Description

Technical Field

[0002] Ship safety resistance, more specifically, refers to the ship's brake system, anti-roll device or anti-collision equipment, all of which are designed to ensure the safety of the ship during navigation. For example, anti-roll fins or anti-roll tanks are devices used to reduce the shaking of the ship in the waves; while the anchor and anchor chain system can be used as a safety measure to fix the ship; in an emergency, the ship's brake system (such as reverse thrusters) can help stop the ship quickly.

[0003] The traditional safety drag device for ships is not easy to adjust the tilt angle when braking, and the braking resistance is not easy to adjust, which can easily lead to excessive resistance and the inability to accurately stop at the destination, resulting in poor flexibility in use.

The resistance plate of the device is limited and rotated by a second bearing. Two submersible low-speed motors at the rear end of the second bearing work, and a large gear is driven to rotate by two small gears, so that the resistance plate can be rotated. The inclination angle of the resistance plate can be adjusted by controlling the operation of the two submersible low-speed motors to control the braking force and resistance, thereby improving the flexibility of use. The brakes can be appropriately adjusted according to the distance of the ship from the destination to accurately stop at the destination.

[0010] Furthermore, a third bearing is rotatably disposed on the rear end surface of the second rotating shaft, and second support frames are fixedly disposed on both upper and lower ends of the third bearing;

[0011] Through the above technical solution, the third bearing and the control compartment are connected via two support frames and hydraulic telescopic columns.

[0012] Furthermore, the opposite sides of the two hydraulic telescopic columns are rotatably connected to the two second support frames respectively;

[0013] Through the above technical solution, the resistance plate can be controlled to tilt around the first rotating axis by controlling the two hydraulic telescopic columns to work separately.

[0014] Furthermore, first bearings are fixedly arranged on both sides of the front end of the control compartment, and the two first rotating shafts are rotatably connected to the two first bearings respectively;

[0015] Through the above technical solution, the first bearing limits the rotation of the first rotating shaft.

[0016] Furthermore, three mounting plates are fixedly arranged at both ends of the controller, and mounting holes are opened in the middle of the six mounting plates;

[0018] Furthermore, the controller and one side of the resistance plate are in an arc shape from large to small;

[0019] Through the above technical solution, the controller and one side of the resistance plate are designed in an arc shape from large to small, which can reduce the resistance generated by the resistor when the ship is sailing normally.
