[0002] At present, various power engineering projects are developing energy storage systems on a large scale, and battery cabins are often used. After the construction of the basic manhole door is completed, the wellhead is usually simply protected by objects such as partitions. This existing protective device partition cannot withstand a lot of force when it is not fixed. It is easy to be washed away by rain on rainy days and easily blown away in the case of strong wind and sand. There are great safety hazards to the construction site. If temporary heavy protective device partitions are used, it is time-consuming and labor-intensive to fix them, and it is not easy to fix them. It is also troublesome to open and disassemble them later. Secondly, if items need to be lifted or water needs to be pumped in the well, the temporary cover needs to be repeatedly lifted. If a worker makes a mistake at this time, it is easy to fall into the pipe well, endangering the worker's life safety.
