Description

Technical Field

[0001] The utility model relates to an energy storage bag and belongs to the technical field of photovoltaic power generation. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters. The main components are made of electronic components. In the process of photovoltaic power generation, since the radiation intensity of sunlight is not constant, photovoltaic power generation is intermittent and uncertain. At the same time, electricity consumption also has day and night and seasonal differences. Therefore, in order to effectively balance the mismatch between power generation and consumption, reduce the pressure on the power grid, collect and store excess electricity generated by solar energy under high illumination conditions, energy storage packages are needed to release the stored electricity on cloudy days, at night or when demand increases.

[0003] Authorization announcement number (CN213459924U) discloses an energy storage battery pack, including multiple batteries, a shell, a separator and a buffer plate; multiple batteries are arranged in an array in the shell, the wider side of the batteries in the same row are arranged opposite to each other and leave a certain gap, and the separator is arranged in the gap between the multiple batteries to keep the multiple batteries at a distance; the separator is fixedly connected to the shell and pressed against the upper surface of the battery; one side of the buffer plate is fixedly connected to the inner wall of the shell, and the other side abuts against the wider side of the battery arranged near the inner wall of the shell; when the battery expands, it is mainly the wider side that expands, so when installing, a certain gap is left between the wider sides of the battery, and a separator is set. The buffer plate is a "J"-shaped curved plate. When the battery expands, the buffer plate can offset it through its own deformation to prevent the shell from being squeezed due to battery expansion, resulting in damage to the shell.

[0004] However, the above technology may have poor safety protection effect during use. During use, if there is an unexpected external collision or if there is a lack of protective structure, the energy storage unit will be easily damaged when it is subjected to physical impact. This physical damage may cause the internal battery structure to deform or rupture, and then cause a battery short circuit, thereby increasing the risk of overheating and fire, which will not only shorten the service life of the energy storage system, but may also cause significant property losses and threats to personal safety.

[0005] To this end, an energy storage package is proposed. Utility Model Content

[0027] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-6 As shown, the embodiment of the utility model provides an energy storage pack, including an energy storage pack shell 1, the inner cavity of the energy storage pack shell 1 is provided with a mounting frame 2, the left and right sides of the mounting frame 2 are fixedly installed with a bottom plate 3, the surface of the bottom plate 3 is threadedly connected with a first bolt 4, the bottom plate 3 is connected to the bottom of the inner cavity of the energy storage pack shell 1 through the first bolt 4, the surface of the energy storage pack shell 1 is provided with a protective mechanism 5, the protective mechanism 5 includes a connecting box 501, a slide bar 502, a spring 503, a slider 504, a first connecting block 505, a connecting plate 506, a second connecting block 507, and a through groove 508. , mounting plate 509 and second bolt 510, the connection box 501 is fixedly installed on the left and right sides of the surface of the energy storage package shell 1, the through groove 508 runs through the left and right sides of the inner cavity of the energy storage package shell 1, the slide bar 502 is fixedly connected to the inner side of the two connection boxes 501, the slider 504 is slidably connected to the upper and lower sides of the surface of the two slide bars 502, the first connection block 505 is fixedly connected to the inner side of the surface of the two sliders 504, the connection plate 506 is movably connected to the inner side of the two first connection blocks 505 through a rotating shaft, and the second connection block 507 is movably connected to the other end of the two connection plates 506.

[0030] By providing the protection mechanism 5, the safety and reliability of the system can be improved. The spring 503 can effectively absorb and disperse the force generated by external impact, thereby protecting the internal battery from damage, helping to prevent deformation and rupture of the battery structure, reducing the risk of short circuit and overheating, and further reducing the possibility of fire.

[0031] Example 2

[0032] In one embodiment, a spring 503 is fixedly connected to the inner side of a slider 504, and the spring 503 is located on the outer sides of two slide bars 502. Bolt holes 6 are provided on the left and right sides of the surface of the energy storage package shell 1. A mounting plate 509 is arranged on the left and right sides of the mounting frame 2. A second bolt 510 is threadedly connected to the four mounting plates 509 around the surface. The mounting plates 509 are threadedly connected to the mounting frame 2 through the second bolt 510. Guide grooves 7 are provided on the front and rear sides of the inner cavity of the connection box 501. Guide blocks 8 are fixedly installed on the surfaces of the four sliders 504. Eight guide blocks 8 are slidably connected to the inner sides of the eight guide grooves 7. A heat dissipation fan 13 is fixedly installed around the front side of the energy storage package shell 1. A dust cover 9 is threadedly connected around the front side of the energy storage package shell 1. A ventilation net 10 is fixedly installed on the rear side of the energy storage package shell 1. A heat dissipation groove 11 is provided at the bottom of the energy storage package shell 1. Support pads 12 are fixedly installed on the left and right sides of the bottom of the energy storage package shell 1.

[0033] By setting the second bolt 510 and the bolt hole 6, when the mounting frame 2 needs to be disassembled, the connection between the mounting plate 509 and the second connecting block 507 can be released, so as to facilitate disassembly and subsequent installation. The setting of the guide block 8 and the guide groove 7 can play a guiding role to prevent the slider 504 from deviating during movement. The setting of the heat dissipation fan 13 can improve the thermal effect of the battery inside the energy storage pack shell 1. The setting of the dust cover 9 can filter dust. The setting of the heat dissipation groove 11 can ensure that the air at the bottom of the energy storage pack shell 1 can circulate. The bottom of the energy storage pack shell 1 can be supported by the support pad 12.

[0034] When the utility model is in operation: after the bottom plate 3 and the mounting frame 2 are fixed to the inner cavity of the energy storage bag shell 1 by the first bolt 4, the energy storage battery can be inserted into the inner groove of the mounting frame 2. During use, the heat dissipation fan 13 drives air circulation to improve the heat dissipation effect of the battery inside the mounting frame 2. When an unexpected collision occurs outside, the mounting frame 2 shakes and applies pressure to the outside. Under the influence of the squeezing of the mounting frame 2, the mounting plate 509 moves outward. When the mounting plate 509 moves, it drives the second connecting block 507 to move outward. When the second connecting block 507 moves, it drives the connecting plate 506, the first connecting block 505 and the slider 504 to move inward along the surface of the slide rod 502. When the slider 504 moves, it squeezes the spring 503, causing the spring 503 to be compressed and deformed, thereby absorbing the force generated by the vibration.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
