Abstract
The utility model discloses a door lock for a box-type substation, and belongs to the technical field of substations. The door lock for the box-type substation comprises a shell and a lock core, wherein a blind hole is formed at the middle position of the shell; the lock core is arranged in the blind hole; and a cover plate is arranged at the opening of the blind hole. The cover plate covers the lock core so as to stop rainwater, so that the rainwater is prevented from entering the lock core through the lock hole in the lock core, and the corrosion damage of the interior of the lock core is avoided.
Description
Technical field
The utility model belongs to transformer station's technical field, especially relates to a kind of door lock of box-type substation.
Background technology
Box-type substation is a kind of high voltage switchgear equipment, distribution transformer and low-voltage distribution equipment; Line up indoor, the outdoor close-coupled controller switching equipment of prefabrication of one by certain connection plan; Being about to functions such as high powered, transformer step-down, low-voltage distribution organically combines; Be installed in a protection against the tide, antirust, dustproof, protection against rodents, fire prevention, antitheft, heat insulation, totally-enclosed, movably in the steel work casing, electromechanical integration, totally-enclosed operation; Being specially adapted to city net construction and upgrading, is a kind of brand-new transformer station that after civil engineering transformer station, emerges.Box-type substation is applicable to mine, factory and enterprise, oil gas field and wind power station, and it has substituted original civil engineering power distribution room, and power substation becomes novel complete change power distribution equipment.
Box-type substation maintenance personal work for ease, the outside door that can open that all is provided with, door is provided with door lock, prevents that the unrelated person entering from causing danger.Because the box-type substation operated by rotary motion out of doors, the lockhole of general box-type substation door lock is exposed to outer again, accepts wind and weather for a long time, and it is inner that rainwater constantly gets into lock core through lockhole, and the time one will be caused the inner corrosion and damage of lock core for a long time.
Summary of the invention
The utility model provides a kind of door lock of box-type substation to deficiency of the prior art, and lock core is damaged by wind and weather.
For solving the problems of the technologies described above; The utility model is able to solve through following technical proposals: the door lock of box-type substation, comprise shell and lock core, and the centre position of said shell is provided with blind hole; Said lock core is arranged in the said blind hole, and the opening part of said blind hole is provided with cover plate.Utilize cover plate to cover lock core, stop rainwater, prevent that the lockhole that rainwater passes through on the lock core from getting into lock core inside, causes the inner corrosion and damage of lock core.
In the technique scheme, preferred, said cover plate one end is hinged on the said shell.When need unblank, can cover plate be opened, in the time of at ordinary times, cover plate covers on blind hole.Cover plate links to each other with shell like this, makes that cover plate is not easy to lose.
In the technique scheme, preferred, said cover plate is provided with magnet.Magnet is used to prevent open automatically when cover plate from receiving external force.
In the technique scheme, preferred, the lower end position of said blind hole opening forms groove.Finger can stretch in the groove, and an end in contact not hinged with cover plate can be opened cover plate easily.
The beneficial effect of the utility model is: utilize cover plate to cover lock core, stop rainwater, prevent that the lockhole that rainwater passes through on the lock core from getting into lock core inside, causes the inner corrosion and damage of lock core.
Description of drawings
Fig. 1 is the sketch map of the utility model embodiment.
Fig. 2 is the sectional view of Fig. 1 along A-A.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail: referring to Fig. 1 to Fig. 2; The door lock of box-type substation; Comprise shell 1, lock core 2 and cover plate 3, the centre position of shell 1 forms the blind hole 12 of rectangle, and lock core 2 is fixed in the blind hole 12.The opening part of blind hole 12 forms a circle convexity 13, and the lower end of blind hole 12 forms stop part 14, and rotating shaft 4 is rotatably connected on the convexity 13 on shell 1 top after passing cover plate 3 upper ends; Be that cover plate 3 is hinged on the shell 1 through rotating shaft 4; Also be fixed with a magnet 31 on the medial surface of cover plate 3 lower ends, when cover plate 3 was in closed condition, the magnet 31 of the lower end of cover plate 3 contacted with stop part 14; Stop part 14 is processed by ferrimagnet, and magnet 31 relies on magnetic and stop part 14 adhesives.
The midway of the lower end of blind hole 12 openings forms groove 11.In the time of need opening cover plate 3, finger can stretch in the groove 11, and an end in contact not hinged with cover plate 3 can be opened cover plate 3 easily.
