Lock dog has coupled key D1, D2, D3, D4, D5, D6, such as, the people on manhole door M1 successively
The first manhole door lock block of hole door lock BDL2 mates with key C1, and the second manhole door lock dog has coupled key
Spoon D1, only when key C1, D1 are inserted simultaneously into manhole door lock BDL2, manhole door M1 just can open,
Other five fans manhole door in like manner, repeats the most one by one at this.
Fig. 2 shows the locking bolt lock BBL1 that Article 1 inlet wire of the present invention uses, and it includes telescopic lock
Tongue S1, key A1 and dead bolt S1 link, and key A1 inserts lock core and rotates, and dead bolt S1 retracts,
Key A1 rotates and extracts then dead bolt S1 ejection, thus corresponding by dead bolt S1 flexible insertion earthing switch blade
Shrinkage pool in thus control the lock-out state of earthing switch blade.Also have anti-on the lock core of this locking bolt lock BBL1
Dirt lid G1.
Fig. 3 shows the separating brake "on" position comparison diagram of the earthing switch blade of the Article 1 inlet wire L1 of the present invention,
Wherein earthing switch blade includes discoid rotating disk and the plug-in strip locking bolt lock BBL1 coordinated with rotating disk, rotating disk circle
It is disposed radially inwardly shrinkage pool P12, shrinkage pool P12 on week to coordinate with the dead bolt S1 of plug-in strip locking bolt lock BBL1；
The circle centre position of rotating disk is provided with radially outer handle P11, and handle P11 stretches out outside rotating disk in one end, another
End aligns with shrinkage pool P12.The first lock when handle P11 is in open position, corresponding to key A1
The dead bolt S1 of cutter lock dog inserts in shrinkage pool P12, and handle P11 is the most rotatable；Insert key A1 to first
Plug-in strip lock dog unlocks, and the dead bolt S1 corresponding to key A1 retracts, and now rotating disk can rotate, and rotation connects
Ground plug-in strip is to closing position, and now the dead bolt of shrinkage pool P12 alignment key B1, then rotates and extract A2
Key, the dead bolt of the second plug-in strip lock dog corresponding to key B1 ejects, then earthing switch blade is locked in conjunction
Gate position, now A1 key is in the lock state and can not extract.
Fig. 4 shows key in-out apparatus BEL4 in accordance with another embodiment of the present invention, and this key enters
Going out device BEL4 is to go out formula into three, depending on concrete turnover quantity can be according to actual operation requirements, such as
If five sections of inlet wires, five manhole door locks, it is simply that five enter five goes out.Key in-out apparatus BEL4 includes
Four lock dogs combined successively, its be respectively one enter lock dog and three go out lock dog, enter lock dog and three go out
Lock dog couples, and such as, enters the key B1 of lock dog and inserts and rotate, three three key C1 going out lock dog,
C2, C3 can rotate and extract.
Fig. 5 shows the manhole door door lock BDL2 with two series connection lock dogs that the present invention uses, manhole
Door lock includes two the first manhole door lock blocks coupled and the second manhole door lock dog, the first manhole door lock block
Mating with key C, the second manhole door lock dog has coupled key D, the second manhole door lock dog also with snap close
K1 coordinates.Such as, insert as two keys C1, the D1 taken out on key in-out apparatus BEL simultaneously
After entering the first manhole door lock block and rotating, extract key D1 key C1 simultaneously and be locked in manhole door door lock
On, snap close K1 can extract from lock body, and snap close K1 extracts rear manhole door and opens, now manhole door door lock
Snap close K1 cannot pin with lock body.
Again as it is shown in figure 1, use the anti-lock electrostatic precipitation room job step of machinery five of the present invention as follows:
Disconnect the Article 1 inlet wire L1 of 400V, extract first locking bolt lock BBL1 on first chopper
Key A1, then first chopper of the Article 1 inlet wire L1 of 400V is locked in off-position.
Second chopper of Article 2 inlet wire L2-L4 operate in the same way can extract key A2,
A3, A4, repeat the most one by one at this.
Unlock to first plug-in strip lock dog on first earthing switch blade P1 with key A1, operate first
Earthing switch blade P1 ground connection, then can extract the key B1 on second plug-in strip lock dog, and key B1 extracts
Rear earthing switch blade P1 is locked in ground state, and earthing switch blade P1 is inserted simultaneously into A1 key and A2
Key could decouple, indispensable.
Earthing switch blade 2-4 operates in the same way and can take out key B2, B3, B4, differs at this
One repeats.
Key B1, B2, B3, B4 are inserted on key in-out apparatus BEL10 correspondence enter on lock dog,
Rotate key B1, B2, B3, B4 then can use lock dog decoupling, thus rotate extract key C1,
C2, C3, C4, C5, C6, key C1, C2, C3, C4, C5, C6 extract rear key B1,
B2, B3, B4 are locked in above key in-out apparatus BEL10 and cannot extract.
Unlock to the first manhole door lock block of manhole door M1 with key C1, then rotate and extract key
D1 can open manhole door M1 and enter electrostatic precipitation room and carry out overhauling or other operations, and key D1 is not
When again turning back to the second manhole door lock dog of manhole door M1, manhole door lock BDL2 cannot lock, C1 key
Spoon cannot take out.
Manhole door M2-M6 in kind operates and can open, and repeats the most one by one at this.
Contrary operation can recover power transmission.
Above-described, only presently preferred embodiments of the present invention, it is not limited to the scope of the present invention,
The above embodiment of the present invention can also make a variety of changes.The most every right according to the present patent application is wanted
Ask change simple, equivalent and modification that book and description made, fall within the right of patent of the present invention
Claimed scope.The most detailed description of the present invention be routine techniques content.
