DETAILED DESCRIPTION
[0020] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Embodiment 1
[0022] See also Figure 1-Figure 3 The utility model provides a technical solution: a boat hook mechanism, comprising: a hull 1, an observation room 2 is fixedly arranged on the upper surface of the hull 1, transparent glass is arranged around the observation room 2 to observe the environment outside the boat, and boat hook devices 3 are installed at both ends of the hull 1. The boat hook device 3 is used to hang the iron chain 6 of the mother boat on the boat hook of the daughter boat when the daughter boat is lowered from the mother boat. The boat hook device 3 includes a foam tube 10, a connecting rod 9, a lifting rod 8, a fixing block 4, a hook assembly 5 and an iron chain 6. The fixing block 4 is fixedly installed on the upper surface of the hull 1, and the fixing block 4 is the foundation of the boat hook device 3. The hook assembly 5 is arranged on the fixing block 4. The hook assembly 5 is not only used for hanging on the iron chain 6, but also has a device to prevent it from falling off. The iron chain 6 is arranged on the top of the hook assembly 5, one end of the iron chain 6 is connected to the hook, and the other end of the iron chain 6 is connected to the equipment on the mother ship. The foam tube 10 extends into the lower surface of the hull 1 and is slidably connected thereto. The foam can float up under the action of seawater, and the foam will slide in the hull 1 during the floating process. The connecting rod 9 is fixedly installed on the upper surface of the foam tube 10. When the foam moves up, the connecting rod 9 will also move up accordingly. The lifting rod 8 is fixedly connected to the upper surface of the connecting rod 9. Similarly, the lifting rod 8 will naturally move up. When the lifting rod 8 moves up, the first inclined surface 17 and the second inclined surface 19 will contact each other.
[0023] A rectangular notch 7 is provided on the upper surface of the fixing block 4, and the rectangular notch 7 runs through both sides of the fixing block 4. The rectangular notch 7 connects the two side surfaces and one top of the fixing block 4. The hook assembly 5 includes a hook body 12 and a rope 15. The hook body 12 is divided into two parts. The upper part is configured as a hook groove 13 and its side wall. One end of the hook body 12 extends into the rectangular notch 7 and is rotatably connected thereto. A hook groove 13 is provided on the hook body 12, and the iron chain 6 is arranged in the hook groove 13. A first through hole 16 is provided on the top wall of the hook groove 13. One end of the rope 15 passes through the first through hole 16 and is fixedly connected to the iron chain 6. The other end of the rope 15 is connected to the equipment on the mother ship. This equipment has a tightening effect, and the rope 15 can be recovered at any time, and the rope 15 can be released separately.
[0024] When in use, firstly, one end of the rope 15 is passed through the first through hole 16 and fixedly connected to the iron chain 6 scraped in the hook groove 13. When the rope 15 is tightened, the iron chain 6 will be firmly stuck in the hook groove 13. Then, the lifeboat is lowered. When the lifeboat contacts the water surface, the foam board will float upward relative to the hull under the action of water and will drive the connecting rod 9 and the lifting rod 8 to move upward. During the lowering process, the rope 15 is tightened, and the rope 15 will be firmly stuck in the hook groove 13. Even if it is unhooked, the rope 15 will bear the tension of the hook, and the lifeboat will not easily capsize.
[0025] Embodiment 2
[0026] See also Figure 2-Figure 4 On the basis of the first embodiment, a first inclined surface 17 is provided on the lower surface of the hook body 12, and the first inclined surface 17 is used to ensure that the hook body 12 can be tilted to one side. One end of the lifting rod 8 penetrates the bottom wall of the rectangular notch 7 and is slidably connected thereto. One end of the lifting rod 8 extends into the rectangular notch 7 and is directly below the hook body 12 during the process of releasing the lifeboat. A second inclined surface 19 is provided on the top of the lifting rod 8, and the second inclined surface 19 is adapted to the first inclined surface 17. The second inclined surface 19 further strengthens the degree of its tilt, making the device more flexible to use. A second through hole 18 is provided on the top of the lifting rod 8, and the second through hole 18 is used to discharge gas. A third through hole 20 is provided on the side wall of the second through hole 18, and the third through hole 20 is connected to the second through hole 18. A limit block 11 is fixedly connected to one side of the hook body 12, and the limit block 11 is used to limit to ensure that the iron chain 6 slides over and is stuck between the first inclined surface 17 and the second inclined surface 19 when it slides down.
[0027] When in actual use, firstly, one end of the rope 15 is passed through the first through hole 16 and fixedly connected with the iron chain 6 scraped in the hook groove 13. When the rope 15 is tightened, the iron chain 6 will be firmly stuck in the hook groove 13. Then, the lifeboat will be lowered. When the lifeboat contacts the water surface, the foam board will float upward relative to the hull under the action of water and will drive the connecting rod 9 and the lifting rod 8 to move upward. The second through hole 18 and the third through hole 20 on the lifting rod 8 are helpful to discharge gas, and the second inclined surface 19 on the upper surface of the lifting rod 8 will contact the first inclined surface 17. Under the action of force, the hook body 12 will rotate. At this time, the side wall of the hook body 12 on one side of the hook groove 13 is in an inclined state. Then, the iron chain 6 and the other end of the rope 15 will continue to be lowered. The iron chain 6 will slide down along the hook body 12 to the limit block 11, and then the iron chain 6 will be pulled up and the rope 15 will be pulled up together for recycling and reuse.
