Technical Field

[0001] This utility model relates to the field of isolation knife drive shaft technology, specifically an embedded anti-displacement isolation knife drive shaft. Background Technology

[0002] In power systems, isolating switches, as crucial primary equipment, are widely used in substations, distribution rooms, and other locations. They are primarily used for power isolation, switching operations, and ensuring reliable isolation between electrical equipment and live parts during maintenance. They are key devices for ensuring the safe and stable operation of power systems. The normal operation of the isolating switch relies on the effective transmission of a drive shaft, which is responsible for transmitting power from the operating mechanism to the isolating switch contacts, realizing opening and closing operations. With the increasing demands for intelligence and reliability in power systems, higher standards are being placed on the performance of the isolating switch drive shaft. Existing isolating switch drive shafts have the following problems:

[0003] The current isolation knife drive shaft has high structural strength and low installation requirements. The mounting bottom plane of the isolation knife drive shaft is a single plane. During the operation of the equipment, a large vibration force is generated, which can easily cause the isolation knife drive shaft to shift.

[0004] Therefore, we propose an embedded anti-displacement isolation knife drive shaft to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide an embedded anti-displacement isolation knife drive shaft to solve the problems mentioned in the background art, such as the high structural strength, low installation requirements, and the fact that the mounting bottom plane of the isolation knife drive shaft is a whole plane, which generates a large vibration force during the operation of the equipment, thus easily causing the isolation knife drive shaft to shift.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an embedded anti-displacement isolation knife drive shaft, including a mounting base plate, on the upper left and right sides of the mounting base plate, a first bearing seat is installed, and an isolation knife drive shaft body is installed between the first bearing seats. The upper surface of the mounting base plate is provided with a first groove and a second groove from left to right, and a first limiting bearing and a second limiting bearing are respectively installed on the first groove and the second groove.

[0007] An isolation knife mounting block is installed on the isolation knife drive shaft body, and an adjusting bolt is installed on the isolation knife mounting block. A first bevel gear is installed on the isolation knife drive shaft body. A second bearing seat is installed on the rear side of the mounting base plate, and a rotating shaft is installed on the second bearing seat. A second bevel gear is installed on the end of the rotating shaft near the first bevel gear.

[0008] Preferably, the first groove and the second groove are respectively provided with a first threaded hole and a second threaded hole, the first groove and the second groove are of equal depth, and the upper surface of the mounting base is provided with mounting holes, and multiple mounting holes are provided.

[0009] With the above structural design, multiple mounting holes facilitate the installation of the device on the equipment, enhancing versatility; the first and second grooves enable the embedded installation of the first and second limit bearings, improving stability and ensuring the stability of the isolation knife drive shaft body during installation and operation.

[0010] Preferably, the isolation knife drive shaft body passes through the first limit bearing and the second limit bearing, and the first limit bearing and the second limit bearing are respectively equipped with a first fastening bolt and a second fastening bolt, which are respectively connected to the first threaded hole and the second threaded hole on the first groove and the second groove.

[0011] The above structural design improves the stability of the isolation knife drive shaft body during installation and operation, ensuring the accuracy and reliability of isolation knife operation.

[0012] Preferably, multiple isolation knife mounting blocks are provided, and the isolation knife mounting blocks are sleeved on the isolation knife drive shaft body.

[0013] With the above structural design, when the isolating knife drive shaft rotates, multiple isolating knife mounting blocks can simultaneously drive multiple isolating knives to move, meeting the requirements of different power systems for the number of isolating knives, improving the practicality of the equipment, and facilitating large-scale opening and closing operations.

[0014] Preferably, an isolation blade is mounted on the isolation blade mounting block, and an adjusting bolt is threadedly connected to the isolation blade mounting block.

[0015] With the above structural design, the position of the isolation knife mounting block can be flexibly adjusted on the isolation knife drive shaft body to meet the precise adjustment requirements of the isolation knife position under different working scenarios. After adjustment, it is fixed by adjusting bolts to ensure the stability and accuracy of the isolation knife during operation.

[0016] Preferably, the rotating shaft is connected to the output shaft end of the motor, and the second bevel gear is fixedly connected to the rotating shaft.

[0017] The above structural design ensures that the motor's power can be stably transmitted to the second bevel gear, providing a stable power source for subsequently driving the first bevel gear and the isolation blade drive shaft body to rotate, ensuring the reliability of power transmission, and reducing energy loss and the probability of failure during power transmission.

[0018] Preferably, the second bevel gear is perpendicular to and meshes with the first bevel gear, and the first bevel gear is fixedly connected to the isolation knife drive shaft body.

[0021] Significant anti-displacement effect: Through the synergistic action of the first groove, the second groove, the first limit bearing, the second limit bearing, the first fastening bolt, and the second fastening bolt, the displacement of the isolation knife drive shaft body during operation is effectively limited. Compared with the traditional drive shaft with integral flat mounting, the stability of the drive shaft is greatly improved, ensuring the accuracy and reliability of the isolation knife operation and enhancing the safety of power system operation.

[0022] Stable power transmission: The vertical meshing transmission between the second bevel gear and the first bevel gear, combined with the connection between the rotating shaft and the motor output shaft, can stably transmit the motor's power to the isolating knife transmission shaft body, ensuring that the isolating knife operates smoothly and reliably during opening and closing operations, and reducing the probability of failures caused by unstable power transmission.

[0023] The structure is reasonably designed: multiple isolating knife mounting blocks are sleeved on the isolating knife drive shaft body, and multiple isolating knives can be installed according to actual needs. At the same time, the position of the isolating knife mounting blocks can be adjusted to meet the usage requirements of different power systems and improve the practicality of the equipment.
