[0028] In construction projects, safety nets are often used to prevent falling objects and people from heights, and they are frequently required during construction. However, these nets are constantly exposed to the outdoor environment, making them susceptible to accumulating dust, leaves, sand, and other debris that reduces air permeability and light transmission, impacting the construction environment and making cleaning difficult.

[0029] This utility model proposes a self-cleaning structure for protective netting.

[0030] Please see Figure 1 and Figure 2In one embodiment of the present invention, the self-cleaning structure of the protective net includes a net body 1, a photocatalytic layer 2 is provided on the outside of the net body 1, an enhancement layer 3 is provided on the outside of the photocatalytic layer 2, and a hydrophobic layer 4 is provided on the outside of the enhancement layer 3.

[0031] In the technical solution of this utility model, the photocatalytic coating receives light to activate the photocatalytic reaction, decompose organic pollutants, and reduce the adhesion of pollutants; the reinforcing layer 3 serves as an intermediate layer, which protects the photocatalytic coating and improves the overall wear resistance and adhesion; after water droplets fall onto the hydrophobic layer 4, they can easily roll off, achieving a self-cleaning function; overall, the protective net can achieve a self-cleaning function through sunlight and rain.

[0032] The photocatalytic layer 2 includes a nano-titanium dioxide layer. When the mesh 1 of the protective net is exposed to sunlight (including ultraviolet or visible light), the surface nano-titanium dioxide layer is activated, generating highly oxidizing hydroxyl radicals and superoxide radicals. This oxidizing property decomposes organic pollutants attached to the substrate surface and harmful gases in the air such as sulfur dioxide, nitrogen oxides, hydrogen sulfide, and ammonia.

[0033] The nano-titanium dioxide layer is coated using an dip-coating method, in which the protective net is completely immersed in the sol and pulled up at a uniform speed of 3-5 cm / min. This dip-coating is repeated 2-3 times to form a uniform photocatalytic layer 2.

[0034] The intermediate layer includes a fluorocarbon resin layer, which serves to protect the inner coating and improve overall wear resistance and adhesion. The fluorocarbon resin layer is applied to the nano-titanium dioxide layer by spraying.

[0035] The hydrophobic layer 4 includes a superhydrophobic siloxane coating. This coating enables water droplets to roll off more quickly, facilitating the removal of contaminants. The superhydrophobic siloxane coating is applied using a dip-coating method, where the protective mesh is immersed in a superhydrophobic siloxane sol and slowly pulled out to form a uniform film. It is then allowed to dry naturally, allowing the siloxane molecules to hydrolyze and condense, constructing a micro / nano-structured superhydrophobic surface.

[0036] Please see Figure 1 and Figure 3 The self-cleaning structure of the protective net also includes a water delivery hose 5, which is used to connect to a water source. The water delivery hose 5 is arranged along the extension direction of the net body 1, and a spray section 51 is provided on the water delivery hose 5. By providing the water delivery hose 5, water droplets can be sprayed out through the spray section 51 even when it does not rain for a long time, so that the water droplets fall onto the net body 1, making it easier to remove dirt adhering to the net body 1.

[0037] The spray unit 51 can be a nozzle or spray outlet installed on the water spray hose. The number and distance of the spray units 51 on the water spray hose can be set as needed and are not limited here.

[0038] Please see Figure 3 and Figure 4 The net body 1 has mesh openings 11, and the water delivery hose 5 passes through multiple mesh openings 11 in sequence. This allows the water delivery hose 5 to be conveniently positioned around the extension direction of the protective net.

[0039] The water delivery hose 5 has a first end and a second end. The first end has an external thread, and the second end has an internal thread. The first and second ends of the two water delivery hoses 5 are respectively threaded and adapted to each other. This allows multiple water delivery hoses 5 to be spliced ​​together to increase the spray range of water droplets.

[0040] The first end and the second end can also be threaded to a sealing component to achieve a seal on the end of the water delivery hose 5.

[0041] The self-cleaning structure of the protective net also includes a limiting part 6, which is disposed on the net body 1 and connected to the water delivery hose 5. The limiting part 6 is used to limit the rotation of the water delivery hose 5. By setting the limiting part 6, the spraying range of the spraying part 51 can be kept constant.

[0042] The limiting part 6 extends along the width direction of the mesh body 1 and passes through multiple mesh holes 11 in sequence. This facilitates the installation and fixation of the limiting part 6. The material and shape of the limiting part 6 are not limited here.

[0043] Please see Figure 3 and Figure 4 The limiting part 6 is provided in multiple parts, with a portion of the limiting part 6 located on one side of the water supply hose 5 and another portion located on the other side of the water supply hose 5. This allows the water supply hose 5 to be limited from opposite sides, improving the stability of its installation.

[0044] The water delivery hose 5 has a plurality of first engaging portions 521 arranged sequentially on its periphery, and a second engaging portion 61 is provided on the limiting portion 6. One of the first engaging portion 521 and the second engaging portion 61 is a slot, and the other is a block. The slot and the block are inserted and adapted to each other. Through the cooperation of the first engaging portion 521 and the second engaging portion 61, the water delivery hose 5 can be fixed at a corresponding angle as needed.

[0045] The locking block is located on the water delivery hose 5, and the locking groove is located on the locking part.

[0046] Please see Figure 3 and Figure 4 The water delivery hose 5 is detachably and fixedly mounted with an installation part 52, and multiple first snap-fit ​​parts 521 are provided on the installation part 52. This facilitates the installation of the installation part 52 on the water delivery hose 5 after it has been installed on the mesh body 1, and also facilitates the passage of the water delivery hose 5 through the mesh opening 11 and the installation of the water delivery hose 5 on the mesh body 1.

[0047] The mounting part 52 can be a mounting strip, which is wrapped around the water supply hose 5. The inner side of the mounting strip is provided with a hole, and the outer side of the water supply hose 5 is provided with a plug. The plug is inserted into the hole, which can reduce the mutual rotation between the mounting part 52 and the water supply hose 5.

[0048] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
