Embodiment
As shown in Figure 1, the present invention includes valve blocking device 2 and opening device 1.As shown in Figure 4, valve blocking device 2 comprises gear 3, tooth bar 4, tooth bar 11 and base 5, and base is respectively arranged with chute 6 in both sides about in the of 5, slidely connects tooth bar 4 in the chute 6, gear 3 is located in the middle of the tooth bar 4,11, and tooth bar 4,11 is arranged about 3 pairs of gears.As shown in Figure 5, be connected with valve 7 on the tooth bar 4, be connected with valve 12 on the tooth bar 11, gear 3 and tooth bar 4,11 engaged transmission.Along with relatively moving of tooth bar 4,11, valve 7,12 also opens or closes thereupon.
As shown in Figure 2, opening device 1 inside is hollow.Opening device 1 comprises outer sleeve 13 and inner sleeve 14, adopts between outer sleeve 13 and the inner sleeve 14 to be slidingly connected.Adopt spline to connect between outer sleeve 13, the inner sleeve 14, outer sleeve 13 on the left end cylindrical of inwall, inner sleeve 14 correspondence be provided with a pair of or a pair of more than the spline 16 and the card article 17 of (shown in Fig. 3 being 4 pairs), just can drive outer sleeve 13 when rotating inner sleeve 14 so simultaneously and rotate thereupon.In addition, be provided with step, the two disengagement when preventing to spur inner sleeve 14 left in outer sleeve 13 right-hand member ends and inner sleeve 14 left end end correspondences.Be provided with induction electroscope 10 in the inner sleeve 14, inner sleeve 14 right-hand members are handle 15, and electroscope 10 is sealed in inner sleeve 14 the insides.Because the space that valve blocking device 2 is opened is still sealed by handle 15, so switch cubicle is in sealing state all the time.
Shown in Fig. 1,3, on gear 3 lateral surfaces, be provided with two grooves 8 (present embodiment employing hole).The end of opening device 1 is provided with and groove 8 corresponding two projectioies 9.The quantity of groove 8 can be made as two or more as required, and the quantity of respective bump 9 also is two or more.
As shown in Figure 6, base 2 right flanks are provided with draw-in groove 20, and draw-in groove 20 is circular, and draw-in groove 20 right flanks respectively are provided with a vee 19 up and down, and correspondence is provided with the fixture block 18 similar to breach 19 shapes at outer sleeve 13.The turning radius size of fixture block 18 is between draw-in groove 20 circle and draw-in groove 20 radius of a circle size in the outer part in the inner part, and when fixture block 18 rotated in draw-in groove 20, outer sleeve 13 not only rotated flexibly but also can not throw off with base 2 like this.
The position of groove 8 should partly or entirely be arranged on breach 19 places.When valve 7,12 is closed, if there is the people not use opening device 1 to go to open, even use object can insert groove 8 but can not transmitting gear 3, also just valve 7,12 can not be opened, thereby avoid causing danger.
When fixture block 18 when draw-in groove 20 rotates, it also is feasible adopting a pair of groove 8 and projection 9.There is block the appropriate location in draw-in groove 20 in addition, can be withstood by block after fixture block 18 turns an angle like this, and the people is more convenient to operate.
During use, select suitable position perforate cashier's office in a shop at high-voltage switch gear earlier, valve is installed then, the present invention is fixed on high-voltage switch gear cashier's office in a shop, the sealing of fixing back.
When the needs electrical verification, fixture block 18 alignment notch 19 are put into, then projection 9 is inserted in the corresponding groove 8, about 90 degree that turn clockwise then, under the rack-and-pinion effect, valve 7,12 is opened thereupon relatively.Fixture block 18 is stuck in the draw-in groove 20, and this moment, outer sleeve 13 was locked with base 5.Promote the handle 15 on the inner sleeve 14 then forward, electroscope 10 is contacted with electrified body, send signal by electroscope 10 and judge whether charged.Behind the electrical verification EO, inner sleeve 14 is pulled back, electroscope 10 is withdrawed from.And then be rotated counterclockwise about 90 degree, valve 7,12 is closed close the border.Take off opening device 1 at last.
When measuring, the present invention makes switch cubicle be in sealing state always, has avoided opening the switch cubicle that may have high-tension electricity and the danger that brings like this.In addition, the present invention can also be installed the sound prompt function of unblanking additional, further avoids occurring erroneous judgement.Need to prove at last, also can cancel spline 16 and card article 17, single use outer sleeve 13 rotations also can be rotated by driven gear 3 during rotation.Approximate variation so also drops within protection scope of the present invention.
