Description

Anti-rollover device for ship

Technical Field

The utility model relates to a boats and ships, naval vessels or other ships on water especially relate to a device that is used for boats and ships to prevent turning on one's side.

Background

Ships with small volume and light weight are susceptible to sea waves and wind if running on the sea. Although the existing ship has certain automatic correction capability, under the condition of strong wind, once the ship turns on the side, the ship is difficult to automatically repair and correct, and the assistance of personnel on the ship or nearby ships is needed.

An unmanned ship is a full-automatic water surface robot which navigates on the water surface according to a preset task by means of satellite positioning and self sensing, and is widely used for automatically acquiring ocean data. Compared with other traditional ships, the unmanned ship is smaller in size, lighter in weight and more prone to being affected by sea waves and wind power to turn on one's side. Although the existing unmanned ship has strong capability of slightly inclining and returning to the right, the unmanned ship is often in a state of being far away from workers when being turned on side, and the unmanned ship can be rescued by the unmanned ship, so that the unmanned ship cannot continue to work, and can be damaged and abandoned, thereby not only causing loss, but also polluting the sea in the past.

The utility model discloses hope to provide a device that boats and ships were prevented turning on one hand stability is better for boats and ships are difficult for turning on one's side in the stormy waves, and on the other hand, even turn on one's side can be fast from moving back, makes boats and ships can continue normally to travel.

SUMMERY OF THE UTILITY MODEL

The present disclosure is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. The present disclosure is not intended to identify key features or essential features of the claimed subject matter; nor is it intended to be used as an aid in determining or limiting the scope of the claimed subject matter.

The utility model discloses a steady board bottom aggravates (lead pressing) and rearmounted slope is installed in the stern, makes the ship gravity center move backward, forms greatly to open the V-arrangement on the surface of water after being overturned by unrestrained or other external forces, makes the ship be in unstable equilibrium state to make the ship return fast, reach the purpose of preventing turning on one's side.

The utility model discloses a device of turning on one's side is prevented to boats and ships, including steadying board, lead pressing and propeller, wherein: the propeller is arranged at the bottom of the ship body near the middle position; the direction stabilizing plate is obliquely fixed right below the stern of the hull; the lead pressing is fixedly arranged at the bottom of the direction stabilizing plate. The installation position of the direction stabilizing plate enables the center of gravity of the whole ship to be located at the joint of the front edge of the direction stabilizing plate and the ship body, and a wide-open inverted V-shaped included angle is formed between the direction stabilizing plate and the bottom surface of the ship body. The propellers are double propellers and are respectively arranged on the left side and the right side of the middle of the bottom of the ship body. The position of the double propeller installation is in front of the center of gravity of the ship as a whole, with respect to the direction of ship advance.

Drawings

A more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.

FIG. 1 is a side view of a marine vessel according to the prior art;

fig. 2 is a side view of a ship to which a rollover prevention apparatus according to the present invention is added;

fig. 3 is a schematic view of the automatic aligning of the ship with the anti-rollover device according to the present invention under the rollover condition.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

Fig. 1 is a side view of a vessel according to the prior art, which comprises a hull, a stabilizer plate, lead weights etc.

In the prior art, a direction stabilizing plate and a lead pressing plate are arranged in the middle of the bottom of a ship, and the direction stabilizing plate is perpendicular to the plane of the bottom of the ship. After the ship overturns the bottom of the ship towards the sky, the structure continues to present stable balance on the horizontal plane and is difficult to overturn.

Fig. 2 is a side view of a ship to which a rollover prevention apparatus according to the present invention is additionally mounted.

The utility model discloses, adopt by leading two thrustors of installing the positive centre left and right sides in hull bottom, and the steady board is by the fixed hull bottom stern position department under the slope, and the lead pressing is fixed in steady board bottom by the installation, and steady board is certain contained angle with the hull bottom for the side view of whole hull is the shape of falling V of wide-open. The center of gravity of the whole ship moves backwards due to the backward movement of the direction stabilizing plate and the lead pressing plate, and the propeller is arranged in front of the center of gravity of the ship body when the direction of the bow of the ship is taken as the front.

The following description, with reference to fig. 3, describes the principle of automatic return of a ship, which is additionally provided with the device for preventing the ship from turning on one's side, under the condition of turning: the bottom of the direction stabilizing plate is pressed with lead and weighted and is arranged at the stern in a postpositive inclined manner, so that the gravity center of the whole ship moves backwards to the joint of the front edge of the direction stabilizing plate and the ship body. When the ship is overturned by waves, wind or other external forces, the whole ship is in a wide-open V shape when being inverted on the water surface, and the whole ship is in an unstable balance state. As indicated by the arrows in fig. 3. Under slight disturbance, the ship can be automatically overturned to quickly return to the right state, so that the ship can quickly recover to normal work.

The utility model discloses a device of turning on one's side is prevented to boats and ships has changed the mounted position and the angle of the steady board of hull bottom, has also adjusted the traditional mounted position of propeller in the hull bottom. The center of gravity of the ship is moved backwards, and the ship is made to present an inverted wide-open V shape. After the ship is overturned, the ship is in an unstable balance state, and is easy to automatically return to the original state without human intervention, so that the aim of preventing the ship from being overturned is fulfilled.
