Below with reference to accompanying drawing, the explanation of Zhong mono-step is done to on-off energy storage device of the present utility model.It should be noted that at this, the explanation for following execution mode understands the utility model for helping, but does not form restriction of the present utility model.In addition, if below in described each execution mode of the utility model involved technical characteristic do not form conflict each other and just can be combined with each other.
Present embodiment discloses a kind of on-off energy storage device, for the release energy machine structure storage of potential energy for circuit breaker or switch, be also not only confined to circuit breaker or field of switches, can also be used in other needs manual, electronic while energy storage device in.Described release energy machine structure is generally stage clip or torsion spring in circuit breaker or switch, release energy machine structure can storage elasticity potential energy after being biased, thus when circuit breaker or switch need combined floodgate or separating brake, trigger the potential energy stored by the release of release energy machine structure, reach the object of automatic closing or automatic brake separating.
See Fig. 1, the on-off energy storage device bag Qian of the present embodiment rely on rotate to be the energy storage of described release energy machine structure axle 10, for the Manual drive mechanism 20 that drives described axle 10 to rotate and electric driving mechanism 30, under the setting of Manual drive mechanism 20 ensure that the feelings Saeka of electric driving mechanism 30 fault, circuit breaker or switch still can obtain the potential energy of automatic closing, separating brake.Wherein, on axle 10, interlock arranges gear train 12, and when Manual drive mechanism 20 or electric driving mechanism 30 drive gear set 12, gear train 12 can be with moving axis 10 to rotate forward, and is release energy machine structure storage of potential energy.It should be noted that, the direction of rotation of axle 10 when described forward Die is potential energy mechanism storage of potential energy, and oppositely Die potential energy mechanism discharges the direction that potential energy makes axle 10 rotate.
See Fig. 1, Fig. 7, also wrap Qian first one-way clutch mechanism 50, after Manual drive mechanism 20 or electric driving mechanism 30 energy storage terminate, release energy to enable release energy machine structure, therefore holding torque can not be applied to axle 10, under unused state, the potential energy that release energy machine structure gathers can run off along with recovery deformation, and in the present embodiment, first one-way clutch mechanism 50 is when gear train 12 produces reverse rotation trend, gear train 12 reverse rotation is stoped by locking mode, thus make release energy machine structure not recover deformation, the potential energy of release energy machine structure is stoped to run off, ensure the separating brake of circuit breaker or switch, closing speed, improve separating brake, the sensitivity of closing a floodgate.
The set-up mode of the first one-way clutch mechanism 50 in the present embodiment is described in detail below with reference to Fig. 6:
First one-way clutch mechanism 50 wraps Qian and is arranged on multiple gear teeth on gear train 12 periphery, and non-return portion 40, described non-return portion 40 is when gear train 12 drives the gear teeth to rotate forward, intermittent movement is between multiple described gear teeth, described non-return portion 40, when gear train 12 produces reverse rotation trend, engages the gear teeth of gear train 12 and stops gear train 12 reverse rotation.
Zhong mono-step, Qian fixed axis 43 is wrapped in described non-return portion 40, be arranged on check pawl 41 on fixed axis 43 and provide the ratchet bias piece 42 of the biasing force of being partial to the described gear teeth for described check pawl 41, described check pawl 41 is rotating forward arc sliding wall direction having and mates with described gear teeth streamlined.In actual use, when gear train 12 rotates forward, one end that the biasing force of bias piece 42 makes ratchet 41 have arc sliding wall extend between the described gear teeth, pushes ratchet 41 in pinion rotation process aside, makes ratchet 41 Zhong enter between the next gear teeth; When gear train 12 has the movement tendency of reverse rotation, because the arc sliding wall of described ratchet 41 and the direction of motion of gear train 12 are acute angle, therefore ratchet 41 can be rotated further by blocking teeth wheels 12.
The interlock set-up mode of gear train 12 and axle 10 is described in detail below in conjunction with Fig. 2, Fig. 5:
The mode that gear train 12 and axle 10 interlock are arranged has a variety of, such as: the gear in gear train 12, centered by axle 10, is fixedly installed on the set-up mode on axle 10 by fixed structure; Or gear train 12 is direct and the integrated set-up mode of axle 10; Form the gear teeth again or on axle 10, the set-up mode that gear train 12 and described gear teeth meshing link; And can also be gear train 12 is arranged on axle 10 set-up mode by the 3rd hereinafter described one-way clutch mechanism 70; It can also be the combination in any of above-mentioned set-up mode.The setting of gear train 12 only needs to ensure to be with moving axis 10 to rotate when drive gear set 12, those skilled in the art can according to foregoing description in conjunction with general knowledge known in this field, under the condition met design requirement, the concrete set-up mode that selection gear train 12 and axle 10 link as an alternative, does not repeat one by one at this.
With reference to figure 1, gear train 12 wraps Qian first gear 121 and the second gear 122.
As one preferred embodiment, see Fig. 2, the first gear 121 is shaped on described axle 10.In the embodiment shown in figure 2, the gear on Manual drive mechanism 20 engages with described first gear 121, and moving axis 10 can be with to rotate forward, and is the energy storage of described release energy machine structure.Because the first gear 121 is relative with axle 10 fixing, therefore the first one-way clutch mechanism 50 preferably acts on the first gear 121, thus by the reverse rotation of locking first gear 121, stop axle 10 reverse rotation, to ensure that the potential energy that release energy machine structure stores can not run off.Although do not show in the accompanying drawings, the one as the execution mode shown in Fig. 2 is out of shape, and the first gear 121 can also be meshed with electric driving mechanism 30, and it rotates forward under the drive of electric driving mechanism 30.
As a kind of variant embodiment of the first gear 121, the first gear 121 can also be fixedly installed on axle 10 by syndeton, and such as described syndeton can be threaded or steady pin etc., makes the first gear 121 keep relative with axle 10 and fixes.
The set-up mode of Manual drive mechanism 20 in the present embodiment is described in detail below in conjunction with Fig. 1, Fig. 2:
In the present embodiment, Manual drive mechanism 20 wraps Qian gear shaft 21, the gear end of gear shaft 21 engages with gear train 12, as one preferred embodiment, the gear end of gear shaft 21 engages with the first gear 121, and the axle head of gear shaft 21 is connected with rotary handle 211 by the second one-way clutch mechanism 60.
Particularly, with reference to figure 3,4, second one-way clutch mechanism 60 wraps the axle sleeve 61 that Qian has internal tooth, axle sleeve 61 is set in the axle head of gear shaft 21, gear shaft 21 is that the position that axle sleeve 61 is connected forms a spatial accommodation 64, and described spatial accommodation 64 is the radial passage on gear shaft 21, and two slip ratchets 62 are arranged on the two ends of radial passage, elastic component 63 is arranged between two slip ratchets 62, and the flexible bias pressure of elastic component 63 drives two slip ratchets 62 to engage with the internal tooth of axle sleeve 61.When axle sleeve 61 is rotated counterclockwise under state as shown in Figure 4, slip ratchet 62 by intermittent movement between each internal tooth of axle sleeve 61; When axle sleeve 61 turns clockwise under state as shown in Figure 4, slip ratchet 62 will keep relative with axle sleeve 61 to be fixed, and the ratchet 62 that slides keeps relative with gear shaft 21 and fixes, therefore rotary sleeve 61 can rotate by driven gear axle 21, and Zhong mono-step band moving axis 10 rotates energy storage.
The setting of above-mentioned second one-way clutch mechanism 60, make the on-off energy storage device of the present embodiment adopt Manual drive mechanism Zhong row cutting and Zhong capable energy storage time, rotary handle 211 is allowed to turn round, and axle 10 reversed turning can not be made, particularly, in actual use, staff is when drop-down rotary handle 211, driven gear axle 21 moves, Zhong and moving axis 10 can be with to rotate forward, the capable energy storage of Zhong, after this staff does not continue to exert a force to rotary handle 211, because the second one-way clutch mechanism 60 can allow axle sleeve oppositely to dally relative to the axle head of gear shaft 21, rotary handle 211 in the process of return not to gear shaft 21 transmitting torque, Zhong and moving axis 10 can not be with to reverse.
In addition, the setting of above-mentioned second one-way clutch mechanism 60 can also be played in electric energy-stored process, makes the effect that rotary handle 211 does not rotate, thus electric energy-stored process is not impacted Manual drive mechanism.When introducing electric driving mechanism 30 energy storage below with reference to Fig. 2-4, the state of Manual drive mechanism 20:
In setting Fig. 2, clockwise direction is forward, and namely axle 10 turns clockwise energy storage, is rotated counterclockwise, discharges potential energy.In Fig. 2, electric driving mechanism 30 is that the rotation of driving second gear 122 is with moving axis 10 to rotate forward, in the process that axle 10 rotates forward, the first gear 121 is driven to rotate forward, the reverse rotation now then driven with the gear end of the first gear 121 meshed gears axle 21.Below with reference to the generalized section of the second one-way clutch mechanism 60 shown in Fig. 3, and the perspective view of the second one-way clutch mechanism 60 shown in Fig. 4, when gear shaft 21 reverse rotation, slip ratchet 62 can stretch by pressurized, and the motion of interval is between each internal tooth of axle sleeve 61, thus make gear shaft 21 form idle running relative to rotary handle 211, therefore rotary handle 211 can not action, makes can not have influence on Manual drive mechanism 20 in electric energy-stored process.
Further, the setting of above-mentioned second one-way clutch mechanism 60, slip ratchet 62 can be hidden in the spatial accommodation 64 in gear shaft 21, compared to general one-way clutch structure, second one-way clutch mechanism 60 structure of the present embodiment is more simple, takes up room less, Zhong mono-step reduction means volume.Because the structure of the second one-way clutch mechanism 60 is simple, small volume, be therefore applicable to be arranged on limited space but in the not high mechanism of required precision.Obvious second one-way clutch mechanism 60 can also select other forms of clutch, does not repeat at this.
As a kind of variant embodiment of above-mentioned second one-way clutch mechanism 60, described slip ratchet 62 can also be set to three, four or more; And, the direction of slip ratchet 62 is also not limited only to extending radially shown in Fig. 4, it can also be oblique stretches out in a certain angle with radial direction, and what only need to ensure is that slip ratchet 62 can stretch between the internal tooth of axle sleeve 61 under the effect of elastic component 63.
With reference to figure 1, the free end of the rotary handle 211 in the present embodiment is connected with return unit 212 (in this case extension spring), the other end of return unit 212 is fixedly connected on fixed position, such staff can pendulum model pull described rotary handle 211, return unit 212 drives described rotary handle 211 to reset, and in reseting procedure, due to the setting of the second one-way clutch mechanism 60, rotary handle 211 is idle running relative to gear shaft 21.
In actual use, the on-off energy storage device often mounted higher position on utility poles of the present embodiment, staff needed to climb up electric pole around single direction driving rotary handle 211 in the past, could use Manual drive mechanism 20.Length as rotary handle 211 is shorter, need in staff's rotary course apply moment can be very large; Length as rotary handle 211 is longer, and staff has then been difficult to the spinning movement of whole circumference, therefore very large in the difficulty of the aerial manual energy storage of height.
With reference to figure 1,2, in the on-off energy storage device of the present embodiment, staff can be hooked on rotary handle 211 by instrument, rotary handle 211 is pulled by pendulum model on ground, complete manual energy storage action, effectively reduce the labour intensity of staff, also safer compared to existing Manual stored energy organization; Secondly, when slip ratchet 62 resets under return unit 212 acts on, because its intermittent movement is between the internal tooth of axle sleeve 61, therefore can give staff's vibrational feedback on ground, staff is known, and whether manual energy storage is successful.
The set-up mode of electric driving mechanism 30 in the present embodiment is described in detail below in conjunction with Fig. 2, Fig. 5, Fig. 6:
In shown in Fig. 5 preferred embodiment, described electric driving mechanism 30 wraps Qian output motor 31 and drives the gear drive 32 rotated by described output motor 31, described gear drive 32 engages with the second gear 122, rotate to be with moving axis 10, the output shaft driven gear transmission mechanism 32 of output motor 31 rotates, gear drive 32 engages with the second gear 122 again, thus band moving axis 10 rotates, and is release energy machine structure storage of potential energy.As the replaceable execution mode of one, output motor 31 can straight forming engages with the second gear 122 on its output shaft the gear teeth, thus band moving axis 10 rotates.
Zhong mono-step, is also provided with the 3rd one-way clutch mechanism 70 between the second gear 122 and described axle 11, and to enable the second gear 122 when rotating forward to axle 10 transmitting torque, band moving axis 10 rotates; During the second gear 122 reverse rotation, relative axle 10 dallies, can not transmitting torque.Because the 3rd one-way clutch mechanism 70 is for connecting axle 10 and the second gear 122, it more focuses on the transmission of moment of torsion compared to the second one-way clutch mechanism 60, and therefore the 3rd one-way clutch mechanism 70 selects the roller type one way clutch different with the second one-way clutch mechanism 60.Particularly, see Fig. 2, the chute 71 that its bag Qian interval is molded over described second gear 122 inner ring, the roller bias piece 73 being arranged on the roller 72 in described chute 71 and acting on described roller 72, roller 72 number is generally 6-8.In the course of work, if the second gear 122 rotates along the counter clockwise direction shown in Fig. 2 relative to axle 10, so, roller 72 just moves and Compress Spring to large end in the chute 71 with cam profile.At this moment, one-way clutch there will not be locking phenomenon, and allows outer ring rotating; Otherwise if the second gear 122 rotates along the clockwise direction shown in Fig. 2 relative to axle 10, the second gear 122 and 10, axle can be locked, that is, reverse the second gear 122 clockwise and moving axis 10 can be with to rotate, complete electric energy-stored process.
It should be noted that, gear drive 32 preferably uses multi-stage speed-reducing gear train, thus the high speed torque realizing output motor 31 output can be converted to low speed torque, thus makes the thermal energy storage process of electric driving mechanism 30 more steady.
The on-off energy storage device of the present embodiment also wraps Qian casing 80, the agent structure of casing 80 is a vertical mounting panel, described Manual drive mechanism 20 and described axle 10 homonymy are arranged on described casing 80, drive motors 31 in described electric driving mechanism 30 is arranged on the opposite side of described casing 50, and the output shaft of drive motors 31 is connected on gear drive 32 through described casing 80.The benefit of such setting is, Manual drive mechanism 20, electric driving mechanism 30 and casing 80 can be arranged on same installed surface, makes benchmark unique, is convenient to install location.Also ensure that the structure of the on-off energy storage device of the present embodiment is comparatively compact simultaneously, contribute to the miniaturization of lifting means, reduce the installing space of hold facility.
Particularly, one end of described axle 10 is fixedly mounted on casing 80; Being arranged at of described check pawl 41 pivotable is molded on casing 50 on fixed axis 43, and described fixed axis 43 stretches out in the same way with described axle 10; Described ratchet bias piece 42 is for being set in the torsion spring on described fixed axis 43.
In addition, as shown in Figure 2, the on-off energy storage device of the present embodiment also wraps the shell of the coated Manual drive mechanism 20 of Qian and electric driving mechanism 30, and it does not damage by environmental factor mainly for the protection of equipment.
Obviously, above-described embodiment is only for clearly example being described, the restriction not to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And thus the apparent change of extending out or variation be still among the protection range that the utility model creates.
