Description

Technical Field

[0001] This utility model belongs to the field of inverter grid-connected cabinet manufacturing technology, specifically relating to a tray for inverter grid-connected cabinets. Background Technology

[0002] Inverter grid-connected cabinets typically have multiple trays (support plates) installed in an up-down structure. The trays (support plates) can vertically divide the cavity of the inverter grid-connected cabinet to improve the space utilization of the cavity. The trays (support plates) are used to house grid-connected inverters, batteries, switches, etc. Our company currently produces pallets, such as Figures 1-3 The pallet body 1' comprises a base plate 11', a left side plate 12', a right side plate 13', a front side plate 14', and a rear side plate 15'. A left side plate is located on the left side of the upper surface of the base plate, a right side plate is located on the right side of the upper surface of the base plate, a front side plate is located on the front side of the upper surface of the base plate, and a rear side plate is located on the rear side of the upper surface of the base plate. The front side plate is formed by bending upwards from the front extension plate of the base plate and is in the shape of a "7". The rear side plate is formed by bending upwards from the rear extension plate of the base plate. The left side plate is formed by bending upwards from the left extension plate of the base plate, and the right side plate is formed by bending upwards from the right extension plate of the base plate. The "7"-shaped front side plate is located between the left and right side plates. "7"-shaped weld seams 16' are formed between the left and right side plates and their corresponding sides of the front side plate. The front and left side plates are fixed by fully welding the corresponding "7"-shaped weld seams between them. The front and right side panels are fixedly connected by fully welding the corresponding "7"-shaped weld seams between them. The horizontal plate of the "7"-shaped front side panel has multiple first mounting holes 17' that penetrate the upper and lower ends of the horizontal plate. The left side panel has multiple second mounting holes that penetrate the inner and outer sides of the left side panel, and a rivet nut is installed in each of the second mounting holes. The right side panel has multiple third mounting holes that penetrate the inner and outer sides of the right side panel, and a rivet nut is installed in each of the third mounting holes. The rear side panel is located between the left and right side panels. The left and right side panels each form a "1"-shaped weld seam with the corresponding side of the front side panel. The front and left side panels are fixedly connected by fully welding the corresponding "1"-shaped weld seams 18' between them. The front and right side panels are also fixedly connected by fully welding the corresponding "1"-shaped weld seams between them. Its shortcomings are: the existing pallets have “I” shaped welds between the front and left side panels and between the side and right side panels. After the “I” shaped welds are welded, their weld strength is relatively poor, which affects the service life of the pallets. Utility Model Content

[0003] Design objective: To avoid the shortcomings of the prior art, a tray for inverter grid-connected cabinets with better welding strength between the rear side panel and the left and right side panels is designed.

The rear and left panels are fixedly connected by fully welding the corresponding L-shaped weld seams between them. The rear and right panels are also fixedly connected by fully welding the corresponding L-shaped weld seams between them. The L-shaped weld seams extend the weld length, and the L-shaped welding structure allows the rear and right panels (rear and left panels) to be welded together in both the vertical and horizontal directions, greatly improving the weld strength between them and thus increasing the service life of the tray used in inverter grid-connected cabinets.

[0006] 2. The design of having a row of strip-shaped through holes on the upper surface of the base plate, with the strip-shaped through holes penetrating both the upper and lower ends of the base plate, and a row of rectangular through holes on the upper surface of the base plate, is the second technical feature of this utility model. The purpose of this design is that the strip-shaped and rectangular through holes on the upper surface of the base plate provide heat dissipation and weight reduction; furthermore, the width of the strip-shaped through holes matches the diameter of the M5 screws, allowing the strip-shaped through holes to be used for fixing equipment (grid inverters, batteries, switches) when needed. A screw is used to secure the device after the threaded holes on the equipment align with the corresponding strip-shaped through holes.

[0007] 3. The design of having at least one through hole on the upper surface of the base plate, with a rivet nut installed inside the through hole, is the third technical feature of this utility model. The purpose of this design is that the upper surface of the base plate has at least one through hole with a rivet nut installed inside the through hole; the rivet nut on the base plate is for subsequent expansion use.
