Abstract

The utility model provides an automatic drainage mechanism of a surfboat. The automatic drainage mechanism of the surfboat comprises a drain hole formed in the bottom of the surfboat and an arc-shaped water baffle arranged outside the drain hole in the bottom of the surfboat, wherein a middle transition space which is arranged outside the drain hole and forms an opening towards the tail of the surfboat is formed by the arc-shaped water baffle on the bottom of the surfboat, a weather bar is arranged on the back portion of the opening by the drainage mechanism, and a drainage gap is formed between the weather bar and the opening. By the adoption of the fluid mechanics principle, when the surfboat enters into water, the water baffle and the weather bar can be cooperative to play a role of drainage and water retaining. By the adoption of the air compression principle, the middle transition space can withstand water to enable the water to hardly flow back into the surfboat from the outside of the surfboat through the drain hole. By the adoption of principle of inertia, when the surfboat is traveled, water in the surfboat automatically discharge according to the route of the drain hole, the middle transition space and the opening, so that automatic drainage function can be achieved when the surfboat is traveled, row is more labor-saving, and row speed is improved.

Description

The automatic draining mechanism of surfboat

Technical field

The utility model relates to the automatic draining mechanism of surfboat.

Background technology

Surfboat is a kind of by drawing the single driving of passerby, the ship that single-blade paddles.This class ship residing environment that travels is comparatively complicated.In paddling, it is common phenomenon that water is splashed in the ship, and in time discharging ponding in the ship is a key factor that improves moving velocity and save muscle power.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of automatic draining mechanism of surfboat, can be at the ship middle realization automatic drainage function that travels.For this reason, the utility model is by the following technical solutions: it comprises the drain gutter of being located at the bottom of the surfboat, outside the drain gutter at the bottom of the surfboat, be provided with arc-shaped watertight shutter, described arc-shaped watertight shutter form at the bottom of the surfboat one be in outside the described drain gutter to the uncovered middle transition space of ship tail direction, described drainage mechanism is provided with weather bar at described uncovered rear, and weather bar and described gap between uncovered form drainage gap.

On the basis of adopting technique scheme, the utility model also can adopt following further technical scheme:

Described weather bar be shaped as stream line pattern, the profile of described arc-shaped watertight shutter is for conical or have tip and the arc of expansion gradually backward, and the length of weather bar is long than arc-shaped watertight shutter.

The head of described weather bar is more described uncovered smaller or equal.

Described drain gutter is in draws passerby's bench between the step tread plate in the surfboat.

Owing to adopting the technical solution of the utility model, the utility model can utilize fluid mechanics principle, so that under surfboat during water, drain board and weather bar can coordinated play draining and dash effect, the middle transition space can utilize the air compressing principle to withstand water, shipwreck is entered in the ship to pour in down a chimney through drain gutter from the outside, and in ship travels, can utilize principle of inertia again, with the water in the ship automatically according to drain gutter, the middle transition space, uncovered circuit and discharging, thus can at the ship middle realization automatic drainage function that travels, in time discharge ponding in the ship, make and paddle more laborsavingly, improve the speed of paddling.

Description of drawings

Fig. 1 is the birds-eye view of configuration surfboat of the present utility model.

Fig. 2 is the ship underneath side elevation view of configuration surfboat of the present utility model.

Fig. 3 for the ship of configuration surfboat of the present utility model at the bottom of at the schematic diagram from ship Caudad ship is first when observing.

The specific embodiment

With reference to accompanying drawing.The utility model comprises is located at the bottom of the surfboat 10 drain gutter 1, outside 10 drain gutter 1 at the bottom of the surfboat, be provided with arc-shaped watertight shutter 2, described arc-shaped watertight shutter 2 is in middle transition space 20 to ship tail direction uncovered 21 that is in outside the described drain gutter 1 of 10 formation at the bottom of the surfboat, described drainage mechanism is provided with weather bar 3 at described uncovered 21 rear, and the gap between the weather bar 3 and described uncovered 21 forms drainage gap.

Described weather bar 3 be shaped as stream line pattern, the profile of described arc-shaped watertight shutter 2 is for conical or have tip and the arc of expansion gradually backward, and the length of weather bar 3 is long than arc-shaped watertight shutter 2.

The head of described weather bar 3 more described uncovered 20 is smaller or equal.

Drain gutter 1 is in draws passerby's bench between the step tread plate 4 in the surfboat.

The direction of arrow among Fig. 3 is outside water inlet direction.

The direction of arrow among Fig. 2 is the first direction of ship.
