[0035] In order for those skilled in the art to better understand the application, the technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the application.

[0036] As Figures 1-2 shown, the application provides a motor protection structure, comprising a body 4, an output shaft 42 of the motor, and a protective shell for protecting the body 4, which can be disassembled, the protective shell comprising a lower shell 1 and an upper shell 2 spliced together, and the lower shell 1 and the upper shell 2 are cooperatively installed;

[0037] The lower shell 1 has a bottom plate 11 arranged in a rectangular shape, both sides of the upper end of the bottom plate 11 are fixedly installed with a protective plate 12, and one side end of the protective plate 12 is fixedly installed with a front plate 13, the front plate 13 is provided with a mounting hole 14, and the mounting hole 14 is matched with the output shaft 42, so that when the body 4 is installed in the protective shell, the output shaft 42 is inserted into the mounting hole 14.

[0038] In order to fix the body 4, both sides of the lower end of the body 4 are provided with a fixed ring 41 with a hole, and an installation plate 15 is fixedly installed on the upper end of the bottom plate 11 through a vertical rod, the installation plate 15 is provided with a fixing hole (not marked in the figure) matched with the fixed ring 41, and it should be noted that when the body 4 is placed on the installation plate 15, the output shaft 42 and the mounting hole 14 are on the same axis, so when the body 4 is installed, first place the body 4 on the installation plate 15, then insert the output shaft 42 into the mounting hole 14, then align the fixing hole on the installation plate 15 with the fixed ring 41, then fix it through the bolt, so as to ensure the stability of the body 4 during use.

[0039] The upper shell 2 has a cover plate 21 above the protective plate 12, and a side plate 22 fixedly installed below the cover plate 21, the side plate 22 is arranged opposite to the front plate 13, in order to splice and fix the upper shell 2 and the lower shell 1, the upper end surface and the side end surface of the protective plate 12 are provided with a matching groove 16, and a matching strip 23 is fixedly installed on the lower end of the cover plate 21 and the inner end of the side plate 22, the matching strip 23 and the matching groove 16 are matched with each other, so that after the body 4 is installed in the lower shell 1, the matching strip 23 on the upper shell 2 is directly clamped into the matching groove 16, thereby cooperatively fixing the upper shell 2 and the lower shell 1;

[0040] In the application, threaded holes can also be provided at the matching ends of the upper shell 2 and the lower shell 1, and after the upper shell 2 and the lower shell 1 are assembled, they can be fixed by bolts.

[0041] In order to ensure the ventilation effect of the protective shell, a plurality of ventilation grooves 17 are provided on the protective plate 12, and the ventilation grooves 17 on the two protective plates 12 correspond to each other, and in the application, the ventilation grooves 17 are arranged obliquely, so that the air flow can be better guided, the resistance can be reduced, and the ventilation efficiency can be improved;

[0042] At the same time, a mounting groove 18 is also provided in the mating groove 16. The width of the mounting groove 18 is smaller than that of the mating groove 16. A filter plate 3 is installed inside the mounting groove 18. In this application, the height of the filter plate 3 is greater than the height of the ventilation groove 17 and less than the depth of the mounting groove 18. Therefore, when the filter plate 3 is placed in the mounting groove 18, the ventilation groove 17 can be completely blocked without affecting the installation of the upper shell 2.

[0043] A handle 31 is fixedly mounted on the upper end of the filter plate 3 , and the filter plate 3 can be easily taken out, replaced, and cleaned through the handle 31 .

[0044] like Figures 3-4 As shown, in order to drain water droplets or accumulated water in the protective shell, the upper end of the bottom plate 11 is configured as a curved surface with a higher middle and lower sides, and water storage grooves 111 are opened at both ends of the bottom plate 11 near the protective plate 12. The lower end of the water storage groove 111 is inclined to open a channel 112, and the width of the channel 112 is smaller than the width of the water storage groove 111;

[0045] At the same time, a drainage mechanism 5 is provided in the water tank 111. The drainage mechanism 5 has a top plate 51 that cooperates with the water tank 111. A drainage hole 54 is penetrated on the top plate 51. A connecting plate 52 is fixedly installed at the lower end of the top plate 51. A float 53 is fixedly installed at the lower end of the connecting plate 52. Under normal conditions, the float 53 will fall above the channel 112 due to gravity, blocking the channel 112. Under normal conditions, the top plate 51 is located at the upper end of the water tank 111 and is flush with the end of the bottom plate 11.

[0046] Therefore, when there are water droplets generated by moisture or accumulated water that accidentally enters the protective shell, the water at this time will fall onto the bottom plate 11 due to gravity, and flow along the curved surface of the bottom plate 11 to the top plate 51. At this time, the water enters the water tank 111 through the drain hole 54. When the water stored in the water tank 111 reaches a certain capacity, the float 53 will drive the connecting plate 52 and the top plate 51 to move upward. At this time, the channel 112 is not blocked by the float 53, so that the water in the water tank 111 flows outward along the channel 112, thereby automatically discharging the water in the protective shell to the outside, preventing water and moisture from corroding and damaging the motor, so as not to damage the insulation, bearings and other key components of the motor.

[0047] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
