Description

Technical Field

[0001] The utility model relates to the technical field of composite materials, in particular to a porous membrane of a diversion net. Background Art

[0002] During the vacuum infusion molding process, auxiliary materials such as release cloth, isolation film, flow guide mesh, and vacuum bagging film are sequentially placed on the surface of the main material in the mold. Due to the large size of products such as wind turbine blades, yachts, and aerospace, laying each auxiliary material takes a considerable amount of time, resulting in a lengthy molding process and low production efficiency.

[0003] China Patent Authorization Publication Number: CN 205522813 U, Authorization Publication Date: August 31, 2016. This utility model relates to a composite material of a diversion net and a porous separator membrane, characterized by comprising a diversion net and a porous separator membrane, the diversion net and the porous separator membrane being bonded together, wherein the porous separator membrane is composed of at least two membranes stacked one above the other, and the entire porous separator membrane is provided with a plurality of holes. However, a disadvantage of this technical solution is that the diversion net and the porous separator membrane are connected as a whole using adhesive, but the wide range of adhesive and comprehensive bonding are not environmentally friendly, are time-consuming to manufacture, and have a flow-blocking effect that affects diversion efficiency.

[0004] In summary: the porous isolation membrane of the diversion net has the disadvantages of being difficult to use and affecting the diversion efficiency. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art porous isolation membrane of the guide net, which is difficult to use and affects the guide efficiency, and provides a guide net porous membrane which is easy to use and improves the guide efficiency.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A porous membrane of a diversion net comprises a mesh, an isolation diaphragm and a connecting coil. The mesh and the isolation diaphragm are sewn together into an integrated structure through the connecting coil. The mesh is provided with diversion mesh holes, and the isolation diaphragm is provided with membrane holes. There are a plurality of diversion mesh holes and membrane holes, and the holes are evenly arranged.

[0008] The mesh is provided with a number of diversion mesh holes to form a diversion net to divert the irrigation liquid. The isolation diaphragm is provided with a number of uniform membrane holes to form a porous membrane to facilitate diversion. The mesh and isolation diaphragm are sewn together into an integrated structure through connecting coils, so that the diversion net and porous membrane can be laid simultaneously during laying, thereby reducing manpower, simplifying the laying process, and improving efficiency. The sewing method simplifies the synthesis method of the diversion porous membrane and eliminates the need for glue and thermoplastic bonding, simplifying the production process while achieving environmental protection. In addition, compared with the flow resistance of glue bonding to the perfusion liquid, the fluidity is greatly enhanced to improve the diversion effect. The results achieve the effects of reducing manpower, simplifying the laying process, thereby improving efficiency and ease of use, simplifying the production process, achieving environmental protection, and improving diversion effect.

[0009] Preferably, the connecting coils are interlaced with the membrane holes and the guide mesh holes. When sewing the mesh and the isolation diaphragm together, the connecting coils are arranged so as to intersperse the membrane holes and the guide mesh holes vertically. This prevents damage to the mesh and isolation diaphragm structures, thereby ensuring integrity and structural strength, thereby improving integrity and structural strength.

[0010] Preferably, multiple connecting coils are provided and evenly spaced. Multiple connecting coils are evenly spaced on the surface of the surface mesh (isolating diaphragm), enhancing structural strength while facilitating subsequent cutting, thereby improving ease of use.

[0011] Preferably, the connecting coil has a rectangular shape. During sewing, the connecting coil is shaped in a rectangular shape, simplifying the sewing requirements while ensuring the sewing strength of the mesh and the isolation diaphragm. This achieves the effect of facilitating fabrication and ensuring structural strength.

[0012] Preferably, the connecting coil is made of cotton material. The connecting coil body is a cord structure made of cotton material to improve the overall spreading and guiding performance, thereby further improving the guiding efficiency.

[0013] Preferably, the holes of the diversion mesh are in a diamond shape, so as to ensure the diversion effect of the mesh through each diamond-shaped mesh hole, thereby improving production efficiency.

[0014] The beneficial effects of the present invention are: reducing manpower, simplifying the laying process and thus improving efficiency; simplifying the production process and achieving environmental protection; improving the diversion effect; facilitating the production of the structure; improving the integrity and structural strength; improving the ease of use; and improving production efficiency.

[0024] Example 1:

[0025] like Figure 1-4 As shown, a porous membrane of a guide mesh includes a mesh 1, an isolation diaphragm 2 and a connecting coil 3. The mesh 1 and the isolation diaphragm 2 are sewn together into an integrated structure through the connecting coil 3. The mesh 1 is provided with a guide mesh 4, and the isolation diaphragm 2 is provided with a membrane hole 5. There are several guide mesh holes 4 and membrane holes 5 and they are evenly arranged.

[0026] like Figure 1 As shown, the connecting coil 3 is connected to the membrane hole 5 and the guide mesh hole 4 through insertion.

[0027] like Figure 4 As shown, there are several connecting coils 3 and they are evenly arranged. The structural shape of the connecting coils 3 is rectangular. The connecting coils 3 are made of cotton material.

[0028] like Figure 3As shown, the hole shape of the guide mesh 4 is diamond-shaped.

[0029] like Figure 1-4 As shown: the size of the connecting coil 3 is determined by the actual usage scenario. When used in a larger area mold, a correspondingly large-sized connecting coil 3 guide mesh porous membrane is used. When used in a smaller mold, a small-sized connecting coil 3 guide mesh porous membrane is used to avoid material waste and ensure integrity in the mold.

[0030] During production: Use the connecting coils 3 of cotton thread to sew the mesh 1 (guide mesh) and the diaphragm 2 (porous isolation membrane) through sewing equipment. Avoid puncturing the main structure of the mesh 1 and the diaphragm 2 during suturing. Use the evenly arranged connecting coils 3 to overlap and sew the mesh 1 and the diaphragm into one.

[0031] When using: After laying the release cloth on the mold, cut the guide mesh porous membrane of appropriate size (avoid cutting to the connecting coil 3), lay the guide mesh porous membrane on the release cloth, and then lay the vacuum bag film on the guide mesh porous membrane. The laying of the guide mesh and porous isolation membrane can be completed at one time.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
