Description

Stacked energy storage device battery pack plug-in structure convenient to expand Technical Field The utility model belongs to the technical field of battery plug-in structures, and particularly relates to a battery pack plug-in structure of a stacked energy storage device, which is convenient to expand. Background The modularized stacked battery pack is formed by vertically or horizontally stacking a plurality of standardized sub-modules, each module is independently packaged, and voltage and capacity requirements are achieved through series-parallel connection. Chinese patent publication No. CN217903332U, which issued 2022, 11, 25. The utility model discloses a battery package stack structure of combination formula energy storage equipment, this application includes the battery package of the upper and lower superpose more than at least, and the lower part that is located the first battery package of upper strata is equipped with slide groove mechanism, and the pulley buckle mechanism that matches with slide groove mechanism locates the top of the second battery package of the downside of first battery package, and slide groove mechanism and pulley buckle mechanism are used for first battery package and second battery package to fold lock or first battery package and second battery package to fold and disconnect. The sliding groove mechanism comprises a sliding rail and a positioning mechanism, and the pulley buckle mechanism comprises a pulley block and a buckle spring assembly. After the first battery pack and the second battery pack are stacked, the first battery pack or the second battery pack can be lifted to move. The battery pack stacking structure can improve battery pack carrying efficiency, save carrying time, solve the problem of external arbitrary expansion of energy storage box products, and have good product flexibility The conventional electrolyte of the battery pack plug-in structure suddenly drops below-10 ℃ in ionic conductivity, so that the discharge capacity is attenuated by more than 30%, the commonly used IP67 protection is difficult to cope with a sand storm or flood soaking scene, the problem that the interface is easy to age and lose efficacy can occur, and the conventional battery pack plug-in structure has the defects of poor low-temperature performance, dust prevention and water prevention limitation. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a stacked energy storage device battery pack plugging structure which is convenient to expand, and pollutants in the guide groove can be scraped through the sliding type scraping blade plugging guide groove, so that the problems in the background are solved. The utility model is realized by the following technical scheme that the battery pack plug-in structure of the stacked energy storage device convenient to expand comprises a plug and a socket, wherein the plug is provided with a fixed seat, the front end of the fixed seat is provided with a metal head, two sides of the metal head are provided with sliding type scraping blades, a spring is arranged between the bottom of the sliding type scraping blades and the fixed seat, the rear end of the fixed seat is connected with a first connecting wire, the socket is provided with a base, the front end of the base is provided with a guide groove matched with the sliding type scraping blades, and the rear end of the base is connected with a second connecting wire. Preferably, the periphery of fixing base and base is covered with the silica gel shell, is provided with annular rubber circle on the contact surface of fixing base and base. Preferably, the front end periphery of fixing base is provided with the protection casing, and the protection casing sets up around the metal head and matches with the base periphery slip. Preferably, a buckle is arranged on one side of the plug, and a clamping groove matched with the buckle is arranged on one side of the socket. Preferably, the contact surfaces of the fixing seat and the base are provided with magnet blocks. Preferably, the fixing base and the space between the base and the silica gel shell are filled with hydrophobic gel. Preferably, the outside of the sliding wiper blade is impregnated with molybdenum disulfide. Preferably, the surface of the metal head is coated with a nickel layer and a graphene coating. Compared with the prior art, the scraper has the beneficial effects that pollutants in the guide groove can be scraped through the sliding scraper inserted into the guide groove, and the manual maintenance frequency is reduced. The silica gel shell and the hydrophobic gel are matched to realize composite sealing through the annular rubber ring, so that long-term waterproof and dustproof effects are realized. The magnetic attraction and the buckle cooperatively promote the operation safety. Additional aspects and advantages of the utility model will be set forth in part in the description whi
