[0025] When in use, the interchangeable hydrofoil power device can simultaneously meet the use requirements of unpowered hydrofoil, power-assisted hydrofoil and electric hydrofoil. When the player wants to experience the unpowered hydrofoil, the electric propeller 7 can be directly removed, although the battery 2 and the controller 3 are still integrated inside the stand 1, but they will not affect the experience of the unpowered hydrofoil gameplay. When the player wants to experience the power-assisted hydrofoil, the surfboard 11 is installed on the end of the stand 1 close to the electric propeller 7 through the board seat 9. When installing, first connect one end of the control cable 8 to the signal connector 6 through the hole in the middle of the board seat 9, and then fix the board seat 9 and the surfboard 11 in turn. At this time, the control cable 8 at the end is embedded in the groove opened at the bottom of the surfboard 11. Further bend the control cable 8 to make it close to the front end of the stand 1. Finally, install the wing seat 10 and the hydrofoil blade 12 in turn at the other end. At this time, put the hydrofoil into the water, and the electric propeller 7 is above the stand 1. The user stands on the surfboard 11 and starts the electric propeller 7 through the remote control, and then gradually speeds up. When the hydrofoil blade 12 moves in the water, it rises upward when the speed increases to a certain extent by using the Bernoulli theorem of fluid mechanics. When the stand 1 rises to a certain height, the electric propeller 7 is out of the water. Further, the user stops controlling the electric propeller 7 through the remote control and then relies on his own strength and skills to continue driving the hydrofoil. When the player wants to experience the electric hydrofoil, the hydrofoil blade 12 is installed on the end of the stand 1 close to the electric propeller 7 through the wing seat 10. When installing, first connect one end of the control cable 8 to the signal connector 6 through the hole in the middle of the wing seat 10, and then fix the wing seat 10 and the hydrofoil blade 12 in turn. At this time, the control cable 8 at the end is embedded in the groove opened at the bottom of the hydrofoil blade 12. Further bend the control cable 8 to make it close to the front end of the stand 1. Finally, install the board seat 9 and the surfboard 11 in turn at the other end. At this time, put the hydrofoil into the water, and the electric propeller 7 is below the stand 1. The user stands on the surfboard 11 and starts the electric propeller 7 through the remote control, and then gradually speeds up. When the hydrofoil blade 12 moves in the water, it rises upward when the speed increases to a certain extent by using the Bernoulli theorem of fluid mechanics. However, since the electric propeller 7 is below the stand 1, even if the stand 1 rises, the electric propeller 7 is always underwater. At this time, the user only needs to control the electric propeller 7 through the remote control, and the hydrofoil can always be driven quickly under the action of the electric propeller 7, without relying on his own strength and skills. In the use process, the stand 1 will not completely separate from the water surface, so the stand 1 can always be cooled by the water flow, and the battery 2 and the controller 3 installed inside the stand 1 can be cooled in time. The stand 1 is provided with a charging connector 5 and a signal connector 6 at both ends, that is, the electric propeller 7 can be installed at any end of the stand 1 to make it more durable.
[0026] In summary, the interchangeable hydrofoil power device hides the battery 2 and the controller 3 inside the hollow column 1 with a cross section similar to a shuttle, and the column 1 has good heat dissipation effect when moving in water, so that the heat generated by the battery 2 and the controller 3 can be dissipated in time. The plate seat 9 and the wing seat 10 at both ends of the column 1 can be installed by changing positions, and the electric propeller 7 is not installed at the middle position of the column 1 but at the rear end close to one end, so that changing the installation positions of the plate seat 9 and the wing seat 10 can change the distance between the hydrofoil blade 12 and the electric propeller 7. When the electric propeller 7 is close to the hydrofoil blade 12, the electric propeller 7 is always underwater during use and can always provide power. When the electric propeller 7 is away from the hydrofoil blade 12, the electric propeller 7 only provides boost in the early stage but is separated from the water surface in the later stage and no longer provides power. The electric propeller 7 can also be directly removed and not used at all, so that different functions can be realized. Since the battery 2 and the controller 3 are integrated in the column 1 and the column 1 is provided with the signal connector 6 connected thereto at both ends, the length of the control cable 8 exposed outside the electric propeller 7 is small, and the control cable 8 can maintain its shape after bending so that it always adheres to the front end of the column 1, thereby reducing resistance and facilitating navigation.
[0027] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
