Description

TECHNICAL FIELD

[0001] The utility model relates to a vortex -breaking fin technical field, concretely relates to a vortex -breaking fin of quick assembly and disassembly. BACKGROUND

[0002] In order to reduce operating cost, save fuel, many ships are installed with energy-saving devices, and typical energy-saving devices include energy-saving ducts, vortex-breaking fins, rudders and the like. Among them, the vortex-breaking fin installed at the front of the propeller is a device similar to a small propeller, which rotates with the propeller. The vortex-breaking fin can absorb the tail vortex generated by the propeller during rotation, improve the wake field, and help improve the propeller propulsion efficiency to achieve energy saving.

[0003] As shown in the reference case "A vortex-breaking fin easy to install" with publication number "CN216709601U", by setting the connecting structure, the hexagonal plug inside the connecting structure cooperates with the hexagonal slot inside the main body, which can quickly connect the main body with the propeller, and is convenient to disassemble. The hexagonal plug and the hexagonal slot can be quickly positioned when cooperating with the connection, improving the connection efficiency. Moreover, the inner fixing sleeve on the outer side of the screw rod cooperates with the inner connecting thread to quickly fix the main body, which is convenient to connect and use.

[0004] The existing vortex-breaking fin design is usually an integral structure of the main body and multiple fins. If one of the fins is damaged or broken, the entire vortex-breaking fin often needs to be replaced, which not only increases the maintenance cost, but also causes resource waste.

[0005] Based on this, the utility model designs a vortex-breaking fin that can be quickly assembled and disassembled to solve the above problems. INVENTION CONTENTS

[0006] In view of the above shortcomings of the prior art, the utility model provides a vortex-breaking fin that can be quickly assembled and disassembled.

[0007] To achieve the above purpose, the utility model is implemented by the following technical solutions:

[0009] Furthermore, the disassembly assembly includes multiple insertion holes on the surface of the main body, with multiple fins slidably connected to the multiple insertion holes respectively. A fixing block is fixedly connected to one side of each insertion hole, and a positioning block is slidably connected to the other side of each insertion hole. A support plate is provided on one side of the positioning block and is fixedly connected to the main body. A screw is rotatably mounted on the surface of the support plate, and one end of the screw is threadedly connected to the positioning block. The positioning block and the adjacent fixing block are located on both sides of the fins respectively.

[0010] Furthermore, the disassembly assembly also includes rubber plates fixedly installed on the adjacent side of the positioning block and the fixing block, with both rubber plates abutting against the fins.

[0011] Furthermore, a limiting rod is fixedly connected to one side of the fixing block, and a positioning hole is opened on the surface of the fin, through which the limiting rod passes.

[0012] Furthermore, the surface of the positioning block is provided with a limiting hole that penetrates the adjacent rubber plate, and one end of the limiting rod is slidably connected to the adjacent limiting hole.

[0013] Furthermore, the protective component includes a protective cover fitted over the outside of the positioning block, one side of which is slidably connected to the surface of the main body.

[0015] Furthermore, a rubber ring is provided on the outside of the screw hole, and the rubber ring is fixedly connected to the connecting block. Beneficial effects

[0016] When a single fin is damaged during use, it can be disassembled and replaced individually by disassembling the assembly, avoiding the need to replace the entire anti-vortex fin. This effectively reduces resource waste and replacement costs. The protective assembly protects the disassembly assembly from external damage, ensuring the safety and long-term stability of the disassembly operation.

The function of the limiting rod is to restrict the lateral movement of the fin, thereby improving the fixing accuracy of the fin. After passing through the positioning hole of the fin, the limiting rod can slide and connect with the limiting hole on the rubber plate, improving the overall fixing firmness.
