Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

In the present embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right side", "left end", "above", "back", "middle", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description of the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the present embodiment, if the connection or fixing manner between the components is not specifically described, the connection or fixing manner may be a bolt fixing manner, a pin connecting manner, or the like, which is commonly used in the prior art, and therefore, details thereof are not described in the present embodiment.

Examples

A solar cell with a deep circulation formula is shown in figure 1 and comprises a cell shell 1 and a cell cover plate 2 which is arranged above the cell shell 1 and is correspondingly embedded and fixed with the cell shell 1. Through holes 21 for respectively accommodating the anode cylinder 1414 and the cathode cylinder 1424 are formed on the diagonal corners of the battery cover plate 2.

As shown in fig. 2, the battery case 1 includes a case 11, the case 11 is divided into a plurality of cavities 12 with the same volume and filled with deep circulation formula liquid by partition boards, and a sealing plate 13 disposed on the cavities 12 and used for sealing the cavities 12, the battery case 1 further includes a grid assembly 14 mounted in the cavities 12, and a metal rod 15 disposed outside the case 11 and connected to the grid assembly 14 in two adjacent cavities 12, and two ends of the metal rod 15 are provided with pole collars 151 for connecting the grid assemblies 14 in two adjacent cavities 12.

As shown in fig. 3-4, the grid assembly 14 includes a positive lead dioxide plate 141, and negative sponge lead plates 142 disposed on both sides of the positive lead dioxide plate 141 and sandwiching the positive lead dioxide plate 141. The positive lead dioxide plate 141 comprises a lead dioxide plate body 1411, a positive lug 1412 integrally formed above one end of the lead dioxide plate body 1411, a positive lug support plate 1413 transversely placed on the positive lug 1412 and integrally formed with the positive lug 1412, and a positive post 1414 welded and fixed with the positive lug support plate 1413. The negative spongy lead plate 142 includes two spongy lead plate bodies 1421 parallel to each other, a negative tab 1422 integrally formed above one end of the spongy lead plate body 1421, a negative tab supporting plate 1423 integrally formed with the negative tab 1422 at both ends and used for connecting the two spongy lead plate bodies 1421, and a negative pole cylinder 1424 welded and fixed with the negative tab supporting plate 1423.
