[0026] The main body 1 also includes a protective shell 103, a ventilation window 104, a fixed plate 105, an electric motor 106 and a dust removal brush 107. The protective shell 103 is fixedly mounted on the upper end of the fixed base plate 101, the protective shell 103 is located on the outside of the worm gear reducer body 102, and the transmission end of the front end of the worm gear reducer body 102 extends to the front of the protective shell 103.

At the transmission end, the dust removal brush 107 is movably connected with the ventilation window 104. When the protective structure is protecting the worm gear reducer body 102, the worm gear reducer body 102 generates heat, and the ventilation window 104 promotes air convection, so that the heat inside the protective shell 103 is exchanged with the external air. During the input of external air, the ventilation window 104 filters the dust and impurities in the air, so that the dust and impurities adhere to the surface of the ventilation window 104, and the electric motor 106 drives the dust removal brush 107 to rotate, so as to clean the dust and impurities attached to the ventilation window 104, thereby ensuring the normal ventilation and heat dissipation operation of the protective structure.

[0027] The protection mechanism 2 includes a control panel 201, which is fixedly mounted at the front end of the protection shell 103. The protection mechanism 2 also includes a temperature sensor 202 and a mounting bracket 203. The temperature sensor 202 is fixedly mounted at the rear end inside the protection shell 103.

The protection mechanism 2 also includes a support plate 206, which is fixedly mounted at the left end of the inner end of the mounting bracket 203. The left end of the screw 205 is rotatably connected to the support plate 206. The protection mechanism 2 also includes a threaded sleeve 207 and a ventilation fan 208.

The temperature sensor 202 monitors the internal temperature of the protective shell 103 in real time and uploads the data to the control panel 201. When it senses that the internal temperature of the protective shell 103 is too high, the ventilation fan 208 is started to dissipate heat for the worm gear reducer body 102. At the same time, the driving motor 204 works to drive the threaded sleeve 207 to move on the screw 205. The threaded sleeve 207 drives the ventilation fan 208 to move at a uniform speed, so as to evenly dissipate heat for the worm gear reducer body 102 and accelerate the heat dissipation through the ventilation window 104.

[0028] Working principle: When the protective structure is protecting the worm gear reducer body 102, the worm gear reducer body 102 generates heat, and the ventilation window 104 promotes air convection, so that the heat inside the protective shell 103 is exchanged with the external air. The temperature sensor 202 monitors the internal temperature of the protective shell 103 in real time and uploads the data to the control panel 201. When it senses that the temperature inside the protective shell 103 is too high, the ventilation fan 208 is started to dissipate the heat of the worm gear reducer body 102, and the motor 204 is driven at the same time. The work drives the threaded sleeve 207 to move on the screw 205, and the threaded sleeve 207 drives the ventilation fan 208 to move at a constant speed, so as to evenly dissipate the heat of the worm gear reducer body 102, and accelerate the heat dissipation through the ventilation window 104. During the input of external gas, the ventilation window 104 filters the dust and impurities in the air, so that the dust and impurities adhere to the surface of the ventilation window 104, and the electric motor 106 drives the dust removal brush 107 to rotate, so as to clean the dust and impurities attached to the ventilation window 104, and ensure the normal ventilation and heat dissipation operation of the protective structure.
