[0001] The present application relates to the technical field of power supply casings, and in particular to a frame-type casing for a dust collector power supply. Background Art

[0002] The electrostatic precipitator needs a high-frequency and high-voltage power supply to provide a high-voltage electrostatic field to work. The high-frequency and high-voltage power supply is generally placed next to the precipitator. The precipitator is outdoors, so the high-frequency and high-voltage power supply is also placed outdoors. This requires the housing of the high-frequency and high-voltage power supply to be able to protect the power supply under harsh outdoor conditions. For example, the patent application number is CN 212812282 U, and the patent name is a utility model patent for a frame-type new housing for a power supply. Its features include a cubic frame, and the left and right sides and the rear side of the frame are respectively provided with detachable side panels, and the front side of the frame is provided with a detachable front door, and the front door includes two door panels of the same size, and the front door is provided with a circular through hole with the joint of the two door panels as the center line, and the upper end of the frame is provided with a detachable top cover, and the top cover is provided with a plurality of through holes, and the through holes are provided with through hole covers, and the top cover is a whole plate tilted downward from front to back.

[0003] Although this solution solves the waterproof problem of the power supply, the gap between the top cover and the frame mating surface is large and the air tightness is poor, which prevents the external air from flowing through the power transformer better and reduces the heat dissipation effect. Utility Model Content

[0004] The purpose of the present application is to overcome the problem in the prior art that the gap between the top cover and the frame mating surface is large, the air tightness is poor and this affects the heat dissipation of the internal power transformer, and to provide a frame-type housing for a dust collector power supply.

[0005] Specifically, the frame-type casing for a dust collector power supply comprises: a frame, the frame is arranged in a cubic structure, both sides of the frame are provided with removable side doors, the rear side of the frame is provided with a removable rear door, and the front side of the frame is provided with a removable front door; a top cover, the top cover comprises a plate body, a top cover square tube and a surrounding plate, the bottom surface of the plate body is fixed with top cover square tubes connected end to end around, the outer sides of the top cover square tubes are fixed with surrounding plates connected end to end, the top cover is closed on the frame and the surrounding plates are wrapped around the outside of the top of the frame.

[0006] In some possible implementations, the frame includes a side door frame, an upper connecting block and a base connecting block, wherein the side door frame includes an upper arm, a lower arm and two columns, and the upper arm, the lower arm and the columns form a rectangular frame structure. The number of the side door frames is two, and the upper ends of the two side door frames are fixedly connected by the upper connecting block, and the lower ends of the two side door frames are fixedly connected by the base mounting block. There is no need to additionally set a lower cross block at the lower end of the side door frame, and the side door is used to merge the lower cross block, so that there is no need to additionally remove the lower cross block when inspecting the fan, thereby facilitating the inspection of the fan.

[0007] In some possible implementations, the number of the upper connecting blocks is two, and the upper connecting block and the upper arm of the side door frame form a rectangular frame structure, and the upper connecting block and the side door frame are fixed by snap-fitting, and the snap-fitting corresponding bolt fixing makes it more convenient to assemble the upper connecting block and the side door frame.

[0008] In some possible implementations, the upper connecting block and the upper arms of the side door frame are both stainless steel square tubes, and the upper arms of the connecting block and the side door frame are both fitted with the top cover square tube. The stainless steel square tube not only has the advantages of high strength, good plasticity, heat resistance, and oxidation resistance, but also has the characteristic of high flatness, which makes the upper arms of the connecting block and the side door frame fit more closely with the top cover square tube, further increasing the air tightness of the mating surface between the top cover and the frame.

[0009] In some possible implementations, the number of the base mounting blocks is two, and both ends of the base mounting blocks are respectively fixedly connected to the lower ends of the columns of the two side door frames.

[0010] In some possible implementations, the front door includes two door panels, and a circular through hole with a seam between the two door panels as the center line is provided on the front door. The front door is composed of two door panels, which facilitates the installation of a high-pressure porcelain bottle.

[0011] In some possible implementations, the inner walls of the side doors, rear door, front door and top cover are fixed with reinforcing ribs. By providing the reinforcing ribs, the thickness of the plate can be reduced while ensuring the structural strength of the side doors, rear door, front door and top cover, thereby reducing the cost of the side doors, rear door, front door and top cover.

[0012] In some possible implementations, the top cover is arranged at an angle, and the inclined arrangement of the top cover can prevent the accumulation of rainwater on the top cover and reduce the erosion of the top cover by rainwater.

[0013] In some possible implementations, the plate body is provided with a plurality of through holes, and each of the through holes is provided with a through hole cover. The provision of the through holes facilitates hoisting of the assembled frame-type housing. After the hoisting is completed, the through holes are sealed with the through hole covers to prevent rainwater from entering the interior of the housing through the through holes.

[0014] In some possible implementations, at least one lifting ring is fixed on the plate body, and the provision of the lifting ring facilitates lifting of the assembled frame-type housing.

[0015] The present application has the following beneficial effects: the present application processes the frame in an outward-inward manner through the frame enclosure, so that the square tube of the top cover can maintain a good fit with the top surface of the frame, thereby ensuring waterproofness while increasing the air tightness between the top cover and the frame, making it difficult for external air to flow out from the connection between the top cover and the frame, so that the external air can better flow through the power transformer, ensuring the heat dissipation effect of the power transformer installed inside.

[0034] like Figure 3-Figure 5 As shown, it also includes a top cover 5, which includes a plate body 51, a top cover square tube 52 and a surrounding plate 53. The top cover square tube 52 connected end to end is fixed to the four sides of the bottom surface of the plate body 51, and the outer side of the top cover square tube 52 is fixed with a surrounding plate 53 connected end to end. The top cover 5 is covered on the frame 1 and the surrounding plate 53 is wrapped around the outside of the top of the frame 1. Among them, the surrounding plate 53 can be fixedly connected to the plate body 51, and the surrounding plate 53 can also be fixedly connected to the top cover square tube 52. Of course, the surrounding plate 53 can also be fixedly connected to both the plate body 51 and the top cover square tube 52. The fixed connection not only plays a role in rainproof, but also can limit the frame 1 and the top cover 5, so that the upper arm 111 of the connecting gear and the side door frame 11 are both fitted with the top cover square tube 52, so that the top cover square tube 52 can maintain a good fit with the top surface of the frame 1, thereby ensuring waterproofness while increasing the air tightness between the top cover 5 and the frame 1, making it difficult for external air to flow out from the connection between the top cover 5 and the frame 1, so that the external air can better flow through the power transformer, ensuring the heat dissipation effect of the power transformer installed inside, such as Figure 2 As shown, the plate body 51 is provided with a plurality of through holes 8 , and each of the through holes 8 is provided with a through hole cover 9 .

[0035] like Figure 6 and Figure 7 As shown, connecting plates 121 are fixed at both ends of the upper connecting step 12, and connecting seams 1131 adapted to the connecting plates 121 are reserved at the upper ends of the columns 113 of the side door frame 11.

[0039] like Figure 3-Figure 5 As shown, it also includes a top cover 5, which includes a plate body 51, a top cover square tube 52 and a surrounding plate 53. The top cover square tube 52 connected end to end is fixed to the four sides of the bottom surface of the plate body 51, and the outer side of the top cover square tube 52 is fixed with a surrounding plate 53 connected end to end. The top cover 5 is covered on the frame 1 and the surrounding plate 53 is wrapped around the outside of the top of the frame 1. Among them, the surrounding plate 53 can be fixedly connected to the plate body 51, and the surrounding plate 53 can also be fixedly connected to the top cover square tube 52. Of course, the surrounding plate 53 can also be fixedly connected to both the plate body 51 and the top cover square tube 52. The fixed connection not only plays a role in rainproof, but also can limit the frame 1 and the top cover 5, so that the upper arm 111 of the connecting gear and the side door frame 11 are both fitted with the top cover square tube 52, so that the top cover square tube 52 can maintain a good fit with the top surface of the frame 1, thereby ensuring waterproofness while increasing the air tightness between the top cover 5 and the frame 1, making it difficult for external air to flow out from the connection between the top cover 5 and the frame 1, so that the external air can better flow through the power transformer, ensuring the heat dissipation effect of the power transformer installed inside, such as Fig. 9 As shown, at least one lifting ring 10 is fixed on the plate body 51 .

[0040] like Figure 6 and Figure 7 As shown, connecting plates 121 are fixed at both ends of the upper connecting step 12, and connecting seams 1131 adapted to the connecting plates 121 are reserved at the upper ends of the columns 113 of the side door frame 11. During assembly, the connecting portion at the end of the upper connecting step 12 is inserted into the connecting seam 1131 to achieve a clamping fixation between the upper connecting step 12 and the columns 113 of the side door frame 11.

[0041] When in use, the power supply device is installed on the base, and then the frame 1 type housing in this embodiment is covered on the base to form a closed whole. The assembly sequence is: firstly, fasten the side door frame 11 and the base connecting block 13 to the power supply base with screws, then insert the connecting plate 121 of the upper connecting block 12 into the connecting seam 1131 of the side door frame 11, cover the top cover 5, and finally install the four side door 2 panels. After the power supply equipment is installed, it can be hoisted to the required position through the lifting ring 10 on the outer shell. The inclined setting of the top cover 5 can avoid the accumulation of rainwater on the top cover 5 and reduce the erosion of rainwater on the top cover 5. By setting the reinforcing ribs 7, the thickness of the plate can be reduced while ensuring the structural strength of the side door 2, the rear door 3, the front door 4 and the top cover 5, thereby reducing the cost of the side door 2, the rear door 3, the front door 4 and the top cover 5. Fixing the upper connecting block 12 and the side door frame 11 with corresponding bolts by means of snap-fits makes it more convenient to assemble the upper connecting block 12 and the side door frame 11. Secondly, there is no need to set an additional lower cross bar at the lower end of the side door frame 11. The side door 2 is used to merge the lower cross bar, so that there is no need to remove the lower cross bar when repairing the fan, thereby facilitating the repair of the fan that dissipates heat inside.
