[0002] As a power output device, electric motors play an irreplaceable role in the development of modern automatic mechanization and are used in various fields.

[0003] Electric motors will also be used in some complex environments, such as underwater, high temperature environment, corrosive environment, etc. At this time, it is necessary to improve the structure of the motor itself and perform external protection to increase the service life of the motor. In a smoke corrosion environment, the motor needs to adopt external protection measures to isolate the smoke and prevent it from entering the motor and corroding the motor. It is also necessary to avoid corrosion of the motor casing. The existing protection measures generally use a casing to cover the outside of the motor for physical isolation. However, there are the following problems that need to be solved: First, the heat dissipation problem of the motor. The all-round wrapping of the casing hinders the diffusion of heat and affects the life of the motor; second, in addition to the use of magnetic transmission, even if the casing is installed, the output shaft of the motor still needs to pass through the casing, so there is a risk of smoke entering;

[0004] In the prior art, the protection of the motor in a smoke-corrosive environment has problems of poor heat dissipation and inadequate protection. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a smoke corrosion resistant motor in view of the above-mentioned technical deficiencies, which solves the problems of poor heat dissipation and inadequate protection of the motor in a smoke corrosion environment.

[0009] A cooling device is arranged in the bellows and is used for cooling the inside of the bellows.

[0010] To further optimize the technical solution, the cooling device includes a cooling plate, the cooling plate is directly opposite to the air inlet pipe, and the cooling plate is located between the air inlet pipe and the air outlet.

[0011] To further optimize the technical solution, a side of the circumferential side wall of the casing close to the fixing plate is provided with a drain pipe, the drain pipe is located at the lower side of the casing, and further comprises:

[0012] A water collecting box is arranged at the lower side of the drain pipe, and a drain outlet is provided at the lower part of the water collecting box;

[0013] An end cap is arranged at the lower side of the water collecting box and is used to block the drain outlet.

[0014] Further optimizing the technical solution, one side of the fixing plate has a sleeve, the sleeve is connected to the through hole, and the inner diameter of the sleeve is larger than the diameter of the through hole; and further comprising:

[0015] A mounting plate, disposed on the fixing plate and located outside the casing;

[0016] A brush is arranged on the mounting plate, and a tip of the brush abuts against the output shaft.

[0037] like Figure 1-9 As shown, a smoke corrosion-resistant motor includes a motor body 1, and the motor body 1 has an output shaft 101; it also includes: a casing 2, which is sleeved outside the motor body 1, and along the axial direction of the casing 2, the casing 2 has a fixing plate 201 on one side and an opening 202 on the other side, the fixing plate 201 has a through hole 2011, the output shaft 101 passes through the through hole 2011, and an exhaust interval 2012 is provided between the inner wall of the through hole 2011 and the output shaft 101; a bellows 3, which is arranged at the opening 202 and is used to block the opening 202, and the bellows 3 has a plurality of air outlets 301 on the side opposite to the motor body 1, and an air inlet pipe 302 on one side of the bellows 3, and the air inlet pipe 302 is used to communicate with an external air supply device; a cooling device 4, which is arranged in the bellows 3 and is used to cool the bellows 3.

[0038] When in use, the casing 2 and the bellows 3 form a sealed environment, the fixing plate 201 and the bellows 3 are opposite to each other on the left and right, the motor body 1 is fixedly mounted on the fixing plate 201 or fixedly connected to the inner wall of the casing 2, the output shaft 101 passes through the through hole 2011, and the air outlet 301 of the bellows 3 blows high-pressure gas into the casing 2 to maintain a higher air pressure environment inside the casing 2 than outside, and blows air to the outside through the exhaust gap 2012 to make the internal gas flow, which can effectively prevent smoke from entering the casing 2 from the exhaust gap 2012.

[0039] The bellows 3 is connected to the gas outlet of the external gas supply device, and the external gas supply device can provide high-pressure gas after filtering and processing by the existing equipment. The external device can be located outside the smoke corrosion environment and supply gas through the pipeline.

[0040] The cooling device 4 is a prior art, which can cool the air, improve the effect of the gas flow in the casing 2 on cooling the motor body 1, and solve the problem of the motor body 1 heating up too high and too fast in the closed protection state in the prior art.

[0041] Conventional sealing treatment can be performed between the bellows 3 and the opening 202 of the casing 2, such as adding a rubber pad, etc., to reduce air leakage.

[0042] Furthermore, the cooling device 4 includes a cooling plate 401 , which is directly opposite to the air inlet pipe 302 , and is located between the air inlet pipe 302 and the air outlet 301 .

[0043] When in use, the cooling device 4 may include a cooling plate 401, inside which refrigerant or the like can flow, and the cooling plate 401 is directly opposite to the air inlet pipe 302, so as to be in full contact with the gas entering the bellows 3, and to prevent the gas from being directly discharged from the air outlet 301 after entering the bellows 3, thereby providing a good cooling effect and making the air outlet 301 emit more evenly.

[0045] When in use, the gas provided by the external gas supply device can be dehumidified to reduce water vapor, and the drain pipe 203 can be set to discharge the residual water vapor to reduce the residue in the casing 2. The drain pipe 203 can be located at the lower side of the side wall of the casing 2013, which is convenient for collecting water droplets, and enters the water collection box 2031 through the drain pipe 203 for temporary storage, and can be discharged to the outside by opening the end cap 2033, and the end cap 2033 can be threadedly connected with the drain port 2032 of the water collection box 2031.

[0048] When in use, the brush 501 can clean the portion of the output shaft 101 outside the casing 2 near the through hole 2011 to reduce the accumulation of smoke and dust. After the smoke and dust accumulate on the output shaft 101 at the exhaust interval 2012, it will affect the gas exhaust route and gradually accumulate inside the casing 2, causing adverse consequences. The gas exhausted from the exhaust interval 2012 can blow off the impurities on the brush 501, so that the brush 501 can be self-cleaning.

[0049] Furthermore, the mounting plate 5 is semi-circular, and has two mounting plates 5 . The two semi-circular mounting plates 5 are connected to form an embracing structure, and the embracing structure is sleeved on the sleeve 2013 . A brush 501 is provided on each mounting plate 5 .
