Description
Technical Field
The present disclosure relates to clutch mechanisms, and particularly to a clutch mechanism for an energy storage device. In addition, the invention also relates to a gas insulated circuit breaker adopting the clutch mechanism.
Background
Various energy storage devices must cooperate with the clutch mechanism to accumulate energy and release it when needed. These energy storage devices may, for example, utilize a spring to accumulate potential energy and place the clutch mechanism in a bi-directional rotatable state to release energy when energy accumulation is complete.
The existing gas insulated circuit breakers for high-voltage power transmission all adopt an energy storage device and a clutch mechanism matched with the energy storage device, and the clutch mechanism enables the energy storage device to accumulate and store energy in a state that the energy storage device can only rotate in one direction. When the clutch mechanism is in a state of being capable of rotating bidirectionally, the power device is mechanically separated from the energy storage device, so that the energy accumulated in the energy storage device is released, the potential energy stored in the energy storage device is converted into kinetic energy, and the operating mechanism in the gas insulation circuit breaker is pushed to open or close a circuit connected with the gas insulation circuit breaker. One conventional clutch mechanism is in the form of a ratchet mechanism, in which a ratchet wheel and a pawl are engaged with each other, and the ratchet wheel can rotate only in one direction along with the accumulation of energy in a state in which the ratchet wheel can rotate only in one direction, so that the accumulated energy is not lost. When the energy storage device finishes energy accumulation, the pawl and an arc surface on the ratchet wheel realize mechanical separation of the power device and the energy storage device, and release energy when needed.

Detailed Description
In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings. In the drawings, like reference numbers indicate identical or structurally similar elements that perform the same function, and elements having the same structure or function are depicted schematically, or are identified. For the sake of simplicity, only the parts relevant to the present invention are schematically shown in the drawings, and they do not represent the actual structure as a product. "connected" or "fixed" herein means directly connected or fixed, or connected or fixed via a third party.
As shown in fig. 1 to 5, a clutch mechanism for an energy storage device includes a loading gear 25, a driving gear 22, two bearings 23 (e.g., deep groove ball bearings, etc.), and a gear shaft 24 including a gear portion 241 and a clutch portion 242, wherein the loading gear 25 is coaxially connected to the clutch portion 242 through the bearings 23 in a bi-directional rotatable manner, and the driving gear 22 is externally engaged with the gear portion 241. The gear shaft 24 includes five cylindrical bodies 28, five clutch levers 29 and five first elastic members 30 corresponding to the cylindrical bodies 28, and one push rod 21 and one second elastic member 20 located in the cavity of the gear shaft 24, wherein the clutch part 242 has five "V" -shaped stopper grooves 243 corresponding to the cylindrical bodies 28 in the circumferential direction, and the cylindrical bodies 28 are located in the "V" -shaped grooves. It will be understood by those skilled in the art that although the illustrated embodiment employs five cylinders, it is possible to employ fewer or more than five cylinders and corresponding trip lever, first resilient element and limit groove as desired, as long as the number is selected to meet the design requirements. In addition, other shapes of the limiting groove besides the V shape, such as a trapezoidal groove with a slope, can also be adopted. The trip lever 29 movably passes through a wall of the trip portion 242, and one end of the first elastic member 30 is fixed to the trip portion 242 through the hole 33 of the trip portion 242 and the other end presses the trip lever 29. The clutch mechanism may further include five pins 32 corresponding to the first elastic element 30. The pin 32 is located at the clutch portion 242 and is axially installed between both ends of the first elastic member 30 on the side away from the axis of the gear shaft 24, so that the first elastic member 30 is elastically deformed when the clutch lever 29 pushes the cylindrical body 28. Those skilled in the art will appreciate that the pin 32 is not necessary in the case where one end of the first resilient element 30 is non-rotatably secured in the bore 26, but the mounting of the pin 32 is advantageous in enhancing the effect of squeezing the trip lever 29. Those skilled in the art will also appreciate that the first resilient element 30 may be a resilient metal ring, but may also be other known metallic or non-metallic components. The various parameters of the "V" shaped restraint slot 243 may be selected by one skilled in the art based on the design requirements of existing overrunning clutches. In the present invention, the boundary between the gear portion 241 and the clutch portion 242 does not merely mean a boundary between the two, but includes a position close to the boundary. As will be appreciated by those skilled in the art. The terms "axial direction", "radial direction" and "circumferential direction" in the present invention refer to directions of the respective components with respect to the axis of the gear shaft 24 after the clutch mechanism is assembled, and the term "axis" refers to the axis of the gear shaft 24.
The push rod 21 includes an engaging groove 211 and is slidable in the axial direction, wherein the second elastic member 20 engages an end of the push rod 21 and presses the push rod 21. The second elastic element 20 can be fixed in the cavity of the gear shaft 24 by a plug 27, as shown in fig. 4 and 5, or by other not shown stoppers. The driving gear 22 is fixed with a pressing block 26, and the inclined surface 261 of the pressing block 26 can contact the other end of the push rod 21 and push the push rod 21 to slide in the axial direction. When the stored energy is complete, the mass 26 rotates to the position shown in fig. 2 and 4 and pushes the push rod 21. In this process, the push rod 21 slides in the axial direction so that one end of the clutch lever 29 leaves the clutch groove 211 in the radial direction and the other end thereof protrudes into the stopper groove 243, thereby pushing the cylinder 28 into the bottom of the stopper groove 243. The cylinder 28 at the bottom of the stopper groove 243 can be disengaged from mechanical contact with the loading gear 25 in both directions (clockwise and counterclockwise directions) as shown in the sectional view B-B of fig. 4, without being clamped between the loading gear 25 and the gear shaft 24, thereby enabling the loading gear 25 and the gear shaft 24 to be rotated bidirectionally. At this time, the clutch lever 29 presses the first elastic member 30 to be elastically deformed. At the same time, the cylinder 28 presses the third elastic member 31, wherein the third elastic member 31 may be a combination of a spring and a pin (not shown) or one spring as shown in fig. 4 and 5, and one end of the third elastic member 31 is installed in the holes 244 (two holes 244 are shown in fig. 4 and 5, respectively, and one third elastic member 31 corresponds to each hole 244). During this process, the stored energy may undergo a release operation. During the energy release process, the driving gear 22 and the pressing block 26 rotate synchronously, and the driving gear 22 drives the gear shaft 24 to rotate clockwise (as shown in the cross-sectional view B-B of FIG. 4). Since the loading gear 25 is stationary at this point, the cylinder 28 cannot be clamped between the loading gear 25 and the pinion shaft 24, and the pinion shaft 24 will continue to rotate until the entire energy release is complete, eventually causing the operating device to close the circuit.
When the pressing piece 26 fixed on the driving gear 22 rotates at a proper angle, the pressing piece 26 will be disengaged from the push rod 21, at this time, the push rod 21 slides axially to a proper position to be reset under the action of the second elastic element 20, and at the same time, the first elastic element 30 presses the clutch lever 29 radially toward the axis, thereby returning the cylinder 28 to the disengaging groove 211 as shown in the sectional view B-B of fig. 5. In this process, the third elastic member 31 located at the side of the catching groove 243 opposite to the clutch lever 29 pushes the cylinder 28 away from the bottom of the catching groove 243. At this time, if the loading gear 25 is rotated clockwise with respect to the gear shaft 24 about the sectional view B-B in fig. 5, the cylindrical body 28 will be clamped between the drive gear 22 and the gear shaft 24, thereby locking the drive gear 22 and the gear shaft 24 non-rotatably. Those skilled in the art will appreciate that the location at which the press block 26 is secured to the drive gear 22 and its size may be selected as required by design parameters. The clutch mechanism and the gas insulated circuit breaker thereof realize simple, convenient and reliable mechanical separation between the power device and the energy storage device when the energy storage is finished at lower cost. One end of the clutch lever 29 contacting the push rod 21 or one side of the clutch groove 211 contacting the clutch lever 29, or both, has a slope so that the clutch lever 29 can leave or enter the clutch groove 211 when the push rod 21 slides in the axial direction. The ramp surface facilitates relative movement of the clutch lever 29 and the clutch recess 211. Furthermore, the push rod 21 has a guide sleeve 212 between its end in contact with the pressure piece 26 and the gear shaft 24. The guide sleeve facilitates the guidance of the push rod 21. It will also be appreciated by those skilled in the art that the transmission ratio of the driving gear 22 and the gear portion 241 may be selected accordingly according to various practical parameters of the power device, the operation device and the energy storage device, and that the first elastic element 20 is preferably a spring, but may be other elements capable of engaging and compressing the push rod 21. As shown in fig. 6, the pressing piece 26 includes a slope 261 that can contact the push rod 21, thereby facilitating smooth contact between the pressing piece 26 and the push rod 21.
According to one embodiment, not shown, the gas-insulated switchgear of the present invention comprises a power unit, an operating device, an energy storage device, and the above-mentioned clutch mechanism, wherein the loading gear 25 is connected to the power unit, the driving gear 22 is connected to the energy storage device, and the gear shaft 24 is connected to the operating device. When the clutch mechanism is in the locked position shown in fig. 2 and 5 after the energy accumulated by the energy storage device is released, the elastic member 20 engages one end of the push rod 21 and presses the push rod 21, and the push rod 21 abuts against the inner wall of the cavity of the gear shaft 24. In the process, the clutch lever 29 slides in the axial direction in the radial direction, and the loading gear 25 and the gear shaft 24 can rotate only in one direction. At this time, the rotation of the loading gear 25 using a power source such as an electric motor will rotate the gear shaft 24 synchronously, thereby converting kinetic energy into potential energy in the energy storage device connected to the driving gear 22, wherein the design of unidirectional rotation only ensures that the stored energy is not released during the loading process. At the same time, the drive gear 22 will also rotate synchronously due to the meshing engagement with the gear portion 241, and the pressure piece 26 will also rotate synchronously due to the fixation to the drive gear 22.
It should be understood that although the present description has been described in terms of various embodiments, not every embodiment includes only a single embodiment, and such description is for clarity purposes only, and those skilled in the art will recognize that the embodiments described herein can be combined as a whole to form other embodiments as would be understood by those skilled in the art.
"exemplary" means "serving as an example, instance, or illustration" herein, and any illustration, embodiment, or steps described as "exemplary" herein should not be construed as a preferred or advantageous alternative.
The above description is only an exemplary embodiment of the present invention, and is not intended to limit the scope of the present invention. Any equivalent alterations, modifications and combinations can be made by those skilled in the art without departing from the spirit and principles of the invention.
