Example

[0038] Reference Figures 1 to 4 In order to solve the technical problems that the existing photovoltaic energy storage boxes have low safety performance and cannot protect the equipment batteries, the utility model provides a photovoltaic energy storage box, which includes: a chassis 1, a cover 2, a fireproof board 3 and a protective mechanism 5. The cover 2 is plugged into the top of the chassis 1. The fireproof board 3 is fixedly arranged inside the chassis 1, and the fireproof board 3 is in a horizontal L shape. A battery cavity 4 is formed inside the chassis 1 by the arrangement of the fireproof board 3. The interior of the chassis 1 is divided into two independent spaces by the fireproof board 3, thereby protecting the mechanisms in each space through the material characteristics of the fireproof board 3, especially the batteries inside the battery cavity 4. The inner wall of the battery cavity 4 is provided with a slide groove 41. The protective mechanism 5 is arranged in the battery cavity 4.

[0039] Specifically, the protection mechanism 5 includes: a mounting portion 51 and a control portion 52. The mounting portion 51 is slidably disposed in the battery cavity 4 through the slide groove 41 for the installation of the battery. The control portion 52 is fixedly disposed at the bottom of the battery cavity 4. Among them, the control portion 52 includes: an electric control push rod 521 and a lifting plate 522. The electric control push rod 521 is fixedly disposed at the inner bottom of the battery cavity 4. In order to realize the control of the vertical height of the mounting portion 51 by the electric control push rod 521, specifically, in case of fire, the connection between the battery in the mounting portion 51 and the equipment can be cut off by lowering the height, thereby achieving the effect of protecting the battery. The lifting plate 522 is fixedly disposed at one end of the piston rod of the electric control push rod 521, and the mounting portion 51 can be placed on the lifting plate 522. It should be added that a temperature sensing device 6 (specifically, the model is HDA420, which has high precision and reliability, is easy to install, and can also measure temperature quickly and accurately) is embedded on the top of the fireproof board 3. The temperature sensing device 6 is wirelessly connected to the electric control push rod 521, thereby realizing the detection of temperature by the temperature sensor and transmitting the signal to the control terminal of the electric control push rod 521, thereby achieving the effect of controlling the extension and retraction of the electric control push rod 521. In this embodiment, the chassis 1 is divided into two independent spaces by the installation of the fireproof board 3, one of which is the battery cavity 4 where the battery is installed, and the battery is installed in the installation part 51 in the protection mechanism 5 and stored above the control part 52. In addition, by setting the temperature sensing device 6, it can respond quickly in the event of fire and high temperature, and control the electric control push rod 521 in the control part 52 to quickly fall, thereby cutting off the cable connection between the battery and the device, thereby achieving the effect of protecting the battery.

[0040] Please refer to Figure 1 and Figure 3As shown, in this embodiment, the mounting portion 51 includes: a protection box 511, a door body 512 and an opening 513. The material of the protection box 511 is the same as that of the fireproof board 3 to ensure the protection performance of the battery. One side of the protection box 511 is open, and the protection box 511 is slidably arranged in the battery cavity 4. The protection box 511 is slidably connected to the slide groove 41 to facilitate the user to install the protection box 511 through the design of the slide groove 41, and the protection box 511 can also avoid shaking during use in the slide groove 41, thereby increasing the protection performance of the device. The door body 512 is hinged to a side opening of the protection box 511, and the hinged door body 512 facilitates the user to place the battery into the protection box 511. The opening 513 is opened at the top of the protection box 511. It should be added that a reserved hole 31 is provided on the outer wall of one side of the fireproof plate 3 located inside the battery cavity 4. The reserved hole 31 is used for the cable of the equipment in the chassis 1 to pass through, so that the cable can enter the battery cavity 4 through the reserved hole 31, and pass through the opening 513 at the top of the protective box 511 to connect with the battery. Similarly, when the electric control push rod 521 drives the protective box 511 to descend in height, the cable will be separated from the battery inside the protective box 511, thereby achieving the effect of protecting the battery.

[0041] In a feasible embodiment, in order to prevent the battery inside the protection box 511 from being damaged due to over-high operating temperature, a cooling fan 514 is fixedly provided on the side of the protection box 511 away from the opening, and a heat dissipation groove 515 is provided on the outer wall of one side of the protection box 511, and the heat dissipation groove 515 is close to the heat dissipation fan 514. A heat dissipation plate 7 is embedded on one side of the chassis 1, so that the temperature inside the battery cavity 4 and the protection box 511 can be transmitted to the outside of the chassis 1 through the heat dissipation plate 7, thereby achieving a heat dissipation effect.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
