[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3 A quick-change hose interface for a high-flow-rate fire extinguishing robot for ships includes a first water pipe 1, with a connecting pipe 18 connected to the top of the first water pipe 1. The outer wall of the connecting pipe 18 has a first external thread. A support ring 11 is placed around the outer ring of the first water pipe 1. Threaded holes are evenly distributed through the outer wall of the support ring 11. A second water pipe 14 is placed inside the threaded holes. The outer wall of the second water pipe 14 has a second external thread, which is screwed into the threaded holes. A hose interface 15 is connected to the top of the second water pipe 14. A connecting sleeve 17 is fixedly installed around the outer ring of the second water pipe 14. The inner wall of the connecting sleeve 17 has a... The device has an internal thread that corresponds to the first external thread of the connecting pipe 18. Two sets of limiting rings 2 are evenly fixedly arranged on the outer ring of the first water pipe 1. An annular limiting groove is formed on the outer wall of the limiting ring 2. A support plate 12 is evenly fixedly arranged on the inner wall of the support ring 11. The side of the support plate 12 away from the support ring 11 is slidably disposed within the annular limiting groove. The support plate 12 assists the support ring 11 in stable rotation. A flange 19 is connected to the rear side of the first water pipe 1. The flange 19 is connected to the water inlet flange of the high-flow-rate fire extinguishing robot for ships using bolts and nuts, thus completing the installation of the device. A second sealing ring 22 is fixedly installed on the outer ring of the water pipe 14. A first sealing ring 21 is fixedly installed on the top of the inner wall of the connecting sleeve 17. The bottom of the first sealing ring 21 corresponds to the top of the connecting pipe 18. The outer wall of the second sealing ring 22 corresponds to the inner wall of the connecting pipe 18. The front side of the support ring 11 is uniformly printed with model and size markings 16. The model and size markings 16 can help users quickly identify the model and size of the hose connector 15. Then, by rotating the support ring 11, the hose connector 15 is rotated on the outer ring of the first water pipe 1. When the hose connector 15 to be used moves to the connecting pipe 1... When the second water pipe 14 is directly above the support ring 11, rotate the second water pipe 14 downwards through the threaded hole of the support ring 11. When the second water pipe 14 moves downwards, it causes the connecting sleeve 17 to be fitted onto the outside of the connecting pipe 18. By continuing to rotate the second water pipe 14, the internal thread of the connecting sleeve 17 is screwed into the first external thread of the connecting pipe 18. When the connecting sleeve 17 is tightened onto the connecting pipe 18, the bottom of the first sealing ring 21 will fit tightly against the top of the connecting pipe 18, and the outer wall of the second sealing ring 22 will fit tightly against the inner wall of the connecting pipe 18. The model size marking 16 corresponds to the water hose interface 15. Figure 1The four sets of model size markings 16 on the front side of the support ring 11 shown are DN40, DN50, DN65 and DN80 respectively.

[0020] Positioning rings 13 are uniformly fixed on the outer wall of the support ring 11. The positioning rings 13 are located on the outer ring of the second water pipe 14. A set of mounting holes are opened on both the front and rear sides of the inner side wall of the positioning ring 13. A spring 23 is fixedly installed in the mounting hole. A round-headed pin 24 is fixedly installed on the outer side of the spring 23. A set of positioning holes are opened on both the front and rear sides of the second water pipe 14. A magnet 25 is fixedly installed in the positioning hole. When the connecting sleeve 17 is tightened on the connecting pipe 18, the spring 23 uses its own rebound force to drive the round-headed part of the round-headed pin 24 to be inserted into the positioning hole of the second water pipe 14. The round-headed part of the round-headed pin 24 is magnetically attracted by the magnet 25. The round-headed part of the round-headed pin 24 corresponds to the positioning hole and the magnet 25.

[0021] Working principle: The flange 19 is connected to the water inlet flange of the high-flow-rate fire extinguishing robot for ships using bolts and nuts, thus completing the installation of the device. The model and size marking 16 helps the user quickly identify the model and size of the hose connector 15. Then, by rotating the support ring 11, the hose connector 15 is rotated to rotate the outer ring of the first water pipe 1. When the hose connector 15 to be used is moved directly above the connecting pipe 18, the second water pipe 14 is rotated, causing it to rotate downward through the threaded hole of the support ring 11. When the second water pipe 14 moves downward, it causes the connecting sleeve 17 to be sleeved on the outside of the connecting pipe 18, thus opening the fire hose. By continuing to rotate the second water pipe 14, the internal thread of the connecting sleeve 17 is screwed into the first external thread of the connecting pipe 18, thereby connecting the second water pipe 14 and the connecting pipe 18 through the connecting sleeve 17. When the connecting sleeve 17 is tightened on the connecting pipe 18, the bottom of the first sealing ring 21 will fit tightly against the top of the connecting pipe 18, and the outer wall of the second sealing ring 22 will fit tightly against the inner wall of the connecting pipe 18. Thus, the second sealing ring 22 seals the connection gap between the second water pipe 14 and the connecting pipe 18, and the first sealing ring 21 seals the connection gap between the connecting sleeve 17 and the connecting pipe 18.

[0022] When the connecting sleeve 17 is tightened onto the connecting pipe 18, the spring 23 uses its own rebound force to drive the round head of the round head pin 24 to be inserted into the positioning hole of the second water pipe 14. In this way, the second water pipe 14 is positioned by the round head pin 24, thereby improving the connection stability between the second water pipe 14 and the connecting pipe 18. Furthermore, the round head of the round head pin 24 is magnetically attracted by the magnetic block 25, thereby improving the insertion stability of the round head pin 24 and ensuring the reliability of the device.
