The reel-in device includes a spring and a gear transmission structure, which comprises a large gear, a small gear, and a timing belt. This utility model, through the spring and gear transmission structure (the large and small gears meshing, and the timing belt driving) in the reel-in device, enables automatic reel-in and reel-out of nylon rope.

Description

Technical Field

[0001] This utility model belongs to the field of diving monitoring, and in particular relates to a novel diving beacon rope reel. Background Technology

[0002] In diving, buoys and beacon lines are crucial equipment for ensuring diver safety and marking dive locations. Their core function is to provide underwater divers with a directional reference through the buoy's reflection on the water's surface, and to assist in determining dive depth. Currently, divers need to obtain depth data at the dive site using a depth gauge before entering the water, and then manually select a buoy line of suitable length to connect to the buoy. This process has significant limitations and can no longer meet the demands of modern diving for safety, convenience, and teamwork.

[0003] The shortcomings of existing technologies are mainly reflected in the following aspects.

[0004] 1. The buoy line length cannot be adaptively adjusted: When the dive site shifts during the dive (e.g., water currents cause the diver to deviate from the initial dive point) or the water depth changes dynamically (e.g., due to tidal influences), a fixed-length buoy line is prone to problems such as becoming too long and tangled or too short and taut. If it is too long, the line may become entangled in diving equipment or underwater obstacles, affecting the safety of the dive; if it is too short, the buoy will not be able to maintain stable visibility on the surface, thus losing its beacon function.

[0005] 2. Multiple buoy lines of different specifications need to be carried: Due to the large differences in water depth at different dive sites (such as shore diving, boat diving, and cave diving, the water depth can range from several meters to tens of meters), divers need to carry multiple buoy lines of different lengths in advance based on experience or test data. This not only increases the burden of carrying equipment and occupies the storage space of the diving bag, but may also lead to equipment waste or unusability due to incorrect line selection.

[0006] 3. Lack of depth indication function: The existing buoy rope is only used as a connecting medium and does not integrate depth markings or scales. Divers cannot intuitively judge the current diving depth through the rope and need to rely on additional equipment such as dive computers. If the equipment malfunctions, it may cause safety risks such as decompression sickness due to incorrect depth judgment.

[0007] 4. Lack of multi-diver linkage capability: In group diving scenarios, existing buoy lines can only connect a single diver to the buoy, and cannot link multiple divers together. When team members are scattered, it is difficult to form a coordinated beacon system, increasing the risk of losing contact, especially in underwater environments with low visibility, where the safety hazards are even more prominent.

[0008] Therefore, in view of the shortcomings of existing diving beacon lines in terms of length adjustment, equipment portability, depth sensing and team coordination, there is an urgent need to design a new type of diving beacon line retractor with automatic release and take-up, depth marking and serial connection functions, so as to optimize the diving operation process and improve diving safety and convenience.

[0022] 3. This utility model uses a nylon rope with red and yellow sections spaced 1 meter apart.

[0031] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0033] One objective of this invention is to provide a novel underwater beacon line reel. This invention utilizes a spring-loaded mechanism and a gear transmission structure (meshing of a large and small gear, driven by a synchronous belt) in the reel device to automatically reel in and out the nylon rope. Through the coordination of the reel-in / out control rod and the gear transmission system, a combination of manual fine-tuning and automatic reel-in / out can be achieved. Divers no longer need to manually wind the rope, saving underwater operation time and improving the diving experience and efficiency. When the diver moves or the water depth changes, the rope length can be adjusted in real time according to the diver's movements, avoiding the tangling and tension problems of traditional fixed-length buoy lines, reducing the risk of entanglement with underwater obstacles, ensuring stable visibility of the buoy on the surface, and guaranteeing the continuity of the diver's bearing reference.

[0034] See Figure 1-3 This embodiment provides a novel diving beacon line retractor, which includes a housing 1 and a retracting control rod 3, and also includes a retracting device disposed in the housing 1. The retracting device includes a spring 17 and a gear transmission structure, which includes a large gear 15, a small gear 12 and a timing belt 9.

[0035] In this setup, the automatic winding and unwinding of the nylon rope 4 can be achieved by utilizing the spring 17 and the gear transmission structure (meshing of the large gear and the small gear, and synchronous belt drive). By cooperating with the winding and unwinding control rod and the gear transmission system, manual fine-tuning and automatic winding and unwinding can be combined. Divers do not need to manually wind the rope, saving underwater operation time and improving the diving experience and efficiency.

[0036] See Figure 1-3 The timing belt 9 connects the gear shaft 6 and the pinion shaft 13. The pinion 12 meshes with the large gear 15. The pinion 12 is connected to the pinion shaft 13 via a C4x20 key 18. The large gear 15 is connected to the spring shaft 14 via a C4x10 key 19.

[0037] Furthermore, a spool 5 is provided on the gear shaft 6, and a nylon rope 4 is wound on the spool 5.

[0038] Specifically, the nylon rope 4 features a red and yellow alternating design, with one meter of red and one meter of yellow, and its length is set to 20m. When diving, the current water depth can be estimated based on the color. The "one-meter red and yellow alternating design" of the nylon rope 4 can reduce reliance on equipment such as dive computers, reduce the risk of depth judgment errors caused by equipment failure, and help prevent safety issues such as decompression sickness.

[0039] In this setup, the large gear 15 and the small gear 12 work together to achieve a 1:4 reduction ratio, achieving primary reduction. Then, the small gear 12 and the gear shaft 6 are connected via a synchronous belt 9 to achieve a 1:2 reduction ratio, achieving secondary reduction, thus enabling the automatic reeling of the nylon rope 4. The nylon rope 4 is wound around the reel 5, which is coaxial with the gear shaft 6. The spring 17 is coaxial with the large gear 15. When the spring 17 drives the large gear 15 to rotate one revolution, the reel 5 rotates 10 revolutions, thereby reeling in or releasing the nylon rope 4 to the required length. When the desired length is reached, rotating and pressing the reel control bar 3 stops the automatic reel reel. When the diver moves or the water depth changes, the length of the nylon rope 4 can also be adjusted in real time with the diver's movements, avoiding the tangling and tension problems of traditional fixed-length buoy lines, reducing the risk of entanglement with underwater obstacles, ensuring stable visibility of the buoy on the surface, and guaranteeing the continuity of the diver's positional reference.

[0040] See Figure 1-3The spring 17 is mounted on the spring shaft 14, and the spring 17 and the large gear 15 are coaxial. The spring 17 is made of high carbon spring steel.

[0041] In this setup, the spring 17 is made of high-carbon spring steel. When the spring 17 is used, it drives the large gear 15 to rotate one revolution, and the spool 5 to rotate 10 revolutions, thereby causing the nylon rope 4 to be wound up or released to the corresponding length.

[0042] See Figure 1-3 Each of the gear shaft 6, pinion shaft 13, and spring shaft 14 is provided with a deep groove ball bearing 8 at the gear shaft, a deep groove ball bearing 10 at the pinion shaft, and a deep groove ball bearing 20 at the spring shaft. At the connection between the deep groove ball bearing 8 at the gear shaft, the deep groove ball bearing 10 at the pinion shaft, and the deep groove ball bearing 20 at the spring shaft and the front end of the gear shaft 6, the pinion shaft 13, and the spring shaft 14, a Ф16 shaft retaining ring 7, a Ф24 shaft retaining ring 11, and a Ф30 shaft retaining ring 21 are fixed.

[0043] Furthermore, a Ф10 shaft retaining ring 2 is provided at the rear end of the pinion shaft 12.

[0044] Furthermore, a Ф15 shaft retaining ring 16 is provided at the front end of the large gear 15.

[0045] In this setup, deep groove ball bearings, shaft retaining rings, flat keys, and other components secure the gear shafts and transmission structures, ensuring smooth transmission under underwater pressure and water flow impact. The mainspring 17 provides stable line retrieval power. The overall structure possesses excellent corrosion resistance and reliability, extending the service life of the mainspring 17 and providing it with stable line retrieval power. Furthermore, it enables the connection between a single diver and the buoy, thereby facilitating the tandem connection of ropes among multiple divers.

[0046] This embodiment provides a novel underwater beacon line reel, the working principle of which is as follows:

[0047] In operation, a spring-loaded spring 17, along with a large gear 15 and a small gear 12, achieves a 1:4 reduction ratio for primary speed reduction. Subsequently, the small gear 12 and the gear shaft 6 are connected via a synchronous belt 9 to achieve a 1:2 reduction ratio for secondary speed reduction, thus enabling automatic reel-in of the nylon rope 4. When the spring-loaded spring 17 drives the large gear 15 to rotate one revolution, the reel 5 rotates ten revolutions, causing the nylon rope 4 to retract or release to the desired length. When the desired length is reached, rotating and pressing the reel-in / release control bar 3 stops the automatic retraction. The length of the nylon rope 4 also adjusts in real-time to the diver's movements as they move or the water depth changes.

[0048] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0049] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
