Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of unmanned boats, and particularly relates to an adjustable buoy assembly for an unmanned boat. Background Art
[0002] An unmanned boat is a fully automatic surface robot that can sail on the water according to a preset task without remote control, relying on precise satellite positioning and its own sensors. At present, in China, unmanned boats are mainly used in fields such as surveying and mapping, river dredging, hydrology, and water quality monitoring. Such unmanned boats mainly provide corresponding buoyancy through a buoy assembly.
[0003] For example, the Chinese patent document with the publication number CN217260595U discloses a new type of buoy for an unmanned boat, including a buoy body. The buoy body is U-shaped, and power devices are respectively arranged at both ends of the buoy body. The power device includes a propeller and a built-in motor. The whole buoy body moves away from the propeller side. A fixing plate is horizontally arranged inside the buoy body, and external buoys are symmetrically arranged on both sides of the buoy body. The external buoys are fixed to the buoy body as a whole through a connecting mechanism. One end of the external buoy is provided with a conical head, and the other end is provided with an air inlet and outlet.
[0004] In the above technical solution, by installing external buoys on both sides of the buoy body, the width of the hull can be increased, and the overall stability can be improved. However, it is found in the actual use process that after the width of the hull is increased, when the hull is used in a narrow water area, due to the increased width, the overall passability is reduced. Therefore, there are certain limitations in the scope of application. Summary of the Invention
[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an adjustable buoy assembly for an unmanned boat, which can drive the external buoy to rotate to adjust the overall water entry width of the hull.
[0006] To achieve the above purpose, the utility model provides the following technical solution: an adjustable buoy assembly for an unmanned boat, including a hull. Connecting sleeves are symmetrically and fixedly arranged on the hull. The connecting sleeves are provided with outwardly protruding connecting flanges. A rotating shaft is rotatably connected between the two connecting flanges on both sides. An external buoy that can rotate around the rotating shaft is arranged outside the hull. A driving device is arranged on the hull. The driving device is used to drive the external buoy to rotate around the rotating shaft to adjust the overall water entry width of the hull.
[0007] The utility model is further arranged as follows: a partition is arranged on the hull. An installation cavity is formed between the partition and the bottom of the hull. The driving device is arranged in the installation cavity.
[0008] The utility model is further configured as follows: a symmetrical mounting sleeve is fixedly mounted on the outer periphery of the external buoy, a connecting rod extending toward the rotating shaft is provided on the mounting sleeve, and the connecting rod is located on a side facing the rotating shaft and is mounted and fixedly mounted on the outer periphery of the rotating shaft.
[0009] The utility model is further configured as follows: the driving device includes a connecting seat symmetrically arranged in the installation cavity, a connecting shaft is rotatably connected to the connecting seat, one end of the connecting shaft is connected to a worm wheel, a bidirectional worm is rotatably connected in the installation cavity, the end of the bidirectional worm is meshed with the worm wheel, and a transmission cooperation between the two can be formed, one side of the bidirectional worm is connected to a driving motor, the driving motor is used to drive the bidirectional worm to rotate, a transmission sleeve is provided between the installation sleeves, the transmission sleeve is fixed to the outer periphery of the external buoy, a transmission rod is provided between the transmission sleeve and the connecting shaft, one end of the transmission rod is sleeved and fixed to the outer periphery of the connecting shaft, and the other end is rotatably connected to the transmission sleeve.
[0010] The utility model is further configured as follows: a connecting portion is provided inside the hull, and the partition plate is detachably connected to the connecting portion.
[0011] The utility model is further configured as follows: the partition is provided with a clearance opening for the transmission rod to pass through, and the partition is provided with a handle.
[0012] The utility model is further configured as follows: a plurality of first threaded holes are provided on the connecting portion, a second threaded hole opposite to the first threaded hole is provided on the partition plate, and the first threaded hole and the second threaded hole are fixed by a locking member.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] Since an external buoy that can rotate with a rotation axis as a rotation center is arranged on the outside of the hull, when passing through narrow waters, the external buoy is driven by the driving device to rotate with the rotation axis as the rotation center, so that the external buoy can be directed toward the hull, so that the external buoy can be away from the water surface, thereby shortening the overall water entry width of the unmanned boat in disguise. Therefore, the technical problem in the prior art that the overall water entry width of the unmanned boat is larger due to the installation of external buoys, resulting in poor overall passability when used in narrow waters, thereby making the unmanned boat adaptable to more waters and expanding the scope of application. When the unmanned boat is used in wider waters, the external buoy can be driven by the driving device to rotate with the rotation axis as the rotation center, so that the external buoy can be away from the hull, so that the external buoy can re-enter the water, thereby increasing the overall water entry width of the unmanned boat in disguise, thereby improving the overall stability of the unmanned boat.

[0020] like Figures 1 to 3 As shown, the utility model discloses an adjustable buoy assembly for an unmanned boat, including a hull 1, a connecting sleeve 2 is symmetrically fixed on the hull 1, a connecting flange 21 protruding outward is provided on the connecting sleeve 2, a rotating shaft 3 is rotatably connected between the connecting flanges 21 on both sides, an external buoy 4 which can rotate with the rotating shaft 3 as the rotating center is provided on the outer side of the hull 1, and a driving device is provided on the hull 1, and the driving device is used to drive the external buoy 4 to rotate with the rotating shaft 3 as the rotating center, so as to adjust the overall water entry width of the hull 1. When passing through narrow waters, the external buoy 4 is driven by the driving device By rotating with the shaft 3 as the center of rotation, the external buoy 4 can be directed toward the hull 1, so that the external buoy 4 can be away from the water surface, thereby shortening the overall water entry width of the unmanned boat in disguise, thereby making the unmanned boat adaptable to more waters and expanding the scope of application. When the unmanned boat is used in wider waters, the external buoy 4 can be driven by the driving device to rotate with the shaft 3 as the center of rotation, so that the external buoy 4 can be away from the hull 1, so that the external buoy 4 can re-enter the water, thereby increasing the overall water entry width of the unmanned boat in disguise, thereby improving the overall stability of the unmanned boat.
[0021] In this embodiment, a partition 5 is further provided on the hull 1. An installation cavity 6 is formed between the partition 5 and the bottom of the hull 1. The driving device is arranged in the installation cavity 6. Through the arrangement of the partition 5, an installation cavity 6 can be formed between the partition 5 and the hull 1, so that the driving device can be arranged in the installation cavity 6, thereby ensuring that the installation of the driving device does not affect the cargo-loading area of the hull 1.
[0022] In this embodiment, the connection structure of the external floating cylinder 4 is as follows: Symmetric installation sleeves 7 are fixedly sleeved on the outer periphery of the external floating cylinder 4. The installation sleeves 7 are provided with connecting rods 71 extending towards the rotating shaft 3. The connecting rods 71 are fixedly sleeved on the outer periphery of the rotating shaft 3 on the side facing the rotating shaft 3. In this way, by sleeving the connecting rods 71 on the rotating shaft 3, the connecting rods 71 can drive the external floating cylinder 4 to rotate around the rotating shaft 3.
[0023] In this embodiment, the specific structure of the driving device includes connection seats 81 symmetrically arranged in the installation cavity 6. A connection shaft 82 is rotatably connected to the connection seats 81. One end of the connection shaft 82 is connected with a worm wheel 83. A two-way worm 84 is rotatably connected in the installation cavity 6. The end of the two-way worm 84 meshes with the worm wheel 83, and a transmission cooperation can be formed between the two.

One end of the transmission rod 87 is fixedly sleeved on the outer periphery of the connection shaft 82, and the other end is rotatably connected to the transmission sleeve 86. When it is necessary to drive the external floating cylinder 4 to rotate around the rotating shaft 3, the driving motor 85 drives the two-way worm 84 to rotate. Since the two side ends of the two-way worm 84 are symmetric worm parts respectively, the two-way worm 84 can mesh with the worm wheels 83 on both sides. After the two-way worm 84 rotates, it can drive the worm wheel 83 to rotate, thereby driving the connection shaft 82 to rotate. As the connection shaft 82 rotates, the transmission rod 87 can drive the external floating cylinder 4 to rotate, so that the external floating cylinder 4 can move away from the water surface (shortening the overall water entry width of the unmanned ship) or re-enter the water (increasing the overall water entry width of the unmanned ship).
[0024] In this embodiment, the connection structure of the partition 5 is as follows: A connection part 9 is provided inside the hull 1, and the partition 5 is detachably connected to the connection part 9. In addition, a relief opening 51 for the transmission rod 87 to pass through is provided on the partition 5 to prevent interference with the rotation of the transmission rod 87 when the transmission rod 87 rotates with the connection shaft 82. And a handle 52 is provided on the partition 5. Through the handle 52, force can be applied conveniently, so as to facilitate the disassembly and assembly of the partition 5.
[0025] Among them, the detachable connection structure between the partition plate 5 and the hull 1 is that a plurality of first threaded holes 91 are provided on the connecting portion 9, and second threaded holes 53 opposite to the first threaded holes 91 are provided on the partition plate 5. The first threaded holes 91 and the second threaded holes 53 are fixed by locking members. In this way, by screwing the locking members that can form a threaded fit with the first threaded holes 91 and the second threaded holes 53 into or out of the first threaded holes 91 and the second threaded holes 53, the fixing or disassembling of the partition plate 5 can be realized.
