Description
Technical Field
[0001] This utility model relates to the field of buoy technology, specifically to an adjustable buoyancy drifting buoy. Background Technology
[0002] A buoy is a navigational aid that floats on the water's surface. It is anchored in a designated location to mark the extent of a navigation channel, indicate shoals, obstructions, or indicate specific navigational aids. Buoys are the most numerous and widely used type of navigational aid. They are placed in locations where it is difficult or unsuitable to establish fixed navigational aids. The function of a buoy is to mark shallow waters or obstacles that endanger navigational safety.
[0003] In operation, existing buoys typically have counterweights at the bottom of the float to increase the stability of surface drifting buoys. While this can prevent them from being overturned or capsized by wind and waves, the weight of the counterweights is mostly fixed. When the wind and waves are large, the stability provided by the counterweights is limited. Furthermore, the float's upper buoy is directly exposed to the external environment. When it encounters hard objects such as rocks or ships, it comes into direct contact with the outer shell of the float, causing damage and resulting in high maintenance costs. Utility Model Content
[0004] To address the problem that counterweights, which are mostly fixed to the buoy and directly exposed to the external environment, are easily damaged when they come into direct contact with the buoy shell when encountering hard objects such as rocks or ships, the purpose of this utility model is to provide an adjustable buoyancy drifting buoy.
[0005] To solve the above technical problems, the present invention adopts the following technical solution: an adjustable buoyancy drifting buoy, including a float body, a fixing frame on the float body, a fixing rod fixedly provided on the lower surface of the float body, a counterweight block installed at the lower end of the fixing rod, and a replacement component provided on the counterweight block and the fixing rod; The replacement component includes a positioning block, which is fixedly connected to the upper surface of the counterweight. A limiting hole is provided on the side of the positioning block. A positioning groove is provided at the lower end of the fixing rod. A concave groove is provided inside the fixing rod. A double-ended lead screw is rotatably mounted on the inner surface of the concave groove. A movable plate is threaded onto the outer surface of the double-ended lead screw. The movable plate slides against the inner surface of the concave groove. A limiting block is fixed on one side of the opposite face of the movable plate and is movably inserted into a limiting hole. A circular groove is provided on one side of the fixing rod. A circular block is fixed at one end of the double-ended lead screw, penetrating the circular groove. A crossbar is fixed on the inner surface of the concave groove, penetrating the movable plate. A turntable is fixedly mounted on the outer surface of the circular block. Several actuating notches are provided on the outer surface of the turntable, arranged in a circular array. A spring bolt is fixed on one side of the turntable, with its end movably inserted into the interior of the fixing frame. The outer side of the pontoon body is fitted with an anti-collision component.
[0006] Preferably, the anti-collision assembly includes a connecting ring, which is movably sleeved on the outer surface of the float body. An anti-collision ring is fixedly sleeved on the outer surface of the connecting ring. A fixing block is fixedly provided on the inner surface of the connecting ring. A fixing groove is provided on the float body. The fixing block is movably fitted with the inner surface of the fixing groove. An arc-shaped groove is provided on the float body. An arc-shaped spring is fixedly provided on the inner surface of the arc-shaped groove. An arc-shaped slider is fixedly provided at the other end of the arc-shaped spring. An arc-shaped insert is fixedly provided on one side of the arc-shaped slider. An arc-shaped insertion hole is provided on one side of the fixing block. The arc-shaped insert is movably inserted into the arc-shaped insertion hole. Two pull holes are provided on the upper surface of the arc-shaped slider.
[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model can change the buoyancy of a marine buoy by changing the weight of the counterweight, thus ensuring the stability of the buoy. When replacing or installing, only the turntable needs to be rotated.

[0017] 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.
[0018] Example: Figure 1-6 As shown, this utility model provides an adjustable buoyancy drifting buoy, including a float body 1, a fixing frame 11 on the float body 1, a fixing rod 12 fixedly on the lower surface of the float body 1, a counterweight 3 installed at the lower end of the fixing rod 12, and a replacement component 4 on the counterweight 3 and the fixing rod 12. The replacement component 4 includes a positioning block 41, which is fixedly connected to the upper surface of the counterweight 3. A limiting hole 42 is formed on the side of the positioning block 41. A positioning groove 43 is formed at the lower end of the fixing rod 12. A concave groove 44 is formed inside the fixing rod 12. A double-ended lead screw 45 is rotatably mounted on the inner surface of the concave groove 44. A movable plate 46 is threaded onto the outer surface of the double-ended lead screw 45. The movable plate 46 slides against the inner surface of the concave groove 44. A limiting block 47 is fixedly mounted on one side of the opposite side of the movable plate 46. The limiting block 47 is movably inserted into the limiting hole 42. A circular groove 5 is formed on one side of the fixing rod 12. A circular block 49 is fixedly mounted at one end of the double-ended lead screw 45, and the circular block 49 penetrates the circular groove 5. The outer surface of the circular block 49 is fixedly fitted with a turntable 51. The buoyancy of the buoy can be changed by changing the weight of the counterweight 3. The positioning block 41 on the counterweight 3 is inserted into the positioning groove 43. Then, the turntable 51 can be rotated by turning the notch 52. The double-headed screw 45 is rotated by the circular block 49, so that the two moving plates 46 fitted on its outer surface move towards the middle. The limiting block 47 is inserted into the limiting hole 42 to complete the installation and ensure the stability of the buoy. When replacing or installing, only the turntable 51 needs to be rotated. After the limiting block 47 is fully inserted into the limiting hole 42, the end of the spring bolt 53 is inserted into the hole opened in the circular groove 5 to limit the turntable 51 and prevent it from rotating under force, thus ensuring the stability of the buoy. The outer side of the float body 1 is fitted with an anti-collision component 6; A crossbar 48 is fixedly provided on the inner surface of the concave groove 44. The crossbar 48 passes through the moving plate 46 to assist the stable movement of the moving plate 46. Several actuation notches 52 are provided on the outer surface of the turntable 51, and the actuation notches 52 are distributed in a circular array on the outer surface of the turntable 51 to facilitate the rotation of the turntable 51. A spring bolt 53 is fixedly provided on one side of the turntable 51. The end of the spring bolt 53 is movably inserted into the inside of the fixing frame 11. A circular hole is provided in the circular groove 5 to cooperate with the spring bolt 53. The anti-collision component 6 includes a connecting ring 61, which is movably sleeved on the outer surface of the float body 1. An anti-collision ring 62 is fixedly sleeved on the outer surface of the connecting ring 61. The anti-collision ring 62 is made of high-strength polyurethane elastomer (TPU / CPU), which combines the elasticity of rubber with the strength of plastic, exhibiting excellent impact resistance (absorbing 30%-50% of impact energy) and outstanding weather resistance (resistant to ultraviolet radiation and salt spray corrosion). A ceramic particle or silicon-based wear-resistant coating can be added to the surface to extend its service life. A fixing block 63 is fixedly installed on the inner surface of the connecting ring 61. A fixing groove 631 is formed on the float body 1, and the fixing block 63 movably fits against the inner surface of the fixing groove 631. An arc-shaped groove 65 is formed on the float body 1, and an arc-shaped spring 66 is fixedly installed on the inner surface of the arc-shaped groove 65. The other end of the arc-shaped spring 66 is fixedly... An arc-shaped slider 67 is provided, with an arc-shaped insert 68 fixedly mounted on one side. An arc-shaped insertion hole 64 is provided on one side of the fixed block 63. The arc-shaped insert 68 is movably inserted into the arc-shaped insertion hole 64. Two pull holes 69 are provided on the upper surface of the arc-shaped slider 67 to facilitate the movement of the arc-shaped slider 67. The connecting ring 61 can be sleeved on the outer surface of the float body 1, and then the arc-shaped slider 67 can be moved through the pull holes 69 to move the arc-shaped insert 68 into the arc-shaped groove 65. Then the fixed block 63 can be placed into the fixed groove 631. After releasing the arc-shaped slider 67, the arc-shaped insert 68 is inserted into the arc-shaped insertion hole 64 by the force of the arc-shaped spring 66. In the event of a collision, it first contacts the anti-collision ring 62, which can reduce the impact force and also provide a certain degree of protection for the float body 1. It is also easy to replace when the anti-collision component 6 is damaged.
[0019] Working principle: When in use, the buoyancy of the buoy can be changed by altering the weight of the counterweight 3. The positioning block 41 on the counterweight 3 is inserted into the positioning groove 43. Then, the turntable 51 can be rotated by turning the notch 52. The double-ended screw 45 is rotated by the round block 49, thereby moving the two movable plates 46 on its outer surface towards the center. The limiting block 47 is inserted into the limiting hole 42, completing the installation and ensuring the stability of the buoy. When replacing or installing, only the turntable 51 needs to be rotated. After the limiting block 47 is fully inserted into the limiting hole 42, the end of the spring bolt 53 is inserted into the hole opened in the round groove 5, completing the limiting of the turntable 51, preventing it from rotating under force, and ensuring the stability of the buoy. Alternatively, by fitting the connecting ring 61 onto the outer surface of the float body 1, the arc-shaped slider 67 can be moved through the pull hole 69 to allow the arc-shaped insert 68 to enter the arc-shaped groove 65. Then, the fixing block 63 can be placed into the fixing groove 631. After releasing the arc-shaped slider 67, the arc-shaped insert 68 can be inserted into the arc-shaped insertion hole 64 by the force of the arc-shaped spring 66. In the event of a collision, it will first contact the anti-collision ring 62, which can reduce the impact force and also provide a certain degree of protection for the float body 1. It is also convenient to replace the anti-collision component 6 when it is damaged.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
