It should be noted that in the description of the present invention, the terms "front", "back", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate directions or positional relationships based on those shown in the drawings, which are merely for convenience of description, but do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

A powered surfboard for disaster relief, as shown in fig. 1-3, which mainly comprises a board body 2, a handle body 3 and a general gasoline engine 1.

The plate body 2 is a main body of the surfboard for generating buoyancy. The plate body 2 can be made of engineering plastics, glass fiber reinforced plastics or carbon fibers. In order to prevent the side turning of the surfboard of the board body 2, wing plates 21 are arranged on two sides of the head of the board body 2, and an air outlet 23 is arranged above a waterline of the left wing plate 21. It should be noted that the air outlet 23 may be provided on the right wing plate 21. The wing plates 21 widen the width of the board body 2, so that the stability of the surfboard during driving is facilitated, the buoyancy of the head of the surfboard is increased, the waterline moves downwards, the air outlet 23 is higher than the water surface, and the water inlet of the air outlet 23 is prevented. The wing plate 21 is crescent-shaped, which is beneficial to reducing the resistance of water. An air duct is also arranged in the plate body 2 and consists of an air inlet duct 22 and an air outlet duct 25. The air inlet duct 22 is longitudinally disposed at the bottom of the plate body 2 and is communicated with the air inlet 33 of the air guide sleeve 32. The air outlet channel 25 is transversely arranged in the plate body 2 and is positioned above the air inlet channel 22. The air outlet channel 25 is approximately T-shaped, and two ends of the air outlet channel 25 are respectively communicated with the air outlets 23 on the wing plates 21 at two sides. The outlet 23 may be separately provided on the left or right of the wing 21. The rear portion of the plate body 2 is provided with a safety handle 6 connected with the waist of a human body, and a user can be hung and buckled on the safety handle 6 through a safety belt lock, so that the drowning danger caused by the separation of the user and the plate body in water is prevented.

The handle body 3 is positioned on the head part of the plate body 2 and comprises a handle and a cover body. The left handle is a fixed handle, the right handle is provided with an accelerator handle 31 and a flameout switch, and the accelerator handle 31 is used for controlling the rotating speed of the general gasoline engine 1. The cover body is an arc-shaped air guide sleeve 32 capable of reducing running resistance, a display device such as an instrument is arranged at the concave part of the leeward side of the air guide sleeve 32, and an air inlet 33 is arranged above the instrument and on the inner arc surface of the concave part of the air guide sleeve 32. The air inlet 33 is arranged at the concave part of the leeward side of the air guide sleeve 32 to prevent splashed spray from entering the air duct from the air inlet 33. The casing at the rear of the air guide sleeve 32 is provided with a starter handle for starting the general gasoline engine, and the general gasoline engine can be directly started by hand.

The general gasoline engine 1 is positioned at the communication position of the air inlet channel 22 and the air outlet channel 25, and the general gasoline engine 1 is sequentially connected with fan blades 4 and a propeller 5 through an output shaft 12. The propeller 5 is located outside the plate body 2 for generating propulsive force. The fan blades 4 are positioned in the air inlet duct 22 for generating wind power. When the general gasoline engine 1 works, the output shaft 12 drives the fan blades 4 and the propeller 5 to rotate together, and the fan blades 4 supply air to the general gasoline engine 1 while the propeller 5 generates propelling force. The fan blades 4 feed the engine 1 with ambient air, part of which is used to feed the engine 1, causing the engine 1 to burn and apply work, and the other part of which is used to cool the engine 1. The exhaust gas generated by the combustion of the general gasoline engine 1 is discharged from the exhaust pipe 11, enters the air outlet channel 25, is mixed with cooling air in the air outlet channel 25, and then is discharged from the air outlet 23. The rotation of fan blades 4 generates positive pressure in air outlet channel 25, and can prevent splashed spray from entering air outlet channel 25 from air outlet 23.

Since the fan blades 4 rotate coaxially with the propeller 5, when the rotation speed of the general gasoline engine 1 is increased, the driving speed of the surfboard is increased, and the blowing speed of the fan blades 4 to the general gasoline engine 1 is correspondingly increased. When the ventilation machine 1 is idling, the surfboard stops running and the fan blades 4 also stop blowing air to the ventilation machine 1. In order to discharge water which accidentally enters the air duct and avoid the damage of the water to the general gasoline engine 1, a water discharging plug 24 is arranged at the bottom of the air inlet duct 22.

The engine for the motorcycle is adopted as a power source in most of the existing oil-driven surfboards, and the engine for the motorcycle is provided with an unnecessary reduction gearbox, so that the size is large, the weight is heavy, and the portability of the surfboards is not facilitated. The cooling of the engine for the motorcycle is realized by air cooling or liquid cooling, the power source of the engine is from the motor, and the electric energy required by the motor is from the power generation of the engine. Obviously, the method increases the links of energy conversion and reduces the efficiency of energy conversion. And the utility model discloses a general gasoline engine 1 is as the power supply, and simple structure, light in weight can provide the required high rotational speed of screw 5, are favorable to the lightness of surfboard. The power output by the general gasoline engine 1 is utilized to directly drive the fan blades 4 to rotate to generate wind power to cool and radiate the general gasoline engine 1, so that the energy conversion link is reduced, the structure is simplest, and the energy utilization rate is highest.

The part of the utility model not detailed is prior art. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
