Description

An emergency collision avoidance device for a ship

technical field

The utility model relates to the field of shipbuilding, in particular to an emergency collision avoidance device for ships.

Background technique

In recent years, due to the rapid development of the shipping market and the utilization of marine resources, as the number of ships in the ocean increases, the obstacles in the sea will also increase. Although the existing ships are equipped with marine radar equipment, these equipments have no automatic anti-collision function. Early warning function, collision accidents are still high. In addition, ships are often affected by the weather, and the environment in the ocean is complex, resulting in a high number of collision accidents in the ocean.

When two ships meet, the distance is relatively close, which is less than the minimum safe distance of ships stipulated in the regulations. Faced with this emergency situation, it is often impossible to avoid collision by changing the rudder angle. In this emergency situation, it is necessary to quickly and effectively change the direction of the ship. The utility model designs an emergency collision avoidance device for ships, which not only quickly and effectively changes the navigation direction, but also is environmentally friendly.

detailed description

In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation of the utility model is described in detail with reference to the accompanying drawings.

As shown in Figures 1 to 3, the utility model is an emergency collision avoidance device for ships, which includes an umbrella cabin 1, an ejection umbrella, and a release device. Umbrella cabin 1 is welded together with the deck beam, and umbrella cabin door 1.1 is installed at one end of umbrella cabin 1, and umbrella cabin 1 is cylindrical barrel shape, and umbrella cabin door 1.1 is circular.

The ejection parachute includes a main parachute 2 and a guide parachute 3, the main parachute 2 is connected with the umbrella cabin 1 through the first parachute rope 2.1, and the guide parachute 3 is connected with the main parachute 2 through the second parachute rope 3.1.

The release device includes an electromagnet 4 and an ejection plate 6 abutting against the electromagnet 4 through a spring 5 , and the electromagnet 4 is connected with a storage battery 8 and a switch 9 arranged in the ship's cab through a cable 7 . The ejection plate 6 is made of steel.

The utility model is suitable for the situation that the distance between the ship and other ships or islands and reefs is very small (less than the minimum safety distance specified in the code) and the navigation direction cannot be changed quickly and effectively by rudder steering to avoid collisions. The working process of the utility model is as follows: when the ship is running normally, the switch 9 is closed, the umbrella hatch 1.1 is closed, the main umbrella 2 and the guide umbrella 3 are respectively shrunk in the first canopy cover 2.2 and the second canopy cover 3.2 and placed On the ejection plate 6 in the umbrella cabin 1, the spring is in a compressed state; when the distance between the ship and other ships or islands and reefs is very small (less than the minimum safety distance specified in the specification), the ship driver disconnects the switch 9, and the circuit leads Through, the magnetism of electromagnet 4 is eliminated, and there is no longer attractive force between electromagnet 4 and ejection plate 6, and guide umbrella 3 and main umbrella 2 open umbrella cabin door 1.1 and eject umbrella cabin under the elastic force of spring 5 1. The guide parachute 3 and the main parachute 2 are ejected from the cabin 1, the guide parachute 3 is fully inflated under the action of the airflow, and the main parachute 2 and the first parachute rope 2.1 are pulled out and straightened. At the same time, the first canopy cover 2.2 Fall off from the main parachute 2, and the main parachute 2 will be inflated and fully opened under the action of the airflow. When the air flows through the main umbrella 2, due to the effect of the main umbrella 2, the flow velocity decreases and the pressure increases at the front of the main umbrella 2, while at the back of the main umbrella 2, the flow velocity increases and the pressure decreases. A huge pressure difference is formed between the front and back, and then a huge aerodynamic resistance is generated on the main parachute 2. This force can form a rotational moment, so that the ship can quickly change the direction of navigation.

During the voyage of the ship, due to the uncertainty of the wind direction on the sea surface, the wind direction faced by the ship in an emergency is also uncertain. The following will describe how the ship avoids emergency situations in different wind directions. Collision avoidance by the collision device (interpretation of collision avoidance based on the principle of sailing to the right):

According to the real-time monitoring of the ship's navigation and wind direction, we can know the direction of the ship. When the ship is under the wind blowing from the port side in an emergency, as shown in Figure 4, in this emergency, since the distance between the two ships is less than the minimum safe distance of the ship stipulated in the regulations, at this time only the rudder is used to change the wind. The course cannot be successfully avoided. At this time, the driver turns on the switch of the bow emergency collision avoidance device, and the ejection parachute pops out of the parachute cabin. Under the action of aerodynamic force, a rightward force is generated, and a rotational moment is formed between the center of gravity of the ship and the The heading of the ship is to sail forward to the right, as shown in Figure 4, and the emergency avoidance is successfully completed.

As shown in Figure 5, when the ship receives the wind blowing from the starboard side in an emergency, in order to make the ship sail forward to the right in this case, a clockwise rotation torque is required. In this case, the stern emergency avoidance Touch the switch of the device, and the ejection umbrella pops out of the umbrella cabin. Under the action of aerodynamic force, a force to the left is generated, and a clockwise rotational moment is formed with the center of gravity of the ship, which changes the course of the stern and makes the ship sail to the right. Successfully complete emergency avoidance.

Embodiments of the present utility model have been described above in conjunction with the accompanying drawings, but the present utility model is not limited to the above-mentioned specific implementation, and the above-mentioned specific implementation is only illustrative, rather than restrictive. Under the enlightenment of the utility model, personnel can also make many forms without departing from the scope of protection of the purpose of the utility model and claims, and these all belong to the protection of the utility model.
