Referring to fig. 5, when the ventilation hole 3 on the fan housing 2 is blocked due to the field environment, long-term operation, etc., the hot air emitted from the heat dissipating device at the rear end of the permanent magnet motor cannot well come out of the ventilation hole 3, so as to affect the heat dissipation of the motor, at this time, due to the blocking of the ventilation hole 3, the wind inside will come out from the gap at the connection position of the fan housing 2 and the motor body 1, and because the gap is smaller, a larger pressure will be generated inside the fan housing 2, when the pressure reaches a certain degree, the air in the fan housing 2 will form a pressure on the surface of the sealing block 44, so as to push the sealing block 44 to shrink the pressure spring 42, during this process, the sealing block 44 and the baffle 43 retract together, and the pressure spring 42 is compressed, in order to ensure that the baffle 43 and the sealing block 44 move in parallel in the axial direction inside the outer fixing member 40, in this embodiment, a positioning strip 48 is fixedly arranged on the inner wall of the outer fixing member 40, and a positioning groove matched with the positioning strip 48 is arranged on the baffle 43. When the sealing block 44 is retracted outside the annular stop member 47, pressurized gas in the fan housing 2 is ejected from the through hole in the middle of the outer fixing member 40 via the inner fastening member 46; at this time, the field staff can judge whether the pressure in the fan cover 2 is too high by judging whether the air is sprayed out of the outer fixing piece 40 by hand, if the air is sprayed out, the air is proved to be too high in the pressure in the fan cover 2, and if the air is sprayed out, the air exchanging hole 3 is proved to be blocked, or the fan power is too high, or the rotating speed of the permanent magnet motor is too high.
It should be noted that, a gap is provided between the baffle 43 and the inner fastening member 46 for the flow of the gas, and in some embodiments, a plurality of ventilation holes are provided in the baffle 43.
In some embodiments, in order to make the monitoring more intuitive, a warning rod 45 is fixedly arranged in the middle of one side of the baffle 43 fixedly connected with the pressure spring 42, the warning rod 45 passes through the middle of the pressure spring 42, and a through hole capable of passing through the warning rod 45 is formed in the radial direction of the warning rod 45 by the outer fixing piece 40; the field personnel can judge by judging whether the warning lever 45 protrudes.

The principle is that the inner space of the fan cover 2 is limited, the connecting parts between every two air exchanging holes 31 in the prior art have larger sectional areas in the fan cover 2, when the air in the fan cover 2 is blown out of the fan cover 2 under the action of the fan, larger resistance is encountered, heat exchange is hindered, meanwhile, the current of the fan is increased, and when the fan is not used for radiating, and fan blades are added on a motor bearing for radiating, the current of the motor is increased, and the radiating effect is influenced; the present embodiment solves this technical problem by forming the sharp portion 32 between the inside ventilation holes 31 of the stroke cover 2 in pairs.
Referring to fig. 8, in some embodiments, the ventilation holes 3 include an outer ventilation hole 30 located outside the fan housing 2 and an inner ventilation hole 31 located inside the fan housing 2, where a ventilation channel with a truncated cone structure is formed between the outer ventilation hole 30 and the inner ventilation hole 31, so as to prevent the ventilation hole 30 from being blocked and promote the exchange of air inside and outside the fan housing 2, as described above.
Referring to fig. 4 and 5, in some embodiments, for installation and use convenience, a sleeve 41 is fixedly arranged on one side of the outer fastening member 40 close to the inner fastening member 46, and the sleeve 41 is fixedly sleeved in the inner fastening member 46; the sleeve 41 is fixedly arranged on one side, close to the inner fastening piece 46, of the outer fastening piece 40, an inner thread is arranged in the sleeve 41, and the inner fastening piece 46 is in threaded connection with the sleeve 41 through an outer thread on the outer part.
The structural design of the permanent magnet motor air exchanging port with the heat radiation warning function reduces the resistance of hot air from the inside of the fan cover to the outside of the fan cover, has high heat radiation efficiency and is not easy to block; and on-site personnel can intuitively judge whether a fan cover air exchange port of the permanent magnet motor is blocked or not by checking whether the unidirectional air outlet device is provided with air outlet or whether a warning rod is provided with the air outlet or not, and can also judge whether the power of the motor heat dissipation fan or the fan blade size of the motor is suitable or not, because when the power of the motor heat dissipation fan is overlarge or the fan blade size of the motor is overlarge, the pressure inside the fan cover 2 is increased, and although the joint of the fan cover and the motor still exists in a gap communicated with the outside air, when the power of the motor heat dissipation fan is overlarge or the fan blade size of the motor is overlarge, the pressure inside the fan cover 2 is still increased, and when the pressure inside the fan cover 2 cannot be discharged to the outside through the air exchange hole 31 in time, the unidirectional air outlet device 4 is provided with the air outlet or the warning rod 45 is provided with the air outlet.
The above is only a preferred embodiment of the present application, and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art.
