Photovoltaic power station rainproof combiner box

Abstract

The invention discloses a photovoltaic power station rainproof combiner box, which comprises a box body, the box body is in the shape of a cuboid, and the upper and lower ends of the box body are both openings, and the openings of the upper end surface and the lower end surface of the box body are respectively provided with upper seals with the same structure. The four corners of the box body are provided with connectors, which are connected with the upper and lower seal plates on the upper and lower sides of the box body through the connectors. One end of the connector extends out of the first boss, and the first boss The end face of the connecting piece is flush with one side of the box body, and the other end of the connector is provided with a box installation hole. Out of the sealing plate slot, the box body slot and the sealing plate slot are connected and fixed by fasteners and connectors; there is also a drain hole on the connector at the upper end of the box, and one end of the drain hole is located on the surface of the sealing plate slot. The other end is located on the side close to the installation hole of the box body, no welding is required, the structure is simple, and the processing difficulty is reduced.

Description

technical field [0001] The invention relates to a rainproof combiner box, in particular to a rainproof combiner box for a photovoltaic power station. Background technique [0002] The existing photovoltaic power station rainproof combiner box generally adopts welding technology. Welding needs to provide a larger place, and different welding methods need to be used for different sheet metal materials, not only the welding is complicated, but also requires high welding precision, which increases the difficulty of welding. After welding, it is necessary to polish the solder joints, which adds more processing steps, high cost, low work efficiency, and if there are problems such as missing welding and weak welding, it will not only affect the quality of the product and reduce the service life, but also There are potential safety hazards, causing unnecessary losses; at the same time, the general cabinets are required to be sprayed with plastic, and the welded cabinets must be com...

Welding needs to provide a larger place, and different welding methods need to be used for different sheet metal materials, not only the welding is complicated, but also requires high welding precision, which increases the difficulty of welding

After welding, it is necessary to polish the solder joints, which adds more processing steps, high cost, low work efficiency, and if there are problems such as missing welding and weak welding, it will not only affect the quality of the product and reduce the service life, but also There are potential safety hazards, causing unnecessary losses; at the same time, the general cabinets are required to be sprayed with plastic, and the welded cabinets must be completely welded and then sprayed with plastic. If the cabinet is large, it is not convenient to spray plastic
