Description

Technical Field

[0001] The present application relates to the field of rubber dams, and in particular to an anti-fouling rubber dam suitable for being filled with water or air. Background Art

[0002] Traditional rubber dams are mainly used in water conservancy projects to control water flow, store water and prevent floods. These dams generally adopt a single structure, that is, they are composed of a single material or structure without special anti-fouling treatment. In particular, the part of the dam body located below the water level is very easy to be attached with various dirt and microorganisms. These dirt not only affects the appearance of the dam body, but also may cause structural damage, reducing the performance and service life of the dam body.

[0003] More specifically, due to long-term exposure to water, the surface of existing inflatable or water-filled rubber dams is prone to sediment, algae and other microorganisms, resulting in surface contamination. This contamination not only makes cleaning difficult, as professionals need to be regularly arranged for physical cleaning, a process that is both time-consuming and labor-intensive, but may also cause damage to the dam body. In addition, frequent cleaning and maintenance significantly increase the operating costs of the rubber dam. What's more serious is that long-term contamination may damage the dam material, thereby affecting its normal working performance. Therefore, solving the problem of surface contamination is crucial to improving the efficiency and life of the rubber dam.

[0004] In summary, the existing rubber dams have significant room for improvement due to the lack of effective anti-fouling measures and structures. Utility Model Content

[0005] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide an anti-fouling rubber dam with an improved structural design of the dam body to prevent dirt from adhering or promote the natural shedding of dirt.

[0006] To achieve the above-mentioned purpose, the present application discloses an anti-fouling rubber dam, the dam wall of which is a multi-layer composite structure, which comprises a structural layer group, an anti-fouling rubber layer, and a hydrophobic coating from the inside to the outside, wherein the structural layer group provides structural strength and deformation toughness and is vulcanized into one by intersecting multi-layer rubber layers and canvas layers;

[0007] The surface of the anti-fouling rubber layer that improves anti-fouling function is dense and has no pores;

[0008] The hydrophobic coating is coated on the outer surface of the antifouling rubber layer.

[0009] Furthermore, the rubber layer cooperates with the anti-fouling rubber layer in the structural layer group, and the rubber layer is vulcanized and fixedly connected with the anti-fouling rubber layer as a whole.

[0010] Furthermore, the surface of the anti-fouling rubber layer is in the shape of fish scales, and the hydrophobic coating fills the surface of the anti-fouling rubber layer.

[0024] Embodiment 1:

[0025] Reference Figure 1The present application discloses an exemplary structure of an anti-fouling rubber dam, as shown in the figure, which adopts an innovative multi-layer composite structure designed to enhance the durability and anti-fouling performance of the dam body.

[0026] Specifically, the structural layer group 1 is located inside the dam body and is the core part of the dam body. It is composed of multiple layers of rubber layers 2 and canvas layers 3 arranged alternately. Among them, the rubber layer 2 provides the basic elasticity and sealing of the dam body, so that the dam body can withstand deformation without breaking. The canvas layer 3 increases the strength and durability of the rubber layer, helps maintain the shape of the dam body, and resists external pressure and tearing. These layers are tightly combined by high-strength adhesives or advanced vulcanization processes to ensure the firmness and sealing of the overall structure.

[0027] In this embodiment, the anti-fouling rubber layer 4 is located on the outside of the structural layer group 1, and its surface is dense and pore-free, forming a smooth and uniform surface to prevent the infiltration of microorganisms and silt. More specifically, the anti-fouling rubber layer 4 is a specially designed rubber material layer used to prevent the attachment and accumulation of pollutants, provide a protective barrier, and prevent silt, microorganisms and other pollutants from attaching to the surface of the rubber dam, especially in the underwater part. It is usually made of durable synthetic rubber or natural rubber, which is specially treated to enhance its anti-fouling performance. As some improved embodiments, anti-ultraviolet agents and other reinforcing agents are also included in the layer to improve the anti-fouling, aging and environmental resistance of the rubber layer.

[0028] In this embodiment, the hydrophobic coating 5 is coated on the outermost of the anti-fouling rubber layer 4 to further enhance the anti-fouling ability. The hydrophobic coating 5 helps water and other liquids roll off by creating a water-repellent surface, reduces the accumulation of dirt, and makes it difficult for water and aqueous solutions to form adhesion on the surface of the material, thereby effectively preventing the accumulation of liquids and pollutants. The hydrophobic coating 5 is usually made of nano-scale high molecular polymers, silicon-based compounds or fluoropolymers, etc. These materials have natural hydrophobic properties. The use of nano-scale materials can further enhance the hydrophobic properties of their microstructures. It can cooperate with the anti-fouling rubber layer 4 to realize the dam body's resistance to erosion by various chemical substances, including grease, acid and alkali. And due to the presence of the hydrophobic coating 5, water droplets can easily carry away pollutants on the surface, so that the dam body has a certain self-cleaning ability.

[0029] It should be understood that the specific formula and process of the anti-fouling rubber layer 4 and the hydrophobic coating 5 are all available for reference in a large number of prior arts, which should be considered as prior arts, and thus will not be described in more detail.

[0030] Embodiment 2:

[0031] like Figure 2 and 3As shown, the difference between this embodiment and embodiment 1 is that the anti-fouling rubber layer 4 has a fish scale-like surface, and the hydrophobic coating 5 fills the concave and convex surface of the anti-fouling rubber layer 4. This unique design imitates the structure of fish scales and aims to improve its anti-fouling and hydrophobic properties. More specifically, the surface of the anti-fouling rubber layer 4 is composed of tiny concave and convex shapes, similar to the natural arrangement of fish scales. This structure reduces the surface area directly contacted by pollutants and reduces the adhesion ability of pollutants. At the same time, the microscopic concave and convex structure promotes the sliding of water flow on the surface and helps to naturally remove attachments.

[0032] In addition, the hydrophobic coating 5 fills the microscopic concavo-convex of the fish-scale surface, thereby creating a smoother and more uniform surface. The above structure can retain more hydrophobic coating 5 material, increase the thickness of the hydrophobic coating 5 on the fish-scale anti-fouling rubber layer 4, and after the hydrophobic coating 5 is consumed to a certain extent, the advantages of the microscopic concavo-convex structure can be maintained, while providing a more solid protective layer.

[0033] It is understood that more hydrophobic coating 5 material means that even if the surface portion is lost due to wear or aging, the underlying material can still provide a lasting hydrophobic and anti-fouling effect. This design reduces the need for frequent maintenance and re-coating due to coating loss, thereby reducing long-term maintenance costs. Although exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without essentially departing from the spirit and scope of the present disclosure. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
