Further, the second rotating shaft is located below the contact box, and the second rotating shaft is higher than the center of the contact box.

Further, the first valve and the second valve are made of non-metal materials.

The utility model discloses a theory of operation: when the handcart returns to the test position from the working position, the bending rod moves upwards and the upper pull plate and the lower pull plate move upwards under the pulling of the return spring along with the backward movement of the handcart wheels, and the two valves are gradually reset. When the handcart moves from the test position to the working position, the wheels of the handcart downwards press the bending rod to enable the bending rod to rotate clockwise around the first rotating shaft, and the lower pulling plate downwards moves under the driving of the bending rod; the first valve rotates anticlockwise around the second rotating shaft under the pulling of the lower pulling plate, meanwhile, the second pulling plate also moves downwards under the pulling of the lower pulling plate, the second valve is driven to rotate clockwise, and the upper first valve is gradually opened in place.

(2) Advantageous effects

The utility model has the advantages that: compared with the prior art, the utility model discloses simple structure, the transmission link is less, the action is light and handy nimble reliable, when the handcart is shaken out, the valve is closed, when the handcart is shaken into, the valve is opened inwards, and compare with the translation formula, the distance that the valve was opened the back and is touched the wall and be qualified for the next round of competitions the seat from the handcart is farther, more help improving the dielectric strength between valve and handcart, improve the security performance of the cabinet body, the high tension switchgear valve structural design of having solved prior art is complicated, the transmission link is more, difficult maintenance, and the valve is opened the back and is touched the wall and be qualified for the next round of competitions the seat from the handcart near, there is the technical problem of.

Detailed Description

The present invention will be further described with reference to the following examples.

Example one

Referring to fig. 1, the embodiment provides a rotary high-voltage cabinet valve structure, which includes a bending rod 1, a handcart wheel 2, a hanging spring bent plate 3, a valve return spring 4, a lower pull plate 5, a first valve 6, a first valve fixed bent plate 7, a second pull plate 8, a second valve 9, a second valve fixed bent plate 10 and a contact box 11, the rotary high-voltage cabinet valve structure is symmetrically arranged on two sides of a high-voltage cabinet body, the bending rod 1 can rotate around a first rotating shaft 101, the valve return spring 4 is hung on the bending rod 1 and a connecting pin shaft connected with the lower end of the lower pull plate 5 through a pin shaft, the other end of the valve return spring 4 is hung on the hanging spring bent plate 3, the upper end of the lower pull plate 5 is rotatably connected with a second rotating shaft 102, the upper end of the lower pull plate 5 is connected with the lower ends of the first valve 6 and the second pull plate 8 through a pin shaft, the upper end of the second pulling plate 8 is connected with the second valve 9 through a pin shaft, the first valve 6 is connected with a fixed bent plate of the first valve 6 fixed on the high-voltage cabinet body through a pin shaft, the first valve 6 can rotate around a fulcrum, the second valve 9 is connected with the fixed bent plate of the second valve 9 fixed on the high-voltage cabinet body through a pin shaft, and the second valve 9 can rotate around a third rotating shaft 103.
