[0026] The superimposed telescopic rod body can make the second limiting protrusion on the supporting tank body touch the elastic buckle on the first-stage telescopic sleeve and open when the first-stage telescopic sleeve extends, so that the second-stage telescopic sleeve extends under the action of the compression spring, and repeats this process repeatedly, finally making all the telescopic sleeves realize the extension linkage action in turn, completing the extension support operation of the entire supporting equipment.

[0027] The support device also includes an electromagnetic drive mechanism 6, which includes an induction coil 601 and an electromagnetic movable part 602; an movable cavity 105 is arranged on the side wall of the support tank body 1 and the movable cavity 105 is located at the periphery of the third pulling rope 705, and the third pulling rope 705 passes through the movable cavity 105 and is connected with the telescopic buckle 5; the induction coil 601 is sleeved on the periphery of the support tank body 1 and is arranged corresponding to the movable cavity 105; an electromagnetic movable part 602 is arranged in the movable cavity 105 and the electromagnetic movable part 602 can slide longitudinally in the movable cavity 105, and a magnet 603 is arranged on the electromagnetic movable part 602, which is arranged corresponding to the induction coil 601 and can drive the electromagnetic movable part 602 to squeeze the third pulling rope 705 under the action of the Lorentz force.

After the induction coil is energized, it can drive the magnet and the electromagnetic moving parts to move up and down in the moving cavity. When moving, it will cause an extrusion and pulling effect on the third pulling rope. When the third pulling rope is pulled, the telescopic buckle will open, and the second pulling rope will be pulled simultaneously to open the pulling lock, thereby achieving the technical effect of opening the telescopic buckle and the pulling lock at the same time, so that the supporting equipment can quickly perform the extension and support operation.

The pressing plate can press the pulling buttons on multiple supporting tanks at the same time, so that the superimposed telescopic rods in the multiple tanks can achieve synchronous extension and support actions.

[0030] The containment ring can be used as a reference point for external connection of the supporting equipment. It can be assembled with external supporting components (such as pressure-bearing steel plates, appropriate columns, etc.) through splicing, welding and other methods to form emergency pressure protection equipment. There will be no less than three groups of supporting tanks fixedly installed on the containment ring. This can make up for the defects of the supporting equipment such as small size and insufficient pressure limit, and improve its support stability.

[0031] In addition, this embodiment also discloses a working method of the above-mentioned supporting device, which includes the following steps: S1. When the pressing plate is pressed manually or the natural environment sensor drives the electromagnetic movable part to move via the induction coil, the first pulling rope, the second pulling rope and the third pulling rope are pulled in linkage, so that the pulling lock buckle and the telescopic buckle are in the open state; S2. After the telescopic buckle is opened, the piston moves downward rapidly under the action of the high-pressure power source and squeezes the top of the first-stage telescopic sleeve; S3, after the pull lock is opened, the positioning spring pushes the first-stage telescopic sleeve and the positioning rod downward under the elastic action; S4.

S7, repeat this process until all telescopic sleeves have been moved downward, thus achieving a fast supporting operation of the supporting equipment.

The "high-voltage power source" part is used as the main force generating part, and a manual switch button is established. It can be combined with a variety of load-bearing steel plates or other materials to quickly form emergency protection equipment. Under the joint action of the high-voltage power source and the spring, the extension support action can be quickly realized during the support operation, the support rate is faster, and the pressure-bearing effect is more significant; and its volume is smaller in the folded state, which can be conveniently carried.

The telescopic electromagnetic and high voltage linkage support device according to claim 7, characterized in that: An injection port is arranged on the side wall of the supporting tank body, the injection port is located between the top end of the piston and the top baffle, and a one-way injection valve is arranged in the injection port.

9. The telescopic electromagnetic and high voltage linkage support device according to claim 8, characterized in that: The high-pressure power source is high-pressure hydraulic oil or high-pressure gas or a mixture of high-pressure hydraulic oil and high-pressure gas.

10. A working method of the telescopic electromagnetic and high voltage linkage support device according to claim 9, characterized in that: The following steps are involved: S1. When the pressing plate is pressed manually or the natural environment sensor drives the electromagnetic movable part to move via the induction coil, the first pulling rope, the second pulling rope and the third pulling rope are pulled in linkage, so that the pulling lock buckle and the telescopic buckle are in the open state; S2. After the telescopic buckle is opened, the piston moves downward rapidly under the action of the high-pressure power source and squeezes the top of the first-stage telescopic sleeve; S3, after the pull lock is opened, the positioning spring pushes the first-stage telescopic sleeve and the positioning rod downward under the elastic action; S4. Under the simultaneous action of the high-pressure power source and the positioning spring, the first-stage telescopic sleeve and the multi-stage telescopic sleeve sleeved in the first-stage telescopic sleeve move downward rapidly together until the first limiting protrusion on the first-stage telescopic sleeve contacts the second limiting protrusion on the supporting tank body and is engaged and positioned through the positioning buckle; S5. When the first-stage telescopic sleeve moves downward, the second limiting protrusion on the supporting tank body contacts the elastic buckle on the side wall of the first-stage telescopic sleeve and makes the elastic buckle in an open state; S6. After the elastic buckle is opened, the second-stage telescopic sleeve moves downward rapidly under the action of the compression spring until the first limiting protrusion on the second-stage telescopic sleeve contacts the second limiting protrusion on the first-stage telescopic sleeve and is engaged and positioned through the positioning buckle. During the movement, the second limiting protrusion on the first-stage telescopic sleeve contacts the elastic buckle on the side wall of the second-stage telescopic sleeve and the elastic buckle is in an open state. S7, repeat this process until all telescopic sleeves have been moved downward, thus achieving a fast supporting operation of the supporting equipment.
