Description
Technical field
The utility model relates to a kind of novel switched cabinet valve opener, and it is applicable to the air insulation metal enclosed switchgear.
Background technology
At present, the valve opener of domestic 35KV air insulation metal enclosed switchgear adopts the kind of drive of steel cable or chain mostly.All there is the fastening difficulty of assembling in this dual mode, and valve opening process running status is not steady.Therefore, the valve plate obscission in use very likely occurs, also can further cause the generation of phase fault accident under the serious situation.
The utility model content
The utility model is to provide a kind of novel switched cabinet valve opener, and it is applicable to the air insulation metal enclosed switchgear, has assembling simply, and unlatching is flexible, steady, and operation is central safe and reliable.
The technical scheme that the utility model adopted is:
A kind of novel switched cabinet valve opener comprises linkage, guide post and power assistant spring, and described linkage is provided with and promotes connecting rod, intermediate connecting rod and tail end connecting rod; An end that promotes connecting rod is connected with the intermediate connecting rod axle, and the other end is arranged on the fixed support; The other end of intermediate connecting rod is connected on the body of rod of tail end connecting rod; Tail end connecting rod one end be installed in and can be connected along the valve baffle plate that guide post slides up and down, the other end is a free end; Power assistant spring one end is loaded on the body of rod in the outside of tail end connecting rod and intermediate draw bar joint, and the other end is fixed on the side cabinet.
Above-mentioned intermediate connecting rod is detachable the connection with tail end connecting rod, and the body of rod of connecting rod is provided with a plurality of connecting parts that can supply intermediate connecting rod to select endways.
The free end of above-mentioned end connecting rod is provided with a movable pulley.
The said fixing support also is equipped with locking device.
Above-mentioned locking device is provided with latching member and extension spring, one end of latching member is fixed on the locking device, and the other end is provided with a latch hook, and another latch hook that uses that matches with it is fixed on the end that promotes extension bar, one end of extension spring is fixed on the latching member, and the other end is fixed on the locking device.
The utility model advantage: the valve kind of drive adopts linkage, stable drive, reliable, assembling and easy row easy to adjust; Locking is reliable, and when guaranteeing that handcart is removed, valve can not arbitrarily be opened; Power assistant spring adopts push-type gas spring, can guarantee that valve plate is still in optional position in the stroke, convenient maintenance; In service safe and reliable, stopped the possibility that valve plate in service comes off.
Description of drawings
Fig. 1 is the structural principle schematic diagram of a kind of execution mode of the utility model.
Fig. 2 is the structure principle chart of the locking device in Fig. 1 execution mode, shows opening.
Fig. 3 is the structure principle chart of the locking device in Fig. 1 execution mode, shows blocking.
Below in conjunction with accompanying drawing the utility model is described:
Embodiment
Referring to accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, a kind of novel switched cabinet valve opener, comprise linkage, guide post 1 and power assistant spring 2, described linkage is provided with and promotes connecting rod 3, intermediate connecting rod 4 and tail end connecting rod 5, an end that promotes connecting rod 3 is connected with 4 of intermediate connecting rods, and the other end is arranged on the fixed support; The other end of intermediate connecting rod 4 is connected on the body of rod of tail end connecting rod 5; The centre connects 4 bars and is detachable the connection with tail end connecting rod 5, and the body of rod of connecting rod 5 is provided with a plurality of connecting parts that can supply intermediate connecting rod 4 to select endways.Guide post 1 is installed a valve baffle plate 7, and it can slide up and down along guide post 1, and tail end connecting rod 5 one ends are connected with valve baffle plate 7, and the other end is equipped with movable pulley 6; Power assistant spring 2 one ends are loaded on the outside body of rod that tail end connecting rod 5 and intermediate draw bar 4 be linked, and the other end is fixed on the side cabinet, and power assistant spring 2 guarantees that valve plates can be still in optional position in the stroke, convenient maintenance.Fixed support is equipped with locking device 8, locking device is provided with latching member 81 and extension spring 82, latching member 81 is fixed on the locking device 8, one end of latching member 81 is provided with a latch hook, and another latch hook that uses that matches with it is fixed on the end that promotes extension bar 3, and an end of extension spring 82 is fixed on the latching member 81, the other end is fixed on the locking device 8, locking is reliable, and when guaranteeing that handcart is removed, valve can not arbitrarily be opened.Handcart is in progradation, promoting latching member 81 earlier rotates, the latch hook that makes the latch hook of latching member 81 and promote connecting rod 3 is thrown off, and 82 moments of extension spring are in extended state, realize release, promote the driving shaft on the connecting rod 3 again, promote connecting rod 3 and upwards rotate, range is 45 °, by the transmission of linkage, drive valve baffle plate 7 and upwards slide along guide post 1, valve is opened; Handcart is in withdrawing from process, promoting latching member 81 earlier rotates, the latch hook of latching member 81 and the latch hook of promotion connecting rod 3 are buckled extremely mutually, extension spring 82 resets by spring force, forms locking, drives the driving shaft that promotes on the connecting rod 3 again and rotates, driving promotion connecting rod 3 also rotates, by the transmission of linkage, to lower slider, close by the realization valve along guide post 1 for drive valve baffle plate 7.After handcart was released, valve entered blocking, can not arbitrarily open.
This valve arrangement is widely used, by the length of adjusting connecting rod, and the connecting rod radius, the 1000mm that the valve stroke can be enlarged.The selection of power assistant spring will be adjusted according to the weight and the movement travel of valve plate.In valve weight is 10kg, and when stroke is 500mm, but selection pressure is 12kg, and compression travel is the stage clip of 255mm.
