Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic energy storage equipment, and in particular to an outdoor photovoltaic energy storage equipment. Background Art

[0002] Photovoltaic energy storage, also known as solar photovoltaic energy storage system, is a way of energy utilization that combines solar photovoltaic power generation with energy storage technology. It converts solar energy into electrical energy through photovoltaic panels, and uses energy storage equipment (such as battery packs) to store this electrical energy so that it can supply electricity when needed. Energy storage batteries are generally installed in energy storage cabinets similar to containers, and are generally placed outdoors for energy storage.

[0003] It should be noted that the shell of the energy storage cabinet is generally made of a single-layer metal material, which makes the use environment of the energy storage battery extremely susceptible to the influence of the external temperature. Photovoltaic energy storage is generally installed outdoors with a long light time. Therefore, if it is exposed to sunlight for a long time and the external temperature rises, the temperature inside the energy storage cabinet will be high for a long time. At the same time, the energy storage battery itself will also generate a lot of heat when in use. Therefore, the superposition of multiple heat makes it impossible to guarantee the use environment of the energy storage battery. It is very easy for the energy storage battery to be unusable or even cause fire and explosion due to overheating, posing a safety hazard. In addition, since the energy storage cabinet is located outdoors for a long time, it is affected by wind and sun, which makes it easy for impurities such as soil to adhere to the outside of the energy storage cabinet, making it more difficult for the energy storage cabinet to dissipate heat.

[0068] During normal use of the energy storage battery 2, the vacuum energy storage cabinet 1 and the side panels 3 can play a good role in heat insulation, effectively reducing the impact of high temperature outside on the energy storage battery 2. At the same time, by starting multiple circulating fans 702, the cold air in the bottom heat sink 5 is blown into the energy storage cabinet 1, so as to achieve the purpose of cooling the energy storage battery 2 by the cold air underground, thereby ensuring the stability of the operating environment of the energy storage battery 2.

[0069] However, when an overload or other accident occurs, causing the temperature in the energy storage cabinet 1 to rise abnormally, the air temperature in the expansion box 606 rises rapidly, and then the expansion plate 607 swells rapidly, and then the switch 608 is squeezed to open the cylinder 604, and the cylinder 604 drives the drive gear rack 605 to move, so that the drive gear rack 605 drives the two extension gears 602 to rotate, and the extension gear 602 drives the extension rotating rod 601 to rotate through the rotating shaft 603, and the extension rotating rod 601 drives the side plate 3 to slide and unfold through the extension sliding shaft 610, and the extension sliding shaft 610 slides in the extension sliding groove 609, and the side plate 3 slides horizontally in the limiting bar 611 through the telescopic sliding rod 612, so that the side plate 3 drives the multiple energy storage batteries 2 to move to the outside of the energy storage cabinet 1 through the multiple placement partitions 4, so as to perform sufficient heat dissipation;

[0070] Furthermore, when the multiple placement partitions 4 move, the placement partition 4 located at the bottom no longer squeezes the flip plate 701, and then under the rotational force of the two reset torsion springs 705, the two reset torsion springs 705 drive the two reset shafts 704 to rotate, so that the flip plate 701 is flipped to a vertical state. At this time, the multiple energy storage batteries 2 are assisted in heat dissipation by the blowing of the multiple circulation fans 702, and the heat dissipation effect is further enhanced. When the flip plate 701 no longer squeezes the extrusion rod 709, under the pull-back force of the two pull-back springs 711, the container frame 708 drives the multiple sealing plates 707 to close the multiple circulation holes 706, so as to prevent external impurities from entering the bottom heat dissipation box 5 and affecting the use of the bottom heat dissipation box 5.

[0071] Furthermore, during the use of the energy storage cabinet 1, since the energy storage cabinet 1 is outdoors, it is affected by wind and sun, so that a large amount of impurities will condense on the top side and the two side panels 3 of the energy storage cabinet 1, thereby making the heat dissipation effect of the outer side of the energy storage cabinet 1 poor, which easily causes the problem of overheating of the outer side of the energy storage cabinet 1. Therefore, through natural blowing, the multiple driving blades 812 are driven to rotate, and the driving blades 812 drive a bevel gear 813 to rotate through the rotating rod 811, and the rotation of one bevel gear 813 drives another bevel gear 813 to rotate, thereby driving the driving column 805 to rotate, and the driving column 805 drives the rotating rod 811 to rotate. The driving groove 807 drives the driving block 808 to move, and the driving block 808 drives the top scraper 802 to move. The top scraper 802 slides in the sliding hole 810 through the sliding block 809, thereby achieving the purpose of moving the top scraper 802 back and forth once when the driving column 805 rotates one circle, and then the top scraper 802 drives the two side scrapers 804 to move through the two synchronous telescopic rods 803, so as to scrape off the impurities on the top side and the two side panels 3 of the energy storage cabinet 1, avoid too much impurity condensation, and cause the top side and the two side panels 3 of the energy storage cabinet 1 to overheat, and further ensure the use environment of the energy storage battery 2.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
