Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
A valve self-locking structure of a medium-voltage switch cabinet comprises an upper valve sheet 1, a lower valve sheet 2, an upper connecting rod 3, a lower connecting rod 4, a middle connecting rod 5, a base 6 and a spring 7. The upper valve sheet 1, the lower valve sheet 2 and the middle connecting rod 5 are connected to the base 6 through pin shafts, and clamp springs are arranged on the pin shafts to axially fix parts on the shafts. The upper connecting rod 3 and the lower connecting rod 4 are arranged on the middle connecting rod 5 through hinge connection.
The base 6 is provided with a mounting hole. The upper connecting rod 3 and the lower connecting rod 4 have the same structure and are provided with a circular clamping groove 31, a fixing column 32 and a spring mounting hole 33. The circular clamping groove 31 is a semi-circular notch on the upper connecting rod 3 and the lower connecting rod 4. The two springs 7 are provided, one end of one spring 7 is connected with the spring mounting hole 33 of the upper connecting rod 3, the other end of the spring 7 is connected with the middle connecting rod 5, and one end of the other spring 7 is connected with the spring mounting hole 33 of the lower connecting rod 4, and the other end of the spring 7 is connected with the middle connecting rod 5.
The upper valve piece 1 and the lower valve piece 2 are similar in structure and are provided with idler wheels 11, the idler wheels 11 are matched with the circular clamping grooves 31 in shape, and the idler wheels 11 are cylindrical and can rotate relative to the upper valve piece 1 and the lower valve piece 2.
The specific working principle of this embodiment is as follows:
a valve self-locking structure of a medium-voltage switch cabinet is fixed on a side plate of the switch cabinet through a mounting hole on a base 6.
When the circuit breaker is at a test position or not in the cabinet, the round clamping grooves 31 on the upper connecting rod 3 and the lower connecting rod 4 clamp the rollers 11 on the upper valve sheet 1 and the lower valve sheet 2, so that the upper valve sheet 1 and the lower valve sheet 2 cannot act, and the valves cannot be opened.
When the circuit breaker is moved from the test position to the working position, the valve push plates on the left side and the right side of the circuit breaker push the upper connecting rod 3 and the upper fixing column 32 on the lower connecting rod 4 to enable the upper connecting rod 3 to move anticlockwise and downwards around the pin shaft, the lower connecting rod 4 moves clockwise and upwards around the pin shaft, the circular clamping grooves 31 of the upper connecting rod 3 and the lower connecting rod 4 are separated from the roller 11 of the upper valve piece 1 and the lower valve piece 2, and therefore the valve is opened by the movement of the upper valve piece 1 and the lower valve piece 2 driven by the valve push plates on the left side and the right side of the circuit breaker. When the circuit breaker moves from the working position to the testing position, the self-locking mechanism is restored under the action of the spring 7 connected with the tail parts of the upper connecting rod 3 and the lower connecting rod 4.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
