[0035] The following is combined with Figure 1-7 This application is described in further detail.

[0036] Example 1

[0037] This embodiment discloses an outdoor box-type substation. Figure 1 and Figure 2 An outdoor box-type substation includes a box body 1 and a box door 2. A receiving groove 11 is provided on the side of the box body 1. The box door 2 is rotatably connected to the box body 1 and is located in the receiving groove 11.

[0038] Reference Figure 2 and Figure 3 The end surface of the door 2 facing the bottom wall of the accommodating groove 11 is provided with a mounting groove 21, and the bottom wall of the mounting groove 21 is provided with a vent 22. The bottom wall of the mounting groove 21 is fixedly connected with a mounting frame 3, and the mounting frame 3 surrounds the outside of the vent 22.

[0039] Reference Figure 2 and Figure 3 A plurality of mounting plates 23 are fixedly connected between the inner walls of the mounting frame 3 on both sides. The plurality of mounting plates 23 are arranged in an array along the vertical direction. The height of the mounting plates 23 gradually decreases as they move away from the bottom wall of the receiving groove 11.

[0040] Reference Figure 2 and Figure 3 The highest point of the mounting plate 23 is fixedly connected with a blocking bar 231. One end of the blocking bar 231 is fixedly connected to the horizontal inner wall of the mounting frame 3, and the other end of the blocking bar 231 is fixedly connected to the horizontal inner wall of the other side of the mounting frame 3.

[0041] Reference Figure 2 and Figure 3 The end surface of the mounting frame 3 facing away from the bottom wall of the mounting groove 21 is provided with a filter screen 4. The filter screen 4 includes a mesh portion 41 that can block the opening of the mounting frame 3. The end surface of the mounting frame 3 facing the mesh portion 41 is fixedly connected to a child hook-and-loop fastener 31. The end surface of the mesh portion 41 facing the mounting frame 3 is fixedly connected to a female hook-and-loop fastener 42. The female hook-and-loop fastener 42 can be bonded to the child hook-and-loop fastener 31.

[0042] The implementation principle of Example 1 is: when the filter screen 4 needs to be replaced, the mother Velcro 42 of the filter screen 4 is separated from the child Velcro 31 on the installation frame 3, that is, the filter screen 4 is separated from the installation frame 3, and then the new filter screen 4 is connected to the installation frame 3, so that the mother Velcro 42 of the new filter screen 4 is bonded and matched with the child Velcro 31 on the installation frame 3.

[0043] Example 2

[0044] Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that the filter screen 4 further includes an elastic portion 43. Two elastic portions 43 are provided, the upper end surface of the mesh portion 41 is fixedly connected to one elastic portion 43, and the lower end surface of the mesh portion 41 is fixedly connected to the other elastic portion 43.

[0045] Reference Figure 4 and Figure 5 The end of the elastic portion 43 away from the mesh portion 41 is fixedly connected to the hook portion 44. The upper and lower end surfaces of the mounting frame 3 are fixedly connected to the mounting bar 32. The end surface of the mounting bar 32 facing the bottom wall of the accommodating groove 11 is provided with a slot 321. The slot 321 can accommodate the hook portion 44.

[0046] The implementation principle of Example 2 is: driving the hook portion 44 to move toward the mounting bar 32, so that the elastic portion 43 is stretched, so that the hook portion 44 can be snapped into the slot 321, and the force generated by the resetting of the elastic portion 43 is applied to the grid portion 41, so that the elastic portion 43 fits more tightly with the mounting frame 3.

[0047] Example 3

[0048] Reference Figure 6 and Figure 7 This embodiment differs from Embodiment 2 in that a cleaning structure 5 is provided on the mounting frame 3, capable of cleaning the filter 4. The cleaning structure 5 includes an operating bar 51, a movable rod 52, and bristles 53. Two operating bars 51 are provided, arranged horizontally. The filter 4 is positioned between the two operating bars 51. A chute 511 is defined on the adjacent end surfaces of the two operating bars 51, extending vertically upward through the operating bars 51.

[0049] Reference Figure 6 and Figure 7 One end of the movable rod 52 is inserted into a chute 511, and the other end of the movable rod 52 is inserted into another chute 511. The bristles 53 are fixedly connected to the end surface of the movable rod 52 facing the filter screen 4.

[0050] Reference Figure 6 and Figure 7The operating bar 51 is provided with a limit assembly 54, which is used to limit the movement of the movable rod 52. A threaded hole 512 is defined on the end surface of the operating bar 51, facing away from the mounting frame 3. The limit assembly 54 includes a screw 541, which is threadably coupled to the threaded hole 512. When the screw 541 is inserted into the chute 511, it is positioned in the upward movement path of the movable rod 52.

[0051] The implementation principle of Example 3 is as follows: when the filter 4 needs to be cleaned, the movable rod 52 is driven up and down to make the bristles 53 clean the filter 4. When the cleaning structure 5 needs to be replaced, the screw rod 541 is driven to rotate, so that the movable rod 52 moves upward to disengage the chute 511, and the cleaning structure 5 is replaced again.
