Description
Technical Field
[0001] This utility model relates to the field of dust prevention technology for underground electromechanical equipment in coal mines, specifically a dust prevention structure for underground electromechanical equipment in coal mines. Background Technology
[0002] Coal mine underground electromechanical equipment is a general term for various mechanical equipment and electrical devices used in the coal mine production process to provide power, control, transportation, ventilation and other functions. Due to long-term use in coal mines, a large amount of dust can easily accumulate on the motor equipment, affecting the heat dissipation of the motor. Therefore, it is necessary to protect the motor to ensure effective heat dissipation and extend its service life.
[0003] In order to prevent a large amount of dust from adhering to the surface of the motor, existing electromechanical equipment usually uses a dustproof box to protect the motor. However, in actual use, the motor is in a dusty environment. Although the dustproof box is equipped with a filter screen, which can effectively prevent dust, long-term use can easily cause the filter screen to become clogged, affecting the heat dissipation effect. It requires staff to clean it regularly. However, the dust in the mine is large, and cleaning can not be sustained for long before it needs to be cleaned again, which is quite troublesome and reduces its practicality. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide a dustproof structure for underground electromechanical equipment in coal mines, solving the problem that when motor equipment is used in underground coal mines, the filter screen on the dustproof box is covered with a large amount of dust, causing the filter holes to become clogged, preventing effective heat dissipation, requiring frequent cleaning, and thus increasing the labor intensity of workers, which is quite troublesome.

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.
[0035] like Figures 1 to 7As shown in the figure, this utility model provides a dustproof structure for underground electromechanical equipment in coal mines, including a dustproof box 1. A base 11 is fixedly connected to the bottom wall of the dustproof box 1, and a motor 12 is fixedly connected to the upper surface of the base 11. An air inlet 13 and an air outlet 14 are respectively opened on both sides of the dustproof box 1. The use of the air inlet 13 and the air outlet 14 can ensure air circulation and heat dissipation in the dustproof box 1. A cooling fan 15 is provided at the air outlet 14. A fixed frame 16 is fixedly connected to both sides of the dustproof box 1. A moving groove 17 is opened on the lower surface of the fixed frame 16. A baffle 18 is slidably connected in the moving groove 17. A limit frame 19 is fixedly connected to one side of the fixed frame 16. A retaining block 51 is fixedly connected to one side of the limit frame 19. An electric motor is fixedly connected to the lower surface of the retaining block 51. Telescopic rod 52, with a stabilizing block 53 fixedly connected to the movable end of the electric telescopic rod 52. The stabilizing block 53 is fixedly connected to the baffle plate 18. When the two electric telescopic rods 52 retract, they lift up with their respective baffle plates 18 to block the air inlet 13 and the air outlet. Cleaning brushes 20 are fixedly connected to the inner walls on both sides of the limiting frame 19. A dust filter plate 21 is movably connected between the two cleaning brushes 20. A connecting plate 22 is fixedly connected to the upper surface of the dust filter plate 21. The connecting plate 22 is slidably connected to the dust box 1. Connecting blocks 23 are fixedly connected to both sides of the connecting plate 22. An electric telescopic column 24 is fixedly connected to the lower surface of the connecting block 23. A fixing block 25 is fixedly connected to the end of the electric telescopic column 24 away from the connecting block 23. The fixing block 25 is connected to the dust box. 1. Fixed connection: A protective canopy 26 is provided above the dustproof box 1. With the assistance of an electric telescopic column 24, the electric telescopic column 24 moves the connecting plate 22 upwards, causing the connecting plate 22 to slide between two cleaning brushes 20, thus quickly cleaning the dust on the dustproof filter plate 21. Buffer columns 31 are fixedly connected to the four corners of the lower end face of the protective canopy 26. Fixed columns 32 are slidably connected to the outer wall of the buffer columns 31. The fixed columns 32 are fixedly connected to the dustproof box 1. A buffer groove 33 is opened inside the fixed column 32, and a buffer spring 34 is fixedly connected inside the buffer groove 33. The buffer spring 34 is fixedly connected to the buffer column 31. By sliding the four buffer columns 31 within their respective buffer grooves 33, the buffer springs can effectively clean the dust on their respective buffers. Spring 34 is compressed, and in conjunction with the rebound of buffer spring 34, it cushions the impact on the anti-smashing canopy 26, thereby protecting the dustproof box 1. Two symmetrical guide grooves 41 are provided on the side of the connecting plate 22 that contacts the dustproof box 1. Guide blocks 42 are slidably connected within the guide grooves 41 and are fixedly connected to the connecting plate 22. The use of the four guide grooves 41 and four guide blocks 42 guides the corresponding connecting plates 22, ensuring sufficient stability of the connecting plates 22 carrying the dustproof filter plate 21 during lifting and lowering. Two symmetrical positioning frames 61 are fixedly connected to the outer wall of the cooling fan 15 and are fixedly connected to the dustproof box 1. The use of the positioning frames 61 fixes the cooling fan 15, ensuring its stable operation.Support feet 71 are fixedly connected to the four corners of the lower end face of the dustproof box 1. Positioning holes 72 are provided on the support feet 71. The use of the four support feet 71 provides stable support for the dustproof box 1, and the positioning holes 72 fix the position of the dustproof box 1 to prevent random displacement. A door 81 is hinged to one side of the dustproof box 1, and a handle 82 is fixedly connected to the door 81. The door 81 and handle 82 facilitate the opening and closing of the dustproof box 1, making it convenient for subsequent maintenance and inspection of the motor 12 inside the dustproof box 1.
[0036] The working principle and usage process of this utility model are as follows: First, when the motor 12 is running, the use of the air inlet 13 and air outlet 14 ensures airflow within the dustproof box 1, effectively dissipating heat. Combined with the use of two dust filter plates 21, external dust is blocked, preventing it from entering the dustproof box 1 and adhering to the motor 12. After the dust filter plates 21 have been in use for a period of time, the two electric telescopic rods 52 retract simultaneously, causing the two baffle plates 18 to slide within the fixed frame 16, blocking the air inlet 13 and air outlet. Then, the four electric telescopic columns 24 extend, moving their corresponding connecting plates 22 upwards, allowing the connecting plates 22 to slide the dust filter plates 21 between the two cleaning brushes 20. The cleaning brushes 20 then clean the dust filter plates 21. After cleaning, the electric telescopic columns 24 retract, the dust filter plates 21 return to their original position, the electric telescopic rods 52 extend, and the baffle plates 18 move downwards, ensuring ventilation of the dustproof box 1. This completes the usage process of the entire dustproof structure.
