Description

   Spraying structure and spraying method of water vapor jet boat   

The invention relates to a ship using water vapor as a power source. Supply air in front of the high-pitch propeller to eliminate cavitation; then use high-pressure compressed air to spray the high-pitch propeller water jet to generate high-speed jet water flow with air; and use the horn sleeve to increase the propeller water flow velocity and more Can extend the stress time. In the law of propellers, the ship ’s speed increases, and the host needs cubic multiples of horsepower. However, when the drainage speed is increased, the squared kinetic energy is generated. The horsepower required by the propeller is reduced to become squared horsepower. It is not a cubic multiple, so it is fuel-efficient. Structural systems and spraying methods for operating ships.

Historically, when ships use propellers or water-jet propellers, they have avoided the cavitation phenomenon in particular to avoid the water flow in front of the propellers, which is too late to supply the propellers. When the water pressure reduces the supersaturated steam pressure, it will cause water to be evaporated into gas. Once this gas bursts, a water hammer action will occur, producing a 49mPa impact force, which will seriously damage the propeller blades. Because E = MC ² , under the limitation of the pumping and draining speed C ² , only the propeller is increased in diameter, and the main engine speed is reduced, and the increase of M (mass) is in the end. Therefore, the speed C is not increased, and the effect is not good.

When the applicant Mr. Lu Zhengzhong picked up the new ship “Asia Breeze Wheel”, the ship suffered a typhoon, and afterwards it was docked for inspection. All the steel plates on the water surface were completely ribbed. For this reason, it was later found from the experimental data of the ship model and the observation of the formula that the water was carried by the storm and hit the hull at high speed, and the kinetic energy was the square of the speed, so that the kinetic energy would hit the concave hull; The hull below the waterline is purely impacted by waves. At normal speeds, there is not so much force to deform the hull. Therefore, the compressed air is sprayed on the propeller water flow, and it is carried into high-speed power. Compared with the general use of only low-speed water flow as the power, the fuel consumption rate of this spray compressed air added to the propeller water flow is only general. The fuel consumption rate of the ship is 1/2; 1/3; 1/4; 1/5 ... or less, which decreases as the flow rate increases.

Therefore, how to invent a water-air jet boat structure, change the traditional power application method of the ship, so that the ship can no longer lift the displacement of the propeller, use the horn sleeve to reduce the diameter of the outlet to increase the speed of the water flow; The high-speed water flow of the pitch propeller, and the ultra-high speed impacts out, increasing the water flow speed again to obtain greater kinetic energy. This is similar to the propeller aircraft, entering the era of jet aircraft, the obvious huge effect of increasing the fluid discharge velocity. What's more, because water has incompressible properties, it can easily increase the flow rate and obtain the power that can even become a water jet! The velocity of the air taken is 3000 times that of the liquid, and the interaction is beneficial, which is the positive disclosure of the present invention.

The purpose of the present invention is to provide a water-air mixed jet power ship, which mainly uses the water flow that supplies compressed air to impact the high-pitch propeller or high-jet water propeller; the water flow is washed out by the compressed air belt at high speed, and the horn is added In addition to increasing the water flow velocity, the sleeve also prolongs the reaction time and improves the ship's kinetic energy, saving energy and high-speed and safe navigation. The invention is a water-jet gas-powered ship. It supplies air before the high-pitch propeller to eliminate cavitation; it supplies compressed air next to / after the propeller and gets square-speed kinetic energy due to E = MC ² high-speed belt drainage. Structural system for propelling ships, and method of operation, including: a set of various compressed air piping systems, a single or multiple propellers (or high pitch or tandem propellers), or water jet thrusters, a single or multiple nozzles The horn sleeve, in parallel or in series, uses high-speed backward thrust to impinge on the water flow, spraying out the water or the water surface at the back (when it does not affect other things), to provide power to the ship.

In order to achieve the above object, the present invention provides a spray structure of a water vapor jet boat, which is applied to the high-speed sailing hull and is mainly arranged around the propeller; supplies air in front of the propeller to eliminate cavitation; uses a horn sleeve to reduce the propeller outlet Diameter to increase the flow rate; and then use compressed air of various pressures to impinge on the propeller water flow once or several times to extend the reaction time and obtain the maximum kinetic energy. The main spray structure of the water-jet jet boat includes: at least one set of compressed air pipeline system, and a horn sleeve. A compressed air piping system is provided around the propeller. The compressed air piping system includes: a pressure detection pipe meter, a plurality of low pressure compressed air pipes, and a plurality of high pressure compressed air pipes. The pressure detection pipe meter is arranged on the front side or rear of the propeller. On the side, a plurality of low-pressure compressed air pipes and a plurality of high-pressure compressed air pipes are respectively arranged at appropriate positions around the propeller, and each of the low-pressure compressed air pipe and the high-pressure compressed air pipe has a nozzle; the horn sleeve is sleeved on the compressed air pipe. System front so that it is at the front of the propeller.

In a preferred embodiment, it includes one or more sets of high-pressure water pumps and compressed air systems connected to water vapor ejectors, and the nozzles are arranged inside and outside the high-speed sailing ship for powerfully controlling the operation of the ship.

The following is a description of specific embodiments of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

The following describes the embodiments of the present invention with reference to the drawings. It should be noted that the following drawings are simplified schematic diagrams, and only the basic concepts of the present invention are illustrated in a schematic manner. Only the structures related to the present invention are illustrated in the drawings. Rather than drawing according to the number, shape and size of components during actual implementation, the type, quantity and ratio of each component during actual implementation are not limited to the illustrations, and can be changed according to the actual design needs.

First, please refer to FIG. 1, FIG. 2 and FIG. 3, which are schematic side-view structural diagrams of the embodiment of the conventional ship in order to “improve” the water-gas jet-powered ship of the present invention. As shown in the figure: the spray structure 1 of the water-gas jet boat of the present invention is applied to the high-speed sailing hull, and is arranged around the propeller 2 to supply air in front of the propeller 2 to eliminate cavitation, using compressed air of various pressures, once Or several times the jet impinges on the water flow of the propeller 2 to extend the reaction time of the reaction force. The jet structure 1 of the water-air jet boat includes at least one set of compressed air pipeline system 11 and a horn sleeve 12. The compressed air piping system 11 is arranged around the propeller 2. The compressed air piping system 11 further includes a pressure detection pipe meter 111, a plurality of low-pressure compressed air pipes 112, and a plurality of high-pressure compressed air pipes 113. The pressure detection pipe meter 111 automatically detects the pressure in front of the propeller, and the air supply pressure regulating valve automatically increases the pressure detected by 0.1kgs / cm ^{2 to} supply air in front of the propeller 2. The low-pressure compressed air pipe 112 is reserved for use after the vehicle is used. From "at half speed in Hong Kong", when receiving the clock at "full speed in Hong Kong", the solenoid valve is opened to supply 1 ~ 6kgs / cm2 of gas to the low-pressure air pipe 112; When the clock is “full speed”, the air is supplied to 25 ~ 30kgs / cm ² to the high-pressure air pipe 113. Because the hull structure has not been strengthened, although high-speed and fuel-efficient navigation, the time and speed of the vehicle must not be exceeded, otherwise the accident will definitely occur.

Please refer to FIG. 4 again, which is a schematic structural view of a side view of a preferred embodiment of a water-gas jet boat according to the present invention. The structure of a high-speed ship with a high safety factor structure and a water-jet propeller are redesigned and manufactured, as shown in the figure. Propeller 2 uses a high-pitch small-diameter propeller. Due to the high-speed jet of mixed water and gas, if it gets more than 10 times the water flow speed, it will get more than a hundred times the kinetic energy, which can reduce the diameter of the propeller. The pressure in front of the propeller 2 and the air supply pressure regulating valve automatically increase the detection pressure of 0.1kgs / cm2, and the air is supplied in front of the propeller 2, and the low-pressure compressed air pipe 112; After the vehicle is prepared: When the vehicle is used, "at half speed in Hong Kong" When receiving the "full speed in Hong Kong" clock, the solenoid valve is opened to supply 1 ~ 6kgs / cm2 to the low-pressure air line 112; when using the car, "full speed in Hong Kong", when receiving the "full speed at sea" clock The air supply is 25 ~ 30kgs / cm2 to the high-pressure air pipe 113. The nozzle diffuses the air jet, mixes as much as possible to promote the speed of the water flow, and the horn sleeve 12 is extended to increase the time for receiving more backward reaction force.

Please refer to FIG. 5 again, which is a schematic structural view of a side view of another preferred embodiment of the water and gas jet boat according to the present invention. The structural diagram of a high-speed ship is redesigned and manufactured. As shown in the figure, the pressure detection pipe meter 111 automatically detects The pressure in front of the propeller 2 and the air supply pressure regulating valve automatically increase the detection pressure of 0.1kgs / cm2, and the air is supplied in front of the propeller 2, and the low-pressure compressed air pipe 112; after the vehicle is prepared: use the vehicle from "at half speed in Hong Kong", close When the clock is “full speed in Hong Kong”, the solenoid valve is opened, and the air supply is 1 ~ 6kgs / cm2 to the low-pressure air line 112. When the car receives “full speed at sea” clock from the “full speed in Hong Kong”, the gas supply is 25 ~ 30kgs / cm2 to high-pressure air line 13. The nozzle diffuses the air, mixes and pushes the speed of the water flow, and the horn sleeve 12 is extended to obtain more pushback reaction force.

Please refer to FIG. 6 again, which is a schematic structural diagram of an embodiment of the “nozzle” of the water-gas mixed jet of the present invention, as shown in the “vacuum pumping principle”. Generally, the high-pressure water flow increases in speed after depressurization, and a low-pressure region is generated next to it; If it is shown in Fig. 6, in the low pressure area, high pressure compressed air is injected to spray out, and after the water flow is atomized, the water flow speed is mixed and the horn sleeve 12 is extended to extend the reaction force receiving time; In order to withstand more pushback reaction force, if the water column is not rushed out, you will get more kinetic energy. Commercially available "Mingchuang", the domestic pumpless spray gun, the pressure at the outlet of the spray gun can be as high as 90Kgs / cm2, which is the principle, it will connect 1Kgs / Cm2 and 10mm domestic water pipes to 3mm nozzles, and then connect the air Pipe to eliminate the viscosity coefficient of water flow, without the use of pumps, the performance of pressurizing nearly 90 times, can prove the high-pressure high-speed water flow, the excellent method of obtaining and the results of specific performance facts. Thirty years ago we used it on board!

Please refer to FIG. 7 again, which is a flowchart of a spraying method for a water vapor jet boat according to the present invention. As shown in the figure, it includes the following steps:

In step 301, at least one set of compressed air pipeline system for supplying various pressures is provided in front of a propeller of a high-speed sailing hull to provide compressed air.

Step 303: The compressed air is impinged on the high-pressure water flow one or more times with a nozzle, so that the high-pressure water flow is diffused or atomized.

In step 305, the water-gas mixed flow is passed through the horn sleeve to have a higher flow rate and a longer time to rush out, thereby greatly improving the kinetic energy.

In step 307, another high-pressure water pump is used, which operates on the same principle, and strongly controls the operation of the hull to allow the hull to surface, reduce the draft area, and keep the hull balanced and upright without shaking.

It can be known from the above-mentioned injection method that when the prepared vehicle of the present invention is half speed to full speed, the compressed air is supplied to the front of the propeller or water jet propeller. At low speed, a large power state is required, and the power can be immediately provided to make the main engine accelerate easily; secondly At the moment when the prepared vehicle reaches full speed at sea, the high-pressure compressed air is turned on, the pressure is gradually increased, and the high-pressure gas is ejected, so that the host can easily get great power, the propeller thrust is greatly increased, and the hull is quickly and easily accelerated and decelerated; under this condition, The hull is not modified, except that a compressed air machine and its control system are added to the vicinity of the propeller or waterjet to give the hull extra extra power, so care must be taken not to overload the vehicle, which exceeds the hull design speed. There are also huge impacts caused by vehicles used in river crossings and gates, which must be used slowly; and when sailing at full speed, vehicles must be slowly added or subtracted to avoid impact forces. In a typhoon, you must reduce your car and sail carefully, because the stress on the hull is unusually huge.

Compared with the conventional technology, the spray structure and spray method of the water-air jet boat of the present invention mainly adopts the supply of compressed air to impinge the high-pitch propeller water flow, or the water flow of the high-jet propeller; the compressed air is carried out at high speed. Coupled with the horn sleeve, the outlet diameter is reduced, the water flow speed is increased, and the reaction time is extended to obtain huge kinetic energy, which is used for energy-saving and high-speed navigation. Second, supply air in front of the high-flow pump to eliminate cavitation, supply compressed air to the horn sleeve nozzle, apply it to the inside and outside of the ship, impact high-speed water flow, obtain huge kinetic energy to control the operation of the ship, and improve the safety of navigation; Powerful control capabilities, similar to modern jets, can have cobras, and move like fallen leaves, and fly at supersonic speed in an instant. Ships can be controlled in this way to be safe. There is no fear of typhoons, no escort, and no host. The generator can be used alternately.
