Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor technology and relates to a three-phase asynchronous motor. Background Technology
[0002] With the development of technology, motors are used in every household to improve the convenience of life. As a result, many motors are used in outdoor settings. To protect the motors, a protective platform is built to prevent rainwater from corroding them. However, most platforms are built with bricks and covered with cloth to form a simple protective platform. But in actual use, when the rain is too heavy or lasts for a long time, the rainwater can still seep into the platform and come into contact with the motor, which may cause damage to the motor. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing a three-phase asynchronous motor that reduces liquid contact.
[0004] The objective of this utility model can be achieved through the following technical solution: A three-phase asynchronous motor, comprising an assembly housing and a motor body connected to the assembly housing, characterized in that a protective component connected to and used to protect the motor body is provided on the wall surface of the assembly housing located at the motor body, the protective component comprising a connecting unit connected to the assembly housing and a flow guiding unit connected to the connecting unit and used for liquid flow guiding, the connecting unit comprising a connecting shell with a U-shaped structure, and the connecting shell being connected to the assembly housing through a flange portion, the flow guiding unit comprising two flow guiding strips connected to the connecting shell.
[0005] In the aforementioned three-phase asynchronous motor, a sealing gasket is provided between the connecting shell and the mounting shell to enhance the sealing performance.
[0006] In the aforementioned three-phase asynchronous motor, the guide strip is arranged in an L-shape, with two guide strips respectively located on both sides of the connecting shell and connected thereto. The length of the guide strip is greater than the length of the connecting shell, and the upper end face of the guide strip is inclined.
[0007] In the aforementioned three-phase asynchronous motor, the connecting shell is provided with a sealing plate at its outer end, which is slidably fitted therewith and has an L-shaped structure. The two inner walls of the connecting shell are provided with protruding strips that are connected to the sealing plate and slidably installed therewith.
[0008] In the aforementioned three-phase asynchronous motor, a support base connected to the upper end surface of the sealing plate and used to support the motor body is provided, and a support foot connected to the lower end surface of the sealing plate and used to support the sealing plate is provided.
[0009] Compared with existing technologies, this three-phase asynchronous motor isolates the liquid from contact with the motor by setting up protective components. Attached Figure Description
