Technical field
The utility model relate in a kind of power transmission and distribution industry in be pressed into the valve arrangement of cover switchgear-armored withdraw type metal enclosed switch cabinet, especially a kind of valve arrangement with differential concatenation slider-crank mechanism.
Background technology
Be pressed into cover switchgear-armored withdraw type metal enclosed switch cabinet in the power transmission and distribution industry, cabinet, current transformer, copper busbar, cable and a cabinet door etc. by handcart chamber, bus-bar room, breaker chamber, cable vault and annex chamber constitute, because circuit breaker will be pulled out to test position from the service position sometimes, afterwards also will from test position to the service position shake into, breaker chamber is provided with automatic valve.For reducing the stroke of valve, valve generally is designed to valve up and down, the vertical guide set up of valve and the right and left symmetry constitutes slide block guide rail mechanism up and down, make that valve can slide up and down up and down, the valve design should make it be controlled by the turnover of circuit breaker and close automatically or open, also promptly should make when circuit breaker when the service position is pulled out to test position, the automatic up-downgoing of valve is opened up and down, otherwise, when circuit breaker shake to the service position from test position fashionable, automatic down up the closing of valve up and down.
The valve that generally adopts on the existing 40.5kV armored withdraw type metal enclosed switch cabinet all is the roller shutter type opening and closing structure, when circuit breaker shakes fashionable from test position to the service position, following valve can press down simultaneously by left and right sides valve pressure arm and open, and last valve then is to be connected with following pressure arm by braking rope and top sheave machine mechanism to be achieved synchronous backward motion (promptly upwards opening).
Because not high easy wearing and tearing of braking rope mechanical performance and be difficult for realizing, this design security reliability is lower, if braking rope is just in case sending electricity work to interrupt, last valve drops on the last contact arm of circuit breaker, form the three-phase shortcircuit accident, will bring unnecessary loss to the power supply user.
The utility model content
At the deficiencies in the prior art part, technical problem to be solved in the utility model just provides a kind of security reliability height, can guarantee to satisfy the valve arrangement of the armored withdraw type metal enclosed switch cabinet of degree of protection requirement in the GB.
Solve the problems of the technologies described above, the utility model can be realized by following technical scheme:
A kind of valve arrangement of armored withdraw type metal enclosed switch cabinet, comprise the vertical guide formation slide block guide rail mechanism that sets up with the right and left symmetry, the valve up and down that can slide up and down, it is characterized in that: be arranged with crank connecting link on the switch cubicle sidewall of described valve both sides down, the other end of crank connecting link is hinged with following valve, constitutes slider-crank mechanism; Be arranged with rocker-arm link mechanism on the switch cubicle sidewall of described upward valve both sides, the other end of rocker-arm link and last valve are hinged, constitute the rocking arm slide block mechanism; The other end of described rocking arm is hinged by returnconnecting rod and following valve again, promptly finally constitutes the differential concatenation slider-crank mechanism.
Described crank is provided with the back-moving spring of closing valve.
Described up and down valve both sides are individually fixed on the slide block, and slide block slides on the vertical guide rod as guide rail.
Described crank is controlled by the turnover of circuit breaker and rotates.
Stretch out a pressure arm to circuit breaker on the described crank and extract the track below that advances out, when circuit breaker is extracted out, can push pressure arm and rotate, otherwise pressure arm is together with crank reverse rotation under the pulling force of back-moving spring together with crank.
Compared with prior art, the beneficial effects of the utility model are: because this cover valve arrangement all is to make mechanical connection with connecting rod, on reliability and security performance, be guaranteed, thus the reliability service of the feed electricity that effectively ensures.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the schematic perspective view that the valve arrangement with differential concatenation slider-crank mechanism of the utility model embodiment is in closure state;
Fig. 2 is the principle schematic of Fig. 1 embodiment.
Among the figure: 1, crank axle bed, 2, crank, 21-pressure arm, 3, back-moving spring, 4, crank connecting link, 5, lower guide rod, 6, sliding block, 7, returnconnecting rod, 8, rocking arm, 9, following valve, 10, rocker shaft bed, 11, rocker-arm link, 12, go up valve, 13, top shoe, 14, top guide bar, 15, the guide rod fixed support.
Embodiment
As depicted in figs. 1 and 2, valve arrangement embodiment of the present utility model, comprise the vertical guide formation slide block guide rail mechanism that sets up with the right and left symmetry, the upper and lower valve 12,9 that can slide up and down, upper and lower valve 12,9 both sides of this example are individually fixed on the upper and lower slide block 13,6, on the upper and lower vertical guide rod 14,5 as guide rail, upper and lower vertical guide rod 14,5 is fixed on again on the guide rod fixed support 15 upper and lower slide block 13,6 sliding sleeves respectively.
Certainly; also can be upper and lower slide block 13,6 directly just up and down valve as the slide block of slide block guide rail mechanism; valve directly is stuck in the guide rail with groove and slides up and down up and down; or going up lower guide rod also can be integrated; this all is that those skilled in the art can expect; all fall into the protection range of this patent, this does not state in addition.
On the switch cubicle sidewall of following valve 9 both sides, be arranged with toggle, one end of crank 2 is hinged on the switch cubicle sidewall by crank axle bed 1, also be that crank 2 can rotate around crank axle bed 1, one end of crank 2 and an end of crank connecting link 4 are hinged, the other end of crank connecting link 4 is then hinged with following valve 9, so constitutes crank connecting rod sliding block mechanism; Be provided with the back-moving spring 3 of closing valve between switch cubicle sidewall and the crank, stretch out a pressure arm 21 (both are integrally welded structure) to circuit breaker on the crank 2 and extract the track below that advances out, can push pressure arm when circuit breaker is extracted out rotates around crank axle bed 1 together with crank, otherwise pressure arm is together with crank reverse rotation under the pulling force of back-moving spring 3, and promptly crank 2 is controlled by the turnover of circuit breaker and rotates.
On the switch cubicle sidewall of last valve 12 both sides, be arranged with rocker-arm link mechanism; rocking arm 8 is hinged on the switch cubicle sidewall by rocker shaft bed 10 from central; also be that rocking arm 8 can rotate around rocker shaft bed 10; end of rocking arm 8 and an end of rocker-arm link 11 are hinged; the other end of rocker-arm link 11 is then hinged with last valve 12, so constitutes the rocker-arm link slide block mechanism.
