The present invention is used to complete the determination of the working sequence of the actuator, which can ensure the safety of current conduction.

Description

Technical Field

[0001] The present invention belongs to the field of rotatable large-current busbar devices, and particularly relates to an actuator working sequence determination device for a rotating busbar device. Background Art

[0002] The rotating busbar device generally consists of multiple sectors evenly distributed on a 360° circumference. Each sector works independently and generally cannot be connected in series. The crimping actuators are evenly distributed along the circumference between the stator and rotor of the rotating busbar device. Without restrictions, at a specific angle, the actuator will straddle between two sectors, and current conduction at this time will cause serious damage to the load. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides an actuator working sequence determination device for a rotating busbar device, which completes the function of making a specified actuator work at a specific angle. Through the on / off states of multiple photoelectric sensors, it can automatically determine the angle of rotation of the rotor, prevent the actuator located at the sector edge from performing the crimping action, ensure the safety of current conduction, and realize the determination of the working sequence of the actuator at a specific angle.

[0004] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] An actuator working sequence determination device for a rotating busbar device is composed of a circular code disk, an upper outer photoelectric sensor, a lower outer photoelectric sensor, an upper inner photoelectric sensor, and a lower inner photoelectric sensor; the circular code disk is fixed below the rotor of the rotating busbar device, and the upper outer photoelectric sensor, the lower outer photoelectric sensor, the upper inner photoelectric sensor, and the lower inner photoelectric sensor are divided into two groups and longitudinally arranged on both sides of the side wall of the circular code disk, and are fixed on the base; the on / off states of the optical paths of the upper outer photoelectric sensor, the lower outer photoelectric sensor, the upper inner photoelectric sensor, and the lower inner photoelectric sensor at different angles are used to control the work of a specific actuator, and the determination of the working sequence of the actuator is completed.

[0006] Further, the circular code disk is evenly divided into 12 groups along the circumferential direction, with each group being 30°; in the vertical direction, it includes two modes: on and off, with the side wall being hollow for on and solid for off.

[0007] Further, when the rotation angle is between 2n×30° and (2n + 1)×30°, the upper outer photoelectric sensor and the upper inner photoelectric sensor are blocked, and the lower outer photoelectric sensor and the lower inner photoelectric sensor are turned on. At this time, it is determined as the crimping of the even-numbered group; when the rotation angle is between (2n + 1)×30° and (2n + 2)×30°, the upper outer photoelectric sensor, the upper inner photoelectric sensor, the lower outer photoelectric sensor, and the lower inner photoelectric sensor are blocked. At this time, it is determined as the crimping of the odd-numbered group.

[0008] Beneficial effects:

[0009] Through the on / off of the first to fourth photoelectric sensors, the present invention can automatically determine the working sequence of the actuator, restrict the movement of the actuator, prevent the actuator from connecting two different sectors at a specific angle, and avoid the risk of damage to the load caused by current flow.

[0019] The present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0020] Generally, the rotary current collecting device is divided into multiple sectors, and each sector is connected to a branch load. Each sector is independent of each other, and the connection between the stator and the rotor is realized through the crimping of the actuator.

[0021] Such as Figure 1As shown in the figure, a device for determining the working sequence of an actuator for a rotary current collecting device according to the present invention is composed of a circular code disk 5, an upper outer photoelectric sensor 1, a lower outer photoelectric sensor 2, an upper inner photoelectric sensor 3, and a lower inner photoelectric sensor 4. The circular code disk 5 is fixed below the rotor of the rotary current collecting device. The upper outer photoelectric sensor 1, the lower outer photoelectric sensor 2, the upper inner photoelectric sensor 3, and the lower inner photoelectric sensor 4 are divided into two groups and longitudinally arranged on both sides of the side wall of the circular code disk 5 and fixed on the base. By controlling the on-off of the optical paths of the upper outer photoelectric sensor 1, the lower outer photoelectric sensor 2, the upper inner photoelectric sensor 3, and the lower inner photoelectric sensor 4 at different angles, a specific actuator is controlled to work, and the determination of the working sequence of the actuator is completed, which can ensure the safety of current conduction.

[0022] The circular code disk 5 is fixed below the rotor of the rotary current collecting device and is evenly divided into 12 groups along the circumferential direction, with each group being 30°. In the vertical direction, it includes two modes: on and off. The side wall is hollow for on and solid for off. When the rotation angle is within 2n×30° to (2n + 1)×30°, as Figure 2 shown, the upper outer photoelectric sensor 1 and the upper inner photoelectric sensor 3 are blocked, and the lower outer photoelectric sensor 2 and the lower inner photoelectric sensor 4 are turned on. At this time, it is determined as the crimping of even-numbered groups; when the rotation angle is within (2n + 1)×30° to (2n + 2)×30°, as Figure 3 shown, the upper outer photoelectric sensor 1, the upper inner photoelectric sensor 3, the lower outer photoelectric sensor 2, and the lower inner photoelectric sensor 4 are blocked. At this time, it is determined as the crimping of odd-numbered groups, and so on.

However, the present invention is not limited by the above embodiments and can be modified within the scope of the claims. If changes, substitutions, combinations, simplifications are made under the inspiration of the technical solutions of the present invention and are not substantial changes, as long as they meet the purpose of the present invention and do not deviate from the technical principle and inventive concept of the present invention, they all fall within the protection scope of the present invention.
