Abstract

The utility model discloses a negative-pressure drainage system for a powered surfboard. On the basis of a practical using state, a hollow cabin is arranged in a ship body of the powered surfboard; a thruster is fixed on the bottom surface of a stern of the surfboard; a drain pipe is further arranged; one end of the drain pipe is positioned at the bottom of the inner side of the cabin; the other end of the drain pipe extends into a water orifice at the tail end of the thruster by passing through the cabin; and the water outlet direction of the drain pipe is parallel and consistent to the water spray direction of the thruster. The cabin is communicated with the water orifice of the thruster through the drain pipe, a negative pressure is generated by the thruster during water spraying, and a pressure difference is formed between the generative pressure and the inside of the cabin, so that accumulated water in the cabin is completely drained out of the cabin along the drain pipe in time, the influence of the accumulated water on an engine is avoided, normal running of the surfboard is ensured, the accumulated water is prevented from flowing in the cabin simultaneously, running stability of the ship body is ensured, a user can operate conveniently, and the running stability and safety of the surfboard are enhanced.

Description

Power surf board drainage by suction system

Technical field

The utility model 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 get in the cabin, and water can make the driving engine cisco unity malfunction after in the cabin, accumulating too much, increases the weight of hull, and water flows in the cabin and can cause hull unstable, and the user is difficult for controlling.

The utility model content

In order to overcome above-mentioned defective, the utility model provides a kind of power surf board drainage by suction system, and this power surf board drainage by suction system can be in time, completely ponding in the cabin is discharged to out of my cabin, guarantees that driving engine normally moves even keel when guaranteeing to move.

The utility model for the technical scheme that solves its technical matters and adopt is: a kind of power surf board drainage by suction system; With actual running condition is 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 is provided with drain hose, and said drain hose one end is positioned at the inboard bottom of cabin; 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 the further improvement of the utility model, be benchmark with true travel direction, said drain hose one end is positioned at the bottom position of cabin afterbody.

As the further improvement of the utility model, said drain hose comprises flexible pipe and hard tube, and flexible pipe and hard tube sealing and fixing are communicated with, and hard tube extend in the angle of rake water injector.

As the further improvement of the utility model, said hard tube is a stainless steel tube.

The beneficial effect of the utility model is: the utility model is through 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 in time is discharged to ponding in the cabin out of my cabin completely along drain hose through pressure reduction and has gone; Avoided the influence of ponding to driving engine; Guaranteed the normal operation of surfboard, avoided ponding in the cabin, to flow simultaneously, guaranteed that hull operates steadily; Person easy to use controls, and has increased the stability and the safety of surfboard operation.

The specific embodiment

Embodiment: a kind of power surf board drainage by suction system is a benchmark with actual running condition, is 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, said drain hose one end is positioned at the inboard bottom of cabin 1, and 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, and in the process of moving, current spray at a high speed at the drain hose water outlet during through the awl mouth from propelling unit 2 ejection; Can form air negative pressure herein, thereby by ponding in the drain hose sucking-off cabin 1.

With true travel direction is benchmark, and said drain hose one end is positioned at the bottom position of cabin 1 afterbody, in motion; High back is low before the hull meeting; 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, so that draining to greatest extent.

Said drain hose comprises flexible pipe 31 and hard tube 32, and flexible pipe 31 is communicated with hard tube 32 sealing and fixing, and hard tube 32 extend in the water injector of propelling unit 2.

Said hard tube 32 is a stainless steel tube, prevents in the time of proof strength to get rusty.
