Technical Field

[0001] The utility model relates to the technical field of energy storage devices, in particular to an energy storage device for photovoltaic power generation. Background Art

[0002] Entering the new century, photovoltaic power generation has gradually become the focus of everyone's attention. Photovoltaic power generation is a power generation method that converts solar radiation into electrical energy through photovoltaic cells. A typical photovoltaic power generation system consists of photovoltaic panels, controllers, cables, and power storage and conversion links. The electrical energy generated by photovoltaic cells is stored and converted through cables, controller energy storage and other links, and converted into electrical energy that can be used by the load;

[0003] At present, most of the energy storage batteries used in photovoltaic power generation are directly fixed in the box for protection. When some of the energy storage batteries are aged, it is more laborious for the staff to dismantle and replace the aged energy storage batteries, which makes it inconvenient for the staff to replace the aged energy storage batteries. At the same time, there is no buffering and shock-absorbing equipment inside the box, which makes the energy storage batteries easily damaged by vibration during transportation and movement, reducing the service life. Utility Model Content

[0004] The utility model aims to provide a photovoltaic energy storage device, which has good shock absorption effect, avoids vibration damage to the photovoltaic power generation device, prolongs the service life, and is easy to disassemble, saves time and effort, and is convenient for maintenance and replacement.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a photovoltaic power generation energy storage device, comprising an outer shell and a photovoltaic power generation device located on the top of the outer shell, a mounting frame is arranged inside the outer shell, an energy storage group unit is installed inside the mounting frame, a base is fixedly connected to the inner bottom end of the outer shell, a mounting plate is arranged above the base, a damping shock absorber is installed at the center position between the mounting plate and the base, a fixing cylinder is fixedly connected to the left and right sides of the lower end surface of the mounting plate, a buffer rod is movably connected to the inside of the two fixing cylinders, a buffer spring is fixedly connected between the two buffer rods and the inner top of the fixing cylinder, a positioning plate is fixedly connected to the bottom ends of the two buffer rods, and a positioning groove matching the positioning plate is fixedly connected to the left and right sides of the upper end surface of the base;

[0006] Through slots are provided on both sides of the upper end surface of the mounting plate, and four legs are fixedly connected to the bottom of the mounting frame. The two legs located on the same side in the left and right directions extend to the bottom of the mounting plate through the same through slot, and the bottom ends of the four legs are rotatably connected to rollers. Four cylinders are installed on the upper end surface of the base, and the output ends of the two cylinders located on the same side in the left and right directions are fixedly connected to a top plate.

[0007] In order to protect and disassemble the photovoltaic power generation device, as a preferred photovoltaic power generation energy storage device of the utility model, the front end surfaces of the two mounting plates are movably connected with a protective plate through a hinge.

[0008] In order to facilitate the disassembly and assembly of the photovoltaic power generation device, as a preferred photovoltaic power generation energy storage device of the utility model, the front end surface of the shell is provided with a double-opening door body.

[0009] In order to facilitate heat dissipation, as a preferred photovoltaic power generation energy storage device of the utility model, a plurality of evenly distributed heat dissipation windows are provided on both left and right sides of the outer wall of the shell.

[0010] In order to facilitate the top plate to extend into the through groove, as a preferred photovoltaic power generation energy storage device of the utility model, the width of the top plate is smaller than the width of the through groove.

[0011] In order to limit the position of the mounting plate, as a preferred photovoltaic power generation energy storage device of the utility model, telescopic cylinders are provided on both left and right sides between the mounting plate and the base.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The energy storage unit is installed on the inner side of the mounting frame, and the mounting frame is placed on the upper end of the mounting plate. When it is vibrated during transportation, the damping shock absorber first absorbs and buffers most of the vibration force to effectively reduce the vibration. The vibration force drives the mounting plate to move downward, so that the positioning plate extends to the inside of the positioning groove. At this time, the buffer rod squeezes the buffer spring, and the buffer spring further absorbs and buffers the vibration force to improve the shock absorption effect, thereby making the energy storage unit more stable, avoiding vibration damage, and extending the service life;

[0014] When the energy storage unit needs to be disassembled, the four cylinders are started to drive the top plates on both sides to move upward. After the two top plates abut against the four rollers, the rollers are continuously lifted upward until the two top plates extend to the inner sides of the two through grooves and the upper end surfaces are flush with the upper end surfaces of the mounting plates. At this time, the four rollers are all located on the upper end surfaces of the mounting plates. The protective plates are then laid forward, and the front side of the protective plates overlaps the ground to form a slope, so that the mounting frame and the energy storage unit can be pulled out of the casing as a whole, which is convenient for disassembly, saves time and effort, and is convenient for maintenance and replacement.
