[0030] In the present invention, the window frame bracket 2 is rotatably connected to the bottom of the fixed frame 13, and the dustproof cotton 15 is clamped on the window frame bracket 2 through the movable fixing frame 5 and the protective shutter 4. The dustproof cotton 15 isolates the pollutants at the air inlet and outlet of the energy storage box. When it is necessary to clean the dustproof cotton 15, the locking mechanism 3 is pulled outward, and the two ends of the locking mechanism 3 are pulled out from the locking groove 8, and the window frame bracket 2 can be turned from top to bottom. The movable fixing frame 5 is opened to pull out the dustproof cotton 15 for cleaning. Dry dust can be shaken or patted. Wet dust can be rinsed with water and dried before use. When the window frame bracket 2 is opened, the pull rod 10 is pulled downward to remove the dust through the shielding net. The curtain mechanism 11 blocks the window position of the fixed frame 13, and the original dust-proof cotton 15 is removed during cleaning to effectively protect the air inlet and outlet to prevent rain, snow, dust, etc. from entering the interior. The cleaned dust-proof cotton 15 is reset to its original position, and the edge of the dust-proof cotton 15 is stretched and tightened through the movable fixing frame 5 to avoid interception loopholes. At the same time, the shielding net curtain mechanism 11 is reset, and the window frame bracket 2 is flipped up from bottom to top to complete the cleaning operation of the dust-proof cotton 15. Each piece of dust-proof cotton 15 is allowed to be cleaned twice at most. Each time it is cleaned, the dust-proof efficiency will be reduced by 15%. It cannot be cleaned and used again after cleaning twice, and new dust-proof cotton needs to be replaced.

[0031] As a further solution in the present invention, the protective louver 4 includes laterally distributed fixed ribs and louver plates arranged on the outer side of the fixed ribs, and the inner side of the fixed ribs is a planar structure; in the present invention, the setting of the fixed ribs provides effective support for the outer side of the dust-proof cotton 15, and at the same time, enhances the mechanical strength of the louver plates, thereby improving the protective effect on the air inlet and outlet of the energy storage box.

[0032] As a further solution in the present invention, the movable fixing frame 5 includes an axis rod 51 rotatably connected to the window frame bracket 2, and a plurality of pressure rods 52 transversely installed on the axis rod 51, and the pressure rods 52 correspond to the fixed ribs, and a rectangular square tube 53 is installed between the outer ends of the pressure rods 52, and a positioning component compatible with the positioning groove 18 is arranged inside the rectangular square tube 53.

[0033] As a further solution in the present invention, the positioning component includes a slot 56 arranged in the middle of the rectangular square tube 53, and a rectangular rod 57 inserted at both ends of the rectangular square tube 53, and an elastic plate 58 with an arc structure is installed between the two rectangular rods 57. In the present invention, when the two movable fixing frames 5 are closed, the two elastic plates 58 are flipped outward and conflict with each other, and the rectangular rod 57 is pushed into the positioning slot 18 to complete the effective fixation of the movable fixing frame 5 to avoid the loosening of the dust-proof cotton 15. When the movable fixing frame 5 needs to be opened, the elastic plate 58 is pushed into the slot 56 to flip it inward, and the rectangular rod 57 is pulled inward to retract and disengage from the positioning slot 18, so that the movable fixing frame 5 can be opened, and the operation is simple and convenient.

[0034] As a further solution in the present invention, a rectangular storage groove 54 is provided on the inner side of the pressure rod 52, and an arc-shaped elastic support rod 55 is installed inside the storage groove 54. In the present invention, a plurality of elastic support rods 55 facing the shaft rod 51 are provided in the pressure rod 52. One end of the elastic support rod 55 extends outward when no force is applied. When the dust-proof cotton 15 is inserted into the window frame bracket 2 and the movable fixing frame 5 is closed, the outer end of the elastic support rod 55 contacts the edge of the dust-proof cotton 15. As the movable fixing frame 5 is pressed downward, the elastic support rod 55 supports the edge of the dust-proof cotton 15 outward and pulls it outward, and then cooperates with the inner side surface of the fixed rib rod to support and pull the two sides of the dust-proof cotton 15 at multiple points, thereby effectively avoiding the vibration of the dust-proof cotton 15 when subjected to wind force, and eliminating the problem of reduced protection capability caused by gaps at the edge of the dust-proof cotton 15.

[0035] As a further solution in the present invention, the shielding net curtain mechanism 11 includes a storage cylinder 111, and two winding springs 112 installed inside the storage cylinder 111, a winding drum 113 is fixedly installed between the two winding springs 112, and a shielding net curtain 114 is installed between the winding drum 113 and the pull rod 10, a cross bar 16 is installed at the bottom of the window frame bracket 2, and a locking buckle 17 that is engaged with the pull rod 10 is provided in the middle of the cross bar 16. In the present invention, when the window frame bracket When the window is flipped open, the locking buckle 17 moves to a vertical state, and the shielding net curtain 114 is pulled downward by the pull rod 10, and the shielding net curtain 114 is used to temporarily block the air inlet and outlet of the energy storage box, so as to prevent pollutants such as rain, snow, dust, etc. from entering the interior of the energy storage box from the air inlet and outlet during the cleaning process of the original dustproof cotton 15. At the same time, the locking buckle 17 is engaged with the locking buckle 17, and when the window frame bracket 2 is reset, the locking buckle 17 is separated from the pull rod 10 and quickly reset and stored under the action of the winding spring 112.

[0036] As a further solution in the present invention, a cleaning strip 115 is fixedly installed on the inner side of the slag discharge trough 9, and cleaning bristles 116 with an arc-shaped structure are provided on the side of the cleaning strip 115. In the present invention, when the shielding mesh curtain 114 is pulled downward, it slides along the arc-shaped surface of the cleaning bristles 116. When the shielding mesh curtain 114 is pulled back under the elastic force of the winding spring 112, the cleaning bristles 116 with the arc-shaped structure pass through the mesh holes of the shielding mesh curtain 114 in turn, brush off the impurities in the shielding mesh curtain 114, and push them into the slag discharge trough 9, so as to effectively clean the shielding mesh curtain 114.

[0037] As a further solution in the present invention, a soft magnetic strip is provided at the edge of the shielding net curtain 114, and magnetic steel strips 7 are provided on both side edges of the fixed frame 13 and are magnetically fixed to the magnetic strips.

The elastic member 6 includes a movable bolt 61 slidably connected to the fastening rod 12, and a tension spring 62 is installed between one end of the movable bolt 61 and the fastening rod 12, and an extrusion block 63 cooperating with the rectangular square tube 53 is provided at the other end of the movable bolt 61. In the present invention, when the window frame bracket 2 is flipped and reset, the elastic member 6 contacts the outer sides of the two rectangular square tubes 53 from bottom to top in turn, so that the tension spring 62 is in a tension state, and then the closed gap of the two movable fixing frames 5 is locked by the extrusion block 63, thereby forming pressure in the middle position of the dust-proof cotton 15, and further improving the stability of the dust-proof cotton 15 during the filtering process.

[0039] As a further solution in the present invention, the locking mechanism 3 includes two locking blocks 31 located at the outer ends, elastic pull rods 32 are installed at the ends of the two locking blocks 31, a transition rod 33 is rotatably installed between the ends of the two elastic pull rods 32, and a handle rod 34 is hinged between the two transition rods 33. In the present invention, the locking block 31 is embedded in the locking groove 8 under the elastic force of the elastic pull rod 32. When the handle rod 34 is pulled outward, the two elastic pull rods 32 are driven to move synchronously toward the middle, and then the two locking blocks 31 are pulled closer to the middle, completing the separation operation of the locking block 31 and the locking groove 8. The operation is simple and convenient.

[0040] When in use, if it is necessary to clean the dust-proof cotton 15, pull the locking mechanism 3 outwards, and the two ends of the locking mechanism 3 are pulled out from the locking grooves 8, and the window frame bracket 2 can be flipped from top to bottom, and the movable fixing frame 5 can be opened to pull out the dust-proof cotton 15 for cleaning, and the dry dust can be shaken or patted. The wet dust can be rinsed with water and dried before use. When the window frame bracket 2 is opened, pull the pull rod 10 downwards to cover the window position of the fixed frame 13 through the shielding net curtain mechanism 11. The original dust-proof cotton 15 is removed during cleaning. The air outlet is effectively protected to prevent rain, snow, dust, etc. from entering the interior. The cleaned dust-proof cotton 15 is reset to its original position, and the edge of the dust-proof cotton 15 is stretched and tightened by the movable fixing frame 5 to avoid interception loopholes. At the same time, the shielding net curtain mechanism 11 is reset, and the window frame bracket 2 is flipped up and fixed from bottom to top to complete the cleaning operation of the dust-proof cotton 15. Each piece of dust-proof cotton 15 is allowed to be cleaned twice at most. Each time it is cleaned, the dust-proof efficiency will be reduced by 15%. It cannot be cleaned and used again after cleaning twice, and new dust-proof cotton needs to be replaced.
