The invention relates to a self-centering unmanned ship suitable for adverse sea conditions and a self-centering work manner of the self-centering unmanned ship, and belongs to the field of unmanned ship equipment and techniques. The unmanned ship comprises a main hull, a self-centering deck, equipment, a pipeline mast, a propeller, a radar, an air intake and exhaust system and a host machine system. According to the self-centering unmanned ship disclosed by the invention, the water-tight deck is designed, so that the hull of the unmanned ship has a self-centering function, the possibility of ship overturning of the unmanned ship is avoided, and additionally allocating self-centering equipment is not needed; besides, through the inner structure of the unmanned ship and the self-centering working manner, when a heeling angle of the hull exceeds a certain angle, a host machine and the air intake and exhaust system can be automatically turned off, so that the purpose that the whole ship is in a water-tight condition is realized; and when the heeling angle of the hull is returned to a small angle, the air intake and exhaust system and the host machine are automatically turned on, the mechanism is easy to operate, and the purpose of protecting a propelling system can be realized. During high-speed sailing in deep high sea, the unmanned ship can effectively and continuously work, and the unmanned ship is a reliable, economical and high-efficiency unmanned ship.

The invention provides a novel gaily-painted pleasure-boat. The novel gaily-painted pleasure-boat comprises a boat body, a rudder assembly, a roof structure and an engine room power device; the roof structure is manufactured and molded through wood, and the bottom part of the roof structure is fixedly mounted on a deck of the boat body; the rudder assembly is arranged in a cabin at the tail part of the boat body; a screw propeller is mounted at the tail part of the boat body and is driven to rotate through the engine room power device in an engine room; a control panel is arranged in the cabin; a power control system is arranged in the control panel and supplies power and controls a lighting system and the engine room power device in the boat body through a charging-discharging system. The novel gaily-painted pleasure-boat has the advantages of being novel in style, reasonable in structure, good in operation effect, low in energy consumption, and high in controllability.

The invention discloses an anti-winding device of an unmanned boat propeller thruster. The anti-winding device comprises a rotary shaft; the left end of the rotary shaft and an external power output shaft are connected through a coupling, and four propellers are mounted at the right end of the outer side face of the rotary shaft at equal angles; an annular protrusion is arranged on the right sideof the outer side face of the rotary shaft, and protrusion positioning spiral insection is formed on the annular protrusion; a movable cutting pipe sleeves the rotary shaft, and embedded spiral insection is formed on the inner wall of the movable cutting pipe; and part of water suspended solids is blocked by a U-shaped shielding rod and a circular ring, left side cutting knives, arc-shaped knivesand right side cutting knives can move in a left-right reciprocating mode in the radial direction of the rotary shaft so as to cut the wound suspended solids, and power of left-right moving of the movable cutting pipe is only assisted by rotary motion of the rotary shaft. The anti-winding device of the unmanned boat propeller thruster is simple in structure, low in cost and good in clearing effecton the wound suspended solids, and thus normal navigation and production work of an unmanned boat are ensured.

The invention relates to the field of ocean engineering equipment, in particular to an ocean roll-roll shipment heavy lift vessel which is composed of a vessel body and cranes. A deck of the vessel body is provided with a super barrier-free deck region, the side face of the deck is provided with the cranes, and the cranes are each composed of a lifting arm, a crane shell, a base and a cab. Drive devices of an ascending mechanism, a pitching mechanism and a rotation mechanism and electrical equipment are arranged in each crane shell. The ascending mechanism, the pitching mechanism and the rotation mechanism are arranged on each crane shell. The ocean roll-roll shipment heavy life vessel is mainly characterized in that the effect that lifting loading and rolling loading of heavy cargos are achieved at the same time is unprecedented in the world, the advantages of global non-restricted waters, river-ocean combined transportation and shallow draft and the advantage that heavy cargos can be craned by the small vessel are achieved, the economy of bulk shipping is increased greatly, and the ocean roll-roll shipment heavy life vessel is complete in function and leading in the world.

The present invention relates to the technical field of ships, and in particular to a method for early warning and deicing of ice accumulation on ships, which includes the following steps: S1. Installing a deicing device on the ship's side; S2. Installing a deicing device on the ship's side. A plurality of sensors are arranged on the outside; S3, the sensor collects the ice accumulation information on the outside of the side of the ship, and transmits the ice accumulation information to the control system; S4, when the ice accumulation information is higher than the deicing threshold, The control system provides early warning and controls the deicing device to perform deicing operations. When the ship sails in the Arctic region, the present invention can give an early warning to the ice accumulation situation of the ship, and can remove the ice accumulation to ensure the normal navigation of the ship.

The invention discloses a flood control weir. The weir comprises a main dam stretching across a river and further comprises a base dam, a gate and a driving device, wherein the base dam stretches across the upstream position of the main dam, and the base dam is lower than the main dam; the gate is rotationally arranged at the upper end of the base dam; the driving device is connected with the gate and is used for driving the gate to rotate towards the upper side of the base dam or the lower side of the base dam. With the adoption of the weir, the base dam is arranged above the main dam, and when the main dam is dismounted, the base dam can intercept a certain amount of water flow, so that flood influencing the downstream position is avoided; besides, the base dam is lower than the main dam, and thus ship sailing can be guaranteed.
