Description

Technical Field

[0001] The present invention relates to the field of ship machinery, and particularly to a power device and a pressurized water ship having the device. Background Art

[0002] In a general ship, high-temperature and high-pressure air in a cylinder does work on a piston, and then through a complex mechanical structure, the force is transmitted to a paddle blade, and the water is pushed backward by the paddle, so that the hull obtains a forward reaction force.

[0003] Currently, according to the types of propellers, most ships are paddle steamers, water jet boats, and propeller ships. In order to prevent the paddle blades from pressing down and lifting the water when entering and leaving the water, the paddle wheels of paddle steamers can only be lifted. For huge paddle wheels, the working part is very small, and the use effect is not good. A water jet boat is equipped with an internal water pump. Compared with a propeller ship, only pipes are added inside the ship, and adding pipes will increase the frictional force between the water and the ship. Experiments have also proved that the use effect is not good, but it has the advantage that the propeller is not easily damaged when the ship sails in shallow water.

[0004] Compared with paddle steamers and water jet boats, the propeller ship has the best use effect. However, when the propeller blades do work, in addition to pushing the water backward, there is also a rotational torque that pushes the water to rotate. This force is actually wasted and does not help the ship move forward. Summary of the Invention

[0042] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0043] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0044] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0045] In the description of the present invention, unless otherwise clearly defined and limited, the terms "installation", "connection", "connection", "fixation" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0046] The present invention discloses a power device and a pressure water ship equipped with the device, as Figures 1 - 3 shown. The power device is mainly composed of a water pump 6, a pressurized water tank 5, a pressure water cylinder 2, a high-pressure water tank 1, a combustion chamber 13, a water flow meter 4, a turbine engine, a fuel pump, an air pump, etc. Among them, the water pump, the fuel pump and the air pump belong to auxiliary external machines, and their power can be flexibly configured.

[0047] The water inlet 7 of the pipeline is located at the front end of the ship. The pipeline is connected to the water pump 6. Then the water in the pipeline is introduced into the pressurized water tank 5 by the water pump. A second one-way valve 9 is arranged at the cylinder water inlet between the pressurized water tank 5 and the pressure water cylinder 2. Water can flow from the pressurized water tank 5 into the pressure water cylinder through the second one-way valve, but cannot flow back in the reverse direction. A first one-way valve 8 is arranged at the cylinder water outlet between the pressure water cylinder 2 and the high-pressure water tank 1. Water can flow from the pressure water cylinder into the high-pressure water tank, but cannot flow back in the reverse direction. The high-pressure water tank 1 is connected to the water spray pipe 7 to spray out water and provide forward power for the hull.

[0048] A filter screen is arranged at the water inlet to filter debris in the water. The water inlet surface is inclined to prevent debris from accumulating in front of the screen. There is some air stored in the pressurized water tank, which can play an elastic role. A water flow meter 4 is installed between the pressurized water tank and the pressure water cylinder, which can allow people to monitor the working state of the cylinder at any time.

[0049] The internal space of the pressure water cylinder 2 is generally cylindrical. When working, the upper part is gas and the lower part is water. In order to prevent the water surface from being uneven when the ship shakes and affecting the working effect, a boundary plate 25 covering the water surface needs to be set. The outer shape of the boundary plate matches the inner wall of the pressure water cylinder. The material density is less than that of water, so it floats on the water surface. A central guide post 11 passes through the center position of the boundary plate. Both ends of the central post are fixed on the cylinder body. There is also a side guide post 10 passing through the edge position of the boundary plate, and both ends are fixed on the cylinder body. The central guide post and the side guide post are perpendicular to the boundary plate surface. The boundary plate is connected with a first sliding sleeve 24 and a second sliding sleeve 20, and the two sliding sleeves slide along the guide posts. The boundary plate can rise and fall with the water surface, and the sleeve is fixedly connected with the boundary plate. The central guide post prevents the boundary plate from shaking, and the side guide post prevents the boundary plate from rotating.

[0050] There is a combustion chamber 13 above the pressure water cylinder 2. There is a raised small space at the middle column inside the cylinder. A first on-off valve is arranged between the small space and the combustion chamber. There are a fuel spray head and an air spray head in the combustion chamber. The fuel spray head is connected to an oil pump, and the air spray head is connected to an air pump. They continuously spray fuel and air into the chamber. There is also an ignition device in the combustion chamber. Once ignited, the combustion chamber can keep burning continuously. The amount of air sprayed into the combustion chamber is greater than the amount of fuel. There is also a fuel spray port at the upper end of the pressure water cylinder. When the burning flame enters the pressure water cylinder through the valve, the cylinder body spray port also sprays fuel at the same time to increase combustion.

[0051] There are guide grooves on both sides of the rectangular valve openings of the combustion chamber and the pressure water cylinder. The rectangular first valve plate can slide up and down in the guide grooves. The lower side of the first valve plate is connected to a first rack, and the first rack is externally engaged with a gear. The gear is rotatably installed inside the pressure water cylinder and can pull the first valve plate up or down. The gear shaft passes through both sides of the cylinder and is connected to a fuel valve on one side to control the fuel sprayed into the cylinder. A second rack is provided outside the first sliding sleeve. When the boundary plate rises to a certain point, the second rack meshes with the gear and drives it. When the boundary plate rises, it can drive the gear to rotate, thereby driving the first valve plate to descend. When the boundary plate descends, it can also drive the first valve plate to rise. After the boundary plate descends to a certain point, the second rack disengages from the gear and no longer affects the first valve plate.

[0052] In the middle upper part of the first valve plate, there is an oval first flap 21. The rotating shaft of the first flap is located below the upper and lower center lines of the first flap. The areas on both sides of the shaft are different. The area above the flap shaft is larger, and the area below is smaller. During use, when the interface plate rises, the first valve plate is pulled downward by the gear. The first flap does not move when it reaches the valve opening. It still does not move when the shaft of the first flap is exposed at the valve opening. When the area of the shaft exposed on the first flap at the valve opening is larger than the area below the shaft, due to air pressure, the first flap rotates clockwise and the valve opening opens. When the valve plate moves upward, the first flap automatically closes slowly.

[0053] Above one side of the side guide post of the pressure water cylinder, there is a raised small space, and two exhaust valves are arranged side by side here, one is an automatic exhaust valve and the other is a manual exhaust valve.

[0054] A hook is installed on the second sliding sleeve. The hook is a horizontal nail, which controls the automatic opening and closing of the valve. There are sliding grooves on both sides at the valve opening, and a rectangular second valve plate can slide up and down in the middle. There is a rectangular card slot on the lower side of the valve plate. The horizontal nail can move up and down in the card slot and can also drive the second valve plate up and down. The valve opening is oval, and an oval second flap 18 is rotatably installed in the valve opening. The shaft of the second flap is biased upward, and the area above the flap on the shaft is smaller than the area below. During use, when the second valve plate moves downward, the second flap is slowly exposed. Since the area above is small, the air pressure inside cannot push the flap, and the gas cannot be discharged. When the valve plate continues to slide down, when the area below the flap shaft is larger than the area above, the second flap flips clockwise, and a large amount of gas can be immediately discharged.

[0055] To enhance the sealing performance and prevent leakage, stepped sealing parts are provided between the first flap and the second flap and the corresponding valve openings, as Figure 2 shown.

[0056] The high-pressure water tank 1 is generally cylindrical, with spherical upper and lower sides. The water inlet and outlet of the high-pressure water tank are both at the lower part. There is also some air in the tank. When water enters and exits, the air plays an elastic role, making the pressure in the water tank more stable.

[0057] To make the pressure in the water tank more stable, multiple water-pressing cylinders need to be set up. One pressurized water chamber, one combustion chamber, one exhaust pipe, one high-pressure water tank, multiple water-pressing cylinders, and multiple water spray nozzles.

[0058] As Figure 10 shown, each water-pressing cylinder is connected to an exhaust branch pipe 29. A turbine engine 28 is added in the main exhaust pipe 26 to provide energy for the ship. Outside the turbine engine, a pressure relief port 27 of the pressurized water chamber is added. The water and exhaust gas are discharged together to provide some forward power for the ship and can also ensure the stability of the pressure in the pressurized water chamber.

[0059] To prevent the high-pressure exhaust gas of one water-pressing cylinder from flowing back into other cylinders, the opening of the exhaust branch pipe should directly face the turbine. When the turbine rotates, gas backflow will not occur.

[0060] When starting to work, start the oil pump, air pump, and water pump, and ignite in the combustion chamber. When the exhaust port of the water-pressing cylinder 2 just opens, the second one-way valve 9 opens, and the pressurized water enters the water-pressing cylinder, and the water-pressing cylinder can work normally. When the exhaust port is closed, the water-pressing cylinder cannot work, and the water flow meter does not move. The manual exhaust port needs to be opened to observe the water flow meter. If the water flow meter moves, it means that water is entering and exhausting. When the water flow meter stops, close the manual exhaust valve, and the cylinder starts to work normally.

[0061] During operation, the pressurized water enters the water-pressing cylinder, and the partition plate rises. When it rises to point B, as Figure 4 shown, the exhaust valve closes. Subsequently, the partition plate rises to point A, as Figure 5 shown, the first flap 21 opens, and a large amount of burning air suddenly enters the cylinder. The fuel nozzle sprays fuel, the air pressure on the partition plate increases, the partition plate descends, the second one-way valve 9 at the water inlet automatically closes, and the first one-way valve 8 at the water outlet automatically opens, and the water flows to the high-pressure tank 1. As the water level drops, the partition plate drives the first sliding sleeve 24 to descend, which in turn drives the gear 23 to rotate. At the same time, the gear drives the first rack to rise, and the first on-off valve slowly closes. When the partition plate descends to point B, as Figure 6 shown, the second one-way valve 9 at the water inlet is always in the closed state, and the first one-way valve 8 at the water outlet is always in the open state. When the partition plate descends to point C, as Figure 7 shown, the second rack disengages from the gear, and the partition plate no longer affects the first valve plate. At this time, the first flap is completely closed, the water inlet is always in the closed state, and the water outlet is always in the open state. When the partition plate descends to point E, as Figure 8As shown, the horizontal nail hooks the bottom end of the card slot of the second valve plate and is pulled down. When the partition plate reaches point F, as Figure 9 shown, the second flap 18 suddenly opens, and a large amount of exhaust gas suddenly discharges. The air pressure above the partition plate decreases, the first one-way valve 8 at the water outlet automatically closes, and the second one-way valve 9 at the water inlet automatically opens. The pressurized water enters the pressure water cylinder again, the partition plate rises, and the horizontal nail rises in the card slot of the exhaust valve plate while the exhaust valve plate remains stationary. When the partition plate rises to point D, as Figure 10 shown, the horizontal nail begins to push the second valve plate upward. When the partition plate rises to point C, as Figure 11 shown, the second rack contacts and begins to engage with the gear. When the partition plate reaches point B, the exhaust valve closes, and then the first flap 21 opens, entering the next working process.

[0062] When the partition plate descends, both the first on-off valve and the second on-off valve are closed. Since the second valve plate is provided with a rectangular card slot, the horizontal nail initially slides downward from the card slot but does not pull the second valve plate. When it reaches point E, it pulls the second valve plate. When it reaches point F, the second flap rotates and the second on-off valve opens to discharge the exhaust gas. When the partition plate rises, the horizontal nail slides upward in the card slot without pushing the second valve plate, so the second flap remains open until point B when the second flap closes, the exhaust valve closes, and the intake valve then opens. When the partition plate descends, the exhaust valve remains closed until the bottom when the exhaust valve opens. When the partition plate rises, the exhaust valve remains open. Since the exhaust valve remains open when the partition plate rises and remains closed when the partition plate descends, when the machine stops, it is unknown whether the exhaust valve is open or closed. If it is open, the pressurized water can enter the cylinder and the machine can operate normally. If it is closed, there is a sealed space above the partition plate, and the pressurized water cannot enter the cylinder, so the machine cannot work properly. Therefore, the manual exhaust valve needs to be opened. After the manual exhaust valve is opened, the pressurized water flows into the cylinder, the gas is discharged from the manual valve, the partition plate rises to the top, the water flow meter stops, and at the same time the intake valve opens. If the manual valve is not closed, the gas will enter the cylinder from the combustion chamber and be discharged from the manual valve again. Close the manual valve, the high-pressure gas presses the partition plate, and the water under the partition plate is pressed into the high-pressure water tank. Then it works normally.

[0063] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
