[0043] Working principle:

[0044] Step one, according to the estimated size range of the pipe well door opening 5, select the appropriate adjustable pipe well door opening protective device. Ensure that the adjusting assembly 1, protective net 2 and frame assembly 3 and other parts of the protective device are undamaged, and the accessories are complete.

[0045] Step two, place the fixed frame 301 at one side edge of the pipe well door opening 5 to preliminarily position it. By operating the adjusting rod 102, drive the sliding block 101 connected with the end of the sliding frame 302 to slide in the sliding groove 304, adjust the extension length of the sliding frame 302 relative to the fixed frame 301 according to the actual size of the pipe well door opening 5, so that the overall size of the frame assembly 3 adapts to the opening. After determining the size of the frame assembly 3, place the frame assembly 3 around the pipe well door opening 5, so that the fixed frame 301 and the sliding frame 302 are aligned with the edge of the opening. Use the expansion bolts 4 to pass through the mounting holes of the frame assembly 3, and screw into the wall or ground around the pipe well door opening 5, and tighten the expansion bolts 4 to firmly fix the frame assembly 3 at the pipe well door opening 5. During the fixing process, pay attention to ensure the levelness and perpendicularity of the frame assembly 3.
