Description

Technical Field

[0001] The utility model relates to the technical field of yacht manufacturing, in particular to a glass fiber reinforced plastic hull water flow hole installation structure. Background Art

[0002] To reduce hull weight and increase rigidity, many high-end yachts currently utilize sandwich panels for their hull plating. Sandwich panels incorporate a lightweight core material between fiberglass outer and inner panels. Currently, the most commonly used core material is foam. By layering fiberglass sheets on both sides of the hull, sandwich panels enhance the structural efficiency of the hull, increasing its bending strength while reducing its thickness.

[0003] When installing metal parts that pass through the water holes on the sandwich panels, due to the low compression strength and compression modulus of the core material, after the metal parts are pressed tightly, the core material will produce a large deformation under pressure, causing the two sides of the shell plate to sag inward, which not only affects the appearance of the exterior of the hull, but also after long-term compression, the creep of the core material will cause gaps between the metal parts and the shell plate, resulting in leakage and affecting the safety of the hull. Utility Model Content

[0004] In view of the defects of the above existing technologies, the utility model provides a glass fiber reinforced plastic hull water hole installation structure to solve the problem that the hull shell of the sandwich plate structure is prone to leakage at the water hole position.

[0005] The utility model is implemented by the following technical solutions:

[0006] A fiberglass hull water hole installation structure includes a hull shell, the hull shell includes a fiberglass outer plate, a fiberglass inner plate and a core material layer sandwiched between the fiberglass outer plate and the fiberglass inner plate, the hull shell is provided with a water hole for installing a water outlet component, the water hole passes through the fiberglass inner plate, the core material layer and the fiberglass outer plate from the inside to the outside in sequence, the water hole is provided with a hollow area at the circumferential side of the core material layer, and the hollow area is filled with a glass fiber layer.

[0007] Furthermore, the glass fiber layer is made of chopped glass fibers.

[0008] Furthermore, the depth of the hollowed-out area is 50 mm.

[0009] Furthermore, the core material layer is made of PVC foam.

[0010] Furthermore, the water outlet member is fixed to the water flow hole through a pressing member.

[0011] Furthermore, sealant is provided at the contact position between the pressing member and the hull plate.

[0012] Furthermore, the thickness of the FRP outer plate is greater than the thickness of the FRP inner plate.

[0013] Compared with the prior art, the beneficial effects of the present invention include at least:

[0014] The utility model fills the peripheral side of the water flow hole with a glass fiber layer. Since the glass fiber layer has high strength and is not easy to deform, the water outlet part can be compacted in the water flow hole, and it is not easy to produce a gap between the water outlet part and the hull shell, effectively avoiding deformation of the fiberglass reinforced plastics on the inner and outer surfaces of the hull and subsequent leakage.

[0017] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the figures denote identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0018] The words expressing positions and directions described in this utility model are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of this utility model.

[0019] like Figure 1 As shown, a fiberglass hull water flow hole installation structure provided by the utility model includes a hull shell 1, wherein the hull shell 1 includes a fiberglass outer plate 11, a fiberglass inner plate 12 and a core material layer 13 sandwiched between the fiberglass outer plate 11 and the fiberglass inner plate 12, and the hull shell 1 is provided with a water flow hole 14 for installing a water outlet part 2, and the water flow hole 14 passes through the fiberglass inner plate 12, the core material layer 13 and the fiberglass outer plate 11 from the inside to the outside in sequence, and the water flow hole 14 is provided with a hollow area at the peripheral side of the core material layer 13, and the hollow area is filled with a glass fiber layer 15.

[0020] In this embodiment, a hole is first drilled through the hull plate 1 at the position where the water hole 14 needs to be installed using a hole opener. The diameter of the hole is approximately 1 mm larger than the outer diameter of the water outlet component 2, which facilitates the installation of the water outlet component 2. Then, an electric drill is used to remove the core material layer 13 around the water hole 14 to form a hollow area, which is then filled with a glass fiber layer 15. After that, the water outlet component 2 is installed in the water hole 14. Since the glass fiber layer 15 is filled at the connection part of the water hole 14, the glass fiber layer 15 has high strength and is not easy to deform, so that the water outlet component 2 can be compacted in the water hole 14, and it is not easy to generate a gap between the water outlet component 2 and the hull plate 1, effectively avoiding deformation of the fiberglass reinforced plastics on the inner and outer surfaces of the hull and subsequent leakage.

[0021] As a preferred embodiment, the glass fiber layer 15 is made of chopped glass fibers.

[0022] In this embodiment, the hollowed area can be filled with resin-impregnated chopped glass fibers. After the glass fibers solidify, the burrs around the water flow hole 14 are smoothed with a grinding head. Then, the water outlet 2 can be installed from the outside in. The chopped glass fibers become soft after being impregnated with resin, making them easy to handle during filling. They also conform to the material of the FRP outer panel 11 and the FRP inner panel 12, providing good connection strength.

[0023] As a preferred embodiment, the depth of the hollowed area is 50 mm.

[0024] As a preferred embodiment, the core material layer 13 is made of PVC foam.

[0025] As a preferred embodiment, the water outlet member 2 is fixed to the water flow hole 14 via a pressing member 4. The water outlet member 2 can be pressed against the water flow hole 14 by the pressing member 4. The pressing member 4 is preferably a pressing nut.

[0026] As a preferred embodiment, a sealant 3 is provided at the contact position between the pressing member 4 and the hull plate 1, so that an effective seal is formed between the water outlet member 2 and the hull plate 1 to avoid leakage.

[0027] As a preferred embodiment, the thickness of the fiberglass outer plate 11 is greater than the thickness of the fiberglass inner plate 12. This can increase the strength of the hull and ensure that the outer surface of the hull plate 1 has strong impact resistance.

[0028] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limiting the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the present invention.
