Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment protection fences, in particular to an electric power equipment protection fence. Background Art

[0002] Power equipment mainly includes two categories: power generation equipment and power supply equipment. Power generation equipment mainly includes power station boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment mainly includes transmission lines of various voltage levels, mutual inductors, contactors, etc. For a long time, my country's power system has implemented a regular maintenance system for power equipment, that is, equipment inspection and maintenance according to the planned time cycle. Since power equipment is in an energized state, protective fences need to be installed around the power equipment during inspection and maintenance to protect passers-by.

[0003] The existing power equipment protection fence is troublesome to assemble and requires the help of additional tools for assembly. It has a fixed shape and a large size, which is not convenient for storage and transportation. During the construction of power equipment, there will be certain adjustments in the construction scope. After the existing power equipment protection fence is assembled, it is troublesome to move it over a short distance and it requires manpower to lift and transfer, which is quite laborious. Therefore, a power equipment protection fence is proposed to address the above problems. Utility Model Content

The second limiting block and the limiting plate can prevent the connecting rod from falling off from the fixing rod. Afterwards, under the action of the rotating block, the rotating shaft and the connecting plate, the telescopic rod and the connecting rod are bent at 90 degrees, and then the clamping block and the engaging plate on the other set of fixing rods are engaged. The rod is clamped and fixed, and after being fixed, a bolt is passed through the third limiting hole, and then the second limiting hole is screwed on, which can effectively prevent the clamp block from loosening and falling off, making the guardrail connection more stable. When it needs to be folded up, the clamp block is pulled out from the clamping rod, and then the telescopic rod and the connecting rod are straightened under the action of the connecting plate, the rotating shaft and the rotating block, and then the telescopic rod and the connecting rod are pressed down by the clamp block, and retracted into the fixed rod for convenient transportation, thereby solving the problem that the existing power equipment protection fence is troublesome to assemble, requires the help of additional tools for assembly, has a fixed shape, is large in size, and is not convenient for storage and transportation;

[0013] 2. In the utility model, by setting the base, the first limit groove, the first limit block, the first limit hole, the fixing pin and the universal wheel and other components, when the guardrail needs to be moved, the fixing pin is first pulled out, the first limit block is rotated downward ninety degrees, and then the fixing pin is passed through the first limit hole on the base and the first limit block. After adjustment, the guardrail can be freely moved through the universal wheel, thereby solving the problem that during the construction of power equipment, there will be a certain adjustment in the construction range. After the existing power equipment protection fence is assembled, it is more troublesome to move it over a short distance, and it needs manpower to lift and transfer, which is more laborious.
