Description

Technical Field

[0001] This utility model relates to the field of mounting bracket technology, specifically to a hybrid propulsion bracket for ships. Background Technology

[0002] In the field of marine propulsion systems, hybrid propulsion systems combine the advantages of traditional mechanical propulsion and electric propulsion, and have become an important feature of modern ships, especially special engineering vessels, research vessels, and high-end yachts. These propulsion systems are typically fixed to the exterior of the hull or a specific compartment using a dedicated support structure, and their installation stability directly affects propulsion efficiency, navigation safety, and equipment lifespan.

[0003] In practical use, existing hybrid propeller supports must withstand the static gravity of the propeller body and accessories for a long time, especially in large ships where the static load is significant. During navigation operations, the supports are also continuously subjected to multi-directional impact forces from the water flow, as well as complex mechanical vibrations generated by the propeller operation. These combined loads formed by gravity, water flow impact forces, and self-vibration act on the support structure in a long-term and alternating manner, which can easily lead to stress concentration at welded joints, bolted connections, and abrupt structural changes, inducing fatigue microcracks.

[0004] Therefore, a hybrid propulsion bracket for ships is proposed. Utility Model Content

The bottom surface of the connecting plate is fixedly mounted with a connecting column, and the surface of the connecting column is provided with a second mounting hole corresponding to the first mounting hole on the surface of the connecting seat. Two sets of reinforcing ribs are welded to the bottom surface of the connecting plate and the surface of the connecting column. The top surface of the connecting plate is provided with a damping mounting mechanism, and bolts are inserted into the second mounting hole and the first mounting hole for mounting the hybrid propulsion unit.

[0007] Furthermore, a limiting ring is provided on the surface of the connecting post, and when the end of the connecting post is inserted into the connecting seat, the top end of the connecting seat fits against the bottom end of the limiting ring.

[0008] Furthermore, bolts are inserted into the first and second mounting holes, and sealing rubber rings are fitted on both ends of the bolts, with the end faces of the sealing rubber rings tightly fitting the outer surface of the connecting seat.

[0018] like Figures 1 to 4 As shown, a hybrid propulsion bracket for a ship includes a hybrid propulsion 1 and a connecting plate 3. The top surface of the hybrid propulsion 1 is provided with a connecting seat 2, and the surface of the connecting seat 2 is provided with a first mounting hole 21. The bottom surface of the connecting plate 3 is fixedly installed with a connecting column 4, and the surface of the connecting column 4 is provided with a second mounting hole 41 corresponding to the first mounting hole 21 on the surface of the connecting seat 2. Two sets of reinforcing ribs 5 are welded to the bottom surface of the connecting plate 3 and the surface of the connecting column 4. The top surface of the connecting plate 3 is provided with a damping mounting mechanism 6, and bolts 7 are inserted into the second mounting hole 41 and the first mounting hole 21 for installing the hybrid propulsion 1. like Figure 3 and Figure 4As shown, specifically, the damping mounting mechanism 6 includes a spring 601 and a first rubber sleeve 602 fixedly mounted on the top surface of the connecting plate 3. The first rubber sleeve 602 is located outside the spring 601. The top surfaces of the connecting plate 3 and the connecting column 4 are provided with mounting grooves, and a hydraulic damping rod 604 is fixedly mounted in the mounting grooves. A second rubber sleeve 605 is fixedly connected between the connecting plate 3 and the mounting plate 603. The hydraulic damping rod 604 is located inside the second rubber sleeve 605. The top ends of the spring 601, the first rubber sleeve 602, and the hydraulic damping rod 604 are fixedly mounted with the mounting plate 603.

[0019] More specifically, the spring 601 provides basic elastic support to absorb high-frequency vibrations, the hydraulic damping rod 604 is embedded in the mounting groove to dissipate low-frequency vibrations and impact energy through hydraulic oil, and the first rubber sleeve 602 and the second rubber sleeve 605 protect the mechanical energy of the spring 601 and the hydraulic damping rod 604 inside.

[0020] In practical applications, multiple sets of springs 601 and the first rubber sleeve 602 are arranged in correspondence with the mounting holes on the surfaces of the connecting plate 3 and the mounting plate 603.

[0021] More specifically, by arranging multiple sets of springs 601 and the first rubber sleeve 602 in correspondence with the mounting holes of the connecting plate 3 and the mounting plate 603, a multi-point support system is formed to ensure that vibration energy is absorbed and dissipated synchronously, thereby improving the overall balance and shock absorption efficiency of the support.

[0022] In practical applications, a limiting ring 42 is provided on the surface of the connecting post 4. When the end of the connecting post 4 is inserted into the connecting seat 2, the top end of the connecting seat 2 is in contact with the bottom end of the limiting ring 42.

[0023] More specifically, when the connecting post 4 is inserted into the connecting seat 2, the top end of the connecting seat 2 contacts the bottom end of the limiting ring 42, forming an axial block.

[0024] In practical applications, bolts 7 are inserted into the first mounting hole 21 and the second mounting hole 41, and both ends of the bolts 7 are fitted with sealing rubber rings 71, the end faces of which are tightly fitted with the outer surface of the connecting seat 2.

[0025] More specifically, after the bolts 7 are inserted into the first mounting hole 21 and the second mounting hole 41, the sealing rubber rings 71 at both ends are pressed against the outer surface of the connecting seat 2 to form a dynamic seal, which not only prevents seawater from entering.

[0026] In practical applications, the surface of the reinforcing rib 5 is curved, and the reinforcing rib 5 is axially parallel to the hybrid thruster 1.

[0027] More specifically, the reinforcing rib 5 adopts a curved surface design and is parallel to the axis of the hybrid propeller 1, so that when the reinforcing rib 5 is subjected to the impact force of water flow, the load can be smoothly distributed along the curved surface, avoiding stress concentration at right angles or sharp corners.

[0028] In summary: The connecting column 4 is inserted into the interior of the connecting seat 2. After the first mounting hole 21 on the connecting seat 2 and the second mounting hole 41 on the connecting column 4 are aligned, a rigid connection is achieved by bolts 7. The reinforcing rib 5 is welded to the bottom surface of the connecting plate 3 and the surface of the connecting column 4. The water-facing surface of the reinforcing rib 5 has an arc-shaped structure, which increases the contact area and structural continuity, disperses the impact force of water flow, and reduces stress concentration at the weld joint. The damping mounting mechanism 6 is set on the top surface of the connecting plate 3 to absorb the mechanical vibration generated by the hybrid propeller 1 during operation, reduce the fatigue effect of alternating load on the support structure, and thus extend the service life of the support.
