Description
Technical Field
The utility model relates to a power equipment specifically is a drive structure of three-phase switch.
Background
The static contact of the large three-phase switch is fixed on the insulating terminal, the moving contact is fixed on the other insulating terminal, and the connection and disconnection of the circuit are formed by the contact and disconnection of the moving contact and the static contact. Since the large-sized switch is installed at a high position and has many peripheral power devices, and an arc is easily generated when the switch is turned on and off, it is necessary to perform an opening and closing operation by a switch driving structure.
The existing operation driving structure has a plurality of structural forms and is relatively complex; since the driving structure is exposed outdoors, parts of the driving structure are easily rusted, resulting in poor operation.
Disclosure of Invention
In order to solve the technical problem, the utility model aims to provide a closed switch driving structure, which comprises a box body, wherein a crank arm is arranged in the box body, and a rotating shaft of the crank arm is connected with a driving handle; the crank arm is in shaft connection with one end of the primary transmission pull rod, and the other end of the primary transmission pull rod is in shaft connection with the touch pulley; the touch pulley is provided with a sliding chute, and the sliding chute corresponds to a sliding rail arranged on the box body; the touch pulley is in shaft connection with one ends of the two secondary transmission pull rods, and the other ends of the secondary transmission pull rods are in shaft connection with the interphase connecting rod; the interphase connecting rod is in shaft connection with the outer end of the linkage connecting lever, and the inner end of the linkage connecting lever is fixed with a turntable arranged on the outer side of the box body; the rotating shaft of the turntable is fixed on the box body; the box body is also provided with a box cover, and the box cover is fixed below the box body.
The two-stage transmission pull rods are symmetrically arranged, and correspondingly, the alternate connecting rods are also symmetrically arranged.
The rotary tables are in three pairs, the insulating terminals are arranged on the rotary tables, and the insulating terminals of each pair of rotary tables are respectively provided with a static contact and a moving contact.
The crank arm is fixed with an output shaft of the motor.
The utility model has the advantages that: due to the arrangement of the box body, the box body not only bears the connection of the components, but also protects the components, prevents rain and snow from corroding the components, and prolongs the service life; the structure is simple, the operation is flexible, and the device can be widely applied to power switches and corresponding equipment.

Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the position A-A of FIG. 1;
fig. 3 is a schematic diagram of a transmission structure.
Detailed Description
The utility model is described in detail with the following figures, as shown in the figures, the utility model comprises a box body 7, a crank arm 1 is arranged in the box body, if manual operation is adopted, a rotating shaft 11 of the crank arm 1 is connected with a driving handle 10; if the crank arm 1 is driven by a motor, the crank arm is fixed with an output shaft of the motor.
The crank arm 1 is in shaft connection with one end of a primary transmission pull rod 2, and the other end of the primary transmission pull rod 2 is in shaft connection with a touch pulley 3; the touch pulley is provided with a sliding chute, and the sliding chute corresponds to a sliding rail 8 arranged on the box body; the touch pulley is in shaft connection with one ends of two secondary transmission pull rods 4, and the other ends of the secondary transmission pull rods 4 are in shaft connection with an alternate connecting rod 5; the interphase connecting rod 5 is in shaft connection with the outer end of a linkage connecting lever 6, and the inner end of the linkage connecting lever is fixed with a turntable 9 arranged on the outer side of the box body; the rotating shaft of the turntable is fixed on the box body; the box body is also provided with a box cover, and the box cover is fixed below the box body; namely, the opening direction of the box body is downward, so that the erosion of rain and snow can be avoided.
The secondary transmission pull rods 4 are symmetrically arranged, and a symmetrical axis is a straight line L which passes through the circle center of the crank arm 1 and is parallel to the alternate connecting rods; correspondingly, the alternate connecting rods are also symmetrically arranged.
The rotary tables are in three pairs, the insulating terminals are arranged on the rotary tables, and the insulating terminals of each pair of rotary tables are respectively provided with a static contact and a moving contact.
The principle of the utility model is that: the crank arm 1 is driven to rotate manually or by a motor, the touch pulley is driven to move back and forth on the slide rail through the primary transmission pull rod, and the secondary transmission pull rod is connected with the touch pulley in a shaft manner, so that the touch pulley moves to drive the alternate connecting rods to move back and forth through the secondary transmission pull rod, and the two-phase connecting rods move to drive the rotary table to rotate through the linkage crank arm; because the static contact and the moving contact are respectively arranged on the pair of turntables, the static contact and the moving contact can be driven to be coincided and disconnected through the rotation of the turntables.
