[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the specification drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Referring to Figures 1 - 3 , an embodiment provided by the present invention: a new type of lifting explosion-proof motor, including an explosion-proof motor body 10. The lower end surface of the explosion-proof motor body 10 is fixedly connected with a mounting plate 1. Four mounting holes 6 are opened on one end surface of the mounting plate 1. The mounting holes 6 facilitate the installation of the protective box 2 and the mounting plate 1 at the place where the explosion-proof motor body 10 needs to be installed. One end surface of the mounting plate 1 is fixedly connected with a protective box 2. The protective box 2 completely covers the explosion-proof motor body 10. An output end 8 is provided inside the explosion-proof motor body 10. The output end 8 penetrates through one end surface of the protective box 2 and extends to the outside of the protective box 2. A sealing ring 9 is provided on the outer wall of the output end 8. The sealing ring 9 can prevent dust from entering the protective box 2 through the output end 8. A plurality of first heat dissipation holes 14 are opened on one end surface of the protective box 2 away from the explosion-proof motor body 10. One end surface of the protective box 2 is rotatably connected with a box door 7 through a hinge. The inner wall of the protective box 2 is bolted with a first mounting frame 11. A filter plate 18 is provided inside the first mounting frame 11. The side end surface of the protective box 2 is rotatably connected with a knob 16. One end surface of the knob 16 is fixedly connected with a rotating shaft 17. The rotating shaft 17 penetrates through the bottom end surface of the side wall of the protective box 2 and is fixedly connected with a threaded rod 19. The outer wall of the threaded rod 19 is threadedly connected with a slide plate 20. The inner wall of the protective box 2 is fixedly connected with a guide rod 22. The guide rod 22 is slidably connected with the slide plate 20. One end surface of the slide plate 20 close to the filter plate 18 is fixedly connected with a brush 21. The brush 21 closely adheres to one end surface of the filter plate 18. A heat dissipation component is provided inside the protective box 2.

[0024] Specifically, the interior of the slide plate 20 is provided with threads adapted to the threaded rod 19. The filter plate 18 can intercept the dust passing through the second heat dissipation holes 15. The rotation of the knob 16 is transmitted to the threaded rod 19 through the rotating shaft 17, thereby driving the threaded rod 19 to rotate. Therefore, the slide plate 20 can move linearly, and the guide rod 22 can prevent the slide plate 20 from shifting during movement. Therefore, the slide plate 20 can drive the brush 21 to remove the dust on the filter plate 18, increasing the service life of the filter plate 18.

[0025] Referring to Figure 1 , Figure 2 and Figure 4 , the heat dissipation component includes a heat dissipation fan 23 and a heat sink 24. The inner wall of the protection box 2 is fixedly connected to a fixing plate 12. A number of second heat dissipation holes 15 are opened inside the fixing plate 12. One end surface of the fixing plate 12 is fixedly connected to a second mounting frame 13. The inner wall of the second mounting frame 13 is fixedly connected to the heat dissipation fan 23, and the inner wall of the second mounting frame 13 is fixedly connected to the heat sink 24. The heat sink 24 is arranged in front of the heat dissipation fan 23.

[0026] Specifically, on the one hand, the second heat dissipation holes 15 are beneficial to gas exchange, and on the other hand, they are for the stable operation of the heat dissipation fan 23. The heat sink 24 usually has a large surface area to increase the contact area with the surrounding air, thereby improving the heat dissipation efficiency. The two are used in combination to reduce the temperature of the explosion-proof motor body 10 when the explosion-proof motor body 10 is working, and prevent the explosion-proof motor body 10 from affecting its working efficiency due to excessive temperature.

[0027] Referring to Figure 1 , two first mounting ears 3 are fixedly connected to the upper part of one end surface of the protection box 2 close to the knob 16, and two second mounting ears 4 are fixedly connected to one end surface of the box door 7 close to the knob 16. The first mounting ears 3 and the second mounting ears 4 are fixedly connected by fasteners 5.

[0028] Specifically, the cooperation of the first mounting ears 3 and the second mounting ears 4 can prevent the box door 7 from being accidentally opened.

[0029] Working principle: Install the explosion-proof motor body 10 on the mounting plate 1, close the box door 7. When the explosion-proof motor body 10 is working, turn on the heat dissipation fan 23. The combination of the heat dissipation fan 23 and the heat sink 24 can work effectively together to improve the heat dissipation effect and reduce the temperature of the explosion-proof motor body 10 during operation; when the explosion-proof motor body 10 stops working, rotate the knob 16 to indirectly rotate the threaded rod 19, so that the slide plate 20 drives the brush 21 to clean the filter plate 18.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
