Description

Technical Field

[0001] This utility model relates to the field of ship rudder technology, and in particular to a segmented composite material rudder blade structure. Background Technology

[0002] The rudder blade is a crucial component in ship navigation, and its performance directly affects the ship's maneuverability, safety, and economy. Traditional rudder blades are mostly made of metal materials, such as cast steel and cast iron. Although they have high strength, they also have problems such as heavy weight, poor corrosion resistance, and complex manufacturing processes. With the development of composite material technology, composite material rudder blades have gradually been applied. Composite materials have advantages such as light weight, high strength, and good corrosion resistance, which can effectively improve the performance of rudder blades.

[0003] However, most existing composite material rudder blades are integral structures. During transportation, integral rudder blades occupy a lot of space and are inconvenient to transport. During installation and maintenance, integral rudder blades are difficult to disassemble and assemble, which increases the difficulty and cost of construction. In addition, when a part of the rudder blade is damaged, the whole blade needs to be replaced, resulting in waste of materials and increased costs. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: most existing composite material rudder blades are integral structures. During transportation, integral rudder blades occupy a lot of space and are inconvenient to transport. During installation and maintenance, integral rudder blades are difficult to disassemble and assemble, which increases the difficulty and cost of construction. In addition, when the rudder blade is partially damaged, it needs to be replaced as a whole, which results in waste of materials and increased costs. Therefore, a segmented composite material rudder blade structure is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A segmented composite material rudder structure includes a leading edge section, a middle section, a trailing edge section, and a cover assembly. Multiple insert plates with right-angled trapezoidal cross sections are fixedly installed on the back of the leading edge section and the back of the middle section. Multiple pairs of mounting holes are opened on the front surface of the middle section and the front surface of the trailing edge section. A spring rod is horizontally fixedly installed in the multiple mounting holes. A locking block with a triangular cross section is fixedly installed at one end of the spring rod. A rectangular slot for the locking block to be inserted is opened on the surface of the insert plate.

[0007] The upper surfaces of the middle section and the rear edge section are symmetrically and vertically provided with sliding openings that pass through two rows of mounting ports respectively. The free ends of multiple spring rods located in the same row are fixedly sleeved with pull plates. The tops of multiple pull plates protrude through the tops of multiple sliding openings respectively. The covering assembly is used to cover the tops of the front edge section, the middle section and the rear edge section.

[0008] Preferably, the covering assembly includes a housing, the surface of which has multiple pairs of movable openings with a T-shaped longitudinal section, and waterproof bolts are movably connected in the movable openings. The top of the front edge, middle edge and rear edge each has a pair of threaded holes, the multiple pairs of threaded holes correspond to the positions of the multiple pairs of movable openings, and the multiple waterproof bolts are threaded into the multiple threaded holes respectively.

[0009] Preferably, multiple insertion rods are vertically fixedly installed at the top of the housing, and slots for inserting multiple insertion rods are respectively opened at the top of the front edge, middle edge and rear edge.

[0010] Preferably, two pairs of rectangular blocks are fixedly installed at the top of the housing, and the two pairs of rectangular blocks correspond to the top positions of the two pairs of pull plates, and the bottom of the rectangular blocks is provided with a limiting opening for the top of the pull plate to be inserted.

[0011] Preferably, a storage opening is provided between each pair of movable openings, and an installation rod is fixedly installed in the middle of the storage opening. A cover plate is symmetrically slidably inserted into the storage opening. The cover plate is fixedly connected to the installation rod by a telescopic spring, and each cover plate covers the top opening of each movable opening.

[0012] Preferably, the top of the baffle is provided with a groove, and a friction block is fixedly embedded in the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This segmented composite material rudder structure divides the rudder into leading edge, middle, and trailing edge sections, enabling separate loading during transportation. This significantly reduces space occupation, transportation difficulty, and costs. With the help of insert plates, spring rods with locking blocks, and pull plates, the segments can be quickly connected and disassembled without complicated tools, simplifying the installation process and improving construction efficiency. When a local section is damaged, only the pull plate needs to be pulled to remove and replace the damaged segment, eliminating the need for complete replacement, reducing material waste, and significantly lowering maintenance costs.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0030] Reference Figures 1-3A segmented composite material rudder blade structure includes a leading edge section 1, a middle section 2, a trailing edge section 3, and a cover assembly. The leading edge section 1, middle section 2, and trailing edge section 3 are all made of carbon fiber reinforced resin matrix composite material, possessing advantages such as high strength, lightweight, and corrosion resistance. The overall design achieves convenient transportation, efficient installation, and economical maintenance, significantly improving the comprehensive performance of the rudder blade. Multiple insert plates 5 with right-angled trapezoidal cross-sections are fixedly installed on the back of the leading edge section 1 and the back of the middle section 2. Multiple pairs of mounting ports 4 are opened on the front surface of the middle section 2 and the front surface of the trailing edge section 3. Figure 8 and Figure 12 As shown, multiple mounting ports 4 are horizontally fixedly installed with spring rods 6, and one end of each spring rod 6 is fixedly installed with a locking block 7 with a triangular cross-section, as shown. Figure 9 As shown, the surface of the insert plate 5 has a rectangular slot 8 for the insertion of the card block 7.

[0031] Reference Figures 7-8 The upper surfaces of the middle section 2 and the rear edge section 3 are symmetrically and vertically provided with sliding openings 9 that pass through two rows of mounting openings 4 respectively. The free ends of multiple spring rods 6 located in the same row are fixedly sleeved with pull plates 10. The tops of multiple pull plates 10 respectively pass through the tops of multiple sliding openings 9. The covering assembly is used to cover the tops of the front edge section 1, the middle section 2 and the rear edge section 3.

[0032] When assembling this segmented composite material rudder structure, the leading edge section 1 and the middle section 2, the middle section 2 and the trailing edge section 3 must be connected sequentially, and finally the cover assembly is installed.

[0033] When splicing the front edge segment 1 and the middle segment 2, first align the multiple right-angled trapezoidal cross-section insert plates 5 on the back of the front edge segment 1 with the multiple pairs of mounting holes 4 on the front surface of the middle segment 2. Then, slowly push the front edge segment 1 so that the insert plates 5 are gradually inserted into the mounting holes 4. During the insertion of the insert plates 5, their inclined surfaces will contact the triangular cross-section locking block 7 at one end of the spring rod 6 that is horizontally fixed in the mounting hole 4. As the insert plates 5 are continuously inserted, the locking block 7 will be squeezed, causing the spring rod 6 to contract. When the rectangular locking slot 8 on the surface of the insert plates 5 moves to the position corresponding to the locking block 7, the spring rod 6 will no longer be squeezed and will return to its original position, causing the locking block 7 to be locked into the rectangular locking slot 8, thus completing the initial fixing of the front edge segment 1 and the middle segment 2.

[0034] When splicing the middle section 2 and the rear edge section 3, the operation is similar to that described above. Align the insert plate 5 on the back of the middle section 2 with the mounting port 4 on the front surface of the rear edge section 3, push the middle section 2 so that the insert plate 5 is inserted into the mounting port 4, until the locking block 7 is engaged in the rectangular slot 8 of the insert plate 5, thus achieving the initial fixation of the middle section 2 and the rear edge section 3.

[0035] If it is necessary to adjust the position or split the segments during the splicing process, the pull plate 10 can be operated. The upper surfaces of the middle segment 2 and the rear edge segment 3 are symmetrically and vertically provided with sliding openings 9 that pass through the two rows of mounting openings 4 respectively. The free ends of multiple spring rods 6 located in the same row are fixedly sleeved with pull plates 10, and the top of the pull plate 10 extends out of the top of the sliding opening 9. Pulling two pull plates 10 located on the same horizontal line closer to each other will cause the pull plates 10 to drive the multiple spring rods 6 to retract, thereby causing the locking block 7 to disengage from the rectangular locking opening 8. At this time, the segments can be easily split.

[0036] After each segment is assembled, the cover component is installed on top of the rudder blade, covering the top of the leading edge segment 1, the middle segment 2 and the trailing edge segment 3, thus completing the assembly of the entire segmented composite material rudder blade structure.

[0037] Reference Figure 5 The covering component includes a housing 11, on the surface of which are multiple pairs of T-shaped movable openings 12. Waterproof bolts 13 (disclosed in publication number CN222863840U, patent name: Waterproof Sealing Bolt, which is prior art and its working principle will not be described in detail here) are movably connected in the movable openings 12. A pair of threaded holes 14 are provided at the top of the leading edge section 1, the middle section 2 and the trailing edge section 3. The multiple pairs of threaded holes 14 correspond to the positions of the multiple pairs of movable openings 12. The multiple waterproof bolts 13 are threaded into the multiple threaded holes 14 respectively.

[0038] After the front edge section 1, middle section 2 and rear edge section 3 are spliced ​​together, the cover assembly is installed. First, the housing 11 is placed on top of the spliced ​​rudder blade, so that the multiple pairs of T-shaped movable openings 12 on the surface of the housing 11 correspond to the positions of the multiple pairs of threaded holes 14 on the top of the front edge section 1, middle section 2 and rear edge section 3.

[0039] Next, align the waterproof bolts 13 that are movably connected in the movable port 12 with the corresponding threaded holes 14, and then slowly screw the waterproof bolts 13 into the threaded holes 14. As the screwing depth increases, the waterproof bolts 13 gradually fix the housing 11 to the top of the rudder blade. In the same way, thread all the waterproof bolts 13 into the corresponding threaded holes 14 to ensure that the housing 11 fits tightly with the top of each section, thus completing the installation of the cover assembly.

[0040] Through the above operations, the housing 11 can stably cover the top of the rudder blade, which can protect the internal structure and also help fix the leading edge section 1, the middle section 2 and the trailing edge section 3.

[0041] Reference Figure 4 Multiple insertion rods 15 are vertically fixedly installed inside the top of the housing 11. The top of the front edge section 1, the middle section 2 and the rear edge section 3 are each provided with a slot 16 for inserting multiple insertion rods 15.

[0042] When installing the housing 11 of the cover assembly, as the housing 11 is placed on top of the assembled rudder blade and the movable opening 12 on the surface of the housing 11 corresponds to the threaded hole 14 on the top of each segment, multiple vertically fixed insert rods 15 inside the top of the housing 11 will simultaneously align with multiple slots 16 opened on the top of the leading edge segment 1, the middle segment 2 and the trailing edge segment 3. Subsequently, during the placement of the housing 11, the multiple insert rods 15 will be inserted into the corresponding slots 16 one by one to complete the initial positioning of the housing 11.

[0043] The engagement of the insert rod 15 and the slot 16 can accurately position the housing 11, facilitating the subsequent alignment and installation of the waterproof bolt 13 and the threaded hole 14, improving installation efficiency, and enhancing the connection stability between the housing 11 and each section, preventing the housing 11 from shaking or shifting during ship navigation.

[0044] Reference Figure 4 and Figure 10 Two pairs of rectangular blocks 17 are fixedly installed at the top of the housing 11. The two pairs of rectangular blocks 17 correspond to the top positions of the two pairs of pull plates 10 respectively, and the bottom of the rectangular blocks 17 is provided with a limiting opening 18 for the top of the pull plate 10 to be inserted.

[0045] When the housing 11 is installed, when the insert rod 15 at the top of the housing 11 is inserted into the slot 16 at the top of each segment, and the movable opening 12 corresponds to the threaded hole 14, the two pairs of rectangular blocks 17 fixedly installed at the top of the housing 11 will correspond to the top positions of the two pairs of pull plates 10 that protrude from the top of the sliding opening 9 on the middle segment 2 and the rear edge segment 3. As the housing 11 is lowered, the top of the pull plate 10 will gradually insert into the limiting opening 18 at the bottom of the rectangular block 17, thereby limiting and fixing the pull plate 10.

[0046] The constraint formed by the limiting opening 18 of the rectangular block 17 on the pull plate 10 can effectively prevent the pull plate 10 from moving unexpectedly due to external forces such as vibration and water flow impact during the ship's navigation, and prevent the locking block 7 from disengaging from the rectangular locking opening 8, thereby ensuring the stability of the connection of each section and further improving the reliability of the overall structure of the rudder blade.

[0047] Reference Figure 6 and Figure 11 Each pair of movable openings 12 has a storage opening 19. An installation rod 20 is fixedly installed in the middle of the storage opening 19. A cover plate 21 is symmetrically slidably inserted into the storage opening 19. The cover plate 21 is fixedly connected to the installation rod 20 through a telescopic spring 22. Each cover plate 21 covers the top opening of each movable opening 12. A groove is opened at the top of the cover plate 21, and a friction block 23 is fixedly embedded in the groove.

[0048] After the waterproof bolt 13 is installed, the cover plate 21 inside the storage port 19 slides symmetrically under the action of the telescopic spring 22, covering the top opening of the movable port 12. At this time, the bottom of the cover plate 21 abuts against the top of the waterproof bolt 13 inside the movable port 12, restricting the rotation of the waterproof bolt 13. When it is necessary to operate the waterproof bolt 13, the cover plate 21 is pushed by the friction block 23 to compress the telescopic spring 22, thus exposing the movable port 12. This can both cover the movable port 12 to protect the waterproof bolt 13 and prevent it from loosening. It is also convenient to operate, improving the structural stability and maintenance convenience.

[0049] In this invention, the segmented composite material rudder blade structure divides the rudder blade into a leading edge section 1, a middle section 2, and a trailing edge section 3, enabling separate loading during transportation. This significantly reduces space occupation, transportation difficulty, and costs. With the cooperation of the insert plate 5, the spring rod 6 with the locking block 7, and the pull plate 10, the segments can be quickly connected and disassembled without complicated tools, simplifying the installation process and improving construction efficiency. When a part is damaged, only the pull plate 10 needs to be pulled to remove and replace the damaged segment, eliminating the need for overall replacement, reducing material waste, and significantly lowering maintenance costs.

[0050] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
