[0018] 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.

[0019] Example 1 Please see Figure 1-10 This utility model provides a technical solution: a detachable epoxy baffle, comprising: A support assembly is installed outside the stern tube of the ship. The support assembly includes a first support frame 101 and a second support frame 102. The first support frame 101 has first fixing ears 103 fixedly installed on both sides for connection and fixation. The second support frame 102 has second fixing ears 104 fixedly installed on both sides corresponding to the first fixing ears 103. A fastening bolt 105 for detachable connection between the first fixing ears 103 and the second fixing ears 104 is provided. One end of the fastening bolt 105 is threaded with a fastening nut 106 for locking the first fixing ears 103 and the second fixing ears 104. When assembling the support assembly, the first support frame 101 and the second support frame 102 are respectively inserted from both sides of the stern tube of the ship, so that the first fixing lug 103 and the second fixing lug 104 are aligned. Then, the fastening bolt 105 is passed through the first fixing lug 103 and the second fixing lug 104, and the fastening nut 106 is tightened to connect and fix the first support frame 101 and the second support frame 102 to form a complete support assembly. This detachable connection method facilitates installation and disassembly, thereby achieving the function of convenient assembly and disassembly of the support assembly, and thus greatly improving the flexibility of the support assembly to adapt to different stern tube installation scenarios.

[0020] Epoxy baffles 2, mounted on the support assembly, are used to secure the sponge and prevent uncured epoxy from leaking out. Two sets of epoxy baffles 2 are provided, each set being semi-circular in shape. These two sets can be joined to form a complete disc structure to fit the outer contour of the ship's stern pipe. In use, the two sets of semi-circular epoxy baffles 2 are joined around the outer perimeter of the stern pipe to form a complete disc structure that fits the outer contour of the stern pipe better. This achieves a precise fit to the stern pipe's outer contour, significantly improving the securing effect of the epoxy baffles 2 on the sponge and preventing epoxy leakage.

[0021] The locking mechanism, installed on the support assembly, is used to lock and fix the support assembly to maintain its installation position. After the support assembly is installed in place, the locking mechanism is operated so that its components work together to apply a locking force to the support assembly, firmly fixing the support assembly to the stern tube of the ship and keeping its installation position unchanged. This achieves the function of stabilizing and fixing the support assembly, thereby greatly improving the stability of the support assembly during operation.

[0022] A screw fixing assembly, mounted on the support assembly, is used to cooperate with the epoxy baffle 2 to achieve fixed installation of the epoxy baffle 2. When installing the epoxy baffle 2, the screws 12 of the screw fixing assembly pass through the mounting holes 11 on the support assembly and are tightened in cooperation with the threaded holes 14 on the epoxy baffle 2, so that the epoxy baffle 2 is tightly connected to the support assembly, thereby achieving the fixed installation of the epoxy baffle 2. This achieves the function of firmly installing the epoxy baffle 2 on the support assembly, and thus greatly improves the installation firmness of the epoxy baffle 2. The locking hole 10 is provided on the epoxy baffle 2 and is used to cooperate with the screw fixing assembly to lock the installation posture of the epoxy baffle 2. When the screw 12 of the screw fixing assembly passes through the mounting hole 11 and is screwed into the threaded hole 14 in the locking hole 10, the locking hole 10 and the screw 12 cooperate with each other to restrict the position and posture of the epoxy baffle 2, keeping it in the preset installation state, thereby achieving the function of locking the installation posture of the epoxy baffle 2, and thus greatly improving the stability of the epoxy baffle 2 during operation.

[0023] An auxiliary locking mechanism is installed inside the mounting hole 11 to enhance the stability of the installation connection between the epoxy baffle 2 and the support assembly. During the operation of the screw fixing assembly, the components of the auxiliary locking mechanism act as the screw 12 is tightened. The elastic sheet 17 is pressed tightly against the inner wall of the locking hole 10 by the compression plate 16, and the wedge block 18 is embedded in the wedge groove 19, further strengthening the connection between the epoxy baffle 2 and the support assembly, thereby enhancing the connection stability between the two and greatly improving the overall structural stability of the device.

[0024] Furthermore, the locking mechanism includes a fixed cylinder 4 fixedly installed on the outer side of the first support frame 101 and the second support frame 102. The end of the fixed cylinder 4 away from the outer side of the first support frame 101 and the second support frame 102 is rotatably fitted with a locking knob 5 for driving adjustment. The inner side of the locking knob 5 is fixedly connected to an external threaded rod 6 extending axially along the fixed cylinder 4. The end of the external threaded rod 6 away from the locking knob 5 is threadedly fitted with an internal threaded rod 7 that can extend and retract axially. The end of the internal threaded rod 7 away from the external threaded rod 6 extends through to the inner side of the first support frame 101 and the second support frame 102 and is fixedly connected to a locking plate 3 for abutting and locking against the outer wall of the ship's stern pipe. The fixed cylinder 4 is provided with a limiting component for axially limiting the internal threaded rod 7. When it is necessary to lock the support assembly, turn the locking knob 5 to drive the external threaded rod 6 to rotate inside the fixed cylinder 4. Since the external threaded rod 6 is threadedly connected to the internal threaded rod 7, and the internal threaded rod 7 can only move axially under the action of the limiting assembly, the internal threaded rod 7 will drive the locking plate 3 to move towards the outer wall of the stern tube until the locking plate 3 abuts and locks against the outer wall of the stern tube, thereby achieving the effect of effectively locking the support assembly and greatly improving the firmness of the connection between the support assembly and the stern tube. Furthermore, the locking plate 3 is an arc-shaped plate adapted to the contour of the outer wall of the stern tube, and the inner wall of the locking plate 3 is provided with anti-slip textures to increase the coefficient of friction and prevent relative slippage. When the locking plate 3 abuts against the outer wall of the stern tube, the arc-shaped locking plate 3 can better fit the outer wall of the stern tube, increasing the contact area. At the same time, the anti-slip textures on the inner wall increase the friction between the locking plate 3 and the outer wall of the stern tube, preventing relative slippage between the locking plate 3 and the stern tube. This achieves the effect of enhancing the locking effect and preventing relative slippage, thereby greatly improving the locking reliability of the locking mechanism.

[0025] Furthermore, the limiting component includes limiting grooves 8 formed on both sides of the inner wall of the fixed cylinder 4. A limiting plate 9 is slidably connected inside the limiting grooves 8, and the other end of the limiting plate 9 is fixedly connected to the internal threaded rod 7. When the external threaded rod 6 rotates, the internal threaded rod 7 tends to rotate under the action of the thread. The limiting plate 9 slides in the limiting grooves 8, restricting the rotation of the internal threaded rod 7, so that the internal threaded rod 7 can only move along the axial direction. This achieves the function of axially limiting the internal threaded rod 7, thereby greatly improving the accuracy and stability of the locking mechanism adjustment.

[0026] Furthermore, the screw fixing assembly includes mounting holes 11 formed on the first support frame 101 and the second support frame 102, and threaded holes 14 formed on the side of the locking hole 10 away from the first support frame 101 and the second support frame 102 for locking. A screw 12 is threaded into the mounting hole 11 to fix the epoxy baffle 2 to the support assembly, and both ends of the screw 12 are respectively provided with external threads that are adapted to the threaded hole 14 and the mounting hole 11 to achieve double thread locking. When installing the epoxy baffle 2, the screw 12 is passed through the mounting hole 11. Since the external threads at both ends of the screw 12 are adapted to the mounting hole 11 and the threaded hole 14 respectively, when the screw 12 is tightened, the screw 12 is simultaneously threaded into the mounting hole 11 and the threaded hole 14, achieving double thread locking and fixing the epoxy baffle 2 to the support assembly. This achieves the function of double locking and fixing the epoxy baffle 2, thereby greatly improving the tightness and stability of the connection between the epoxy baffle 2 and the support assembly.

[0027] Furthermore, the auxiliary locking mechanism includes elastic plates 17 installed on both sides of the inner wall of the locking hole 10, and a sleeve 15 fitted between the threaded portions at both ends of the screw 12; each side of the sleeve 15 is fixedly connected to a pressing plate 16 for pressing the elastic plates 17 during the tightening of the screw 12. During the tightening of the screw 12, the sleeve 15 moves with the screw 12, causing the pressing plate 16 to press the elastic plates 17 on both sides of the inner wall of the locking hole 10, causing the elastic plates 17 to deform and fit tightly against the inner wall of the locking hole 10, thereby enhancing the connection strength between the epoxy baffle 2 and the support assembly, thus achieving the effect of assisting in enhancing the connection stability, and further greatly improving the stability of the epoxy baffle 2 installation.

[0028] Furthermore, multiple sets of wedge-shaped blocks 18 are fixedly connected to the side of the elastic plate 17 near the inner wall of the locking hole 10 to enhance connection stability. Multiple sets of wedge-shaped grooves 19 are formed on the inner wall of the locking hole 10 to match the wedge-shaped blocks 18. When the elastic plate 17 is compressed, the wedge-shaped blocks 18 on the elastic plate 17 embed into the wedge-shaped grooves 19 on the inner wall of the locking hole 10. Through the interlocking of the wedge-shaped structures, the movement of the elastic plate 17 is further restricted, enhancing the connection stability between the elastic plate 17 and the locking hole 10. This further enhances the connection stability and significantly improves the locking effect of the auxiliary locking mechanism.

[0029] Furthermore, four sets of locking mechanisms are provided, and these four sets are arranged in a circular array along the circumference of the first support frame 101 and the second support frame 102 to achieve a balanced locking force between the support assembly and the stern tube. When locking the support assembly, the four sets of locking mechanisms work simultaneously. Their circular array arrangement allows them to apply locking force to the support assembly from different directions, ensuring a uniform distribution of the locking force and preventing excessive or insufficient local stress. This provides a balanced locking force, thereby significantly improving the balance and stability of the connection between the support assembly and the stern tube.

[0030] Working Principle: During epoxy injection into the stern pipe of a ship, to ensure that the epoxy material does not leak before curing, an epoxy baffle device is used to securely fix and seal the sponge. During operation, the first support frame 101 and the second support frame 102 are first inserted from both sides of the stern pipe, enclosing it. The first fixing ears 103 on both sides of the first support frame 101 are aligned with the second fixing ears 104 on both sides of the second support frame 102. Fastening bolts 105 are then inserted and tightened with fastening nuts 106, achieving the initial assembly of the support components. This split design, combined with detachable bolt connections, not only facilitates device assembly while the stern pipe is already installed, but also adapts to various conditions. The need for tailpipes of different diameters enhances the versatility of the device. Then, rotating the locking knob 5 on the outer side of the fixed cylinder 4 of the support assembly drives the external threaded rod 6 to rotate within the fixed cylinder 4. Through threaded transmission, this drives the internal threaded rod 7 to move axially. Under the action of the limiting component, the limiting plate 9 slides along the limiting grooves 8 on both sides of the inner wall of the fixed cylinder 4, ensuring that the internal threaded rod 7 only performs linear motion and does not rotate with the external threaded rod 6. The internal threaded rod 7 pushes the locking plate 3 towards the outer wall of the tailpipe and finally into tight contact. The four sets of locking mechanisms arranged in a ring array can evenly apply locking force. Combined with the arc-shaped locking plate 3 adapted to the tailpipe contour and its inner wall anti-slip texture, this ensures a stable connection between the support assembly and the tailpipe. This avoids damage to the tailpipe caused by excessive local pressure, providing a stable foundation for the subsequent installation of the epoxy baffle 2. Then, the two sets of semi-circular epoxy baffles 2 are spliced ​​together to form a complete disc, conforming to the outer contour of the tailpipe. Next, screws 12 are passed through the mounting holes 11 on the support assembly and screwed into the threaded holes 14 on the side of the epoxy baffle 2 away from the support assembly, within the locking holes 10. Since the screws 12 have thread specifications matching those of the mounting holes 11 and the threaded holes 14 respectively, a double-threaded locking structure is formed, significantly improving the tightness of the connection between the epoxy baffle 2 and the support assembly. During this process, as the screws 12 are tightened, the sleeves 15 fitted between the threaded portions of the screws 12 drive the two side compression plates 16. The elastic plates 17 on both sides of the inner wall of the locking hole 10 are compressed and deformed to fit tightly against the inner wall of the locking hole 10. At the same time, multiple sets of wedge-shaped blocks 18 on the side of the elastic plate 17 closest to the inner wall of the locking hole 10 are embedded in the corresponding wedge-shaped grooves 19 on the inner wall of the locking hole 10. With the anti-loosening properties of the wedge structure, the installation stability of the epoxy baffle 2 is further enhanced, effectively preventing loosening caused by vibration during operation. At this time, the epoxy baffle 2 can reliably fix the sponge and form a sealing barrier, effectively preventing uncured epoxy from flowing out and ensuring the quality of the injection operation. The detachable nature of the entire device also makes it easy to disassemble and recycle after the operation, reducing the cost of use and improving the efficiency of operation.

[0031] Example 2 Please see Figure 1-10 This utility model provides a technical solution: a detachable epoxy baffle, comprising: A support assembly is installed outside the stern tube of the ship. The support assembly includes a first support frame 101 and a second support frame 102. The first support frame 101 has first fixing ears 103 fixedly installed on both sides for connection and fixation. The second support frame 102 has second fixing ears 104 fixedly installed on both sides corresponding to the first fixing ears 103. A fastening bolt 105 is provided between the first fixing ears 103 and the second fixing ears 104 to realize the detachable connection between the two. One end of the fastening bolt 105 is threaded with a fastening nut 106 for locking the first fixing ears 103 and the second fixing ears 104. When assembling the support assembly, the first support frame 101 and the second support frame 102 are respectively inserted from both sides of the stern tube of the ship, so that the first fixing lug 103 and the second fixing lug 104 are aligned. Then, the fastening bolt 105 is passed through the first fixing lug 103 and the second fixing lug 104, and the fastening nut 106 is tightened to connect and fix the first support frame 101 and the second support frame 102 to form a complete support assembly. This detachable connection method facilitates installation and disassembly, thereby achieving the function of convenient assembly and disassembly of the support assembly, and thus greatly improving the flexibility of the support assembly to adapt to different stern tube installation scenarios.

[0032] Epoxy baffles 2, mounted on the support assembly, are used to secure the sponge and prevent uncured epoxy from leaking out. Two sets of epoxy baffles 2 are provided, each set being semi-circular in shape. These two sets can be joined to form a complete disc structure to fit the outer contour of the ship's stern pipe. In use, the two sets of semi-circular epoxy baffles 2 are joined around the outer perimeter of the stern pipe to form a complete disc structure that fits the outer contour of the stern pipe better. This achieves a precise fit to the stern pipe's outer contour, significantly improving the securing effect of the epoxy baffles 2 on the sponge and preventing epoxy leakage.

[0033] The locking mechanism, installed on the support assembly, is used to lock and fix the support assembly to maintain its installation position. After the support assembly is installed in place, rotating the locking knob 5 causes the external threaded rod 6 to rotate inside the fixed cylinder 4. This causes the external threaded rod 6 to drive the internal threaded rod 7 to rotate, which in turn causes the internal threaded rod 7 to drive the locking plate 3 to move towards the outer wall of the stern tube. Finally, the locking plate 3 abuts and locks against the outer wall of the stern tube, firmly fixing the support assembly to the stern tube and keeping its installation position unchanged. This achieves the function of stabilizing and fixing the support assembly, thereby greatly improving the stability of the support assembly during operation.

[0034] A screw fixing assembly, mounted on the support assembly, is used to cooperate with the epoxy baffle 2 to achieve fixed installation of the epoxy baffle 2. When installing the epoxy baffle 2, the screws 12 of the screw fixing assembly pass through the mounting holes 11 on the support assembly and are tightened in cooperation with the threaded holes 14 on the epoxy baffle 2, so that the epoxy baffle 2 is tightly connected to the support assembly, thereby achieving the fixed installation of the epoxy baffle 2. This achieves the function of firmly installing the epoxy baffle 2 on the support assembly, and thus greatly improves the installation firmness of the epoxy baffle 2.

[0035] The locking hole 10 is provided on the epoxy baffle 2 and is used to cooperate with the screw fixing assembly to lock the installation posture of the epoxy baffle 2. When the screw 12 of the screw fixing assembly passes through the mounting hole 11 and is screwed into the threaded hole 14 in the locking hole 10, the locking hole 10 and the screw 12 cooperate with each other to restrict the position and posture of the epoxy baffle 2, keeping it in the preset installation state, thereby achieving the function of locking the installation posture of the epoxy baffle 2, and thus greatly improving the stability of the epoxy baffle 2 during operation.

[0036] Furthermore, the locking mechanism includes a fixed cylinder 4 fixedly installed on the outer side of the first support frame 101 and the second support frame 102. The end of the fixed cylinder 4 away from the outer side of the first support frame 101 and the second support frame 102 is rotatably fitted with a locking knob 5 for driving adjustment. The inner side of the locking knob 5 is fixedly connected to an external threaded rod 6 extending axially along the fixed cylinder 4. The end of the external threaded rod 6 away from the locking knob 5 is threadedly fitted with an internal threaded rod 7 that can extend and retract axially. The end of the internal threaded rod 7 away from the external threaded rod 6 extends through to the inner side of the first support frame 101 and the second support frame 102 and is fixedly connected to a locking plate 3 for abutting and locking against the outer wall of the ship's stern pipe. The fixed cylinder 4 is provided with a limiting component for axially limiting the internal threaded rod 7. When it is necessary to lock the support assembly, turn the locking knob 5 to drive the external threaded rod 6 to rotate inside the fixed cylinder 4. Since the external threaded rod 6 is threadedly connected to the internal threaded rod 7, and the internal threaded rod 7 can only move axially under the action of the limiting assembly, the internal threaded rod 7 will drive the locking plate 3 to move towards the outer wall of the stern tube until the locking plate 3 abuts and locks against the outer wall of the stern tube, thereby achieving the effect of effectively locking the support assembly and greatly improving the firmness of the connection between the support assembly and the stern tube.

[0037] Furthermore, the locking plate 3 is an arc-shaped plate adapted to the contour of the outer wall of the stern tube, and the inner wall of the locking plate 3 is provided with anti-slip textures to increase the coefficient of friction and prevent relative slippage. When the locking plate 3 abuts against the outer wall of the stern tube, the arc-shaped locking plate 3 can better fit the outer wall of the stern tube, increasing the contact area. At the same time, the anti-slip textures on the inner wall increase the friction between the locking plate 3 and the outer wall of the stern tube, preventing relative slippage between the locking plate 3 and the stern tube. This achieves the effect of enhancing the locking effect and preventing relative slippage, thereby greatly improving the locking reliability of the locking mechanism.

[0038] Furthermore, the limiting component includes limiting grooves 8 formed on both sides of the inner wall of the fixed cylinder 4. A limiting plate 9 is slidably connected inside the limiting grooves 8, and the other end of the limiting plate 9 is fixedly connected to the internal threaded rod 7. When the external threaded rod 6 rotates, the internal threaded rod 7 tends to rotate under the action of the thread. The limiting plate 9 slides in the limiting grooves 8, restricting the rotation of the internal threaded rod 7, so that the internal threaded rod 7 can only move along the axial direction. This achieves the function of axially limiting the internal threaded rod 7, thereby greatly improving the accuracy and stability of the locking mechanism adjustment.

[0039] Furthermore, the screw fixing assembly includes mounting holes 11 formed on the first support frame 101 and the second support frame 102, and threaded holes 14 formed on the side of the locking hole 10 away from the first support frame 101 and the second support frame 102 for locking. A screw 12 is threaded into the mounting hole 11 to fix the epoxy baffle 2 to the support assembly, and both ends of the screw 12 are respectively provided with external threads that are adapted to the threaded hole 14 and the mounting hole 11 to achieve double thread locking. When installing the epoxy baffle 2, the screw 12 is passed through the mounting hole 11. Since the external threads at both ends of the screw 12 are adapted to the mounting hole 11 and the threaded hole 14 respectively, when the screw 12 is tightened, the screw 12 is simultaneously threaded into the mounting hole 11 and the threaded hole 14, achieving double thread locking and fixing the epoxy baffle 2 to the support assembly. This achieves the function of double locking and fixing the epoxy baffle 2, thereby greatly improving the tightness and stability of the connection between the epoxy baffle 2 and the support assembly.

[0040] Furthermore, four sets of locking mechanisms are provided, and these four sets are arranged in a circular array along the circumference of the first support frame 101 and the second support frame 102 to achieve a balanced locking force between the support assembly and the stern tube. When locking the support assembly, the four sets of locking mechanisms work simultaneously. Their circular array arrangement allows them to apply locking force to the support assembly from different directions, ensuring a uniform distribution of the locking force and preventing excessive or insufficient local stress. This provides a balanced locking force, thereby significantly improving the balance and stability of the connection between the support assembly and the stern tube.

[0041] Working principle: During epoxy injection into the stern pipe of a ship, to ensure that the epoxy material does not leak before curing, an epoxy baffle device is used to securely fix and seal the sponge. During operation, the first support frame 101 and the second support frame 102 are first inserted from both sides of the stern pipe, enclosing the stern pipe. The first fixing ears 103 on both sides of the first support frame 101 are aligned with the second fixing ears 104 on both sides of the second support frame 102. Fastening bolts 105 are then inserted and tightened with fastening nuts 106, thus achieving initial support assembly. The modular design, combined with detachable bolt connections, facilitates assembly even with the tailpipe already installed. It also adapts to tailpipes of different diameters, enhancing the device's versatility. Then, rotating the locking knob 5 on the outer side of the supporting assembly's fixed cylinder 4 drives the external threaded rod 6 to rotate within the fixed cylinder 4. This, in turn, drives the internal threaded rod 7 to move axially. Under the action of the limiting component, the limiting plate 9 slides along the limiting grooves 8 on both sides of the inner wall of the fixed cylinder 4, ensuring that the internal threaded rod 7 only performs linear motion and does not rotate with the external threaded rod 6. The threaded rod 7 pushes the locking plate 3 closer to the outer wall of the tailpipe and finally makes tight contact. The four sets of locking mechanisms arranged in a ring array can apply locking force evenly. With the arc-shaped locking plate 3 that matches the tailpipe contour and its inner anti-slip texture, it not only ensures a stable connection between the support component and the tailpipe, but also avoids damage to the tailpipe caused by excessive local pressure. This provides a stable foundation for the subsequent installation of the epoxy baffle 2. Then, the two sets of semi-circular epoxy baffles 2 are spliced ​​into a complete disc to fit the outer contour of the tailpipe. Finally, the screw 12 is passed through the mounting holes on the support component. 11. Screw the screw 12 into the threaded hole 14 on the side away from the support component in the locking hole 10 of the epoxy baffle 2. Since the two ends of the screw 12 match the thread specifications of the mounting hole 11 and the threaded hole 14 respectively, a double thread locking structure is formed, which greatly improves the tightness of the connection between the epoxy baffle 2 and the support component. At this time, the epoxy baffle 2 can reliably fix the sponge and form a sealing barrier, effectively preventing uncured epoxy from flowing out and ensuring the quality of the grouting operation. The detachable feature of the entire device also makes it easy to disassemble and recycle after the operation, reducing the cost of use and improving the efficiency of operation.
