Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
With shown in Figure 4, a kind of GIS breaker mechanism closes a floodgate and keeps structure the embodiment of the utility model with reference to figure 3, comprises connecting lever 1, closing a floodgate keeps sincere sub 2, separating brake sincere sub 3 and switching winding 7; Also comprise separating brake semiaxis 4, separating brake dropout plate 5, torsion spring 6, first roller 8, second roller 9, extension spring 10, fastener 11 and torsion spring 12, wherein, described combined floodgate keeps sincere sub 2 to be installed on the connecting lever 1 by bearing pin; Described first roller 8, second roller 9 and extension spring 10 are parts of fastener 11, and described fastener 11 is arranged between connecting lever 1 and the separating brake sincere sub 3, and a side of described separating brake sincere sub 3 has fastener 11; Opposite side is provided with separating brake semiaxis 4, is socketed with torsion spring 6 outside the described separating brake semiaxis 4, and the side of described separating brake semiaxis 4 is connected with separating brake dropout plate 5 by bolt; Described switching winding 7 is installed in separating brake dropout plate 5 sides; After combined floodgate put in place, second roller 9 on the fastener 11 withstood and close a floodgate to keep sincere sub 2, simultaneously; Separating brake sincere sub 3 pushes up on the separating brake semiaxis 4, and torsion spring 12 makes the separating brake semiaxis closed.
Among them, the crank arm an aluminum bracket fixed to the institution where the closing maintaining Zhi sub 2 mounted on one end of the crank arm, in the closing maintaining Zhi sub 2 is provided with a top column, when the switch is in place, the co- maintaining the detent gate 2 through the top of the second column top roller 9; fastener structure 11, the first roller 8 is disposed in an upper end 11 of the fastener, said second roller 9 is disposed in the central portion side of the fastener 11 , one end of the tension spring 10 fixed to the fastener 11, and the other end connected to the outside of the second roller 9; 3 wherein the detent trip Movement
shape, the sub-gate Zhi sub 3 and the torsion spring 12 fixed by the fixing lever At the institutional aluminum shell, and said sub-gate Zhi sub 3 and torsion spring 12 coaxially; said tripping axle 4 is provided with a semicircular notch, the sub-gate Zhi sub 3 Axle 4 with the contact trip surface is circular surface.
The maintenance structure of closing a floodgate is three force structures.Close a floodgate to keep sincere sub 2 to be installed on the connecting lever 1 through bearing pin, connecting lever 1 is fixed in mechanism's aluminum hull support, and combined floodgate spring or sluice separating spring release energy and be with connecting lever 1 to do clockwise direction or motion counterclockwise.Torsion spring 12 is enclosed within outside the separating brake semiaxis 4, and separating brake dropout plate 5 is fixed by bolts on the separating brake semiaxis 4, and switching winding 7 gets the electric separating brake semiaxis 4 of opening, mechanism's separating brake.Separating brake pallet 3 is fixed in mechanism's aluminum hull through fixed lever with torsion spring 6, and the extension spring 10 and second roller 9 all are the parts of fastener 11, and second roller 9 was used for withstanding closing a floodgate and keeps sincere son after mechanism closed a floodgate, and extension spring 10 resets fastener behind mechanism's separating brake.
Operating principle:
The combined floodgate of mechanism keeps motion: after mechanism's combined floodgate spring energy storage, and the closing coil action, mechanism's cam heads on connecting lever 1 and is rotated counterclockwise, and connecting lever 1 is being with to close a floodgate and is being kept sincere sub 2 motions counterclockwise.After combined floodgate put in place, sluice separating spring had energy, and sluice separating spring releases energy, and connecting lever 1 is being with and close a floodgate is being kept sincere sub 2 to turn clockwise, and fastener 11 is waited in advance under the effect of extension spring 10 that constraint is closed a floodgate and kept sincere sub 2 actions that turn clockwise.Close a floodgate to keep sincere sub 2 to be withstood by second roller 9 of fastener 11, the energy that connecting lever 1 turns clockwise passes to separating brake sincere sub 3 through fastener 11.Separating brake sincere sub 3 turns clockwise and pushes up on the separating brake semiaxis 4, and torsion spring 12 guarantees that the separating brake semiaxis is closed, and connecting lever 1 clockwise power is just restrained like this, and mechanism closes a floodgate and maintains, and closes a floodgate and accomplishes.
The separating brake motion of mechanism: close a floodgate and accomplish, sluice separating spring is energy storage.Switching winding 7 action, propelling coil dropout plate 5 overcomes the torsion of torsion spring 12, separating brake semiaxis 4 turns clockwise, when the breach of separating brake semiaxis 4 rotate to sincere sub 3 arc surfaces of separating brake through the time, closing a floodgate keeps constraint release.The sluice separating spring band connecting lever 1 and is turned clockwise, and separating brake is accomplished.Simultaneously, sincere sub 3, the separating brake semiaxis 4 of separating brake, fastener 11 reset under the effect of torsion spring 6, torsion spring 12, extension spring 10, and closing a floodgate keeps structure to be in closure state, for the back of closing a floodgate keeps preparing next time.
The above execution mode has only been expressed a kind of execution mode of the utility model, but can not therefore be interpreted as the restriction to the utility model scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection range of the utility model.
