Detailed Description

In order to make the technical means, creation characteristics, achievement purpose and efficacy of the utility model easy to understand and understand, the utility model is further explained by combining with the specific figure below.

Aiming at the technical problem that the existing trimaran has low reliability, the utility model provides a small-size scientific investigation trimaran, see fig. 1-fig. 2, which is composed of a main hull 1, two auxiliary hulls 2, a through deck 3 and a built-up structure 4 four parts.

The main ship body 1 is a longitudinal continuous box body structure and is positioned on the center line of the ship body; the outside of the ship has a good streamline shape, and when the ship body runs in water, the friction between the ship body and water flow can be reduced to the minimum, so that the running speed of the ship is not influenced.

Referring to fig. 3-4, the main hull 1 is a hollow chamber, and is divided into a plurality of chambers by decks or longitudinal and transverse bulkheads, and the chambers inside the main hull are correspondingly provided with main power components; the main power assembly includes a diesel engine 11 and a main propeller 12.

Wherein, the diesel engine 11 is in driving connection with the main propeller 12 for providing the main propeller 12 with the power source for starting.

A main thruster 12 is provided at the aft end of the main hull 1 for providing thrust to the movement of the vessel; the main thruster 12 is composed of a control end and an execution end; the control end is arranged on a cabin deck of the main ship body 1 and is connected with the diesel engine 11; the execution end penetrates through the deck of the cabin and is placed in water, and the ship can be propelled to advance through the operation of the execution end and the power generated by water flow.

The type of the main propeller 12 is not limited herein, and may be a propeller or a water jet propeller, for example, and the specific application may be determined according to the actual situation.

The auxiliary hull 2 in the conventional small-sized trimaran has a narrow space, and a conventional diesel engine and a corresponding propeller shaft device cannot be arranged, so that the auxiliary hull in the conventional small-sized trimaran only takes the auxiliary hull as a floating body and cannot integrate the device.

For this reason, the sub-hull 2 given in this scheme is a structure capable of integrating the propeller 12 inside. This scheme sets up the perpendicular flexible propeller of direct current respectively in two assistance hulls, can realize stopping main propeller during operation, adopts two perpendicular flexible propellers of direct current of assistance hull to realize the low-speed, the low noise navigation.

Specifically, adopted two in this scheme to assist hull 2, its symmetry sets up in the both sides of main hull 1, can play the guard action to the main hull, and the space between assisting hull 2 and the main hull 1 is the air flue that vertically link up.

The length of the auxiliary hull 2 is about 50% -70% of the main hull 1, preferably 60% in the scheme, so that better stability can be provided for the trimaran, and the wave resistance of the trimaran can be improved in high sea conditions.

Two auxiliary ship bodies 2 are connected and provided with auxiliary power components, and each auxiliary power component comprises two auxiliary propellers 21, two motors and a generator 13.

The generator 13 is provided in the cabin of the main hull 1, connected to the diesel engine 11, and drives the generator 13 to generate electric power by the diesel engine 11.

The connection end of the generator 13 is connected with the auxiliary hull 2 and the electrical appliances in the upper building structure 4 through wiring harnesses respectively, and is used for supplying power to the auxiliary hull 2 and the electrical appliances in the upper building structure 4.

Two auxiliary propellers 21 are respectively arranged at the tail ends inside the auxiliary hulls, the two auxiliary propellers 21 are respectively connected with two driving motors, the two driving motors are respectively vertically arranged inside the two auxiliary hulls 2 and are respectively connected with the generator 13 inside the main hull 1, and the two motors are simultaneously driven by the generator 13 to respectively drive the two auxiliary propellers 21 to move. By the design, the main propeller 12 is used as power to drive sailing under normal conditions; when the main propeller 12 fails, the generator 13 is started to drive the auxiliary propeller 21 to make emergency sailing at a low speed of 3-5 knots to reach a safe area.

The auxiliary ship body 2 has narrow space, so that a conventional diesel engine and corresponding propeller shaft equipment cannot be arranged; therefore, the vertical electric propeller 21 can be preferably adopted as the main propeller in the scheme, the appearance is compact due to the fact that no diesel engine or middle shafting exists, the motor can be arranged vertically, the cable can be conveniently led out of the main ship body, and the main propeller can be integrated in the auxiliary ship body 2 by means of the characteristic of small overall appearance.

In this way, the generator 13 having a large profile for driving the auxiliary propeller 21 is disposed inside the main hull 1 without increasing the size of the main hull 1, and the auxiliary propeller 21 also employs an electric propeller having a small profile without increasing the size of the auxiliary hull 2, thereby ensuring that the cost of the hull is not increased and the sailing resistance is not increased.

The through plate 3 is located above the main hull 1 and the two subsidiary hulls 2 for connecting the main hull 1 and the two subsidiary hulls 2, thereby forming a continuous deck of a relatively large area.

The front area of the upper part of the through plate 3 is used for arranging the upper building structure 4, and the tail area of the upper part of the through plate 3 can be an open area which can be used for arranging scientific investigation equipment and can be used as a personnel activity area.

The upper structure 4 serves as a space for the operation of the vessel and the rest of the persons, and the specific arrangement and construction thereof are well known to those skilled in the art and will not be described in detail herein.

In the scheme, the main propeller 12 and the diesel engine 11 are placed in the main ship body 1, and the main propeller 12 is driven by the diesel engine 11 to drive the ship to sail as power under normal conditions; if the main thruster 12 fails, the generator 13 in the main hull 1 drives the vertical electric thruster 21 in the auxiliary hull 2 as power to drive the emergency sailing of the ship to reach the safe area.

Under the limiting condition of low cost, the scheme realizes larger deck area and better seaworthiness by using a small three-body ship; and the generator arranged in the main ship body is used for supplying power to the auxiliary propeller in the auxiliary ship body, so that the standby propelling function is realized, and the safety and the reliability of the whole ship are improved.
