Problems solved by technology

Based on the navigation environment of the inland river, due to the high speed of the hydrofoil boat, if the hydrofoil boat is applied to the inland river navigation, when it is necessary to stop the boat in an emergency, the existing hydrofoil boat has a slow stopping speed and cannot be realized. Rapid braking, the safety of navigation still needs to be improved; based on this, there is currently a design of adding a brake plate at the tail of the hull. At the rear of the propeller at the stern, due to the relatively concentrated pressure on the brake plate, stress concentration occurs at the same time. If the brake plate is damaged under a large stress, it will directly lead to brake failure, and the hull cannot achieve Emergency braking, the safety of sailing can not be effectively guaranteed

Embodiment 1

[0030] Such as Figure 1-Figure 6 As shown, the present embodiment provides a ship braking system, including a plurality of braking structures 2 installed on the bottom of the ship. The braking structure 2 includes a braking plate 2.1 and a driving device 2.2. One end of the braking plate 2.1 is hinged to the bottom of the ship. The driving device 2.2 drives the brake plate 2.1 to turn over in the direction in which the hull 1 travels.

[0031]In this technical solution, a plurality of braking structures 2 are arranged at the bottom of the ship. Since the driving device 2.2 can drive the braking plate 2.1 to turn over in the direction of advancing of the hull 1, the stopping resistance of the ship is improved, and the safety of the ship during navigation is guaranteed to a certain extent. Safety and quickness of emergency braking. And the arrangement of multiple brake structures 2, when the hull 1 is running, the brake plate 2.1 is in a state basically flat with the bottom of...

Embodiment 2

[0034] This embodiment is optimized on the basis of the above-mentioned embodiment 1.

[0035] The brake plate 2.1 is a curved plate, and the side of the curved plate with the concave surface 2.3 is facing the front of the hull 1, and the side of the curved plate with the convex surface 2.4 is facing the rear of the hull 1. The concave surface 2.3 of the curved plate is designed, because the concave surface 2.3 Towards the front of the hull 1, during the forward process, the concave surface 2.3 causes the water body to form a backflow, increases the resistance, and improves the braking effect; the convex surface 2.4 of the arc plate is designed, because the convex surface 2.4 faces the rear of the hull 1, when the brake plate 2.1 is in the In the braking state, the space B between the rear side of the brake plate 2.1 and the bottom of the ship can be reduced, thereby weakening the hydraulic cavity formed in the space B to further lift the hull 1, thereby weakening the resistanc...

Embodiment 3

[0037] This embodiment is optimized on the basis of the above-mentioned embodiment 2.

[0038] In order to further improve the braking effect, the concave surface 2.3 is provided with several grooves 2.5. The arrangement of the several grooves 2.5 makes the concave surface 2.5 present an uneven design as a whole, further increases the contact area between the concave surface 2.3 and the water body and forms backflow, thereby The forward resistance of the hull 1 is further increased, thereby realizing fast braking.

Abstract

The invention relates to the technical field of hydrofoil airships, and discloses a ship braking system and a multi-wing cargo ship with a braking function, the ship braking system comprises a plurality of braking structures installed at the ship bottom, each braking structure comprises a braking plate and a driving device, one end of each braking plate is hinged to the ship bottom, and the other end of each braking plate is hinged to the ship bottom; the driving device drives the brake plate to overturn towards the advancing direction of the ship body; according to the ship braking system and the multi-wing cargo ship with the braking function, the problem that an existing hydrofoil ship is poor in braking effect is solved.

Description

technical field [0001] The invention relates to the technical field of hydrofoil spacecraft, in particular to a ship braking system and a multi-wing cargo ship with a braking function. Background technique [0002] Traditional boats, because the bottom of the boat needs to sink into the water, and the resistance of the water is too large, so it will directly affect the speed of the boat. The hydrofoil boat is not subject to this limitation. The hydrofoil boat is named after the hydrofoil is installed under the hull. The principle of the hydrofoil boat is: the hydrofoil similar to the airfoil is installed under the hull, When sailing at high speed, the hydrofoil advances in the water and also gains lift, lifting the heavy hull out of the water, leaving only the hydrofoil, propeller and rudder to wait underwater. Among them, the hydrofoil structure of the hydrofoil boat can be divided into two types: split hydrofoil and fully immersed hydrofoil. The main feature of the split...
