Description

Technical Field

[0001] This utility model relates to the field of diving equipment technology, and in particular to a diving propulsion device. Background Technology

[0002] With the increasing popularity of ocean exploration, underwater operations, and diving, the performance requirements for diving propulsion devices, as core equipment that helps divers improve underwater mobility and reduce physical exertion, are constantly increasing. Existing diving propulsion devices mostly adopt a single thruster or a simple parallel dual-thruster structure. While these can basically meet basic mobility needs, they still have significant shortcomings in terms of operational flexibility, grip stability, and functional adaptability, making them difficult to adapt to complex underwater environments.

[0003] On the one hand, the existing underwater propulsion device has an unreasonable design of its guidance and adjustment structure, which relies on the speed difference of the thruster itself to achieve directional control. During the descent, the device is prone to "nose-up" and it is difficult to accurately control the descent angle. On the other hand, when deceleration is required, there is a lack of a dedicated resistance adjustment mechanism. The device can only be decelerated by turning off the thruster and relying on the natural resistance of the water. The gliding distance caused by inertia is too long, which not only affects the accuracy of operation, but may also increase the risk of underwater collisions. In some cases, the impact force generated by sudden deceleration may even cause the device to slip out of hand.

[0004] On the other hand, the grip structure of existing devices lacks sufficient consideration for ergonomics, and most only have simple hand grips. When divers hold the device for a long time, they need to exert continuous force with their arms to maintain its stability, which can easily lead to fatigue. At the same time, there is no effective limiting and matching structure between the arm and the device. When the device is impacted by underwater currents or when force is applied during operation, it is easy for the device to shake or shift, which further reduces the stability of operation. The shaking problem is more prominent when carrying auxiliary equipment such as photography and lighting, which affects the operation results.

[0005] In addition, some underwater propulsion devices lack functional expandability and standardized expansion installation structures, making it difficult to add auxiliary components such as underwater photography equipment and lighting fixtures according to actual needs, thus limiting their applicability in underwater exploration, photography and other scenarios; and the control module design of some dual-thrust devices is unreasonable, with poor synchronization between the two thrusters, which easily leads to uneven power output, causing the device to deviate and increasing the difficulty of operation.

[0006] Therefore, there is an urgent need for a diving propulsion device with flexible guidance and adjustment functions, a stable grip structure and good expandability, in order to solve the problems of difficulty in diving control, poor deceleration effect, grip fatigue, insufficient stability and limited functions in the existing technology, and meet the diverse needs of divers in complex underwater environments.

[0008] This utility model also provides a diving propulsion device as described above, comprising: a first propeller and a second propeller, wherein a support plate is fixedly connected to the outer surface of the first propeller, and the other end of the support plate is fixedly connected to the outer surface of the second propeller; both the first propeller and the second propeller are provided with hand-held devices on their outer surfaces, each hand-held device including a fixed base, a handle fixedly connected to the side surfaces of both fixed bases, a start switch provided on the outer surface of both handles, a slide rail fixedly connected to the upper surface of both fixed bases, a slide seat slidably connected inside the two slide rails, a rotating seat rotatably connected to the inner side of the upper end of both slide seats, and a guide plate fixedly connected to the outer surface of the rotating seat;

[0009] Both fixed seats are fixedly connected to a shaft seat on their upper surface. Both shaft seats are rotatably connected to a movable connecting rod via a rotating shaft. The other ends of the two movable connecting rods are respectively connected to both sides of the guide plate via a rotating shaft. Both slides are fixedly connected to a handle on their outer surface. Both slides are connected to a reaction spring via a spring seat on their outer surface.

[0017] Beneficial effects

[0018] Compared with existing technologies, this diving propulsion device allows for adjustable tilt angle of the guide plate by using a hand-operated handle. This makes it easier for the device to descend in water and increases resistance by changing the guide plate to a 90-degree vertical position during deceleration. Through the action of the forearm bracket and the parallel plate, a more stable and relatively effortless grip is achieved at the upper and lower ends of the forearm during use. This effectively solves the problems of difficulty in controlling the nose tilt during descent and loss of grip due to inertia during deceleration. Attached Figure Description

[0030] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0031] Reference Figure 1-8 This utility model discloses a diving propulsion device, comprising: a first thruster 1 and a second thruster 2. A support plate 8 is fixedly connected to the outer surface of the first thruster 1 for supporting the arm. The other end of the support plate 8 is fixedly connected to the outer surface of the second thruster 2. Both the first thruster 1 and the second thruster 2 are provided with handheld devices, each handheld device including a fixed base 17. Hand grips 18 are fixedly connected to the side surfaces of both fixed bases 17 for hand gripping. Both hand grips 18 are provided with start switches 19 on their outer surfaces for controlling the start and stop of the two thrusters. Slide tracks 20 are fixedly connected to the upper surfaces of both fixed bases 17. Slide seats 21 are slidably connected inside the two slide tracks 20. Rotary seats 22 are rotatably connected to the inner upper ends of both slide seats 21. A guide plate 13 is fixedly connected to the outer surface of the rotating seat 22. By adjusting the upward angle of its tail end, it achieves the function of assisting diving. The maximum upward angle of the tail end of the guide plate 13 is 90 degrees. When in this state, it effectively increases resistance, achieving the purpose of deceleration.

[0032] Both fixed seats 17 have shaft seats 23 fixedly connected to their upper surfaces. Both shaft seats 23 are rotatably connected to movable connecting rods 27 via rotating shafts. The other ends of the two movable connecting rods 27 are respectively connected to the two sides of the guide plate 13 via rotating shafts. Both slide seats 21 have handles 26 fixedly connected to their outer surfaces. Both slide seats 21 have reaction springs 24 connected to their outer surfaces via spring seats. Both fixed seats 17 have limit rods 25 fixedly connected to their upper surfaces to limit the range of motion of the movable connecting rods 27. Their function is that when the movable connecting rods 27 come into contact with them, the force of the reaction springs 24 keeps the guide plate 13 in a horizontal state. At this time, the resistance of the propeller to the water is minimal when the propeller moves forward, and it maintains a straight-line motion. The other end of the reaction spring 24 abuts against the limit rod 25; both the first thruster 1 and the second thruster 2 are equipped with brushless motors 15 inside, and the output ends of the brushless motors 15 are fixedly connected to impellers 16. The upper surfaces of the first thruster 1 and the second thruster 2 are fixedly connected to parallel seats 3, and a parallel plate 11 is fixedly connected between the two parallel seats 3 for connecting the two thrusters. At the same time, it also plays the role of pressing down the upper end of the arm during use, which just matches the forearm support 10 to maintain the stability of the device when it is held in the water.

[0033] Both the first thruster 1 and the second thruster 2 have a conical guide head 14 fixedly connected to their front ends. Both the first thruster 1 and the second thruster 2 have a control module inside, which includes an energy storage unit and a main board. The two control modules are connected in parallel and control synchronously. Both the first thruster 1 and the second thruster 2 have a water inlet grille 6 on their outer surfaces. Both the first thruster 1 and the second thruster 2 have a drain outlet 7 at their rear ends, and the impeller 16 is located inside the drain outlet 7.

[0034] A display 4 is mounted on the outer surface of the left parallel base 3, and a charging port 5 is located on the side of the parallel base 3. The display 4 and the charging port 5 are electrically connected to the control module. Forearm brackets 10 are fixedly connected to both sides of the upper surface of the support plate 8 for securing the forearm. A safety lanyard hook 9 is fixedly connected to the outer surface of the support plate 8 for attaching a safety lanyard to prevent the device from slipping out of the hand in water. An expansion hole 12 is provided on the upper surface of the parallel plate 11 for mounting cameras and lighting equipment. Both the top and bottom surfaces of the front end of the parallel plate 11 are chamfered. The top of the limit rod 25 abuts against the movable connecting rod 27, and the start switch 19 is electrically connected to the control module.

[0035] Working principle: Before use, fully charge the power storage unit of the control module through the charging port 5, connect one end of the safety rope to the safety rope hook 9, and fix the other end to the diver to improve safety. If auxiliary equipment such as photography and lighting needs to be installed, it can be fixed through the expansion hole 12 of the parallel plate 11.

[0036] Upon startup, the diver places their forearm on the forearm bracket 10 of the support plate 8, grips the handle 18, and has their upper arm in contact with the parallel plate 11, forming a stable grip with upper and lower limits, effectively reducing shaking during operation. Pressing the start switch 19 on the handle 18 simultaneously activates the brushless motors 15 inside the first thruster 1 and the second thruster 2. The brushless motors 15 drive the impeller 16 to rotate at high speed. Water flows through the inlet grille 6 into the thruster and is discharged at high speed through the outlet 7, generating a reverse thrust that propels the device and the diver forward underwater. The conical guide heads 14 at the front of the first thruster 1 and the second thruster 2 reduce water resistance during movement, ensuring stability during straight-line travel.

[0037] During the descent adjustment, the diver holds the handle 26 and pushes the slide 21 inward. The slide 21 slides along the slide rail 20 and compresses the reaction spring 24. At the same time, the guide plate 13 rotates around the shaft seat 23 through the rotating seat 22. The movable connecting rod 27 tilts upward synchronously with the tail end of the guide plate 13. By adjusting the tilting angle of the guide plate 13, a downward guiding force is provided to the device, making the descent action easy and avoiding the "nose-up" phenomenon. The limiting rod 25 can limit the swing range of the movable connecting rod 27 and prevent the guide plate 13 from rotating excessively.

[0038] When deceleration is required, continuously push the handle 26 to tilt the guide plate 13 upward to a 90-degree vertical position. At this time, the guide plate 13 forms the maximum contact area with the water flow, significantly increasing water resistance, quickly reducing the travel speed, and avoiding the risk of collision caused by excessive inertial gliding. After deceleration is completed, release the handle 26, the reaction spring 24 returns to its deformation, pushes the slide 21 to reset, and the guide plate 13 returns to the horizontal position under the traction of the movable linkage 27, restoring the minimum resistance travel mode.

[0039] During diving, the display 4 on the left parallel mount 3 displays the operating parameters of the two thrusters (such as speed and power output) and the remaining power of the battery storage unit in real time, so that the diver can keep track of the equipment status in real time and ensure the safety of the operation; the control module of the two thrusters adopts a parallel synchronous control design to ensure uniform power output and avoid deviation of the driving direction.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
