In the embodiment shown in fig. 3 and 4, the two ground effect wings 7 are respectively arranged on the left side and the right side of the middle of the hull 3, one ends of the two ground effect wings 7 are hinged to the hull, the folding mechanism 10 is arranged between the two ground effect wings 7, and the folding mechanism 10 can drive the two ground effect wings 7 to be folded together synchronously.
In the embodiment shown in fig. 3 and 4, the folding mechanism 10 includes an upper mounting seat 10.7 and a lower mounting seat 10.6, which are vertically disposed, the lower mounting seat 10.6 is respectively hinged to two folding driving members 10.5 through a pin, the upper mounting seat 10.7 is respectively hinged to one end of two second folding rods 10.3 through a pin, the other ends of the two second folding rods 10.3 are respectively hinged to one end of a first folding rod 10.2 through an eccentric pin 10.9, the other end of the first folding rod 10.2 is hinged to a supporting plate 10.1 through a pin, and the supporting plate 10.1 is fixed on the ground effect wing 7. Two driving ends of the two folding driving pieces 10.5 are respectively hinged with a third folding rod 10.4 through a pin shaft, and the third folding rod 10.4 is fixed on the second folding rod 10.3. The two ends of the upper mounting seat 10.7 are symmetrically provided with supporting rods 10.8, the lower ends of the supporting rods 10.8 are fixed on the ship body 3, and the upper ends of the supporting rods 10.8 are fixedly connected with the upper mounting seat 10.7.

The force characteristic of the two-force lever is that the force component in the direction perpendicular to the lever axis is zero or very small, i.e. the force applied to the folding drive 10.5 is very small.

Because the first folding rod 10.2 and the second folding rod 10.3 adopt an eccentric self-locking mode, the self-locking can be released only through the external force action of the folding driving piece 10.5, namely, the first folding rod 10.2 and the second folding rod 10.3 rotate towards the unrestricted direction to destroy the dead point balance position by applying the external force through the folding driving piece 10.5, and then the self-locking is released, and at the moment, the ship body 3 becomes a four-body ship shape. When the ground effect wings 7 and the end plates 6 are required to be folded, the folding driving piece 10.5 is firstly retracted to drive the first folding rod 10.2 and the second folding rod 10.3 to be folded until the ship body 3 is in a catamaran shape.
In the embodiment shown in fig. 3 and 4, the WIG wing 7 is a swept-back trapezoidal wing structure, and provides the main aerodynamic lift as the main lift wing of the hull 3.

Ground effect wing 7 is connected end plate 6 dorsad 3 one sides of hull, and end plate 6 can provide the lateral stability for hull 3, can also increase the effective aspect ratio of ground effect wing 7 to improve the aerodynamic efficiency of ground effect wing 7.

In the embodiment shown in fig. 5, the wave pressing plate assembly 9 includes a wave pressing plate body 9.2, one end of the wave pressing plate body 9.2 is hinged to a first support 9.1 through a pin, and the first support 9.1 is fixed on the hull 3. The other end of the wave pressing plate body 9.2 is fixed with a second support 9.3, the second support 9.3 is hinged with a driving end of an adjusting piece 9.4 through a pin shaft, a body of the adjusting piece 9.4 is hinged with a third support 9.5 through a pin shaft, and the third support 9.5 is fixed on the ship body 3. The adjusting part 9.4 can adopt an oil cylinder, an air cylinder or an electric push rod. The wave pressing plate lift 9.2 is a rectangular thin plate, and the adjusting piece 9.4 can drive the wave pressing plate 9.2 to rotate up and down, so that the wave pressing plate 9.2 has different angles relative to waves, different hydrodynamic lift forces are generated at the stern of the ship body 3, the purpose of controlling the low head moment of the ship body 3 is achieved, and longitudinal stability and balance are achieved.
The folding mechanism 10 of the present invention will perform two functions during use: firstly, the folding of ground effect wing 7 and end plate 6 is realized, the deformation of ship type between catamaran and quaggar is accomplished to meet different sea condition conditions and navigational speed requirements. Namely, under the condition of high (severe) sea conditions, the ground effect wings 7 and the end plates 6 can fully exert the excellent wave resistance of the channel type double-body planing hull after being folded and separated from the water surface. Under the conditions of low sea conditions and high speed or ultrahigh speed, the unfolded ground effect wings 7, the end plates 6 and the channel type catamaran sliding boat body form a four-body boat shape, so that the unloading effect of the ground effect wings 7 at high speed or ultrahigh speed can be fully exerted, and the new concept four-body boat shape is different from other high-speed boats in that hydrodynamic lift force is continuously reduced in the process of changing from low speed to high speed. The reduced part of the hydrodynamic lift is compensated by the aerodynamic lift generated by the ground effect wing 7, which is the unloading function of the ground effect wing 7. The ground effect wing unloading technology is a technology for reducing the hydrodynamic lift of a ship body planing surface by utilizing the aerodynamic lift produced by the ground effect wing. Thus, the channel type double-body sliding ship body is gradually lifted, the water resistance of the ship body is reduced, and finally the requirements of high speed and even ultrahigh speed are met; and secondly, the transverse width of the channel folding wing ship is reduced, and the requirements of entering and exiting ports and channels and loading requirements are met. After the folding device 10 folds the wing 7 and the end plate 6 upwards, the width of the wing boat body is basically the width of the channel type double-body gliding boat body, only the height of the boat body is increased, but the passing and loading of the harbor channel are not influenced.
The four-hull ship of the channel folding wing ship is composed of the ground effect wings 7 which are laid down and are not folded, the end plates 6 and the channel type catamaran sliding ship body, the ship is transversely stabilized by hydrodynamic lift force generated by the end plates 6 which are in contact with water at low speed, and is transversely stabilized by aerodynamic lift force generated by the ground effect wings 7 at high speed of cruising. After the ground effect wings 7 and the end plates 6 are folded and retracted, a catamaran type of the channel folding wing ship, namely a channel type catamaran sliding ship body is formed, the catamaran type is transversely stable by hydrodynamic lift force generated by a left sliding surface and a right sliding surface at the bottom of the channel type catamaran sliding ship body, a concave channel in the middle can provide aerodynamic lift force, and a ram air layer cushion formed by the concave channel only improves the wave resistance of the catamaran type.
The longitudinal stability of the four-hull ship type of the channel folding wing ship is controlled and adjusted by a longitudinal balance system formed by a front wing 5, a ground effect wing 7 and a wave pressing plate assembly 9, wherein the front wing 5 and the ground effect wing 7 are jointly used for the longitudinal stable balance of aerodynamic lift, and an elevator 4 on the front wing 5 is used for adjusting the balance of the aerodynamic lift on the channel type two-hull planing ship body. The wave pressing plate assembly 9 on the stern is used for adjusting and controlling the balance of hydrodynamic lift on the channel type twin-hull gliding hull, and is mainly used for controlling the low head moment of the channel type twin-hull gliding hull by controlling different angles of the wave pressing plate during high-speed navigation, thereby achieving the purpose of reducing the longitudinal swing of the ship. The longitudinal stability of the catamaran version of the channel fold wing craft is then controlled and regulated entirely by the breakwater assembly 9.
The above description is intended to be illustrative, and not restrictive, the scope of the invention being indicated by the claims, and all changes that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
