[0002] The battery is an important component of the photovoltaic energy storage system. In the prior art, most batteries are installed in boxes or board houses on the ground.

[0003] In order to solve the above problems, some people have proposed to bury the battery underground. However, in the burying scheme adopted in the prior art, the heat generated during the charging and discharging process of the battery cannot be dissipated in time and fully, which has an adverse effect on the charging and discharging efficiency and service life of the battery. Therefore, it is necessary to design a new type of battery burying scheme. Utility Model Content

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] like Figure 1 As shown, this embodiment includes a bottom plate 4, a side wall plate 3 and a cover plate 2. The side wall plate 3 forms a cylindrical structure, the bottom plate 4 is welded to the bottom of the cylindrical structure, and the cover plate 2 is connected to the edge of the top of the cylindrical structure by bolts, thereby forming a box body for accommodating the battery 7. During implementation, the box body needs to be sealed to achieve the purpose of waterproofing and moisture-proofing.

[0025] like Figure 1 As shown, the upper side of the cover plate 2 is connected with a threading tube 1, which leads upward to the ground and communicates with the internal space of the box downward. The basic function of the threading tube 1 is to facilitate the wiring of the battery 7. During implementation, the length of the threading tube 1 is preferably sufficient to ensure that the top of the box is two meters underground, so that the temperature of the environment where the battery 7 is located is more constant.

[0026] like Figure 1 , 3 As shown in Figures 4 and 5, in this embodiment, the tube wall of the threading tube 1 is a double-layer structure, and the two layers of the tube wall are respectively called the inner tube wall 11 and the outer tube wall 9. A heat dissipation channel is provided between the inner tube wall 11 and the outer tube wall 9, which is called the inner tube heat dissipation channel 10. The direction of the inner tube heat dissipation channel 10 is consistent with the axial direction of the threading tube 1. At the same time, a heat dissipation channel is also provided in the box, which is called the inner box heat dissipation channel 8. By connecting the inner tube heat dissipation channel 10 with the inner box heat dissipation channel 8, the heat in the box can be dissipated to the ground. This is the basic principle of heat dissipation achieved by the utility model.

[0027] In this embodiment, the specific configuration of the heat dissipation channel 8 in the box is as follows:

[0028] like Figure 1 , 2 As shown, partitions 5 are provided on the top, bottom and inner sides of the left and right side wall plates 3 of the box body, the battery 7 is placed in the space surrounded by the partitions 5, and the heat dissipation channel 8 in the box is provided between the partitions 5 and the box body.

[0029] like Figure 1 , 4 As shown, the inner tube wall 11 of the threading tube 1 is connected to the partition 5 on the inner side of the cover plate 2 and communicates with the space inside the partition 5. The outer tube wall 9 of the threading tube 1 is connected to the cover plate 2, so that the heat dissipation channel 10 in the tube is connected with the heat dissipation channel 8 in the box.

[0030] like Figure 1 ,2 As shown, the partition 5 corresponding to the bottom plate 4 is densely covered with ventilation holes, and the inner space of the partition 5 where the battery 7 is located is connected to the heat dissipation channel 8 in the box through the ventilation holes;

[0031] like Figure 1 , 4 As shown, an air pump 12 is connected to the outer side of the upper end of the threading tube 1, and the inlet end of the air pump 12 is connected to the heat dissipation channel 10 in the tube. The function of the air pump 12 is to generate negative pressure to facilitate heat dissipation. In specific implementation, a fan can also be used to provide negative pressure.

[0032] like Figure 1 As shown, in this embodiment, in order to ensure the sealing effect between the cover plate 2 and the box body, a rubber plate is provided at the connection between the cover plate 2 and the upper edge of the side wall plate 3, and the rubber plate is clamped between the cover plate 2 and the upper edge of the side wall plate 3, thereby achieving sealing at the connection.

[0033] like Figure 1 , 4 As shown, the threading tube 1 is divided into a horizontal section and a vertical section, and the two are connected by a 90-degree elbow.

[0034] As a preferred solution, the threading tube 1 is a rigid tube, which is conducive to ensuring the stability of the shape of the threading tube 1 and facilitating threading. During implementation, a steel tube can be selected as the threading tube 1, and the steel tube can be directly welded to the cover plate 2 which is also made of steel, which is conducive to ensuring the sealed connection between the threading tube 1 and the cover plate 2.

[0035] like Figure 2 As shown, there are at least two heat dissipation channels 8 in the box, and each heat dissipation channel 8 is arranged in parallel to make the heat dissipation more uniform and more efficient.

[0036] Working principle:

[0037] During operation, the entire box is buried below the ground, and the upper end of the threading tube 1 is exposed to the ground. After the battery 7 enters the working state, the air pump 12 is started. The negative pressure generated by the operation of the air pump 12 causes negative pressure to be generated in the heat dissipation channel 10 in the tube, the heat dissipation channel 8 in the box, the inner space of the partition 5 where the battery 7 is located, and the central channel of the threading tube 1. The negative pressure forces the hot air around the battery 7 to enter the heat dissipation channel 8 in the box at the bottom of the box through the vent 6, and then enter the heat dissipation channel 10 in the tube through the side wall and the top of the box. Then, it is discharged into the air through the air pump 12. At the same time, the outside air enters the space where the battery 7 is located from the central channel of the threading tube 1, and the air flows to the following directions: Figure 1 As shown by the arrow in the middle, the heat around the battery 7 is continuously carried to the external space through the flow of air in the box and the threading tube 1, thereby effectively ensuring heat dissipation.
