Description

Technical Field

[0002] The marine folding wing is a device with special uses on ships. It is usually made of high-strength metal materials or composite materials and has the characteristics of being strong and durable. The marine folding wing mainly includes structures such as foldable wing panels, connecting mechanisms and driving devices. When a ship encounters wind and waves during navigation, unfolding the folding wings can increase the lateral stability of the ship. The lift and resistance generated by the wing panels in the water can offset part of the force of the waves and reduce the roll and pitch of the ship, making the ship travel more smoothly. The folding wings can change the hydrodynamic characteristics of the ship in the water, thereby affecting the maneuverability of the ship. When turning, unfolding the folding wings on one side can increase the resistance on that side and make it easier for the ship to turn.

[0019] The present invention is described in detail below according to the accompanying drawings. The folding wing of the marine solar panel of the present invention comprises a folding wing fixing seat 1 arranged on both sides of the hull 5 and a folding wing 2 hingedly arranged on the folding wing fixing seat 1.

The folding wing drive assembly 7 is a connecting rod drive structure, which can reduce the occupied space and weight of the folding wing drive assembly 7 under the premise of the same driving amplitude.

The lower folding wing 21 includes a lower wing mounting plane 211 and a lower wing curved surface 212. The upper folding wing 22 includes an upper wing mounting plane 221 and an upper wing curved surface 222.

The lower wing curved surface 212 and the upper wing curved surface 222 form a streamlined structure after the folding wing 2 is closed, which can effectively reduce the wind resistance of the folding wing 2.

[0022] The folding wing 2 also includes a base 23 arranged at the end of the lower folding wing 21, and the folding wing driving assembly 7 is transmission-connected with the base 23 to drive the folding wing 2 to rotate horizontally; the base 23 includes a rotating base 231, a power base 232, a connecting plate 233 and a folding wing mounting plate 234, the folding wing mounting plate 234 is connected and fixed to the end surface of the lower folding wing 21, and a protruding connecting plate 233 is provided on the folding wing mounting plate 234, and a rotating base 231 and a power base 232 are provided on the connecting plate 233; the rotating base 231 is provided on the coaxial hinged seat 11 on the folding wing fixing seat 1, and the base 23 can rotate on the coaxial hinged seat 11, and the power base 232 is transmission-connected with the folding wing driving assembly 7.

In an embodiment of the present invention, when the folding wing 2 is driven to an approximately vertical state of the hull 5, the driving rod 71 and the driving block 72 are approximately in the same straight line, which can achieve self-locking of the rotation of the folding wing 2, thereby improving the supporting force of the driving rod 71 and the driving block 72 on the folding wing 2 and reducing the squeezing of the power cylinder 75 by the folding wing 2 when subjected to external force.

When the power cylinder 75 drives the power pin 751 to move linearly along the vertical long hole 732, the power pin 751 also slides along the arc hole 722 and drives the driving block 72 to swing. Further, the structure of the arc hole 722 of the present invention is an arc extension shape, which reduces the resistance of the power pin 751 sliding in the arc hole 722, and eliminates the situation that the power pin 751 is stuck in the extreme positions at both ends of the arc hole 722, so that the power output of the power cylinder 75 at the extreme position of the folding wing 2 is more stable.
