A retractable three-axis intelligent search and rescue robot on water, including a central control platform, a suspension pole, a central telescopic pole and a lifesaving grid, the side circumference of the central control platform is hinged with the top of the suspension pole, and the suspension pole The bottom of the buoy is connected with the top of the buoy, and the bottom of the buoy is provided with a propeller. The middle part of the suspension strut is hinged with the top of the side telescopic rod, and the bottom of the side telescopic rod is hinged with the side wall of the hinge support. , the top of the hinge support is connected to the bottom of the central control platform through the middle telescopic rod, the side wall of the hinge support is hinged to the top of the bottom telescopic rod, and the bottom end of the bottom telescopic rod is connected to the outer ring of the life-saving net frame. The central control platform, the central telescopic rod, the hinge support, and the lifesaving net frame are arranged sequentially from top to bottom, and a camera is installed on the central control platform. This design not only has a good search and rescue effect, but also has the advantages of high navigation flexibility, high degree of automation, strong adaptability, and is suitable for rapid rescue on water, etc., and has broad application prospects.

The invention discloses an ocean observation device with an autonomous navigation function and belongs to the technical field of ocean observation equipment. The device comprises a floating body, a vertically-arranged spiral shaft is arranged in the center of the bottom of the floating body, and a bearing is arranged on the junction of the spiral shaft and the floating body; the end of the spiralshaft is cooperatively connected with a power generator in the floating body, a storage battery is connected to the power generator and connected with a controller, and a thruster is arranged at the bottom of the floating body; connection floating balls wind the side face of the floating body through connection ropes, and two or more floating balls are connected through connection rings. Multiplefloating balls of the side face of the floating body are connected not through connection rings. The device can provide sufficient electric energy and has the autonomous navigation function, the failure of the device does not easily occur, the device can continuously move and is high in navigation speed, and the observation device can acquire ocean observation images, sonar and other data for a long time.

The invention provides a method for manufacturing a mast made of a carbon fiber composite material, and relates to a method for manufacturing the mast. The invention aims to solve the problems of the prior metal mast has large mass, low strength and poor stability, and limits the quick sailing of ships. The method comprises the following steps: 1, designing and preparing a core mold; 2, impregnating dry carbon fibers in a resin mixed solution to obtain the carbon fiber composite material; 3, winding the carbon fiber composite material on the core mold layer by layer; 4, heating and solidifying the core mold; and 5, obtaining a rough rod of the mast made of the carbon fiber composite material after detaching the core mold, removing the processing length at two ends of the rough rod, removing burrs and obtaining the mast made of the carbon fiber composite material. As the mast of the invention is made of the carbon fiber composite material, the weight of the mast is 43.4 percent lighterthan that of the metal mast; and the carbon fiber composite material is intersected and wound layer by layer, so that the strength of the mast made of the carbon fiber composite material is improved,the stability of sailing ships is improved, and the sailing ships can be sailed quickly.

The invention discloses a submarine water flow propeller, which comprises a propelling system, a water suction device, a submarine or a warship or a civilian ship, a rudder and an ascending and descending handle, wherein flow guide pipes of the propelling system are fixedly arranged at the left side and the right side of center positions, near the lower ends, of the two sides of the submarine; the left side and the right side of the middle parts of the two sides of a warship or civilian ship base are fixedly connected with the flow guide pipes of the propelling system; the propelling system is communicated with the water suction device arranged at the front end of the submarine or the warship or the civilian ship, and comprises two groups of flow guide pipes; the back ends of the flow guide pipes are communicated with a tail spray opening and comprise a universal spray opening A, a universal spray opening B, a universal spray opening C and a universal spray opening D which are arranged at the left side and the right side and are electrically controlled; the spray opening A and the spray opening B are arranged at the left side and the right side of the front ends of the flow guide pipes; the spray opening C and the spray opening D are arranged at the left side and the right side near the front ends of the tail spray opening; the rudder is arranged in a control room of the submarine or the warship or the civilian ship and is used for controlling the advancing and leftward and rightward steering of the submarine or the warship or the civilian ship; and the ascending and descending handle controls the upward floating and the downward submergence of the submarine. The submarine water flow propeller can be used on the submarine or the warship or the civilian ship which are produced in future, and can also be modified on all of the existing aircraft; the work efficiency is improved; the manufacturing is simple; the installation and the maintenance are convenient; the cost is low; the energy sources are saved; and the practicability is very high.

The invention belongs to the field of ship engineering and discloses a wave-resistant ship which comprises a ship hull, two front wings, two middle wings, two rear wings, shaft sleeves, a rotating rod, limiting blocks and springs. Six shaft sleeves are fixedly mounted on each of two sides of the ship hull, two shaft sleeves are in a group, the tail of each of the front wings, the middle wings and the rear wings is fixed together with the rotating rod, the front wings are mounted on a group of shaft sleeves on the front portion of the ship hull through the rotating shaft, the middle wings are mounted on a group of shaft sleeves in the middle of the ship hull through the rotating rod, the rear wings are mounted on a group of shaft sleeves on the rear portion of the ship hull through the rotating rod, one limiting block is welded on each shaft sleeve, the limiting blocks can stop the front wings, the middle wings and the rear wings from exceeding rotating range, the springs are mounted between the shaft sleeves and the rotating rod, one ends of the springs are fixed on the shaft sleeves while the other ends of the same are fixed on the rotating shaft, and the springs play a role in damping and buffering. The wave-resistant ship is enabled to be capable of sailing more quickly and has the advantages of being strong in structure and light.
