Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor for preventing sparks. Background Art

[0002] Spark-proof motors are specially designed motors that are designed to reduce or avoid sparks during operation. Such motors are often used in potentially flammable or explosive environments, such as chemical plants, oil and gas extraction sites, tankers, refineries, etc. In these places, even tiny sparks can cause serious accidents, so special precautions need to be taken.

[0003] The patent with announcement number CN214337687U discloses a motor device for preventing sparks, which includes a mounting plate, a motor body, a protective cover and a mounting shell. The mounting plate is arranged as a rectangular plate structure, a protective cover is fixed to the top of the mounting plate by multiple sets of bolts, and a motor body is arranged inside the protective cover, and the output end of the motor body passes through a through hole provided in the outer wall of the protective cover and extends to the outside of the protective cover. The device; the fireproof layer provided has a good fire-blocking effect, the sound insulation layer reduces the transmission of the noise generated by the motor body to the outside, and the breathable waterproof layer has an effective waterproof effect; by pressing the card rod, the card rod drives the compression spring to compress, so that the card hook is disengaged from the card rod, The invention is convenient for installing and disassembling the motor body, but the device has the problem that the mounting plate is fixed at the required position by bolts, and then the motor body is fixed to the fixing seat by bolts, and then the fixing seat is fixed to the mounting plate by hooks and rods, and then the motor is wrapped and protected by a protective cover, but the motor device for spark prevention lacks a heat dissipation mechanism for the motor body inside the protective cover. Even if the protective cover has a certain air permeability, if the outside of the protective cover is covered by dust in the air, it will also affect the heat dissipation effect of the device, thereby affecting the normal operation of the fire-proof motor. Therefore, a motor for spark prevention is proposed to solve the problem that the existing spark-proof motor device has poor heat dissipation effect and affects the operation of the motor.
