Description

Technical Field

[0001] This utility model relates to the field of buoy counterweights, and in particular to a deep-sea buoy counterweight structure. Background Technology

[0002] In fields such as deep-sea resource exploration, marine environmental monitoring, and meteorological data acquisition, buoys serve as crucial marine observation platforms, and their stable operation directly depends on a well-designed counterweight system. Deep-sea areas are characterized by high water pressure, complex currents, and harsh environments. Buoys must precisely adjust their center of gravity and buoyancy balance through a counterweight structure to ensure they maintain their preset observation attitude even under extreme conditions such as strong currents and large waves. This avoids the risk of capsizing due to a shift in the center of gravity or drifting of the observation position due to buoyancy imbalance.

[0003] Currently, most deep-sea buoy counterweight structures employ fixed counterweight blocks and bolted connections, or utilize hydraulically driven counterweight chamber lifting technology for counterweight adjustment. In the fixed counterweight scheme, technicians pre-install several metal counterweight blocks at the bottom of the buoy or in specific chambers, based on the buoy's designed buoyancy and preset center of gravity position. These counterweight blocks are rigidly connected to the buoy body via multiple high-strength bolts. By increasing or decreasing the number of counterweight blocks or replacing them with different weights, the overall counterweight of the buoy can be adjusted. In the hydraulically driven scheme, an independent counterweight chamber is installed inside the buoy, filled with counterweight media such as sand, gravel, and metal particles. The vertical movement of the counterweight chamber within the buoy is controlled by hydraulic cylinders, changing the center of gravity position of the chamber and indirectly adjusting the buoy's overall center of gravity and buoyancy characteristics to adapt to observation needs under different sea conditions.

[0004] Existing technologies generally lack efficient and rapid configuration mechanisms for adjusting the buoy weight in deep-sea operations. This problem is particularly prominent in deep-sea environments, directly making it difficult to adjust the buoy's center of gravity or buoyancy characteristics. Taking the fixed counterweight scheme as an example, if the buoy weight needs to be adjusted during offshore operations, technicians must first use specialized equipment to lift or retrieve the buoy to the deck, and then use wrenches, screwdrivers, and other tools to disassemble the bolts fixing the counterweight one by one. After replacing or adding or removing the counterweight, the bolts are tightened again. The entire process not only consumes a lot of manpower and time, but also poses safety hazards in the deep-sea environment with large waves and limited deck working space. During bolt disassembly and installation, tools may fall or counterweights may slip, making it difficult to efficiently advance the weight adjustment work. Even with a hydraulically driven counterweight tank design, the response speed of the hydraulic system is greatly affected by the low temperature and high pressure environment of the deep sea. The extension and retraction speed of the hydraulic cylinders will be significantly reduced, and the position adjustment cycle of the counterweight tank will be greatly extended. This makes it impossible to quickly respond to the emergency adjustment needs of the buoy's center of gravity and buoyancy characteristics under sudden sea conditions, which in turn affects the buoy's observation stability and data acquisition accuracy. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a deep-sea buoy counterweight structure, which aims to improve the problem that the lack of a rapid configuration mechanism means that adjusting the buoy's center of gravity or buoyancy characteristics will become difficult in the deep-sea environment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a deep-sea buoy counterweight structure, comprising a first hollow column, a first mast fixedly connected to the bottom of the first hollow column, a battery fixedly connected to the bottom of the first mast, a counterweight block slidably connected to the outer wall of the first mast, and a buckle assembly provided on the outer wall of the counterweight block; The buckle assembly includes a support plate, the side wall of which is fixedly connected to the outer wall of the counterweight. A rotating shaft is rotatably connected to the inner wall of the support plate. A rotating plate is rotatably connected to the outer wall of the rotating shaft. A rotating column is rotatably connected inside the rotating plate. A sliding rod is slidably connected inside the rotating column. A retaining ring is fixedly connected to one end of the sliding rod. A retaining block is slidably connected inside the retaining ring. The side wall of the retaining block is fixedly connected to the outer wall of the counterweight.

[0007] As a further description of the above technical solution: A second hollow column is fixedly connected to the top of the first hollow column, and a sealing disc is slidably connected to the top of the second hollow column. Horizontal floats are fixedly connected to the outer walls of both the first and second hollow columns.

[0008] As a further description of the above technical solution: A second mast is fixedly connected to the top of the sealing disc, a second antenna is fixedly connected to the top of the second mast, and multiple first antennas are fixedly connected to the outer wall of the second mast.

[0009] As a further description of the above technical solution: A second clamping claw is fixedly connected to the outer wall of the sealing disc, and a second clamping plate is fixedly connected to the outer wall of the sealing disc.

[0010] As a further description of the above technical solution: The outer wall of the second hollow column is fixedly connected to a first clamping plate, and the outer wall of the second hollow column is fixedly connected to a first clamping claw.

[0011] As a further description of the above technical solution: The inner wall of the first claw is rotatably connected to the outer wall of the second card plate, and the inner wall of the second claw is rotatably connected to the outer wall of the first card plate.

[0012] As a further description of the above technical solution: The first claw has a slidable limit pin inside, and the outer wall of the limit pin is slidably connected to the inside of the second card plate.

[0013] This utility model has the following beneficial effects: 1. In this utility model, by pulling the rotating plate to make it rotate on the inner wall of the support plate, the rotation of the rotating plate drives the internal rotating column to rotate. Then, during the process of the rotating column being subjected to force, it drives the sliding rod to move. Then, the sliding rod drives the retaining ring to move, so that its inner wall slides on the outer wall of the retaining block, thereby achieving the effect of quickly configuring the counterweight block. This solves the problem that the lack of a quick configuration mechanism means that adjusting the center of gravity or buoyancy characteristics of the buoy will become difficult in the deep sea environment, and improves the convenience of the counterweight structure of the deep-sea buoy.

[0014] 2. In this utility model, the limiting pin is first pulled out, and then the second mast is rotated to drive the bottom sealing disc, the first clamping plate and the second clamping claw to rotate. Then the inner wall of the second clamping claw will separate from the outer wall of the first clamping plate, and the inner wall of the first clamping claw will separate from the side wall of the second clamping plate. After the sealing disc rotates out, the inner wall of the second hollow column can be exposed, which achieves the effect of convenient concrete pouring. It solves the problem that the transportation and installation of heavy concrete blocks are usually troublesome, requiring large mechanical equipment for handling and positioning, which increases the demand for logistics and manpower, and improves the deployment efficiency of the counterweight structure of deep-sea buoys.

[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] Reference Figures 1-4 This utility model provides an embodiment of a deep-sea buoy counterweight structure, including a first hollow column 4. The first hollow column 4 is used to provide a core vertical support frame for the buoy and also serves as the main body of the concrete-filled cavity, providing basic buoyancy and adjustable counterweight space for the buoy, ensuring the structural stability of the buoy in the deep-sea environment. A first mast 2 is fixedly connected to the bottom of the first hollow column 4, and a battery 1 is fixedly connected to the bottom of the first mast 2. The battery 1 is used to provide power support for electrical components such as the second antenna 9 and the first antenna 8 on the buoy, ensuring the continuous operation of the buoy's communication function and providing an energy foundation for signal transmission in the deep-sea environment. This is existing technology and will not be described in detail here. A counterweight block 3 is slidably connected to the outer wall of the first mast 2. The counterweight block 3 is used to change the overall center of gravity distribution of the buoy by adjusting its position on the first mast 2 or by increasing or decreasing its number, thereby adapting to the buoyancy balance requirements under different deep-sea conditions and preventing the buoy from tilting or overturning due to the shift in the center of gravity. The outer wall of the counterweight block 3 is provided with a buckle assembly. The snap-fit ​​assembly includes a support plate 16, which provides a fixed support base for the rotating shaft 18, ensuring that the rotating shaft 18 remains stable under force and preventing transmission deviation due to unstable support, thus ensuring the accuracy of the snap-fit ​​action. The side wall of the support plate 16 is fixedly connected to the outer wall of the counterweight 3, and the inner wall of the support plate 16 is rotatably connected to the rotating shaft 18. The rotating shaft 18 rotates in conjunction with the rotating plate 17, providing the rotating axis for the rotating plate 17, allowing the rotating plate 17 to rotate around a fixed axis, thereby converting the operator's external force into the power to drive the sliding rod 20 to move, achieving the effect of power transmission. The outer wall of the rotating shaft 18 is rotatably connected to the rotating plate 17, and the inside of the rotating plate 17 is rotatably connected to a rotating column 19. The inside of the rotating column 19 is slidably connected to a sliding rod 20, and one end of the sliding rod 20 is fixedly connected to a retaining ring 21. The inside of the retaining ring 21 is slidably connected to a retaining block 22, and the side wall of the retaining block 22 is fixedly connected to... A second hollow column 5 is fixedly connected to the top of the first hollow column 4, attached to the outer wall of the counterweight block 3. A sealing disc 10 is slidably connected to the top of the second hollow column 5. The sealing disc 10 is used to seal the top of the second hollow column 5 to prevent seawater from entering the internal cavity of the first hollow column 4 and the second hollow column 5, thus avoiding performance failure of the filled concrete due to seawater immersion. At the same time, it provides a fixed support foundation for the second mast 7. Horizontal floats 6 are fixedly connected to the outer walls of both the first hollow column 4 and the second hollow column 5. The horizontal floats 6 are used to provide additional buoyancy for the buoy. By fixing the horizontal distribution structure on the outer walls of the first hollow column 4 and the second hollow column 5, the contact area between the buoy and the seawater is increased, improving the buoy's anti-tilting ability in deep-sea waves and ensuring the overall buoyancy balance of the buoy. The second mast 7 is fixedly connected to the top of the sealing disc 10. The second antenna 9 is fixedly connected to the top of the second mast 7. Multiple first antennas 8 are fixedly connected to the outer wall of the second mast 7.

[0019] Reference Figure 1 and Figure 5 A second claw 13 is fixedly connected to the outer wall of the sealing disc 10. The second claw 13 engages and disengages with the first clamping plate 11. When the two engage, the vertical displacement of the sealing disc 10 is restricted. When the two disengage, the sealing disc 10 is allowed to be removed from the top of the second hollow column 5, thus achieving the effect of initially fixing and releasing the sealing disc 10. A second clamping plate 15 is fixedly connected to the outer wall of the sealing disc 10. A first clamping plate 11 is fixedly connected to the outer wall of the second hollow column 5. A first claw 12 is fixedly connected to the outer wall of the second hollow column 5. The inner wall of the first claw 12 is rotatably connected to the outer wall of the second clamping plate 15. The inner wall of the second claw 13 is rotatably connected to the outer wall of the first clamping plate 11. A limit pin 14 is slidably connected inside the first claw 12. The outer wall of the limit pin 14 is slidably connected inside the second clamping plate 15.

[0020] Working principle: When it is necessary to adjust the buoy's center of gravity and buoyancy balance, the operator drives the rotating plate 17 in the latching assembly to rotate around the rotating shaft 18 on the inner wall of the support plate 16. Since the rotating column 19 is rotatably connected to the rotating plate 17, the rotation of the rotating plate 17 will synchronously cause the rotating column 19 to shift at an angle. The inner wall of the rotating column 19 is in sliding engagement with the sliding rod 20. The lateral thrust generated by the angle shift will drive the sliding rod 20 to move horizontally. The retaining ring 21 fixed at one end of the sliding rod 20 moves synchronously, and its inner wall will slide along the retaining block 22 fixed on the outer wall of the counterweight 3. When the retaining ring 21 and the retaining block 22 are disengaged, the counterweight 3 can slide freely along the outer wall of the first mast 2 to achieve vertical position adjustment or rapid addition or subtraction. After the counterweight 3 moves to the target position, the rotating plate 17 is pushed in the opposite direction. Through the above transmission path, the retaining ring 21 is tightly engaged with the retaining block 22 again, thus completing the fixation of the counterweight 3. When it is necessary to increase the overall weight of the buoy by filling it with concrete to adapt to specific sea conditions, firstly, pull out the limiting pin 14 inside the first claw 12 to release its locking constraint on the second clamping plate 15. Then, rotate the second mast 7, and the sealing plate 10 fixed at its bottom will rotate synchronously, causing the second claw 13 and the second clamping plate 15 on the outer wall of the sealing plate 10 to disengage from the first clamping plate 11 and the first claw 12 on the outer wall of the second hollow column 5, respectively. Specifically, the inner wall of the second claw 13 separates from the outer wall of the first clamping plate 11, and the inner wall of the first claw 12 separates from the side wall of the second clamping plate 15. At this time, the sealing plate 10 can be removed from the top of the second hollow column 5, exposing the internal cavity of the second hollow column 5, and the operator can directly pour concrete into the second hollow column 5 and the first hollow column 4 connected below. After the concrete has solidified to the preset counterweight, the sealing disc 10 is reset to the top of the second hollow column 5. The second mast 7 is rotated in the opposite direction to make the second claw 13 re-engage with the first plate 11, and the first claw 12 with the second plate 15. Finally, the limiting pin 14 is inserted through the first claw 12 and the second plate 15 to complete the fixing and sealing of the sealing disc 10.
