Technical Field

The utility model relates to a dual power transfer switch technical field especially relates to a rotation type energy storage operating device of bidirectional operation.

Background

Dual power transfer switches (ATSE) are a common type of low voltage power distribution element used to switch between two power sources to ensure continuous power to a load. Namely, when one normally used power supply fails, the dual power supply changeover switch automatically switches to the other standby power supply connected with the dual power supply changeover switch.

The operating mechanism of the dual-power transfer switch is divided into an electric operating mechanism and a manual operating mechanism. Generally, the switching of the dual power transfer switch is mainly controlled by using an electric operating mechanism, but when the electric operating mechanism breaks down or needs maintenance, the switching of the dual power transfer switch needs to be performed by using a manual operating mechanism. The manual operation mechanism of the dual-power transfer switch is divided into two modes of related manual operation and unrelated manual operation. The manual operating mechanism of the prior dual-power transfer switch is almost all related to manual operation, namely the moving speed of the movable contact of the transfer switch is related to the operating speed of the manual operating mechanism for moving the movable contact. This requires that the operator must disconnect the front-end power supply or the rear-end load when performing manual operation, otherwise, the speed of the manual operation is unstable, which results in uncontrollable electric arc generated between the moving contact and the stationary contact, which leads to serious safety problems.

The utility model discloses a rotation type energy storage operating device of two-way operation, in the embodiment of a preferred, rotation type energy storage operating device's stereogram is as shown in figure 1, including fixed support 1, support 1 is preferably the bilateral symmetry shape. The lower portion of the bracket 1 is provided with a rotation hole into which a main shaft 5 is inserted to be rotatable. The support 1 is rotatably connected with a driving sheet 2 by taking the rotating hole as a circle center, and the plane of the driving sheet 2 is preferably approximately parallel to the plane of the support 1. In a preferred embodiment, the spindle 5 also rotatably passes through the driver blade 2. The driving plate 2 is preferably of a left-right symmetrical structure, and particularly preferably of a fan-shaped structure, and the spindle 5 is rotatably inserted into the center of the fan.

The upper part of the plane of the bracket 1 is preferably at the same height, and two separated half shafts 32, a first half shaft and a second half shaft, are rotatably fixed; the half-shaft 32 is of a cylindrical-like configuration but has a portion of its side surface comprising a flat portion which is smoothly connected to a circular arc portion, but which flat portion is at a smaller radius than the circular arc portion, i.e. the flat portion is flatter and preferably planar than the circular arc portion. In particular, the flat portion is located between the circular arc portion and the rotational axis of the half shaft.

The driving plate 2 is provided with an arc-shaped channel 21 which is opposite to the half shaft 32 and takes the rotating hole as a circle center, and the arc-shaped channel 21 comprises a lower edge close to the rotating hole and an upper edge away from the rotating hole. The half shaft 32 is inserted into the arc-shaped channel 21, and when the driving plate 2 rotates around the main shaft 5, the arc-shaped channel 21 slides along the half shaft 32.

In a preferred embodiment, in order to allow the half shaft 32 to rotate in a certain position when sliding along the arc-shaped slot 21, i.e. to automatically make the flat part face downwards, or part of the arc part face downwards, as shown in fig. 2, a push rod 31 is fixedly connected to the side surface of the half shaft 32, and the push rod 31 is preferably connected to the intersection of the flat part and the arc part and extends outwards along the flat part. The free end of the push rod 31 falls to and moves along the lower edge. And, both ends of the lower edge are respectively provided with a protruding part 211 protruding smoothly towards the inside of the arc-shaped channel 21 and a recessed part 212 recessed towards the direction of the main shaft 5, when the free end of the push rod 31 slides along the arc-shaped channel 21, the protruding part 211 forces the free end of the push rod 31 to move upwards and then fall down to the recessed part 212, and the half shaft 32 is driven to rotate, so that the flat part correspondingly rotates downwards. In order to ensure that the free end of the push rod 31 remains seated on the lower edge, in a preferred embodiment, the free end of the rod portion is fixedly connected to a weight so as to keep the free end always sliding on the lower edge.

As shown in fig. 3, a driven plate 7 is fixedly connected to the main shaft 5, and the upper end of the driven plate 7 is lower than the flat portion, that is, when the flat portion is rotated toward the main shaft 5, for example, when the weight is dropped into the recess, the flat portion, for example, a flat surface, is rotated downward, and the driven plate 7 can pass through the half shaft 32 from the lower portion of the flat portion; but at the same time, the upper end of the driven plate 7 is higher than the lowest point of the circular arc part, so long as the circular arc part is partially rotated to the lower side and is opposite to the upper end of the driven plate 7, the upper end of the driven plate 7 is blocked from rotating to pass through. Considering that the driven plate 7 performs a rotational motion around the center of the rotary hole, it is preferable that the flat portion is a curved surface formed by an arc line centered around the center of the rotary hole.

In another embodiment, the upper end of the driven plate 7 is also lower than the lowest point of the circular arc portion, as shown in fig. 4, a lock catch 33 is disposed between the upper end of the driven plate 7 and the half shaft 32, and the lock catch 33 is rotatably fixed on the bracket 1, as shown in fig. 5.

And the driving plate 2 and the driven plate 7 are connected and driven through an elastic structure, and the elastic structure is preferably a spring. In operation, the resilient structure may drive the driven plate 7 to follow the driving plate 2, but a certain amount of relative movement is still permitted between the driven plate 7 and the driving plate 2 within the resilient range of the resilient structure. Specifically, when the driving plate 2 starts to rotate, the driven plate 7 is kept not to rotate, and the main shaft 5 is also driven to rotate, because the arc portion of the half shaft 32 faces the upper end of the driven plate 7 at this time, and the upper end of the driven plate 7 is blocked from rotating to pass through. At this time, the elastic structure between the driving plate 2 and the driven plate 7 is compressed or stretched, and mechanical energy is accumulated and stored until the free end of the push rod 31 passes through the convex part 211 and falls on the concave part 212, so that the half shaft 32 is driven to rotate, the flat part faces downwards, the upper end of the driven plate 7 is allowed to rapidly pass through the first half shaft on the same side from the lower part of the flat part under the elastic pressure accumulated by the elastic structure, and the other side of the second half shaft on the other side is reached. Because the push rod 31 on the second half-shaft is now in the opposite direction, it does not impede the rotation of the second half-shaft in the opposite direction.

In a preferred embodiment, as shown in fig. 3, the driving plate 2 includes left and right wings, and the driven plate 7 is a cross structure including a cross bar crossed with a vertical bar, both ends of the cross bar are respectively connected with a wing on the same side through at least one spring 412. When the driving plate 2 rotates in one direction, the spring 412 on the same side in the one direction is compressed, the spring 412 on the opposite side is stretched, and mechanical energy is accumulated. And at the later stage, when the half shaft 5 rotates and the upper end of the vertical rod is released, the accumulated mechanical energy is suddenly released, and the driven piece 7 is pushed to rotate rapidly under the elastic force.

Alternatively, in another embodiment, as shown in fig. 2, the driving plate 2 is designed as a sector, a driving column 22 is fixedly arranged in the middle of the sector, and two cross rods, a first cross rod 41 and a second cross rod 42, are rotatably connected to the main shaft, and are also connected to each other through springs and are linked to each other, the driving column 22 is located between the upper support rods of the two cross rods, and at least one, preferably two, of the cross rods are elastically connected to the driven plate 7. And, more preferably, in order to prevent mutual interference, it is convenient to arrange that the cross bar and the driven plate 7 are respectively provided at both sides of the driving plate 2. During operation, the driving plate 2 rotates to drive the driving post 22 to rotate, so as to force the first cross rod 41 to rotate along with the driving post, and the second cross rod 42 is also driven to rotate in the same direction through the spring. Meanwhile, the driven plate 7 is also driven to rotate through elasticity.

To sum up, the utility model discloses a two-way operation's rotation type energy storage operating device, the driven plate 7 is connected through elastic construction to the driving plate 2, at the rotatory in-process of driving plate 2, block the rotation of driven plate 7 through semi-axis 32, elastic construction keeps and accumulates the elastic force to driven plate 7, until driving plate 2 changes to the particular position, semi-axis 32 can rotate, allow driven plate 7 rotatory under the elastic action, it is rotatory to drive main shaft 5 to with the mode of sudden release, dynamics and speed when having guaranteed driven plate 7 release at every turn always keep unanimous.
