Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydrological surveying and mapping, and in particular to an unmanned vessel for hydrological surveying and mapping. Background Technology
[0002] An existing patent (publication number: CN222432555U) proposes an unmanned surface vessel (USV) for hydrographic surveying, including a hull. A support frame is installed at the front end of the hull, and a support plate is welded to the top of the support frame. A guide tube is fixedly installed on the support plate, and a support column is slidably connected inside the guide tube. The support frame is equipped with an anti-collision mechanism through the support plate and the support column to protect the front end of the hull from running aground. However, this device states that "when the hull is hit by a collision, the strong spring is impacted, and the support column contracts into the guide tube, squeezing the strong spring. The tension of the strong spring itself can support the support column in the opposite direction, thus mitigating the impact." After being squeezed, the spring will relax, thereby quickly pushing the support column and guide tube back. This may cause the anti-collision frame to make secondary contact with the obstacle, resulting in a secondary impact on the hull and affecting the safety of the hull during surveying. Summary of the Invention
[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a hydrographic unmanned surface vessel (USV) that reduces the rotational speed of the slow-rotating cylinder by utilizing the frictional force between the slow-rotating cylinder and the auxiliary mounting groove, and the frictional force between the slow-rotating cylinder mounting ring and the slow-rotating cylinder mounting groove. This reduces the secondary impact on the USV body caused by the collision between the buffer protective plate and obstacles during the retraction of the buffer spring, thereby further ensuring the safety of the USV body during surveying.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] An unmanned surface vessel (USV) for hydrological surveying includes a USV body, a slow-rotating cylinder, a buffer protective plate, a buffer spring, a protective plate docking block, a slow-rotating cylinder docking block, an inner rotating rod, and a pawl block. The USV body has a protective plate mounting platform on its forward-facing side. A buffer protective plate is installed on the side of the USV body. A protective plate mounting post is located on the side of the buffer protective plate facing the USV body. A protective plate positioning rod is located on the side of the protective plate mounting post facing the USV body. The positioning rod is adapted to the protective plate mounting platform and connected to the platform. The protective plate slides inside the mounting platform. A buffer spring is sleeved on the outside of the positioning rod of the protective plate. One side of the buffer spring is connected to the mounting column of the protective plate, and the other side of the buffer spring is connected to the mounting platform of the protective plate. The side of the buffer protective plate away from the direction of travel of the unmanned vessel body has a protective plate docking platform. The protective plate docking platform has a protective plate docking groove inside. A protective plate docking block is set on the side of the protective plate docking platform. A protective plate docking column is located in the middle of the protective plate docking block. The protective plate docking column is adapted to the protective plate docking groove and is connected to the protective plate docking groove. The protective plate docking column rotates inside the protective plate docking groove.
[0006] The bottom of the protective plate docking block has a docking block linkage rod, and the bottom of the protective plate docking block is provided with a retarder docking block. The retarder docking block has docking block linkage grooves on both sides. The docking block linkage rod is adapted to the docking block linkage groove and is connected to the docking block linkage groove. The docking block linkage rod slides inside the docking block linkage groove. The unmanned vessel body has retarder mounting platforms on both sides. The retarder mounting platforms are located on the side of the protective plate docking block away from the buffer protective plate. The retarder mounting platform has a rotating rod connecting groove inside. The rotating rod connecting groove is adapted to the inner rotating rod and is connected to the inner rotating rod. The inner rotating rod slides inside the rotating rod connecting groove. The inner rotating rod has a hexagonal positioning groove inside. The side of the retarder docking block facing the retarder mounting platform has a hexagonal sliding rod.
[0007] The hexagonal slide bar is adapted to the hexagonal positioning groove. The hexagonal slide bar is connected to the hexagonal positioning groove and slides inside the hexagonal positioning groove. The side of the retarder mounting platform away from the buffer protection plate has a retarder mounting ring. A retarder rotating cylinder is provided on the outside of the retarder mounting ring. The retarder rotating cylinder has a ratchet inside. The side of the ratchet facing the retarder mounting ring has a retarder mounting groove. The retarder mounting ring is adapted to the retarder mounting groove and is connected to the retarder mounting groove. The retarder mounting groove rotates outside the retarder mounting ring. A ratchet block is provided inside the ratchet.
[0008] Beneficial effects: 1. After a collision, the buffer spring needs to change from a compressed state to a relaxed state due to its own properties. At this time, the buffer spring drives the buffer protection plate away from the unmanned vessel body. During this process, the inner rotating rod drives the pawl block to rotate in the opposite direction. At this time, the pawl block drives the slow rotating cylinder to rotate synchronously. Through the friction between the slow rotating cylinder and the auxiliary mounting groove, and the friction between the slow rotating cylinder mounting ring and the slow rotating cylinder mounting groove, the rotation speed of the slow rotating cylinder itself is reduced, thereby slowing down the rebound process of the buffer spring. This prevents the buffer protection plate from contracting and rebounding rapidly after a collision, thereby reducing the secondary impact of the buffer protection plate colliding with the obstacle during the buffer spring's retraction process on the unmanned vessel body, and further ensuring the safety of the unmanned vessel body during surveying.
[0009] 2. During hydrological surveying using this unmanned surface vessel (USV), a buffer spring is installed between the USV body and the buffer protection plate. This buffer spring partially cushions the impact when the buffer protection plate collides with the USV body. Simultaneously, as the buffer protection plate approaches the USV body, it drives the inner rotating rod to rotate forward inside the slow-moving rotating cylinder. At this time, the pawl block only slides inside the ratchet gear, thus ensuring that the rotation of the inner rotating rod is not obstructed. This allows the buffer spring to respond quickly and stably during the buffering process, preventing a large amount of impact from the buffer protection plate from being transmitted to the USV body and thus avoiding damage to the USV body, thereby ensuring the surveying safety of the USV body.
[0010] 3. The surface of the slow-rotating cylinder of this utility model is patterned, which increases the friction of the surface of the slow-rotating cylinder, so that the rotation speed of the slow-rotating cylinder is lower when it rotates inside the auxiliary mounting groove, thereby further increasing the effect of slow rebound of the buffer protective plate.
[0011] 4. The rear of the retarder auxiliary platform of this utility model is designed with an inclined surface, so that the overall protective device composed of buffer protection plate, retarder mounting platform, retarder rotating cylinder and retarder auxiliary platform is streamlined. This prevents the rear of the retarder auxiliary platform from generating a large amount of turbulence during the forward movement of the unmanned vessel, reduces the resistance during the forward movement of the unmanned vessel, thereby reducing the power consumption of the unmanned vessel and increasing the overall range of the unmanned vessel.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
[0021] Example 1:
[0022] An unmanned surface vessel (USV) for hydrological surveying includes a USV body 1, a slow-rotating cylinder 3, a buffer protective plate 5, a buffer spring 9, a protective plate docking block 14, a slow-rotating cylinder docking block 17, an inner rotating rod 20, and a pawl block 26. The USV body 1 has a protective plate mounting platform 6 on its side facing the forward direction. A buffer protective plate 5 is provided on the side of the USV body 1. A protective plate mounting post 7 is located on the side of the buffer protective plate 5 facing the USV body 1. A protective plate positioning rod 8 is located on the side of the protective plate mounting post 7 facing the USV body 1. The protective plate positioning rod 8 is adapted to the protective plate mounting platform 6 and is connected to the protective plate mounting platform 6. The protective plate positioning rod 8 slides inside the protective plate mounting platform 6. The buffer spring 9 is sleeved on the outside of the positioning rod 8 of the protective plate. Through the buffer spring 9 installed between the unmanned vessel body 1 and the buffer protective plate 5, the buffer spring 9 can partially buffer the impact when the buffer protective plate 5 collides. Simultaneously, as the buffer protective plate 5 approaches the unmanned vessel body 1, it drives the inner rotating rod 20 to rotate forward inside the slow-moving rotating cylinder 3. At this time, the pawl block 26 only slides inside the ratchet gear 23, thus ensuring that the rotation of the inner rotating rod 20 is not obstructed. This allows the buffer spring 9 to respond quickly and stably during the buffering process, preventing a large amount of impact from the buffer protective plate 5 from being transmitted to the unmanned vessel body 1 and damaging it, thus ensuring the surveying safety of the unmanned vessel body 1. One side of the buffer spring 9 is connected to the protective plate mounting post 7, and the other side is connected to the protective plate mounting platform 6. After a collision, the buffer spring 9 needs to change from a compressed state to a relaxed state due to its own properties. At this time, the buffer spring 9 drives the buffer protective plate 5 away from the unmanned vessel body 1. During this process, the inner rotating rod 20 drives the pawl block 26 to rotate in the opposite direction. At this time, the pawl block 26 drives the slow rotating cylinder 3 to rotate synchronously. Through the friction between the slow rotating cylinder 3 and the auxiliary mounting groove 24, and the friction between the slow cylinder mounting ring 21 and the slow cylinder mounting groove 22, the rotation speed of the slow rotating cylinder 3 is reduced, thereby slowing down the rebound process of the buffer spring 9, so that the buffer protective plate 5 will not rebound rapidly after being impacted. The system contracts and rebounds quickly, thereby reducing the secondary impact of the buffer protective plate 5 colliding with obstacles during the retraction of the buffer spring 9 on the unmanned vessel body 1, further ensuring the safety of the unmanned vessel body 1 during surveying. The buffer protective plate 5 has a protective plate docking platform 11 on the side away from the forward direction of the unmanned vessel body 1. The protective plate docking platform 11 has a protective plate docking groove 12 inside. A protective plate docking block 14 is provided on the side of the protective plate docking platform 11. A protective plate docking post 13 is provided in the middle of the protective plate docking block 14. The protective plate docking post 13 is adapted to the protective plate docking groove 12. The protective plate docking post 13 is connected to the protective plate docking groove 12 and rotates inside the protective plate docking groove 12.
[0023] Example 2:
[0024] The protective plate docking block 14 of this utility model has a docking block linkage rod 15 at its bottom and a retarder docking block 17 at its bottom.

The docking block linkage rod 15 is adapted to the docking block linkage grooves 16 and is connected to the docking block linkage grooves 16. The docking block linkage rod 15 slides inside the docking block linkage grooves 16. The unmanned vessel body 1 has retarder mounting platforms 4 on both sides. The retarder mounting platforms 4 are located on the side of the protective plate docking block 14 away from the buffer protective plate 5. The retarder mounting platform 4 has a rotating rod connecting groove 19 inside. The rotating rod connecting groove 19 is adapted to the inner rotating rod 20 and is connected to the inner rotating rod 20. The inner rotating rod 20 slides inside the rotating rod connecting groove 19. The inner rotating rod 20 has a hexagonal positioning groove 28 inside. The retarder docking block 17 has a hexagonal sliding rod 18 on the side facing the retarder mounting platform 4.
[0025] Example 3:
[0026] The hexagonal slide rod 18 of this utility model is adapted to the hexagonal positioning groove 28. The hexagonal slide rod 18 is connected to the hexagonal positioning groove 28 and slides inside the hexagonal positioning groove 28. The deceleration cylinder mounting platform 4 has a deceleration cylinder mounting ring 21 on the side away from the buffer protection plate 5. A deceleration rotating cylinder 3 is provided on the outside of the deceleration cylinder mounting ring 21. The surface of the deceleration rotating cylinder 3 is patterned to increase the friction of the surface of the deceleration rotating cylinder 3, thereby enabling the deceleration rotating cylinder 3 to assist in the mounting process. The rotation speed inside the groove 24 is lower, thereby further increasing the effect of the slow rebound of the buffer protection plate 5. The slow rotating cylinder 3 has a ratchet 23 inside. The ratchet 23 has a slow cylinder mounting groove 22 on the side facing the slow cylinder mounting ring 21. The slow cylinder mounting ring 21 is adapted to the slow cylinder mounting groove 22. The slow cylinder mounting ring 21 is connected to the slow cylinder mounting groove 22. The slow cylinder mounting groove 22 rotates outside the slow cylinder mounting ring 21. The ratchet 23 is provided with a pawl block 26 inside.
[0027] Example 4:
[0028] The ratchet block 26 of this utility model has a ratchet block mounting post 25 at its bottom and a ratchet block mounting groove 27 on the surface of the inner rotating rod 20. The ratchet block mounting post 25 is adapted to the ratchet block mounting groove 27 and is connected to the ratchet block mounting groove 27. The ratchet block mounting post 25 slides inside the ratchet block mounting groove 27 and is connected to the ratchet block mounting groove 27 by a spring. The ratchet block 26 meshes with the ratchet gear 23.
[0029] Example 5:
[0030] The unmanned surface vessel (USV) described in this invention has retarder auxiliary platforms 2 on both sides of its main body 1. The rear of the retarder auxiliary platform 2 is designed with an inclined surface, making the overall protective device composed of the buffer protection plate 5, retarder mounting platform 4, retarder rotating cylinder 3, and retarder auxiliary platform 2 streamlined. This prevents the retarder auxiliary platform 2 from generating a large amount of turbulence during the forward movement of the USV, reducing the resistance of the USV and thus reducing the power consumption of the USV and increasing the overall range of the USV. The retarder auxiliary platform 2 is located on the side of the retarder mounting platform 4 away from the buffer protection plate 5. The retarder auxiliary platform 2 has an auxiliary mounting groove 24 inside, which is adapted to the retarder rotating cylinder 3. The auxiliary mounting groove 24 is connected to the retarder rotating cylinder 3, and the retarder rotating cylinder 3 rotates inside the auxiliary mounting groove 24.
