[0002] Wind and solar energy storage lithium battery packs refer to energy storage devices used in wind and solar power generation systems. They mainly include lithium battery packs for energy storage and external components of the battery packs, which are mainly composed of multiple lithium battery cells. These lithium battery cells can store electrical energy and release energy when needed, realizing the storage and regulation of electrical energy. However, some wind and solar energy storage lithium battery packs are currently arranged in outdoor scenes such as hillsides and highlands, and are easily affected by the environment during use.

[0003] Specifically, it manifests itself in the following aspects: 1. Temperature difference: The wind and solar energy storage lithium battery packs on the hillside may be affected by extreme climate, such as storms, lightning, hail and other low-temperature weather, which may damage the battery pack or affect its normal operation, or encounter high temperature, exposure to the sun, etc., which will also affect the performance and life of the battery pack;

[0004] 2. Humidity influence: In high humidity environments such as rainy days, rain or dew will flow into the battery pack through the heat dissipation holes on the battery pack shell, causing damage such as corrosion and rust to the battery pack, resulting in performance degradation and shortened life.

[0005] Therefore, there is an urgent need for a wind and solar energy storage lithium battery pack to solve the problems arising from the above-mentioned background technology. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] like Figure 1 to Figure 6A wind-photovoltaic energy storage lithium battery pack shown includes a fixed shell 1. In a specific embodiment, a plurality of heat dissipation holes 2 are opened on the four sides of the fixed shell 1. The heat dissipation holes 2 are opened in a downward slanting shape from the inside to the outside. The heat inside the battery pack body 9 is discharged through the heat dissipation holes 2 to facilitate heat dissipation.

[0027] like Figure 1 to Figure 6 A wind-photovoltaic energy storage lithium battery pack is shown, and a specific embodiment is that a base 3 is fixedly welded to the bottom of a fixed outer shell 1, and fixed legs are respectively welded to the four corners of the lower end of the base 3. A bottom cavity 4 is opened in the base 3, and a rotating fan 5 is fixedly connected to the bottom cavity 4. The upper end of the bottom cavity 4 is connected to four ventilation ducts 6, and each ventilation duct 6 is provided with a plurality of ventilation holes 7. The rotating fan 5 passes wind through the ventilation duct 6 into the fixed inner shell 8, so as to facilitate the heat dissipation of the battery pack.

[0028] like Figure 1 to Figure 6 A wind-photovoltaic energy storage lithium battery pack is shown in a specific embodiment, in which a fixed inner shell 8 located inside a fixed outer shell 1 is fixedly connected to a base 3, a battery pack body 9 is fixedly connected inside the fixed inner shell 8, and a ventilation duct 6 is located inside the fixed inner shell 8 and is respectively located in the middle of the sides of the battery pack body 9.

[0029] like Figure 1 to Figure 6 A wind and photovoltaic energy storage lithium battery pack is shown, in a specific embodiment, a plurality of strip holes 10 in the vertical direction are opened on the sides of the fixed inner shell 8, and the heat on the battery pack body 9 is discharged to the fixed outer shell 1 through the strip holes 10. The outer side of the fixed inner shell 8 is provided with a closed shell 11 corresponding to the strip holes 10 one by one. A gap is opened between the fixed outer shell 1 and the fixed inner shell 8, and the closed shell 11 can slide in the gap. The inside of the closed shell 11 is fixedly connected with a water-absorbing sponge 12 that can seal the strip holes 10. The fixed outer shell 1 A top shell 13 is fixedly connected to the upper end, a temperature sensor 14 is fixedly connected to the middle part of the lower end of the top shell 13, and a heating module 18 is fixedly connected to the rotating fan 5. When the temperature is too low, the temperature sensor 14 drives the heating module 18 to heat up through the control panel 20, the rotating fan 5 rotates, and the hot air enters the fixed inner shell 8 through the ventilation duct. When the temperature is too high, the control panel 20 controls the closed shell 11 to move, and connects the strip hole 10 with the outside world, thereby accelerating the heat dissipation inside the fixed inner shell 8 and improving the battery performance of the battery pack.

[0030] like Figure 1 to Figure 6A wind and photovoltaic energy storage lithium battery pack is shown, and a specific embodiment is that the upper end of the closed shell 11 is opened in a wedge shape, and four upper and lower axial rotating screws 15 are rotatably connected to the base 3 and are respectively located around the base 3, and a sliding block 16 that can slide up and down is threadedly connected to the rotating screw 15, and the sliding block 16 is slidably connected to the top shell 13, and the lower end of the sliding block 16 and the closed shell 11 on the corresponding side can slide relatively, and the upper end of the top shell 13 is fixedly connected to a driving motor 17 corresponding to the rotating screw 15 one by one. Specifically, the driving motor 17 drives the rotating screw 15 to rotate, and the rotating screw 15 drives the sliding block 16 to slide downward, and the sliding block 16 drives the closed shell 11 to move.

[0031] By closing the shell 11 and the absorbent sponge 12, when encountering a high humidity environment such as a rainy day, when rain or dew enters between the fixed outer shell 1 and the fixed inner shell 8, the absorbent sponge 12 absorbs the moisture. At the same time, by starting the rotating fan 5 and the heating module 18, the absorbent sponge is dried, which is beneficial to protecting the battery pack main body 9.

[0032] like Figure 1 to Figure 6 A wind and photovoltaic energy storage lithium battery pack is shown, and a specific embodiment is that a cover plate 19 is fixedly connected to the upper end of the top shell 13, and a control panel 20 is fixedly connected inside the cover plate 19. The control panel 20 is electrically connected to the drive motor 17, the battery pack body 9, the rotating fan 5, and the temperature sensor 14, so as to facilitate the setting of the operating parameters of each component.

[0033] like Figure 1 to Figure 6 A wind-photovoltaic energy storage lithium battery pack is shown, in a specific embodiment, a return compression spring 21 is fixedly connected between the closed shell 11 and the fixed shell 1 on the corresponding side thereof.

[0034] The working principle of the device is as follows: when the device is in use, when the temperature is too low, the temperature sensor 14 drives the heating module 18 to heat up through the control panel 20, the rotating fan 5 rotates, and the hot air enters the fixed inner shell 8 through the ventilation duct. When the temperature is too high, the control panel 20 controls the driving motor 17 to rotate, the driving motor 17 drives the rotating screw 15 to rotate, the rotating screw 15 drives the sliding block 16 to slide downward, and the sliding block 16 drives the closed shell 11 to move, so that the water-absorbing sponge 12 and the strip hole 10 are out of sealing. At this time, the strip hole 10 is connected with the outside world, thereby accelerating the heat dissipation inside the fixed inner shell 8.

[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
