Description

Technical Field

[0001] The utility model relates to the technical field of motor rainproof covers, and more specifically, to a motor rainproof cover. Background Art

[0002] Electric motors are widely used power equipment in modern industrial production. They can convert electrical energy into mechanical energy and drive various mechanical equipment to operate. However, during use, electric motors are often affected by the external environment. Especially in outdoor or humid environments, electric motors are easily eroded by rain, water vapor, dust, etc., resulting in reduced insulation performance, coil heating, bearing corrosion, and other problems, which seriously affect the service life and reliability of the motor. In order to protect the motor from environmental factors, it is usually necessary to install a rain cover on the outside of the motor. A rain cover is a shell specially designed for motor protection. It can isolate the motor from the external environment and prevent rain, water vapor, dust, etc. from entering the motor. It also has a certain heat dissipation function and can promote the discharge of heat inside the motor. However, due to the diversity of motor models and specifications, different models of motors need to be equipped with rain covers of different sizes and shapes. If the rain cover does not match the motor model, it is difficult to achieve a good protection effect, and it may even affect the normal operation of the motor. Therefore, how to quickly, conveniently and reliably install and fix the rain cover according to the motor model is one of the key technologies for motor protection.

[0003] At present, most of the common motor rain covers on the market use bolted connections to fix the rain covers to the motor housing. Although this fixing method is simple and easy, it has many shortcomings in practical applications. First, bolted connections require the use of tools, such as wrenches and screwdrivers, which are time-consuming and laborious to install and remove. Especially when working in a small space, the operation is inconvenient and the tools are easy to drop, which poses a safety hazard. Secondly, the reliability and stability of bolted connections are poor. During the operation of the motor, the bolts are easily loosened and fall off due to factors such as vibration and impact, resulting in a gap between the rain cover and the motor, and the protection function is lost.
