Description

Technical Field

[0001] The utility model relates to the technical field of grounding switches for ring network cabinets, in particular to a grounding switch locking device for ring network cabinets. Background Art

[0002] The grounding switch locking device of the ring main unit is a key component to ensure the safe and stable operation of the power system. In the power distribution system, the ring main unit plays the role of distributing current, monitoring line status and providing protection functions, and the grounding switch locking device is one of the important guarantees for the safe operation of the ring main unit;

[0003] When the ring main unit grounding switch is in use, the staff is required to use an external rod structure to connect to the rotating shaft of the grounding switch. At this time, the closing action trajectory is an arc-shaped swing trajectory, requiring the staff to accurately control the movement trajectory and force of the rod during operation, which increases the complexity of the operation. This may make it difficult for unskilled staff to accurately perform the closing operation, and may even damage the grounding switch or cause a safety accident due to misoperation. In addition, the staff is required to spend more time and energy to ensure the accuracy of the operation, which reduces the operating efficiency. Therefore, corresponding improvements are needed. Utility Model Content

[0004] The utility model aims to provide a ring main unit grounding switch locking device to solve the problems of the existing ring main unit grounding switch locking device in the above background technology that the operation is complicated and the user comfort is not high.

[0005] To achieve the above object, the utility model provides the following technical solution: a ring main unit grounding switch locking device, comprising a grounding switch body and a main shaft, wherein one side of the grounding switch body is connected to the main shaft;

[0006] Also includes:

[0007] One side of the grounding switch body is connected to a T-seat, and one side of the T-seat is connected to a rear support, one side of the rear support is connected to a vertical bearing seat, and the interior of the vertical bearing seat is connected to a locking shaft, and one end of the locking shaft is connected to a swing arm, one side of the swing arm is provided with a connecting rod deflection structure, and the other side of the swing arm is connected to a double-joint connecting rod;

[0008] One side of the T-shaped seat is connected with a convex seat, and one side of the convex seat is connected with a supporting column, and a sliding driving member is arranged on the outer side of the supporting column.

[0009] When using the ring network cabinet grounding switch locking device of the present technical solution, the traditional bending method of the ring network grounding switch can be changed to a horizontal pushing method for locking through the setting of the sliding drive part and the connecting rod deflection structure, which is more convenient and has high operating comfort.

[0010] Preferably, the vertical bearing seat is detachably connected to one side of the rear support by bolts.

[0011] Preferably, the sliding drive member includes a sliding tongue sleeved on the outer side of the support column, and the other side of the sliding tongue is connected to a guide rod, and one end of the guide rod passes through the convex seat.

[0012] Preferably, one side of the sliding tongue is connected to a movable sleeve, one side of the movable sleeve is connected to an L-shaped bracket, and one side of the L-shaped bracket is connected to a supporting shaft.

[0013] Preferably, one end of the double-joint connecting rod is sleeved on a support shaft on one side of the sliding tongue, the double-joint connecting rod is movably connected to the sliding tongue, and the other end of the double-joint connecting rod is movably connected to the lower end of the swing arm.

[0014] Preferably, the connecting rod deflection structure includes a main connecting rod movably connected to the upper end of the swing arm, and one end of the main connecting rod is connected to a secondary joint, and one end of the secondary joint is sleeved on the outside of the main shaft.

[0015] Preferably, the main connecting rod and the auxiliary joint are movably connected via a short shaft.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the ring network cabinet grounding switch locking device is easy to use and has a good labor-saving effect;

[0017] The sliding tongue is pushed manually to slide on the support column. During the sliding process of the sliding drive member on the support column, the double-joint connecting rod is pushed to move synchronously. Since one end of the double-joint connecting rod is movably connected to the bottom end of the swing arm, the swing arm can be pushed to flip around the locking axis, so that the upper end of the swing arm is flipped to the other side, and the main connecting rod is pushed to move forward. By utilizing the cooperation of the main connecting rod and the auxiliary joint, the auxiliary joint can be pushed to move to the same side, so that the auxiliary joint pushes the main shaft to flip, and the grounding switch body can be powered off. The operation is convenient, and the horizontal movement of the sliding tongue is converted into the rotational movement of the main shaft, that is, the closing is a horizontal movement trajectory, which replaces the traditional arc curve swing trajectory generated by the up and down bending to achieve power on or off. The operation precision requirement is low, the operation is more convenient and labor-saving, and compared with the traditional bending method, it can reduce the wear on the hand;

[0018] During the movement of the sliding drive, the guide rod is used for limit guiding to ensure the stability of the movement of the sliding drive. When the sliding tongue stops being pushed later, the spring on the grounding switch body is used to reset the grounding switch body, thereby pushing the grounding switch body to reset, and the grounding switch body can be smoothly connected to the power supply. The operation is convenient and the overall use is labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS
