Description

A kind of mazy high pressure switchgear assembly door

Technical field

The present invention relates to a kind of high pressure switchgear assembly, relate in particular to a kind of mazy high pressure switchgear assembly door.

Background technology

At present, there are some wretched insufficiencies in high pressure switchgear assembly door:

One of which, what be that existing high-voltage board door lock adopts is the folding of bolted mode, the Chinese patent document; Publication number: CN2534412, application number: 00240212.2, the applying date: 2000.11.21; Open day: 2003.02.05, the patentee: Qingtian Electric Industry Co., Ltd., Guangzhou discloses " high pressure switchgear assembly door lock "; It comprises lock tube, alignment pin, locking bar, back-up ring etc., it is characterized in that locking bar by lock rod head, connects slide block and screw rod three parts and is formed by connecting; The lock rod head front end has round recessed, and pothole is arranged in the groove, the installing and locating pin, and there is a projection rear end; Grooved hole on it, connecting the slide block front and back end has mutually perpendicular U type groove, and two groove parts have pin-and-hole, and screw front end has projection; Projection part grooved hole, there is screw thread the rear end, through slotted eye and U-lag the locking bar each several part is linked into an integrated entity by connecting pin; Can be free movable between each connector because of connecting pin, screw rod can be moved up and down and the secured in alignment part, improved the installation effectiveness and the fail safe of equipment; But this high-voltage board door lock need expend that rotation that the long period carries out locking bar just can be opened or be closed, and the switch door is inconvenient;

Its two, be the cabinet door adopt basically the welding or two ruffle mode strengthen, processed complex, precision is difficult to be protected;

Its three, be that the door degree of protection is poor, the environment for use under the abominable situation that can not satisfy condition;

Its four, be that the high-tension switch cabinet pressure release is the directly ejection from the front, a safety inadequately when door is opened.

Therefore design and develop a kind of simple in structurely, precision, degree of protection are high, can realize that the emergency exit structure of quick operating valve has great importance.

Summary of the invention

Technical problem to be solved by this invention provides a kind of mazy high pressure switchgear assembly door, and it is quick that it has the switch door, and the processing of cabinet door is simple and machining accuracy is high, and water proof and dust proof sealing grade is high, door pressure release mode science, safe and reliable characteristics.

For solving the problems of the technologies described above, the present invention adopts following technical proposals: a kind of mazy high pressure switchgear assembly door, and it comprises the breaker chamber door and is fixed in the door lock on the breaker chamber door; Said door lock is a link lock; It is fixed in the top of breaker chamber door, and the link lock end wears out the framework of breaker chamber door one side, and said breaker chamber door comprises a body, door movable part, hinge and at least two axle and shaft sleeve device that can slide up and down cooperation; Each axle that can slide up and down cooperation is fixedly connected with the door movable part with the door body respectively with shaft sleeve device; Hinge is fixed in an end, side, is the center of circle with the hinge, and the opening angle of door is greater than 90 degree; The outer surface of door body is equipped with spacing protuberance; Be installed with handle on the said door movable part, said door movable part is provided with the strip through hole to the spacing protuberance place of the body of answering the door, and the door movable part slides up and down through axle and shaft sleeve device and is matched with the side that a body is provided with spacing protuberance; Said spacing protuberance is located in the strip through hole and the upslip of limiting door movable part leaves, and said link lock is sliding through going up of horizontal displacement limiting door movable part.

Top, the side end face respective link lock position that said door body is provided with spacing protuberance one side offers limiting through hole, and the link lock end on the door body is arranged in this limiting through hole; Door body both sides end face offers the fixing through hole of using, and this is fixed with through hole and is fixedly connected with hinge and axle and shaft sleeve device respectively.

Also offer breaker chamber observation window, circuit breaker rocking bar patchhole and breaker chamber door gusset fixing hole on the door external surface; This breaker chamber door gusset fixing hole place is fixed with the breaker chamber door gusset that can horizontally slip, and exposes circuit breaker rocking bar patchhole during rocker switch; Said door body inner surface circumferentially is installed with reinforcement, and the reinforcement outer is concaved with the airtight loop of the labyrinth type that is bonded with sealing strip groove, and this is bonded with the airtight framework place of the airtight loop groove location of sealing strip corresponding to breaker chamber inside; Corresponding to being fixed with flat on the door body inner surface between the left and right strengthening ribs of breaker chamber observation window position, so that under the situation of breaker chamber sealing, observe the situation of breaker chamber inner breaker; Door body inner surface is fixed with the breaker chamber door lining of being with metal sleeve corresponding to circuit breaker rocking bar patchhole position, accurately inserts for the circuit breaker rocking bar circuit breaker is shaken into or shakes out.

The cross section of said door movable part is " L " font; Cross section is on long-armed of " L " font and offers strip through hole and handle fixing hole; Handle passes through bolt in handle fixing hole place; Cross section is and offers axle and shaft sleeve device fixing hole on the galianconism face of " L " font; Be used for axle and shaft sleeve device and door movable part through bolt, side end face respective shaft and shaft sleeve device fixing hole position that cross section is the galianconism face of " L " font offer gap, in order to axle and shaft sleeve device fixing and spacing.

Said each axle comprises two door fixed hubs, a breaker chamber fixed hub, a door movable part fixed hub, an axle and a pin with shaft sleeve device; Said axle from top to bottom is arranged in a movable part fixed hub, door fixed hub, breaker chamber fixed hub and the door fixed hub successively; One end of axle is fixed in the movable part fixed hub through pin, and axle is slidingly connected with two door fixed hubs and a breaker chamber fixed hub; Be equipped with projection on said door fixed hub and the breaker chamber fixed hub; Said each be individually fixed in the fixing through hole of using of the door side end face that is connected with a movable part with the projection of two door fixed hubs of shaft sleeve device; And the projection direction of breaker chamber fixed hub is perpendicular to the projection direction of door fixed hub; The projection of breaker chamber fixed hub is fixed on the circuit breaker locular wall; Said door movable part fixed hub is provided with screwed hole, and this screwed hole is solid with shaft sleeve device fixing hole contraposition spiral shell with the axle of door movable part through bolt.
