Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical equipment, in particular to a protection device. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy and has wide and important applications in modern industry and daily life. The working principle of the motor is based on the laws of electromagnetic induction and Ampere's force law. Through the force generated by the current in the magnetic field, the rotor of the motor rotates, thereby outputting mechanical energy. As a common driving tool in daily life, the motor is widely used in various fields, including construction sites full of dust or the interior of mine shafts that are easily impacted by gravel, etc., which are harsh environments.

[0003] The "motor protection device" disclosed in the patent publication number "CN221282932U" includes a box body and a motor main body. Shock-absorbing mechanisms for reducing the impact force of the motor main body are arranged at the four corners of the bottom of the box body. A dust-proof mechanism for preventing the dust-proof net from being blocked is arranged on the right side inside the box body. An anti-detachment mechanism for preventing the joint wire from detaching is arranged on the right side of the top of the motor main body. Fixing plates are fixedly connected to the front and rear ends on the right side of the top of the box body. Two connecting shafts are fixedly connected to the adjacent sides of the two fixing plates. The outer wall of the right connecting shaft is rotatably connected with a cover plate. In this motor protection device, through the setting of the dust-proof mechanism, the motor main body can always maintain good heat dissipation. At the same time, under the protection of the box body, the motor main body will not be impacted by gravel or affected by dust during normal operation. Through the setting of the anti-detachment mechanism, the socket of the motor main body is prevented from detaching from the joint, ensuring its normal use.

[0004] In view of the above related problems, when protecting the motor, the motor is placed inside the box body for protection. When the motor is in use, it needs to be fixed on the lower bracket through the motor base. When protecting through the box body, an additional fixing device needs to be set to fix the external protection box body, and the design of the box body will affect the air exchange rate inside and outside, thereby affecting the heat dissipation effect of the motor.

[0005] Therefore, the utility model provides a protection device to solve the above problems. Summary of the Utility Model
