Description

Technical Field

[0001] The present invention relates to the technical field of electric energy storage systems, and in particular to an energy storage and recovery device for excess electricity of a generator. Background Art

[0002] A generator consists primarily of two parts: the stator and the rotor. The stator is the stationary portion of the generator, containing fixed magnets or electromagnetic coils. The rotor is the rotating portion of the generator, typically containing winding coils. When the generator is operating, the stator generates a stable magnetic field through permanent magnets or electromagnetic coils. Modern generators often use electromagnets to create a strong magnetic field to ensure efficient power generation. When the rotor rotates in the magnetic field, according to Faraday's law, a varying magnetic flux is generated in the rotor windings, inducing an electromotive force in the windings. This generated electromotive force drives current through the external circuit, achieving electrical energy output. The magnitude of this current is closely related to factors such as the rotor's rotational speed, the strength of the magnetic field, and the number of turns in the windings.

[0003] Some factories often save on electricity costs by using the main grid during low electricity prices and generators during peak hours. Generators are also used to maintain factory production during power outages, ensuring the efficiency of factory production. The power generated by a generator during operation must be greater than the power required by the load in the circuit to ensure stable operation. However, this results in energy loss and waste. Existing technologies use electronic speed regulators to adjust the shaft speed and output power according to the load in the circuit to reduce this energy loss and waste. However, this requires the circuit load to remain stable. Factories or workshops often use high-power machines. When a high-power load is suddenly connected to the circuit, the electronic speed regulator cannot react immediately and must instead increase the generator speed to increase the amount of power entering the circuit. This can easily cause voltage fluctuations and large current surges within the circuit, affecting circuit stability and potentially damaging equipment, which in turn affects production and results in economic losses. To address the problems of resource waste when the generator is running at high power, and voltage fluctuations and large current surges when connected to a high-power load during low power operation to ensure circuit operation, affecting circuit stability, a new approach has been proposed.

[0004] To this end, an energy storage and recovery device for the excess power of a generator is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide an energy storage and recovery device for the excess power of a generator. By setting an energy storage component, the excess power generated by the generator when it is running at a high power is stored. When a high-power load is connected to the circuit, the control component monitors the current change in the circuit and controls the speed change component to reduce the transmission ratio, so that the energy storage component is discharged instantaneously, maintaining the stability of the circuit, and preventing the circuit from being connected to a high-power load when the circuit is running at low power, which will cause voltage fluctuations and large current shocks in the circuit.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A device for storing and recycling excess electricity of a generator, comprising a generator, an energy storage component, a speed change component, and a control component; the energy storage component is mounted on one side of the generator, the two ends of the speed change component are respectively connected to the generator and the energy storage component, the control component is connected to one side of the speed change component, the speed change component comprises a driving shaft, a driving wheel, an adjusting rod 1, an adjusting shaft, a driven wheel, and a belt; the driving shaft is mounted between the energy storage component and the generator, two adjusting rods 1 are rotatably mounted on both sides of the driving shaft, the driving wheel is fixedly mounted on the driving shaft, the adjusting shaft is rotatably mounted between the adjusting rods 1, a plurality of adjusting rods 2 are movably connected to the adjusting shaft, a plurality of driven wheels are rotatably mounted between the adjusting rods 2, the belt cooperates with the driving wheel and the driven wheel, the generator drives the energy storage component to rotate through the speed change component, and when the circuit where the generator is located is connected to a load, the control component controls the adjusting rod 2 to extend so that the energy storage component drives the generator to rotate.

[0008] Preferably, the energy storage assembly includes a flywheel shaft, a flywheel, a radial bearing, a magnetic bearing, and a shell one, wherein the shell one is installed at one end of the generator, the flywheel shaft is rotatably installed at an internal axis position of the shell one and is fixedly connected to the adjustment shaft, the flywheel is fixedly installed on the flywheel shaft, the two radial bearing outer rings are fixedly installed on the inner side of the shell one, and the inner rings are connected to the flywheel shaft, and the outer ring of the magnetic bearing is connected to the inner side of the shell one and the inner ring is fixedly installed on the flywheel shaft.

[0009] In the above scheme, the rapid rotation of the flywheel is used to convert electrical energy into kinetic energy. When fluctuations occur in the circuit, the kinetic energy in the flywheel can be quickly converted into electrical energy to compensate for the circuit by adjusting the transmission ratio. At the same time, magnetic bearings are installed at both ends of the flywheel to reduce the friction between the flywheel and the casing.

[0010] Preferably, the control component includes a power supply, a current detection resistor, a relay, and a second shell; the second shell is connected to one end of the adjusting shaft, the power supply is fixedly installed inside the second shell and is electrically connected to the second adjusting rod, the current detection resistor and the relay are fixedly installed at one end of the power supply, and a port is installed on the outside of the generator, and the power supply, the current detection resistor, and the relay are electrically connected to the port.

[0011] In the above scheme, the power supply supplies power to the adjusting shaft, controlling the adjusting shaft to continuously contract. When a new load is connected to the generator, the current distributed to the current detection resistor decreases, generating a signal. At this time, the signal is transmitted to the relay, and the relay contacts are closed, connecting the power supply to the circuit. At this moment, the power supply and the generator simultaneously supply power to the load to prevent a large current shock. Because the adjusting rod 2 and the load are connected in parallel, the adjusting rod 2 is shunted and the power is reduced. At this time, affected by the centrifugal force, the adjusting rod 2 begins to extend. At this time, the transmission ratio is reduced. The energy storage component drives the generator to rotate at this moment, improving the power generation efficiency and ensuring that the current in the circuit is stable when the load is connected. At this time, the generator power is adjusted to meet the power demand after the load is added. After the circuit is stable, the relay is disconnected, and the power supply only provides energy to the adjusting rod 2. At this time, the adjusting rod 2 slowly shortens, and the generator drives the energy storage component to rotate and continue to store energy.

[0012] Preferably, an adjustment hole is opened on the outer side of the second shell, an adjustment hole is opened on the outer side of the second shell, a sliding rheostat is fixedly installed at one end of the power supply, the resistance adjustment part at the upper end of the sliding rheostat cooperates with the adjustment hole, and the sliding rheostat is electrically connected to the power supply and the adjustment rod.

[0013] In the above scheme, the sliding rheostat and the adjusting rod 2 are connected in series. Adjusting the resistance value of the sliding rheostat can change the power of the adjusting rod 2, thereby changing the speed of contraction of the adjusting rod 2, and then adjusting the ratio of the amount of electricity used by the generator to power the load and the amount of stored electricity. While the generator is running, the circuit is kept stable while the excess electricity is stored in the energy storage component.

[0014] Preferably, an adjustment component is fixedly installed at one end of the generator, and the adjustment component includes an adjustment inner ring, an adjustment block, an adjustment spring, and an adjustment outer ring. The adjustment inner ring is fixedly installed on the generator, and a mounting groove is provided on the adjustment inner ring. One end of the adjustment spring is installed at the bottom of the mounting groove, the adjustment block is connected to the other end of the adjustment spring, and the adjustment outer ring is rotatably installed on the adjustment inner ring.

[0015] In the above scheme, when the external machine drives the generator to rotate, the speed of the outer ring is adjusted to be greater than that of the inner ring, and the outer ring drives the inner ring to rotate to make the generator generate electricity. When the energy storage component discharges, the speed of the inner ring is greater than that of the outer ring. At this time, the adjustment block is stuck in the groove, and the inner ring does not drive the outer ring to rotate, thereby preventing damage to the machine.

[0016] Preferably, a sliding plate is installed at the lower end of the energy storage component, and a fixed plate is connected to the lower end of the sliding plate. Slide grooves are opened on both sides of the fixed plate, and the sliding plate is slidably connected in the slide grooves. There are small triangular protrusions on the surface of the fixed plate.

[0017] In the above scheme, as the energy storage component continues to store more energy, its horizontal displacement with the generator continues to change. Installing a slide plate and a fixed groove can limit its displacement in other directions. At the same time, a triangular protrusion is provided on the surface of the fixed plate to increase friction and keep the belt always taut.

[0018] Preferably, a fixing bracket is fixedly mounted on one side of the fixing plate, and the fixing bracket is fixedly connected to the adjusting rod.

[0019] In the above scheme, support force is provided to the speed change assembly to prevent the speed change assembly from exerting excessive gravity on the generator shaft. At the same time, the force between the fixed frame and the adjusting rod 1 and the force between the adjusting shaft and the inner shaft of the energy storage assembly are used to jointly drive the energy storage assembly to slide, thereby preventing excessive force between the adjusting shaft and the inner shaft of the energy storage assembly from affecting the energy storage assembly.

[0020] Preferably, a return spring 1 is provided at one end of the adjusting rod 1, and a return spring 2 is provided at the inner end of the adjusting rod 2, and the initial state of the return spring 1 is a compressed state.

[0021] In the above scheme, the return spring 1 and the return spring 2 can ensure that the belt is always in a taut state during the entire energy storage process, increase the friction between the driving wheel and the driven wheel, and improve the conversion efficiency. At the same time, the adjustment rod 2 is retracted inward under the action of the power supply. When the flywheel storage component begins to release kinetic energy, the power is turned off. At this time, the potential energy of the return spring 1 is less than that of the return spring 2. At the same time as the flywheel storage component begins to release kinetic energy, the adjustment rod 2 is slowly extended to increase the transmission ratio and ensure the output power.

[0022] Preferably, the adjustment shaft and the driving shaft axis are at the same horizontal position.

[0023] In the above solution, it is ensured that the energy storage component is displaced horizontally and is not subjected to forces in other directions. At the same time, it is ensured that the pressure on multiple driven wheels when in contact with the belt is uniform, thereby extending the service life.

[0024] Preferably, a pressing block is provided at the lower end of the second adjusting rod, and a switch is provided at the inner end of the adjusting shaft, and the switch is electrically connected to the power supply.

[0025] In the above scheme, when the adjusting rod 2 is retracted to the limit, that is, when the pressing block presses the switch, the power is cut off, and the adjusting rod 2 is no longer powered and is in a state where it can move freely. It is pushed outward slowly by the force of the reset spring 2. At this time, the transmission ratio of the speed change assembly becomes larger, the speed of the flywheel energy storage assembly becomes faster, and it starts to drive the generator to generate electricity.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. A device for storing and utilizing excess electricity from a generator. Compared with the prior art, the present invention provides a flywheel energy storage assembly, which uses an electric motor to drive a flywheel in the flywheel energy storage assembly to rotate at high speed through a speed change assembly, thereby converting excess electrical energy generated by the generator into kinetic energy for the flywheel rotation and storing it. When the energy storage reaches its maximum value, the external drive to generate electricity for the generator is stopped, and the flywheel energy storage assembly is used to drive the generator to generate electricity. The present invention stores excess electrical energy generated by the generator, thereby avoiding waste of resources.

[0028] 2. A device for storing and utilizing excess power from a generator. The present invention cooperates with a control component and a speed-changing component. When a new load is connected to the generator, a current detection resistor generates a signal, prompting the contacts in the relay to close, connecting the power supply to the circuit. The power supply and the generator are used to simultaneously power the load to prevent a large current shock. At the same time, since the second adjusting rod is connected in parallel with the load, the power of the second adjusting rod is reduced. Under the action of the second reset spring, the second adjusting rod begins to extend. At this time, the transmission ratio between the generator and the energy storage component is reduced, so that the energy storage component drives the generator to rotate, increasing the power generation power and ensuring the stability of the current in the circuit when the load is connected.

[0029] 3. A device for storing and utilizing excess power from a generator. The present invention connects an adjusting rod 2 and a sliding rheostat in series. By changing the resistance of the sliding rheostat connected to the circuit, the current passing through the adjusting rod 2 is changed, thereby controlling the contraction speed of the adjusting rod 2, and further adjusting the ratio of the amount of power used by the generator to power the load and the amount used to store power. After adjustment, as much power as possible can be stored in the energy storage component while ensuring circuit stability. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of driven wheels 35 are rotatably mounted between the adjusting rods 2 341, and the belt 36 cooperates with the driving wheel 32 and the driven wheel 35. The generator 1 drives the energy storage component 2 to rotate through the speed change component 3. When the circuit where the generator 1 is located is connected to the load, the control component 4 controls the adjusting rod 2 341 to extend so that the energy storage component 2 drives the generator 1 to rotate.

[0042] As an embodiment of the present invention, refer to Figure 3 and Figure 5 The energy storage component 2 includes a flywheel shaft 21, a flywheel 22, a radial bearing 23, a magnetic bearing 24, and a shell 25. The shell 25 is installed at one end of the generator 1. The flywheel shaft 21 is rotatably installed at the internal axis position of the shell 25 and is fixedly connected to the adjustment shaft 34. The flywheel 22 is fixedly installed on the flywheel shaft 21. The outer rings of the two radial bearings 23 are fixedly installed on the inner side of the shell 25, and the inner rings are connected to the flywheel shaft 21. The outer ring of the magnetic bearing 24 is fixedly installed on the inner side of the shell 25, and the inner ring is connected to the flywheel shaft 21.

[0043] In the above embodiment, the rapid rotation of the flywheel 22 is used to convert electrical energy into kinetic energy. When fluctuations occur in the circuit, the kinetic energy in the flywheel 22 can be quickly converted into an electrical energy compensation circuit by adjusting the transmission ratio. At the same time, magnetic bearings 24 are installed at both ends of the flywheel 22 to reduce the friction between the flywheel 22 and the housing.

[0044] As an embodiment of the present invention, refer to Figure 1 、 Figure 4 and Figure 5 The control component 4 includes a power supply 41, a current detection resistor 42, a relay 43, and a second housing 44; the second housing 44 is connected to one end of the adjustment shaft 34, the power supply 41 is fixedly installed inside the second housing 44 and is electrically connected to the second adjustment rod 341, the current detection resistor 42 and the relay 43 are fixedly installed at one end of the power supply 41, and a port 11 is installed on the outside of the generator 1, and the power supply 41, the current detection resistor 42, and the relay 43 are electrically connected to the port 11.

[0045] In the above embodiment, the power supply 41 supplies power to the adjustment shaft 34, controlling the adjustment shaft 34 to continuously contract. When a new load is connected to the generator 1, the current divided by the current detection resistor 42 decreases, generating a signal. At this time, the signal is transmitted to the relay 43, and the contacts of the relay 43 are closed, connecting the power supply 41 to the circuit. At this moment, the power supply 41 and the generator 1 simultaneously supply power to the load to prevent a large current shock. Because the adjustment rod 2 341 is connected in parallel with the load, the adjustment rod 2 341 is shunted and the power is reduced. At this time, under the influence of centrifugal force, the adjustment rod 2 341 begins to extend. At this time, the transmission ratio is reduced. At this moment, the energy storage component 2 drives the generator 1 to rotate, improving the power generation efficiency and ensuring that the current in the circuit is stable when the load is connected. At this time, the power of the generator 1 is adjusted to meet the power demand after the load is added. After the circuit is stable, the relay 43 is disconnected, and the power supply 41 again provides energy only to the adjustment rod 2 341. At this time, the adjustment rod 2 341 slowly shortens, and the generator 1 drives the energy storage component 2 to rotate and continue to store energy.

[0046] As an embodiment of the present invention, refer to Figure 2 and Figure 4 An adjustment hole 441 is provided on the outside of the second shell 44. A sliding rheostat 412 is fixedly installed on one end of the power supply 41. The resistance adjustment part of the upper end of the sliding rheostat 412 cooperates with the adjustment hole 441. The sliding rheostat 412 is electrically connected to the power supply 41 and the adjustment rod 341.

[0047] In the above embodiment, the sliding rheostat 412 and the adjusting rod 2 341 are connected in series. Adjusting the resistance value of the sliding rheostat 412 can change the power of the adjusting rod 2 341, thereby changing the speed of contraction of the adjusting rod 2 341, and then adjusting the ratio of the amount of electricity used by the generator 1 to power the load and the amount of stored electricity, while maintaining the circuit stability when the generator 1 is running and storing excess electricity in the energy storage component 2.

[0048] As an embodiment of the present invention, refer to Figure 1 and Figure 7 An adjustment component 12 is fixedly installed at one end of the generator 1. The adjustment component 12 includes an adjustment inner ring 121, an adjustment block 122, an adjustment spring 123, and an adjustment outer ring 124. The adjustment inner ring 121 is fixedly installed on the generator 1. A mounting groove 1212 is provided on the adjustment inner ring 121. One end of the adjustment spring 123 is installed at the bottom of the mounting groove 1212. The adjustment block 122 is connected to the other end of the adjustment spring 123. The adjustment outer ring 124 is rotatably installed on the adjustment inner ring 121.

[0049] In the above embodiment, when the external machine drives the generator 1 to rotate, the speed of the adjusting outer ring 124 is greater than that of the adjusting inner ring 121, and the adjusting outer ring 124 drives the adjusting inner ring 121 to rotate so that the generator 1 generates electricity. When the energy storage component 2 discharges, the speed of the adjusting inner ring 121 is greater than that of the adjusting outer ring 124. At this time, the adjusting block 122 is stuck in the groove, and the adjusting inner ring 121 does not drive the adjusting outer ring 124 to rotate, thereby preventing damage to the machine.

[0050] As an embodiment of the present invention, refer to Figure 1 and Figure 6 A sliding plate 26 is installed at the lower end of the energy storage component 2, and a fixed plate 27 is connected to the lower end of the sliding plate 26. Slide grooves 271 are opened on both sides of the fixed plate 27. The sliding plate 26 is slidably connected in the slide grooves 271, and there are small triangular protrusions on the surface of the fixed plate 27.

[0051] In the above embodiment, the horizontal displacement of the energy storage component 2 and the generator 1 keeps changing as the energy storage continues to increase. The installation of the slide plate and the fixing groove can limit its displacement in other directions. At the same time, a triangular protrusion is provided on the surface of the fixing plate 27 to increase the friction force so that the belt 36 always remains in a taut state.

[0052] As an embodiment of the present invention, refer to Figure 2 and Figure 6 A fixing frame 272 is provided on one side of the fixing plate 27 , and the fixing frame 272 is fixedly connected to the adjusting rod 33 .

[0053] In the above embodiment, a supporting force is provided to the speed change assembly 3 to prevent the speed change assembly 3 from exerting excessive gravity on the generator 1 shaft. At the same time, the force between the fixing frame 272 and the adjusting rod 1 33 and the force between the adjusting shaft 34 and the inner shaft of the energy storage assembly 2 are used to jointly drive the energy storage assembly 2 to slide, thereby preventing the excessive force between the adjusting shaft 34 and the inner shaft of the energy storage assembly 2 from affecting the energy storage assembly 2.

[0054] As an embodiment of the present invention, refer to Figure 5 A return spring 331 is provided at one end of the adjusting rod 1 33 , and a return spring 342 is provided at the inner end of the adjusting rod 2 341 . The initial state of the return spring 1 331 is a compressed state.

[0055] In the above embodiment, return spring 1 331 and return spring 2 342 ensure that belt 36 remains taut throughout the energy storage process, increasing friction between belt 36 and drive pulley 32 and driven pulley 35, thereby improving conversion efficiency. Simultaneously, adjustment rod 2 341 contracts inward under the action of power source 41. When energy storage assembly 2 begins to release kinetic energy, power source 41 is turned off. At this point, the potential energy of return spring 1 331 is less than that of return spring 2 342. As energy storage assembly 2 begins to release kinetic energy, adjustment rod 2 341 slowly extends, increasing the transmission ratio and ensuring output power.

[0056] As an embodiment of the present invention, refer to Figure 2 The axes of the adjusting shaft 34 and the driving shaft 31 are at the same horizontal position.

[0057] In the above embodiment, the energy storage assembly 2 is ensured to be displaced horizontally and not to be subjected to forces in other directions. At the same time, the multiple driven wheels 35 are ensured to be subjected to uniform pressure when in contact with the belt 36, thereby extending the service life.

[0058] As an embodiment of the present invention, refer to Figure 5 A pressing block 343 is provided at the lower end of the second adjusting rod 341 , and a switch 344 is provided at the inner end of the second return spring 342 . The switch 344 is electrically connected to the power supply 41 .

[0059] In the above embodiment, when the adjusting rod 2 341 is retracted to the limit, that is, when the pressing block 343 presses the switch 344, the power supply 41 is cut off, and the adjusting rod 2 341 is no longer powered by the power supply 41 and is in a state where it can move freely. It is pushed outward slowly by the return spring 2 342. At this time, the transmission ratio of the speed change assembly 3 becomes larger, and the rotation speed of the energy storage assembly 2 becomes faster, and it begins to drive the generator 1 to generate electricity.

[0060] Working principle: When external force drives the generator 1 to generate electricity, the generator 1 drives the driving wheel 32 to rotate, and the rotation of the driving wheel 32 drives the driven wheel 35 and the adjusting shaft 34 to rotate, and the adjusting shaft 34 drives the flywheel shaft 21 and the flywheel 22 to rotate to store energy in the form of kinetic energy. During the transmission process, the adjusting rod 2 341 slowly contracts, and the transmission ratio between the driving wheel 32 and the adjusting shaft 34 continues to decrease. At this time, the speed of the flywheel 22 continues to increase, and more energy is stored. When the generator 1 is no longer driven by external force to generate electricity, the speed of the flywheel 22 is greater than the speed of the motor, and the flywheel 22 begins to drive the generator 1 to generate electricity through the adjusting shaft 34, the driving wheel 32 and the belt 36.

[0061] Specifically, the energy storage and release process is as follows: when the external force drives the generator 1 to generate electricity, the generator 1 drives the driving wheel 32 to rotate, the driving wheel 32 drives the driven wheel 35 and the adjusting shaft 34 to rotate through the belt 36, and the adjusting shaft 34 drives the flywheel shaft 21 and the flywheel 22 to rotate. At this time, the power supply 41 provides power to drive the adjusting rod 2 341 to slowly retract. At this time, the transmission ratio between the driving wheel 32 and the adjusting shaft 34 continues to decrease. At this time, the speed of the flywheel 22 continues to increase, and more energy is stored. When the adjusting rod 2 341 is retracted to When the adjusting rod 34 is at the bottom, the pressing block 343 at the inner end of the adjusting rod 341 presses the switch 344. At this time, the power supply 41 no longer supplies energy to the adjusting rod 341. At this time, the adjusting rod 341 will slowly extend under the action of the force of the return spring 342 and the return spring 331. At this time, the transmission ratio between the adjusting shaft 34 and the driving shaft 31 becomes larger, and the speed of the adjusting shaft 34 is greater than the speed of the driving shaft 31. The flywheel 22 begins to supply energy, and the generator 1 is driven to rotate and generate electricity through the adjusting shaft 34, the driving shaft 31 and the belt 36.

[0062] Circuit connected to load stabilization process: power supply 41 supplies power to the adjustment shaft 34, controlling the adjustment shaft 34 to continuously contract. When a new load is connected to the generator 1, the current divided by the current detection resistor 42 decreases, generating a signal. At this time, the signal is transmitted to the relay 43, and the contacts of the relay 43 are closed, connecting the power supply 41 to the circuit. At this moment, the power supply 41 and the generator 1 simultaneously supply power to the load to prevent a large current shock. Because the adjustment rod 2 341 is connected in parallel with the load, the adjustment rod 2 341 is shunted and the power is reduced. At this time, under the influence of centrifugal force, the adjustment rod 2 341 begins to extend. At this time, the transmission ratio is reduced. The energy storage component 2 drives the generator 1 to rotate at this moment, improving the power generation efficiency and ensuring the current stability in the circuit when the load is connected. At this time, the power of the generator 1 is adjusted to meet the power requirement after the load is added. After the circuit is stable, the relay 43 is disconnected, and the power supply 41 again provides energy only to the adjustment rod 2 341. At this time, the adjustment rod 2 341 slowly shortens, and the generator 1 drives the energy storage component 2 to rotate and continue to store energy.

[0063] Adjustment process when starting energy storage: the sliding rheostat 412 and the adjusting rod 2 341 are connected in series. Adjusting the resistance value of the sliding rheostat 412 can change the power of the adjusting rod 2 341, thereby changing the speed of contraction of the adjusting rod 2 341, and then adjusting the ratio of the amount of electricity used by the generator 1 to power the load and the amount of stored electricity. When the generator 1 is running, the circuit is kept stable while the excess electricity is stored in the energy storage component 2.

[0064] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
