Description

Rotating inertia impeller

Technical field

The invention relates to the field of power machinery, and in particular to a rotary inertia impeller.

Background technique

1. People have pursued the history of inertia for a long time and have achieved many achievements. For example, in the implementation of rocket launch, a high-speed unpowered inertial force stroke is utilized. The four-stroke internal combustion engine generates power only in one stroke, and the other strokes are completed by the high-speed rotational inertia of the crankshaft slider, and the upper and lower dead points are passed by inertia. The mechanical rotary gyroscope reaches hundreds of thousands of revolutions per minute, and the high-speed rotary inertia ensures stable high precision. The inertia flywheel relies on a large moment of inertia and a rotational inertia moment to store energy. Cars or airplanes move from low gear, high fuel consumption and slow speed to high speed, low fuel consumption or oil stop, and rely on kinetic energy and inertia. They both increase efficiency and save energy, and have become a model for high-speed inertia.

However, prior art turbines, wind turbines, blades of steam turbines, as well as rotors or propellers of aircraft, propellers of ships, pole poles of electric motors, etc., have not utilized their inertia for rotating blades at high speeds well. For example, many wind turbine blades and American Osprey helicopter rotors are both thick and small. Therefore, it is an urgent problem to fully utilize the high-speed rotational inertia of an impeller such as a turbine to improve the efficiency of the inertia impeller and to expand the application of the inertial impeller. New materials, new processes, and new computational simulations have provided support for this.

2. Blades, rotors, propellers or pole armatures of various cross-sections and shapes, collectively referred to as blades. The runners or rotors formed by them are collectively referred to as impellers. An inertial blade or inertial impeller is used for inertia. The shape and cross-section of the inertial blades are ever-changing. As a unified mechanical function, it can be summarized as:

(1) The moment of inertia M is proportional to the moment of inertia I and the angular acceleration ε, ie M=Iε. The greater the moment of inertia, ie, the moment of inertia I, the greater the inertia and moment of inertia, the higher the power, and the better the efficiency. Therefore, we must strive for I to maximize. I depends on shape, size, quality, mass distribution and centroid The distance to the axis. I is limited by technology, space, weight, materials, line speed, and economy.

(2) The kinetic energy K=Iω ² /2 of the rigid body rotating around the fixed axis is also to maximize the moment of inertia I.

(3) The larger the angular velocity ω of high-speed stable rotation, the larger the kinetic energy K, the higher the power, and the better the efficiency. Therefore, we must strive for maximizing ω, but it is limited by critical speed, driving line speed and material.

Therefore, how to achieve the proper maximization of I and ω through the inertial impeller structure is the key to increase the inertia and inertia moment of the impeller and increase the power.

3. The characteristics of the rotational inertia of a rotating object are:

(1) Keep the state of the original ω and kinetic energy K unchanged, and the axis always rotates in the predetermined direction. The rotation of the vertical axis is such that the rotation of the horizontal axis is also the same, rather than offsetting the potential or kinetic energy of the upper and lower portions of the runner.

(2) As the external force continues to drive, the original ω and K increase. The external force is continuously driven, and ω and K increase continuously; the external force is intermittently driven, and ω and K are intermittently increased.

(3) The longer the driving time or the more the number of intermittent driving, the more ω and K increase, up to the limit. However, before the limit is reached, once the load is applied, ω and K immediately stop increasing, and the impeller enters a uniform speed motion.

It is an object of the present invention to provide a scheme for increasing the I and ω of a rotating impeller according to these characteristics of the inertia of the object, and to improve and utilize the rotational inertia of the impeller, thereby improving efficiency and saving energy.

The driving force acts on the blade or drives the blade through the shaft 1; it does not act on the inertial weight.

2. The blade is an inertia blade, and the inertia blade is a blade having a radius of revolution R0 ≥ 0.72 times the blade length R1.

3. The above-mentioned rotary inertia impeller further includes an external boosting device for driving the rotary inertia impeller to rotate when starting, and separating from the rotating inertia impeller after the rotating inertia impeller reaches the set rotational speed, and disconnecting the power connection.

4. The external power assisting device is a gear assisting device comprising a gear fixed to the shaft, an external gear train, and a power source connected to the external gear train; the power source is a power source disposed on the ground .

5. In a preferred embodiment of the above-described rotary inertia impeller, the inner end of the inertia vane is smaller than the outer end, and the inner end of the inertia vane is provided with a reinforcing ring.

6. The rotating inertia impeller is used as a rotor of a helicopter; when the helicopter is started, the rotary inertia impeller is driven by external power, and the external assist is removed after the rotating inertia impeller reaches the set speed, and the helicopter is driven to rotate by its own power system. The inertia impeller continues to rotate.

7. The rotary inertia impeller is used as an impeller of a steam turbine; when the steam turbine is started, the rotary inertia impeller is driven by an external power, and the external assist is removed after the rotary inertia impeller reaches a set speed, and the steam turbine drives the rotary inertia impeller through the high pressure steam to continue. Turn.

Experiments prove that the above technical solution can enable the power equipment to efficiently utilize the inertia action of the blade and the inertia recircle to achieve the purpose of improving efficiency and saving energy. In particular, when the moment of inertia I of the second inertial weight 9 is large, the effect is more pronounced.

detailed description

The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIGS. 1 to 9, the reference numerals of the present embodiment include: a shaft 1, a bracket 2, a reinforcing ring 4, an inertia blade 7, a first inertial weight 8, a second inertial weight 9, a base 16, a magnetic pole. Armature 17, electromagnetic stator 18, center bracket 20, bracket arm 21, fuselage 22, weight 23 suspended from the outside, column 24, bearing 28, landing wheel 29, casing 31, external gear train 32, gear 33 .

The rotary inertia impeller of all embodiments comprises a shaft and a blade, the inner end of the blade is connected with the shaft; the blade is a common blade or an inertia blade 7, and the inertia blade is a blade having a radius of revolution R0 ≥ 0.72 times the blade length R1; wherein R0 is actual The radius of gyration of the blade to the axis of the shaft, the actual blade is the portion of the blade from the blade root to the tip; R1 is the radial distance between the center of the shaft 1 and the outermost end of the inertia blade 7, ie the axis to The distance from the tip of the blade;

The rotary inertia impeller further includes a first inertial weight 8 that is fixed or hinged to the outer end of the inertia blade 7 and has a weight greater than 0.38 times the total weight of the inertia blade, or/and includes a second inertia that is fixed by the bracket 2 and the shaft 1 The recirculation 9, the moment of inertia of the second inertial weight 9 is a times the total moment of inertia of the blade, and the range of a is [1, 8]. According to a specific embodiment, an optimal value interval may be further preferred within this interval depending on the specific situation.

In the implementation, the values of a>8 cannot be taken in the implementation, but the larger the moment of inertia, the more difficult the asymmetric deformation, dynamic balance and vibration are solved, and the engineering application has many disadvantages.

For a wheel with a wheel on the shaft, the blade root is fixed to the blade at the edge of the wheel. The length of the blade refers to the blade root to the tip of the blade, and the moment of inertia and radius of gyration R0 of the blade to the axis are calculated; Still refers to the radial distance between the center of the shaft 1 and the outermost end of the blade.

The rotary inertia impeller further includes an external boosting device for driving the rotary inertia impeller to rotate when starting, and separating from the rotating inertia impeller after the rotating inertia impeller reaches the set rotational speed, and disconnecting the power connection. The actuating force of the external booster acts on the shaft 1 or on the inertial weight, rather than on the blades.

There are three types of external power assist devices: gear assist devices, suspension weight boosters, and manual boosters;

(1) A gear assisting device comprising a gear fixed to the shaft 1, an external gear train, and a power source connected to the external gear train; the power source is a power source disposed on the ground.

(2) The suspension weight assisting device locks the second inertial weight ring 9 on the ground and hangs the weight 23 at its outer side. Then, suddenly unlocked, the weight 23 is free to fall, and the second inertial weight 9 is pulled to rotate downward. The weight 23 is grounded and automatically disengages from the second inertia weight 9. This device is generally used for a vertically arranged rotating inertia impeller structure.

(3) Manual boosting device, that is, manually pushing, pulling, and rotating the first inertial weight ring 8. This device is generally used for a small rotating inertia impeller structure.

The driving force of the inertia motor, the inertia turbine, and the inertial steam turbine adopts an appropriate input method of dividing the time or reducing the flow rate in a time-division manner, and still can ensure the basic stability of the output torque of the rotor shaft end, which can improve the efficiency and save energy.

Those skilled in the art can make adjustments according to the embodiments as needed to adapt to specific applications.

The inertia impeller of Fig. 1 has three inertia blades 7 disposed uniformly around the axis 1, and the angle between the inertia blades 7 is 120°, and the inner end of the inertia blade 7 is connected to the shaft 1. The inertia vanes 7 may be vanes, rotors or propellers of various cross-sections and shapes, characterized by a small inner end and a large and heavy outer end. The radius of gyration R0 of the inertia blade 7 is 0.72 times the blade length R1. It can be used in aircraft, engines, fans, etc.

The R0 of the existing ceiling fan, helicopter rotor, turbine or steam turbine blade is less than 0.72R1, and the effect of fully utilizing the blade inertia is not achieved. The inertial action of the inertia blade 7 of the present invention has a very significant energy saving effect.

2 is an inertia impeller composed of four inertia blades 7 and a first inertial weight ring 8. The inner end of the inertia blade 7 is connected to the shaft 1. The outer end of the inertia blade 7 is consolidated or hinged with the first inertial weight 8 . The purpose of the articulation is to allow the outer end to be somewhat biased when the inertia blade 7 is long. This inertial impeller can be widely used in various power equipment.

Fig. 3a is a schematic view of a rotor of an electric motor having two pole armatures 17 disposed uniformly circumferentially about the shaft, the angle between the two pole armatures 17 being 180°.

Figure 3b is a simplified analysis of the mechanical analysis of the two pole armatures 17 into two inertia blades 7. The difference from the pole armature 17 of the modern motor rotor is that the size and weight of the pole armature 17 are simplified to the inertia vanes 7 while making the radius of gyration of the inertial blade mass in order to fully exert the inertia of the high speed rotation of the rotor pole armature 17. R0 ≥ 0.72 times the inertia blade length R1. In this way, the inertia of the magnetic pole armature 17 of the high speed rotor can be utilized to the utmost extent, and the energy saving effect is remarkable.

The unmanned helicopter of Fig. 4 has four rotary inertia impellers, and each of the rotary inertia impellers is composed of three inertia blades 7 and a first inertial weight ring 8. Their structure and quality are identical. The inertia blades 7 of the inertia impellers on both sides are rotated in opposite directions. The inner end of the inertia blade 7 is connected to the shaft 1, and the outer end is fixed or hinged to the first inertial weight 8 . A device such as a controller is placed in the center bracket 20. Four bracket arms 21 are symmetrically mounted, and their outer ends are respectively fixed to the shaft 1 of the rotary inertia impeller. The rotating inertia impeller does not need to be tilted, and the flight in different directions can be achieved by adjusting the speed of each rotating inertia impeller.

When the rotational inertia of the four rotating inertia impellers is too large, when the self-powered starting is slow or unable to start, the external assisting device is used to simultaneously drive the shafts of the four rotating inertia impellers to help the inertial impellers start the rotation, and then after the helicopter is started. Evacuation. For electric toys straight For the lift, the initial rotational speed of the rotating inertia impeller can be obtained by the external power source driving its own rotary inertia impeller drive system.

Figure 5a is a top view of another helicopter and Figure 5b is a side view of the helicopter.

Six rotating inertia impellers are symmetrically distributed on both sides of the long fuselage 22. Each impeller shaft 1 is fixed to the outer end of the bracket arm 21. Each of the rotational inertia impellers is composed of four inertia blades 7 and a first inertial weight ring 8, and the adjacent two inertia blades 7 are at an angle of 90°. The inner end of the inertia blade 7 is connected to the shaft 1, and the outer end is fixed or hinged to the first inertial weight 8 . The rotation directions of the inertia blades 7 of the pair of right and left rotating inertia impellers are opposite. The radius of the inertia blade 7 is R1 = 1.5 m. The spacing between the two rotating inertia impellers is S = 1 m. Their structure and quality are identical. The cross-sectional curvature of the inertia vanes 7 is determined by the required lift and power. The rotating inertia impeller can be made into a deflectable type. After vertical take-off, the rotating inertia impeller is tilted forward to provide lift and tension.

When the rotational inertia of the six rotating inertia impellers is too large, it is difficult to change the flight direction by using the blade pitch or speed regulation. The propeller shaft can be rotated to change the forward direction. The radius of the illustrated propeller is R1 = 80 cm. If the nose propellers are one on each side, the speed of the propeller can be adjusted to change the direction of travel. During the helicopter lifting process, the nose propeller is in a free state.

The power of the rotating inertia impeller is mounted in the fuselage by a fuel machine or/and a battery motor, and the shaft 1 of the six inertia impellers is driven to rotate by a transmission shaft-gear system.

The front and rear of the fuselage are provided with a land wheel 29.

The use of the first inertial weight 8 greatly increases the weight of the helicopter, but the resulting large lift, especially the large rotational kinetic energy, is conducive to the stable flight of the helicopter. The first inertia weight 8 has a large moment of inertia I, which is difficult to start. However, since the helicopter is initially on the ground, the rotary inertia wheel can be accelerated to the rated speed by means of a power assist device provided on the ground, so that the helicopter can be smoothly take off. After the helicopter takes off, only a small energy input is required to keep the six impellers rotating stably. The helicopter receives the energy provided by the external booster on the ground to achieve high-speed operation, reducing the consumption of fuel loaded by itself, thereby greatly increasing the cruising range, thus saving fuel on the aircraft and high-speed stable long-term flight.

Multiple rotary inertia impellers provide higher steady speed, greater momentum moments and lift, and are more stable and safer. One or two power motors can continue to fly when they are damaged. It can also fall slowly by the inertia of the inertia impeller. The longer the inertia blade 7, the larger the number, and the more the impeller, the greater the load carrying capacity. Different bearing capacity of 2 tons or less, 4 to 12 rotating inertia impellers, and manned or unmanned helicopter series will become effective tools for short-distance traffic and are widely used in various aspects.

The inertia impeller wind turbine of Figure 6 consists of four inertia blades 7 and a first inertial weight 8 that is consolidated or hinged at the tip. The radius of the rotary inertia impeller is 50 m, and the inner end of the inertia blade 7 is small and consolidated with the shaft 1. In order to prevent the inertia blade 7 from being too long and the inner end being excessively stressed, the inner end of the inertia blade 7 is provided with a reinforcing ring 4 to improve the service life of the inertia blade 7. The top end of the column 24 is connected to the chassis, and the lower end is consolidated with the base 16.

The difference between this type of inertial wind turbine and the existing wind turbine is that its moment of inertia is much larger than that of the existing wind turbine. The first inertia recircle 8 can be manually pushed and pulled by human power to assist the starting. Such an inertial impeller wind turbine is more efficient than existing wind turbines.

The widely used wind turbine inertia blade is just the opposite. It is a full cantilever with a large inner end and a small outer end. There is no first inertial weight ring 8 and a reinforcing ring 4, and the structure is firm and less manual care is used.

The left three of the eight impellers in the steam turbine of Fig. 7 are rotary inertia impellers, and the outer ends of their inertia blades 7 are connected to a first inertial weight ring 8. The five short impellers on the right side are not connected to the first inertial weight ring 8. The eight impellers and a second inertial weight ring 9 consolidated by the bracket 2 and the shaft 1 together form an integral rotary inertia impeller turbine, referred to as an inertial turbine. Both ends of the shaft 1 are supported by bearings 28.

When there is no inertia blade 7 and first inertia recircle 8 in Fig. 7, all of the conventional blades of the prior art are used, and at the same time, they are consolidated with the second inertial weight ring 9, which together constitute an integral rotary inertia impeller turbine, referred to as an inertial turbine. This solution can be applied to the retrofit and upgrade of existing steam turbines.

It can be seen that the above two inertia steam turbines have a second inertial weight 9 which is fixed with the shaft 1, so that the inertia of the inertia turbine is much larger than that of the existing steam turbine. The greater the moment of inertia of the second inertial weight 9 is, the greater the inertia of the inertia turbine is, but it cannot be infinitely large, and it is limited by factors such as technology, material, linear velocity, external force, space, and the like. Turbine shaft and The connection of the blades is various, and the length or number of the blades varies greatly. The optimal range of the moment of inertia of the second inertial weight 9 and the multiple of the total moment of inertia of the blade is [1, 8].

The inertia turbine has a large moment of inertia and is difficult to start. It is provided with an external booster to help start and increase the speed. The power assisting device includes a gear 33 that is affixed to the shaft 1, an external gear train 32, and an external high power motor. The high power motor pushes the gear 33 through the shifting gear train 32 to help the shaft 1 increase the initial speed, and after the required speed is reached, the booster is evacuated.

The high-pressure, high-temperature drive steam of the inertia turbine adopts an appropriate input method of time-breaking or time-division to reduce the flow rate, and still can ensure the basic stability of the output torque of the rotor shaft end, which can improve the efficiency and save energy.

Figure 8a is a bottom view of a vertical axis turbine and Figure 8b is a side view. The water bucket type inertia blade 7 is at the lower portion. A second inertial weight 9 is at the top to form an integral rigid inertia turbine. The hydraulic force P1 pushes the inertia blade 7, and the linear velocity of the action point ≤ the linear velocity of the water flow itself, otherwise the external force stalls. The casing 31 and the base 16.

When the inertia vanes 7 of Fig. 8a are replaced by conventional vanes of the prior art and combined with the second inertial sheave 9, they also form an integral inertia turbine. This solution can be applied to the retrofit of existing turbines.

It can be seen that the above two inertia turbines have a second inertial weight 9 consolidating with the shaft 1, so that the inertia of the inertia turbine is much larger than that of the existing turbine. Due to the limitation of the space of the turbine engine room, and the structural deformation, dynamic balance and vibration problems caused by the asymmetric hydraulic drive, the moment of inertia of the heavy circle 9 is more limited. The optimal range of the moment of inertia of the second inertial weight 9 and the multiple of the total moment of inertia of the blade is [1, 4]. The larger the space and the better the technology, the larger the multiple.

The difference between the inertia turbine and the existing turbine is that the inertia turbine is fixed with the second inertia weight 9 and the moment of inertia is much larger than that of the conventional turbine, and the inertia effect of the turbine blade can be exerted.

The driving hydraulic force of the inertia turbine adopts an appropriate input method of dividing the time or reducing the flow rate in a time-division manner, and still can ensure the basic stability of the output torque of the rotor shaft end, which can improve the efficiency and save energy.

An external booster is used to help start and increase the speed of the inertia turbine. The external boosting device can be driven by a gear assisting device as shown in FIG. 7, including being fixed on the shaft 1. The gear 33, the external gear train 32 and a power source connected to the external gear train; the power source is a power source disposed on the ground.

For the horizontal axis of the turbine, there is another way of assisting: locking the second inertial weight 9 on the ground and hanging the weight 23 on its outer side. Then, suddenly unlocked, the weight 23 is free to fall, and the second inertial weight 9 is pulled to rotate downward. The weight 23 is grounded and automatically disengages from the second inertia weight 9.

Fig. 9a is a front view of the horizontal axis motor, and Fig. 9b is a plan view. Similar to Fig. 3, the rotor pole armature is equivalent to the inertia blade 7. These inertia blades 7 are combined with a second inertial weight 9 to form a rigid body inertia motor rotor that rotates together. The radius R of the second inertial weight 9 is larger than the rotor radius R1.

When the inertia blade 7 of Fig. 9a is replaced by a conventional magnetic pole armature blade of the prior art and combined with the second inertia weight ring 9, it is still collectively formed as an integral inertia motor rotor. This solution can be applied to the retrofit of existing motor rotors.

It can be seen that the above two inertia motor rotors have a second inertial weight 9 that is fixed with the shaft 1, so that the moment of inertia of the inertia motor is much larger than the moment of inertia of the existing motor. Since the space of the motor on the ground is large, the moment of inertia of the heavy circle 9 can be relatively large; however, the total moment of inertia of the pole armature blades is relatively large, so the moment of inertia of the second inertial weight 9 and the total moment of inertia of the pole armature blades The optimal range of multiples is [1,6].

Since the inertia of the rotor of the inertia motor is much larger, the high-speed rotational kinetic energy and the rotational inertia are large. The driving power of the inertial motor adopts an appropriate time-breaking or time-dividing input method to reduce the current flow, and the output torque of the rotor shaft end can still be ensured. Basic stability can both improve efficiency and save energy.

Both ends of the shaft 1 are supported by bearings 28. Electromagnetic stator 18.

An external booster is used to help start and increase the speed until the rated speed is reached. The boosting device can be the same as the boosting device of FIG. The prior art motor does not require the inertial action of the rotor pole armature to rotate at a high speed, so there is no second inertial weight 9 and the moment of inertia is much smaller.

The inertia impeller of the invention fully utilizes the rotational inertia of the object, thereby achieving the purpose of improving the efficiency of the inertial impeller and saving energy. The invention is a novel power machine, which can be widely used in the fields of water turbines, wind turbines, steam turbines, electric motors, airplanes and ships.

It will be readily understood by those skilled in the art that the scope of the present invention is obviously not limited to the specific embodiments. Those skilled in the art can make equivalent changes or substitutions to the related technical features without departing from the principles of the present invention, and the technical solutions after the modifications or replacements fall within the scope of the present invention.
