The invention discloses high-intensity magnetic field positioning high-pressure balancing leaking stoppage equipment which comprises high-intensity direct current permanent-magnet suction discsuction cup capable of being strongly attracted with paramagnetic materials such as a ship hull, a storage tank, a tank car and a petrochemical pipeline, a sealing capsule, a metal housing and a pressure adjustment lead screw. The high-intensity direct current permanent-magnet suction discsuction cup generates or eliminates a high-intensity magnetic field instantly through a 24V control circuit, and the sealing capsule belongs to a flexible braided rubber hollow high pressure resistant expansion body, and is supercharged by solid and liquid glue and nitrogen. The metal housing is used for controlling an expansion direction of the sealing capsule; a pressure adjustment handle drives the lead screw to be connected with the metal housing and has a mechanical pressure adjustment function; the high-intensity direct current permanent-magnet suction discsuction cup can be independently used for the leaking stoppage equipment; or the high-intensity direct current permanent-magnet suction discsuction cups can be combined to be used for the leaking stoppage equipment. The equipment has the advantages that a high-intensity magnetic field force is adjustable, free attracted positioning is achieved, the high-pressure balancing of the sealing capsule is used for blocking medium leakage, and the equipment solves the problems that the existing permanent-magnet leaking stoppage tool cannot change position quickly or block medium undercurrent.

The invention discloses a movable transport frame for maintaining of power generating equipment. The movable transport frame comprises a bottom frame. Support plates are arranged on the two sides of the bottom frame. A connecting frame rod is matched between the tops of the two support plates. First screws are matched between the connecting frame rod and the support plates. L-shaped supporting grooves are formed in the faces of the support plates. A groove is formed in the tops of the supporting grooves. A suspension rod is matched in the supporting grooves. A carriage is arranged on the top of the bottom frame. A hydraulic cylinder is arranged on the top of the carriage and provided with two parallel output ends, and the output ends abut against the suspension rod. When the movable transport frame is used, the suspension rod can be lifted through assistance of hydraulic oil, lifting of the power generating equipment is finished, then, the suspension rod is matched in the groove by moving the carriage, and the hydraulic oil can be recycled after matching is finished. The supporting state does not need to be kept all the time, using is safer, and meanwhile the movable transport frame is small in size and convenient to move.
