The sailing boat needs a huge sail to drive due to too small energy density of wind energy, is greatly influenced by wind force, and cannot actively and quickly drive. Therefore, sailing boats cannot meet the requirements of modern marine transportation and can only be used in a very small amount for sports or tourism.

Advantageous effects

Compared with the prior art, the semi-submersible ship for sea energy driving and power generation has the advantages that:

1. the high-pressure water is mainly generated by the ocean current sea wave energy collector and the water pumping and pressurizing device, the energy of the ocean current sea waves is fully utilized to generate the high-pressure water, the use of other energy sources is not needed or reduced, and the energy-saving effect is good. Wherein, the dynamic duckweed can fluctuate up and down along with the sea waves to generate power and drive the first piston cylinder structure to extract seawater and pressurize; and the ocean current in the horizontal flow direction can drive the ocean current driving wheel submerged below the sea surface to rotate and drive the membrane-blowing box to pump seawater and pressurize the seawater. The pressurized seawater can be respectively supplied to the high-pressure jet flow spray head and the hydraulic power generation system according to the requirement. Because the ocean current and ocean wave energy is huge, especially under the condition of strong wind and strong waves, a large amount of energy can be collected by the ocean current and ocean wave energy collector to be used as the driving energy and the power generation of the semi-submersible ship, basically no fuel is needed, and no fuel supply is needed on the sea, so that the single sailing time can be greatly prolonged, the semi-submersible ship can be favorable for carrying out long-term operation on the sea, the special requirements of island power supply, sea surface operation power supply, sea foundation construction and the like with great difficulty are met, and the development and utilization of the sea and the island are easier and more efficient.

2. Because the ship is pushed to advance by the reaction force of the high-pressure water sprayed by the high-pressure jet nozzle, when the high-pressure jet collides with the seawater, the noise generated by the high-pressure jet nozzle is greatly reduced compared with the collision between the liquid and the propeller. In addition, because the main water suction port is positioned at the front part of the ship and the high-pressure jet flow spray head is positioned at the rear part of the ship, the water suction at the bow reduces the water level at the bow, the water spray at the stern raises the water level at the stern to form a so-called downhill effect, the effect is offset with the uphill effect formed by the ship body propelled in water, the water resistance projection area is reduced, the bump of the ship is reduced, and therefore the ship can run smoothly and save energy.

3. The high-pressure jet nozzle is adopted to solve the problem that seawater enters the engine room along the transmission shaft in the traditional propeller propulsion system.

4. Can drive the swing of high-pressure jet nozzle through steering mechanism, realize turning to of boats and ships, need cooperate the rudder just can turn to for traditional screw, adopt rotatable high-pressure jet nozzle to need not additionally to use the rudder again.

5. When the sea surface is calm and the energy collected by the ocean current and ocean wave energy collector is insufficient to drive the ship, the motor can drive the large-stroke reciprocating pump to pump seawater to pressurize and convey the seawater to the high-pressure jet flow nozzle, so that the ship can sail with enough power under all conditions. As the auxiliary power which is started under special conditions, the active power system is smaller and more convenient to arrange.

Because the positioning sliding pin 33 always moves around the outer side wall of the guide plate 62, the gear 4 is always engaged with the meshing rack 32 which is annularly arranged on the transmission rack sliding block 3, the transmission rack sliding block 3 can move up and down in a reciprocating manner to a large extent, and the piston connecting rod structure 2 is driven to move up and down. In the process, when the gear 4 passes through the arc transition rack 322 of the meshing rack 32, the transmission rack slider 3 can also transversely move relative to the piston connecting rod structure 2, so that the gear 4 is switched between the two linear meshing racks 321, and the aim of up-and-down movement of the piston connecting rod structure 2 can be achieved without reversing and rotating the gear 4. In the process that the piston connecting rod structure 2 moves up and down, when the piston connecting rod structure 2 moves up, negative pressure is generated in the second cylinder body 1, seawater is sucked into the second cylinder body 1 by the water suction port 7, and at the moment, the second one-way valve 81 is closed; when the piston connecting rod structure 2 moves downwards, the water pressure in the second cylinder body 1 is increased, the first one-way valve 71 is closed, the second one-way valve 81 is opened, the high-pressure seawater in the second cylinder body 1 is conveyed to the high-pressure pipe 25 of the high-pressure jet flow driving system of the ship 22 from the high-pressure water outlet 8, the high-pressure jet flow nozzle 24 at the tail end of the high-pressure pipe 25 sprays water to the back of the ship body, and the ship 22 is driven to advance by the reverse thrust of the water.

When the rated high-pressure water pressure of the jet flow driving system is 10MPa, and the tail nozzle of the high-pressure jet flow nozzle 24 is D50, the following can be calculated: the tail jet speed is 100M/s, the maximum thrust is 1.96T, and the maximum water jet quantity is 0.196M³/s。

When the rated high-pressure water pressure of the jet flow driving system is 12MPa, and the tail nozzle of the high-pressure jet flow nozzle 24 is D100, the following can be calculated: the tail jet speed is 120M/s, the maximum thrust is 9.4T, and the maximum water jet quantity is 0.94M³/s。

Generally, the rated pressure of high-pressure water is about 10MPa, and the main power is high-pressure water generated by the sea wave energy collector. The high-pressure water pipe network system achieves high water pressure, large pipe diameter, low flow velocity and low energy consumption.

The implementation process of two main functions of the sea energy driving and power generation semi-submersible ship is described by taking high-pressure water rated pressure of 10MPa as an example:

(1) the sea wave energy is utilized to realize the power generation function:

when the ship is parked or sailed, the second layer of the ship is completely submerged so as to collect the sea energy, and the high-pressure water generated by the energy collector is used for driving the high-pressure water wheel generator to generate electricity.

The hydraulic generator generally adopts more than 3, when the water pressure is more than 10.1MPa, a hydraulic generator is automatically opened through a self-control electromagnetic valve. When the water pressure is less than 9.9MPa, a hydraulic generator is automatically turned off through the automatic control electromagnetic valve, so that the function of high-quality power generation is realized.

(2) The high-pressure water is utilized to realize the driving function:

the ship moves by adopting a high-pressure water jet driving system, high-pressure water mainly comes from a sea wave energy collector, and only under special conditions, the high-pressure water is started to be actively supplemented by an electricity storage driving large-stroke reciprocating pump. The ship thrust is controlled through controlling the flow control electromagnetic valve, the tail spraying direction is controlled, and the ship course is controlled, so that the ship navigation driving function is realized.

The present invention has been described in connection with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, and is intended to cover various modifications, equivalent combinations, which are made in accordance with the spirit of the present invention.
