Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

Example 1

As shown in fig. 1 and 2, an electromagnetic type bandage fastening leaking stoppage fixture comprises an electromagnetic force applying device 1, a plugging cap 2 and a manual fastening assembly 3, wherein the electromagnetic force applying device 1 is an electromagnet, a groove 11 is formed in one surface, connected with a pipeline 4, of the electromagnetic force applying device, the plugging cap 2 is placed in the groove 11, when the electromagnetic force applying device works, the lower end of the plugging cap is pressed at a damaged position of the pipeline 4, a through hole is formed in the plugging cap 2, the manual fastening assembly 3 comprises a bandage 31 penetrating through the through hole in the plugging cap 2 and fastening joints 32 connected to two ends of the bandage 31, and the fastening joints 32 are connected through fastening bolts 33. To accommodate conduits of different diameters, the strap 31 may be replaced with straps of different lengths and widths.

Specifically, the electromagnetic force applying device 1 includes an iron core 12, the iron core 12 is in a rectangular parallelepiped shape, two coil winding posts 13 are disposed at the upper end of the iron core 12, the coil is wound on the coil winding posts 13, and the coil is connected to a power supply 14. The power supply 14 is a 48V power supply which supplies power to the coil and generates electromagnetic force by utilizing the principle of electromagnetism generation, thereby compressing the pipeline 4.

Compared with the existing plugging mode, the magnetic plugging device changes the characteristic of magnetic adsorption force by changing the distance between the permanent magnet and the adsorbed object. The utility model discloses in, electromagnetism force applicator 1 uses repeatedly in can the short time, only needs to prepare many sets of shutoff caps 2 and manual fastening components 3, alright carry out many shutoff. When the electromagnetic force applicator 1 is electrified to generate electromagnetic force, the iron core 12 can compress the pipeline, and when the power is off, the electromagnetic force disappears, so that the iron core 12 is separated from the pipeline 4.
