[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1 、 Figure 2 and Figure 5 , the utility model provides an embodiment: an integrated box-type substation, including a substation body 1, which is an integrated box-type substation for power conversion and distribution. It is an existing structure and can be implemented by technicians in this field. Since it is an existing technology, it will not be described in detail in this case. The bottom end of the right side of the substation body 1 is fixedly connected to an installation box 2 for installing a cleaning component. A blocking plate 3 is inserted on the right side of the installation box 2 for shielding and protecting internal equipment. A ventilation slot 4 is provided on the inner wall of the right side of the substation body 1. The ventilation slot 4 has multiple groups of holes near the left side of the substation body 1. The left side of the installation box 2 is connected to the ventilation slot 4. The crossflow fan blades 52 are connected so as to transport air to the ventilation slots 4, and dissipate heat to the equipment inside the substation body 1 through multiple groups of holes, thereby improving the heat dissipation effect. A cleaning component is provided on the inner wall of the installation box 2, and the cleaning component includes a drive motor 51 for driving the crossflow fan blades 52 to rotate. The outer wall of the drive motor 51 is fixedly connected to the inner wall of the installation box 2, and the rear side of the output shaft of the drive motor 51 is fixedly connected to the crossflow fan blades 52. By rotating, cold air can be sucked into the ventilation slots 4 to dissipate heat to the equipment inside the substation body 1. The outer wall of the rear side of the crossflow fan blades 52 is rotatably connected to the inner wall of the installation box 2, thereby improving the stability of the crossflow fan blades 52 during rotation.

[0034] Reference Figure 4 - Figure 6, a reducer 53 is provided on the rear side of the crossflow fan blade 52 for reducing the speed transmitted by the crossflow fan blade 52. It is an existing structure and can be implemented by technicians in this field. Since it is an existing technology, it will not be described in detail in this case. The front output shaft of the reducer 53 is fixedly connected to the rear side of the crossflow fan blade 52, and the rear output shaft of the reducer 53 is fixedly connected to an incomplete gear 54, which transmits the reduced speed to the rear output shaft of the reducer 53, thereby driving the incomplete gear 54 to rotate slowly. The outer wall of the reducer 53 is fixedly connected to the inner wall of the installation box 2, and a rack 55 is meshed with the right side of the incomplete gear 54. The rack 55 is driven downward by the teeth on the incomplete gear 54. When the teeth disengage from the rack 55, the rack 55 can be quickly reset under the action of the return spring 58 through the part without teeth of the incomplete gear 54. The outer wall of the rack 55 slides on the inner wall of the installation box 2, which improves the stability of the rack 55 when it moves up and down. The bottom end of the rack 55 is elastically connected to the installation box 2 by the return spring 58.

[0035] Reference Figure 4 and Figure 5 The top of the return spring 58 is fixedly connected to the bottom end of the rack 55, and the bottom end of the return spring 58 is fixedly connected to the inner wall of the installation box 2. The elastic force of the return spring 58 can drive the rack 55 to reset quickly, and at the same time, the rack 55 can move up and down. The front end of the rack 55 is fixedly connected to a cleaning rod 56. There are multiple groups of cleaning rods 56, which are evenly distributed on the rack 55. The interval between each group of cleaning rods 56 is set according to the distance that the incomplete gear 54 drives the rack 55 to move downward to ensure that the dust and impurities on the filter 57 are completely cleaned. The inner wall of the installation box 2 near the left side of the cleaning rod 56 is fixedly connected with a filter 57 for filtering dust and impurities in the air to prevent them from entering the substation body 1. The left side of the cleaning rod 56 slides on the right side of the filter 57. The bottom end of the installation box 2 near the right side of the filter 57 is provided with a dust outlet groove 6, which is set as a conical groove for removing the cleaned dust and impurities.

[0036] Reference Figure 3 and Figure 5If locking sill 752 snap on the positioning plate 74 away from that locking mouth 741 of coupling bar 73, then lock core 71 is in the state of being directly used for the fixing of bracket 71.

[0037] Working principle: When the substation body 1 needs to be cooled, the drive motor 51 is started, and the output shaft of the drive motor 51 drives the crossflow blades 52 to rotate. The crossflow blades 52 rotate to draw the outside air into the ventilation slots 4, so that the flowing air is transported to the inside of the substation body 1 through the holes on the ventilation slots 4, thereby improving the heat dissipation effect. At the same time, the rotation of the crossflow blades 52 reduces the speed of the speed reducer 53, thereby driving the incomplete gear 54 to rotate slowly. When the incomplete gear 54 rotates, The incomplete teeth on its surface engage with the rack 55, driving the rack 55 to move downward, and at the same time squeezing the return spring 58, thereby driving multiple groups of cleaning rods 56 to clean the dust adsorbed on the outer wall of the filter 57. When the toothed part of the incomplete gear 54 is no longer engaged with the rack 55, the elastic force of the return spring 58 drives the rack 55 to move upward, so that the rack 55 is reset to prepare for the next engagement with the incomplete gear 54. The cleaned dust and impurities fall into the dust outlet chute 6 and are discharged from the installation box 2.

[0038] When it is necessary to disassemble the blocking plate 3, the limiting rod 71 is pulled to slide into the inner wall of the installation box 2. At the same time, the limiting rod 71 drives the blocking plate 72 to slide on the inner wall of the installation box 2 and squeezes the compression spring 73 to release the limiting rod 71 from the limitation of the blocking plate 3. At this time, the blocking plate 3 is pulled out from the inner wall of the installation box 2, and the disassembly of the blocking plate 3 is completed. At this time, the dust outlet 6, multiple sets of cleaning rods 56 and the filter screen 57 can be maintained.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
