Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a battery replacement device for a universal light buoy. Background Technology

[0002] As an important navigational aid in ports, light buoys play an irreplaceable role in ship navigation and port entry / exit. Northern Chinese ports, affected by sea ice in winter, require annual spring and winter buoy replacement operations to replace ice buoys and ensure stable performance of navigation aids during winter, thus guaranteeing safe navigation. With continuous advancements in science and technology, all-season light buoys have been gradually adopted and promoted, effectively solving the problem of frequent spring and winter buoy replacements in northern ports. However, due to the influence of sea ice in winter, all-season light buoys use batteries for power supply instead of easily damaged and icy solar panels. The batteries, due to their weight, can affect the stability of the all-season light buoy; therefore, the batteries are placed in the lower part of the buoy body at a depth of 5-6 meters. Whenever the battery of an all-season light buoy runs out of power and needs replacement, operators must work from a boat along the side of the buoy, securing it to the work vessel, and using battery cables to lift the heavy battery (weighing hundreds of kilograms) from the buoy body at a depth of 5-6 meters for replacement.

[0003] The process of lifting and replacing the battery requires workers to work along the side of the ship and exert continuous force, which is extremely physically demanding and drastically increases the risk of the operation. At the same time, the operation is time-consuming and inefficient, increasing the risk of the working vessel approaching the light buoy. Utility Model Content

[0004] In order to solve the technical problem of difficult battery replacement for all-season universal light buoys in the prior art, this utility model provides a battery replacement device for all-season universal light buoys.

[0005] Therefore, the present invention provides the following technical solution: A battery replacement device for a year-round universal light buoy includes a fixing ring and a load-bearing crossbar. The fixing ring is coaxially installed with the buoy barrel at the top opening of the buoy body. The diameter of the fixing ring is equal to the diameter of the top opening of the buoy body. The load-bearing crossbar is installed on the fixing ring, and a roller is mounted on the load-bearing crossbar at the center of the fixing ring via a bearing.

[0006] Furthermore, one end of the load-bearing crossbar is movably connected to the fixed ring via a support, and a support rod is fixedly installed on the fixed ring. The upper end of the support rod is provided with a support groove, which can engage with the free end of the load-bearing crossbar.

[0007] Furthermore, bolt holes are evenly distributed along the circumferential direction on the fixing ring.

[0008] Furthermore, the inner wall of the support groove is provided with an anti-slip pad layer.

[0009] Furthermore, the roller surface has an annular groove along the circumferential direction.

[0010] Furthermore, the support is a hinged support or a universal joint support.

[0011] Advantages and positive effects of this utility model: The fixing ring is coaxially mounted with the buoy body and its diameter is not less than the diameter of the opening at the top of the buoy body. This ensures that the fixing ring accurately covers the opening and is aligned with the center of the buoy barrel. Simultaneously, the roller on the load-bearing crossbar is precisely located at the center of the fixing ring, meaning the roller is completely coincident with the center of the buoy barrel. This structure allows the battery to move vertically during lifting and lowering, avoiding battery misalignment caused by the lack of a positioning structure in existing technologies. It eliminates the need for repeated adjustments to the battery position, allowing the battery to smoothly enter and exit along the central axis of the buoy barrel. The fixing ring, through its rigid connection to the opening at the top of the buoy body, allows the load-bearing crossbar to be mounted on the fixing ring with the roller at its center, concentrating the force on the central area and preventing tilting caused by unilateral force.

[0012] The load-bearing crossbar serves as a support carrier, and the rollers are mounted at the center of the fixed ring via bearings. During replacement, the battery wires or lifting ropes can rely on the rollers to convert sliding friction into rolling friction, significantly reducing traction resistance. This eliminates the need for large, specialized equipment, significantly reducing the physical labor and equipment dependence costs associated with the replacement operation.

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0017] This utility model provides a battery replacement device for a universal light buoy, such as... Figure 1 As shown, the buoy includes a fixed ring 1 and a load-bearing crossbar 3. The fixed ring 1 has bolt holes 2 evenly spaced along its circumference. The fixed ring 1 is installed at the top opening of the buoy body via the bolt holes 2 and bolts, and is coaxially mounted with the buoy barrel. The diameter of the fixed ring 1 is equal to the diameter of the top opening of the buoy body. One end of the load-bearing crossbar 3 is movably connected to the fixed ring 1 via a support 5, which can be a hinge support or a universal joint support. A roller 6 is rotatably mounted on the load-bearing crossbar 3 at the center of the fixed ring 1 via a bearing. The surface of the roller 6 has an annular groove along its circumference.

[0018] A support rod 8 is fixedly installed on the fixed ring 1. The upper end of the support rod 8 is provided with a support groove 4, which can be engaged with the free end of the weighing crossbar 3. The inner wall of the support groove 4 is provided with an anti-slip pad layer.

[0019] Working principle: First, the fixing ring 1 is rigidly connected to the top opening of the buoy body through the bolt holes 2 evenly distributed along the circumference of the fixing ring 1, and the bolts are used to ensure that the fixing ring 1 and the buoy body are coaxial. This ensures that the center of force of the subsequent load-bearing crossbar 3 coincides with the center of the buoy barrel, avoiding tilting of the device caused by unilateral force. At the same time, the diameter of the fixing ring 1 is not less than the diameter of the top opening of the buoy body, and can completely cover the edge of the opening.

[0020] One end of the load-bearing crossbar 3 is movably connected to the fixed ring 1 through a hinge support or universal joint support 5, so that the load-bearing crossbar 3 can rotate flexibly around the support 5; then the free end of the load-bearing crossbar 3 is inserted into the support groove 4 at the top of the support rod 8 on the fixed ring 1, and the anti-slip pad layer on the inner wall of the support groove 4 is used to increase the friction and prevent the load-bearing crossbar 3 from sliding when there is no external force. At this time, the device is in standby state, the load-bearing crossbar 3 remains horizontal and stable, and the roller 6 at its center is directly above the opening of the buoy body.

[0021] When replacing the battery, first connect the towing rope of the workboat winch or the lifting rope operated manually to the lifting hook of the old battery in the buoy barrel. At the same time, lead the battery wires of the old battery out from inside the buoy barrel and wind them into the annular groove on the surface of roller 6. The annular groove serves two purposes: firstly, it limits the battery wires, preventing them from deviating from the path or rubbing against the inner wall of the buoy barrel during the pulling process; secondly, it allows the wires to move synchronously with the battery as it rises and falls, preventing the wires from getting tangled or knotted.

[0022] The winch of the work vessel is activated or the hoisting rope is pulled manually to provide upward traction. Under this traction, the old battery moves upward along the inner wall of the buoy barrel, simultaneously causing the battery wires wound on the roller 6 to slide upward in sync. Since the roller 6 is rotatably connected to the load-bearing crossbar 3 through a bearing, the sliding friction between the battery wires and the roller is converted into rolling friction of the roller, which greatly reduces the resistance to the movement of the wires. Even in scenarios where the wires are stiff due to low temperatures in winter or prone to sticking in humid conditions in summer, the wires can still move smoothly, avoiding damage from being pulled.

[0023] As the winch continues to pull, the old battery is gradually lifted to the top opening of the buoy body. The weighing bar 3 is then lifted, and the old battery is removed from the fixing ring 1 until the old battery is completely detached from the opening of the buoy body.

[0024] Next, install the new battery into the buoy body using the battery replacement device, loosen the fixing bolt in the bolt hole 2 of the fixing ring 1, and remove the entire device from the opening at the top of the buoy body. After the device is removed, accurately connect the battery wire of the new battery to the lamp terminal of the light buoy, and install the lamp on the top of the buoy body and cover the opening of the buoy body.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
