Fixing bolts are arranged on the outer walls of the fixing lugs and the outer wall of the fastening sleeve box in a penetrating mode, and a loosening assembly is arranged between the fixing bolts and the outer surface of the fastening sleeve box. According to the I-shaped steel fixing device, the loosening assemblies are arranged, so that the fixing bolts are not prone to loosening under the action of the loosening assemblies after the fixing bolts are fixed, and the two fixing lugs can effectively fasten the joint between the two pieces of I-shaped steel continuously for a long time; and meanwhile, a user can complete dismounting of the fixing bolt and the loosening assembly through direct reverse rotation, the fixing bolt and the loosening assembly can be recycled conveniently, and the practicability of the device is improved.

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.

The utility model discloses a power cable construction installation adjusting frame, which relates to the technical field of cable installation, and comprises a bottom plate, the left end of the upper side of the bottom plate is fixedly connected with a fixing frame, the front side and the rear side of the fixing frame are both provided with a plurality of positioning holes, the right side of the fixing frame is provided with an installation plate, and the installation plate comprises a telescopic plate body. Positioning plates are fixedly connected to the front side and the rear side of the left end of the telescopic plate body, a sliding rail is arranged at the left end of the upper side of the telescopic plate body, a first sliding plate is slidably connected to the front end in the sliding rail, and a second sliding plate is slidably connected to the rear end in the sliding rail. According to the utility model, through the arrangement of the telescopic plate, the baffle plate and the fastening bolt, a plurality of cables or cables with different diameters can be effectively installed at the same time, and through the arrangement of the lifting threaded rod, the rotating handle, the lifting hole, the first sliding plate and the second sliding plate, the installation height of each cable can be changed at will, so that the distance between the cables meets the requirement, and the installation efficiency is improved. The mounting space is saved as much as possible.
