Description

Technical Field

[0001] This utility model relates to the field of water rescue and water operation equipment, specifically to a buoyancy bag chain structure. Background Technology

[0002] Buoyancy devices are essential equipment for water operations and rescue, and are widely used in scenarios such as lifesaving, marking, securing, and towing. Most existing buoyancy devices are in the form of closed bags or rigid floats, and they mainly rely on internal air or foam materials to generate buoyancy to ensure stable floating on the water surface.

[0003] Existing buoyancy bags are prone to drifting with currents or waves, making it difficult to maintain a fixed position in the target area and hindering rescue efforts. Therefore, it is necessary to attach ropes to the buoyancy bags for fixation. However, due to their relatively light weight, the buoyancy bags have a high center of gravity when floating on the water, making them prone to tipping over and affecting safety. Consequently, counterweights are needed to balance the buoyancy bags. Furthermore, during prolonged towing, the traction points where the buoyancy bag connects to the rope repeatedly come into contact with the rope and chain, easily causing wear and tear or even scratches on the surface of the buoyancy bag, thus affecting its lifespan.

[0004] Therefore, there is an urgent need to design a buoyancy bag chain structure to meet the current needs of water rescue. Utility Model Content

[0005] The purpose of this invention is to provide a buoyancy bag chain structure that can lower the center of gravity of the buoyancy bag through chain counterweight, thereby improving its positioning stability (anti-overturning ability) under the action of water flow and waves, and effectively preventing it from drifting with the current; at the same time, with wear-resistant thickened pads and standardized rope interfaces, the durability of the device is improved, meeting the usage requirements of scenarios such as water rescue and river construction.

[0006] The technical solution adopted by this utility model to solve the above problems is: a buoyancy bag chain structure, including a bag body, two sets of counterweight connecting components are symmetrically arranged on one side of the bag body, the two ends of the counterweight connecting components are detachably connected to the bag body through fixing rings, the counterweight connecting components include straps and chains, and the straps and chains are connected by rope connectors.

[0007] Preferably, the rope connector is located at the end of the chain and uses a standard rope interface.

[0008] Preferably, the bag body is provided with two sets of long strip-shaped wear-resistant thickened pads, which are located on the contact side between the bag body and the counterweight connecting component.

[0009] Preferably, the bag body is provided with a fixing seat that is adapted to connect with the fixing ring, and a connecting ring is rotatably provided on the fixing seat.

[0010] Preferably, the fixing ring includes a first half-ring, a second half-ring, and two sets of bolts. The first half-ring has threaded holes at both ends that are adapted to the threaded connection of the bolts, and the second half-ring has stepped holes that are adapted to the bolt heads.

[0011] Preferably, the end faces of the first half-ring are provided with annular protrusions, and the end faces of the second half-ring are provided with grooves that are adapted to the annular protrusions.

[0012] Compared with the prior art, this utility model has the following advantages and effects:

[0013] This invention effectively lowers the center of gravity of the buoyancy bag by incorporating detachable counterweight connecting components on both sides and using a chain structure within these components. This improves the bag's stability and anti-capsulation capabilities in flowing water and wave conditions. The addition of a standard rope connector at the chain end enhances the bag's ability to be quickly attached to external ropes, anchor points, or rescue equipment, increasing its flexibility and adaptability. Long, wear-resistant, thickened pads at the contact points between the counterweight connecting components and the bag effectively reduce surface wear caused by dragging and friction, improving the overall durability and lifespan. Balance straps at both ends of the bag, connected to straps, effectively prevent the chain from flipping to the back of the bag in undulating water conditions, ensuring the counterweight structure remains underwater and maintaining overall force balance.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0020] Example:

[0021] See Figures 1-4 In this embodiment, a buoyancy bag chain structure is involved, which is specifically used for floating markers, location positioning and anchoring in water rescue and river construction. Specifically, it includes a bag body 11, on one side of which two sets of counterweight connecting components 12 are symmetrically arranged. The two ends of the counterweight connecting components 12 are detachably connected to the bag body 11 through fixing rings 13. The counterweight connecting components 12 include straps 14 and chains 15, and the straps 14 and chains 15 are connected by rope connectors 16.

[0022] Specifically, in this embodiment, the chain 15 is made of interconnected galvanized steel links. Workers carry the assembled buoyancy bag chain structure to the river construction site or rescue location, and then place the bag 11 on the water surface. The bag 11 floats stably using its own buoyancy. The weight of the chain 15 lowers the overall center of gravity of the buoyancy bag during floating, making it more stable in the water and less prone to being overturned by currents or waves. This is suitable for scenarios requiring a fixed location (such as rescue anchor points). If it needs to be fixed to the shore or anchor point, the rope connector 16 is used to quickly attach the rope to an anchor on the shore (such as a mooring post, railing, etc.), reducing the possibility of the buoyancy bag drifting with the current and facilitating the maintenance of the target area during rescue or operations.

[0023] In this embodiment, the rope connector 16 is located at the end of the chain 15 and uses a standard rope interface (such as a D-ring or shackle). The chain 15 provides a sturdy attachment point, facilitating the binding of ropes, rescue equipment, or other heavy objects, thus enhancing functionality (such as towing or anchoring).

[0024] The bag body 11 is provided with two sets of elongated, wear-resistant thickened pads 17, which are made of high-strength, wear-resistant nylon composite material. The thickened pads 17 are positioned on the contact side between the bag body 11 and the counterweight connecting component 12, and their length and width should cover all sliding paths of the straps 14 and chains 15 (mainly rope connectors 16) on the surface of the bag body 11. During use, when the counterweight connecting component 12 is dragged, its metal chain links and rope connectors 16 directly contact the thickened pads 17. The thickened pads 17 effectively distribute pressure and isolate direct friction with the bag body 11, effectively preventing wear or tear on the surface of the bag body 11, thereby improving the service life of the buoyancy bag.

[0025] The bag body 11 is provided with balance straps 18 at both ends. The main body of the balance strap 18 is fixedly set on the surface of the bag body 11, and its end is provided with a collar 19, which is sleeved on the binding strap 14. In this embodiment, the balance strap 18 is made of polyester webbing, and the binding strap 14 is restricted to one side of the outer surface of the bag body 11 by the collar 19. In this way, even if a set of counterweight connecting parts 12 shakes violently in the water under the action of current, it will not flip to the back of the bag body 11, ensuring that all chains 15 used for counterweights are located in the predetermined underwater area, avoiding the phenomenon of the bag body 11 tipping over due to the center of gravity shifting because one side is unbalanced, thereby further improving the attitude stability and reliability of the buoyancy bag.

[0026] The bag body 11 is provided with a fixing seat 21 that is adapted to connect with the fixing ring 13. A connecting ring 22 is rotatably mounted on the fixing seat 21, and the fixing ring 13 is connected to the connecting ring 22. In this embodiment, the fixing ring 13 adopts a detachable connection structure to facilitate the disassembly of the counterweight connecting component 12. The connecting ring 22 is a triangular ring. Specifically, the fixing ring 13 includes a first half-ring 23, a second half-ring 24, and two sets of bolts 25. In this embodiment, both the first half-ring 23 and the second half-ring 24 are CNC machined from aluminum alloy to ensure dimensional accuracy and surface finish. The first half-ring 23 has M6 internal thread holes 26 at both ends that mate with the external threads of the bolts 25. A stepped hole 27 is opened at the corresponding position of the second half ring 24. The upper diameter of the stepped hole 27 is slightly larger than the head diameter of the bolt 25, and the lower section matches the stud specification of the bolt 25. When assembling the bolt 25, first insert the bolt 25 through the stepped hole 27 of the second half ring 24, and then screw the threaded end of the bolt 25 into the threaded hole 26 of the first half ring 23 to complete the fit between the first half ring 23 and the second half ring 24.

[0027] The first half-ring 23 has annular bosses on both ends, and the second half-ring 24 has grooves 29 on its end face (the lower end of the stepped hole 27) that fit the annular bosses. This allows the annular bosses at both ends of the first half-ring 23 to engage with the grooves 29 of the second half-ring 24 when the two halves (first half-ring 23 and second half-ring 24) are closed. This initial positioning between the first half-ring 23 and second half-ring 24 facilitates the screwing in of the bolt 25. Furthermore, under prolonged tension (uneven load or instantaneous load), the fixed ring 13 is prone to wear on the threaded connection structure (threaded hole 26 or bolt 25 external thread), leading to loosening of the connection between the first half-ring 23 and the second half-ring 24. The resulting shaking can further accelerate the wear of the threaded connection structure. This embodiment, through the design of the annular bosses and grooves 29, alleviates loosening even under wear on the threaded connection structure, preventing accelerated wear and improving the service life of the fixed seat 21 and the connection reliability of the counterweight connecting component 12.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
