DETAILED DESCRIPTION

[0017] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0018] The present invention is different from ordinary steel-made ships that make the hull hollow to gain buoyancy. Instead, it has a flat-bottom design. The middle part of the hull 8 and the edges of the front, rear and both sides are all made of high-strength steel or alloy steel, which has good bending resistance. The middle part is a main beam structure, which is distributed along the longitudinal direction of the hull. It is the core bearing structure of the scaffold. There is also a crossbeam structure connecting the main beam and providing lateral support. The distance between the beams is evenly arranged. Side beams are installed on both sides of the main beam to further improve the overall bearing capacity. Load-bearing wheels 3 are designed at the bottom of the hull 8. The load-bearing wheels are wide steel wheels, which are convenient for moving on the ground or inside the mother ship. There is a separate steering wheel at the front. In order to reduce noise and shock, the driving is more stable. The outer ring of the wheel that contacts the ground adopts a layer of wear-resistant rubber (or polyurethane material) outer wheel, and the steel wheel can be driven directly by a motor. Two lifting support columns 2 are respectively arranged at the front and rear of the boat body. Before the landing craft is used and when it is sailing underwater, the lifting support columns 2 are in an inwardly contracted state. When it is necessary to transport materials such as tanks, the lifting support columns 2 are extended directly to the ground, fixing the position of the boat body so that it will not move, and at the same time ensuring that the tanks and other cargo can be smoothly climbed to the parking position on the boat. After the cargo is transported, the lifting support columns are retracted, and the boat can move on the ground or inside the mother ship through the steel wheels until it enters the water.

[0019] Example 1, see Figures 1 to 9As shown, the controllable buoyancy multi-purpose transport boat includes a hull 8, and the bottom of the hull 8 is respectively provided with lifting support columns 2, the bottom of the hull 8 is provided with load-bearing wheels 3 and steering wheels 1, and two propeller pillars 6 that can be retracted downwards are symmetrically provided on both sides of the hull 8, and the bottom of the propeller pillars 6 is provided with lifting propellers 4, and thrusters 9 are respectively installed on both sides of the tail of the hull 8 in a liftable manner; more specifically, thruster telescopic columns 7 are respectively provided on both sides of the tail of the hull 8, and the thruster 9 is installed at the bottom of the thruster telescopic columns 7, and the lifting support columns 2 and the thruster telescopic columns 7 are both hydraulic telescopic columns; the thruster 9 is an umbrella-shaped thruster including a thruster housing 91, a motor 92, an eccentric thruster, and a thruster housing 91. The motor 92 is arranged in the propeller housing 91, and the eccentric disk is installed on the rotating shaft of the motor 92, and the eccentric disk is provided with an eccentric shaft 93. One end of the crank 94 is connected to the eccentric shaft 93, and the other end is connected to one end of the connecting rod 95. The other end of the connecting rod 95 is connected to an umbrella rib ring 100 slidably installed on the fixed sliding rod 97. The fixed sliding rod 97 and the fixed ring 96 are both installed at the rear end of the housing 91. The umbrella rib ring 100 is provided with an umbrella frame 98, and the umbrella frame 98 is provided with an umbrella surface 99. The fixed sliding rod 97 is provided with a limit ring 101. When the propeller 9 is working, the motor 92 drives the eccentric disk and the eccentric shaft 93 to rotate, the eccentric shaft 93 drives the crank 94 and the connecting rod 95 to move, and the connecting rod 95 drives the umbrella rib ring 100 to reciprocate on the fixed slide rod 97, thereby driving the expansion and folding of the umbrella frame 98, thereby driving the expansion and folding of the umbrella surface 99. When the umbrella surface is expanded backward, the umbrella surface will be subjected to a forward reaction force, thereby pushing the transport boat forward. This principle is similar to the water jet propulsion method of jellyfish. The two propellers 9 of the present invention can work synchronously or alternately. This flexible working mode enables the two propellers 9 to be used in a variety of application fields. The advantages of this propulsion method are: high propulsion efficiency, further noise reduction, no cavitation phenomenon caused by the rotation of the propeller propeller; no fixed and easily recognizable noise generated by the single rotation of the propeller propeller. The noise it produces during propulsion is more like the sound made by marine life swimming, which is more confusing; and the motor 92 is encapsulated in the propeller housing 91, close to the water surface, and the heat and infrared radiation it generates are effectively absorbed and isolated by the housing and the water body, thereby greatly reducing the exposure of infrared characteristics; adjusting the angle of the propeller can control the direction of travel.

[0020] In this embodiment, track grooves 81 are provided on both sides of the upper surface of the hull 8, and track sliders 82 are slidably provided in the track grooves 81. The back of the track sliders 82 is provided with protrusions 821 matching the track grooves 81. By providing the track sliders 82, different objects can be easily transported, such as Fig.10As shown, it is easy to quickly change into different equipment (such as adding torpedoes, mines, and aircraft guns) and transform into an unmanned submarine, which can attack enemy ships from underwater; or it can carry mines and secretly lay underwater minefields to block enemy waterways or ports; or it can be equipped with aircraft guns to become a firepower platform on the beach to carry out strikes and fire suppression.

[0021] In this embodiment, hidden locks 13 are provided in opposite directions at both ends of the hull 8 near the track groove 81, and the track slider 82 is provided with a locking groove 822 that cooperates with the hidden lock 13. In this way, when the track slider 82 moves into place along the track groove 81, the hidden lock 13 can be accurately aligned with the locking groove 822 on the track slider and inserted therein, thereby realizing the locking function. The cooperation between the hidden lock and the locking groove can effectively improve the safety and stability of the system and prevent it from moving or escaping from the track groove 81.

[0022] like Figure 8 As shown, the concealed lock 13 includes a lock shell 131, a lock tongue 132, a fixing column 133 and a spring 134. The lock shell 131 includes a first cavity 1311 and a second cavity 1312 which are separated by a partition to accommodate the lock tongue 132. Two fixing columns 133 are provided at the end of the lock tongue 132 away from the locking. The spring 134 is sleeved on the two fixing columns 133 and is arranged in the first cavity 1311. The two ends of the spring 134 are respectively abutted against the lock tongue 132 and the partition; the two fixing columns 133 pass through one end of the second cavity 1312 and are connected by a connecting block 135. The connecting block 135 is provided with an unlocking column 136. The upper surface of the second cavity 1312 is provided with a sliding hole 13121 which cooperates with the unlocking column 136.

[0023] like Figure 8 and Fig. 9 As shown, the concealed lock 13 also includes an unlocking rod 137, which is connected to the unlocking column 136. One end of the unlocking rod 137 is rotatably mounted on the hull 8, and the other end is an operating end. When unlocking, by pressing the operating end, the unlocking column 136 can be driven to slide in the sliding hole 13121 using the lever principle, thereby driving the lock tongue 132 to contract and compress the spring.

[0024] In this embodiment, the head of the track slider 82 is arc-shaped, and the tail is dovetail-shaped.

[0025] In this embodiment, a weighing sensor, a controller 10 and a processor are provided on the hull 8. The weighing sensor is used to sense the weight of the object and transmit the weight signal to the processor. After processing the weight signal, the processor generates a corresponding control signal and transmits the control signal to the controller. The controller adjusts the rotation speed of the lift propeller 4 according to the received control signal; for example, if the weight of the object exceeds a preset threshold, the controller will increase the rotation speed of the lift propeller 4 to enhance the lift of the hull; conversely, if the weight of the object is lighter, the controller can reduce the rotation speed of the lift propeller 4 to save energy or maintain the stability of the hull.

[0026] In this embodiment, a camera 11 is provided on the propeller strut 6. The camera 11 is convenient for the operator to observe the outside situation and can be used for tasks such as monitoring, reconnaissance or photography, so as to facilitate the operator to observe the outside situation.

[0027] In this embodiment, the cross-section of the propeller strut 6 is in the shape of a water drop, which can reduce the resistance of underwater navigation and improve the efficiency and performance of the system.

[0028] In this embodiment, the umbrella cover 99 is made of Dyneema material, which is light, strong and durable, suitable for extreme environments, has high strength (15 times stronger than steel, but lighter), is soft and resistant to repeated folding, is not easy to break, has good waterproof performance, does not absorb water, and has good wear resistance.

[0029] The transport boat of the present invention uses other ships as its mother ship, and the mother ship provides it with electric drive through the wire 12. It is usually stored on the mother ship for standby, occupying less space. The wire transmission method must ensure a transmission distance of more than 40km. Due to the influence of the curvature of the earth, the detection distance of the enemy radar on the sea surface generally does not exceed 40km. In this way, our transport boat can achieve over-the-horizon transportation outside this distance, which is relatively concealed and safe, especially when diving underwater.

[0030] When the lift provided by the lift propeller 4 of the present invention is large enough, the hull can be lifted out of the water, thereby eliminating the wave-making resistance and having a very good wind and wave resistance effect, making the driving more stable and safe, and the seaworthiness is very good; and because the propeller 9 at the rear is hidden underwater, the transport boat can sail at high speed, and the waves and wake generated on the water surface are also very small; and the power is driven by electric motors, which has very little noise, and does not produce exhaust gas, smoke and other adverse factors that may expose the trace, making its movement more concealed.

[0031] The present invention can maintain free suspension at any depth and realize underwater diving. Of course, after loading objects, necessary sealing must be done before diving underwater. If carrying people, a cockpit and oxygen cylinders for underwater breathing must be equipped.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
