When installed, the inflatable cabin 1 and the power cabin 2 are integrally connected and serve as a hull of a surfboard. For the convenience of carrying, the power cabin 2 is detachably connected with the inflatable cabin 1 to form an integral body. Since the inflatable cabin 1 can be inflated and deflated, the deflated inflatable cabin 1 can be detached from the power cabin 2, and the independent inflatable cabin 1 After deflation, it can be folded and folded, and the volume of the inflatable cabin is very small compared to the hull as a whole, which is very convenient to carry, and the surfboard is powered by the power cabin, and the speed provided by the power drive brings the surfboard more.

In this embodiment, two sets of power devices are provided, so that the power is more powerful and more entertaining, and when one set is not working, the other set can work to ensure that the surfboard can be returned to the shore and used. More secure. Correspondingly, the surfboard is equipped with two sets of main heat sinks and two sets of sub heat sinks. Of course, only one set of power units can be operated in the entire power cabin. At this time, the matching structure and control mode can be adjusted accordingly.

The surfboard is provided with a control system for controlling the operation of the entire surfboard. The control system includes a control main board 54 and a hand-held remote controller 57 electrically connected to the control main board 54, and the control main board 54 is disposed in the power cabin 2, and The hand controller 57 is disposed on the inflatable cabin 1.

The intelligent alarm device 7 can also be used for a handle when driving. In this embodiment, two sets of hand-held controllers 57 are provided, which are respectively provided with buttons of different functions, which are also respectively used for controlling devices, mechanisms or components such as the power device, the water-fighting device 8, and the intelligent alarm device 7 to be described below. The use of two sets of hand-held controllers 57 makes it easier to operate and control the surfboard, which is more maneuverable and more entertaining. The handheld controller does not use its control buttons and control functions, and it is also the handle that the surfers hold.

In this embodiment, in order to ensure the long-term normal operation of the power cabin, the heat dissipation speed, heat dissipation efficiency and service life of the engine and the entire power cabin are effectively improved, and the main heat sink 6 and the auxiliary heat sink 59 are provided in the power cabin 2, the main The heat sink 6 is a liquid conduction cooling type heat sink, and the auxiliary heat sink 59 is an integrated solid conduction cooling type heat sink. In the present embodiment, the main heat sink 6 utilizes a flow of water to conduct cooling. The main heat sink includes a cooling inlet pipe 61, a cooling water outlet pipe 62, a water delivery pipe 63, and a main heat dissipation block 64. The main heat dissipation block 64 is internally provided with a hollow through hole. a cooling water passage (not shown) is used for the water supply flow, and the cooling water passage is adapted to be connected to the cooling water inlet pipe 61, the cooling water outlet pipe 62, and the water delivery pipe 63, and one end of the cooling water inlet pipe 61 is The end of the pump spray housing 521 communicates with the other end of the cooling water passage inlet of the main heat sink block 64.

Thus, since the main heat sink 6 is specifically provided, the heat dissipation speed inside the power cabin, particularly the engine 51, is faster and more efficient, and the service life of the engine 51 is greatly extended; the main heat sink 6 utilizes the propeller 55 and the deflector 56. The force acting on the water flow, that is, the pressure of the water sprayed from the water outlet of the pump is used as a power, so that the water flows through the cooling water inlet pipe 61 into the cooling water passage inside the main heat dissipation block 64 and then flows out of the power cabin 2 through the cooling water outlet pipe 62, so that the engine and even the engine The heat generated in the entire power cabin can be effectively dissipated mainly through the water flow passage composed of the cooling inlet pipe, the cooling water channel of the radiator block and the cooling water pipe; in addition, no additional power device is required to drive, that is, no new energy is consumed. Environmental protection and energy conservation.

The sub heat sink 59 is an integrated solid conduction cooling type heat sink. In the embodiment, the solid mainly refers to a solid made of a metal heat conductive material.
