To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the invention have been omitted.

As shown in figures 1-2, a transition cabin for online overhaul of a grid type cooling machine air chamber comprises a cabin body 1, rollers 2, a flexible expansion joint 4, a sealing piece 5, a magnetic seat flange 6 and a magnetic seat switch 7; the flexible expansion joint 4 is arranged on the right side of the cabin body 1, and the opening at the left end of the flexible expansion joint 4 is hermetically connected with the opening at the right end of the cabin body 1; the rollers 2 are multiple, and the rollers 2 are all fixed at the bottom of the cabin 1 to realize the free movement of the cabin 1; the sealing element 5 is fixed at the opening at the right end of the flexible expansion joint 4; the magnetic base switch 7 is arranged on the magnetic base flange 6 and can enable the magnetic base flange 6 to generate magnetism and adjust the strength of the magnetism, and the right end of the flexible expansion joint 4 is adsorbed at the left end of the magnetic base flange 6 under the magnetic action generated by the magnetic base flange 6 and is in sealing connection with the help of the sealing piece 5.

The outer walls of the front side and the rear side of the cabin body 1 are respectively fixed with a hook 3.

An annular conical ring 51 is formed outwards on the outer end surface of the sealing element 5, correspondingly, a conical groove 61 is formed in the left end of the magnetic base flange 6, and the conical ring 51 is inserted into the conical groove 61.

The working principle is as follows:

the right end of the magnetic base flange 6 is fixed at an access door of the air chamber in a sealing way; move the cabin body 1 to the left side of magnetic force seat flange 6 and make the right-hand member opening part of flexible expansion joint 4 aim at the left end of magnetic force seat flange 6 with the help of a plurality of gyro wheels 2, open magnetic force seat switch 7 so that magnetic force seat flange 6 produces magnetic force, and then produce suction to the right-hand member opening part of flexible expansion joint 4, flexible expansion joint 4 slightly expandes under magnetic force so that the right-hand member opening part of flexible expansion joint 4 slowly is close to the left end of magnetic force seat flange 6, adsorb the left end at magnetic force seat flange 6 and reach sealed effect with the help of sealing member 5 completely up to the right-hand member opening part of flexible expansion joint 4.

The cabin body 1 is pushed to move towards the wind chamber so as to slowly compress the flexible expansion joint 4, after the cabin body is moved to a certain position, the two hooks 3 are respectively hooked in the ear rings arranged at the front side and the rear side of the magnetic base flange 6, so that the cabin body 1 is fixed on the magnetic base flange 6 so as to prevent the flexible expansion joint 4 from being separated from the magnetic base flange 6 due to external force, and further, the connection stability is ensured and the sealing performance of the cabin body is ensured.

The invention utilizes the magnetic force generated by the magnetic base flange 6 to realize the adsorption connection with the flexible expansion joint 4, thereby detachably fixing the cabin body 1 on the air chamber access door, and when the air chamber access door is not used, the cabin body 1 can be detached to avoid permanently occupying the inspection space outside the air chamber, thereby ensuring the normal inspection; and personnel and machines can conveniently and quickly finish moving before the cabin body 1 is fixed, thereby greatly facilitating the overhaul.
