Abstract
A five-prevention locking lock catch device for a high-voltage circuit breaker cabinet comprises a screw fastened to a rear door board of a high-voltage switch cabinet. A square locating sheet is further fastened to the rear door board through the screw. The two symmetric edges of the locating sheet are perpendicularly connected with a connecting sheet and an insertion sheet to form a U-shaped locating seat sheet. A connecting cover sheet which can be turned and provided with an insertion groove hole is hinged to the edge of the outer end of the connecting sheet through a pin shaft. An externally-protruding hinging sheet which can be inserted in the insertion groove hole in the connecting cover sheet in a matched manner and provided with a locking hole in the end is arranged on the edge of the outer end of the insertion sheet. The two sides of the cover sheet are connected with two inside sheets which are integrated and are perpendicular. The two inside sheets can be clamped to the two sides of the U-shaped locating seat sheet when the connecting sheet and the insertion sheet on the two sides of the U-shaped locating seat sheet are covered with the cover sheet, so that a cavity with the sealed interior is formed by the U-shaped locating seat sheet and the cover sheet. The five-prevention locking lock catch device has the beneficial effects that the structure is simple and various high-voltage switch cabinets needing to be operated in a substation can be effectively managed and controlled.
Description
Technical field
What the present invention relates to is a kind of high-voltage circuit breaker cabinet five-defence block locker, belongs to the secure latch technical field of electric substation's high-tension switch cabinet.
Background technology
At present, the high-voltage switch cabinet door of electric substation all will install anti-misoperation locking device substantially, but existing back door of high-tension switch cubicle plate is still installed with original holding screw, staff is in maintenance process, time have the holding screw gone to the wrong way interval or tear high voltage cabinet door by mistake open, thus initiation electric shock accidents, its reason is also to lack effectively in prior art, reliable blocking device, simultaneously because the screw bearing on back door of high-tension switch cubicle plate has groove mostly, therefore existing general locking closes device by mistake, all be not suitable with and install at this, thus there are some potential safety hazards, easily cause the generation of the accidents such as maloperation.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and provide a kind of structure simple, easy to use, reliable, good looking appearance, can to the various high-voltage circuit breaker cabinet five-defence block lockers needing the high-tension switch cabinet of operation to carry out effective management and control in electric substation.
The object of the invention is to have come by following technical solution, a kind of high-voltage circuit breaker cabinet five-defence block locker, it comprises a screw fastening on back door of high-tension switch cubicle plate, described Rear Door is also fastened with a square spacer by described screw, two Symmetry Edge vertical connections of this spacer have a connecting piece and an insert-connecting plate, and form a U-shaped positioning seat sheet; In the outer end edges of described brace with hinge have one reflexibie, connect cover plate with grafting slotted eye; The outer end edges of described insert-connecting plate be provided with evagination, can with to be connected on cover plate with grafting slotted eye coordinate insert, end is with the mounting sheet of lockhole.
As preferably: described cover plate both sides are also connected to two inside piece in vertical configuration of one, and two inside piece can be interposed in U-shaped positioning seat sheet both sides when cover plate covers brace and the insert-connecting plate on U-shaped positioning seat sheet both sides, make U-shaped positioning seat sheet and cover plate form the cavity of enclose inside.
As preferably: the spacer that the centre of described U-shaped positioning seat sheet is rectangle by the screw fastening of hexagonal cylindrical head in described employing on the Rear Door of high-tension switch cabinet.
It is simple that the present invention has structure, easy to use, reliable, good looking appearance, can carry out the features such as effective management and control to the various high-tension switch cabinets of operation that need in electric substation.
Accompanying drawing explanation
Fig. 1 is five anti-snap close unlocking structure schematic diagrames of the present invention.
Fig. 2 is five anti-snap close blocking schematic diagrames of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1, a kind of high-voltage circuit breaker cabinet five-defence block locker of the present invention, it comprises a screw 2 fastening on back door of high-tension switch cubicle plate 1, described Rear Door 1 is also fastened with a square spacer 12 by described screw 2, two Symmetry Edge vertical connections of this spacer 4 have a connecting piece 3 and an insert-connecting plate 4, and form a U-shaped positioning seat sheet; In the outer end edges of described brace 3 with bearing pin 5 be hinged with one reflexibie, connect cover plate 6 with grafting slotted eye 8; The outer end edges of described insert-connecting plate 4 be provided with evagination, can with to be connected on cover plate 6 with grafting slotted eye 8 coordinate insert, end is with the mounting sheet 9 of lockhole 7.
Shown in figure, cover plate 6 both sides of the present invention are also connected to two inside piece 10 in vertical configuration of one, and two inside piece 10 can be interposed in U-shaped positioning seat sheet both sides when cover plate 6 covers brace 3 and the insert-connecting plate 4 on U-shaped positioning seat sheet both sides, U-shaped positioning seat sheet and cover plate 6 is made to form the cavity of enclose inside, become five safe anti-snap close blockings, in lockhole 7, realize locking with lockset 11 interlocking.
The spacer 12 that the centre of U-shaped positioning seat sheet of the present invention is square is fastened on the Rear Door 1 of high-tension switch cabinet by the screw 2 of hexagonal cylindrical head in described employing.
The present invention when locking is installed, do not need to construction high-tension switch cabinet have a power failure after install, be specially adapted to the electric substation of having gone into operation; The switchboard of band high-tension electricity is a little sent to carry out improving and improvement and installation of five anti-devices.
