Abstract
Description
Technical Field
[0001] The utility model relates to the field of power output devices, in particular to a superimposed push-torque power output device. Background Art
[0002] The rotor of the generator is driven by an external force (such as a turbine, steam turbine, diesel engine, etc.) to rotate in the stator, cutting the magnetic lines of force, thereby generating an induced potential, which is led out through the wiring terminals and connected to the circuit to generate current. For large generators, a large drive device is needed to generate high-torque power to maintain the rotation of the rotor. Due to the effect of inertia, the torque required for the rotor startup phase and the normal operation phase is different. A low-torque drive device is difficult to drive the rotor to start and enter the normal operation phase. When the rotor is operating normally, a high-torque drive device needs to consume more energy to maintain the operation of the drive device, resulting in a waste of resources. In addition, the current drive device has a complex structure and a large size. Utility Model Content

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0028] Superimposed push-torque power output device, including
[0029] The energy storage device 1 comprises a main shaft 11;
[0030] A starting device 2, comprising at least two groups of starting mechanisms 21, wherein the two groups of starting mechanisms 21 relay to drive the spindle 11 to rotate, so as to increase the rotation speed of the spindle 11;
[0031] The thrust device 3 includes at least two sets of thrust mechanisms 31 . The thrust mechanisms 31 are used to drive the main shaft 11 to rotate so as to maintain the rotation speed of the main shaft 11 .
[0032] The utility model provides a superimposed push-torque power output device. When starting, the starting device outputs power, one starting mechanism pushes the main shaft to accelerate from rest, and the other starting mechanism relays to push the main shaft, so that the main shaft continues to accelerate on the basis of the current speed. The two starting mechanisms act on the main shaft alternately, and then the thrust device intervenes, and the two thrust mechanisms act on the main shaft alternately to maintain the speed of the main shaft, thereby achieving energy saving. The main shaft accelerates to a preset speed range, and the main shaft is maintained within the preset speed range.
[0033] Further, as a preferred embodiment of the present invention but not limiting, the main shaft 11 is provided with a plurality of one-way bearings 12, a plurality of groups of the starting mechanisms 21 are arranged one-to-one corresponding to the one-way bearings 12, and at least two groups of the starting mechanisms 21 relay to drive the main shaft 11 to rotate; the starting mechanism 21 includes a starting power source 22;
[0034] The starting power source 22 performs a reciprocating motion of extending and retracting. When the starting power source 22 extends, the one-way bearing 12 drives the main shaft 11 to rotate synchronously. When the starting power source 22 retracts, the one-way bearing 12 rotates relative to the main shaft 11. When the extending speed of the starting power source is greater than the rotating speed of the main shaft, the main shaft is driven to rotate. When the extending speed of the starting power source is less than the rotating speed of the main shaft, the two do not interfere with each other.
[0035] Further, as a preferred embodiment of the present invention but not limiting, the starting mechanism 21 further includes a connecting assembly 23 disposed between the output end of the starting power source 22 and the one-way bearing 12, and the connecting assembly 23 is used to convert the linear motion of the starting power source 22 into a reciprocating motion that drives the one-way bearing 12 to rotate back and forth. The connecting assembly can use a crank slider mechanism, a gear connecting rod mechanism, a swing connecting rod mechanism, a slider-connecting rod mechanism, etc. to achieve motion conversion.
[0036] Further, as a preferred embodiment of the present invention but not limiting, the connecting assembly 23 includes a swing arm 231, one end of the swing arm 231 is hinged to the one-way bearing 12, and the other end is hinged to the output end of the starting power source 22. When the starting power source is extended, it pushes the swing arm, and the swing arm rotates around the one-way bearing, thereby driving the main shaft to rotate.
[0037] Furthermore, as a preferred embodiment of the present invention but not limiting, it further comprises a base frame 6, and an articulated seat 7 for swinging of the base frame 6 and the starting power source 22 is provided between the base frame 6 and the starting power source 22. The articulated seat supports the swinging of the starting power source.
[0038] Further, as a preferred embodiment of the present invention but not a limitation, the one-way bearing 12 rotates back and forth by 120°. The one-way bearing rotates by 360° in total, which is divided into three parts. The first part is driven by a starting power source for 120°, the second part is driven by another starting power source for 120°, and the third part can temporarily stop being stressed. The gaps between the three parts are driven by the two starting power sources in turn, which can effectively prevent metal fatigue.
[0039] Further, as a preferred embodiment of the present invention but not limiting, a counterweight wheel 14 is provided at both ends of the main shaft 11. In this embodiment, the weight of the counterweight wheel is 2 tons, totaling 4 tons. The starting device needs 1-2 hours to increase the speed of the counterweight wheel, that is, the main shaft to a preset speed range, so that the counterweight wheel has inertia. The weight range of the counterweight wheel is 0-20000kg.
[0040] Further, as a preferred embodiment of the present invention but not limiting, the one-way bearing 12 includes a first half bearing 121 and a second half bearing 122 for fitting on the main shaft 11, and a locking block 123 for locking the first half bearing 121 and the second half bearing 122. The main shaft is relatively long, and with the current machining accuracy, it is difficult for an ordinary one-way bearing to be fitted into a desired position, so the first half bearing and the second half bearing need to be fitted.
[0041] Further, as a preferred embodiment of the present invention but not limiting, the transmission gear 13 includes a first half gear 131 and a second half gear 132 for fitting on the main shaft 11, and a locking block 123 for locking the first half gear 131 and the second half gear 132. The main shaft is relatively long, and with the current machining accuracy, it is difficult for an ordinary transmission gear to fit into a desired position, so it is necessary to fit the first half gear and the second half gear.
[0042] Further, as a preferred implementation of the present solution but not limiting, the starting power source 22 is an electric push cylinder, a hydraulic push cylinder, or a pneumatic push cylinder.
[0043] Further, as a preferred implementation of the present solution but not limiting, the start interval time difference between the two start mechanisms 21 is less than or equal to the extension time of the start mechanism 21. This can prevent the spindle from losing speed.
[0044] Further, as a preferred embodiment of the present invention but not limiting, the extension stroke L of the starting power source 22 is 0-2000 mm, the extension speed S is 0-2500 mm / s, the extension time T=L / S, and the load is 0-20000 kg.
[0045] Further, as a preferred implementation of the present solution but not a limitation, the extension stroke of the starting power source 22 is 300 mm, the extension speed is 500 mm / s, and the extension time is 0.6 s.
[0046] Further, as a preferred embodiment of the present invention but not limiting, the main shaft 11 is provided with a plurality of transmission gears 13, and the thrust mechanism 31 includes a thrust power source 32; the thrust power source 32 performs reciprocating motion to intermittently drive the main shaft 11 to rotate;
[0047] Multiple sets of the thrust mechanisms 31 are arranged one by one with the transmission gears 13, and at least two sets of the thrust mechanisms 31 relay to drive the main shaft 11 to rotate. The thrust device utilizes the inertia of the main shaft and utilizes the two thrust mechanisms to act on the main shaft alternately, so that a thrust power source with a relatively small power can be used, thereby achieving the effect of improving work efficiency and saving energy.
[0048] Further, as a preferred embodiment of the present invention but not limiting, a rack 33 is provided on the output end of the thrust power source 32, and the thrust mechanism 31 includes a transmission assembly 34 provided between the transmission gear 13 and the rack 33.

Since the main shaft has a rotation speed, when the main shaft has inertia, the transmission assembly reduces the torque of the thrust power source and increases the rotation speed, so as to maintain the current rotation speed of the main shaft. The function of the transmission assembly is similar to that of a reduction box and a pulley mechanism, which achieves a labor-saving effect, so that a thrust power source with lower power can be used to achieve an energy-saving effect.

When the rack is reciprocating, the rack extends to drive the main shaft to rotate, and when the rack is retracted, it conflicts with the rotation direction of the main shaft, so a one-way gear is used.
[0051] Further, as a preferred implementation of this solution but not a limitation, the first gear 341 is a one-way gear, and when the rack 33 is extended, the first gear 341 drives the second gear 342 to rotate synchronously, and when the rack 33 is retracted, the first gear 341 rotates relative to the second gear 342. It is a preferred mode of this embodiment that the first gear is a one-way gear.
[0052] Further, as a preferred implementation of the present solution but not a limitation, a gear ratio between the second gear 342 and the third gear 343 is greater than one, and a gear ratio between the fourth gear 344 and the transmission gear 13 is greater than one.

[0055] Further, as a preferred implementation mode of the present invention but not limiting, the start-up interval time difference between the two thrust mechanisms 31 is less than or equal to the push-out time of the thrust mechanisms 31. Before one thrust mechanism withdraws its force, the other thrust mechanism intervenes, so that the kinetic energy loss is minimized, and the two thrust mechanisms work simultaneously for a short time, thereby avoiding energy waste.
[0056] Further, as a preferred implementation of this solution but not limiting, the push stroke X of the thrust power source 32 is 0-2000 mm, the push speed Y is 0-2500 mm / s, the push time Z=X / Y, and the load is 0-20000 kg.

[0061] Furthermore, as a preferred implementation mode of the present invention but not a limitation, the energy storage device 1 also includes a counterweight wheel 14 arranged on the main shaft 11, and the starting device 2 drives the counterweight wheel 14 to rotate through the main shaft 11 so that the counterweight wheel 14 generates inertia, and the thrust device 3 is used to enable the counterweight wheel 14 to maintain the current inertia.
[0062] Furthermore, as a preferred implementation manner of the present solution but not limiting, it further includes a generator 4 connected to the main shaft 11, and the main shaft 11 is used to drive the generator 4 to generate electricity.
