Definitions
- the invention relates to ship propulsion technology, in particular to a deployment and installation method and an installation structure of a direct suction jet propulsion device in a waterborne body.
- Analyzing ship navigation resistance and propulsion technology can enhance our understanding of the limitations and deficiencies of current propulsion technology, and help open up useful ideas for solving the problem of ship speed and energy efficiency generally low.
- the front water body is like a water wall blocking the advancement of the ship.
- the ship needs to break through the water wall to move forward.
- the infinite thickness of the water wall means that the ship needs to continuously break through the front water wall to keep moving forward.
- the blocking force of the water wall encountered by the ship sailing forward can be called the frontal navigation resistance of the ship, or the sailing resistance against the water.
- the formation of waves at the bow of the ship is equivalent to pushing up the height of the water wall that needs to be breached in front of the ship, and such waves will develop along the side of the ship to the stern due to wake, which will further increase the sailing resistance of the ship.
- the sailing resistance of the ship caused by the bow wave is called the wave making resistance of the ship.
- the navigation resistance of the ship also includes the stern rudder resistance.
- the resistance on the stern rudder is essentially the same in nature and type as the various resistances experienced by a sailing ship. It only accounts for a small proportion of the total resistance experienced by the ship, but it is still the existence of resistance that should not be ignored.
- the sailing resistance, wave making resistance and viscous pressure resistance constitute the absolute bulk of the ship's sailing resistance.
- the factors that determine the magnitude of the ship's sailing resistance are not only highly related to the design of the ship type, but also closely related to the ship's speed.
- the ship's sailing resistance is a function that is quadratic related to the ship's speed. A small increase in the speed of a ship in a high-speed sailing state can lead to a substantial increase in the resistance of the ship encountered by the ship. The higher the speed, the greater the increase in the resistance of the ship.
- the factors that determine the resistance of a ship's navigation are also closely related to the propulsion mode of the ship using the propulsion device and the deployment mode of the propulsion device on the ship. So it is necessary to learn more about ship propulsion technology.
- the current ship propulsion technology can be roughly divided into three categories from its propulsion principle and promotion and application level: propeller propulsion, water jet propulsion and straight-propeller propulsion (or called straight-wing propulsion, flat-rotating blade propulsion).
- Propeller propulsion technology has a long history and is the most widely used. It is the absolute main propulsion technology of ships.
- Existing propeller propulsion technology is still in continuous development and progress.
- Based on propellers, such as counter-rotating propellers, controllable pitch propellers, ducted propellers, nacelle propellers, slightly driven propellers, tandem propellers, and large diameters have been developed.
- Multiple technologies such as low-speed propellers, and even ship propulsion technologies that combine water jet propulsion and propeller propulsion have emerged.
- the so-called shaftless pump propulsion technology belongs to the emerging propulsion technology, and its essence should also be attributed to the propeller propulsion technology.
- Water jet propulsion includes pump jet propulsion and magnetic fluid propulsion.
- Magnetic fluid propulsion is an emerging technology with a short history of birth. The overall technology is being further improved, and its application range is very limited; the water jet propulsion technology was born very early, but it has been silent for a long time, and it has not developed until the past 20 or 30 years. And it's becoming more prominent.
- Western ship power manufacturing powers are committed to the development of large-scale and modular pump-jet propulsion technology, so that it can be applied to large ships, and water-jet propulsion technology is listed as an important direction for future ship propulsion technology development.
- Straight-propeller propulsion is relatively rare, and is generally used in ships with large load changes and high maneuverability requirements, such as tugboats, ferries, and minesweepers. It has a narrow application range and small impact.
- Propeller propulsion and pump-jet propulsion have one thing in common in terms of installation and deployment: they are all deployed and installed on the stern of the ship, and all cannot be deployed and installed in other locations on the ship.
- the propeller Due to the large radial size of the propeller blades, only the stern of the ship can provide suitable installation space. Further, in order to make full use of the propeller to push the water flow to obtain the maximum thrust, the propeller can only be deployed and installed in the stern of the ship.
- the basic structure of the pump jet propulsion device is a straight pipe connected at both ends of a bent pipe, of which the straight pipe takes on the water intake function and the other straight pipe takes on the water spray function.
- the core component of the pump-the impeller it is deployed and installed in the water spray pipe.
- the pump jet propulsion device can also only choose ships
- the stern is deployed and installed, so it is required that the water inlet of the pump-jet propulsion device and the water nozzle are arranged close to each other.
- the water inlet of the pump-jet propulsion device can only be deployed in the only place for ships. The bottom of the stern of a ship.
- Propeller working water flow movement mode When the propeller is rotating, a negative pressure area is created at the water-facing end of the blade. Under the action of negative pressure, the water flow enters the blade from the water-facing side of the blade, and is discharged from the back water end of the blade to form a propulsion after being energized by the blade. Water flow, the propeller working water flow movement mode belongs to the straight-in and straight-discharge mode. However, because the propeller is deployed and installed on the stern of the ship, the hull structure at a certain distance in front of the propeller blocks the straight path of the water flow of the propeller, which determines that the water flow through the blades can only be maintained from the bottom of the stern and the stern when the propeller is working. The lateral water inflow on both sides is continuously replenished.
- the working water flow movement mode of the pump-jet propulsion device water is fed in from the water inlet pipe, and the impeller of the pump is energized and sprayed out from the water pipe at high speed to form a propelling water flow.
- the working water flow inevitably flows through the elbow part, so the inlet and outlet water flows of the pump-jet propulsion device are not collinear, that is, it does not constitute a straight-in and straight-discharge mode.
- the more vivid name of the pump jet propulsion device is the curved suction jet propulsion device.
- propeller propulsion device Whether it is a propeller propulsion device or a pump-jet propulsion device, their structure or working mechanism can only be limited to the deployment and installation of the stern of the ship.
- the limitation of this deployment device causes the propeller working water flow to be maintained only by the bottom of the stern of the ship and the lateral water inflow on both sides of the stern; for the pump-jet propulsion device, this The limitation of the deployment device leads to the maintenance of the working water flow of the pump jet propulsion can only rely on a single water inflow from the bottom of the stern of the ship.
- Such a water intake mode is not only unfavorable to the improvement of ship speed and energy efficiency, but will cause the ship speed and energy efficiency to decrease, indicating that the ship stern deployment and installation mode of the propulsion device is a defective and backward deployment and installation mode.
- the propulsion device can be imagined as a straight cylindrical device body, and the pipe damage when the water flows in the cylinder body is ignored, that is, it can be set to any length.
- the front port of the straight cylinder is the water inlet, and the back port is the water jet.
- a working water flow energizing device is deployed inside the cylinder. The working water flows from the water inlet and is energized by the internal energizing device, and then sprays out from the water jet at high speed. Form a propelling water flow.
- the water inlet and the spray water of its working water flow are in a straight line, it has the aforementioned so-called straight-in and straight-discharge mode, which can be referred to as a direct-suction spraying device or an axial-flowing spraying device in comparison with the curved suction spraying of a pump-jet propulsion device. .
- one or more axial flow jet propulsion devices are deployed and installed on the bottom of the ship, and the water inlet is deployed and installed on the bow of the bottom of the ship; the water jet is deployed and installed on the stern of the ship.
- Water is a substance. Before the water body in front of the axial flow jet propulsion device is sucked in, the water can be regarded as an object placed at the front end of the water inlet of the axial flow jet propulsion device.
- the direction of the pulling force is the same as that of the ship’s advancing direction, which constitutes a pulling effect on the ship’s advancement. It combines with the propulsion force obtained by the propulsion water jet at the rear end of the axial jet propulsion device to form a combined force for the ship’s advancement.
- the forward power is doubled.
- the pulling force is generated as long as the axial flow jet propulsion device is in the propulsion state, which is a derivative force of the axial flow jet propulsion device working in the propulsion state, and is a force that promotes the ship's navigation without additional energy consumption of the ship. force.
- the axial flow jet propulsion device is in the propulsion state, which is a derivative force of the axial flow jet propulsion device working in the propulsion state, and is a force that promotes the ship's navigation without additional energy consumption of the ship. force.
- propeller propulsion or pump jet propulsion it is a form of ship propulsion that cannot be obtained by propeller propulsion or pump jet propulsion.
- the ship’s bow constitutes a barrier. Part or most of the water body of the water wall is transformed into a working water body that is sucked in by the axial jet thrust device from the water inlet provided at the bow of the ship, and after being energized, it is ejected from the stern of the ship to become a part of the propelling water body and the resistance to sailing against the water.
- the above-mentioned axial jet propulsion device and water-inlet deployment installation mode are also applicable to submarine devices such as submarines (except for some submarine devices that use small and decentralized propeller propulsion devices).
- the difference between submarine devices and ships is: submarine devices Wrapped by water, there is no wave-making phenomenon and wave-making resistance; the water intake mode varies according to the deployment and installation position of the propulsion device.
- the propeller propulsion mode because it is deployed and installed in the stern of the ship, the mode is taken from the bottom of the stern of the ship and the lateral water inflow on both sides of the stern. It can be seen from the force analysis that the propeller propulsion device’s water intake pull force obtained by the lateral water intake on both sides of the stern also exists, but their directions are opposite to each other, and they are perpendicular to the navigation direction of the ship. Contribution; and the propeller propulsion device obtains the water intake pull force from the bottom of the stern, and its direction is also perpendicular to the ship’s navigation direction.
- the direction points to the depth of the water body, which is equivalent to increasing the weight of the ship, resulting in an increase in the ship's draught, and the increase in the ship's draught will increase its navigational resistance. This means that the effective thrust of the ship will be reduced, which will reduce the speed and energy efficiency of the ship.
- the pump-jet propulsion mode is analyzed. Because it is deployed and installed in the stern of the ship, the water intake is a single stern bottom water intake mode, and its influence and effect on the ship’s navigation is similar to the propeller propulsion mode. The result of the analysis of the force is also: the ship’s sailing resistance is increased, the ship’s effective thrust is reduced, and the ship’s speed and energy efficiency are reduced.
- the pump jet propulsion implements the curved suction jet push mode and because the pump jet propulsion device is deployed and installed inside the ship, the working water flow sucked by the pump jet propulsion device needs to rise a height before it can enter the spray pipe to obtain the impeller's energizing effect.
- the working water that stays in the pump-jet propulsion pipeline during the period from the water inlet to the spray-out from the water jet essentially becomes a part of the ship’s weight.
- the weight gain of the ship caused by the internal working water flow should not be underestimated. It will lead to an increase in the ship's own weight and an increase in the ship's draught, which will further lead to an increase in the ship's sailing resistance.
- the working water flow inside the pump jet propulsion pipeline needs to change the direction of the flow through the elbow, which is easy to form turbulence or eddy current loss at the inner bending part of the elbow, which is also a factor that weakens the total thrust output of the pump jet propulsion, and will also cause ships. Speed and energy efficiency are reduced.
- the propeller power transmission system and structure are generally complex.
- the propeller power transmission system and structure of large ships, especially large surface ships such as aircraft carriers, can be described as very complicated, requiring a considerable amount of ship storage capacity, resulting in a waste of effective storage capacity of the ship;
- the bottom-direction water inflow is implemented by pump jet propulsion, and its water inflow efficiency is not as high as that of water inflow;
- Pump jet propulsion implements bottom water inflow. When navigating in waters with a lot of weeds or debris, the water inlet is easily blocked and affects the water intake, resulting in lower propulsion efficiency or even failure;
- Pump jet propulsion implements bottom-injection water, shallow water navigation is easy to suck in the gravel and gravel in the water area, causing mechanical damage to the propulsion device;
- the ship obtains the driving force that supports the ship to overcome the sailing resistance and sail forward.
- the sailing resistance of the ship increases rapidly in a quadratic ratio to the speed.
- the sailing speed increases, it increases.
- the ship is stable at that speed and sails at a constant speed. If the ship’s propulsive force is increased to be greater than the total resistance of the ship at the speed, the ship will accelerate to sail to obtain a higher sailing speed.
- the total resistance of the ship increased due to the further increase in speed is equal to the increased propulsion force of the ship , The ship stabilizes at the new higher speed and sails at a constant speed.
- Ship propulsion depends on the conversion of energy consumed by the ship's power system. Increasing the propulsion power can increase the speed and increase the water range of the ship. However, increasing the propulsion power means that the increased energy consumption of the ship will inevitably increase the cost of the ship's navigation. When the economic benefits that can be achieved by the ship at high speed are not as high as the high cost caused by excessive fuel consumption of the ship, the high speed of the ship is not worth the loss, which means that the energy efficiency of the ship is low, which is also the reason why the ship speed and energy efficiency are generally low today. one.
- the ship's speed and energy efficiency are determined by the combined action of the ship's sailing resistance and the ship's propulsion, reducing the ship's sailing resistance and improving the ship's speed and energy efficiency.
- this kind of axial flow jet propulsion device and the deployment and installation of the axial flow jet propulsion device into the bow water inflow and direct suction jet propulsion mode allow the promotion and application to any ship including submersible devices, so it also contributes to the overall Solving the problem of generally low ship speed and energy efficiency, ushering in the era of global high speed.
- the steering torque of the ship's stern and rudder steering method is small, which supports the difficulty of the ship's rapid steering change, and it is inconvenient for the ship to make emergency avoidance.
- the stern rudder of a ship is generally set as a single rudder and is deployed and installed on the center line of the stern of the ship.
- the direction changing force obtained by the deflection of the rudder blade is very short relative to the lever arm of the ship's central axis, and the resulting direction changing moment is small; that is, the double rudder method is adopted.
- Deployment the two rudders are deployed and installed off the center line of the stern of the ship.
- the direction change force obtained by the deflection of the two rudder and rudder blades has increased relative to the length of the lever arm of the ship's central axis, and the resulting direction change torque follows an increase, but the increase is still limited , The rudder effect is still not obvious.
- the distance between the bow and the stern rudder of the ship is close to the length of the ship.
- the change of direction of the stern rudder reflects that it takes a process to change the direction of the bow and cannot respond quickly. This is especially true for large ships and long and narrow ships. Turning a turn requires a large turning radius, which is not convenient for ships to make emergency evasion and is not suitable for the era of high speed.
- the existing technology has developed the rapid change of ship's direction using the pod propeller and rudder, and the setting of a specialized bow change propulsion device at the bulbous bow of the ship. Due to the implementation of the coordinated change of the ship's bow and stern, this technology can significantly increase the speed of the ship's response to the change of direction and support the ship's emergency avoidance.
- the axial flow jet propulsion device and the axial flow jet propulsion device are deployed and installed into the bow water intake and direct suction jet propulsion modes as technological innovations, and their popularization and application are expected to promote the realization of a generally high speed era.
- the realization of the era of universal high speed will create incalculable economic and social value for the world. Because:
- Water transportation is a mode of transportation that uses ships as vehicles. It uses natural rivers, lakes, and seas as roads and also includes very few artificial waterways. Unlike land transportation, which requires huge investment in the construction and maintenance of roads (high-speed railways and expressways), it does not occupy or occupy less land; , Compared with the land transportation mode with railway as the main body, the biggest advantage lies in: heavy load, low energy consumption and low transportation cost.
- Speed is an important indicator of marine military power. The advent of the era of generally high speed will also affect revolutionary changes in marine military technology. For example, if the instantaneous speed of an aircraft carrier can reach or exceed 100 knots, it may cause major changes in the take-off method of carrier-based aircraft and further lead to the structure of the aircraft carrier. Changes.
- direct suction and injection propulsion devices and the implementation of direct suction and injection propulsion deployment and installation mode for forward water inflow can achieve a significant improvement in the energy efficiency of ships' navigation.
