The utility model relates to the technical field of lithium battery fire extinguishing devices, in particular to a portable lithium battery fire extinguishing device which comprises a cart and a fire extinguishing device, a hoop for fixing the fire extinguishing device is mounted on the trolley; the fire extinguishing device is dragged by the cart to move and comprises a fire extinguishing device bottle body, a valve, a spray pipe, a spray rod and a nozzle, the spray rod is of a rigid hollow rod body structure and is communicated with the spray pipe, an ergonomic bend is designed at the tail end of the spray rod to facilitate aiming, an insulating rubber grip is designed on the spray rod, and the electric shock risk of fire extinguishers during lithium battery fire extinguishment is reduced; the spray nozzle sprays out fire extinguishing agents outwards, the spray nozzle is an atomizing spray nozzle, the electric conduction and electric shock risks are effectively reduced, by adopting the technical scheme that the cart and the spray rod are combined, the large-size and large-mass fire extinguisher can be conveniently carried, meanwhile, centralized fire extinguishing treatment can be conducted on a fire source of a lithium battery, waste of the fire extinguishing agents is avoided, and the fire extinguishing efficiency is improved. Meanwhile, the spraying time of the fire extinguishing agent on lithium battery fire extinguishing is prolonged.

The utility model relates to the technical field of photovoltaic frame feeding, and particularly discloses an automatic feeding mechanism for frame pieces, which comprises a portal frame, and a lifting assembly is connected onto the portal frame in a sliding manner; the clamping assembly is connected to the lower portion of the lifting assembly, and the multiple frame pieces are vertically arranged on the multiple filler strips in an attached mode. The clamping assembly comprises a first frame connected with the lifting assembly, a first connecting arm and a second connecting arm which are matched with the filler strip are movably arranged on the first frame, and the clamping assembly clamps / loosens the filler strip through the first connecting arm and the second connecting arm which are movably arranged on a connecting frame; the lifting assembly drives the clamping assembly to ascend and descend on the portal frame through the lifting base, so that the clamping assembly conveys the frame piece on the filler strip to the third sliding table from the first sliding table.
