Description
Technical Field
The utility model belongs to the technical field of the armor formula of removing exchanges metal enclosed switchgear, especially, relate to a valve mechanism of operation safe and reliable.
Background
The armored movable AC metal-enclosed switchgear is a device frequently used in industrial production, and the valve mechanism is a core protection component of the armored movable AC metal-enclosed switchgear. The valve mechanism of the existing 35kV metal-enclosed switchgear is of a steel wire rope structure, and has the defects of easiness in tripping of the steel wire rope, complexity in installation and debugging, high technical requirements on processing and manufacturing personnel, easiness in electric shock accidents during maintenance and the like.
Disclosure of Invention
The utility model aims to improve the not enough and novel valve mechanism that a safe and reliable, flexible, the simple structure of linkage operation that provide of prior art.
The utility model aims at realizing like this, a novel valve mechanism, including cabinet side board, its characteristics are the lower part at cabinet side board is installed to the bottom hub mounting of the big splint of U-shaped valve, the bottom top of the big splint of valve is equipped with the recess that is used for holding the handcart drive shaft, big pull rod, the one end of lower valve pull rod respectively with the middle part of the big splint lower arm of U-shaped valve, the afterbody hub connection, the other end of big pull rod is connected with the one end hub connection of guide arm, the middle part hub mounting of guide arm is on cabinet side board, the other end of guide arm is connected with the one end of last valve pull rod, the other end of going up the valve pull rod is connected with the last valve hub connection of installing on last valve guide arm, the other end of lower valve pull rod is connected with the lower valve hub connection of installing on lower valve guide arm.
Compared with the prior art, the utility model has the following characteristics of showing and positive effect: the utility model discloses promote the big splint of valve and around the shaft motion by the handcart drive shaft, drive big pull rod, fire door pull rod motion down by the big splint of valve to the realization drives upper and lower valve switch, has realized that the handcart impels, releases and the purpose of upper and lower valve linkage, has the characteristics that the linkage is reliable, simple structure. The utility model discloses the effectual danger of having solved current valve mechanism wire rope and often having tripped has realized the mandatory that the valve was opened, has avoided maintainer to open the valve by mistake and the emergence of electric shock accident, has simple structure, preparation simple to operate, the fast characteristics of debugging, can effectively improve assembly efficiency, reduces the processing cost, is particularly useful for two take place ofs improvement type high-pressure complete sets.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is a schematic structural diagram of the valve mechanism of the present invention when it is opened.
Fig. 2 is a schematic structural diagram of the shutter mechanism of the present invention when closed.
In the figure: 1. the handcart type cabinet comprises a handcart driving shaft, 2, a valve large clamping plate, 3, a large pull rod, 4, a guide rod, 6, an upper valve guide rod, 8, an upper valve pull rod, 9, an upper valve, 10, a lower valve, 11, a lower valve pull rod, 12, a lower valve guide rod, 13 and a cabinet body side plate.
Detailed Description
A novel valve mechanism, refer to fig. 1 and fig. 2, a bottom shaft of a U-shaped valve large clamping plate 2 is installed at the lower part of a cabinet body side plate 13, a groove used for containing a handcart driving shaft 1 is arranged above the bottom of the valve large clamping plate 2, a large pull rod 3 and one end of a lower valve pull rod 11 are respectively connected with the middle part and the tail part of a lower arm of the U-shaped valve large clamping plate 2, the other end of the large pull rod 3 is connected with one end shaft of a guide rod 4, the middle part of the guide rod 4 is installed on the cabinet body side plate 13, the other end of the guide rod 4 is connected with one end of an upper valve pull rod 8, the other end of the upper valve pull rod 8 is connected with an upper valve 9 shaft installed on an upper valve guide rod 6, the other end of the lower valve pull rod 11 is connected with a lower valve 10 shaft installed on a lower valve guide rod 12.
When the handcart is pushed into the equipment, the handcart driving shaft 1 simultaneously rolls forwards along with the handcart, the valve large clamping plate 2 fixed on the cabinet body side plate 13 is pushed to downwards rotate by taking the shaft as a circle center, the valve large clamping plate 2 drives the large pull rod 3 and the lower valve pull rod 11 to downwards move, and the lower valve pull rod 11 drives the lower valve 10 to downwards slide along the lower valve guide rod 12, so that the lower valve 10 is opened; the large pull rod 3 drives the guide rod 4 to rotate around the shaft as a circle center while moving downwards, and the guide rod 4 drives the upper valve pull rod 8 and the upper valve 9 to slide upwards along the upper valve guide rod 6 while rotating, so that the upper valve 9 is opened; on the contrary, when the handcart is pulled out of the equipment, the handcart driving shaft 1 rolls backwards along with the handcart to the groove of the large valve clamping plate 2, the large valve clamping plate 2 is pulled to rotate upwards by taking the shaft as the center of a circle, the large valve clamping plate 2 drives the large pull rod 3 and the lower valve pull rod 11 to move in the opposite direction while rotating, the upper valve 9 slides downwards along the upper valve guide rod 6, and the lower valve 10 slides upwards along the lower valve guide rod 12, so that the upper valve and the lower valve are closed.
