Description

Technical Field

[0001] The utility model relates to the technical field of three-phase asynchronous motors, in particular to a waterproof three-phase asynchronous motor. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is widely used, especially in industrial production, where it has an irreplaceable position. A three-phase asynchronous motor is a type of electric motor that is powered by a 380V three-phase AC power supply (with a phase difference of 120 degrees). Since the rotor and stator rotating magnetic fields of a three-phase asynchronous motor rotate in the same direction but at different speeds, there is a slip rate, so it is called a three-phase asynchronous motor.

[0003] The bottom of the three-phase asynchronous motor in the prior art is usually equipped with a disassembly cover to facilitate the staff to disassemble it and inspect the inside of the three-phase asynchronous motor. However, the existing disassembly cover is usually fixedly connected to the three-phase asynchronous motor by multiple screws or bolts, which wastes a lot of time during disassembly and reduces the inspection rate. For this reason, we propose a waterproof three-phase asynchronous motor. Utility Model Content

[0004] The utility model provides a waterproof three-phase asynchronous motor, which solves the technical problems raised by the background technology in the prior art.

[0005] The utility model solves the above-mentioned technical problem as follows: it comprises a three-phase asynchronous motor body, a mounting ring is fixedly connected to the bottom end of the three-phase asynchronous motor body, an annular sealing groove is provided on the surface of the mounting ring, an annular sealing plate is sleeved and connected inside the annular sealing groove, a disassembly cover is fixedly connected to the surface of the annular sealing plate, a rubber sealing plate sleeved and connected to the inside of the mounting ring is fixedly connected to one side of the disassembly cover, four fixing blocks evenly distributed in a circumference are fixedly connected to the outer end surface of the mounting ring, a slot is provided on the surface of the fixing block, a plug plate is slidably connected inside the slot, the plug plate is fixedly connected to the surface of the disassembly cover, a card slot is provided on the upper end surface of each plug plate, and each of the plug plates is connected to the corresponding fixing block through a positioning mechanism.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, a plurality of heat sinks evenly distributed in a circumference are fixedly connected to the surface of the three-phase asynchronous motor body.

[0008] Furthermore, the positioning mechanism includes an inverted U-shaped frame fixedly connected to the surface of the fixing block.

[0009] Furthermore, a movable plate is arranged inside the inverted U-shaped frame, and one side of the movable plate is fixedly connected to a positioning card plate which is slidably connected to the inside of the corresponding card slot.

[0010] Furthermore, a moving screw rod is provided on the other side of the moving plate and is rotatably connected to the moving plate via a bearing. The moving screw rod penetrates the inverted U-shaped frame and is threadedly connected to the penetrating portion.

[0011] Furthermore, one end of the movable screw is fixedly connected to a rotating cap, and both side surfaces inside the inverted U-shaped frame are provided with limiting sliding grooves, and the limiting sliding grooves are slidably connected to a limiting sliding block fixedly connected to the movable plate.

[0012] The beneficial effects of the utility model are as follows: the utility model provides a waterproof three-phase asynchronous motor, which has the following advantages:

[0013] Through the cooperation between the disassembly cover, the mounting ring, the fixing block, the slot, the plug plate, the card slot, the positioning mechanism, the annular sealing groove, the annular sealing plate and the rubber sealing plate, it is convenient for the staff to disassemble the disassembly cover, so that it is convenient for the staff to quickly inspect and repair the inside of the three-phase asynchronous motor body.
