Problems solved by technology

Although the energy consumption of a single electromagnet is not high, due to the extensive use of the hydraulic system, the sum of the energy consumption of the electromagnets on each device is quite high, which limits the further improvement of the equipment's battery life

Abstract

The invention discloses a miniature self-locking electromagnet. The electromagnet comprises a permanent magnet which is movably arranged in a shell with an opening formed in one end, an elastic part is arranged between the permanent magnet and the shell, and the telescopic direction of the elastic part points to the opening of the shell; the shell is provided with an electromagnetic coil which drives the permanent magnet to move in the telescopic direction of the elastic part through positive and negative instantaneous energization; an adsorption piece attracted with the permanent magnet is arranged between the outer side of the elastic part and the shell. The adsorption piece is arranged at certain distance from the permanent magnet, when the permanent magnet moves under the action of theelectromagnetic coil, the distance and interaction force between the permanent magnet and the adsorption piece are changed, and then the acting force energy between the permanent magnet and the adsorption piece becomes larger or smaller than reset force applied to the permanent magnet by other parts, automatic locking of the on-off state of the electromagnet is achieved, even though the electromagnet is powered off, movement cannot occur, and power consumption of equipment is lowered.

Description

technical field [0001] The invention relates to the field of electromagnetic valve structure, in particular to a miniature self-locking electromagnet. Background technique [0002] In recent years, in order to ensure the stable supply of fossil fuels and improve the level of exploration operations, the country has significantly increased its research and development investment in downhole drilling and logging technology tools. With the in-depth research and development of application technology, a large number of new downhole drilling logging tools have been developed and put into use, such as formation pressure measurement system while drilling, electro-hydraulic drive intelligent switch sleeve, etc. In order to reduce the shackles of cables and better move underground, many equipment choose to carry batteries, so that they can move more flexibly and display working parts for operations. Due to the harsh environment of high temperature and high pressure underground, and th...
