Problems solved by technology
This technical solution is only suitable for small ships, and it is similar to the structure of a trimaran. The reason why there are many technical obstacles in the application of large ships is because: the floating body is independent of the hull, and the stress on the hull is much greater than that of a monohull. And concentrated on the connecting bridge between the floating body and the central main hull, the anti-wind and wave ability is poor. If it is converted to medium-sized and large-scale applications, it can only implement a stronger design for the connecting bridge, but it will increase the weight of the hull and sacrifice the load capacity. bottleneck
Therefore, as documented in the patent CN103330452B text, it is limited to the application of small survey ships on inland small rivers and lakes

Embodiment Construction
[0012] Rudderless flexible steering anti-rollover ship disclosed in this patent application, such as figure 1 , figure 2 In the shown ship, the cross-section of the bottom of the ship is concave-convex, and the concave parts are parallel to each other. From the bow to the stern, it is a waterway channel 1, and the opposite concave waterway channel 1 on both sides of the waterway channel 1 is a convex part. 2. In order to reduce sailing resistance, the convex part 2 is preferably streamlined, and a bulbous bow 5 is preferably provided at the head of the convex part 2, so that the ship of this scheme can reduce the impact of waves when sailing forward. The internal space of the concave-convex ship bottom is the space connected with the hull space 3, and the entire hull is formed by the support of the internal frame keel, which has an integral deck. 6 increases along with the quantity of waterway channel 1 increasing, so, this scheme is not limited in the design of ship size, ...

The invention provides an anti-rollover ship without rudders and capable of steering flexibly. The cross section of the bottom of the ship is concave-convex, the concave part of the bottom of the shipis a water channel through groove extending from the nose to the stern and parallel to each other, the water channel through groove is mounting space of propelling power devices, and the various propelling power devices are arranged in a matrix manner by taking a longitudinal axis of the ship as a symmetric central line. The technical scheme is widely suitable for small, medium, large, ultra-large and huge water steamship, and the anti-rollover ship steers rapidly and flexibly in a motorized manner, can rapidly steer at the original position on the water surface circularly without other auxiliary means, and meanwhile has the technical advantages of maintaining balance and stability of the ship body in storm and sharp turning and during lateral moving of the center of gravity of the ship body and steering and deflecting flexibly.
Description
technical field [0001] This patent application relates to water craft, such as boats, boats and the like. Background technique [0002] The rudder is the control device of the ship's navigation direction, and the propulsion paddle is the navigation power device. [0003] One type of ship rotates to change the direction of the propulsion blades to control the forward and backward direction of the ship, but the inertial resistance of the water in the conversion is large, and the sensitivity of direction conversion is poor; the other type of ship uses auxiliary propulsion power devices on both sides of the stern to assist steering , Improve steering maneuverability strategy. But with regard to the current technology, the steering control of the ship still mainly comes from the control of the rudder. [0004] Rudder operation steering has technical problems such as large turning radius, long steering time, and slow steering response. In addition, there is sideways deviation of...
