A punching-free lap joint walking channel for a photovoltaic panel cleaning robot belongs to the technical field of photovoltaic equipment and comprises outer side connecting pieces and U-shaped steel, the outer side connecting pieces are arranged on the left side and the right side of the opposite side faces of adjacent photovoltaic panels and inserted into the side edges of the adjacent photovoltaic panels, and the U-shaped steel is arranged on the left side and the right side of the adjacent photovoltaic panels and inserted into the side edges of the adjacent photovoltaic panels. And the U-shaped connecting pieces are respectively connected to the two photovoltaic panels on the same side, and the U-shaped openings are oppositely arranged and are fixedly connected with the connecting pieces on the outer sides. The photovoltaic panel connecting structure is connected to the adjacent photovoltaic panels through a lap joint method, stable connection is achieved while punching of the photovoltaic panels is avoided, and the photovoltaic panel connecting structure is simple in structure, few in accessories, convenient to mount and dismount, capable of adapting to different photovoltaic panel intervals and remarkable in effect.

The utility model discloses a dual-mode compatible energy storage case stacking structure which comprises a bottom plate, a first middle partition plate, a second middle partition plate and a top plate are sequentially arranged above the bottom plate, and case bodies are stacked among the bottom plate, the first middle partition plate, the second middle partition plate and the top plate. After the case body is placed on the surface of the bottom plate, the case body can abut against the outer sides of the side plates and the fixing rods, the position of the case body is limited, a worker can conveniently push the case body in the position, the first middle partition plate, the second middle partition plate and the top plate can be sequentially stacked on the bottom plate upwards in the follow-up process, and the work efficiency is improved. Then a first bolt rotates in a first threaded hole, one end of the first bolt is tightly attached to the outer side of the shaft body, the baffle can be tightly attached to the outer side of the case body, then a T-shaped block rotates in a T-shaped groove, a second bolt is meshed with the interior of a second threaded hole, and a breast board can be tightly attached to the outer sides of the bottom plate, the first middle partition plate, the second middle partition plate and the top plate; therefore, tight connection of the whole structure is completed.
