiber reinforcement layer 53. An EVA and nano-calcium carbonate composite layer 55 is disposed inside the butyl rubber layer 54.

[0024] The overall effect of this embodiment is that the polyurethane elastic layer 51, with its unique molecular structure, exhibits excellent wear resistance and tear resistance, effectively resisting scratches and impacts from sharp objects, greatly ensuring the surface strength of the float. Even in complex usage environments, it can significantly extend the service life of the float, while also possessing good weather resistance, adapting to different temperature and humidity conditions, and maintaining stable performance. The low-density polyethylene foam layer 52, with its significant characteristics of being lightweight and having excellent cushioning, acts like countless tiny springs when the float is impacted by external forces, quickly absorbing and dispersing the impact force, effectively reducing the risk of damage to the float caused by collisions. At the same time, its lightweight texture does not excessively increase the overall weight of the float, ensuring that the float maintains good buoyancy. The glass fiber reinforced layer 53 fully... Leveraging its high strength and high modulus, the float's rigidity and pressure resistance are greatly enhanced. Whether subjected to the pressure of heavy objects above or the pushing force of water flow, waves, etc., the float can maintain a stable shape and structure, avoiding deformation and damage. The butyl rubber layer 54, with its excellent airtightness and watertightness, effectively prevents gas and water penetration. On the one hand, it prevents the float's buoyancy from decreasing due to gas leakage, and on the other hand, it prevents water intrusion from affecting the internal structure, providing a reliable guarantee for the long-term stable operation of the float. The EVA and nano-calcium carbonate composite layer 55, through the organic combination of nano-calcium carbonate and EVA, significantly improves the internal hardness and wear resistance of the float, making its internal structure more robust and durable. At the same time, it can also effectively improve the float's flame retardant properties and reduce fire hazards.

[0025] The usage and working principle of this device are as follows: When connecting the first outer ring 2 and the second outer ring 7, first align the two fixing plates 3 together, then pass the threaded rods 4 through the two fixing plates 3 respectively, and tighten the connection with nuts 8 to ensure a stable connection between the first outer ring 2 and the second outer ring 7. The counterweight 6 is installed at the bottom of the second outer ring 7, which can keep the hanging ring 1 above when the ball 5 floats on the water surface, making it easier for the rope to pass through the hanging ring 1 and connect and fix the ball 5.

[0026] The polyurethane elastic layer 51 has excellent wear resistance and tear resistance, which can enhance the strength of the float surface; the low-density polyethylene foam layer 52 is lightweight and has good cushioning performance, which can effectively absorb impact force; the glass fiber reinforced layer 53, with its high strength and high modulus, improves the rigidity and compressive strength of the float; the butyl rubber layer 54 has excellent air tightness and water tightness, which can prevent gas and water penetration; the EVA and nano calcium carbonate composite layer 55 enhances the internal hardness and wear resistance of the float, improves its flame retardant properties, and further stabilizes the internal structure.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
