TW201514060A - A boat with capability of preventing foreign matter from approaching to a bottom of the boat - Google Patents

Abstract

A boat with capability of preventing foreign matter from approaching to a bottom of the boat, comprises a front hull, a back hull connected to the front hull, a propeller, and a rudder plate. The back hull has a bilayer structure at a bottom thereof. The bilayer structure comprises a first bottom plate and a second bottom plate disposed above the first bottom plate. The first bottom plate and the second bottom plate cooperatively define a blind hole having an open end. The first bottom plate has a plurality of inlet pores. The propeller and the rudder plate are disposed inside the blind hole. Seawater is permitted to enter the blind hole via the inlet pores and to flow out from the open end of the hole, thereby avoiding foreign matter from entering the blind hole to entangle the propeller and the rudder plate.

Description

a ship that prevents foreign matter in the water from approaching the bottom of the ship

The present invention relates to a ship, and more particularly to a ship that prevents foreign matter in the water from approaching the bottom of the ship.

Vessels sailing in the water and fishing boats using fishing nets often cause propellers and rudders to fail due to drifting objects in the water (eg, water plants, garbage, debris, etc.) and fishing nets wrap around the propellers and rudder plates at the bottom of the hull. Operation, this not only increases the subsequent maintenance costs, but also greatly affects the quality and safety of navigation.

Therefore, there are already practitioners working to solve this problem. For example, Taiwan Patent Application No. TW 200804133 discloses a boat propulsion system comprising a recess formed in a hull, a moving impeller, a static impeller, an engine, an extended drive shaft, a water inlet grid, and a nozzle. . The front end of the recess has a minimum depth and the tail end has a maximum depth. The movable impeller is disposed at a rear end of the recessed portion, the static impeller is located behind the movable impeller, and the nozzle is disposed behind the static impeller, and the drive shaft extends from the engine disposed in front of the recessed portion to the movable impeller. And the inlet grid is provided One of the recesses is open. The water inlet grid is disposed on the opening of the recessed portion, so that only water can pass through without causing foreign matter in the water, even the fishing net to pass into the recessed portion, and the impeller and the static impeller disposed in the recessed portion are Important components such as the engine and the rudder of the ship.

However, the boat propulsion system disclosed in TW 200804133 is additionally installed on the vessel instead of being integrally formed with the vessel. In order to solve the problem of the above-mentioned foreign objects in the water and the components of the fishing net wound on the vessel, it is necessary to install the additional cost. The boat propels the system and increases the cost. Therefore, shipbuilders still need to develop vessels or vessel components that can reduce costs while solving the above-mentioned problems affecting navigation safety.

Accordingly, it is an object of the present invention to provide a means for preventing the drift of water and the propellers of the fishing boat from entanglement of the vessel to ensure safe navigation, and at the same time, to prevent the foreign matter in the water from approaching the bottom of the ship without additional cost of installing other components. ferry.

Thus, the present invention prevents a foreign object in the water from approaching the bottom of the ship, including a front hull, a rear hull, a propeller, and a rudder plate. The rear hull is located behind the front hull and is integrally formed with the front hull. One part of the bottom of the rear hull is a two-layer structure. The double layer structure includes a first bottom plate and a second bottom plate located above the first bottom plate and closedly connected to the front side of the first bottom plate. The first bottom plate and the second bottom plate together define a blind hole having a hole. The first bottom plate has a plurality of water inlet holes in fluid communication with the blind hole. The propeller is disposed in the blind hole and located above and behind the water inlet holes. The rudder plate is disposed in the blind hole and located behind the propeller.

The effect of the present invention is that the blind hole defined by the first bottom plate, the second bottom plate, the first bottom plate and the second bottom plate of the rear hull, and the fluid communication with the blind hole The water inlet hole, the propeller and the rudder plate are only allowed to enter the blind hole through the water inlet hole and are discharged from the hole through the water inlet hole, thereby avoiding foreign matter in the water (for example, water grass, garbage and garbage) Etc.) and the fishing net wraps the propeller and the rudder, thus ensuring safe navigation. In addition, the first bottom plate and the second bottom plate are components of a part (that is, the double-layer structure) constituting the bottom of the rear hull, so that the cost of installing other components is not required, and the shipbuilder is required to be reduced. the cost of.

Other features and effects of the present invention will be apparent from the following description of the drawings. FIG. 1 is a perspective view illustrating a preferred embodiment of the present invention for preventing foreign objects in the water from approaching the bottom of the ship; A cross-sectional view of the preferred embodiment is provided; and FIG. 3 is a rear cross-sectional view of the preferred embodiment.

Referring to Figures 1 and 2, a preferred embodiment of the ship of the present invention for preventing foreign matter from approaching the bottom of the ship includes a front hull 1, a rear hull 2, a propeller 3, and a rudder plate 4.

The rear hull 2 is located behind the front hull 1 and is integrally formed with the front hull 1. One part of the bottom 200 of the rear hull 2 is a two-layer structure 20. The two-layer structure 20 includes a first bottom plate 21 and a second bottom plate 22 located above the first bottom plate 21 and closedly connected to the front side of the first bottom plate 21. The first bottom plate 21 and the second bottom plate 22 together define a blind hole 24 having a hole 23. The first bottom plate 21 has a plurality of water inlet holes 211 in fluid communication with the blind holes 24. The propeller 3 is disposed in the blind hole 24 and located above and behind the water inlet holes 211. The rudder plate 4 is disposed in the blind hole 24 and located behind the propeller 3. Referring to FIG. 3, the first bottom plate 21 further has a V-shaped cross section, and the second bottom plate 22 has an arcuate cross section.

When the boat sails on the water surface, the first bottom plate 21 can only allow water to enter the blind hole 24 through the water inlet holes 211, and can block foreign matter (such as water plants, garbage, debris, etc.) and fishing nets in the water. The blind hole 24 is inserted into the blind hole 24 and the rudder plate 4 is wound.

In summary, the blind hole 24 defined by the first bottom plate 21, the second bottom plate 22, the first bottom plate 21 and the second bottom plate 22 of the rear hull 2, and the like The water inlet hole 211 of the blind hole 24 is fluidly connected, and the screw plate 3 and the rudder plate 4 are disposed in the blind hole 24, and only water is allowed to enter the blind hole 24 through the water inlet hole 211, and is discharged from the hole 23, The foreign objects in the water (for example, water plants, garbage, debris, etc.) and the fishing net are wound around the propeller 3 and the rudder plate 4, thereby ensuring safe navigation. In addition, the first bottom plate 21 and the second bottom plate 22 are components constituting a part of the bottom portion 200 of the rear hull 2 (that is, the double-layer structure 20), so that the cost of installing other components is not required, and the cost is lowered. The cost required by the shipbuilder can indeed achieve the object of the present invention.

However, the above is only the preferred embodiment of the present invention. The scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the present invention in the scope of the invention and the scope of the patent specification are still within the scope of the invention.
