Abstract

The invention discloses a power surfboard negative pressure drainage system. The actual use state is utilized as a reference. A hollow ship cabin is arranged in a ship body of a power surfboard, a propeller is fixedly arranged on the bottom face at the ship tail of the surfboard, and a drain pipe is further provided. One end of the drain pipe is located at the bottom on the inner side of the ship cabin, the other end of the drain pipe penetrates the ship cabin to stretch into a water spraying port in the tail end of the propeller, and the direction of a water outlet of the drain pipe is parallel to and consistent with the water spraying direction of the propeller. Due to the fact that the ship cabin and the water spraying port of the propeller are communicated through the drain pipe, the propeller generates negative pressure when spraying water, and pressure difference is formed by the negative pressure and the pressure in the ship cabin, accumulated water in the cabin can be discharged to the outside of the cabin timely and completely along the drain pipe through the pressure difference. Effects of the accumulated water on an engine are avoided, normal operation of the surfboard is ensured, meanwhile the accumulated water is prevented from flowing in the cabin, ship body operation stability is ensured, a user can control the surfboard conveniently, and operation stability and safety of the surfboard are improved.

Description

Power surf board drainage by suction system

Technical field

The present invention relates to a kind of surfboard, especially a kind of power surf board drainage by suction system.

Background technology

Power surf board in use contacts with water, is difficult to avoid water to enter in the cabin, and water can make the driving engine cisco unity malfunction after accumulating too much in the cabin, increase the weight of hull, and water flows in the cabin and can cause hull unstable, and the user is difficult for controlling.

Summary of the invention

In order to overcome defects, the invention provides a kind of power surf board drainage by suction system, this power surf board drainage by suction system can be in time, completely the cabin internal water accumulation is discharged to out of my cabin, guarantees that driving engine normally moves even keel when guaranteeing to move.

The present invention for the technical scheme that solves its technical matters and adopt is: a kind of power surf board drainage by suction system, take real use state as benchmark, be provided with the cabin of hollow in the hull of power surf board, the stern bottom surface of surfboard is installed with a propelling unit, also be provided with drain hose, described drain hose one end is positioned at the bottom of cabin inboard, and the drain hose other end passes in the water injector that cabin extend into the propelling unit tail end, and the water outlet direction of drain hose is parallel consistent with angle of rake water spraying direction.

As a further improvement on the present invention, take true travel direction as benchmark, described drain hose one end is positioned at the bottom position of cabin afterbody.

As a further improvement on the present invention, described drain hose comprises flexible pipe and hard tube, flexible pipe and the fixing connection of hard tube sealing, and hard tube extend in the angle of rake water injector.

As a further improvement on the present invention, described hard tube is stainless steel tube.

The invention has the beneficial effects as follows: the present invention is by being communicated with cabin at drain hose with angle of rake water injector, propelling unit produces negative pressure when water spray, the inner pressure reduction that forms of this negative pressure and cabin, so just by pressure reduction the cabin internal water accumulation in time is discharged to out of my cabin completely along drain hose and has gone, avoided the impact of ponding on driving engine, guaranteed the normal operation of surfboard, avoided simultaneously ponding in the cabin, to flow, guaranteed that hull operates steadily, be convenient to the user and control, increased stability and the safety of surfboard operation.

The specific embodiment

Embodiment: a kind of power surf board drainage by suction system, take real use state as benchmark, be provided with the cabin 1 of hollow in the hull of power surf board, the stern bottom surface of surfboard is installed with a propelling unit 2, also be provided with drain hose, described drain hose one end is positioned at the bottom of cabin 1 inboard, the drain hose other end passes in the water injector that cabin 1 extend into propelling unit 2 tail ends, and the water outlet direction of drain hose is parallel consistent with the water spraying direction of propelling unit 2, propelling unit 2 afterbodys are awl shape, in the process of moving, when spraying by the awl mouth from propelling unit 2, current spray at a high speed at the drain hose water outlet, can form herein air negative pressure, thereby by drain hose sucking-off cabin 1 internal water accumulation.

Take true travel direction as benchmark, described drain hose one end is positioned at the bottom position of cabin 1 afterbody, in motion, hull can be front high rear low, can flow to stern after the water inlet in the cabin, so the end of drain hose in the cabin 1 of hollow is fixed on cabin 1 afterbody bottom, to greatest extent draining.

Described drain hose comprises flexible pipe 31 and hard tube 32, and flexible pipe 31 and fixing connection of hard tube 32 sealings, hard tube 32 extend in the water injector of propelling unit 2.

Described hard tube 32 is stainless steel tube, prevents from the time of proof strength getting rusty.
