[0041] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments. However, it should be understood that the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. The positional relationship described in the drawings is only used for illustrative purposes and cannot be understood as a limitation on this patent.

[0042] The utility model provides a powered paddle board, comprising a board body 1, a forward and reverse conversion device 2, a power device 3, a control device 4 and a power supply device 5. It is compatible with other common accessories such as a hand paddle 10 and a foot ring 8. The foot ring 8 is installed at the tail of the board body 1 through an elastic rope 9, and it is tied to the foot to improve safety.

[0043] like Figure 1-5As shown, the hydrodynamic performance of the board 1 is basically the same as that of the traditional paddle board. It can be made into different sizes according to needs, which is convenient for rescue team members to quickly master the operation essentials. It is made of light buoyancy material, and foam or inflatable airbags can be selected to provide sufficient effective buoyancy. Grab rings 7 can be installed at appropriate positions on the front and back sides of the board 1 to facilitate the drowning person to grasp or the rescuer to carry, and other accessories can also be installed as needed; the middle of the board 1 is reserved for the installation space of the power supply device 5; symmetrical water inlets 1.1 are provided on the front and back sides of the middle and rear part of the board 1, and grid plates 6 are installed to block debris. The water inlet 1.1 on the board 1 is connected to the water inlet conversion liner 2.2; the rear of the board 1 is reserved for the installation space of the power device 3, the forward and reverse conversion device 2 and the control device 4, which can be made into a split cover plate according to needs for easy assembly or overhaul and maintenance; the rear of the board 1 is provided with a fin 2.1 installation hole; two propeller 3.4 water outlets are arranged on both sides of the tail of the board 1, and a reversing device or a brake device can be added as needed. The outer dimensions and buoyancy of the two sides of the board body 1 are evenly distributed, and the buoyancy, hydrodynamic performance and control method of the front and back sides are the same, ensuring that the powered paddle board can be used on both sides.

[0044] From the above structural design, it can be seen that the size of the powered paddle board can be adjusted according to the rescue needs, which is convenient for quick operation. It is made of lightweight buoyancy material to ensure sufficient buoyancy and portability. Both sides can be used, which improves the rescue efficiency and adaptability.

[0045] like Figure 6 and 7 As shown, the forward-reverse conversion device 2 is arranged at the middle and rear part of the board body 1, and the forward-reverse conversion device 2 includes a fin 2.1, a water inlet conversion liner 2.2 and a linkage control mechanism 2.3. The linkage control mechanism 2.3 includes a drive motor 2.31 and a transmission assembly. The linkage control mechanism 2.3 is used to simultaneously link and control the actions of the fin 2.1 and the water inlet conversion liner 2.2. The forward and reverse conversion device 2 generally completes the action electrically under the control of the control device 4. The driving motor 2.31 is fixedly installed at an appropriate position on the board body 1. The liner and the fin 2.1 are driven to rotate at the required speed ratio through the transmission component to ensure that the rotation direction and angle of the water inlet conversion liner 2.2 and the fin 2.1 match. When the inlet 2.21 of the water inlet conversion liner 2.2 is aligned with the water inlet 1.1 of the board body 1 under the waterline, the draft fin of the fin 2.1 is at the maximum draft position, and the other fin is stored in the slot 1.3 of the board body 1; the forward and reverse conversion device 2 can also be manually operated. During operation, the exposed fin is pressed down into the slot 1.3 with force, and the draft fin can be pressed down to the draft position. At the same time, the water inlet conversion liner 2.2 is driven by the transmission mechanism to rotate and align with the water inlet 1.1 of the board body 1 under the waterline.

[0046] The rear part of the board body 1 is provided with slots 1.3 for installing the fins 2.1, and a seal is formed between the slots 1.3 and the board body 1. The fins 2.1 have symmetrical double fins at one end adjacent to the tail of the board body 1, and the other end of the fins 2.1 is rotatably connected to the slots 1.3 through a rotating shaft 2.35. The fins 2.1 are smooth and streamlined as a whole, without sharp edges and corners, with small shape resistance, and can provide sufficient righting torque.

[0047] Among them, the water inlet conversion liner 2.2 has a cylindrical shape and is installed in the reserved space of the plate body 1. The front end of the water inlet conversion liner 2.2 is sealed, and its rear end is rotatably connected to the water inlet main pipe 3.1. The connection part adopts a mechanical seal to ensure watertightness and smooth rotation. The inlet 2.21 of the water inlet conversion liner 2.2 is arranged on its tube wall, and the water inlet conversion liner 2.2 has a first linear flow channel 2.22 inside, the inlet of the first linear flow channel 2.22 is connected to the inlet 2.21, and the outlet of the first linear flow channel 2.22 leads to the water inlet main pipe 3.1. The water inlet conversion liner 2.2 and the two water inlets 1.1 on the front and back sides of the plate body 1 are provided with a second linear flow channel 2.23, and the second linear flow channel 2.23 is fixed on the plate body 1; when one of the second linear flow channels 2.23 is docked with the inlet 2.21, the other second linear flow channel 2.23 forms a seal with the tube wall of the water inlet conversion liner 2.2. The flow channel lines of the first and second linear flow channels are designed to effectively reduce the water inlet resistance and ensure the water inlet flow rate.

[0048] The input end of the transmission assembly is connected to the output end of the driving motor 2.31, and the output end of the transmission assembly is respectively connected to the fin plate 2.1 and the water inlet conversion liner 2.2. The driving motor 2.31 is used to drive the transmission assembly so as to control the fin plate and the water inlet conversion liner 2.2 to rotate synchronously. The transmission assembly includes a first gear pair 2.32, a transmission shaft 2.33 and a second gear pair 2.34. The input end of the first gear pair 2.32 is connected to the output end of the driving motor 2.31, and the output end of the first gear pair 2.32 is respectively connected to the rotating shaft 2.35 of the fin plate 2.1 and the input end of the transmission shaft 2.33. The output end of the transmission shaft 2.33 is connected to the input end of the second gear pair 2.34, and the output end of the second gear pair 2.34 is connected to the water inlet conversion liner 2.2. The rotation axis of the fin plate 2.1 and the rotation axis of the water inlet conversion liner 2.2 are perpendicular to each other. Among them, the specific structure of the first gear pair 2.32 and the second gear pair 2.34 can be selected conventionally in this field. It should be noted that in order to achieve the transmission relationship in two vertical directions, bevel gears or spiral bevel gears are usually used for power transmission. Whether it is a straight bevel gear or a spiral bevel gear, it is necessary to ensure that the two are correctly meshed during assembly, and the transmission ratio and direction meet the design requirements.

[0049] As can be seen from the above structural design, the forward-reverse conversion device 2 is controlled by electric or manual means, and can synchronously link the fin plate 2.1 and the water inlet conversion liner 2.2 to achieve flexible switching of the forward and reverse sides, and has good sealing and streamlined design to reduce resistance and provide effective righting torque. The design of the water inlet conversion liner 2.2 has the first and second linear flow channels, which can effectively reduce the water inlet resistance and ensure the water inlet flow rate. The transmission component structure is compact and reasonable, and the power transmission in two vertical directions is realized, making the forward-reverse conversion device 2 more efficient.

[0050] like Figure 8 As shown, the power device 3 is arranged in the reserved space at the rear of the board body 1, and has no exposed high-speed rotating parts, so it will not hit the drowning person and cause secondary injury. The power device 3 includes a water inlet main pipe 3.1, a water inlet distribution pipe 3.2, a propeller 3.4, a water outlet pipe 3.3, a propeller 3.4 motor, and a transmission shaft 2.33. A reversing or braking device can be installed as needed, which is controlled by the control device 4. The front end of the water inlet main pipe 3.1 is connected to the water inlet conversion liner 2.2. The water flows through the water inlet 1.1 of the board body 1 under the waterline, the water inlet conversion liner 2.2, and then flows into the water inlet main pipe 3.1 through the water inlet distribution pipe 3.2, and then is distributed to the two propellers 3.4, and finally discharged through the water outlet pipe 3.3. The propeller 3.4 motor is located on both sides of the rear of the board body 1, and is fixedly installed at an appropriate position on the board body 1 through a base. The propeller 3.4 is driven by the transmission shaft 2.33, and the transmission shaft 2.33 is installed at an appropriate position on the board body 1 through a bearing mechanism; the propeller 3.4 is arranged on both sides of the tail of the board, and is fixedly installed at an appropriate position on the board body 1 through a shell, and the water outlet extends to the outside of the tail of the board. The energy required by the power device 3 is supplied by the power supply device 5, and it works under the control of the control device 4. The rescuer can control the power device 3 through the operating interface or the operating handle. The power device 3 can also be equipped with a reversing or braking device as needed.

[0051] The control device 4 includes a floating state identification device, a control circuit, and a manipulation device. The floating state identification device is connected to the manipulation device, the forward and reverse conversion device 2 and the power device 3 through the control circuit. The floating state identification device is used to automatically identify the forward and reverse states of the powered paddle board. The forward and reverse conversion device 2 and the power device 3 can be manipulated according to the forward and reverse states of the powered paddle board to complete the forward and reverse switching and the port and starboard control switching of the thruster 3.4.

[0052] Among them, the operating device includes an operating interface or an operating handle. The operating interface is provided with functional modules such as front and back side switching, power device 3 operation, power supply control, etc., and other functions can also be set as needed to facilitate the rescuer to complete all operations. When a control handle is provided, the handle is connected to the control device, and functions such as starting, stopping, speed regulation, differential steering, reversing, braking, etc. can be realized as needed. Other functions can also be set as needed to facilitate the rescuer to control the power paddle board. A wireless remote control operating handle 4.2 and a wired remote control operating handle 4.1 can be installed as needed. The wired remote control operating handle 4.1 can be set with the required functions as needed. It is installed at an appropriate position at the tail of the board body 1 through an elastic rope 9, adopts a positive buoyancy design, and the main body is spring-shaped, which can automatically shrink and float to prevent entanglement, so that the rescuer can quickly grab and use it after the front and back sides are switched.

[0053] From the above structural design, it can be seen that the control device 4 is equipped with a floating state recognition device, which can automatically identify and switch the front and back sides and control the thruster 3.4 according to the state of the powered paddle board. The operating interface or operating handle is rich in functions, which is convenient for rescue personnel to operate and supports wireless remote control or wired remote control.

[0054] The power supply device 5 is installed in the reserved space in the middle of the board body 1, flush with the outer surface of the board body 1, with no exposed parts. After being fully charged, it can meet the needs of sailing for a long time. The overall watertight design allows convenient viewing of the battery status and capacity. It can be fully charged for a long time and can also be quickly disassembled and replaced to achieve continuous standby.

[0055] The dimensions of the powered paddle board are consistent with those of traditional paddle boards, and the total weight is relatively light. It can be made into various sizes according to needs. When in use, rescue team members can ride it in various postures and control the navigation by operating the joystick. When paddling with conventional hand paddles, the operation method is the same as that of traditional paddle boards. When used as equipment for direct rescue of drowning people, long boards with large reserve buoyancy are generally selected. Rescue team members can carry powered paddle boards on standby at the shore so that they can change the guard position at any time, or they can float on standby in the guard waters.

[0056] Based on the above structural design, the utility model provides a rescue method using a powered paddle board, comprising:

[0057] S1. Obtaining the location information of the drowning person;

[0058] S2. Rescue team members ride on powered paddle boards, turn on the propellers and quickly sail to the location of the drowning person;

[0059] Among them, the rescue team members quickly enter the water, get on the board, and aim in the direction. The rescue team members can ride in postures such as lying, riding, sitting, squatting, and kneeling to lower the center of gravity and improve navigation stability, and then turn on the thrusters to quickly move forward to carry out rescue;

[0060] S3. After sailing to a relatively close distance, slow down and approach the drowning person, then pull the drowning person so that his arms are placed on the paddle board with his armpits close to the side of the paddle board, then squat facing the drowning person with his feet as close to the edge of the opposite paddle board as possible, firmly grasp the drowning person's hands, and use the body force to flip the paddle board to rescue the drowning person onto the board;

[0061] S4. After getting on the board, adjust the drowning person's riding posture, then confirm whether the paddle board has completed the switch between the front and back sides, and then start the thruster to quickly take the drowning person away from the danger zone to complete the subsequent rescue steps.

[0062] It can be seen from the above design method that the powered paddle board is small and light in appearance, and rescue team members can ride in a variety of postures, which is conducive to quickly approaching the drowning person and improving the rescue speed and stability. The rescue method provided by the utility model guides rescue team members in detail on how to use the powered paddle board to quickly and accurately implement rescue. From obtaining location information to finally taking the drowning person away from the dangerous area, each step has a clear operation process, which greatly improves the success rate and safety of the rescue.

[0063] In addition, it should be noted that the specific structure, working principle, and possible control methods and spatial layout methods of the operating interface, operating handle, drive motor, thruster, floating state identification equipment, and power supply device in the utility model can be selected according to the conventional methods in the field, and should not be regarded as the innovative points of the utility model. For those skilled in the art, it is understandable that the utility model will not be further elaborated in detail.
