[0031] The following section will explain the specific settings and functions of the replacement structure 7 and auxiliary structure 8.

[0032] Reference Figures 1-4 As shown, in this embodiment: the replacement structure 7 includes a mesh roll 77 located on one side of the mounting base 1. A mesh strip 76 is wound around the side wall of the mesh roll 77, and the mesh strip 76 is positioned above the air outlets 6 on several air inlet pipes 5. By setting up the replacement structure 7, the tedious process of disassembling and cleaning the traditional mesh cover is avoided, improving the efficiency of handling the blockage problem of the air outlets 6. Two mounting plates 78 are fixedly connected to the side wall of the mounting base 1. Bolts 79 are inserted into the internal threads of the mounting plates 78. The mesh roll 77 is located between the two bolts 79, and the mesh roll 77 is sleeved on the outside of the bolts 79. The bolts 79 pass through the mesh roll 77. By rotating the bolts 79, the mesh roll 77 can be removed and replaced with a new mesh roll 77, thus quickly completing the replacement of the mesh roll 77. A connecting plate 72 is fixedly connected to the other side of the mounting base 1, and a rolling rod 71 is rotatably connected inside the connecting plate 72. The setting of the rolling rod 71 facilitates subsequent replacement. A circular plate 74 is fixedly connected to the end of the winding rod 71, and a screw 73 is threaded into the inside of the circular plate 74. One side of the mesh tape 76 is wound around the winding rod 71, and rotating the winding rod 71 allows for the winding and unwinding of the replaced mesh tape 76. The surface of the connecting plate 72 has a circumferential array of several insertion holes 75, the size of which matches the size of the screw 73. After replacing the mesh tape 76, rotating the screw 73 and inserting it into the corresponding insertion hole 75 allows for the twisting and fixing of the winding rod 71.

[0033] Reference Figures 1-2 and Figure 5As shown, specifically, the auxiliary structure 8 includes a positioning plate 81 fixedly connected to the end of the air intake pipe 5 away from the slider 4. A limiting strip 82 is fixedly connected to the upper surface of the positioning plate 81. A rectangular plate 84 is slidably connected to the side wall of the limiting strip 82. An arc-shaped frame 85 is fixedly connected to the side wall of the rectangular plate 84, and the arc-shaped frame 85 is located above the mesh belt 76. By setting the auxiliary structure 8, it is ensured that the mesh belt 76 can accurately cover the air outlet 6, while maintaining the stability of the mesh belt 76 during replacement. A drive rod 83 is threadedly connected to the inside of the rectangular plate 84, and the drive rod 83 is rotatably connected to the inside of the positioning plate 81. Rotating the drive rod 83, the drive rod 83 is rotatably connected to the positioning plate 81 and threadedly connected to the rectangular plate 84. When the drive rod 83 rotates, it can drive the rectangular plate 84 to slide along the limiting strip 82.

[0034] Working principle: During the operation of coal mine electromechanical equipment, cold outside air enters through the air inlet pipe 5 and is blown out through the air outlet 6 to cool the equipment. Because the air outlet 6 is small, a replacement structure 7 is installed to prevent blockage. The mesh belt 76 wound on the mesh roll 77 is located above the air outlet 6, serving as a dust preventer. When the mesh belt 76 accumulates a lot of dust, affecting the airflow from the air outlet 6, one side of the mesh belt 76 is wound around the winding rod 71. Rotating the winding rod 71 allows for the winding and unwinding of the replaced mesh belt 76. The mesh belt 76 can be wound and unwinded by winding the winding rod 71. The operation involves pulling the screen to replace the mesh belt 76 located above the air outlet 6. After replacing the mesh belt 76, the screw 73 is inserted into the inner side of the corresponding insertion hole 75, which allows the roll rod 71 to be twisted and fixed. The mounting plate 78 is fixedly connected to the side wall of the mounting base 1, and the bolt 79 passes through the mesh roll 77. By rotating the bolt 79, the mesh roll 77 can be removed and replaced with a new mesh roll 77, thus quickly completing the replacement of the mesh roll 77. By setting the replacement structure 7, the tedious process of disassembling and cleaning the traditional mesh cover is avoided, and the efficiency of dealing with the blockage problem of the air outlet 6 is improved.

[0035] During the replacement of the mesh belt 76, the auxiliary structure 8 plays a role in assisting positioning and adjustment. The positioning plate 81 is fixed on the air inlet pipe 5, the limiting strip 82 is connected to the positioning plate 81, the rectangular plate 84 slides on the limiting strip 82, and the arc frame 85 is connected to the side wall of the rectangular plate 84 and located above the mesh belt 76. The drive rod 83 is rotated and is rotatably connected to the positioning plate 81 and threadedly connected to the rectangular plate 84. When the drive rod 83 rotates, it can drive the rectangular plate 84 to slide along the limiting strip 82, thereby adjusting the position of the arc frame 85, which facilitates the positioning and fixing of the mesh belt 76. By setting the auxiliary structure 8, it is ensured that the mesh belt 76 can accurately cover the air outlet 6, and the mesh belt 76 is kept stable during the replacement process.
