Portable powered surfboard and microlight-type motor boat machinery space in the processes such as startup, low speed and slowing-down brake submerges in water completely, inevitably have water and enter machinery space, particularly drainage by suction system in the past, water can enter machinery space in a large number from delivery piping, have a strong impact on the normal operation of driving engine, also can increase the weight of hull, cause speed-raising slack-off, water flowing in cabin can cause hull unstable, manipulation difficulty.
In sum, can there is water and pour in down a chimney from drain hose and enter machinery space in the drainage by suction system of prior art, ponding has a strong impact on normal operation and the result of use of driving engine.
Summary of the invention
The object of this invention is to provide and a kind ofly avoid water to pour in down a chimney, ensure that machinery space is without ponding and the unidirectional drainage by suction system of power surf board machinery space improving usability.
The technical scheme adopted for realizing above-mentioned purpose of the present invention is: the unidirectional drainage by suction system of a kind of power surf board machinery space, wherein: comprise the machinery space drain hose be communicated with the spray chamber of water jet propulsion pump by machinery space, the water inlet of this machinery space drain hose is positioned on the base plate of machinery space afterbody, and the water outlet of machinery space drain hose is arranged in the water chamber of water jet propulsion pump and consistent with the water spraying direction of water jet propulsion pump;
The machinery space drain hose of machinery space to water jet propulsion pump is provided with machinery space drain filter and machinery space check valve of water drainage.
Due to said structure, machinery space is connected with the water injector of water jet propulsion pump is unidirectional by drainage system, negative pressure is produced when water jet propulsion pump is sprayed water, this negative pressure and machinery space inside form pressure reduction, by this pressure reduction, the ponding in machinery space is discharged to out of my cabin in time completely along drainage system, simultaneously, in startup, low speed, and in the process such as slowing-down brake, machinery space is in below the water surface completely, water jet propulsion pump water injector is in barotropic state, check valve prevents current under positive pressure to the inflow of machinery space, it avoid large water gaging and enter machinery space, and completely ponding is discharged out of my cabin in time, ensure that driving engine normally runs, improve speed-raising performance, improve stationarity and the safety of hull during operation.
