When two poles (N or S) of the strong magnetic material are in the vertical direction, namely the N or S pole of the magnet is opposite to the soft magnetic material base, the soft magnetic material base is magnetized, and the base has strong magnetism and can be used for attracting the surface of steel. When the two poles of the magnet are in the horizontal direction and the middle of the magnet N, S is opposite to the soft magnetic material base, the magnetic force on the base is almost not generated because the middle of the strip-shaped magnet has only very small magnetism and can be ignored, and the base can not be magnetized, so that the magnet can be easily taken off from the surface of the steel. In the accommodation process, when transferring to the knob clockwise turning, strong magnetic material for fixing base bottom surface angle increase, strong magnetic material NS utmost point and fixing base bottom surface level gradually, the base loses the adsorption affinity gradually. When turning to knob anticlockwise rotation, strong magnetic material reduces for fixing base bottom surface angle, and strong magnetic material NS utmost point is perpendicular gradually with the fixing base bottom surface, and the base adsorption affinity slowly reaches the biggest, plays the adsorption.
The manhole in the limited space is opened, and the manhole is operated according to the following steps when the manhole is at risk;
1. the unlocking component used for the invention can be a key, a lock hole with a locking knob rotation function is opened, and the direction-adjusting gear knob can be rotated by opening the lock hole;
2. after a proper position is selected to enable the adjustable magnetic force fixing seat to be tightly attached to the surface of the manhole flange, the direction-adjusting gear knob is rotated to enable the strong magnetic material on the adjustable magnetic force fixing seat to have magnetic force to tightly absorb the manhole flange;
3. pulling the telescopic isolation belt to enable the other adjustable magnetic force fixing seat to be located at a proper position on the other side of the manhole flange;
4. repeating the steps 1-2 to complete the installation of another adjustable magnetic force fixing seat;
5. locking the lockholes with the rotating functions of the two locking knobs by using a key;
6. repeating the steps 1-5 to install another group of the invention which is vertically arranged with the former group;
7. and after the installation is finished, the key is handed to a field manager.
The method is operated according to the following steps when the limited space operation condition is obtained and the method needs to be relieved:
1. the unlocking key is obtained to a field administrator by a limited space operation ticket;
2. the key is used for opening the lock holes with the locking knob rotation function one by one;
3. the direction-adjusting gear knobs are rotated one by one to enable the strong magnetic materials on the adjustable magnetic force fixing seats to be turned upwards and then are released one by one.
The application scenarios of the invention are as follows:
1. the manhole of the container is opened during equipment maintenance, and the container is ventilated and replaced;
2. the operation ticket in the limited space is not approved;
3. a limited space job interruption period;
4. during idle container and manhole open;
5. manhole for skirt of tower and tank;
6. other areas where a limited risk may occur.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art.
