4. A power line field survey apparatus as claimed in claim 3 wherein: the butt joint plate is perpendicular to the sealing plate and is in butt joint with the butt joint plate on the adjacent sealing plate; concave-convex structures matched with each other are arranged between the butt joint plates which are mutually butted; and sealing gaskets are arranged between the butt joint plates which are mutually butted.
5. A power line field survey apparatus as claimed in claim 3 wherein: when the sealing plate slides to close the opening, the other end of the inner abutting rod is used for abutting against the abutting plate; the inner wall of the protective cover and the butt plate are both provided with chute pieces, the chute pieces are provided with limiting chutes, and the limiting chutes are used for limiting the movement track of the end part of the inner butt joint rod in a preset track.
6. The power line field survey apparatus of claim 1 wherein: the outer end of the pull rope is provided with a pull ring, and the pull ring is clamped with the sealing plate through a clamping structure; the locking component comprises two rotating connecting rods, the two rotating connecting rods are arranged in parallel, and the first elastic piece comprises a torsion spring sleeved on the rotating shaft of the rotating connecting rod; the outer end of the sealing plate is provided with a baffle plate which is used for shielding the avoidance groove at the outer side when the sealing plate slides to close the opening.
7. The power line field survey apparatus of claim 1 wherein: the number of the air bags is multiple and the air bags are communicated with each other; the inflation tube is connected with one of the airbags.
